test-transaction-safety: document the test schedule This helps reader to understand how the test work and actually helped me to detect a missing synchronisation step. Differential Revision: https://phab.mercurial-scm.org/D11215

rhg: Propagate permission errors when finding a repository The Rust standard library has a `Path::is_dir` method that returns false for any I/O error (such as a permission error), not just "No such file or directory". Instead add an `is_dir` function that returns false for non-directories and for "No such file or directory" errors, but propagates other I/O errors.

rhg: Add build and config instructions to the README file This adds documentation explaining how to compile, configure, and use rhg as well as how the fallback mechanism works. Differential Revision: https://phab.mercurial-scm.org/D11229

dirstate: use `add` in the deprecation message about `add` The previous message was talking about `remove`. Differential Revision: https://phab.mercurial-scm.org/D11224

run-tests: use a small timeout for chg instance There is case where the test runner fails to clean up the temporary files in that case, spawned chg instance can stay around for 1 hours. Getting them to shut down sooner cannot hurt. (We should also use a more robust approach for this cleanup) Differential Revision: https://phab.mercurial-scm.org/D11227

run-tests: do not inherit file descriptor when running a command This is one of the difference between python2 and python3 and could have been a reason why test hang with python2 + chg. This does not seems to help the hanging issue at all… However, now that this is written lets reduce the difference between python2 and python3.

dummyssh: make sure we don't inherit files descriptor to the children This is one of the difference between python2 and python3 and could have been a reason why test hang with python2 + chg. This does not seems to help the hanging issue at all… However, now that this is written lets reduce the difference between python2 and python3.

tests: make test-serve works on system that allow user to bind low port It is possible to encounter linux system configured in a way that allow port < 1024 to be bound by any users. So we update a test to focus more on the actual test: "resolving `daytime` to an actual port number. The new auto-scaling CI runner provided by clever cloud is doing so. This is the initial motivation for this change, but it seems useful anyway. Differential Revision: https://phab.mercurial-scm.org/D11228

git: restore basic functionality (issue6545) It looks like a big refactor happened on dirstate, and the git extension was just ignored. Differential Revision: https://phab.mercurial-scm.org/D11234

dirstate: fix typo in docstring Spotted while repairing git extension tests. Differential Revision: https://phab.mercurial-scm.org/D11233

typing: add several assertions to dirstatemap to appease pytype I think it's been mentioned in IRC that these can't be None in this case. This fixes: File "/mnt/c/Users/Matt/hg/mercurial/dirstatemap.py", line 213, in addfile: unsupported operand type(s) for &: 'None' and 'int' [unsupported-operands] No attribute '__and__' on None or '__rand__' on int Called from (traceback): line 290, in reset_state File "/mnt/c/Users/Matt/hg/mercurial/dirstatemap.py", line 214, in addfile: unsupported operand type(s) for &: 'None' and 'int' [unsupported-operands] No attribute '__and__' on None or '__rand__' on int Called from (traceback): line 290, in reset_state Differential Revision: https://phab.mercurial-scm.org/D11235

help: indicate how to run downgrade a repository using persistent nodemap We have a couple of report of people needing this. I am not fan of pointing people to a debug command, but we don't have much better to offer right now Differential Revision: https://phab.mercurial-scm.org/D11214

fix: use scmutil.movedirstate() instead of reimplementing I wrote this patch 2 years ago as a little cleanup. I wanted to generally used `scmutil.movedirstate()` instead of manually updating the dirstate because that is easy to get wrong. I didn't know until today that the current code had a bug. So I added the test case two patches before this one and dusted off this one patch. This is a little slower than the previous code, as it diffs two manifests. However, it fixes the bug and I don't think it's going to be noticeably slower anyway. Differential Revision: https://phab.mercurial-scm.org/D11210

fix: rewrite writeworkingdir() to explicitly not work with merges `hg fix` errors out early if there is an unfinished merge, so we should have only one parent here. Making that explicit makes my next patches simpler. Differential Revision: https://phab.mercurial-scm.org/D11209

tests: demonstrate bug in `hg fix` with incorrectly dirty working copy If the parent commit needs formatting but the working copy already has the correct formatting, then the working copy will be reported as modified even though it's clean (because the size in the dirstate is incorrect). Because the bug only occurs when the size changes, I modified the formatter used in the test case to remove repeated spaces. Differential Revision: https://phab.mercurial-scm.org/D11208

typing: convert an annotation to an assertion in commands.py Pytype was happy with the annotation at one point, but 2021.04.15 now complains. Differential Revision: https://phab.mercurial-scm.org/D11206

test: remove `sleep` usage in `test-nointerrupt.t` (issue6271) We move from sleep based synchronisation to file creation based synchronisation. Sleeps is the path to the dark side. Sleeps leads to flakiness. Flakiness leads to anger. Anger leads to hate. Hate leads to suffering. Differential Revision: https://phab.mercurial-scm.org/D11205
