Update dist-various to Ubuntu 20.04 #81521

nikic · 2021-01-29T17:39:14Z

This updates the dist-various-1 and dist-various-2 images to Ubuntu
20.04. This requires some adjustments:

DEBIAN_FRONTEND=noninteractive required for apt install.
team-gcc-argm-embedded PPA does not support focal. However,
we can simply use the distro-provided gcc-arm-none-eabi. Per
the comment, the PPA was only used to get a newer version.
rumprun has to be updated to avoid a linker error.
We need to build rumrun with NOGCCERROR, which disables use
of -Werror and allows building with a newer compiler.
We need to install libtinfo5, which appears to be a dependency
of the clang used during the fuchsia build.
We need to switch to g++-8 rather than g++-7, as at least
g++-7-arm-linux-gnueabi is not available on focal.
We need to upgrade to GCC 6.5 for the Solaris build, as GCC 6.4
does not support the newer libisl version.

I'm a little concerned that this will raise the glibc symbol versions of the *linux-gnu* targets, although this set doesn't include any that I personally need. None of these are hosts though, so I guess it will only affect use of -Cprefer-dynamic on the standard library.

Mark-Simulacrum · 2021-01-30T00:43:29Z

Yeah, and I think for dist various we've not tried to be as strict with that version, so I'm not too worried. We should mark as relnotes though.

Pkgsrc changes: * Remove one SunOS patch, apparently no longer needed. * Adapt one patch for Darwin, adjust cargo checksum accordingly. * Adjust bootstraps to version 1.50.0.

