[issue10943] abitype: Need better support to port C extension modules to the stable C API
New submission from Leo fhaxbo...@googlemail.com: I tried to port the extension module at http://code.google.com/p/pyhyphen/source/browse/3.x/hnjmodule.c to the stable C API using abitype.py. I gave up after the following exceptions: - execption raised for missing PyVarObject_HEAD: this could be rixed by deleting a /* */ comment before. I think abitype.py should properly skip comments rather than forcing the user to delete them. - the xxxmodule.c on which hnjmodule.c is based, defines a PyObject Str_type wherr tp_basicsize is 0 rather than sizeof(XXX). This causes abitype.py to raise a key error as '0' seems to be ignored by abitype.py. Finally, I suggest to add to the source tree a boiler plate C module conforming to the stable API such as xxxmodule-stable-api.c. This would help creating extensions from scratch. -- components: Extension Modules messages: 126519 nosy: fhaxbo...@googlemail.com priority: normal severity: normal status: open title: abitype: Need better support to port C extension modules to the stable C API type: feature request versions: Python 3.2 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10943 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue10947] imaplib: Internaldate2tuple and ParseFlags require (and latter returns) bytes arrays; should allow/return str
New submission from Joe Peterson j...@skyrush.com: In imaplib, there is currently a mix of bytes array and str use. Time2Internaldate(), e.g., returns (and accepts) str. Internaldate2tuple() and ParseFlags() only accept a bytes object, and the latter returns a tuple of bytes objects. Of course, these were all strings in Python 2. To regain compatibility with Python 2 behavior and make things more consistent, this patch changes the return type of ParseFlags() to a str tuple, and allow it and Internaldate2tuple() to accept either a bytes object or a str. The unit test has been expanded to test these. Note that applying this patch assumes that the the patches from issue 10939 and issue 10941 have been applied. Also, I am not sure it is proper to accept *both* bytes array and str. Perhaps only str should be allowed.

[issue10935] wsgiref.handlers.BaseHandler and subclasses of str
Phillip J. Eby p...@telecommunity.com added the comment: Doesn't matter how unpythonic it is: the spec calls for exact types and has done so for six years already, so it's a bit late to do anything about it. (And any version of Python that allowed string subclasses was in violation of the spec and therefore buggy.) In principle, this class could allow non-str objects if and ONLY if they were converted to actual str objects upon receipt -- but they would have to be the *exact* type after this conversion. If somebody wants to implement that, I have no objection. But it MUST reject non-basestring input values and values that don't convert to an exact type str. (IOW, type(str(x)) is str must hold.) To put it another way, the WSGI protocol requires output headers to be of type 'list' where all elements are type 'tuple' and containing two 'str' entries. The Headers class cannot fulfill this contract if it allows non-conforming input. So non-conforming input must either be rejected or made to conform. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10935 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue10948] Trouble with dir_util created dir cache
New submission from Diego Queiroz queiroz.di...@gmail.com: There is a problem with dir_util cache (defined by _path_created global variable). It appears to be useful but it isn't, just repeat these steps to understand the problem I'm facing: 1) Use mkpath to create any path (eg. /home/user/a/b/c) 2) Open the terminal and manually delete the directory /home/user/a and its contents 3) Try to create /home/user/a/b/c again using mkpath Expected behavior: mkpath should create the folder tree again. What happens: Nothing, mkpath thinks the folder already exists because its creation was cached. Moreover, if you try to create one more folder level (eg. /home/user/a/b/c/d) it raises an exception because it thinks that part of the tree was already created and fails to create the last folder. I'm working with parallel applications that deal with files asynchronously, this problem gave me a headache. Anyway, the solution is easy: remove the cache. -- assignee: tarek components: Distutils messages: 126540 nosy: diegoqueiroz, eric.araujo, tarek priority: normal severity: normal status: open title: Trouble with dir_util created dir cache type: behavior versions: Python 2.5, Python 2.6, Python 2.7, Python 3.1 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10948 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue10932] distutils.core.setup - data_files misbehaviour ?
Éric Araujo mer...@netwok.org added the comment:
Thanks for the report.
“No directory information from files is used to determine the final location of
the installed file; only the name of the file is used”
I understand this line to mean that only the basename of the file will be used
in the target directory, IOW that ('config', ['cfg/data.cfg']) will create a
file in config/data.cfg, not config/cfg/data.cfg. I’m not 100% sure about my
reading though, this line is confusing.
Paths starting with '..' are relative, even if they’re not under the top-level
directory of the project (do the docs say they should be?), so the ability to
give '../../spam/whatever' as data file looks okay. However, it should not be
installed to target_dir/../../spam, that’s definitely a bug (coming from
os.path.join in cmd.Command.copy_file, I think).
If you want to write a test and fix, there are some guidelines at

