help: fix a py3 error interpolating Set into b'%s' I can't reproduce it, but a coworker hit this with `hg help -v` with 6.2.3: ... File "mercurial\help.pyc", line 865, in helplist TypeError: %b requires a bytes-like object, or an object that implements __bytes__, not 'set' I can confirm that the original expression fails in `hg debugshell`, and the new one works. The second instance was found by searching for "%s", but PyCharm detects a lot of variables as Any type, so I have no idea if there are other lurking problems.

Added signature for changeset c890d8b8bc59

Added tag 6.3.1 for changeset c890d8b8bc59

relnotes: add 6.3.1

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
