<h2 id="introduction">Introduction</h2>
<p>This is a collection of rules, guidelines, and suggestions for writing HotSpot code. Following these will help new code fit in with existing HotSpot code, making it easier to read and maintain. Failure to follow these guidelines may lead to discussion during code reviews, if not outright rejection of a change.</p>
<h3 id="why-care-about-style">Why Care About Style?</h3>
<p>Some programmers seem to have lexers and even C preprocessors installed directly behind their eyeballs. The rest of us require code that is not only functionally correct but also easy to read. More than that, since there is no one style for easy-to-read code, and since a mashup of many styles is just as confusing as no style at all, it is important for coders to be conscious of the many implicit stylistic choices that historically have gone into the HotSpot code base.</p>
<p>Some of these guidelines are driven by the cross-platform requirements for HotSpot. Shared code must work on a variety of platforms, and may encounter deficiencies in some. Using platform conditionalization in shared code is usually avoided, while shared code is strongly preferred to multiple platform-dependent implementations, so some language features may be recommended against.</p>
<p>Some of the guidelines here are relatively arbitrary choices among equally plausible alternatives. The purpose of stating and enforcing these rules is largely to provide a consistent look to the code. That consistency makes the code more readable by avoiding non-functional distractions from the interesting functionality.</p>
<p>When changing pre-existing code, it is reasonable to adjust it to match these conventions. Exception: If the pre-existing code clearly conforms locally to its own peculiar conventions, it is not worth reformatting the whole thing. Also consider separating changes that make extensive stylistic updates from those which make functional changes.</p>
<h3 id="counterexamples-and-updates">Counterexamples and Updates</h3>
<p>Many of the guidelines mentioned here have (sometimes widespread) counterexamples in the HotSpot code base. Finding a counterexample is not sufficient justification for new code to follow the counterexample as a precedent, since readers of your code will rightfully expect your code to follow the greater bulk of precedents documented here.</p>
<p>Occasionally a guideline mentioned here may be just out of synch with the actual HotSpot code base. If you find that a guideline is consistently contradicted by a large number of counterexamples, please bring it up for discussion and possible change. The architectural rule, of course, is &quot;When in Rome do as the Romans&quot;. Sometimes in the suburbs of Rome the rules are a little different; these differences can be pointed out here.</p>
<p>Proposed changes should be discussed on the <a href="mailto:hotspot-dev@openjdk.java.net">HotSpot Developers</a> mailing list, and approved by <a href="https://en.wikipedia.org/wiki/Rough_consensus">rough consensus</a> of the <a href="https://openjdk.java.net/census#hotspot">HotSpot Group</a> Members. The Group Lead determines whether consensus has been reached. Changes are likely to be cautious and incremental, since HotSpot coders have been using these guidelines for years.</p>
<h2 id="structure-and-formatting">Structure and Formatting</h2>
<h3 id="factoring-and-class-design">Factoring and Class Design</h3>
<ul>
<li><p>Group related code together, so readers can concentrate on one section of one file.</p></li>
<li><p>Classes are the primary code structuring mechanism. Place related functionality in a class, or a set of related classes. Use of either namespaces or public non-member functions is rare in HotSpot code. Static non-member functions are not uncommon.</p></li>
<li><p>If a class <code>FooBar</code> is going to be used in more than one place, put it a file named fooBar.hpp and fooBar.cpp. If the class is a sidekick to a more important class <code>BazBat</code>, it can go in bazBat.hpp.</p></li>
<li><p>Put a member function <code>FooBar::bang</code> into the same file that defined <code>FooBar</code>, or its associated <em>.inline.hpp or </em>.cpp file.</p></li>
<li><p>Use public accessor functions for member variables accessed outside the class.</p></li>
<li><p>Assign names to constant literals and use the names instead.</p></li>
<li><p>Keep functions small, a screenful at most. Split out chunks of logic into file-local classes or static functions if needed.</p></li>
<li><p>Factor away nonessential complexity into local inline helper functions and helper classes.</p></li>
<li><p>Think clearly about internal invariants that apply to each class, and document them in the form of asserts within member functions.</p></li>
<li><p>Make simple, self-evident contracts for member functions. If you cannot communicate a simple contract, redesign the class.</p></li>
<li><p>Implement classes as if expecting rough usage by clients. Check for incorrect usage of a class using <code>assert(...)</code>, <code>guarantee(...)</code>, <code>ShouldNotReachHere()</code> and comments wherever needed. Performance is almost never a reason to omit asserts.</p></li>
<li><p>When possible, design as if for reusability. This forces a clear design of the class's externals, and clean hiding of its internals.</p></li>
<li><p>Initialize all variables and data structures to a known state. If a class has a constructor, initialize it there.</p></li>
<li><p>Do no optimization before its time. Prove the need to optimize.</p></li>
<li><p>When you must defactor to optimize, preserve as much structure as possible. If you must hand-inline some name, label the local copy with the original name.</p></li>
<li><p>If you need to use a hidden detail (e.g., a structure offset), name it (as a constant or function) in the class that owns it.</p></li>
<li><p>Don't use the Copy and Paste keys to replicate more than a couple lines of code. Name what you must repeat.</p></li>
<li><p>If a class needs a member function to change a user-visible attribute, the change should be done with a &quot;setter&quot; accessor matched to the simple &quot;getter&quot;.</p></li>
</ul>
<h3 id="source-files">Source Files</h3>
<ul>
<li><p>All source files must have a globally unique basename. The build system depends on this uniqueness.</p></li>
<li><p>Do not put non-trivial function implementations in .hpp files. If the implementation depends on other .hpp files, put it in a .cpp or a .inline.hpp file.</p></li>
<li><p>.inline.hpp files should only be included in .cpp or .inline.hpp files.</p></li>
<li><p>All .cpp files include precompiled.hpp as the first include line.</p></li>
<li><p>precompiled.hpp is just a build time optimization, so don't rely on it to resolve include problems.</p></li>
<li><p>Keep the include lines alphabetically sorted.</p></li>
<li><p>Put conditional inclusions (<code>#if ...</code>) at the end of the include list.</p></li>
</ul>
<h3 id="jtreg-tests">JTReg Tests</h3>
<ul>
<li><p>JTReg tests should have meaningful names.</p></li>
<li><p>JTReg tests associated with specific bugs should be tagged with the <code>@bug</code> keyword in the test description.</p></li>
<li><p>JTReg tests should be organized by component or feature under <code>test/</code>, in a directory hierarchy that generally follows that of the <code>src/</code> directory. There may be additional subdirectories to further categorize tests by feature. This structure makes it easy to run a collection of tests associated with a specific feature by specifying the associated directory as the source of the tests to run.</p>
<ul>
<li>Some (older) tests use the associated bug number in the directory name, the test name, or both. That naming style should no longer be used, with existing tests using that style being candidates for migration.</li>
</ul></li>
</ul>
<h3 id="naming">Naming</h3>
<ul>
<li><p>The length of a name may be correlated to the size of its scope. In particular, short names (even single letter names) may be fine in a small scope, but are usually inappropriate for larger scopes.</p></li>
<li><p>Prefer whole words rather than abbreviations, unless the abbreviation is more widely used than the long form in the code's domain.</p></li>
<li><p>Choose names consistently. Do not introduce spurious variations. Abbreviate corresponding terms to a consistent length.</p></li>
<li><p>Global names must be unique, to avoid <a href="https://en.cppreference.com/w/cpp/language/definition" title="One Definition Rule">One Definition Rule</a> (ODR) violations. A common prefixing scheme for related global names is often used. (This is instead of using namespaces, which are mostly avoided in HotSpot.)</p></li>
<li><p>Don't give two names to the semantically same thing. But use different names for semantically different things, even if they are representationally the same. (So use meaningful <code>typedef</code> or template alias names where appropriate.)</p></li>
<li><p>When choosing names, avoid categorical nouns like &quot;variable&quot;, &quot;field&quot;, &quot;parameter&quot;, &quot;value&quot;, and verbs like &quot;compute&quot;, &quot;get&quot;. (<code>storeValue(int param)</code> is bad.)</p></li>
<li><p>Type names and global names should use mixed-case with the first letter of each word capitalized (<code>FooBar</code>).</p></li>
<li><p>Embedded abbreviations in otherwise mixed-case names are usually capitalized entirely rather than being treated as a single word with only the initial letter capitalized, e.g. &quot;HTML&quot; rather than &quot;Html&quot;.</p></li>
<li><p>Function and local variable names use lowercase with words separated by a single underscore (<code>foo_bar</code>).</p></li>
<li><p>Class data member names have a leading underscore, and use lowercase with words separated by a single underscore (<code>_foo_bar</code>).</p></li>
<li><p>Constant names may be upper-case or mixed-case, according to historical necessity. (Note: There are many examples of constants with lowercase names.)</p></li>
<li><p>Constant names should follow an existing pattern, and must have a distinct appearance from other names in related APIs.</p></li>
<li><p>Class and type names should be noun phrases. Consider an &quot;er&quot; suffix for a class that represents an action.</p></li>
<li><p>Function names should be verb phrases that reflect changes of state known to a class's user, or else noun phrases if they cause no change of state visible to the class's user.</p></li>
<li><p>Getter accessor names are noun phrases, with no &quot;<code>get_</code>&quot; noise word. Boolean getters can also begin with &quot;<code>is_</code>&quot; or &quot;<code>has_</code>&quot;. Member function for reading data members usually have the same name as the data member, exclusive of the leading underscore.</p></li>
<li><p>Setter accessor names prepend &quot;<code>set_</code>&quot; to the getter name.</p></li>
<li><p>Other member function names are verb phrases, as if commands to the receiver.</p></li>
<li><p>Avoid leading underscores (as &quot;<code>_oop</code>&quot;) except in cases required above. (Names with leading underscores can cause portability problems.)</p></li>
</ul>
<h3 id="commenting">Commenting</h3>
<ul>
<li><p>Clearly comment subtle fixes.</p></li>
<li><p>Clearly comment tricky classes and functions.</p></li>
<li><p>If you have to choose between commenting code and writing wiki content, comment the code. Link from the wiki to the source file if it makes sense.</p></li>
<li><p>As a general rule don't add bug numbers to comments (they would soon overwhelm the code). But if the bug report contains significant information that can't reasonably be added as a comment, then refer to the bug report.</p></li>
<li><p>Personal names are discouraged in the source code, which is a team product.</p></li>
</ul>
<h3 id="macros">Macros</h3>
<ul>
<li><p>You can almost always use an inline function or class instead of a macro. Use a macro only when you really need it.</p></li>
<li><p>Templates may be preferable to multi-line macros. (There may be subtle performance effects with templates on some platforms; revert to macros if absolutely necessary.)</p></li>
<li><p><code>#ifdef</code>s should not be used to introduce platform-specific code into shared code (except for <code>_LP64</code>). They must be used to manage header files, in the pattern found at the top of every source file. They should be used mainly for major build features, including <code>PRODUCT</code>, <code>ASSERT</code>, <code>_LP64</code>, <code>INCLUDE_SERIALGC</code>, <code>COMPILER1</code>, etc.</p></li>
<li><p>For build features such as <code>PRODUCT</code>, use <code>#ifdef PRODUCT</code> for multiple-line inclusions or exclusions.</p></li>
<li><p>For short inclusions or exclusions based on build features, use macros like <code>PRODUCT_ONLY</code> and <code>NOT_PRODUCT</code>. But avoid using them with multiple-line arguments, since debuggers do not handle that well.</p></li>
<li><p>Use <code>CATCH</code>, <code>THROW</code>, etc. for HotSpot-specific exception processing.</p></li>

<li><p>In general, don't change whitespace unless it improves readability or consistency. Gratuitous whitespace changes will make integrations and backports more difficult.</p></li>
<li><p>Use One-True-Brace-Style. The opening brace for a function or class is normally at the end of the line; it is sometimes moved to the beginning of the next line for emphasis. Substatements are enclosed in braces, even if there is only a single statement. Extremely simple one-line statements may drop braces around a substatement.</p></li>
<li><p>Indentation levels are two columns.</p></li>
<li><p>There is no hard line length limit. That said, bear in mind that excessively long lines can cause difficulties. Some people like to have multiple side-by-side windows in their editors, and long lines may force them to choose among unpleasant options. They can use wide windows, reducing the number that can fit across the screen, and wasting a lot of screen real estate because most lines are not that long. Alternatively, they can have more windows across the screen, with long lines wrapping (or worse, requiring scrolling to see in their entirety), which is harder to read. Similar issues exist for side-by-side code reviews.</p></li>
<li><p>Tabs are not allowed in code. Set your editor accordingly.<br> (Emacs: <code>(setq-default indent-tabs-mode nil)</code>.)</p></li>
<li><p>Use good taste to break lines and align corresponding tokens on adjacent lines.</p></li>
<li><p>Use spaces around operators, especially comparisons and assignments. (Relaxable for boolean expressions and high-precedence operators in classic math-style formulas.)</p></li>
<li><p>Put spaces on both sides of control flow keywords <code>if</code>, <code>else</code>, <code>for</code>, <code>switch</code>, etc. Don't add spaces around the associated <em>control</em> expressions. Examples:</p>
<pre><code>while (test_foo(args...)) { // Yes
while(test_foo(args...)) { // No, missing space after while
while ( test_foo(args...) ) { // No, excess spaces around control</code></pre></li>
<li><p>Use extra parentheses in expressions whenever operator precedence seems doubtful. Always use parentheses in shift/mask expressions (<code>&lt;&lt;</code>, <code>&amp;</code>, <code>|</code>). Don't add whitespace immediately inside parentheses.</p></li>
<li><p>Use more spaces and blank lines between larger constructs, such as classes or function definitions.</p></li>
<li><p>If the surrounding code has any sort of vertical organization, adjust new lines horizontally to be consistent with that organization. (E.g., trailing backslashes on long macro definitions often align.)</p></li>
</ul>
<h3 id="miscellaneous">Miscellaneous</h3>
<ul>
<li><p>Use the <a href="https://en.cppreference.com/w/cpp/language/raii" title="Resource Acquisition Is Initialization">Resource Acquisition Is Initialization</a> (RAII) design pattern to manage bracketed critical sections. See class <code>ResourceMark</code> for an example.</p></li>
<li>Avoid implicit conversions to <code>bool</code>.
<ul>
<li>Use <code>bool</code> for boolean values.</li>
<li>Do not use ints or pointers as (implicit) booleans with <code>&amp;&amp;</code>, <code>||</code>, <code>if</code>, <code>while</code>. Instead, compare explicitly, i.e. <code>if (x != 0)</code> or <code>if (ptr != nullptr)</code>, etc.</li>
<li>Do not use declarations in <em>condition</em> forms, i.e. don't use <code>if (T v = value) { ... }</code>.</li>
</ul></li>
<li><p>Use functions from globalDefinitions.hpp and related files when performing bitwise operations on integers. Do not code directly as C operators, unless they are extremely simple. (Examples: <code>align_up</code>, <code>is_power_of_2</code>, <code>exact_log2</code>.)</p></li>
<li><p>Use arrays with abstractions supporting range checks.</p></li>
<li><p>Always enumerate all cases in a switch statement or provide a default case. It is ok to have an empty default with comment.</p></li>
</ul>
<h2 id="use-of-c-features">Use of C++ Features</h2>
<p>HotSpot was originally written in a subset of the C++98/03 language. More recently, support for C++14 is provided, though again, HotSpot only uses a subset. (Backports to JDK versions lacking support for more recent Standards must of course stick with the original C++98/03 subset.)</p>
<p>This section describes that subset. Features from the C++98/03 language may be used unless explicitly excluded here. Features from C++11 and C++14 may be explicitly permitted or explicitly excluded, and discussed accordingly here. There is a third category, undecided features, about which HotSpot developers have not yet reached a consensus, or perhaps have not discussed at all. Use of these features is also excluded.</p>
<p>(The use of some features may not be immediately obvious and may slip in anyway, since the compiler will accept them. The code review process is the main defense against this.)</p>
<p>Some features are discussed in their own subsection, typically to provide more extensive discussion or rationale for limitations. Features that don't have their own subsection are listed in omnibus feature sections for permitted, excluded, and undecided features.</p>
<p>Lists of new features for C++11 and C++14, along with links to their descriptions, can be found in the online documentation for some of the compilers and libraries. The C++14 Standard is the definitive description.</p>

