GOZERBOT 0.9.2 RELEASED
Hello new world ! i’m glad to announce the release of version GOZERBOT 0.9.2, a bot that has been declared dead but has arrived from the pits of hell to serve our people here well ;] Discovered that SQLAlchemy has been fixed in such a way that it was easy to resurrect the thing, and release a new version of it. It’s not my intention to still maintain GOZERBOT as i prefer users to switch to JSONBOT but this switch is to be done in such a way that GOZERBOT users can port their data to JSONBOT in a proper way. Having GOZERBOT still up and running makes it easier for me to write the converting software as a GOZERBOT plugin, in which case i have better access to the data then when i have to access it from the outside. Ofcourse the conversion plugin is still to be written, but i hope that current GOZERBOT users can wait a little while before that is in place ;] You can get the new version from http://gozerbot.googlecode.com. For those who want to have a look at the future check http://jsonbot.org Well thats new from a happy camper that suddenly finds his path ahead.

Python User Group International Survey
The PSF is happy to launch today an international survey of Pythonuser group organizers to help it better serve the large and ever-expanding international Python user community. The survey contains questions on user group organization, events, demographics, and growth. There are some questions with numerical answers, and while your best guess is fine, you may find it helpful to gather some statistics on your user group membership before starting the survey (example statistics include the number of active members and the size and topics for recent user group events). We expect this survey to take around 30 minutes to complete. We appreciate your time and honesty in answering these questions. The PSF blog post announcing the survey: http://pyfound.blogspot.com/2011/06/tell-us-about-your-user-group.html The survey was written by Jessica McKellar (http://jesstess.com), organizer for the Boston Python Meetup (http://meetup.bostonpython.com), and Jesse Noller (http://jessenoller.com/), PSF board member and PyCon chair with input and feedback from survey specialists and others. https://www.surveymonkey.com/s/BWLG8SZ The survey was pretested with a handful of user group organizers, and their answers were phenomenal. Organizers have tons to say about these topics, and we hope to get a lot of great, actionable data for strengthening the relationship between the PSF and Python user groups out of this effort. Outreach, education, diversity and community building are critical for Python as a community, and the Foundation - this data should greatly assist in our targeting our resources and furthering the mission of the Foundation in all ways.

Re: windows 7 create directory with read write execute permission for everybody
* Gelonida (Sun, 26 Jun 2011 23:53:15 +0200) On this machine I used os.mkdir() / os.makedirs() and I had permission problems , but only on Windows7. Windows file permissions haven't changed since 1995. The only addition was dynamic inheritance support back in 2000. I expect, that the win32 libraries might have function calls allowing to control the permissions of a directory, but I am really bad with win32 as I worked mostly with Linux or code, that was platform independent, which Windows file permission handling is not :-( . Even Linux file systems have ACL support. It's only that few people use it since application support is sparse. And it lacks (dynamic) inheritance which is so 1980s.

Most likely, you are running python 3.x, while reading python 2.x book.
In python 3.x print is now ordinary function,
print('hello world')

Looks like the book you're reading is outdated and refers to Python 2.
In Python 3, print is a function:

Great, Chris, this is (almost) exactly what I needed.
To make it work for numbers like 1200, that have four digits but only
two of them being significant, I changed your snippet to the
following:
class Empirical(Decimal) :
@property
def significance(self) :
t = self.as_tuple()
if t[2] 0 :
return len(t[1])
else :
return len(''.join(map(str,t[1])).rstrip('0'))
Empirical('1200.').significance
2
Empirical('1200.0').significance
5
now it's only about overriding the numerical operators :)

Yep, you're pretty close!
There's a few improvements you could do, but the first one I would
recommend is to change your extremely confusing variable name:
def fileProcess(filename = 'input_text.txt'):
for line in open(filename, 'r'):
... continue as before ...
As well as making your code easier to comprehend, this means that the
file will correctly be opened at the start of the function and closed
at the end. (Default arguments are evaluated when the def statement is
executed, not when the function's called.)
The other change you need to make is to move the display into a loop
of its own. Currently you're printing out one word and one length from
each line, which isn't terribly useful. Try this:
for wordlen, wordfreq in freq.enumerate():
print(wordlen+\t+wordfreq);
This should be outside the 'for line in' loop.
There's a few other improvements possible (look up
'collections.Counter' for instance), but this should get you on the
right track!

