-## Getting Sources
-### macOS, Linux
+## Getting sources
+__OSX, Linux:__
 ```
 git config --global core.autocrlf input
 git clone git@github.com:JetBrains/JetBrainsRuntime.git
 ```

-### Windows
-<a name="sources-windows"></a>
+__Windows:__
 ```
 git config --global core.autocrlf false
 git clone git@github.com:JetBrains/JetBrainsRuntime.git
 ```

-## Configuring the Build Environment
-Here are quick per-platform instructions for those who can't wait to get started. 
-Please refer to [OpenJDK build docs](http://hg.openjdk.java.net/jdk/jdk11/raw-file/tip/doc/building.html) for in-depth
-coverage of all the details.
-
-> **_TIP:_**  To get a preliminary report of what's missing, run `./configure` and check its output. 
-> It would usually have a meaningful advice on how to solve the problem.
-
-### Linux (Docker)
-Create a container:
+# Configure Local Build Environment
+## Linux (docker)
 ```
 $ cd jb/project/docker
 $ docker build .
 ...
 Successfully built 942ea9900054
-```
-Run these commands in the new container:
-```
+
 $ docker run -v `pwd`../../../../:/JetBrainsRuntime -it 942ea9900054
+
 # cd /JetBrainsRuntime
 # sh ./configure
 # make images CONF=linux-x86_64-normal-server-release
+
 ```

-### Ubuntu Linux
-Install the necessary tools, libraries, and headers with:
-```
-$ sudo apt-get install autoconf make build-essential libx11-dev libxext-dev libxrender-dev libxtst-dev \
-       libxt-dev libxrandr-dev libcups2-dev libfontconfig1-dev libasound2-dev \
-       openjdk-11-jdk
-```
-Then run the following:
+## Linux (Ubuntu 18.10 desktop)
 ```
+$ sudo apt-get install autoconf make build-essential libx11-dev libxext-dev libxrender-dev libxtst-dev libxt-dev libxrandr-dev libcups2-dev libfontconfig1-dev libasound2-dev 
+
 $ cd JetBrainsRuntime
 $ sh ./configure --disable-warnings-as-errors
 $ make images
 ```

-### Windows
-<a name="build-windows"></a>
-Install the following:
-* [Cygwin x64](http://www.cygwin.com/).
-  Required packages: `autoconf`, `binutils`, `cpio`, `diffutils`, `file`, `gawk`, `gcc-core`, `make`, `m4`, `unzip`, `zip`.  
-  Install those together with Cygwin.
-* [Visual Studio compiler toolset](https://visualstudio.microsoft.com/downloads/).
-  Install with the desktop development kit, which includes Windows SDK and compilers.
-  Visual Studio 2015 is supported by default.
-* [Java 11](https://docs.aws.amazon.com/corretto/latest/corretto-11-ug/downloads-list.html). 
-  If you have problems while configuring, read [Java tips on Cygwin](http://horstmann.com/articles/cygwin-tips.html).
+## Windows
+#### TBD

-From the command line: 
-```
-"c:\Program Files (x86)\Microsoft Visual Studio 15.0\VC\vcvarsall.bat" amd64

-You can use  [CLion](https://www.jetbrains.com/clion/) to develop native parts of the JetBrains Runtime and
-[IntelliJ IDEA](https://www.jetbrains.com/idea/) for the parts written in Java.
-Both require projects to be created.
-
-### CLion
-Run
-```
-$ make compile-commands
-```
-in the git root and open the resulting `build/.../compile_commands.json` file as a project.
-Then use `Tools | Compilation Database | Change Project Root` to point to git root of this repository.

-### IDEA
-Run
-```
-$ sh ./bin/idea.sh
-```
-in the git root to generate project files (add `--help` for options). Then open the git root directory
-as a project in IDEA.

