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.

Test Plan: Ran unit tests.

7bb8dbabce Reduce the strength of "arc executing on arc" from an error to a warning
Summary:
See PHI13. This was introduced a very, very long time ago in D311 and D312, and I think T168 was the original report.

It prevents `arc` from being used in some semi-reasonable (maybe?) automation workflows where you're hooking some version of "Land Revision" up to `arc land`. This isn't necessarily the right approach, but I think the concession here to make this work is small.

Running `arc` against another copy of `arc` makes `arc unit` not work, but we provide a good error message. Most other `arc` operations still work correctly.

All of these situations are bizarre edge cases but I think we can safely warn and continue here. Even if we revert this behavior later, almost no one should be affected, since this essentially only impacts users developing `arc` itself.

Test Plan: Ran one copy of `arc` against another, saw a warning instead of an error. `arc unit` failed, but with a good error.

`PhutilConsole->confirm()` is vestigial as noted in efcd70c, as

Replace existing occurences of the `PhutilConsole->confirm()` pattern with
`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.
Grepped for affected flags/symbols.

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

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.

Test Plan:
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.

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.

Test Plan: Ran `arc lint` on Windows.

9e82ef979e Added a warning prompt if the user tries to use an API cert instead of a CLI cert
Summary: Fixes T9692. Instead of disallowing API tokens entirely, we're going to just warn the user that they might not want to do that. After that, they can proceed if they want to.

Test Plan:
Run arc install-certificate.
Manually go to `Settings → Conduit API Tokens` in the web UI.
Generate an API token explicitly, which should have the form api-******.
Paste that into the prompt on the CLI.
It will give you a warning prompt then ask if you'd like to proceed anyway (defaults to No).

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 @@
+data

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.

Fixes T11435. This isn't a perfect solution since there's a little code duplication, but a perfect solution is probably a bit more involved.

See T11435 for some discussion. In particular, most `git diff` commands already get this flag via `ArcanistGitAPI->getDiffBaseOptions()`.
