ANN: pyftpdlib 1.3.1 released
Hello, I'm pleased to announce release 1.3.1 of Python FTP Server library (pyftpdlib). http://code.google.com/p/pyftpdlib/ === About === Python FTP server library provides an high-level portable interface to easily write very fast asynchronous FTP/S servers with Python. === Changes === - #282: async IO loop now uses /dev/poll on Solaris (far more scalable than poll()) - #262: FTPS is now able to load a certificate chain file. - #277: added a make file for running tests and for other repetitive tasks (also for Windows). - #281: source tarballs are now hosted on PYPI to make pip install pyftpdlib easier. - #283: fixed a pretty annoying logging-related issue. - #261: (FTPS) SSL shutdown() was broken on Windows. === Links === * Online docs: http://code.google.com/p/pyftpdlib/wiki/Tutorial * FAQs: http://code.google.com/p/pyftpdlib/wiki/FAQ * Issue tracker: http://code.google.com/p/pyftpdlib/issues/list -- Giampaolo - http://grodola.blogspot.com -- https://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations/
SQLObject 1.5.2
Hello! I'm pleased to announce version 1.5.2, the second bugfix release of branch 1.5 of SQLObject. What's new in SQLObject === * Adapt duplicate error message strings for SQLite 3.8. Contributor for this release is Neil Muller. For a more complete list, please see the news: http://sqlobject.org/News.html What is SQLObject = SQLObject is an object-relational mapper. Your database tables are described as classes, and rows are instances of those classes. SQLObject is meant to be easy to use and quick to get started with. SQLObject supports a number of backends: MySQL, PostgreSQL, SQLite, Firebird, Sybase, MSSQL and MaxDB (also known as SAPDB).

ANN: MyNewspaper v4.0
Hi there, I'm really pleased to announce a new release of MyNewspaper, a web-based personal ATOM/RSS aggregator and feeds reader. This new version has been completely rewritten from scratch. It's under GNU Affero GPL License version 3 or later. Some technical points of interest: - written in Python 3.2+ - backend based on BottlePy web micro framework, FeedParser, SQLite, DateUtil - frontend with javascript (jQuery, jQueryUI) More information, and download link at: - [main] https://inigo.katxi.org/devel/mynewspaper - [code repository] https://bitbucket.org/inigoserna/mynewspaper4 BLURB: MyNewspaper can be considered an old project, as first version dates from 2005, and since then it has adopted and adapted different web paradigms: CGI running on a web server in v1.0, pure web app in v2.0, javascript and AJAX for v3.0. A couple of years after v3.0 release I abandoned it to join Google Reader wave, but since the announce of its shutdown I turned to MyNewspaper as I didn't like any of the alternatives. Thus I rewrote from scratch all the code. It was fast, I had a working version in a month, many weeks before Google Reader closed, but then it took about 10 months more to write the documentation… Anyway, this is now version 4.0, a very fast and nice web-based feeds reader for personal use. Of course, all comments, suggestions etc. are welcome. Best regards, Iñigo Serna -- https://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations/
ANN: Bookmarks v1.0
Hi there, Bookmarks is a simple personal web-based application to manage web bookmarks. It's written in Python 3.2+ and uses BottlePy web microframework and jQuery javascript library. Both are included with the package. It was coded as a funny practice, but it includes some nice features: advanced search, tags cloud, years cloud. I think this little application can be useful for anyone learning Python web programming. It's under GNU Affero GPL License version 3 or later. More information, and download link at: - [main] https://inigo.katxi.org/devel/bookmarks - [code repository] https://bitbucket.org/inigoserna/bookmarks Of course, all comments, suggestions etc. are welcome.

