fb666f865e02 fixed gitlookup to work with upstream Mercurial, but we aren't
ready to deploy upstream Mercurial yet. So I'm backing it out so we can deploy
the fb-hgext rpms in the mean time.
Summary:
This adds an extension that tracks the locations of the working copy and
bookmarks over time. It's still a proof of concept, but I want to get it
deployed to start getting feedback.
Running `hg reflog` by default shows the previous locations of the working
copy (most recent first).
~/myrepo> hg reflog
Previous locations of '.':
35a5fcfee452 rebase -d master
32eee5e2d406 up .^
b5d6dab4f900 up foo -C
Specifying a bookmark name shows the locations of that bookmark over time.
~/myrepo> hg reflog foo
Previous locations of 'foo':
d1a696044ec0 rebase -d master
35a5fcfee452 rebase -d master
32eee5e2d406 book foo -f
--verbose will show more information about each entry.
~/myrepo> hg reflog foo -v
Previous locations of 'foo':
35a5fcfee452 -> d1a696044ec0 durham 2014-10-01 18:32:14 rebase -d master
32eee5e2d406 -> 35a5fcfee452 durham 2014-10-01 17:28:54 rebase -d master
000000000000 -> 32eee5e2d406 durham 2014-10-01 17:28:30 book foo -f
It's currently stored as a single .hg/reflog file that is append only. Each
entry can store an arbitrary number of hashes (like storing 2 hashes for a merge
state working copy), which means we could also potentially use this to track
heads in branches as well.
It also (sorta) works with '-T json' for machine readable output:
~/myrepo> hg reflog foo -T json

Summary:
sshing to the hg server could result in stdout containing 'remote: ...' (like if
the user had an extension enabled that wasn't on the server). This interefered
with fbmake being able to parse the git hash and broke fbmake for people with
such configs.
The fix is to redirect it to stderr instead. I tried using ui.push/popbuffer
but it doesn't actually work because the ui that is being used is newly
constructed as part of the peer being created, and therefore doesn't respect the
buffer stack. I also tried ui.quiet=True, but that also failed, as newly created
ui's don't inherit the original quiet value, but instead look at the main
config['quiet'].
Test Plan:
Added a bogus extension to my ~/.hgrc

hh log -r g988fa44ff4bebf4093b09ef27b5e24702ebda6ab 2>/dev/null
Verified there was no 'remote:' output.

Summary:
Previously, `hg grep` would follow symlinks because that's what `grep` does. This is a problem in fbcode because of all the tp2 and dewey symlinks. Handroll our iteration and ignore all files recorded as symlinks in the dirstate. This isn't perfect, but it's good enough and it's a lot faster than stating all the files.
Presumably we can integrate this with hgwatchman at some point.
Now, `hg grep <random string>` in fbcode takes just 2.6 seconds. (`git grep` takes 4.)
Test Plan: Ran tests.

Summary:
When doing 'hg unshelve foo.txt' with Changeset Evolution enabled, uncommit will
first prune the commit, then try to read the filelog history to determine if any
renames need to be undone. Since the commit is now pruned, remotefilelog fails
to find any valid histories.
This fixes it two allow hidden histories if the filectx commit is hidden. It
also tweaks remotefilectx to produce commit-relative histories when possible,
which will result in more accurate histories.
Test Plan:
Ran hg uncommit in the evolve repo that had problems before. Verified
it now worked.

Summary:
Pull-prefetch would not download file versions from the server if the file
version already existed in the local cache or the local store data.
Unfortunately, if someone landed their commit, then later stripped their local
version, the local store data file version might become invalid and no local
cache version would exist. Meaning things like 'commit' might fail when offline.
This changes prefetch to always fetch from the server when dealing with files it
knows are from revs on the server.
Test Plan:
Added a test that makes local commits that already exist on the
server, and verifies that a pull-prefetch fetches the server file version,
despite that same version existing locally.

Summary:
Previously we wrapped commands at global initialization time, which is just
plain wrong (since other commands may not have even be initialized yet). Now we
do it inside extsetup. It's mildly important that we do it in extsetup (vs
uisetup) because other extensions, like remotefilelog, wrap commands in the
uisetup and we want to make sure that our tweaks (like passing -f to log) come
first. And by wrapping last, we get invoked first.

Previously we were able to use ancestors.genericancestors to do the graph

unused), so remotefilelog must now build a temporary rev graph in order to use
the ancestors.* apis.

Summary:
Adds a wip extension which will allow clients to checkout
bookmarks from their peers instead of using arc patch.
This is accomplished by writing metadata about every
commit to a mysql database. When the user attempts to
checkout another user's bookmark, eg `hg checkout mjberger/test`,
the extension queries the mysql server to see if the bookmark
'test' exists on mjberger's dev server. If so, the extension
will use 'hg pull' to download the bookmark.
This is a wip and should not be used in production. Besides being
a hacky implementation, it currently relies on fbcode and does
not remove bookmarks from the mysql server when the client deletes
them.

Summary:
Previously, if pullprefetch was set, we'd perform a prefetch of the
entire manifest of the specified revs (usually the public bookmarks). This
involved stat-ing all the relevant files in the cache to see if they already
existed, which added an extra 6 seconds or so to every pull.
Now we only prefetch the files that are different from our working copy. We
assume we already have all the files that are in our working copy. This reduces
the pullprefetch overhead significantly.
