merge: fix UnboundLocalError (issue3791) A wrong variable name was introduced in 384df4db6520 for a case without test coverage. The variable name is fixed and a test case is introduced.

parsers: fix memleak of revlog cache entries on strip Since 12a852c7c763, raw_length can be reduced on strip, but corresponding cache entries still have refcount. They are not dereferenced by _index_clearcache(), and never freed. To reproduce the problem, run "hg pull" and "hg strip null" several times in the same process.

hgweb: fix navigation label (issue3792) Latest refactoring (6da1e979340a) was buggy and used a variable from another loop. Tests are run on repo too small to cache that.

profiling: add documentation of lsprof 'sort' and 'nested'

OS X: try cheap ascii .lower() in normcase before making full unicode dance This is similar to what is done in encoding.lower, introduced in c481761033bd. This has been seen making 'hg up' and 'hg st' in a 50000+ files repo 13% faster. This might make Mercurial slightly slower for users who mainly use non-ASCII filenames. That is a reasonable trade-off.

run-tests.py: inherit PYTHONHASHSEED from environment if set This makes it possible to fix the seed by using for instance PYTHONHASHSEED=7 ./run-tests.py ... This can be very convenient when trying to debug problems that are influenced by hash values. Try different seed values until you find one that triggers the bad behaviour and then keep that while debugging. The value 0 will restore default Python behavior and disable randomization.

test-obsolete: validate that bundle is not affected by issue3788 Bundle might have been affected by the same kind of error than pull (issue3788). Testing show it is not the case.

pull: fix crash when pulling changeset that get hidden locally (issue3788) When you have obsolescence marker that apply to a pulled changesets, the added changeset is immediately filtered. Then the list of added changeset needs to be build against and unfiltered repo.

hgweb: prevent traceback during search when filtered (issue3783) The search needs to iterate over the repo using changelog.revs like the rest of the Mercurial code.

bookmarks: hide bookmarks on filtered revs from listkeys Don't expose unserved changesets to remote repos. Thanks to Sean Farley <sean.michael.farley@gmail.com> for tracking down the issue and Pierre-Yves David <pierre-yves.david@ens-lyon.org> for the fix.
