930f7e117d Suppress PHP 8 deprecation warning in __arcanist_init_script__
Summary:
As of PHP 8, the XML entity loader is disabled by default and the
libxml_disable_entity_loader function is deprecated. Thus suppress the
deprecation warning for now; we could skip the function call, but this
is safer.

Test Plan: Used to create this revision with PHP 8 on macOS

524aa2aed2 Fix "PhutilOpaqueEnvelopeTestCase" under PHP 7.4 with "zend.exception_ignore_args"
Summary:
See PHI1894. PHP 7.4 introduced a new runtime configuration option, "zend.exception_ignore_args", which removes the "args" from exception backtraces.

The "PhutilOpaqueEnvelopeTestCase" relies on this behavior (since it explicitly inspects stack frames). Although the test isn't critical and could be restructured, it seems like there is little value to ever enabling this option in the context of Phabricator.

Disable it at startup so environments are more consistent across different PHP versions and configurations.

Test Plan:
  - Enabled "zend.exception_ignore_args" under PHP 7.4.
  - Ran "PhutilOpaqueEnvelopeTestCase".
  - Before: failure, expected signpost value not present in stack trace (because no "args" are present on the exception).
  - After: test passes.

354da1ddaa When saving and restoring local state in Mercurial, also save and restore bookmarks
Summary:
Ref PHI1808. In Mercurial, we must save and restore bookmark state explicitly.

  - Save and restore bookmarks.
  - Clean up concepts in "arc-ls-markers" slightly, so we don't need separate "isCurrent" and "isActive" flags, hopefully.

I believe the totality of Mercurial state is:

  - A (non-bare) working copy points at exactly one commit (which might be the empty/null commit, in an empty repository).
  - A working copy has exactly one active branch.
    - Each branch has zero or more heads.
    - Each head may be closed.
    - Each (non-null) commit belongs to exactly one branch.
    - Note that the active branch may have zero heads and zero commits which belong to it!
  - A working copy has zero or one active bookmark.

To capture this, we now emit:

  - A list of branch heads. If a branch head is a working copy commit, that head is flagged as active.
  - A list of bookmarks. If a bookmark is the current bookmark, that bookmark is flagged as active.
  - A single "branch-state" virtual marker. This covers the case where you have run "hg branch X" to create X, but no objects in the working copy actually correspond to X yet. It also covers the case where you are on a concrete branch, but not any head of that branch.
  - A single "commit-state" virtual marker. This always shows the current commit in the working copy.

Test Plan:
  - Useful states to test are:
    - Empty repository (not all commands currently work here).
    - Normal repository, on a bookmark.
    - Normal repository, no bookmark.
    - "hg up 123" to update to somewhere in history.
    - "hg branch X", to start a new branch with no commits.
  - Ran "arc branches" and "arc bookmarks" in various states. Saw generally sensible output.
  - Ran "arc land --hold ..." in various states against a failing remote. Saw generally sensible output, and saw working properly restored to the original state.

41774ba9cc Fix additional Mercurial/Python compatibility issues in "arc land"
Summary:
Ref PHI1805. Under some combination of versions (Python 3.8?), "arc-ls-markers" is running into additional Python runtime issues.

Sprinkle more "b" around to resolve them? Also clean up a couple of plain "arc" issues.

Test Plan:
Landed a change in Mercurial.

Some of this works fine without changes in Python 3.7/2.7 against Mercurial 4.7/5.4, so this may not be exhaustive.

a28e76b7b3 Allow "hg arc-ls-markers" to run under Python 2 or Python 3
Summary:
Ref T13546. See PHI1805. Currently, the "arc-ls-markers" extension doesn't run under Python 3:

  - some stuff needs "b'...'" to mark it as a byte string;
  - "dict.iteritems()" is gone in Python 3, and "mercurial.pycompat" isn't always available;
  - in Python 3, "json" refuses to print byte strings; and
  - the compiler caching behavior in Python 3 has changed.

Try to get these things working in the same way under Python 2 and Python 3.

Test Plan:
Ran this command (with `python` as Python 2, locally):

```
$ python /usr/local/bin/hg --config 'extensions.arc-hg=/Users/epriestley/dev/core/lib/arcanist/support/hg/arc-hg.py' arc-ls-markers --
```

...and this command:

```
$ python3 /usr/local/bin/hg --config 'extensions.arc-hg=/Users/epriestley/dev/core/lib/arcanist/support/hg/arc-hg.py' arc-ls-markers --
```

..and saw the same output in both cases (previously, `python3 ...` fataled in various ways).

