[issue8493] socket's send can raise errno 35 under OS X, which causes problems in sendall
Charles-Francois Natali neolo...@free.fr added the comment: That's what I thought at first too. But the user's sockets were set to blocking. That's one broken networking stack... In fact, I think it's a little silly that OS X raises the error rather than just saying that 0 bytes were sent (which is what I suppose that other OSes do). Normal OS just block inside the send() call whenever socket buffers are full (unless there're set to non-blocking). So you can resume sending as soon as buffer space is available, and you don't have to resort to this send()/fail/sleep/re-send() scheme... But I think it's also not ideal that Python's socket.sendall() can't be used with confidence under OS X because it can fail under pretty normal circumstances. Agreed, but it's really a OS X issue here. How would you circumvent this problem anyway ? Add a timeout option to sendall() as a hint to how much we should wait before retrying when errno 35 is returned ? It would be really hacky... Maybe the user could try increasing SO_SNDBUF, but this won't necessarily solve his problem... @exarkun: ideas on this ? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8493 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue7946] Convoy effect with I/O bound threads and New GIL
Antoine Pitrou pit...@free.fr added the comment: Dave, In the current implementation, threads perform a timed-wait on a condition variable. If time expires and no thread switches have occurred, the currently running thread is forced to drop the GIL. A problem, as far as I can see, is that these timeout sleeps run periodically, regardless of the actual times at which thread switching takes place. I'm not sure it's really an issue but it's a bit of a departure from the ideal behaviour of the switching interval. A new attribute 'cpu_bound' is added to the PyThreadState structure. If a thread is ever forced to drop the GIL, this attribute is simply set True (1). If a thread gives up the GIL voluntarily, it is set back to False (0). This attribute is used to set up simple scheduling (described next). Ok, so it's not very different, at least in principle, from what gilinter.patch does, right? (and actually, the benchmark results look very similar) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7946 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

If you set a timeout on a socket, it is really non-blocking internally (from the OS' point of view). So perhaps this is what you are witnessing.

[issue8533] regrtest: use backslashreplace error handler for stdout
New submission from STINNER Victor victor.stin...@haypocalc.com: If a test fails, regrtest writes the backtrace to sys.stdout. If the backtrace contains a non-ASCII characters, it's encoded using sys.stdout encoding. In some conditions, sys.stdout is unable to encode some or all non-ASCII characters. Eg. if there is no locale set (empty environment or at least empty LANG variable value), sys.stdout.encoding=ascii. If regrtest fails to display a test output (error backtrace), regrtest exits directly (don't execute next tests). I propose to use backslashreplace error handler in sys.stdout, as done for sys.stderr to avoid this annoying issue. Attached patch (for py3k) replace sys.stdout by a new file using backslashreplace, just before executing the tests.

[issue7946] Convoy effect with I/O bound threads and New GIL
David Beazley d...@dabeaz.com added the comment: Greg, I like the idea of the monitor suspending if no thread owns the GIL. Let me work on that. Good point on embedded systems. Antoine, Yes, the gil monitor is completely independent and simply ticks along every 5 ms. A worst case scenario is that an I/O bound thread is scheduled shortly after the 5ms tick and then becomes CPU-bound afterwards. In that case, the monitor might let it run up to about 10ms before switching it. Hard to say if it's a real problem though---the normal timeslice on many systems is 10 ms so it doesn't seem out of line. As for the priority part, this patch should have similar behavior to the glinter patch except for very subtle differences in thread scheduling due to the use of the GIL monitor. For instance, since threads never time out on the condition variable anymore, they tend to cycle execution in a purely round-robin fashion. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7946 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

The functions would have to be called os.path.fsencode() and os.path.fsdecode(). Ok Other than that, I'm +0 on the patch: the sys.filesystemencoding logic doesn't really work well in practice - on Unix and BSD platforms, there's no such thing as a single system-wide file system Today, most POSIX system uses utf8 by default for all partitions. If you mount an USB key, CD-Rom or network shared directory with the wrong options, you may get filenames in a different encoding. But this issue is not about fixing your OS configuration, but helping the most common case: a system using the same encoding everywhere (for the whole file system). You are still free to use directly the native OS type (unicode on Windows, bytes on other OS), ie. don't use fsencode()/fsdecode(). Right, but if you start using those new API in standard lib functions, programmers no longer have that choice. In real life applications, you do run into these problems quite often, so instead of coding against an ideal world, we have to be aware of the problems and make it possible for the standard lib modules to deal with them. Python3 prefers unicode, eg. print expects an unicode string, not a byte string. I mean it's more pratical to use unicode everywhere in Python, and so fsencode()/fsdecode() can be really useful on POSIX systems.

