Summary:
Ref T13507. Currently, this function is a bit conservative about what it encodes, and passing it a string of binary garbage may result in an output which is not valid UTF8.
This could be refined somewhat, since it's less than ideal if the input has valid UTF8. The ideal behavior for byte sequences where all bytes are larger than 0x7F is probably a variation of "phutil_utf8ize()" that replaces bytes with "<0xXX>" instead of the Unicode error glyph.
For now, just err on the side of mangling.

Summary:
Ref T13490. "ExecFuture" can raise a "CommandException" when the subprocess fails. In most cases, this is desirable, since we usually do not expect subprocesses to fail.
Currently, "execx()" (which raises these exceptions) is the synchronous default (with the more verbose "exec_manual()" as an alternative if you expect the command may return an error code), but the Future variation has no way to hint that external resolution should raise an exception if the process exits with an error.
Since the "HardpointEngine" yield construct can resolve external futures, add a mode for this to simplify implementing "HardpointQuery" classes a bit. Without this, they either need to retain "$futures" and manually call "resolvex()", or check the "$err" result and throw some other exception, both of which are low-value boilerplate (queries that want to do this still can, of course).
This is basically like providing a hint that the futures should be resolved with "resolvex()" instead of "resolve()".
Also, make this the default behavior of a new "$api->newFuture()" wrapper.
Test Plan: Intentionally broke a command in a HardpointQuery, got a sensible exception automatically during external future resolution.

- "getWorkingCopy()" now returns a modern object (a "WorkingCopy").
- "getWorkingCopyIdentity()" now returns an older object (a "WorkingCopyIdentity").

Summary:
Depends on D21071. Ref T11968. Currently, "ConduitEngine" tries to lightly parallelize futures. This was a compromise when the initial "hardpoint" change didn't plan to pursue real request paralleization.
Now that the newer hardpoint change does, we don't need onboard resolution in ConduitEngine. Throw it away.
When the engine is supposed to resolve a future, it now just resolves that future on its own. This should be functionally identical to the previous behavior, except that it may be slower.
(In practice, because HTTP futures are backed by an internal cURL request pool, this proably has little effect anywhere. Moving to modern hardpoints will make performance no worse than it was prior to this change, in any case.)

Summary:
Ref T11968.
- Allow "WorkingCopy" objects to maintain an API object and update callers ("get...()" instead of "new...()").
- Always generate a WorkingCopy object and a RepositoryAPI object.
Currently, code has to look like this:
```
$working_copy = ...
if ($working_copy) {
$repository_api = ...
if ($repository_api [instanceof ... ]) {
```
This is clunky. There's also no reason some "arc" commands can't run outside a VCS working directory without special-casing how they interact with the filesystem.
Conceptually, model the filesystem as a trivial VCS (which stores exactly one commit, always amends onto it, and discards history). Provide a trivial WorkingCopy and API for it.
(This change isn't terribly interesting on its own, but chips away at landing the new Hardpoint infrastructure.)

Summary:
Ref T11968. "FutureIterator" recently became non-rewindable, and starting a Future twice is now an error.
This complicates a handful of use cases where a mostly-constant pool of futures is maintained over a long period of time, notably in daemon overseers and repository pull daemons.
They previously relied on being able to do "new FutureIterator($futures)" to continue resolution of a list of futures from any state. This no longer works quite like it used to, since Futures generally may not belong to more than one iterator now (and this property is desirable).
Introduce "FuturePool", which maintains exactly one iterator but manages the small amount of glue around adding and removing Futures from it, destroying it if the pool empties, and rebuilding it if the pool fills.
Test Plan: See next change, which makes use of this.

