Fix these: inotify_test.go:134:7: S1005: unnecessary assignment to the blank identifier (gosimple) case _ = <-w.Events: ^ inotify_test.go:351:2: S1005: unnecessary assignment to the blank identifier (gosimple) _ = <-w.Events // consume Remove event ^ Signed-off-by: Kir Kolyshkin <[email protected]>
The staticcheck linter suggests: inotify_test.go:146:2: SA5001: should check returned error before deferring w.Close() (staticcheck) defer w.Close() ^ Instead, remove the defer entirely because we have one already earlier in the code. Signed-off-by: Kir Kolyshkin <[email protected]>
The staticcheck linter warns:
inotify_poller.go:122:5: SA9003: empty branch (staticcheck)
if event.Events&unix.EPOLLHUP != 0 {
^
Commit 8165837 removed the code that handles this case,
so it is no longer needed. The comment would be nice to have, but it
is sort of obvious.

Check for and return an error in case w.poller.wake() failed, to fix this warning: inotify.go:83:15: Error return value of `w.poller.wake` is not checked (errcheck) w.poller.wake() ^ Signed-off-by: Kir Kolyshkin <[email protected]>
1. Add t.Helper() call to newWatcher() and addWatch() helper functions for tests to show proper file/line information on errors. 2. Fix addWatch argument name and docstring since it is not always a directory. 3. Use newWatcher and addWatch where possible, fixing a few cases of missing error checks. 4. Fix a case where os.Create() result is not checked, and the resulting file is not closed. 5. Some related refactoring. Signed-off-by: Kir Kolyshkin <[email protected]>
1. Fix two cases where the test tries to write to a file which was opened read-only. 2. Add and use helper functions ok() and writeData() to aid in tests error checking. Signed-off-by: Kir Kolyshkin <[email protected]>
At the moment there should be none. Signed-off-by: Kir Kolyshkin <[email protected]>

I'm not entirely sure if this is really the correct behaviour; I think that this failing isn't really a big deal in the Close() here?

The comment says it "should wake up", but it doesn't do anything. I'm not sure if this can just be removed, or if there's an omission here and we should put something in this branch.

Should be fixed in the main branch now. |
