0989343a4e Correct some lint console renderer issues with files missing trailing newlines
Summary:
See PHI162. This corrects a couple more bugs:

  - If the old file didn't end in a newline, we could end up printing two lines next to each other in the output.
  - If the patch targeted "Line 6, character 1" instead of "line 5, character 3" in a file "1\n2\n3\n4\n5\n", we would fail to figure out what that meant when computing an offset because the last line has 0 characters on it.

Test Plan: Added failing unit tests, made them pass. Also tested with some fake linters similar to the ones described in PHI162.

617c2e46d6 Make "line" and "char" strictly optional in ArcanistLintMessage
Summary: See PHI136. These are already optional on the server side in `HarbormasterBuildLintMessage`, and effectively mean "file-level issue", which is a bit niche but not unreasonable.

7af60b07cb Modularize "arc lint" renderers
Summary:
Ref T12996. `arc lint` can render in different formats with `--output <format>`.

Previously, these were a big `switch()` statement and a bunch of hard-coded stuff.

Modularize them so that that third parties could add new renderers, and this code can be refactored toward parallelizing the `lint` step.

This has a small behavioral change: we no longer hide "autofix" messages. I'd like to generally simplify the number of amend/autofix flags here, so this edges us toward that slightly.

Test Plan: Ran `arc lint` with all the `--output` flags in states with warnings and no warnings, saw sensible-seeming behavior.

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.

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.

Test Plan: Ran unit tests.

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

483e985d08 Check both UNIX- and Windows-style paths from linter output
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
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."

Fixes T11248.

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.

before this change.

22af67c1c0 Minor fixes to arcanist cpplint
Summary:
This fixes the regex in "getLintCode..." so that it accepts lint
codes such as `build/c++11` which have become valid lint codes
in later versions of cpplint.

It also corrects the install instructions for the linter (Google's
style guide is no longer available on SVN and has been migrated to
Github).

Test Plan:
For the Regex:
- Create an .arclint in a project such as:
```
{
  "linters": {
    "cpplint": {
      "type": "cpplint",
      "severity": {
        "build/c++11": "advice"
      }
    }
  }
}
```
- Run `arc lint` with the existing linter. This should fail. Patch the linter, and this should now be accepted.

For the Instructions
- Verify the download location `wget https://raw.github.com/google/styleguide/gh-pages/cpplint/cpplint.py`

560e4ae491 Add a linter rule for invalid octals
Summary: PHP doesn't handle octals very well. Basically, it seems that any numeric scalar matching `/^0\d+$/` will be treated as an octal, whereas this should be `/^0[0-7]+$/`. As a result, `08` and `09` are both treated as `0` (because they are invalid octals. This diff adds a linter rule to detect this abnormality.

Test Plan: Added unit tests.
