rust-dirstatemap: don't read the dirstate when requesting parents A future patch for issue 6303 reveals a big performance regression in the Rust `DirstateMap` that reads the entire dirstate when requesting parents instead of the first 40 bytes. `perfdiscovery` gets a *significant* speedup (from 0.101 to 0.016) when applied against said patch. I'm assuming it has other performance benefits, but this is already a good enough win. Differential Revision: https://phab.mercurial-scm.org/D8513

py3: fix exception in pull when several things happen to a bookmark Specifically, when `changes` is: [(b'@upstream-committed', None, <function ui.status>, b'updating bookmark @upstream-committed\n'), (b'@upstream-committed', binary-node, <function ui.warn>, b'divergent bookmark @ stored as @upstream-committed\n')] sorting the list raises: TypeError: '<' not supported between instances of 'bytes' and 'NoneType' Differential Revision: https://phab.mercurial-scm.org/D8523

cleanup: avoid extra node/ctx conversions in logcmdutil.diffordiffstat I'm about to write some code that wants to pass a memctx to diffordiffstat, but this feels like a meritorious cleanup anyway, since the first thing this method does is turn nodes into contexts, and most callers have a context handy.

pyoxidizer: formatting bazel definitions This meets the Bazel style guide: https://docs.bazel.build/versions/master/skylark/bzl-style.html and was mostly done automatically with buildifier. Differential Revision: https://phab.mercurial-scm.org/D8521

fastexport: adjust output to be more canonical For time zones, git doesn't consider +0 and -0 the same timezone, so use the former canonically. Add a test case to ensure that non-UTC offsets are handled correctly. The real name part of the committer name is normally not quoted, so don't enforce that.

bash_completion: do not use aliased hg if it sources a script (issue6308) I have an alias that sources a script around hg. Mercurial's bash_completion script tries to use this as its main hg binary. But sourcing a wrapper breaks Bash's completion. So this patch disables using the alias as the hg binary if it starts with "source ". Alias resolution was introduced in rev 191ab08e7099 for users with "alias hg='hg --some_opts'". See https://www.mercurial-scm.org/repo/hg/rev/191ab08e7099
