[issue13376] readline: pre_input_hook not getting called
Ned Deily n...@acm.org added the comment: Since you mention 2.7.1, presumably you are using the Apple-suppled Python 2.7.1 in OS X. That Python is not linked with GNU readline, rather the BSD libedit library. As a workaround you could try installing the third-party readline package from PyPI which replaces the Python redline module with one that is statically linked with GNU readline (see http://pypi.python.org/pypi/readline). On the other hand, if there are more differences in behavior between Python readline linked with GNU readline and with BSD libedit, they should be documented. -- nosy: +ned.deily ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13376 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Compute the maximum character requires to decode the full string. I prefer to work on a wchar_t* string to only decode surrogate pairs and computer the maximum character once. decode_code_page_errors() can also be called on a substring of a longer string, decode_code_page_strict() can be called for the other part. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13377 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue11682] PEP 380 reference implementation for 3.3
Nick Coghlan ncogh...@gmail.com added the comment: In reviewing Zbyszek's doc updates and comparing them against the Grammar, I discovered a gratuitous change in the implementation: it allows a bare (i.e. no parentheses) 'yield from' as an argument to a function, even when there's multiple arguments. By contrast, an ordinary yield expression requires parentheses everywhere other than when it's being used as a statement, or as the sole expression on the RHS of an assignment. I'll add a new test to ensure yield from x requires parentheses whenever yield x requires them (and fix the Grammar file on the implementation branch accordingly). I've also pushed a fix to the branch for the refleak Yury pointed out (once I actually ran regrtest in refleak hunting mode it also pointed out that there was a problem, so I know his suggested change definitely fixed it). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11682 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue11682] PEP 380 reference implementation for 3.3
Nick Coghlan ncogh...@gmail.com added the comment:
OK, the bitbucket repo now has a more sane version of the new Grammar ('yield
from' now requires parentheses wherever 'yield' does).
The updated test_grammar does a more thorough check of the expected acceptance
and rejection of yield expressions in various situations and the overly
sensitive test in test_parser (that checked for an exact expected parse tree
output) is gone.

[issue13093] Redundant code in PyUnicode_EncodeDecimal()
Stefan Krah stefan-use...@bytereef.org added the comment:
Looking at it again, the intention was probably to increment
collend so that it points to the first non-garbage character
(or '\0'). If that's the case, the loop should be something
like this:
while (collend end) {
if ((0 *collend *collend 256) ||
Py_UNICODE_ISSPACE(*collend) ||
Py_UNICODE_TODECIMAL(*collend) = 0)
break;
collend++;
}
I can understand if no one wants to touch this given that
the function is deprecated, provided that you agree that
the existing code is redundant but harmless; i.e. it cannot
enter an infinite loop.

[issue6397] Implementing Solaris /dev/poll in the select module
Jesús Cea Avión j...@jcea.es added the comment:
They are operations potentially slow, there are not realtime specifications.
My machine is quite capable (16 CPUs), but let's see what a bit of DTRACE
scripting tells us:
First, let's time the open:
syscall::open*:entry
/copyinstr(arg0)==/dev/poll/
{
self-ts = timestamp;
}
syscall::open*:return
/self-ts/
{
@stats = quantize(timestamp-self-ts);
self-ts = 0;
}
The result, times in nanoseconds:
value - Distribution - count
2048 | 0
4096 | 4497743
8192 | 17358
16384 | 1592
32768 | 2046
65536 | 812
131072 | 374
262144 | 0
Most opens finish in 4 microseconds, but we have a handful of slow openings
of hundred of microseconds.
Anyway, argueing with the GIL here is a nonissue, since the open is only done
at object creation, and a sane program will only create a handful of devpoll
objets.
Let's see now the write:
syscall::open*:entry
/copyinstr(arg0)==/dev/poll/
{
self-ts = timestamp;
}
syscall::open*:return
/self-ts/
{
@stats = quantize(timestamp-self-ts);
self-ts = 0;
}
The results for a single descriptor registered:
value - Distribution - count
256 | 0
512 | 4102701
1024 | 28514
2048 | 11269
4096 | 537
8192 | 245
16384 | 377
32768 | 193
65536 | 134
131072 | 71
262144 | 0
Most writes are really fast, half a microsecond, but we have sporadic latencies
of a hundred of microseconds.
Re-registering 200 sockets per loop, I have:
value - Distribution - count
512 | 0
1024 | 50
2048 | 94
4096 | 157
8192 |@@@ 1112314
16384 |@22977
32768 | 1584
65536 | 842
131072 | 168
262144 | 0
Most writes takes around 8 microseconds.
So now the problem is to estimate how much time I need to release readquire
the GIL. For that, and while we don't have DTRACE integration in python (my
next project, I hope), I change sourcecode to add a manual probe using the
Solaris High Resolution timers, I get a median time of around 550 nanoseconds
(half a microsecond), with a few spikes, when the GIL is not contested.
So, unlocking the GIL is adding around half microsecond to the syscalls. This
is fast, but comparable with the syscall actual duration. Liberating the GIL is
doubling the time to registerunregister a socket (supposely we are doing a
single socket per iteration, something realistic in real code).
Being realistic, any work we do with the descriptors (like actually reading or
writing it) is going to make this 0.5 microsecond gain pointless. Freeing the
GIL, we are protected of any kernel contention, and playing for the rules :-).
Anyway I am open to feedback.
PS: I also checked with GIL contention, and results are comparable. That is
surprising, maybe related to the GIL improvements in 3.3. I haven't
investigated the issue further.

