8c4f6ce161 Merge the remainder of the "experimental" branch
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.

Test Plan: Ran various `arc` workflows.

cc1ff38843 When generating diffs in "arc diff", disable Git config option "diff.suppressBlankEmpty"
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:

7383c2f4e6 In "arc land", when "remote/onto" does not exist locally, try to fetch it before giving up
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.

3cdfe1fff8 When running "arc land" from a detached HEAD, don't try to delete the source ref
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.

7329bc7c32 Fix arc land on odd/modern git-svn checkouts
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).

dd514e268b Modify the lint-test file format to allow for more powerful assertions
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.

73804f0039 Fix a case where "arc patch" could skip submodule changes
Summary:
See PHI1083. Previously, see PHI648 and D19475.

When you apply a submodule patch in Git, it leaves you with a working copy that has the "submodule pointer" dirtied but the actual submodule untouched:

```
$ git status
On branch ...
Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)

	modified:   philter

Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

	modified:   philter (new commits)
```

So, if you're applying `D123` and `submodule/` was previously pointed at commit "A" but `D123` updates it to point at commit "B", you get this after `git apply ...`:

  - Git index says "submodule/ = B".
  - On disk, "submodule/ = A".

Now, if you `git add --all` or `git commit --all`, git picks up the "change" on disk as an intended modification of the submodule. This puts the submodule back to "A" and overwrites/undoes the "pointer" update that's trying to make it point to "B".

To avoid this, update submodules after applying the patch.

Also, every time we modify the working copy, just update submodules.

Test Plan:
  - Add a submodule in branch "B1", pointed at commit "A".
  - Branch to create branch "B2". Update the submodule to point at commit "B". Commit this and `arc diff` it.
  - Go back to "B1". Use `arc patch D...` to apply the revision you just created.
  - Before change:
    - "arc patch" applies the submodule change, so "pointer = B", "disk = A".
    - "arc patch" runs "git commit --all", which looks at disk and sets "pointer = A".
    - This isn't a change, so we fail with an empty commit.
  - After change:
    - "arc patch" applies the submodule change, so "pointer = B", "disk = A".
    - "arc patch" updates submodules, so "pointer = B", "disk = B".
    - "arc patch" runs "git commit --all", which now has a change, and commits "submodule = B".

96fde137a1 Improve performance of "arc diff" updates for changes with large diff text
Summary:
See PHI1104. The older "differential.querydiffs" method includes the entire raw diff text for all the diffs associated with a revision in its response, but we: only care about the most recent diff; and don't care about the text at all.

For reasonably large changes with several updates, this can be significantly slow.

We can get this same information more efficiently from the modern "differential.diff.search", since D19386 (April 2018). The only trick is that we need a "revisionPHID", which we don't have on hand.

For now, just fetch the revision PHID. In the future, we can likely make adjustments so that we have the revision PHID already by the time we get here.

This may slow down the normal case very slightly (since we now do two calls instead of one), but it speeds up the bad cases dramatically.

Test Plan:
Ran `arc diff` to update a change in a local repository. `var_dump()`'d the old and new algorithm results, saw the same outcome.

Used `arc diff --trace` on an update to a change to verify that `differential.diff.search` is called but `differential.querydiffs` is not.

9581dd0f52 Add Arcanist support for highlighting indent change intraline diffs
Summary:
Ref T13161. See D20181. This allows the intraline highlighter to accept new ">" and "<" spans and apply a different style for them.

The input pattern is `list<segment>`. Each segment is `pair<wild kind, int byte_length>`, i.e. wrap the next `byte_length` bytes in a span of kind `kind`.

Before this change, the possible kinds of segements are `0` (no intraline diff, do not highlight) or `1` (intraline diff, highlight in bright color).

D20181 adds `<` (depth decreased) and `>` (depth increased). These are like `1`, but add a different class so the UI can handle them differently.

Ref T13249. See PHI810. We currently warn you when //all// reviewers are away, but not when only some reviewers are away.

This makes some amount of sense under the "anyone can accept anything" rules we sort of recommend, but a lot of installs realistically have tons of owner/package rules now.

