fs: Run file lock tests on all platforms that support it by tgross35 · Pull Request #149111 · rust-lang/rust

tgross35 · 2025-11-19T20:44:14Z

There are a number of platforms that support file locking but aren't getting tested. Synchronize the list and mark the tests should_panic otherwise, to make sure they get updated if more platforms add locking support.

The supported platform list comes from

rust/library/std/src/sys/fs/unix.rs

Lines 1291 to 1308 in 07bdbae

#[cfg(any(
 target_os = "freebsd",
 target_os = "fuchsia",
 target_os = "linux",
 target_os = "netbsd",
 target_os = "openbsd",
 target_os = "cygwin",
 target_os = "illumos",
 target_os = "aix",
 target_vendor = "apple",
))]
pubfnlock(&self) -> io::Result<()>{
cvt(unsafe{ libc::flock(self.as_raw_fd(), libc::LOCK_EX)})?;
returnOk(());
}
#[cfg(target_os = "solaris")]
pubfnlock(&self) -> io::Result<()>{

. Windows also supports file locks, all other platforms are unsupported.

The list of platforms for which file locks are tested is smaller than the list of platforms that support it. Synchronize these here. Link: https://github.com/rust-lang/rust/blob/07bdbaedc63094281483c40a88a1a8f2f8ffadc5/library/std/src/sys/fs/unix.rs#L1291-L1308

Sorry bors3

@bors2 try jobs=arm-android,test-various

rust-bors · 2025-11-19T22:19:18Z

💔 Test for 534bfac failed: CI. Failed jobs:

try - arm-android (web logs, extended logs)

Rather than skipping the tests, make sure that they fail. This ensures that if file locking support is added for more platforms in the future, the tests don't wind up quietly skipped.

FYI, you no longer need to call bors2 because bors try already uses the new one: https://rust-lang.zulipchat.com/#narrow/channel/131828-t-compiler/topic/Testing.20try.20builds.20with.20new.20bors/near/530101996

Thanks! I know it works now, just something that I ingrained pretty hard after having caused a try->r+ shootthrough to master a while back.

ChrisDenton · 2025-11-20T13:42:56Z

I'm slightly nervous that something will break on full CI but let's find out...
