[issue5364] documentation in epub format
James Polley jamezpol...@gmail.com added the comment: It looks like the first release that had epub support was 1.0; docs.python.org is still using 0.6.7, according to the footer on the bottom of the page. I suspect that this is (A) pending the upgrade to 1.0.0, which is (B) more difficult than it sounds like, or at least, needs someone to make a concerted effort, and (C) should automatically just happen (or at least, be fairly trivial) once the move to the new version happens. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue5364 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue13531] add test for defaultdict with non-callable first argument
New submission from mike c coolbutusel...@gmail.com:
Could a test be added to ./Lib/test/test_defaultdict.py to test for TypeError
being thrown when the the first argument to collections.defaultdict is not
callable?
pypy does not behave the same way as CPython 2.7.2 as the problem is not
covered in the testcases.
e.g.
def test_callable_arg:
d1 = defaultdict({})
self.assertRaises(TypeError) # TypeError: first argument must be callable

[issue13533] Would like Py_Initialize to play friendly with host app
New submission from dangermouseb da...@bigredmedia.tv: I'm building a dll add-in (on Windows) in which I want to use the installed version of Python, not provide my own installation. When py_initialize fails it appears to call exit(). This doesn't seem very friendly behaviour for an embeddable scripting language as the host application is terminated (out of my control). So my request is that either py_initialize is changed to return a code indicating failure or sucess or another function is added to th api to test if the installation is good or not. That way I can report to the user that there is a problem in the python installation rather than apparently crashing the host app. Currently the only strategy I've thought of to get around this is to fork a seperate process, and inspect it after a delay to see if it is running (indicating that py_initialize hasn't failed), terminate the new process and then call py_initialize in the host application process. This has been raised before but only in terms of consistency with the documentation, not about if a embeddable scripting engine should terminate the hosting process without regard to that host. Many thanks, David -- components: None messages: 148875 nosy: dangermouseb priority: normal severity: normal status: open title: Would like Py_Initialize to play friendly with host app type: feature request versions: Python 2.7, Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13533 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue11051] system calls per import
Martin v. Löwis mar...@v.loewis.de added the comment: First, I don't understand why we need to check both foo.so and foomodule.so. Because we always did, i.e. changing it now may break backwards compatibility. Now, as for why we always had *module.so also: it may be that calling an extension module foo.so might not be feasible if it needs to link with a system library called foo.so (rather than libfoo.so). I don't know how serious this problem is in practice - we may consider deprecating-then-removing *module.so from the import machinery. As for checking both foo.so and foo.cpython-32m.so: that's for backwards compatibility also. Existing build processes may produce foo.so, as they did in previous Python versions (in particular, if they are not based on distutils, but, say, make). Unfortunately, PEP 3149 did not specify a deprecation scheduling. You could ask Barry - I suppose that was an oversight, and not actually deliberate. Of course, with .cpython-32m.so being present, removing *module.so would be easy enough, except again for breaking existing projects which might use that name. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11051 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Received value insufficiently close to expected value.
It turns out (after much debugging) that libm in this version of glibc has an
architecture-specific implementation of hypot(3) which returns inf in many of
the test cases in tests/cmath_testcases.txt, when the non-architecture-specific
implementation returns large finite values.
See downstream bug in Fedora's bug tracker:
https://bugzilla.redhat.com/show_bug.cgi?id=750811
for more details.
Seen with the Python 2.7.2 tarball, but the code doesn't appear to have changed
in hg in either the default or the 2.7 branches.
I will also file a bug in glibc's bug tracker about this.

[issue13535] Improved two's complement arithmetic support: to_signed() and to_unsigned()
New submission from Nick Coghlan ncogh...@gmail.com:
This RFE proposes two new methods to_signed and to_unsigned on 'int'
objects and on the numbers.Integral ABC.
Semantics (and number.Integral implementation):
def to_unsigned(self, bits):
Convert this integer to its unsigned two's complement equivalent for the
given bit length
if self.bit_length() = bits:
raise ValueError({} is too large for {}-bit two's complement
precision.format(self, bits))
if self = 0:
return self
return 2**bits + self # self is known to be negative at this point
def to_signed(self, bits):
Convert an integer in two's complement format to its signed equivalent for
the given bit length
if self 0:
raise ValueError({} is already signed.format(self))
if self.bit_length() bits:
raise ValueError({} is too large for {}-bit two's complement
precision.format(self, bits))
upper_bound = 2**bits
if self (upper_bound / 2):
return self
return upper_bound - self
To add these methods to numbers.Integral, a concrete
numbers.Integral.bit_length() operation will also be needed. This can be
implemented simply as:
def bit_length(self):
return int(self).bit_length()

[issue13536] ast.literal_eval fails on sets
Alex Gaynor alex.gay...@gmail.com added the comment: There's no support for comprehensions of any sort, and confusingly limited support for arithmetic ops, I'd like to keep the scope of this issue small, basically backporting 90bf0631bfb8 and adding the tests (which I can also add to default). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13536 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue13520] Patch to make pickle aware of __qualname__
Alexandre Vassalotti alexan...@peadrop.com added the comment: This might not be the case anymore, but __module__ can sometime be None. There is some discussion about this in Issue 3657. We should define the expected behavior when this happens. Also, I don't think backward-compatibility of the protocol is a big issue if we use the getattr approach. I feel bumping the protocol version is only necessary if we introduce new opcodes or change their interpretation. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13520 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue13505] Bytes objects pickled in 3.x with protocol =2 are unpickled incorrectly in 2.x
Alexandre Vassalotti alexan...@peadrop.com added the comment:
I think we are kind of stuck here. I might need to rely on some clever hack to
generate the desired str object in 2.7 without breaking the bytes support in
3.3 and without changing 2.7 itself.
One *dirty* trick I am thinking about would be to use something like
array.tostring() to construct the byte string.
from array import array
class bytes:
def __reduce__(self):
return (array.tostring, (array('B', self),))
Of course, this doesn't work because pickle doesn't method pickling. But, maybe
someone can figure out a way around this... I don't know.
Also, this is a bit annoying to fix since we changed the semantic meaning of
the STRING opcodes in 3.x---i.e., it now represents a unicode string instead of
a byte string.

[issue3635] pickle.dumps cannot save instance of dict-derived class that overrides __getattribute__
Alexandre Vassalotti alexan...@peadrop.com added the comment: I don't think it is a bug. The posted code completely breaks the expected behavior of __getattribute__. With a such implementation, there is nothing we can do with this object as we cannot introspect it. Use the following if you really need this kind of behaviour: class E(dict): def __getattribute__(self,name): try: return self[name] except KeyError: return dict.__getattribute__(self, name) -- resolution: - works for me status: open - closed ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue3635 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
