[issue19809] Python get stuck in second Popen call
STINNER Victor added the comment: The creation of slave_popen is not protected by a lock, and so dummy_thread() may spawn a new process (master) at the same time than the main process (slave). If it occurs at the same time, the master may inherit a pipe of the slave process used internally by the subprocess module to send the exception to the parent process if a Python exception occurs in the child process. The inheritance of pipes has been partially fixed in Python 3.2 with the new function _posixsubprocess.cloexec_pipe() which uses pipe2() function to atomically create a pipe with the O_CLOEXEC flag set. The problem has been fixed complelty in Python 3.4 with the PEP 446: all files are now created non inheritable by default, and atomic functions to set the non inheritable flag are used when available. You posted a Python 2.7 script, so I suppose that you are stuck at Python 2. In this case, you can workaround the issue by using a lock around the creation of any subprocess. To fix your example, just surround slave_popen creation with with lock: ... or lock.acquire()/lock.release(), as you did for master_popen. I propose to convert this issue to a documentation issue: we should add a warning explaining that spawning processes in more than one thread can lead to such race condition and hang one or more threads. And suggest to use a lock to workaround such issue. See also the atfork proposition which includes such lock: http://bugs.python.org/issue16500 -- Your script has other issues: - you should pass a file open in write mode for stdout/stderr - you should close open(os.devnull) files, or open them outside the loop - you should join the thread, or use a daemon thread. If you don't join threads, you will quickly read the limit of the number of threads - you can use shell=True to avoid spawning two process to run sleep (or simply use time.sleep :-)) - you need a synchronization between the two threads to ensure that master_popen is created before trying to kill it -- nosy: +haypo, neologix, sbt ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19809 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

STINNER Victor added the comment: You can retrieve the module using sys.modules[symbol.__module__]. Example: from os import environ as ENV import imp, sys imp.reload(sys.modules[ENV.__module__]) module 'os' from '/usr/lib64/python2.7/os.pyc' _.environ is ENV False But if you import symbols instead of modules, symbols will still point to the old version of the module. This explain the final False result. You should import modules if you want to play with reload(). I prefer to exit and restart Python instead of playing with reload, I see it as a hack which has many issues like _.environ is ENV returning False. -- nosy: +haypo ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19812 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue19813] Add a new optional timeout parameter to socket.socket() constructor
New submission from STINNER Victor: Since Linux 2.6.28, socket() syscall accepts a new SOCK_NONBLOCK flag in the socket type. It avoids 1 or 2 extra syscalls to set the socket in non-blocking mode. This flag comes also slowly in other operating systems: NetBSD, FreeBSD, etc. FreeBSD: http://lists.freebsd.org/pipermail/freebsd-hackers/2013-March/042242.html Discussion in the POSIX standard: http://austingroupbugs.net/view.php?id=411 Avoiding the syscalls has been proposed on python-dev a few months ago: https://mail.python.org/pipermail/python-dev/2013-January/123661.html I tried to include SOCK_NONBLOCK in my PEP 446, but I have been asked to treat it separatly because it's completly different than O_CLOEXEC (even it looks similar). http://hg.python.org/peps/file/fa873d5aed27/pep-0446.txt#l64 I also proposed to add 2 functions in the PEP: * ``os.get_blocking(fd:int) - bool`` * ``os.set_blocking(fd:int, blocking: bool)`` I propose to add a new timeout parameter to socket.socket() constructor which would set the timeout internal attribute and set O_NONBLOCK flag using the new SOCK_NONBLOCK flag, ioctl() or fcntl() (depending on the OS and on what is available). I don't know if something special should be done on Windows for non-blocking sockets? socket.socket.setblocking() already exists and I suppose that it works on Windows :-) See also the discussion in my old PEP for non-blocking operations in files on Windows: http://hg.python.org/peps/file/fa873d5aed27/pep-0446.txt#l177 I don't know if the new parameter can just be added at the end of the parameter list, or it should be a keyword-only parameter to avoid breakpoint backward compatibility? socket.socketpair() and socket.socket.dup() and socket.fromfd(), socket.create_connection() (and more generally any function creating a new socket) may also be modified. -- By the way, internal_setblocking() currently uses 2 fcntl() syscalls on Linux, whereas it could be implemented with a single ioctl() syscall using FIONBIO. Set O_NONBLOCK flag: int flag = 1; ioctl(fd, FIONBIO, flag); Clear O_NONBLOCK flag: int flag = 0; ioctl(fd, FIONBIO, flag); Tell me if you prefer a different issue for this optimization. -- messages: 204575 nosy: gvanrossum, haypo, pitrou priority: normal severity: normal status: open title: Add a new optional timeout parameter to socket.socket() constructor type: enhancement versions: Python 3.5 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19813 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Brian Curtin added the comment: If a platform does not actually support symlinks, and XP does not actually support symlinks for any usual definition of an operating system supporting a feature, then I'm not sure why pathlib is doing something wrong to make it work more reasonably in that case. os.symlink is a NotImplementedError on Windows versions prior to Vista because the Windows API doesn't support CreateSymbolicLink.

