NAME
README.freebsd - Perl version 5 on FreeBSD systems
DESCRIPTION
This document describes various features of FreeBSD that will affect how Perl ver-
sion 5 (hereafter just Perl) is compiled and/or runs.
FreeBSD core dumps from readdir_r with ithreads
When perl is configured to use ithreads, it will use re-entrant library calls in
preference to non-re-entrant versions. There is a bug in FreeBSD's "readdir_r"
function in versions 4.5 and earlier that can cause a SEGV when reading large
directories. A patch for FreeBSD libc is available (see
http://www.freebsd.org/cgi/query-pr.cgi?pr=misc/30631 ) which has been integrated
into FreeBSD 4.6.
$^X doesn't always contain a full path in FreeBSD
perl 5.8.0 sets $^X where possible to a full path by asking the operating system.
On FreeBSD the full path of the perl interpreter is found by reading the symlink
/proc/curproc/file. There is a bug on FreeBSD, where the result of reading this
symlink is can be wrong in certain circumstances (see
http://www.freebsd.org/cgi/query-pr.cgi?pr=35703 ). In these cases perl will fall
back to the old behaviour of using C's argv[0] value for $^X.
Perl will no longer be part of "base FreeBSD"
Not as bad as it sounds--what this means is that Perl will no longer be part of the
kernel build system of FreeBSD. Perl will still very probably be part of the
"default install", and in any case the latest version will be in the ports system.
The first FreeBSD version this change will affect is 5.0, all 4.n versions will
keep the status quo.
