Raise MSRV to 1.40.0
2020-12-14Ignore failures of test_aio_suspend on macosAlan Somers
On Cirrus-CI, this test frequently fails with EINVAL. The error goes away if I add a line of debugging, so it's probably a timing issue. But I can't debug it myself. Issue #1361
2020-12-10Remove a workaround for an old Musl bugAlan Somers
In older versions of Musl, ttyname_r would wrongly return ENOTTY instead of EBADF. We expected that bug in our test suite. But Rust 1.37.0 updated Musl to 1.1.22, which fixes the problem. This change reverts our workaround. https://www.openwall.com/lists/musl/2018/09/15/2 https://github.com/rust-lang/rust/commit/aaf66987931dfe06a547b9f68cb709e9b6265b5c

Fix intermittency in the doc test for alarm
2020-12-09Fix intermittency in the doc test for alarmAlan Somers
On Cirrus CI, this test would sometimes fail, probably due to pause being awoken by SIGRT_1. sigwait is a superior alternative to pause. Fixes #1354

Fix intermittency in some tests
2020-12-09Ignore the execve tests on muslAlan Somers
On Cirrus-CI, these tests frequently segfault. It's probably indicative of a real bug, not just a problem in the tests. But for now we need to skip them to get CI working. Issue #555
2020-12-08Fix unreliability in sys::test_aio::test_aio_suspendAlan Somers
On OSX, this test has begun to fail in CI on OSX. Presumably it's because aio_suspend was getting interrupted by a signal.
2020-12-08Fix a race in the test_unistd::test_fchown testAlan Somers
The test was assuming that once dropped, a temporary file's file descriptor would be invalid. But it might not be, because another file might be opened with the same file descriptor. Instead, use an obviously invalid file descriptor.

Switch all builds from Travis to Cirrus
2020-12-07Fix a use-after-free in execve_test_factoryAlan Somers
Ensure that the exec functions' arguments are valid for 'static. Previously they were short-lived temporaries.
2020-12-06Switch all builds from Travis to CirrusAlan Somers
Travis has been super-slow lately (> 6 hours per build). Cirrus is much faster: about 20 minutes. Cirrus also has slightly better test coverage, mainly because it doesn't use SECCOMP. Also, * Fix the Redox CI build. The old Travis configuration didn't actually build for Redox, so we never noticed that Redox can't be built with a stable compiler. Thanks to @coolreader18 for finding this. * Disable the udp_offload tests on cross-tested platforms. These tests are failing with ENOPROTOOPT in Cirrus-CI. I suspect it's due to a lack of support in QEMU. These tests were skipped on Travis because its kernel was too old. * Fix require_kernel_version on Cirrus-CI. Cirrus reports the Linux kernel version as 4.19.112+, which the semver crate can't handle. * Fix test_setfsuid on Cirrus. When run on Cirrus, it seems like the file in /tmp gets deleted as soon as it's closed. Probably an overzealous temporary file cleaner. Use /var/tmp, because no temporary file cleaner should run in there. * Skip mount tests on Cirrus. They fail for an unknown reason. Issue #1351 * Skip the AF_ALG tests on Cirrus-CI Issue #1352

When run in Cirrus-CI's environment, the tests generate copious SIGRT_1 signals. This commit ensures that test_alarm will ignore them.

1345: Disable test-aio-drop in GNU environments r=asomers a=asomers This test occasionally fails in Travis on x86_64-unknown-linux-gnu. The failure takes the form of the test executable receiving a random signal. Sometimes SIGHUP, sometimes SIGKILL, etc. I think this must be a bug in glibc, even though I can't reproduce it in my development environment. But it interferes with CI too much to leave enabled.

1341: Fix recvmmsg(2) implementation r=asomers a=codeslinger There were two problems discovered with the `recvmmsg(2)` implementation that this changeset attempts to fix: 1. As mentioned in nix-rust/issues/1325, `recvmmsg(2)` can return fewer messages than requested, and 2. Passing the return value of `recvmmsg(2)` as the number of bytes in the messages received is incorrect. This changeset incorporates the proposed fix from nix-rust/issues/1325, as well as passing the correct value (`mmsghdr.msg_len`) for the number of bytes in a given message.

1318: KEEPCNT/KEEPINTVL aren't available on OpenBSD. r=asomers a=ltratt Without this commit, nix doesn't currently compile on OpenBSD. Some keepalive settings can be set globally, but not per-socket (see e.g. https://bugzilla.mozilla.org/show_bug.cgi?id=970550 for some digging into this). Since it seems that NetBSD and DragonflyBSD have these settings, it makes more sense to only exclude them on OpenBSD rather than include them on (pretty much every) other operating systems.
