2025-04-30os: test overlapped pipes deadlines on Windowsqmuntal
NewFile recently added support for overlapped I/O on Windows, which allows us to set deadlines on them, but the test coverage for this new feature is not exhaustive. Modify the existing pipe deadline tests to also exercise named overlapped pipes. Updates #19098.

- Use testenv.Command instead of exec.Command to try to get more useful timeout behavior. - Parallelize tests that appear not to require global state. (And add explanatory comments for a few that are not parallelizable for subtle reasons.) - Consolidate some “Helper” tests with their parent tests. - Use t.TempDir instead of os.MkdirTemp when appropriate. - Factor out subtests for repeated test helpers.

2022-06-30os: simplify deadline fluctuation testsIan Lance Taylor
This applies the net package CL 365334, CL 366176, CL 372215 to the os package. CL 365334: These tests were checking for fairly narrow timing windows, but were running in parallel and heavily dependent on timer and goroutine scheduling. This change eliminates unnecessary goroutines, runs the tests sequentially (dramatically shortening the timeouts to reduce the penalty of doing so), and uses timestamp comparison instead of background timers to hopefully gain some robustness from monotonic timestamps. Many of the other tests from this package would benefit from similar simplifications, which we can apply if and when we notice flaky failures or want to improve the latency of running the test. CL 366176: It appears that at least the OpenBSD kernel gets sloppier the longer the timeout we give it, up to an observed overhead of around 25%. Let's give it a little more than that (33%) in the comparison, and also increase the growth curve to match the actual observed times instead of exponential initial growth. CL 372215: Decrease the slop everywhere else, since NetBSD and OpenBSD seem to be the only ones that miss by that much. For #36108 For #50189 Fixes #50725 (we hope) Change-Id: I0854d27af67ca9fcf0f9d9e4ff67acff4c2effc8 Reviewed-on: https://go-review.googlesource.com/c/go/+/415234 Run-TryBot: Ian Lance Taylor <iant@golang.org> Reviewed-by: Bryan Mills <bcmills@google.com> Reviewed-by: Ian Lance Taylor <iant@google.com>
2021-10-28all: go fix -fix=buildtag std cmd (except for bootstrap deps, vendor)Russ Cox
When these packages are released as part of Go 1.18, Go 1.16 will no longer be supported, so we can remove the +build tags in these files. Ran go fix -fix=buildtag std cmd and then reverted the bootstrapDirs as defined in src/cmd/dist/buildtool.go, which need to continue to build with Go 1.4 for now. Also reverted src/vendor and src/cmd/vendor, which will need to be updated in their own repos first. Manual changes in runtime/pprof/mprof_test.go to adjust line numbers. For #41184.

As part of #42026, these helpers from io/ioutil were moved to os. (ioutil.TempFile and TempDir became os.CreateTemp and MkdirTemp.) Update the Go tree to use the preferred names. As usual, code compiled with the Go 1.4 bootstrap toolchain and code vendored from other sources is excluded. ReadDir changes are in a separate CL, because they are not a simple search and replace.

2020-04-25os, net: define and use os.ErrDeadlineExceededIan Lance Taylor
If an I/O operation fails because a deadline was exceeded, return os.ErrDeadlineExceeded. We used to return poll.ErrTimeout, an internal error, and told users to check the Timeout method. However, there are other errors with a Timeout method that returns true, notably syscall.ETIMEDOUT which is returned for a keep-alive timeout. Checking errors.Is(err, os.ErrDeadlineExceeded) should permit code to reliably tell why it failed. This change does not affect the handling of net.Dialer.Deadline, nor does it change the handling of net.DialContext when the context deadline is exceeded. Those cases continue to return an error reported as "i/o timeout" for which Timeout is true, but that error is not os.ErrDeadlineExceeded.
