revlog-compression: use zstd by default (if available)
As see in changeset bb271ec2fbfb, zstd is 20% to 50% faster for reading and

back to zlib is zstd is not available on that plateform.

Checking the size/permissions/file-type of files stored in the dirstate after an update where the files are changed concurrently outside of hg's control. $ hg init repo $ cd repo $ echo a > a $ hg commit -qAm _ $ echo aa > a $ hg commit -m _ $ hg debugdirstate --no-dates n 644 3 (set |unset) a (re) $ cat >> $TESTTMP/dirstaterace.py << EOF > from mercurial import ( > extensions, > merge, > ) > def extsetup(ui): > extensions.wrapfunction(merge, 'applyupdates', wrap) > def wrap(orig, *args, **kwargs): > res = orig(*args, **kwargs) > with open("a", "w"): > pass # just truncate the file > return res > EOF Do an update where file 'a' is changed between hg writing it to disk and hg writing the dirstate.
