localrepo: iterate over manifest key/value pairs in status This saves us a couple of dict lookups in the common case, and improves the performance of the status method by 5% (measured with util.timed) in a repo with a large manifest.

match: more accurately report when we're always going to match This improves the performance of log --patch and --stat by about 20% for moderately large manifests (e.g. mozilla-central) for the common case of no -I/-X patterns.

scmutil: fix NameError on windows Forgot to import util in mercurial.scmwindows. Error was introduced in: changeset: 18862:4c6f7f0dadab user: Kevin Bullock <kbullock@ringworld.org> date: Tue Feb 12 11:36:21 2013 -0600 summary: scmutil: split platform-specific bits into their own modules

commands: exit from the log loop at the right time Previously, we'd run the iterator one more time than necessary, potentially doing a lot of extra work in the process.

cmdutil: use a small initial window with --limit In a large repo, running a command like "log -l1 -p" was expensive because it would always traverse 8 commits, as 8 was the initial window size. We now choose the lesser of 8 or the limit, speeding up the "log -l1 -p" case by a factor of 5.

worker: handle worker failures more aggressively We now wait for worker processes in a separate thread, so that we can spot failures in a timely way, wihout waiting for the progress pipe to drain. If a worker fails, we recover the pre-parallel-update behaviour of failing early by killing its peers before propagating the failure.

worker: fix a race in SIGINT handling This is almost impossible to trigger due to the tiny time window involved.

worker: on error, exit similarly to the first failing worker Previously, if a worker failed, we exited with status 1. We now exit with the correct exit code (killing ourselves if necessary).

largefiles: don't cache largefiles for pulled heads by default After discussion, we've agreed that largefiles for newly pulled heads should not be cached by default. The use case for this is using largefiles repos with multiple remote servers (and therefore multiple remote largefiles caches), where users will be pulling from non-default locations on a regular basis. We think this use case will be significantly less common than the use case where all largefiles are stored on the same central server, so the default should be no caching. The old behavior can be obtained by passing the --cache-largefiles flag to pull.

bundle: treat branches created newly on the local correctly (issue3828) Before this patch, "hg bundle --branch foo other" fails to create bundle file, if specified "foo" branch is created newly on the local repository. "hg bundle" uses "hg.addbranchrevs(repo, other, ...)" to look branch names up, even though other outgoing-like implementation uses "hg.addbranchrevs(repo, repo, ...)". In the former invocation, "other" repository recognizes such branches as unknown, so execution is aborted. This patch uses "hg.addbranchrevs(repo, repo, ..)" in "hg bundle" to bundle revisions on such branches correctly.

mergetools: refine vimdiff warning message We explicitly redraw before echoing the message so that it simply displays at the bottom of the window. Also simplifies the message printing by using 'echomsg' (which uses 'echohl' internally) and adds the names of the software involved for improved Googleability.

mergetools: vimdiff issue a warning explaining how to abort Adds a message displayed at each vimdiff invocation: merge conflict detected, type ":cq" to abort Vimdiff is very confusing for non-vim user (not to speak about vim user confused anyway. However it is very likely that vimdiff is picked as the mergetool of choice when using the default config: - vim is available on all UNIX system. - Its one of the rare non graphical merge tools.

httppeer: improve protocol check Pre-0.6c hgweb used text/plain for protocol responses. This meant that a web server could serve a static file and confuse a client into generating a nasty traceback. Now we insist that text/plain protocol responses not include a Content-Length, which older hgweb didn't generate but will typically be produced for static files.

httppeer: avoid large dumps when we don't see an hgweb repo When we don't get an hgweb protocol response, we dump the response to the user for diagnostic purposes (it might be a cgitb message, for instance). But if we try to clone a bundle, we don't want to show the entire bundle in the error message. Also, we don't want fetch the full bundle multiple times during fallback. So we only fetch 1k here.

dispatch: also a separate warning message on aliases with --config As mentioned in bug 2043, --config is also not supported in an alias. So report this the same way as the other "early" options. Example with alias.broken = stat --config a.config=1 Before: $ hg broken abort: Option --config may not be abbreviated! After: $ hg broken error in definition for alias 'broken': --config may only be given on the command line

extensions: remove erroneous comment We actually -do- use the 'ui' argument to print a debug statement.

blackbox: do not translate the log messages User 'timeless' in irc mentioned that having the blackbox be translated would result in logs that: - may be mixed language, if multiple users use the same repo - are not google searchable (since searching for english gives more results) - might not be readable by an admin if the employee is using hg in his native language And therefore we should log everything in english.

scmutil: split platform-specific bits into their own modules This parallels what's done for the util module, which imports either mercurial.posix or mercurial.windows as 'platform' and then slurps the appropriate functions into its own namespace.

backout: call cmdutil.commit directly instead of commands.commit This cleans up the messiness of having one command call another, and makes the backout command robust against changes to the commit command.

commit: factor out status printing into a helper function We create a new function commitstatus() in cmdutil that handles printing the status message(s) after a commit. This will allow other commit-like commands to use it, and in particular is step 2 towards removing backout's call to commands.commit.

backout: remove unnecessary dict copy This is step 1 to remove backout's call to commands.commit. We don't use the options again anywhere below except for backout's own purposes, specifically choosing a merge tool, so we just write the commit options in directly.

backout: remove unnecessary frobbing of addremove option There's no way for addremove to show up in backout's opts dictionary. It was being set manually because cmdutil.commit expected it to be there (and would throw an exception if it wasn't). This was fixed waaaaaaay back in: changeset: 5829:784073457a0f user: Kirill Smelkov <kirr@mns.spb.ru> date: Thu Jan 10 12:07:18 2008 +0300 summary: cmdutil.commit: extract 'addremove' from opts carefully

backout: use cmdutil.revert directly instead of commands.revert Before this change, backout would explicitly set the options it passed to commands.revert in order to fall thru most of its logic and call cmdutil.revert. This change makes it clearer what backup is trying to accomplish and makes it robust against changes to the revert command.
