[RELEASED] Python 3.3.0 beta 2
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 On behalf of the Python development team, I'm happy to announce the second beta release of Python 3.3.0 -- a little later than originally scheduled, but much better for it. This is a preview release, and its use is not recommended in production settings. Python 3.3 includes a range of improvements of the 3.x series, as well as easier porting between 2.x and 3.x. Major new features and changes in the 3.3 release series are: * PEP 380, syntax for delegating to a subgenerator (yield from) * PEP 393, flexible string representation (doing away with the distinction between wide and narrow Unicode builds) * A C implementation of the decimal module, with up to 80x speedup for decimal-heavy applications * The import system (__import__) now based on importlib by default * The new lzma module with LZMA/XZ support * PEP 397, a Python launcher for Windows * PEP 405, virtual environment support in core * PEP 420, namespace package support * PEP 3151, reworking the OS and IO exception hierarchy * PEP 3155, qualified name for classes and functions * PEP 409, suppressing exception context * PEP 414, explicit Unicode literals to help with porting * PEP 418, extended platform-independent clocks in the time module * PEP 412, a new key-sharing dictionary implementation that significantly saves memory for object-oriented code * PEP 362, the function-signature object * The new faulthandler module that helps diagnosing crashes * The new unittest.mock module * The new ipaddress module * The sys.implementation attribute * A policy framework for the email package, with a provisional (see PEP 411) policy that adds much improved unicode support for email header parsing * A collections.ChainMap class for linking mappings to a single unit * Wrappers for many more POSIX functions in the os and signal modules, as well as other useful functions such as sendfile() * Hash randomization, introduced in earlier bugfix releases, is now switched on by default In total, almost 500 API items are new or improved in Python 3.3. For a more extensive list of changes in 3.3.0, see http://docs.python.org/3.3/whatsnew/3.3.html (*) To download Python 3.3.0 visit: http://www.python.org/download/releases/3.3.0/ Please consider trying Python 3.3.0 with your code and reporting any bugs you may notice to: http://bugs.python.org/ Enjoy!

[ANNOUNCE] Campaign to support the notmm project!
Hi All, I'm raising a campaign to support the notmm project, a freely accessible open source project i created to develop an advanced web framework for Django. Furthermore the project is using ConfigObj internally for allowing flexible configuration and Cython for extending Django apps in C. If you would like thus supporting the time and work I invested into the project I would really appreciate a small donation, as I'm now really poor and cannot even finance the server hosting. Your donation would therefore be used to put back the website online and continue active development of an alternative web framework for Python which doesn't necessarily force its users to log in Facebook or Twitter for commenting, or syndication purposes.. Lastly if you have any comments on this letter or would like further info before making a donation it will be my pleasure to help..

Re: Threads and sockets

Because of the way PJL works I have to do both in the same process(script). If I understand that right, you are opening a TCP connection, so obviously this must be done in the same process, regardless of what PJL (whatever that exactly is) does. At the moment I do not start to read responses until the data has been sent to the printer. However it seems I am missing some responses from the printer whilst sending the data, so I need to be able to do the 2 things at the same time. Using TCP, that shouldn't happen, so I really wonder what exactly you are doing here. Can I open a port once and then use 2 different threads, one to write to the post and one to read the responses)? Yes, definitely, take a look at the select() function of the select module. This basically looks like this: (r, w, x) = select(...) if r: # read and handle incoming data ... if w: # write pending output data ... if x: # handle connection failure ... If all this is not what you are doing and what you want (which I'm not 100% sure of) then please elaborate a bit what you're doing and what kind of connection you are using. Happy hacking!

testfixtures 2.3.5 Released!
Hi All, I'm pleased to announce the release of testfixtures 2.3.5. testfixtures is a collection of helpers for writing succinct unit tests including help for: - Comparing objects and sequences Better feedback when the results aren't as you expected along with support for comparison of objects that don't normally support comparison. - Mocking out objects and methods Easy to use ways of stubbing out objects, classes or individual methods for both doc tests and unit tests. Special helpers are provided for testing with dates and times. - Testing logging Helpers for capturing logging output in both doc tests and unit tests. - Testing stream output Helpers for capturing stream output, such as that from print statements, and making assertion about it. - Testing with files and directories Support for creating and checking files and directories in sandboxes for both doc tests and unit tests. - Testing exceptions Easy to use ways of checking that a certain exception is raised, even down the to the parameters the exception is raised with. This release fixes a small bug that meant failures in dictionary comparison didn't always produce the same output. (It was correct, just partly unsorted) The package is on PyPI and a full list of all the links to docs, issue trackers and the like can be found here: http://www.simplistix.co.uk/software/python/testfixtures Any questions, please do ask on the Testing in Python list or on the Simplistix open source mailing list... cheers, Chris -- Simplistix - Content Management, Batch Processing Python Consulting - http://www.simplistix.co.uk -- http://mail.python.org/mailman/listinfo/python-list

