-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
-From: Jack Shirazi
-Files patched: lib/File/CheckTree.pm
- Also fixed pl2pm to translate the filehandles to uppercase.
-
-NETaa13150: uppercases stdin, stdout and stderr
-Files patched: pl2pm
- (same)
-
-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
- Applied supplied patch, except the whole second hunk can be replaced with
-
- sv_insert(errsv, 0, 0, message, strlen(message));
-
-NETaa13160: clarified behavior of split without arguments
-From: Harry Edmon
-Files patched: pod/perlfunc.pod
- Clarified the behavior of split without arguments.
-
-NETaa13162: eval {} lost list/scalar context
-From: Dov Grobgeld
-Files patched: op.c
- LEAVETRY didn't propagate number to ENTERTRY.
-
-NETaa13163: clarified documentation of foreach using my variable
-From: Tom Christiansen
-Files patched: pod/perlsyn.pod
- 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
- (same)
-
-NETaa13168: relaxed test for comparison of new and old fds
-From: Casper H.S. Dik
-Files patched: t/lib/posix.t
- I relaxed the comparison to just check that the new fd is greater.
-
-NETaa13169: autoincrement can corrupt scalar value state.
-From: Gisle Aas
-Also: Tom Christiansen
-Files patched: sv.c
- It assumed a PV didn't need to be upgraded to become an NV.
-
-NETaa13169: previous patch could leak a string pointer.
-Files patched: sv.c
- (same)
-
-NETaa13170: symbols missing from global.sym
-From: Tim Bunce
-Files patched: global.sym
- Applied suggested patch.
-
-NETaa13171: \\ in <<'END' shouldn't reduce to \.
-From: Randal L. Schwartz
-Files patched: toke.c
- <<'END' needed to bypass ordinary single-quote processing.
-
-NETaa13172: 'use integer' turned off magical autoincrement.
-From: Erich Rickheit KSC
-Files patched: pp.c pp_hot.c
- The integer versions of the increment and decrement operators were trying too
- hard to be efficient.
-
-NETaa13172: deleted duplicate increment and decrement code
-Files patched: opcode.h opcode.pl pp.c
- (same)
-
-NETaa13173: install should make shared libraries executable.
-From: Brian Grossman
-Also: Dave Nadler
-Also: Eero Pajarre
-Files patched: installperl
- Now gives permission 555 to any file ending with extension specified by $dlext.
-
-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.
-
-NETaa13176: didn't delete XRV for temp ref of destructor.
-Files patched: sv.c
- (same)
-
-NETaa13176: didn't delete op_pmshort in matching operators.
-Files patched: op.c
- (same)
-
-NETaa13176: eval leaked the name of the eval.
-Files patched: scope.c
- (same)
-
-NETaa13176: gp_free didn't free the format.
-Files patched: gv.c
- (same)
-
-NETaa13176: minor leaks in loop exits and constant subscript optimization.
-Files patched: op.c
- (same)
-
-NETaa13176: plugged some duplicate struct allocation memory leaks.
-Files patched: perl.c
- (same)
-
-NETaa13176: sv_clear of an FM didn't clear anything.
-Files patched: sv.c
- (same)
-
-NETaa13176: tr/// didn't mortalize its return value.
-Files patched: pp.c
- (same)
-
-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
-From: Alan Modra
-Files patched: hints/linux.sh
- Applied supplied patch.
-
-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
- the scope of the local.
-
-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(),
- which cloned the object. sv_setsv() shouldn't be in the business of
- cloning objects.
-
-NETaa13184: bogus warning on quoted signal handler name removed.
-From: Dan Carson
-Files patched: toke.c
- Now doesn't complain unless the first non-whitespace character after the =
- is an alphabetic character.
-
-NETaa13186: now croaks on chop($')
-From: Casper H.S. Dik
-Files patched: doop.c
- Now croaks on chop($') and such.
-
-NETaa13187: "${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
- reference block.
-
-NETaa13188: for backward compatibility, looks for "perl -" before "perl".
-From: Russell Mosemann
-Files patched: toke.c
- Now allows non-whitespace characters on the #! line between the "perl"
- and the "-".
-
-NETaa13188: now allows non-whitespace after #!...perl before switches.
-Files patched: toke.c
- (same)
-
-NETaa13189: derivative files need to be removed before recreation
-From: Simon Leinen
-Also: Dick Middleton
-Also: David J. MacKenzie
-Files patched: embed_h.sh x2p/Makefile.SH
- Fixed various little nits as suggested in several messages.
