cmdutil: omit redundant "savecommitmessage()" in "tryimportone()" The preceding patch causes that "makememctx()" with "editor" argument saves (manually edited) commit message into ".hg/last-message.txt": saving itself is executed indirectly in "memctx.__init__()". This makes it redundant to invoke "savecommitmessage()" on caller side of "makememctx()". This patch omits such redundant "savecommitmessage()" invocation in "tryimportone()". "tryimportone()" uses one of "commiteditor" or "commitforceeditor" as "editor" argument, and this causes saving commit message always.

amend: use "editor" argument for "memctx.__init__" to save commit message This patch uses "editor" argument of "memctx.__init__" to save commit message, instead of explicit editor invocation and saving commit message by "localrepository.savecommitmessage()". By passing one of "commiteditor" or "commitforceeditor" as "editor", "memctx.__init__" saves commit message, even when editor invocation is not needed.

histedit: pass "editor" argument to "memctx.__init__()" for "collapse" command The preceding patch causes that "memctx.__init__()" with "editor" argument invokes editor and saves edited commit message into ".hg/last-message.txt". This patch passes "editor" argument to "memctx.__init__()" instead of explicit invocations of "commitforceeditor()" and "savecommitmessage()" for "collapse" command.

context: move editor invocation from "makememctx()" to "memctx.__init__()" This patch introduces "editor" argument to "memctx.__init__()", and moves editor invocation from "makememctx()" to "memctx.__init__()", to centralize editor invocation into "memctx" object creation. This relocation is needed, because "makememctx()" requires the "store" object providing "getfile()" to create "memfilectx" object, and this prevents some code paths from using "makememctx()" instead of "memctx.__init__()". This patch also invokes "localrepository.savecommitmessage()", when "editor" is specified explicitly, to centralize saving commit message into "memctx" object creation: passing "cmdutil.commiteditor" as "editor" can achieve both suppressing editor invocation and saving into ".hg/last-message.txt" for non empty commit messages.

localrepo: add "editor" argument to "tag()" Before this patch, "localrepository.tag()" doesn't take "editor" argument, and this prevents callers from passing "editor" argument to "localrepository.commit()" invoked internally. This patch adds "editor" argument to "localrepository.tag()" (and "_tag()", too), and makes "commands.tag()" invoke it with "editor" argument. This patch also omits explicit "localrepository.savecommitmesssage()" invocation, because "localrepository.commit()" will invoke specified "editor" and save edited commit message into ".hg/last-message.txt" automatically.

qrefresh: use "editor" argument of "commit()" instead of explicit "ui.edit()" Before this patch, "hg qrefresh" and "hg qfold" invoke "ui.edit()" explicitly to get commit message edited manually. This requires explicit "localrepository.savecommitmessage()" invocation to save edited commit message into ".hg/last-message.txt", because unexpected exception raising may abort command execution before saving it in "localrepository.commit()". This patch uses "editor" argument of "localrepository.commit()" instead of explicit "ui.edit()" invocation for "hg qnew" and "hg qfold" "localrepository.commit()" will invoke "desceditor()" function newly added by this patch, and save edited commit message into ".hg/last-message.txt" automatically. This patch passes not "editor" but "desceditor" to "commit()", because "hg qnew" and "hg qfold" require editor function to return edited message (and invoke "patchheader.setmessage()" with it) if not empty, or default message otherwise. This patch also avoids "not q.applied" check at "hg qrefresh --edit", because it is also checked in "queue.refresh()", and it is not needed to get commit message from patch header before "queue.refresh()".

qrefresh: relocate message/patch-header handling to delay message determination Before this patch, commit message for refreshed MQ changeset is determined, and written into refreshed patch file before "localrepository.commit()" invocation. This makes refactoring to use "editor" argument of "commit()" instead of explicit "ui.edit()" invocation in succeeding patch difficult. This patch relocates message/patch-header handling to delay message determination.

qnew: use "editor" argument of "commit()" instead of explicit "ui.edit()" Before this patch, "hg qnew" invokes "ui.edit()" explicitly to get commit message edited manually. This requires explicit "localrepository.savecommitmessage()" invocation to save edited commit message into ".hg/last-message.txt", because unexpected exception raising may abort command execution before saving it in "localrepository.commit()". This patch uses "editor" argument of "localrepository.commit()" instead of explicit "ui.edit()" invocation for "hg qnew". "localrepository.commit()" will invoke "desceditor()" function newly added by this patch, and save edited commit message into ".hg/last-message.txt" automatically. This patch passes not "editor" but "desceditor" to "commit()", because "hg qnew" requires editor function to return edited message if not empty, or default message otherwise. This patch applies "rstrip()" on "defaultmsg" at comparison between "nctx.description()" and "defaultmsg", because the former should be stripped by "changelog.stripdesc()" and the latter may have tail white spaces inherited from "patchfn".

