 ```

-## Developing
-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.
-
-See also this detailed step-by-step tutorial for all platforms:
-[How to develop OpenJDK with CLion](https://blog.jetbrains.com/clion/2020/03/openjdk-with-clion/).
-
-### 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.

This means that whenever you add or update a package in Cygwin, you might (inadvertently) update tools that are used by the JDK build process, and that can cause unexpected build problems.</p>

 ## 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.

-Subject: [PATCH 28/33] JBR-3459: Fix race condition in
- ClassLoaderDataGraph::classes_do
-
-InstanceKlass in ClassLoaderData can be uninitialized when
-ClassLoaderDataGraph::classes_do is called. Using
-ClassLoaderDataGraph::dictionary_classes_do is safe but problem is still
-persisting with anonymous classes.

-Subject: [PATCH 29/33] JBR-3867 - update keys of jvmti TAG map after
- 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.

+# Vanessa Ogle, The Global Transformation of Time, 1870-1950 (2015), p 33,
+# writes "In 1919, the Gold Coast (Ghana as of 1957) made Greenwich
+# time its legal time and simultaneously legalized a summer time of
+# UTC - 00:20 minutes from March to October."; a footnote lists
+# the ordinance as being dated 1919-11-24.
+# The Crown Colonist, Volume 12 (1942), p 176, says "the Government
+# intend advancing Gold Coast time half an hour ahead of G.M.T.
+# The actual date of the alteration has not yet been announced."
+# These sources are incomplete and contradictory.  Possibly what is
+# now Ghana observed different DST regimes in different years.  For
+# lack of better info, use Shanks except treat the minus sign as a

-# Several of the midnight transitions mentioned above are ambiguous;
-# are they 00:00, 00:00s, 24:00, or 24:00s?  When resolving these ambiguities,
-# try to minimize changes from previous tzdb versions, for lack of better info.
-# Commentary from previous versions is included below, to help explain this.

-# Standard Time Declaration Order 2015 (L.N. 15/2015)

-# Standard Time Declaration Order 2017 (L.N. 31/2017)
-# http://online.fliphtml5.com/fizd/dmcu/#p=2
-#
-# From Tim Parenti (2020-12-05):
-# Although L.N. 31/2017 reads that it "shall come into operation at 2:00 a.m.
-# on 11th March 2018", a precise interpretation here poses some problems.  The
-# order states that "the standard time to be observed throughout the Turks and
-# Caicos Islands shall be the same time zone as the Eastern United States of
-# America" and further clarifies "[f]or the avoidance of doubt" that it
-# "applies to the Eastern Standard Time as well as any changes thereto for
-# Daylight Saving Time."  However, as clocks in Turks and Caicos approached
-# 02:00 -04, and thus the declared implementation time, it was still 01:00 EST
-# (-05), as DST in the Eastern US would not start until an hour later.
-#
-# Since it is unlikely that those on the islands switched their clocks twice in
-# the span of an hour, we assume instead that the adoption of EDT actually took
-# effect once clocks in the Eastern US had sprung forward, from 03:00 -04.
-# This discrepancy only affects the time zone abbreviation and DST flag for the
-# intervening hour, not wall clock times, as -04 was maintained throughout.
