py3: byteify the opener option to use `rust.index` to allow Rust revlogs It looks like this corresponds to the byteified key written in localrepo in 8042856c90b6. Differential Revision: https://phab.mercurial-scm.org/D7818

graft: use revset for intersecting with ancestor set This addresses a TODO added in a1381eea7c7d (graft: do not use `.remove` on a smart set (regression), 2014-04-28). Differential Revision: https://phab.mercurial-scm.org/D7806

graft: don't remove from a list in a loop This addresses a TODO added in a1381eea7c7d (graft: do not use `.remove` on a smart set (regression), 2014-04-28). I couldn't measure any speedup. Differential Revision: https://phab.mercurial-scm.org/D7805

tests: avoid grafting the same change over and over The test case added in a1381eea7c7d (graft: do not use `.remove` on a smart set (regression), 2014-04-28) added a test case that grafted the same change (renaming 'a' to 'b') three times over. It had description "graft works on complex revset", but AFACT, all that it cared about was that some ancestor of the working copy was in the set of revisions to graft. So this patch changes the test to do that instead. (I plan to later make it so that grafting these renames on top of each won't create the empty commits they currently create.)

py3: byteify some `ui.configbool()` parameters This popped up in 8042856c90b6. Differential Revision: https://phab.mercurial-scm.org/D7817

rust-discovery: type alias for random generator seed It just makes our life easier Differential Revision: https://phab.mercurial-scm.org/D7715

tests: split out another ~1/2 of test-graft.t The tests involving renames were also quite independent from the rest. Differential Revision: https://phab.mercurial-scm.org/D7803

tests: split out ~1/3 of test-graft.t test-graft.t is ~2400 lines and takes 34s to run. This patch moves the last ~1/3 of it to a separate file. The parts now run in 22s + 13s. On top of that, we can remove the #testcases from the old file, so it's only 22s + 2*13s instead of the 2*34s it was before. Differential Revision: https://phab.mercurial-scm.org/D7802

overlwayworkingctx: remove doubly bad reference to wrapped ctx for copies `_wrappedctx` lives on overlwayworkingctx, not on the repo object, so we should access it as `._wrappedctx`, not `._repo._wrappedctx`. More importantly, the overlayworkingctx is relative to its base, not including it, so the copies returned should not include copies made in the base.

movedirstate: get copies from dirstate before setting parents Setting dirstate parents can modify the copies recorded in the dirstate when there are two dirstate parents. I don't think we ever call movedirstate() when there is more than one parent, but it seems clearer to get the copies from the dirstate first anyway.

fix: convert clang-format-ignorelist to use wildcards It's very brittle to specify the exact filenames for these vendored/thirdparty libraries; when there's an upgrade, it's likely not going to be updated. Differential Revision: https://phab.mercurial-scm.org/D7619

packaging: update Ubuntu docker build dependencies to Python 3 Changeset 7574ccd87200f02e updated the Debian docker builds to Python 3. In doing so, the Ubuntu docker-based builds broke, as the Dockerfile does not include the new dependencies as specified in `contrib/packaging/debian/control`. This commit changes the dependencies in the Ubuntu Dockerfile template to their Python 3 equivalents, fixing `make docker-ubuntu-bionic`. Differential Revision: https://phab.mercurial-scm.org/D7810

mmap: add a size argument to mmapread With this argument, we can control the size of the mmap created. (previously it was always the whole file. Differential Revision: https://phab.mercurial-scm.org/D7808

revlogutils: move the NodeMap class in a dedicated nodemap module We will introduce more nodemap related code, so it make sense to move the existing code in that module first. Differential Revision: https://phab.mercurial-scm.org/D7809

progress: flush stderr after clearing On python3, ui.stderr is buffered, it seems, so we need to flush it to actually get the progress bar off the screen. This is important since ui.write() will call into progbar.clear() if it thinks there's a progress bar on the screen, with the intent that the next thing it outputs is at the beginning of the line (instead of at the end of the progress bar line). Without the flush, we buffer up the clearing of the screen, and we get some really weird/corrupt output. Differential Revision: https://phab.mercurial-scm.org/D7784

rcutil: drop the `defaultrcpath()` method (API) The resource based code can service py2, py3 and an oxidized executable, so there's no reason to leave this around. It was flagged as an API change when it was introduced, so flagging it again. Differential Revision: https://phab.mercurial-scm.org/D7777

ui: add the ability to apply `defaultrc` configs from resources We will want the ability to cat out these resources, but the same would apply to templates, so I'm going to wait for the dust to settle on that. Reading the default config directly from the filesystem is still in place for now. Differential Revision: https://phab.mercurial-scm.org/D7776

ui: refactor `readconfig()` into a form that can consume resources The old form can't completely go away, because files outside of packages still need to be read. The name passed in here is a tuple of `package name, resource` as needed by the resource API. I like the idea of stating the config file is embedded in the executable by listing is as `exe!package.resource`. This would be consistent with how `debuginstall` points to the executable for the python executable, lib, and installed modules. While in practice the filesystem path is available from the backing ResourceReader when the resource is opened, it is a relative path on py2 and absolute on py3. Further, while this would show in the `hg config` output for each option if set as such here, it doesn't show in the `reading from...` line when `--debug` is used. The file isn't actually open where that prints, so there's no way I see to get that info there. So I opted for the simple prefix to distinguish resources from files.

resourceutil: implement `contents()` to iterate over resources in a package Differential Revision: https://phab.mercurial-scm.org/D7774

resourceutil: implement `is_resource()` This will be needed when iterating resources. Differential Revision: https://phab.mercurial-scm.org/D7773

resourceutil: don't limit resources to the `mercurial` package This should make things a little clearer, in that it now requires the full package name to access a resource. But the real motivation is that `extensions._disabledpaths()` walks the `hgext` directory looking for bundled extensions. This in turn feeds, among other things: 1) Listing disabled extensions in `hg help extensions` 2) Indicating that an unknown command is in a non-enabled extension 3) Displaying help for non-enabled extensions 4) Generating documentation 5) Announcing LFS is auto-enabled (or not) when cloning from an LFS source The filesystem based ResourceReader will happily return *.py and *.pyc, but the one supplied by PyOxidizer doesn't. Presumably we can change that. The only other idea I had here is for setup.py to generate a text file containing the list of extensions, but that doesn't seem great when running from source. Differential Revision: https://phab.mercurial-scm.org/D7772

setup: include `defaultrc` in the package list This is needed to access the config files via the resourceutil framework, which is needed to embed the config files when uing PyOxidizer. Differential Revision: https://phab.mercurial-scm.org/D7771

tests: update test-releasenotes-formatting.t output The output seems to be left outdated because running this test requires fuzzy-wuzzy which is not generally installed. Differential Revision: https://phab.mercurial-scm.org/D7723

tests: fix a copy/paste name duplication in storage.py Flagged by PyCharm as a redeclared name without usage, because the name matches the function immediately preceding it. But since this differs by doing regular reads instead of raw reads, I assume we still want it. But I don't see either function being called anywhere.
