templatefuncs: minimize resource requirements

split: preserve phase of commit that is being split With this change, hg split will preserve the phase of the commit that is being split, ignoring the phases.new-commit setting. Previously, we would use whatever phases.new-commit was set to (unless our parent was secret, then we would be secret even if phases.new-commit=draft). Now, splitting a draft commit with phases.new-commit=secret does not cause the new commits to become secret, and splitting a secret commit with phases.new-commit=draft and a draft parent does not cause the new commits to become draft. Test cases and commit message taken from Kyle Lippincott's D2016 (thanks!). Differential Revision: https://phab.mercurial-scm.org/D3819

scmutil: make cleanupnodes optionally also fix the phase We have had multiple bugs where the phase wasn't correctly carried forward to a rewritten changeset (for example: phabricator, split, evolve, fix). Handling the phase update in cleanupnodes() makes it less likely to happen again, especially once we have made it fix the phase by default (perhaps in the next release cycle). This patch also updates all applicable callers so we get some testing of it. Note that rebase and histedit can't be fixed yet because they call cleanupnodes() only at the end and the phase may have been changed by the user when the rebase/histedit was interrupted (due to merge conflicts). I think we should make them write one commit at a time (as it already does), along with associated obsmarkers, bookmark moves, etc. When that's done, we can switch them over to cleanupnodes().

tests: add test of uncommit with default phase as secret We didn't seem to have any test checking that uncommitting a draft commit with phase.new-phase=secret preserved the draft phase. Differential Revision: https://phab.mercurial-scm.org/D3817

grep: add --diff flag Adds a diff flag, which works exactly same as all, in fact since --all searches diffs, there diff is a better name for it. The all flag is still here for backward compatibility reasons. Some major tests for all has been picked and added for diff. Differential Revision: https://phab.mercurial-scm.org/D3763

fix: include cleanupnodes() in transaction As pointed out by Yuya, we need a transaction to make sure the state before the call to cleanupnodes() is not observable. Differential Revision: https://phab.mercurial-scm.org/D3823

progress: enforce use of complete() on the helper class complete() is preferred over update(None), so let's enforce that. Differential Revision: https://phab.mercurial-scm.org/D3822

progress: extract function for closing topic progress(None) had a completely different implementation from the progress(<not None>) implementation. It very much feels like it should be a separate method, so this patch makes it so. That also makes it clear that only the topic parameter matters when closing a topic (e.g. "total" does not matter).

progress: use context manager for lock Differential Revision: https://phab.mercurial-scm.org/D3820

configitem: reorder items in the 'server' section Keeping things alphabetically sorted.

test-lfs: add coverage for the binary() fileset This ensures that the blobs don't need to be present to be filtered properly.

fileset: use filectx.isbinary() to filter out binaries in eol() Since LFS stores the binary attribute in the pointer file, this means that the file doesn't need to be downloaded in order to be skipped. This function also catches an IOError if the data can't be loaded in the non-LFS case. I wonder if it's worth storing the unix/dos attributes in the pointer file as well, though I'd expect LFS files to be binary most of the time.

crecord: re-center display in interactive curses commit on pageup/down A long-standing issue in the crecord (interactive curses commit interface) is that using PageUp/Down to move along longer-than current screen size chunks would "lose" the cursor and not properly re-center. There has been self.recenterdisplayedarea() to do that, but it has not been in use for some reason. Add calls to the appropriate uparrowshiftevent() and downarrowshiftevent() methods to fix this.
