+Version 5.004_64 Developer release working toward 5.005
+----------------
+
+[Put changes here. Should we go back and put in changes for
+_51 onwards?]
+
+----------------
+Version 5.004_50 First developer release towards 5.005
+----------------
+
+Maintenance of the 5.004 version of perl continues with the 5.004_xx
+series, where 'xx' is <= 49. Development of the next version, 5.005,
+starts with 5.004_50.
-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

-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

-
-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
- the end of $' too short by the minimum number of characters the pattern could
- match.
-
-NETaa13375: sv_setpvn now disallows negative length.
-Files patched: sv.c
- (same)
-
-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.)
-
-NETaa13377: -I processesing ate remainder of #! line.
-From: Darrell Schiebel
-Files patched: perl.c
- I made the -I processing in moreswitches look for the end of the string,
- delimited by whitespace.
-
-NETaa13379: ${foo} now treated the same outside quotes as inside
-From: Hans Mulder
-Files patched: toke.c
- ${bareword} is now treated the same outside quotes as inside.
-
-NETaa13379: previous fix for this bug was botched
-Files patched: toke.c
- (same)
-
-NETaa13381: TEST should check for perl link

-NETaa13388: constant folding now prefers integer results over double
-From: Ilya Zakharevich
-Files patched: op.c
- Constant folding now prefers integer results over double.
-
-NETaa13389: now treats . and exec as shell metathingies

-From: Larry Wall
-Files patched: pp_ctl.c
-
-NETaa13396: $^ coredumps at end of string
-From: Paul Rogers
-Files patched: toke.c
- The scan_ident() didn't check for a null following $^.
-
-NETaa13397: improved error messages when operator expected
-From: Larry Wall
-Files patched: toke.c
- Added message (Do you need to predeclare BAR?). Also fixed the missing
- semicolon message.

-NETaa13401: Boyer-Moore code attempts to compile string longer than 255.
-From: Kyriakos Georgiou
-Files patched: util.c
- The Boyer-Moore table uses unsigned char offsets, but the BM compiler wasn't
- rejecting strings longer than 255 chars, and was miscompiling them.

-NETaa13403: missing a $ on variable name

-
-NETaa13406: didn't wipe out dead match when proceeding to next BRANCH
-From: Michael P. Clemens

-NETaa13407: overload upgrade
-From: owner-perl5-porters@nicoh.com

-Files patched: MANIFEST gv.c lib/Math/BigInt.pm perl.h pod/perlovl.pod pp.c pp.h pp_hot.c sv.c t/lib/bigintpm.t t/op/overload.t
- Applied supplied patch, and fixed bug induced by use of sv_setsv to do
- a deep copy, since sv_setsv no longer copies objecthood.
-
-NETaa13409: sv_gets tries to grow string at EOF
-From: Harold O Morris
-Files patched: sv.c
- Applied suggested patch, only two statements earlier, since the end code
- also does SvCUR_set.

-
-NETaa13413: regmust extractor needed to restart loop on BRANCH for (?:) to work
-From: DESARMENIEN
-Files patched: regcomp.c
- The BRANCH skipper should have restarted the loop from the top.
-
-NETaa13414: the check for accidental list context was done after pm_short check
-From: Michael H. Coen
-Files patched: pp_hot.c
- Moved check for accidental list context to before the pm_short optimization.
-
-NETaa13418: perlre.pod babbled nonsense about | in character classes
-From: Philip Hazel
-Files patched: pod/perlre.pod
- Removed bogus brackets. Now reads:
- Note however that "|" is interpreted as a literal with square brackets,
- so if you write C<[fee|fie|foe]> you're really only matching C<[feio|]>.
-
-NETaa13419: need to document introduction of lexical variables
-From: "Heading, Anthony"
-Files patched: pod/perlfunc.pod
- Now mentions that lexicals aren't introduced till after the current statement.
-
-NETaa13420: formats that overflowed a page caused endless top of forms
-From: Hildo@CONSUL.NL
-Files patched: pp_sys.c
- If a record is too large to fit on a page, it now prints whatever will
- fit and then calls top of form again on the remainder.
-
-NETaa13423: the code to do negative list subscript in scalar context was missing
-From: Steve McDougall
-Files patched: pp.c
- The negative subscript code worked right in list context but not in scalar
- context. In fact, there wasn't code to do it in the scalar context.