See the [Cargo book documentation][feature-resolver@2.0] for more information on the feature. Rustdoc ------- - [Rustdoc will now include documentation for methods available from `Deref` traits.][80653] - [You can now provide a `--default-theme` flag which sets the default theme to use for documentation.][79642] Various improvements to intra-doc links: - [You can link to non-path primitives such as `slice`.][80181] - [You can link to associated items.][74489] - [You can now include generic parameters when linking to items, like `Vec<T>`.][76934] Misc ---- - [You can now pass `--include-ignored` to tests (e.g. with `cargo test -- --include-ignored`) to include testing tests marked `#[ignore]`.][80053] Compatibility Notes ------------------- - [WASI platforms no longer use the `wasm-bindgen` ABI, and instead use the wasm32 ABI.][79998] - [`rustc` no longer promotes division, modulo and indexing operations to `const` that could fail.][80579] - [The minimum version of glibc for the following platforms has been bumped to version 2.31 for the distributed artifacts.][81521] - `armv5te-unknown-linux-gnueabi` - `sparc64-unknown-linux-gnu` - `thumbv7neon-unknown-linux-gnueabihf` - `armv7-unknown-linux-gnueabi` - `x86_64-unknown-linux-gnux32` Internal Only ------------- - [Consistently avoid constructing optimized MIR when not doing codegen][80718] [79135]: rust-lang/rust#79135 [74489]: rust-lang/rust#74489 [76934]: rust-lang/rust#76934 [79570]: rust-lang/rust#79570 [80181]: rust-lang/rust#80181 [79642]: rust-lang/rust#79642 [80945]: rust-lang/rust#80945 [80279]: rust-lang/rust#80279 [80053]: rust-lang/rust#80053 [79502]: rust-lang/rust#79502 [75180]: rust-lang/rust#75180 [79135]: rust-lang/rust#79135 [81521]: rust-lang/rust#81521 [80968]: rust-lang/rust#80968 [80959]: rust-lang/rust#80959 [80718]: rust-lang/rust#80718 [80653]: rust-lang/rust#80653 [80579]: rust-lang/rust#80579 [79998]: rust-lang/rust#79998 [78044]: rust-lang/rust#78044 [81455]: rust-lang/rust#81455 [80764]: rust-lang/rust#80764 [80749]: rust-lang/rust#80749 [80662]: rust-lang/rust#80662 [77885]: rust-lang/rust#77885 [cargo/8997]: rust-lang/cargo#8997 [cargo/9112]: rust-lang/cargo#9112 [feature-resolver@2.0]: https://doc.rust-lang.org/nightly/cargo/reference/features.html#feature-resolver-version-2 [`Once::call_once_force`]: https://doc.rust-lang.org/stable/std/sync/struct.Once.html#method.call_once_force [`sync::OnceState`]: https://doc.rust-lang.org/stable/std/sync/struct.OnceState.html [`panic::panic_any`]: https://doc.rust-lang.org/stable/std/panic/fn.panic_any.html [`slice::strip_prefix`]: https://doc.rust-lang.org/stable/std/primitive.slice.html#method.strip_prefix [`slice::strip_suffix`]: https://doc.rust-lang.org/stable/std/primitive.slice.html#method.strip_prefix [`Arc::increment_strong_count`]: https://doc.rust-lang.org/nightly/std/sync/struct.Arc.html#method.increment_strong_count [`Arc::decrement_strong_count`]: https://doc.rust-lang.org/nightly/std/sync/struct.Arc.html#method.decrement_strong_count [`slice::fill_with`]: https://doc.rust-lang.org/nightly/std/primitive.slice.html#method.fill_with [`ptr::addr_of!`]: https://doc.rust-lang.org/nightly/std/ptr/macro.addr_of.html [`ptr::addr_of_mut!`]: https://doc.rust-lang.org/nightly/std/ptr/macro.addr_of_mut.html [`array::IntoIter`]: https://doc.rust-lang.org/nightly/std/array/struct.IntoIter.html [`slice::split_inclusive`]: https://doc.rust-lang.org/nightly/std/primitive.slice.html#method.split_inclusive [`slice::split_inclusive_mut`]: https://doc.rust-lang.org/nightly/std/primitive.slice.html#method.split_inclusive_mut [`str::split_inclusive`]: https://doc.rust-lang.org/nightly/std/primitive.str.html#method.split_inclusive [`task::Wake`]: https://doc.rust-lang.org/nightly/std/task/trait.Wake.html [`Seek::stream_position`]: https://doc.rust-lang.org/nightly/std/io/trait.Seek.html#method.stream_position [`Peekable::next_if`]: https://doc.rust-lang.org/nightly/std/iter/struct.Peekable.html#method.next_if [`Peekable::next_if_eq`]: https://doc.rust-lang.org/nightly/std/iter/struct.Peekable.html#method.next_if_eq

Pkgsrc changes: * Add support for the big-endian arm64 NetBSD target (aarch64_be). * On NetBSD/i386, use the i586 (pentium) bootstrap kit variant in preference to i686. * Adjust patches, re-compute line offsets, re-compute crate checksums. * Remove a patch which was either integrated upstream and/or no longer applies. * Bump bootstraps to 1.50.0. * Move conditionals until after bsd.prefs.mk so that they work... * Default to "dist" build target if cross-compiling, but allow also to override via rust.BUILD_TARGET. * Allow overriding MAKE_JOBS_SAFE via rust.MAKE_JOBS_SAFE if you want a different trade-off between occasional breakage and performance. * Adjust platform.mk according to work already done in wip/rust/ * Add a patch to optimize the install.sh script used to install binary bootstraps to not do so many forks; use case/esac and parameter expansion instead of grep, sed and cut. * Drop building documentation for the binary bootstrap kits. This will also impact the lang/rust-bin package. For full documentation, build or install lang/rust as a package.

These Tier 2 non-host targets were affected by the update to `ubuntu:22.04` in rust-lang#113931, but the platform support page was already out of date after rust-lang#81521 updated to `ubuntu:20.04`. They are now listed for kernel 5.15 and glibc 2.35 as found in 22.04, and a new footnote mentions that this only matters when using the dynamic `libstd.so`.
