windows: gracefully handle when the username cannot be determined This assumes implementation details, but I don't see any other way than to check the environment variables ourselves (which would miss out on any future enhancements that Python may make). This was originally reported as https://foss.heptapod.net/mercurial/tortoisehg/thg/-/issues/5835.

shelve: do not add the dirstate backup to the transaction Otherwise the transaction will properly clean up its mess on abort… deleting the backup in the process. This break with dirstate-v2 that has more file than just the dirstate. The dirstate itself is full of various exception and is "fine" when using dirstate-v1.

heptapod-ci: use shell script in pytype step

tests: migrate the pytype test to a shell script for easier CI processing There have been recent hangs and timeout, but it's hard to debug because the *.t test redirects output to a file and only prints it if `pytype` actually exits. This shell script can be run directly by CI, and will allow more flexibility to try to cache and restore type stubs for further speed increases.

rhg: fix bugs around [use-dirstate-tracked-hint] and repo auto-upgrade This makes two changes: - make rhg support the [dirstate-tracked-key-v1] requirement. I believe rhg never changes the tracked file set, so it's OK that it doesn't have any logic for writing this file. - fix the name of [format.use-dirstate-v2.automatic-upgrade-of-mismatching-repositories] config option in rhg, which makes rhg actually honor the auto-upgrade. These two issues cancelled each other out in tests (auto-upgrade was happening because [dirstate-tracked-key-v1] forced the fallback, not because of the config), which is I think why they went unnoticed earlier.

tests: fix the flaky test test-logtoprocess.t The main change is that we're waiting for the [touched] file to appear for 5 seconds instead of 0.1 seconds. Also, instead of implementing wait-on-file from scratch, we use the existing one from testlib/ that works well.

packaging: update dulwich to drop the certifi dependency on Windows The presence of `certifi` causes the system certificate store to be ignored, which was reported as a bug against TortoiseHg[1]. It was only pulled in on Windows because of `dulwich`, which was copied from the old TortoiseHg install scripts, in order to support `hg-git`. This version of `dulwich` raises the minimum `urllib3` to a version (1.25) that does certificate verification by default, without the help of `certifi`[2]. We already bundle a newer version of `urllib3`. Note that `certifi` can still be imported from the user site directory, if installed there. But the installer no longer disables the system certificates by default. [1] https://foss.heptapod.net/mercurial/tortoisehg/thg/-/issues/5825 [2] https://github.com/jelmer/dulwich/issues/1025

dirstate-v2: no longer register the data-file during transaction If the data file change during the transaction, we cannot truncate it. The content of the file itself is fine as it will get backed up at the same time as the docket. Leaving the trailing data at the end of failed transaction is fine. The dirstate-v2 format supports it. The dead data will simply we written over if necessary.

fsmonitor: use new dirstate APIs (issue6728) On top of fixing fsmonitor, it moves one more "old API" use to the new one. This needs very verbose code to save a few function calls that are very expensive in Python.
