Summary:
Ref T13675. Ref T13556. The "STDOUT" and "STDERR" constants are defined by the PHP CLI SAPI, in `cli_register_file_handles()`.
The "native arc" embedded PHP wrapper doesn't define these, and there's no real reason to define them, since they're just defined in terms of the PHP stream wrappers ("php://stdin", etc) anyway.
This patch isn't exhaustive (and a subsequent change should add lint, rejecting these magic constants) but is just trying to make native `arc` functional.
Test Plan: Created this revision with a standalone native `arc` binary.

In the update to D21716 the `str_starts_with` function was added which is only available in PHP 8. This changes it to use `strncmp()` which is compatible back to PHP 4.
Additionally fixed running into an error when trying to run `arc amend` on a commit which already matches the content known in Phabricator. Mercurial throws an error when running `amend` without file changes and using the exact same commit message it already has.
Test Plan:
I created a commit and revision then used `hg amend -e` to modify the commit message locally.
I used `arc amend` to update the commit message back to the appropriate message from Phabricator.
I ran `arc amend` again to verify that the command did not fail even though the commit message is unchanged.
I ran `arc inspect --explore -- 'commit(674492bb460)'` and verified it matched the appropriate commit, to verify the substring matching works properly.

Summary:
Ref T13666. Currently, "PhabricatorRepository->newConduitFuture()" sometimes returns a real "ConduitFuture" (when repository clustering is configured) and sometimes returns a degenerate "ImmediateFuture" (when repository clustering is not configured).
To populate the "ImmediateFuture", the Conduit method is called inline without any special exception handling. This means that the two pathways have significantly different exception behavior:
- On the "ImmediateFuture" pathway, the "newConduitFuture()" method itself may raise an exception related to resolving the call (e.g., invalid parameters).
- On the "ConduitFuture" pathway, exceptions are raised only once the future is "resolve()"'d.
The second behavior is the correct behavior (and the primary behavior of upstream test environments, since all my stuff and the Phacility stuff is clustered).
Prepare to put both pathways on the second behavior by introducing a "MethodCallFuture", which can move the `$conduit_call->execute()` call (and thus its exception handling) to future resolution time.
See also the followup diff in Phabricator to actually enact this change.