histedit: use "editor" argument of "commit()" instead of explicit "ui.edit()" Before this patch, "message" action of "hg histedit" uses "ui.edit()" explicitly to get commit message edited manually. This requires explicit "localrepository.savecommitmessage()" invocation to save edited commit message into ".hg/last-message.txt", because unexpected exception raising may abort command execution before saving it in "localrepository.commit()". This patch uses "editor" argument of "localrepository.commit()" instead of explicit "ui.edit()" invocation for "message" action of "hg histedit" "localrepository.commit()" will invoke "editor()" function newly added in this patch, and save edited commit message into ".hg/last-message.txt" automatically.

test-pyflakes: detect undefined name error It should be able to catch the following mistakes at 2606e7f227f6: mercurial/exchange.py:590: undefined name 'UnknownPartError' mercurial/match.py:346: undefined name 'pat' mercurial/win32.py:365: undefined name '_ERROR_NO_MORE_FILES' tests/killdaemons.py:46: undefined name 'check'

run-tests: initialize global variables to suppress pyflakes warning

merge with stable

setup.py, make: avoid problems with outdated, existing hgext/__index__.py* "make clean" already removed __index__.py[cdo], but not the __index__.py (automatically generated by "python setup.py build_hgextindex"). "setup.py build_hgextindex" did not generate a new index if file __index__.py[cdo] already existed, because if __index__.py was removed, the compiled file containing the old information was imported and used. Generate an empty file (with a new timestamp to generate a new .py[cdo]) instead and make mercurial.extensions ignore the unset docs attribute. One of the problems was a failed test-help.t, to reproduce: $ rm hgext/__index__.py* $ echo 'docs = {"mq": "dummy"}' > hgext/__index__.py $ make test-help.t With this a "make clean" or "python setup.py build_hgextindex" helps.

factotum: initialize global variables to suppress pyflakes warning

color: don't fail on error messages when no curses (issue4237) The error only occured when Python didn't have curses - such as on Windows and when Python was built without curses support. No curses can also be emulated by (re)moving .../lib/python2.7/curses/ from the Python installation. It is left as an exercise to figure out exactly what changed in Mercurial that triggered this error.

win32: backout 1a9ebc83a74c This change conflicted with TortoiseHg's use of QFileSystemWatcher. Files which were being monitored (for file-system events) were unable to be reliably updated using util.atomictempfile. Often the update would error out in the middle of the process leaving neither the old or the new file in place. My guess is that _kernel32.CreateFileA() is triggering an exception that is not handled correctly within unlink()

rebase: empty revset should be a gentle no-op with exit code 1, not an error

largefiles: better handling of log from other working directory (issue4236) When invoked from another directory, the matchers m._cwd will be the absolute path. The code for calculating relative path to .hglf did not consider that and log would fail with weird errors and paths. For now, just don't do any largefile magic when invoked from other directories.

tests: add repository check for pyflakes test If this test was run from a tarball with no Mercurial repository, it would fail because 'hg manifest' didn't work.

spanset: directly use __contains__ instead of a lambda Spanset are massively used in revset. First because the initial subset itself is a repo wide spanset. We speed up the __and__ operation by getting rid of a gratuitous lambda call. A more long terms solution would be to: 1. speed up operation between spansets, 2. have a special smartset for `all` revisions. In the mean time, this is a very simple fix that buyback some of the performance regression. Below is performance benchmark for trival `and` operation between two spansets. (Run on an unspecified fairly large repository.) revset tip:0 2.9.2) wall 0.282543 comb 0.280000 user 0.260000 sys 0.020000 (best of 35) before) wall 0.819181 comb 0.820000 user 0.820000 sys 0.000000 (best of 12) after) wall 0.645358 comb 0.650000 user 0.650000 sys 0.000000 (best of 16) Proof of concept implementation of an `all` smartset brings this to 0.10 but it's too invasive for stable.

transaction: fix file descriptor leak for journal.backupfiles The journal.backupfiles descriptor wasn't being closed. This resulted in hgsubversion test runs having a bagillion descriptors open, which crashed on platforms with low open file limits (like OSX).

revset: also inline spanset._contained in __len__ For consistency with what happen in `__contains__`, we inline the range test into `__len__` too.

revset: inline spanset containment check (fix perf regression) Calling a function is super expensive in python. We inline the trivial range comparison to get back to more sensible performance on common revset operation. Benchmark result below: Revision mapping: 0) 3f83fc5cfe71 2.9.2 release 1) bcfd44abad93 current @ 2) This revision revset #0: public() 0) wall 0.010890 comb 0.010000 user 0.010000 sys 0.000000 (best of 201) 1) wall 0.012109 comb 0.010000 user 0.010000 sys 0.000000 (best of 199) 2) wall 0.012211 comb 0.020000 user 0.020000 sys 0.000000 (best of 197) revset #1: :10000 and public() 0) wall 0.007141 comb 0.010000 user 0.010000 sys 0.000000 (best of 361) 1) wall 0.014139 comb 0.010000 user 0.010000 sys 0.000000 (best of 186) 2) wall 0.008334 comb 0.010000 user 0.010000 sys 0.000000 (best of 308) revset #2: draft() 0) wall 0.009610 comb 0.010000 user 0.010000 sys 0.000000 (best of 279) 1) wall 0.010942 comb 0.010000 user 0.010000 sys 0.000000 (best of 243) 2) wall 0.011036 comb 0.010000 user 0.010000 sys 0.000000 (best of 239) revset #3: :10000 and draft() 0) wall 0.006852 comb 0.010000 user 0.010000 sys 0.000000 (best of 383) 1) wall 0.014641 comb 0.010000 user 0.010000 sys 0.000000 (best of 183) 2) wall 0.008314 comb 0.010000 user 0.010000 sys 0.000000 (best of 299) We can see this changeset gains back the regression for `and` operation on spanset. We are still a bit slowerfor the `public()` and `draft()`. Predicates not touched by this changeset.

