tests: apply binary mode to output in seq.py I noticed this when playing with running tests using WSL, and iterating over the output yielded '0\r', '1\r',... Most of the other *.py tools do this, and `seq` on MSYS lacks '\r' in the output, so this is more consistent.

perf: add a `--clear-caches` to `perfbranchmapupdate` This flag will help to measure the time we spend loading various cache that support the branchmap update. Example for an 500 000 revisions repository: hg perfbranchmapupdate --base 'not tip' --target 'tip' ! wall 0.000860 comb 0.000000 user 0.000000 sys 0.000000 (best of 336) hg perfbranchmapupdate --base 'not tip' --target 'tip' --clear-caches ! wall 0.029494 comb 0.030000 user 0.030000 sys 0.000000 (best of 100)

perf: start from an existing branchmap if possible If the --base set if a superset of one of the cached branchmap, we should use as a starting point. This greatly help the overall runtime of `hg perfbranchmapupdate` For example, for a repository with about 500 000 revisions, using this trick make the command runtime move from about 200 second to about 10 seconds. A 20x gain.

perf: rely on repoview for perfbranchmapupdate Using 'repoview' matching the base and target subset make the benchmark more realistic. It also unlocks optimization to make the command initialization faster.

perf: pre-indent some code in `perfbranchmapupdate` This make the next patch easier to read.

perf: add a `perfbranchmapupdate` command This command benchmark the time necessary to update the branchmap between two sets of revisions. This changeset introduce a first version, doing nothing fancy regarding cache or other internal details.

push: config option to control behavior when pushing to a publishing server Pushing to a publishing server by mistake can lead to a difficult situation to solve because evolution doesn't work on public changesets. This new experimental config tries to help avoiding unintentionally (or at least being aware of) pushing to publishing remotes. `hg push --publish` can be used to make push succeed even when auto-publish is set to 'abort'.

narrowcommands: remove an unrequired `repo.narrowpats` call We call that few lines above and do nothing significant in between which can change the narrowpats. So let's use values returned by that call. Differential Revision: https://phab.mercurial-scm.org/D5348

manifest: reject lines shorter than 42 bytes, not 22 Yuya correctly spotted during the review of f27f8e9ef1e73 that we're dealing with hexlified hashes here, and so it should be 42 bytes not 22. Differential Revision: https://phab.mercurial-scm.org/D5347

blackbox: initialize logger with repo instance The blackboxlogger is unusable without a repo. Let's simply initialize it with a repo instance.