-
-NETaa13190: certain assignments can spoof pod directive recognizer
-From: Ilya Zakharevich
-Files patched: toke.c
- The lexer now only recognizes pod directives where a statement is expected.
-
-NETaa13194: now returns undef when there is no curpm.
-From: lusol@Dillon.CC.Lehigh.EDU
-Files patched: mg.c
- Since there was no regexp prior to the "use", it was returning whatever the
- last successful match was within the "use", because there was no current
- regexp, so it treated it as a normal variable. It now returns undef.
-
-NETaa13195: semop had one S too many.
-From: Joachim Huober
-Files patched: opcode.pl
- The entry in opcode.pl had one too many S's.
-
-NETaa13196: always assumes it's a Perl script if -c is used.
-From: Dan Carson
-Files patched: toke.c
- It now will assume it's a Perl script if the -c switch is used.
-
-NETaa13197: changed implicit -> message to be more understandable.
-From: Bruce Barnett
-Files patched: op.c pod/perldiag.pod
- I changed the error message to be more understandable. It now says
-
- Can't use subscript on sort...
-
-
-NETaa13201: added OPpCONST_ENTERED flag to properly enter filehandle symbols.
-From: E. Jay Berkenbilt
-Also: Tom Christiansen
-Files patched: op.c op.h toke.c
- The grammatical reduction of a print statement didn't properly count
- the filehandle as a symbol reference because it couldn't distinguish
- between a symbol entered earlier in the program and a symbol entered
- for the first time down in the lexer.
-
-NETaa13203: README shouldn't mention uperl.o any more.
-From: Anno Siegel
-Files patched: README
-
-NETaa13204: .= shouldn't warn on uninitialized target.
-From: Pete Peterson
-Files patched: pp_hot.c
- No longer warns on uninitialized target of .= operator.
-
-NETaa13206: handy macros in XSUB.h
-From: Tim Bunce
-Files patched: XSUB.h
- Added suggested macros.
-
-NETaa13228: commonality checker didn't treat lexicals as variables.
-From: mcook@cognex.com
-Files patched: op.c opcode.pl
- The list assignment operator tries to avoid unnecessary copies by doing the
- assignment directly if there are no common variables on either side of the
- equals. Unfortunately, the code that decided that only recognized references
- to dynamic variables, not lexical variables.
-
-NETaa13229: fixed sign stuff for complement, integer coercion.
-From: Larry Wall
-Files patched: perl.h pp.c sv.c
- Fixed ~0 and integer coercions.
-
-NETaa13230: no longer tries to reuse scratchpad temps if tainting in effect.
-From: Luca Fini
-Files patched: op.c
- I haven't reproduced it, but I believe the problem is the reuse of scratchpad
- temporaries between statements. I've made it not try to reuse them if
- tainting is in effect.
-
-NETaa13231: *foo = *bar now prevents typo warnings on "foo"
-From: Robin Barker
-Files patched: sv.c
- Aliasing of the form *foo = *bar is now protected from the typo warnings.
- Previously only the *foo = \$bar form was.
-
-NETaa13235: require BAREWORD now introduces package name immediately.
-From: Larry Wall
-Files patched: toke.c
- require BAREWORD now introduces package name immediately. This lets the
- method intuit code work right even though the require hasn't actually run
- yet.
-
-NETaa13289: didn't calculate correctly using arybase.
-From: Jared Rhine
-Files patched: pp.c pp_hot.c
- The runtime code didn't use curcop->cop_arybase correctly.
-
-NETaa13301: store now throws exception on error
-From: Barry Friedman
-Files patched: ext/GDBM_File/GDBM_File.xs ext/NDBM_File/NDBM_File.xs ext/ODBM_File/ODBM_File.xs ext/SDBM_File/SDBM_File.xs
- Changed warn to croak in ext/*DBM_File/*.xs.
-
-NETaa13302: ctime now takes Time_t rather than Time_t*.
-From: Rodger Anderson
-Files patched: ext/POSIX/POSIX.xs
- Now declares a Time_t and takes the address of that in CODE.
-
-NETaa13302: shorter way to do this patch
-Files patched: ext/POSIX/POSIX.xs
- (same)
-
-NETaa13304: could feed too large $@ back into croak, whereupon it croaked.
-From: Larry Wall
-Files patched: perl.c
- callist() could feed $@ back into croak with more than a bare %s. (croak()
- handles long strings with a bare %s okay.)
-
-NETaa13305: compiler misoptimized RHS to outside of s/a/print/e
-From: Brian S. Cashman <bsc@umich.edu>
-Files patched: op.c
- The syntax tree was being misconstructed because the compiler felt that
- the RHS was invariant, so it did it outside the s///.
