simplemerge: take over formatting of label from `filemerge` The padding we do of conflict labels depends on which conflict marker style is used. For two-way conflict markers (the default), the length of the base label shouldn't matter. It does before this patch, however. This patch moves the formatting from `filemerge` to `simplemerge`. The latter knows which conflict marker style to use, so it can easily decide about the padding. This change will allow us to use more descriptive "base" labels without causing illogical padding in 2-way markers. I'll do that next. One wrinkle is that we pass the same labels to external merge tools. I decided to change that in this patch to be simpler: no padding, and no ellipsis to fit within 80 columns. My reasoning is that the typical external, 3-or-4-panel merge tool doesn't show the labels on top of each others, so the padding doesn't make sense there. The ellipsis is probably not necessary because the external tools probably have their own way of dealing with long labels. Also, we limit them to "80 - 8" to fit the "<<<<<<< " before, which is almost definitely not what an external tool would put there. Differential Revision: https://phab.mercurial-scm.org/D12019

filemerge: pass `simplemerge.MergeInput` to tool functions Differential Revision: https://phab.mercurial-scm.org/D12018

filemerge: work with `simplemerge.MergeInput` in `filemerge()` We currently pass around pairs of file context objects and labels between functions in the `filemerge` module. I plan to pass around `simplemerge.MergeInput` instead. This patch prepares for that by using the type internally in `filemerge.filemerge()`.

filemerge: set default labels a little earlier By setting the default labels a little earlier, we can rely on them always being set, as far as I can tell.

filemerge: remove unused arguments from `_merge()` Differential Revision: https://phab.mercurial-scm.org/D12014

simplemerge: take arguments as annotated context objects The labels we put in conflict markers are formatted so the part before the ':' (typically says things like "local") is padded so the ':' is aligned among the labels. That means that if you specify a long label for "base" but the conflict marker style is "merge" (i.e. 2-way), the other two will have unwanted padding. We often don't specify a label for the base, so we don't notice the problem (and it may very well be that it didn't exist before my D11972). I think the best fix is to pass the labels along with the context objects, so the low-level code that switches on the marker style to use (i.e. `simplemerge`) can do the formatting. This patch starts doing that by passing a fully-formatted label to `simplemerge`. A coming patch will move the formatting to `simplemerge`. Differential Revision: https://phab.mercurial-scm.org/D12013

blackbox: change year in logs to ISO 8601 format AFAIK, year/month/day is not a format than anyone uses. It seems more sensible to me to use ISO 8601, as that's standard and unambiguously year-month-day. Compatibility-wise, I think it's acceptable to change the default format. It's most for human consumption. It's plausible that a few tools parse this format, but it has already changed in the past (for instance to add the current revision).

blackbox: add milliseconds to blackbox logs by default The current second granularity is often not specific enough to determine whether an hg command is happening before or after some other event.

merge: consider the file merged when using :merge-{local,other} Returning `None` from `simplemerge()` means that the caller interprets it as "no merge was necessary (because two sides matched)". See 6217040b2780 and issue2680 for some background. However, `simplemerge()` shouldn't even get called in such scenarios, and returning `None` means that the file is not considered merged, even though the contents actually were.

simplemerge: change _minimize() to minimize a single conflict `_minimize()` is weird in that it changes `a_lines` and `b_lines` but leaves `base_lines` unchanged, which means they'll be inconsistent. That was fine because the caller never used `base_lines`. With the recent refactorings of this code, we can now make this function cleaner by having it minimize a single conflict and not care about `base_lines`. This also makes the code simpler and makes the code for each `render_*()` function more similar. Differential Revision: https://phab.mercurial-scm.org/D11981

simplemerge: make minimize() a free function IMO, `Merge3Text` should be about merging text without knowing about conflict markers.

simplemerge: use same newline detection for :mergediff as for :merge[3] The `:merge` and `:merge3` markers used the newline style detected from the base input.

simplemerge: clarify names of functions that render conflict markers Differential Revision: https://phab.mercurial-scm.org/D11975

simplemerge: convert `merge_lines()` away from generator We always consume all the lines and put them in a list anyway.

simplemerge: use 3-way markers if mode=='merge3', ignoring number of labels Before this patch, we use a combination of `mode` and `labels` to decide which marker style to use. That's mostly my own fault because I was the one who added the `mergediff` as a "mode" instead of adding a separate argument for marker style. Still, let's make these arguments more orthogonal by ignoring the number of labels when deciding which marker style to use. This refactoring makes it a little clearer in the simplemerge *extension* that passing more than 2 `--label` arguments changes the marker style.

