+
+
+----------------
+Version 5.003_01
+----------------
+
+Version 5.003_01 contains bugfixes and additions accumulated since
+version 5.002_01, since the patch to version 5.003 was deliberately
+kept simple. In addition to numerous small bugfixes in the core,
+library files, and documentation, this patch contains several
+significant revisions, summarized below:
+
+o Visible Changes to Core Functionality
+
+ - A port to Plan9 has been started, and changes are integrated into
+ the standard distribution. As of this release, the Perl core
+ and several common extensions are working.
+
+ - A set of basic methods in the UNIVERSAL class have been added to
+ the Perl core. Since UNIVERSAL is an implicit member of every
+ class's @ISA, the methods can be called via any object.
+
+ - A mandatory warning has been added for 'declarations' of lexical
+ variables using the "my" operator which mask an existing lexical
+ variable declared in the same scope, making the previous variable
+ inaccessible by its name.
+
+ - The "use" and "require" operators have been extended to allow
+ checking of the required module's version. The "use" operator
+ can now be used for an immediate version check of Perl itself.
+
+ - A new "strict" pragma, "strict untie", has been added, which
+ produces an error if a tied value is untied when other references
+ exist to the internal object implementing the tie.
+
+ - Barewords used as associative array keys (i.e. when specifying
+ an associative array element like $foo{__BAR} or on the left
+ side of the => operator) may now begin with an underscore as
+ well as an alphabetic character.
+
+ - Some of the configuration information previously produced by the
+ -v switch has been moved to the -V switch, in order to keep -v
+ output concise.
+
+o Changes in Core Internals
+
+ - Symbol table and method lookups have been made faster.
+
+ - Perl subroutines which just return a constant value are now
+ optimized at compile time into inline constants.
+
+ - Management of keys for associative arrays has been improved to
+ conserve space when the same keys are reused frequently, and
+ to pass true Perl values to tie functions, instead of stringified
+ representations.
+
+ - Messages normally output to stderr may be directed to another
+ stream when Perl is built. This allows some platforms to
+ present diagnostic output in a separate window from normal
+ program results.
+
+ - A bug which caused suiperl to fail silently, albeit securely,
+ in version 5.003 on some systems has been fixed.
+
+ - Management of Unix-style signal handlers via the %SIG associative
+ array has been made safer.
+
+ - Several global C symbols have been renamed to eliminate collisions
+ with system C header files or libraries on some platforms.
+ Unfortunately, this means that dynamic extensions compiled under
+ previous versions of Perl will need to be rebuilt for Perl
+ 5.003_01. We're in the process of cleaning up Perl's C
+ namespace to make it easier to link Perl with other binaries,
+ so this will probably happen again between now and version 5.004.
+ After that, we'll do our best to maintain binary compatibility
+ between versions.
+
+ - An alternate allocation strategy has been added to Perl's
+ optional private memory management routines. This strategy,
+ which may be selected when Perl is built, is designed to
+ conserve memory in programs which allocate many small
+ chunks of memory with sizes near a power of 2, as is often
+ the case in Perl programs.
+
+ - Several memory leaks in the creation and destruction of
+ multiple interpreters have been fixed.
+
+o Changes in the Standard Library and Utilities
+
+ - The Opcode extension, which allows you to control a program's
+ access to Perl operations, has been added to the standard
+ distribution. This extends the work begun in the original
+ Safe extension, and subsumes it. The Safe interface is still
+ available.
+
+ - The IO extension, which provides a set of classes for object-
+ oriented handling of common I/O tasks, has been added to the
+ standard distribution. The IO classes will form the basis
+ for future development of Perl's I/O interface, and will
+ subsume the FileHandle class in the near future. The default
+ class to which all Perl I/O handles belong is now IO::Handle,
+ rather than FileHandle.
+
+ - The ExtUtils::Embed library module, which provides a set
+ of utility function to help in embedding Perl in other
+ applications, has been added to the standard distribution.
+
+ - The Fatal library module, which provides a simple interface
+ for creating "do-or-die" equivalents of existing functions,
+ has been added to the standard distribution.
+
+ - The FindBin library module, which determines the full path
+ to the currently executing program, has been added to the
+ standard distribution.
+
+ - The DB_File extension, and the Getopt::Long, Test::Harness,
+ Text::Tabs, Text::Wrap, Time::Local and sigtrap library modules
+ have been updated to the authors' latest versions.
+
+ - The Carp library module now considers the @ISA chain when
+ determining the caller's package for inclusion in error messages.
+
+ - The h2xs, perlbug, and xsubpp utilities have been updated.
+
+ - The standard Perl debugger has been updated, and the information
+ provided to the debugger when an XSUB is called has been improved,
+ making it possible for alternate debuggers (such as Devel::DProf)
+ to do a better job of tracking XSUB calls.
+
+ - The pod documentation formatting tools in the standard distribution
+ can now handle characters in the input stream whose high bit is set.
+
+ - The cperl-mode EMACS editing mode has been updated.
+
+o Changes in Documentation
+
+ - Typographic and formatting errors have been corrected in the pod
+ documentation for the core and standard library files
+
+ - Explanations of several core operators have been improved
+
+ - The perldebug, perlembed, perlipc, perlsec, and perltrap documents
+ extensively revised.
+
+o Changes in OS-specific and Build-time Support
+
+ - Support for the NeXT platform has been extended through
+ NeXTSTEP/OPENSTEP 4.0, and now includes the ability to create MABs.
+
+ - Support for OS/2 has been extended as well, and now includes
+ options for building a.out binaries.
+
+ - Support for VMS has also been extended, incorporating improved
+ processing of file specification strings, optional suppression of
+ carriage control interpretation for record-structured files,
+ improved support for the -S command line switch, a number of
+ VMS-specific bugfixes, and significantly improved performance
+ in line-oriented reading of files.
+
+ - Several hints files have been added or updated: aux.sh (updated),
+ convexos.sh (updated), irix_4.sh (updated), irix_5.sh (updated),
+ irix_6_2.sh (updated), next_3.sh (updated), next_3_2.sh (new),
+ next_3_3.sh (new), next_4.sh (new), os2/sh (updated),
+ sco.sh (updated), and solaris_2.sh (updated).
+
+ - The test driver for the regression tests now reports when a set
+ of tests have been skipped (presumable because the operation
+ they're designed to test isn't supported on the current system).
+
+-------------
+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.
+
+-------------
+Version 5.002
+-------------
+
+The main enhancement to the Perl core was the addition of prototypes.
+Many of the modules that come with Perl have been extensively upgraded.
+
+Other than that, nearly all the changes for 5.002 were bug fixes of one
+variety or another, so here's the bug list, along with the "resolution"
+for each of them. If you wish to correspond about any of them, please
+include the bug number (if any).
+
+Added APPLLIB_EXP for embedded perl library support.
+Files patched: perl.c
+
+Couldn't define autoloaded routine by assignment to typeglob.
+Files patched: pp_hot.c sv.c
+
+NETaa13525: Tiny patch to fix installman -n