</ul>
<h3 id="error-handling">Error Handling</h3>
<p>Do not use exceptions. Exceptions are disabled by the build configuration for some platforms.</p>
<p>Rationale: There is significant concern over the performance cost of exceptions and their usage model and implications for maintainable code. That's not just a matter of history that has been fixed; there remain questions and problems even today (2019). See, for example, <a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p0709r0.pdf">Zero cost deterministic exceptions</a>. Because of this, HotSpot has always used a build configuration that disables exceptions where that is available. As a result, HotSpot code uses error handling mechanisms such as two-phase construction, factory functions, returning error codes, and immediate termination. Even if the cost of exceptions were not a concern, the existing body of code was not written with exception safety in mind. Making HotSpot exception safe would be a very large undertaking.</p>
<p>In addition to the usual alternatives to exceptions, HotSpot provides its own exception mechanism. This is based on a set of macros defined in utilities/exceptions.hpp.</p>
<h3 id="rtti-runtime-type-information">RTTI (Runtime Type Information)</h3>
<p>Do not use <a href="https://en.wikipedia.org/wiki/Run-time_type_information" title="Runtime Type Information">Runtime Type Information</a> (RTTI). <a href="https://en.wikipedia.org/wiki/Run-time_type_information" title="Runtime Type Information">RTTI</a> is disabled by the build configuration for some platforms. Among other things, this means <code>dynamic_cast</code> cannot be used.</p>
<p>Rationale: Other than to implement exceptions (which HotSpot doesn't use), most potential uses of <a href="https://en.wikipedia.org/wiki/Run-time_type_information" title="Runtime Type Information">RTTI</a> are better done via virtual functions. Some of the remainder can be replaced by bespoke mechanisms. The cost of the additional runtime data structures needed to support <a href="https://en.wikipedia.org/wiki/Run-time_type_information" title="Runtime Type Information">RTTI</a> are deemed not worthwhile, given the alternatives.</p>
<h3 id="memory-allocation">Memory Allocation</h3>
<p>Do not use the standard global allocation and deallocation functions (operator new and related functions). Use of these functions by HotSpot code is disabled for some platforms.</p>
<p>Rationale: HotSpot often uses &quot;resource&quot; or &quot;arena&quot; allocation. Even where heap allocation is used, the standard global functions are avoided in favor of wrappers around malloc and free that support the VM's Native Memory Tracking (NMT) feature.</p>
<p>Native memory allocation failures are often treated as non-recoverable. The place where &quot;out of memory&quot; is (first) detected may be an innocent bystander, unrelated to the actual culprit.</p>
<h3 id="class-inheritance">Class Inheritance</h3>
<p>Use public single inheritance.</p>
<p>Prefer composition rather than non-public inheritance.</p>
<p>Restrict inheritance to the &quot;is-a&quot; case; use composition rather than non-is-a related inheritance.</p>
<p>Avoid multiple inheritance. Never use virtual inheritance.</p>
<h3 id="namespaces">Namespaces</h3>
<p>Avoid using namespaces. HotSpot code normally uses &quot;all static&quot; classes rather than namespaces for grouping. An &quot;all static&quot; class is not instantiable, has only static members, and is normally derived (possibly indirectly) from the helper class <code>AllStatic</code>.</p>
<p>Benefits of using such classes include:</p>
<ul>
<li><p>Provides access control for members, which is unavailable with namespaces.</p></li>
<li><p>Avoids <a href="https://en.cppreference.com/w/cpp/language/adl" title="Argument Dependent Lookup">Argument Dependent Lookup</a> (ADL).</p></li>
<li><p>Closed for additional members. Namespaces allow names to be added in multiple contexts, making it harder to see the complete API.</p></li>
</ul>
<p>Namespaces should be used only in cases where one of those &quot;benefits&quot; is actually a hindrance.</p>
<p>In particular, don't use anonymous namespaces. They seem like they should be useful, and indeed have some real benefits for naming and generated code size on some platforms. Unfortunately, debuggers don't seem to like them at all.</p>
<p><a href="https://groups.google.com/forum/#!topic/mozilla.dev.platform/KsaG3lEEaRM" class="uri">https://groups.google.com/forum/#!topic/mozilla.dev.platform/KsaG3lEEaRM</a><br> Suggests Visual Studio debugger might not be able to refer to anonymous namespace symbols, so can't set breakpoints in them. Though the discussion seems to go back and forth on that.</p>

<h3 id="c-standard-library">C++ Standard Library</h3>
<p>Avoid using the C++ Standard Library.</p>
<p>Historically, HotSpot has mostly avoided use of the Standard Library.</p>
<p>(It used to be impossible to use most of it in shared code, because the build configuration for Solaris with Solaris Studio made all but a couple of pieces inaccessible. Support for header-only parts was added in mid-2017. Support for Solaris was removed in 2020.)</p>
<p>Some reasons for this include</p>
<ul>
<li><p>Exceptions. Perhaps the largest core issue with adopting the use of Standard Library facilities is exceptions. HotSpot does not use exceptions and, for platforms which allow doing so, builds with them turned off. Many Standard Library facilities implicitly or explicitly use exceptions.</p></li>
<li><p><code>assert</code>. An issue that is quickly encountered is the <code>assert</code> macro name collision (<a href="https://bugs.openjdk.java.net/browse/JDK-8007770">JDK-8007770</a>). Some mechanism for addressing this would be needed before much of the Standard Library could be used. (Not all Standard Library implementations use assert in header files, but some do.)</p></li>
<li><p>Memory allocation. HotSpot requires explicit control over where allocations occur. The C++98/03 <code>std::allocator</code> class is too limited to support our usage. (Changes in more recent Standards may remove this limitation.)</p></li>
<li><p>Implementation vagaries. Bugs, or simply different implementation choices, can lead to different behaviors among the various Standard Libraries we need to deal with.</p></li>
<li><p>Inconsistent naming conventions. HotSpot and the C++ Standard use different naming conventions. The coexistence of those different conventions might appear jarring and reduce readability.</p></li>
</ul>
<p>There are a few exceptions to this rule.</p>
<ul>
<li><code>#include &lt;new&gt;</code> to use placement <code>new</code>, <code>std::nothrow</code>, and <code>std::nothrow_t</code>.</li>
<li><code>#include &lt;limits&gt;</code> to use <code>std::numeric_limits</code>.</li>
<li><code>#include &lt;type_traits&gt;</code>.</li>
<li><code>#include &lt;cstddef&gt;</code> to use <code>std::nullptr_t</code>.</li>
</ul>
<p>TODO: Rather than directly #including (permitted) Standard Library headers, use a convention of #including wrapper headers (in some location like hotspot/shared/stdcpp). This provides a single place for dealing with issues we might have for any given header, esp. platform-specific issues.</p>
<h3 id="type-deduction">Type Deduction</h3>
<p>Use type deduction only if it makes the code clearer or safer. Do not use it merely to avoid the inconvenience of writing an explicit type, unless that type is itself difficult to write. An example of the latter is a function template return type that depends on template parameters in a non-trivial way.</p>
<p>There are several contexts where types are deduced.</p>
<ul>
<li><p>Function argument deduction. This is always permitted, and indeed encouraged. It is nearly always better to allow the type of a function template argument to be deduced rather than explicitly specified.</p></li>
<li><p><code>auto</code> variable declarations (<a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2006/n1984.pdf">n1984</a>)<br> For local variables, this can be used to make the code clearer by eliminating type information that is obvious or irrelevant. Excessive use can make code much harder to understand.</p></li>
<li><p>Function return type deduction (<a href="https://isocpp.org/files/papers/N3638.html">n3638</a>)<br> Only use if the function body has a very small number of <code>return</code> statements, and generally relatively little other code.</p></li>
<li><p>Generic lambdas. Lambdas are not (yet) permitted.</p></li>
<li><p>Lambda init captures. Lambdas are not (yet) permitted.</p></li>
</ul>
<h3 id="expression-sfinae">Expression SFINAE</h3>
<p><a href="https://en.cppreference.com/w/cpp/language/sfinae" title="Substitution Failure Is Not An Error">Substitution Failure Is Not An Error</a> (SFINAE) is a template metaprogramming technique that makes use of template parameter substitution failures to make compile-time decisions.</p>
<p>C++11 relaxed the rules for what constitutes a hard-error when attempting to substitute template parameters with template arguments, making most deduction errors be substitution errors; see (<a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2634.html">n2634</a>). This makes <a href="https://en.cppreference.com/w/cpp/language/sfinae" title="Substitution Failure Is Not An Error">SFINAE</a> more powerful and easier to use. However, the implementation complexity for this change is significant, and this seems to be a place where obscure corner-case bugs in various compilers can be found. So while this feature can (and indeed should) be used (and would be difficult to avoid), caution should be used when pushing to extremes.</p>
<p>Here are a few closely related example bugs:<br> <a href="https://gcc.gnu.org/bugzilla/show_bug.cgi?id=95468" class="uri">https://gcc.gnu.org/bugzilla/show_bug.cgi?id=95468</a><br> <a href="https://developercommunity.visualstudio.com/content/problem/396562/sizeof-deduced-type-is-sometimes-not-a-constant-ex.html" class="uri">https://developercommunity.visualstudio.com/content/problem/396562/sizeof-deduced-type-is-sometimes-not-a-constant-ex.html</a></p>
<h3 id="enum">enum</h3>
<p>Where appropriate, <em>scoped-enums</em> should be used. (<a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2347.pdf">n2347</a>)</p>
<p>Use of <em>unscoped-enums</em> is permitted, though ordinary constants may be preferable when the automatic initializer feature isn't used.</p>
<p>The underlying type (the <em>enum-base</em>) of an unscoped enum type should always be specified explicitly. When unspecified, the underlying type is dependent on the range of the enumerator values and the platform.</p>
<p>The underlying type of a <em>scoped-enum</em> should also be specified explicitly if conversions may be applied to values of that type.</p>
<p>Due to bugs in certain (very old) compilers, there is widespread use of enums and avoidance of in-class initialization of static integral constant members. Compilers having such bugs are no longer supported. Except where an enum is semantically appropriate, new code should use integral constants.</p>
<h3 id="thread_local">thread_local</h3>
<p>Do not use <code>thread_local</code> (<a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2659.htm">n2659</a>); instead, use the HotSpot macro <code>THREAD_LOCAL</code>. The initializer must be a constant expression.</p>
<p>As was discussed in the review for <a href="https://mail.openjdk.java.net/pipermail/hotspot-dev/2019-September/039487.html">JDK-8230877</a>, <code>thread_local</code> allows dynamic initialization and destruction semantics. However, that support requires a run-time penalty for references to non-function-local <code>thread_local</code> variables defined in a different translation unit, even if they don't need dynamic initialization. Dynamic initialization and destruction of namespace-scoped thread local variables also has the same ordering problems as for ordinary namespace-scoped variables.</p>
<h3 id="nullptr">nullptr</h3>
<p>Prefer <code>nullptr</code> (<a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2431.pdf">n2431</a>) to <code>NULL</code>. Don't use (constexpr or literal) 0 for pointers.</p>
<p>For historical reasons there are widespread uses of both <code>NULL</code> and of integer 0 as a pointer value.</p>
<h3 id="atomic">&lt;atomic&gt;</h3>
<p>Do not use facilities provided by the <code>&lt;atomic&gt;</code> header (<a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2427.html">n2427</a>), (<a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2752.htm">n2752</a>); instead, use the HotSpot <code>Atomic</code> class and related facilities.</p>
<p>Atomic operations in HotSpot code must have semantics which are consistent with those provided by the JDK's compilers for Java. There are platform-specific implementation choices that a C++ compiler might make or change that are outside the scope of the C++ Standard, and might differ from what the Java compilers implement.</p>
<p>In addition, HotSpot <code>Atomic</code> has a concept of &quot;conservative&quot; memory ordering, which may differ from (may be stronger than) sequentially consistent. There are algorithms in HotSpot that are believed to rely on that ordering.</p>

<li><p>Inline namespaces (<a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2535.htm">n2535</a>) — HotSpot makes very limited use of namespaces.</p></li>
<li><p><code>using namespace</code> directives. In particular, don't use <code>using namespace std;</code> to avoid needing to qualify Standard Library names.</p></li>
<li><p>Propagating exceptions (<a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2179.html">n2179</a>) — HotSpot does not permit the use of exceptions, so this feature isn't useful.</p></li>
<li><p>Avoid namespace-scoped variables with non-constexpr initialization. In particular, avoid variables with types requiring non-trivial initialization or destruction. Initialization order problems can be difficult to deal with and lead to surprises, as can destruction ordering. HotSpot doesn't generally try to cleanup on exit, and running destructors at exit can also lead to problems.</p></li>
<li><p><code>[[deprecated]]</code> attribute (<a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2013/n3760.html">n3760</a>) — Not relevant in HotSpot code.</p></li>
<li><p>Avoid most operator overloading, preferring named functions. When operator overloading is used, ensure the semantics conform to the normal expected behavior of the operation.</p></li>
<li><p>Avoid most implicit conversion constructors and (implicit or explicit) conversion operators. (Note that conversion to <code>bool</code> isn't needed in HotSpot code because of the &quot;no implicit boolean&quot; guideline.)</p></li>
<li><p>Avoid covariant return types.</p></li>

