hgweb: make sure sys module is loaded prior to reload hack If sys is still a demandmod, reload(sys) fails with "TypeError: reload() argument must be module".

win32: improve the performance of win32.unlink() over CIFS Emulating POSIX unlink() behavior with os.rename() and os.unlink() is often slow especially over CIFS from Windows clients due to its protocol overhead. This patch changes win32.unlink() to try first an exclusive open with the Win32 delete-on-close flag, and if a sharing violation is detected, to fall back to the original emulation. This patch also removes a test with os.path.isdir() since we expect opening a directory shall fail as os.unlink() would.

revset: changed mfunc and getset to work with old style revset methods Now extensions shouldn't break when adding new revsets.

revset: changed revsets to use spanset Performance Benchmarking: $ hg perfrevset "first(all())" ! wall 0.304936 comb 0.300000 user 0.280000 sys 0.020000 (best of 33) $ ./hg perfrevset "first(all())" ! wall 0.175640 comb 0.180000 user 0.160000 sys 0.020000 (best of 56)

revset: changed spanset to take a repo argument This way, we can have by default the length of the repo as the end argument and less code has to be aware of hidden revisions.

journal: report parsing errors on recover/rollback (issue4172)

rebase: do not try to reactivate deleted divergent bookmark If the currently active bookmark is divergent one, it may be resolved during rebase. Trying to activate it will raise "KeyError: 'W@diverge'".

tests: backout 00f2d29308db pid check

revset: changed spanset implementation to take hidden revisions into account Hidden revisions are now excluded from the spanset. Now this doesn't break for people using changeset evolution.

template: add 'current' to scope during {bookmarks % ...} This adds the keyword 'current' to the template scope when processing a bookmark list. The 'current' keyword resolves to the name of the currently active bookmark in the repo. This allows us to apply special labels to the current bookmark to distinguish it (especially in the case where there are multiple bookmarks on the same commit). Example: "{bookmarks % '{bookmark}{ifeq(bookmark, current, \"*\")} '}" Results in a space separated list of bookmarks where the current bookmark has an asterix.
