Python 2.7 root buildbot showing errors
by Chris Angelico 06 Jan '14

06 Jan '14

The first build my new root buildbot did showed errors in the 2.7 test suite, but I thought little of it as quite a few other 2.7 buildbots are showing red, too. But it seems they're showing different errors, so there might be something wrong with the setup. http://buildbot.python.org/all/builders/AMD64%20Debian%20root%202.7/builds/… First off, it's complaining about being unable to build _curses (lacking curses.h). Is that a mandatory prereq that I should install, or should Python be compatible with not having it? Then further down, several SSL tests attempt: s.connect_ex(("svn.python.org", 444))) and get back EAGAIN when they're expecting ECONNREFUSED. Possibly my firewall's delaying things somewhat and it's timing out with a signal; when I try manually, the connection times out. Are these failures a problem? Should they be fixed? The 3.x builds are all coming up green. ChrisA

Subclasses vs. special methods
by Serhiy Storchaka 06 Jan '14

06 Jan '14

Should implicit converting an instance of int, float, complex, str, bytes, etc subclasses to call appropriate special method __int__ (or __index__), __float__, __complex__, __str__, __bytes__, etc? Currently explicit converting calls these methods, but implicit converting doesn't. >>> class I(int): ... def __int__(self): return 42 ... def __index__(self): return 43 ... >>> class F(float): ... def __float__(self): return 42.0 ... >>> class S(str): ... def __str__(self): return '*' ... >>> int(I(65)) 42 >>> float(F(65)) 42.0 >>> str(S('A')) '*' >>> chr(I(65)) 'A' >>> import cmath; cmath.rect(F(65), 0) (65+0j) >>> ord(S('A')) 65 Issue17576 [1] proposes to call special methods for implicit converting. I have doubts about this. 1. I afraid that this will adds places where arbitrary Python code is unexpectedly called. For example see changeset9a61be172c23 discussed in neighbor thread. If the "k" format code will call __int__(), Python code can modify unpacked list argument during parsing arguments in PyArg_ParseTuple(). 2. PyLong_As*() functions already is not very consistent. Some of them calls __int__() for argument which is not an instance of int subclass, other accepts only instances of int subclasses. PyLong_AsVoidPtr() calls or not calls __int__() depending on the sign of the argument. 3. We can't consistency call special methods for all types. E.g. for strings we can't call __str__() when processing the "s" code in PyArg_ParseTuple() because this will cause a leak. I think that overriding special converting method in a subclass of corresponding type should be restricted. I see two consistent and safe possibilities: 1. Forbidden. I.e. above declarations of I, F and S classes should raise exceptions. 2. Has no effect. I.e. both int(I(65)) and operator.index(I(65)) should return 65. [1] http://bugs.python.org/issue17576

[RELEASE] libmpdec-2.4.0 (suitable for compiling _decimal)
by Stefan Krah 06 Jan '14

06 Jan '14

Hi, I've released libmpdec-2.4.0, which can be used to compile _decimal with the "--with-system-libmpdec" configure option: http://www.bytereef.org/mpdecimal/download.html libmpdec-2.4.0 is exactly the same as the one in the CPython source tree. The API is stable and the libmpdec-2.x.y series will stay binary compatible [1]. Stefan Krah [1] Starting from 2.4.0: 2.4.0 is not binary compatible with 2.3.

Bug? http.client assumes iso-8859-1 encoding of HTTP headers
by Hugo G. Fierro 05 Jan '14

05 Jan '14

Hi Python devs, I am trying to download an HTML document. I get an HTTP 301 (Moved Permanently) with a UTF-8 encoded Location header and http.client decodes it as iso-8859-1. When there's a non-ASCII character in the redirect URL then I can't download the document. In client.py def parse_headers() I see the call to decode('iso-8859-1'). My personal hack is to use whatever charset is defined in the Content-Type HTTP header (utf8) or fall back into iso-8859-1. At this point I am not sure where/how a fix should occur so I thought I'd run it by you in case I should file a bug. Note that I don't use http.client directly, but through the python-requests library. I include some code to reproduce the problem below. Cheers, Hugo ----- #!/usr/bin/env python3 # Trying to replicate what wget does with a 301 redirect: # wget --server-response www.starbucks.com/store/158/AT/Karntnerstrasse/K%c3%a4rntnerstrasse-49-Vien… import http.client import urllib.parse s2='/store/158/AT/Karntnerstrasse/K%c3%a4rntnerstrasse-49-Vienna-9-1010' s3=' http://www.starbucks.com/store/158/at/karntnerstrasse/k%C3%A4rntnerstrasse-… ' conn = http.client.HTTPConnection('www.starbucks.com') conn.request('GET', s2) r = conn.getresponse() print('Location', r.headers.get('Location')) print('Expected', urllib.parse.unquote(s3)) assert r.status == 301 assert r.headers.get('Location') == urllib.parse.unquote(s3), \ 'decoded as iso-8859-1 instead of utf8' conn = http.client.HTTPConnection('www.starbucks.com') conn.request('GET', s3) r = conn.getresponse() assert r.status == 200
