[issue17336] Complex number representation round-trip doesn't work with signed zero values
New submission from Manuel Jacob:
When evaluating, signed zero complex numbers aren't recovered correctly.
-0j
(-0-0j)
(-0-0j)
0j
0j
0j
According to
http://docs.python.org/dev/reference/datamodel.html#object.__repr__ the
representation can be used to recreate an object with the same value. Shouldn't
this also be possible with complex numbers?
When using complex('...'), round-trip works correctly. While this can be used
to recover the exact number, i find it confusing that complex('...') isn't the
same as eval('...').
complex('-0j')
-0j
complex('(-0-0j)')
(-0-0j)
complex('0j')
0j

[issue10967] move regrtest over to using more unittest infrastructure
Ezio Melotti added the comment: For one thing, I think resources could be implemented in terms of skips While working on #17333 I noticed a related problem. Most of the tests in test_imaplib are skipped if the 'network' resource is not specified. The test contains the following lines to enable those tests when the file is executed directly: if __name__ == __main__: support.use_resources = ['network'] unittest.main() but this clearly doesn't work while using unittest discovery, so those tests are skipped. Implementing resources as skips makes sense, but we might also need a way to specify what resources are needed that works with unittest discovery. Running these tests only when the test file is executed directly or through `regrtest -u` is also an option. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10967 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue17337] input() and raw_input() do not work correctly with colored prompts
New submission from mic_e: With a prompt that uses ANSI color escape codes, python3 input() and python2 raw_input() behave incorrectly when it comes to the wrapping of the first line - almost certainly due to the wrong string length calculation. The line breaking occurs k characters early, where k is the number of characters in the ANSI escape sequence. Even worse, the line break does not switch to the next line, but instead jumps back to the beginning, overwriting the prompt and the previously written input. How to reproduce: Call input() with a color-coded string as argument, and type until you would expect the usual line break. Example: mic@mic-nb ~ $ python3 Python 3.3.0 (default, Dec 22 2012, 21:02:07) [GCC 4.7.2] on linux Type help, copyright, credits or license for more information. prompt=\x1b[31;1mthis is a bold red prompt \x1b[m len(prompt) 37 input(prompt) uvwxyzs a bold red prompt abcdefghijklmnopqrst 'abcdefghijklmnopqrstuvwxyz' mic@mic-nb ~ $ python2 Python 2.7.3 (default, Dec 22 2012, 21:14:12) [GCC 4.7.2] on linux2 Type help, copyright, credits or license for more information. prompt=\x1b[31;1mthis is a bold red prompt \x1b[m len(prompt) 37 raw_input(prompt) uvwxyzs a bold red prompt abcdefghijklmnopqrst 'abcdefghijklmnopqrstuvwxyz' mic@mic-nb ~ $ tput cols 57 I have typed directly after the prompt the string 'abcdefghijklmnopqrstuvwxyz', so the expected result would be be this is a bold red prompt abcdefghijklmnopqrstuvwxyz with four more characters of space before the line break Note that the break occurs exactly 8 characters early, which is the total amount of ANSI escape sequence characters. Also note that the readline module is impored in my .pyrc file. -- components: Library (Lib) messages: 183323 nosy: mic_e priority: normal severity: normal status: open title: input() and raw_input() do not work correctly with colored prompts type: behavior versions: Python 2.7, Python 3.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17337 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue17337] input() and raw_input() do not work correctly with colored prompts
Michael Enßlin added the comment:
The issue might very well be strictly related to GNU readline.
I have both successfully reproduced it in a C program:
#include stdio.h
#include readline/readline.h
int main() {
readline(\x1b[31;1mthis is a bold red prompt\x1b[m );
}
gcc -lreadline test.c
and found a fix, hinted at by this stackoverflow post:
http://stackoverflow.com/questions/9468435/look-how-to-fix-column-calculation-in-python-readline-if-use-color-prompt
Readline uses the characters \x01 and \x02 to mark invisible portions of the
prompt, so I am now pre-processing the prompt with this function:
def surround_ansi_escapes(prompt, start = \x01, end = \x02):
escaped = False
result =
for c in prompt:
if c == \x1b and not escaped:
result += start + c
escaped = True
elif c.isalpha() and escaped:
result += c + end
escaped = False
else:
result += c
return result
However, in my opionion this fact deserves at least to be mentioned in the
readline documentation.

