Dmitry described his view on the matter:
"The test checks, in particular, whether "strace -c" shows a reasonable value in "seconds" column, by invoking nanosleep with 1 second argument. On very slow systems, that syscall may take arbitrary amount of time. I wouldn't like to relax the regexp as it would make the test result less reliable." — https://sourceforge.net/p/strace/mailman/message/35250158/ May be you have any ideas regarding possibilities of fixing the environment in order to get nanosleep? Or is it confirmed issue on zSeries? > > Andreas. > > -- > Andreas Schwab, SUSE Labs, sch...@suse.de > GPG Key fingerprint = 0196 BAD8 1CE9 1970 F4BE 1748 E4D4 88E3 0EEA B9D7 > "And now for something completely different." > > ------------------------------------------------------------------------------ > Check out the vibrant tech community on one of the world's most > engaging tech sites, SlashDot.org! http://sdm.link/slashdot > _______________________________________________ > Strace-devel mailing list > Strace-devel@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/strace-devel -- Eugene "eSyr" Syromyatnikov mailto:evg...@gmail.com xmpp:eSyr@jabber.{ru|org} ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Strace-devel mailing list Strace-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/strace-devel