That's for parameter errors, though; it shouldn't happen for environment errors. That's a strong distinction. If something can raise an exception because the environment external to the process has a problem, the exception should be an EnvironmentError or a subclass thereof. This maintains a separation between bugs (which usually should cause termination or fairly drastic recovery action) and normal external events (which have to be routinely handled.) It's quite possible to get a OSError on os.kill() for a number of legitimate reasons. The target process may have exited since the PID was obtained, for example.

To make it work for numbers like 1200, that have four digits but only
two of them being significant, I changed your snippet to the
following:

1) resizing of the field widths does work in principle, but the
resulting field is exactly one charakter to small.
2) I think, resizing should be clearer, but i have no idea, how.
3) The horizontal scrollbar does not work as expected. It does not react
on resizing the application window but only on resizing the headers of
the fields.
Maybe someone can give me some hints.

That last one is not true; 0 is a one-significant figure estimate, and
represents a value between -0.5 and 0.5. (It's true that zeroes to the
left are never significant, but not when there's nothing in the figure
but zeroes.)
A zero-significant figure would be an order of magnitude estimate only.
These aren't usually done in the e scientific notation, but it would
be something like 10^3 (if we assume ^ is exponentiation, not the Python
operator).
c^2 is 9 x 10^16 m^2/s^2 to one significant figure. It's 10^17 m^2/s^2
to zero (order of magnitude estimate).

[issue12326] Linux 3: tests should avoid using sys.platform == 'linux2'
Martin v. Löwis mar...@v.loewis.de added the comment: That would be incorrect for some systems. For example, FreeBSD does change sets of symbolic constants across system releases (mostly additions, but sometimes also removals). Back then, SunOS 4 and SunOS 5 were completely unrelated systems. Well, I don't see the problem in that case. What I'm advocating is to special-case Linux (and any other system where major version numbers don't mean much). The point I (and others) have been trying to make is that 99% of the time, people using sys.platform really mean platform.system() or uname[0], since they're only interested in the operating system, and don't care about the release. That's true of the vast majority of such occurrences in Lib/test, and probably true of the vast majority of the user code base. I don't argue with that. I agree the code is broken (although I disagree that platform.system is the right answer in most cases), but that doesn't help resolving this issue (unless the resolution is no change, which I still oppose to). Furthermore, at least on Linux, the major version number doesn't mean anything Indeed - hence I propose to drop it from sys.platform if the system is Linux. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12326 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue6721] Locks in python standard library should be sanitized on fork
Antoine Pitrou pit...@free.fr added the comment: If there's agreement that the general problem is unsolvable (so fork and threads just don't get along with each other), what we could attempt is trying to limit the side effects in the standard library, so that fewest users as possible are affected by this problem. Actually, I think Charles-François' suggested approach is a good one. For instance, having deadlocks just because of print statements sounds like a bad QoI that we could attempt to improve. Is there a reason while BufferedIO needs to hold its internal data-structure lock (used to make it thread-safe) while it's doing I/O and releasing the GIL? I would think that it's feasible to patch it so that its internal lock is only used to synchronize accesses to the internal data structures, but it is never held while I/O is performed (and thus the GIL is released -- at which point, if another threads forks, the problem appears). Not really. Whether you update the internal structures depends on the result of the I/O (so that e.g. two threads don't flush the same buffer simultaneously). Also, finer-grained locking is always a risky endeavour and we already have a couple of bugs to fix in the current buffered I/O implementation :-/ -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue6721 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Löwis rep...@bugs.python.org a écrit : What I'm advocating is to special-case Linux (and any other system where major version numbers don't mean much). Actually, it would itself break compatibility, because sys.platform would jump from linux2 to linux from one Python release to another. It would therefore only be applicable, at best, to 3.3. I think we should at least document the idiom of using sys.platform.startswith(...), and mention the platform module as an alternative.