Calico Scheme in Python
We are writing to let you know of a recent spin-off from our Scheme implementation work: we now have a version implemented in Python. This is a full Scheme with proper tail-call recursion handling written in Python. We also added some interesting Python-Scheme interactions: * Scheme can use Python functions and libraries * You can define Scheme functions for use in Python * Python's list class serves the role for Scheme's vector class Some sample uses: You can just use calicoscheme.py as a script in Python, IronPython, or Jython: $ python calicoscheme.py Calico Scheme, version 3.0.0 Use (exit) to exit == (+ 1 1) 2 This environment has access to Python's built-ins through calicoscheme.ENVIRONMENT: == (sum '(1 2 3)) sum is found in the Python environment. You can also import and use Python libraries directly: == (using math numpy) (math numpy) == (math.sin 3.14) 0.0015926529164868282 == (numpy.array 10) array(100) == (exit) # or control+d You can also use calicoscheme inside Python: $ python import calicoscheme calicoscheme.ENVIRONMENT = globals()# set the environment to the locals here calicoscheme.start_rm() == (+ 1 1) 2 == (define! f (lambda (n) (+ n 1))) ### define! puts it in the external env == (exit) goodbye And back in Python you can call the define! function using Scheme's infrastructure: f(100) 101 You can also call into Scheme like so: calicoscheme.execute_string_rm((define x 23)) void calicoscheme.execute_string_rm(x) 23 To download and get more information, please see: http://calicoproject.org/Calico_Scheme -- https://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations/

When it's too confusing, simplify. The code you present is fine, but is more complex than it needs to be for the specific problem. Also, it's not complete: it appears to be part of some larger program that we don't have. And, it appears to have suffered re-formatting when you put it in your message, so it won't run. (Post only in plain text, not HTML; and copy-paste the code in plain text.) So: start simple, make something you understand, then gradually build it up until the point where it exhibits the behaviour you're confused by. Then, show that simple-as-possible-but-no-simpler version here, complete with the input you're using and the resulting output. URL:http://www.sscce.org/ You may find that this process gives you enough understanding that you are then able to solve the problem. Great! But, even if not, we'll need you to go through that process so we can understand.

I'll assume these are all methods of a single class SaleNote, and that none are nested. If that's the case, your problem is most likely that the second definition of save hides the first.

Somewhat related. Only yesterday I ported/reimplemented a software package to python3. On the finish line, I ran into a problem: xlwt only supports 2.6, 2.7 and 3.3. My system has python3.2. So I backtracked to python2.7. So not only do we have a schism between python2 and python3 but there's one between 3.0 and 3.3. I can't help but wonder if PEP 414 was a mistake.

The two should happily coexist. Also, the EOL for Python 3.2 is way *way* nearer than EOL of the 2.x line.

That'll have to wait till it's time for an OS overhaul. I don't do those every year. What OS? Since getting 3.3 isn't just a matter of grab the .msi/.dmg file from python.org, I'm guessing it's neither Windows nor OS X, so I'd guess you're most likely talking about Linux. On Linux, it's pretty easy to build Python from source. Debian Wheezy ships Python 3.2, so with that distro you should be able to do this: # apt-get build-dep python3 and it'll install everything you need to build Python 3.2 (and 3.3 needs the same packages). Then you just grab the source code and do the classic configure and make. Or if you don't want to build from source, you could get a package of 3.3 from somewhere. In the case of Debian, that would mean grabbing the Python package from Jessie: https://packages.debian.org/jessie/python3.3 I haven't tested, but that package will most likely install happily on a Debian Wheezy. Chances are you can find an equivalent for other Linuxes (I don't have much experience with rpm-based distros, but I'm sure there's some equivalent of apt-get build-dep). For non-Linux systems, I don't know how hard it is to get a newer Python, but it seems highly unlikely that you're forced to wait for an OS upgrade. Remember, there's nothing wrong with having lots of versions of Python installed. The package manager might provide a couple (maybe 3.1 and 3.2), but having 3.3 installed won't break scripts that depend on 3.2 being there, unless you actually switch over what 'python3' does - and even that's unlikely to break much, since most Linux distros are going to be depending more on the 2.x version than the 3.x... and those that depend on 3.x are sufficiently forward-looking to be shipping 3.3 or even 3.4, so the point is moot.