[issue10923] Python 2.7 hangs on Unicode+threading
Amaury Forgeot d'Arc amaur...@gmail.com added the comment:
import child_directory
Then it's certainly an effect of the import lock:
http://docs.python.org/library/threading.html#importing-in-threaded-code
In your case, the first call to encode('utf8') indirectly imports utf8.py,
while the import lock is held by 'import child_directory'.
Then the self.loglock is the second resource that closes the deadlock loop.
A workaround is to add some call to encode('utf8') before the thread is created.

[issue10948] Trouble with dir_util created dir cache
Diego Queiroz queiroz.di...@gmail.com added the comment: Well. My application does not actually randomly remove the folders, it just can't guarantee for a given process how the folder it created will be deleted. I have many tasks running on a cluster using the same disk. Some tasks creates the folders/files and some of them remove them after processing. What each task will do depends of the availability of computational resources. The application is also aware of possible user interaction, that is, I need to be able to manipulate folders manually (adding or removing) without crashing the application or corrupting data. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10948 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue10950] ServerProxy returns bad XML
New submission from Beau beaumarti...@gmail.com:
xmlrpc.client.ServerProxy calls that return XML (ie, the a non-marshallable
type) give bad XML, with \ (backslash then double quote characters, '\\'; not
escaped double quote) in place of , and \' in place of '. Ampersands aren't
XML-escaped either.
(I have only tested this with Last.fm's API but I have made calls that return
marshallable types with no problem, so I'm assuming the issue lies with
ServerProxy and not Last.fm's XML-RPC servers.)
The following test code, identical to that in the attached file illustrates the
bug; it throws an xml.parsers.expat.ExpatError as the XML is bad:
# Get a Last.fm user's library.
# http://www.last.fm/api/show?service=323
import xmlrpc.client
import xml.etree
server = xmlrpc.client.ServerProxy('http://ws.audioscrobbler.com/2.0/')
parameters = {'api_key': 'b25b959554ed76058ac220b7b2e0a026', 'user':
'joanofarctan', 'page': 1}
tracks = server.library.getTracks(parameters)
tracks_xml = xml.etree.ElementTree.parse(tracks)
# Should get xml.parsers.expat.ExpatError: XML declaration not well-formed:
line 1, column 14.
# (Line 1, column 14 is a backslash: ?xml version=\1.0\
encoding=\utf-8\?.)

[issue10948] Trouble with dir_util created dir cache
Diego Queiroz queiroz.di...@gmail.com added the comment: Suppose the application creates one folder and add some data to it: - /scratch/a/b/c While the application is still running (it is not using the folder anymore), you see the data, copy it to somewhere and delete everything manually using the terminal. After some time, (maybe a week or a month later, it doesn't really matter) the application wants to write again on that folder, but ops, the folder was removed. As application is very well coded :-), it checks for that folder and note that it doesn't exist anymore and needs to be recreated. But, when the application try to do so, nothing happens, because the cache is not updated. ;/ Maybe distutils package was not designed for the purpose I am using it (I am not using it to install python modules or anything), but this behavior is not well documented anyway. If you really think the cache is important, two things need to be done: 1) Implement a way to update/clear the cache 2) Include details about the cache and its implications on distutils documentation -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10948 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue10935] wsgiref.handlers.BaseHandler and subclasses of str
Phillip J. Eby p...@telecommunity.com added the comment: One of the original reasons was to make it easier for server authors writing C code to interface with WSGI. C APIs that operate on lists and dicts often do not do what you would expect, when called on a subclass. Essentially, this could lead to an app that appears to work correctly on one server, but breaks strangely when run on another. (IOW, Python's C API and built-in types often break the Liskov principle: there are C-level operations that don't call back into Python subclass methods, so overriding just a few methods usually doesn't work as expected.) Another reason was to avoid having to document precisely which methods of a str, list, etc. are required to be implemented. (This is somewhat easier now that we have abc's, but really, it's still a royal PITA.) In any event, it's entirely moot now, six years later. Any change requests should be sent to the Web-SIG for WSGI 2.0 discussion, as changing the existing PEPs is not an option. (Guido has pronounced that I cannot change PEP 333 in any way, so even if I agreed with the requests in this thread, there is simply no way that wsgiref is changing in 2.x. PEP has just been approved as well, so the odds of even a 3.x change are low. But as I said, I won't object to a Headers patch that *converts* its non-conforming inputs to objects of type str, as long as they were stringlike objects to start with.) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10935 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

There is no clear distinction between public and private functions in distutils, so I understand how you could find this seemingly useful function and use it in your code. The solution is to use a public function like os.makedirs.

