There is even a basis for that already, we have a testsuite for the zfs send -> btrfs receive feature at git://git.kernel.org/pub/scm/linux/kernel/git/arne/far-progs.git see test.pl. It can also already be used to test btrfs send -> btrfs receive. -Arne > > thanks, > liubo > >> >> If yes, to whom do they need to keep in touch for guidance. >> >> Thank you, >> Kiran Patil (Director) >> Green Turtles Technologies, INDIA. >> -- >> To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in >> the body of a message to majordomo@vger.kernel.org >> More majordomo info at http://vger.kernel.org/majordomo-info.html > -- > To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html ^ permalink raw reply [flat|nested] 9+ messages in thread

By any chance, are these the same people behind http://sourceforge.net/projects/btrfstest/ ? > Is there space for them to contribute? Sure. As an example of where to start, look at a some patches from Miao Xie with reproducers for several bugs. This IMHO is a smooth path to start with xfstests, the task is to embody the test itself into the teitesinfrastructure. The more advanced tasks: * look at commits in btrfs and try to write a specific test for them (depends on the nature of the bug, the difficulty ranges from easy to impossible) * write test coverage for a particular feature (eg. for Jeff Liu's label setting patches) * several btrfs specific xfstests were sent to the mailinglists over time, I'm sure not all of them were merged > If yes, to whom do they need to keep in touch for guidance. You can learn a lot from existing xfstests and review comments of proposed tests. Feel free to ask in the respective mailinglists or IRC channels. david ^ permalink raw reply [flat|nested] 9+ messages in thread

If so, you might want to consider that http://www.tuxera.com/community/posix-test-suite/ probably already covers some of the tests that "btrfstest" is (re)writing. i.e.: +/* Creating Link on non-existing prefix path should return ENOTDIR and +/* Creating link on ENAMETOOLONG if either file name exceeds maximum characters are almost certainly covered in the above posix test suite.

(cc: xfs list) Are you thinking of writing new tests, or doing more formal testing with the existing testsuite? Both would be useful. In particular, any time there's a bugfix, a regression test is helpful. Generic new tests of btrfs functionality would be good, too. I would suggest starting with a couple new tests, and cc: the xfs list for review. In the course of the review you'll get a sense of the various conventions used in xfstests, etc. Simply running xfstests over various btrfs configurations would also be useful, to be sure any regressions caught by existing tests don't go unnoticed. thanks, -Eric > Thank you, > Kiran Patil (Director) > Green Turtles Technologies, INDIA. ^ permalink raw reply [flat|nested] 9+ messages in thread
