Eli Bendersky eli...@gmail.com added the comment: Would it be clearer if we replaced the literal with a name? These C functions are called “type methods” to distinguish them from - things like [].append (which we call “object methods”). + methods bound to specific instances (things like sys.path.append), + which we call “object methods”. No, I don't think this is the intention (bound vs. unbound). I think the distinction is between special methods recognized by Python, and plain object methods defined by the user.

[issue12740] Add struct.Struct.nmemb
New submission from Stefan Krah stefan-use...@bytereef.org:
It is somewhat complicated to calculate the number of members in
a Struct, so I propose to add Struct.nmemb (in 3.3, 3.2 and 2.7):
import struct
s = struct.Struct(Pxx3L3s)
s.size
47
s.nmemb
5
I chose 'nmemb' because it is a standard name in Unix man pages.
Another option would be to spell it out ('nmembers').

[issue12741] Implementation of shutil.move
New submission from David Townshend aquavita...@gmail.com:
The shutil.move function uses os.rename to move files on the same file system.
On unix, this function will overwrite an existing destination, so the obvious
approach is
if not os.path.exists(dst):
shutil.move(src, dst)
But this could result in race conditions if dst is created after os.path.exists
and before shutil.move. From my research, it seems that this is a limitation
in the unix c library, but it should be possible to avoid it through a
workaround (pieced together from
http://bytes.com/topic/python/answers/555794-safely-renaming-file-without-overwriting
). This involves some fairly low-level work, so I propose adding a new move2
function to shutil, which raises an error if dst exists and locking it if it
doesn't:
def move2(src, dst):
try:
fd = os.open(dst, os.O_EXCL | os.O_CREAT)
except OSError:
raise Error('Destination exists')
try:
move(src, dst)
finally:
os.close(fd)
This could be optimised by using shutil.move code rather than just calling it,
but the idea is that an attempt is made to create dst with exclusive access. If
this fails, then it means that the file exists, but if it passes, then dst is
locked so no other process can create it.
As suggested on the mailing list
(http://mail.python.org/pipermail/python-ideas/2011-August/011132.html), an
alternative is to add this behaviour as an argument to shutil.move, which may
be a neater solution.
I will work on a patch for this and try to submit it in the next few days.

In more recent shutil development, arguments like copy_function and ignore (on copytree) were added to let people customize behavior without rewriting all the function logic.

[issue12726] explain that locale.getlocale() does not read system's locales
Terry J. Reedy tjre...@udel.edu added the comment:
Our docs explain behavior without, generally, explaining why. Hence the title
change.
'Returns the current setting for the given locale category' seems pretty clear
that it returns the current program setting rather than the default system
setting. However, 'program' could be added to be clearer.
The previous discussion for locale.getdefaultlocale makes it clear that the
starting program locale is (should be) the portable 'C' locale. I presume you
are saying that in this locale, the setting for the default LC_CTYPE category
is (None,None). However, this appears to currently only be true for 2.7. So I
suppose we could add for 2.7 In the starting 'C' locale, the LC_CTYPE setting
is (None,None). (Given the next paragraph describing 'C' as a non-standard
language code, I would have expected ('C',None), but it is as it is.)
Reading #6203, something different is needed for 3.2 and something else again
might be needed for 3.3 depending on what is or is not done.

