PEP 427 comment: code signing
by martin＠v.loewis.de Oct. 23, 2012

Oct. 23, 2012

I'm -1 on the usage of ed25519 in PEP 427. While the PEP proposes to use JSON Web signatures, this algorithm is not supported by the current JWS draft [1]. Instead, I suggest to use the ES256 algorithm from JWS, i.e. ECDSA with the NIST P-256 curve and SHA-256. This has the advantage of using standard algorithms [2]. I don't know what the rationale for suggesting ed25519 is; I suppose that existence of a pure-Python implementation played a role. However: - ECDSA also has a pure-Python … [View More]

PEP 427: pure / plat distinction
by Antoine Pitrou Oct. 22, 2012

Oct. 22, 2012

Hello, How does the pure / plat distinction as outlined in PEP 427 cope with Debian's system of separating installed files into pyshared (for *.py and *.egg-info files) and pythonX.Y/dist-packages (for *.pyc and *.so files)? Thanks, Antoine.

For VS 2010 I decided against this approach and built the extension as a separate .pyd extension because the _sha3 module is rather large (> 200 kB). I think your change is going to break VS … [View More]

return type of __complex__
by Antonio Cuni Oct. 22, 2012

Oct. 22, 2012

Hi, while fixing pypy to pass CPython 3.2 tests, I found what I think it's a inconsistency in how CPython (both 2.7 and 3.2) handles __complex__: >>> class Obj: ... def __complex__(self): ... return 2.0 ... >>> obj = Obj() >>> complex(obj) (2+0j) >>> >>> import cmath >>> cmath.acos(obj) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: __complex__ should return a complex object i.… [View More]

Web accessible core code search and other devguide questions
by anatoly techtonik Oct. 22, 2012

Oct. 22, 2012

Hi again, http://docs.python.org/devguide/faq.html?highlight=search What can I use to browse, search and troubleshoot core Python sources online? Why the question "Where do I find Python core code?" is not the first in the dev. guide? =) There is clearly a lot of stuff on http://hg.python.org/ that requires some guidance. I'd also include some more technical information at the top. And FAQ is very strange. "What standards of behaviour are expected in these communication channels?" - is … [View More]

Oct. 21, 2012

Hi, I'm the author of sh.py, a subprocess module rewrite for Linux and OSX. It serves as a powerful and intuitive interface to launching subprocesses http://amoffat.github.com/sh/. It has been maintained on github https://github.com/amoffat/sh for about 10 months and currently has about 25k installs, according to pythonpackages.com. Andy Grover maintains the Fedora rpm for sh.py http://arm.koji.fedoraproject.org/koji/buildinfo?buildID=94247 and Nick Moffit has submitted an older version of … [View More]

Improved evaluator added to ast module
by Vinay Sajip Oct. 20, 2012

Oct. 20, 2012

In response to http://bugs.python.org/issue15452, I've created an improved evaluator in the ast module in my sandbox repo. The evaluator supports lookup of names in a supplied namespace. The basic interface is def lookup_eval(source_string_or_ast_node, namespace, allow_imports=False): # perform limited evaluation of Python expressions Function calls are not allowed in expressions, but the following are: * Names (looked up in namespace, and imported if not found there and allow_imports … [View More]

Rejecting PEPs 407 and 413?
by Nick Coghlan Oct. 19, 2012

Oct. 19, 2012

With the 3.4 release PEP published using a traditional schedule, perhaps MvL would care to do the honours as BDFL-Delegate in rejecting the two "faster release cycle for the standard library" PEPs? (I know I asked to hold off on that when MvL last brought it up, but I've since realised that "do the first alpha early" isn't a stand-alone PEP, it's just a matter of convincing Larry it's worthwhile and negotiating timing with the release team after there are some release-worthy features on trunk) … [View More]

PEP 426 comment: field order
by martin＠v.loewis.de Oct. 19, 2012

Oct. 19, 2012

I'd like to request that PEP 426 is extended to talk about the order of fields. In particular, for the Extension field, is it necessary that all "additional tags" follow immediately the respective Extension field? I also request that RFC 2119 terminology is followed strictly. In particular, the phrasing "Additional tags defined by the extension should be of the form string/Name:" is unclear - under what "particular circumstances" can I deviate from that requirement, i.e. use some form … [View More]