Summary:
Fixes T13504. This fixes three issues:
# In ExecFuture, "proc_open()" on an invalid binary could fail with an unconditional exception.
# In ExecPassthru, "proc_open()" on an invalid binary could fail with an unconditional exception.
# In "arc browse", "start <url>" does not work when the shell is bypassed.
In (1) and (2), the desired behavior is to fail with an exit code which is sometimes upgraded to an exception depending on calling convention.
Issue (1) most commonly manifested as "find" failing when run via "cmd.exe".
Issue (2) most commonly manifested as "arc browse" failing.
Issue (3) was entangled with issue (2).
In cases (1) and (2), assume "proc_open()" failures under Windows are because of bad binaries and treat them like bogus commands on Linux/Mac.
In case (3), use "cmd /c start" instead of "start" as a default browser on Windows.
Test Plan:
- On Windows, did mime type detection in cmd.exe. Before patch: proc_open() exception in "find". After patch: clean (albeit not terribly useful) detection.
- On Windows, did "arc browse ...". Before patch: proc_open() exception in "start". After patch: clean browser execution.

Summary:
Ref T13499. Currently, we throw most language errors as exceptions, but this list isn't exhaustive and errors we don't specifically make more severe are allowed to slip through.
This is generally undesirable, particularly in the case of "Undefined index:" errors. See T13499 for a specific case where this caused behavior to be more difficult to understand and diagnose than it should have been.
Make this the default behavior instead, except for "E_USER" errors, which we never expect to arise from first-party code.
This may be slightly too aggressive, but future changes can selectively reduce the severity of some types of errors if problems arise.
Test Plan:
- Executed code which intentionally accessed an undefined index, got an exception.

Summary:
Depends on D21031. Ref T11968. This clears some lint with the word "Future", but is just a minor cleanup patch not really related to the main goal in that task.
We currently warn on `preg_quote()` with no second parameter, but this is valid and correct:
```
preg_match('('.preg_quote($x).')', ...)
```
This is the modern recommended style for this sort of expression, so the warning is often a false positive; drop it.
The "__CLASS__" warning looks for hard-coded class names in strings, but currently looks for them as a word anywhere in the string.
This is often a false positive and sometimes makes error messages or exceptions untranslatable. For example, translators can't do anything with this:
> Filesystem path "%s" does not exist.
...if it's written as:
> %s path "%s" does not exist.
...just because it happens to appear in the class "Filesystem". Some other classes, including "Future", suffer from this.
Even when the detection is correct, it's clunky and a mistake here (failing to update the class name in an error message) is unlikely to ever do any real damage.
Test Plan: Ran unit tests and `arc lint`.

Summary:
See PHI1663. If "phabricator.uri" is not configured, we try to fall back to "default", but doesn't have a modern config specification and fails.
Instead, read "default" as a raw config value to preserve compatible behavior. My intent is to eventually remove it.
Test Plan:
In a directory with no "phabricator.uri" config available, ran `echo {} | arc call-conduit conduit.ping`. After the patch, got a reasonable error instead of a fatal.
In a directory with "default" configured but not "phabricator.uri", ran the same command. After the patch, got a ping.

Summary: Ref T13490. This largely makes "arc upload" work, although the Future stuff is still a bit wonky. See T11968.
Test Plan: Ran "arc upload README.md", got an upload.

Differential Revision: https://secure.phabricator.com/D21030
Summary: Ref T13490. This fixes one bug in D21025 (loading relative to "arcanist/" rather than the parent directory) and improves behavior when a library fails to load (we prompt the user to continue).
Test Plan:
- Ran `arc list` with bad library specifications, got a sensible error and an option to continue.
- Ran `arc list` with a library specification that existed next to "arcanist/", got a library load instead of an error.
Maniphest Tasks: T13490
Differential Revision: https://secure.phabricator.com/D21029
Summary: Ref T13490. This makes the "phage" toolset work properly and updates external library behavior to match the "classic" behavior, except that "--library" is now supported.
Test Plan: Ran "phage remote" workflows.

