2fa80bbd44 Add canRun to linters.
Summary:
This allows engines to check the canRun method on linters,
which should determine if a linter is configured and can
be run in the current environment.

Test Plan:
Implement a linter with canRun as false, and ensure
it doesnt run.

Ensure all existing linters still run by default.

06334a69b4 Improve PEP8 Linter
Summary:
This cleans up the PEP8 linter to bring it inline
with the new JSHint Linter's level of quality.

It adds a getPEP8Path method which gives the ability
for users to override the pep8 binary with two new
options in .arcconfig:

* lint.pep8.prefix
* lint.pep8.bin
* lint.pep8.options

Test Plan:
Adjust your engine to use the 'ArcanistPEP8Linter' and run
arc lint against Python files.

5cd2eec6f1 Implement Comprehensive Lint Engine
Summary:
This adds a new lint engine, ComprehensiveLintEngine, which
includes sane defaults for some generic languages.

Ideally this would include *all* available language linters,
but that can be enhanced at a later point. Right now it's mostly
the base linter with additional JavaScript and Python linters.

Test Plan:
Adjust the lint_engine to be "ComprehensiveLinterEngine". You'll
also need jshint, pyflakes, and pep8 to all be available on PATH.

Run arc lint against files which contain .php, .py, and .js.

6c613292f7 Make arc patch be less ROFL for mercurial
Summary:
pretty easy stuff as mercurial accepts git style patches...!

also fixed two issues where we were 1) storing the short hash and 2) storing it
with a trailing "\n".  This diff makes us store the full hash AND no trailing
return character

Test Plan:
in my mercurial repo
<note repo at revision $foo>
<did something dumb>
hg commit -m "something dumb"
arc diff
<go to web and fill out stuff for DX>
hg checkout $foo
arc patch DX
<verify patch DX successfully applied!>

use conduit console to verify a few diffs were returning the correct full
revision hash with a trailing \n

c5dfa34f10 Add spell check linter
Summary:
Inspired by http://news.ycombinator.com/item?id=3464671 and a lot of
diffs I've seen @ FB, I've added a spell checking linter.  To reduce
false positives, it's only a blacklist.  Still, it catches a large
number of 'issues'.

Test Plan:
Unit tests.  Ran on FB's codebase.  No false positives
noticed but a lot of cases caught.

e5bda05200 Adds ArcanistJSHintLinter to check JS files for errors and potential problems.
This patch adds ArcanistJSHintLinter class and three new .arcconfig options:

 * lint.jshint.prefix - directory where JSHint binary resides
 * lint.jshint.bin - JSHint binary name (if different from 'jshint')
 * lint.jshint.config - a JSON file with JSHint project-wide options

By default, this linter assumes that JSHint is installed on user's system
as an NPM package.

Test Plan:

(1)

Run `npm install jshint -g` to install JSHint and add
ArcanistJSHintLinter to your Lint Engine (I didn't see PEP8 or
PyFlakes in the PhutilLintEngine so I decided to not to put
JSHint in there). After that you can do `arc lint my.js`.

(2)

Create a new file, config.json, and add `{ "white": true }` in it.
Add `"lint.jshint.config": "/path/to/config.json"` to your .arcconfig and
run `arc lint my.js`. After that, unless your name is Douglas Crockford,
you'll see tons of JSHint warnings about minor PEP8-like things (spacing, etc.)

f271e1d8e8 Improve 'arc' behavior under git mutable history with ambiguous commit messages
Summary:
Currently, we throw a fairly perplexing error when there are multiple valid
commit messages. Installs can also remove the "test plan" field entirely, which
is the only really strong discriminator here.

When the message to use is ambiguous, show the user all the valid messages and
prompt them to choose one.

Also add a -C flag like "git commit -C", so they can choose a message
explicitly.

Test Plan: Ran "arc diff HEAD^^^^^", "arc diff -C <rev>".

b61e4eacf1 Arc - add a sanity check to arc patch workflows to make sure the vcs base
revision is the correct base revision relative to the patch.

Summary: What the title says.   If not correct, warn the user.   This check
honors the --force flag to skip all these checks.   This change also includes
moving some Differential constants into Arc so they can be used for both
projects.   There is a corresponding phabricator diff (incoming) to address this
part of the change.

Test Plan:
For a project with actual diffs, a git repository tracked by phabricator, *AND*
development in master branch only, do some...
- git reset --hard HEAD^1
- arc patch DX, where X is what got us to HEAD in the first place
- verify successful patch
...then...
- git reset --hard HEAD^^
- arc patch DX, where X is what got us to HEAD in the first place
- verify warning
- verify Y versus N continues versus stops appropriately
Note if development were done outside the master branch this warning message
will fire early / often as git commit hashes are based on the commit *and* the
rest of the source code the commit is made against.  This is (unfortunately) the
"typical" case so this warning is pretty active at the moment.   T201 will
eventually land and when parsing a given commit update the corresponding diff.

