Antoine Pitrou added the comment: multidict is a package, the Cython module is multidict._multidict.
Cython translated "import sys" into this: __pyx_t_1 = __Pyx_Import(__pyx_n_s_sys, 0, -1); if (unlikely(!__pyx_t_1)) __PYX_ERR(0, 5, __pyx_L1_error) And __Pyx_Import is this: https://gist.github.com/pitrou/9a0d94aba3495ce3eb8630d4797d67bb Note that __Pyx_MODULE_NAME is defined thusly: #define __Pyx_MODULE_NAME "multidict._multidict" So perhaps Cython is indeed attempting a PyImport_ImportModuleLevelObject() call with a level of 1 for "import sys" before falling back on a level of -1... Why I don't know. (also since __Pyx_MODULE_NAME seems known, Cython could actually define __package__) ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue25791> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