Summary:
Ref T13490. There's one simple "implode()" order issue here, and one slightly more complex one that uses "DIRECTORY_SEPARATOR" as glue.
Add test coverage for this, update the lint check to detect constants used as glue, and fix the callsites.
Test Plan:
- Added a failing test and made it pass.
- Ran `arc lint --everything` and looked for remaining implode warnings, found none.
Maniphest Tasks: T13490
Differential Revision: https://secure.phabricator.com/D21024
Summary: Ref T13490. Allows "arc upgrade" to run through the new Toolsets infrastructure.
Test Plan: Ran "arc upgrade", although you can't upgrade feature branches so this can't be entirely tested until it hits "master".
Maniphest Tasks: T13490
Differential Revision: https://secure.phabricator.com/D21006
Summary: Depends on D21004. Ref T13490. The "wilds" branch removed a bunch of dead features but some of them were resurrected by the merge. I don't think any of these are desirable to retain, so purge them all again, even in classic mode.
Test Plan: Grepped for affected symbols.

Summary:
Depends on D21001. Ref T13490.
- Require "--" to terminate arguments when running noninteractively.
- Don't correct spelling when running noninteractively (we still suggest corrections).
- Remove old "phage" wrapper script.
- Fix an issue where "argv" could implicitly generate a parseable "--argv" flag.
- Accept "--" as an argument terminator even when there is no argument list.
- Update some strings to use more modern quoting style.
- Make workflows decline to handle signals by default.
- Allow "arc weld" to weld non-UTF8 files together.
Test Plan: Ran various commands. Welded non-UTF8 files.

Summary: Depends on D20996. Ref T13395. Ports the updated version of this workflow from "experimental".
Test Plan: Ran `arc shell-complete` to install the hook, then shell-completed commands.

Summary: Depends on D20993. Ref T13395. Merges the more-modern "alias" out of "experimental".
Test Plan: Defined and invoked aliases. This has some rough edges: notably, no easy list/delete flow.

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.

- Merge a UTF8 fix for "cmd.exe" on Windows.
- Merge minor changes to JSON linters.
- Merge some shell completion stuff.
- Merge some "arc anoid" fixes.
- Merge various Windows improvements to unit tests which interact with processes / the filesystem.

- Merge a UTF8 character class fix.
- Merge script initialization.
- Merge unit test support scripts.
- Merge some initialization code.
- Merge Windows stdout/stderr-as-files code.
- Merge a bunch of code for making exec tests work on Windows.
- Merge more Windows unit test fixes.
- Merge "continue on failure" mode when loading symbols.

Summary:
Depends on D20986. Ref T13395. This //mostly// collapses the entire "experimental" branch into "master".
I plan to change the "Ref/Hardpoint" pattern to become future oriented, but this is more steps forward than sideways.

Summary: Ref T13481. Some older versions of Git appear to not support "--" in these commands. Just drop it. This can lead to ambiguous results with certain obviously-silly remote names, but doesn't appear to lead to anything dangerous.

Summary: Fixes T13481. When identifying the URI for a remote, fall back from "git remote get-url" to "git ls-remote --get-url" to "git config remote.<name>.url" based on command output and version tests.
Test Plan: Ran `arc land --hold`, rigged the subcommands to fail to try all three fallbacks, ran `arc land --hold --remote asdfasdf` to get an explicit failure.

Differential Revision: https://secure.phabricator.com/D20950
Summary: Fixes T13458. Emit an explicit message when "arc close-revision --finalize" bails out because the revision is not "Accepted".
Test Plan: Ran `arc close-revision [--finalize] ...` on various revisions, saw more clear messaging.
Maniphest Tasks: T13458
Differential Revision: https://secure.phabricator.com/D20915
Summary:
Ref T13432. Git has a "diff.suppressBlankEmpty" config option which makes it emit nonstandard diffs with trimmed trailing whitespace on unchanged blank lines.
Currently, we don't parse these diffs correctly. Even if we do in the future, emitting a more standard diff is desirable.
Explicitly disable this option when executing "git diff" so we build more standard diffs.
Test Plan:
- Configured this option.
- Modified a file with a blank line in it without changing the blank line, got this goofy display diff:
{F6985234}
- Applied patch, rediffed the same change, saw "-c diff.suppressBlankEmpty" in "--trace" output and got this sensible diff:
{F6985235}

Differential Revision: https://secure.phabricator.com/D20877
Summary: Ref T13434. Since "git p4 submit" gets more complicated when submitting merges, and empty merges (as with "--no-ff") seem to vanish, and it's not clear this is desirable or useful anyway, just make the "merge" strategy an explicit error with Perforce remotes.
Test Plan: Ran "arc land --merge ..." in a Git/Perforce repository, got an explicit error. Ran "arc land --squash ...", got existing working behavior.

