[issue12126] incorrect select documentation
Eli Bendersky eli...@gmail.com added the comment: This issue Jean-Paul raises seems to be a plain error. select() certainly can return that some given socket is both readable and writable (this is explicitly discussed in Steven's APitUE $14.5), and I see no evidence in the implementation of Python's selectmodule.c that it somehow violates the output of system's select() to behave otherwise. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12126 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue1441530] socket read() can cause MemoryError in Windows
Charles-François Natali neolo...@free.fr added the comment: It's actually an obvious case of heap fragmentation due to long-lived chunks being realloc()ed to a smaller size. Some malloc implementations can choke on this (e.g. OS-X's malloc is known to not shrink blocks when realloc() is called with a smaller size). The solution is simply to use a StringIO to avoid holding references to those blocks for too long.

[issue12126] incorrect select documentation
Antoine Pitrou pit...@free.fr added the comment: Well, my main issue with this document is that it doesn't seem to have a well-defined destination: - people who know sockets won't learn anything from it - but people who don't know sockets will probably find it clear as mud (for example, what's an INET or STREAM socket? what's select?) I have other issues, such as the style/tone it's written in. I'm sure the author had fun writing it but it doesn't fit well with the rest of the documentation. Also, the author gives a lot of advice without really giving an example (if somewhere in those input lists of sockets is one which has died a nasty death, the select will fail - is that really true? what is a nasty death and how is that supposed to happen? couldn't the author have put a 3-line example to demonstrate this supposed drawback and how it manifests?). And, finally, many statements seem arbitrary (There’s no question that the fastest sockets code uses non-blocking sockets and select to multiplex them) or plain wrong (threading support in Unixes varies both in API and quality. So the normal Unix solution is to fork a subprocess to deal with each connection). I don't think giving misleading advice to users is really a good idea. And suggesting beginners they use non-blocking sockets without even *showing* how (or pointing to asyncore or Twisted) is a very bad idea. select() is not enough, you still have to be prepared to get EAGAIN or EWOULDBLOCK when calling recv() or send() (i.e. select() can give false positives). Oh and I think it's obsolete too, because the class mysocket concatenates the output of recv() with a str rather than a bytes object. Not to mention that features of the class mysocket can be had using a buffered socket.makefile() instead of writing custom code. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12126 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue5715] listen socket close in SocketServer.ForkingMixIn.process_request()
Charles-François Natali neolo...@free.fr added the comment: Thanks for reporting this, the current behaviour is clearly wrong. The child process doesn't need to - and shouldn't - inherit the server socket. The custom idiom when writting such code is to close the new socket (well, in TCP) in the parent process, and close the server socket in the child process. That's what the attached patch does. Since I really doubt anyone using socketserver ever used the server's socket from the handler, this shouldn't be a problem for existing code (and the server's socket was never documented to be usable from the request handler). -- keywords: +needs review, patch nosy: +charles-francois.natali, haypo stage: test needed - patch review Added file: http://bugs.python.org/file22045/ss_fork_close.diff ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue5715 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

+
+ The POSIX standart requires that :c:func:`fsync` must transfer the buffered
+ data to the storage device, not that the data is actually written by the
+ device itself. It explicitely leaves it up to operating system implementors
+ whether users are given stronger guarantees on data integrity or not. Some

In case of error (e.g. timeout error), urllib.request leaves the socket open:
import urllib.request as ur
import socket
s = socket.socket()
s.bind(('localhost', 1))
s.listen(0)
socket.setdefaulttimeout(5)

During handling of the above exception, another exception occurred:

AFAIU, when urlopen returns or raises, the socket can be closed, so the
attached patch adds a finally that calls close() on the HTTPConnection
object. The test suite pass (except for a mock that was missing the close
method), but I'm not 100% sure that it's always safe to call close().
This ResourceWarning has been exposed by test_packaging.

The code in the first message does more or less the same, causing a timeout error and the resource warning.