Otherwise, it looks good... although I don't have currently access to a Solaris

No, but it's a Python error if Python wrongly assumes that write() won't
return a partial result. Ideally write() should be retried in a loop
until everything is written out.

Or maybe it wouldn't be worth the effort, since it would mean writing separate Windows implementations. Writing separate Windows versions has a long tradition in posixmodule.c, so in principle it's fine. It still may not be worth the effort since the function is deprecated in favor of the subprocess module.

Jesús Cea Avión j...@jcea.es added the comment: The problem with partial writes is that the data is not an unstructured stream of bytes, but a concrete binary dump. You can not simply retry again. My bet is that /dev/poll neves does partial writes. If I am mistaken, I will bug the Illumos people to help me to solve it. So far, this seems a theorical problema. Just in case it is not, we raise an exception and urge the programmer to report us the issue. The other option would be to try to be clever and do things like retrying if the partial write is a multiple of the struct size, but what if it not so?. Instead of guessing and play games, I rather prefer to know if this is actually a problem in the wild. In my tests, with 65530 sockets, I never saw this impossible exception. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue6397 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Nekmo nin...@gmail.com added the comment:
In my case, I have several clients, and they define the namespaces. I am
interested in return the same namespace that they gave me, for example, the
client A gives me this:
house:iq xmlns:house=http://localhost/house; /
To name the namespace, I set it at nsmap:
import xml.etree.ElementTree as etree
etree.register_namespace('house', 'http://localhost/house')
etree._namespace_map
{'http://localhost/house': 'house',
'http://purl.org/dc/elements/1.1/': 'dc',
'http://schemas.xmlsoap.org/wsdl/': 'wsdl',
'http://www.w3.org/1999/02/22-rdf-syntax-ns#': 'rdf',
'http://www.w3.org/1999/xhtml': 'html',
'http://www.w3.org/2001/XMLSchema': 'xs',
'http://www.w3.org/2001/XMLSchema-instance': 'xsi',
'http://www.w3.org/XML/1998/namespace': 'xml'}
Thus, keeping the name of the namespace:
etree.tostring(etree.Element('{http://localhost/house}iq'))
b'house:iq xmlns:house=http://localhost/house; /'
But if I have a client B, which uses a different name, and run in parallel,
problems can occur:
home:iq xmlns:home=http://localhost/house; /
import xml.etree.ElementTree as etree
etree.register_namespace('home', 'http://localhost/house')
etree._namespace_map
{'http://localhost/house': 'home',
'http://purl.org/dc/elements/1.1/': 'dc',
'http://schemas.xmlsoap.org/wsdl/': 'wsdl',
'http://www.w3.org/1999/02/22-rdf-syntax-ns#': 'rdf',

'http://www.w3.org/2001/XMLSchema-instance': 'xsi',
'http://www.w3.org/XML/1998/namespace': 'xml'}
Therefore, I ask that _namespace_map is within etree._Element instance, and not
global

