The test was added in dc34990, it turns out that it's flaky. It failed once on the Debian build infra, cf. [1]. The problem is that the command `rsync -aH '$fromdir/sym' '$todir'` updates the mod time of `$todir`, so there might be a diff between the output of `rsync_ls_lR $fromdir` and `rsync_ls_lR $todir`, if ever rsync runs 1 second (or more) after the directories were created. To clarify: it's easy to make the test fails 100% of the times with this change: ``` makepath "$fromdir/sym" "$todir" +sleep 5 checkit "$RSYNC -aH '$fromdir/sym' '$todir'" "$fromdir" "$todir" ``` The fix proposed here is in line with other tests in hardlinks.test, as far as I can see all the tests use a trailing slash for the `$fromdir` and `$todir` arguments. I tested that, after this commit, the test still catches the regression in rsync 3.4.0. Fixes: RsyncProject#735 [1]: https://buildd.debian.org/status/fetch.php?pkg=rsync&arch=ppc64el&ver=3.4.1%2Bds1-1&stamp=1741147156&raw=0

Actually this approach doesn't work, it doesn't catch the -H regression in rsync-3.4.0 anymore... Closing in favor of #737. |
