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.

highlight: fix to work with caching templater

debugcomplete: don't list deprecated options

commands: Add 'hg log --branch' and deprecate 'hg log --only-branch' Switching to --branch makes log consistent with push/pull and make more sense given the actual behavior of the option (you can specify -b multiple times to include multiple branches). This change also adds some tests for 'hg log -b'.

bookmarks: complete the missing references from dda4ad7c9ea9 (issue2121) The fix for issue1611 left one last use of "repo" instead of "self" that has resulted in more memory leaks from push/pull operations.

Added support for 'pretxncommit', so that one can call the ACL hook at pre-commit time too. This is useful because now it's possible to avoid violating ACL permissions much sooner, at commit time, instead of waiting for a PUSH to check if there were any invalid commits.

subrepo: fix repo root path handling in svn subrepo

remoteui: copy http_proxy settings http_proxy settings of current repo's .hg/hgrc should be available on remoteui, so that the httprepo can use them when pulling via http.

dispatch: ignore if signals can not be set This happens if the code is executed in a thread. This patch allows tortoisehg to start the inotify server again.

hgweb: fix attribute error in error response (issue2060)

cvs: skip bad tags If the CVS repo somehow has a symbolic name that references a revision consisting of a single number (e.g. BAD_TAG: 1), convert will fail when attempting to find the branches, preventing the initial import from working. This patch skips those symbolic names--without warning.

document missing template variables

diffstat: use ui.plain() instead of ui.interactive() Previously, a default width of 80 is used for non-interactive sessions. This behaviour was introduced before HGPLAIN was supported.