Instead, if any reviewers are away, show the user exactly who is away and until when, then make sure they don't want to make any adjustments.

(We can do a better job of this after the toolsets change when we can use the new APIs, but this is an easy fix for now.)

83661809e5 Work around a Windows escaping issue and security conecern in "hg cat --output ..."
Summary:
See PHI904. Ref T13210. Ref T13209. Currently, we have an `hg cat` construction which attempts to pass a literal `%p` to Mercurial. This fails because you can't pass `%` through `%s` outside of `wilds`.

It also uses `%C` to pass a list of file paths. This is broadly unsafe and can cause command execution if you modify a file named, e.g., `; rm -rf xyz` or similar. I think it would be difficult to turn this into an attack but it's fairly bad. This dates from D5144 in 2013.

Test Plan: With this patch, created D19757 which has valid binary data (see F5962134).

2650e8627a Make the Arcanist comment remover less aggressive about stripping instructional comments

```

...we'll currently eat the `#projectname` as an instructional comment, even if it is followed by an empty line.

Instead, stop eating stuff once we hit the first empty line. (We escape empty lines in comments already.)

After T13098 I'll maybe adjust this to use a more explicit instruction escape, like `##`, since there's no reason we're bound to `#`.

30b7835c37 Allow willLintPaths and didLintPaths to be overridden
Summary: I'm not sure if the upstream will be interested in this change, but we are writing a linter which works by running an external command on the entire repository. This can't be done with `ArcanistExternalLinter` at the moment, which meant that we ended up copy-pasting most of `ArcanistFutureLinter`. This would be a lot easier if we could override `willLintPaths` and `didLintPaths`, but these methods are currently marked as `final`. An alternative solution would be some sort of `ArcanistLinter::transformPath` method.

e1e93271e6 Make the ArcanistBundle algorithm do what "diff -u" does when hunks are arguably mergeable
Summary:
Ref T13187. See PHI838. If two hunks are separated by 7 lines of context, we can render them as either:

```lang=diff
+ Hunk A
  Context 1
  Context 2
  Context 3
  Context 4
  Context 5
  Context 6
  Context 7
+ Hunk B
```

...or:

