ANN: psutil 0.4.0 released
Hi folks,
I'm pleased to announce the 0.4.0 release of psutil:
http://code.google.com/p/psutil
=== About ===
psutil is a module providing an interface for retrieving information
on all running processes and system utilization (CPU, disk, memory,
network) in a portable way by using Python, implementing many
functionalities offered by command line tools such as ps, top, free,
lsof and others.
It works on Linux, Windows, OSX and FreeBSD, both 32-bit and 64-bit,
with Python versions from 2.4 to 3.3 by using a single code base.
=== Major enhancements ===
Aside from fixing different high priority bugs this release introduces
two new important features: disks and network IO counters.
With these, you can monitor disks usage and network traffic.
3 scripts were added to provide an example of what kind of
applications can be written with these two hooks:
http://code.google.com/p/psutil/source/browse/trunk/examples/iotop.py
http://code.google.com/p/psutil/source/browse/trunk/examples/nettop.py
http://code.google.com/p/psutil/source/browse/trunk/examples/top.py
...and here you can see some screenshots:
http://code.google.com/p/psutil/#Example_applications
=== Other enhancements ==
- Process.get_connections() has a new 'kind' parameter to filters for
connections by using different criteria.
- timeout=0 parameter can now be passed to Process.wait() to make it
return immediately (non blocking).
- Python 3.2 installer for Windows 64 bit is now provided in downloads section.
- (FreeBSD) addeed support for Process.getcwd()
- (FreeBSD) Process.get_open_files() has been rewritten in C and no
longer relies on lsof.
- various crashes on module import across differnt platforms were fixed.

Re: Need Windows user / developer to help with Pynguin
Thanks to all those who tested and replied! For Windows users who want to just run Pyguin (not modify or tinker with the source code), it would be best to bundle Pynguin up with Py2exe I considered that, but I agree that licensing issues would make it problematic. the Python installer associates .py and .pyw files with python.exe and pythonw.exe respectively, so if you add the extension as Terry mentioned, it should work. I think this is the best way to go. pynguin = pynguin.py Would it be better to go with pynguin.pyw ? Actually, I was thinking of just copying that script to something like run_pynguin.pyw Anyone able to test if just making that single change makes it so that a user can just unpack the .zip file and double click on run_pynguin.pyw to run the app? Win7, with zip built in, just treats x.zip as a directory in Explorer So, is that going to be a problem? The user just sees it as a folder, goes in and double-clicks on run_pynguin.pyw and once python is running what does it see? Are the contents of the virtually unpacked folder going to be available to the script? You pynguin.zip contains one top level file -- a directory called pynguin that contains multiple files I feel that this is the correct way to create a .zip file. I have run in to so many poorly formed .zip files (ones that extract all of their files to the current directory) that when extracting any .zip I always create a dummy folder and put the .zip in there before extracting. Mine is actually called pynguin-0.12.zip and extracts to a folder called pynguin-0.12 Extracting pynguin.zip to a pynguin directory in the same directory as pynguin.zip, the default behavior with Win7 at least, creates a new pynguin directory that contains the extracted pynguin directory. So, windows now creates the dummy folder automatically? Is the problem that the .zip has the same name (minus the extension)? Would it solve the problem to just change the name of the archive to something like pynguin012.zip ? README = README.txt Just out of curiosity, what happens if you double-click the README sans .txt? Does it make you choose which app to open with? -- http://mail.python.org/mailman/listinfo/python-list