[issue12728] Python re lib fails case insensitive matches on Unicode data
Tom Christiansen tchr...@perl.com added the comment: Terry J. Reedy tjre...@udel.edu added the comment: I am not sure that everyone will agree that this is a bug, rather than a fe= ature request, or that if a bug, that it should be changed in existing rele= ases and possibly break running code. The doc just says, somewhat vaguely, = that IGNORECASE works for Unicode characters as expected. I have added ot= hers as nosy for their opinions. Working as expected for Unicode characters means it must the Unicode's rules for casefolding. Otherwise you don't have Unicode at all; you just have ISO 10646. Unicode is not merely a larger character repertoire; again, that is merely ISO 10646. Unicode is all about the rules for processing this larger repertoire. This is a very common mistake, so common that it is in the Unicode FAQ: Q: What is the relation between ISO/IEC 10646 and Unicode? A: In 1991, the ISO Working Group responsible for ISO/IEC 10646 (JTC 1/SC 2/WG 2) and the Unicode Consortium decided to create one universal standard for coding multilingual text. Since then, the ISO 10646 Working Group (SC 2/WG 2) and the Unicode Consortium have worked together very closely to extend the standard and to keep their respective versions synchronized. [EH] Q: So are they the same thing? A: No. Although the character codes and encoding forms are synchronized between Unicode and ISO/IEC 10646, the Unicode Standard imposes additional constraints on implementations to ensure that they treat characters uniformly across platforms and applications. To this end, it supplies an extensive set of functional character specifications, character data, algorithms and substantial background material that is *not* in ISO/IEC 10646. http://unicode.org/faq/unicode_iso.html Part of those functional character specifications can be found in the three casefolding fields of the file UnicodeData.txt and also in two auxiliary files of the Unicode distribution, CaseFolding.txt and SpecialCasing.txt. The Unicode Character Database is not optional. If you do not use it, you do not have Unicode; instead you merely have ISO 10646, which is of zero practical use to anyone compared with Unicode. I'm sure that Python would not want to be stuck having something of no use to anyone when everyone else actually supports Unicode. One is not allowed to make up one's own rules that run counter to Unicode's and still make the claim that one is working on Unicode, since that is in fact not what one is doing. Based on all that, Python does not do case insensitive matching on Unicode, a condition contrary to its documented claims. That clearly makes it a bug that needs fixing rather than a feature request to be summarily ignored. The test file should have omitted the gratuitous and distracting warnings, = especially the one that effectively scolds Windows users for running Window= s. With those omitted, the test cases given would form the basis for an add= ed TestCase. I have absolutely no idea what on earth you could possibly be referring to. Honestly. I ran my tests on both releases (2.7 and 3.2), on both builds (wide and narrow), and on both platforms (Unix and Mac). The warnings are in there so I can make sure I have everything set up correctly to run the tests, and will understand why I get more failures than expected in the event that things are not set up appropriately. Let me make perfectly clear that I have never in my life come anywhere near a Microsoft system, let alone touched one, and that I furthermore never shall. I have not the foggiest notion what in the world you are complaining about. If the problem is that you are for some reason unable to create a Python with full Unicode support under Microsoft, that is hardly my fault. Render unto Caesar that which is Caesar's: complain to Microsoft about Microsoft's bugs, not to me, as I am wholly blameless of their problems. If you don't like my test cases, you know where to find vi. I supposed I could always send you the program that writes these programs for me, but as I knew you won't like it, I withheld it.

[issue12730] Python's casemapping functions are untrustworthy due to narrow/wide build issues
Terry J. Reedy tjre...@udel.edu added the comment: I agree that better masking of narrow-wide build difference would be good as long as it does not severely impact normal performance. Revision of the test file (see below) shows that the 'bug' is that the .upper, .lower, and .title methods leaves the tested non-BMP chars unchanged on narrow builds. I am not sure if this is true of all upper-plane chars and whether this is by design or simply a matter of not catching up to an ever-expanding database. Hence, I am also not sure whether this is a bug report or feature request. I made several changes in casemap.python so I could run it and get better information: * Rename to casemap.py. Many of us use software that recognizes and special-cases the standard .py extension. All python code files uploaded should use this. * Remove the unused 3-rd party regex import which stops the test for most people. * Remove the unnecessary PYTHONIOENCODING exit which stop the test on Windows and possibly elsewhere. The file seems to run fine without it. * Rewrite the test data using \U (8 hex chars) escapes for the non-BMP chars. That will be required for new tests for test_unicode.py. (I believe the test suite avoid literal non-ascii chars unless really necessary.) Besides which, all I see (on Windowsj) in Firefox is things like ð¼ð¯ð‘…ð¨ð‘‰ð¯ð». IDLE just has empty boxes. * Factor the tests so the output is easier to rewrite. * Rewrite the test output to make comparisons easier. Writing the 'wrong' answer first, directly under the original, made it easy to see that the 'wrong' answer *is* the original, unchanged. The revised version (to be uploaded separately) has the same 6 failures. -- nosy: +haypo, lemburg, loewis, terry.reedy stage: - needs patch versions: +Python 3.2, Python 3.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12730 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

If I understand, you are saying that this statement in the doc, Matches Unicode word characters; is not now correct and should be revised. Was it once correct? Could we add by an older definition of 'word' character? There has been some discussion of adding regex to the stdlib, possibly as a replacement for re. You posts indicate that regex is more improved then some realized, and hence has more incompatibilities that we realized, and hence is less suitable as a strictly backwards-compatible replacement. So I think it needs to be looked at as a parallel addition.