To support byte strings on Windows, each Python function written in C should be fixed to use the ANSI version instead of the Wide version (eg. CreateProcessA instead of CreateProcessW) if it gets byte arguments. The code would become twice bigger, and it introduces new issues: which function should be choosen if there are two arguments, one is a byte string, and the other an unicode string? _subprocess.CreateProcess has 9 arguments... Since unicode is a superset of MBCS and MBCS has subtle bugs, it's preferable to use (force) unicode. -- But on POSIX, it's the opposite: I'm doing my best to support byte string everywhere (filenames, environment variables, etc.).

[issue8514] Create fsencode() and fsdecode() functions in os.path
STINNER Victor victor.stin...@haypocalc.com added the comment: Le lundi 26 avril 2010 13:06:48, vous avez écrit : I don't see what environment variables have to do with the file system. A POSIX system only offers *one* function about the encoding: nl_langinfo(CODESET) and Python3 uses it for the filenames, environment variables and the command line arguments. Are you suggesting that Python3 should support a encoding different for environment variables and the file system? How would the user configure it? About filenames, Python3 choose the encoding using the locale, but the user cannot change it: sys.setfilesystemencoding() is removed by the site module. Also note that mbcs on Windows is a meta-encoding. The implementation of that encoding depends on the locale used by the Windows user. It's just a coincidence that this may actually work for the environment variables on Windows as well, but there's no guarantee. os.getenv() should raise a TypeError on Windows if key is a byte string. os.getenv() didn't support byte string. I patched it to support byte string (issue #8391, r80421). But I don't like my fix because we should reject support byte string *on Windows*. I would like to factorize the type check for all operations on the file system and environment variables in fsencode()/fsdecode(). On Unix, you often have the case that the environment variables use mixed encodings, e.g. the CGI interface is a good example where this happens per definition. The CGI environment can includes file system paths, data encoded in Latin-1 (or some other encoding), etc. Since Python3 choosed to store environment variables as unicode string on Windows and POSIX, in this specific case you should reconvert the value to byte strings using fsencode() and then manipulate byte strings. Because Python3 uses surrogateescape, you will get the original byte string values. My patch should help both cases: people using unicode objects and people using the native OS type (bytes on POSIX). As written in my previous message, you can still use byte strings if you want. My patch doesn't change that (on POSIX systems). -- title: Create fs_encode() and fs_decode() functions in os.path - Create fsencode() and fsdecode() functions in os.path ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8514 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue8493] socket's send can raise errno 35 under OS X, which causes problems in sendall
Charles-Francois Natali neolo...@free.fr added the comment:
What is the mnemonic corresponding to errno 35 under OS X?
(under Linux I get EDEADLOCK, which probably isn't the right one)
From the first message: errno 35 (resource temporarily unavailable). It's
actually EAGAIN on Linux (which makes sense on a non-blocking socket).
By the way, rather than sleeping a fixed amount of time before retrying, you
could probably use select() on the socket.
select doesn't mean much for sockets you want to send to, because it will
report the socket in the writable set as soon as there's one byte free in the
send buffer, so you can very well block (or fail in that case) even when select
reports the socket as ready for writting.
If you set a timeout on a socket, it is really non-blocking internally (from
the OS' point of view). So perhaps this is what you are witnessing.
Yes. Maybe it would help to have the sample code ?
Googling a little bit gave this:
http://lists.freebsd.org/pipermail/freebsd-hackers/2004-January/005369.html
I have written a test program,
http://www.infres.enst.fr/~pook/send/server.c, that shows that send does
not block on FreeBSD. It does with Linux and Solaris.
Do you know what the behaviour of Net- and/or OpenBSD is?
NetBSD is the same as FreeBSD. I have not tested OpenBSD.
MacOS X is similiar to FreeBSD in that send doesn't block, howver
the send does not give an error: the packet is just thrown away.
So there seems to be an issue on some systems when you run out of socket
buffers, and since select doesn't seem to work either, I guess the only option
is this sleep-a-little-hoping-the-buffer-gets-drained approach.
I think this is a bug in Python's socket module.
recv()-like functions are written so as to first call select() before
actually receiving data, but send()-like functions aren't. I guess blocking
sends are quite rare thanks to in-kernel buffering, but we should do the
correct thing and use the same logic for send() as we do for recv().
When I look at trunk, I see this:
do {
timeout = internal_select(s, 1);
n = -1;
if (timeout)
break;
#ifdef __VMS
n = sendsegmented(s-sock_fd, buf, len, flags);
#else
n = send(s-sock_fd, buf, len, flags);
#endif
if (n 0) {
#ifdef EINTR
/* We must handle EINTR here as there is no way for
* the caller to know how much was sent otherwise. */
if (errno == EINTR) {
/* Run signal handlers. If an exception was
* raised, abort and leave this socket in
* an unknown state. */
if (PyErr_CheckSignals())
return NULL;
continue;
}
#endif
break;
}
buf += n;
len -= n;
} while (len 0);
we call internal_select(s, 1) (1 for writting) before sending.
But as I said, it's not reliable.

