named the same as a file path.
Summary: (In fbcode and www at least, the only places I tried) if a
branch happens to be named the same as a file path (from root) (like if
a branch is called `spec` and there is a directory in `www` called
`spec`) then `arc land` will fail with git complaining that the argument
(to `git log ...`) is ambiguous as it could refer to both a path and a
revision; so this diff adds a `--` to the end so that git knows that
both are revisions and not paths.
Test Plan: Try and land something from www (I did, see D752219) where
the branch is named `spec`.

Arc lint for git is currently adding all untracked files when it
amends the commit with lint fixes. This changes the git add -A to be

Summary:
This adds a arcconfig setting to allow specifying whether to use the merge
or rebase strategy when doing the feature branch update.
arc.land.update.default can be set to either 'rebase' or 'merge'. The command
line flags will override this setting.
We have had trouble with arc land producing merge commits (introduced
with D4080) in git. They usually appear when arc land fails, and our users
are confused by the presence of a merge commit afterwards. Today it got even
worse since a user managed to get arc land to push the merge commit to the
server. This setting will allow us to turn it off for our uses.
Test Plan:
Verified the following combinations:
update.default not set + arc land (saw git merge in the trace)
update.default = 'rebase' + arc land (saw git rebase)
update.default = 'merge' + arc land (saw git merge)
update.default = 'rebase' + arc land --update-with-merge (saw git merge)
update.default = 'merge' + arc land --update-with-rebase (saw git rebase)

Summary:
The `emailuser` template is a relatively recent addition to Mercurial, and a few users have complained about it. It also doesn't actually do what I thought it did, e.g. in an address like this:
"Abraham Lincoln" <alincoln@whitehouse.gov>
^^^^^^^^^^^^^^^ ^^^^^^^^
(1) (2)
^^^^^^^^^^^^^^^^^^^^^^^
(3)
...I want (1), but `emailuser` means (2). Instead, extract (1) with `getDisplayName()` and (3) with `getAddress()` using PhutilEmailAddress.
The implementation in Mercurial is not particularly sophisticated or magical (it just looks for "@" and "<") so we aren't really missing anything by doing this ourselves, at least today.
Also fix some issues in `arc export`, which literally no one uses, but which is occasionally useful for testing (as here).
Test Plan:
- Ran `arc diff --only` in an `hg` repo, checked DB to see that name/email were correctly extracted.
- Ran `arc export --git` in an `hg` repo, didn't get a long series of fatals.

Arc land is a bit magical and some users have gotten bitten by
the fact that it collapses and lands every commit on the branch. To make

print the commits that would be landed, but does nothing else.

Summary:
Previously, arc patch would create a new commit under the existing
current bookmark in mercurial. There have been two discussions about what the
right behavior should be (D3334 and D3658). One side wants no commit at all,
and one side wants a commit under a new bookmark. The current implementation is
the worst of both worlds :(
This change makes it create a new bookmark at the revision's base before commiting,
same as the --bookmark flag used to do (which is now obsolete). That way the
existing bookmark doesn't move (in mercurial >=1.8). This is the same behavior
git has, which is convienent for groups migrating between the two.
Also makes hg's getCanonicalRevision handle svn revisions just like git. This way
arc patch will try to apply the patch to the appropriate revision in the history.
Test Plan:
Ran:
arc patch - Verified it created a new bookmark and commited on top of the
revision's base commit.
arc patch --nobranch - Verified it put the new commit on top of the current
bookmark without a new bookmark.
arc patch --nocommit - Verified it left all the changes in the working copy.
Also verified arc patch still works with git.

Summary:
- Added arc.autostash option to have this behaviour off by
default (but configurable on a per-project basis).
- Automatic stashing of changes now informs the user of how
to restore their working directory if Arcanist unexpectedly
terminates.
- Fixed an issue with finalizeWorkingCopy when the workflow
didn't require a clean working copy.
Test Plan:
Test `arc diff` when there are changes in the working
directory; by default it should tell you to stash or commit.
Turn on the arc.autostash option and try again; it should
automatically stash with a message on how to recover, and
it should restore the working directory automatically under
almost any circumstances (other than an unrecoverable error).

Summary:
Adds error handling for several kinds of failure in arc land for
mercurial. Previously it would often leave the repo in a confusing state
if something failed.
- Aborts the land if pull brings in a diverged 'onto' branch.
- Aborts the rebase if there is a conflict. This leaves the repo exactly as
it was before, so the user is not left with a half finished rebase.
- Don't delete the original non-squashed branch until the push succeeds.
- If the push fails, strip the temporary squashed commit. This leaves the
'onto' branch back on the latest commit from the server, and leaves the users
original nonsquashed branch around.
- Always leave the user back on their original branch after an error.
Test Plan:
Ran arc land:
- with pull causing a diverged 'onto' bookmark
- with the 'onto' bookmark already diverged
- with the rebase causing conflicts
- with a push that failed due to a commit hook
- with a successful land
- with a successful collapse and land
In all failure cases the repo was left exactly as it was before arc land,
except for the push-failed case, where the only change was that the branch
was correctly on top of the destination branch due to a successful rebase.
Used bookmark name "foo bar-gah" to test that crazy bookmark names still work.

Summary:
Previously, running arc lint on a set of changes that only
existed in your working copy threw an exception in mercurial repos.
It was trying to use the revset "...." (i.e. the range from . to .),
which didn't parse. Even if I fix that it still doesn't work because
getRawDiffText did not include the working copy changes (which it does
in git). I removed the check so the function now acts the same as in
git and arc lint works on working copy changes. I've seen this error before
in other places so hopefully this change will also fix any other areas,
that depended on getRawDiffText working the same as git.
The logic I removed was added in D1954 to support diffing against
uncommited changes. That workflow should be unchanged. arc diff will
still prompt the user if there are uncommited changes, and the user can
still choose to abort or continue.
Let me know if I missed something important which makes this a bad idea.
Test Plan:
Edited a file in the working directory of a hg repo.

Summary:
Mercurial 'arc land --hold' was taking 90+ seconds on our large
repository. Since most of arc land doesn't require any particular working
directory, I've changed the mercurial logic to avoid all updates except for
two: the one prior to finding the revision (only applies if the user specified
--branch), and the one at the end to leave the user in a good state.
Also got rid of a 'hg outgoing' call when phases are supported. Also changed
the hg-subversion detection to just look for .hg/svn instead of running 'hg
svn info', which was taking 4 seconds.
Now arc land takes about 50 seconds. Still much worse than git's 25 seconds.
One big hot spot is in the two 'hg rebase' calls, which account for 25 seconds
(versus 11 seconds of git).

Tested arc land with mercurial and git. Tested with and without the --branch