 <p>This requires a more complex setup and build procedure. This section assumes you are familiar with cross-compiling in general, and will only deal with the particularities of cross-compiling the JDK. If you are new to cross-compiling, please see the <a href="https://en.wikipedia.org/wiki/Cross_compiler#External_links">external links at Wikipedia</a> for a good start on reading materials.</p>
 <p>Cross-compiling the JDK requires you to be able to build both for the build platform and for the target platform. The reason for the former is that we need to build and execute tools during the build process, both native tools and Java tools.</p>
 <p>If all you want to do is to compile a 32-bit version, for the same OS, on a 64-bit machine, consider using <code>--with-target-bits=32</code> instead of doing a full-blown cross-compilation. (While this surely is possible, it's a lot more work and will take much longer to build.)</p>
-<h3 id="cross-compiling-the-easy-way-with-openjdk-devkits">Cross compiling the easy way with OpenJDK devkits</h3>
-<p>The OpenJDK build system provides out-of-the box support for creating and using so called devkits. A <code>devkit</code> is basically a collection of a cross-compiling toolchain and a sysroot environment which can easily be used together with the <code>--with-devkit</code> configure option to cross compile the OpenJDK. On Linux/x86_64, the following command:</p>
-<pre><code>bash configure --with-devkit=&lt;devkit-path&gt; --openjdk-target=ppc64-linux-gnu &amp;&amp; make</code></pre>
-<p>will configure and build OpenJDK for Linux/ppc64 assuming that <code>&lt;devkit-path&gt;</code> points to a Linux/x86_64 to Linux/ppc64 devkit.</p>
-<p>Devkits can be created from the <code>make/devkit</code> directory by executing:</p>
-<pre><code>make [ TARGETS=&quot;&lt;TARGET_TRIPLET&gt;+&quot; ] [ BASE_OS=&lt;OS&gt; ] [ BASE_OS_VERSION=&lt;VER&gt; ]</code></pre>
-<p>where <code>TARGETS</code> contains one or more <code>TARGET_TRIPLET</code>s of the form described in <a href="https://sourceware.org/autobook/autobook/autobook_17.html">section 3.4 of the GNU Autobook</a>. If no targets are given, a native toolchain for the current platform will be created. Currently, at least the following targets are known to work:</p>

If the base OS is &quot;Fedora&quot; the corresponding Fedora release can be specified with the help of the <code>BASE_OS_VERSION</code> option (with &quot;27&quot; as default version). If the build is successful, the new devkits can be found in the <code>build/devkit/result</code> subdirectory:</p>
-<pre><code>cd make/devkit
-make TARGETS=&quot;ppc64le-linux-gnu aarch64-linux-gnu&quot; BASE_OS=Fedora BASE_OS_VERSION=21

-<p>Notice that devkits are not only useful for targeting different build platforms. Because they contain the full build dependencies for a system (i.e. compiler and root file system), they can easily be used to build well-known, reliable and reproducible build environments. You can for example create and use a devkit with GCC 7.3 and a Fedora 12 sysroot environment (with glibc 2.11) on Ubuntu 14.04 (which doesn't have GCC 7.3 by default) to produce OpenJDK binaries which will run on all Linux systems with runtime libraries newer than the ones from Fedora 12 (e.g. Ubuntu 16.04, SLES 11 or RHEL 6).</p>

 <p>A common cross-compilation target is the ARM CPU. When building for ARM, it is useful to set the ABI profile. A number of pre-defined ABI profiles are available using <code>--with-abi-profile</code>: arm-vfp-sflt, arm-vfp-hflt, arm-sflt, armv5-vfp-sflt, armv6-vfp-hflt. Note that soft-float ABIs are no longer properly supported by the JDK.</p>
 <p>The JDK contains two different ports for the aarch64 platform, one is the original aarch64 port from the <a href="http://openjdk.java.net/projects/aarch64-port">AArch64 Port Project</a> and one is a 64-bit version of the Oracle contributed ARM port. When targeting aarch64, by the default the original aarch64 port is used. To select the Oracle ARM 64 port, use <code>--with-cpu-port=arm64</code>. Also set the corresponding value (<code>aarch64</code> or <code>arm64</code>) to --with-abi-profile, to ensure a consistent build.</p>

