+
+
+----------------
+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

+-------------
+Version 5.001
+-------------
+
+Nearly all the changes for 5.001 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.
+
+There were a few that can be construed as enhancements:
+ NETaa13059: now warns of use of \1 where $1 is necessary.
+ NETaa13512: added $SIG{__WARN__} and $SIG{__DIE__} hooks
+ NETaa13520: added closures
+ NETaa13530: scalar keys now resets hash iterator
+ NETaa13641: added Tim's fancy new import whizbangers
+ NETaa13710: cryptswitch needed to be more "useable"
+ NETaa13716: Carp now allows multiple packages to be skipped out of
+ NETaa13716: now counts imported routines as "defined" for redef warnings
+ (and, of course, much of the stuff from the perl5-porters)
+
+NETaa12974: README incorrectly said it was a pre-release.
+Files patched: README
+
+NETaa13033: goto pushed a bogus scope on the context stack.
+From: Steve Vinoski
+Files patched: pp_ctl.c
+ The goto operator pushed an extra bogus scope onto the context stack. (This
+ often didn't matter, since many things pop extra unrecognized scopes off.)
+
+NETaa13034: tried to get valid pointer from undef.
+From: Castor Fu
+Also: Achille Hui, the Day Dreamer
+Also: Eric Arnold
+Files patched: pp_sys.c
+ Now treats undef specially, and calls SvPV_force on any non-numeric scalar
+ value to get a real pointer to somewhere.
+
+NETaa13035: included package info with filehandles.
+From: Jack Shirazi - BIU
+Files patched: pp_hot.c pp_sys.c
+ Now passes a glob to filehandle methods to keep the package info intact.
+
+NETaa13048: didn't give strict vars message on every occurrence.
+From: Doug Campbell
+Files patched: gv.c
+ It now complains about every occurrence. (The bug resulted from an
+ ill-conceived attempt to suppress a duplicate error message in a
+ suboptimal fashion.)
+
+NETaa13052: test for numeric sort sub return value fooled by taint magic.
+From: Peter Jaspers-Fayer
+Files patched: pp_ctl.c sv.h
+ The test to see if the sort sub return value was numeric looked at the
+ public flags rather than the private flags of the SV, so taint magic
+ hid that info from the sort.
+
+NETaa13053: forced a2p to use byacc
+From: Andy Dougherty
+Files patched: MANIFEST x2p/Makefile.SH x2p/a2p.c
+ a2p.c is now pre-byacced and shipped with the kit.
+
+NETaa13055: misnamed constant in previous patch.
+From: Conrad Augustin
+Files patched: op.c op.h toke.c
+ The tokener translates $[ to a constant, but with a special marking in case
+ the constant gets assigned to or localized. Unfortunately, the marking
+ was done with a combination of OPf_SPECIAL and OPf_MOD that was easily
+ spoofed. There is now a private OPpCONST_ARYLEN flag for this purpose.
+
+NETaa13055: use of OPf_SPECIAL for $[ lvaluehood was too fragile.
+Files patched: op.c op.h toke.c
+ (same)
+
+NETaa13056: convert needs to throw away any number info on its list.
+From: Jack Shirazi - BIU
+Files patched: op.c
+ The listiness of the argument list leaked out to the subroutine call because
+ of how prepend_elem and append_elem reuse an existing list. The convert()
+ routine just needs to discard any listiness it finds on its argument.
+
+NETaa13058: AUTOLOAD shouldn't assume size of @_ is meaningful.
+From: Florent Guillaume
+Files patched: ext/DB_File/DB_File.pm ext/Fcntl/Fcntl.pm ext/GDBM_File/GDBM_File.pm ext/Socket/Socket.pm h2xs.SH
+ I just deleted the optimization, which is silly anyway since the eventual
+ subroutine definition is cached.
+
+NETaa13059: now warns of use of \1 where $1 is necessary.
+From: Gustaf Neumann
+Files patched: toke.c
+ Now says
+
+ Can't use \1 to mean $1 in expression at foo line 2
+
+ along with an explanation in perldiag.
+
+NETaa13060: no longer warns on attempt to read <> operator's transition state.
+From: Chaim Frenkel
+Files patched: pp_hot.c
+ No longer warns on <> operator's transitional state.
+
+NETaa13140: warning said $ when @ would be more appropriate.
+From: David J. MacKenzie
+Files patched: op.c pod/perldiag.pod
+ Now says
+
+ (Did you mean $ or @ instead of %?)
+
+ and added more explanation to perldiag.
+
+NETaa13149: was reading freed memory to make incorrect error message.
+Files patched: pp_ctl.c
+ It was reading freed memory to make an error message that would be
+ incorrect in any event because it had the inner filename rather than
+ the outer.
+
+NETaa13149: confess was sometimes less informative than croak
+From: Jack Shirazi
+Files patched: lib/Carp.pm
+ (same)
+
+NETaa13150: stderr needs to be STDERR in package

