Added signature for changeset c890d8b8bc59

Added tag 6.3.1 for changeset c890d8b8bc59

relnotes: add 6.3.1

tests: fix test-sparse-revlog This one is not covered by the CIbecause I requires an expensive artifact to be cached. So it goes out of think on regular basis (we should fix that…) The test ouput was affected by e706bb41fdb3 as we filtering now happens sooner, removing for the output.

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

delta-find: adjust the moment when we mark something as "tested" In a coming change, not all elements of `group` might get tested. So we need to have more control about when a revision is actually added to the `tested` set. So we move to a more verbose (and more fragile) version.

delta-find: rename a variable for clarity the index in the delta-chain is also the snapshot depth. So we rename the variable for clarity.

delta-find: small documentation update This is not a 1-1 mapping, but a 1-n mapping. Lets make the associated comment clearer.

delta-find: move pre-filtering with other pre-filtering logic This is more consistent and will help use to be in a clean state before dealing with the "too large group" issue. As a side effect, the debug output now skip some useless cases, making it more useful.