% HotSpot Coding Style
## Introduction
This is a collection of rules, guidelines, and suggestions for writing
HotSpot code. Following these will help new code fit in with existing
HotSpot code, making it easier to read and maintain. Failure to
follow these guidelines may lead to discussion during code reviews, if
not outright rejection of a change.
### Why Care About Style?
Some programmers seem to have lexers and even C preprocessors
installed directly behind their eyeballs. The rest of us require code
that is not only functionally correct but also easy to read. More than
that, since there is no one style for easy-to-read code, and since a
mashup of many styles is just as confusing as no style at all, it is
important for coders to be conscious of the many implicit stylistic
choices that historically have gone into the HotSpot code base.
Some of these guidelines are driven by the cross-platform requirements
for HotSpot. Shared code must work on a variety of platforms, and may
encounter deficiencies in some. Using platform conditionalization in
shared code is usually avoided, while shared code is strongly
preferred to multiple platform-dependent implementations, so some
language features may be recommended against.
Some of the guidelines here are relatively arbitrary choices among
equally plausible alternatives. The purpose of stating and enforcing
these rules is largely to provide a consistent look to the code. That
consistency makes the code more readable by avoiding non-functional
distractions from the interesting functionality.
When changing pre-existing code, it is reasonable to adjust it to
match these conventions. Exception: If the pre-existing code clearly
conforms locally to its own peculiar conventions, it is not worth
reformatting the whole thing. Also consider separating changes that
make extensive stylistic updates from those which make functional
changes.
### Counterexamples and Updates
Many of the guidelines mentioned here have (sometimes widespread)
counterexamples in the HotSpot code base. Finding a counterexample is
not sufficient justification for new code to follow the counterexample
as a precedent, since readers of your code will rightfully expect your
code to follow the greater bulk of precedents documented here.
Occasionally a guideline mentioned here may be just out of synch with
the actual HotSpot code base. If you find that a guideline is
consistently contradicted by a large number of counterexamples, please
bring it up for discussion and possible change. The architectural
rule, of course, is "When in Rome do as the Romans". Sometimes in the
suburbs of Rome the rules are a little different; these differences
can be pointed out here.
Proposed changes should be discussed on the
[HotSpot Developers](mailto:hotspot-dev@openjdk.java.net) mailing
list, and approved by
[rough consensus](https://en.wikipedia.org/wiki/Rough_consensus) of
the [HotSpot Group](https://openjdk.java.net/census#hotspot) Members.
The Group Lead determines whether consensus has been reached.
Changes are likely to be cautious and incremental, since HotSpot
coders have been using these guidelines for years.
## Structure and Formatting
### Factoring and Class Design
* Group related code together, so readers can concentrate on one
section of one file.
* Classes are the primary code structuring mechanism. Place related
functionality in a class, or a set of related classes. Use of either
namespaces or public non-member functions is rare in HotSpot code.
Static non-member functions are not uncommon.
* If a class `FooBar` is going to be used in more than one place, put it
a file named fooBar.hpp and fooBar.cpp. If the class is a sidekick
to a more important class `BazBat`, it can go in bazBat.hpp.
* Put a member function `FooBar::bang` into the same file that defined
`FooBar`, or its associated *.inline.hpp or *.cpp file.
* Use public accessor functions for member variables accessed
outside the class.
* Assign names to constant literals and use the names instead.
* Keep functions small, a screenful at most. Split out chunks of
logic into file-local classes or static functions if needed.
* Factor away nonessential complexity into local inline helper
functions and helper classes.
* Think clearly about internal invariants that apply to each class,
and document them in the form of asserts within member functions.
* Make simple, self-evident contracts for member functions. If you cannot
communicate a simple contract, redesign the class.
* Implement classes as if expecting rough usage by clients. Check for
incorrect usage of a class using `assert(...)`, `guarantee(...)`,
`ShouldNotReachHere()` and comments wherever needed. Performance is
almost never a reason to omit asserts.
* When possible, design as if for reusability. This forces a clear
design of the class's externals, and clean hiding of its internals.
* Initialize all variables and data structures to a known state. If a
class has a constructor, initialize it there.
* Do no optimization before its time. Prove the need to optimize.
* When you must defactor to optimize, preserve as much structure as
possible. If you must hand-inline some name, label the local copy with
the original name.
* If you need to use a hidden detail (e.g., a structure offset), name
it (as a constant or function) in the class that owns it.
* Don't use the Copy and Paste keys to replicate more than a couple
lines of code. Name what you must repeat.
* If a class needs a member function to change a user-visible attribute, the
change should be done with a "setter" accessor matched to the simple
"getter".
### Source Files
* All source files must have a globally unique basename. The build
system depends on this uniqueness.
* Do not put non-trivial function implementations in .hpp files. If
the implementation depends on other .hpp files, put it in a .cpp or
a .inline.hpp file.
* .inline.hpp files should only be included in .cpp or .inline.hpp
files.
* All .cpp files include precompiled.hpp as the first include line.
* precompiled.hpp is just a build time optimization, so don't rely on
it to resolve include problems.
* Keep the include lines alphabetically sorted.
* Put conditional inclusions (`#if ...`) at the end of the include list.
### JTReg Tests
* JTReg tests should have meaningful names.
* JTReg tests associated with specific bugs should be tagged with the
`@bug` keyword in the test description.
* JTReg tests should be organized by component or feature under
`test/`, in a directory hierarchy that generally follows that of the
`src/` directory. There may be additional subdirectories to further
categorize tests by feature. This structure makes it easy to run a
collection of tests associated with a specific feature by specifying
the associated directory as the source of the tests to run.
* Some (older) tests use the associated bug number in the directory
name, the test name, or both. That naming style should no longer be
used, with existing tests using that style being candidates for migration.
### Naming
* The length of a name may be correlated to the size of its scope. In
particular, short names (even single letter names) may be fine in a
small scope, but are usually inappropriate for larger scopes.
* Prefer whole words rather than abbreviations, unless the
abbreviation is more widely used than the long form in the code's
domain.
* Choose names consistently. Do not introduce spurious
variations. Abbreviate corresponding terms to a consistent length.
* Global names must be unique, to avoid [One Definition Rule][ODR] (ODR)
violations. A common prefixing scheme for related global names is
often used. (This is instead of using namespaces, which are mostly
avoided in HotSpot.)
* Don't give two names to the semantically same thing. But use
different names for semantically different things, even if they are
representationally the same. (So use meaningful `typedef` or template
alias names where appropriate.)
* When choosing names, avoid categorical nouns like "variable",
"field", "parameter", "value", and verbs like "compute", "get".
(`storeValue(int param)` is bad.)
* Type names and global names should use mixed-case with the first
letter of each word capitalized (`FooBar`).
* Embedded abbreviations in
otherwise mixed-case names are usually capitalized entirely rather
than being treated as a single word with only the initial letter
capitalized, e.g. "HTML" rather than "Html".
* Function and local variable names use lowercase with words separated
by a single underscore (`foo_bar`).
* Class data member names have a leading underscore, and use lowercase
with words separated by a single underscore (`_foo_bar`).
* Constant names may be upper-case or mixed-case, according to
historical necessity. (Note: There are many examples of constants
with lowercase names.)
* Constant names should follow an existing pattern, and must have a
distinct appearance from other names in related APIs.
* Class and type names should be noun phrases. Consider an "er" suffix
for a class that represents an action.
* Function names should be verb phrases that reflect changes of state
known to a class's user, or else noun phrases if they cause no change
of state visible to the class's user.
* Getter accessor names are noun phrases, with no "`get_`" noise
word. Boolean getters can also begin with "`is_`" or "`has_`". Member
function for reading data members usually have the same name as the
data member, exclusive of the leading underscore.
* Setter accessor names prepend "`set_`" to the getter name.
* Other member function names are verb phrases, as if commands to the receiver.
* Avoid leading underscores (as "`_oop`") except in cases required
above. (Names with leading underscores can cause portability
problems.)
### Commenting
* Clearly comment subtle fixes.
* Clearly comment tricky classes and functions.
* If you have to choose between commenting code and writing wiki
content, comment the code. Link from the wiki to the source file if
it makes sense.
* As a general rule don't add bug numbers to comments (they would soon
overwhelm the code). But if the bug report contains significant
information that can't reasonably be added as a comment, then refer to
the bug report.
* Personal names are discouraged in the source code, which is a team
product.
### Macros
* You can almost always use an inline function or class instead of a
macro. Use a macro only when you really need it.
* Templates may be preferable to multi-line macros. (There may be
subtle performance effects with templates on some platforms; revert
to macros if absolutely necessary.)
* `#ifdef`s should not be used to introduce platform-specific code
into shared code (except for `_LP64`). They must be used to manage
header files, in the pattern found at the top of every source
file. They should be used mainly for major build features, including
`PRODUCT`, `ASSERT`, `_LP64`, `INCLUDE_SERIALGC`, `COMPILER1`, etc.
* For build features such as `PRODUCT`, use `#ifdef PRODUCT` for
multiple-line inclusions or exclusions.
* For short inclusions or exclusions based on build features, use
macros like `PRODUCT_ONLY` and `NOT_PRODUCT`. But avoid using them
with multiple-line arguments, since debuggers do not handle that
well.
* Use `CATCH`, `THROW`, etc. for HotSpot-specific exception processing.
### Whitespace
* In general, don't change whitespace unless it improves readability
or consistency. Gratuitous whitespace changes will make integrations
and backports more difficult.
* Use One-True-Brace-Style. The opening brace for a function or class
is normally at the end of the line; it is sometimes moved to the
beginning of the next line for emphasis. Substatements are enclosed
in braces, even if there is only a single statement. Extremely simple
one-line statements may drop braces around a substatement.
* Indentation levels are two columns.
* There is no hard line length limit. That said, bear in mind that
excessively long lines can cause difficulties. Some people like to
have multiple side-by-side windows in their editors, and long lines
may force them to choose among unpleasant options. They can use wide
windows, reducing the number that can fit across the screen, and
wasting a lot of screen real estate because most lines are not that
long. Alternatively, they can have more windows across the screen,
with long lines wrapping (or worse, requiring scrolling to see in
their entirety), which is harder to read. Similar issues exist for
side-by-side code reviews.
* Tabs are not allowed in code. Set your editor accordingly.<br>
(Emacs: `(setq-default indent-tabs-mode nil)`.)
* Use good taste to break lines and align corresponding tokens on
adjacent lines.
* Use spaces around operators, especially comparisons and
assignments. (Relaxable for boolean expressions and high-precedence
operators in classic math-style formulas.)
* Put spaces on both sides of control flow keywords `if`, `else`,
`for`, `switch`, etc. Don't add spaces around the associated
_control_ expressions. Examples:
```
while (test_foo(args...)) { // Yes
while(test_foo(args...)) { // No, missing space after while
while ( test_foo(args...) ) { // No, excess spaces around control
```
* Use extra parentheses in expressions whenever operator precedence
seems doubtful. Always use parentheses in shift/mask expressions
(`<<`, `&`, `|`). Don't add whitespace immediately inside
parentheses.
* Use more spaces and blank lines between larger constructs, such as
classes or function definitions.
* If the surrounding code has any sort of vertical organization,
adjust new lines horizontally to be consistent with that
organization. (E.g., trailing backslashes on long macro definitions
often align.)
### Miscellaneous
* Use the [Resource Acquisition Is Initialization][RAII] (RAII)
design pattern to manage bracketed critical
sections. See class `ResourceMark` for an example.
* Avoid implicit conversions to `bool`.
* Use `bool` for boolean values.
* Do not use ints or pointers as (implicit) booleans with `&&`, `||`,
`if`, `while`. Instead, compare explicitly, i.e. `if (x != 0)` or
`if (ptr != nullptr)`, etc.
* Do not use declarations in _condition_ forms, i.e. don't use
`if (T v = value) { ... }`.
* Use functions from globalDefinitions.hpp and related files when
performing bitwise
operations on integers. Do not code directly as C operators, unless
they are extremely simple. (Examples: `align_up`, `is_power_of_2`,
`exact_log2`.)
* Use arrays with abstractions supporting range checks.
* Always enumerate all cases in a switch statement or provide a default
case. It is ok to have an empty default with comment.
## Use of C++ Features
HotSpot was originally written in a subset of the C++98/03 language.
More recently, support for C++14 is provided, though again,
HotSpot only uses a subset. (Backports to JDK versions lacking
support for more recent Standards must of course stick with the
original C++98/03 subset.)
This section describes that subset. Features from the C++98/03
language may be used unless explicitly excluded here. Features from
C++11 and C++14 may be explicitly permitted or explicitly excluded,
and discussed accordingly here. There is a third category, undecided
features, about which HotSpot developers have not yet reached a
consensus, or perhaps have not discussed at all. Use of these
features is also excluded.
(The use of some features may not be immediately obvious and may slip
in anyway, since the compiler will accept them. The code review
process is the main defense against this.)
Some features are discussed in their own subsection, typically to provide
more extensive discussion or rationale for limitations. Features that
don't have their own subsection are listed in omnibus feature sections
for permitted, excluded, and undecided features.
Lists of new features for C++11 and C++14, along with links to their
descriptions, can be found in the online documentation for some of the
compilers and libraries. The C++14 Standard is the definitive
description.
* [C++ Standards Support in GCC](https://gcc.gnu.org/projects/cxx-status.html)
* [C++ Support in Clang](https://clang.llvm.org/cxx_status.html)
* [Visual C++ Language Conformance](https://docs.microsoft.com/en-us/cpp/visual-cpp-language-conformance)
* [libstdc++ Status](https://gcc.gnu.org/onlinedocs/libstdc++/manual/status.html)
* [libc++ Status](https://libcxx.llvm.org/cxx1y_status.html)
As a rule of thumb, permitting features which simplify writing code
and, especially, reading code, is encouraged.

### Error Handling
Do not use exceptions. Exceptions are disabled by the build configuration
for some platforms.
Rationale: There is significant concern over the performance cost of
exceptions and their usage model and implications for maintainable code.
That's not just a matter of history that has been fixed; there remain
questions and problems even today (2019). See, for example, [Zero cost
deterministic
exceptions](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p0709r0.pdf).
Because of this, HotSpot has always used a build configuration that disables
exceptions where that is available. As a result, HotSpot code uses error
handling mechanisms such as two-phase construction, factory functions,
returning error codes, and immediate termination. Even if the cost of
exceptions were not a concern, the existing body of code was not written with
exception safety in mind. Making HotSpot exception safe would be a very large
undertaking.
In addition to the usual alternatives to exceptions, HotSpot provides its
own exception mechanism. This is based on a set of macros defined in
utilities/exceptions.hpp.
### RTTI (Runtime Type Information)
Do not use [Runtime Type Information][RTTI] (RTTI).
[RTTI][] is disabled by the build configuration for some
platforms. Among other things, this means `dynamic_cast` cannot be used.
Rationale: Other than to implement exceptions (which HotSpot doesn't use),
most potential uses of [RTTI][] are better done via virtual functions. Some of
the remainder can be replaced by bespoke mechanisms. The cost of the
additional runtime data structures needed to support [RTTI][] are deemed not
worthwhile, given the alternatives.
### Memory Allocation
Do not use the standard global allocation and deallocation functions
(operator new and related functions). Use of these functions by HotSpot
code is disabled for some platforms.
Rationale: HotSpot often uses "resource" or "arena" allocation. Even
where heap allocation is used, the standard global functions are
avoided in favor of wrappers around malloc and free that support the
VM's Native Memory Tracking (NMT) feature.
Native memory allocation failures are often treated as non-recoverable.
The place where "out of memory" is (first) detected may be an innocent
bystander, unrelated to the actual culprit.
### Class Inheritance
Use public single inheritance.
Prefer composition rather than non-public inheritance.
Restrict inheritance to the "is-a" case; use composition rather than
non-is-a related inheritance.
Avoid multiple inheritance. Never use virtual inheritance.
### Namespaces
Avoid using namespaces. HotSpot code normally uses "all static"
classes rather than namespaces for grouping. An "all static" class is
not instantiable, has only static members, and is normally derived
(possibly indirectly) from the helper class `AllStatic`.
Benefits of using such classes include:
* Provides access control for members, which is unavailable with
namespaces.
* Avoids [Argument Dependent Lookup][ADL] (ADL).
* Closed for additional members. Namespaces allow names to be added in
multiple contexts, making it harder to see the complete API.
Namespaces should be used only in cases where one of those "benefits"
is actually a hindrance.
In particular, don't use anonymous namespaces. They seem like they should
be useful, and indeed have some real benefits for naming and generated code
size on some platforms. Unfortunately, debuggers don't seem to like them at
all.
<https://groups.google.com/forum/#!topic/mozilla.dev.platform/KsaG3lEEaRM><br>
Suggests Visual Studio debugger might not be able to refer to
anonymous namespace symbols, so can't set breakpoints in them.
Though the discussion seems to go back and forth on that.
<https://firefox-source-docs.mozilla.org/code-quality/coding-style/coding_style_cpp.html><br>
Search for "Anonymous namespaces"
Suggests preferring "static" to anonymous namespaces where applicable,
because of poor debugger support for anonymous namespaces.
<https://sourceware.org/bugzilla/show_bug.cgi?id=16874><br>
Bug for similar gdb problems.
### C++ Standard Library
Avoid using the C++ Standard Library.
Historically, HotSpot has mostly avoided use of the Standard
Library.
(It used to be impossible to use most of it in shared code,
because the build configuration for Solaris with Solaris Studio made
all but a couple of pieces inaccessible. Support for header-only
parts was added in mid-2017. Support for Solaris was removed
in 2020.)
Some reasons for this include
* Exceptions. Perhaps the largest core issue with adopting the use of
Standard Library facilities is exceptions. HotSpot does not use
exceptions and, for platforms which allow doing so, builds with them
turned off. Many Standard Library facilities implicitly or explicitly
use exceptions.
* `assert`. An issue that is quickly encountered is the `assert` macro name
collision ([JDK-8007770](https://bugs.openjdk.java.net/browse/JDK-8007770)).
Some mechanism for addressing this would be needed before much of the
Standard Library could be used. (Not all Standard Library implementations
use assert in header files, but some do.)
* Memory allocation. HotSpot requires explicit control over where
allocations occur. The C++98/03 `std::allocator` class is too limited
to support our usage. (Changes in more recent Standards may remove
this limitation.)
* Implementation vagaries. Bugs, or simply different implementation choices,
can lead to different behaviors among the various Standard Libraries we need
to deal with.
* Inconsistent naming conventions. HotSpot and the C++ Standard use
different naming conventions. The coexistence of those different conventions
might appear jarring and reduce readability.
There are a few exceptions to this rule.
* `#include <new>` to use placement `new`, `std::nothrow`, and `std::nothrow_t`.
* `#include <limits>` to use `std::numeric_limits`.
* `#include <type_traits>`.
* `#include <cstddef>` to use `std::nullptr_t`.
TODO: Rather than directly \#including (permitted) Standard Library
headers, use a convention of \#including wrapper headers (in some
location like hotspot/shared/stdcpp). This provides a single place
for dealing with issues we might have for any given header, esp.
platform-specific issues.
### Type Deduction
Use type deduction only if it makes the code clearer or safer. Do not
use it merely to avoid the inconvenience of writing an explicit type,
unless that type is itself difficult to write. An example of the
latter is a function template return type that depends on template
parameters in a non-trivial way.
There are several contexts where types are deduced.
* Function argument deduction. This is always permitted, and indeed
encouraged. It is nearly always better to allow the type of a
function template argument to be deduced rather than explicitly
specified.
* `auto` variable declarations
([n1984](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2006/n1984.pdf))<br>
For local variables, this can be used to make the code clearer by
eliminating type information that is obvious or irrelevant. Excessive
use can make code much harder to understand.
* Function return type deduction
([n3638](https://isocpp.org/files/papers/N3638.html))<br>
Only use if the function body has a very small number of `return`
statements, and generally relatively little other code.
* Generic lambdas. Lambdas are not (yet) permitted.
* Lambda init captures. Lambdas are not (yet) permitted.
### Expression SFINAE
[Substitution Failure Is Not An Error][SFINAE] (SFINAE)
is a template metaprogramming technique that makes use of
template parameter substitution failures to make compile-time decisions.
C++11 relaxed the rules for what constitutes a hard-error when
attempting to substitute template parameters with template arguments,
making most deduction errors be substitution errors; see
([n2634](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2634.html)).
This makes [SFINAE][] more powerful and easier to use. However, the
implementation complexity for this change is significant, and this
seems to be a place where obscure corner-case bugs in various
compilers can be found. So while this feature can (and indeed should)
be used (and would be difficult to avoid), caution should be used when
pushing to extremes.
Here are a few closely related example bugs:<br>
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=95468><br>
<https://developercommunity.visualstudio.com/content/problem/396562/sizeof-deduced-type-is-sometimes-not-a-constant-ex.html>
### enum
Where appropriate, _scoped-enums_ should be used.
([n2347](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2347.pdf))
Use of _unscoped-enums_ is permitted, though ordinary constants may be
preferable when the automatic initializer feature isn't used.
The underlying type (the _enum-base_) of an unscoped enum type should
always be specified explicitly. When unspecified, the underlying type
is dependent on the range of the enumerator values and the platform.
The underlying type of a _scoped-enum_ should also be specified
explicitly if conversions may be applied to values of that type.
Due to bugs in certain (very old) compilers, there is widespread use
of enums and avoidance of in-class initialization of static integral
constant members. Compilers having such bugs are no longer supported.
Except where an enum is semantically appropriate, new code should use
integral constants.
### thread_local
Do not use `thread_local`
([n2659](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2659.htm));
instead, use the HotSpot macro `THREAD_LOCAL`. The initializer must
be a constant expression.
As was discussed in the review for
[JDK-8230877](https://mail.openjdk.java.net/pipermail/hotspot-dev/2019-September/039487.html),
`thread_local` allows dynamic initialization and destruction
semantics. However, that support requires a run-time penalty for
references to non-function-local `thread_local` variables defined in a
different translation unit, even if they don't need dynamic
initialization. Dynamic initialization and destruction of
namespace-scoped thread local variables also has the same ordering
problems as for ordinary namespace-scoped variables.
### nullptr
Prefer `nullptr`
([n2431](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2431.pdf))
to `NULL`. Don't use (constexpr or literal) 0 for pointers.
For historical reasons there are widespread uses of both `NULL` and of
integer 0 as a pointer value.
### &lt;atomic&gt;
Do not use facilities provided by the `<atomic>` header
([n2427](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2427.html)),
([n2752](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2752.htm));
instead, use the HotSpot `Atomic` class and related facilities.
Atomic operations in HotSpot code must have semantics which are
consistent with those provided by the JDK's compilers for Java. There
are platform-specific implementation choices that a C++ compiler might
make or change that are outside the scope of the C++ Standard, and
might differ from what the Java compilers implement.
In addition, HotSpot `Atomic` has a concept of "conservative" memory
ordering, which may differ from (may be stronger than) sequentially
consistent. There are algorithms in HotSpot that are believed to rely
on that ordering.
### Additional Permitted Features
* `constexpr`
([n2235](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2235.pdf))
([n3652](https://isocpp.org/files/papers/N3652.html))
* Sized deallocation
([n3778](https://isocpp.org/files/papers/n3778.html))
* Variadic templates
([n2242](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2242.pdf))
([n2555](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2555.pdf))
* Static assertions
([n1720](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2004/n1720.html))
* `decltype`
([n2343](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2343.pdf))
([n3276](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2011/n3276.pdf))
* Right angle brackets
([n1757](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2005/n1757.html))
* Default template arguments for function templates
([CWG D226](http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#226))
* Template aliases
([n2258](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2258.pdf))
* Delegating constructors
([n1986](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2006/n1986.pdf))
* Explicit conversion operators
([n2437](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2437.pdf))
* Standard Layout Types
([n2342](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2342.htm))