```lang=diff
+ Hunk A
  Context 1
  Context 2
  Context 3
@@ +1,2 -3,4 @@
  Context 5
  Context 6
  Context 7
+ Hunk B
```

Since we get the same number of output lines either way and the first one is more human-readable, we picked that one.

However, `diff -u` does the second one. Since human-readability is probably less important than compatibility, change the behavior to be more similar to `diff -u`.

Test Plan: Added unit tests for the edge cases with default parameters (6 context lines, 7 context lines) and made them pass.

875d018360 Fix arc diff when adding large new file with new git
Summary:
See https://discourse.phabricator-community.org/t/arc-not-supporting-git-2-17-1/.
When treating it a large file  binary, we try to get the "old" and "new" content using `git ls-tree` and `cat-file`.
If the file is new or deleted, there is no old file, so we try to work with filename `null`.

Under git < 2.17.1, that gets treated as `git ls-tree -- .`, which falls in the next condition under "no such path".
In git 2.18, etc, this is an error.

Explicitly bail out if there is no filename.

d581c453b8 Allow diff generation via ArcanistBundle to be limited to an approximate maximum byte size
Summary:
Ref T13137. See PHI592. When you have a diff with 600MB of videos, we want to bail out of diff generation early (as soon as we realize what we're dealing with), not build an 800MB text diff in memory and then throw it away.

Support bailout //during// diff generation once we realize we're in over our heads.

This is approximate, but since the limit is fairly large (512KB by default) it isn't too important to be precise.

Test Plan: Rigged some callers to set various byte limits, generated diffs including diffs with large binaries. Got an appropriate diff or exeception depending on how low the limit was.

a604548101 Slightly improve base85 performance for 64-bit systems
Summary:
Ref T13130. I wasn't able make this much better, but it looks like this is about ~20% faster on my system.

This kind of thing is somewhat difficult to micro-optimize because XHProf tends to over-estimate the cost of function calls. In XHProf, this looks much much faster than the old version (~100% faster) but the actual cost of `bin/conduit call --method differential.getrawdiff` hasn't improved that much. Still, it seems consistently faster across multiple runs.

Test Plan:
  - Pulled binary diffs over Conduit with `bin/conduit call --method differential.getrawdiff`.
  - Verified that they are byte-for-byte identical with the pre-change diffs, and look like they're ~20% faster.
  - Profiled the differences and saw a far more dramatic improvement, but I believe XHProf is exaggerating the effect of this change because it tends to overestimate function call cost.
  - Ran unit tests (from D19407), got byte-for-byte identical output under both 32bit and 64bit mode.

Filenames are last in `git status --porcelain=2` lines; they

the filename up to the first space.

this is one more than the index we're using, since filenames come last.

349109426c Clarify what "--everything" means in "arc lint" and "arc unit"
Summary:
Fixes T13061. Both `arc lint` and `arc unit` accept an `--everything` flag, but the documentation isn't quite clear about what these flags do.

They act as though every //tracked// file in the repository (`git ls-files`, `hg manifest`, or `svn list -R`) is included in the argument list.

They do not lint/test ignored files (and I think almost all users would be very surprised if they did).

They also don't lint/test untracked files (files you have not yet used `git add`, `svn add`, or `hg add` on). This is slightly more contentious but we have good reasons for doing it (e.g., `git ls-files` often outperforms `find .` by a large margin) and I believe users very rarely use `--everything` in a situation where they have untracked files. The only real exception I can come up with is linter configuration/development, as in PHI343, and it seems okay to have a slightly surprising behvaior here.

Make the documentation more clear about what is in scope.

We could also rename these to `--nearly-everything` or whatever, but I think the name is probably clear enough given current information about how confusing this is (specifically: only rarely, in unusual cases).

Test Plan:
  - Grepped for documentation about these flags.
  - Ran `arc help lint`, `arc help unit`, `arc unit --everything x`, `arc lint --everything x` and read all the new messages.

2e02332216 Add trailing tabs when generating synthetic Git diffs for files with spaces
Summary:
Fixes T8768. See PHI294. See that task for more details.

Git, Mercurial, `diff`, and `patch` have conspired to make things weird. To correctly handle files with spaces in the way everything else does and expects, we need to emit semantic trailing whitespace literals.

Test Plan:
- Created a file with spaces in it in a Mercurial repositroy, committed it, diffed it into a revision.
- Used `arc patch` to apply the change to a clean copy of the repository.
- Before patch: Mercurial incorrectly creates a file named `X`, not a file named `X Y.txt`.
- After patch: `arc patch` commit is identical to genuine commit.
- Also added test coverage. The other general behaviors here are fairly well covered already.

9144658e69 Accelerate working tree operations in git
Summary:
Currently, `arc` on `git` uses the following commands to examine the
state of the working tree and history; example times for a no-op diff in a
165k-file working tree are also shown:

```
1)  git diff --no-ext-diff --no-textconv --submodule=short --raw 'fb062d4ecce5d9c1786b7bfc8a0dedf6b11fdd96' --
  = 1,722,514 us

2a) git diff --no-ext-diff --no-textconv --submodule=short --raw 'HEAD' --
  = 1,715,507 us

