memory-usage: fix `hg log --follow --rev R F` space complexity When running `hg log --follow --rev REVS FILES`, the log code will walk the history of all FILES starting from the file revisions that exists in each REVS. Before doing so, it looks if the files actually exists in the target revisions. To do so, it opens the manifest of each revision in REVS to look up if we find the associated items in FILES. Before this changeset this was done in a way that created a changectx for each target revision, keeping them in memory while we look into each file. If the set of REVS is large, this means keeping the manifest for each entry in REVS in memory. That can be large… if REV is in the form `::X`, this can quickly become huge and saturate the memory. We have seen usage allocating 2GB per second until memory runs out. So this changeset invert the two loop so that only one revision is kept in memory during the operation. This solve the memory explosion issue.

tests: run many tests in $TESTTMP/repo instead of $TESTTMP This is useful so we can store other files in $TESTTMP (in particular tests that use docket files (nodemap, dirstate-v2) keep file uids in $TESTTMP/UID)

tests: fix the detection of dirstate-v2 in hghave.py

dirstate-v2: do not put the dirstate data file in a transaction, since the transaction reverts the store, while the dirstate is stored separately

commit: properly consider file include and exclude options when closing branch It looks like this is meant to prevent adding another commit that does nothing but close a branch on top of a commit that already closed the branch. The matcher building functions want `Dict[bytes, Any]`, not `Dict[str, Any]`, which was found by adding type hints to the matcher related methods in scmutil.

tests: demonstrate a bug blocking a redundant branch close

tests: stop creating temporary files in TESTDIR

cffi: fix a bytes vs str issue on macOS when listing directories This code hasn't been touched in recent years, and the other implementation return bytes for the filename, so I assume this is a holdover from the py2 days. I was unable to test it on mac though, because the `_osutil` import failed.

packaging: refresh dependency hashes (issue6750) Also, add some documentation to the `.in` files.

matcher: do not prepend '.*' to pattern using ^ after flags Since the previous commit (fixing wider issue), the code generated strange regex. This is now fixed and tested.

matcher: fix the issue with regex inline-flag in rust oo Same problem same solution.

matcher: fix issues regex flag contained in pattern (issue6759) Python 3.11 is now enforcing that flag must be at the beginning of the regex This creates a serious regression for people using Python 3.11 with an hgignore using flag in a "relre" pattern. We now detect any flags in such pattern and "prepend" our ".*" pattern after them. In addition, we now insert the flag in the regexp to only affect the pattern we are rewriting. Otherwise, the regex built from the combined pattern would these flags in the middle of it anyway. As a side effect of this last change, we fix a bug… before this change regex flag in a pattern would affect all combined patterns. That was bad and is not longer the case. The Rust code needs to be updated to fix that very bug, but we will do it in another changeset.

release: removed the 6.3.0 tag The revision having two tags confuses some of the build script trying to fetch the version. So, remove the "bad" tag for now.

hg-core: relax dependencies pinning Being this rigid makes packagers' job more difficult since they might not carry the exact version. This hard pinning was introduced in eb02decdf but wasn't strictly necessary to achieve its compatibility goal.

tests: make running ls in a no longer existing directory more portable On Linux, ls -A simply returns nothing and the exit code is 0. On NetBSD, ls -A complains that . doesn't exist and the exit code is 1. Sadly, it's not possible to do something like "[1] (?)", so " || true" is the best I could come up with.

tests: move some lines inside #if windows-#else block test-removeemptydirs.t This is done to make it's clear that windows is not affected by this test case, IOW windows and non-windows platforms are now tested separately, because their results are very different.