-### Cross compiling the easy way with OpenJDK devkits
-
-The OpenJDK build system provides out-of-the box support for creating and using
-so called devkits. A `devkit` is basically a collection of a cross-compiling
-toolchain and a sysroot environment which can easily be used together with the
-`--with-devkit` configure option to cross compile the OpenJDK. On Linux/x86_64,
-the following command:
-```
-bash configure --with-devkit=<devkit-path> --openjdk-target=ppc64-linux-gnu && make
-```
-
-will configure and build OpenJDK for Linux/ppc64 assuming that `<devkit-path>`
-points to a Linux/x86_64 to Linux/ppc64 devkit.
-
-Devkits can be created from the `make/devkit` directory by executing:
-```
-make [ TARGETS="<TARGET_TRIPLET>+" ] [ BASE_OS=<OS> ] [ BASE_OS_VERSION=<VER> ]
-```
-
-where `TARGETS` contains one or more `TARGET_TRIPLET`s of the form
-described in [section 3.4 of the GNU Autobook](
-https://sourceware.org/autobook/autobook/autobook_17.html). If no
-targets are given, a native toolchain for the current platform will be
-created. Currently, at least the following targets are known to work:
-
- Supported devkit targets
- ------------------------
- x86_64-linux-gnu
- aarch64-linux-gnu
- arm-linux-gnueabihf
- ppc64-linux-gnu
- ppc64le-linux-gnu
- s390x-linux-gnu
-
-`BASE_OS` must be one of "OEL6" for Oracle Enterprise Linux 6 or
-"Fedora" (if not specified "OEL6" will be the default). If the base OS
-is "Fedora" the corresponding Fedora release can be specified with the
-help of the `BASE_OS_VERSION` option (with "27" as default version).
-If the build is successful, the new devkits can be found in the
-`build/devkit/result` subdirectory:
-```
-cd make/devkit
-make TARGETS="ppc64le-linux-gnu aarch64-linux-gnu" BASE_OS=Fedora BASE_OS_VERSION=21
-ls -1 ../../build/devkit/result/
-x86_64-linux-gnu-to-aarch64-linux-gnu
-x86_64-linux-gnu-to-ppc64le-linux-gnu
-```
-
-Notice that devkits are not only useful for targeting different build
-platforms. Because they contain the full build dependencies for a
-system (i.e. compiler and root file system), they can easily be used
-to build well-known, reliable and reproducible build environments. You
-can for example create and use a devkit with GCC 7.3 and a Fedora 12
-sysroot environment (with glibc 2.11) on Ubuntu 14.04 (which doesn't
-have GCC 7.3 by default) to produce OpenJDK binaries which will run on
-all Linux systems with runtime libraries newer than the ones from
-Fedora 12 (e.g. Ubuntu 16.04, SLES 11 or RHEL 6).

-
-Fortunately, you can create sysroots for foreign architectures with tools
-provided by your OS. On Debian/Ubuntu systems, one could use `qemu-deboostrap` to

-  * Install cross-compiler on the *build* system:

 ## Hints and Suggestions for Advanced Users

+### Setting Up a Forest for Pushing Changes (defpath)
+
+To help you prepare a proper push path for a Mercurial repository, there exists
+a useful tool known as [defpath](
+http://openjdk.java.net/projects/code-tools/defpath). It will help you setup a
+proper push path for pushing changes to the JDK.
+
+Install the extension by cloning
+`http://hg.openjdk.java.net/code-tools/defpath` and updating your `.hgrc` file.
+Here's one way to do this:
+
+```
+cd ~
+mkdir hg-ext
+cd hg-ext
+hg clone http://hg.openjdk.java.net/code-tools/defpath
+cat << EOT >> ~/.hgrc
+[extensions]
+defpath=~/hg-ext/defpath/defpath.py
+EOT
+```
+
+You can now setup a proper push path using:
+```
+hg defpath -d -u <your OpenJDK username>
+```
+
+If you also have the `trees` extension installed in Mercurial, you will
+automatically get a `tdefpath` command, which is even more useful. By running
+`hg tdefpath -du <username>` in the top repository of your forest, all repos
+will get setup automatically. This is the recommended usage.
+

