Some comments in this patch assume that subsequent patch changes 'dirstate.write()' like as below: def write(self, repo): if not self._dirty: return tr = repo.currenttransaction() if tr: tr.addfilegenerator('dirstate', (self._filename,), self._writedirstate, location='plain') return # omit actual writing out st = self._opener('dirstate', "w", atomictemp=True) self._writedirstate(st) This patch makes '_savebackup()' write in-memory changes out, and it causes clearing 'self._dirty'. If dirstate isn't changed after '_savebackup()', subsequent 'dirstate.write()' never invokes 'tr.addfilegenerator()' because 'not self._dirty' is true. Then, 'tr.writepending()' unintentionally returns False, if there is no other (e.g. changelog) changes pending, even though dirstate changes are already written out at '_savebackup()'. To avoid such situation, this patch makes '_savebackup()' explicitly invoke 'tr.addfilegenerator()', if transaction is running. '_savebackup()' should get awareness of transaction before 'write()', because the former depends on the behavior of the latter before this patch.
