This introduces 'ctdb-test', a program for testing libctdb. It takes commands on standard input (with reduced functionality) or an input file. It still needs some cleaning up, but you can uncover a bug in libctdb today simply by running a simple attachdb test: $ ctdb-test tests/attachdb1.txt It will print out a crash, and the path of successful and failed operations which lead to it: ... Child signalled 11 on failure path: [malloc]:1:S[socket]:1:S[connect]:1:S[malloc]:1:S[malloc]:1:S[malloc]:1:S[malloc]:4:S[malloc]:4:F Feed that failure path into ctdb-test using --failpath (under a debugger): gdb --args ctdb-test tests/attachdb1.txt --failpath=[malloc]:1:S[socket]:1:S[connect]:1:S[malloc]:1:S[malloc]:1:S[malloc]:1:S[malloc]:4:S[malloc]:4:F And you hit the exact error. It is based on the fork-to-fail model of nfsim. The relevant parts are from page 154 of the proceedings of 2005 Ottawa Linux Symposium Volume II: http://www.linuxsymposium.org/2005/linuxsymposium_procv2.pdf Or our presentation of same (from slide 21): http://ozlabs.org/~jk/projects/nfsim/nfsim.sxi Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (This used to be ctdb commit b4aab4199a57898877b6545a54f212087ed4b35a)