It's a useful construct in theory when you want to write in recursion, which was part of the rationale behind PEP 3130 (btw, Terry, it would have been nice if you'd mentioned the number instead of sending me to the index to try to figure out which one you were referring to, but anyway). But how often is it actually useful in practice? I've never actually used this_function other than in writing a crazy recursive lambda (was testing different languages' handling of infinite recursion - high level languages shouldn't segfault, one much-maligned language DOES).

ANN: psutil 0.6.0 released
Hi folks, I'm pleased to announce the 0.6.0 release of psutil: http://code.google.com/p/psutil/ This is one of the best releases so far as it addresses two important issues: system memory functions management and permission errors occurring on Windows and OSX. === Memory functions === psutil.phymem_usage() and psutil.virtmem_usage() are deprecated. Instead we now have psutil.virtual_memory() and psutil.swap_memory(), which should provide all the necessary pieces to monitor the actual system memory usage, both physical and swap/disk related. The refactoring was modeled after Zabbix, see: http://code.google.com/p/psutil/issues/detail?id=311 http://blog.zabbix.com/when-alexei-isnt-looking/#vm.memory.size http://www.zabbix.com/documentation/2.0/manual/appendix/items/vm.memory.size_params If you don't want to read how and why I did that, the bottom line is: if you want to monitor actual system memory usage in a cross platform fashion use: psutil.virtual_memory().available === No more AccessDenied exceptions when querying processes === On Windows and OSX the Process methods below were always raising AccessDenied for any process owned by another user: OSX - name - get_memory_info() - get_memory_percent() - get_cpu_times() - get_cpu_percent() - get_num_threads() WINDOWS - create_time - get_children() - get_cpu_times() - get_cpu_percent() - get_memory_info() - get_memory_percent() - get_num_handles() - get_io_counters() Especially on OSX this made psutil basically unusable as a limited user, even for determining basic process information such as CPU percent or memory usage. Now this is no longer the case. For further details see: http://code.google.com/p/psutil/issues/detail?id=297 http://code.google.com/p/psutil/issues/detail?id=303 === Other major enhancements === - per-process extended memory stats. - per-process number of voluntary and involuntary context switches. - per-process connections: added UNIX sockets support. - (BSD) Process.get_connections() rewritten in C and no longer requiring lsof. - (OSX) added support for process cwd - psutil.network_io_counters() now provides the number of in/out packets dropped and with errors. - new example scripts: example/meminfo.py example/free.py example/netstat.py example/pmap.py === New features by example === import psutil, os p = psutil.Process(os.getpid()) p.get_num_ctx_switches() amount(voluntary=78, involuntary=19) p.get_ext_memory_info() meminfo(rss=9662464, vms=49192960, shared=3612672, text=2564096, lib=0, data=5754880, dirty=0) p.get_connections(kind='unix') [connection(fd=8, family=1, type=1, local_address='/tmp/unix_socket.sock', remote_address=None, status='')] psutil.virtual_memory() vmem(total=8374149120L, available=2081050624L, percent=75.1, used=8074080256L, free=300068864L, active=3294920704, inactive=1361616896, buffers=529895424L, cached=1251086336) psutil.swap_memory() swap(total=2097147904L, used=296128512L, free=1801019392L, percent=14.1, sin=304193536, sout=677842944) === Compatitility notes === 0.6.0 version does not introduce any backward incompatibility. Nevertheless it introduces some deprecations warnings: - psutil.phymem_usage() is deprecated in favor of psutil.virtual_memory() - psutil.virmem_usage() is deprecated in favor of psutil.swap_memory() - psutil.cached_phymem() is deprecated in favor of psutil.virtual_memory().cached - psutil.phymem_buffers() is deprecated in favor of psutil.virtual_memory().buffers The deprecated functions will be removed in next 1.0.0 version. === Links === * Home page: http://code.google.com/p/psutil * Source tarball: http://psutil.googlecode.com/files/psutil-0.6.0.tar.gz * Api Reference: http://code.google.com/p/psutil/wiki/Documentation Please try out this new release and let me know if you experience any problem by filing issues on the bug tracker.

