mergestate: define NO_OP_ACTION in module scope instead of inside mergeresult This makes sure it isn't intended to be overridden by subclasses. Thanks to Yuya for the nice suggestion. Differential Revision: https://phab.mercurial-scm.org/D9025

mergestate: introduce a new ACTION_KEEP_NEW `ACTION_KEEP` is overloaded and it's hard to figure out how we end up with this KEEP, what was the state of things. In a previous patch, we introduced `ACTION_KEEP_ABSENT` which represents files which are kept absent in the working directory. There is another special case where we keep the file when it's not present on both ancestor and remote side. We introduce a dedicated action for that. The goal is to use these information to make bid merge smarter. Differential Revision: https://phab.mercurial-scm.org/D9002

repoview: don't crash if mergestate points to non-existent node Differential Revision: https://phab.mercurial-scm.org/D9078

tests: demonstrate crash caused by pinning of non-existent mergestate node If the mergestate somehow contains a reference to a non-existent node, it causes most commands to crash since aaeccdb6e654 (repoview: pin revisions for `local` and `other` when a merge is active, 2020-09-04). This patch adds a test showing that. Differential Revision: https://phab.mercurial-scm.org/D9077

git: also convert timezone to int (issue6359) Credit to moshez for testing this in the wild. Differential Revision: https://phab.mercurial-scm.org/D9062

chg: fallback to original hg if stdio fds are missing If stdio fds are missing (ex. fd 0 is not present), chg might open fds that take the numbers 0, and attachio would send the wrong fds to the client, which might cause unwanted behaviors. Avoid that by detecting the missing fds and falling back to the original hg. Differential Revision: https://phab.mercurial-scm.org/D9058

locking: remove support for inheriting locks in subprocess This seems to have been added for merge driver, and since merge driver is now gone... Differential Revision: https://phab.mercurial-scm.org/D9053

mergedriver: delete it The merge driver code was added in late 2015. I think '406a654b::6f045b56 & user("sid0")' is a reasonable revset for finding the relevant commits, including preparation for it. The code is very poorly tested, which makes it very hard to maintain. It seems it's only used by FB and they don't use this code base anymore, so let's remove the code to make it easier for us to maintain our product.

rust-cpython: switch logging facade from `simple_logger` to `env_logger` `simple_logger` is just too simple. `env_logger` supports logging to `stderr`, and logging filtering, for example, which are becoming necessary now. The project is nicely active. Differential Revision: https://phab.mercurial-scm.org/D8990

git: pass `id` attribute of `pygit2.Tree` object `pygit2`'s Repository object expects an instance of `Oid` to return the corresponding object, instead of the object itself. After this change and D9062, `hg commit -i` seems to work, unless it hits a case folding assertion (ie trying to add a file like `README.md`). Differential Revision: https://phab.mercurial-scm.org/D9068

branchmap: add a cache validation cache, avoid expensive re-hash on every use In a pathological `hg log` case, we end up executing the branchmap validity checking twice per commit displayed. Or maybe we always do, and I just noticed because it's really slow in this repo for some reason.

merge with stable

run-test: allow relative path in `--blacklist` and `--whitelist` (issue6351) When specifying a test with `--blacklist` or `--whitelist` with path relatives to the repository root (eg: `tests/test-check-commit.t`) the file is not taken into account. It only works when the name of the test is given. It would be better if `--blacklist` and `--whitelist` behaviors where compatible with `--test-list`. This patch allows to use relative path with `--blacklist` and `--whitelist` while staying compatible with the old behavior by checking the test relative path in addition to its name.

rebase: stop clearing on-disk mergestate when running in memory In-memory merge no longer uses on-disk mergestate since 19590b126764 (merge: use in-memory mergestate when using in-memory context, 2020-09-15). This patch removes the clearing from two places in the in-memory rebase code. I've verified that the one with a TODO was indeed fixed by the aforementioned commit. The other instance doesn't seem to have any test coverage, but I'm pretty confident it's also safe to remove. Differential Revision: https://phab.mercurial-scm.org/D9057

rebase: delete unused p1 argument to _concludenode() Unused since a0192a03216d (rebase: remove now unnecessary logic to allow empty commit when branch changes, 2020-07-09). Differential Revision: https://phab.mercurial-scm.org/D9055

rebase: fix an inconsistent hyphenation in a debug message We used "rebasing on disk" but "rebasing in-memory". I believe the former is correct, so I used that. Differential Revision: https://phab.mercurial-scm.org/D9054
