[issue3862] test_array fails on FreeBSD7 amd64
Mark Dickinson [EMAIL PROTECTED] added the comment:
Thanks, Alan. I realised my answer was a shallow one after reading (too
late!) the thread you started on python-dev.
However, I have a suspicion that that particular array test
(test_alloc_overflow) was merely meant to test the code in
newarrayobject, at around line 427 of arraymodule.c, which looks like:
/* Check for overflow */
if (nbytes / descr-itemsize != (size_t)size) {
return PyErr_NoMemory();
}
and that the test dated from an era when it was fairly safe to assume
that a size_t was at most 32 bits. I'd guess that test_alloc_overflow
was never intended to be a test of OS malloc failure behaviour.
So the array test is wrong, and I think this patch should be applied
anyway. I admit this doesn't help with the much more interesting
question of what's going on with malloc on FreeBSD.

[issue3900] ctypes: wrong calling convention for _string_at
New submission from STINNER Victor [EMAIL PROTECTED]: Our application server running on top of Twisted crashs 1 to 3 times per day. It uses a ctypes binding for libnetfilter_conntrack (dump Linux conntrack table) which is running in a dedicated thread. So we get: - Python 2.5.2 - Twisted 8.1.0-3 - Linux 2.6.26-1-amd64 SMP x86_64 The crash does not occur in the ctypes thread but it the main thread (another CPython thread). The backtrace is incoherent which means that it's a multithreading problem. So I used helgrind (Valgrind tool) to watch invalid memory accesses, and here is one: ==30545== Possible data race during write of size 4 at 0x4EC1E60 ==30545==at 0x808F616: PyString_FromStringAndSize (stringobject.c:78) ==30545==by 0x4D3CBD9: string_at (_ctypes.c:4568) ==30545==by 0x4D4654E: ffi_call_SYSV (sysv.S:60) ==30545==by 0x4D46396: ffi_call (ffi.c:221) ==30545==by 0x4D3E9F1: _call_function_pointer (callproc.c:668) ==30545==by 0x4D3F147: _CallProc (callproc.c:991) ==30545==by 0x4D3B0DA: CFuncPtr_call (_ctypes.c:3373) ==30545==by 0x8060E0A: PyObject_Call (abstract.c:1861) ==30545==by 0x80CB391: do_call (ceval.c:3784) ==30545==by 0x80CAD69: call_function (ceval.c:3596) ==30545==by 0x80C7B6F: PyEval_EvalFrameEx (ceval.c:2272) ==30545==by 0x80C9329: PyEval_EvalCodeEx (ceval.c:2836) ==30545== Old state: shared-readonly by threads #1, #4 ==30545== New state: shared-modified by threads #1, #4 ==30545== Reason:this thread, #1, holds no consistent locks ==30545== Location 0x4EC1E60 has never been protected by any lock In _CallProc() the test ((flags FUNCFLAG_PYTHONAPI) == 0) is True, which means that the GIL is released. But it's a bug because as you can see, string_at() uses PyString_FromStringAndSize() which requires the GIL! Finally, the bug comes from ctypes module, not _ctypes: ctypes just uses the wrong calling convention. Using PYFUNCPTR() instead of CFUNCPTR(), the Helgrind warning goes away ;-) Note about Helgrind: This tools really rocks!!! -- components: Library (Lib) files: ctypes_string_at.patch keywords: patch messages: 73385 nosy: haypo severity: normal status: open title: ctypes: wrong calling convention for _string_at versions: Python 2.5, Python 2.6, Python 3.0 Added file: http://bugs.python.org/file11520/ctypes_string_at.patch ___ Python tracker [EMAIL PROTECTED] http://bugs.python.org/issue3900 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue3885] errors on _bsddb creation and dealloc
Jesús Cea Avión [EMAIL PROTECTED] added the comment:
Not only in these functions, but anywhere dummy= is followed by a
Py_XDECREF(dummy);
Please, clarify this. I don't see your point.
And code like this must also be changed (in DB_open):
if (makeDBError(err)) {
PyObject *dummy;
dummy=DB_close_internal(self,0);
Py_XDECREF(dummy);
return NULL;
}
if DB_close_internal() raises an exception it will replace the
original error set by makeDBError(). I'm not sure this is desirable.
I agree this could be an issue that need to be studied. Please, post a
new bug report for that (to be addressed in 2.6.1, I think, since this
issue doesn't crash the interpreter).
I post a patch for the bugs originally indicated in this bug report, an
another one (db.verify() regression).
*Please Review*. I will update python 2.6 svn when the review is done.
Thanks.

If dummy is NULL, a pending exception has been set (with PyErr_SetString or another similar function). If you simply ignore this, your function will return a valid object, but PyErr_Occurred() returns True. This is not correct and will fail in subtle ways (like with gc.collect()); in debug mode, a message XXX undetected error is printed.

