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