+### Learn About Mercurial
+
+To become an efficient JDK developer, it is recommended that you invest in
+learning Mercurial properly. Here are some links that can get you started:

-% IDE support in the JDK

-## Introduction
-
-When you are familiar with building and testing the JDK, you may want to
-configure an IDE to work with the source code. The instructions differ a bit
-depending on whether you are interested in working with the native (C/C++) or
-the Java code.
-
-### IDE support for native code
-
-There are a few ways to generate IDE configuration for the native sources,
-depending on which IDE to use.
-
-#### Visual Studio Code
-
-The make system can generate a [Visual Studio Code](https://code.visualstudio.com)
-workspace that has C/C++ source indexing configured correctly, as well as
-launcher targets for tests and the Java launcher. After configuring, a workspace
-for the configuration can be generated using:
-
-```shell
-make vscode-project
-```
-
-This creates a file called `jdk.code-workspace` in the build output folder. The
-full location will be printed after the workspace has been generated. To use it,
-choose `File -> Open Workspace...` in Visual Studio Code.
-
-##### Alternative indexers
-
-The main `vscode-project` target configures the default C++ support in Visual
-Studio Code. There are also other source indexers that can be installed, that
-may provide additional features. It's currently possible to generate
-configuration for two such indexers, [clangd](https://clang.llvm.org/extra/clangd/)
-and [rtags](https://github.com/Andersbakken/rtags). These can be configured by
-appending the name of the indexer to the make target, such as:
-
-```shell
-make vscode-project-clangd
-```
-
-Additional instructions for configuring the given indexer will be displayed
-after the workspace has been generated.
-
-#### Visual Studio
-
-This section is a work in progress.
-
-```shell
-make ide-project
-```
-
-#### Compilation Database
-
-The make system can generate generic native code indexing support in the form of
-a [Compilation Database](https://clang.llvm.org/docs/JSONCompilationDatabase.html)
-that can be used by many different IDEs and source code indexers.
-
-```shell
-make compile-commands
-```
-
-It's also possible to generate the Compilation Database for the HotSpot source
-code only, which is a bit faster as it includes less information.
-
-```shell
-make compile-commands-hotspot
-```
-
-### IDE support for Java code
-
-This section is a work in progress.

-Subject: [PATCH 05/33] HotswapAgent integration
-
-It include:
-
- option to compile DCEVM only version with -DDCEVM_ONLY added
-to CFLAGS (bash configure --with-extra-cflags="-DDCEVM_ONLY"), by
-default compilation goes with HotswapAgent
-
-Allow ha class initializer calls
-
-Add --add-opens for necessary modules/packages
- java.base/java.lang - for reflection access to Proxy.proxyCache
- java.base/jdk.internal.loader - for access proxyCache class
- java.desktop/java.beans - for reflection access to Introspector
- java.desktop/com.sun.beans
- java.base/java.io
- com.sun.beans.util
-
-Open jdk module to access ClassInfo.CACHE
-
- be quiet if HotswapAgent is not found in lib/, it is compatible with
-old DCEVM
- disable HotswapAgent for -Xshare:dump
- disable HotswapAgent in jvm tools
- disable HotswapAgent in keytool

-InstanceKlass in ClassLoaderData can be uninitialized when
-ClassLoaderDataGraph::classes_do is called. Using
-ClassLoaderDataGraph::dictionary_classes_do is safe but problem is still

- redefinition
-
-jdwp keeps relation class_ptr->class_ref in jvmti tag. class_ptr is used
-as a tag key, tag value is refnode. There are new class_ptrs after
-redefinition, therefore jdwp redefinition method update all affected
-keys in the tag map.

-Subject: [PATCH 32/33] JBR-3937 Fix crashes in C1/C2 compilers
-
-There is a race condition in enhanced redefinition with C1/C2. Therefore
-the patch stops C1/C2 compilation before redefinition and release after
-redefinition finishing. There is no performance impact since dcevm
-flushes all code cache.
