11Version 5.003_04
12----------------
13
14This patch was primarily to fix bugs and to clean up some of
15the changes made in 5.003_03. The details are described below.
16A very brief summary is:
17
18o Visible Changes to Core Functionality
19
20 -Allow and document permissions for FileHandle::new and
21 IO::File::new.
22 -glob in Safe compartment used to allow shell access; now
23 it's in the same category as `` and system().
24
25o Configure and build enhancements
26
27 -perl library name is again -lperl, not -lperl5 in some cases.
28 -Several hint files no longer set -g -DDEBUGGING by default.
29 Instead, they just turn off optimization, since that is
30 probably what was intended.
31 -Include OS/2 and Plan9 updates.
32
33o Bug fixes
34
35 -SEGV with $_[0] and circular references fixed.
36 -Ilya's debugger patch.
37 -FAKE typeglobs fixed.
38 -truncate with file name now works.
39 -lval substr() no longer coredumps with refs
40 -lval substr now clears lexicals in re-entered scopes.
41 -core dump in caller() for signal handler for __DIE__.
42

143 The /*#define FOO /**/ is a perfectly legal un-nested comment, and

188 Subject: Patch for LONG_MAX & co.
189
190 Sorry about adding yet another #ifdef forest, but hopefully this
191 should resolve the *_MAX issues permanently. It adds to the
192 previously defined PERL_LONG_MAX, PERL_LONG_MIN, and PERL_ULONG_MAX
193 symbols the complete set of
194 /PERL_U?(CHAR|SHORT|INT|LONG)_(MAX|MIN)/, and installs aliases to
195 those from /(I|U)(8|16|32|V)_(MAX|MIN)/ so that for any standard
196 Perl typedef, like I32 or UV, you can reference I32_MAX or UV_MIN,
197 and get appropriate figures. All references to LONG_(MIN|MAX) are
198 changed appropriately.
199
200 The .c changes have the side effect of making cast_uv properly use quad
201 limits if quads are in use, but longs aren't 64 bit. Hopefully this all
202 works, but I don't have any handy Crays to try it out on.
203
204 Add notes on perl's internal types, specifically Quad_t and IV.
205

213 unless that's what the user really wants.

223
224Index: hints/ultrix_4.sh
225
226 Don't call optimize=-g, just call optimize=none. The -g
227 pulls in -DDEBUGGING, which might not be wanted.

244
245 Ilya's debugger patch.
246 Undefined subroutine &Carp::longmess called at
247 /opt/perl5.003_03/lib/perl5db.pl line 1423.
248
249
250 Make perl5db compatible with the recent 'strict refs' enforcement
251 in %SIG.
252
253Index: malloc.c
254
255 A patch to perl5.003_02/malloc to give a sensible error abort() message
256 in ANSI C, and to give it to stderr instead of stdout.
257
258 Use config_h's STRINGIFY macro instead of pre-ANSI "p".
259
260Index: mg.c
261
262 Subject: FAKE typeglobs seriously busted (with patch)
263
264 Handling of fake typeglobs (scalars that are really globs
265 in disguise) is seriously busted since 5.002 (it wasn't
266 so in 5.001n).
267 The problem is that mg_get() on a glob calls gv_efullname()
268 which might coerce its first arg to a string.
269
270 Sub-critical patch to conceivably fix some %SIG problems. (Shared hash key
271 weren't being properly detected by some of the sig magic, but as shared
272 hash keys wouldn't normally be used in %SIG it's unlikely this is a
273 significant problem.)

295 Subject: Re: truncate with file name does not work (with patch)
296
297 The prototype for truncate was changed so that perl won't die
298 with C<use strict;> when the first arg is a bareword (filehandle).
299 I think it was Tom (as in "tchrist") who brought this up.
300

302 C<use strict;>, and adds to the testsuite.

328 Subject: Patch for LONG_MAX & co.
329
330 Sorry about adding yet another #ifdef forest, but hopefully this
331 should resolve the *_MAX issues permanently. It adds to the
332 previously defined PERL_LONG_MAX, PERL_LONG_MIN, and PERL_ULONG_MAX
333 symbols the complete set of

343
344 Add notes on perl's internal types, specifically Quad_t and IV.
345
346Index: perlio.c
347
348 Removes an incorrect prototype for setlinebuf from
349 perlio.c because it conflicts with the correct declaration in
350 MachTen's stdio.h (and possibly other stdio's as well).
351
352 Secondly, the code in perlio.c is not handling the (!PERLIO_IS_STDIO &
353 HAS_F[GS]ETPOS) case. The patch fixes this omission (in a rather lumpen
354 manner). I don't think this should affect platforms which try to hack a
355 different path through the #ifdef forest, but this assertion would benefit
356 from testing...

