setdiscovery: avoid a Yoda condition Differential Revision: https://phab.mercurial-scm.org/D2646

setdiscovery: remove unnecessary sample size limiting Both _takequicksample() and _takefullsample() already limit their result to the request size, so there's no need to let the caller do that again. Differential Revision: https://phab.mercurial-scm.org/D2645

setdiscovery: remove initialsamplesize from a condition It seems more direct to compare the actual sample size. That way we can change the sample taken earlier in the code without breaking the condition. Differential Revision: https://phab.mercurial-scm.org/D2644

setdiscovery: back out changeset 5cfdf6137af8 (issue5809) As explained in the bug report, this commit caused a performance regression. The problem occurs when the local repo has very many heads. Before 5cfdf6137af8, we used to get the remote's list of heads and if these heads mostly overlapped with the local repo's heads, we would mark these common heads as common, which would greatly reduce the size of the set of undecided nodes. Note that a similar problem existed before 5cfdf6137af8: If the local repo had very many heads and the server just had a few (or many heads from a disjoint set), we would do the same kind of slow discovery as we would with 5cfdf6137af8 in the case where local and remote repos share a large set of common nodes. For now, we just back out 5cfdf6137af8. We should improve the discovery in the "local has many heads, remote has few heads" case, but let's do that after backing this out.

archival: tar file modes need to be sysstrs Differential Revision: https://phab.mercurial-scm.org/D2655

archival: fsdecode paths before passing to tar or zip objects Both of these traffic in unicodes for filenames on Python 3, and inspection of the tarfile module shows that it uses the filesystem encoding, so fsdecode is the right choice. Differential Revision: https://phab.mercurial-scm.org/D2654

lock: block signal interrupt while making a lock file On Windows where symlink isn't supported, util.makelock() could leave an empty file if interrupted immediately after os.open(). This empty lock never dies as it has no process id recorded. ld = os.open(pathname, os.O_CREAT | os.O_WRONLY | os.O_EXCL) # an interrupt may occur here os.write(ld, info) os.close(ld) This was a long-standing bug of TortoiseHg which runs a command-server and kills it by CTRL_C_EVENT, reported by random Windows users. https://bitbucket.org/tortoisehg/thg/issues/4873/#comment-43591129 At first, I tried to fix makelock() to clean up a stale lock file, which turned out to be hard because any instructions may be interrupted by a signal. ld = None try: # CALL_FUNCTION # os.open(...) # an interrupt may occur here # STORE_FAST # ld = ... ld = os.open(pathname, os.O_CREAT | os.O_WRONLY | os.O_EXCL) os.write(ld, info) ... return True except: if ld: ... os.unlink(pathname) return False So I decided to block signals by temporarily replacing the signal handlers so makelcok() and held = 1 will never be interrupted. Many thanks to Fernando Najera for investigating the issue.
