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:
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".

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.

Still, it seems consistently faster across multiple runs.

Ref T13130. I want to take a crack at improving performance here, but two possible approaches (inlining the actual encoding; using integers if they're big enough) aren't easy to test right now.
Restructure the tests so they can support these kinds of refactoring.
The "32bit" and "64bit" modes currently do the same thing, but I expect to introduce introduce separate encoding pathways in a future change, if the profiler says it actually helps.
(I'll hold this and everything that comes after it until I make meaningful performance improvements.)
Test Plan: Ran `arc unit`, got passes on tests.

Summary:
Filenames are last in `git status --porcelain=2` lines; they
are not escaped in any way, despite the fields being
whitespace-delimited. `explode` thus happily chops apart filenames
with spaces in them, causing later git operations to operate only on
the filename up to the first space.
Split the lines into the right number of elements -- in all cases,
this is one more than the index we're using, since filenames come last.
Test Plan:
Altering a file with a space in its path, and running `arc diff -a`.

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.

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.

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.

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.

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.
- Viewed some normal diffs to make sure intraline edits still displayed correctly.

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
Windows when storing the names of the files with lint messages. This causes no lint message's path to match the set of
changed files, and thus no lint warnings are ever produced.
If a lint message's file is not found using the provided filename, also try looking up the UNIX-style filename, on Windows when determining if a lint mesage is "relevant."

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").

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

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.

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

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.

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.
