Smith <psmith@gnu.org> + * test_driver.pl (touch): Rewrite this function. Previously it + used to use utime() to hard-set the time based on the current + local clock. This fails badly on networked filesystems where the + FS server clock is skewed from the local clock: normally modifying + a file causes it to get a mod time based on the _server's_ clock. + Hard-setting it based on the _local_ clock causes gratuitous + errors and makes the tests unreliable except on local filesystems. + The new function will simply modify the file, allowing the + filesystem to set the mod time as it sees fit. + * scripts/features/parallelism: The second test output could change depending on how fast some scripts completed; use "sleep" to force the order we want. diff --git a/tests/test_driver.pl b/tests/test_driver.pl index 7dd7fda..001d247 100644 --- a/tests/test_driver.pl +++ b/tests/test_driver.pl @@ -785,19 +785,40 @@ sub remove_directory_tree_inner return 1; } +# We used to use this behavior for this function: +# +#sub touch +#{ +# local (@filenames) = @_; +# local ($now) = time; +# local ($file); +# +# foreach $file (@filenames) +# { +# utime ($now, $now, $file) +# || (open (TOUCHFD, ">> $file") && close (TOUCHFD)) +# || &error ("Couldn't touch $file: $!\n", 1); +# } +# return 1; +#} +# +# But this behaves badly on networked filesystems where the time is +# skewed, because it sets the time of the file based on the _local_ +# host.
