dirstate: disable gc while parsing the dirstate This prevents a performance regression an upcoming patch would otherwise introduce because it indirectly delays parsing the dirstate a bit.

export: show 'Date' header in a format that also is readable for humans 'export' is the official export format and used by patchbomb, but it would only show date as a timestamp that most humans might find it hard to relate to. It would be very convenient when reviewing a patch to be able to see what timestamp the patch will end up with. Mercurial has always used util.parsedate for parsing these headers. It can handle 'all' date formats, so we could just as well use a readable one. 'export' will now use the format used by 'log' - which is the format described as 'Unix date format' in the templating help. We assume that all parsers of '# HG changeset patch'es can handle that.

factotum: fix urllib2 import so it no longer relies on a demandimport bug demandimport will do that urllib2 can be imported 'from mercurial' even though it doesn't exist there.

hgweb: make the test suite use hgweb in a more WSGI compliant way - as checked by wsgiref.validate. This makes sure that we don't optimize hgweb for invalid use cases.

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.
