There was a problem hiding this comment.
overall LGTM (nice!), but found 2 redundant defers, and left a suggestion.
don't think they're necessarily show-stoppers, but I'll let @kolyshkin have a look before merging 👍
Use t.Helper and t.Cleanup in prepareTestSet to simplify tests setup and cleanup (no need to call defer os.Remove or check error). Signed-off-by: Kir Kolyshkin <[email protected]>
In some cases, when file walk is racing with removal, the ENOENT is received by filepath.Walk[Dir], rather than by the callback. Do ignore such errors, except for the root directory (Walk argument). Modify the doc accordingly, and add a couple of test cases. The "Race" test case, when testing the code before the fix, fails 100% of times for pwalk and 90% for pwalkdir. Alas, I was unable to make it fail 100% of the times without significantly increasing the test complexity. Fixes: 199 Signed-off-by: Kir Kolyshkin <[email protected]>