+
+NETaa13154: array assignment didn't notice package magic.
+From: Brian Reichert
+Files patched: pp_hot.c
+ The list assignment operator looked for only set magic, but set magic is
+ only on the elements of a magical hash, not on the hash as a whole. I made
+ the operator look for any magic at all on the target array or hash.
+
+NETaa13155: &DB::DB left trash on the stack.
+From: Thomas Koenig
+Files patched: lib/perl5db.pl pp_ctl.c
+ The call by pp_dbstate() to &DB::DB left trash on the stack. It now
+ calls DB in list context, and DB returns ().
+
+NETaa13156: lexical variables didn't show up in debugger evals.
+From: Joergen Haegg
+Files patched: op.c
+ The code that searched back up the context stack for the lexical scope
+ outside the eval only partially took into consideration that there
+ might be extra debugger subroutine frames that shouldn't be used, and
+ ended up comparing the wrong statement sequence number to the range of
+ valid sequence numbers for the scope of the lexical variable. (There
+ was also a bug fixed in passing that caused the scope of lexical to go
+ clear to the end of the subroutine even if it was within an inner block.)
+
+NETaa13157: any request for autoloaded DESTROY should create a null one.
+From: Tom Christiansen
+Files patched: lib/AutoLoader.pm
+ If DESTROY.al is not located, it now creates sub DESTROY {} automatically.
+
+NETaa13158: now preserves $@ around destructors while leaving eval.
+From: Tim Bunce
+Files patched: pp_ctl.c

+NETaa13160: clarified behavior of split without arguments

+NETaa13162: eval {} lost list/scalar context

+ Explained that foreach using a lexical is still localized.
+
+NETaa13164: the dot detector for the end of formats was over-rambunctious.
+From: John Stoffel
+Files patched: toke.c
+ The dot detector for the end of formats was over-rambunctious. It would
+ pick up any dot that didn't have a space in front of it.
+
+NETaa13165: do {} while 1 never linked outer block into next chain.
+From: Gisle Aas
+Files patched: op.c
+ When the conditional of do {} while 1; was optimized away, it confused the
+ postfix order construction so that the block that ordinarily sits around the
+ whole loop was never executed. So when the loop tried to unstack between
+ iterations, it got the wrong context, and blew away the lexical variables
+ of the outer scope. Fixed it by introducing a NULL opcode that will be
+ optimized away later.
+
+NETaa13167: coercion was looking at public bits rather than private bits.
+From: Randal L. Schwartz
+Also: Thomas Riechmann
+Also: Shane Castle
+Files patched: sv.c
+ There were some bad ifdefs around the various varieties of set*id(). In
+ addition, tainting was interacting badly with assignment to $> because
+ sv_2iv() was examining SvPOK rather than SvPOKp, and so couldn't coerce
+ a string uid to an integer one.
+
+NETaa13167: had some ifdefs wrong on set*id.
+Files patched: mg.c pp_hot.c

+
+NETaa13168: relaxed test for comparison of new and old fds
+From: Casper H.S. Dik

+
+NETaa13169: autoincrement can corrupt scalar value state.

+
+NETaa13176: ck_rvconst didn't free the const it used up.
+From: Nick Duffek
+Files patched: op.c
+ I checked in many random memory leaks under this bug number, since it
+ was an eval that brought many of them out.

