[issue6472] Inconsistent use of iterator in ElementTree doc diff between Py and C modules
Milko Krachounov pyt...@milko.3mhz.net added the comment: This isn't just a documentation issue. A function named getiterator(), for which the docs say that it returns an iterator, should return an iterator, not just an iterable. They have different semantics and can't be used interchangeably, so the behaviour of getiterator() in ElementTree is wrong. I was using this in my program: iterator = element.getiterator() next(iterator) subelement = next(iterator) Which broke when I tried switching to ElementTree from cElementTree, even though the docs tell me that I'll get an iterator there. Also, for findall() and friends, is there any reason why we can't stick to either an iterator or list, and not both? The API will be more clear if findall() always returned a list, or always an iterator, regardless of the implementation. It is currently not clear what will happen if I do: for x in tree.findall(path): mutate_tree(tree, x) -- components: +Library (Lib) nosy: +milko.krachounov type: - behavior versions: +Python 2.6, Python 2.7 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue6472 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue7444] Allow for a default method in the JSON decoder
New submission from Daniel Goldman goldman.in...@gmail.com: I encountered JavaScript-style Date objects in a JSON document that I wanted to parse, and these objects were causing the Python JSON decoder to raise an error with a message that said Expecting object, followed by the line and column numbers. Here is an example of how such an object appeared in the document: someDate: new Date(120756820), I went looking in the documentation for a way to plug in a fall-back method, to be used when the module's standard conversion methods fail, but none of the supplied hooks seemed appropriate. It would be enormously helpful to provide a hook for such a method in the JSON decoder in a future release of Python. I believe this would parallel the JSON encoder's default keyword argument. In this way, developers could provide their own method of handling non-standard values in JSON documents. Ultimately, to parse the Date objects, I created a function similar to those in the json.decoder module, added the function to the json.decoder.ANYTHING list, and assigned a new Scanner object with this updated list to json.decoder.JSONScanner. I couldn't find a similar issue in the issues list, but my apologies if this has already been suggested. -- components: Library (Lib) messages: 95994 nosy: dhgoldman severity: normal status: open title: Allow for a default method in the JSON decoder type: feature request versions: Python 2.7, Python 3.2 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7444 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue7446] http.cookies.BaseCookie (and SimpleCookie) can't be load from dict
New submission from Thomas Courbon hart...@yahoo.fr:
Hi there !
According the documentation [1], the following code should work :
from http.cookies import SimpleCookie
c = SimpleCookie({'field1': 'value1', 'field2': 'value2'})
print(c)
'Set-Cookie: field1=value1\r\nSet-Cookie: field2=value2'
But an exception is raised :
Traceback (most recent call last):
File stdin, line 1, in module
File c:\python31\lib\http\cookies.py, line 507, in output
result.append( V.output(attrs, header) )
AttributeError: 'str' object has no attribute 'output'
in BaseCookie.load(...) the call to BaseCookie.update(rawdata) seem to
use dict.__setitem__ instead of BaseCookie.__setitem__.
Despite it's weird (I believe that the __setitem__ of the child class
should be used) I don't know why.
I don't have a solution to this underlying issue so I propose to define
an update method for BaseCookie:
def update(self, other=None, **kwargs):
if other is None:
other = kwargs
elif not hasattr(other, 'items'):
other = dict(other)
for k, v in other.items():
self[k] = v
This method behave like the dict one.
Hope it help and it's not a duplicate.
Regards,
Thomas

Andrew Svetlov andrew.svet...@gmail.com added the comment: You right, problem is not in os.unlink (Windows call DeleteFile) itself. I have TortoiseSVN (very popular Explorer extension to work with Subversion) installed. This tool run TSVNCache.exe process to update own data in background. TSVNCache.exe receive NotifyChangeDirectory events for svn checkout folders. support.TESTFN is tempfile name in current working directory. If I try to run unittests from some folder from python checkout TSVNCache.exe get change notify and analyze it. So, sometimes I can see race condition: - python: os.unlink(file) - TSVNCache.exe: get change event - TSVNCache.exe: query changes - python: open(file) - oops, TSVNCache.exe still processing notification and lock deleted file by holding opened handles to it. According to MSDN for DeleteFile function: The DeleteFile function marks a file for deletion on close. Therefore, the file deletion does not occur until the last handle to the file is closed. Subsequent calls to CreateFile to open the file fail with ERROR_ACCESS_DENIED. We get exactly same. - TSVNCache.exe finish of change update and release handle. File is actually deleted. I see this situation in sysinternals Process Monitor tool. Probability of race condition is tiny but non-zero.