-
-NETaa13314: assigning mortal to lexical leaks
-From: Larry Wall
-Files patched: sv.c
- In stealing strings, sv_setsv was checking SvPOK to see if it should free
- the destination string. It should have been checking SvPVX.
-
-NETaa13316: wait4pid now recalled when errno == EINTR
-From: Robert J. Pankratz
-Files patched: pp_sys.c util.c
- system() and the close() of a piped open now recall wait4pid if it returned
- prematurely with errno == EINTR.
-
-NETaa13329: needed to localize taint magic
-From: Brian Katzung
-Files patched: sv.c doio.c mg.c pp_hot.c pp_sys.c scope.c taint.c
- Taint magic is now localized better, though I had to resort to a kludge
- to allow a value to be both tainted and untainted simultaneously during
- the assignment of
-
- local $foo = $_[0];
-
- when $_[0] is a reference to the variable $foo already.
-
-NETaa13341: clarified interaction of AnyDBM_File::ISA and "use"
-From: Ian Phillipps
-Files patched: pod/modpods/AnyDBMFile.pod
- The doc was misleading.
-
-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
- were optimized away to an OP_SCOPE, which it doesn't matter if it's there
- or not.
-
-NETaa13343: goto needed to longjmp when in a signal handler.
-From: Robert Partington
-Files patched: pp_ctl.c
- goto needed to longjmp() when in a signal handler to get back into the
- right run() context.
-
-
-NETaa13344: strict vars shouldn't apply to globs or filehandles.
-From: Andrew Wilcox
-Files patched: gv.c
- Filehandles and globs will be excepted from "strict vars", so that you can
- do the standard Perl 4 trick of
-
- use strict;
- sub foo {
- local(*IN);
- open(IN,"file");
- }
-
-
-NETaa13345: assert.pl didn't use package DB
-From: Hans Mulder
-Files patched: lib/assert.pl
- Now it does.
-
-NETaa13348: av_undef didn't free scalar representing $#foo.
-From: David Filo
-Files patched: av.c
- av_undef didn't free scalar representing $#foo.
-
-NETaa13349: sort sub accumulated save stack entries
-From: David Filo
-Files patched: pp_ctl.c
- COMMON only gets set if assigning to @_, which is reasonable. Most of the
- problem was a memory leak.
-
-NETaa13351: didn't treat indirect filehandles as references.
-From: Andy Dougherty
-Files patched: op.c
- Now produces
-
- Can't use an undefined value as a symbol reference at ./foo line 3.
-
-
-NETaa13352: OP_SCOPE allocated as UNOP rather than LISTOP.
-From: Andy Dougherty
-Files patched: op.c
-
-NETaa13353: scope() didn't release filegv on OP_SCOPE optimization.
-From: Larry Wall
-Files patched: op.c
- When scope() nulled out a NEXTSTATE, it didn't release its filegv reference.
-
-NETaa13355: hv_delete now avoids useless mortalcopy
-From: Larry Wall
-Files patched: hv.c op.c pp.c pp_ctl.c proto.h scope.c util.c
- hv_delete now avoids useless mortalcopy.
-
-
-NETaa13359: comma operator section missing its heading
-From: Larry Wall
-Files patched: pod/perlop.pod
-
-NETaa13359: random typo
-Files patched: pod/perldiag.pod
-
-NETaa13360: code to handle partial vec values was bogus.
-From: Conrad Augustin
-Files patched: pp.c
- The code that Mark J. added a long time ago to handle values that were partially
- off the end of the string was incorrect.
-
-NETaa13361: made it not interpolate inside regexp comments
-From: Martin Jost
-Files patched: toke.c
- To avoid surprising people, it no longer interpolates inside regexp
- comments.
-
-NETaa13362: ${q[1]} should be interpreted like it used to
-From: Hans Mulder
-Files patched: toke.c
- Now resolves ${keyword[1]} to $keyword[1] and warns if -w. Likewise for {}.
-
-NETaa13363: meaning of repeated search chars undocumented in tr///
-From: Stephen P. Potter
-Files patched: pod/perlop.pod
- Documented that repeated characters use the first translation given.
-
-NETaa13365: if closedir fails, don't try it again.
-From: Frank Crawford
-Files patched: pp_sys.c
- Now does not attempt to closedir a second time.
-
-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
- short blocks removed the statementhood of statements that were
- attempting to read $1 as an untainted value, with the effect that $1
- appeared to be tainted anyway. The optimization is now disabled when
- tainting and the block contains $1 (or equivalent).
