posixfile_nt: '+' should allow read access.
This fixes unexpected I/O error on committing many files
due to cset:
8a53b39cd402 (r4902 in crew).
httprepo: quote the path part of the URL
This should fix a 'hg clone "http://hg.example.org/path with spaces/"'
The code tries to do the right thing when the user passes a path that's
already escaped in part (e.g. "http://hg.example.org/path%20with spaces/").
If we're redirected, urllib2 will happily follow the URL it's given
without escaping anything. I'm not sure what we would have to hook
to work around that.
dirstate: fix rebuild; add a test
If rebuild calls invalidate, it will just queue a (re)read of the dirstate
file, while what we really want is to empty the current state.
Simplify/correct finding the hg executable (fixes
issue644)
Simply use find_exe('hg') as the default value for $HG and require to manually
set it if you have special requirements.
While the default will not always be 100% correct (i.e. the identical hg
version) for many users it is and for the others the hg executable found in
the PATH should do most things correctly.
Developers or other users with multiple installs can set $HG or run something
like util.set_hgexecutable in their shell or python scripts.
Additionally util.hgexecutable() is now available so extensions can access
the value with a public interface, too.
archive: abort on empty repository. Fixes #624.