+Files patched: MANIFEST hints/powerux.sh
+
+NETaa13540: VMS uses CLK_TCK for HZ
+Files patched: pp_sys.c
+
+NETaa13721: pad_findlex core dumps on bad CvOUTSIDE()
+From: Carl Witty
+Files patched: op.c sv.c toke.c
+ Each CV has a reference to the CV containing it lexically. Unfortunately,
+ it didn't reference-count this reference, so when the outer CV was freed,
+ we ended up with a pointer to memory that got reused later as some other kind
+ of SV.
+
+NETaa13721: warning suppression
+Files patched: toke.c
+ (same)
+
+NETaa13722: walk.c had inconsistent static declarations
+From: Tim Bunce
+Files patched: x2p/walk.c
+ Consolidated the various declarations and made them consistent with
+ the actual definitions.
+
+NETaa13724: -MPackage=args patch
+From: Tim Bunce
+Files patched: perl.c pod/perlrun.pod
+ Added in the -MPackage=args patch too.
+
+NETaa13729: order-of-evaluation dependency in scope.c on leaving REGCONTEXT
+From: "Jason Shirk"
+Files patched: scope.c
+ Did
+
+ I32 delta = SSPOPINT;
+ savestack_ix -= delta; /* regexp must have croaked */
+
+ instead.
+
+NETaa13731: couldn't assign external lexical array to itself
+From: oneill@cs.sfu.ca
+Files patched: op.c
+ The pad_findmy routine was only checking previous statements for previous
+ mention of external lexicals, so the fact that the current statement
+ already mentioned @list was not noted. It therefore allocated another
+ reference to the outside lexical, and this didn't compare equal when
+ the assigment parsing code was trying to determine whether there was a
+ common variable on either side of the equals. Since it didn't see the
+ same variable, it thought it could avoid making copies of the values on
+ the stack during list assignment. Unfortunately, before using those
+ values, the list assignment has to zero out the target array, which
+ destroys the values.
+
+ The fix was to make pad_findmy search the current statement as well. This
+ was actually a holdover from some old code that was trying to delay
+ introduction of "my" variables until the next statement. This is now
+ done with a different mechanism, so the fix should not adversely affect
+ that.
+
+NETaa13733: s/// doesn't free old string when using copy mode
+From: Larry Wall
+Files patched: pp_ctl.c pp_hot.c
+ When I removed the use of sv_replace(), I simply forgot to free the old char*.
+
+NETaa13736: closures leaked memory
+From: Carl Witty
+Files patched: op.c pp.c
+ This is a specific example of a more general bug, fixed as NETaa13760, having
+ to do with reference counts on comppads.
+
+NETaa13739: XSUB interface caches gimme in case XSUB clobbers it
+From: Dean Roehrich
+Files patched: pp_hot.c
+ Applied suggest patch. Also deleted second gimme declaration as redundant.
+
+NETaa13760: comppad reference counts were inconsistent
+From: Larry Wall
+Files patched: op.c perl.c pp_ctl.c toke.c
+ All official references to comppads are supposed to be through compcv now,
+ but the transformation was not complete, resulting in memory leakage.
+
+NETaa13761: sv_2pv() wrongly preferred IV to NV when SV was readonly
+From: "Jack R. Lawler"
+Files patched: sv.c
+ Okay, I understand how this one happened. This is a case where a
+ beneficial fix uncovered a bug elsewhere. I changed the constant
+ folder to prefer integer results over double if the numbers are the
+ same. In this case, they aren't, but it leaves the integer value there
+ anyway because the storage is already allocated for it, and it *might*
+ be used in an integer context. And since it's producing a constant, it
+ sets READONLY. Unfortunately, sv_2pv() bogusly preferred the integer
+ value to the double when READONLY was set. This never showed up if you
+ just said
+
+ print 1.4142135623731;
+
+ because in that case, there was already a string value.
+
+
+NETaa13772: shmwrite core dumps consistently
+From: Gabe Schaffer
+Files patched: opcode.h opcode.pl
+ The shmwrite operator is a list operator but neglected to push a stack
+ mark beforehand, because an 'm' was missing from opcode.pl.
+
+NETaa13773: $. was misdocumented as read-only.

