run-tests.py: work when --with-hg is set to system hg Previously we'd always assume that --with-hg is a script in a user directory, and would write out a 'python' symlink to the same location. That didn't work if --with-hg was set to a system installation of hg, e.g. /usr/bin/hg. Introduce a TMPBINDIR directory which is used to write out the python symlink.

revset: added cached generated list on generatorset This allows to iterate the generatorset more than once.

templater: shorten pure integers Originally, the addition of the 'shorten' template function in 9c6b86dd2ed2 would not consider pure integers for shortening. This patch considers two simple cases: when the integer starts with zero (which is parsed by Mercurial as a hash first) and when the integer is larger than the tip (obviously not a rev).

revset: fixed bug where log -f was taking too long to return

revset: added generatorset class with cached __contains__ method

pathencode: eliminate signed integer warnings Compiling mercurial with the Sun Studio compiler gives seven copies of the following warning on pathencode.c: line 533: warning: initializer will be sign-extended: -1 Using explicit unsigned literals silences it.

revset: changed last implementation to use lazy classes Instead of using getitem just reverse the revision list and get the first 'lim' elements. With classes like spanset which are easily reversible this will work faster. Performance Benchmarking: $ time hg log -qr "last(all())" ... real 0m0.569s user 0m0.447s sys 0m0.122s $ time ./hg log -qr "last(all())" ... real 0m0.215s user 0m0.150s sys 0m0.063s

help: remove last occurrences of ".. note::" without two newlines When we add two newlines after ".. note::" translators will not see this entry. And all versions of docutils interpret this paragraph correctly (details in de16c673455b).

help: add ifcontains, revset, and shortest to template help Adds help information to the template help doc. Mentions ifcontains, revset, shortest, and current in bookmarks.

verify: do not prevent verify repository containing hidden changesets Since a959f7167077, repo.cancopy() cannot be used to check if the repo is a bundlerepository. repo.url() should always have "scheme:", so it isn't necessary to parse by util.url().

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.
