dirstate: make functions for backup aware of transaction activity
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.