-
-NETaa13366: fixed this a better way in toke.c.
-Files patched: op.c
- (same)
-
-NETaa13366: need to disable scope optimization when tainting.
-Files patched: op.c
- (same)
-
-NETaa13367: Did a SvCUR_set without nulling out final char.
-From: "Rob Henderson" <robh@cs.indiana.edu>
-Files patched: doop.c pp.c pp_sys.c
- When do_vop set the length on its result string it neglected to null-terminate
- it.
-
-NETaa13368: bigrat::norm sometimes chucked sign
-From: Greg Kuperberg
-Files patched: lib/bigrat.pl
- The normalization routine was assuming that the gcd of two numbers was
- never negative, and based on that assumption managed to move the sign
- to the denominator, where it was deleted on the assumption that the
- denominator is always positive.
-
-NETaa13368: botched previous patch
-Files patched: lib/bigrat.pl
- (same)
-
-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
- an opcode that tried to match a null string. Unfortunately, the previous
- star tried to use the first character of the null string to optimize where
- to recurse, so it never matched.
-
-NETaa13369: comment after regexp quantifier induced non-match.
-Files patched: regcomp.c
- (same)
-
-NETaa13370: some code assumed SvCUR was of type int.
-From: Spider Boardman
-Files patched: pp_sys.c
- Did something similar to the proposed patch. I also fixed the problem that
- it assumed the type of SvCUR was int. And fixed get{peer,sock}name the
- same way.

-NETaa13375: sometimes dontbother wasn't added back into strend.
-From: Jamshid Afshar
-Files patched: regexec.c
- When the /g modifier was used, the regular expression code would calculate

-NETaa13376: suspected indirect objecthood prevented recognition of lexical.
-From: Gisle.Aas@nr.no
-Files patched: toke.c
- When $data[0] is used in a spot that might be an indirect object, the lexer
- was getting confused over the rule that says the $data in $$data[0] isn't
- an array element. (The lexer uses XREF state for both indirect objects
- and for variables used as names.)

-From: Philip Hazel
-Files patched: pod/perlre.pod
- Removed bogus brackets. Now reads:

-NETaa13442: couldn't find name of copy of deleted symbol table entry
-From: Spider Boardman
-Files patched: gv.c gv.h
- I did a much simpler fix. When gp_free notices that it's freeing the
- master GV, it nulls out gp_egv. The GvENAME and GvESTASH macros know
- to revert to gv if egv is null.

- This has the advantage of not creating a reference loop.

-NETaa13451: in scalar context, pp_entersub now guarantees one item from XSUB
-From: Nick Gianniotis
-Files patched: pp_hot.c
- The pp_entersub routine now guarantees that an XSUB in scalar context

-NETaa13475: \(@ary) now treats array as list of scalars

-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.

-NETaa13687: new Exporter.pm
-From: Tim Bunce
-Files patched: lib/Exporter.pm
- Added suggested changes, except for @EXPORTABLE, because it looks too much
- like @EXPORTTABLE. Decided to stick with @EXPORT_OK because it looks more
- like an adjunct. Also added an export_tags routine. The keys in the
- %EXPORT_TAGS hash no longer use colons, to make the initializers prettier.

+Please note: This file provides a summary of significant changes
+between versions and sub-versions of Perl, not a complete list
+of each modification. If you'd like more detailed information,
+please consult the comments in the patches on which the relevant
+release of Perl is based. (Patches can be found on any CPAN
+site, in the .../src/5.0 directory for full version releases,
+or in the .../src/5/0/unsupported directory for sub-version
+releases.)
-NETaa13716: now counts imported routines as "defined" for redef warnings
-Files patched: op.c sv.c
- (same)
+----------------
+Version 5.003_03
+----------------
--------------
-Version 5.000
--------------
+Most of the changes in 5.003_03 are to make the build and installation
+process more robust. The details are described below. A very brief
+summary is:
-New things
-----------
- The -w switch is much more informative.
+o Visible Changes to Core Functionality
- References. See t/op/ref.t for examples. All entities in Perl 5 are
- reference counted so that it knows when each item should be destroyed.
+ -Support for tied filehandles.
- Objects. See t/op/ref.t for examples.
+o Configure enhancements
- => is now a synonym for comma. This is useful as documentation for
- arguments that come in pairs, such as initializers for associative arrays,
- or named arguments to a subroutine.
+ -How to build and install a shared libperl.so is now documented
+ and supported, though it's not the default for most platforms.