+
+NETaa13177: SCOPE optimization hid line number info
+From: David J. MacKenzie
+Also: Hallvard B Furuseth
+Files patched: op.c
+ Every pass on the syntax tree has to keep track of the current statement.
+ Unfortunately, the single-statement block was optimized into a single
+ statement between the time the variable was parsed and the time the
+ void code scan was done, so that pass didn't see the OP_NEXTSTATE
+ operator, because it has been optimized to an OP_NULL.
+
+ Fortunately, null operands remember what they were, so it was pretty easy
+ to make it set the correct line number anyway.
+
+NETaa13178: some linux doesn't handle nm well

+
+NETaa13180: localized slice now pre-extends array
+From: Larry Schuler
+Files patched: pp.c
+ A localized slice now pre-extends its array to avoid reallocation during

+
+NETaa13181: m//g didn't keep track of whether previous match matched null.
+From: "philippe.verdret"
+Files patched: mg.h pp_hot.c
+ A pattern isn't allowed to match a null string in the same place twice in
+ a row. m//g wasn't keeping track of whether the previous match matched
+ the null string.
+
+NETaa13182: now includes whitespace as a regexp metacharacter.
+From: Larry Wall
+Files patched: toke.c
+ scan_const() now counts " \t\n\r\f\v" as metacharacters when scanning a pattern.
+
+NETaa13183: sv_setsv shouldn't try to clone an object.
+From: Peter Gordon
+Files patched: sv.c
+ The sv_mortalcopy() done by the return in STORE called sv_setsv(),

+ cloning objects.
+
+NETaa13184: bogus warning on quoted signal handler name removed.
+From: Dan Carson

+
+NETaa13187: "${foo::bar}" now counts as mere delimitation, not as a bareword.
+From: Jay Rogers
+Files patched: toke.c
+ "${foo::bar}" now counts as mere delimitation, not as a bareword inside a

+
+NETaa13188: for backward compatibility, looks for "perl -" before "perl".

+Files patched: toke.c
+ Now allows non-whitespace characters on the #! line between the "perl"
+ and the "-".

+Files patched: mg.c
+ Since there was no regexp prior to the "use", it was returning whatever the

+NETaa13305: compiler misoptimized RHS to outside of s/a/print/e
+From: Brian S. Cashman <bsc@umich.edu>

+NETaa13314: assigning mortal to lexical leaks
+From: Larry Wall

+From: Brian Katzung
+Files patched: sv.c doio.c mg.c pp_hot.c pp_sys.c scope.c taint.c

+NETaa13342: grep and map with block would enter block but never leave it.
+From: Ian Phillipps
+Files patched: op.c
+ The compiler use some sort-checking code to handle the arguments of
+ grep and map. Unfortunately, this wiped out the block exit opcode while
+ leaving the block entry opcode. This doesn't matter to sort, but did
+ matter to grep and map. It now leave the block entry intact.
+
+ The reason it worked without the my is because the block entry and exit

+NETaa13366: can't do block scope optimization on $1 et al when tainting.
+From: Andrew Vignaux
+Files patched: toke.c
+ The tainting mechanism assumes that every statement starts out
+ untainted. Unfortunately, the scope removal optimization for very

+
+NETaa13369: # is now a comment character, and \# should be left for regcomp.
+From: Simon Parsons
+Files patched: toke.c
+ It was not skipping the comment when it skipped the white space, and constructed

+NETaa13514: statements before intro of lex var could see lex var
+From: William Setzer
+Files patched: op.c
+ When a lexical variable is declared, introduction is delayed until
+ the start of the next statement, so that any initialization code runs
+ outside the scope of the new variable. Thus,
+
+ my $y = 3;
+ my $y = $y;
+ print $y;
+
+ should print 3. Unfortunately, the declaration was marked with the
+ beginning location at the time that "my $y" was processed instead of
+ when the variable was introduced, so any embedded statements within
+ an anonymous subroutine picked up the wrong "my". The declaration
+ is now labelled correctly when the variable is actually introduced.

