largefiles: factor out procedures to update standins for pre-committing...

largefiles: factor out procedures to update standins for pre-committing This patch factors out procedures to update standins for pre-committing. This is one of preparations to avoid execution of such procedures according to invocation context. For example, resuming automated committing (e.g. "hg rebase --continue") should update standins at the 1st commit, because largefiles in the working directory may be modified manually. But on the other hand, it should avoid updating standins at subsequent committings for efficiency reason. For simplicity, this patch just moves procedures mechanically only with replacing below. - "self" => "repo" - "lfutil." => (none) - "orig" invocation => returning "match" Using "fstandin" instead "standin" as the name of local variable for the loop below is the only special care, because the latter shadows the same name function in "lfutil.py". [before] for standin in standins: lfile = lfutil.splitstandin(standin) if lfdirstate[lfile] != 'r': lfutil.updatestandin(self, standin) [after] for fstandin in standins: lfile = splitstandin(fstandin) if lfdirstate[lfile] != 'r': updatestandin(repo, fstandin)

      Setup:

      create a little extension that has 3 side-effects:

      1) ensure changelog data is not inlined

      2) make revlog to use lazyparser

      3) test that repo.lookup() works

      1 and 2 are preconditions for the bug; 3 is the bug.