([n2928](http://www.open-std.org/JTC1/SC22/WG21/docs/papers/2009/n2928.htm)),
([n3206](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2010/n3206.htm)),

* Local and unnamed types as template parameters
([n2657](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2657.htm))
### Excluded Features
* New string and character literals
* New character types
([n2249](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2249.html))
* Unicode string literals
([n2442](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2442.htm))
* Raw string literals
([n2442](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2442.htm))
* Universal character name literals
([n2170](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2170.html))
HotSpot doesn't need any of the new character and string literal
types.
* User-defined literals
([n2765](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2765.pdf)) &mdash;
User-defined literals should not be added casually, but only
through a proposal to add a specific UDL.
* Inline namespaces
([n2535](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2535.htm)) &mdash;
HotSpot makes very limited use of namespaces.
* `using namespace` directives. In particular, don't use `using
namespace std;` to avoid needing to qualify Standard Library names.
* Propagating exceptions
([n2179](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2179.html)) &mdash;
HotSpot does not permit the use of exceptions, so this feature isn't useful.
* Avoid namespace-scoped variables with non-constexpr initialization.
In particular, avoid variables with types requiring non-trivial
initialization or destruction. Initialization order problems can be
difficult to deal with and lead to surprises, as can destruction
ordering. HotSpot doesn't generally try to cleanup on exit, and
running destructors at exit can also lead to problems.
* `[[deprecated]]` attribute
([n3760](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2013/n3760.html)) &mdash;
Not relevant in HotSpot code.
* Avoid most operator overloading, preferring named functions. When
operator overloading is used, ensure the semantics conform to the
normal expected behavior of the operation.
* Avoid most implicit conversion constructors and (implicit or explicit)
conversion operators. (Note that conversion to `bool` isn't needed
in HotSpot code because of the "no implicit boolean" guideline.)
* Avoid covariant return types.
* Avoid `goto` statements.
### Undecided Features
This list is incomplete; it serves to explicitly call out some
features that have not yet been discussed.
* `overrides` virtual specifiers for virtual functions
([n3272](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2011/n3272.htm))
* Trailing return type syntax for functions
([n2541](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2541.htm))
* Variable templates
([n3651](https://isocpp.org/files/papers/N3651.pdf))
* Member initializers and aggregates
([n3653](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2013/n3653.html))
* `[[noreturn]]` attribute
([n2761](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2761.pdf))
* Rvalue references and move semantics
* Lambdas

<p>The purpose of these guidelines is to establish a shared vision on what kind of native tests and how we want to develop them for Hotspot using GoogleTest. Hence these guidelines include style items as well as test approach items.</p>
<p>First section of this document describes properties of good tests which are common for almost all types of test regardless of language, framework, etc. Further sections provide recommendations to achieve those properties and other HotSpot and/or GoogleTest specific guidelines.</p>
<h2 id="good-test-properties">Good test properties</h2>
<h3 id="lightness">Lightness</h3>
<p>Use the most lightweight type of tests.</p>
<p>In Hotspot, there are 3 different types of tests regarding their dependency on a JVM, each next level is slower than previous</p>
<ul>
<li><p><code>TEST</code> : a test does not depend on a JVM</p></li>
<li><p><code>TEST_VM</code> : a test does depend on an initialized JVM, but are supposed not to break a JVM, i.e. leave it in a workable state.</p></li>
<li><p><code>TEST_OTHER_VM</code> : a test depends on a JVM and requires a freshly initialized JVM or leaves a JVM in non-workable state</p></li>
</ul>
<h3 id="isolation">Isolation</h3>
<p>Tests have to be isolated: not to have visible side-effects, influences on other tests results.</p>
<p>Results of one test should not depend on test execution order, other tests, otherwise it is becoming almost impossible to find out why a test failed. Due to hotspot-specific, it is not so easy to get a full isolation, e.g. we share an initialized JVM between all <code>TEST_VM</code> tests, so if your test changes JVM's state too drastically and does not change it back, you had better consider <code>TEST_OTHER_VM</code>.</p>
<h3 id="atomicity-and-self-containment">Atomicity and self-containment</h3>
<p>Tests should be <em>atomic</em> and <em>self-contained</em> at the same time.</p>
<p>One test should check a particular part of a class, subsystem, functionality, etc. Then it is quite easy to determine what parts of a product are broken basing on test failures. On the other hand, a test should test that part more-or-less entirely, because when one sees a test <code>FooTest::bar</code>, they assume all aspects of bar from <code>Foo</code> are tested.</p>
<p>However, it is impossible to cover all aspects even of a method, not to mention a subsystem. In such cases, it is recommended to have several tests, one for each aspect of a thing under test. For example one test to tests how <code>Foo::bar</code> works if an argument is <code>null</code>, another test to test how it works if an argument is acceptable but <code>Foo</code> is not in the right state to accept it and so on. This helps not only to make tests atomic, self-contained but also makes test name self-descriptive (discussed in more details in <a href="#test-names">Test names</a>).</p>
<h3 id="repeatability">Repeatability</h3>
<p>Tests have to be repeatable.</p>
<p>Reproducibility is very crucial for a test. No one likes sporadic test failures, they are hard to investigate, fix and verify a fix.</p>
<p>In some cases, it is quite hard to write a 100% repeatable test, since besides a test there can be other moving parts, e.g. in case of <code>TEST_VM</code> there are several concurrently running threads. Despite this, we should try to make a test as reproducible as possible.</p>
<h3 id="informativeness">Informativeness</h3>
<p>In case of a failure, a test should be as <em>informative</em> as possible.</p>
<p>Having more information about a test failure than just compared values can be very useful for failure troubleshooting, it can reduce or even completely eliminate debugging hours. This is even more important in case of not 100% reproducible failures.</p>
<p>Achieving this property, one can easily make a test too verbose, so it will be really hard to find useful information in the ocean of useless information. Hence they should not only think about how to provide <a href="#error-messages">good information</a>, but also <a href="#uncluttered-output">when to do it</a>.</p>
<h3 id="testing-instead-of-visiting">Testing instead of visiting</h3>
<p>Tests should <em>test</em>.</p>
<p>It is not enough just to &quot;visit&quot; some code, a test should check that code does that it has to do, compare return values with expected values, check that desired side effects are done, and undesired are not, and so on. In other words, a test should contain at least one GoogleTest assertion and do not rely on JVM asserts.</p>
<p>Generally speaking to write a good test, one should create a model of the system under tests, a model of possible bugs (or bugs which one wants to find) and design tests using those models.</p>
<h3 id="nearness">Nearness</h3>
<p>Prefer having checks inside test code.</p>
<p>Not only does having test logic outside, e.g. verification method, depending on asserts in product code contradict with several items above but also decreases tests readability and stability. It is much easier to understand that a test is testing when all testing logic is located inside a test or nearby in shared test libraries. As a rule of thumb, the closer a check to a test, the better.</p>
<h2 id="asserts">Asserts</h2>
<h3 id="several-checks">Several checks</h3>
<p>Prefer <code>EXPECT</code> over <code>ASSERT</code> if possible.</p>
<p>This is related to the <a href="#informativeness">informativeness</a> property of tests, information for other checks can help to better localize a defects root-cause. One should use <code>ASSERT</code> if it is impossible to continue test execution or if it does not make much sense. Later in the text, <code>EXPECT</code> forms will be used to refer to both <code>ASSERT/EXPECT</code>.</p>
<p>When it is possible to make several different checks, but impossible to continue test execution if at least one check fails, you can use <code>::testing::Test::HasNonfatalFailure()</code> function. The recommended way to express that is <code>ASSERT_FALSE(::testing::Test::HasNonfatalFailure())</code>. Besides making it clear why a test is aborted, it also allows you to provide more information about a failure.</p>
<h3 id="first-parameter-is-expected-value">First parameter is expected value</h3>
<p>In all equality assertions, expected values should be passed as the first parameter.</p>
<p>This convention is adopted by GoogleTest, and there is a slight difference in how GoogleTest treats parameters, the most important one is <code>null</code> detection. Due to different reasons, <code>null</code> detection is enabled only for the first parameter, that is to said <code>EXPECT_EQ(NULL, object)</code> checks that object is <code>null</code>, while <code>EXPECT_EQ(object, NULL)</code> checks that object equals to <code>NULL</code>, GoogleTest is very strict regarding types of compared values so the latter will generates a compile-time error.</p>
<h3 id="floating-point-comparison">Floating-point comparison</h3>
<p>Use floating-point special macros to compare <code>float/double</code> values.</p>
<p>Because of floating-point number representations and round-off errors, regular equality comparison will not return true in most cases. There are special <code>EXPECT_FLOAT_EQ/EXPECT_DOUBLE_EQ</code> assertions which check that the distance between compared values is not more than 4 ULPs, there is also <code>EXPECT_NEAR(v1, v2, eps)</code> which checks that the absolute value of the difference between <code>v1</code> and <code>v2</code> is not greater than <code>eps</code>.</p>
<h3 id="c-string-comparison">C string comparison</h3>
<p>Use string special macros for C strings comparisons.</p>
<p><code>EXPECT_EQ</code> just compares pointers values, which is hardly what one wants comparing C strings. GoogleTest provides <code>EXPECT_STREQ</code> and <code>EXPECT_STRNE</code> macros to compare C string contents. There are also case-insensitive versions <code>EXPECT_STRCASEEQ</code>, <code>EXPECT_STRCASENE</code>.</p>
<h3 id="error-messages">Error messages</h3>
<p>Provide informative, but not too verbose error messages.</p>
<p>All GoogleTest asserts print compared expressions and their values, so there is no need to have them in error messages. Asserts print only compared values, they do not print any of interim variables, e.g. <code>ASSERT_TRUE((val1 == val2 &amp;&amp; isFail(foo(8)) || i == 18)</code> prints only one value. If you use some complex predicates, please consider <code>EXPECT_PRED*</code> or <code>EXPECT_FORMAT_PRED</code> assertions family, they check that a predicate returns true/success and print out all parameters values.</p>
<p>However in some cases, default information is not enough, a commonly used example is an assert inside a loop, GoogleTest will not print iteration values (unless it is an assert's parameter). Other demonstrative examples are printing error code and a corresponding error message; printing internal states which might have an impact on results. One should add this information to assert message using <code>&lt;&lt;</code> operator.</p>
<h3 id="uncluttered-output">Uncluttered output</h3>
<p>Print information only if it is needed.</p>
<p>Too verbose tests which print all information even if they pass are very bad practice. They just pollute output, so it becomes harder to find useful information. In order not print information till it is really needed, one should consider saving it to a temporary buffer and pass to an assert. <a href="https://hg.openjdk.java.net/jdk/jdk/file/tip/test/hotspot/gtest/gc/shared/test_memset_with_concurrent_readers.cpp" class="uri">https://hg.openjdk.java.net/jdk/jdk/file/tip/test/hotspot/gtest/gc/shared/test_memset_with_concurrent_readers.cpp</a> has a good example how to do that.</p>
<h3 id="failures-propagation">Failures propagation</h3>
<p>Wrap a subroutine call into <code>EXPECT_NO_FATAL_FAILURE</code> macro to propagate failures.</p>
<p><code>ASSERT</code> and <code>FAIL</code> abort only the current function, so if you have them in a subroutine, a test will not be aborted after the subroutine even if <code>ASSERT</code> or <code>FAIL</code> fails. You should call such subroutines in <code>ASSERT_NO_FATAL_FAILURE</code> macro to propagate fatal failures and abort a test. <code>(EXPECT|ASSERT)_NO_FATAL_FAILURE</code> can also be used to provide more information.</p>
<p>Due to obvious reasons, there are no <code>(EXPECT|ASSERT)_NO_NONFATAL_FAILURE</code> macros. However, if you need to check if a subroutine generated a nonfatal failure (failed an <code>EXPECT</code>), you can use <code>::testing::Test::HasNonfatalFailure</code> function, or <code>::testing::Test::HasFailure</code> function to check if a subroutine generated any failures, see <a href="#several-checks">Several checks</a>.</p>
<h2 id="naming-and-grouping">Naming and Grouping</h2>
<h3 id="test-group-names">Test group names</h3>
<p>Test group names should be in CamelCase, start and end with a letter. A test group should be named after tested class, functionality, subsystem, etc.</p>
<p>This naming scheme helps to find tests, filter them and simplifies test failure analysis. For example, class <code>Foo</code> - test group <code>Foo</code>, compiler logging subsystem - test group <code>CompilerLogging</code>, G1 GC — test group <code>G1GC</code>, and so forth.</p>
<h3 id="filename">Filename</h3>
<p>A test file must have <code>test_</code> prefix and <code>.cpp</code> suffix.</p>
<p>Both are actually requirements from the current build system to recognize your tests.</p>
<h3 id="file-location">File location</h3>
<p>Test file location should reflect a location of the tested part of the product.</p>
<ul>
<li><p>All unit tests for a class from <code>foo/bar/baz.cpp</code> should be placed <code>foo/bar/test_baz.cpp</code> in <code>hotspot/test/native/</code> directory. Having all tests for a class in one file is a common practice for unit tests, it helps to see all existing tests at once, share functions and/or resources without losing encapsulation.</p></li>
<li><p>For tests which test more than one class, directory hierarchy should be the same as product hierarchy, and file name should reflect the name of the tested subsystem/functionality. For example, if a sub-system under tests belongs to <code>gc/g1</code>, tests should be placed in <code>gc/g1</code> directory.</p></li>
</ul>
<p>Please note that framework prepends directory name to a test group name. For example, if <code>TEST(foo, check_this)</code> and <code>TEST(bar, check_that)</code> are defined in <code>hotspot/test/native/gc/shared/test_foo.cpp</code> file, they will be reported as <code>gc/shared/foo::check_this</code> and <code>gc/shared/bar::check_that</code>.</p>
<h3 id="test-names">Test names</h3>
<p>Test names should be in small_snake_case, start and end with a letter. A test name should reflect that a test checks.</p>
<p>Such naming makes tests self-descriptive and helps a lot during the whole test life cycle. It is easy to do test planning, test inventory, to see what things are not tested, to review tests, to analyze test failures, to evolve a test, etc. For example <code>foo_return_0_if_name_is_null</code> is better than <code>foo_sanity</code> or <code>foo_basic</code> or just <code>foo</code>, <code>humongous_objects_can_not_be_moved_by_young_gc</code> is better than <code>ho_young_gc</code>.</p>
<p>Actually using underscore is against GoogleTest project convention, because it can lead to illegal identifiers, however, this is too strict. Restricting usage of underscore for test names only and prohibiting test name starts or ends with an underscore are enough to be safe.</p>
<h3 id="fixture-classes">Fixture classes</h3>
<p>Fixture classes should be named after tested classes, subsystems, etc (follow <a href="#test-group-names">Test group names rule</a>) and have <code>Test</code> suffix to prevent class name conflicts.</p>
<h3 id="friend-classes">Friend classes</h3>
<p>All test purpose friends should have either <code>Test</code> or <code>Testable</code> suffix.</p>
<p>It greatly simplifies understanding of friendships purpose and allows statically check that private members are not exposed unexpectedly. Having <code>FooTest</code> as a friend of <code>Foo</code> without any comments will be understood as a necessary evil to get testability.</p>
<h3 id="oscpu-specific-tests">OS/CPU specific tests</h3>
<p>Guard OS/CPU specific tests by <code>#ifdef</code> and have OS/CPU name in filename.</p>
<p>For the time being, we do not support separate directories for OS, CPU, OS-CPU specific tests, in case we will have lots of such tests, we will change directory layout and build system to support that in the same way it is done in hotspot.</p>
<h2 id="miscellaneous">Miscellaneous</h2>
<h3 id="hotspot-style">Hotspot style</h3>
<p>Abide the norms and rules accepted in Hotspot style guide.</p>
<p>Tests are a part of Hotspot, so everything (if applicable) we use for Hotspot, should be used for tests as well. Those guidelines cover test-specific things.</p>
<h3 id="codetest-metrics">Code/test metrics</h3>
<p>Coverage information and other code/test metrics are quite useful to decide what tests should be written, what tests should be improved and what can be removed.</p>
<p>For unit tests, widely used and well-known coverage metric is branch coverage, which provides good quality of tests with relatively easy test development process. For other levels of testing, branch coverage is not as good, and one should consider others metrics, e.g. transaction flow coverage, data flow coverage.</p>
<h3 id="access-to-non-public-members">Access to non-public members</h3>
<p>Use explicit friend class to get access to non-public members.</p>
<p>We do not use GoogleTest macro to declare friendship relation, because, from our point of view, it is less clear than an explicit declaration.</p>
<p>Declaring a test fixture class as a friend class of a tested test is the easiest and the clearest way to get access. However, it has some disadvantages, here is some of them:</p>
<ul>
<li>Each test has to be declared as a friend</li>
<li>Subclasses do not inheritance friendship relation</li>
</ul>
<p>In other words, it is harder to share code between tests. Hence if you want to share code or expect it to be useful in other tests, you should consider making members in a tested class protected and introduce a shared test-only class which expose those members via public functions, or even making members publicly accessible right away in a product class. If it is not an option to change members visibility, one can create a friend class which exposes members.</p>
<h3 id="death-tests">Death tests</h3>
<p>You can not use death tests inside <code>TEST_OTHER_VM</code> and <code>TEST_VM_ASSERT*</code>.</p>
<p>We tried to make Hotspot-GoogleTest integration as transparent as possible, however, due to the current implementation of <code>TEST_OTHER_VM</code> and <code>TEST_VM_ASSERT*</code> tests, you cannot use death test functionality in them. These tests are implemented as GoogleTest death tests, and GoogleTest does not allow to have a death test inside another death test.</p>
<h3 id="external-flags">External flags</h3>
<p>Passing external flags to a tested JVM is not supported.</p>
<p>The rationality of such design decision is to simplify both tests and a test framework and to avoid failures related to incompatible flags combination till there is a good solution for that. However there are cases when one wants to test a JVM with specific flags combination, <code>_JAVA_OPTIONS</code> environment variable can be used to do that. Flags from <code>_JAVA_OPTIONS</code> will be used in <code>TEST_VM</code>, <code>TEST_OTHER_VM</code> and <code>TEST_VM_ASSERT*</code> tests.</p>
<h3 id="test-specific-flags">Test-specific flags</h3>
<p>Passing flags to a tested JVM in <code>TEST_OTHER_VM</code> and <code>TEST_VM_ASSERT*</code> should be possible, but is not implemented yet.</p>
<p>Facility to pass test-specific flags is needed for system, regression or other types of tests which require a fully initialized JVM in some particular configuration, e.g. with Serial GC selected. There is no support for such tests now, however, there is a plan to add that in upcoming releases.</p>
<p>For now, if a test depends on flags values, it should have <code>if (!&lt;flag&gt;) { return }</code> guards in the very beginning and <code>@requires</code> comment similar to jtreg <code>@requires</code> directive right before test macros. <a href="https://hg.openjdk.java.net/jdk/jdk/file/tip/test/hotspot/gtest/gc/g1/test_g1IHOPControl.cpp" class="uri">https://hg.openjdk.java.net/jdk/jdk/file/tip/test/hotspot/gtest/gc/g1/test_g1IHOPControl.cpp</a> ha an example of this temporary workaround. It is important to follow that pattern as it allows us to easily find all such tests and update them as soon as there is an implementation of flag passing facility.</p>
<p>In long-term, we expect jtreg to support GoogleTest tests as first class citizens, that is to say, jtreg will parse <span class="citation" data-cites="requires">@requires</span> comments and filter out inapplicable tests.</p>
<h3 id="flag-restoring">Flag restoring</h3>
<p>Restore changed flags.</p>
<p>It is quite common for tests to configure JVM in a certain way changing flags values. GoogleTest provides two ways to set up environment before a test and restore it afterward: using either constructor and destructor or <code>SetUp</code> and <code>TearDown</code> functions. Both ways require to use a test fixture class, which sometimes is too wordy. The simpler facilities like <code>FLAG_GUARD</code> macro or <code>*FlagSetting</code> classes could be used in such cases to restore/set values.</p>
<p>Caveats:</p>
<ul>
<li><p>Changing a flags value could break the invariants between flags' values and hence could lead to unexpected/unsupported JVM state.</p></li>
<li><p><code>FLAG_SET_*</code> macros can change more than one flag (in order to maintain invariants) so it is hard to predict what flags will be changed and it makes restoring all changed flags a nontrivial task. Thus in case one uses <code>FLAG_SET_*</code> macros, they should use <code>TEST_OTHER_VM</code> test type.</p></li>
</ul>
<h3 id="googletest-documentation">GoogleTest documentation</h3>
<p>In case you have any questions regarding GoogleTest itself, its asserts, test declaration macros, other macros, etc, please consult its documentation.</p>
<h2 id="todo">TODO</h2>
<p>Although this document provides guidelines on the most important parts of test development using GTest, it still misses a few items:</p>

