fncache: remove the rewriting logic The fncache could rewrite itself during a read operation if it noticed any entries that were no longer on disk. This was problematic because it caused Mercurial to perform write operations outside the scope of a lock or transaction, which could interefere with any other pending writes. This will be replaced in a future patch by logic that cleans up the fncache as files are deleted during strips.

pull: prevent duplicated entry in `op.pulledsubset` In the bare pull case we could add the same node multiple time to the `pulloperation.pulledsubset`. Beside being a bit wrong this confused the new revset implementation of `revset._revancestor` into giving bad result. This changeset fix the pull operation part. The fix for the revset itself will come in another changeset.

bundle2: part params

bundle2: support for bundling and unbundling payload We add the ability to bundle and unbundle a payload in parts. The payload is the actual binary data of the part. It is used to convey all the applicative data. For now we stick to very simple implementation with all the data fit in single chunk. This open the door to some bundle2 testing usage. This will be improved before bundle2 get used for real. We need to be able to stream the payload in multiple part to exchange any changegroup efficiently. This simple version will do for now. Bundling and unbundling are done in the same changeset because the test for parts is less modular. However, the result is not too complex.

backout: correct commit status of no changes made (BC) (issue4190) If backout generated no changes to commit, it showed wrong status, "changeset <target> backs out changeset <target>", and raised TypeError with -v option. This changes the return code to 1, which is the same as "hg commit" and "hg rebase".

i18n: fix "% inside _()" problems Before this patch, "contrib/check-code.py" can't detect these problems, because the regexp pattern to detect "% inside _()" doesn't suppose the case that format string consists of multiple string components concatenated implicitly or explicitly, This patch does below for that regexp pattern to detect "% inside _()" problems in such case. - put "+" into separator part ("[ \t\n]") for explicit concatenation ("...." + "...." style) - enclose "component and separator" part by "(?:....)+" for concatenation itself ("...." "...." or "...." + "....")

i18n: fix "% inside _()" problems Before this patch, "contrib/check-code.py" can't detect these problems, because the regexp pattern to detect "% inside _()" doesn't suppose the case that the format string and "%" aren't placed in the same line. This patch replaces "\s" in that regexp pattern with "[ \t\n]" to detect "% inside _()" problems in such case. "[\s\n]" can't be used in this purpose, because "\s" is automatically replaced with "[ \t]" by "_preparepats()" and "\s" in "[]" causes nested "[]" unexpectedly.

bundle2: support unbundling empty part We augment the unbundler to make it able to unbundle the empty part we are now able to bundle.

revset: raise ValueError when calling min or max on empty smartset min([]) raise a ValueError, we do the same thing in smartset.min() and smartset.max() for the sake of consistency. The min/amax test are greatly improved in the process to prevent this familly of regression

revpair: smartset compatibility Since recent revset changes, revrange now return a smartset. This smart set probably does not support indexing (_addset does not). This led to crash. Instead when the smartset is ordered we use the `min` and `max` method of smart set. Otherwise we turn is into a list and use indexing on it. The tests have been updated to catch such regression.

revsetbenchmark: add entry for ::rev:: Revsets of the form ::rev:: were identified as the source behind the regressions in issue 4201. Ensure we have explicit coverage of that revset.

merge with stable This should correct an earlier couple of bad merges (5433856b2558 and 596960a4ad0d, now pruned) that accidentally brought in a change that had been marked obsolete (244ac996a821).

tests: use TESTTMP instead of TESTDIR In 57d0c8c3b947, f042d4b263f4, 1e686e55780c, and 5d22cadd1938, new tests were added that used TESTDIR instead of TESTTMP thereby leading to polluting the working directory with these temporary files. Now, we use TESTTMP so that they will be cleaned up properly.

hg: introduce "wirepeersetupfuncs" to setup wire peer by extensions (issue4109) Since changeset 6f72e7d28b35, "reposetup()" of each extensions is invoked only on repositories enabling corresponded extensions. This causes that largefiles specific interactions between the repository enabling largefiles locally and remote (wire) peer fail, because there is no way to know whether largefiles is enabled on the remote repository behind the wire peer, and largefiles specific "wireproto functions" are not given to any wire peers. To avoid this problem, largefiles should be enabled in wider scope than each repositories (e.g. user-wide "${HOME}/.hgrc"). This patch introduces "wirepeersetupfuncs" to setup wire peer by extensions already enabled. Functions registered into "wirepeersetupfuncs" are invoked for all wire peers. This patch uses plain list instead of "util.hooks" for "wirepeersetupfuncs", because the former allows to control order of function invocation by order of extension enabling: it may be useful for workaround of problems with combination of enabled extensions

templater: raise error for unknown func Previously, if a template '{foo()}' was given, the buildfunc would not be able to match it and hit a code path that would not return so it would error out later in the templater stating that NoneType was not iterable. This patch makes sure that a proper error is raised so that the user can be informed. Tests have been updated.

bundle2: support bundling of empty part (with a type) Here start the work on bundle2 parts. Our first step is to be able to bundle a simplistic part that just have a type, no parameters, empty payload.

revsetbenchmark: add a summary at the end of execution The summary list timing per revset making it much more easier to compare revision to each other.

revsetbenchmark: retrieve the benchmark value in python We retrieve the output of the perf extension and print it ourself. This open the door to processing of this data in the script.
