pylib-1.4.1: bug fixes
py-1.4.1: cross-python lib for fs path, code, io, ... manipulations === This is a bug fix release of the py lib, see below for detailed changes. The py lib is a small library comprising APIs for filesystem and svn path manipulations, dynamic code construction and introspection, a Py2/Py3 compatibility namespace (py.builtin), IO capturing, terminal colored printing (on windows and linux), ini-file parsing and a lazy import mechanism. It runs unmodified on all Python interpreters compatible to Python2.4 up until Python 3.2, PyPy and Jython. The general goal with py is to provide stable APIs for some common tasks that are continously tested against many Python interpreters and thus also to help transition. Here are some docs: http://pylib.org NOTE: The prior py-1.3.X versions contained py.test which since py-1.4.0 comes as its own separate pytest distribution, see: http://pytest.org Also, the py.cleanup|py.lookup|py.countloc helpers are now part of the pycmd distribution, see http://pypi.python.org/pypi/pycmd Changes between 1.4.0 and 1.4.1 == - fix issue1 - py.error.* classes to be pickleable - fix issue2 - on windows32 use PATHEXT as the list of potential extensions to find find binaries with py.path.local.sysfind(commandname) - fix (pytest-) issue10 and refine assertion reinterpretation to avoid breaking if the __nonzero__ of an object fails - fix (pytest-) issue17 where python3 does not like star-imports, leading to misrepresentation of import-errors in test modules - fix ``py.error.*`` attribute pypy access - allow path.samefile(arg) to succeed when arg is a relative filename - fix (pytest-) issue20 path.samefile(relpath) works as expected now -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations/
pytest-2.0.1: bug fixes and better asserts
py.test 2.0.1: bug fixes and better asserts === Welcome to pytest-2.0.1, a maintenance and bug fix release of pytest, a mature testing tool for Python, supporting CPython 2.4-3.2, Jython and latest PyPy interpreters. See extensive docs with tested examples here: http://pytest.org/ If you want to install or upgrade pytest, just type one of:: pip install -U pytest # or easy_install -U pytest Many thanks to all issue reporters and people asking questions or complaining. Particular thanks to Floris Bruynooghe and Ronny Pfannschmidt for their great coding contributions and many others for feedback and help. best, holger krekel Changes between 2.0.0 and 2.0.1 -- - refine and unify initial capturing so that it works nicely even if the logging module is used on an early-loaded conftest.py file or plugin. - fix issue12 - show plugin versions with --version and --traceconfig and also document how to add extra information to reporting test header - fix issue17 (import-* reporting issue on python3) by requiring py1.4.0 (1.4.1 is going to include it) - fix issue10 (numpy arrays truth checking) by refining assertion interpretation in py lib - fix issue15: make nose compatibility tests compatible with python3 (now that nose-1.0 supports python3) - remove somewhat surprising same-conftest detection because it ignores conftest.py when they appear in several subdirs. - improve assertions (not in), thanks Floris Bruynooghe - improve behaviour/warnings when running on top of python -OO (assertions and docstrings are turned off, leading to potential false positives) - introduce a pytest_cmdline_processargs(args) hook to allow dynamic computation of command line arguments. This fixes a regression because py.test prior to 2.0 allowed to set command line options from conftest.py files which so far pytest-2.0 only allowed from ini-files now. - fix issue7: assert failures in doctest modules. unexpected failures in doctests will not generally show nicer, i.e. within the doctest failing context. - fix issue9: setup/teardown functions for an xfail-marked test will report as xfail if they fail but report as normally passing (not xpassing) if they succeed. This only is true for direct setup/teardown invocations because teardown_class/ teardown_module cannot closely relate to a single test. - fix issue14: no logging errors at process exit - refinements to collecting output on non-ttys - refine internal plugin registration and --traceconfig output - introduce a mechanism to prevent/unregister plugins from the command line, see http://pytest.org/plugins.html#cmdunregister - activate resultlog plugin by default - fix regression wrt yielded tests which due to the collection-before-running semantics were not setup as with pytest 1.3.4. Note, however, that the recommended and much cleaner way to do test parametraization remains the pytest_generate_tests mechanism, see the docs. -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations/

Turbogears 2.1 with mako tmplates
Hi!, I am a python programmer. For web-based solutions, I have started learning TG 2.1 By and large, the documentation on TG 2.1 official site is a work-in-process. As regards to the templates, it tells how to go about Genshi. I wish to go with mako. Gone through the docs of mako (they are good). But still, it would be better if I can get a tutorial explaining using TG 2.1 with mako. (It will save me from re-inventing the wheel, if somebody has written docs on these lines).