% Native/Unit Test Development Guidelines
The purpose of these guidelines is to establish a shared vision on
what kind of native tests and how we want to develop them for Hotspot
using GoogleTest. Hence these guidelines include style items as well
as test approach items.
First section of this document describes properties of good tests
which are common for almost all types of test regardless of language,
framework, etc. Further sections provide recommendations to achieve
those properties and other HotSpot and/or GoogleTest specific
guidelines.
## Good test properties
### Lightness
Use the most lightweight type of tests.
In Hotspot, there are 3 different types of tests regarding their
dependency on a JVM, each next level is slower than previous
* `TEST` : a test does not depend on a JVM
* `TEST_VM` : a test does depend on an initialized JVM, but are
supposed not to break a JVM, i.e. leave it in a workable state.
* `TEST_OTHER_VM` : a test depends on a JVM and requires a freshly
initialized JVM or leaves a JVM in non-workable state
### Isolation
Tests have to be isolated: not to have visible side-effects,
influences on other tests results.
Results of one test should not depend on test execution order, other
tests, otherwise it is becoming almost impossible to find out why a
test failed. Due to hotspot-specific, it is not so easy to get a full
isolation, e.g. we share an initialized JVM between all `TEST_VM` tests,
so if your test changes JVM's state too drastically and does not
change it back, you had better consider `TEST_OTHER_VM`.
### Atomicity and self-containment
Tests should be *atomic* and *self-contained* at the same time.
One test should check a particular part of a class, subsystem,
functionality, etc. Then it is quite easy to determine what parts of a
product are broken basing on test failures. On the other hand, a test
should test that part more-or-less entirely, because when one sees a
test `FooTest::bar`, they assume all aspects of bar from `Foo` are tested.
However, it is impossible to cover all aspects even of a method, not
to mention a subsystem. In such cases, it is recommended to have
several tests, one for each aspect of a thing under test. For example
one test to tests how `Foo::bar` works if an argument is `null`, another
test to test how it works if an argument is acceptable but `Foo` is not
in the right state to accept it and so on. This helps not only to make
tests atomic, self-contained but also makes test name self-descriptive
(discussed in more details in [Test names](#test-names)).
### Repeatability
Tests have to be repeatable.
Reproducibility is very crucial for a test. No one likes sporadic test
failures, they are hard to investigate, fix and verify a fix.
In some cases, it is quite hard to write a 100% repeatable test, since
besides a test there can be other moving parts, e.g. in case of
`TEST_VM` there are several concurrently running threads. Despite this,
we should try to make a test as reproducible as possible.
### Informativeness
In case of a failure, a test should be as *informative* as possible.
Having more information about a test failure than just compared values
can be very useful for failure troubleshooting, it can reduce or even
completely eliminate debugging hours. This is even more important in
case of not 100% reproducible failures.
Achieving this property, one can easily make a test too verbose, so it
will be really hard to find useful information in the ocean of useless
information. Hence they should not only think about how to provide
[good information](#error-messages), but also
[when to do it](#uncluttered-output).
### Testing instead of visiting
Tests should *test*.
It is not enough just to "visit" some code, a test should check that
code does that it has to do, compare return values with expected
values, check that desired side effects are done, and undesired are
not, and so on. In other words, a test should contain at least one
GoogleTest assertion and do not rely on JVM asserts.
Generally speaking to write a good test, one should create a model of
the system under tests, a model of possible bugs (or bugs which one
wants to find) and design tests using those models.
### Nearness
Prefer having checks inside test code.
Not only does having test logic outside, e.g. verification method,
depending on asserts in product code contradict with several items
above but also decreases tests readability and stability. It is much
easier to understand that a test is testing when all testing logic is
located inside a test or nearby in shared test libraries. As a rule of
thumb, the closer a check to a test, the better.
## Asserts
### Several checks
Prefer `EXPECT` over `ASSERT` if possible.
This is related to the [informativeness](#informativeness) property of
tests, information for other checks can help to better localize a
defects root-cause. One should use `ASSERT` if it is impossible to
continue test execution or if it does not make much sense. Later in
the text, `EXPECT` forms will be used to refer to both
`ASSERT/EXPECT`.
When it is possible to make several different checks, but impossible
to continue test execution if at least one check fails, you can
use `::testing::Test::HasNonfatalFailure()` function. The recommended
way to express that is
`ASSERT_FALSE(::testing::Test::HasNonfatalFailure())`. Besides making it
clear why a test is aborted, it also allows you to provide more
information about a failure.
### First parameter is expected value
In all equality assertions, expected values should be passed as the
first parameter.
This convention is adopted by GoogleTest, and there is a slight
difference in how GoogleTest treats parameters, the most important one
is `null` detection. Due to different reasons, `null` detection is enabled
only for the first parameter, that is to said `EXPECT_EQ(NULL, object)`
checks that object is `null`, while `EXPECT_EQ(object, NULL)` checks that
object equals to `NULL`, GoogleTest is very strict regarding types of
compared values so the latter will generates a compile-time error.
### Floating-point comparison
Use floating-point special macros to compare `float/double` values.
Because of floating-point number representations and round-off errors,
regular equality comparison will not return true in most cases. There
are special `EXPECT_FLOAT_EQ/EXPECT_DOUBLE_EQ` assertions which check
that the distance between compared values is not more than 4 ULPs,
there is also `EXPECT_NEAR(v1, v2, eps)` which checks that the absolute
value of the difference between `v1` and `v2` is not greater than `eps`.
### C string comparison
Use string special macros for C strings comparisons.
`EXPECT_EQ` just compares pointers values, which is hardly what one
wants comparing C strings. GoogleTest provides `EXPECT_STREQ` and
`EXPECT_STRNE` macros to compare C string contents. There are also
case-insensitive versions `EXPECT_STRCASEEQ`, `EXPECT_STRCASENE`.
### Error messages
Provide informative, but not too verbose error messages.
All GoogleTest asserts print compared expressions and their values, so
there is no need to have them in error messages. Asserts print only
compared values, they do not print any of interim variables, e.g.
`ASSERT_TRUE((val1 == val2 && isFail(foo(8)) || i == 18)` prints only
one value. If you use some complex predicates, please consider
`EXPECT_PRED*` or `EXPECT_FORMAT_PRED` assertions family, they check that
a predicate returns true/success and print out all parameters values.
However in some cases, default information is not enough, a commonly
used example is an assert inside a loop, GoogleTest will not print
iteration values (unless it is an assert's parameter). Other
demonstrative examples are printing error code and a corresponding
error message; printing internal states which might have an impact on
results. One should add this information to assert message using `<<`
operator.
### Uncluttered output
Print information only if it is needed.
Too verbose tests which print all information even if they pass are
very bad practice. They just pollute output, so it becomes harder to
find useful information. In order not print information till it is
really needed, one should consider saving it to a temporary buffer and
pass to an assert.
<https://hg.openjdk.java.net/jdk/jdk/file/tip/test/hotspot/gtest/gc/shared/test_memset_with_concurrent_readers.cpp>
has a good example how to do that.
### Failures propagation
Wrap a subroutine call into `EXPECT_NO_FATAL_FAILURE` macro to
propagate failures.
`ASSERT` and `FAIL` abort only the current function, so if you have them
in a subroutine, a test will not be aborted after the subroutine even
if `ASSERT` or `FAIL` fails. You should call such subroutines in
`ASSERT_NO_FATAL_FAILURE` macro to propagate fatal failures and abort a
test. `(EXPECT|ASSERT)_NO_FATAL_FAILURE` can also be used to provide
more information.
Due to obvious reasons, there are no
`(EXPECT|ASSERT)_NO_NONFATAL_FAILURE` macros. However, if you need to
check if a subroutine generated a nonfatal failure (failed an `EXPECT`),
you can use `::testing::Test::HasNonfatalFailure` function,
or `::testing::Test::HasFailure` function to check if a subroutine
generated any failures, see [Several checks](#several-checks).
## Naming and Grouping
### Test group names
Test group names should be in CamelCase, start and end with a letter.
A test group should be named after tested class, functionality,
subsystem, etc.
This naming scheme helps to find tests, filter them and simplifies
test failure analysis. For example, class `Foo` - test group `Foo`,
compiler logging subsystem - test group `CompilerLogging`, G1 GC — test
group `G1GC`, and so forth.
### Filename
A test file must have `test_` prefix and `.cpp` suffix.
Both are actually requirements from the current build system to
recognize your tests.
### File location
Test file location should reflect a location of the tested part of the product.
* All unit tests for a class from `foo/bar/baz.cpp` should be placed
`foo/bar/test_baz.cpp` in `hotspot/test/native/` directory. Having all
tests for a class in one file is a common practice for unit tests, it
helps to see all existing tests at once, share functions and/or
resources without losing encapsulation.
* For tests which test more than one class, directory hierarchy should
be the same as product hierarchy, and file name should reflect the
name of the tested subsystem/functionality. For example, if a
sub-system under tests belongs to `gc/g1`, tests should be placed in
`gc/g1` directory.
Please note that framework prepends directory name to a test group
name. For example, if `TEST(foo, check_this)` and `TEST(bar, check_that)`
are defined in `hotspot/test/native/gc/shared/test_foo.cpp` file, they
will be reported as `gc/shared/foo::check_this` and
`gc/shared/bar::check_that`.
### Test names
Test names should be in small_snake_case, start and end with a letter.
A test name should reflect that a test checks.
Such naming makes tests self-descriptive and helps a lot during the
whole test life cycle. It is easy to do test planning, test inventory,
to see what things are not tested, to review tests, to analyze test
failures, to evolve a test, etc. For example
`foo_return_0_if_name_is_null` is better than `foo_sanity` or `foo_basic` or
just `foo`, `humongous_objects_can_not_be_moved_by_young_gc` is better
than `ho_young_gc`.
Actually using underscore is against GoogleTest project convention,
because it can lead to illegal identifiers, however, this is too
strict. Restricting usage of underscore for test names only and
prohibiting test name starts or ends with an underscore are enough to
be safe.
### Fixture classes
Fixture classes should be named after tested classes, subsystems, etc
(follow [Test group names rule](#test-group-names)) and have
`Test` suffix to prevent class name conflicts.
### Friend classes
All test purpose friends should have either `Test` or `Testable` suffix.
It greatly simplifies understanding of friendships purpose and allows
statically check that private members are not exposed unexpectedly.
Having `FooTest` as a friend of `Foo` without any comments will be
understood as a necessary evil to get testability.
### OS/CPU specific tests
Guard OS/CPU specific tests by `#ifdef` and have OS/CPU name in filename.
For the time being, we do not support separate directories for OS,
CPU, OS-CPU specific tests, in case we will have lots of such tests,
we will change directory layout and build system to support that in
the same way it is done in hotspot.
## Miscellaneous
### Hotspot style
Abide the norms and rules accepted in Hotspot style guide.
Tests are a part of Hotspot, so everything (if applicable) we use for
Hotspot, should be used for tests as well. Those guidelines cover
test-specific things.
### Code/test metrics
Coverage information and other code/test metrics are quite useful to
decide what tests should be written, what tests should be improved and
what can be removed.
For unit tests, widely used and well-known coverage metric is branch
coverage, which provides good quality of tests with relatively easy
test development process. For other levels of testing, branch coverage
is not as good, and one should consider others metrics, e.g.
transaction flow coverage, data flow coverage.
### Access to non-public members
Use explicit friend class to get access to non-public members.
We do not use GoogleTest macro to declare friendship relation,
because, from our point of view, it is less clear than an explicit
declaration.
Declaring a test fixture class as a friend class of a tested test is
the easiest and the clearest way to get access. However, it has some
disadvantages, here is some of them:
* Each test has to be declared as a friend
* Subclasses do not inheritance friendship relation
In other words, it is harder to share code between tests. Hence if you
want to share code or expect it to be useful in other tests, you
should consider making members in a tested class protected and
introduce a shared test-only class which expose those members via
public functions, or even making members publicly accessible right
away in a product class. If it is not an option to change members
visibility, one can create a friend class which exposes members.
### Death tests
You can not use death tests inside `TEST_OTHER_VM` and `TEST_VM_ASSERT*`.
We tried to make Hotspot-GoogleTest integration as transparent as
possible, however, due to the current implementation of `TEST_OTHER_VM`
and `TEST_VM_ASSERT*` tests, you cannot use death test functionality in
them. These tests are implemented as GoogleTest death tests, and
GoogleTest does not allow to have a death test inside another death
test.
### External flags
Passing external flags to a tested JVM is not supported.
The rationality of such design decision is to simplify both tests and
a test framework and to avoid failures related to incompatible flags
combination till there is a good solution for that. However there are
cases when one wants to test a JVM with specific flags combination,
`_JAVA_OPTIONS` environment variable can be used to do that. Flags from
`_JAVA_OPTIONS` will be used in `TEST_VM`, `TEST_OTHER_VM` and
`TEST_VM_ASSERT*` tests.
### Test-specific flags
Passing flags to a tested JVM in `TEST_OTHER_VM` and `TEST_VM_ASSERT*`
should be possible, but is not implemented yet.
Facility to pass test-specific flags is needed for system, regression
or other types of tests which require a fully initialized JVM in some
particular configuration, e.g. with Serial GC selected. There is no
support for such tests now, however, there is a plan to add that in
upcoming releases.
For now, if a test depends on flags values, it should have `if
(!<flag>) { return }` guards in the very beginning and `@requires`
comment similar to jtreg `@requires` directive right before test macros.
<https://hg.openjdk.java.net/jdk/jdk/file/tip/test/hotspot/gtest/gc/g1/test_g1IHOPControl.cpp>
ha an example of this temporary workaround. It is important to follow
that pattern as it allows us to easily find all such tests and update
them as soon as there is an implementation of flag passing facility.
In long-term, we expect jtreg to support GoogleTest tests as first
class citizens, that is to say, jtreg will parse @requires comments
and filter out inapplicable tests.
### Flag restoring
Restore changed flags.
It is quite common for tests to configure JVM in a certain way
changing flags values. GoogleTest provides two ways to set up
environment before a test and restore it afterward: using either
constructor and destructor or `SetUp` and `TearDown` functions. Both ways
require to use a test fixture class, which sometimes is too wordy. The
simpler facilities like `FLAG_GUARD` macro or `*FlagSetting` classes could
be used in such cases to restore/set values.
Caveats:
* Changing a flags value could break the invariants between flags' values and hence could lead to unexpected/unsupported JVM state.
* `FLAG_SET_*` macros can change more than one flag (in order to
maintain invariants) so it is hard to predict what flags will be
changed and it makes restoring all changed flags a nontrivial task.
Thus in case one uses `FLAG_SET_*` macros, they should use `TEST_OTHER_VM`
test type.
### GoogleTest documentation
In case you have any questions regarding GoogleTest itself, its
asserts, test declaration macros, other macros, etc, please consult
its documentation.
## TODO

