[issue21547] '!s' formatting documentation bug
New submission from Joshua Landau: In the docs for 2.x about the formatting syntax: https://docs.python.org/2/library/string.html#format-string-syntax it says Two conversion flags are currently supported: '!s' which calls str() on the value, and '!r' which calls repr(). but for unicode formatters, '!s' calls unicode() instead. See http://stackoverflow.com/questions/23773816/why-python-str-format-doesnt-call-str for the question that found this. -- assignee: docs@python components: Documentation messages: 218863 nosy: Joshua.Landau, docs@python priority: normal severity: normal status: open title: '!s' formatting documentation bug versions: Python 2.7 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21547 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue21549] Add the members parameter for TarFile.list()
New submission from Serhiy Storchaka: The proposed patch adds the members parameter for TarFile.list() with the same meaning as in TarFile.extractall(). This is needed for implementing the tar command utility which allows filtering and transforming an output (e.g. output numerical ids instead names for owner/group). An alternative approach is to add the filter parameter (as in TarFile.add()) to both TarFile.list() and TarFile.extractall(). -- components: Library (Lib) files: tarfile_list_members.patch keywords: patch messages: 218866 nosy: lars.gustaebel, serhiy.storchaka priority: normal severity: normal stage: patch review status: open title: Add the members parameter for TarFile.list() type: enhancement versions: Python 3.5 Added file: http://bugs.python.org/file35307/tarfile_list_members.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21549 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

New submission from Serhiy Storchaka: Here is preliminary Python implementation of the tar archiving utility. I propose to add it to Tools/script. The main purpose of this the research of which features needed the tarfile module. Another purpose is that this provides more powerful tool to create or extract tar archives on platforms where the tar utility is not installed (the tarfile module itself provides very simple command line interface). Supported options are mainly common subset of GNU tar and bsdtar options. Some options (--absolute-names, controlling of symlinks and hardlings dereferencing and files overwriting) needs implementing new features in the tarfile module. -- components: Demos and Tools files: tar.py messages: 218867 nosy: berker.peksag, lars.gustaebel, serhiy.storchaka priority: normal severity: normal stage: test needed status: open title: Add Python implementation of the tar utility type: enhancement versions: Python 3.5 Added file: http://bugs.python.org/file35308/tar.py ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21550 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue21542] pprint doesn't work well for counters, sometimes shows them like a dict
akira added the comment:
If it fits on a line then it seems Counter's repr is used:
pprint(Counter({i:i*i for i in range(10)}))
Counter({9: 81, 8: 64, 7: 49, 6: 36, 5: 25, 4: 16, 3: 9, 2: 4, 1: 1, 0: 0})
Otherwise It is shown as a dict (Counter is a dict subclass) if it is too
large (multi-line):
pprint(Counter({i:i*i for i in range(10)}), width=20)
{0: 0,
1: 1,
2: 4,
3: 9,
4: 16,
5: 25,
6: 36,
7: 49,
8: 64,
9: 81}
the behaviour is weird but pprint doesn't promise that custom objects such
as Counter that can't be created using Python literals will be printed in a
reversible manner.
It seems there is a special support for some objects:
pprint(frozenset({i for i in range(10)}))
frozenset({0, 1, 2, 3, 4, 5, 6, 7, 8, 9})
pprint(frozenset({i for i in range(10)}), width=20)
frozenset({0,
1,
2,
3,
4,
5,
6,
7,
8,
9})
Perhaps the support for Counter could be added using functools.singledispatch
and/or __prettyprint__ hook from issue #7434

[issue21551] Behavior of word boundaries in regexes unexpected
New submission from Wellington Fan:
Hello,
It seems that the word boundary sequence -- r'\b' -- is not behaving as
expected using re.split(). The regex docs say:
\b Matches the empty string, but only at the start or end of a word.
My (failing) test:
import re
re.split(r'\b', 'A funky string')
['A funky string']
We get a one-element array returned; I would expect a seven-element array:
['', 'A', ' ', 'funky', ' ', 'string', '']
I have equivalent code in PHP that *does* work:
php print_r( preg_split('/\b/', 'A funny string') );
Array
(
[0] =
[1] = A
[2] =
[3] = funny
[4] =
[5] = string
[6] =
)

[issue20035] Clean up Tcl library discovery in Tkinter on Windows
Serhiy Storchaka added the comment: I want to get this too, but perhaps there are some issues in a code. 1. Py_GetPrefix() returns wchar_t* string with maximal length MAXPATHLEN (defined in Include/osdefs.h as 256 on Windows). Then wcstombs() converts it to char* string. Are you sure that MAX_PATH (defined as 260 on Windows) is enough for converted string? I afraid that for multi-byte encoding it can be 2*MAXPATHLEN or even 3*MAXPATHLEN bytes. 2. After converting _tcl_library contains a path in locale encoding. And _putenv() works with it. I'm not sure, but I afraid that Tcl_SetVar() can expect UTF-8 encoded string.

[issue21547] '!s' formatting documentation bug
Steven Barker added the comment:
The behavior of !s with the format() methods isn't exactly the same as %s with
% formatting. With the latter, the conversion depends on the type of the result
string, which in turn depends on whether the format string *or any of the
values values* is unicode:
class X():
def __str__(self): return str
def __unicode__(self): return uunicode
%s %s % (foo, X())
'foo str'
%s %s % (ufoo, X())
u'foo unicode'
u%s %s % (foo, X())
u'foo unicode'
u%s %s % (ufoo, X())
u'foo unicode'
The format methods are more consistent, always returning the same type as the
format string regardless of the types of the arguments (and using the
appropriate converter):
{} {!s}.format(foo, X())
'foo str'
{} {!s}.format(ufoo, X())
'foo str'
u{} {!s}.format(foo, X())
u'foo unicode'
u{} {!s}.format(ufoo, X())
u'foo unicode'
The documentation for %s conversion (in the second table here:
https://docs.python.org/2/library/stdtypes.html#string-formatting-operations )
also suggests that it always uses str(), though the footnote for that table
entry alludes to the behavior shown above without ever mentioning using
unicode() for conversions explicitly.

[issue2506] Add mechanism to disable optimizations

Do you really need to disable constant folding and other transformations? * Have you explored whether the peephole.c code can be changed to indicate the continue-statement was visited? * Why does this have to be a command-line setting rather than a flag or environment variable settable by coverage.py? * Is there some less radical way the coverage.py can be taught to make the continue-statement as visited? * Are you requesting that optimization constraints be placed on all of the implementations of Python (Jython, PyPy, and IronPython) to make coverage.py perfect? * Do you want to place limits on what can be done by Victor's proposed AST tranformations which will occur upstream from the peepholer and will make higher level semantically-neutral transformations *prior* to code generation. * Have you considered whether the genererated PYC files need a different magic number or some other way to indicate that they aren't production code? * If coverage.py produces a report on different code than the production run, doesn't that undermine some of the confidence the meaningfulness of the report? In other words, are you sure that you're making the right request and that it is really worth it?
