rebase: adds storing collapse message (issue4792) Before this patch collapse message wasn't stored so when you ran into the merge conflict while rebasing, running rebase --continue didn't remember the message and always opened editor to fill commit message. This patch adds saving collapse message in .hg/last-message.txt and restoring it later when needed.

test-automv: fix inline config settings for 5ec1ce8fdf0a

automv: use 95 as the default similarity threshold The motivation for the change from 100 to 95 is included in a comment. * Updated the tests to include a change to a moved file that still should be caught as a move. * Use ui.configint() to non-integer configuration entries more gracefully. Also complain if a similarity outside of the acceptable range is set.

bookmarks: add 'hg push -B .' for pushing the active bookmark (issue4917)

worker: change partition strategy to every Nth element The only consumer of the worker pool code today is `hg update`. Previously, the algorithm to partition work to each worker process preserved input list ordering. We'd take the first N elements, then the next N elements, etc. Measurements on mozilla-central demonstrate this isn't an optimal partitioning strategy. I added debug code to print when workers were exiting. When performing a working copy update on a previously empty working copy of mozilla-central, I noticed that process lifetimes were all over the map. One worker would complete after 7s. Many would complete after 12s. And another worker would often take >16s. This behavior occurred for many worker process counts and was more pronounced on some than others. What I suspect is happening is some workers end up with lots of small files and others with large files. This is because the update code passes in actions according to sorted filenames. And, directories under tend to accumulate similar files. For example, test directories often consist of many small test files and media directories contain binary (often larger) media files. This patch changes the partitioning algorithm to select every Nth element from the input list. Each worker thus has a similar composition of files to operate on. The result of this change is that worker processes now all tend to exit around the same time. The possibility of a long pole due to being unlucky and receiving all the large files has been mitigated. Overall execution time seems to drop, but not by a statistically significant amount on mozilla-central. However, repositories with directories containing many large files will likely show a drop. There shouldn't be any regressions due to partial manifest decoding because the update code already iterates the manifest to determine what files to operate on, so the manifest should already be decoded.

run-tests: allow run-tests.py to run tests outside current directory When reloading tests, run-tests.py was assuming that it could look up the test by the basename, which only works if you are running tests which are in the current directory. This patch changes that lookup to use the full path. This is all that was needed, and does not appear to cause any problems for any of the existing testing work flows based on running the suggested commands at the top of run-tests.py. Motivation: In order to test Mercurial with Hypothesis (according to https://www.mercurial-scm.org/wiki/HypothesisPlan) it is useful to be able to generate temporary test files and execute them. Generating temporary files in the tests/ directory leads to a lot of suboptimal clutter.

histedit: unifying the way replacements are computed for abort and success This is a part of a bigger refactoring effort with the ultimate goal of better understanding of how histedit works and fixing issue4800.

templater: factor out type conversion of revset() result This makes it clear why we have to do repo[int(x)].

templater: evaluate each item of revset() as integer revision Because templater.revset() returns a list of strings, repo["-1"] was mapped to the tipmost revision. Ideally, we should make revset() return a list of integer revisions, but it turned out not simple. If revset() is a list of integers, "{ifcontains(rev, revset(), ...)}" would fail because "ifcontains" casts "rev" to a string. So this patch just converts a string back to an integer revision.

demandimport: blacklist sqlalchemy.events as it has side effects (issue5085) Importing sqlalchemy.events cannot be delayed as it registers classes to their event mechanism. It worked fine before 4f1144c3c72b, since they use new-style imports. But now we have to blacklist it because our demandimport can handle new-style imports. This patch series isn't intended for stable as we don't guarantee API compatibility with 3rd-party extensions. They can temporarily disable the demand importer to work around the issue.