for tracing purposes I have added some print outs like
print('+++ before calling foo',file=sys.stderr)
x=foo(..)
print('--- after calling foo',
and within 'foo'
print(' entering foo ...',file=sys.stderr)
Now, when executing this, I always get

When outputting to stderr from C/C++ it's guaranteed that the different
outputs appear in the same order as they have been generated.
Is this guarantee no more valid in Python 3.2 ?

Re: print(....,file=sys.stderr) buffered?
As far as I know,
stdout is usually buffered (not necessary) in both C++ and Python
stderr is non-buffered in both C++ and Python (I can't imagine the point of
stderr if it were buffered)
Even with this, stdout usually come immediately - the situation you have
shouldn't happen.
Are you using an IDE? If so, which one?

When outputting to stderr from C/C++ it's guaranteed that the different
outputs appear in the same order as they have been generated.
You're not printing to stderr in the second print() call -- you're
printing to stdout. The two file objects have separate buffers and
may even be using two different buffering modes (e.g. line vs. block).
You can't interleave writes to stderr and stdout and assume order is
preserved unless you take specific steps (such as forcing them both to
be unbuffered or flushing them at certain points).
Is this guarantee no more valid in Python 3.2 ?
If you write to stderr all three times, it should work the way you
want it to.

Sharing code between different projects?
I am in the situation where I am working on different projects that might potentially share a lot of code. I started to work on project A, then switched completely to project B and in the transiction I copied over a lot of code with the corresponding tests, and I started to modify it. Now it's time to work again on project A, but I don't want to copy things over again. I would like to design a simple and nice way to share between projects, where the things I want to share are simple but useful things as for example: class TempDirectory: Create a temporary directory and cd to it on enter, cd back to the original position and remove it on exit def __init__(self): self.oldcwd = getcwd() self.temp_dir = mkdtemp() def __enter__(self): logger.debug(create and move to temp directory %s % self.temp_dir) return self.temp_dir def __exit__(self, type, value, traceback): # I first have to move out chdir(self.oldcwd) logger.debug(removing the temporary directory and go back to the original position %s % self.temp_dir) rmtree(self.temp_dir) The problem is that there are functions/classes from many domains, so it would not make much sense to create a real project, and the only name I could give might be utils or utilities.. In plus the moment the code is shared I must take care of versioning and how to link different pieces together (we use perforce by the way). If then someone else except me will want to use these functions then of course I'll have to be extra careful, designing really good API's and so on, so I'm wondering where I should set the trade-off between ability to share and burden to maintain..

Any idea why?
It looks like your registry has changed.
Most likely, or the Python installation has be damaged.
To fix this just use the Windows Explorer, click on a Python file
and use the 'Open with, Choose default program' menu and then
select the Idle IDE as the default program.
That is probably the worst choice to make -- since what you've
defined means double clicking on ANY .py file will NOT RUN IT -- but
rather attempt to open it with the editor (IDLE)... But since IDLE
itself is a .py file, it may fail to start at all.
If double-clicking an IDLE.py file does not start it, then the
registry has lost the association of .py to python.exe, not to IDLE. OR
-- .py IS associated to python.exe but the association (the run
command is not passing the .py file name to the python executable).
On WinXP (with ActiveState 2.5.x version) my associations are as:
E:\UserData\Wulfraed\My Documentsassoc .py
.py=py_auto_file
E:\UserData\Wulfraed\My Documentsftype py_auto_file
py_auto_file=E:\Python25\python.exe %1 %*
E:\UserData\Wulfraed\My Documents
(with similar entries for .pyw to hook into pythonw.exe)
{Just booted the Win7 laptop with Python 2.7.x: The only real difference
is that it uses Python.File where the above has py_auto_file}
Re-installing, as I suggested in the first response, is much easier,
especially for someone not familiar with the above.

