Bug 1386857 - [ci] Remove the 'tc' treeherder group prefix from all tasks, r=dustin There are now only a handful of buildbot jobs remaining and the concern over outdated treeherder exclusion profiles has largely been resolved. This does remove the tc() group from a substantial number of tasks which will now show up as top level tasks, potentially adding clutter. In some cases, we might want to re-add a new group (e.g group builds or compiled tests together). However rather than try to predict the best group names for tasks I'm unfamiliar with, I think it's best to land this as is. Then if things are looking too cluttered at the root namespace, file follow-up bugs as needed. MozReview-Commit-ID: 8SMwjDwAOzV

Bug 1386857 - [taskgraph] Add path of offending config file to the UNKNOWN_GROUP_NAME error message, r=dustin When trying to remove an ubiquitous group like tc(), it's hard to tell where the error was located without grepping my filesystem. This makes it a bit easier to find and fix these errors. MozReview-Commit-ID: 8NjvB5zOoqb

Bug 1431226 - Reference proper function and allow loading hgrc; r=nalexander This fixes a regression in 195e88aab631 (bug 1429094). When I reviewed that changeset, I didn't realize there were callers of the renamed function outside the file. The other caller (changed in this commit) needs to interact with the repository. This may require loading extensions. So we can no longer unconditionally disable the loading of hgrc. We add an argument to control the loading of hgrc to support this.

Bug 1403519 - only build docs when necessary r=gps This marks **/docs/** as exclusively docs, and code that is autodoc'd as inclusively docs. That means that a change that purely modifies documentation files will *only* run `docs` tasks, while a change that modifies autodoc'd source code will *additionaly* run `docs` tasks. The tasks do not run by default. MozReview-Commit-ID: G9tOK0AwtrI

Bug 1430886 - Disable incremental rust in automation. r=froydnj Work around excessive command-line length issues by disabling incremental rust compilation, which is enabled by default outside `cargo --release` starting with Rust 1.24. Incremental rust builds shouldn't help much in automation, where sccache provides the only continuity between build environments. In the meantime, they add a lot of object files to the link line. See https://github.com/rust-lang/rust/pull/47507 about addressing the underlying issue upstream. MozReview-Commit-ID: LRwUj3fhiaO

Bug 1429846: Fix slotted invalidation. r=heycam This is a partial revert of https://github.com/servo/servo/commit/ce1d8cd232dfbc9e0a52f9467ba2bc209087ea63 If you're in a shadow tree, you may not be slotted but you still need to look at the slotted rules, since a <slot> could be a descendant of yours. Just use the same invalidation map everywhere, and remove complexity. This means that we can do some extra work while trying to gather invalidation if there are slotted rules, but I don't think it's a problem. The test is ported from https://cs.chromium.org/chromium/src/third_party/WebKit/LayoutTests/fast/css/invalidation/slotted.html?l=1&rcl=58d68fdf783d7edde1c82a642e037464861f2787 Curiously, Blink fails the test as written, presumably because they don't flush styles from getComputedStyle correctly (in their test they do via updateStyleAndReturnAffectedElementCount), due to <slot>s not being in the flat tree in their implementation.

bug 1419756 - deactivate pytest cache plugin to stop it writing files in the srcdir. r=davehunt The pytest cache plugin writes its cache in the srcdir, which means that it shows up in `hg status`, which is annoying. Writing files to the srcdir is generally bad practice anyway, so we disable this plugin to stop this from happening. MozReview-Commit-ID: HytLLMUtKlc
