Detect cycle during projectivize (#10877) * detect cycle during projectivize * not complete test to detect cycle in projectivize * boolean to int type to propagate error * use unordered_set instead of set * moved error message to errors * removed cycle from test case * use find instead of count * cycle check: only perform one lookup * Return bool again from _has_head_as_ancestor Communicate presence of cycles through an output argument. * Switch to returning std::pair to encode presence of a cycle The has_cycle pointer is too easy to misuse. Ideally, we would have a sum type like Rust's `Result` here, but C++ is not there yet. * _is_non_proj_arc: clarify what we are returning * _has_head_as_ancestor: remove count We are now explicitly checking for cycles, so the algorithm must always terminate. Either we encounter the head, we find a root, or a cycle. * _is_nonproj_arc: simplify condition * Another refactor using C++ exceptions * Remove unused error code * Print graph with cycle on exception * Include .hh files in source package * Add FIXME comment * cycle detection test * find cycle when starting from problematic vertex Co-authored-by: Daniël de Kok <me@danieldk.eu> 2022-06-08 20:34:11 +03:00			`from libcpp.string cimport string`