[issue10181] Problems with Py_buffer management in memoryobject.c (and elsewhere?)
Stefan Krah stefan-use...@bytereef.org added the comment: Nick, you know a lot about this issue and I'm probably missing many things here. I misunderstood your concept of PyManagedBuffer, so my previous posting might have been hard to understand. I'd appreciate if you (or anyone in this thread) could comment if the following would work *in theory*, even if you are against an additional getslicedbufferproc: As I understand, there are two major issues that complicate the code: 1) the copying in PyMemoryView_FromBuffer() 2) slicing To address 1), I wanted to create new memoryview objects exclusively from proper base objects that implement the buffer protocol. So the plan was to create small wrapper object inside PyMemoryView_FromBuffer() that handles enough of the buffer protocol to be usable inside the stdlib for one-dimensional objects. The actual memoryview would then be created by calling PyMemoryView_FromObject() on that wrapper. [PyMemoryView_FromObject() would then obviously not call PyMemoryView_FromBuffer(), but would create the view directly.] To address 2), buffers would *always* have to be filled in by the original exporting object, hence the proposal to add a getslicedbufferproc. Then memoryview would always have a proper base object and could always call getbuffer()/INCREF(base) and releasebuffer()/DECREF(base). I thought this would make the code much cleaner. Direct: the view is directly accessing an underlying object via the PEP 3118 API Indirect: the view has a reference to another memoryview object that it is using as a data source Is there still a difference if only the original base object manages buffers and they are never copied? This is better than requiring that every implementor of the buffer API worry about the slicing logic - we can do it right in memoryview and then implementers of producer objects don't have to worry about it. I'm not sure, but my reasoning was that e.g. in numpy the slicing logic is already in place. Then again, I don't know if it is a legitimate use of buf, shapes and strides to implement slicing. According to this mail, slicing information was supposed to be part of the memoryview struct: http://mail.python.org/pipermail/python-dev/2007-April/072584.html -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10181 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue10181] Problems with Py_buffer management in memoryobject.c (and elsewhere?)
Pauli Virtanen p...@iki.fi added the comment: skrah writes: I think slicing (esp. multidimensional slicing) would be greatly simplified if we added a requirement for the *exporting* object to provide a sliced view. (The same applies to sub-views, also see source comments below [1]). For example, an exporting object could provide a sliced view by adding a getslicedbufferproc to PyBufferProcs: int PyObject_GetSlicedBuffer(PyObject *obj, Py_buffer *view, int flags, PyObject *key); The same thing can be done via PyObject_GetBuffer(obj, view, flags); PyBuffer_Slice(view, sliced_view, flags, key); given an implementation of PyBuffer_Slice. The logic in PyBuffer_Slice does not depend on where the buffer comes from, and every buffer can be sliced. As far as I see, the advantage of `getslicedbufferproc` would be to make the implementation of PyMemoryView simpler, but not much else. In my view, having each exporter implement the same logic by itself would only be an unnecessary burden. o The invariant that all allocated memory in the buffer belongs to the exporting object remains intact. Numpy arrays do not have this invariant, and they happily re-export memory owned by someone else. This is one root of problems here: the PEP implicitly assumes that re-exporting buffers (e.g. memoryview's implementation of `getbuffer`) is done in the way Numpy does it. Because of this, there is no mechanism for incrementing the refcount of an existing buffer export. Maintaining the above invariant then unavoidably leads to strange behavior in corner cases (which probably are very rare, as mentioned above), and as happened here, make the implementation messy and lead to bugs. The invariant *is* required for guaranteeing that `memoryview.release()` always succeeds. Such a method probably wasn't foreseen in the PEP (and I did not remember that it existed in my first patch), as Numpy arrays don't have any equivalent. The alternatives here are (i) do as Numpy does and give up the invariant and allow `.release()` to fail in some cases, or (ii) document the corner cases in the interface spec and try to detect them and fail if they occur. Which of these is chosen probably does not matter much in practice, but having PyManagedBuffer will make implementing either choice easier. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10181 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue12418] python should inherit the library search path from the compiler for stdlib extensions
New submission from Steve Langasek steve.langa...@ubuntu.com:
related to http://bugs.python.org/issue11715
python 2.7 and 3.1 now include a patch for behavior specific to Ubuntu and
Debian to search in multiarch directories for libraries needed for building
stdlib extensions.
This distro-specific patch is unnecessary if instead python could just query
and use the default search path from the compiler.
With gcc, it's possible to query the list of built-in library directories with:
$ gcc -print-search-dirs | sed -n -e's/libraries: =//p' | sed -e's/:/\n/g' |
xargs -n1 readlink -f
and the include directories with:
$ gcc -v -E - /dev/null 21 | awk '/^#include/,/^End of search/ {i=1} i==1
/^ / {print}'
(additional filtering, to exclude compiler-internal directories, may be
sensible.)
Having python query and use these directories when searching for libraries
would make the build system more robust in a variety of circumstances.

