NAME Timeout::Self - Run alarm() at the start of program to timeout run VERSION This document describes version 0.020 of Timeout::Self (from Perl distribution Timeout-Self), released on 2020-07-10. SYNOPSIS In a script: # run for at most 30 seconds use Timeout::Self 30; # do stuffs From the command line: % perl -MTimeout::Self=30 yourscript.pl DESCRIPTION This module lets you set a time limit on program execution, by installing a handler in $SIG{ALRM} that simply dies, and then calling "alarm()" with the specified number of seconds. Caveat: it doesn't play perfectly nice with programs that fork. While the alarm handler gets cloned to the child process by Perl, the alarm is not set again so the child process will not time out. You can call alarm() again in the child process if you want to timeout the child too. HOMEPAGE Please visit the project's homepage at . SOURCE Source repository is at . BUGS Please report any bugs or feature requests on the bugtracker website When submitting a bug or request, please include a test-file or a patch to an existing test-file that illustrates the bug or desired feature. SEE ALSO Sys::RunUntil can timeout your script by number of clock seconds or CPU seconds. It performs "fork()" at the beginning of program run. Timing out a process can also be done by a supervisor process, for example see Proc::Govern, IPC::Run (see "timeout()").