Hi there!
I'm having trouble to wrap my brain around this kind of problem:
What I have :
1) list of dicts
2) list of keys that i would like to be my grouping arguments of
elements from 1)
3) list of keys that i would like do aggregation on the elements
of 1) with some function e.g. sum
For instance i got:
1) [ { 'g1' : 1, 'g2' : 8, 's_v1' : 5.0, 's_v2' : 3.5 },
{ 'g1' : 1, 'g2' : 9, 's_v1' : 2.0, 's_v2' : 3.0 },
{'g1' : 2, 'g2' : 8, 's_v1' : 6.0, 's_v2' : 8.0}, ... ]
2) ['g1', 'g2']
3) ['s_v1', 's_v2']
To be precise 1) is a result of a values_list method from a QuerySet
in Django; 2) is the arguments for that method; 3) those are the
annotation keys. so 1) is a result of:
qs.values_list('g1', 'g2').annotate(s_v1=Sum('v1'), s_v2=Sum('v2'))
What i want to have is:
a big nested dictionary with 'g1' values as 1st level keys and a
dictionary of aggregates and subgroups in it.
In my example it would be something like this:
{
1 : {
's_v1' : 7.0,
's_v2' : 6.5,
'g2' :{
8 : {
's_v1' : 5.0,
's_v2' : 3.5 },
9 : {
's_v1' : 2.0,
's_v2' : 3.0 }
}
},
2 : {
's_v1' : 6.0,
's_v2' : 8.0,
'g2' : {
8 : {
's_v1' : 6.0,
's_v2' : 8.0}
}
},
...
}
# notice the summed values of s_v1 and s_v2 when g1 == 1
I was looking for a solution that would let me do that kind of
grouping with variable lists of 2) and 3) i.e. having also 'g3' as
grouping element so the 'g2' dicts could also have their own
subgroup and be even more nested then.
I was trying something with itertools.groupby and updating nested
dicts, but as i was writing the code it started to feel too verbose to
me :/
Do You have any hints maybe? because i'm kind of stucked :/

Sławek
Not super-efficient, but simple:
$ cat python sumover.py
cat: python: No such file or directory
data = [ { 'g1' : 1, 'g2' : 8, 's_v1' : 5.0, 's_v2' : 3.5 },
{ 'g1' : 1, 'g2' : 9, 's_v1' : 2.0, 's_v2' : 3.0 },
{'g1' : 2, 'g2' : 8, 's_v1' : 6.0, 's_v2' : 8.0}]
sum_over = [s_v1, s_v2]
group_by = [g1, g2]
wanted = {
1 : {
's_v1' : 7.0,
's_v2' : 6.5,
'g2' :{
8 : {
's_v1' : 5.0,
's_v2' : 3.5 },
9 : {
's_v1' : 2.0,
's_v2' : 3.0 }
}
},
2 : {
's_v1' : 6.0,
's_v2' : 8.0,
'g2' : {
8 : {
's_v1' : 6.0,
's_v2' : 8.0}
}
},
}
def calc(data, group_by, sum_over):
tree = {}
group_by = group_by + [None]
for item in data:
d = tree
for g in group_by:
for so in sum_over:
d[so] = d.get(so, 0.0) + item[so]
if g:
d = d.setdefault(g, {}).setdefault(item[g], {})
return tree
got = calc(data, group_by, sum_over)[group_by[0]]
assert got == wanted
$ python sumover.py
$
Untested.
Very clever. I didn't understand how it worked until I rewrote it like
this:
def calc(data, group_by, sum_over):
tree = {}
group_by = [None] + group_by
for item in data:
d = tree
for g in group_by:
if g:
d = d.setdefault(g, {}).setdefault(item[g], {})
for so in sum_over:
d[so] = d.get(so, 0.0) + item[so]
return tree
Processing None in the last round of the loop was throwing me off.

If you open the file in universal newline mode with
with open(filename, U) as f:
bulk = f.read()
your data will only contain \n. You can then split with
blocks = bulk.split(\n\n) # exactly one empty line
or
blocks = re.compile(r\n{2,}).split(bulk) # one or more empty lines
One last variant that doesn't read in the whole file and accepts lines with
only whitespace as empty:
with open(filename, U) as f:
blocks = (.join(group) for empty, group in itertools.groupby(f,
key=str.isspace) if not empty)

Those are standard Python functions. You can run this on most server-type machines. It's best if you have an upstream server configured to do spam filtering and forwarding to your server, or you'll get vast amounts of junk coming into your system. Have the upstream machine forward to a nonstandard mail port (like example.com:2525) if the server machine already has a mail server. This will allow the existing mail server to run.