However, I really do not know what all the attributes mean. (Should self-raw_pos also be modified...?) raw_pos is the position which the underlying raw stream is currently at. It only needs to be modified when a successful write(), read() or seek() is done on the raw stream. Another comment: you set errno to EAGAIN, but it is not sure that was the actual errno raised by the raw stream (although that's quite likely). You might want to reflect the actual C errno (but you'd better set it to 0 before the system call, then). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13322 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue13375] Provide a namedtuple style interface for os.walk values
Nick Coghlan ncogh...@gmail.com added the comment: Why provide any namedtuple interface in any context? After all, you can just unpack them to individual variables. The point is that the values produced by os.walk() *aren't* just an arbitrary 3-tuple - they have a definite API for describing a directory: the base path, then lists of relative names for any subdirectories and the relative names for any files. Why not make that explicit in the objects produced instead of leaving it as merely implied? This idea actually came out of the proposal for providing an itertools-inspired toolset for manipulating the output of os.walk() style iteration (#13229 and https://bitbucket.org/ncoghlan/walkdir/overview). I'll be adding this feature to walkdir regardless, but it seems to make more sense to offer it as standard behaviour. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13375 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Why not make that explicit in the objects produced instead of leaving it as merely implied? You could make this argument for any function that returns a tuple to return multiple distinct values. I claim that the API in this case is already simple enough that adding a nametuple does nothing but feature bloat. What does having a dirinfo object with attributes tell you that simply unpacking the tuple doesn't? You have to remember names in both cases.

[issue11427] ctypes from_buffer no longer accepts bytes
Meador Inge mead...@gmail.com added the comment: Hmmm... I take back what I said before (not sure what I was thinking), I don't think this is a regression. If this ever did work, it must have been a bug. For one reason, Python byte strings are now immutable. Allowing their memory to be indirectly mutated in Python via buffers created from 'from_buffer' would be very bad. Also, I can't reproduce the reported behavior with 3.1.3: Python 3.1.3 (unknown, Nov 9 2011, 19:57:58) [GCC 4.6.1 20110908 (Red Hat 4.6.1-9)] on linux2 Type help, copyright, credits or license for more information. import ctypes (ctypes.c_char*5).from_buffer(b'abcde') Traceback (most recent call last): File stdin, line 1, in module TypeError: expected an object with a writable buffer interface Are you sure it was 3.1.3? At first I thought you might be using 3.0a, since bytes are mutable in that version, but 'from_buffer' didn't exist in those times. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11427 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue13380] ctypes: add an internal function for reseting the ctypes caches
New submission from Meador Inge mead...@gmail.com: Currently it is possible to somewhat easily get false positives for reference leaks when running the ctypes regression tests with -R. See issue13250 for an example where I got tripped up. The reason is that the ctypes caches are not cleared in between test runs like they are with some of the other modules that cache objects. The attached patch adds an internal function for reseting the ctypes caches. regrtest.py is then fixed up to use it. Finally, two tests that previously relied on the caching being present to work in back-to-back runs have been fixed. In particular, the tests were written to do something like: # Global dll = CDLL(_ctypes_test.__file__) # Local to test f = dll._testfunc_callback_i_if f.restype = c_int MyCallback = CFUNCTYPE(c_int, c_int) def callback(value) return value cb = MyCallback(callback) result = f(-10, cb) f.argtypes = [c_int, MyCallback] cb = MyCallback(callback) result = f(-10, cb) Thus when run in back-to-back runs where caching is cleared in between you effectively get: # Global dll = CDLL(_ctypes_test.__file__) # Local to test f = dll._testfunc_callback_i_if f.restype = c_int MyCallback = CFUNCTYPE(c_int, c_int) def callback(value): return value cb = MyCallback(callback) result = f(-10, cb) f.argtypes = [c_int, MyCallback] cb = MyCallback(callback) result = f(-10, cb) _reset_cache() f = dll._testfunc_callback_i_if f.restype = c_int MyCallback = CFUNCTYPE(c_int, c_int) cb = MyCallback(callback) result = f(-10, cb) which causes: types.ArgumentError: argument 2: class 'TypeError': expected CFunctionType instance instead of CFunctionType because the final MyCallback instance passed to f is not of the same type as the MyCallback type saved in f.argtypes. The fix is to set f.argtypes to None at the beginning of each test. I would also like to commit this to 2.7 and 3.2. It will make fixing true reference leaks in those branches easier.
