Summary:
Make sure on failure (restoreBranch()) we call `git submodule update --init --recursive` to handle all those purdy submodules. For the pushing step, wrap the push commands in the try / catch block so everything gets cleaned up nice if there's failure. BONUS - add --recursive to arc patch workflow to so nested submodules work correctly. (Crazy git users)
Fixes T3407, T2945.
Test Plan: I wasn't sure how to simulate a good "push" failure but I think this should work.

Summary:
When running arc diff in a repository that supports commit ranges, it is
possible that the setting for the default relative commit hasn't been set.
If this is the case, the user will be prompted. This change makes sure that
the prompt happens (and thus the setting is set) before we run the
background lint and unit runs.

Summary:
We have some linters that trigger based on the path name
in the tree (some rules apply in some dirs and not others).
The changes in D6798 caused all the paths to appear to be outside
the tree, so allow for passing a fake through from those test cases
that are sensitive to this.
We also have a test for the copyright linter, and that needs to read
settings from the .arcconfig file. The change to faking a working
copy meant that this config option was effectively unset, so add a way
to pass the entire arcconfig through from the tests that need it.
Lastly, the logic to skip deleted files needs to be special cased
when we're faking paths like this: if we've added data for a file
in the testable engine, we should also consider that file as existing.
Test Plan:
`arc unit --everything` here, and passing our tests in
our repo over there.

Ref T3186. Ref T2039. Ref T3771. A few effects here:
# Expose PHPCS as a `.arclint` linter.
# Turn PHPCS into an ArcanistExternalLinter linter.
# Add test coverage for PHPCS.
# Add a `severity.rules` option to `.arclint`. Some linters have very explicit builtin severities ("error", "warning") but their meanings are different from how arc interprets these terms. For example, PHPCS raises "wrong indentation level" as an "error". You can already use the "severity" map to adjust individual rules, but if you want to adjust an entire linter it's currently difficult. This rule map makes it easy. There's substantial precedent for this in other linters, notably all the Python linters.
For `severity.rules`, for example, this will turn all PHPCS "errors" into warnings, and all of its warnings into advice:
"severity.rules" : {
"(^PHPCS\\.E\\.)" : "warning",
"(^PHPCS\\.W\\.)" : "advice"
}
The user can use `severity` (or more rules) to get additional granularity adjustments if they desire.

Ref T3776, Ref T479. Say you have some DN, with a submodule X@Y. Later, X@Z in your working copy / repo. If you run arc patch DN, you'd end up with a dirty working copy claiming that X@Z was wrong and it should be X@Y.
To fix, basically run 'submodule init' and 'submodule update'. This makes it so after "arc patch" if you run "git status" it looks clean.
Gross part though now is if you then "git checkout master" you'll have a dirty checkout the other way. I think this is better though.

Summary:
Currently, we prompt the user to mark non-UTF8 files as binary, but don't actually attach the data to the change when they do. This means we don't upload the data, and can't patch it later.
A simple reproduction case is to build a test file (I used one with bytes from 1..255):
$ # Don't include \0, since Git treats that specially.
$ ./echo_every_byte_from_1_to_255_inclusive.erl > example.txt
Then add it:
$ git add example.txt
$ git commit -a -m derp
$ arc diff --only HEAD^
You'll be prompted to convert the file to binary:
Do you want to mark this file as binary and continue? [Y/n] y
Before this patch, that would be followed by:
Uploading 0 files...
...which is incorrect; we need to upload the new data. After this patch, this shows:
Uploading 1 files...
...which is also incorrect, but only grammatically. Diffs created after this patch apply back cleanly with `arc patch` and restore the file properly.

