In Perl 5.8.0 the so-called "safe signals" were introduced. This means that Perl
|
|
no longer handles signals immediately but instead "between opcodes", when it is
|
|
safe to do so. The earlier immediate handling easily could corrupt the internal
|
|
state of Perl, resulting in mysterious crashes.
|
|
|
|
It's possible since perl 5.8.1 to globally disable this feature by using the
|
|
PERL_SIGNALS environment variables (as specified in "PERL_SIGNALS" in perlrun);
|
|
but there's no way to disable it locally, for a short period of time. That's
|
|
however something you might want to do, if, for example, your Perl program calls
|
|
a C routine that will potentially run for a long time and for which you want to
|
|
set a timeout.
|
|
|
|
This module therefore allows you to define UNSAFE_SIGNALS blocks in which
|
|
signals will be handled "unsafely".
