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