[issue12134] json.dump much slower than dumps
New submission from poq p...@gmx.com:
import json, timeit
obj = [[1,2,3]*10]*10
class writable(object):
def write(self, buf): pass

print('dumps: %.3f' % timeit.timeit(lambda: json.dumps(obj), number=1))
print('dump: %.3f' % timeit.timeit(lambda: json.dump(obj,w), number=1))
On my machine this outputs:
dumps: 0.391
dump: 4.501
I believe this is mostly caused by dump using JSONEncoder.iterencode without
_one_shot=True, resulting in c_make_encoder not being used.

[issue1441530] socket read() can cause MemoryError in Windows
Charles-François Natali neolo...@free.fr added the comment:
Patch looks ok. Is 3.x also affected? The I/O stack changed quite a bit in
3.x.
I think it's not affected, but I can't reproduce this behaviour with
glibc/eglibc, so don't just take my word for it.
The reason is that in py3k, imaplib uses a buffered reader to read
from the socket (obtained through sock.makefile()), and IIUC, reading
from a buffered reader n bytes will always return n bytes (unless EOF
is encountered or the underlying object is set to non-blocking),
contrarily to reading directly from a socket. So the resizing is done
from the buffered io module, which only grows the result buffer,
freeing the buffers returned by socket's recv() one at a time.
Note that if I'm right, another way to solve this would be to wrap the
SSL socket with a call to makefile, like what's already done for the
non-SSL case (and in py3k). This would also lead to cleaner and
simpler code, because we wouldn't need to handle partial reads
ourself.
That's what the patch attached does.
Note that if I'm correct, then the current py3k imaplib read() method
could also be simplified:
def read(self, size):
Read 'size' bytes from remote.
chunks = []
read = 0
while read size:
data = self.file.read(min(size-read, 4096))
if not data:
break
read += len(data)
chunks.append(data)
return b''.join(chunks)
It would also be a bit faster.
But since I can't reproduce this issue, I'd rather make sure it's
correct before making a such change.

IEEE 754 is not a standard that is directly applicable to the design of programming languages. For example, it is completely silent on the issue of which operations should be implemented as infix operators and which as functions. Still, to the extent it is appropriate for IEEE 754 to say so, I think it says that '' is 'compareSignalingLess'. IEEE 754 can only be a guide for language design and not a specification. However, the decimal module, which was explicitly designed for IEEE 754 compliance, makes order comparison operators signaling. What is the reason to make them quiet for floats other than backward compatibility?

[issue11949] Make float('nan') unorderable
Mark Dickinson dicki...@gmail.com added the comment: What is the reason to make them quiet for floats other than backward compatibility? For me, none. I'll happily agree that, all other things being equal, it's more natural (and more consistent with other languages) to have correspond to the signaling operation, and in a new language that's probably what I'd go for. But as a *change* to existing behaviour in a language that's been widely adopted for numerical work, the risk of breakage seems to me to outweigh any benefits. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11949 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue12127] Inconsistent leading zero treatment
Mark Dickinson dicki...@gmail.com added the comment: It does look as though all the arguments were pretty thoroughly hashed out on the python-3000 list when this was first proposed. See e.g., the thread starting at: http://mail.python.org/pipermail/python-3000/2007-March/006262.html and various follow-on threads. I retract my suggestion that this should be discussed again on python-dev; it probably wouldn't achieve anything. On the subject of other languages, I was rather hoping that more recent and enlightened languages would have done away with the leading zero implies octal business. It looks as though C# has, at least, but I was a bit disappointed to see that Go still has leading-zero octal literals. For the old-school languages, I'd still expect that for most users this feature is more often a surprising gotcha than expected and useful. http://stackoverflow.com/questions/565634/integer-with-leading-zeroes Anyway, +0 for closing as 'rejected'.