450 From: Chip Salzenberg <salzench@nielsenmedia.com>
451 Subject: Track SVs for destruction when -DPURIFY
452
453 When checking for memory leaks, I compiled Perl with "-DPURIFY".
454 Although that flag improves the leak checking, it also breaks
455 destruction of global objects, because SVs aren't kept in captive
456 arenas any more.
457
458 This patch rectifies the problem by providing an alternative
459 method for keeping track of SVs when Perl is compiled for Purify.
460 It has no effect on normal operation.
461

463 Add comment about assert(len >=0) when len is unsigned anyway.

543Version 5.003_03
544----------------
545
546Most of the changes in 5.003_03 are to make the build and installation
547process more robust. The details are described below. A very brief
548summary is:
549
550o Visible Changes to Core Functionality
551
552 -Support for tied filehandles.
553
554o Configure enhancements
555
556 -How to build and install a shared libperl.so is now documented
557 and supported, though it's not the default for most platforms.
558
559o Bug fixes
560
561 -Support bit operations on strings longer than 15 bytes.
562
563 -If a regex supplied to split() contains paranthesized subpatterns
564 that can result in null matches, perl no longer coredumps.
565
566 -Fix problems with each() on tied hashes.
567
568 -Make h2ph architecture-independent by using Config at run-time
569 rather than extraction time.

646Index: Configure
647
648 Relaxed warning about ksh on exotic machines.
649
650 Changed usesafe to useopcode.
651
652 Add search for gzip and zip.
653
654 Look more carefully for $sh (the Bourne-ish shell).
655 Use that info to set $startsh correctly.
656
657 Change prompts for PerlIO interface. See INSTALL
658 for how this is supposed to work. The default is
659 still the same as in 5.003_02, namely don't use
660 any fancy new PerlIO stuff.
661
662 Don't look for sigvec() since we don't actually use it.
663 (Plus, it used to print an alarming misleading message about
664 race conditions.)
665
666 Look for stdio's _filbuf under the possible names of
667 _filbuf, __filbuf, and _fill.
668
669 New $useshrplib variable to control whether we build a shared
670 libperl.so. The name of the library is in $libperl.
671 Always install it in $installarchlib/CORE/$libperl.
672
673 Check for <sys/resource.h> and <sys/wait.h> for NetBSD.
674
675 Replace old $altmake stuff with newer autoconf-ish
676 $make_set_make, which checks if $make sets $(MAKE). Now you
677 choose an alternate make with sh Configure -Dmake=gmake (or
678 whatever).
679
680 Remove 'ln' for the list of essential commands. Simulate
681 it with 'cp' if necessary.
682
683 Change `logname` prompts to handle extra gratuitous spaces in
684 Ultrix output.
685
686 Autodetect os2.
687
688 Fix silly bug in checking for fully-qualified names in /etc/hosts.
689
690 Generalize Gconvert tests. Give correct and more useful
691 error messages.
692
693 Use $obj_ext instead of literal '.o' in the dynaloader test.
694
695 Include appropriate header files in bcopy() and memcpy()
696 tests. Note whether memmove is available.
697
698 Check whether struct sigaction works (needed for Solaris 2.5
699 with -Xc).
700
701 Include appropriate header files for randbits test.
702
703Index: INSTALL
704
705 Add note about space requirements.
706
707 Update to match Configure changes (Opcode vs. Safe,
708 useperlio, useshrplib, etc.)
709
710 Reorganize the structure of some of the hints.
711
712 Miscellaneous clarifications.
713
714Index: MANIFEST
715
716 Updated. 5.003_02 introduced some massive patches, mostly
717 due to spacing changes. I didn't bother to sort them all out;
718 I just started with 5.003's MANIEFST.
719
720Index: Makefile.SH
721
722 Support the new simplified shared libperl mechanism.
723
724 Use new $make_set_make directive.
725
726 Remove redundant libperl Make variable.
727
728 Remove unnecessary MAB variable.
729
730 Remove dependency of minitest on lib/Config.pm, since it could
731 well have been a failure of configpm that inspired testing
732 miniperl in the first place!
733
734Index: Porting/Glossary
735
736 New file describing all the config.sh variables.
737 Eventually, I hope to fill this directory with other useful
738 stuff.
739
740Index: README.os2
741
742 Replace old README.os2 with more up-to-date os2/README.
743
744Index: config_H
745
746 Updated to match current Configure and config_h.SH.
747 Some rearrangement of parts has occurred due to new
748 dependencies in the metaconfig units.
749
750Index: config_h.SH
751
752 Updated to match current Configure and config_h.SH.
753 Some rearrangement of parts has occurred due to new
754 dependencies in the metaconfig units.
755
756 Include full descriptions of ARCHLIB, OLDARCHLIB, PRIVLIB,
757 SITEARCH, and SITELIB. Previous versions just included the
758 ~-expanded names (with unhelpful descriptions). No functionality
759 is changed, but maybe it's a little better documented now.
760
761Index: doio.c
762
763 Possibly Include <signal.h> and <unistd.h>
764
765Index: doop.c
766
767 No longer prefer bcmp over memcmp when order doesn't matter.
768
769 Support bit operations on strings longer than 15 bytes.
770
771Index: embed.h
772
773 Auto-generated.
774
775Index: embed.pl