What substantial increase? of time and space, as I said, for the temporary array that I think would be needed and which I also described in the previous paragraph that you clipped That's because I don't think it needs a temporary array. A temporary array would provide some invariant guarantees that are nice but not necessary in a lot of real-world cases. There's already a check that winds up raising an exception. Just make it empty an iterator instead. It? I have no idea what you intend that to refer to. Sorry, code path. There is already a code path that says hey I can't handle this. To modify this code path to handle the case of a generic iterable would add a tiny bit of code, but would not add any appreciable space (no temp array needed for my proposal) and would not add any runtime to people who are not passing in iterables or doing other things that currently raise exceptions. I doubt it would be very many because it is *impossible* to make it work in the way that I think people would want it to. How do you know? I have a use case that I really don't think is all that rare. I know exactly how much data I am generating, but I am generating it piecemeal using iterators. It could, but at some cost. Remember, people use ctypes for efficiency, yes, you just made my argument for me. Thank you. It is incredibly inefficient to have to create a temp array. No, I don't think I did make your argument for you. I am currently making a temp list because I have to, and am proposing that with a small change to the ctypes library, that wouldn't always need to be done. But necessary to work with blank box iterators. With your own preconceived set of assumptions. (Which I will admit, you have given quite a bit of thought to, which I appreciate.) Now you are agreeing with my argument. Nope, still not doing that. If ctype_array slice assignment were to be augmented to work with iterators, that would, in my opinion (and see below), That's better for not being absolute. Thank you for admitting other possibilities. require use of temporary arrays. Since slice assignment does not use temporary arrays now (see below), that augmentation should be conditional on the source type being a non-sequence iterator. I don't think any temporary array is required, but in any case, yes the code path through the ctypes array library __setslice__ would have to be modified where it gives up now, in order to decide to do something different if it is passed an iterable. CPython comes with immutable fixed-length arrays (tuples) that do not allow slice assignment and mutable variable-length arrays (lists) that do. The definition is 'replace the indicated slice with a new slice built from all values from an iterable'. Point 1: This works for any properly functioning iterable that produces any finite number of items. Agreed. Iterators are always exhausted. And my proposal would continue to exhaust iterators, or would raise an exception if the iterator wasn't exhausted. Replace can be thought of as delete follewed by add, but the implementation is not that naive. Sure, on a mutable length item. Point 2: If anything goes wrong and an exception is raised, the list is unchanged. This may be true on lists, and is quite often true (and is nice when it happens), but it isn't always true in general. For example, with the current tuple packing/unpacking protocol across an assignment, the only real guarantee is that everything is gathered up into a single object before the assignment is done. It is not the case that nothing will be unpacked unless everything can be unpacked. For example: a,b,c,d,e,f,g,h,i = range(100,109) (a,b,c,d), (e,f), (g,h,i) = (1,2,3,4), (5,6,7), (8,9) Traceback (most recent call last): File stdin, line 1, in module ValueError: too many values to unpack a,b,c,d,e,f,g,h,i (1, 2, 3, 4, 104, 105, 106, 107, 108) This means that there must be temporary internal storage of either old or new references. As I show with the tuple unpacking example, it is not an inviolate law that Python won't unpack a little unless it can unpack everything. An example that uses an improperly functioning generator. (snip) Yes, I agree that lists are wondrously robust. But one of the reasons for this is the flexible interpretation of slice start and end points, that can be as surprising to a beginner as anything I'm proposing. A c_uint array is a new kind of beast: a fixed-length mutable array. So it has to have a different definition of slice assignment than lists.

Note that this only applies to the ZIP extractor in Explorer; other archive programs have their own behavior. I agree with you on having a top-level directory in an archive, but MS figures users are more likely to be annoyed with files scattered around the current directory than a nested directory. Unfortunately, many archives out in the wild have a top-level directory while many others don't, so one can rarely ever be certain how a given archive is organized without opening it.