2b) git ls-files --others --exclude-standard
  = 2,359,202 us

3)  git diff-files --name-only
  = 1,333,274 us
```

Steps (2a) and (2b) are run concurrently; this results in a total elapsed
wallclock time of approximately 5.4 seconds.  This is inefficient -- all four of
the above steps must both load the index and examine the working copy, which may
be slow operations when large repositories are used.  Additionally, none of the
effort of those stat calls on the working tree, or load time of the index, is
shared across the processes.

Step (1) is called from `getCommitRangeStatus`, which was split out in D4095; it
is currently never called on its own, only ever from `getWorkingCopyStatus`,
where it it combined with `getUncommittedStatus`.  The current behavior of the
method is to return the set of changes //either// in local commits //or//
uncommitted in the working tree, which duplicates work that
`getUncommittedStatus` is intended to do.  Changing the behavior of this method
(in Git, and other VCSes) to only examine _committed_ status seems both inline
with the name of the method and the original description of it in D4095 -- and
also serves to make it much faster, as it is an operation that need not inspect
the working tree at all.

Steps (2a), (2b), and (3) attempt to gather the state of the working copy, and
as such are all I/O bound but must examine nearly identical data.  For git
2.11.0 and higher, we can instead rely on the machine-parseable `git status
--porcelain=2` format, which provides the information from all of these commands
at once.  It also allows additional performance improvements, as `git status`
has been the focus of several optimizations in the latest versions of git (the
untracked cache and fsmonitor services, for instance), which are not available
in the lower-level `diff`, `ls-files`, and `diff-files` commands.

This has the added benefit of fixing a bug noticed in T9455, in that uncommitted
or unstaged changes in modules can now be detected, regardless of if they also
have changed their base commit.  It further resolves a bug where `.gitmodules`
appeared to have unstaged changes, when in reality the unstaged changes were in
submodules elsewhere in the tree.

For backwards compatibility with versions of git < 2.11.0, the old code is left
in place.  It is possible that the simpler output from v1 of `git status
--porcelain` would also suffice for some of the above benefits, but the payoff
of parsing yet another format is deemed insufficient; users wishing improved
performance should simply upgrade `git`.

Alltogether, these result in the following, for a no-op diff in a
165k-working-file tree:

```
1) git diff --no-ext-diff --no-textconv --submodule=short --raw 'fb062d4ecce5d9c1786b7bfc8a0dedf6b11fdd96' HEAD --
 = 9,227 us
2) git status --porcelain=2 -z
 = 739,964 us
```

...for a total of 749ms, an improvement of 4.7s.

Depends on D18841.

This omits two features, which I'll port forward separately:

be67df6118 Extract and cover the logic for "trimming" a lint message
Summary:
Ref T9846. Sometimes, a lint message says to replace "the big bad wolf" with "the huge bad wolf": that is, the original and replacement text are the same at the beginning, or the end, or both.

To make this easier for humans to understand, we want to just show that "big" is being replaced with "huge", not that the entire phrase is being replaced.

This logic currently happens inline in console rendering. Pull it out and cover it so a future change can simplify console rendering.

c04f141ab0 Remove obsolete "arc land" flags: --update-with-merge/rebase, --delete-remote
Summary:
Fixes T12815. During the last update to "arc land", some flags were disabled but remained in place in case we needed to retain them.

It now seems reasonably clear that we do not. The "rebase" and "merge" strategies for landing were replaced by a better "headless" strategy which seems to avoid the original issues, so these flags no longer do anything or reasonably could do anything.

`--delete-remote` is slightly more ambiguous (e.g., see T12650 and maybe others) but the only real use case is "git push = save changes".

If the commit does not exist locally, aborting still leaves
the user checked out on the branch.  In nearly all cases, all that is
necessary is a fetch -- but the branch must also be cleaned up.  This

[...base commit does not exist...]

git checkout master
git branch -D arcpatch-D12345

d1db9a72b5 Improve the flake8 line-matching regex
Summary:
Because the character offset group is optional, the logic for dealing
with the previous index-based match object was more complex than it
needs to be. Switching to named groups makes this clearer.

As an example of how this was causing a problem, when the character
group *was* present (at index 3), it was being appending to the linter's
name in the call to ->setName(), resulting in confusing linter output.
We may have also been setting the character offset to the error code's
string, too, which is further nonsense.

Because we reliably capture the flake8 error code, I don't think there's
a need to append it to the linter's name at all now, so I removed that
part (so it's always just `flake8`), but it's not a problem to restore.

Lastly, I hoisted `$regex` out of the loop because it's a constant and
de-indenting it gave me enough room to continuing writing it all on one
line.

Test Plan: Tested primarily with flake8 3.3.0

c243cbbd9f tighten remote URI error handling with idiosyncratic remote names
Summary:
`git ls-remote` has an unusual way to indicate a URL was not
found: echoing back user input
```
$ git ls-remote --get-url does_not_exist

`getRemoteURI` handles checking for remotes other than 'origin', but
the error handling always matched against the string 'origin'
regardless of remote name.