800
801 Typo change.
802 Get rid of unused altmake.
803
804Index: global.sym
805
806 Fix problems with each() on tied hashes.
807
808Index: handy.h
809
810 Change safe*alloc functions to have prototypes that
811 match the system's malloc and free types. That is, use
812 Malloc_t instead of char *, and Free_t instead of void.
813 This is necessary so . . .
814
815 Safefree cast matches type of free() whether it's perl's
816 malloc/free or the system's malloc/free.
817
818Index: hints/README.hints
819
820 Remove out-of-date info.
821
822 Document a bit about how hint files work.
823
824Index: hints/aix.sh
825
826 qmaxmem hint doesn't apply to gcc.
827
828Index: hints/dgux.sh
829
830 Configure will now automatically detect shared libperl stuff.
831
832Index: hints/dynixptx.sh
833
834 Fix typo in comment.
835
836 Configure will now automatically detect shared libperl stuff.
837
838Index: hints/epix.sh
839
840 Use glibpth instead of libpth. This allows Configure to
841 add local directories, such as /opt/local/lib, etc.
842
843Index: hints/irix_6_2.sh
844
845 Include some info on cc -n32 compile.
846

848
849 Configure now tests gcvt() more thoroughly.
850
851Index: hints/machten_2.sh
852
853 Update where to find dld.
854
855Index: hints/mips.sh
856
857 Use glibpth instead of libpth.
858
859Index: hints/next_3.sh
860
861 Build up $mab dynamically. Since $mab isn't used anywhere
862 anymore, this is useless. However, $mab was never used for
863 next_3.sh anyway, so there's been no change in functionality.
864
865Index: hints/next_4.sh
866
867 Get rid of extraneous isnext_4 variable. Configure and
868 Makefile.SH will use $osname and $osvers instead.
869
870 Build up $mab dynamically based on available architectures.
871
872 Absorb $mab into ccflags and ccdlflags. I hope that will
873 cover everything. (Configure should automatically remove
874 the -arch stuff from cppflags.)
875
876 Configure now knows next4 needs to use a shared libperl.5.so.
877
878 Allow users to use -Dprefix.
879
880Index: hints/os2.sh
881
882 Try to update to reflect newer shared libperl stuff.
883 I probably goofed :-).
884

886
887 Additional notes on using icc.
888
889 Additional flags for dynamic loading.
890
891Index: hints/solaris_2.sh
892
893 Perl.h no longer prefers bcmp, so it's again ok if Configure
894 finds them, since perl will prefer the mem* versions anyway.
895
896Index: hints/sunos_4_0.sh
897
898 Don't include <unistd.h>

950 Put back in the BEGIN { require 5.002; }. The version in
951 5.003_02 wouldn't work in 5.002 anyway. Further, the whole
952 point of the construct is to catch 5.001m, so we can't use
953 syntax introduced after 5.001m to do that.
954
955Index: lib/Text/Wrap.pm
956

972
973 Include <unistd.h>
974
975 Use Safefree() macro instead of safefree() function with
976 a (possibly) incorrect cast. The whole point of the
977 Safefree() macro is that it does the correct cast for you.

