| 5 | ***> IMPORTANT NOTICE: <***
|
|---|
| 6 | The main reason for this release was to fix a security bug affecting
|
|---|
| 7 | suidperl on some systems. If you build suidperl on your system, it
|
|---|
| 8 | is strongly recommended that you replace any existing copies with
|
|---|
| 9 | version 5.003 or later immediately.
|
|---|
| 10 |
|
|---|
| 11 | The changes in 5.003 have been held to a minimum, in the hope that this
|
|---|
| 12 | will simplify installation and testing at sites which may be affected
|
|---|
| 13 | by the security hole in suidperl. In brief, 5.003 does the following:
|
|---|
| 14 |
|
|---|
| 15 | - Plugs security hole in suidperl mechanism on affected systems
|
|---|
| 16 |
|
|---|
| 17 | - MakeMaker was also updated to version 5.34, and extension Makefile.PLs
|
|---|
| 18 | were modified to match it.
|
|---|
| 19 |
|
|---|
| 20 | - The following hints files were updated: bsdos.sh, hpux.sh, linux.sh,
|
|---|
| 21 | machten.sh, solaris_2.sh
|
|---|
| 22 |
|
|---|
| 23 | - A fix was added to installperl to insure that file permissions were
|
|---|
| 24 | set correctly for the installed C header files.
|
|---|
| 25 |
|
|---|
| 26 | - t/op/stat.t was modified to work around MachTen's belief that /dev/null
|
|---|
| 27 | is a terminal device.
|
|---|
| 28 |
|
|---|
| 29 | - Incorporation of Perl version information into the VMS' version of
|
|---|
| 30 | config.h was changed to make it compatible with the older VAXC.
|
|---|
| 31 |
|
|---|
| 32 | - Minor fixes were made to VMS-specific C code, and the routine
|
|---|
| 33 | VMS::Filespec::rmsexpand was added.
|
|---|
| 34 |
|
|---|
| 35 | ----------------
|
|---|
| 36 | Version 5.002_01
|
|---|
| 37 | ----------------
|
|---|
| 38 |
|
|---|
| 39 | - The EMBED namespace changes are now used by default, in order to better
|
|---|
| 40 | segregate Perl's C global symbols from those belonging to embedding
|
|---|
| 41 | applications or to libraries. This makes it necessary to rebuild dynamic
|
|---|
| 42 | extensions built under previous versions of Perl without the EMBED option.
|
|---|
| 43 | The default use of EMBED can be overridden by placing -DNO_EMBED on the
|
|---|
| 44 | cc command line.
|
|---|
| 45 |
|
|---|
| 46 | The EMBED change is the beginning of a general cleanup of C global
|
|---|
| 47 | symbols used by Perl, so binary compatibility with previously
|
|---|
| 48 | compiled dynamic extensions may be broken again in the next few
|
|---|
| 49 | releases.
|
|---|
| 50 |
|
|---|
| 51 | - Several bugs in the core were fixed, including the following:
|
|---|
| 52 | - made sure FILE * for -e temp file was closed only once
|
|---|
| 53 | - improved form of single-statement macro definitions to keep
|
|---|
| 54 | as many ccs as possible happy
|
|---|
| 55 | - fixed file tests to insure that signed values were used when
|
|---|
| 56 | computing differences between times.
|
|---|
| 57 | - fixed toke.c so implicit loop isn't doubled when perl is
|
|---|
| 58 | invoked with both the -p and -n switches
|
|---|
| 59 |
|
|---|
| 60 | - The new SUBVERSION number has been included in the default value for
|
|---|
| 61 | architecture-specific library directories, so development and
|
|---|
| 62 | production architecture-dependent libraries can coexist.
|
|---|
| 63 |
|
|---|
| 64 | - Two new magic variables, $^E and $^O, have been added. $^E contains the
|
|---|
| 65 | OS-specific equivalent of $!. $^O contains the name of the operating
|
|---|
| 66 | system, in order to make it easily available to Perl code whose behavior
|
|---|
| 67 | differs according to its environment. The standard library files have
|
|---|
| 68 | been converted to use $^O in preference to $Config{'osname'}.
|
|---|
| 69 |
|
|---|
| 70 | - A mechanism was added to allow listing of locally applied patches
|
|---|
| 71 | in the output of perl -v.
|
|---|
| 72 |
|
|---|
| 73 | - Miscellaneous minor corrections and updates were made to the documentation.
