obsolete: disable other evolution config options if createmarkers is off We used to raise an abort in this case, but recent changes to local clone command (377d8fc20e34) resulted in destrepo both caring about experimental.evolution config options and not initializing extensions. So imagine if you had evolve and allowdivergence enabled in your ~/.hgrc. Local clone stopped working after 377d8fc20e34 because evolve sets experimental.evolution=all, but only on srcrepo, for destrepo the extension is not initialized. It's possible to make local cloning work by initializing extensions for destrepo in some cases, but in other cases (e.g. allowdivergence in ~/.hgrc, evolve extension in original-repo/.hg/hgrc) it would still fail. In a discussion with Pierre-Yves David it was decided to simply force other evolution options to be false if createmarkers is not enabled.

fix: use obsolete.isenabled() to check for experimental.allowdivergence Now that obsolete.isenabled() can also check if divergence is allowed, let's use it for consistency. Other experimental.evolution options are already checked via this function. Differential Revision: https://phab.mercurial-scm.org/D11222

heptapod-ci: enable pytype testing for all pipelines Now that pytype agrees with the codebase, let's run it by default to catch regressions. Differential Revision: https://phab.mercurial-scm.org/D11242

pytype: add assertions to explain revlogv2 invariants to Pytype Differential Revision: https://phab.mercurial-scm.org/D11241

typing: add several assertions to dirstatemap to appease pytype (grafted from default to stable) 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

windows: avoid a bytes vs unicode crash reading passwords on py2 This broke in 5b3513177f2b. Specifically, after typing in the password on py2, it would crash with: TypeError: putwch() argument 1 must be cannot convert raw buffers, not str

streamclone: ensure the server sends the right amount of data Otherwise, the client would fail with some confusing error. I have seen an error which I think is this, perhaps due to a concurrent revlog split, which streamclones do not handle correctly and would result in a short read of the index of the revlog being split. Differential Revision: https://phab.mercurial-scm.org/D11236

rewriteutil: fix crash when a rewritten message references f{6,64} Without this, the rewriteutil logic thinks it's found a reference to the wdir pseudo-revision, and then tries to look it up and rewrite it. Stop it from doing that. Amusingly, I had trouble working with this changeset when I didn't describe the defect above using a regular expression, because it would trigger the bug in my installed version of hg. Differential Revision: https://phab.mercurial-scm.org/D11232

tests: add explicit coverage for update_hash_refs from rewriteutil I couldn't find any evidence this is covered by tests in core (but there's a good chance I missed it). We've seen a cute bug in that code, but first let's just cover the cases that work correctly. Differential Revision: https://phab.mercurial-scm.org/D11231

test-transaction-safety: relax some of the synchronisation schedule We can have `internal` and `external` runs at the same time, so we unlock `external` a bit sooner. Differential Revision: https://phab.mercurial-scm.org/D11216

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.

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.

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
