lfs: add a progress bar when searching for blobs to upload The search itself can take an extreme amount of time if there are a lot of revisions involved. I've got a local repo that took 6 minutes to push 1850 commits, and 60% of that time was spent here (there are ~70K files): \ 58.1% wrapper.py: extractpointers line 297: pointers = extractpointers(... | 57.7% wrapper.py: pointersfromctx line 352: for p in pointersfromctx(ct... | 57.4% wrapper.py: pointerfromctx line 397: p = pointerfromctx(ctx, f, ... \ 38.7% context.py: __contains__ line 368: if f not in ctx: | 38.7% util.py: __get__ line 82: return key in self._manifest | 38.7% context.py: _manifest line 1416: result = self.func(obj) | 38.7% manifest.py: read line 472: return self._manifestctx.re... \ 25.6% revlog.py: revision line 1562: text = rl.revision(self._node) \ 12.8% revlog.py: _chunks line 2217: bins = self._chunks(chain, ... | 12.0% revlog.py: decompressline 2112: ladd(decomp(buffer(data, ch... \ 7.8% revlog.py: checkhash line 2232: self.checkhash(text, node, ... | 7.8% revlog.py: hash line 2315: if node != self.hash(text, ... | 7.8% revlog.py: hash line 2242: return hash(text, p1, p2) \ 12.0% manifest.py: __init__ line 1565: self._data = manifestdict(t... \ 16.8% context.py: filenode line 378: if not _islfs(fctx.filelog(... | 15.7% util.py: __get__ line 706: return self._filelog | 14.8% context.py: _filelog line 1416: result = self.func(obj) | 14.8% localrepo.py: file line 629: return self._repo.file(self... | 14.8% filelog.py: __init__ line 1134: return filelog.filelog(self... | 14.5% revlog.py: __init__ line 24: censorable=True)

# dirstatenonnormalcheck.py - extension to check the consistency of the
# dirstate's non-normal map
#
# For most operations on dirstate, this extensions checks that the nonnormalset
# contains the right entries.
# It compares the nonnormal file to a nonnormalset built from the map of all
# the files in the dirstate to check that they contain the same files.