- All functions have been turned into list operators or unary operators,
- 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
- in the same process are supported (though not with interleaved
- execution yet).
-
- The interpreter is now flattened out. Compare Perl 4's eval.c with
- the perl 5's pp.c. Compare Perl 4's 900 line interpreter loop in cmd.c
- with Perl 5's 1 line interpreter loop in run.c. Eventually we'll make
- everything non-blocking so we can interface nicely with a scheduler.
-
- eval is now treated more like a subroutine call. Among other things,
- this means you can return from it.
+o Bug fixes
- Format value lists may be spread over multiple lines by enclosing in
- a do {} block.
+ -Support bit operations on strings longer than 15 bytes.
- You may now define BEGIN and END subroutines for each package. The BEGIN
- subroutine executes the moment it's parsed. The END subroutine executes
- just before exiting.
+ -If a regex supplied to split() contains paranthesized subpatterns
+ that can result in null matches, perl no longer coredumps.
- Flags on the #! line are interpreted even if the script wasn't
- executed directly. (And even if the script was located by "perl -x"!)
+ -Fix problems with each() on tied hashes.
- The ?: operator is now legal as an lvalue.
+ -Make h2ph architecture-independent by using Config at run-time
+ rather than extraction time.
- List context now propagates to the right side of && and ||, as well
- as the 2nd and 3rd arguments to ?:.
+o Specific Changes
- The "defined" function can now take a general expression.
+Here are the specific file-by-file changes.
- Lexical scoping available via "my". eval can see the current lexical
- variables.
+# This is my patch perl5.003_03.pat to perl5.003_02
+# The full description is below.
+# Please execute the following commands before applying this patch.
+# (You can feed this patch to 'sh' to do so.)
+# Andy Dougherty <doughera@lafcol.lafayette.edu>
- The preferred package delimiter is now :: rather than '.
+# Absorbed into Changes5.002
+rm -f Changes.Conf
- tie/untie are now preferred to dbmopen/dbmclose. Multiple DBM
- implementations are allowed in the same executable, so you can
- write scripts to interchange data among different formats.
+# Not needed.
+rm -f ext/POSIX/mkposixman.pl
- New "and" and "or" operators work just like && and || but with
- a precedence lower than comma, so they work better with list operators.
+# Moved to README.os2. I'm not sure why the README files are
+# here rather than in the appropriate subdirectories.
+rm -f os2/README
- New functions include: abs(), chr(), uc(), ucfirst(), lc(), lcfirst(),
- chomp(), glob()
+# Not needed.
+rm -f pod/Makefile.PL
- require with a number checks to see that the version of Perl that is
- currently running is at least that number.
+# New test for bit ops.
+touch t/op/bob.t
- Dynamic loading of external modules is now supported.
+# Patches that create new tests don't always make them executable.
+chmod +x t/*/*.t
- There is a new quote form qw//, which is equivalent to split(' ', q//).
+# Create a new directory for Porting and Patching info.
+mkdir Porting
- 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;
+exit 0
- Filehandle methods are now supported:
- output_autoflush STDOUT 1;
+This is patch perl5.003_03.pat to perl version 5.003_02.
+This takes you from 5.003_02 to 5.003_03.
- There is now an "English" module that provides human readable translations
- for cryptic variable names.
+To apply this patch, run the above commands,
+cd to your perl source directory and then type
- Autoload stubs can now call the replacement subroutine with goto &realsub.
+ patch -p1 -N < perl5.003_03.pat
- 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.
+The changes are described after each /^Index/ line below. This is
+designed so you can examine each change with a command such as
- 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".
+ csplit -k perl5.003_03.pat '/^Index:/' '{99}'
- 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.
+Patch and enjoy,
- 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.
+ Andy Dougherty doughera@lafcol.lafayette.edu
+ Dept. of Physics
+ Lafayette College, Easton PA 18042
- 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.
+Index: Changes
- 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.
+ Include 5.003_03 change notes.
- 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".
+ Move older change notes to separate files.
- 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.
+Index: Changes5.000
-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.
+ New file. Changes from perl4.036 to 5.000.
- Ordinary variables starting with underscore are no longer forced into
- package main.
+Index: Changes5.001
- s'$lhs'$rhs' now does no interpolation on either side. It used to
- interplolate $lhs but not $rhs.
+ New file. Changes from 5.000 to 5.001
- The second and third arguments of splice are now evaluated in scalar
- context (like the book says) rather than list context.
+Index: Changes5.002
- Saying "shift @foo + 20" is now a semantic error because of precedence.