Test Plan:
With a git config along the lines of:
```
[remote "my_special_name"]
        url = ssh://secure@secure.phabricator.com/diffusion/ARC/arcanist.git
        fetch = +refs/heads/*:refs/remotes/my_special_name/*

[remote "github"]
         # url = git@github.com:phacility/arcanist.git
         fetch = +refs/heads/*:refs/remotes/github/*
```

and running in a branch tracking `master` (github).  `arc which` would
(without this diff) show:
```
The remote URI for this working copy is "github".
```
With this diff, `arc which` correctly shows:
```
Unable to determine the remote URI for this repository.
```

When diffing against a tracking branch with a propertly configured
remote (the happy path), `arc which` still correctly identifies the
remote URI:
```
The remote URI for this working copy is
"ssh://secure@secure.phabricator.com/diffusion/ARC/arcanist.git".

2ad15c499a Don't compute intraline diffs if the input fails a coarse check for being huge
Summary:
Fixes T11744. Because intraline diffs are expensive to generate, we already bail out and decline to generate them for very long lines.

However, we currently split the inputs into lists of characters first, then check how long they are and make a decision to bail. For //huge// inputs (e.g., 1MB+), this is too late: just splitting them has a large CPU/RAM cost.

(These inputs are rare in normal source, but can appear in, e.g., JSON files written without newlines.)

Instead, add an extra "are the inputs really huge?" check first, and bail early if they are.

Test Plan:
  - Generated a 1MB "change a file full of Q to a file full of R" diff.
  - Before change: purged changeset cache; took about 7 seconds to load.
  - After change: purged changeset cache; took about 1 second to load.

Summary:
Paths are passed into linters using UNIX-style slashes (/), as returned from the version control system; however,
`Filesystem::readablePath` swaps them to Windows-style (\) on

changed files, and thus no lint warnings are ever produced.

9e82ef979e Added a warning prompt if the user tries to use an API cert instead of a CLI cert
Summary: Fixes T9692. Instead of disallowing API tokens entirely, we're going to just warn the user that they might not want to do that. After that, they can proceed if they want to.

Test Plan:
Run arc install-certificate.
Manually go to `Settings → Conduit API Tokens` in the web UI.
Generate an API token explicitly, which should have the form api-******.
Paste that into the prompt on the CLI.
It will give you a warning prompt then ask if you'd like to proceed anyway (defaults to No).

6507be27ae Fix handling of View Policy in CLI upload workflow for small, unique files
Summary:
Ref T7148. When uploading files from the CLI with a particular view policy, we may not respect it if the file is unique (so the data isn't already known) and small (so it doesn't invoke the chunker).

This is rare (and may never have happened outside of testing) because:

  - production dumps are always larger than the minimum chunk size;
  - only cluster stuff uses `setViewPolicy()`;
  - the default policy is "Administrators" anyway, which is safe.

However, I caught it in local testing, so fix it up.

Test Plan: Used `bin/host upload --file ...` to upload a small, unique file. Verified it uploaded with the correct custom view policy ("No One") rather than the default view policy ("Administrators").

d0957c3441 Parse git renames with inconsistent quoting or custom prefixes
Summary:
The previous parser failed when only one of the old/new filenames was
quoted, as with a rename of a Unicode filename to a non-Unicode
filename, or vice versa.  It also incorrectly parsed custom prefixes,
even going to far as to encode this logic in the tests: a diff of
"src/file dst/file" which is not a rename should not be recorded as
changing "src/file", but rather "file".

Switch to using the "rename from" / "rename to" as the source of truth
for old and current filenames when complex renames are done.  This
matches the logic that git itself uses to parse patches; the contents
of the `diff --git` line are merely viewed as a simplest-case
prediction, with renames handled later should it not match.

The diff parser already had logic to parse "rename from" / "rename to"
lines and extract their information.  As such, this diff consists
primarily of removing logic from the `splitGitDiffPaths` method, and
allowing it to quietly fail.

This resolves two ambiguity mentioned in comments and tests: in
renaming "old file old" to "file", as well as the renaming of
"old file with spaces" to "new file with spaces" when neither are
quoted.

Test Plan:
`arc unit`.  Many of the existing test cases no longer
applied to the `splitGitDiffPaths` method; they were moved into a new
test method which also supplies values for "rename from" and "rename
to" lines.

As noted in the summary, this alters one of the expected values of an
existing test.  Specifically, the following diff is a file addition of
`file` with custom prefixes, and not the addition of "dst/file":

