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.

revsetbenchmark: get revision to benchmark in a function And move it to proper subprocess call.

revsetbenchmark: convert revision display to proper subprocesscall

revsetbenchmark: convert performance call to proper subprocess call

revsetbenchmark: convert update to proper subprocess call

revsetbenchmark: fix semicolon

revsetbenchmark: simplify and convert the script to python The script is now in python. That translation is very raw, more improvement to comes: The "current code" and "base" entry have been dropped. This is trivial to get same result using a tagged revision or "." in the list of benchmarked revision.

revsetbenchmapi: fix template The revision description missed an \n

perf: unroll the result in perfrevset With the new lazy revset implementation, we need to actually read all elements to trigger all the computations. Otherwise a no-op if of course much faster than the full work.

_addset: add a __len__ method Back in the time where repo.revs(...) returned a list, calling `len(...)` on the result was quite common. We reinstall this on _addset. There is absolutely no easy way to test this from the command line. The commands using this in the evolve extension will eventually land into core.

bundle2: implement the mandatory/advisory logic for parameter Parameter starting with an upper case are mandatory, the one starting with a lower case are advisory and may be ignored.

bundle2: print debug information during unbundling The unbundler class is now feed with an ui object and use it to transmit data about the unbundling process.

bundle2: print debug information during bundling The bundler class is now feed with an ui object and use it to transmit data about the bundling process.

bundle2: add ability to write to a file to the test Next changesets are about improving debug output during bundling. We won't be able to simply bundle to stdin in this case. The bundle2 stream would be interleaved with debug output.

subrepo: factor out Git version check to add doctests Followup to 6a2acb0d9352::e5641536e4d5.

contrib: add "hgperf" command to measure performance of commands easily Newly added "hgperf" command repeats "dispatch.runcommand()" for specified Mercurial command and measure performance of it in the same manner of "contrib/perf.py" extension. Users (mainly developers) can examine performance of the target command easily, without adding new entry for it to "contrib/perf.py" extension.

grep: exit loop immediately, if matching is found in the file for "hg grep -l" Before this patch, internal function "display()" of "hg grep" is not efficient for "-l"/"--files-with-matches", because loop is continued, even after the first matching is found in the specified file. This patch exits loop immediately, if matching is found for "--files-with-matches". In this case, "before is None" is equal to "opts.get('files_with_matches')".

grep: use "found" instead of "filerevmatches" examination for efficiency Before this patch, internal function "display()" of "hg grep" stores whether matching is already found or not into the dictionary "filerevmatches" by "(fn, rev)" tuple as the key. But this is redundant, because: - "filerevmatches" is local variable of "display()", so each "display()" invocations don't affect others - both "fn" and "rev" (gotten from "ctx" argument) are never changed in each "display()" invocations Then, "filerevmatches" should have only one entry at most, and "(fn, rev) in filerevmatches" should be equal to "found". This patch uses "found" instead of "filerevmatches" examination for efficiency.