Summary:
Ref T2039. That task has a bunch of discussion, but basically we do a poor job of serving the midrange of lint configuration right now.
If you have something simple, the default linters work.
If you have something complex, building your own engine lets you do whatever you want.
But many users want something in between, which isn't really well accommodated. The idea is to let you write a `.arclint` file, which looks something like this:
{
"linters" : {
"css" : {
"type" : "csslint",
"include" : "(\.css$)",
"exclude" : "(^externals/)",
"bin" : "/usr/local/bin/csslint"
},
"js" : {
"type" : "jshint",
"include" : "(\.js$)",
"exclude" : "(^externals/)",
"bin" : "support/bin/jshint",
"interpreter" : "/usr/local/bin/node"
}
}
}
...which will provide a bunch of common options around lint severity, interpreter and binary locaitons, included and excluded files, etc.
This implements some basics, and very rough support in the Filename linter.
Test Plan:
Generated a `.arclint` file and saw it apply filename lint correctly. Used `debug` mode and tried invalid regexps.
{
"debug" : true,
"linters" : {
"filename" : {
"type" : "filename",
"exclude" : ["@^externals/@"]
}
}
}
Next steps include:
- Provide an external linter archetype (T3186) and expose a common set of configuration here ("bin", "interpreter", "flags", "severity").
- Provide a `.arcunit` file which works similarly (it can probably be simpler).

[Preview] Creating Arc Revert workflow
Porting arc revert from FB4A to phabricator for general usage. This is my first stab,
so totally appreciate feedback and assistance. I'm currently focused
on making this work for git. However, I built out the functions through the GitAPI so this
could be easily extendable to Mercurial later on.
Stuck on the following (help):
1. Creating a task for FB internal. I tried building on top of existing arc listeners
but getting errors on failures to load the TaskCreator (and other) tasks.
2. I'm using a hacky way to grab the diff revision id from the newly created
revert diff. (see line 204) I'm looking for a way to just fetch the diff ID
from arc after the diff is created; is this possible?
Test Plan:
-
1. Ran arc revert on a www and fbcode diff
2. Confirmed that revert was run on the diffs and a proper diff filed

During my attept to `arc land master` on `master` branch
I have discovered that error message is missing few spaces between words.
I have added them and used this ugly readonly command:
pcregrep --include="\.php$" -M -r '(?<!\\n| )("|'"'"')\.\n\s*\1(?!\\n| )' ~/arc/arcanist/src
to detect other instances of this serious bug.
Two more were found.
This time they were probably introduced in order to abide
to the draconian lint rule about number of columns.
Since I want to be a good citizen,
I have added this missing space to the begining of the next line in both cases.
It is an ugly hack, but I think user should not suffer due to missing spaces.
Another solution could be preserving no leading spaces and splitting long lines.
Or just providing excuse to lint.

Summary:
Fixes T2266. Motivation:
- The lint cache does not always invalidate correctly. Because of the nature of the cache, this is a hard problem (right after "naming things").
- We already have a fair amount of complexity in trying to invalidate it, and are still discovering new places where it doesn't work (e.g., Windows with "/" vs "\" paths).
- One invalidation failure is when linter code changes, which seems unresolvable in the general case (e.g., changes to external linters).
- It's not obvious what's happening when the lint cache causes some kind of issue.
- Particularly while developing or debugging linters, your changes often won't be reflected in the lint output. Some of this is theoretically tractable but the external linter case probably isn't.
- When someone reports a problem with the lint cache in IRC or elsewhere, there is essentially never a way for me to fix it. The lint cache can't be debugged effectively without access to a working copy where the problem reproduces.
- The cache provides limited benefit outside of Facebook's install.
To remedy these issues:
- Introduce configuration which controls cache usage.
- Default it off.
- Print a message when the cache is in use.
(I'd tentatively support removing the cache entirely, but I don't know how @vrana and Facebook feel about that.)
Test Plan: Ran `arc set-config --show`, `arc lint --cache 0`, `arc lint --cache 1`.

