Interrupting Cow

MOOOOO!

Overview

Interruptingcow is a generic utility can relatively gracefully interrupt your Python code when it doesn't execute within a specific number of seconds:

from interruptingcow import timeout

try:
    with timeout(5):
        # perform a potentially very slow operation
        pass
except RuntimeError:
    print "didn't finish within 5 seconds"

Installation

$ pip install interruptingcow

Caveats

Interruptingcow uses signal(SIGALRM) to let the operating system interrupt program execution. This has the following limitations:

  1. Python signal handlers only apply to the main thread, so you cannot use this from other threads
  2. You must not use this in a program that uses SIGALRM itself
Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