However, distutils does not create an __init__.py file in that directory, so it is not actually a package and is not importable. -- components: Distutils messages: 73393 nosy: Peaker severity: normal status: open title: distutils does not correctly create packages for compiled extensions type: behavior versions: Python 2.5 ___ Python tracker [EMAIL PROTECTED] http://bugs.python.org/issue3902 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue3904] asynchat async_chat __init__() arguments changed in python 2.6
New submission from Forest Wilkinson [EMAIL PROTECTED]: In python 2.6rc2, the async_chat.__init__() parameters have changed. The first arg was called 'conn' in python 2.5, and it is now called 'sock'. This change breaks code that worked with previous python 2.x versions, if that code followed the example in the official docs: class http_request_handler(asynchat.async_chat): def __init__(self, conn, addr, sessions, log): asynchat.async_chat.__init__(self, conn=conn) The change also breaks the 2.6 docs, as they have not been updated to reflect the newly renamed parameter. http://docs.python.org/dev/library/asynchat.html#id1 The change appears to come from Nadeem Vawda as part of issue1519. (See msg57989.) I expect that existing python code could be modified to work around the problem by using positional args instead of keyword args. However, I didn't expect to have to update my working code to accommodate such a change in the python 2.x code line. I agree that 'sock' is a better name for the parameter, especially since it matches the same in asyncore.dispatcher, but should the change really happen before python 3.0? If so, let's at least update the docs. -- components: Library (Lib) messages: 73405 nosy: forest, nvawda severity: normal status: open title: asynchat async_chat __init__() arguments changed in python 2.6 versions: Python 2.6 ___ Python tracker [EMAIL PROTECTED] http://bugs.python.org/issue3904 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue1641] asyncore delayed calls feature
Josiah Carlson [EMAIL PROTECTED] added the comment: I have an updated sched.py module which significantly improves the performance of the cancel() operation on scheduled events (amortized O(log(n)), as opposed to O(n) as it is currently). This is sufficient to make sched.py into the equivalent of a pair heap. From there, it's all a matter of desired API and features. My opinion on the matter: it would be very nice to have the asyncore loop handle all of the scheduled events internally. However, being able to schedule and reschedule events is a generally useful feature, and inserting the complete functionality into asyncore would unnecessarily hide the feature and make it less likely to be used by the Python community. In asyncore, I believe that it would be sufficient to offer the ability to call a function within asyncore.loop() before the asyncore.poll() call, whose result (if it is a number greater than zero, but less than the normal timeout) is the timeout passed to asyncore.poll(). Obviously the function scheduler would be written with this asyncore API in mind. ___ Python tracker [EMAIL PROTECTED] http://bugs.python.org/issue1641 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue3907] for line in file doesn't work for pipes
New submission from endolith [EMAIL PROTECTED]: One of the principles of Python is that There should be one-- and preferably only one --obvious way to do it. It seems that the for line in file idiom is The Way to iterate over the lines of a file, and older more explicit methods are deprecated. PEP 234 says that this: for line in file: ... is equivalent to this: for line in iter(file.readline, ): ... or this: while 1: line = file.readline() if not line: break ... However, for line in file does not behave the same as the other two if the file is a named pipe. This is presumably due to the hidden read-ahead buffer in the low-level implementation of the next() method of the file iterator (http://docs.python.org/lib/bltin-file-objects.html), meant to increase the speed at which it reads regular physical files. Since not enough data exists in the pipe to fill the buffer yet, the lines are only read in a burst after the buffer has been filled or when the pipe is closed. My application is monitoring a pipe for new lines from a logging program, and I want each line read as soon as it is written. Sure, there are other ways to get this functionality, but I don't see why for line in file shouldn't behave the same way for any file-like object. I wonder if it can be made to internally use the read-ahead buffer for closed physical files, and a different method for open named pipes. I wonder if reading pipes character-by-character causes any significant slowdown compared to the read-ahead buffer when the pipe resides in memory instead of a disk. Forgive me if this is not really a bug, but it seems to my beginner eyes that things are not working the way they should. http://python-forum.org/pythonforum/viewtopic.php?t=9300 http://ubuntuforums.org/showthread.php?t=916518 -- components: Interpreter Core messages: 73419 nosy: endolith severity: normal status: open title: for line in file doesn't work for pipes type: behavior versions: Python 2.5 ___ Python tracker [EMAIL PROTECTED] http://bugs.python.org/issue3907 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue3905] subprocess failing in GUI applications on Windows
Trent Mick [EMAIL PROTECTED] added the comment: The failure is in the DuplicateHandle call that subprocess makes on, in this case, the stdin handle (as returned by `GetStdHandle(STD_INPUT_HANDLE)`) call earlier. Two cases here: 1. When this is run in a subsystem:windows process (like PythonWin or IDLE) that is launched from Windows Explorer (e.g. from a Start Menu shortcut or Desktop shortcut) then `GetStdHandle(STD_INPUT_HANDLE)` returns None. [http://msdn.microsoft.com/en-us/library/ms683231(VS.85).aspx] If an application does not have associated standard handles, such as a service running on an interactive desktop, and has not redirected them, the return value is NULL. In this case you *don't* get the error that Todd described, because the code path taken in subprocess.py then use CreatePipe for the `p2cread` variable on which `DuplicateHandle` is called. 2. However, when the subsystem:windows process is launched from the cmd.exe shell the `GetStdHandle` call returns a value -- in Todd's and my testing, the value 3. The code path in subprocess.py then calls `DuplicateHandle` on this in `Popen._make_inheritable`. This fails with traceback Todd posted. My *guess* at what the problem is stems from this comment in the MSDN docs on console handles: [http://msdn.microsoft.com/en-us/library/ms682075(VS.85).aspx] A process can use the DuplicateHandle function to create a duplicate console handle that has different access or inheritability from the original handle. Note, however, that a process can create a duplicate console handle only for its own use. This differs from other handle types (such as file, pipe, or mutex objects), for which DuplicateHandle can create a duplicate that is valid for a different process. My guess is that the stdin handle (3) is inherited from the shell (cmd.exe) and attempting to `DuplicateHandle` on it violates the clause that you can on dupe a console handle of your own. I'm not sure of that though. Anyone else have more light to shed on this? If this is the case I'm not sure what a possible or good solution could be for subprocess. ___ Python tracker [EMAIL PROTECTED] http://bugs.python.org/issue3905 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