+
+NETaa13926: commonality was not detected in assignments using COND_EXPR
+From: Mark Hanson
+Files patched: opcode.h opcode.pl
+ The assignment compiler didn't check the 2nd and 3rd args of a ?:
+ for commonality. It still doesn't, but I made ?: into a "dangerous"

+
+NETaa13957: was marking the PUSHMARK as modifiable rather than the arg
+From: David Couture
+Files patched: op.c sv.c
+ It was marking the PUSHMARK as modifiable rather than the arg.
+
+NETaa13962: documentation of behavior of scalar <*> was unclear
+From: Tom Christiansen
+Files patched: pod/perlop.pod
+ Added the following to perlop:
+
+ A glob only evaluates its (embedded) argument when it is starting a new
+ list. All values must be read before it will start over. In a list
+ context this isn't important, because you automatically get them all
+ anyway. In a scalar context, however, the operator returns the next value
+ each time it is called, or a FALSE value if you've just run out. Again,
+ FALSE is returned only once. So if you're expecting a single value from
+ a glob, it is much better to say
+
+ ($file) = <blurch*>;
+
+ than
+
+ $file = <blurch*>;
+
+ because the latter will alternate between returning a filename and
+ returning FALSE.
+
+
+NETaa13986: split ignored /m pattern modifier
+From: Winfried Koenig
+Files patched: pp.c
+ Fixed to work like m// and s///.
+
+NETaa13992: regexp comments not seen after + in non-extended regexp
+From: Mark Knutsen
+Files patched: regcomp.c
+ The code to skip regexp comments was guarded by a conditional that only
+ let it work when /x was in effect.
+
+NETaa14014: use subs should not count as definition, only as declaration
+From: Keith Thompson
+Files patched: sv.c
+ On *foo = \&bar, doesn't set GVf_IMPORTED if foo and bar are in same package.
+
+NETaa14021: sv_inc and sv_dec "upgraded" magical SV to non-magical
+From: Paul A Sand
+Also: Andreas Koenig
+Files patched: sv.c
+ The sv_inc() and sv_dec() routines "upgraded" null magical SVs to non-magical.
+
+NETaa14086: require should check tainting
+From: Karl Simon Berg
+Files patched: pp_ctl.c
+ Since we shouldn't allow tainted requires anyway, it now says:
+
+ Insecure dependency in require while running with -T switch at tst.pl line 1.
+
+NETaa14104: negation fails on magical variables like $1
+From: tim
+Files patched: pp.c
+ Negation was failing on magical values like $1. It was testing the wrong
+ bits and also failed to provide a final "else" if none of the bits matched.
+
+NETaa14107: deep sort return leaked contexts
+From: Quentin Fennessy

