- Version 5.003
- -------------
-
- ***> IMPORTANT NOTICE: <***
- The main reason for this release was to fix a security bug affecting
- suidperl on some systems. If you build suidperl on your system, it
- is strongly recommended that you replace any existing copies with
- version 5.003 or later immediately.
-
- The changes in 5.003 have been held to a minimum, in the hope that this
- will simplify installation and testing at sites which may be affected
- by the security hole in suidperl. In brief, 5.003 does the following:
-
- - Plugs security hole in suidperl mechanism on affected systems
-
- - MakeMaker was also updated to version 5.34, and extension Makefile.PLs
- were modified to match it.
-
- - The following hints files were updated: bsdos.sh, hpux.sh, linux.sh,
- machten.sh, solaris_2.sh
-
- - A fix was added to installperl to insure that file permissions were
- set correctly for the installed C header files.
-
- - t/op/stat.t was modified to work around MachTen's belief that /dev/null
- is a terminal device.
-
- - Incorporation of Perl version information into the VMS' version of
- config.h was changed to make it compatible with the older VAXC.
-
- - Minor fixes were made to VMS-specific C code, and the routine
- VMS::Filespec::rmsexpand was added.
-
- ----------------
- Version 5.002_01
- ----------------
-
- - The EMBED namespace changes are now used by default, in order to better
- segregate Perl's C global symbols from those belonging to embedding
- applications or to libraries. This makes it necessary to rebuild dynamic
- extensions built under previous versions of Perl without the EMBED option.
- The default use of EMBED can be overridden by placing -DNO_EMBED on the
- cc command line.
-
- The EMBED change is the beginning of a general cleanup of C global
- symbols used by Perl, so binary compatibility with previously
- compiled dynamic extensions may be broken again in the next few
- releases.
-
- - Several bugs in the core were fixed, including the following:
- - made sure FILE * for -e temp file was closed only once
- - improved form of single-statement macro definitions to keep
- as many ccs as possible happy
- - fixed file tests to insure that signed values were used when
- computing differences between times.
- - fixed toke.c so implicit loop isn't doubled when perl is
- invoked with both the -p and -n switches
-
- - The new SUBVERSION number has been included in the default value for
- architecture-specific library directories, so development and
- production architecture-dependent libraries can coexist.
-
- - Two new magic variables, $^E and $^O, have been added. $^E contains the
- OS-specific equivalent of $!. $^O contains the name of the operating
- system, in order to make it easily available to Perl code whose behavior
- differs according to its environment. The standard library files have
- been converted to use $^O in preference to $Config{'osname'}.
-
- - A mechanism was added to allow listing of locally applied patches
- in the output of perl -v.
-
- - Miscellaneous minor corrections and updates were made to the documentation.
-
- - Extensive updates were made to the OS/2 and VMS ports
-
- - The following hints file were updated: bsdos.sh, dynixptx.sh,
- irix_6_2.sh, linux.sh, os2.sh
-
- - Several changes were made to standard library files:
- - reduced use of English.pm and $`, $', and $& in library modules,
- since these degrade module loading and evaluation of regular expressions,
- respectively.
- - File/Basename.pm: Added path separator to dirname('.')
- - File/Copy.pm: Added support for VMS and OS/2 system-level copy
- - MakeMaker updated to v5.26
- - Symbol.pm now accepts old (') and new (::) package delimiters
- - Sys/Syslog.pm uses Sys::Hostname only when necessary
- - chat2.pl picks up necessary constants from socket.ph
- - syslog.pl: Corrected thinko 'Socket' --> 'Syslog'
- - xsubpp updated to v1.935
-
-
- - The perlbug utility is now more cautious about sending mail, in order
- to reduce the chance of accidentally send a bug report by giving the
- wrong response to a prompt.
-
- - The -m switch has been added to perldoc, causing it to display the
- Perl code in target file as well as any documentation.
