Python Error In Sys.exitfunc
sys.ps1¶ sys.ps2¶ Strings specifying the primary and secondary prompt of the interpreter. They are saved so that displayhook and excepthook can be restored in case they happen to get replaced with broken objects. Note that as an exception is propagated down the chain of callers, an 'exception' event is generated at each level. They are used during finalization, and could be useful to print to the actual standard stream no matter if the sys.std* object has been redirected. this contact form
Any optional arguments that are to be passed to func must be passed as arguments to register(). New in version 2.5. Note: This module is unlikely to work correctly when used with other code that sets sys.exitfunc. This function should be used for internal and specialized purposes only. http://stackoverflow.com/questions/80993/how-to-skip-sys-exitfunc-when-unhandled-exceptions-occur
For example, to test that the Python interpreter is at least version 1.5.2, use: if sys.hexversion >= 0x010502F0: # use some advanced feature ...

New in version 2.5. New in version 2.0. If name does not match any available encoding, LookupError is raised. After all exit handlers have had a chance to run the last exception to be raised is re-raised.

sys.getdlopenflags()¶ Return the current value of the flags that are used for dlopen() calls. my review here This is the usual behaviour in Python 2.7 and later. For other systems, the values are: System platform value Linux (2.x and 3.x) 'linux2' Windows 'win32' Windows/Cygwin 'cygwin' Mac OS X 'darwin' OS/2 'os2' OS/2 New in version 2.3.
The trace function is invoked (with event set to 'call') whenever a new local scope is entered; it should return a reference to a local trace function to be used weblink You signed out in another tab or window. It's True when Python is started with the -3 option. (This should be considered read-only; setting it to a different value doesn't have an effect on Python 3 warnings.) New See also Module readline Useful example of atexit to read and write readline history files. 28.9.1. atexit Example¶ The following simple example demonstrates how a module can
- The parent starts the child, pauses, then kills it: import os import signal import subprocess import time proc = subprocess.Popen('atexit_signal_child.py') print 'PARENT: Pausing before sending signal...' time.sleep(1) print 'PARENT: Signaling child'
- import atexit import os def not_called(): print 'This should not be called' print 'Registering' atexit.register(not_called) print 'Registered' print 'Exiting...' os._exit(0) Since we call os._exit() instead of exiting normally, the callback is
- import atexit def exit_with_exception(message): raise RuntimeError(message) atexit.register(exit_with_exception, 'Registered first') atexit.register(exit_with_exception, 'Registered second') Notice again that the registration order controls the execution order.
- In particular, sys.exit("some error message") is a quick way to exit a program when an error occurs.
Note to self: try seeing what happens if one calls grpc_shutdown before calling some other grpc_*_destroy function. The ceph-deploy codebase does not use atexit, but execnet does, which we bundle. Otherwise, the values returned are (type, value, traceback). navigate here asked 8 years ago viewed 1824 times active 1 year ago Blog Stack Overflow Podcast #92 - The Guerilla Guide to Interviewing Related 1274Catch multiple exceptions at once?1007How do you assert
sys.getfilesystemencoding()¶ Return the name of the encoding used to convert Unicode filenames into system file names, or None if the system default encoding is used. sys.getsizeof(object[, default])¶ Return the size of an object in bytes. The type cache is used to speed up attribute and method lookups.
This function will be called when the interpreter exits.
If you do need the traceback, make sure to delete it after use (best done with a try ... finally statement) or to call exc_info() in a function Page Contents atexit - Call functions when a program is closing down Examples When are atexit functions not called? New in version 2.6. sys.excepthook(type, value, traceback)¶ This function prints out a given traceback and exception to sys.stderr.
If the current stack frame is not handling an exception, the information is taken from the calling stack frame, or its caller, and so on until a stack frame is found kpayson64 commented Jun 14, 2016 @nathanielmanistaatgoogle The primary issue here should already be resolved. #6873 solves the general problem of stub shutdown in the event of an outstanding call, which doesn't