[issue10967] move regrtest over to using more unittest infrastructure
R. David Murray added the comment: We have previously discussed adding resource-awareness to unittest, but that is a much bigger project (API design, scope considerations, etc etc). In the meantime, what we could do is modify the current resource-skip logic slightly: make it so that tests are *not* skipped for resource reasons *unless* some flag in support is set indicating that resource enforcement is in effect *and* the specified resource is not in the list of currently-asserted resources. That way tests are only skipped for resource reasons if run via regrtest. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10967 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue10967] move regrtest over to using more unittest infrastructure
Ezio Melotti added the comment:
There are actually three separate issues here:
1) The resources don't use unittest skip (or at least not always), so while
running the tests without regrtests there are no indication that some tests
have been skipped. This could be addressed by converting the current resources
to proper skips (with something like @skip_unless_resource('network')) and
shouldn't be too difficult.
2) The network resource could be enabled by default, given that network
connectivity is nowadays fairly common (it would be even better if that was
detected automatically at runtime). This would enable more tests and shouldn't
have negative side-effects (unless the network is not available and the tests
have no way to realize that and fail).
3) unittest could have a resource API, but that's not strictly necessary if
we still provide a way to run the skipped tests through regrtest and/or while
running the test file individually.

[issue17338] Add length_hint parameter to list, dict, set constructors to allow efficient presizing

The semantics would be basically: the list has behavior identical to if you hadn't provided length_hint, except the VM is free to preallocate efficiently.

If you *also* want a way to skip tests based on resource when running them outside regrtest, then unittest would have to grow a resource API. This can already be done though -- adding a resource API to unittest would just provide an additional way to do it without going through regrtest. I don't think we will ever get rid of regrtest. It would be nice if most of the code could be removed and standard unittest features were used instead, but regrtest will always have more advanced/customized feature built on top of unittest (which is not to say that a resource API for unittest is useless, but that's not a blocker for this issue :). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10967 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

There's also the issue that the unittest API is already quite big, and adding even more things there might do more harm than good. There are several other parts of regrtest that can take advantage of already existing unittest features first, and convert them might be enough to close this issue even if the existing resource infrastructure is kept in regrtest. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10967 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Mark Dickinson added the comment: This is not easy to avoid, I'm afraid, and it's a consequence of Python's usual rules for mixed-type arithmetic: (-0-0j) is interpreted as 0 - (0.0 + 0.0j) --- that is, the 0j is promoted to a complex instance (by giving it zero real part) before the subtraction is performed. Then the real part of the result is computed as 0.0 - 0.0, which is 0.0. Note that the first 0.0 comes from converting the *integer* 0 to a complex number.

[issue17338] Add length_hint parameter to list, dict, set constructors to allow efficient presizing
Raymond Hettinger added the comment: Guido has previously rejected any kind of user specified presizing parameter for dictionaries. He felt that it was breaking the abstraction in a way that caused people to focus on implementation specific details. Also, set() and dict() use presizing (and hash value reuse) only in the limited case of the input iterable being an exact dictionary or set. Otherwise, it makes no assumptions about the input iterable and grows as needed. For sets, even when the __len__ is known for a general iterable, we don't know how many unique elements are the input -- consider for example: set([None] * 100). In typical use cases for sets, a user also doesn't know in advance how many unique elements will be present -- and to the extent they try to add estimation logic, it would only complicate their programs. -- nosy: +rhettinger ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17338 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue17330] Stop checking for directory cache invalidation in importlib
Brett Cannon added the comment: So Nick Coghlan pointed out that this would require a deprecation warning which is doable using ImportWarning. But that also lowers my motivation to bother since there is no performance benefit. I will, though, at least make it clearer in the What's New doc and in the importlib docs that it is more of a need than an optional thing to do. -- assignee: - brett.cannon nosy: +ncoghlan ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17330 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