[issue10181] Problems with Py_buffer management in memoryobject.c (and elsewhere?)
Nick Coghlan ncogh...@gmail.com added the comment:
I'll try to do a summary of the conversation so far, since it's quite long and
hard to follow.
The basic issue is that memoryview needs to support copying and slicing that
creates a new memoryview object. The major problem with that is that the PEP
3118 semantics as implemented operate in such a way that neither copying the
Py_buffer struct *nor* requesting a new copy of the struct from the underlying
object will do the right thing in all cases. (According to the PEP *as written*
copying probably should have been OK, but the implementation doesn't match the
PEP in several important respects such that copying is definitely wrong in the
absence of tight control of the lifecycles of copies relative to the original).
Therefore, we either need to redesign the buffer export from memoryview to use
daisy chaining (such that in m = memoryview(obj); m2 = m[:]; m3 = m2[:] m3
references m2 which references m which in turn references obj) or else we need
to introduce an internal reference counted object (PyManagedBuffer) which
allows a single view of an underlying object to be safely shared amongst
multiple clients (such that m, m2 and m3 would all reference the same managed
buffer instance which holds the reference to obj). My preference is strongly
for the latter approach as it prevents unbounded and wasteful daisy chaining
while also providing a clean, easy to use interface that will make it easier
for 3rd parties to write PEP 3118 API consumers (by using PyManagedBuffer
instead of the raw Py_buffer struct).
Once that basic lifecycle problem for the underlying buffers is dealt with then
we can start worrying about other problems like exporting Py_buffer objects
from memoryview instances correctly. The lifecycle problem is unrelated to the
details of the buffer *contents* though - it's entirely about the fact that
clients can't safely copy all those pointers (as some may refer to addresses
inside the struct) and asking the original object for a fresh copy is permitted
to return a different answer each time.
The actual *slicing* code in memoryview isn't too bad - it just needs to use
dedicated storage rather than messing with the contents of the Py_buffer struct
it received from the underlying object. Probably the easiest way to handle that
is by having the PyManagedBuffer reference be in *addition* to the current
Py_buffer struct in the internal state - then the latter can be used to record
the effects of the slicing, if any. Because we know the original Py_buffer
struct is guaranteed to remain alive and unmodified, we don't need to worry
about fiddling with any copied pointers - we can just leave them pointing into
the original structure.
When accessed via the PEP 3118 API, memoryview objects would then export that
modified Py_buffer struct rather than the original one (so daisychaining would
be possible, but we wouldn't make it easy to do from pure Python code, as both
the memoryview constructor and slicing would give each new memoryview object a
reference to the original managed buffer and just update the internal view
details as appropriate.
Here's the current MemoryView definition:
typedef struct {
PyObject_HEAD
Py_buffer view;
} PyMemoryViewObject;
The TL;DR version of the above is that I would like to see it become:
typedef struct {
PyObject_HEAD
PyManagedBuffer source_data; // shared read-only Py_buffer access
Py_buffer view; // shape, strides, etc potentially modified
} PyMemoryViewObject;
Once the internal Py_buffer had been initialised, the memoryview code actually
wouldn't *use* the source data reference all that much (aside from eventually
releasing the buffer, it wouldn't use it at all). Instead, that reference would
be retained solely to control the lifecycle of the original Py_buffer object
relative to the modified copies in the various memoryview instances.
Does all that make my perspective any clearer?

