| Summary : kill your broken Perl script
|
Description :
It is oh so very easy to accidentally write a Perl script that dives
straight into an infinite loop, or stumbles into a runaway recursion. In
most cases, you can hit \'Ctrl + C\' and get on with the job of figuring out
what went wrong. However, if you\'re not running the process in a local
terminal (e.g. you\'re running it over a slow SSH connection, or not in a
terminal at all), these processes might be tricky to kill.
The Time::Limit module starts a monitor process that shadows your script\'s
execution, and kills it off if your script has overrun its allotted time
limit. Because Time::Limit is global in effect its use in modules is
discouraged. Instead, use it only in your main script, or pass it as a
parameter to Perl on the command line:
perl -MTime::Limit myscript.pl
The syntax for using Time::Limit is:
use Time::Limit AATTflags, $limit;
Flags are strings prefixed with a hyphen. The following flags are
supported:
* \'-group\'
Send the signal to your script\'s process group instead of its individual
process number. That is, your script and any child processes started with
\'fork\' will be killed.
* \'-quiet\'
Kill the script quietly.
* \'-verbose\'
Output extra debugging information.
The \'$limit\' is a number indicating the time in seconds before your script
gets killed. It does not have to be an integer. It defaults to a very
generous 10.
Be careful to avoid triggering Perl\'s \'use MODULE VERSION\' syntax.
use Time::Limit -verbose, 4.0; # yep, kill after 4 seconds
use Time::Limit \'4.0\'; # yep, kill after 4 seconds
use Time::Limit 4.0; # nah, want $VERSION==4.0
After \'$limit\' is reached, Time::Limit will try signalling your script to
terminate cleanly (SIGTERM) a few times; if that fails, it will become more
aggressive and send SIGKILL signals until it receives word of your script\'s
timely death.
Some random examples using Time::Limit from the command-line:
perl -MTime::Limit=-quiet,4 myscript.pl
perl -MTime::Limit=-group,-verbose,4.1 myscript.pl
perl -MTime::Limit=3 myscript.pl