991 about ordering.
992
993 Rely on Configure setting SH_PATH.
994
995 Change the function name to Pause() instead of pause() to
996 avoid potential prototype problems. (This naming convention
997 is similar to the Fwrite and Fflush macros.)
998
999 Fix problems with each() on tied hashes.

1013 but I'm not going to redo the patch just to put back in the trailing
1014 whitespace either.)

1160Version 5.003_02
1161----------------
1162o Visible Changes to Core Functionality
1163 - Redefining constant subs, or changing sub's prototype now give warnings.
1164 - Fixes for ++/-- of values close to max/min size of an integer
1165 - Warning for un-qualified bareword as handler in $SIG{}.
1166 - UNIVERSAL::isa can now be called as static method.
1167
1168o Changes in Core Internals
1169 - PerlIO abstraction added.
1170 Perl core and standard extensions no longer assume ANSI C's stdio is IO
1171 mechanism, Default Configure mode is still to use stdio via set of C macros.
1172 Alternate modes are to use stdio via one perlio.c module, or
1173 to use sfio if available.
1174
1175 - Several bug fixs from perl5-porters
1176 - Make sources non-ANSI C correct again.
1177 - SUPER in gv.c
1178 - Last of shared-hash-key patches
1179 - eval '(0,1..3)'; # --> SegFault
1180 - coredumps after simple subsitutes.
1181 - Correction to UNIVERSAL::VERSION docs.
1182 - Fixed io_udp test.
1183 - Fixed another abuse of malloc'ed memory.
1184 - Enabled DEBUGING_MSTATS whenever perl's malloc() is used.
1185 - Reverted to default of not hiding perl's malloc (if used).
1186
1187o Changes in the Standard Library and Utilities
1188 - Fixed MakeMaker for static SDBM and builing in a link tree.
1189 - Upgraded to IO-1.09, and includes latest (still experimental) IO::Select.
1190 - Documentation/test tweak to DB_File
1191 - h2xs upgrade to allow use C::Scan module
1192
1193o Changes in OS-specific and Build-time Support
1194 - Attempted to re-created 5.003_01's NeXT support with metaconfig units.
1195 - Updated MANIFEST
1196 - make minitest now depends on lib/Config.pm, as some of tests require it.
1197 - Included latest plan9 sub-directory
1198 - Applied OS/2 patches.
1199 - Typo patch for VMS.