We need to `normpath` at least the `subpath` because of "http://user:***@localhost:$HGPORT/main/../sub" in `test-subrepo-relative-path.t`. Keep the `os.path` flavor for handling filesystem based remote repos, since this string is also displayed.

simplemerge: make `localorother` a "mode" instead of a separate thing `simplemerge()` takes a `mode` argument, which can be "union", "merge" or "mergediff", and a `localorother` argument, which can be `None`, "local", or "other". The two options are not at all orthogonal -- most combinations don't make sense. Also, at least "union", "local", and "other" are very closely related. Therefore, it makes sense to combine them into one. It probably makes sense to split the `mode` argument into `resolve` and `marker_style`, where the former can be `None`, "union", "local", or "other", and the latter can be "merge", "merge3", "mergediff", or "minimize".

simplemerge: stop merging file flags As 384df4db6520 (merge: merge file flags together with file content, 2013-01-09) explains, we shouldn't do a 3-way merge of the symlink. However, since 84614212ae39 (flags: actually merge flags in simplemerge, 2020-05-16), we do that in `simplemerge.simplemerge()`. What's more, the merging of the executable flag there isn't actually necessary; it was made a no-op by the very next commit, i.e. 4234c9af515d (flags: read flag from dirstate/disk for workingcopyctx (issue5743), 2020-05-16). I found the overall flag-merging code (not the bit in `simplemerge.py`) very hard to follow, but I think I now finally understand how it works. `mergestate.resolve()` calculates the merged file flags and sets them on the local side of the merge (confusingly by calling `_restore_backup()`). Then it calls `filemerge.filemerge()`, which in turn calls `simplemerge.simplemerge()` (if premerge is enabled). That means that the flags on the local side `fcs.flags()` are already correct when the flag-merging code in `simplemerge.simplemerge()` runs. Interestingly, that code still works when the local side already has the merged value, it just doesn't change the value. Here's a truth table to explain why: ``` BLOMCAR 0000000 0011111 0101011 0111111 1000000 1010000 1100000 1111101 ``` B: Base L: Local O: Other M: Merged flags from `mergestate.resolve()`, i.e. what's called "local" when we get to `simplemerge.simplemerge()` C: `commonflags` in `simplemerge.simplemerge()`, i.e. `M & O` A: `addedflags` in `simplemerge.simplemerge()`, i.e. `(M ^ O) - B` R: Re-merged flags `simplemerge.simplemerge()`, i.e. `C | A` As you can see, the re-merged flags are always unchanged compared to the initial merged flags (R equals M). Therefore, this patch effectively backs out 84614212ae39. (I might later refactor this code to have the flags explicitly passed in.) `simplemerge.simplemerge()` is also called from `contrib/simplemerge.py`, but that code never passes any flags.

pytype: stop excluding wireprotoserver.py The `config` entry is a 2 part tuple, which has `__iter__()`: File "/mnt/c/Users/Matt/hg/mercurial/wireprotoserver.py", line 253, in _availableapis: No attribute '__iter__' on Callable[[Any, Any], Any] [attribute-error] In Union[Callable[[Any, Any, Any, Any, Any], None], Callable[[Any, Any], Any]] File "/mnt/c/Users/Matt/hg/mercurial/wireprotoserver.py", line 253, in _availableapis: No attribute '__iter__' on Callable[[Any, Any, Any, Any, Any], None] [attribute-error] In Union[Callable[[Any, Any, Any, Any, Any], None], Callable[[Any, Any], Any]] Differential Revision: https://phab.mercurial-scm.org/D11930