Hi,

What do you mean keys tuples?
Corrected phrase:
I would like to save many dicts with a fixed (and known) amount of keys
in a memory efficient manner (no random, but only sequential access is
required) to a file (which can later be sent over a slow expensive
network to other machines)
Example:
Every dict will have the keys 'timestamp', 'floatvalue', 'intvalue',
'message1', 'message2'
'timestamp' is an integer
'floatvalue' is a float
'intvalue' an int
'message1' is a string with a length of max 2000 characters, but can
often be very short
'message2' the same as message1
so a typical dict will look like
{ 'timetamp' : 12, 'floatvalue': 3.14159, 'intvalue': 42,
'message1' : '', 'message2' : '=' * 1999 }
What do you call many? Fifty? A thousand? A thousand million? How many
items in each dict? Ten? A million?
File size can be between 100kb and over 100Mb per file. Files will be
accumulated over months.
I just want to use the smallest possible space, as the data is collected
over a certain time (days / months) and will be transferred via UMTS /
EDGE / GSM network, where the transfer takes already for quite small
data sets several minutes.
I want to reduce the transfer time, when requesting files on demand (and
the amount of data in order to not exceed the monthly quota)
As the keys are the same for each entry I considered converting them to
tuples.
I don't even understand what that means. You're going to convert the keys
to tuples? What will that accomplish?
As the keys are the same for each entry I considered converting them
(the before mentioned dicts) to tuples.
so the dict { 'timetamp' : 12, 'floatvalue': 3.14159, 'intvalue': 42,
'message1' : '', 'message2' : '=' * 1999 }
would become
[ 12, 3.14159, 42, '', ''=' * 1999 ]
The tuples contain only strings, ints (long ints) and floats (double)
and the data types for each position within the tuple are fixed.
The fastest and simplest way is to pickle the data or to use json. Both
formats however are not that optimal.
How big are your JSON files? 10KB? 10MB? 10GB?
Have you tried using pickle's space-efficient binary format instead of
text format? Try using protocol=2 when you call pickle.Pickler.
No. This is probably already a big step forward.
As I know the data types if each element in the tuple I would however
prefer a representation, which is not storing the data types for each
typle over and over again (as they are the same for each dict / tuple)
Or have you considered simply compressing the files?
Compression makes sense but the inital file format should be already
rather 'compact'
I could store ints and floats with pack. As strings have variable length
I'm not sure how to save them efficiently (except adding a length first
and then the string.
This isn't 1980 and you're very unlikely to be using 720KB floppies.
Premature optimization is the root of all evil. Keep in mind that when
you save a file to disk, even if it contains only a single bit of data,
the actual space used will be an entire block, which on modern hard
drives is very likely to be 4KB. Trying to compress files smaller than a
single block doesn't actually save you any space.
Is there already some 'standard' way or standard library to store such
data efficiently?
Yes. Pickle and JSON plus zip or gzip.
pickle protocol-2 + gzip of the tuple derived from the dict, might be
good enough for the start.
I have to create a little more typical data in order to see how many
percent of my payload would consist of repeating the data types for each
tuple.

Customizing class attribute access in classic classes
Hi, I'm wondering if there is any way to customize class attribute access on classic classes? So this works: class Meta(type): def __getattr__(cls, name): return Customized + name class A: __metaclass__ = Meta print A.blah but it turns A into a new-style class. If Meta does not inherit from type, the customization works but A ends up not being a class at all, severely restricting its usefulness. I then hoped I could get Meta to inherit from types.ClassType but that wasn't allowed either. Is there any way to do this or is it just a limitation of classic classes?

Re: Convert DDL to ORM

I've recently come across an ORM library (SQLalchemy), and it seems like a quite useful abstraction. Is there a way to convert my DDL to ORM code? It's called reverse engineering. Some ORMs, e.g. Django's ORM can reverse engineer the database into Django Models by using `./manage.py inspectdb`.

[issue13290] get vars for object with __slots__
New submission from João Bernardo jbv...@gmail.com:
I just realized the builtin function `vars` can't handle custom objects without
the __dict__ attribute.
It would be nice if it worked with objects that have __slots__ to make them
look more like normal objects and to make debugging easier.
I changed the source of Python/bltinmodule.c to accept this new case, but, as
I'm fairly new to the C API, it may not be much good.
I'm attaching the whole file to this Issue and the `builtin_vars` function was
modified (lines 1859 to 1921) to work with:
__slots__ = ('a', 'b', 'c')
__slots__ = 'single_name'
__slots__ = {'some': 'mapping'}
The output is a dict (just like in the __dict__ case).
#Example
class C:
__slots__ = ['x', 'y']
c = C()
c.x = 123
vars(c)
{'x': 123}