a branch is called `spec` and there is a directory in `www` called

This adds a arcconfig setting to allow specifying whether to use the merge
or rebase strategy when doing the feature branch update.
arc.land.update.default can be set to either 'rebase' or 'merge'. The command
line flags will override this setting.
We have had trouble with arc land producing merge commits (introduced
with D4080) in git. They usually appear when arc land fails, and our users
are confused by the presence of a merge commit afterwards. Today it got even
worse since a user managed to get arc land to push the merge commit to the
server. This setting will allow us to turn it off for our uses.
Test Plan:
Verified the following combinations:
update.default not set + arc land (saw git merge in the trace)
update.default = 'rebase' + arc land (saw git rebase)
update.default = 'merge' + arc land (saw git merge)
update.default = 'rebase' + arc land --update-with-merge (saw git merge)

This makes the scenario for stacked diffs nicer. A user can commit A, commit B,
arc diff, commit C, commit D, arc diff, arc land B, arc land D.
Test Plan:
Commit A on top of master
Commit B on top of A

The `emailuser` template is a relatively recent addition to Mercurial, and a few users have complained about it. It also doesn't actually do what I thought it did, e.g. in an address like this:
"Abraham Lincoln" <alincoln@whitehouse.gov>
^^^^^^^^^^^^^^^ ^^^^^^^^
(1) (2)
^^^^^^^^^^^^^^^^^^^^^^^
(3)
...I want (1), but `emailuser` means (2). Instead, extract (1) with `getDisplayName()` and (3) with `getAddress()` using PhutilEmailAddress.
The implementation in Mercurial is not particularly sophisticated or magical (it just looks for "@" and "<") so we aren't really missing anything by doing this ourselves, at least today.
Also fix some issues in `arc export`, which literally no one uses, but which is occasionally useful for testing (as here).

This adds a hook to allow external parties to provide config settings at runtime.
The hook is technically for when a RepositoryAPI is created, but that moment can

Summary:
Previously, arc patch would create a new commit under the existing
current bookmark in mercurial. There have been two discussions about what the
right behavior should be (D3334 and D3658). One side wants no commit at all,
and one side wants a commit under a new bookmark. The current implementation is
the worst of both worlds :(
This change makes it create a new bookmark at the revision's base before commiting,
same as the --bookmark flag used to do (which is now obsolete). That way the
existing bookmark doesn't move (in mercurial >=1.8). This is the same behavior
git has, which is convienent for groups migrating between the two.
Also makes hg's getCanonicalRevision handle svn revisions just like git. This way
arc patch will try to apply the patch to the appropriate revision in the history.
Test Plan:
Ran:
arc patch - Verified it created a new bookmark and commited on top of the
revision's base commit.
arc patch --nobranch - Verified it put the new commit on top of the current
bookmark without a new bookmark.
arc patch --nocommit - Verified it left all the changes in the working copy.

Summary:
Adds error handling for several kinds of failure in arc land for
mercurial. Previously it would often leave the repo in a confusing state
if something failed.
- Aborts the land if pull brings in a diverged 'onto' branch.
- Aborts the rebase if there is a conflict. This leaves the repo exactly as
it was before, so the user is not left with a half finished rebase.
- Don't delete the original non-squashed branch until the push succeeds.
- If the push fails, strip the temporary squashed commit. This leaves the
'onto' branch back on the latest commit from the server, and leaves the users
original nonsquashed branch around.
- Always leave the user back on their original branch after an error.
Test Plan:
Ran arc land:
- with pull causing a diverged 'onto' bookmark
- with the 'onto' bookmark already diverged
- with the rebase causing conflicts
- with a push that failed due to a commit hook
- with a successful land
- with a successful collapse and land
In all failure cases the repo was left exactly as it was before arc land,
except for the push-failed case, where the only change was that the branch
was correctly on top of the destination branch due to a successful rebase.
Used bookmark name "foo bar-gah" to test that crazy bookmark names still work.