This document describes system properties that are used for internal
debugging and instrumentation purposes, along with the system loggers,
which are used for the same thing.
This document is intended as a developer resource, and it is not
needed as Nashorn documentation for normal usage. Flags and system
properties described herein are subject to change without notice.
=====================================
1. System properties used internally
=====================================
This documentation of the system property flags assume that the
default value of the flag is false, unless otherwise specified.
SYSTEM PROPERTY: -Dnashorn.args=<string>
This property takes as its value a space separated list of Nashorn
command line options that should be passed to Nashorn. This might be
useful in environments where it is hard to tell how a nashorn.jar is
launched.
Example:
> java -Dnashorn.args="--lazy-complation --log=compiler" large-java-app-with-nashorn.jar
> ant -Dnashorn.args="--log=codegen" antjob
SYSTEM PROPERTY: -Dnashorn.args.prepend=<string>
This property behaves like nashorn.args, but adds the given arguments
before the existing ones instead of after them. Later arguments will
overwrite earlier ones, so this is useful for setting default arguments
that can be overwritten.
SYSTEM PROPERTY: -Dnashorn.unstable.relink.threshold=x
NOTE: This property is deprecated in favor of the
"--unstable-relink-threshold" command line option. It controls how many
call site misses are allowed before a callsite is relinked with "apply"
semantics to never change again. In the case of megamorphic callsites,
this is necessary, or the program would spend all its time swapping out
callsite targets. When neither the system property nor the command line
option are specified, defaults to 8, or 16 with optimistic types turned
on.
SYSTEM PROPERTY: -Dnashorn.compiler.splitter.threshold=x
This will change the node weight that requires a subgraph of the IR to
be split into several classes in order not to run out of bytecode space.
The default value is 0x8000 (32768).
SYSTEM PROPERTY: -Dnashorn.serialize.compression=<x>
This property sets the compression level used when deflating serialized
AST structures of anonymous split functions. Valid values range from 0 to 9,
the default value is 4. Higher values will reduce memory size of serialized
AST but increase CPU usage required for compression.
SYSTEM PROPERTY: -Dnashorn.codegen.debug.trace=<x>
See the description of the codegen logger below.
SYSTEM PROPERTY: -Dnashorn.fields.objects, -Dnashorn.fields.dual
When the nashorn.fields.objects property is true, Nashorn will always
use object fields for AccessorProperties, requiring boxing for all
primitive property values. When nashorn.fields.dual is set, Nashorn
will always use dual long/object fields, which allows primitives to be
stored without boxing. When neither system property is set, Nashorn
chooses a setting depending on the optimistic types setting (dual
fields when optimistic types are enabled, object-only fields otherwise).
With dual fields, Nashorn uses long fields to store primitive values.
Ints are represented as the 32 low bits of the long fields. Doubles
are represented as the doubleToLongBits of their value. This way a
single field can be used for all primitive types. Packing and
unpacking doubles to their bit representation is intrinsified by
the JVM and extremely fast.
In the future, this might complement or be replaced by experimental
feature sun.misc.TaggedArray, which has been discussed on the mlvm
mailing list. TaggedArrays are basically a way to share data space
between primitives and references, and have the GC understand this.
SYSTEM PROPERTY: -Dnashorn.compiler.symbol.trace=[<x>[,*]],
-Dnashorn.compiler.symbol.stacktrace=[<x>[,*]]
When this property is set, creation and manipulation of any symbol
named "x" will show information about when the compiler changes its
type assumption, bytecode local variable slot assignment and other
data. This is useful if, for example, a symbol shows up as an Object,
when you believe it should be a primitive. Usually there is an
explanation for this, for example that it exists in the global scope
and type analysis has to be more conservative.
Several symbols names to watch can be specified by comma separation.
If no variable name is specified (and no equals sign), all symbols
will be watched
By using "stacktrace" instead of or together with "trace", stack
traces will be displayed upon symbol changes according to the same
semantics.
SYSTEM PROPERTY: -Dnashorn.lexer.xmlliterals
If this property it set, it means that the Lexer should attempt to
parse XML literals, which would otherwise generate syntax
errors. Warning: there are currently no unit tests for this
functionality.
XML literals, when this is enabled, end up as standard LiteralNodes in
the IR.
SYSTEM_PROPERTY: -Dnashorn.debug
If this property is set to true, Nashorn runs in Debug mode. Debug
mode is slightly slower, as for example statistics counters are enabled
during the run. Debug mode makes available a NativeDebug instance
called "Debug" in the global space that can be used to print property
maps and layout for script objects, as well as a "dumpCounters" method
that will print the current values of the previously mentioned stats
counters.
These functions currently exists for Debug:
"map" - print(Debug.map(x)) will dump the PropertyMap for object x to
stdout (currently there also exist functions called "embedX", where X
is a value from 0 to 3, that will dump the contents of the embed pool
for the first spill properties in any script object and "spill", that
will dump the contents of the growing spill pool of spill properties
in any script object. This is of course subject to change without
notice, should we change the script object layout.
"methodHandle" - this method returns the method handle that is used
for invoking a particular script function.
"identical" - this method compares two script objects for reference
equality. It is a == Java comparison
"equals" - Returns true if two objects are either referentially
identical or equal as defined by java.lang.Object.equals.
"dumpCounters" - will dump the debug counters' current values to
stdout.
Currently we count number of ScriptObjects in the system, number of
Scope objects in the system, number of ScriptObject listeners added,
removed and dead (without references).
We also count number of ScriptFunctions, ScriptFunction invocations
and ScriptFunction allocations.
Furthermore we count PropertyMap statistics: how many property maps
exist, how many times were property maps cloned, how many times did
the property map history cache hit, prevent new allocations, how many
prototype invalidations were done, how many time the property map
proto cache hit.
Finally we count callsite misses on a per callsite bases, which occur
when a callsite has to be relinked, due to a previous assumption of
object layout being invalidated.
"getContext" - return the current Nashorn context.
"equalWithoutType" - Returns true if if the two objects are both
property maps, and they have identical properties in the same order,
but allows the properties to differ in their types.
"diffPropertyMaps" Returns a diagnostic string representing the difference
of two property maps.
"getClass" - Returns the Java class of an object, or undefined if null.
"toJavaString" - Returns the Java toString representation of an object.
"toIdentString" - Returns a string representation of an object consisting
of its java class name and hash code.
"getListenerCount" - Return the number of property listeners for a
script object.
"getEventQueueCapacity" - Get the capacity of the event queue.
"setEventQueueCapacity" - Set the event queue capacity.
"addRuntimeEvent" - Add a runtime event to the runtime event queue.
The queue has a fixed size (see -Dnashorn.runtime.event.queue.size)
and the oldest entry will be thrown out of the queue is about to overflow.
"expandEventQueueCapacity" - Expands the event queue capacity,
or truncates if capacity is lower than current capacity. Then only
the newest entries are kept.
"clearRuntimeEvents" - Clear the runtime event queue.
"removeRuntimeEvent" - Remove a specific runtime event from the event queue.
"getRuntimeEvents" - Return all runtime events in the queue as an array.
"getLastRuntimeEvent" - Return the last runtime event in the queue.
SYSTEM PROPERTY: -Dnashorn.methodhandles.debug.stacktrace
This enhances methodhandles logging (see below) to also dump the
stack trace for every instrumented method handle operation.
Warning: This is enormously verbose, but provides a pretty
decent "grep:able" picture of where the calls are coming from.
SYSTEM PROPERTY: -Dnashorn.cce
Setting this system property causes the Nashorn linker to rely on
ClassCastExceptions for triggering a callsite relink. If not set, the linker
will add an explicit instanceof guard.
SYSTEM PROPERTY: -Dnashorn.spill.threshold=<x>
This property sets the number of fields in an object from which to use
generic array based spill storage instead of Java fields. The default value
is 256.
SYSTEM PROPERTY: -Dnashorn.tcs.miss.samplePercent=<x>
When running with the trace callsite option (-tcs), Nashorn will count
and instrument any callsite misses that require relinking. As the
number of relinks is large and usually produces a lot of output, this
system property can be used to constrain the percentage of misses that
should be logged. Typically this is set to 1 or 5 (percent). 1% is the
default value.
SYSTEM PROPERTY: -Dnashorn.persistent.code.cache
This property can be used to set the directory where Nashorn stores
serialized script classes generated with the -pcc/--persistent-code-cache
option. The default directory name is "nashorn_code_cache".
SYSTEM PROPERTY: -Dnashorn.typeInfo.maxFiles
Maximum number of files to store in the type info cache. The type info cache
is used to cache type data of JavaScript functions when running with
optimistic types (-ot/--optimistic-types). There is one file per JavaScript
function in the cache.
The default value is 0 which means the feature is disabled. Setting this
to something like 20000 is probably good enough for most applications and
will usually cap the cache directory to about 80MB presuming a 4kB
filesystem allocation unit. Set this to "unlimited" to run without limit.
If the value is not 0 or "unlimited", Nashorn will spawn a cleanup thread
that makes sure the number of files in the cache does not exceed the given
value by deleting the least recently modified files.
SYSTEM PROPERTY: -Dnashorn.typeInfo.cacheDir
This property can be used to set the directory where Nashorn stores the
type info cache when -Dnashorn.typeInfo.maxFiles is set to a nonzero
value. The default location is platform specific. On Windows, it is
"${java.io.tmpdir}\com.oracle.java.NashornTypeInfo". On Linux and
Solaris it is "~/.cache/com.oracle.java.NashornTypeInfo". On Mac OS X,
it is "~/Library/Caches/com.oracle.java.NashornTypeInfo".
SYSTEM PROPERTY: -Dnashorn.typeInfo.cleanupDelaySeconds=<value>
This sets the delay between cleanups of the typeInfo cache, in seconds.
The default delay is 20 seconds.
SYSTEM PROPERTY: -Dnashorn.profilefile=<filename>
When running with the profile callsite options (-pcs), Nashorn will
dump profiling data for all callsites to stderr as a shutdown hook. To
instead redirect this to a file, specify the path to the file using
this system property.
SYSTEM_PROPERTY: -Dnashorn.regexp.impl=[jdk|joni]
This property defines the regular expression engine to be used by
Nashorn. Set this flag to "jdk" to get an implementation based on the
JDK's java.util.regex package. Set this property to "joni" to install
an implementation based on Joni, the regular expression engine used by
the JRuby project. The default value for this flag is "joni"
SYSTEM PROPERTY: -Dnashorn.runtime.event.queue.size=<value>
Nashorn provides a fixed sized runtime event queue for debugging purposes.
See -Dnashorn.debug for methods to access the event queue.
The default value is 1024.
SYSTEM PROPERTY: -Dnashorn.anonymous.classes.threshold=<value>
Nashorn can use anonymous classes for loading compiled scripts, depending
on the --anonymous-classes=[auto|true|false] option. Anonymous classes load
faster, but the loaded classes get less optimization applied to them and
therefore usually run slower. In the default "auto" setting, scripts are
loaded as anonymous classes if the script size does not exceed 512 bytes.
The above system property allows to set this threshold to a user defined
value.
===============
2. The loggers.
===============
It is very simple to create your own logger. Use the DebugLogger class
and give the subsystem name as a constructor argument.
The Nashorn loggers can be used to print per-module or per-subsystem
debug information with different levels of verbosity. The loggers for
a given subsystem are available are enabled by using
--log=<systemname>[:<level>]
on the command line.
Here <systemname> identifies the name of the subsystem to be logged
and the optional colon and level argument is a standard
java.util.logging.Level name (severe, warning, info, config, fine,
finer, finest). If the level is left out for a particular subsystem,
it defaults to "info". Any log message logged as the level or a level
that is more important will be output to stderr by the logger.
Several loggers can be enabled by a single command line option, by
putting a comma after each subsystem/level tuple (or each subsystem if
level is unspecified). The --log option can also be given multiple
times on the same command line, with the same effect.
For example: --log=codegen,fields:finest is equivalent to
--log=codegen:info --log=fields:finest
The following is an incomplete list of subsystems that currently
support logging. Look for classes implementing
jdk.nashorn.internal.runtime.logging.Loggable for more loggers.
* compiler
The compiler is in charge of turning source code and function nodes
into byte code, and installs the classes into a class loader
controlled from the Context. Log messages are, for example, about
things like new compile units being allocated. The compiler has global
settings that all the tiers of codegen (e.g. Lower and CodeGenerator)
use.s
* recompile
This logger shows information about recompilation of scripts and
functions at runtime. Recompilation may happen because a function
was called with different parameter types, or because an optimistic
assumption failed while executing a function with -ot/--optimistic-types.
* codegen
The code generator is the emitter stage of the code pipeline, and
turns the lowest tier of a FunctionNode into bytecode. Codegen logging
shows byte codes as they are being emitted, line number information
and jumps. It also shows the contents of the bytecode stack prior to
each instruction being emitted. This is a good debugging aid. For
example:
[codegen] #41 line:2 (f)_afc824e
[codegen] #42 load symbol x slot=2
[codegen] #43 {1:O} load int 0
[codegen] #44 {2:I O} dynamic_runtime_call GT:ZOI_I args=2 returnType=boolean
[codegen] #45 signature (Ljava/lang/Object;I)Z
[codegen] #46 {1:Z} ifeq ternary_false_5402fe28
[codegen] #47 load symbol x slot=2
[codegen] #48 {1:O} goto ternary_exit_107c1f2f
[codegen] #49 ternary_false_5402fe28
[codegen] #50 load symbol x slot=2
[codegen] #51 {1:O} convert object -> double
[codegen] #52 {1:D} neg
[codegen] #53 {1:D} convert double -> object
[codegen] #54 {1:O} ternary_exit_107c1f2f
[codegen] #55 {1:O} return object
shows a ternary node being generated for the sequence "return x > 0 ?
x : -x"
The first number on the log line is a unique monotonically increasing
emission id per bytecode. There is no guarantee this is the same id
between runs. depending on non deterministic code
execution/compilation, but for small applications it usually is. If
the system variable -Dnashorn.codegen.debug.trace=<x> is set, where x
is a bytecode emission id, a stack trace will be shown as the
particular bytecode is about to be emitted. This can be a quick way to
determine where it comes from without attaching the debugger. "Who
generated that neg?"
The --log=codegen option is equivalent to setting the system variable
"nashorn.codegen.debug" to true.
* fold
Shows constant folding taking place before lowering
* lower
This is the first lowering pass.
Lower is a code generation pass that turns high level IR nodes into
lower level one, for example substituting comparisons to RuntimeNodes
and inlining finally blocks.
Lower is also responsible for determining control flow information
like end points.
* symbols
The symbols logger tracks the assignment os symbols to identifiers.
* scopedepths
This logs the calculation of scope depths for non-local symbols.
* fields
The --log=fields option (at info level) is equivalent to setting the
system variable "nashorn.fields.debug" to true. At the info level it
will only show info about type assumptions that were invalidated. If
the level is set to finest, it will also trace every AccessorProperty
getter and setter in the program, show arguments, return values
etc. It will also show the internal representation of respective field
(Object in the normal case, unless running with the dual field
representation)
* time
This enables timers for various phases of script compilation. The timers
will be dumped when the Nashorn process exits. We see a percentage value
of how much time was spent not executing bytecode (i.e. compilation and
internal tasks) at the end of the report.
A finer level than "info" will show individual compilation timings as they
happen.
Here is an example:
[time] Accumulated complation phase Timings:
[time]
[time] 'JavaScript Parsing' 1076 ms
[time] 'Constant Folding' 159 ms
[time] 'Control Flow Lowering' 303 ms
[time] 'Program Point Calculation' 282 ms
[time] 'Builtin Replacement' 71 ms
[time] 'Code Splitting' 670 ms
[time] 'Symbol Assignment' 474 ms
[time] 'Scope Depth Computation' 249 ms
[time] 'Optimistic Type Assignment' 186 ms
[time] 'Local Variable Type Calculation' 526 ms
[time] 'Bytecode Generation' 5177 ms
[time] 'Class Installation' 1854 ms
[time]
[time] Total runtime: 11994 ms (Non-runtime: 11027 ms [91%])
* methodhandles
If this logger is enabled, each MethodHandle related call that uses
the java.lang.invoke package gets its MethodHandle intercepted and an
instrumentation printout of arguments and return value appended to
it. This shows exactly which method handles are executed and from
where. (Also MethodTypes and SwitchPoints).
* classcache
This logger shows information about reusing code classes using the
in-memory class cache. Nashorn will try to avoid compilation of
scripts by using existing classes. This can significantly improve
performance when repeatedly evaluating the same script.
=======================
3. Undocumented options
=======================
Here follows a short description of undocumented options for Nashorn.
To see a list of all undocumented options, use the (undocumented) flag
"-xhelp".
i.e. jjs -xhelp or java -jar nashorn.jar -xhelp
Undocumented options are not guaranteed to work, run correctly or be
bug free. They are experimental and for internal or debugging use.
They are also subject to change without notice.
In practice, though, all options below not explicitly documented as
EXPERIMENTAL can be relied upon, for example --dump-on-error is useful
for any JavaScript/Nashorn developer, but there is no guarantee.

