templater: drop unneeded destructuring of argument tuple at buildfilter Because evalfuncarg() accepts an argument tuple, there is little meaning to pass (func, data, filt) in place of ((func, data), filt).

templater: extract helper that evaluates filter or function argument It will be used to get a date tuple from an argument. Perhaps some of "stringify(args[n][0], ...)" can be replaced by this function.

contrib: add showstack extension This allows getting a Python stack trace at any time on Unix by hitting Ctrl-\ (or Ctrl-T on BSDs). Useful for debugging mysterious hangs on the fly.

hgweb: fix trust of templates path (BC) Long ago we disabled trust of the templates path with a comment describing the (insecure) behavior before the change. At some later refactor, the code was apparently changed back to match the comment, unaware that the intent of the comment was to describe the behavior to avoid. This change disables the trust and updates the comment to explicitly say not only what the old problem was, but also that it was in fact a problem and the action taken to prevent it. Impact: prior to this change, if you had a UNIX-based hgweb server where users can write hgrc files, those users could potentially read any file readable by the web server. This is marked as a backwards compatibility issue because people may have configured templates without proper trust settings. Issue spotted by Greg Szorc.

wix: avoid an abort with 'hg help -k foo' Previously: $ /c/Program\ Files/Mercurial/hg help -k merge-tools abort: No such file or directory: c:\Program Files\Mercurial\help\scripting.txt The Inno installer seems OK, but the TortoiseHg required the same fix. That got queued with an additional change of 'helpFolder.guid' in guids.wxi (probably by Steve). I'm not sure if that is necessary here too.

revlog: add an aggressivemergedelta option This adds an option for delta'ing against both p1 and p2 when applying merge revisions and picking whichever is smallest. Some before and after stats on manifest.d size: internal large repo: before: 1.2 GB after: 930 MB mozilla-central: before: 261 MB after: 92 MB

revlog: change generaldelta delta parent heuristic The old generaldelta heuristic was "if p1 (or p2) was closer than the last full text, use it, otherwise use prev". This was problematic when a repo contained multiple branches that were very different. If commits to branch A were pushed, and the last full text was branch B, it would generate a fulltext. Then if branch B was pushed, it would generate another fulltext. The problem is that the last fulltext (and delta'ing against `prev` in general) has no correlation with the contents of the incoming revision, and therefore will always have degenerate cases. According to the blame, that algorithm was chosen to minimize the chain length. Since there is already code that protects against that (the delta-vs-fulltext code), and since it has been improved since the original generaldelta algorithm went in (2011), I believe the chain length criteria will still be preserved. The new algorithm always diffs against p1 (or p2 if it's closer), unless the resulting delta will fail the delta-vs-fulltext check, in which case we delta against prev. Some before and after stats on manifest.d size. internal large repo old heuristic - 2.0 GB new heuristic - 1.2 GB mozilla-central old heuristic - 242 MB new heuristic - 261 MB The regression in mozilla central is due to the new heuristic choosing p2r as the delta when it's closer to the tip. Switching the algorithm to always prefer p1r brings the size back down (242 MB). This is result of the way in which mozilla does merges and pushes, and the result could easily swing the other direction in other repos (depending on if they merge X into Y or Y into X), but will never be as degenerate as before. I future patch will address the regression by introducing an optional, even more aggressive delta heuristic which will knock the mozilla manifest size down dramatically.

revlog: move textlen calculation to be above delta chooser This moves the textlen calculation to be above the delta chooser. Since textlen is needed for calling isgooddelta, we need it above the delta chooser so future patches can call isgooddelta.

revlog: move delta check to it's own function This moves the delta vs fulltext comparison to its own function. This will allow us to reuse the function in future patches for more efficient delta choices. As a side effect, this will also allow extensions to modify our delta criteria.

monoblue: add archive links on summary page

help: distinguish sections when multiple match (issue4802)

merge with stable

hghave: add a check for docker support This currently refuses to operate if on a non-Linux host. I suspect that Docker running on FreeBSD 11 or on an Illumos derivative would work fine, but I don't have ready access to such a system. On OS X using boot2docker (I used a hacky xhyve-based one for testing), it won't work because $TESTTEMP doesn't end up inside the set of directories that get forwarded to the boot2docker VM, so you can't actually drop debs in the $TESTTEMP at all. It would be possible (probably even trivial) to hack around this by using a randomly-named temporary directory inside the working directory, but that seems unlikely to be useful enough to justify the ugliness.

hghave: add a check for debian packaging tools

run-tests: add support for marking tests as very slow I want to add tests for our packaging rules, but those necessarily run a whole build, or possibly two if both native packaging and docker are available. This lets us flag such tests with a `#require slow` so that they don't unnecessarily slow down normal test runs.

builddeb: rework how output dir and platform are specified This makes it possible to write tests for both builddeb and dockerdeb that actually build .debs and then sanity check the contents.

parsers: fix two cases of unsigned long instead of Py_ssize_t We had to do this before because Python 2.4 didn't understand the n format specifier in Py_BuildValue and friends. We no longer have that problem.

templatefilters: remove redundant 'date' and 'strip' filters These filters are defined as 'date()' and 'strip()' functions. Help messages are moved to the corresponding functions.

templater: introduce unified filter syntax for unary functions "filter(expr)" is allowed already. This patch adds the opposite, "expr|func".

templater: inline getfilter() to buildfilter() This prepares for the unified filter syntax that will be introduced by the next patch.

clone: fix updaterev to update to latest branch changeset (issue4528) Before this patch if clone --updaterev points to branch which head on src repo wasnt in dest repo, clone updated dest repo to default branch. After applying this patch, if changeset from src repo pointing at given branch is not in dest repo, it searches for changeset pointing for given branch locally in dest repo. Lookup in destination repo: 559: uprev = destrepo.lookup(update) is wrapped by try/except block to preserve current behaviour when given revset to -u is not found - it will not fail,but silently update dest repo to head of default branch.

revsets: makes follow() supports file patterns (issue4757) (BC) Before this patch, follow only supports full, exact filenames. This patch makes follow argument to be treated like file pattern same way like log treats their arguments. It preserves current behaviour of follow() matching paths relative to the repository root by default.

i18n-ja: synchronized with b930d4ef7739

histedit: improve discoverability of edit commit message

revset: cache smartset's min/max As the content of a smartset never changes, min and max will never change either. This will save us time when this function is called multiple times. This is relevant for issue4782 but does not fix it.

spelling: behaviour -> behavior

glossary: fixup use of periods at end of entries * Include trailing period for entries * Move trailing period inside quotations for example sentences

histedit: fix grammar for help for safety aborts

revset: mark reachablerootspure as private

reachableroots: construct and sort baseset in revset module This can remove the dependency from changelog to revset, which seems a bit awkward for me.