[issue19792] pathlib does not support symlink in Windows XP
Antoine Pitrou added the comment: The 2.7-compatible version of pathlib explains why the code is structured this way: if sys.getwindowsversion()[:2] = (6, 0) and sys.version_info = (3, 2): from nt import _getfinalpathname else: supports_symlinks = False _getfinalpathname = None In the stdlib version, I removed the `sys.version_info = (3, 2)` and so it may look like as easy to rely on os.symlink raising NotImplementedError.

[issue19817] tracemalloc add a memory limit feature
New submission from STINNER Victor: It would be nice to add a memory_limit feature to the tracemalloc to make memory allocation fails if it would make the traced memory greater than the limit. See also the pyfailmalloc project which is similar but different: https://bitbucket.org/haypo/pyfailmalloc pyfailmalloc doesn't count allocated bytes, it schedules an error in N allocations where N is a random number. And pyfailmalloc only schedules one error, whereas I propose to make all memory allocations fails until the limit is respected. So if you only 0 bytes free (according to the limit), all memory allocations fail until some bytes are freed. Python currently behaves badly under very low memory condition. See also the issue #19437. -- files: tracemalloc_memory_limit.patch keywords: patch messages: 204605 nosy: haypo, neologix priority: normal severity: normal status: open title: tracemalloc add a memory limit feature versions: Python 3.5 Added file: http://bugs.python.org/file32873/tracemalloc_memory_limit.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19817 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue19819] reversing a Unicode ligature doesn't work
New submission from Larry Hastings: Read this today: http://mortoray.com/2013/11/27/the-string-type-is-broken/ In it the author talks about how the 'ffl' ligature breaks some string processing. He claimed that Python 3 doesn't uppercase it correctly--well, it does. However I discovered that it doesn't reverse it properly. x = b'ba\xef\xac\x84e'.decode('utf-8') # baffle, where ffl is a ligature print(x) # prints baffle, with the ligature print(x.upper()) # prints BAFFLE, no ligature, which is fine print(.join(reversed(x))) # prints efflab Shouldn't that last line print elffab? If this gets marked as wontfix I wouldn't complain.

[issue19819] reversing a Unicode ligature doesn't work
Christian Heimes added the comment: There is no ligature for lff, just ffl. Ligatures are treated as one char. I guess Python would have to grow a str.reverse() method to handle ligatures and combining chars correctly. At work I ran into the issue with ligatures and combining chars multiple times in medieval and early modern age scripts. Eventually I started to normalize all incoming data to NFKC. That solves most of the issues. s = b'ba\xef\xac\x84e'.decode('utf-8') print(.join(reversed(s))) efflab print(.join(reversed(unicodedata.normalize(NFKC, s elffab -- nosy: +christian.heimes ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19819 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue19819] reversing a Unicode ligature doesn't work
Christian Heimes added the comment: A proper str.reverse function must deal with more extra cases. For example there are special rules for the Old German long s (ſ) and the round s (s). A round s may only occur at the end of a syllable. Hebrew has a special variant of several characters if the character is placed at the end of a word (HEBREW LETTER PE / HEBREW LETTER FINAL PE).

[issue19787] tracemalloc: set_reentrant() should not have to call PyThread_delete_key()
STINNER Victor added the comment: I ran test_tracemalloc on Linux and Windows and the test passed successfully. It should probably be better to split the patch in two parts if the idea of changing Python/thread* files is accepted. (But initially, the issue comes from the tracemalloc module.) set_reentrant() of tracemalloc.c: +assert(PyThread_get_key_value(tracemalloc_reentrant_key) == REENTRANT); I also added a new assertion to ensure that set_reentrant(0) was not called twice. It was a suggesed of Jim Jewett. This is unrelated to this issue and should be commited separatly. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19787 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue19764] subprocess: use PROC_THREAD_ATTRIBUTE_HANDLE_LIST with STARTUPINFOEX on Windows Vista
STINNER Victor added the comment: The purpose of this issue is to avoiding having to call CreateProcess() with bInheritHandles parameter set to TRUE on Windows, and avoid calls to self._make_inheritable() in subprocess.Popen._get_handles(). Currently, bInheritHandles is set to TRUE if stdin, stdout and/or stderr parameter of Popen constructor is set (to something else than None). Using PROC_THREAD_ATTRIBUTE_HANDLE_LIST, handles don't need to be marked as inheritable in the parent process, and CreateProcess() can be called with bInheritHandles parameter set to FALSE. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19764 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue19764] subprocess: use PROC_THREAD_ATTRIBUTE_HANDLE_LIST with STARTUPINFOEX on Windows Vista
STINNER Victor added the comment: UpdateProcThreadAttribute() documentation says that ... handles must be created as inheritable handles ... and a comment says that If using PROC_THREAD_ATTRIBUTE_HANDLE_LIST, pass TRUE to bInherit in CreateProcess. Otherwise, you will get an ERROR_INVALID_PARAMETER. http://msdn.microsoft.com/en-us/library/windows/desktop/ms686880%28v=vs.85%29.aspx Seriously? What is the purpose of PROC_THREAD_ATTRIBUTE_HANDLE_LIST if it does not avoid the race condition? It's just to not inherit some inheritable handles? In Python 3.4, files and sockets are created non-inheritable by default, so PROC_THREAD_ATTRIBUTE_HANDLE_LIST may not improve anything :-/ -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19764 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