<h2><span>Who is the Java Scripting API For?</span></h2>
<span>Some useful characteristics of scripting languages
are:</span>
<ul>
<li><span><b>Convenience</b>: Most scripting languages are
dynamically typed. You can usually create new variables without
declaring the variable type, and you can reuse variables to store
objects of different types. Also, scripting languages tend to
perform many type conversions automatically, for example,
converting the number 10 to the text "10" as necessary.</span></li>
<li><span><b>Developing rapid prototypes</b>: You can avoid the
edit-compile-run cycle and just use edit-run!</span></li>
<li><span><b>Application extension/customization</b>: You can
"externalize" parts of your application - like configuration
scripts, business logic/rules and math expressions for financial
applications.</span></li>
<li><span><b>"Command line" shells for applications</b> -for
debugging, runtime/deploy time configuration etc. Most applications
have a web-based GUI configuaration tool these days. But
sysadmins/deployers frequently prefer command line tools. Instead
of inventing ad-hoc scripting language for that purpose, a
"standard" scripting language can be used.</span></li>
</ul>
<p><span>The Java<font size="-1"><sup>TM</sup></font> Scripting API
is a scripting language indepedent framework for using script
engines from Java code. With the Java Scripting API, it is possible
to write customizable/extendable applications in the Java language
and leave the customization scripting language choice to the end
user. The Java application developer need not choose the extension
language during development. If you write your application with
JSR-223 API, then your users can use any JSR-223 compliant
scripting language.</span></p>
<hr>
<span><a name="package" id="package"></a></span>
<h2><span>Scripting Package</span></h2>
<p><span>The Java Scripting functionality is in the <code><a href="http://docs.oracle.com/javase/9/docs/api/javax/script/package-summary.html">javax.script</a></code>
package. This is a relatively small, simple API. The starting point
of the scripting API is the <code>ScriptEngineManager</code> class.
A ScriptEngineManager object can discover script engines through
the jar file service discovery mechanism. It can also instantiate
ScriptEngine objects that interpret scripts written in a specific
scripting language. The simplest way to use the scripting API is as
follows:</span></p>
<ol>
<li><span>Create a <code>ScriptEngineManager</code>
object.</span></li>
<li><span>Get a <code>ScriptEngine</code> object from the
manager.</span></li>
<li><span>Evaluate script using the <code>ScriptEngine</code>'s
<code>eval</code> methods.</span></li>
</ol>
<p><span>Now, it is time to look at some sample code. While it is
not mandatory, it may be useful to know a bit of JavaScript to read
these examples.</span></p>
<hr>
<span><a name="examples" id="examples"></a></span>
<h2><span>Examples</span></h2>
<span><a name="helloworld" id="helloworld"></a></span>
<h3><span>"Hello, World"</span></h3>
<p><span>From the <code>ScriptEngineManager</code> instance, we
request a JavaScript engine instance using
<code>getEngineByName</code> method. On the script engine, the
<code>eval</code> method is called to execute a given String as
JavaScript code! For brevity, in this as well as in subsequent
examples, we have not shown exception handling. There are checked
and runtime exceptions thrown from <code>javax.script</code> API.
Needless to say, you have to handle the exceptions
appropriately.</span></p>
<pre>
<span><code>
// <a href="source/EvalScript.java">EvalScript.java</a>
import javax.script.*;
public class EvalScript {
public static void main(String[] args) throws Exception {
// create a script engine manager
<span class="classref">ScriptEngineManager</span> factory = new ScriptEngineManager();
// create a JavaScript engine
<span class="classref">ScriptEngine</span> engine = factory.<span class="methodref">getEngineByName</span>("nashorn");
// evaluate JavaScript code from String
engine.<span class="methodref">eval</span>("print('Hello, World')");
}
}
</code></span>
</pre>
<hr>
<a name="evalfile" id="evalfile"></a>
<h3>Evaluating a Script File</h3>
<p>In this example, we call the <code>eval</code> method that
accepts <code>java.io.Reader</code> for the input source. The
script read by the given reader is executed. This way it is
possible to execute scripts from files, URLs and resources by
wrapping the relevant input stream objects as readers.</p>
<pre>
<code>
// <a href="source/EvalFile.java">EvalFile.java</a>
import javax.script.*;
public class EvalFile {
public static void main(String[] args) throws Exception {
// create a script engine manager
<span class="classref">ScriptEngineManager</span> factory = new ScriptEngineManager();
// create JavaScript engine
<span class="classref">ScriptEngine</span> engine = factory.<span class="methodref">getEngineByName</span>("nashorn");
// evaluate JavaScript code from given file - specified by first argument
engine.<span class="methodref">eval</span>(new java.io.FileReader(args[0]));
}
}
</code>
</pre>
Let us assume that we have the file named <a href="source/test.js">test.js</a> with the
following text:
<pre><code>
print("This is hello from test.js");
</code>
</pre>
We can run the above Java as
<pre><code>
java EvalFile test.js
</code>
</pre>
<hr>
<a name="scriptvars" id="scriptvars"></a>
<h3>Script Variables</h3>
<p>When you embed script engines and scripts with your Java
application, you may want to expose your application objects as
global variables to scripts. This example demonstrates how you can
expose your application objects as global variables to a script. We
create a <code>java.io.File</code> in the application and expose
the same as a global variable with the name "file". The script can
access the variable - for example, it can call public methods on
it. Note that the syntax to access Java objects, methods and fields
is dependent on the scripting language. JavaScript supports the
most "natural" Java-like syntax.</p>
<p>
Nashorn script engine pre-defines two global variables named "context"
and "engine". The "context" variable is of type javax.script.ScriptContext
and refers to the current ScriptContext instance passed to script engine's
eval method. The "engine" variable is of type javax.script.ScriptEngine and
refers to the current nashorn script engine instance evaluating the script.
Both of these variables are non-writable, non-enumerable and non-configurable
- which implies script code can not write overwrite the value, for..loop iteration
on global object will not iterate these variables and these variables can not be
deleted by script.
<pre><code>
// <a href="source/ScriptVars.java">ScriptVars.java</a>
import javax.script.*;
import java.io.*;
public class ScriptVars {
public static void main(String[] args) throws Exception {
ScriptEngineManager manager = new ScriptEngineManager();
ScriptEngine engine = manager.getEngineByName("nashorn");
File f = new File("test.txt");
// expose File object as variable to script
engine.<span class="methodref">put</span>("file", f);
// evaluate a script string. The script accesses "file"
// variable and calls method on it
engine.eval("print(file.getAbsolutePath())");
}
}
</code>
</pre>
<hr>
<a name="invoke" id="invoke"></a>
<h3>Invoking Script Functions and Methods</h3>
<p>Sometimes you may want to call a specific scripting function
repeatedly - for example, your application menu functionality might
be implemented by a script. In your menu's action event handler you
may want to call a specific script function. The following example
demonstrates invoking a specific script function from Java
code.</p>
<pre><code>
// <a href="source/InvokeScriptFunction.java">InvokeScriptFunction.java</a>
import javax.script.*;
public class InvokeScriptFunction {
public static void main(String[] args) throws Exception {
ScriptEngineManager manager = new ScriptEngineManager();
ScriptEngine engine = manager.getEngineByName("nashorn");
// JavaScript code in a String
String script = "function hello(name) { print('Hello, ' + name); }";
// evaluate script
engine.eval(script);
// <code>javax.script.Invocable</code> is an optional interface.
// Check whether your script engine implements it or not!
// Note that the JavaScript engine implements Invocable interface.
<span class="classref">Invocable</span> inv = (Invocable) engine;
// invoke the global function named "hello"
inv.<span class="methodref">invokeFunction</span>("hello", "Scripting!!" );
}
}
</code>
</pre>
<p>If your scripting language is object based (like JavaScript) or
object-oriented, then you can invoke a script method on a script
object.</p>
<pre><code>
// <a href="source/InvokeScriptMethod.java">InvokeScriptMethod.java</a>
import javax.script.*;
public class InvokeScriptMethod {
public static void main(String[] args) throws Exception {
ScriptEngineManager manager = new ScriptEngineManager();
ScriptEngine engine = manager.getEngineByName("nashorn");
// JavaScript code in a String. This code defines a script object 'obj'
// with one method called 'hello'.
String script = "var obj = new Object(); obj.hello = function(name) { print('Hello, ' + name); }";
// evaluate script
engine.eval(script);
// <code>javax.script.Invocable</code> is an optional interface.
// Check whether your script engine implements or not!
// Note that the JavaScript engine implements Invocable interface.
<span class="classref">Invocable</span> inv = (Invocable) engine;
// get script object on which we want to call the method
Object obj = engine.<span class="methodref">get</span>("obj");
// invoke the method named "hello" on the script object "obj"
inv.<span class="methodref">invokeMethod</span>(obj, "hello", "Script Method !!" );
}
}
</code>
</pre>
<hr>
<a name="interfaces" id="interfaces"></a>
<h3>Implementing Java Interfaces by Scripts</h3>
<p>Instead of calling specific script functions from Java,
sometimes it is convenient to implement a Java interface by script
functions or methods. Also, by using interfaces we can avoid having
to use the <code>javax.script</code> API in many places. We can get
an interface implementor object and pass it to various Java APIs.
The following example demonstrates implementing the
<code>java.lang.Runnable</code> interface with a script.</p>
<pre><code>
// <a href="source/RunnableImpl.java">RunnableImpl.java</a>
import javax.script.*;
public class RunnableImpl {
public static void main(String[] args) throws Exception {
ScriptEngineManager manager = new ScriptEngineManager();
ScriptEngine engine = manager.getEngineByName("nashorn");
// JavaScript code in a String
String script = "function run() { print('run called'); }";
// evaluate script
engine.eval(script);
<span class="classref">Invocable</span> inv = (Invocable) engine;
// get Runnable interface object from engine. This interface methods
// are implemented by script functions with the matching name.
Runnable r = inv.<span class="methodref">getInterface</span>(Runnable.class);
// start a new thread that runs the script implemented

<p>If your scripting language is object-based or object-oriented,
it is possible to implement a Java interface by script methods on
script objects. This avoids having to call script global functions
for interface methods. The script object can store the "state"
associated with the interface implementor.</p>
<pre><code>
// <a href="source/RunnableImplObject.java">RunnableImplObject.java</a>
import javax.script.*;
public class RunnableImplObject {
public static void main(String[] args) throws Exception {
ScriptEngineManager manager = new ScriptEngineManager();
ScriptEngine engine = manager.getEngineByName("nashorn");
// JavaScript code in a String
String script = "var obj = new Object(); obj.run = function() { print('run method called'); }";
// evaluate script
engine.eval(script);
// get script object on which we want to implement the interface with
Object obj = engine.<span class="methodref">get</span>("obj");
<span class="classref">Invocable</span> inv = (Invocable) engine;
// get Runnable interface object from engine. This interface methods
// are implemented by script methods of object 'obj'
Runnable r = inv.<span class="methodref">getInterface</span>(obj, Runnable.class);
// start a new thread that runs the script implemented
// runnable interface
Thread th = new Thread(r);
th.start();
th.join();
}

<h3>Multiple Scopes for Scripts</h3>
<p>In the <a href="#scriptvars">script variables</a> example, we
saw how to expose application objects as script global variables.
It is possible to expose multiple global "scopes" for scripts. A
single scope is an instance of <code>javax.script.Bindings</code>.
This interface is derived from <code>java.util.Map&lt;String,
Object&gt;</code>. A scope a set of name-value pairs where name is
any non-empty, non-null String.
<code>javax.script.ScriptContext</code> interface supports multiple
scopes with associated Bindings for each
scope. By default, every script engine has a default script
context. The default script context has atleast one scope called
"ENGINE_SCOPE". Various scopes supported by a script context are
available through <code>getScopes</code> method.</p>
<pre><code>
// <a href="source/MultiScopes.java">MultiScopes.java</a>
import javax.script.*;
public class MultiScopes {
public static void main(String[] args) throws Exception {
ScriptEngineManager manager = new ScriptEngineManager();
ScriptEngine engine = manager.getEngineByName("nashorn");
engine.put("x", "hello");
// print global variable "x"
engine.eval("print(x);");
// the above line prints "hello"
// Now, pass a different script context
<span class="classref">ScriptContext</span> newContext = new <span class="classref">SimpleScriptContext</span>();
newContext.setBindings(engine.createBindings(), ScriptContext.ENGINE_SCOPE);
<span class="classref">Bindings</span> engineScope = newContext.<span class="methodref">getBindings</span>(ScriptContext.ENGINE_SCOPE);
// add new variable "x" to the new engineScope
engineScope.<span class="methodref">put</span>("x", "world");
// execute the same script - but this time pass a different script context
engine.eval("print(x);", newContext);
// the above line prints "world"
}
}

<h2>JavaScript to Java Communication</h2>
<p>For the most part, accessing Java classes, objects and methods
is straightforward. In particular field and method access from
JavaScript is the same as it is from Java. We highlight important
aspects of JavaScript Java access here.
The following examples are JavaScript snippets accessing Java. This
section requires knowledge of JavaScript. This section can be
skipped if you are planning to use some other JSR-223 scripting
language rather than JavaScript.</p>
<hr>
<a name="jsjavaclass" id=jsjavalass"></a>
<h3>Accessing Java Classes</h3>
<pre>
<code>
// <a href="source/javatypes.js">javatypes.js</a>
var arrayListType = Java.type("java.util.ArrayList")
var intType = Java.type("int")
var stringArrayType = Java.type("java.lang.String[]")
var int2DArrayType = Java.type("int[][]")
</code>
</pre>
Note that the name of the type is always a string for a fully qualified name. You can use any of these expressions to create new instances, e.g.:
<pre><code>
var anArrayList = new (Java.type("java.util.ArrayList"))
</code></pre>
or
<pre><code>
var ArrayList = Java.type("java.util.ArrayList")
var anArrayList = new ArrayList
var anArrayListWithSize = new ArrayList(16)
</code></pre>
In the special case of inner classes, you can either use the JVM fully qualified name, meaning using the dollar sign in the class name, or you can use the dot:
<pre><code>
var ftype = Java.type("java.awt.geom.Arc2D$Float")
</code></pre>
and
<pre><code>
var ftype = Java.type("java.awt.geom.Arc2D.Float")
</code></pre>
both work. Note however that using the dollar sign is faster, as Java.type first tries to resolve the class name as it is originally specified, and the internal JVM names for inner classes use the dollar sign. If you use the dot, Java.type will internally get a ClassNotFoundException and subsequently retry by changing the last dot to dollar sign. As a matter of fact, it'll keep replacing dots with dollar signs until it either successfully loads the class or runs out of all dots in the name. This way it can correctly resolve and load even multiply nested inner classes with the dot notation. Again, this will be slower than using the dollar signs in the name. An alternative way to access the inner class is as a property of the outer class:
<pre><code>
var arctype = Java.type("java.awt.geom.Arc2D")
var ftype = arctype.Float
</code></pre>
<p>
You can access both static and non-static inner classes. If you want to create an instance of a non-static inner class, remember to pass an instance of its outer class as the first argument to the constructor.
</p>
<p>
In addition to creating new instances, the type objects returned from <code>Java.type</code> calls can also be used to access the
static fields and methods of the classes:
<pre><code>
var File = Java.type("java.io.File")
File.createTempFile("nashorn", ".tmp")
</code></pre>
<p>
Methods with names of the form <code>isXxx()</code>, <code>getXxx()</code>, and <code>setXxx()</code> can also be used as properties, for both instances and statics.
</p>
<p>
A type object returned from <code>Java.type</code> is distinct from a <code>java.lang.Class</code> object. You can obtain one from the other using properties <code>class</code> and <code>static</code> on them.
<pre><code>
var ArrayList = Java.type("java.util.ArrayList")
var a = new ArrayList
// All of the following print true:
print("Type acts as target of instanceof: " + (a instanceof ArrayList))
print("Class doesn't act as target of instanceof: " + !(a instanceof a.getClass()))
print("Type is not same as instance's getClass(): " + (a.getClass() !== ArrayList))
print("Type's `class` property is same as instance getClass(): " + (a.getClass() === ArrayList.class))
print("Type is same as instance getClass()'s `static` property: " + (a.getClass().static === ArrayList))
</code></pre>
<p>
You can think of the type object as similar to the class names as used in Java source code: you use them as the
arguments to the <code>new</code> and <code>instanceof</code> operators and as the namespace for the static fields
and methods, but they are different than the runtime <code>Class</code> objects returned by <code>getClass()</code> calls.
Syntactically and semantically, this separation produces code that is most similar to Java code, where a distinction
between compile-time class expressions and runtime class objects also exists. (Also, Java can't have the equivalent of <code>static</code>
property on a <code>Class</code> object since compile-time class expressions are never reified as objects).