[issue13281] robotparser.RobotFileParser ignores rules preceeded by a blank line
Petri Lehtinen pe...@digip.org added the comment: Because of the line break, clicking that link gives Server error 404. I don't see a line break, but the comma after the link seems to breaks it. Sorry. The way I read the grammar, 'records' (which start with an agent line) cannot have blank lines and must be separated by blank lines. Ah, true. But it seems to me that having blank lines elsewhere doesn't break the parsing. If other robots.txt parser implementations allow arbitrary blank lines, we could add a strict=False parameter to make the parser non-strict. This would be a new feature of course. Does the parser currently handle blank lines between full records (agentline(s) + ruleline(s)) correctly? I also do not see Crawl-delay and Sitemap (from whitehouse.gov) in the grammar referenced above. So I wonder if de facto practice has evolved. The spec says: Lines with Fields not explicitly specified by this specification may occur in the /robots.txt, allowing for future extension of the format. So these seem to be nonstandard extensions. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13281 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue13238] Add shell command helpers to shutil module
Antoine Pitrou pit...@free.fr added the comment: With the default whitespace escaping (which allows spaces in filenames), wildcard matching still works (thus the list of directories matching the ../py* pattern), but with full quoting it breaks (thus the nothing named '../py*' result). My question is why it would be a good idea to make a difference between whitespace and other characters. If you use a wildcard pattern, generally it won't contain spaces at all, so you don't have to quote it. If you are injecting a normal filename, noticing that whitespace gets quoted may get you a false sense of security until somebody injects a wildcard character that won't get quoted. So what I'm saying is that a middleground between quoting and no quoting is dangerous and not very useful. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13238 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue5661] asyncore should catch EPIPE while sending() and receiving()
Xavier de Gaye xdeg...@gmail.com added the comment: The test fails when use_poll is True. The difference between using poll() and poll2(): poll: All the read events are processed before the write events, so the close after the first recv by TestHandler will be followed by a send by TestClient within the same call to poll(). The test is deterministic. poll2: The order in which events are received is os dependent. So it is possible that the first recv by TestHandler is the last event in the 'r' list, so that after the close, a new call to poll2() is done and the first event in this new 'r' list, is not the expected write event for TestClient. What about forcing self.use_poll to False, before calling loop_waiting_for_flag() ? The drawback being that the test will be run twice with the same environment. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue5661 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue5661] asyncore should catch EPIPE while sending() and receiving()
Charles-François Natali neolo...@free.fr added the comment: The test fails when use_poll is True. The difference between using poll() and poll2(): poll uses select(2), while poll2 uses poll(2) (duh, that's confusing). It seems that on OS X Snow Leopard, poll(2) sets the POLLPRI flag upon EPIPE (and probably doesn't return the FD in the exception set for select(2)...). Not sure whether it's legal, but it's the only OS to do that (POLLPRI usually used for OOB data). Also, note that Tiger doesn't behave that way. OS X often offers such surprises :-) What about forcing self.use_poll to False, before calling loop_waiting_for_flag() ? The drawback being that the test will be run twice with the same environment. I just added an handle_expt() handler, and it works fine.

Patches are welcome. Martin: Please understand that there are *MANY* more issues with reloading Python in the same process, as a really large number of stuff doesn't get cleanup up on shutdown.

[issue12498] asyncore.dispatcher_with_send, disconnection problem + miss-conception
Xavier de Gaye xdeg...@gmail.com added the comment: Actually the class asyncore.dispatcher_with_send do not handle properly disconnection. When the endpoint shutdown his sending part of the socket, but keep the socket open in reading, the current implementation of dispatcher_with_send will close the socket without sending pending data. Adding this method to the class fix the problem: def handle_close(self): if not self.writable(): dispatcher.close() This does not seem to work. The attached Python 3.2 script 'asyncore_12498.py' goes into an infinite loop of calls to handle_read/handle_close when handle_close is defined as above. In this script the Writer sends a 4096 bytes message when connected, the Reader reads only 64 bytes and closes the connection afterwards. Then follows the sequence: select() returns a read event handled by handle_read() handle_read() calls recv() socket.recv() returns 0 to indicate a closed connection recv() calls handle_close This sequence is repeated forever in asyncore.loop() since out_buffer is never empty. Note that after the first 'handle_close' has been printed, there are no 'handle_write' printed, which indicates that the operating system (here linux) states that the socket is not writable. -- nosy: +xdegaye Added file: http://bugs.python.org/file23547/asyncore_12498.py ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12498 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue11638] python setup.py sdist crashes if version is unicode
David Barnett davidbarne...@gmail.com added the comment:
One way to fix the symptom (maybe not the correct way) would be to edit
tarfile._Stream._init_write_gz and change the line that reads
self.__write(self.name + NUL)
to something like
self.__write(self.name.encode('utf-8') + NUL)
tarfile is building up an encoded stream of bytes, and whatever self.name is it
needs to be encoded before being inserted into the stream. I'm not positive
UTF-8 is right, and maybe it should only convert if isinstance(self.name,
unicode).