ancestor: silence multiple ancestor warning outside of merge (issue4234) The current situation is a bit of a layering violation as merge-specific knowledge is pushed down to lower layers and leaks merge assumptions into other code paths. Here, we simply silence the warning with a hack. Both the warning and the hack will probably go away in the near future when bid merge is made the default.

revsetbenchmark: fix error raising We want to display the commands, not all arguments of the function. (The old code actually crash, failing to joining a list of lists.)

revset: fix revision filtering in spanset.contains (regression) The argument is `x` but the variable tested for filtering is `rev`. `rev` happens to be a revset methods, ... never part of the filtered revs. This method is now using `rev` for everything.

graft: do not use `.remove` on a smart set (regression) Revset calls use to return a list. Graft use to mutate that list. We cannot do this anymore leading to a crash when grafting multiple changeset with a revset. File ".../mercurial/commands.py", line 3117, in graft revs.remove(rev) AttributeError: '_addset' object has no attribute 'remove' We are late in code-freeze so we make the shortest possible fix by turning it back to a list.

help: clarify distinction among `contains`/`file`/`filelog` For a Mercurial new-comer, the distinction between `contains(x)`, `file(x)`, and `filelog(x)` in the "revsets" help page may not be obvious. This commit tries to make things more obvious (text based on an explanation from Matt in an FB group thread).

discovery: don't report all "unsynced" remote heads (issue4230) 8a9e0b523d2d made discovery more helpful - too helpful for some extreme use cases. Instead, we arbitrarily limit the list it at 4 and add 'or more'.

rebase: don't abort if we're asked to rebase an empty revset The documentation says we exit 1 if we have nothing to do, so avoid breaking that contract when we're passed an empty revset. This was changed in http://www.selenic.com/hg/rev/a259f7b488ab to improve the error message; keep the improved message, just not the abort.

largefiles: remove directories emptied after their files are moved (issue3515)

cmdserver: forcibly use L channel to read password input (issue3161) Command server is designed to use the channel protocol even if the server process is accessible to tty, whereas vanilla hg should be able to read password from tty in that case. So it isn't enough to swap sys.stdin: # works only if the server process is detached from the console sys.stdin = self.fin getpass.getpass('') sys.stdin = oldin or test isatty: # vanilla hg can't talk to tty if stdin is redirected if self._isatty(self.fin): return getpass.getpass('') else: ... Since ui.nontty flag is undocumented and command-server channels don't provide isatty(), this change won't affect the other uses of ui._isatty(). issue3161 also suggests to provide some context of messages. I think it can be implemented by using the generic templating function.

bundle2: gracefully handle hook abort We make sure any exceptions raised during the whole span of handling bundle2 processing are decorated. This let us catch exceptions raised by hooks prior to transaction commit.

bundle2: gracefully handle PushRaced error during unbundle Same drill again. We catch the PushRaced error, check if it cames from a bundle2 processing, if so we turn it into a bundle2 with a part transporting error information to be reraised client side.

bundle2: add an error message to push race error Errors with no explanations makes my uncle Bob sad.

bundle2: fix raising errors during heads checking If the heads on the server differ from the ones reported seen by the client at bundle time, we raise a PushRaced exception. However, the part raising the exception was broken. To fix it, we move the PushRaced class in the error module so it can be accessible everywhere without an import cycle. A test is also added to prevent regression.

bundle2: gracefully handle UnknownPartError during unbundle Same as for Abort error, we catch the error, encode it into a bundle2 reply (expected by the client) and stream this reply. The client processing of the error will raise the exception again.

bundle2: catch UnknownPartError during local push When doing local push, UnknownPartError from the server will be raised directly to the client. We need to catch them too.

bundle2: catch UnknownPartError during pull We narrow the exception catching while pulling.

bundle2: catch UnknownPartError during push We narrow the exception catching while unbundling the push reply.

bundle2: use a more specific UnknownPartError when no handler is found KeyError is very generic, we need something more specific for proper error handling.

bundle2: make error testing more modular We have more than Abort to test.

bundle2: gracefully handle abort during unbundle Clients expect a bundle2 reply to their bundle2 submission. So we catch the Abort error and turn it into a bundle2 containing a part transporting the exception data. The unbundling of this reply will raise the error again.

bundle2: decorate exception raised during bundle processing This is a small hack to help us do some graceful error handling in bundle2 without major refactoring. See embedded comment for details.