Python hackathon ideas
Hello! I'm planning a Python hackathon in my area, which will be held in a couple of weeks. Being my first organized hackathon, I don't quite know on what we will be working. One idea I have is to find a couple of open source projects and start contributing to them. Another idea is to work on Python issues from the bug tracker, but finding easy ones to contribute is not an easy task even for an intermediate developer like me. So, what I am looking for is open source Python projects with: - no tests or very few tests at all - no documentation or very scarce documentation - Python 2 only (and we'll try to port them to Python 3) I know about Python 3 Wall of superpowers, but most of the Python 2 only projects seems too big for us to tackle in one day. If you know these kind of projects or you have one which needs those kind of things, please tell me. Any idea will be appreciated. Thanks! -- https://mail.python.org/mailman/listinfo/python-list

If we assume that the author is trying to clear memory between the

Your variable 'size' is declared as size_t, which is an integer
the size of a pointer. Not necessarily the same as an int. But if
your size is reasonable, no harm done. The correct fix is to use
some other format rather than % d, I forget what one. Second

It's incorrect to cast each pointer to an int, but not the
difference of two pointers. Subtract the first, then cast if
you must. But the difference of two pointers is type ptr_diff,
and that should already be the type mem set is expecting.

[issue17088] ElementTree incorrectly refuses to write attributes without namespaces when default_namespace is used
Stefan Behnel added the comment:
@gene_wood: that's unrelated. This ticket is about attributes being rejected
incorrectly.
Fixing the example of the OP:
from xml.etree.ElementTree import *
svg = ElementTree(XML(
... svg width=12cm height=4cm viewBox=0 0 1200 400
xmlns=http://www.w3.org/2000/svg; version=1.1
... rect x=1 y=1 width=1198 height=398 fill=none stroke=blue
stroke-width=2 /
... /svg
... ))
tostring(svg.getroot()) # formatting is mine
b'svg:svg xmlns:svg=http://www.w3.org/2000/svg; height=4cm version=1.1
viewBox=0 0 1200 400 width=12cm\n
svg:rect fill=none height=398 stroke=blue stroke-width=2
width=1198 x=1 y=1 /\n
/svg:svg'
svg.write('simple_new.svg',encoding='UTF-8',default_namespace='http://www.w3.org/2000/svg')
Traceback (most recent call last):
File stdin, line 1, in module
File /usr/lib/python3.3/xml/etree/ElementTree.py, line 826, in write
qnames, namespaces = _namespaces(self._root, default_namespace)
File /usr/lib/python3.3/xml/etree/ElementTree.py, line 942, in _namespaces
add_qname(key)
File /usr/lib/python3.3/xml/etree/ElementTree.py, line 920, in add_qname
cannot use non-qualified names with
ValueError: cannot use non-qualified names with default_namespace option
svg.write('simple_new.svg',encoding='UTF-8')
So, it works without namespace defaulting and fails with an incorrect error
when a default namespace is provided. Clearly a bug.
Regarding the proposed patch: it looks like the right thing to do in general,
but it has a relatively high code impact. I would prefer a patch with lower
churn. One thing that could be tried is to use only one tag cache dict and
extend the key from the plain tag to (tag, is_attribute). Might have a
performance impact on the already slow serialiser, though. In any case, both
approaches are quite wasteful, because they duplicate the entire
namespace-prefix mapping just because there might be a single namespace that
behaves differently for atributes. An alternative could be to split the *value*
of the mapping in two: (element_prefix, attribute_prefix). This would keep the
overhead at serialisation low, with only slightly more work when building the
mapping. At first sight, I like that idea better.
This code returns a list in one case and a set-like view in another (Py3):
+if default_namespace:
+prefixes_list = [ (default_namespace, ) ]
+prefixes_list.extend(namespaces.items())
+else:
+prefixes_list = namespaces.items()
I can't see the need for this change. Why can't the default namespace be stored
in the namespaces dict right from the start, as it was before?
As a minor nitpick, this lambda based sort key:
key=lambda x: x[1]): # sort on prefix
is better expressed using operator.itemgetter(1).
I'd also rename the defaultable flag to is_attribute and pass it as keyword
argument (bare boolean parameters are unreadable in function calls).
Given the impact of this change, I'd also suggest not applying it to Py2.x
anymore.

