NAME
README.freebsd - Perl version 5 on FreeBSD systems
DESCRIPTION
This document describes various features of FreeBSD that
will affect how Perl version 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.