smtpd bug?
I've been using smtpd.py to implement a kind of cowboy SMTP server (only overriding process_message), and inevitably after a certain time the server stops accepting incoming connections: the socket on which it was formerly listening gets closed. I ran it using strace and discovered that it would get ENOTCONN on some just-accepted socket in a call to getpeername(), and then close the *listening* socket. This seems to be caused by the line channel = SMTPChannel(self, conn, addr) in smtpd.py and handle_error() in the definition of asyncore.dispatcher, which finishes by calling self.handle_close() [1]. The result of this is that when the call to getpeername() in the constructor for SMTPChannel raises ENOTCONN (or any other exception), it unwinds via asyncore.dispatcher.handle_read_event(), to asyncore.read(), where the SMTPServer instance gets its handle_error method called on it, eventually closing its listening socket. But the error was in the socket we just accepted---not the listening socket. [1] I'm actually using python2.4, since that's what's installed on the server; there, the handle_error() method simply finishes by calling self.close(). In fact, AFAICT, there's another problem in 3.1: neither asyncore.dispatcher nor smtpd.SMTPServer (nor any of its subclasses in smtpd.py) defines a method handle_close(); asyncore.dispatcher passes attribute lookups to its socket object via __getattr__, but sockets don't have a handle_close method either---so it seems as if, if handle_close() is ever called, it'll just generate a new error. -- http://mail.python.org/mailman/listinfo/python-list

[issue11128] decimal.py: to_integral() corner cases
Stefan Krah stefan-use...@bytereef.org added the comment: For the record, I prefer Python's behavior. The quantize() definition does not work well for arbitrary precision input and leads to situations like: Precision: 1 Maxexponent: 1 Minexponent: -1 tointegral 101 - 101 tointegral 101.0 - NaN Invalid_operation A comment in tointegral.decTest suggests that the to-integral definition was modeled after IEEE 854 and 754r: -- This set of tests tests the extended specification 'round-to-integral -- value' operation (from IEEE 854, later modified in 754r). -- All non-zero results are defined as being those from either copy or -- quantize, so those are assumed to have been tested. -- Note that 754r requires that Inexact not be set, and we similarly -- assume Rounded is not set. This definition of course works fine as long as the input does not have more than 'precision' digits and Emax is sufficiently large. I think that for arbitrary precision input the definition should read: Otherwise (the operand has a negative exponent) the result is the same as using the quantize operation using the given operand as the left-hand-operand and 1E+0 as the right-hand-operand. For the purpose of quantizing a temporary context is used with the precision of the operand as the precision setting, Emax = prec and Emin = -Emax. The rounding mode is taken from the context, as usual. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11128 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue11140] Error in the documentation of threading.Lock().release()
New submission from aaugustin aymeric.augus...@polyconseil.fr: The docs for the threading module state that: The release() method should only be called in the locked state; it changes the state to unlocked and returns immediately. If an attempt is made to release an unlocked lock, a RuntimeError will be raised. However, I noticed that catching RuntimeError does not work. Actually release() raises thread.error, which inherits directly Exception. I reproduced the behavior shown below in Python 2.6.6, 2.7.1 from MacPorts on Mac OS 10.6 and in Python 2.6.6 on Linux. The same happens in Python 3.2rc2 on Mac OS 10.6, except the thread module has been renamed to _thread so the exception becomes a _thread.error. import threading try: ... threading.Lock().release() ... except RuntimeError: ... pass ... Traceback (most recent call last): File stdin, line 2, in module thread.error: release unlocked lock try: ... threading.Lock().release() ... except Exception, e: ... print type(e) ... print type(e).mro() ... class 'thread.error' [class 'thread.error', type 'exceptions.Exception', type 'exceptions.BaseException', type 'object'] I do not know if this must be fixed in the docs or the code.

Unfortunately, I do not know how you would redefine ThreadError to extend RuntimeError in a C extension. _thread.error is created line 741 in trunk/Modules/threadmodule.c: ThreadError = PyErr_NewException(thread.error, NULL, NULL); I was not proposing to extend it, just to alias it: ThreadError = PyExc_RuntimeError; Py_INCREF(ThreadError); That said, extending is quite trivial if the behaviour is not changed: ThreadError = PyErr_NewException(thread.error, PyExc_RuntimeError, NULL); (see http://docs.python.org/dev/c-api/exceptions.html#PyErr_NewException) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11140 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue11139] subprocess: Arguments to .bat scripts get interpreted by shell
Arve Knudsen arve.knud...@gmail.com added the comment: Would you mind defining why the 2.7 behaviour is correct in this particular case? The list2cmdline behaviour discussed in issue 8972 has to do with shell commandlines; in this case, in my eyes any shell invocation (in order to run a .bat I guess) is only an implementation detail. Is the 2.7 behaviour correct since the Win32 function CreateProcess happens to start a shell to run .bat files, which in turn interprets the arguments? I'm guessing this is what happens... There certainly can't be any universal definition in subprocess saying that arguments to shell scripts shall be interpreted by the shell; when trying now *on Linux* to launch a corresponding .sh script through subprocess, arguments are passed through verbatim. I should like to see subprocess maintain (or keep maintaining, rather) a uniform interface, so that arguments are not interpreted so long as the 'shell' argument equals False. I understand completely that list2cmdline should implement C library behaviour, and not protect arguments from the shell, but that doesn't mean it should automatically define the behaviour of other functions such as Popen and call.