[issue10950] ServerProxy returns bad XML
Georg Brandl ge...@python.org added the comment:
Not sure what you mean by non-marshallable type. The Last.fm API returns the
XML as an XMLRPC string, including the backslashes.
I tried the same call in Ruby using the script below, and get the backslashes
too. I would say this is a fault of Last.fm's XMLRPC server.
Ruby code:
require 'xmlrpc/client'
cl = XMLRPC::Client.new2 'http://ws.audioscrobbler.com/2.0/'
puts cl.call('library.getTracks', {'api_key' =
'b25b959554ed76058ac220b7b2e0a026', 'user' = 'joanofarctan', 'page' = 1})

[issue10948] Trouble with dir_util created dir cache
Diego Queiroz queiroz.di...@gmail.com added the comment: You were right, os.makedirs fits my needs. :-) Anyway, I still think the change in the documentation is needed. This is not an implementation detail, it is part of the way the function works. The user should be aware of the behavior when he call this function twice. In my opinion, the documentation should be clear about everything. We could call this an implementation detail iff it does not affect anything externally, but this is not the case (it affects subsequent calls). This function does exactly the same of os.makedirs but the why is discribed only in a comment inside the code. We know this is a poor programming style. This information need to be available in the documentation too. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10948 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

So is, conceptually, required_capacity, but it is defined as an int because it
is defined with XXXROUNDUP() and hence fancy_roundup(), which returns -1 if
n1-n_nchildren is so large that the smallest power of 2 larger is too big for
an int.
The comparison is 'OK' in context in that it is preceded by and guarded by
if (current_capacity 0 || required_capacity 0)
return E_OVERFLOW;
If I had written this, I might have thought about replacing all the comparisons
with one check of n1-n_nchildren against some reasonable limit calculated from
PY_SIZE_MAX / sizeof(node), and making both capacities unsigned.
---
Unused, Parser/parsetok.c, 130: local vars handling_with and handling_import
are both set to 0 both here and again on line 157 and not seen elsewhere in the
file. I presume both could just be deleted both places.
---
Empty body, pgen, multiple places: those I checked are appearances of the
REQN() macro. The REQ() macro did not generate a warning.
#ifdef Py_DEBUG
#define REQN(i, count) \
if (i count) { \
fprintf(stderr, REQNFMT, count); \
Py_FatalError(REQN); \
} else
#else
#define REQN(i, count) /* empty */
#endif
Since all invocations of REQN look like REQN(i, 1);, I presume the
'else' is there to swallow up the ';' which is added to make macro calls look
like statements with a function call. I guess this is a style issue. As I
remember, the suggestion to simply add '{}' to the macro would make syntax
errors.
---
Uninitialized, Objects/setobject.c, 2445, in test_c_api:
while (_PySet_NextEntry((PyObject *)dup, i, x, hash)) {
s = _PyUnicode_AsString(x);
I presume x is set by _PySet... . (If i and hash are also, they are not used).
So 'may be' but not actually.
---
Conclusion: the 'fix' is some real cleanup, some warning suppression.

[issue10952] Don't normalize module names to NFKC?
New submission from STINNER Victor victor.stin...@haypocalc.com: The Python 3 parser normalizes all identifiers using NFKC (as described in the PEP 3131). Examples: - U+00B5 (µ: Micro sign) is normalized to U+03BC (μ: Greek small letter mu) - U+FB03 (ffi: Latin small ligature ffi) is normalized to 'ffi' The problem is that it does also normalize module names, but not the filename. The module name in the Python source code is written with the keyboard (eg. U+00B5 in my case) and then normalized to NFKC (= U+03BC). The filename is also written using the keyboard (U+00B5), but it is never normalized. Attached script tests the current behaviour using µTorrent name with U+00B5 and U+03BC: import with U+00B5 or U+03BC use the filename with U+03BC. The problem is that I'm able to write 'µ' (U+00B5) with my keyboard, but not U+03BC (μ). -- components: Interpreter Core, Unicode files: module_name.py messages: 126577 nosy: haypo priority: normal severity: normal status: open title: Don't normalize module names to NFKC? versions: Python 3.1, Python 3.2, Python 3.3 Added file: http://bugs.python.org/file20459/module_name.py ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10952 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

STINNER Victor victor.stin...@haypocalc.com added the comment: µTorrent.py filename example comes from #10754. This issue is unrelated to the Python parser or the import machinery: it is a surprising behaviour of the MBCS codec which replaces unencodable characters to a similar glyph.

