subrepo: compare svn subrepo state to last committed revision A subversion project revisions are a subset of the repository revisions, you can ask subversion to update a working directory from one revision to another without changing anything. Unfortunately, Mercurial will think the subrepository has changed and will commit it again. To avoid useless commits, we compare the subrepository state to its actual "parent" revision. To ensure ascending compatibility with existing subrepositories which might reference fake revisions, we also keep comparing with the subrepo working directory revision. NOTE: not sure if this should go in stable or not.

merge with stable

win32: win32console.GetStdHandle() can return None When the Mercurial Python libraries are used within a Windows application with no console, there is no stderr file handle.

revlog: remove stray test in rev()

opener: use util.unlink (issue2524)

lock: use util.unlink (issue2537)

reintroduces util.unlink, for POSIX and Windows. windows: factor it out of rename posix: add alias 'unlink' for os.unlink Note that this new unlink function now has different semantics than the unlink() we had before changeset 6bf39d88c857 ("rename util.unlink to unlinkpath").

opener: check exception for ENOENT

windows.rename: check OSError for EEXIST For example, if src has been opened with Python's open(), os.rename will raise EACCES. Continuing in that case is pointless.