+ New file. Changes from 5.001 to 5.002
- "open FOO || die" is now incorrect. You need parens around the filehandle.
+Index: Changes5.003
- The elements of argument lists for formats are now evaluated in list
- context. This means you can interpolate list values now.
+ New file. Changes from 5.002 to 5.003
- You can't do a goto into a block that is optimized away. Darn.
+Index: Configure
- It is no longer syntactically legal to use whitespace as the name
- of a variable, or as a delimiter for any kind of quote construct.
+ Relaxed warning about ksh on exotic machines.
- Some error messages will be different.
+ Changed usesafe to useopcode.
- The caller function now returns a false value in a scalar context if there
- is no caller. This lets library files determine if they're being required.
+ Add search for gzip and zip.
- m//g now attaches its state to the searched string rather than the
- regular expression.
+ Look more carefully for $sh (the Bourne-ish shell).
+ Use that info to set $startsh correctly.
- "reverse" is no longer allowed as the name of a sort subroutine.
+ Change prompts for PerlIO interface. See INSTALL
+ for how this is supposed to work. The default is
+ still the same as in 5.003_02, namely don't use
+ any fancy new PerlIO stuff.
- taintperl is no longer a separate executable. There is now a -T
- switch to turn on tainting when it isn't turned on automatically.
+ Don't look for sigvec() since we don't actually use it.
+ (Plus, it used to print an alarming misleading message about
+ race conditions.)
- Symbols starting with _ are no longer forced into package main, except
- for $_ itself (and @_, etc.).
+ Look for stdio's _filbuf under the possible names of
+ _filbuf, __filbuf, and _fill.
- Double-quoted strings may no longer end with an unescaped $ or @.
+ New $useshrplib variable to control whether we build a shared
+ libperl.so. The name of the library is in $libperl.
+ Always install it in $installarchlib/CORE/$libperl.
- Negative array subscripts now count from the end of the array.
+ Check for <sys/resource.h> and <sys/wait.h> for NetBSD.
- The comma operator in a scalar context is now guaranteed to give a
- scalar context to its arguments.
+ Replace old $altmake stuff with newer autoconf-ish
+ $make_set_make, which checks if $make sets $(MAKE). Now you
+ choose an alternate make with sh Configure -Dmake=gmake (or
+ whatever).
- The ** operator now binds more tightly than unary minus.
+ Remove 'ln' for the list of essential commands. Simulate
+ it with 'cp' if necessary.
- Setting $#array lower now discards array elements so that destructors
- work reasonably.
+ Change `logname` prompts to handle extra gratuitous spaces in
+ Ultrix output.
- delete is not guaranteed to return the old value for tied arrays,
- since this capability may be onerous for some modules to implement.
+ Autodetect os2.
- Attempts to set $1 through $9 now result in a run-time error.
+ Fix silly bug in checking for fully-qualified names in /etc/hosts.
+
+ Generalize Gconvert tests. Give correct and more useful
+ error messages.
+
+ Use $obj_ext instead of literal '.o' in the dynaloader test.
+
+ Include appropriate header files in bcopy() and memcpy()
+ tests. Note whether memmove is available.
+
+ Check whether struct sigaction works (needed for Solaris 2.5
+ with -Xc).
+
+ Include appropriate header files for randbits test.
+
+Index: INSTALL
+
+ Add note about space requirements.
+
+ Update to match Configure changes (Opcode vs. Safe,
+ useperlio, useshrplib, etc.)
+
+ Reorganize the structure of some of the hints.
+
+ Miscellaneous clarifications.
+
+Index: MANIFEST
+
+ Updated. 5.003_02 introduced some massive patches, mostly
+ due to spacing changes. I didn't bother to sort them all out;
+ I just started with 5.003's MANIEFST.
+
+Index: Makefile.SH
+
+ Support the new simplified shared libperl mechanism.
+
+ Use new $make_set_make directive.
+
+ Remove redundant libperl Make variable.
+
+ Remove unnecessary MAB variable.
+
+ Remove dependency of minitest on lib/Config.pm, since it could
+ well have been a failure of configpm that inspired testing
+ miniperl in the first place!
+
+Index: Porting/Glossary
+
+ New file describing all the config.sh variables.
+ Eventually, I hope to fill this directory with other useful
+ stuff.
+
+Index: README.os2
+
+ Replace old README.os2 with more up-to-date os2/README.
+
+Index: config_H
+
+ Updated to match current Configure and config_h.SH.
+ Some rearrangement of parts has occurred due to new
+ dependencies in the metaconfig units.