Re: Sharing code between different projects?
I'd just create a module - called shared_utils.py or similar - and import that in both projects. It might be a bit messy if there's no 'unifying theme' to the module - but surely it'd be a lot less messy than your TempDirectory class, and anyone else who knows Python will understand 'import shared_utils' much more easily. I realise you might not want to say, but if you could give some idea what sort of projects these are, and what sorts of code you're trying to share, it might make things a bit clearer. I'm not really sure what your concerns about 'versioning and how to link different pieces together' are - what d you think could go wrong here?

There's actually much merit in a generic utilities module. Keep things nicely segregated (ideally such that you know what things depend on what other, but at very least keep track of where one ends and another begins - that's trivial if everything's one function or one class, but less so when you have a family of related functions), and then you can consider promoting one block of code to stand-alone module. But in the meantime, you have a single module used in two places, even if it doesn't have a very clear definition as yet. ChrisA -- http://mail.python.org/mailman/listinfo/python-list

[issue15564] cgi.FieldStorage should not call read_multi on files
patrick vrijlandt added the comment: I must admit my usage case is a hack, but the summary is: view a page on one computer, process it on another computer; like sending the page to a friend, with friend - self and send - upload. I found one other victim in python (https://groups.google.com/d/topic/web2py/ixeUUWryZh0/discussion) but only an occasional reference to other languages; most posts relate to security issues with mht files. My previous example only served to show that the mime-type is a necessary condition for the problem to occur; you are right that this input would be expected to throw an exception. So I went on and created a complete testcase/example (attached). The PatchedFieldStorage class parses the mht file correctly into parts. However, the names of the parts are in content-location headers inside the mht file and get lost. Also the code is ugly. Trying to better re-use existing code like in ExperimentalFieldStorage was not succesful so far: The MIME-prologue is parsed as one of the parts, and the outerboundary is not respected, losing a dataelement next to the file. The print() calls show that the next line may be valuable (like a header) or not so much (like a boundary), but so far the class has no provision for look-ahead I think. email.message_from_binary_file correctly parses my mht-files; so a completely different approach might be to more rely on that package for parsing MIME encoded data. -- Added file: http://bugs.python.org/file26780/test_cgi4.py ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15564 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15636] base64.decodebytes is only available in Python3.1+
New submission from Andrew Scheller: According to the documentation ( http://docs.python.org/py3k/library/base64.html#base64.decodebytes ) both the decodebytes and the deprecated decodestring methods are available in the base64 module in Python3.x However in Python3.0 (I'm testing with version 3.0.1 built from source) the base64 module only has the decodestring method, it doesn't have decodebytes. IMHO the documentation should be updated to reflect this.

Ronald Oussoren added the comment: I can reproduce this on an OSX 10.8 system, both using python 2.7 and python 3.3. The growth is significantly less using python 3.3. What's odd is that the growth does not occur when both test_iter calls use 124 as the argument (or larger values).

[issue15639] csv.Error description is incorrectly broad
New submission from Xavier Morel: In both Python 2.7 and Python 3.x, csv.Error is documented as: Raised by any of the functions when an error is detected. As far as I can tell from using the module and looking at the code, this is completely incorrect. There is actually a single instance of csv.Error being used: the instantiation of csv.Dialect (which converts TypeError raised from _csv._Dialect() into csv.Error, a comment notes that this is for compatibility with py 2.3). And the only way to hit that code paths seems to be subclassing `Dialect` and putting incorrect values in the various attributes (providing them to `csv.reader` raises a TypeError). I believe the documentation to csv.Error should be changed to: 1. Mark it as effectively deprecated 2. Indicate that the only situation in which it it may be raised is when initializing a subclass of csv.Dialect -- assignee: docs@python components: Documentation messages: 168096 nosy: docs@python, xmorel priority: normal severity: normal status: open title: csv.Error description is incorrectly broad versions: Python 2.7, Python 3.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15639 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15634] synchronized decorator for the threading module
R. David Murray added the comment: Writing such a decorator is pretty trivial to do. On the other hand, I've done it often enough that I could be convinced it is useful to add. I think it would be better to have a decorator generator that takes a lock as its argument, however, since an application might well want to use the same lock for sections that it doesn't make sense to decorate, or use an RLock instead of a lock.