Summary:
Currently there are a number of `--config extensions.blah=` sprinkled throughout the Mercurial APIs which aren't pleasant to look at. Additionally it turns out the `rebase` command requires the `rebase` extension which is not turned on by default. Uses of `rebase` should also be including this flag to enable the extension when it's in use.
This adds `ArcanistMercurialAPI::buildMercurialExtensionCommand()` which allows running a Mercurial command that requires an extension just by naming the extension instead of providing the full `--config..` argument.
It can be used e.g.
```lang=php
$api->execxLocalWithExtension(
'strip',
'strip --rev %s --',
$rev);
$api->execxLocalWithExtension(
'arc-hg',
'arc-amend --logfile %s',
$tmp_file);
```
Which produces
```lang=console
$ hg --encoding utf-8 --config 'extensions.strip=' strip --rev 82567759e2d703e1e0497f5f41363de3a1500188 --

Summary:
After `arc diff` creates a revision in Phabricator it amends the commit to include a link to the revision in the commit message. For Mercurial this is done with `hg commit --amend --logfile` however this will fail when trying to create a diff for a non-head commit.
This updates `ArcanistMercurialAPI::amendCommit()` to allow amending a non-head commit in two ways, depending on whether `evolve` is in use:
No evolve:
1. Rebasing the current commit onto the current commit's parent, using the new commit message
2. Rebasing all children + descendants of the current commit onto the new resulting commit
3. Stripping the original commit
With evolve:
1. Amend the commit with `hg amend --logfile`
2. Run `hg evolve` to tidy up all commits
Test Plan:
I created 6 commits in a row placing a bookmark at commits 2 `bookmark1`, 4 `bookmark2`, and 6 `bookmark3`, and ensured I had `arc:bookmark` in my base ruleset.
No evolve, non-head changeset:
1. I verified I did not have `evolve` enabled by running `hg debugextensions` and did not see `evolve` in the listed active extensions.
2. I updated to `bookmark1` and modified a file to leave a dirty working state.
3. I ran `arc diff` and when prompted to amend my changes I said "yes", and verified a phab revision was created properly.
4. I checked the status of my repository and verified it was still linear and the bookmarks pointed to the proper commits.
5. I ran `hg log -r bookmark1 --template {desc}` to view the full commit message and verified it contained both `Summary: ...` and `Differential Revision: https://...`.
6. I ran `hg diff -c bookmark1` and verified the changes for that commit included the changes I made in step 2.
No evolve, head changeset:
1. I updated to `bookmark3` which is the head commit and modified a file to leave a dirty working state.
2. I ran `arc diff` and when prompted to amend my changes I said "yes", and verified a phab revision was created properly.
3. I checked the status of my repository and verified it was still linear and all the bookmarks pointed to the proper commits.
4. I ran `hg log -r bookmark3 --template {desc}` to view the full commit message and verified it contained both `Summary: ...` and `Differential Revision: https://...`.
5. I ran `hg diff -c bookmar3` and verified the changes for that commit included the changes I made in step 1.
With evolve:
1. I enabled `evolve` and verified it was enabled by running `hg debugextensions` and saw `evolve` in the listed active extensions.
2. I updated to `bookmark2` and modified a file to leave a dirty working state.
3. I ran `arc diff` and when prompted to amend my changes I said "yes", and verified a phab revision was created properly.

Summary:
Refs T13546
**Behavior Changes**
1. Currently, after landing the `--onto` bookmark will not be advanced to the newly pushed commit(s)
- This updates so that after pushing commits upstream, onto-marker bookmarks are pulled back from the server to retrieve their updated state
2. Currently, after landing the working directory will typically be the old `--onto` commit
- This updates the behavior in the following ways
1. If the starting working state is a commit that is part of a revision being landed, the post-land state will be the newly published commit for that revision
2. If the starting working state is a commit for a tip revision being landed and there is only a single `--onto` target, the post-land state will be the newly published commit and the `--onto` bookmark will be activated, if applicable. If there are multiple `--onto` targets defined (uncommon) then the resulting working state will be the same behavior as before, as the desired behavior for this case is ambiguous.
3. If the starting working state is a commit that is not part of any revision being landed, then the post-land state will be that same commit, activating the same previous bookmark if applicable.
**Bugs Fixed**
1. When landing a diff that includes multiple commits, where the non-tip commit adds a file and later commit modifies that file, the land process would fail during rebasing.
2. When landing, the display of what commits are going to be landed only includes the commit hash but should include part of the commit message for easy identification.
3. If errors occur during a rebase while landing, the resulting state is an in-progress rebase. Users will typically not be able to resolve this in-progress rebase and possibly confuse them further as they have to first abort the rebase before trying to clean up. These rebases will now be aborted by arcanist before exiting.
4. If using evolve, landing a non-tip revision would leave behind orphaned commits.
Test Plan:
Bookmark test
- I created a diff with bookmark `test`, as a branch from before the `master` commit