[issue12421] Use PYTHON when calling Parser/asdl_c.py
R. David Murray rdmur...@bitdance.com added the comment: I don't believe we have any desire to support unix systems that do not define 'python', and 'python3' executables in the path. If the distribution wishes to do that they'll have to patch everything to accommodate it. That however is mostly irrelevant to this case. asdl_c.py is not needed for building python. The files it generates are already generated and included in the release tarballs, and in the release tarballs the file timestamps should be such that asdl_c.py is not invoked. (When working from a checkout this may not be true due to vcs tool file timestamp issues; you just have to touch the files manually in that case.) When the file *is* run, it is not the python being built that is used to run it, it is an already existing python.

[issue12398] Sending binary data with a POST request in httplib can cause Unicode exceptions
R. David Murray rdmur...@bitdance.com added the comment: And finally, your program does *not* succeed on Python3, except in the trivial sense that on python3 you never attempt to add the string and bytes data. It is exactly this kind of programming error that Python3 is designed to avoid: instead of sometimes getting a UnicodeDecodeError depending on what is in the bytes string, you *always* get a Can't convert 'bytes' object to str implicitly error when you attempt to add string and bytes. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12398 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue12398] Sending binary data with a POST request in httplib can cause Unicode exceptions
sorin sorin.sbar...@gmail.com added the comment: Right, so you have some binary data and you want to sent it to `httplib`. This worked in the past when `msg` was a non-unicode string, but starting with Python 2.7 this became an unicode string, so when you try to append the `message` if will fail because it will try to decode it. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12398 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue12420] distutils crashes if PATH is not defined
Éric Araujo mer...@netwok.org added the comment: Thanks for the report. Can you tell how you ran into this? Did you call the function directly, or did you get the bug while running a setup.py command? Also, what do you mean by crash? We use that for CPython segmentation faults, not regular misbehavior. If you could attach the exact command or script that triggered the bug and the full traceback, it would help. I don’t think using the current directory is a good idea: it’s a security hazard. -- assignee: tarek - eric.araujo type: - behavior versions: -Python 2.6, Python 3.1, Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12420 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue12416] packaging does not have hooks callable during distribution removal
Éric Araujo mer...@netwok.org added the comment: I have no objection, but you may want to ask on the fellowship ML first. Should the hooks be run before the removal or just after? (Debian for example has both, which makes four hooks: preinst, postinst, prerm, postrm). Our setup_hooks (used with pysetup commands) are run right after the setup.cfg file is parsed, before any operation is started. Regarding implementation: The hook should be defined in the global section of setup.cfg; upon installation, packaging would write this info into the dist-info directory (say in an UNINSTALLHOOKS file), which would be read when preparing an uninstallation. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12416 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue12420] distutils crashes if PATH is not defined
Henry Precheur he...@precheur.org added the comment:
Sorry crash wasn't the right term. It's just that distutils tests fail.
I ran into that when trying to run unit tests without any environment
variable (see #12401).
$ env -i ./python ./Lib/test/regrtest.py test_distutils
[1/1] test_distutils
test test_distutils crashed -- Traceback (most recent call last):

Maybe it's not really a problem, and having a system without PATH
defined shouldn't be supported because it's too weird.
