[issue5949] IMAP4_SSL spin because of SSLSocket.suppress_ragged_eofs
Kevin Watters kevinwatt...@gmail.com added the comment: I wasn't sure--the docs for SSLSocket.read (http://docs.python.org/library/ssl.html#ssl.SSLSocket.read) say Reads up to nbytes bytes from the SSL-encrypted channel and returns them. With that up to I wasn't sure that an empty string would necessarily mean EOF--I'm not familiar enough with _ssl.c to say either way. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue5949 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue5949] IMAP4_SSL spin because of SSLSocket.suppress_ragged_eofs
New submission from Kevin Watters kevinwatt...@gmail.com: I cannot reproduce this locally yet, but I have several bug reports from users showing that IMAP4_SSL connections can get stuck in an infinite loop during logout() File imaplib.pyo, line 529, in logout File imaplib.pyo, line 1059, in _simple_command File imaplib.pyo, line 889, in _command_complete File imaplib.pyo, line 990, in _get_tagged_response File imaplib.pyo, line 907, in _get_response File imaplib.pyo, line 1000, in _get_line File imaplib.pyo, line 1170, in readline File ssl.pyo, line 136, in read IMAP4_SSL uses ssl.wrap_socket and should probably be passing suppress_ragged_eofs=False. Without this, self.sslobj.read() may return '' forever, and both IMAP4_SSL.read() and IMAP4_SSL.readline() will spin. With suppress_ragged_eofs=False, calling logout() may raise an SSLError instead.

[issue4753] Faster opcode dispatch on gcc
Kevin Watters kevinwatt...@gmail.com added the comment: Does anyone know the equivalent ICC command line option for GCC's -fno- gcse? (Or if it has one?) I can't find a related option in the docs. It looks like ICC hits the same combining goto problem, as was mentioned: without changing any options, I applied pitrou_dispatch_2.7.patch to release-26maint and pybench reported literally no difference, +0.0%. Even if stock Python is built with MSVC, devs like myself who ship Python would like to see the benefit. ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4753 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue4379] Py_SAFE_DOWNCAST in FILE_TIME_to_time_t_nsec failing
New submission from Kevin Watters [EMAIL PROTECTED]: After releasing a Py_DEBUG build to some users who were experiencing problems, I noticed a pattern in some of the crash reports I got back: msvcr90d!_wassert+0xb64 python25_d!FILE_TIME_to_time_t_nsec+0xac python25_d!attribute_data_to_stat+0x67 python25_d!win32_wstat+0x6f python25_d!posix_do_stat+0x51 python25_d!posix_stat+0x24 python25_d!PyCFunction_Call+0x65 python25_d!call_function+0x34f python25_d!PyEval_EvalFrameEx+0x4741 The only way I can see _wassert being hit in FILE_TIME_to_time_t_nsec is in the Py_SAFE_DOWNCAST used to downcast an __int64 to int. Py_SAFE_DOWNCAST checks that there is equality between the casted and non-casted values with Py_DEBUG enabled--maybe in this function we should remove Py_SAFE_DOWNCAST? I can't find a way to see the actual value for in before the assert is hit--I'm unfamiliar with picking through minidumps with WinDbg, which for some reason will show me the stack for these dumps when Visual Studio won't. But if I need to investigate more about them I can. -- components: None messages: 76193 nosy: kevinwatters severity: normal status: open title: Py_SAFE_DOWNCAST in FILE_TIME_to_time_t_nsec failing type: behavior versions: Python 2.5.3 ___ Python tracker [EMAIL PROTECTED] http://bugs.python.org/issue4379 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue4260] ctypes.xFUNCTYPE are decorators.
Kevin Watters [EMAIL PROTECTED] added the comment: As far as I know, the above code will fail randomly in release mode if you have multiple threads running Python, because when ctypes calls out to CFUNCTYPE functions, it releases the GIL.

[issue3554] ctypes.wstring_at and string_at call Python API without the GIL
New submission from Kevin Watters [EMAIL PROTECTED]: in Lib/ctypes/__init__.py the wstring_at and string_at functions are declared with CFUNCTYPE. This means that in Modules/_ctypes/callproc.c when the functions are invoked, Py_UNBLOCK_THREADS and Py_BLOCK_THREADS surround the call. But string_at and wstring_at call PyString_FromString and PyUnicode_FromWideChar, respectively. The solution (I think) is to declare the functions with PYFUNCTYPE instead, so that callproc.c doesn't release the GIL when calling them. -- assignee: theller components: ctypes messages: 71135 nosy: kevinwatters, theller severity: normal status: open title: ctypes.wstring_at and string_at call Python API without the GIL type: crash versions: Python 2.5, Python 2.6, Python 2.7, Python 3.0, Python 3.1 ___ Python tracker [EMAIL PROTECTED] http://bugs.python.org/issue3554 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue3006] subprocess.Popen causes socket to remain open after close
Kevin Watters [EMAIL PROTECTED] added the comment: I found a workaround for this issue (attached) via the kernel32.dll function SetHandleInformation. You can patch the socket class to set all newly created sockets as uninheritable. It's not perfect--another thread could still spawn a subprocess in between. We probably need some kind of API for setting socket inheritance.