[issue21213] Memory bomb by incorrect custom serializer to json.dumps
New submission from saaj: I was chaning an implementation of the function that is passed to json.dumps to extend serializable types. By a mistake (**return** instead of **raise**) it turned into, which at its minum can be expressed as:: def d(obj): return TypeError(repr(obj)) json.dumps(1j, default = d) After a few moments by laptop froze, though after a minute I could open shell in separate session, and top command showed that python interpretter is consuming about 4GiB of memory and 50% of 4 logical cores. Worst about it it doesn't end with any exception, it just keeps running. Without ``repr`` it ends up with somewhat expected ``RuntimeError: maximum recursion depth exceeded while getting the str of an object``. The same behaviour is on python3, where it just consumes memory with less speed.

[issue18321] Multivolume support in tarfile module
Lars Gustäbel added the comment: Okay, let me tell you why I reject your contribution at this point. The patch you submitted may be well-suited for your purposes but it does not meet the requirements of a standard library implementation because it is not generic and comprehensive enough. It contains duplicate code, spelling mistakes and needless code changes e.g. in test_tarfile.py. It does not expose one set of volumes as one tar archive to the user. It is not possible to iterate over all members of all volumes in one go. It does not allow random-access. Actually, it does not implement complete multivolume support but only the easy parts. For example, it fails to read GNU tar archives that are split in the middle of a pax header block sequence. The other way around, when writing it makes a split only when it is inside the data part of a member. Hence, it is possible that a volume turns out smaller than max_volume_size which is not only inaccurate but also bad on a tape device. If you decide that you still want multivolume support in tarfile, feel free to reopen this issue with a new and significantly better patch. I gave you a number of clues on what I think is required. -- assignee: - lars.gustaebel resolution: - rejected status: open - closed ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18321 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue19980] Improve help('non-topic') response
Jessica McKellar added the comment:
Elias, thanks for your patch!
I think it's important to add the second part of Terry's suggestion which gives
the user a specific next step to take, namely:
Try help('help') for information on recognized strings or help(str) for help
on the str class.
Can you add that to your patch?
Additionally, we'll want to make sure we don't accidentally break this new
functionality. Can you add a few test cases, for example what happens when you
run help on a module (e.g. help(os), 2) help on an instance of a class (e.g.
help(1)), and help on a string that doesn't have a special meaning, (e.g.
help(abcxyz))?
I don't see any existing tests for help(), but it is an instance of
site._Helper (as reported by type(help)), and site tests live in
Lib/test/test_site.py. It also gets loaded into builtins, so tests could also
live in Lib/test/test_builtins.py.

Senthil Kumaran added the comment: I verified the patch and this indeed corrects a nasty bug in sending a wrong header when doing it a lower level HTTPSConnection to proxy and set_tunnel (bad term) to the end host..I was worried as why we did not observe this earlier and it seems to me that the advertised way to do HTTPS CONNECT is via Proxy Handler or urllib.request and when doing it via a ProxyHandler, these wierdly named action (set_tunnel) happen underneath, but the skip_hosts bit is set as we got headers from the higher level method. and the host header is carried transparently to the tunnel connection request and thus we escaped this. The patch fixes the problem and cleans up a bit. Thanks for that , Nikolaus. This code (http/client.py) will require more attention beyond this bug too. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7776 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue4963] mimetypes.guess_extension result changes after mimetypes.init()
Toshio Kuratomi added the comment: Took a look at this and was able to reproduce it on Fedora Linux 20 and current cpython head. It is somewhat random though. I'm able to get reasonably consistent failures using image/jpeg and iterating the test case about 20 times. Additionally, it looks like the data structure that mimetypes.guess_extensions() is reading its extensions from is a list so it doesn't have to do with dictionary sort order. It has something to do with the way the extensions are read in from the files and then given to add_type(). Talking to r.david.murray I think that this particular problem can be solved by simply sorting the list of extensions prior to guess_extension taking the first extension off of the list. The question of what to do when the first extension in the list isn't the best extension should be resolved in Issue1043134. I'll attach a patch with test case for this problem. -- nosy: +a.badger Added file: http://bugs.python.org/file34821/issue4963.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4963 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
