8bbcbdd3b6 Prompt users to ignore or abort on untracked files
Summary:
Fixes T7521. This separates things into two prompts and doesn't try to automatically add untracked files.

This also fixes T7512, or at least I can't reproduce it after this change.

Test Plan:
  - Ran `arc diff` in a `git` directory with untracked files.
  - Ran `arc diff` in a `svn` directory with untracked files.
  - Ran `arc diff` in a `hg` directory with untracked files.

1a2829d281 Fix chunk upload fallback behavior
Summary:
Ref T7594. Currently, if a chunk upload fails, we incorrectly swallow the failure and fall back to single-file upload, which will often fail by hitting size limits. This also silences the original error.

Instead, do chunk uploads outside the block so that any exceptions escape, and we don't try to fall back to single-file upload.

Mostly just trying to get more info about what's going wrong on @joshuaspence's install.

Test Plan: Faked an exception in chunk upload, ran `arc upload` on a big file, saw the exception displayed on the console.

3d871b4214 Add untracked files to commit using prompt
Summary:
Refs D11990. When using `arc diff` with untracked files in the working
copy, add the untracked file(s) to the commit (as they weren't stashed or
ignored). Add the untracked paths to the list of changes in the editor
template, indicating that the files were added to the commit.

This doesn't add a separate prompt to add untracked files as per the
behaviour prior to D11843.

Test Plan:
Ran `arc diff` with only untracked files, answered yes to the 'create
new commit' prompt. Saw the commit-message with the updated changes
including untracked files. Completed the arc template, and got commit
containing uncommitted, unstaged and untracked files.

5c20df1818 Arcanist / Conduit - stop using deprecated diffusion.getcommits
Summary: Fixes T7113. This one was a bit trickier than others as the API output changed a bit. In particular, there is no "errors" emitted so much as the result set just doesn't include the answer if things are garbage. Ergo, check the "identifier map" to either check for diff existence or to lookup the phid to grab the actual diff data from the "data" part of the result.

Summary: Instead of having an `ArcanistWorkflow` subclass explicitly throw an exception when run in an unsupported VCS, consolidate this code and move it to `arcanist.php`.

We could consider adding a `getUnsupportedRevisionControlSystemMessage()` method to provide a more tailored error message. Depends on D11604.

1b8ce98304 Pass conduit credentials down to children workflow
Summary:
Calling `arc patch` on a diff that's dependent on a different diff tries to patch the parent first.
To patch the parent a child workflow is created, and a conduit is passed down, but the credentials are not and it is not marked as authenticated.

Then when the child tries to get the commit message for the dependency, it checks isConduitAuthenticated() https://secure.phabricator.com/diffusion/ARC/browse/master/src/workflow/ArcanistPatchWorkflow.php;2c3268f03ed70d3221eb1642bIc99ebb39b12902e$800 and on failure pops up an interactive editor for the commit message.

Instead we just pass down the credentials to the childred and mark them as authenticated, so this is not a problem.

Test Plan: With two diffs where DA2 depends on DA1, run `arc patch --force --nobranch DA2` ... this no longer pops an interactive editor for the commit message for the dependency.

ac62f28f19 Schedule repository updates from arc commit, not just arc land
Summary: Ref T5926. We only pass Phabricator an update hint from `arc land`, not from `arc commit`.

Test Plan:
  - Ran `arc land` and `arc commit` with `--trace`, saw hints go over the wire.

54bea946c1 Remove --background flag to prevent arc from hanging
Summary:
Ref T4281. A long time ago, we added a `--background` flag to let `arc lint` and `arc unit` run while you're typing a commit message, in some situations.

This code is only moderately beneficial and is way too complicated. Particularly, it has a long history of causing hangs (T4281, T2463), doesn't work on Windows, and is impossible to debug.

It's also running into a serious PHP bug with EAGAIN/EPIPE being indistinguishable that I haven't been able to find a reasonable workaround for in ~3-4 hours of trying.

All the pathways forward that I can see make this already-complex system more complex.

The major reason that this stuff is so complex is that the subprocess may need to prompt the user (notably, to apply patches from lint).

Instead, I'm going to simplify how `arc diff` interacts with `arc lint` and `arc unit`, so we can just fire-and-forget a background process, let it do as much work as it can without needing user input, and then pick up wherever it left off. This will be slightly less cool/magical, but it won't hang bizarrely and I will be able to debug it.

For now, simply remove the `--background` flag and behavior so `arc` works for everyone.

Test Plan: Ran `arc diff` to create this diff.

377eb5d1e0 Don't interpret arc browse . as a commit
Summary: Ref T5781. `git show .` works like HEAD, but that isn't what `arc browse .` means.

Test Plan: Ran `arc browse .` with a repository at a published commit.
