[issue15024] Split enhanced assertion support out as a unittest.TestCase base class
New submission from Nick Coghlan ncogh...@gmail.com: The unittest module has some lovely enhanced comparison operations, but they're currently hard to access outside a test run. It would be rather convenient if they were split out into a separate base class so they could be used directly without needing to create an actual test case. Possible API: class Assertions: # All the enhanced assertion machinery goes here # Nothing related to actually running test cases class TestCase(Assertions): # This adds support for setUp, tearDown, addCleanup etc, etc My current workaround is to just define a dummy runTest method in a subclass and use that: class Assertions(unittest.TestCase): ... def runTest(self): pass ... check = Assertions() check.assertEqual([], ()) Traceback (most recent call last): File stdin, line 1, in module File /usr/lib64/python2.7/unittest/case.py, line 511, in assertEqual assertion_func(first, second, msg=msg) File /usr/lib64/python2.7/unittest/case.py, line 504, in _baseAssertEqual raise self.failureException(msg) AssertionError: [] != () check.assertEqual([1], [2]) Traceback (most recent call last): File stdin, line 1, in module File /usr/lib64/python2.7/unittest/case.py, line 511, in assertEqual assertion_func(first, second, msg=msg) File /usr/lib64/python2.7/unittest/case.py, line 740, in assertListEqual self.assertSequenceEqual(list1, list2, msg, seq_type=list) File /usr/lib64/python2.7/unittest/case.py, line 722, in assertSequenceEqual self.fail(msg) File /usr/lib64/python2.7/unittest/case.py, line 408, in fail raise self.failureException(msg) AssertionError: Lists differ: [1] != [2] First differing element 0: 1 2 - [1] + [2] -- messages: 162463 nosy: michael.foord, ncoghlan priority: normal severity: normal status: open title: Split enhanced assertion support out as a unittest.TestCase base class ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15024 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue10037] multiprocessing.pool processes started by worker handler stops working
Ask Solem a...@celeryproject.org added the comment: Well, I still don't know exactly why restarting the socket read made it work, but the patch solved an issue where newly started pool processes would be stuck in socket read forever (happening to maybe 1/500 new processes) This and a dozen other pool related fixes are in my billiard fork of multiprocessing, e.g. what you describe in your comment: # trying res.get() would block forever works in billiard, where res.get() will raise WorkerLostError in that case. https://github.com/celery/billiard/ Earlier commit history for the pool can be found in Celery: https://github.com/ask/celery/commits/2.5/celery/concurrency/processes/pool.py My eventual goal is to merge these fixes back into Python, but except for people using Python 3.x, they would have to use billiard for quite some time anyway, so I don't feel in a hurry. I think this issue can be closed, the worker handler is simply borked and we could open up a new issue deciding how to fix it (merging billiard.Pool or someting else). (btw, Richard, you're sbt?

[issue9256] plistlib should create non-naïve datetime objects
R.

Either way, a program using the plistlib is going to have to know about this and handle the distinction itself, since as you say datetime doesn't have a way to make this differentiation (other than naive vs aware).

[issue15028] PySys_SetArgv escapes quotes in argv[]
New submission from R.M.Bianchi riccardomaria.bian...@gmail.com:
Embedding Python in C++ I saw that if I pass this string below to the
PySys_SetArgv, as one of the command-line arguments passed to an embedded
script:
--net-label-name='(DC1,eth1)'
PySys_Argv transforms it escaping the single quotes, and in the Python side I
get this value for sys.argv[i]:
'--net-label-name=\'(DC1,eth1)\''
It does not seem a problem of converting strings or char in the C++ sides, I
checked them.
The problem appears just after the PySys_Argv call.
=== cut ===
Qt-Debug: python script command-line args:
(/afs/cern.ch/work/r/rbianchi/private/tdaq_4_0_0/dbe/cmt/pm_farm.py,
--safe-hw-tags, --add='pcatd143', --net-label-name='(DC1,eth1)',
newdb.data.xml)
[...]
pyout: sys.argv:
pyout:
pyout: ['/afs/cern.ch/work/r/rbianchi/private/tdaq_4_0_0/dbe/cmt/pm_farm.py',
'--safe-hw-tags', --add='pcatd143', '--net-label-name=\'(DC1,eth1)\'',
'newdb.data.xml']
=== cut ===
Please notice that the same script works perfectly with the same argument list
in stand-alone mode (i.e. not embedded in C++).
Please also notice that in the embedded side the problem does not appear if I
substitute the string passed as command line parameter from the original one:
--net-label-name='(DC1,eth1)'
to this one below, where I omit a level of quotes and I skip the double quotes:
--net-label-name=('DC1','eth1')
In this last case the embedded script also works fine in the embedded world.
It seems to me an issue in PySys_SetArgv, while parsing the strings. But maybe
I'm missing something.
Best regards,
R.M.Bianchi

