hgweb: simplify internal staticfile return codes

spelling: fix some minor issues found by spell checker

bundlerepo: replace basemap with the base field in the index Bundle revisions had some info in their fake revlog intries and some info in a dict with all the bundle revisions. This dict was used to get the stored data and to distinguish repo revisions from bundle revisions. Real repo revisions and bundle revisions will now be distinguished by comparing with the tip revision of the original repo. This reintroduces something similar to disktiprev which was unused and removed in a928865b4a4f and let that replace the O(reposize) dict.

profiling: replace '+' markup of nested lines with indentation The display of nested lines for hg --profile was very non-obvious and made it look like sort didn't work. The '+' immediately before CallCount was not related to the CallCount and did not mean plus in any integer sense. The '+' before module looked like a part of the module name and not like ascii art. Instead we now indent the subordinate module names to clearly show the structure.

Merge crew and main.

merge: don't fiddle with name lookups or i18n in hot loops We perform attribute dereferences and i18n lookups before looping.

merge: apply non-interactive working dir updates in parallel This has a big effect on the performance of working dir updates. Here are the results of update from null to the given rev in several repos, on a Linux 3.2 system with 32 cores running ext4, with the progress extension enabled. repo rev plain parallel speedup hg 7068089c95a2 0.9 0.3 3 mozilla-central fe1600b22c77 42.8 7.7 5.5 linux-2.6 9ef4b770e069 31.4 4.9 6.4

worker: allow a function to be run in multiple worker processes If we estimate that it will be worth the cost, we run the function in multiple processes. Otherwise, we run it in-process. Children report progress to the parent through a pipe. Not yet implemented on Windows.

worker: partition a list (of tasks) into equal-sized chunks

worker: estimate whether it's worth running a task in parallel Not implemented for Windows yet.

worker: count the number of CPUs This works on the major platforms, and falls back to a safe guess of 1 elsewhere.

tests: getremove test output changes (fold into previous patch)

merge: report non-interactive progress in chunks Instead of a monotonic count, getupdates yields the number of files it has updated since it last reported, and its caller sums the numbers when updating progress. Once we run these updates in parallel, this will allow worker processes to report progress less often, reducing overhead.

merge: handle subrepo merges and .hgsubstate specially In an upcoming patch, we will update .hgsubstate in a non-interactive worker process. Merges of subrepo contents will still need to occur in the master process (since they may be interactive), so we move that code into a place where it will always run in what will become the master process.

tests: update test output (will be folded into parent)

merge: split out mostly-non-interactive working dir updates In a later patch, we'll run these updates in parallel.

extensions: obsolete and remove interhg extension With the addition of the websub filter extension this extension is no longer needed. We maintain a sort of backwards compatibility by reading the [interhg] section and using it as we would use the [websub] section.

hgweb: apply the websub filter to revision descriptions In order to use this, add a [websub] section to your configuration and add websub expressions such as: italic = s/\b_(\S+)_\b/<i>\1<\/i>/ bold = s/\*\b(\S+)\b\*/<b>\1<\/b>/ issues = s|issue(\d+)|<a href="http://bts.example.org/issue\1">issue\1</a>|i bugzilla = s!((?:bug|b=|(?=#?\d{4,}))(?:\s*#?)(\d+))!<a href="http://bz.selenic.com/\2">\1</a>!i This also adds documentation (proofed by Kevin!) to the config help section.

hgweb: add websub template filter The purpose of this new filter is to make it possible to partially replace the functionality of the interhg extension. The idea is to be able to define regular expression based substitutions on a new "websub" config section. hgweb will then be able to apply these substitutions wherever the "websub" filter is used on a template. This first revision just adds the code necessary to load the websub expressions and adds the websub filter, but it does not add any calls to the websub filter itself on any of the templates. That will be done on the following revisions.

addremove: don't audit the path for paths already in the dirstate Now that dirstate.walk returns None for paths under symlink directories, addremove doesn't need to validate each path it sees to look for files under symlinks. On a large repository this brings addremove from 6.3 seconds down to 3.65 (42%) since addremove no longer has to stat every directory of every file to determine if the file is inside a symlink directory. I put it through our benchmark and see no perf hit to any other commands.

dirstate: walk returns None for files that have a symlink in their path Previously dirstate.walk would return a stat object for files in the dmap that have a symlink to a directory in their path. Now it will return None to indicate that they are no longer considered part of the repository. This currently only affects walks that traverse the entire directory tree (ex: hg status) and not walks that only list the contents of the dmap (ex: hg diff). In a situation like this: mkdir foo && touch foo/a && hg commit -Am "a" mv foo bar ln -s bar foo 'hg status' will now show '! foo/a', whereas before it incorrectly considered 'foo/a' to be unchanged. In addition to making 'hg status' report the correct information, this will allow callers to dirstate.walk to not have to detect symlinks themselves, which can be very expensive.

pathauditor: add check() method The pathauditor currently throws exceptions when it encounters an invalid path. This change adds a method to allow people to treat it as a boolean. This is currently used by scmutil.addremove and in a subsequent patch it will be used by dirstate.walk

summary: add missing space for updated active bookmark display

summary: show active bookmark even if not at current changeset Before this change, 'hg summary' would not show the active bookmark unless it pointed to the working directory parent. After this change, it will show it in parentheses, like so: parent: 18581:f0ff45fe6700 tip summary: simplify handling of active bookmark branch: default bookmarks: [crew] commit: (clean) update: (current)

summary: simplify handling of active bookmark

summary: test that current bookmark isn't shown This exposes the current behavior in a test. A later change will make summary show when the active bookmark has moved out from under us.

outgoing: fix possible filtering crash in outgoing (issue3814) If there is no outgoiing changesets but we have filtered revision in outgoing.excluded We run into a filtering related crash. The excluded revision should not be there in the first place but discovery need cleanup in default, not stable.

test: display used python hash seed We keep using a random seed for each run, but we "compute" it ourself to be able to reproduce a failed test run.