which didn't parse. Even if I fix that it still doesn't work because
getRawDiffText did not include the working copy changes (which it does
in git). I removed the check so the function now acts the same as in
git and arc lint works on working copy changes. I've seen this error before
in other places so hopefully this change will also fix any other areas,
that depended on getRawDiffText working the same as git.
The logic I removed was added in D1954 to support diffing against
uncommited changes. That workflow should be unchanged. arc diff will
still prompt the user if there are uncommited changes, and the user can
still choose to abort or continue.
Let me know if I missed something important which makes this a bad idea.
Test Plan:
Edited a file in the working directory of a hg repo.
arc lint
Verified lint ran successfully.
Also ran arc diff and land with and without working copy changes to make sure
they still work. I'd kill for some tests in this area...

Summary:
Add linting capability for detecting files which contain
syntax introduced by unresolved merge conflicts. The detection is
file-type-agnostic (the only requirement is that the file is a text
file).
Test Plan:
Tested in three ways.
The first way is to add all three forms of syntax to a file to
indicate a merge conflict. HPHP will pick this up as a syntax error
before this linter reaches it.
The second way is to add the syntax in a comment. In that case, this
linter will show three warnings. For example:
$ arc lint ArcanistMergeConflictLinter.php
>>> Lint for arcanist/src/lint/linter/ArcanistMergeConflictLinter.php:
Warning (MERGECONFLICT1) Unresolved merge conflict
This syntax indicates there is still an unresolved merge conflict.
20
21 foreach ($lines as $lineno => $line) {
22 /*
>>> 23 >>>>>>>
24
25 =======
Warning (MERGECONFLICT1) Unresolved merge conflict
This syntax indicates there is still an unresolved merge conflict.
22 /*
23 >>>>>>>
24
>>> 25 =======
26
27 <<<<<<<
Warning (MERGECONFLICT1) Unresolved merge conflict
This syntax indicates there is still an unresolved merge conflict.
24
25 =======
26
>>> 27 <<<<<<<

The last test was to test on various different file types, including
JavaScript, PHP, an animated GIF, a PNG, and a Bash file to make sure
the file type detection worked. Each of the aforementioned tests
passed.

Summary:
Mercurial 'arc land --hold' was taking 90+ seconds on our large
repository. Since most of arc land doesn't require any particular working
directory, I've changed the mercurial logic to avoid all updates except for
two: the one prior to finding the revision (only applies if the user specified
--branch), and the one at the end to leave the user in a good state.
Also got rid of a 'hg outgoing' call when phases are supported. Also changed
the hg-subversion detection to just look for .hg/svn instead of running 'hg
svn info', which was taking 4 seconds.
Now arc land takes about 50 seconds. Still much worse than git's 25 seconds.
One big hot spot is in the two 'hg rebase' calls, which account for 25 seconds
(versus 11 seconds of git).
Test Plan:
Tested arc land with mercurial and git. Tested with and without the --branch
options.

After D4383, we escape the base commit when constructing a command like this:

However, if the base commit is a revset like ".^", we now escape it and Mercurial looks for a commit named ".^" (a valid mercurial branch name) instead.
Fix this by returning nodes for these rules instead of revsets. The "arc:this" rule is automatically used in some operations, like "arc amend", so users can hit this during normal workflows, not just with weird `--base` rules.

Summary:
arc diff on large mercurial repos was taking 14 seconds just to get
to the commit message prompt. With these optimizations it takes 4.
- "ancestor(.) - ancestor(XYZ)" is expensive because it has to build the
entire 400000+ revision history for both. "XYZ::. - XYZ" is much cheaper
because it only looks at the revisions between XYZ and the working directory.
- "hg outgoing" has to talk to the server, which is slow. "hg log -r draft()"
gives us the same information and is much cheaper. We fall back to 'outgoing'
on older versions of mercurial.
Of the remaining 4 seconds, 2.5 are spent in 'hg status', which is a bit harder
improve.