pytype: stop excluding pycompat.py Whatever issues were here seem to have been previously fixed. Differential Revision: https://phab.mercurial-scm.org/D11929

procutil: avoid an uninitialized variable usage on tempfile exception If `pycompat.unnamedtempfile()` raises an exception, it would have called `stdin.close()` in the `finally` block without it being initialized first. Differential Revision: https://phab.mercurial-scm.org/D11928

pytype: stop excluding procutil.py This avoids these false warnings: File "/mnt/c/Users/Matt/hg/mercurial/utils/procutil.py", line 78, in <module>: No attribute 'register' on Type[io.BufferedIOBase] [attribute-error] File "/mnt/c/Users/Matt/hg/mercurial/utils/procutil.py", line 117, in <module>: No attribute 'register' on Type[io.IOBase] [attribute-error] File "/mnt/c/Users/Matt/hg/mercurial/utils/procutil.py", line 770, in runbgcommandpy3: No attribute 'close' on int [attribute-error] In Union[IO[Union[bytes, str]], int] Differential Revision: https://phab.mercurial-scm.org/D11927

pytype: stop excluding chgserver.py This teaches pytype about some lazy initialization, and avoids the following: File "/mnt/c/Users/Matt/hg/mercurial/chgserver.py", line 666, in _checkextensions: No attribute '_hashstate' on chgunixservicehandler [attribute-error] File "/mnt/c/Users/Matt/hg/mercurial/chgserver.py", line 672, in _checkextensions: No attribute '_hashstate' on chgunixservicehandler [attribute-error] File "/mnt/c/Users/Matt/hg/mercurial/chgserver.py", line 677, in _bind: No attribute '_realaddress' on chgunixservicehandler [attribute-error] File "/mnt/c/Users/Matt/hg/mercurial/chgserver.py", line 683, in _bind: No attribute '_realaddress' on chgunixservicehandler [attribute-error] File "/mnt/c/Users/Matt/hg/mercurial/chgserver.py", line 686, in _createsymlink: No attribute '_baseaddress' on chgunixservicehandler [attribute-error] File "/mnt/c/Users/Matt/hg/mercurial/chgserver.py", line 686, in _createsymlink: No attribute '_realaddress' on chgunixservicehandler [attribute-error] File "/mnt/c/Users/Matt/hg/mercurial/chgserver.py", line 688, in _createsymlink: No attribute '_baseaddress' on chgunixservicehandler [attribute-error] File "/mnt/c/Users/Matt/hg/mercurial/chgserver.py", line 689, in _createsymlink: No attribute '_realaddress' on chgunixservicehandler [attribute-error] File "/mnt/c/Users/Matt/hg/mercurial/chgserver.py", line 690, in _createsymlink: No attribute '_baseaddress' on chgunixservicehandler [attribute-error] Differential Revision: https://phab.mercurial-scm.org/D11926

pytype: stop excluding webcommands.py I have no idea why, but asserting that each value added to `emptydirs` is not None didn't fix this: File "/mnt/c/Users/Matt/hg/mercurial/hgweb/webcommands.py", line 621, in dirlist: Function bytes.join was called with the wrong arguments [wrong-arg-types] Expected: (self, iterable: Iterable[bytes]) Actually passed: (self, iterable: List[None]) Differential Revision: https://phab.mercurial-scm.org/D11924

pytype: stop excluding patch.py The underlying `email.generator.BytesGenerator` is documented as requiring an `fp` that accepts bytes, so I'm not sure why pytype is getting confused: File "/mnt/c/Users/Matt/hg/mercurial/patch.py", line 112, in msgfp: Function Generator.__init__ was called with the wrong arguments [wrong-arg-types] Expected: (self, outfp: TextIO, ...)

pytype: stop excluding statprof.py This seems to have worked fine before (at least on Linux). We could just add suppression comments, but this file already imports from the mercurial package, which seems to prevent this from running as a standalone program because of the relative import of `pycompat`. PyCharm isn't happy either way.
