#516 chore(deps): update rust crate libc to v0.2.190 - autoclosed

v0.2.190

Compare Source

There is now a single config for enabling 64-bit time_t: libc_unstable_time64. This can be set
unconditionally; it opts in to 64-bit time_t on the following platforms that use 32-bit by
default:

• 32-bit Linux-GNU
• 32-bit Linux-uClibc
• 32-bit Linux-musl. Note that setting this flag also enables some other changes that happend in
  musl v1.2.
• 32-bit Windows-GNU
• ESP-IDF (all targets with this environment are 32-bit)

Most other 32-bit platforms are either already using 64-bit time_t, or are considered legacy
and will not be gaining support from their upstream maintainers.

You can enable this using RUSTFLAGS:

RUSTFLAGS='--cfg=libc_unstable_time64' cargo ...

Note that there may still be some changes to features gated by this config option, hence "unstable"
in its name. In the near future we will rename it to just libc_time64. Until then, please test it
out and report any bugs you find!

Removed

libc exposed quite a bit of API on all Apple platforms that is not actually available anywhere other than MacOS. This release removes a number of these cases.

• breaking Apple: Disable mach.h API on Apple mobile OSs (e6bfb187513c)
• breaking Apple: Remove a large number of items from iOS, tvOS, watchOS, and visionOS that are only available on MacOS. (#​5158)
• breaking Apple: Remove the unsupported exec* and fork calls from tvOS and watchOS (#​5158)

Additionally, this release cleans up a lot of API that has been deprecated since at least libc 0.2.100, released 2021-08-20.

• breaking Android, Linux: remove unsound af_alg_iv trait implementations. The have been deprecated for a long time because they allowed out-of-bounds reads via safe functions. (444db4456f38)
• breaking Remove most items that have been deprecated since before 0.2.100 (#​5401)

Other removed items:

• Dragonfly: Remove INHERIT_ZERO that does not exist upstream (#​5587)
• Musl riscv64: Remove GNU-gated REG_* definitions (#​5527)
• Musl riscv64: Remove non-esxistant REG_NARGS (#​5527)

A huge thank you to our GSoC student Adam Martinez (@​dybucc) who did a
huge amount of the time64 work, as well as many of the platform fixes!

v0.2.189

Compare Source

Added

• Emscripten: Add pthread_sigmask, sigwait, sigwaitinfo, sigtimedwait, faccessat, and pthread_kill (#​5270)
• Linux SPARC: Enable the clone3 syscall (#​4980)
• Solarish: Add CLOCK_PROCESS_CPUTIME_ID and CLOCK_THREAD_CPUTIME_ID (#​5274)

Deprecated

• Deprecate CLONE_INTO_CGROUP and CLONE_CLEAR_SIGHAND. These overflow their types and will be changed to a larger size in the future. (8c6e6710458d)

Fixed

• Musl riscv32: Rename padding fields to avoid a conflict and fix the build (2499ff0ad993)
• NuttX: Fix wchar_t definition under Arm (#​5245)
• Windows: Add back link names for time-related symbols (#​5300)

v0.2.188

Compare Source

Changed

• Restore Send and Sync for DIR (35b062263401)

These were removed in 0.2.187 because libc does not actually make Send and Sync
guarantees about DIR (or other extern types), but this caused some crates to break.
The traits are added back for now to allow time to migrate, but will be removed again
in the future; please make sure your crates are not relying on libc::DIR: Send or
libc::DIR: Sync.

v0.2.187

Compare Source

This release contains a number of improvements related to 64-bit time_t configuration.
Of note the existing RUST_LIBC_UNSTABLE_* environment variables have been replaced
with configuration options. The new way to use these is:

RUSTFLAGS='--cfg=libc_unstable_musl_v1_2_3' cargo ...
RUSTFLAGS='--cfg=libc_unstable_gnu_time_bits="64"' cargo ...

Being able to set this via RUSTFLAGS makes it easier to only apply configuration to
specific targets (and notably, not the host if build scripts are used).

There are two other notable changes:

• The 32-bit windows-gnu targets now respect libc_unstable_gnu_time_bits

• uClibc now supports a similar configuration option:

  RUSTFLAGS='--cfg=libc_unstable_uclibc_time64'
  

As a reminder, these options are under active development and may change in the future
(hence the "unstable" in the name). It likely that we will harmonize everything under a
single configuration option before considering them stable.
