CORE LANGUAGE CHANGES Subject: Bitwise op sign rationalization From: Chip Salzenberg <chip@atlantic.net> Files: op.c opcode.pl pod/perlop.pod pod/perltoc.pod pp.c pp.h pp_hot.c proto.h sv.c t/op/bop.t Make bitwise ops result in unsigned values, unless C<use integer> is in effect. Includes initial support for UVs. Subject: Defined scoping for C<my> in control structures From: Chip Salzenberg <chip@atlantic.net> Files: op.c perly.c perly.c.diff perly.h perly.y proto.h toke.c Finally defines semantics of "my" in control expressions, like the condition of "if" and "while". In all cases, scope of a "my" var extends to the end of the entire control structure. Also adds new construct "for my", which automatically declares the control variable "my" and limits its scope to the loop. Subject: Fix ++/-- after int conversion (e.g. 'printf "%d"') From: Chip Salzenberg <chip@atlantic.net> Files: pp.c pp_hot.c sv.c This patch makes Perl correctly ignore SvIVX() if either NOK or POK is true, since SvIVX() may be a truncated or overflowed version of the real value. Subject: Make code match Camel II re: functions that use $_ From: Paul Marquess <pmarquess@bfsec.bt.co.uk> Files: opcode.pl Subject: Provide scalar context on left side of "->" From: Chip Salzenberg <chip@atlantic.net> Files: perly.c perly.y Subject: Quote bearword package/handle FOO in "funcname FOO => 'bar'" From: Chip Salzenberg <chip@atlantic.net> Files: toke.c OTHER CORE CHANGES Subject: Warn on overflow of octal and hex integers From: Chip Salzenberg <chip@atlantic.net> Files: proto.h toke.c util.c Subject: If -w active, warn for commas and hashes ('#') in qw() From: Chip Salzenberg <chip@atlantic.net> Files: toke.c Subject: Fixes for pack('w') From: Ulrich Pfeifer <pfeifer@charly.informatik.uni-dortmund.de> Files: pp.c t/op/pack.t Subject: More complete output from sv_dump() From: Gurusamy Sarathy <gsar@engin.umich.edu> Files: sv.c Subject: Major '..' and debugger patches From: Ilya Zakharevich <ilya@math.ohio-state.edu> Files: lib/perl5db.pl op.c pp_ctl.c scope.c scope.h Subject: Fix for formline() From: Gurusamy Sarathy <gsar@engin.umich.edu> Files: global.sym mg.c perl.h pod/perldiag.pod pp_ctl.c proto.h sv.c t/op/write.t Subject: Fix stack botch in untie and binmode From: Gurusamy Sarathy <gsar@engin.umich.edu> Files: pp_sys.c Subject: Complete EMBED, including symbols from interp.sym From: Chip Salzenberg <chip@atlantic.net> Files: MANIFEST embed.pl ext/DynaLoader/dlutils.c ext/SDBM_File/sdbm/sdbm.h global.sym handy.h malloc.c perl.h pp_sys.c proto.h regexec.c toke.c util.c x2p/Makefile.SH x2p/a2p.h x2p/handy.h x2p/util.h New define EMBEDMYMALLOC makes embedding total by avoiding "Mymalloc" etc. Subject: Support old embedding for people who want it From: Chip Salzenberg <chip@atlantic.net> Files: MANIFEST Makefile.SH old_embed.pl old_global.sym PORTABILITY Subject: Miscellaneous VMS fixes From: Charles Bailey <bailey@HMIVAX.HUMGEN.UPENN.EDU> Files: lib/ExtUtils/Liblist.pm lib/ExtUtils/MM_VMS.pm lib/Math/Complex.pm lib/Time/Local.pm lib/timelocal.pl perl.h perl_exp.SH proto.h t/TEST t/io/read.t t/lib/findbin.t t/lib/getopt.t util.c utils/h2xs.PL vms/Makefile vms/config.vms vms/descrip.mms vms/ext/Stdio/Stdio.pm vms/ext/Stdio/Stdio.xs vms/perlvms.pod vms/test.com vms/vms.c Subject: DJGPP patches (MS-DOS) From: "Douglas E.