New things
----------
The -w switch is much more informative.
meaning the parens are optional. Even subroutines may be called as
list operators if they've already been declared.
- More embeddible. See main.c and embed_h.SH. Multiple interpreters
+ More embeddible. See main.c and embed_h.sh. Multiple interpreters
in the same process are supported (though not with interleaved
execution yet).
this means you can return from it.
Format value lists may be spread over multiple lines by enclosing in
- curlies.
+ a do {} block.
You may now define BEGIN and END subroutines for each package. The BEGIN
subroutine executes the moment it's parsed. The END subroutine executes
Lexical scoping available via "my". eval can see the current lexical
variables.
- Saying "package;" requires explicit package name on global symbols.
-
The preferred package delimiter is now :: rather than '.
tie/untie are now preferred to dbmopen/dbmclose. Multiple DBM
New "and" and "or" operators work just like && and || but with
a precedence lower than comma, so they work better with list operators.
- New functions include: abs(), chr(), uc(), ucfirst(), lc(), lcfirst()
+ New functions include: abs(), chr(), uc(), ucfirst(), lc(), lcfirst(),
+ chomp(), glob()
+
+ require with a number checks to see that the version of Perl that is
+ currently running is at least that number.
+
+ Dynamic loading of external modules is now supported.
+
+ There is a new quote form qw//, which is equivalent to split(' ', q//).
+
+ Assignment of a reference to a glob value now just replaces the
+ single element of the glob corresponding to the reference type:
+ *foo = \$bar, *foo = \&bletch;
+
+ Filehandle methods are now supported:
+ output_autoflush STDOUT 1;
+
+ There is now an "English" module that provides human readable translations
+ for cryptic variable names.
+
+ Autoload stubs can now call the replacement subroutine with goto &realsub.
+
+ Subroutines can be defined lazily in any package by declaring an AUTOLOAD
+ routine, which will be called if a non-existent subroutine is called in
+ that package.
+
+ Several previously added features have been subsumed under the new
+ keywords "use" and "no". Saying "use Module LIST" is short for
+ BEGIN { require Module; import Module LIST; }
+ The "no" keyword is identical except that it calls "unimport" instead.
+ The earlier pragma mechanism now uses this mechanism, and two new
+ modules have been added to the library to implement "use integer"
+ and variations of "use strict vars, refs, subs".
+
+ Variables may now be interpolated literally into a pattern by prefixing
+ them with \Q, which works just like \U, but backwhacks non-alphanumerics
+ instead. There is also a corresponding quotemeta function.
+
+ Any quantifier in a regular expression may now be followed by a ? to
+ indicate that the pattern is supposed to match as little as possible.
+
+ Pattern matches may now be followed by an m or s modifier to explicitly
+ request multiline or singleline semantics. An s modifier makes . match
+ newline.
+
+ Patterns may now contain \A to match only at the beginning of the string,
+ and \Z to match only at the end. These differ from ^ and $ in that
+ they ignore multiline semantics. In addition, \G matches where the
+ last interation of m//g or s///g left off.
+
+ Non-backreference-producing parens of various sorts may now be
+ indicated by placing a ? directly after the opening parenthesis,
+ followed by a character that indicates the purpose of the parens.
+ An :, for instance, indicates simple grouping. (?:a|b|c) will
+ match any of a, b or c without producing a backreference. It does
+ "eat" the input. There are also assertions which do not eat the
+ input but do lookahead for you. (?=stuff) indicates that the next
+ thing must be "stuff". (?!nonsense) indicates that the next thing
+ must not be "nonsense".
+
+ The negation operator now treats non-numeric strings specially.
+ A -"text" is turned into "-text", so that -bareword is the same
+ as "-bareword". If the string already begins with a + or -, it
+ is flipped to the other sign.
Incompatibilities
-----------------
@ now always interpolates an array in double-quotish strings. Some programs
may now need to use backslash to protect any @ that shouldn't interpolate.
+ Ordinary variables starting with underscore are no longer forced into
+ package main.
+
s'$lhs'$rhs' now does no interpolation on either side. It used to
interplolate $lhs but not $rhs.
You can't do a goto into a block that is optimized away. Darn.
It is no longer syntactically legal to use whitespace as the name
- of a variable.
+ of a variable, or as a delimiter for any kind of quote construct.
Some error messages will be different.
taintperl is no longer a separate executable. There is now a -T
switch to turn on tainting when it isn't turned on automatically.
+ Symbols starting with _ are no longer forced into package main, except
+ for $_ itself (and @_, etc.).
+
+ Double-quoted strings may no longer end with an unescaped $ or @.
+
+ Negative array subscripts now count from the end of the array.
+
+ The comma operator in a scalar context is now guaranteed to give a
+ scalar context to its arguments.
+
+ The ** operator now binds more tightly than unary minus.
+
+ Setting $#array lower now discards array elements so that destructors
+ work reasonably.
+
+ delete is not guaranteed to return the old value for tied arrays,
+ since this capability may be onerous for some modules to implement.
+
+ Attempts to set $1 through $9 now result in a run-time error.
