Issue #2922: missing os.waitid exposure (pypy/pypy)
by Joshua Oreman 28 Nov '18

28 Nov '18

New issue 2922: missing os.waitid exposure https://bitbucket.org/pypy/pypy/issues/2922/missing-oswaitid-exposure Joshua Oreman: CPython exposes os.waitid() on platforms where waitid() is defined by the system C library, which among other features allows one to wait for a process to exit without consuming its exit status. It would be useful to be able to use this on PyPy as well, along with the associated os.P_PID/os.P_PGID/os.P_ANY and os.WEXITED/os.WNOWAIT/etc constants.

Issue #2921: missing select.KQ_NOTE_* exposures on kqueue platforms (pypy/pypy)
by Joshua Oreman 28 Nov '18

28 Nov '18

New issue 2921: missing select.KQ_NOTE_* exposures on kqueue platforms https://bitbucket.org/pypy/pypy/issues/2921/missing-selectkq_note_-exposure… Joshua Oreman: On kqueue platforms such as OS X, if the system headers define NOTE_FOO, it gets exposed under CPython as a Python constant select.KQ_NOTE_FOO, for values of FOO in (ATTRIB, CHILD, DELETE, EXEC, EXIT, EXTEND, FORK, LINK, LOWAT, RENAME, REVOKE, TRACK, TRACKERR, WRITE). It would be useful for PyPy to replicate this behavior, since it is otherwise difficult to use some kqueue filters without groveling in system headers for the right values for the NOTE constants.

Issue #2916: py3.6 variable annotation breaks ternary expression (pypy/pypy)
by Ryan Hileman 18 Nov '18

18 Nov '18

New issue 2916: py3.6 variable annotation breaks ternary expression https://bitbucket.org/pypy/pypy/issues/2916/py36-variable-annotation-breaks… Ryan Hileman: `var: bool = True if False else False` In python3.6, this sets `var` to `False`. In pypy's py3.6 branch, it sets `var` to `(True, False, False)`. Seems like a parsing or AST error. pypy3: ``` 2 0 LOAD_CONST 1 ((True, False, False)) 2 STORE_FAST 0 (var) 4 LOAD_CONST 0 (None) 6 RETURN_VALUE ``` python3.7: ``` 2 0 LOAD_CONST 1 (False) 2 POP_JUMP_IF_FALSE 8 4 LOAD_CONST 2 (True) 6 JUMP_FORWARD 2 (to 10) >> 8 LOAD_CONST 1 (False) >> 10 STORE_FAST 0 (var) 12 LOAD_CONST 0 (None) 14 RETURN_VALUE ``` Is this a bug in constant folding? This works as expected: ``` var: bool var = True if False else False ```
