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.
