node: manually implement Debug I got too irritated today with the default Debug implementation of hg::revlog::Node while playing with a new parser. This isn't quite what I wanted, but it wasn't much code and it at least gives you output that's easy to visually compare to a node.hex()ed identifier from the Python side of things. Sadly, this doesn't influence the output in lldb or the VSCode debugger extension that uses lldb under the covers, but it at least means debug prints are a little more useful.

censor: make rhg fall back to python when encountering a censored node This is to make it support censor.policy=ignore without having to duplicate that logic. Also, change the censor test in such a way that it uses rhg now, because extensions are disabled except when we call [hg censor]. Differential Revision: https://phab.mercurial-scm.org/D12607

contrib: migrate off of a couple of bitbucket URLs I noticed this when diffing the thg installer against Mercurial to see what was missing. There are a handful of other URLs in i18n and extension example help text if anyone cares to update those. Differential Revision: https://phab.mercurial-scm.org/D12606

followlines: don't put Unicode directly into the .js file (issue6559) Apparently some web server setups may serve this file in a different encoding than UTF-8, and that results in visual garbage in the followlines button that renders for every line in a file. So instead of using this Unicode character in UTF-8 we can encode it as \u2212. Or, to be more explicit, we can use − HTML entity, which resolves into exactly that character. Since now we're using innerHTML property to set the minus part of the button, let's use it to set the plus part as well (even though the plus sign was plain ASCII). A wise man once said "A foolish consistency is the hobgob... eh, whatever." Throw a brick at me if this makes things worse. Differential Revision: https://phab.mercurial-scm.org/D12597

wix: bump the minimum Windows required to 8.1 PyOxidizer binaries are built with py 3.9.6, so not even Windows 7 is supported. Unfortunately, there don't appear to be more recent values for newer versions of Windows, but at least Windows 8.1 is still in extended support for another 9 months or so.

filemerge: add configs to disable some or all partial merge tools When rolling out partial merge tools to users, it's useful to be able to easily turn one or all of them off if a problem is discovered. This patch adds support for that. They can of course also be useful for individual users to be able to temporarily turn off a tool they are otherwise using.

branching: merge stable into default

branching: merge stable into default This also added the small fix need in Rust tests for the new `DirstateMap::pack_v2` API change in stable.

rust-dirstatemap: add simpler version of `get_node_mut` This will help reduce code and footgun potential for simpler callers. Differential Revision: https://phab.mercurial-scm.org/D12531

rust-dirstatemap: use `get_node_mut` instead or `get_or_insert_node` This (along with the docstring), makes it more obvious that we're not expecting to insert a node here. This is less prone to bugs in later refactorings. Differential Revision: https://phab.mercurial-scm.org/D12530

rust-dirstatemap: add `each_ancestor` argument to `get_node_mut` This forces the callers to think about if the counters in the ancestors need to be adjusted. Differential Revision: https://phab.mercurial-scm.org/D12529

rust-dirstatemap: add simpler method `get_or_insert_node` for the common case All but one case use the exact same input for most arguments, this simplifies code and reduces footgun potential. Differential Revision: https://phab.mercurial-scm.org/D12528

rust-dirstatemap: inline the last `get_or_insert` call The `get_or_insert` method was dangerous because it did not take the `DirstateMap` counters into account. This particular instance does not need to update the counters. Differential Revision: https://phab.mercurial-scm.org/D12527

rust-dirstatemap: add `set_cached_mtime` helper method This will help remove the `get_or_insert` method, which is dangerous because it does not take the `DirstateMap` counters into account Differential Revision: https://phab.mercurial-scm.org/D12526

rust-dirstatemap: add `clear_cached_mtime` helper method This will help remove the `get_or_insert` method, which is dangerous because it does not take the `DirstateMap` counters into account. Differential Revision: https://phab.mercurial-scm.org/D12525

rust-dirstatemap: add unit tests These were missing and have already proven valuable since they have found two bugs (fixed in previous patches). There may be other behavior to test, but this gives us a decent coverage. Differential Revision: https://phab.mercurial-scm.org/D12524
