This is a bug report for perl from [email protected: r...@patsy.ijs.si],
generated with the help of perlbug 1.35 running under perl v5.10.0.
-----------------------------------------------------------------
[Please enter your report here]
With Perl 5.10.0 in taint mode, evaluating a $! variable in
a string context does not yield a system error message text,
but gives a numeric errno code.
The problem is reproducible with an EPIPE error, although
I can not reproduce it with a more trivial I/O error.
The problem is reproducible on all platforms that I tried:
FreeBSD 6.3 in 32-bit mode, FreeBSD 7.0 in 64-bit mode,
and on Linux 2.6.27.9-159.fc10.x86_64.
The following example illustrates the problem.
Standard output is piped into a program which does not read from
its stdin, such as a 'true', intentionally causing a broken pipe:
$ date | /usr/local/bin/perl5.10.0 -T -e '
$|=1; $SIG{PIPE}="IGNORE"; my $s=<STDIN>;
print $s or die "error writing: $!\n"' | true
error writing: 32
The same command with perl 5.8.8 works as expected,
reporting a 'Broken pipe' instead of a '32':
$ date | /usr/local/bin/perl5.8.8 -T -e '
$|=1; $SIG{PIPE}="IGNORE"; my $s=<STDIN>;
print $s or die "error writing: $!\n"' | true
error writing: Broken pipe
Without a -T switch even the perl5.10.0 yields a correct result:
$ date | /usr/local/bin/perl5.10.0 -e '
$|=1; $SIG{PIPE}="IGNORE"; my $s=<STDIN>;
print $s or die "error writing: $!\n"' | true
error writing: Broken pipe