No, it currently does not. One would have to ask Matthew directly, but I believe it was because he was trying to stay compatible with re, sometimes apparently even if that means being bug compatible. I have brought it to his attention though, and at last report he was pondering the matter. In contrast to how Python behaves on narrow builds, even though Java uses UTF-16 for its internal representation of strings, its Java Pattern is quite adamant about treating with logical code points alone. Besides running afoul of tr18, it is senseless to do otherwise. A dot is one Unicode code point, no matter whether you have 8-bit code units, 16-bit code units, or 32-bit code units. Similarly, character classes and their negations only match entire code points, never pieces of the same. ICU's regexes work the same way the normal Java Pattern library does. So too do Perl, Ruby, and Go. Python is really the odd man out here. Almost. One interesting counterexample is the vim editor. It has dot match a complete grapheme no matter how many code points that requires, because we're dealing with user-visible characters now, not programmer-visible one. It is an unreasonable burden to make the programmer deal with the fine-grained details of low-level serialization schemes instead of at least(*) the code point level of operations, which is the minimum for getting real work done. (*Note that tr18 admits that accessing text at the code point level meets only programmer expectations, not those of the user, and therefore to meet user expectations much more elaborate patterns must necessarily be constructed than if logical groups of coarser granularity than code points alone are supported.) Python should not be subject to changing its behavior from one build to the next. This astonishing narrow-vs-wide build behavior makes it virtually impossible to write portable code to work on arbitrary Unicode text. You cannot even know whether you need to match one dot or two to get a single code point, and similarly for character indexing, etc. Even identifiers come into play. Surrogates should be utterly nonexistent/invisible at this, the normal level of operation. An API that minimally but uniformly deals with logical code points and nothing finer in granularity is the only way to go here. Please trust me on this one. Graphemes (tr18 Level 2) and collation elements (Level 3) will someday build on that, but one must first support code points properly. That's why it's a Level 1 requirement. --tom -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12729 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue12732] Can't portably use Unicode in Python identifiers
Terry J. Reedy tjre...@udel.edu added the comment: Ouch! Do the rejected characters qualify as identifier characters as defined in Reference 2.3 Identifiers and keywords? http://docs.python.org/py3k/reference/lexical_analysis.html#identifiers If some interpreter version accepts extra characters, beyond the definition (as happened in 2.x), it is not a bug for for another version to only accept what is defined. Side question: That section has A non-normative HTML file listing all valid identifier characters for Unicode 4.1 can be found at http://www.dcl.hpi.uni-potsdam.de/home/loewis/table-3131.html.; Is the set of identifier characters now larger, and if so, has the table been enlarged? -- nosy: +haypo, lemburg, loewis, terry.reedy stage: - needs patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12732 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue9723] Add shlex.quote
Ezio Melotti ezio.melo...@gmail.com added the comment:
-_find_unsafe = re.compile(r'[^\w\d@%_\-\+=:,\./]').search
+_find_unsafe = re.compile(r'[^\w@%\-\+=:,\./]', re.ASCII).search
FWIW there are still unnecessary escapes before '+' and '.', and possibly '-'
('-' doesn't need escaping only when it's at the end (or beginning) of the
regex).

