Release Notes

rust-lang/libc (libc)

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.

v0.2.184

MSRV

This release increases the MSRV of libc to 1.65. With this update, you can now always use the
core::ffi::c_* types with libc definitions, since libc has been changed to reexport from
core rather than redefining them. (This usually worked before but had edge cases.)

v0.2.179

Compare Source

With this release, we now have unstable support for 64-bit time_t on 32-bit
platforms with both Musl and Glibc. Testing is appreciated!

For now, these can be enabled by setting environment variables during build:

RUST_LIBC_UNSTABLE_MUSL_V1_2_3=1
RUST_LIBC_UNSTABLE_GNU_TIME_BITS=64

Note that the exact configuration will change in the future. Setting the
MUSL_V1_2_3 variable also enables some newer API unrelated to time_t.