```
diff --git src/file dst/file
new file mode 100644
index 0000000..1269488
--- /dev/null
+++ dst/file
@@ -0,0 +1 @@

ee6357386d Correctly parse file renames and copies from git diff --raw
Summary:
`parseGitRawDiff` dealt with the `A`, `M`, and `D` status flags from
`git diff --raw`, for file additions, modifications, and deletions
respectively.  However, it failed to cope with `C` and `R` flags, for
copies and renames.  Git version 2.9 and above default to resolving
renames, even in `git diff --raw` output, making this lack of support
only salient now (though users with Git's `diff.rename` set
encountered it previously).

Those two flags differ from the other three in that they offer both the
source and destination filename, separated by a tab.  As
`parseGitRawDiff` was not aware of this property, it returned a
"filename" of `"oldfile\tnewfile"`.  This is surfaced in several
places, including as passed to linters as a filename to check.
Needless to say, this file is nearly guaranteed to never exist on
disk.

Detect both the `C` and `R` flag types, and generate either a file
addition, or a pair of addition/deletion entries.

Test Plan:
Renamed a file, with a linter that printed each file it was
called with.

768e1a56bc When running XHPAST unit tests, include the "syntax error" lint rule
Summary:
See rARC3ffed59bd7. Currently, when a unit test includes a syntax error, it is raised in an unclear way ("error at line 10, char 1: XHP1 Unknown lint message!").

This is because each test case only activates rules it wants to test, so we lose the ID/name for the syntax message. However, we always want to test this and the lint engine can always raise it.

To get a better error message, include it unconditionally. So a test for rule `X` really tests two rules: syntax, and `X`.

Test Plan:
Ran `arc unit` at HEAD, got a better test failure:

```
   FAIL  ArcanistCallTimePassByReferenceXHPASTLinterRuleTestCase::testLinter
In 'call-time-pass-by-reference.lint-test', expected lint to raise error on line 10 at char 8, but no error was raised. Actually raised:
  error at line 10, char 1: XHP1 PHP Syntax Error!
```

NOTE: This doesn't pass tests yet, it just makes the test failure easier to understand. I'll see about fixing the test in the next change.

a2ab38df78 Improve performance of arc branch in Git with many branches
Summary:
This is mostly just a personal quality-of-life fix. I run this command fairly often and having it return a little faster is nice.

This replaces a `git show` for each individual branch with a big `git for-each-ref` which we were already running anyway. This is quite a bit faster.

This command also occasionally hangs or segfaults for me while executing the huge pile of subprocesses. This is unreliable to reproduce, probably some bug in some PHP extension I have, and likely hard to narrow down, and this approach is better in every way anyway.

Test Plan:
  - Ran `arc branch` in Git, observed faster output (in my `phabricator/`, about 2000ms -> 1200ms).
  - Ran `arc feature` in Mercurial.

737f5c0df9 Allow amending revisions without commandeering first
Summary:
It is common practice in Wikimedia's projects to amend a contributor's
change without taking over authorship of the change. We found that
the only enforcement of commandeering before amending is in arcanist,
not validated server-side. While it would be fairly straightforward to
maintain this as a patch to arcanist, I thought I would see if upstream
is willing to support making this optional.

With this change, amending without commandeering is enabled by a flag in
`.arcconfig` and it defaults to the old behavior.

