registrar: clarify the documentation about some byte strings being required I *thought* these needed to be byte strings, but didn't remember and had to search out examples. Differential Revision: https://phab.mercurial-scm.org/D9489

match: skip walking up the directory hierarchy if the number of pats are small Previously, we would receive a path like abc/def/ghi and "walk up" the directory hierarchy, checking abc/def, abc, and `b''` to see if they were in the set of prefixes that this matcher covered. We did this indiscriminately - we generated all of these paths even if the set of prefixes the matcher covered was completely empty, which is the case for a lot of repos at my company (the narrow matcher we use is usually non-recursive). This brings the time for a rebase in one of my repos from 12.20s to 10.87s. In this particular repo, this is entirely due to the `len(prefix_set) == 0` check, as I do not have any recursive patterns in the narrowspec.

upgrade: add an explicite --filelogs arguments This make it possible to select no revlog for upgrade, which is useful for some upgrade target or in some specific cases (eg: persistent-nodemap or share-safe update). Differential Revision: https://phab.mercurial-scm.org/D9468

rhg: add a test for --rev with a hex changeset ID And fix error message formatting Differential Revision: https://phab.mercurial-scm.org/D9478

upgrade: move optimisation to something more declarative This is not great yet, but still better than the previous state. This get use one step closer to having all the possible "actions" clearly declared and moved in a dedicated module. Differential Revision: https://phab.mercurial-scm.org/D9475

upgrade: capitalize the `deficiency` constant I am reworking this code and moving to the current naming scheme help readability. Differential Revision: https://phab.mercurial-scm.org/D9474

tests: set old git default branch name for compatibility Git's default branch name has changed on my machine (from "master" to "main"). Let's set the old name in our tests so we're compatible with both defaults (and maybe still compatible with Git versions that don't know about the config option).

heptapod-ci: automatically refresh existing phabricator Diff on push If a changeset have been submitted to Phabricator and a new version is pushed to heptapod, we should refresh the state on Phabricator. If we do not do this, they are a risk of an older version being applied from Phabricator. In this situation content-divergence will be (rightfully) detected by evolution. We only refresh the Diff if the test pass, to avoid updating Phabricator with broken content. Differential Revision: https://phab.mercurial-scm.org/D9451

contrib: add a small script to refresh all diff in the current stack This will be useful to introduce automatic refresh through heptapod. Differential Revision: https://phab.mercurial-scm.org/D9460

tests: conditionalize return code on chg in test-config.t If there is any error while reading config, chg just returns 255 instead of 30. It seems to me that we cannot conditionalize only return codes in output using trailing `(chg !)` and hence used testcases. The test was failing with chg but after this patch, it now passes. Differential Revision: https://phab.mercurial-scm.org/D9463

tests: update test-chg.t with output change Since this part of tests is only run with chg, hence it didn't get updated when the error message changed. Differential Revision: https://phab.mercurial-scm.org/D9414

rust-format: pin the formatted to a specific nightly version Version 1.50 change the way rust-format behave. We pin the version for now, we can figure out something better later.

copies: clarify the return of _merge_copies_dict I misused that function twice in the past few days, so lets clarify the API. Differential Revision: https://phab.mercurial-scm.org/D9418