+
+ : No. Larry's currently got the patch pumpkin for all such core perl topics.
+
+ I dunno whether you should let me have the patch pumpkin or not. To fix
+ a Sev 2 I just hacked in rudimentary prototypes. :-)
+
+ We can now define true unary subroutines, as well as argumentless
+ subroutines:
+
+ sub baz () { 12; } # Must not have argument
+ sub bar ($) { $_[0] * 7 } # Must have exactly one argument
+ sub foo ($@) { print "@_\n" } # Must have at least one argument
+ foo bar baz / 2 || "oops", "is the answer";
+
+ This prints "42 is the answer" on my machine. That is, it's the same as
+
+ foo( bar( baz() / 2) || "oops", "is the answer");
+
+ Attempting to compile
+
+ foo;
+
+ results in
+
+ Too few arguments for main::foo at ./try line 8, near "foo;"
+
+ Compiling
+
+ bar 1,2,3;
+
+ results in
+
+ Too many arguments for main::bar at ./try line 8, near "foo;"
+
+ But
+
+ @array = ('a','b','c');
+ foo @array, @array;
+
+ prints "3 a b c" because the $ puts the first arg of foo into scalar context.
+
+ The main win at this point is that we can say
+
+ sub AAA () { 1; }
+ sub BBB () { 2; }
+
+ and the user can say AAA + BBB and get 3.
+
+ I'm not quite sure how this interacts with autoloading though. I fear
+ POSIX.pm will need to say
+
+ sub E2BIG ();
+ sub EACCES ();
+ sub EAGAIN ();
+ sub EBADF ();
+ sub EBUSY ();
+ ...
+ sub _SC_STREAM_MAX ();
+ sub _SC_TZNAME_MAX ();
+ sub _SC_VERSION ();
+
+ unless we can figure out how to efficiently declare a default prototype
+ at import time. Meaning, not using eval. Currently
+
+ *foo = \&bar;
+
+ (the ordinary import mechanism) implicitly stubs &bar with no prototype if
+ &bar is not yet declared. It's almost like you want an AUTOPROTO to
+ go with your AUTOLOAD.
+
+ Another thing to rub one's 5 o'clock shadow over is that there's no way
+ to apply a prototype to a method call at compile time.
+
+ And no, I don't want to have the
+
+ sub howabout ($formal, @arguments) { ... }
+
+ argument right now.

+NETaa15179: SvPOK_only shouldn't back off on offset pointer
+From: Gutorm.Hogasen@oslo.teamco.telenor.no
+Files patched: sv.h
+ SvPOK_only() was calling SvOOK_off(), which adjusted the string pointer
+ after tr/// has already acquired it. It shouldn't really be necessary
+ for SvPOK_only() to undo an offset string pointer, since there's no
+ conflict with a possible integer value where the offset is stored.

+ The program

+ for ($i = 0; $i < 100000; $i++) {
+ push @foo, $i;
+ }
+
+ takes about one quarter the memory if the optimizer decides that it can
+ use an integer < comparison rather than floating point. It now does so
+ if one side is an integer constant and the other side a simple variable.
+ This should really help some of our benchmarks. You can still force a
+ floating point comparison by using 100000.0 instead.
