py3: pass a bytes value for "msg" to nouideprecwarn() That function formats "msg" with the "version" value. On Python 3, this leads to "TypeError: can only concatenate str (not "bytes") to str". Also eliminate spurious strings concatenation in single-line declarations. Differential Revision: https://phab.mercurial-scm.org/D7373

remotefilelog: handle **kwargs correctly when overriding changelog.add() Differential Revision: https://phab.mercurial-scm.org/D7372

packaging: ship all help .txt files on WiX These are technically not needed. But it is easier to ship all files than to cherry-pick. A `make install` will copy these files, so the new behavior is consistent with that. This also makes WiX consistent with Inno, which is my main reason for doing this. If we don't want to ship the files (which is a valid argument), I think we can do that in a follow up. Differential Revision: https://phab.mercurial-scm.org/D7166

packaging: install contrib/mq.el on WiX This makes things consistent with the Inno installer. Differential Revision: https://phab.mercurial-scm.org/D7167

fuzz: clean out most of fuzzutil It's now a header-only setup that just selects absl:: or std:: versions of things as needed, and a logging helper. There's some room for future cleanups here: we could move to just requiring a C++17 compiler and get rid of the absl stuff. Also, the mpatch parser has a fair amount of parsing the input string into char* blocks that we can and probably should fix that up to use FuzzedDataProvider as well.

dirstate: re-blacken file This got overlooked in landing a recent patch, but it's easy to fix up. Differential Revision: https://phab.mercurial-scm.org/D7367

rust-matchers: remove default implementations for `Matcher` trait We don't expect a whole lot of matchers to be defined, and this makes it more obvious what a matcher does by reading its `impl Matcher for FooMatcher`. This patch has the added benefit of fixing the `AlwaysMatcher`, its `matches` function differs from the former default. Differential Revision: https://phab.mercurial-scm.org/D7255

packaging: use lower case for RC files The file case doesn't matter. I'm not sure why it is capitalized. This is a source of inconsistency between Inno and WiX. So let's standardize on the lower case names. The MSI should remove the old files before installing the new one, so there shouldn't be a problem with a case collision. And, users should not have modified these files, so it should be safe to rename them. Differential Revision: https://phab.mercurial-scm.org/D7172

packaging: write out editor.rc in Python Let's dynamically generate the file from Python instead of relying on Inno functionality, as that will give more visibility into what's going on. I spotted this as part of converging the install layout of Inno and WiX: the former doesn't install an editor.rc and instead defines the editor via its mercurial.rc file. We will change the behavior of WiX later once it is consuming the staged install directory for packaging. Differential Revision: https://phab.mercurial-scm.org/D7171

packaging: stop installing Contributors.txt This file isn't up to date. If we are going to call out contributors, we should auto generate a file from `hg log` or something. I don't think we need to include it in the Windows install. This change makes Inno more consistent with WiX, which doesn't ship this file. Differential Revision: https://phab.mercurial-scm.org/D7170

packaging: remove hg-ssh.8.html from Inno installer We don't ship hg-ssh because it requires a python.exe to run, which we don't ship. So it doesn't make sense to ship the HTML documentation for this tool. This change makes the Inno install layout more consistent with WiX, which doesn't ship this file. Functionality for removing files has been made generic, in anticipation of future expansion. Differential Revision: https://phab.mercurial-scm.org/D7169

packaging: install .rc files to hgrc.d Currently, Inno installs these .rc files to a default.d directory and WiX to a hgrc.d directory. Mercurial automatically loads files in an hgrc.d directory next to the executable and in an "internal" default.d directory. This "internal" directory is util.datadir, which on Windows installs made with py2exe is the directory containing hg.exe. So on Windows both hgrc.d and default.d directories relative to hg.exe are loaded. For the install layout, I think it makes sense for hgrc.d to be used, as that path is documented as non-internal. So this commit changes the Inno install layout to use hgrc.d instead of default.d. .. bc:: Changed default config file location in Windows .exe installers Mercurial's installer installs some default .rc config files. Previously, these were installed in a default.d directory. These are now installed in an hgrc.d directory. Custom default.d/*.rc files should still be loaded. But it is recommended to move these to hgrc.d/*.rc. This change only affects the .exe installers (not the .msi installers). Differential Revision: https://phab.mercurial-scm.org/D7168

rust: introduce SIZE_FROM_OTHER_PARENT constant This will clarify what `-2` meant in the codebase. This change also merged imports in affected files for cleanup. Differential Revision: https://phab.mercurial-scm.org/D7301

rust-status: refactor dispatch case for normal files This should make the code easier to read and more idiomatic. Differential Revision: https://phab.mercurial-scm.org/D7300

rust-status: return a ParallelIterator instead of a Vec from stat_dmap_entries This allows the caller function to choose when and how the iteration and/or collection happens. This change also cleans up the now unused `filter_map`. Differential Revision: https://phab.mercurial-scm.org/D7299

rust-status: improve status performance This change does more things in the parallel loop, refactors the file-level logic into two functions for added clarity. This bit of Rust code takes 55ms to execute on a repo where the stat'ing part of Valentin's fast path takes 40ms. While the code differs a bit and it's hard to get an exact measurement of how much of a performance impact it has, I can be fairly certain that this implementation is *at worse* twice as slow.

bookmarks: accept explicit -r 'wdir()' when adding new bookmarks (issue6218) Even though the bookmark semantics can't be fully encoded to the virtual working changeset idea, the active bookmark can be considered a bookmark of the working revision. Before, 'tgt' was None, and changes=[(bm, None)] means deleting a bookmark named 'bm'.

bookmarks: use changectx instead of remembering hex of hidden revision It should be better to not depend on the ctx variable which was assigned conditionally.

bookmarks: resolve target revision out of the bookmarks loop The target revision doesn't depend on the bookmark to be added.

bookmarks: fix handling of multiple bookmarks with one to be deactivated Before, "hg bookmark --inactive Z Y" would ignore "Y" if "Z" were currently active. I'm pretty sure it is a bug.

import-checker: allow 'from typing import ...' Suppresses the following error in test-check-module-imports.t: mercurial/encoding.py:24: relative import of stdlib module