[{'x': 300,
'y': 40,
'z': 50},
{'x': 60,
'y': 7000,
'z': 80}]
It would also be nice if pprint could accept arguments telling it how to
format various types:
pprint(s, width=15, format={int: '15,'})
[{'x': ' 30,000,000,000',
'y': ' 4,000,000,000',
'z': ' 5,000,000,000'},
{'x': ' 6,000,000,000',
'y': ' 70,000,000',
'z': ' 8,000,000,000'}]

[issue1578269] Add os.link() and os.symlink() and os.path.islink() support for Windows
Andrew Svetlov andrew.svet...@gmail.com added the comment: Jason, as I see you implemented os.samefile (actually ntpath.samefile) but os.sameopenfile is still not implemented. Looks like it's easy to do: while GetFinalPathNameByHandle already accept file handle you can use CRT function _get_osfhandle(fd) to convert file descriptors (arguments for sameopenfile) to file handles and pass it to GetFinalPathNameByHandle. For me samefile and sameopenfile has very close semantic and I like to see both if it's possible. Thanks. -- nosy: +asvetlov ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue1578269 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue5985] Implement os.path.samefile and os.path.sameopenfile on Windows
Andrew Svetlov andrew.svet...@gmail.com added the comment: Please note: patch for http://bugs.python.org/issue1578269 is already has implementation for samefile. It's easer to add sameopenfile is same way than maintain two different approaches. Unfortunately solution will work only starting from Windows Vista and Windows Server 2008. -- nosy: +asvetlov ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue5985 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue5949] IMAP4_SSL spin because of SSLSocket.suppress_ragged_eofs
Scott Dial sc...@scottdial.com added the comment: Alright, I am attaching a new patch to correct the brain-fart inefficiency of slicing versus endswith(). I don't understand why this is so difficult to review. I don't think Janssen is the right person to have been assigned to this. While it is related to SSL, I don't think the IMAP module is even on his radar. Whereas, I use this module everyday, every 10 minutes every day to fetch my email (via getmail), and can assure you that the 110 character change is correct. -- Added file: http://bugs.python.org/file15456/imaplib-r76683.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue5949 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue5949] IMAP4_SSL spin because of SSLSocket.suppress_ragged_eofs
Scott Dial sc...@scottdial.com added the comment: Ben, I understand that we are all volunteers here. My frustration in the lack of a de facto owner of the imaplib module and not with you personally or any other committer for that matter. As it is, there is no unittests for the imaplib module, and I am not in a position to provide a complete implementation of an IMAP server. However, I have attached a simple script demonstrating the issue. An unpatched trunk will infinite loop, consuming memory, and a patched version will throw a Traceback immediately. -- Added file: http://bugs.python.org/file15457/imaplib-eof-test.py ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue5949 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue5949] IMAP4_SSL spin because of SSLSocket.suppress_ragged_eofs
Scott Dial sc...@scottdial.com added the comment: I found myself in the mood to code, so in the spirit of every step counts, I have attached a patch that updates test_imaplib accordingly. The construction of the test framework is based loosely on test_ssl and test_socketserver. If someone felt so moved to add more test cases, then one would could simply extend SimpleIMAPHandler to handle more IMAP commands. FYI, as previously noted, on an unpatch trunk test_issue5949() is an infinite loop. -- Added file: http://bugs.python.org/file15458/test_imaplib-r76683.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue5949 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