For background see [wmf T121751](https://phabricator.wikimedia.org/T121751)

Test Plan:
* ran `arc patch D146` to locally apply a revision that I did not author,
* made a trivial change and amended the commit.
* ran `arc diff --update D146 HEAD^` to send the update to differential
* Saw that https://phabricator.wikimedia.org/D146 updated as it should.

4a1160e0c3 When pushing changes to staging, also push the base commit
Summary:
Fixes T10509. Pushing changes to staging can be inefficient. What happens, roughly, is:

  - Master is at commit "W" -- "W" is the most recent published commit in the main repository.
  - The local working copy has one change on top of that, "X", so its history is commits "A, B, C, D, E, F, ..., U, V, W, X".
  - The remote has some other previous changes that I or other users have made, maybe like "A, B, C, ..., S, T, U, Y" and "A, B, C, ..., T, U, V, Z", from previous pushes to staging areas.
  - "X", "Y" and "Z" will never actually make it to master, because they'll be squash-merged/amended by `arc land`.

So the local says "I want to push 'X'", and the remote says "I know about 'Y' and 'Z', are those in the history of 'W'? You only need to send me new stuff if they are".

But they aren't, so the local says "nope, so here's the whole history for you". This is slow and sends a ton of data that the remote already has over the network.

In theory, Git could use a slightly different algorithm to tell the local about more commits, but this is hard, rarely useful, and not the kind of thing I'd be excited about changing if I was the Git upstream.

Instead, when pushing "X", also push "W", to trick Git into telling future clients about it.

Now, the remote should say "I know about 'W', 'Y' and 'Z'", and the local will say "oh, great, 'W' is in history, here's just the changes since then".

Also, fail `arc diff` if the push to staging fails, and tell users to use `--skip-staging`. This code has been in production for a while and doesn't seem to have any issues, and a failed push to staging prevents builds, lands, etc.

Test Plan:
  - Ran `arc diff`, saw two changes push.
  - Ran `arc diff --base arc:empty`, saw only one change push.
  - Ran `arc diff` with an intentionally broken staging area, saw an error.

086f5399bf Filter out some Clover coverage to prevent false positives
Summary: Clover reports generated from PHPUnit sometimes give false positives of lines that were not covered by a test that should have actually been not coverable, apparently due to inaccurate static analysis of files that weren't actually executed. This filters coverage reports of files that show no coverage which avoids these false positives. Fixes T10420.

d6b1531b94 Use passthru to run git fetch in arc land so password prompts work
Summary:
Fixes T10314. In `arc land`, we currently run `git fetch` as a subprocess.

However, this can prevent password prompts (when fetching over HTTP with basic authentication) from working properly.

Instead, use passthru to redirect stdin/stdout to the subprocess so the user can type their password.

This adds a little extra clutter to the `arc land` output but I think that's OK.

Test Plan: See T10314, @maxie confirmed this fixes the issue.

22af67c1c0 Minor fixes to arcanist cpplint
Summary:
This fixes the regex in "getLintCode..." so that it accepts lint
codes such as `build/c++11` which have become valid lint codes
in later versions of cpplint.

It also corrects the install instructions for the linter (Google's
style guide is no longer available on SVN and has been migrated to
Github).

Test Plan:
For the Regex:
- Create an .arclint in a project such as:
```
{
  "linters": {
    "cpplint": {
      "type": "cpplint",
      "severity": {
        "build/c++11": "advice"
      }
    }
  }
}
```
- Run `arc lint` with the existing linter. This should fail. Patch the linter, and this should now be accepted.

For the Instructions
- Verify the download location `wget https://raw.github.com/google/styleguide/gh-pages/cpplint/cpplint.py`

dae2f0073f In arc diff, try to guess where a change should land
Summary:
Ref T9952. Ref T3462. My primary goal is to improve prefilling of the "Onto Branch:" field in the "Land Revision" dialog.

When uploading a diff with `arc diff`, add a property with some information about which branch to target. In particular:

  - If the local branch tracks an upstream branch (or tracks something which tracks something which tracks the upstream), target that.
  - If not, but "arc.land.onto.default" is set, target that.

