0.25.2b0 with 32bit fixes: (sometimes) Interrupted system call in builtin_subtype_methods_T653
by Yaroslav Halchenko July 6, 2017

July 6, 2017

A fresh one I ran into while rebuilding with fixes for 32bit (thanks BTW! sorry for not prompt followup/gratitude) ====================================================================== ERROR: runTest (__main__.CythonRunTestCase) compiling (cpp) and running builtin_subtype_methods_T653 ---------------------------------------------------------------------- Traceback (most recent call last): File "runtests.py", line 998, in run self.run_tests(result, ext_so_path) File "runtests.py", line 1013, in run_tests self.run_doctests(self.module, result, ext_so_path) File "runtests.py", line 1023, in run_doctests run_forked_test(result, run_test, self.shortDescription(), self.fork) File "runtests.py", line 1076, in run_forked_test cid, result_code = os.waitpid(child_id, 0) OSError: [Errno 4] Interrupted system call ---------------------------------------------------------------------- Ran 581 tests in 188.225s FAILED (errors=1) it is not 100% reproducible. Rebuilding the package went smooth without this hiccup. Just wanted to let you know might be related that the tests were ran as set -e; for P in 2.7 3.5; do \ PYTHONPATH=`/bin/ls -d /build/cython-0.25.2~b0/build/lib.*-$P` \ /usr/bin/python$P runtests.py --shard_count=16 \ --no-refnanny -v -v --exclude="(parallel|Debugger|annotate_html)" --work-dir=build/work-dir 2>&1; \ done so testing in parallel to speed up the build of the package. This one was the only failure I have ran into but it built fine before (but there could have been some changes in the core packages since then) -- Yaroslav O.

q re environment for successful test suite run
by James C. McPherson Nov. 14, 2016

Nov. 14, 2016

Hi all, I'm building Cython 0.24.1 for Solaris and I'm finding it difficult to get the test suite to run successfully. I've tried several different versions of gcc (4.9, 5.3, 5.4) and Solaris Studio (12.4), but to no avail. For starters, here's the first lot of errors from gcc 5.4 in 32bit mode against python2.7: warning: BUILD/inline/_cython_inline_d1a30658ebea82281640c5ea0e1db57e.pyx:6:4: Unreachable code warning: BUILD/inline/_cython_inline_121fdd47c08e20991f90b2566f9a1705.pyx:6:4: Unreachable code warning: BUILD/inline/_cython_inline_a938867fe92f83497d786ebdab9e4e1d.pyx:7:4: Unreachable code BUILD/inline/_cython_inline_a938867fe92f83497d786ebdab9e4e1d.c: In function '__pyx_pf_5numpy_7ndarray___getbuffer__': BUILD/inline/_cython_inline_a938867fe92f83497d786ebdab9e4e1d.c:1522:50: error: 'NPY_C_CONTIGUOUS' undeclared (first use in this function) __pyx_t_2 = ((!(PyArray_CHKFLAGS(__pyx_v_self, NPY_C_CONTIGUOUS) != 0)) != 0); ^ BUILD/inline/_cython_inline_a938867fe92f83497d786ebdab9e4e1d.c:1522:50: note: each undeclared identifier is reported only once for each function it appears in BUILD/inline/_cython_inline_a938867fe92f83497d786ebdab9e4e1d.c:1586:50: error: 'NPY_F_CONTIGUOUS' undeclared (first use in this function) __pyx_t_2 = ((!(PyArray_CHKFLAGS(__pyx_v_self, NPY_F_CONTIGUOUS) != 0)) != 0); ^ When you run the test suite, what combination of compiler(s), python interpreter(s) and CFLAGS/CXXFLAGS are used?
