About the failing test sage -t -force_lib "devel/sage/sage/graphs/digraph.py" # Killed/ crashed I ran the test again with -verbose
I think its connected to the routine dcycle.feedback_edge_set (in line 1252) and maybe its an integer / floating error Trying: cycle.size()###line 1338:_sage_ >>> cycle.size() Expecting: 5 # >>> dcycle.feedback_edge_set(value_only=True) 5.0 ********************************************************************** File "/mnt/sda6/COMPILE/sage-4.7.2/devel/sage/sage/graphs/digraph.py", line 998, in __main__.example_22 Failed example: cycle.size()###line 1338:_sage_ >>> cycle.size() Expected: 5 # >>> dcycle.feedback_edge_set(value_only=True) 5.0 Got: 5 and then: Trying: feedback = dg.feedback_edge_set()###line 1348:_sage_ >>> feedback = dg.feedback_edge_set() Expecting nothing Assertion failed: orig->m > 0 && orig->n > 0 Error detected in file glpapi09.c at line 289 /mnt/sda6/COMPILE/sage-4.7.2/local/lib/libcsage.so(print_backtrace +0x3b)[0xb71f231e] /mnt/sda6/COMPILE/sage-4.7.2/local/lib/libcsage.so(sigdie+0x17) [0xb71f235e] /mnt/sda6/COMPILE/sage-4.7.2/local/lib/libcsage.so(sage_signal_handler +0x1c4)[0xb71f1e97] [0xffffe400] /lib/libc.so.6(abort+0x182)[0xb7472ab2] /usr/local/lib/libglpk.so.0(+0x43b0e)[0xaea1eb0e] /usr/local/lib/libglpk.so.0(+0x439ff)[0xaea1e9ff] /usr/local/lib/libglpk.so.0(glp_intopt+0xae0)[0xae9e89b0] /mnt/sda6/COMPILE/sage-4.7.2/local/lib/python/site-packages/sage/ numerical/backends/glpk_backend.so(+0x5c47)[0xaea99c47] /mnt/sda6/COMPILE/sage-4.7.2/local/lib/python/site-packages/sage/ numerical/mip.so(+0x29036)[0xb0bcf036] /mnt/sda6/COMPILE/sage-4.7.2/local/lib/libpython2.6.so. 1.0(PyCFunction_Call+0x128)[0xb7642c58] .lotsof that sort.. /mnt/sda6/COMPILE/sage-4.7.2/local/lib/libpython2.6.so.1.0(Py_Main +0xc7d)[0xb76d0c5d] python(main+0x27)[0x8048667] /lib/libc.so.6(__libc_start_main+0xe6)[0xb745bbc6] python[0x80485a1] ------------------------------------------------------------------------ Unhandled SIGABRT: An abort() occurred in Sage. This probably occurred because a *compiled* component of Sage has a bug in it and is not properly wrapped with sig_on(), sig_off(). You might want to run Sage under gdb with 'sage -gdb' to debug this. Sage will now terminate. ------------------------------------------------------------------------ The doctested process was killed by signal 6 [5.7 s] Personally I am fine with doctesting rm -rf /. People who run as root will handle it with dignity (ouch, maybe not?). -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