This doesn't try to guess in other cases, since they're more involved. I'll add some context about this in T3462.

I don't //love// using "diff properties" for this, but it doesn't make cleaning them up any harder since we already use it for other stuff which isn't going away (lint/unit excuses).

Test Plan:
  - Added some `var_dump()` and used `arc diff --only` to generate diffs.
  - Saw upstream tracking and config-based rules generate reasonable values and submit them.

4f1141d0c5 Improve error handling in arc install-certificate
Summary: Fixes T9858. Reasonable typos and misunderstandings currently produce very confusing error messages.

Test Plan:
```
$ arc install certificate
Usage Exception: Server URI "certificate" must include a protocol and domain. It should be in the form "https://phabricator.example.com/".
```

  - Also used a good URI.
  - Also used no URI.

28f5b0ddc6 Fix a compatibility issue with ArcanistUnsafeDynamicStringXHPASTLinterRule
Summary: A user reported to me that `arc lint` was failing with an error message along the lines of "argument 1 passed to `idx` must be of type array, bool given". I suspect that the user is running an older version of PHP, which means that `array_combine(array(), array())` is returning `false` instead of the expected `array()`. Instead, avoid calling `array_combine` on an empty array.

Test Plan: I don't have PHP 5.3 easily accessible to test this.

ae210fda9f Add a linter rule for use statement namespace prefixes
Summary:
When importing or aliases a symbol with a `use` statement, the leading namespace separator is optional and does not modify the behavior. That is, `use \X` is equivalent to `use X`. As such, the latter syntax should be preferred because it is more concise.

According to the [[http://php.net/manual/en/language.namespaces.importing.php | PHP documentation]]:

> Note that for namespaced names (fully qualified namespace names containing namespace separator, such as `Foo\Bar` as opposed to global names that do not, such as `FooBar`), the leading backslash is unnecessary and not recommended, as import names must be fully qualified, and are not processed relative to the current namespace.

Test Plan: Added test cases.

b32149495b Don't give Mercurial empty string as a remote name
Summary:
Fixes T9807. We currently run commands like this in some cases:

  hg push -r master ''

From T9807, it seems that older Mercurial treated `''` in the same way it would treat no argument, while newer Mercurial does not.

Passing `''` is unusual and not intended.

Test Plan:
From T9807, @cspeckmim confirmed that running this command without the `''` works, and @jgelgens tested the patch itself.

I didn't actually run this code myself, since I don't have Mercurial 3.6.1 installed and the fix seems straightfoward.

  public function __construct() {
    return 'quack';
  }
}
```

This doesn't work:

```lang=php, counterexample
echo new SomeClas();
```

This, strangely, does work:

```lang=php
echo id(new SomeClass())->__construct();
```

4d512c51d4 Test XHPAST linter rules in isolation
Summary:
Separate XHPAST linter rules in isolation from other rules and formalize the concept of a "linter rule". As the number of XHPAST linter rules grows (we currently have around 80), it becomes increasingly difficult to manage all of the test cases because `ArcanistXHPASTLinterTestCase` currently tests the entire linter (i.e. //all// linter rules) rather than testing individual rules in isolation. See D13534 for a situation in which this is painful. This is particularly bad for third party development because unit tests could break at any time depending on upstream changes.

Basically, in order to facilitate the unit testing of XHPAST linter rules in isolation, I have made the following  changes:

  # Added a `setRules()` method to `ArcanistXHPASTLinter`. Currently, `ArcanistXHPASTLinter` loads all `ArcanistXHPASTLinterRule` subclasses unconditionally. The `setRules()` method provides a way to override the configured linter rules.
  # Formalize the concept of a "linter rule". The `ArcanistXHPASTLinterRule` class was introduced in D10541. I feel that the modularization of `ArcanistXHPASTLinter` has made the linter much more maintainable and easily testable and I intend to extend this concept to other linters, such as `ArcanistTextLinter`.

Test Plan: Ran unit tests.