-NETaa13432: couldn't call code ref under debugger
-From: Mike Fletcher
-Files patched: op.c pp_hot.c sv.h
- The debugging code assumed it could remember a name to represent a subroutine,
- but anonymous subroutines don't have a name. It now remembers a CV reference
- in that case.
-
-NETaa13435: 1' dumped core
-From: Larry Wall
-Files patched: toke.c
- Didn't check a pointer for nullness.
-
-NETaa13436: print foo(123) didn't treat foo as subroutine
-From: mcook@cognex.com
-Files patched: toke.c
- Now treats it as a subroutine rather than a filehandle.
-
-NETaa13437: &$::foo didn't think $::foo was a variable name
-From: mcook@cognex.com
-Files patched: toke.c
- Now treats $::foo as a global variable.
-
-NETaa13439: referred to old package name
-From: Tom Christiansen
-Files patched: lib/Sys/Syslog.pm
- Wasn't a strict refs problem after all. It was simply referring to package
- syslog, which had been renamed to Sys::Syslog.
-
-NETaa13440: stat operations didn't know what to do with glob or ref to glob
-From: mcook@cognex.com
-Files patched: doio.c pp_sys.c
- Now knows about the kinds of filehandles returned by FileHandle constructors
- and such.
-
-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.
-
-NETaa13443: couldn't override an XSUB
-From: William Setzer
-Files patched: op.c
- When the newSUB and newXS routines checked for whether the old sub was
- defined, they only looked at CvROOT(cv), not CvXSUB(cv).
-
-NETaa13443: needed to do same thing in newXS
-Files patched: op.c
- (same)
-
-NETaa13444: -foo now doesn't warn unless sub foo is defined
-From: Larry Wall
-Files patched: toke.c
- Made it not warn on -foo, unless there is a sub foo defined.
-
-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
- returns one and only one value. If there are fewer, it pushes undef,
- and if there are more, it returns the last one.
-
-NETaa13457: now explicitly disallows printf format with 'n' or '*'.
-From: lees@cps.msu.edu
-Files patched: doop.c
- Now says
-
- Use of n in printf format not supported at ./foo line 3.

- Needed to call SvPOK_only() in pp_substr.
-
-NETaa13459: umask and chmod now warn about missing initial 0 even with paren
-From: Andreas Koenig
-Files patched: toke.c
- Now skips parens as well as whitespace looking for argument.
-
-NETaa13460: backtracking didn't work on .*? because reginput got clobbered
-From: Andreas Koenig
-Files patched: regexec.c
- When .*? did a probe of the rest of the string, it clobbered reginput,
- so the next call to match a . tried to match the newline and failed.
-
-NETaa13475: \(@ary) now treats array as list of scalars
-From: Tim Bunce
-Files patched: op.c
- The mod() routine now refrains from marking @ary as an lvalue if it's in parens
- and is the subject of an OP_REFGEN.

-NETaa13500: needed DESTROY in FileHandle
-From: Tim Bunce
-Files patched: ext/POSIX/POSIX.pm
- Added DESTROY method. Also fixed ungensym to use POSIX:: instead of _POSIX.
- Removed ungensym from close method, since DESTROY should do that now.
-
-NETaa13502: now complains if you use local on a lexical variable
-From: Larry Wall
-Files patched: op.c
- Now says something like
-
- Can't localize lexical variable $var at ./try line 6.

-
-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.

-NETaa13522: substitution couldn't be used on a substr()
-From: Hans Mulder
-Files patched: pp_ctl.c pp_hot.c

-NETaa13553: now warns about 8 or 9 in octal escapes
-From: Mike Rogers
-Files patched: util.c
- Now warns if it finds 8 or 9 before the end of the octal escape sequence.
- So \039 produces a warning, but \0339 does not.
-
-NETaa13554: now allows foreach ${"name"}
-From: Johan Holtman
-Files patched: op.c
- Instead of trying to remove OP_RV2SV, the compiler now just transmutes it into an