- I updated working state to activate `test`
- I landed that diff
- I verified that the resulting working state was on the newly published `master` commit
Non-bookmark test
- I created a diff with bookmark `test`, as a branch from before the `master` commit
- I updated working state to be the new commit, but not activate `test` even though it points to that same commit
- I landed that diff
- I verified that the resulting working state was on the newly published `master` commit
Not-working state test
- I created a diff with bookmark `test`, as a branch from before the `master` commit
- I updated working state to an older commit not related to the one being landed
- I landed that diff
- I verified the ending resulting working state was on the older commit I was on prior to landing
Multiple commits test
- Using `test` bookmark I created a commit that added a new file, made a diff, made another new commit on top of it which modified that file, then updated the diff
- I updated my working state to the first commit for the diff (non-head)
- I ran `arc land test` to land the diff
- I verified that the resulting working state was on the newly published `master` commit
Landing while on `master`
- I created a diff with a bookmark `test`, as a branch from before the `master` commit
- I updated working state to the `master` bookmark
- I landed that diff
- I verified that the resulting working state was on the newly published `master` commit
Landing with no local `master` bookmark
- I created a diff consisting of two commits with bookmark `test`, as a branch from before the `master` commit
- I left working state on `test` and deleted my local `master` bookmark
- I landed that diff
- I verified that the resulting working state was on the newly published `master` commit and the `master` bookmark was pulled and active
Cascading diffs while on an earlier diff changeset
- I setup two diffs, each consisting of two commits, one depending on the other
- I put the working state onto a commit from the earlier diff
- I landed the later diff
- I verified that the resulting working state was on the newly published commit associated with the earlier diff, which is not the new `master` commit so there was no active bookmark
Cascading diffs while on the later diff changeset
- I setup two diffs, each consisting of two commits, one depending on the other
- I put the working state into a commit from the later diff
- I landed the later diff
- I verified that the resulting working state was on the newly published commit for the later diff which was `master` and `master` was active
Landing a non-tip revision, with evolve
- I setup three diffs, each consisting of two commits, creating a dependency chain
- I verified I had the evolve extension enabled via `hg debugextensions`
- I put the working state on a commit in the first revision
- I landed the second revision
- I verified that the resulting working state was clean, that revisions 1 and 2 were properly landed and published, and the resulting working state was on the published commit for the first revision.
Landing a non-tip revision, without evolve
- I setup three diffs, each consisting of two commits, creating a dependency chain
- I verified I did not have the evolve extension enabled via `hg debugextensions`
- I put the working state on a commit in the first revision
- I landed the second revision
- I verified that the resulting working state was clean, that revisions 1 and 2 were properly landed and published, and the resulting working state was on the published commit for the first revision.

- I setup three diffs, each consisting of two commits, creating a dependency chain
- I put the working state on the latest tip revision commit and its bookmark
- I landed the second revision
- I verified that revisions 1 and 2 were properly landed and published, and the resulting working state was still on the latest tip revision commit and its bookmark was active.

Summary:
When non-ascii characters appear in revision titles/summaries the `patch` and `diff` (to update) commands will fail on Windows systems. This often occurs due to “smart quotes” or "em—dash" characters being inserted into commit messages by editors on "user-friendly" operating systems like macOS.
This can be worked around by forcing all mercurial commands to use the global option `--encoding utf-8` which applies for any mercurial command. This option was [[ https://www.mercurial-scm.org/repo/hg/rev/a88e02081a88 | added in ~2006 ]] so this should work across all supported versions of mercurial.
Refs T13649
Test Plan:
I created a diff on a mercurial repository using smart quotes in the "Title" and "Summary" fields as well as in the content of a file being changed. Then on macOS, Windows (PowerShell), and Windows (cmd.exe) I was able to `patch` down the revision, make a modification, and `diff` the change back up to Phabricator, as well as `land` the change. I verified the commit and content looked correct on macOS as well as on Windows by using `nvim` which seems to properly detect and render the encoding, whereas mercurial displays the smart quotes and em-dashes with odd characters instead.
I did a grep through Arcanist codebase to find other places where `--encoding` might be specified for mercurial commands and could not find any. In the event that somehow this argument is added elsewhere I verified that multiple specifications of `--encoding utf-8` does not cause any issues and the later specification of `--encoding` appears to "win".
```lang=console
$ hg --encoding utf-8 --encoding utf-8 log -r tip
# prints out results in UTF-8 without issue
$ hg --encoding utf-8 log --encoding latin-1 -r tip