[issue7946] Convoy effect with I/O bound threads and New GIL
David Beazley d...@dabeaz.com added the comment: I've also attached a new file schedtest.py that illustrates a subtle difference between having the GIL monitor thread and not having the monitor. Without the monitor, every thread is responsible for its own scheduling. If you have a lot of threads running, you may have a lot of threads all performing a timed wait and then waking up only to find that the GIL is locked and that they have to go back to waiting. One side effect is that certain threads have a tendency to starve. For example, if you run the schedtest.py with the original GIL, you get a trace where three CPU-bound threads run like this: Thread-3 16632 Thread-2 16517 Thread-1 31669 Thread-2 16610 Thread-1 16256 Thread-2 16445 Thread-1 16643 Thread-2 16331 Thread-1 16494 Thread-3 16399 Thread-1 17090 Thread-1 20860 Thread-3 16306 Thread-1 19684 Thread-3 16258 Thread-1 16669 Thread-3 16515 Thread-1 16381 Thread-3 16600 Thread-1 16477 Thread-3 16507 Thread-1 16740 Thread-3 16626 Thread-1 16564 Thread-3 15954 Thread-2 16727 ... You will observe that Threads 1 and 2 alternate, but Thread 3 starves. Then at some point, Threads 1 and 3 alternate, but Thread 2 starves. By having a separate GIL monitor, threads are no longer responsible for making scheduling decisions concerning timeouts. Instead, the monitor is what times out and yanks threads off the GIL. If you run the same test with the GIL monitor, you get scheduling like this: Thread-1 33278 Thread-2 32278 Thread-3 31981 Thread-1 33760 Thread-2 32385 Thread-3 32019 Thread-1 32700 Thread-2 32085 Thread-3 32248 Thread-1 31630 Thread-2 32200 Thread-3 32054 Thread-1 32721 Thread-2 32659 Thread-3 34150 Threads nicely cycle round-robin.

[issue8493] socket's send can raise errno 35 under OS X, which causes problems in sendall
Charles-Francois Natali neolo...@free.fr added the comment: I don't see any evidence in support of this statement. From Microfost Windows' documentation: The parameter writefds identifies the sockets that are to be checked for writability. If a socket is processing a connect call (nonblocking), a socket is writeable if the connection establishment successfully completes. If the socket is not processing a connect call, writability means a send, sendto, or WSASendto are guaranteed to succeed. However, they can block on a blocking socket if the len parameter exceeds the amount of outgoing system buffer space available. It is not specified how long these guarantees can be assumed to be valid, particularly in a multithreaded environment. For the Linux kernel, a few years ago a socket would be returned as writable if it had a fixed amount of send socket buffer queue available, so if you send more than is available at that time, you're either going to block, or get an error (now the threshold is 1/2 of the used buffer space, but this doesn't change the problem). That's why I said it's not reliable. Did you notice that the FreeBSD thread you referenced is: * 6 years old * about UDP So ? It's not obvious to me that it's actually relevant here. I'm not saying that it's the source of the problem, I'm just saying that there's a record of send() calls failing on lack of socket buffers, on blocking sockets. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8493 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue8493] socket's send can raise errno 35 under OS X, which causes problems in sendall
Matthew Cowles mdcow...@users.sourceforge.net added the comment: [Replying to various posts] [neologix] That's one broken networking stack... I'm not disagreeing, but you'd have to take that up with Apple. How would you circumvent this problem anyway ? The code has to go around again in the case of an incomplete send. I imagine that it could go around again if the return value was -1 and errno was 35. Doing that in Python fixed the problem for the user. [pitrou] Matthew, can you confirm whether the socket had a timeout set to it? (either through settimeout() or setglobaltimeout()) I double- and triple-checked that the user wasn't setting a timeout. The problem came up in the context of the ftplib module and a look at the code (it was Python 2.6.2) suggests that that module doesn't set a timeout unless you ask it to.

