Auditors: jamesr, btrahan
Summary:
This implements Arcanist support for the xUnit testing framework. It also supports code coverage by way of `cstools` (which is something I've written).
The unit test support works under both Linux and Windows, while the code coverage support has only been tested under Linux (one would assume it would also work under Windows given that Windows has a super-set of functionality in the C# world).
The Arcanist support assumes that the directory layout will be something like:
* MyProject
* MyProject.Tests
When files are changed in either MyProject or MyProject.Tests, it causes MyProject.Tests to be built and the xUnit runner to be executed on the resulting binary.
Test Plan: I guess if really wanted to, you could create a C# project in MonoDevelop, set up `.arcconfig` to point to this unit test engine, and download and build xUnit and cstools. Run `arc unit --coverage` to see the results of your unit test coverage.

Fixes T3856.
Detailed code coverage iterates over all of the files with changes in the current repository, however the code coverage tool might not generate a report for all changed files in the repository, and this would result in an undefined index error.
As an additional bonus, since changes to binary files won't be reported by code coverage tools, this also prevents binary data from being outputted to the console.
Test Plan:
Change a binary file in a repository and run a code coverage tool. The binary file should be reported as 0% code coverage, but the file contents should not be rendered to the console.

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.

# 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.

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).