560b339ad3 Refactor ArcanistDiffWorkflow to be a little more manageable
Summary:
I want to make some changes to this workflow but it a huge mess right now. Try
to refactor a bit to make it a little more manageable.

Broadly:

  - Moved lint/unit constant mapping into separate methods.
  - Moved lint/unit/local properties into separate methods.
  - Moved diff spec construction into a separate method.
  - Moved some message stuff into separate methods and reorganized related
methods near to one another.
  - Removed an unused findRevisionInformation() method.

I fixed a couple of small bugs, too:

  - --create now conflicts with --only and --preview.
  - --create now probably works in Mercurial.
  - --create messages now have basic reviewer validation.

This should have not have any significant behavioral changes.

Test Plan:
  - Created this revision.
  - Ran "arc diff --create".

62e527482b [arc svn-hook-pre-commit] Access working copy
Summary:
Creates a new hook API that can be used to interface with
SVN/Git/Mercurial in the context of a commit hook. Currently only adds a
function to read the modified file data in a Subversion commit hook.

An object of this API is created in the SvnHookPreCommitWorkflow and
passed on the Lint Engine which then uses it to access current file
data, of the way the APIs seem to be structured); linters use the
getData function which is essentially a wrapper around the engine's
call, with another layer of caching.

Task ID: #770556

Blame Rev:

Test Plan:
- Create a local svn repository and add a minimal hook to run the local
  version of arc to test commits

(http://phabricator.com/docs/arcanist/article/Installing_Arcanist_SVN_Hooks.html)
- Create a temporary repository that can trigger any of the linters
  available, and test against a temporary linter by committing against
  the test repository: the linter should be able to access all required
  files by using loadData/getData in the LintEngine and Linter.

6910fd77a4 Use getcwd() which is more reliable than $_SERVER['PWD']
Summary:
in arcanist we are using $_SERVER['PWD'], but in some cases it
is not returning the correct result. For example, when I'm using
PhpStorm (an php IDE) to launch the script, $_SERVER['PWD'] returns the
path of the binary of the IDE:
/home/jungejason/tools/PhpStorm-107.658/bin, not the path where arcanist
is at. getcwd() returns the correct value.

One difference between getcwd() and $_SERVER['PWD'] is that getcwd()
resolves symlink where $_SERVER['PWD'] does not. From what I can see,
using realpath should work.

Test Plan:
* ran arcanist as normal and it worked;
* run arcanist in PhpStorm and it worked.
* created a symlink pointing to the repository inside which
I ran the arc command, and it worked.
* created a symlink pointing to arcanist project, run `.
* resources/shell/bash-completion`  and it worked

25ebebe0df Bump Arcanist client version to 3
Summary:
Thinking about this, I think it's worthwhile to bump versions for T1249/T1250.
The problem is that if you have an old Arcanist, trying to update diffs against
a new Phabricator will create new diffs instead, and it probably won't be
obvious what's wrong.

Bump the versions so users will get a message like "oh, hey, you should
upgrade".

  - Tried to diff against a mismatched version.
  - Diffed against a matching version.

1f69ab5fdb Added local encoding parameter for arc diff workflow
Summary:
If any hunks is detected as non-utf8, and you've never submitted diffs
for a certain project before, you would get a ERR-BAD-ARCANIST-PROJECT
exception. This makes it possible to submit the patch properly, so you
can set the encoding in the interface afterwards. Further this fixes
cases where you don't supply a diff but will result in hunks getting
treated as binary, but that still beats the exception behaviour.

Test Plan:
Ran `arc diff` with and without the new --encoding param and
got the expected results. Also ensured the diff (with non utf-8 hunks)
would be properly created even when no encoding is specified.

16caf63d98 make arc issue a warning if file upload fails during diff creation
Summary:
just a little try / catch action in ArcanistDiffWorkflow.

"Ideally, it would be good to flag these changes somehow so that "arc patch" can
issue the inverse warning (e.g., "This patch could not be completely applied
because some binary data was not uploaded.") but that hasn't come up in a real
use case yet."

I think a change w/ filetype of FILE_IMAGE || FILE_BINARY *and* no phid means
that the upload failed so there's no additional flag needed.  (True?)  however,
it would be easy enough to store metadata that explicilty stated whether or not
the file upload succeeded.

(also / related - i looked through the arc patch workflow a bit and i don't
understand how the svn codepath loads up the actual binary files...  for git,
toGitPatch => buildBinaryChange => getBlob is the right path )

Test Plan:
 - set 'storage.mysql-engine.max-size' to 0 in my conf, uploaded diffs with
files
 - noted in differential that it correctly detected images versus binary despite
file upload failing
 - noted in differential that images had some empty UI
 - reverted conf change, uploaded diffs with files
 - noted in differential file showed up
 - ran arc patch with DX, where DX had broken files
 - noted "Downloading binary data...

works regardless of whether the color extension is present.

