commit: fix a wrong argument name in documentation Differential Revision: https://phab.mercurial-scm.org/D8985

git: remove unrequired assignment of listignored and listunknown Caught by test-check-pyflakes.t

grep: fix hash(linestate) to not include linenum linestate.__eq__() just compares the line values whereas __hash__() does hash both self.line and self.linenum, which violates the rule. __hash__() was added at fb502719c75c, "python 2.6 compatibility: add __hash__ to classes that have __eq__" with no additional remarks, so this would probably be a simple mistake. The test output changed because difflib.SequenceMatcher() internally uses a dict. As you can see, the line "export" is unchanged at the revision 2, so the new output is correct.

test-grep: document that trivially moved lines might not be detected I'm not going to fix this. I just learned "grep --diff" does clever thing than a simple grep(patch.diff(context=0)), and I think it's better to document how things work.

revset: remove indirect indexing of status tuple Just use the attribute name.

rewriteutil: relax the sha1 hash references to handle future hash types Per discussion with nbjoerg in IRC. Differential Revision: https://phab.mercurial-scm.org/D8951

phabricator: update the hashes in commit messages as they get submitted Due to the sequence of actions (posting, amending the local commit, and then updating the Differential properties), the message in the commit is updated on the initial send but the message displayed in Phabricator is not. It should get updated there if the review is reposted. The data in the Commits tab is accurate for the first `phabsend`. Differential Revision: https://phab.mercurial-scm.org/D8950

rewriteutil: also consider pending obsoletes when updating hashes in messages Phabricator builds up the replacement commits and mapping in a single transaction, and then finalizes everything once the commits have been rewritten. That's too late when trying to update the messages for those commits. I'm a little concerned that this isn't a generic enough interface, since it doesn't mimic the list of list return of `obsutil.successorssets()`. But this is the type of mapping that phabricator maintains, and I don't think the methods that would be interested in calling this need to worry about split and divergence. We can fix that later if the need arises. Differential Revision: https://phab.mercurial-scm.org/D8949

rewriteutil: extract evolve code used to replace obsolete hashes in commits The evolve command uses it, but there are core things like `phabsend` and `rebase` that would also benefit. Differential Revision: https://phab.mercurial-scm.org/D8948

git: fix index handling of removed files during commit (issue6398) Other changes in this series also changed the behavior here in positive ways, but this was the final step that actually fixed things. Differential Revision: https://phab.mercurial-scm.org/D8999

git: make dirstate actually support listclean parameter As far as I can tell listignored and listunknown should already work. I'm vexed that there doesn't seem to be a way to get clean files out of the pygit2 status method, but this at least makes things work better. Differential Revision: https://phab.mercurial-scm.org/D8998

git: make dirstate status() respect matcher As with other changes in this stack, we appear to have been getting lucky in the past. An upcoming change behaved _very_ oddly without this fix. Differential Revision: https://phab.mercurial-scm.org/D8997

git: fix up dirstate use of index This was super-broken before, and somehow none of the existing attempts to use this code tripped on the defects here. Sigh. Differential Revision: https://phab.mercurial-scm.org/D8996

git: correctly handle "nothing changed" commits I guess localrepo.commit() actually returns an Optional[node], which is a bit of a surprise to me. Differential Revision: https://phab.mercurial-scm.org/D8995

localrepo: use functools.wraps() in unfilteredmethod decorator This makes it easier to figure out what function you're holding on to when doing printf-style debugging. Differential Revision: https://phab.mercurial-scm.org/D8994

git: actually copy treemanifest instances in .copy() (issue6398) The implementation here is so simple I honestly have no idea why I didn't do it at the time. Hopefully there's not some nuance past-me forgot to write down. Differential Revision: https://phab.mercurial-scm.org/D8993

log: fix crash and bad filematcher lookup by -fr'wdir()' PATH "-fr'wdir()' ADDED-PATH" is still wrong, which will be fixed in default branch.

hgdemandimport: bypass demandimport for _ast module (issue6407) This is broken on Python 3.9rc1, and while it sounds like there may be a fix in Python, we probably also should have this workaround in place in hg. See the bug for more details (including on bugs at redhat and b.p.o). Differential Revision: https://phab.mercurial-scm.org/D9004

git: restore basic functionality after b3040b6739ce We don't yet have a formal interface for the changelog, but it's mostly specified. Sadly, b3040b6739ce added a semi-private pseudo-enum that we need to cope with, so it's probably high time that someone (me?) attempts to define that interface to prevent future backsliding.

git: convert tz offset to int (issue6359) Differential Revision: https://phab.mercurial-scm.org/D8991

repoview: pin revisions for `local` and `other` when a merge is active I've hit this a couple of times, where pulling with a dirty `wdir` obsoletes `p1` and updating to the successor results in merge conflicts. The problem was resolving them failed immediately, complaining that the old checkout was filtered. The change in `test-rebase-obsolete.t` is because there's an outstanding merge conflict in a rebase operation. The summary prompt to merge seems incorrect for this scenario, but that's an existing issue. Differential Revision: https://phab.mercurial-scm.org/D8980

merge with stable

extdiff: refactor cmdline and gui calculation login in a separate fn This is some good logic with handling of many config items and various ways of specifying it. I want to reuse in `diff --tool` and hence refatcored it in a separate function of it's own.

extdiff: reorder an if-else conditional This brings continue part on top and will help in next patch where we will like to introduce utility functions for rest of the code.

run-tests: extract logic to get errpath in a utility func Differential Revision: https://phab.mercurial-scm.org/D8979

run-tests: refactor filtering logic for --retest flag How I got to this: While re-running failed tests using --retest I noticed that the output: "running x tests using y parallel processes". was not actually correct, because x was the total number of tests present in the directory, but it should be the number of failed tests. Although it would run only the failed tests and later will say that remaining tests were skipped. Changes in test files reflect the fixed behaviour. This patch change and move the logic for filtering failed test for --retest option and make sure that we create instances of class Test only for the tests we need to run. As mentioned in the deleted text (in this patch itself) the logic for --retest should be outside of TestSuite. Differential Revision: https://phab.mercurial-scm.org/D8938

tests: add a --retest test to demonstrate a fix in next patch As you see above the added lines, there was only one test failed. So the output should be: "running 1 tests using 1 parallel processes" Next patch will be fixing this. Differential Revision: https://phab.mercurial-scm.org/D8964

tests: remove a sub-test since we are done with it in test-run-tests.t removing test-failure.t to make sure that in next patch when we re-run failed tests using --retest, it won't get considered unnecessarily. Differential Revision: https://phab.mercurial-scm.org/D8963
