remotefilelog: remove strkwargs() The previous commit activated previously unused code paths on Python 3 and revealed that we were calling strkwargs() on a dict that already had str keys. The only caller of _forceprefetch() is _adjustlinknode() a few lines up and the static commonlogkwargs dict features str keys. Differential Revision: https://phab.mercurial-scm.org/D5958

remotefilelog: use raw strings when looking for variable names Keys in self.__dict__ and vars() are always str. So we need to use raw strings to ensure lookups work on Python 3. # skip-blame just r'' prefixes Differential Revision: https://phab.mercurial-scm.org/D5957

rust-cpython: binding for headrevs() This uses the core `dagops::retain_heads` to give a Rust implementation to `mercurial.dagop.headrevs`. Testing happens for now from `test-rust-ancestors.py` (for quick and minimal change), but it'd made more sense to put the binary index data elsewhere and to create a new test python module

rust-cpython: moved py_set() utility to conversion module We're still hoping to get rid of it eventually, but we're going to need it from outside the `ancestors` module before that.

rust: translated random test of missingancestors This is a Rust implementation of the random DAG generator and related incrementalmissingancestors tests against a naive brute force implementation. It is provided as an integration test, so that it won't run by default if any unit test fails. In case of a failed example, all needed information for reproduction is included in the panic message, (this is how `test_remove_ancestors_from_case1()` has been generated), as well as the random seed. The whole test is rerunnable by passing the random seed in the TEST_RANDOM_SEED environment variable. The other parameters (numbers of iterations) can be passed in the TEST_MISSING_ANCESTORS environment variable. An alternative would have been to expose to Python MissingAncestors<VecGraphs> but that would have meant pollution of the release build used from Python, whereas we do it in this changeset within the tests submodule Differential Revision: https://phab.mercurial-scm.org/D5417

debugrename: don't require at least one path I don't see a reason that it needs to require a path. Most commands match everything when no paths are given, but here you have to do something like `hg debugrename -r . .` (from the repo root) to match everything.

resolve: slightly simplify join expression by joining with empty strings Differential Revision: https://phab.mercurial-scm.org/D5938

resolve: respect ui.relative-paths also for warning messages I guess this should have been part of 72a9aacff645 (resolve: respect ui.relative-paths, 2019-01-29). Differential Revision: https://phab.mercurial-scm.org/D5937

addremove: respect ui.relative-paths I previously changed these code paths while trying to not change any behavior to avoid inconsistencies between them in the intermediate commits. They're now all ready to be switched over to respecting ui.relative-paths. Differential Revision: https://phab.mercurial-scm.org/D5936

windows: use util.localpath for repo-relative paths in getuipathfn() Now that we have a single place that translates from internal path representation (slash-separated) to UI representation (i.e. scmutil.getuipathfn()), let's switch that over to using util.localpath for absolute paths. I don't expect any test impact on Windows because we still respect ui.slash, which is set by the test runner. As Yuya pointed out, a997163e7fae (status: extract helper for producing relative or absolute path for UI, 2019-01-29) accidentally changed to slash-separated paths on Windows because it used used to use repo.pathto(f, cwd='') (which calls util.localpath()) and after that patch it just prints the filename without any transformation. This patch should fix that regression. Differential Revision: https://phab.mercurial-scm.org/D5935

walkchangerevs: obey allfiles parameter when taking the slow path When walkchangerevs sees that there's a pattern, it hits the slow path. The slow path in turn reverts to the old dumb grep behaviour of only looking at files changed at each revision. Therefore, a command such as hg grep -l --all-files '.*' 'glob:**' would show you all the nonempty files touched by the current revision. This modifies that behaviour to look at the manifest at each revision instead of the changed files in case that --all-files was requested.

test: stabilize test-wireproto-exchangev2.t flaky output When running the test suite with multiple processes, we often get flaky outputs, like here: https://ci.octobus.net/job/MercurialPy2/267/console ``` - received frame(size=0; request=1; stream=2; streamflags=; type=command-response; flags=eos) add changeset cd2534766bec add changeset e96ae20f4188 add changeset caa2a465451d + received frame(size=0; request=1; stream=2; streamflags=; type=command-response; flags=eos) ``` Instead of simply sorting the clone and pull output, I saved the output in a separate file and checked the `received frame` messages on one side and then the rest of the output on the other side. This way we conserve the order of messages as it seems important. Differential Revision: https://phab.mercurial-scm.org/D5897

zsh: fix `hg resolve` completion when in a subdirectory (issue6067) Differential Revision: https://phab.mercurial-scm.org/D5836

revset: add expectsize to check the size of a set `expectsize(<set>, <int>)` revset fails if `<set>` is not exactly `<int>` elements. `expectsize(<set>, <min>:<max>)` revset fails if `<set>` is not exactly between `<min>` and `<max>` inclusive. This then allows an alias for `hg next` to be `update -r one(children(.))` with sane failure behavior, and also makes some other scripting tasks a little less difficult.