<h3>Importing Java Packages, Classes</h3>
<p>The built-in functions <code>importPackage</code> (in compatibility script) and
<code>importClass</code> can be used to import Java packages and
classes.</p>
<pre><code>
// <a href="source/importpackageclass.js">importpackageclass.js</a>
// load compatibility script
load("nashorn:mozilla_compat.js");
// Import Java packages and classes
// like import package.*; in Java
<span class="functionref">importPackage</span>(java.awt);
// like import java.awt.Frame in Java
<span class="functionref">importClass</span>(java.awt.Frame);
// Create Java Objects by "new ClassName"
var frame = new java.awt.Frame("hello");
// Call Java public methods from script
frame.setVisible(true);
// Access "JavaBean" properties like "fields"
print(frame.title);
</code>
</pre>
<p>The <span class="objectref">Packages</span> global variable can
be used to access Java packages. Examples:
<code>Packages.java.util.Vector</code>,
<code>Packages.javax.swing.JFrame</code>. Please note that "java"
is a shortcut for "Packages.java". There are equivalent shortcuts
for javax, org, edu, com, net prefixes, so pratically all JDK
platform classes can be accessed without the "Packages" prefix.</p>
<p>Note that java.lang is not imported by default (unlike Java)
because that would result in conflicts with JavaScript's built-in
Object, Boolean, Math and so on.</p>
<p><code>importPackage</code> and <code>importClass</code>
functions "pollute" the global variable scope of JavaScript. To
avoid that, you may use <span class="functionref">JavaImporter</span>.</p>
<pre><code>
// <a href="source/javaimporter.js">javaimporter.js</a>
// create JavaImporter with specific packages and classes to import
var SwingGui = new <span class="functionref">JavaImporter</span>(javax.swing,
javax.swing.event,
javax.swing.border,
java.awt.event);
with (SwingGui) {
// within this 'with' statement, we can access Swing and AWT
// classes by unqualified (simple) names.
var mybutton = new JButton("test");
var myframe = new JFrame("test");
}
</code>
</pre>

<a name="jsarrays" id="jsarrays"></a>
<h3>Creating, Converting and Using Java Arrays</h3>
<p>
Array element access or length access is the same as in Java.</p>
<pre><code>
// <a href="source/javaarray.js">javaarray.js</a>
// create Java String array of 5 elements
var StringArray = Java.type("java.lang.String[]");
var a = new StringArray(5);
// Accessing elements and length access is by usual Java syntax
a[0] = "scripting is great!";
print(a.length);
print(a[0]);
</code>
</pre>
<p>
It is also possible to convert between JavaScript and Java arrays.
Given a JavaScript array and a Java type, <code>Java.to</code> returns a Java array with the same initial contents, and with the specified array type.
</p>
<pre><code>
var anArray = [1, "13", false]
var javaIntArray = Java.to(anArray, "int[]")
print(javaIntArray[0]) // prints 1
print(javaIntArray[1]) // prints 13, as string "13" was converted to number 13 as per ECMAScript ToNumber conversion
print(javaIntArray[2]) // prints 0, as boolean false was converted to number 0 as per ECMAScript ToNumber conversion
</code></pre>
<p>
You can use either a string or a type object returned from <code>Java.type()</code> to specify the type of the array.
You can also omit the array type, in which case a <code>Object[]</code> will be created.
</p>
<p>
Given a Java array or Collection, <code>Java.from</code> returns a JavaScript array with a shallow copy of its contents. Note that in most cases, you can use Java arrays and lists natively in Nashorn; in cases where for some reason you need to have an actual JavaScript native array (e.g. to work with the array comprehensions functions), you will want to use this method.
</p>
<pre><code>
var File = Java.type("java.io.File");
var listCurDir = new File(".").listFiles();
var jsList = Java.from(listCurDir);
print(jsList);
</code></pre>
<hr>
<a name="jsimplement" id="jsimplement"></a>
<h3>Implementing Java interfaces</h3>
<p>A Java interface can be implemented in JavaScript by using a
Java anonymous class-like syntax:</p>
<pre><code>
// <a href="source/runnable.js">runnable.js</a>
var r = new java.lang.Runnable() {
run: function() {
print("running...\n");
}
};
// "r" can be passed to Java methods that expect java.lang.Runnable
var th = new java.lang.Thread(r);
th.start();
th.join();
</code>
</pre>
<p>When an interface with a single method is expected, you can pass
a script function directly.(auto conversion)</p>
<pre><code>
// <a href="source/samfunc.js">samfunc.js</a>
function func() {
print("I am func!");
}
// pass script function for java.lang.Runnable argument
var th = new java.lang.Thread(func);
th.start();
th.join();
</code>
</pre>
<hr>
<a name="jsextendabstract" id="jsextendabstract"></a>
<h3>Extending Abstract Java Classes</h3>
<p>
If a Java class is abstract, you can instantiate an anonymous subclass of it using an argument list that is applicable to any of its public or protected constructors, but inserting a JavaScript object with functions properties that provide JavaScript implementations of the abstract methods. If method names are overloaded, the JavaScript function will provide implementation for all overloads. E.g.:
</p>
<pre><code>
var TimerTask = Java.type("java.util.TimerTask")
var task = new TimerTask({ run: function() { print("Hello World!") } })
</code></pre>
Nashorn supports a syntactic extension where a "new" expression followed by an argument is identical to invoking the constructor and passing the argument to it, so you can write the above example also as:
<pre><code>
var task = new TimerTask {
run: function() {
print("Hello World!")
}
}
</code></pre>
which is very similar to Java anonymous inner class definition. On the other hand, if the type is an abstract type with a single abstract method (commonly referred to as a "SAM type") or all abstract methods it has share the same overloaded name), then instead of an object, you can just pass a function, so the above example can become even more simplified to:
<pre><code>
var task = new TimerTask(function() { print("Hello World!") })
</code></pre>
<p>
Note that in every one of these cases if you are trying to instantiate an abstract class that has constructors that take some arguments, you can invoke those simply by specifying the arguments after the initial implementation object or function.
</p>
<p>
The use of functions can be taken even further; if you are invoking a Java method that takes a SAM type, you can just pass in a function object, and Nashorn will know what you meant:
</p>
<code><pre>
Java.type("java.util.Timer")
timer.schedule(function() { print("Hello World!") })
</code></pre>
Here, <code>Timer.schedule()</code> expects a <code>TimerTask</code> as its argument, so Nashorn creates an instance of a TimerTask subclass and uses the passed function to implement its only abstract method, run(). In this usage though, you can't use non-default constructors; the type must be either an interface, or must have a protected or public no-arg constructor.
<hr>
<a name="jsextendconcrete" id="jsextendconcrete"></a>
<h3>Extending Concrete Java Classes</h3>
<p>
To extend a concrete Java class, you have to use <code>Java.extend</code> function.
<code>Java.extend</code> returns a type object for a subclass of the specified Java class (or implementation of the specified interface) that acts as a script-to-Java adapter for it.
</p>
<pre><code>
// <a href="source/javaextend.js">javaextend.js</a>
var ArrayList = Java.type("java.util.ArrayList")
var ArrayListExtender = Java.extend(ArrayList)
var printSizeInvokedArrayList = new ArrayListExtender() {
size: function() { print("size invoked!"); }
}
var printAddInvokedArrayList = new ArrayListExtender() {
add: function(x, y) {
if(typeof(y) === "undefined") {
print("add(e) invoked!");
} else {
print("add(i, e) invoked!");
}
}
};
printSizeInvokedArrayList.size();
printAddInvokedArrayList.add(33, 33);
</code></pre>
<p>
The reason you must use <code>Java.extend()</code> with concrete classes is that with concrete classes, there can be a
syntactic ambiguity if you just invoke their constructor. Consider this example:
</p>
<pre><code>
var t = new java.lang.Thread({ run: function() { print("Hello!") } })
</code></pre>
<p>
If we allowed subclassing of concrete classes with constructor syntax, Nashorn couldn't tell if you're creating a new
<code>Thread</code> and passing it a <code>Runnable</code> at this point, or you are subclassing <code>Thread</code> and
passing it a new implementation for its own <code>run()</code> method.
</p>
<hr>
<a name="jsimplementmultiple" id="jsimplementmultiple"></a>
<h3>Implementing Multiple Interfaces</h3>
<p>
<code>Java.extend</code> can in fact take a list of multiple types. At most one of the types can be a class, and the rest must
be interfaces (the class doesn't have to be the first in the list). You will get back an object that extends the class and
implements all the interfaces. (Obviously, if you only specify interfaces and no class, the object will extend <code>java.lang.Object</code>).
<hr>
<a name="classBoundImplementations" id="classBoundImplementations"></a>
<h3>Class-Bound Implementations</h3>
<p>
The methods shown so far for extending Java classes and implementing interfaces &ndash; passing an implementation JavaScript object
or function to a constructor, or using <code>Java.extend</code> with <code>new</code> &ndash; all produce classes that take an
extra JavaScript object parameter in their constructors that specifies the implementation. The implementation is therefore always bound
to the actual instance being created with <code>new</code>, and not to the whole class. This has some advantages, for example in the
memory footprint of the runtime, as Nashorn can just create a single "universal adapter" for every combination of types being implemented.
In reality, the below code shows that different instantiations of, say, <code>Runnable</code> have the same class regardless of them having
different JavaScript implementation objects:
</p>
<pre><code>
var Runnable = java.lang.Runnable;
var r1 = new Runnable(function() { print("I'm runnable 1!") })
var r2 = new Runnable(function() { print("I'm runnable 2!") })
r1.run()
r2.run()
print("We share the same class: " + (r1.class === r2.class))
</code></pre>
<p>
prints:
</p>
<pre><code>
I'm runnable 1!
I'm runnable 2!
We share the same class: true
</code></pre>
<p>
Sometimes, however, you'll want to extend a Java class or implement an interface with implementation bound to the class, not to
its instances. Such a need arises, for example, when you need to pass the class for instantiation to an external API; prime example
of this is the JavaFX framework where you need to pass an Application class to the FX API and let it instantiate it.
</p>
<p>
Fortunately, there's a solution for that: <code>Java.extend()</code> &ndash; aside from being able to take any number of type parameters
denoting a class to extend and interfaces to implement &ndash; can also take one last argument that has to be a JavaScript object
that serves as the implementation for the methods. In this case, <code>Java.extend()</code> will create a class that has the same
constructors as the original class had, as they don't need to take an an extra implementation object parameter. The example below
shows how you can create class-bound implementations, and shows that in this case, the implementation classes for different invocations
are indeed different:
</p>
<pre><code>
var RunnableImpl1 = Java.extend(java.lang.Runnable, function() { print("I'm runnable 1!") })
var RunnableImpl2 = Java.extend(java.lang.Runnable, function() { print("I'm runnable 2!") })
var r1 = new RunnableImpl1()
var r2 = new RunnableImpl2()
r1.run()
r2.run()
print("We share the same class: " + (r1.class === r2.class))
</code></pre>
<p>
prints:
</p>
<pre><code>
I'm runnable 1!
I'm runnable 2!
We share the same class: false
</code></pre>
<p>
As you can see, the major difference here is that we moved the implementation object into the invocation of <code>Java.extend</code>
from the constructor invocations &ndash; indeed the constructor invocations now don't even need to take an extra parameter! Since
the implementations are bound to a class, the two classes obviously can't be the same, and we indeed see that the two runnables no
longer share the same class &ndash; every invocation of <code>Java.extend()</code> with a class-specific implementation object triggers
the creation of a new Java adapter class.
</p>
<p>
Finally, the adapter classes with class-bound implementations can <i>still</i> take an additional constructor parameter to further
override the behavior on a per-instance basis. Thus, you can even combine the two approaches: you can provide part of the implementation
in a class-based JavaScript implementation object passed to <code>Java.extend</code>, and part in another object passed to the constructor.
Whatever functions are provided by the constructor-passed object will override the functions in the class-bound object.
</p>
<pre><code>
var RunnableImpl = Java.extend(java.lang.Runnable, function() { print("I'm runnable 1!") })
var r1 = new RunnableImpl()
var r2 = new RunnableImpl(function() { print("I'm runnable 2!") })
r1.run()
r2.run()
print("We share the same class: " + (r1.class === r2.class))
</code></pre>
<p>
prints:
</p>
<pre><code>
I'm runnable 1!
I'm runnable 2!
We share the same class: true
</code></pre>
<hr>
<a name="jsoverload" id="jsoverload"></a>
<h3>Overload Resolution</h3>
<p>Java methods can be overloaded by argument types. In Java,
overload resolution occurs at compile time (performed by javac).
When calling Java methods from Nashorn, the appropriate method will be
selected based on the argument types at invocation time. You do not need
to do anything special &ndash; the correct Java method overload variant
is selected based automatically. You still have the option of explicitly
specifying a particular overload variant. Reasons for this include
either running into a genuine ambiguity with actual argument types, or
rarely reasons of performance &ndash; if you specify the actual overload
then the engine doesn't have to perform resolution during invocation.
Individual overloads of a Java methods are exposed as special properties
with the name of the method followed with its signature in parentheses.
You can invoke them like this:</p>
<pre><code>
// <a href="source/overload.js">overload.js</a>
var out = java.lang.System.out;
// select a particular print function
out["println(Object)"]("hello");
</code>
</pre>
<p>
Note that you normally don't even have to use qualified class names in
the signatures as long as the unqualified name of the type is sufficient
for uniquely identifying the signature. In practice this means that only
in the extremely unlikely case that two overloads only differ in
parameter types that have identical unqualified names but come from
different packages would you need to use the fully qualified name of the
class.
</p>

<a name="dataTypeMapping" id="dataTypeMapping"></a>
<h3>Mapping of Data Types Between Java and JavaScript</h3>
<p>
We have previously shown some of the data type mappings between Java and JavaScript.
We saw that arrays need to be explicitly converted. We have also shown that JavaScript functions
are automatically converted to SAM types when passed as parameters to Java methods. Most other
conversions work as you would expect.
</p>
<p>
Every JavaScript object is also a <code>java.util.Map</code> so APIs receiving maps will receive them directly.
</p>
<p>
When numbers are passed to a Java API, they will be converted to the expected target numeric type, either boxed or
primitive, but if the target type is less specific, say <code>Number</code> or <code>Object</code>, you can only
count on them being a <code>Number</code>, and have to test specifically for whether it's a boxed <code>Double</code>,
<code>Integer</code>, <code>Long</code>, etc. &ndash; it can be any of these due to internal optimizations. Also, you
can pass any JavaScript value to a Java API expecting either a boxed or primitive number; the JavaScript specification's
<code>ToNumber</code> conversion algorithm will be applied to the value.
</p>
<p>
In a similar vein, if a Java method expects a <code>String</code> or a <code>Boolean</code>, the values will be
converted using all conversions allowed by the JavaScript specification's <code>ToString</code> and <code>ToBoolean</code>
conversions.
</p>
<p>
Finally, a word of caution about strings. Due to internal performance optimizations of string operations, JavaScript strings are
not always necessarily of type <code>java.lang.String</code>, but they will always be of type <code>java.lang.CharSequence</code>.
If you pass them to a Java method that expects a <code>java.lang.String</code> parameter, then you will naturally receive a Java
String, but if the signature of your method is more generic, i.e. it receives a <code>java.lang.Object</code> parameter, you can
end up with an object of private engine implementation class that implements <code>CharSequence</code> but is not a Java String.

<h2>Implementing Your Own Script Engine</h2>
<p>We will not cover implementation of JSR-223 compliant script

provides useful defaults for a few methods of the
