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.

Test Plan: Add a new, large (>4Mb) file, arc diff.

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.

bcab677a7a Restructure base85 unit tests to support inlining and multiple encoding pathways
Summary:
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.)

ad3087e5e1 Correctly parse git status --porcelain=2 output with filenames with spaces
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`.

Added tests.

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.

Test Plan: Existing tests.

86779b1526 Render lint patches which have newlines in a less misleading way
Summary:
Ref T9846. This rewrites the rendering algorithm in a mostly-compatible way and fixes the major issue.

  - Includes test coverage for removing a newline, from T12765.
  - Includes test coverage for mangling an XML tag, from T9846.

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

  - For one-line patches, highlighting the patched section.
  - For zero-line patches, putting a little caret ("^") under the character where the warning occurred.

I'll restore these features in a followup change.

Test Plan: Ran unit tests, linted a few things.

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.

Summary:
`PhutilConsole->confirm()` is vestigial as noted in efcd70c, as
`PhutilConsole` may be deprecated sometime in the future. `PhutilConsole`

`phutil_console_confirm()`. There should be no change in functionality
since the two functions are interchangeable.

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".

Test Plan:
Ran `arc land --update-with-rebase`, was told the flag does not exist.

129d51fa09 If the base commit for arc patch does not exist locally, try to fetch it
Summary:
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

```
arc patch D12345
[...base commit does not exist...]
^C
git checkout master
git branch -D arcpatch-D12345
git fetch

Note that it's fine if `arc` and Phabricator disagree about hashing algorithms. We don't really trust the client anyway, so if things are mismatched clients will just end up transferring a bit more data instead of getting to cheat when Phabricator already has copies of data.

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.

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

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.
