revset-filelog: handle hidden linkrev for file missing for head (issue4490) The fix for linkrev pointing to hidden revision was crashing when the file was missing from head's manifest. We now properly handle this case. (yes I feel silly)

run-tests: automatically add (glob) to "saved backup bundle to" lines Avoid spending too much time adding (glob) after running run-tests -i. This doesn't handle all cases but it helps. The run-tests tests add a bit of escaping of trailing (glob) in the output to avoid interference from the outer test runner. The regexp for matching the output lines contains a group for making multiline substitute in a way that works with Python before 2.7.

transaction: use the right location when cleaning up backup file (issue4479) The location variable fetch from the loop and the one used to actually fetch it mismatched. We fix the name to ensure file outside of store are cleaned up.

revset: delay showing parse error for the revset alias until it is referred Before this patch, a problematic revset alias aborts execution immediately, even if it isn't referred in the specified revset. If old "hg" may be used too (for example, bisecting Mercurial itself), it is also difficult to write alias definitions using features newly introduced by newer "hg" into configuration files, because such alias definitions cause unexpected abortion at parsing revset aliases with old "hg". This patch delays showing parse error for the revset alias until it is actually referred at runtime. This patch detects referring problematic aliases in "_expandaliases" by examination of "revsetalias.error", which is initialized with the error message only when parsing fails. For usability, this patch also warns about problematic aliases, even if they aren't referred at runtime. This should help users to know potential problems in their alias definitions earlier.

revset: drop pre-lazyset optimization for stringset of subset == entire repo It was introduced at e44ebd2a142a, where spanset.__contains__() did not exist. Nowadays, we have to pay huge penalty for len(subset). The following example showed that OR operation could be O(n * m^2) (n: len(repo), m: number of OR operators, m >= 2) probably because of filteredset.__len__. revset #0: 0|1|2|3|4|5|6|7|8|9 0) wall 8.092713 comb 8.090000 user 8.090000 sys 0.000000 (best of 3) 1) wall 0.445354 comb 0.450000 user 0.430000 sys 0.020000 (best of 22) 2) wall 0.000389 comb 0.000000 user 0.000000 sys 0.000000 (best of 7347) (0: 3.2.4, 1: 3.1.2, 2: this patch)

largefiles: properly sync lfdirstate after removing largefiles The more aggressive synchronization of lfdirstate that was backed out in 1265a3a71d75 masked the problem where lfdirstate would hold an 'R' for a largefile that was added and then removed without a commit between. We could just conditionally call lfdirstate.drop() or lfdirstate.remove() here, but this also properly updates lfdirstate if the standin doesn't exist for the file somehow (i.e. call drop instead of remove). Without this change, the precommit status in the commit command immediately after the test change lists the removed (and never committed) largefile as 'R'. It can also lead to situations where the status command reports the same, long after the commit [1]. [1] http://www.selenic.com/pipermail/mercurial-devel/2015-January/065153.html

linkrev-filelog: handle filtered linkrev with no visible children (issue4307) If the file revision with a filtered linkrev does not have any (unfiltered) children, we cannot use it to bound the search for another introduction. Instead, we have to look at the file revision used by each head changeset. If one of them uses this file revision, we know there is another occurrence and we have a starting point. See inline comments for details. Adding some kind of permanent reference of all the introductions of a file revision instead of just the first one would be much better. But this is more difficult. I hope to take that into account in the next repository format.