[issue4442] document immutable type subclassing via __new__
Mateusz Loskot mate...@loskot.net added the comment: Is this report about documenting of the concept of immutable types in Python in general or regarding existing built-in types, like datetime.datetime? Generally, the concept of immutable type with relation to tp_new is mentioned (sneaked) here: 1) http://docs.python.org/release/3.2.2/c-api/typeobj.html A good rule of thumb is that for immutable types, all initialization should take place in tp_new, while for mutable types, most initialization should be deferred to tp_init. 2) http://www.python.org/dev/peps/pep-0253/ Note that for immutable object types, the initialization cannot be done by the tp_init() slot: this would provide the Python user with a way to change the initialization. Therefore, immutable objects typically have an empty tp_init() implementation and do all their initialization in their tp_new() slot. IMHO, it deserves a dedicated section/chapter in the docs. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4442 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue15029] Update Defining New Types chapter according to PEP 253
New submission from Mateusz Loskot mate...@loskot.net: The chapter '2. Defining New Types in the Python 3.2 documentation [1] does not cover all important elements, especially in the subsection 2.1.4. Subclassing other types. The accepted PEP 253 [2] provides much more detailed and thorough explanation for Python C API users willing to define and subclass new types, than the official manual. I'd like to suggest update of the manual with information enclosed in the PEP 253. In fact, the PEP's sections like * Preparing a type for subtyping * Creating a subtype of a built-in type in C could be copied with little editing, IMHO. The PEP 253 really seems to be a must-read document for Python C API users.

[issue15031] Split .pyc parsing from module loading
New submission from Ronan Lamy ronan.l...@gmail.com: I think it would be beneficial to extract the handling of the binary format of bytecode files from the rest of the loader/finder code in importlib._bootstrap. That means exposing, internally at least, functions that do nothing more than convert the binary contents of a .pyc file to/from metadata + code object. They would help in testing and implementing alternate loaders and would prevent the kind of code duplication that led to issue 15030. I'm adding a patch implementing extracting a _loads_pyc() function from _bytes_to_bytecode(). Note that: * _loads_pyc() has only one parameter, instead of 5 for _bytes_from_bytecode. * The raising of exceptions is more consistent: _loads_pyc being an IO helper, it never raises ImportError. Thanks to exception chaining, no information is lost, though. Obviously, this should be complemented with a _dumps_pyc(). Then there's the question of whether these functions should be public and what the best interface is - I actually feel that the natural home of both functions is in a lower level module, either imp or marshal. So, should I get on with it, or are there things I overlooked that make this a bad idea? -- components: Interpreter Core files: loads_pyc.diff keywords: patch messages: 162489 nosy: Ronan.Lamy, brett.cannon, ncoghlan priority: normal severity: normal status: open title: Split .pyc parsing from module loading type: enhancement versions: Python 3.3 Added file: http://bugs.python.org/file25860/loads_pyc.diff ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15031 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

