subrepo: use sharepath if available when locating the source repo This is an alternative fix for issue3518, enabling sharing of repositories with subrepos, without unconditionally setting the default path in the resulting repo's hgrc file. Better test coverage is added here, but won't prove this code is working until fd903f89e42b is backed out. The problem with the original fix is, if a default path is not available to be copied over from the share source, the default path on the resulting repo is set to the source location. Since that's where the actual repository is stored, the path is essentially self-referential, so push, pull, incoming and outgoing effectively operate on itself. While incoming and outgoing make it look like nothing was changed, push currently hangs (see issue3657). In this case where there is not a real default path, these operations should abort with "default(-push) not found", like the source repo would. Note this problem with the original fix affected repos without subrepos too.

test-histedit: add tests for dropping head changeset I got bug report from user in this specific case. I was unable to reproduce in test situation. Testing this situation is still valuable.

tests: use `pwd` instead of ${PWD} in test-convert-git.t - because of Solaris

histedit: prevent parent guessed via --outgoing from being a revset (issue3770) If the binary hash of the parent node guessed via --outgoing happened to contain a special revset character (":" was specified in the bug), the revset parser would abort. Hexlifying the node before passing it to the revsingle call should fix that.

tests: fix for windows - slashes and no serve

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.