Differential Revision: https://secure.phabricator.com/D20871
Summary:
Fixes T10650. It's valid to `arc land --remote origin --onto master` without first fetching that ref. If we can't find a local ref for a specified remote branch, try to fetch it before giving up.
(In the long run, this should be valid even if the remote branch does not exist at all and the user intends to create it -- see T12876 -- but this is a step toward that.)
Test Plan:
- Ran `rm .git/refs/remotes/origin/master`, then landed into "master".
- Before: "arc land" bailed out immediately.
- After: "arc land" fetches the missing ref.
```
$ arc land
TARGET Landing onto "master", the default target under git.
REMOTE Using remote "origin", the default remote under Git.
TARGET No local ref exists for branch "master" in remote "origin", attempting fetch...
FETCHED Fetched branch "master" from remote "origin".

Summary:
Ref T13428. Historically, "implode()" accepts arguments in either order. PHP 7.4+ warns about glue not being first.
Add a lint check when the second parameter is a static scalar, implying it is the glue parameter.
Test Plan: Ran unit tests. See next change.
Maniphest Tasks: T13428
Differential Revision: https://secure.phabricator.com/D20857
Summary:
Fixes T10321. Some reasonable but less-common workflows involve running `arc land` from a detached HEAD state.
When users do this, we currently try to delete the raw hash as though it were a branch during cleanup. Instead, detect if the thing we're thinking about deleting is a branch or not, and just leave it alone if it isn't.
Test Plan:
- Ran `git checkout <some hash>`, then `arc land --revision <some revision>`.
- Before, everything worked but cleanup tried to `git branch -D <some hash>`.
- After, everything worked and cleanup skipped branch deletion.
Maniphest Tasks: T10321
Differential Revision: https://secure.phabricator.com/D20786
Summary:
The current code assumes git-svn is always working from a remote called
`trunk`, but if the repository is initialized without the `-T` option it
will instead be called `git-svn`, and if `--prefix` is used (which is
set by default to `origin/` in Git 2+) the remote name will have the
specified prefix as well.
Instead, look at the `fetch` target refspec set in the git-svn config.
Fixes T13293.
Test Plan:
`arc land` without errors (or manually creating a `trunk` branch) from a
checkout made with Git 2.18.0 (verified this manually on a non-`-T`
checkout as well).

Summary:
Fixes T6854. The current format for `lint-test` files is somewhat inflexible and does not allow us to make assertions regarding the code or name of the linter messages (of class `ArcanistLintMessage`) that are raised. Specifically, the `${severity}:${line}:${char}` format is hardcoded in `ArcanistLinterTestCase`. In this diff, I extend the this format to achieve the following goals:
- Allow for the lint message code and name to be specified. Specifically, the full format is `${severity}:${line}:${char}:${code}:${name}`.
- Make all fields optional. `error:3:` will match any and all errors occuring on line 3.
- Provide more useful output when assertions fail. Specifically, output //all// lint messages that are missing and/or surplus. Previously, only the first lint message was output.

Summary:
I am writing a proxy linter that can be used to wrap any `ArcanistExternalLinter` and execute all commands within a Docker container (see [[https://github.com/freelancer/flarc/blob/master/src/lint/linter/ArcanistDockerContainerLinterProxy.php |`ArcanistDockerContainerLinterProxy`]] from [[https://github.com/freelancer/flarc | `flarc`]]). In order for `ArcanistDockerContainerLinterProxy` to behave like the `ArcanistExternalLinter` that is being proxied, `final` needs to be removed from some methods.
I figured this was reasonable to submit upstream as a similar change ({D19630}) was previously accepted.