+
+Index: config_h.SH
+
+ Updated to match current Configure and config_h.SH.
+ Some rearrangement of parts has occurred due to new
+ dependencies in the metaconfig units.
+
+ Include full descriptions of ARCHLIB, OLDARCHLIB, PRIVLIB,
+ SITEARCH, and SITELIB. Previous versions just included the
+ ~-expanded names (with unhelpful descriptions). No functionality
+ is changed, but maybe it's a little better documented now.
+
+Index: doio.c
+
+ Possibly Include <signal.h> and <unistd.h>
+
+Index: doop.c
+
+ No longer prefer bcmp over memcmp when order doesn't matter.
+
+ Support bit operations on strings longer than 15 bytes.
+
+Index: embed.h
+
+ Auto-generated.
+
+Index: embed.pl
+
+ Expand warning at the top.
+
+Index: ext/IO/IO.pm
+
+ Clean up docmentation installation errors.
+
+Index: ext/IO/lib/IO/Seekable.pm
+
+ Clean up docmentation installation errors.

+Index: ext/IO/lib/IO/Select.pm
+
+ Clean up docmentation installation errors.
+
+Index: ext/Opcode/Opcode.xs
+
+ Add support for tied filehandles.
+
+Index: ext/SDBM_File/sdbm/sdbm.h
+
+ Change the Mymalloc to match Perl_malloc in perl.h.
+
+Index: ext/util/make_ext
+
+ Typo change.
+ Get rid of unused altmake.
+
+Index: global.sym
+
+ Fix problems with each() on tied hashes.
+
+Index: handy.h
+
+ Change safe*alloc functions to have prototypes that
+ match the system's malloc and free types. That is, use
+ Malloc_t instead of char *, and Free_t instead of void.
+ This is necessary so . . .
+
+ Safefree cast matches type of free() whether it's perl's
+ malloc/free or the system's malloc/free.
+
+Index: hints/README.hints
+
+ Remove out-of-date info.
+
+ Document a bit about how hint files work.
+
+Index: hints/aix.sh
+
+ qmaxmem hint doesn't apply to gcc.
+
+Index: hints/dgux.sh
+
+ Configure will now automatically detect shared libperl stuff.
+
+Index: hints/dynixptx.sh
+
+ Fix typo in comment.
+
+ Configure will now automatically detect shared libperl stuff.
+
+Index: hints/epix.sh
+
+ Use glibpth instead of libpth. This allows Configure to
+ add local directories, such as /opt/local/lib, etc.
+
+Index: hints/irix_6_2.sh
+
+ Include some info on cc -n32 compile.
+
+Index: hints/linux.sh
+
+ Configure now tests gcvt() more thoroughly.
+
+Index: hints/machten_2.sh
+
+ Update where to find dld.
+
+Index: hints/mips.sh
+
+ Use glibpth instead of libpth.
+
+Index: hints/next_3.sh
+
+ Build up $mab dynamically. Since $mab isn't used anywhere
+ anymore, this is useless. However, $mab was never used for
+ next_3.sh anyway, so there's been no change in functionality.
+
+Index: hints/next_4.sh
+
+ Get rid of extraneous isnext_4 variable. Configure and
+ Makefile.SH will use $osname and $osvers instead.
+
+ Build up $mab dynamically based on available architectures.
+
+ Absorb $mab into ccflags and ccdlflags. I hope that will
+ cover everything. (Configure should automatically remove
+ the -arch stuff from cppflags.)
+
+ Configure now knows next4 needs to use a shared libperl.5.so.
+
+ Allow users to use -Dprefix.
+
+Index: hints/os2.sh
+
+ Try to update to reflect newer shared libperl stuff.
+ I probably goofed :-).
+
+Index: hints/sco.sh
+
+ Additional notes on using icc.
+
+ Additional flags for dynamic loading.
+
+Index: hints/solaris_2.sh
+
+ Perl.h no longer prefers bcmp, so it's again ok if Configure
+ finds them, since perl will prefer the mem* versions anyway.
+
+Index: hints/sunos_4_0.sh
+
+ Don't include <unistd.h>
+
+Index: hints/sunos_4_1.sh
+
+ Add brief note about GNU as and ld.
+
+ Don't include <unistd.h>
+
+ Add notes about WHOA THERE messages.
+
+Index: hints/titanos.sh
+
+ Include sfio in libswanted.
+
+ Don't set libpth any more.
+
+Index: hints/umips.sh
+
+ New hint file.
