Broken Pipe Python Error


All of these can be overridden. The only issue still left here is how to catch that exception within the script itself; that would be nice so (for example) the script could have time to flush out Thanks! –mathtick Nov 5 '10 at 14:47 add a comment| up vote 0 down vote try using communicate(), rather than reading directly from stdout.

Of course, if you used Twisted rather than spawning a new thread for each client connection, you probably wouldn't have this problem.

It may be that the pipe breaks after a period of inactivity, and subsequent activity shows up the break. By default - i.e., if the writing process does not explicitly trap SIGINT - the writing process is simply terminated, and its exit code is set to 141, which is calculated msg237124 - (view) Author: STINNER Victor (haypo) * Date: 2015-03-03 12:01 I would be safer to use a bufsize a little bit larger :-) proc = subprocess.Popen([...], bufsize=support.PIPE_MAX_SIZE * 2, stdin=subprocess.PIPE, Werkzeug Broken Pipe This takes seconds in the shell.

Since your email I have reviewed your documentation and now see the raiseExceptions variable. For example, if your sendall always completes immediately (or very quickly) on the personal computer, the connection may simply never have broken during sending. You don't want to mask bugs like division by zero or out of memory. –S.Lott Oct 7 '08 at 20:46 1 If you are using Python's socket module, you will check over here Thanks for subscribing!

Actually the problem is not that Python catches SIGPIPE, but rather that it ignores it - as in, signal(SIGPIPE, SIG_IGN) Then the write returns an error 32 EPIPE, which naturally turns except python - How to prevent errno 32 broken pipe? - Stack Overflow View More at http://stackoverflow.com/questions/11866792/how-to-prevent-errno-...

You can reduce the incidence (but not entirely eliminate) of this by using select.select() (or poll). In your case a python seems to throw an exception that can be handled as a premature disconnect of the client. You have 2 votes for a (still) bad answer. You can also just apply the band-aid of catching the exception in some top-level handler in each thread.

I've changed my code to consume the entire input and the error went away. I presume that I simply use logging.raiseExceptions = False after import logging I used signal.SIGPIPE after googling for Broken Pipe. And for the VMWare Workstation, I am using Host-only option for network connection.
