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.

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.

reachableroots: use smartset min smartset min are likely to be optimised, cached or other magical property.

graphmod: stop building a list out of branchgroupiter Not only does this defeat the purpose of having `branchgroupiter` an iterable, but this also makes revs something else than a smartset preventing to use revs.min() in the call to reachablerevs.

reachableroots: sort the smartset in the pure version too Changeset be8a4e0800d8 uses smartset lazy sorting for the C version. We need to apply the same to the pure version for consistency. This is fixing the tests with --pure.

builddeb: actually run make when building the deb (issue4778) As of this change, we no longer produce broken debs, but I've already got followups written that will produce much more standard-looking packages and test the resulting packages.

docker-debian-jessie: fix errant mkdir

makefile: rename debian-jessie to deb `make debian-jessie` was a poor name choice on my part, because it really builds a package for the current debian platform, whatever that happens to be, rather than a specific platform. Rename it to just `make deb` so that it's a little clearer. As a result, it now places built debs in a "debian-unknown" directory.

run-tests: ignore failed removal of nonexistent installerrs When running tests with -j100 or so on a large machine, I see this os.remove call failing semi-regularly. Since it's not really a problem when the file is already gone, just suppress the error in that case.