+
+Index: hv.c
+
+ Use memcmp even in cases where ordering doesn't matter.
+
+ Fix problems with each() on tied hashes.
+
+Index: installperl
+
+ Simplify installation of shared libperl.so.
+
+ Avoid reaching Command Failed!!! with /usr/bin/perl.
+
+Index: lib/AutoSplit.pm
+
+ Clean up docmentation installation errors.
+
+Index: lib/ExtUtils/MM_Unix.pm
+
+ Remove MAB references.
+
+ Use 'useshrplib' instead of 'd_shrplib'
+
+Index: lib/ExtUtils/MakeMaker.pm
+
+ Remove mab references.
+
+Index: lib/FindBin.pm
+
+ Clean up docmentation installation errors.
+
+Index: lib/Symbol.pm
+
+ Put back in the BEGIN { require 5.002; }. The version in
+ 5.003_02 wouldn't work in 5.002 anyway. Further, the whole
+ point of the construct is to catch 5.001m, so we can't use
+ syntax introduced after 5.001m to do that.
+
+Index: lib/Text/Wrap.pm
+
+ Remove double 'use strict'.
+
+Index: lib/perl5db.pl
+
+ Add explicit '&' to avoid warnings under strict refs.
+
+Index: lib/sigtrap.pm
+
+ Clean up docmentation installation errors.
+
+Index: makedepend.SH
+
+ Use Configure's $sh and $make_set_make variables.
+
+Index: mg.c
+
+ Include <unistd.h>
+
+ Use Safefree() macro instead of safefree() function with
+ a (possibly) incorrect cast. The whole point of the
+ Safefree() macro is that it does the correct cast for you.
+
+
+Index: patchlevel.h
+
+ Change to SUBVERSION 3.
+
+Index: perl.c
+
+ Include <unistd.h>
+
+Index: perl.h
+
+ No longer prefer bcmp slightly for comparisons that don't care
+ about ordering.
+
+ Rely on Configure setting SH_PATH.
+
+ Change the function name to Pause() instead of pause() to
+ avoid potential prototype problems. (This naming convention
+ is similar to the Fwrite and Fflush macros.)
+
+ Fix problems with each() on tied hashes.
+
+ Work around crypt prototype problem on NeXT.
+
+Index: perlio.c
+
+ Fixes to support non-std stdio.
+
+Index: perlio.h
+
+ Try to document the various #defines a bit. This is far from
+ finished.
+
+ Remove a lot of trailing whitespace. (It's of no consequence, but
+ but I'm not going to redo the patch just to put back in the trailing
+ whitespace either.)
+
+Index: perlsdio.h
+
+ Fixes to support non-std stdio.

+----------------
+Version 5.003_02
+----------------
+o Visible Changes to Core Functionality
+ - Redefining constant subs, or changing sub's prototype now give warnings.
+ - Fixes for ++/-- of values close to max/min size of an integer
+ - Warning for un-qualified bareword as handler in $SIG{}.
+ - UNIVERSAL::isa can now be called as static method.
+
+o Changes in Core Internals
+ - PerlIO abstraction added.
+ Perl core and standard extensions no longer assume ANSI C's stdio is IO
+ mechanism, Default Configure mode is still to use stdio via set of C macros.
+ Alternate modes are to use stdio via one perlio.c module, or
+ to use sfio if available.
+
+ - Several bug fixs from perl5-porters
+ - Make sources non-ANSI C correct again.
+ - SUPER in gv.c
+ - Last of shared-hash-key patches
+ - eval '(0,1..3)'; # --> SegFault
+ - coredumps after simple subsitutes.
+ - Correction to UNIVERSAL::VERSION docs.
+ - Fixed io_udp test.
+ - Fixed another abuse of malloc'ed memory.
+ - Enabled DEBUGING_MSTATS whenever perl's malloc() is used.
+ - Reverted to default of not hiding perl's malloc (if used).
+
+o Changes in the Standard Library and Utilities
+ - Fixed MakeMaker for static SDBM and builing in a link tree.
+ - Upgraded to IO-1.09, and includes latest (still experimental) IO::Select.
+ - Documentation/test tweak to DB_File
+ - h2xs upgrade to allow use C::Scan module
+
+o Changes in OS-specific and Build-time Support
+ - Attempted to re-created 5.003_01's NeXT support with metaconfig units.
+ - Updated MANIFEST
+ - make minitest now depends on lib/Config.pm, as some of tests require it.
+ - Included latest plan9 sub-directory
+ - Applied OS/2 patches.
+ - Typo patch for VMS.
+
+----------------
+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).
