Python Error In Sys.excepthook

Thanks for sharing.. arg is the C function object. 'c_exception' A C function has raised an exception. New in version 2.3. The local trace function is called; arg is the value that will be returned, or None if the event is caused by an exception being raised. http://caribtechsxm.com/python-error/python-error-log-mac.php

Python 2.7.8 on Ubuntu 14.04 –Aaron McDaid Feb 2 at 12:43 1 The -u option to python (unbuffered output) seems relevant too. This limit prevents infinite recursion from causing an overflow of the C stack and crashing Python. If the tree was exported (or svnversion was not available), it is the revision of Include/patchlevel.h if the branch is a tag. A user may need to set the limit higher when she has a program that requires deep recursion and a platform that supports a higher limit. http://stackoverflow.com/questions/12790328/how-to-silence-sys-excepthook-is-missing-error

This is called hexversion since it only really looks meaningful when viewed as the result of passing it to the built-in hex() function. Using exc_info() is preferred over the old form (with exc_type, exc_value, and exc_traceback) because it is thread-safe.

  1. See Objects/lnotab_notes.txt for a detailed explanation of how this works. 'return' A function (or other code block) is about to return.
  2. The Pallets Projects member untitaker commented Sep 5, 2013 Can you confirm this patch works?
  3. Yes you can remove the code that calls join and the Python environment will wait for all threads to complete before terminating execution.

This is guaranteed to increase with each version, including proper support for non-production releases. http://stackoverflow.com/questions/9532264/how-to-use-multiple-threads Since most functions don't need access to the traceback, the best solution is to use something like exctype, value = sys.exc_info()[:2] to extract only the exception type

if (hook && hook != Py_None) { ... } else { PySys_WriteStderr("sys.excepthook is missing\n"); PyErr_Display(exception, v, tb); } After notifying us about the missing excepthook, Python then falls back to printing PyObject *f = PySys_GetObject("stderr"); In this case, that doesn't work because sys.stderr has already been cleared and is inaccessible.3 So the code invokes fprintf directly to send the third message to What is/will be the recommended solution for people who want their programs to finish totally but not complain when their pipe is cut off in Python 3? You'll just see the message from the exception.

Or for a simpler example, consider a script printer.py containing nothing more than print 'abcde' Then python printer.py | python printer.py will produce the same error.

Its behavior is part of the implementation platform, rather than part of the language definition, and thus may not be available in all Python implementations. sys.settscdump(on_flag)¶ Activate dumping of VM news The thread module is not what you need. EDIT: The following script, which differs from the original one above only in that it redefines sys.excepthook, behaves exactly like the one given above.

Also, its return value is not used, so it can simply return None. sys.path_hooks¶ A list of callables that take a path argument to try to create a finder for the path.

Jun 10 '14 at 3:50 @MarkZ. The attributes are read only. As long as the buffer is nonempty, any attempt to close the writing file object is supposed to fail with an error. Do not extract version information out of it, rather, use version_info and the functions provided by the platform module.
