[issue833] missing functions in the os module
by teepark 13 May '14

13 May '14

New submission from teepark <travis.parker(a)gmail.com>: I ran into this when I needed os.fchmod, but there are quite a few names not present in pypy's os module (I'm on x86_64 linux, and I'm sure many of these aren't guaranteed to be there for any platform, but pypy on x86_64 linux should probably include them): - getlogin - confstr - getresgid - tcsetpgrp - statvfs - setresgid - initgroups - fstatvfs - getresuid - fchmod - setresuid - tcgetpgrp - confstr_names - setgroups - pathconf - fchown - openpty - ctermid - statvfs_result Please change the priority if "feature" isn't appropriate - it doesn't feel right but I don't know that cpython compatibility issues are being treated as bugs. ---------- messages: 2975 nosy: pypy-issue, teepark priority: feature status: unread title: missing functions in the os module ________________________________________ PyPy bug tracker <tracker(a)bugs.pypy.org> <https://bugs.pypy.org/issue833> ________________________________________

[issue644] Add option parser to package.py
by Dan 09 May '14

09 May '14

New submission from Dan <dcolish(a)gmail.com>: I've been using package.py a lot more often now and I find an option parser interface to be nice for command line scripts. I've written one for package.py, but I believe it will require buildbot updates since buildbot is calling the old interface. ---------- effort: ??? files: package.diff messages: 2169 nosy: dcolish, pypy-issue priority: wish release: ??? status: in-progress title: Add option parser to package.py _______________________________________________________ PyPy development tracker <pypy-dev-issue(a)codespeak.net> <https://codespeak.net/issue/pypy-dev/issue644> _______________________________________________________

[issue662] get_config_vars has nothing for CC, while expected internally
by Martijn 08 May '14

08 May '14

New submission from Martijn <ss(a)kleptog.org>: Currently distutils.sysconfig.get_config_vars() has no value for CC. This means that when you try to build a C extension using distutils it breaks, because distutils internally uses get_config_vars() to determine the compiler (distutils/ccompiler.py). Attached is a patch that works for me, with this C extensions build normally (excluding cpyext problems). But this may be a layering violation, so I'll leave it to you guys to determine the correct fix. In any case it's an improvement which improves compatibility. ---------- effort: ??? files: distutils.patch messages: 2267 nosy: kleptog, pypy-issue priority: feature release: ??? status: unread title: get_config_vars has nothing for CC, while expected internally _______________________________________________________ PyPy development tracker <pypy-dev-issue(a)codespeak.net> <https://codespeak.net/issue/pypy-dev/issue662> _______________________________________________________

[issue733] bz2 decompression is very slow
by Jonas H. 23 Apr '14

23 Apr '14

New submission from Jonas H. <jonas(a)lophus.org>: Compared to CPython 2.7, PyPy 1.5 (from the Arch Linux repositories) seems to be ~5 times slower on bz2 decompression. Using this script: from bz2 import BZ2File with BZ2File(sys.argv[1]) as f: while True: if not f.read(8*1024): break to decompress the PyPy lib-python/ directory (60M compressed) takes about 5 seconds on CPython and 20s on PyPy 1.5. ---------- messages: 2569 nosy: jonash, pypy-issue priority: bug release: 1.5 status: unread title: bz2 decompression is very slow ________________________________________ PyPy bug tracker <tracker(a)bugs.pypy.org> <https://bugs.pypy.org/issue733> ________________________________________

[issue931] web site bugs
by Armin Rigo 23 Apr '14

23 Apr '14

New submission from Armin Rigo <armin.rigo(a)gmail.com>: On the web site http://pypy.org: home page -> click "donate to py3k" -> click "read proposal" it ends up selecting "donate to numpy" again, which is confusing. Also the text "This donation will go towards supporting NumPy in PyPy Read proposal" would be more readable with a dot or a line break. ---------- messages: 3447 nosy: arigo, pypy-issue priority: bug status: unread title: web site bugs ________________________________________ PyPy bug tracker <tracker(a)bugs.pypy.org> <https://bugs.pypy.org/issue931> ________________________________________