[issue12672] Some problems in documentation extending/newtypes.html
Eric Snow ericsnowcurren...@gmail.com added the comment: Eli, I interpreted it the same way you did. In the doc, type methods are those that map directly to PyTypeObject. Any custom type methods go in tp_methods. You could almost call the former PyTypeObject methods rather than type methods. And both are distinct from functions/methods in a type's __dict__... Also I agree that the object methods statement is unnecessary. -- nosy: +ericsnow ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12672 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue12731] python lib re uses obsolete sense of \w in full violation of UTS#18 RL1.2a
Tom Christiansen tchr...@perl.com added the comment:
Terry J. Reedy tjre...@udel.edu added the comment:
However desireable it would be, I do not believe there is any claim in the =
manual that the re module follows the evolving Unicode consortium r.e. stan=
My from the hip thought is that if re cannot be fixed to follow
the Unicode Standard, it should be deprecated in favor of code
that can if such is available, because you cannot process Unicode
text with regular expressions otherwise.
dard. If I understand, you are saying that this statement in the doc, Matc=
hes Unicode word characters; is not now correct and should be revised. Was=
it once correct? Could we add by an older definition of 'word' character=
?
Yes, your hunch is exactly correct. They once had a lesser definition that
they have now. It is very very old. I had to track this down for Java
once. There is some discussion of a word_character class at least
as far back as tr18v3 from back in 1998.
http://www.unicode.org/reports/tr18/tr18-3.html
By the time tr18v5 rolled around just a year later in 1999, the overall
document has changed substantially, and you can clearly see its current
shape there. Word characters are supposed to include all code points with
the Alphabetic property, for example.
http://www.unicode.org/reports/tr18/tr18-5.html
However, the word alphabetic has *never* been synonymous in
Unicode with
\p{gc=Lu}
\p{gc=Ll}
\p{gc=Lt}
\p{gc=Lm}
\p{gc=Lo}
as many people incorrectly assume, nor certainly to
\p{gc=Lu}
\p{gc=Ll}
\p{gc=Lt}
let alone to
\p{gc=Lu}
\p{gc=Ll}
Rather, it has since its creation included code points that are not
letters, such as all GC=Nl and also certain GC=So code points. And,
notoriously, U+0345. Indeed it is here I first noticed that that Python had
already broken with the Standard, because U+0345 COMBINING GREEK
YPOGEGRAMMENI is GC=Mn, but Alphabetic=True, yet I have shown that
Python's title method is messing up there.
I wouldn't spend too much in archaeological digs, though, because lots of
stuff has changed since the less millennium. It was in tr18v7 from 2003-05
that we hit paydirt, because this is when the famous Annex C of RL1.2a
fame first appeared:
http://www.unicode.org/reports/tr18/tr18-7.html#Compatibility_Properties
Notice how it defines \w to be nothing more than \p{alpha}, \p{digit}, and
\p{gc=Pc}. It does not yet contain the requirement that all Marks be
counted as part of the word, just the few that are alphas -- which the
U+0345 counts for, since it has an uppercase map of a capital iota!
That particular change did not occur until tr18v8 in 2003-08, barely
a scant three months later.
http://www.unicode.org/reports/tr18/tr18-8.html#Compatibility_Properties
Now at last we see word characters defined in the modern way that we
have become used to. They must match any of:
\p{alpha}
\p{gc=Mark}
\p{digit}
\p{gc=Connector_Punctuation}
BTW, Python is matching all of
\p{GC=N}
meaning
\p{GC=Nd}
\p{GC=Nl}
\p{GC=No}
instead of the required
\p{GC=Nd}
which is a synonym for \p{digit}.
I don't know had that happened, because \w has never included
all number code points in Unicode, only the decimal number ones.
That all goes to show why, when citing conformance to some aspect of
The Unicode Standard, one must be exceedingly careful just how one
does so!
The Unicode Consortium recognizes this is an issue, and I am pretty
sure I can hear it in your own subtext as well.
Kindly bear with and forgive me for momentarily sounding like a standard
lawyer. I do this because to show not just why it is important to get
references to the Unicode Standard correct, but indeed, how to do so.
After I have given the formal requirements, I will then produce
illustrations of various purported claims, some of which meet the
citation requirements, and others which do not.
===
To begin with, there is an entire technical report on conformance.
It includes:
http://unicode.org/reports/tr33/
The Unicode Standard [Unicode] is a very large and complex standard.
Because of this complexity, and because of the nature and role of the
standard, it is often rather difficult to determine, in any particular
case, just exactly what conformance to the Unicode Standard means.
...
Conformance claims must be specific to versions of the Unicode
Standard, but the level of specificity needed for a claim may vary
according to the nature of the particular conformance claim. Some
standards developed by the Unicode Consortium require separate
conformance to a specific version (or later), of the Unicode Standard.
This version is sometimes called the base version. In such cases, the
version of the standard and the version of the Unicode Standard to

Re: [issue10087] HTML calendar is broken
Hello Éric, I might have ignored some minor stylistic comments. The '.' in the help text and , after the last TestName, I am not sure if it is of concern. I think, to update the stylistic comments, if the submitters (if they care) could have updated the patch, or a separate commit on style changes can be done (if they are worth it). And yeah, it is bad to ignore substantiative comments. I hope, I did not overlook any. Ezio's main point was he was worried about using sys.stdout.buffer (as I was too) and we got that clarified.
