New submission from Buck Golemon: In order to make an inheritable pipe, the code is quite a bit different between posixes that implement pipe2 and those that don't (osx, mainly). I believe the officially-supported path is to call os.pipe() then os.setinheritable(). This seems objectionable since set_inheritable() code is invoked twice, where I'd prefer to invoke it zero times (or at most once).
Would it be acceptable to implement a pipe2 shim for those platforms? If so, I'll (attempt to) provide a patch. Alternatively, can we change the signature of os.pipe() to os.pipe(flags=O_CLOEXEC) ? In my opinion, such a function could be implemented via pipe2 on those platforms that provide it, obviating any need for an os.pipe2. Please tell me which patch to provide, if any. ---------- messages: 229947 nosy: bukzor priority: normal severity: normal status: open title: inheritable pipes are unwieldy without os.pipe2 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22722> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