It is about 10 times faster then using execv, and almost as fast as simple forking.) Ah, a working 'fork server' would be just as good. Btw, Billiard now supports running Pool without threads, using epoll/kqueue/select instead. So Celery uses that when it can be nonblocking, and execv when it can't. It performs way better without threads, and in addition shutdown + replacing worker processes is much more responsive. Changing the default Pool is not going to happen, but ncluding a simple select() based Pool would be possible, and then it could also easily work with Twisted, Eventlet, Gevent, etc. (especially now that the Connection is rewritten in pure python). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10037 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue10037] multiprocessing.pool processes started by worker handler stops working
Richard Oudkerk shibt...@gmail.com added the comment: Ah, a working 'fork server' would be just as good. Only problem is that it depends on fd passing which is apparently broken on MacOSX. Btw, Billiard now supports running Pool without threads, using epoll/kqueue/select instead. So Celery uses that when it can be nonblocking, and execv when it can't. It performs way better without threads, and in addition shutdown + replacing worker processes is much more responsive. If it were not for Windows I would have tried to avoid using threads. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10037 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15009] urlsplit can't round-trip relative-host urls.
Ankit Toshniwal ankitoshni...@gmail.com added the comment:
Hello,
Did some initial investigation, so looks like as per the code in parse.py,
under the function urlunsplit, we take the 5-tuple returned by urlsplit . In
the case of foo we get:
SplitResult(scheme='yelp', netloc='', path='/foo', query='', fragment='')
Now this tuple is passed to urlunsplit. We have a if statement under the
urlunsplit function
if netloc or (scheme and scheme in uses_netloc and url[:2] != '//'):
which checks if the netloc exists in the url (in our case it does not) then we
check if the scheme in the url is part of the uses_netloc list (predefined list
in parse.py with the list of common types of schemes used like http, ftp, file,
rsync etc). In our case since yelp is not part of it we fail at the if
statement and then we just return the url instead of modifying it. What we need
was that if the above statement fails we do an else which does something like
this:
if netloc or (scheme and scheme in uses_netloc and url[:2] != '//'):
if url and url[:1] != '/':
url = '/' + url
url = '//' + (netloc or '') + url
else:
if url and url[:1] != '/':
url = '/' + url
url = '//' + (netloc or '') + url
In that case we get the right url back.
After changing the code here is what i get on local dev machines:
urlunparse(urlparse('yelp:///foo'))
'yelp:///foo'
urlunsplit(urlsplit('file:///tmp'))
'file:///tmp'
urlunsplit(urlsplit('yelp:///foo'))
'yelp:///foo'
Thanks,
Ankit.
P.S : I am new to python trying to learn it and also work on small projects let
me know what you think if this is the right approach.

[issue15009] urlsplit can't round-trip relative-host urls.
Buck Golemon b...@yelp.com added the comment:
Well i think the real issue is that you can't enumerate the protocals that use
netloc. All protocols are allowed to have a netloc. the smb: protocol
certainly does, but it's not in the list.
The core issue is that smb:/foo and smb:///foo are different urls, and should
be represented differently when split. The /// form has a netloc, it's just the
empty-string. The single-slash form has no netloc, so I propose that
urlsplit('smb:/foo') return SplitResult(scheme='smb', netloc=None, path='/foo',
query='', fragment='')

[issue12510] IDLE: calltips mishandle raw strings and other examples
Terry J. Reedy tjre...@udel.edu added the comment:
I decided to commit the current patch (i12510c.test.diff + NEWS changes) as is.
Another change is needed to correctly delete the first arg of all methods, not
just instance methods with the first arg named 'self'. (In the current new
classmethod test, I just allowed non-removal of 'cls'. There should also be a
test with a variant of 'self'.)
In _self_pat = re.compile('self\,?\s*'), 'self' in the pattern should be
replaced by '(xxx', where 'xxx' is the pattern that matches an identifier. (And
add '(' to the replacement pattern.) If anyone can quickly tell me what that
is, that would be helpful.

Specifying it results in ENOTSUP every time. os.chmod() now accomodates this; it throws NotImplementedError if it detects this situation. However it should also Just Work once glibc supports it. * While editing the docstrings, I noticed that several of them had old-style octal constants ;-) I fixed 'em. * I added support for the remove_dir argument to unlink/remove on Windows.

[issue15031] Split .pyc parsing from module loading
Brett Cannon br...@python.org added the comment: So the problem with the function is that had this been implemented in Python 3.2 it already would be outdated thanks to the 3.3 change of storing the file size in the .pyc file, and simply changing the length of the sequence returned would probably break code.
