[issue44377] Truncated error message of original function while multiprocessing or multithreading
New submission from Prasanth Rajendran : Under multiprocessing package, in pool.py, when an error occurs on line 122: result = (True, func(*args, **kwds)) The exception "e" has the error message due to execution of the function that is executed in parallel. However, the error message is lost when another error is occurred due to the execution of following line 128: put((job, i, result)) The MaybeEncodingError masks or truncates the original error message, due to the following line at 130: MaybeEncodingError(e, result[1]) where the repr function in the class truncates the message. The final error message has pickling error and the masked error of the actual execution. -- components: Library (Lib) messages: 395529 nosy: mrshanth priority: normal severity: normal status: open title: Truncated error message of original function while multiprocessing or multithreading versions: Python 3.7 ___ Python tracker <https://bugs.python.org/issue44377> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

New submission from shiva prasanth: i created a zip file with password as getlost using Archive Manager which comes with ubuntu. and when i try to extract the same file using zipfile module which comes with python2.7 with same password it is showing error as Bad Password for file which is absurd. it should either give response of cant decrypt zipfile or some other. when i try to do it with terminal command $zip --encrypt file.zip file and upon entering the password it is working my main point is it should not show Bad Password for file and and it should extractall -- components: Extension Modules files: raj messages: 248698 nosy: shiva prasanth priority: normal severity: normal status: open title: Bad Password for file using zipfile module versions: Python 2.7 Added file: http://bugs.python.org/file40192/raj ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24877 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

But the above program is giving the output as : If we print pingresult it is giving the output as : ['\r\n', 'Pinging 0.168.1.1 with 32 bytes of data:\r\n', '\r\n', 'Request timed out.\r\n', '\r\n', 'Ping statistics for 0.168.1.1:\r \n', 'Packets: Sent = 1, Received = 0, Lost = 1 (100% loss),\r\n'] my requirement is IP address and whether the machine is pinging or not. we should not display the above output. However we can do it by using regular expression or there is any other way. Please suggest. Thanks, Prasanth. -- http://mail.python.org/mailman/listinfo/python-list