Ref T13562. Currently, "Filesystem::copyFile()" uses "copy", which doesn't work now that we no longer invoke "cmd.exe" by default.
Use "copy()" instead.
Note that this whole function is probably nonsense, but I'll follow up on T13562.
Test Plan:
- Created a standalone script which runs "Filesystem::copyFile()".
- Before: failed to copy any file.
- After: succesfully copied normal files.
- After: failed to copy a file over an existing directory with a reasonable error.
- After: failed to copy a file over itself with a reasonable error.

Summary: The ".git/arc" directory may need to be created when writing to working copy configuration.
Test Plan:
- Tried to store an answer to a prompt in a new working copy.
- Before: error that ".git/arc" does not exist.
- After: prompt saved to working copy configuration.

Summary:
Ref T13576. See that task for discussion.
When a user runs `arc land --pick A`, they may be selecting a range of commits ("X..Y") which have ancestors ("V..W") that should NOT land.
We must slice "X..Y" out of history before we can merge it, to avoid landing changes from "V..W".
When "X..Y" is simple and linear, we can rebase the range to pick our desired slice out of history.
When "X..Y" includes merge commits, we frequently can not, and I could not identify any simple alternative. The best alternative I came up with is this "reduce" operation:
- squash "into" onto Y, producing S, to guarantee there are no natural conflicts;
- squash S onto X^, producing T, to get rid of the merge commits;
- rebase T onto "into", producing R, to slice "X..Y" out of history;
- squash R onto "into", producing Q. (R and Q will be the same, but this simplies the code.)
This feels flimsy and fragile, but I can't immediately find a way to break it. See T13576 for more discussion.
Test Plan:
- Applied conflicting changes to `example.txt` in `master` and `feature1`.
- Ran `arc land`, got a merge conflict.
- Resolved the conflict with `git merge master`.
- Ran `arc land`.
- Before: merge conflict.
- After: `arc land` resolves the merge correctly.
- Stacked `feature2` on `feature1`, and made various mutations to `feature1` and `feature2`, then ran `arc land --pick feature2`. Changes made in `feature1` should not land, and they mostly do not. See T13576.

Summary:
Ref T13576. The "implicit commits" prompt in "arc land" shows a list of implicit and non-implicit commits.
The implicit commits are marked with a background color, but this doesn't survive if you copy/paste the output into a support ticket.
Make my life easier by also marking commits so the marker survives copy/paste.
Test Plan: Ran "arc land" with implicit commits, saw a copy-pastable indicator.

Summary:
Ref T13624. If we want to send PHP errors to a log, using the "error_log" configuration option catches the broadest set of errors across versions of PHP.
Configuring this disables errors on `stderr`, since they're sent to the log instead. We'd like them to go to both places; provide a simple wrapper for this. Also do a bit of writability testing.
Test Plan: Wrote errors to a new log, see followup changes.

Ref T13100. Ref T13586. These options have been in production for a while and seem to consistently improve behavior, downgrading segfaults to runtime errors.
Make them global options for all CLI environments. See next change for web enviornments.

Summary: Ref T13608. Ref T13100. Ref T13586. Properly checking "preg_match()" and similar calls for failure and raising useful exceptions is complicated and error-prone. Provide wrapper functions with an API that's more consistent with the rest of the codebase: matches are returned; and errors raise detailed exceptions.
Test Plan: See next change.

Summary:
These are the instructions from https://github.com/golang/lint.
The fetch location changed to `golang.org/x/lint/golint` from `github.com/golang/lint/golint`.
`-u` tells go to update the package and its deps if they exist.
`-u` Shouldn't strictly be necessary, but figured we might as well follow the instructions from `golint`.
Test Plan:
Enable golint without having it installed.
Ensure that the install instructions now show the new location.

Summary:
Ref T13588. For consistency of behavior between versions on either side of PHP7, any "catch (Exception)" block should generally have a "catch (Throwable)" block in the same catch list.
Raise a lint warning when "Exception" is caught without also catching "Throwable", since this is almost certainly not desired.
Test Plan: Added tests.

Summary:
Ref T13598. If you spell a symbol like "Polygon" as "PoLyGoN", you currently get an "unknown symbol" lint message. However, provided "Polygon" is a valid symbol, we can unambiguously correct the spelling of the symbol.
Note that this patch can only correct the spelling of application symbols, not builtin symbols (since none of the library maps contain builtin symbols).