-NETaa13589: return was enforcing list context on its arguments
-From: Tim Freeman
-Files patched: opcode.pl
- A return was being treated like a normal list operator, in that it was
- setting list context on its arguments. This was bogus.
-
-NETaa13591: POSIX::creat used wrong argument
-From: Paul Marquess
-Files patched: ext/POSIX/POSIX.pm
- Applied suggested patch.
-
-NETaa13605: use strict refs error message now displays bad ref
-From: Peter Gordon
-Files patched: perl.h pod/perldiag.pod pp.c pp_hot.c
- Now says
-
- Can't use string ("2") as a HASH ref while "strict refs" in use at ./foo line 12.
-
-NETaa13630: eof docs were unclear
-From: Hallvard B Furuseth
-Files patched: pod/perlfunc.pod
- Applied suggested patch.
-
-NETaa13636: $< and $> weren't refetched on undump restart
-From: Steve Pearlmutter
-Files patched: perl.c
- The code in main() bypassed perl_construct on an undump restart, which bypassed
- the code that set $< and $>.
-
-NETaa13641: added Tim's fancy new import whizbangers
-From: Tim Bunce
-Files patched: lib/Exporter.pm
- Applied suggested patch.
-
-NETaa13649: couldn't AUTOLOAD a symbol reference
-From: Larry Wall
-Files patched: pp_hot.c
- pp_entersub needed to guarantee a CV so it would get to the AUTOLOAD code.
-
-NETaa13651: renamed file had wrong package name
-From: Andreas Koenig
-Files patched: lib/File/Path.pm
- Applied suggested patch.
-
-NETaa13660: now that we're testing distribution we can diagnose RANDBITS errors
-From: Karl Glazebrook
-Files patched: t/op/rand.t
- Changed to suggested algorithm. Also duplicated it to test rand(100) too.
-
-NETaa13660: rand.t didn't test for proper distribution within range
-Files patched: t/op/rand.t
- (same)
-
-NETaa13671: array slice misbehaved in a scalar context
-From: Tye McQueen
-Files patched: pp.c
- A spurious else prevented the scalar-context-handling code from running.
-
-NETaa13672: filehandle constructors in POSIX don't return failure successfully
-From: Ian Phillipps
-Files patched: ext/POSIX/POSIX.pm
- Applied suggested patch.
-
-
-NETaa13678: forced $1 to always be untainted
-From: Ka-Ping Yee
-Files patched: mg.c
- I believe the bug that triggered this was fixed elsewhere, but just in case,
- I put in explicit code to force $1 et al not to be tainted regardless.
-
-NETaa13682: formline doc need to discuss ~ and ~~ policy
-From: Peter Gordon
-Files patched: pod/perlfunc.pod
-
-NETaa13686: POSIX::open and POSIX::mkfifo didn't check tainting
-From: Larry Wall
-Files patched: ext/POSIX/POSIX.xs
- open() and mkfifo() now check tainting.
-
-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.
-
-NETaa13687: new Exporter.pm
-Files patched: ext/POSIX/POSIX.pm
- (same)
-
-NETaa13694: add sockaddr_in to Socket.pm
-From: Tim Bunce
-Files patched: ext/Socket/Socket.pm
- Applied suggested patch.

-From: Dean Roehrich
-Files patched: lib/Term/Cap.pm
- Applied suggested patch.
-
-NETaa13710: cryptswitch needed to be more "useable"
-From: Tim Bunce
-Files patched: embed.h global.sym perl.h toke.c
- The cryptswitch_fp function now can operate in two modes. It can
- modify the global rsfp to redirect input as before, or it can modify
- linestr and return true, indicating that it is not necessary for yylex
- to read another line since cryptswitch_fp has just done it.
-
-NETaa13712: new_tmpfile() can't be called as constructor
-From: Hans Mulder
-Files patched: ext/POSIX/POSIX.xs
- Now allows new_tmpfile() to be called as a constructor.
-
-NETaa13714: variable method call not documented
-From: "Randal L. Schwartz"

- Now indicates that OBJECT->$method() works.
-

-Files patched: op.c sv.c
- (same)

--------------
-Version 5.000
--------------
-
-New things
-----------
- The -w switch is much more informative.
-
- 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.
-
- Objects. See t/op/ref.t for examples.
-
- => 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.
-
- 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.
-
- Format value lists may be spread over multiple lines by enclosing in
- 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
- just before exiting.
-
- Flags on the #! line are interpreted even if the script wasn't
- executed directly. (And even if the script was located by "perl -x"!)
-
- The ?: operator is now legal as an lvalue.
-
- List context now propagates to the right side of && and ||, as well
- as the 2nd and 3rd arguments to ?:.
-
- The "defined" function can now take a general expression.
-
- Lexical scoping available via "my". eval can see the current lexical
- variables.
-
- The preferred package delimiter is now :: rather than '.
-
- 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.
-
- 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(),
- 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.
-
- The second and third arguments of splice are now evaluated in scalar
- context (like the book says) rather than list context.
-
- Saying "shift @foo + 20" is now a semantic error because of precedence.
-
- "open FOO || die" is now incorrect. You need parens around the filehandle.
-
- The elements of argument lists for formats are now evaluated in list
- context. This means you can interpolate list values now.
-
- 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, or as a delimiter for any kind of quote construct.
-
- Some error messages will be different.
-
- 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.
-
- m//g now attaches its state to the searched string rather than the
- regular expression.
-
- "reverse" is no longer allowed as the name of a sort subroutine.
-
- 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.
