------------- 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 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" 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 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: 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: owner-perl5-porters@nicoh.com 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: 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. 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.

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: 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. 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($_ = <>)) From: Jim Balter Files patched: op.c pod/perlop.pod while () now means while (defined($_ = )). 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: Larry Wall Files patched: perl.h toke.c NETaa13525: derived it Files patched: perly.h NETaa13525: missing some values from embed.h Files patched: embed.h NETaa13525: random cleanup Files patched: MANIFEST Todo cop.h lib/TieHash.pm lib/perl5db.pl opcode.h patchlevel.h pod/perldata.pod pod/perlsub.pod t/op/ref.t toke.c NETaa13525: random cleanup Files patched: pp_ctl.c util.c NETaa13527: File::Find needed to export $name and $dir From: Chaim Frenkel Files patched: lib/File/Find.pm They are now exported.

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.

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"}.

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.

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.