match: delete unused root and cwd arguments to constructors (API) Most matchers no longer need the root and cwd arguments. patternmatcher and includematcher still need the root argument for subincludes. Differential Revision: https://phab.mercurial-scm.org/D5929

dirstate: call and cache os.getcwd() in constructor I'm about to make scmutil.matchfiles() not pass the root and cwd paths to match.exact(), since they no longer have any effect. That turned out to have the surprising effect of making some tests (test-rebase-scenario-global.t and test-removeemptydirs.t) crash when the working directory was removed. The problem was that my patch removed the call to repo.getcwd(), which caused the current working directory to not be cached in the dirstate as early as it was before. This patch fixes that by caching the current working directory in the dirstate constructor. Differential Revision: https://phab.mercurial-scm.org/D5928

py3: use raw strings and %d for formatting Before the string compares on Python 3 failed because we were comparing bytes to str. Using raw strings ensures we are always comparing str. While we're here, also use %d to format integers. Differential Revision: https://phab.mercurial-scm.org/D5925

diff: make --stat respect ui.relative-paths It would have been easy to make all diffs respect ui.relative-paths, but we don't want that since it makes the diff invalid. Perhaps it makes sense to do that with --noprefix since the point of that is to make paths that are easy to copy&paste, and the diff is already invalid anyway. But this patch just makes the --stat version respect the config option. The --stat view is not even close to a valid diff, so I think it makes sense to show the paths in more human-friendly form.

largefiles: get cwd and relative paths from repo instead of matcher As far as I can tell, the matcher returned from matchandpats() got its cwd from the context object, which in turn got it from the repo, so this should be equivalent. Differential Revision: https://phab.mercurial-scm.org/D5922

scmutil: remove special handling of pats==("",) in matchandpats() (API) I don't know under what circumstances we used to pass that value, but we don't seem to do it now. Differential Revision: https://phab.mercurial-scm.org/D5921

scmutil: respect ui.relative-paths in default match.badfn We should probably be passing in a uipathfn here instead, so the caller can get consistent output (between match.badfn and whatever else it prints). I think we should ideally remove the badfn from the matcher completely, but that's a different story. This patch is at least not making it worse.

addremove: use uipathfn instead of m.rel() for recorded similatity message When no path arguments are given to addremove, it generally prints absolute paths. However, before this patch, we would always print the "recording removal of foo as rename to bar (78% similar)" message with relative paths.

diff: respect ui.relative-paths for warning about path outside --root I set legacyrelativevalue=True rather than being based on what patterns the user passed (as the current match.uipath() does). I think it simply doesn't really matter for this message (there are not even any tests for it). Differential Revision: https://phab.mercurial-scm.org/D5905

largefiles: use uipathfn instead of match.{rel,uipath}() (API) All callers now pass in a uipathfn, so we can just use that instead of choosing the right match function. This also means that when we make add/remove respect ui.relative-paths, it will work for largefiles too. Differential Revision: https://phab.mercurial-scm.org/D5904

add: pass around uipathfn and use instead of m.rel() (API) For now, the uipathfn we pass around always prints relative paths just like before, so this should have no effect. Well, there's one little change: I also made the "skipping missing subrepository: %s\n" message relative. Differential Revision: https://phab.mercurial-scm.org/D5901

subrepo: (mostly) use relative path in "skipping missing subrepository" This is consistent with the other messages printed by these functions. Note that addremove is a little different and prints absolute (aka repo-relative) paths if no argument was given. Differential Revision: https://phab.mercurial-scm.org/D5900

subrepo: use relative path for "already tracked" message From 932de135041f (subrepo: warn when adding already tracked files in gitsubrepo, 2015-02-27): The file is printed with abs() to be consistent with how it is printed in workingctx, even though that is inconsistent with how added files are printed in verbose mode. However, a few year later, the same author wrote 7008f6819002 (context: name files relative to cwd in warning messages, 2017-07-11) and now it's inconsistent. This fixes that inconsistency. Differential Revision: https://phab.mercurial-scm.org/D5899

diff: make `hg diff --root=subrepo` work The root prefix is currently stripped before adding the subrepo prefix. It seems to me that if you run `hg diff --root=subrepo` and a subrepo/ path is visited (say "subrepo/foo"), then the path generated for the diff would initially be just "foo" and we then fail (if the developer warning is active) to strip the "subrepo/" from the path. It seems like we should first add the prefix in order to produce a path that's relative to the top-level repo, and then we can remove the root prefix from that. There are no tests for this, it seems, and I don't care enough to add one. Differential Revision: https://phab.mercurial-scm.org/D5895

patch: replace "prefix" and "relroot" arguments by "pathfn" (API) The two arguments serve a very similar purpose: "relroot" is stripped from the front of the path, and then "prefix" (a subrepo path) is added (also to the front). Passing in a function that does that is more generic and will make it easier to respect ui.relative-paths in later patches (don't worry, I'm not going to respect that option for regular patches, only for --stat). I'm deliberately not calling it "uipathfn", because it's generally for producing valid diffs (including when prefix is non-empty), so things like using backslash on Windows is not an option.