86951ad067 Use a "branchmap" call to identify remote branches in "arc-hg"
Summary:
Ref T9948. Ref T13546. To identify remote branch heads -- not just modified heads -- use "branchmap" like "hg outgoing" does.

I wasn't able to find any other way to get what we want: for example, with a bundlerepo, "peer.heads()" and "peer.changelog.heads()" include local branches which are not present in the remote.

It generally seems difficult (perhaps impossible?) to distinguish between these cases by using "getremotechanges()":

  - branch X exists at position Y in both the local and remote;
  - branch X exists at positino Y in the local, but not the remote.

In any case, this seems to work properly and //should// do less work than "getremotechanges()" since we don't need to pull as much data over the wire.

Test Plan: Ran "hg arc-ls-markers" in various repositories, got what appeared to be a faithful representation of the remote branch and bookmark state.

488a24c40a In "arc land" in Mercurial, inch closer to making complex branch/bookmark workflows function
Summary:
Ref T9948. Ref T13546. This change moves toward a functional "arc land" in Mercurial.

Because of how "bundlerepo.getremotechanges()" works, "hg arc-ls-markers" does not actually list markers in the remote that aren't different from local markers so it's hard to get anywhere with this.

Test Plan: Got somewhat-encouraging output from "arc land" and "hg arc-ls-markers", but too many things are still broken for this to really work yet.

b1f807f7ca Disambiguate various types of Mercurial remote markers with "hg arc-ls-remote"
Summary: Ref T13546. Ref T9948. It seems challenging to examine a remote in vanilla Mercurial. Provide an "hg arc-ls-remote" command which functions like "git ls-remote" so we can figure out if "--into X" is a bookmark, branch, both, neither, or a branch with multiple heads without mutating the working copy as a side effect.

Test Plan: Ran various "arc land --into ..." commands in a Mercurial working copy, saw apparently-sensible resolution of remote marker names.

a1ee2ab931 Fix improper XHPAST parsing of namespace grammar like "use x as private;"
Summary:
Depends on D21067. Ref T13492. Converting unit tests to be readable exposed this error in the grammar.

Normally, "grammar_rule" rules emit a standalone Node. In this case, the bottom-level grammar rule is a collection of trivial rules and the callers configure the Node. Wrap the bottom-level rule in a configuration rule so the node is configured correctly and consistently, in exactly one place.

Test Plan: Ran unit tests.

6d15c6ea48 Remove duplication of XHPAST version in PHP and C code
Summary:
Depends on D21063. Ref T13492. Currently, XHPAST defines a version in both PHP code and C code, and they must be kept in sync.

Switch to a single definition in PHP, then carry it through the build pipeline into C.

763ac445dc Revert xhpast changes that impacted builds under Bison 2.3
Summary:
Fixes T9753. Changes some time ago (in D13970 + D13974) improved XHPAST build compile-time warning behavior under Bison 3.

However, macOS still ships with Bison 2.3 and these changes prevent XHPAST from building with Bison 2.3. The changes didn't introduce version detection, so Bison 2.3 builds fail somewhat mysteriously without obvious next steps.

It's relatively easy to install Bison 3 on macOS via Homebrew, but the Bison 3 changes aren't terribly substantive and XHPAST doesn't actually depend on any Bison 3 features, so just return to Bison 2.3 for now.

It would be reasonable to undo this again and retarget Bison 3 in the future, but ideally we should wait until macOS ships with Bison 3 or we have a specific reason to bump the minimum required version to 3. If/when we do, we should version-detect Bison and raise a clear error message.

Test Plan: Built xhpast under Bison 2.3 on a default macOS install using "make cleanall && make install".

c471983697 Collapse Arcanist toolsets from "wilds" into "master", as an overlay layer
Summary:
Depends on D20988. Ref T13395. Ref T13098. Ref T13203.

This brings all the "toolsets" code into "master". We try to run commands as toolsets commands first, then fall back to older code.

Since the "toolsets" class tree is mostly parallel to the older class tree, this isn't completely broken. Currently, all commands fall back.

Test Plan: Created this diff, ran various other commands. But this is probably a long shot from finished.