[issue10952] Don't normalize module names to NFKC?
Alexander Belopolsky belopol...@users.sourceforge.net added the comment:
This proposal makes sense because it would make
import µTorrent
behave the same as
µTorrent = __import__('µTorrent')
However, I think this is a feature request and a language change because the
current grammar is
import_stmt ::= import module ..
module ::= (identifier .)* identifier
and in order to implement the proposed feature, module will have to become a
separate AST node that won't be treated as identifier.

This won't be a problem if you make import \xB5Torrent behave as
\xB5Torrent = __import__('\xB5Torrent'). The latter is equivalent
to \u03BCTorrent = __import__('\xB5Torrent').

import name is compiled to IMPORT_NAME(name); STORE_NAME(name) bytecode
instructions. So you proposed to compile it to IMPORT_NAME(name);
STORE_NAME(normalized_name) if name is different than the normalized name. Ok,
I think that it is possible.

[issue10953] safely eval serialized dict/list data from arbitrary string over web with no side effects
New submission from kai zhu kai...@ugcs.caltech.edu:
rather than serialize python dicts list to json / xml / protocol buffer for
web use, its more efficient to just serialize w/ repr() then use eval(), if
only there was a way to guarantee arbitrary code can't b executed.
this is a very simple proposed method for the latter. b4 eval(), it compiles
string to python code object checks for:
1. co_names list can only contain 'False', 'None', 'True'
-this ensures no function call can b made
2. co_consts list cannot contain code objects
-embedded lambda's r forbidden.
3. grave accents are explicitly forbidden.
here is the code for both python2.5 (intended for google appengine) python 3k:
## safe_eval.py
import sys, types
if sys.version_info[0] == 2: ## py2x
_co_safe = 'co_argcount co_nlocals co_varnames co_filename co_freevars
co_cellvars'.split(' ')
else: ## py3k
_co_safe = 'co_argcount co_kwonlyargcount co_nlocals co_names co_varnames
co_filename co_freevars co_cellvars'.split(' ')
## safely eval string with no side-effects
def safe_eval(ss):
if not ss: return None
if '`' in ss: raise ValueError('grave accent ` forbidden')
cc = compile(ss, '', 'eval')
for aa in _co_safe:
if getattr(cc, aa): raise ValueError(aa + ' must be empty / none / zero')
for aa in cc.co_names:
if aa not in ['False', 'None', 'True']: raise ValueError('co_names can only
contain False, None, True')
for aa in cc.co_consts:
if isinstance(aa, types.CodeType): raise TypeError('code objects not
allowed in co_consts')
return eval(cc, {})

[issue10952] Don't normalize module names to NFKC?
Martin v. Löwis mar...@v.loewis.de added the comment: I think this issue falls into a similar category as support for case-insensitive but case-preserving file systems. Python uses regular file system lookups, but then may need to verify whether it got the right one. I'd like to request that PEP 3131 is followed as it stands: identifier lookup uses NFKC, period. This gives two issues: a) how can users make sure that they name the files correctly? and b) what if the file system implementation mangles file names. For b), I'd use the same approach as with case-insensitive lookups: verify that the file we read is really the one we want. For a), wrt. I'm not able to write U+03BC with my keyboard, I say tough luck - don't use that character in a module name, then. Somebody with a Greek keyboard will have no problems doing that. This is really the same as any other non-ASCII character which you are unable to type: it just means that you can't conveniently enter the respective Python identifier. Just try importing саша, for example.

docpatch for 3.x csv docs:
In the csv.writer docs, insert the sentence If csvfile is a file object, it
should be opened with newline=''. immediately after the sentence csvfile can
be any object with a write() method.
In the closely-following example, change the open call from open('eggs.csv',
'w') to open('eggs.csv', 'w', newline='').
In section 13.1.5 Examples, there are 2 reader cases and 1 writer case that
likewise need inserting , newline='' in the open call.
