annotate hgext/git/dirstate.py @ 46113:59fa3890d40a

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
node: import symbols explicitly There is no point in lazy importing mercurial.node, it is used all over the place anyway. So consistently import the used symbols directly. Fix one file using symbols indirectly via mercurial.revlog. Differential Revision: https://phab.mercurial-scm.org/D9480
