logtoprocess: update commandfinish options arguments d2c997b8001f changed the logtoprocess API with the effect of not exposing the positional arguments to the logtoprocess scripts anymore. We have some scripts that use the duration and return code of the "commandfinish" event to monitor hg calls. Update the logging of the "commandfinish" to expose those values as options argument, which will be accessible as `OPT_RETURN_CODE` and `OPT_DURATION` in logtoprocess arguments. The code has been formatted with Black. Differential Revision: https://phab.mercurial-scm.org/D5282

rebase: fix two ui.logs to actually have text when using default blackbox log Some implementations of ui.log record structured information along with the ui.log which can be used for metrics, but ui.log() as implemented by the blackbox logging does not do anything special with this, and we end up with a log line with no text (not even a line break) so it ends up looking something like: date time user @node (pid) [rebase]> date time user @node (pid) ...

wireprotov2server: let repo.narrowmatch(match) do matcher intersection This is supported since 4fd0fac48922 (localrepo: allow narrowmatch() to accept matcher to intersect with, 2018-09-28). Differential Revision: https://phab.mercurial-scm.org/D5281

blackbox: extract function to test if log event is tracked This will be a required method of the logger interface.

blackbox: initialize inlog flag properly And ditch the "bb" prefix as it's no longer a ui extension class.

blackbox: initialize repo attribute properly And ditch the "bb" prefix as it's no longer a ui extension class.

blackbox: unindent "if True" block

blackbox: extract logger class from ui wrapper This moves most functions to new blackboxlogger class. The ui wrapper will be removed later.

blackbox: rename variables to prepare extracting core logic from ui wrapper I'm going to add ui.setlogger() function so that I can enable logging feature in command server without extending ui.__class__. This prepares for it. "self" will be a logger instance, so this patch renames some of them to "ui".

sparse-revlog: rework the way we enforce chunk size limit We move from a O(N) algorithm to a O(log(N)) algorithm. The previous algorithm was traversing the whole delta chain, looking for the exact point where it became too big. This would result in most of the delta chain to be traversed. Instead, we now use a "binary" approach, slicing the chain in two until we have a chunk of the appropriate size. We still keep the previous algorithm for the snapshots part. There are few of them and they are large bits of data distant from each other. So the previous algorithm should work well in that case. To take a practical example of restoring manifest revision '59547c40bc4c' for a reference NetBeans repository (using sparse-revlog). The media time of the step `slice-sparse-chain` of `perfrevlogrevision` improve from 1.109 ms to 0.660 ms.

doctest: add a `issnapshot` method to _testrevlog We'll need it soon.

tests: add `revlogutils.deltas` module to doctests The doctest in these module have been from `mercurial.revlog` but the module was not added to the doctests. Spotted by Yuya Nishihara.

mergetools: adjust Beyond Compare config on Mac/Linux Set the labels of the Linux and Mac versions of Beyond Compare from Mercurial's builtin variables, same as the Windows version. Differential Revision: https://phab.mercurial-scm.org/D5255

tests: allow for 100% of profiled time in sleep in test-profile.t I'm getting an annoying failure in this test on our builder, and I *think* what's happening is that the profiler is taking _just_ long enough to start that we're spending 100% of the profiled time in the sleep function, which was causing the leading space to not be printed since the 100 was in the first column of output.