That might be viable (a math module function might also make sense here), though it feels a bit YAGNI to me. I have to admit that it would be YAGNI for most of my code because it uses numpy for numeric calculations. Still, for consistency with decimal, it may be a good addition. Going a bit off-topic, I would like to mention the feature that may actually be quite useful: float.sorting_key() that will return an integer for each float in such a way that keys are ordered in IEEE 754 total ordering. Note that decimal has compare_total() that can be used for sorting, but a cmp-style method is less useful than a key since in py3k sort does not take cmp function anymore. Nice thing about IEEE 754 is that float.sorting_key() can be implemented very efficiently because one can simply use float's binary representation interpreted as an integer for the key. If we were going to add such a method, it should follow IEEE 754: nan.max(x) == x.max(n) == x, but also nan.min(x) == x.min(nan) == x, for finite x. (See section 5.3.1.) Agree. Unfortunately, numpy does not do it that way: nan maximum(1.0, nan) nan I am not sure whether this is an argument for or against float.max/min: if numpy had properly defined maximum, I would just recommend to use that. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11986 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

New submission from Tarek Ziadé ziade.ta...@gmail.com:
this test module looks for sysconfig.get_config_var('srcdir') which in turns
uses the sys,executable path.
multiprocess seems to change it in every process, leading to the errors.
To reproduce:
./python Lib/test/regrtest.py -j2 -v test_packaging
A workaround is to skip the test in case the file is not found, but we need to
fix it because it boils down to sysconfig being broken in multiprocess

And this is done like this:
if sys.executable:

else:
# sys.executable can be empty if argv[0] has been changed and Python is
# unable to retrieve the real program name
_PROJECT_BASE = _safe_realpath(os.getcwd())
Because sys.executable (argv[0] in fact) is not filled when you call

So yeah, this has to do with sys.executable

Because sys.executable (argv[0] in fact) is not filled when you call

sys.executable is set perfectly well when running regrtest in
multiprocess mode, otherwise many other tests would fail.
Try:
$ grep sys.executable Lib/test/*
Lib/test/regrtest.py:585:base_cmd = [sys.executable] + opt_args +
['-m', 'test.regrtest']
Lib/test/script_helper.py:20:cmd_line = [sys.executable]

args
Lib/test/test_capi.py:42:p = subprocess.Popen([sys.executable, -c,

Again, it seems sysconfig simply has a bug which you can reproduce on
the command line:

I also don't see that library in the build tree. Instead, the library is built as python3.3dm (the buildbot process uses --with-pydebug and --with-pymalloc is now default in 3.2+). Haven't dug much deeper than that, so not sure how the packaging tests are figuring out the shared library to link with. I did verify that the sysconfig module variables that are related do all have the dm suffix information so it should be available to the tests. -- David -- nosy: +db3l ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12143 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue6560] socket sendmsg(), recvmsg() methods
Brian May br...@microcomaustralia.com.au added the comment: What needs to happen to get recvmsg() supported in Python? recvmsg() is required to get get transparent UDP proxies working under Linux using tproxy, the code needs to run recvmsg() to be able to find out what the original destination address was for the the packet.

[issue12144] cookielib.CookieJar.make_cookies fails for cookies with 'expires' set
New submission from Scott Wimer scott.wi...@gmail.com: When cookielib.CookieJar().make_cookies is used to extract cookies from a urllib2 response, it crashes when it encounters a 'Set-Cookie' header entry that has an 'expires' attribute. This crash occurs because the expires time is evaluated against the '_now' attribute of the CookieJar instance -- an attribute which is not set unless CookieJar().extract_cookies() was called previously. Attached is a script that triggers this bug. -- components: Library (Lib) files: cookielib-crash.py messages: 136497 nosy: Scott.Wimer priority: normal severity: normal status: open title: cookielib.CookieJar.make_cookies fails for cookies with 'expires' set type: crash versions: Python 2.6 Added file: http://bugs.python.org/file22054/cookielib-crash.py ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12144 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue12144] cookielib.CookieJar.make_cookies fails for cookies with 'expires' set
Scott Wimer scott.wi...@gmail.com added the comment: The actual error is triggered by line 1507 in '_cookie_from_cookie_tuple()'. An easy fix is to move the setting of '_now' on line 1636 into the 'make_cookies()' method. That addresses this problem and doesn't look like it would introduce any negative side effects. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12144 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue12145] distutils2 should support README.rst
