localrepo.getbundle: drop unused 'format' argument
The 'format' argument was not used even when it was added in
60ad2ea5b106 (getbundle: pass arbitrary arguments all along the call
chain, 2014-04-17).
Note that by removing the argument, if any caller did pass a named
'format' argument, we will now pass that along to exchange.getbundle()
via the kwargs. If the idea was to remove such a key, that should have
been done explicitly.
exchange: remove check for 'format' key
When the 'kwargs' variable was added in
12f161f08d74 (bundle2: allow
pulling changegroups using bundle2, 2014-04-01), it could contain only
'bundlecaps', 'common' and 'heads', so the check for 'format' would
always be false. Since then, _pullbundle2extraprepare() has been added
for hooks, but it seems unlikely that they would a 'format' key.
templates-default: do not show description or summary if empty
changeset_printer shows description only if ctx.description().strip() is not
empty. The default template should do the same way.
treemanifest: further optimize treemanifest.matches()
The matches function was previously traversing all submanifests to look for
matching files, even though it was possible to know if a submanifest won't
contain any matches.
This change adds a visitdir function on the match object to decide quickly if
a directory should be visited when traversing. The function also decides if
_all_ subdirectories should be traversed.
Adding this logic as methods on the match object also makes the logic
modifiable by extensions, such as largefiles.
An example of a command this speeds up is running
hg status --rev .^ python/
on the Mozilla repo with the treemanifest experiment enabled.
It goes from 2.03s to 1.85s.
More improvements to speed from this change will happen when treemanifests are
lazily loaded. Because a flat manifest is still loaded and then converted
into treemanifests, speed improvements are limited.
This change has no negative effect on speed. For a worst-case example, this
command is not negatively impacted:
hg status --rev .^ 'relglob:*.js'
on the Mozilla repo. It goes from 2.83s to 2.82s.
util: move dirs() and finddirs() from scmutil to util
An upcoming commit requires that match.py be able to call scmutil.dirs(), but
when match.py imports scmutil, a dependency cycle is created. This commit
avoids the cycle by moving dirs() and its related finddirs() function from
scmutil to util, which match.py already depends on.
parsers: remove unused dependency on util
Parsers.py had a reference to util.sha1 which was unused. This commit removes
this reference as well as the unused import of util to simplify the dependency
graph. This is important for the next commit which actually relocates part
of a module to eliminate a cycle.
changectx.walk: drop unnecessary call to match function
If all the files in match.files() are in the context/manifest, we
already know that the matcher will match each file.
largefiles: use the share source as the primary local store (
issue4471)
The benefit of retargeting the local store to the share source is that all
shares will always have access to the largefiles any one of them commit, even if
the user cache is deleted (which is documented to be OK to do). Further, any
push into the source (and now any shares), will likewise make the largefile(s)
visible to all related repositories.
In order to maintain compatibility with existing repos, where the largefiles
would be cached only in the local share, fallback to searching the local share
if it isn't found at the share source.
The unshare command should probably be taught to copy the source store into the
store for the repo being unshared to complete the loop.
This patch changes the test like this:

The issue writeup mentions pushing a largefile from a remote repo to the main
local repo, and the largefile is then not available in any shares. Since the
push doesn't cache the largefile in $USERCACHE, the trashed $USERCACHE in this
test is equivalent.
