Perl::Critic::Policy::BuiltinFunctions::ProhibitSleepViaSelect - Use Time::HiRes instead of something like select(undef, undef, undef, .05)
.
This Policy is part of the core Perl::Critic distribution.
Conway discourages the use of select()
for performing non-integer
sleeps. Although documented in perlfunc, it's something
that generally requires the reader to read perldoc -f select
to
figure out what it should be doing. Instead, Conway recommends that
you use the Time::HiRes
module when you want to sleep.
select undef, undef, undef, 0.25; # not ok
use Time::HiRes; sleep( 0.25 ); # ok
This Policy is not configurable except for the standard options.