5150252f91 Add very hacky encoding transformation support for arc
Summary:
Adds a secret, undoucmented "encoding" key to ".arcconfig" which makes a very
half-hearted effort to convert encodings. This is probably good enough that
Differential can be used for code review, but there will be issues with 'arc
patch', 'arc export', paste, maybe conduit stuff, Diffusion, and whatever else I
haven't thought of.

This also doesn't store the original encoding so anything converted like this
won't reasonably be able to be made to work with all that stuff in the future.

See T452 for a broader discussion of the issues involved.

Test Plan:
Short circuited the UTF-8 detection to always fail, had my files "converted"
from ISO-8859-1 to UTF-8.

@davidreuss: you can test this by applying this patch to arcanist/, adding
'"encoding" : "ISO-8859-1"' to your .arcconfig, touching some non-ASCII file,
and then running "arc diff".

Summary:
See T584. Git renders these types of changes somewhat unusually. Ensure they are
rendered as changes.

The fact that a symlink was replaced is not explicitly rendered (e.g., "This
path was changed from a symlink to a regular file."), but can be inferred from
the 'unix:filemode' property change that will accompany the changeset. We could
also make it explicit but this type of change is rare enough that it's probably
good enough as-is.

  - Ran unit test, which previously failed and now passes.

1da98a11f1 Correctly parse git diffs with an empty file at the end
Summary: A minor bug in the parser prevented it from handling git diffs where an
empty file appears at the end of the diff. Since git appends an extra newline,
we failed to jump into the '$line === null' block.

Test Plan: Ran unit tests. Generated a revision which only deleted an empty
file.

2fd37a1728 Automatically detect when to mark revisions committed
Summary:
See D945. We have this kludgy "remote_hooks_installed" mess right now, but we
have enough information on the server nowadays to figure this out without it.

Also reduce code duplication by sharing the "mark-committed" workflow.

This causes "arc merge" to effect commit marks.

Test Plan:
In Git, Mercurial and SVN working copies ran like a million
amend/merge/commit/mark-committed commands with and without --finalize in
various states of revision completion.

This change is really hard to exhaustively test because of the number of
combinations of VCS, revision state, command, command flags, repository state
and tracking state. All the reasonable tests I could come up with worked
correctly, though.

fe5355e4e4 Use full-length hashes in Mercurial local commit information
Summary:
Expand 12-character hashes to 40-character hashes so other things will work
properly.

Also use "hg id" instead of "hg summary" to figure out where the working copy
is, since it's substantially simpler.

44959afd4b Add an "arc merge" workflow
Summary:
This should support conservative rewrite policies in git fairly well, under an
assumed workflow of:

  - Develop in local branches, never rewrite history.
  - Commit with "-m" or by typing a brief, non-template commit message
describing the checkpoint.
  - Provide rich information in the web console (reviewers, etc.)
  - Finalize with "git checkout master && arc merge branch && git push" or some
flavor thereof.

This supports Mercurial somewhat. The major problem is that "hg merge" fails if
the local is a fastforward of the remote, at which point there's nowhere we can
throw the commit message. Oh well. Just push it and we'll do our best to link
them up based on local commit info.

I am increasingly forming an opinion that Mercurial is "saftey-scissors git".
But also maybe I have no clue what I'm doing. I just don't understand why anyone
would think it's a good idea to have a trunk consisting of ~50% known-broken
revisions, random checkpoint parts, whitespace changes, typo fixes, etc. If you
use git with branching you can avoid this by making a trunk out of merges or
with rebase/amend, but there seems to be no way to have "one commit = one idea"
in any real sense in Mercurial.

Test Plan: Execute "arc merge" in git and mercurial.

9df1b8a4bd Improve Arcanist Mercurial compatibility
Summary:
  - Use "hg parents" to figure out where outgoing changes originate from, not
"~1", since that's a new feature in Mercurial.
  - Add "--style default" all over the place since hg config can override this
(similar to the date config issues we saw in git).
  - Cache working copy status so we don't run full hg diffs like 30 times
(similar to git/svn APIs).
  - Use full "--git" flag instead of rather cryptic "-g".

Test Plan: Ran "arc diff" in my hg working copy, got the diff I expected.

   we store some information (unit test results) in the engine that we

2) make requireCleanWorkingCopy() public

   "arc unit" doesn't need to be clean in general, but we'd like the
   option to upgrade the workflow to require it if necessary.  We use
   this for ensuring a repo is clean before updating unit test
   results.

4c05dc3cd6 Change patch generation for moving a file
Summary:
The unix utility `patch` will not move a file (unless it is in or out of
/dev/null). If a diff copies or moves a file and also makes changes to the file,
the generated patch needs to list the new filename as the path to both the
original and new files so the changes get written to the new file.

(When arc applies this patch, it copies or moves the original as needed before
running `patch`.)

(This only matters for svn repos, since arc uses git commands for git repos
instead of using `patch`.)

Test Plan:
Created an arc bundle of a diff that copied a file to a new location and made
changes in both locations, and then ran arc patch with this bundle (in an svn
repo) to see that it correctly patches.
