remotefilelog: add missing argument to hg.verify wrapper Differential Revision: https://phab.mercurial-scm.org/D6313

revsetbenchmark: track some simple use of "only" The only revset is quite useful and has various possible optimisation. tracking its timing seems useful.

push: added clear warning message when pushing closed branches(issue6080) Differential Revision: https://phab.mercurial-scm.org/D6038

branch: abort if closing branch from a non-branchhead cset This patch make sure that we abort if the user is trying to close a branch from a cset which is not a branch head. Changes in test file reflect the fixed behaviour. Differential Revision: https://phab.mercurial-scm.org/D6282

branch: add tests which shows branch can be closed from a non-branchhead cset This patch shows that we can close a branch even from a cset which is not a branch head. It was supposed to abort this operation. Next patch will be fixing the issue. Differential Revision: https://phab.mercurial-scm.org/D6281

phabricator: read more metadata from local:commits local:commits metadata can contain branch info, and 'rev' has been superseded by 'commit', see: https://github.com/phacility/arcanist/blob/83661809e532c3fe444a8bf7c7d6936e6377691b/src/repository/api/ArcanistMercurialAPI.php#L281 Differential Revision: https://phab.mercurial-scm.org/D6300

phabricator: don't assume the existence of properties of local:commits Not all the properties are guaranteed to be there, so if we don't check first we could die with a KeyError. Differential Revision: https://phab.mercurial-scm.org/D6299

phabricator: include branch in the diffproperty metadata This does not make Phabricator display the branch in web UI anywhere as that still need us to use creatediff API for that. However a future patch will make phabread use this to include the branch in its `hg import`-able output. Differential Revision: https://phab.mercurial-scm.org/D6297

fix: allow fixer tools to return metadata in addition to the file content With this change, fixer tools can be configured to output a JSON object that will be parsed and passed to hooks that can be used to print summaries of what code was formatted or perform other post-fixing work. The motivation for this change is to allow parallel executions of a "meta-formatter" tool to report back statistics, which are then aggregated and processed after all formatting has completed. Providing an extensible mechanism inside fix.py is far simpler, and more portable, than trying to make a tool like this communicate through some other channel.

phabricator: set local:commits time metadata as an int, not a string Same as arcanist does Differential Revision: https://phab.mercurial-scm.org/D6296

phabricator: use templatefilters.json in writediffproperties Instead of json.dumps, since it makes the code simpler and more readable. This would have been the better option for 8fd19a7b4ed6 but I wasn't aware of it at the time. Differential Revision: https://phab.mercurial-scm.org/D6295

commands: use byteskwargs() in verify() Otherwise Python 3 complains about the missing key. Differential Revision: https://phab.mercurial-scm.org/D6294

match: use raw strings to avoid illegal baskslash escape Python 3.8 was complaining about the invalid escape sequences. Let's use raw strings to avoid the warning and double baskslashes. Differential Revision: https://phab.mercurial-scm.org/D6293

revbranchcache: use context manager in _writerevs() to write to file The other _writenames() is a bit complicated to use context manager. Differential Revision: https://phab.mercurial-scm.org/D6292

revbranchcache: factor logic to write names and revs in separate functions Before this patch, the write function was so populated with upto 4 level of indentation, it was hard to understand what's going on. Differential Revision: https://phab.mercurial-scm.org/D6291

tests: make log style a little easier to read in test-copytrace-heuristics.t Revision numbers are much shorter and easier to read (especially compared to the full nodeids that were used here), so I switched to that. That's also what almost all the commands used (e.g. `hg rebase -s . -d 1`). I updated the two instances that used nodeids. I also made some other little cleanups to the log templates. Differential Revision: https://phab.mercurial-scm.org/D6279

tests: avoid cryptic nodeids in tests/test-rename-merge1.t These two nodeids had not been part of any output before, so one can't know which revision they refer to without adding something like `hg log` before them. It turned out that '.^' was equivalent for both of them, so that's what I replaced them with. Differential Revision: https://phab.mercurial-scm.org/D6280

tests: defines aliases for `hg log` calls in test-copytrace-heuristics.t This also makes the test cases more consistent since a few had missed the ":" in "changeset:" that the others used. Differential Revision: https://phab.mercurial-scm.org/D6278
