Respect the DESTDIR variable during 'make install'
The DESTDIR variable used to tell 'make install' an alternate system root
to install the software to. Since setup.py supports the same via its --root
parameter, it's easy to make life easier for many packagers.
commands: add more robust support for 'hg log -b' (
issue2078)
Fixes
issue2078 and adds tests to cover various 'hg log -b' uses.
This change adds a localrepo.lookupbranch(key, remote=None) function. This
will look up the branch of the revision with the given key. The algorithm
works like this:
* If a remote repo is given and KEY is the name of a branch in that repo,
return KEY.
* If no remote repo is given and KEY is the name of a branch in the local
repo object, return KEY.
* Otherwise look up the revision with the identifier KEY in the local repo
and return its branch.
This change also makes 'hg log -b' use this new functionality and adds a few
tests for it.
