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: [email protected]
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: [email protected]
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 <[email protected]>
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" <[email protected]>
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: [email protected]
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
From: Andy Dougherty
Files patched: t/TEST
 die "You need to run \"make test\" first to set things up.\n" unless -e 'perl';
 

NETaa13384: fixed version 0.000 botch.
From: Larry Wall
Files patched: installperl

NETaa13385: return 0 from required file loses message
From: Malcolm Beattie
Files patched: pp_ctl.c
 Works right now.

NETaa13387: added pod2latex
From: Taro KAWAGISHI
Files patched: MANIFEST pod/pod2latex
 Added most recent copy to pod directory.

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: Hans Mulder
Files patched: doio.c
 Now treats . and exec as shell metathingies.

NETaa13395: eval didn't check taintedness.
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.

NETaa13400: pod2html update from Bill Middleton
From: Larry Wall
Files patched: pod/pod2html

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
From: Wayne Scott
Files patched: installperl
 Yup, it was missing.

NETaa13406: didn't wipe out dead match when proceeding to next BRANCH
From: Michael P. Clemens
Files patched: regexec.c
 The code to check alternatives didn't invalidate backreferences matched by the
 failed branch.

NETaa13407: overload upgrade
From: [email protected]
Also: Ilya Zakharevich
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.

NETaa13410: delaymagic did =~ instead of &= ~
From: Andreas Schwab
Files patched: pp_hot.c
 Applied supplied patch.

NETaa13411: POSIX didn't compile under -DLEAKTEST
From: Frederic Chauveau
Files patched: ext/POSIX/POSIX.xs
 Used NEWSV instead of newSV.

NETaa13412: new version from Tony Sanders
From: Tony Sanders
Files patched: lib/Term/Cap.pm
 Installed as Term::Cap.pm

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: [email protected]
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.

NETaa13424: existing but undefined CV blocked inheritance
From: Spider Boardman
Files patched: gv.c
 Applied supplied patch.

NETaa13425: removed extra argument to croak
From: "R. Bernstein"
Files patched: regcomp.c
 Removed extra argument.

NETaa13427: added return types
From: "R. Bernstein"
Files patched: x2p/a2py.c
 Applied suggested patch.

NETaa13427: added static declarations
Files patched: x2p/walk.c
 (same)

NETaa13428: split was assuming that all backreferences were defined
From: Dave Schweisguth
Files patched: pp.c
 split was assuming that all backreferences were defined.

NETaa13430: hoistmust wasn't hoisting anchored shortcircuit's length
From: Tom Christiansen
Also: Rob Hooft
Files patched: toke.c

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: [email protected]
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: [email protected]
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: [email protected]
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: [email protected]
Files patched: doop.c
 Now says
 
     Use of n in printf format not supported at ./foo line 3.
 

NETaa13458: needed to call SvPOK_only() in pp_substr
From: Wayne Scott
Files patched: pp.c
 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.

NETaa13481: accept buffer wasn't aligned good enough
From: Holger Bechtold
Also: Christian Murphy
Files patched: pp_sys.c
 Applied suggested patch.

NETaa13486: while (<>) now means while (defined($_ = <>))
From: Jim Balter
Files patched: op.c pod/perlop.pod
 while (<HANDLE>) now means while (defined($_ = <HANDLE>)).

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.

NETaa13512: added $SIG{__WARN__} and $SIG{__DIE__} hooks
From: Larry Wall
Files patched: embed.h gv.c interp.sym mg.c perl.h pod/perlvar.pod pp_ctl.c util.c Todo pod/perldiag.pod

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.

NETaa13520: added closures
From: Larry Wall
Files patched: Todo cv.h embed.h global.sym gv.c interp.sym op.c perl.c perl.h pod/perlform.pod pp.c pp_ctl.c pp_hot.c sv.c sv.h toke.c

NETaa13520: test to see if lexical works in a format now
Files patched: t/op/write.t

NETaa13522: substitution couldn't be used on a substr()
From: Hans Mulder
Files patched: pp_ctl.c pp_hot.c
 Changed pp_subst not to use sv_replace() anymore, which didn't handle lvalues
 and was overkill anyway.  Should be slightly faster this way too.

NETaa13525: G_EVAL mode in perl_call_sv didn't return values right.
Files patched: perl.c

NETaa13525: consolidated error message

From: Tye McQueen
Also: Spider Boardman

NETaa13540: tweak from Charles

NETaa13552: scalar unpack("P4",...) ignored the 4
From: Eric Arnold
Files patched: pp.c
 The optimization that tried to do only one item in a scalar context didn't
 realize that the argument to P was not a repeat count.

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
 OP_RV2GV, which is a no-op for ordinary variables and does the right
 thing for ${"name"}.

NETaa13559: substitution now always checks for readonly
From: Rodger Anderson
Files patched: pp_hot.c
 Substitution now always checks for readonly.

NETaa13561: added explanations of closures and curly-quotes

NETaa13575: documented semantics of negative substr length
From: Jeff Bouis
Files patched: pod/perlfunc.pod
 Documented the fact that negative length now leaves characters off the end,
 and while I was at it, made it work right even if offset wasn't 0.

NETaa13575: negative length to substr didn't work when offset non-zero
Files patched: pp.c
 (same)

NETaa13575: random cleanup

NETaa13580: couldn't localize $ACCUMULATOR
From: Larry Wall
Files patched: gv.c lib/English.pm mg.c perl.c sv.c

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

 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

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"
Files patched: pod/perlobj.pod
 Now indicates that OBJECT->$method() works.

NETaa13715: PACK->$method produces spurious warning
From: Larry Wall
Files patched: toke.c
 The -> operator was telling the lexer to expect an operator when the
 next thing was a variable.

NETaa13716: Carp now allows multiple packages to be skipped out of
From: Larry Wall
Files patched: lib/Carp.pm
 The subroutine redefinition warnings now warn on import collisions.

NETaa13716: Exporter catches warnings and gives a better line number