[issue7583] Improve explanation of tab expansion in doctests
R. David Murray rdmur...@bitdance.com added the comment: The problem is that it would be equally reasonable for someone to want to put real tab characters in the output section (which results in strange looking doctest text) or to put expanded spaces in the doctest output section based on the assumption that output starts in the column under the first of the and that doctest will expand the tabs in the output it receives from the executed test using a tabstop of 8. Neither of these is a good solution (the first gives you messed up looking doctests, the second means the output you document isn't really the output the test gives). The second solution would also mean a significant rewrite of the doctest processing loop. So the best course, since doctests are *primarily* about documentation, is to allow tabs in the output only with whitespace normalization. (If you really want to test for the presence of tabs in the output, as opposed to just creating documentation, you can capture the output and test it using string comparis on.) Personally I think the 'too bad' language in the docs is not really appropriate, so if you can think of a succinct way to document the above, I'll see about getting it in to the docs. -- components: +Documentation -Library (Lib) stage: patch review - needs patch title: doctest should normalize tabs when comparing output - Improve explanation of tab expansion in doctests type: behavior - feature request ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7583 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue6280] calendar.timegm() belongs in time module, next to time.gmtime()
Alexander Belopolsky alexander.belopol...@gmail.com added the comment:
It is too late to get new features in 2.x.
Francesco,
Please double-check timemodule-gmtime-r312.diff, it does not seem to reflect
your reported changes. ('-' vs '--' typo is still there)
There is no need to submit multiple patches. A patch for py3k branch should be
enough.

[issue8540] Make Context._clamp public in decimal module
New submission from Mark Dickinson dicki...@gmail.com: The Context class in the decimal module has a hidden _clamp attribute, that controls whether to clamp values with large exponents. (Clamping a Decimal value involves adding extra significant zeros to decrease its exponent, while not altering the numeric value; it's sometimes necessary to get the exponent within a legal range). I think we should consider making this attribute public (documenting it, having it appear in the __str__ or __repr__ of a Context), for a couple of reasons: (1) It's necessary for full compliance with the specification: Python's default behaviour is actually non-compliant with the spec; it's only after doing getcontext()._clamp = 1 that it complies. (2) Clamping is necessary for modeling the standard formats described in IEEE 754-2008 (decimal64, decimal128), etc. These formats are coming into use in other languages (gcc already supports them and C201x may well include them). To be able to communicate effectively with other languages using these formats, it would be useful to expose Context._clamp. -- components: Library (Lib) messages: 104263 nosy: facundobatista, mark.dickinson, rhettinger, skrah severity: normal stage: unit test needed status: open title: Make Context._clamp public in decimal module type: feature request versions: Python 3.2 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8540 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

If the decision is to deprecate it, deprecation warning need to be added to calendar module and docs updated accordingly.

[issue6280] calendar.timegm() belongs in time module, next to time.gmtime()
Francesco Del Degan f.delde...@ngi.it added the comment: I thinks that isn't a so easy decision to take. And there are some other issues, imho: 1. timegm function is not specified by any standard (POSIX). The portable way (setting TZ, calling mktime, restore TZ) is a pure hack (could not work in future multithreaded environments). 2. if we want to strictly follow the time.h definition from POSIX standards, the timegm function should be kept away from time module (as now). 3. timegm seems to have some issues on mingw32. 4. Solaris doesn't come with the timegm function out-of-the-box. We could give up at this point. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue6280 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