[issue11139] subprocess: Arguments to .bat scripts get interpreted by shell
Arve Knudsen arve.knud...@gmail.com added the comment: I wasn't saying that subprocess is interpreting the arguments, but that the shell is. Which was highly unexpected to me when outside of shell mode (i.e., shell == False). From some further testing, though, I see that the transformation from sequence to command line on Windows plays a bigger role than I was aware of even though I've used subprocess since it was introduced in the standard library. That is, I see that also in Python 2.6, arguments to .bat scripts get interpreted if command arguments are passed to subprocess as a string rather in a list. My current conclusion is that there has been a hole in the subprocess design the whole time, so that my case (start a Windows shell script like an executable) has just worked by chance, due to that I have passed arguments as a list which then got implicitly protected (even outside of shell mode). Maybe subprocess.Popen should take another option to implement the old behaviour of protecting arguments supplied as a list, given that this should be a common enough case?

[issue11145] '%o' % user-defined instance
New submission from Armin Rigo ar...@users.sourceforge.net: The expression '%o' % x, where x is a user-defined instance, usually ignores a user-defined __oct__() method. I suppose that's fine; assuming this is the expected behavior, then the present issue is about the usually in my previous sentence. If 'x' is an instance of a subclass of 'long', then the __oct__() is called. It must be specifically a 'long' -- not, say, 'int' or 'str' or 'object'. Moreover, there is a test in test_format.py (class Foobar) that checks that if this __oct__() returns a non-string, then we get a nice TypeError. That's already strange -- why is __oct__() called in the first place? But trying out more I get (CPython 2.7.1): class X(long): ... def __oct__(self): ... return 'abc' ...

[issue11146] Add a feature similar to C++ using some_namespace
New submission from Manuel Bärenz man...@enigmage.de: In C++, the the approach to the namespace problem is having different namespaces that should not contain different definitions of the same name. Members of a namespace can be accessed explicitly by e.g. calling std::cout etc. or using namespace std; cout etc. I understand Pythons approach to be objects can be used as namespaces and their attributes are the names they contain. I find this a very beautiful way of solving the issue, but it has a downside, in my opinion, because it lacks the using directive from C++. If the object is a module, we can of course do from mymodule import spam, eggs. But if it is not a module, this does not work. Consider for example: class Spam(object): def frobnicate(self): self.eggs = self.buy_eggs() self.scrambled = self.scramble(self.eggs) return self.scrambled 42 This could be easier to implement and read if we had something like: class Spam(object): def frobnicate(self): using self: eggs = buy_eggs() scrambled = scramble(eggs) return scrambled 42 Of course this opens a lot of conceptual questions like how should this using block behave if self doesn't have an attribute called eggs, but I think it is worth considering. -- messages: 128153 nosy: turion priority: normal severity: normal status: open title: Add a feature similar to C++ using some_namespace type: feature request ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11146 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Stefan Krah stefan-use...@bytereef.org added the comment: Chris Lambacher rep...@bugs.python.org wrote: I was cross-compiling to a target architecture that does not support the -march option so I would not be able to provide a different one as override. Just out of curiosity: You are cross-compiling a C-extension? How can you be sure that all values in pyconfig.h are correct? The debian-sysconfig-flags looks the most correct because it allows override at any point by emulating the CFLAGS = $(BASECFLAGS) $(OPT) $(EXTRA_CFLAGS) logic. It still looks like it needs an override for EXTRA_CFLAGS and the logic for LD_SHARED looks wrong. In the Makefile LDSHARED is just: LDSHARED= $(CC) -shared -Wl,-O1 -Wl,-Bsymbolic-functions I think Antoine is correct: EXTRA_CFLAGS show up as an empty string in sysconfig (even if passed to configure and make), so there is no need to override them. As an aside, why do EXTRA_CFLAGS still exist in py3k when CFLAGS can already be passed to configure and make? I agree that the ldshared logic looks wrong. It is possible to specify LDFLAGS via the environment, so why append CFLAGS. Changing this could break existing build scripts though. However, I don't see how the Debian patch could break anything, unless someone relies on the fact that BASECFLAGS are suppressed in case CFLAGS are given. I think the odds of this are virtually zero. Any interest in a cleaned up version of the Debian patch (remove double opt, line length, add documentation for overriding BASECFLAGS and OPT)? I'm asking, since I'm unsure about the degree of frozenness of distutils. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue969718 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