1202Version 5.003_01
1203----------------
1204
1205Version 5.003_01 contains bugfixes and additions accumulated since
1206version 5.002_01, since the patch to version 5.003 was deliberately
1207kept simple. In addition to numerous small bugfixes in the core,
1208library files, and documentation, this patch contains several
1209significant revisions, summarized below:
1210
1211o Visible Changes to Core Functionality
1212
1213 - A port to Plan9 has been started, and changes are integrated into
1214 the standard distribution. As of this release, the Perl core
1215 and several common extensions are working.
1216
1217 - A set of basic methods in the UNIVERSAL class have been added to
1218 the Perl core. Since UNIVERSAL is an implicit member of every
1219 class's @ISA, the methods can be called via any object.
1220
1221 - A mandatory warning has been added for 'declarations' of lexical
1222 variables using the "my" operator which mask an existing lexical
1223 variable declared in the same scope, making the previous variable
1224 inaccessible by its name.
1225
1226 - The "use" and "require" operators have been extended to allow
1227 checking of the required module's version. The "use" operator
1228 can now be used for an immediate version check of Perl itself.
1229
1230 - A new "strict" pragma, "strict untie", has been added, which
1231 produces an error if a tied value is untied when other references
1232 exist to the internal object implementing the tie.
1233
1234 - Barewords used as associative array keys (i.e. when specifying
1235 an associative array element like $foo{__BAR} or on the left
1236 side of the => operator) may now begin with an underscore as
1237 well as an alphabetic character.
1238
1239 - Some of the configuration information previously produced by the
1240 -v switch has been moved to the -V switch, in order to keep -v
1241 output concise.
1242
1243o Changes in Core Internals
1244
1245 - Symbol table and method lookups have been made faster.
1246
1247 - Perl subroutines which just return a constant value are now
1248 optimized at compile time into inline constants.
1249
1250 - Management of keys for associative arrays has been improved to
1251 conserve space when the same keys are reused frequently, and
1252 to pass true Perl values to tie functions, instead of stringified
1253 representations.
1254
1255 - Messages normally output to stderr may be directed to another
1256 stream when Perl is built. This allows some platforms to
1257 present diagnostic output in a separate window from normal
1258 program results.
1259
1260 - A bug which caused suiperl to fail silently, albeit securely,
1261 in version 5.003 on some systems has been fixed.
1262
1263 - Management of Unix-style signal handlers via the %SIG associative
1264 array has been made safer.
1265
1266 - Several global C symbols have been renamed to eliminate collisions
1267 with system C header files or libraries on some platforms.
1268 Unfortunately, this means that dynamic extensions compiled under
1269 previous versions of Perl will need to be rebuilt for Perl
1270 5.003_01. We're in the process of cleaning up Perl's C
1271 namespace to make it easier to link Perl with other binaries,
1272 so this will probably happen again between now and version 5.004.
1273 After that, we'll do our best to maintain binary compatibility
1274 between versions.
1275
1276 - An alternate allocation strategy has been added to Perl's
1277 optional private memory management routines. This strategy,
1278 which may be selected when Perl is built, is designed to
1279 conserve memory in programs which allocate many small
1280 chunks of memory with sizes near a power of 2, as is often
1281 the case in Perl programs.
1282
1283 - Several memory leaks in the creation and destruction of
1284 multiple interpreters have been fixed.
1285
1286o Changes in the Standard Library and Utilities
1287
1288 - The Opcode extension, which allows you to control a program's
1289 access to Perl operations, has been added to the standard
1290 distribution. This extends the work begun in the original
1291 Safe extension, and subsumes it. The Safe interface is still
1292 available.
1293
1294 - The IO extension, which provides a set of classes for object-
1295 oriented handling of common I/O tasks, has been added to the
1296 standard distribution. The IO classes will form the basis
1297 for future development of Perl's I/O interface, and will
1298 subsume the FileHandle class in the near future. The default
1299 class to which all Perl I/O handles belong is now IO::Handle,
1300 rather than FileHandle.
1301
1302 - The ExtUtils::Embed library module, which provides a set
1303 of utility function to help in embedding Perl in other
1304 applications, has been added to the standard distribution.
1305
1306 - The Fatal library module, which provides a simple interface
1307 for creating "do-or-die" equivalents of existing functions,
1308 has been added to the standard distribution.
1309
1310 - The FindBin library module, which determines the full path
1311 to the currently executing program, has been added to the
1312 standard distribution.
1313
1314 - The DB_File extension, and the Getopt::Long, Test::Harness,
1315 Text::Tabs, Text::Wrap, Time::Local and sigtrap library modules
1316 have been updated to the authors' latest versions.
1317
1318 - The Carp library module now considers the @ISA chain when
1319 determining the caller's package for inclusion in error messages.
1320
1321 - The h2xs, perlbug, and xsubpp utilities have been updated.
1322
1323 - The standard Perl debugger has been updated, and the information
1324 provided to the debugger when an XSUB is called has been improved,
1325 making it possible for alternate debuggers (such as Devel::DProf)
1326 to do a better job of tracking XSUB calls.
1327
1328 - The pod documentation formatting tools in the standard distribution
1329 can now handle characters in the input stream whose high bit is set.
1330
1331 - The cperl-mode EMACS editing mode has been updated.
1332
1333o Changes in Documentation
1334
1335 - Typographic and formatting errors have been corrected in the pod
1336 documentation for the core and standard library files
1337
1338 - Explanations of several core operators have been improved
1339
1340 - The perldebug, perlembed, perlipc, perlsec, and perltrap documents
1341 extensively revised.
1342
1343o Changes in OS-specific and Build-time Support
1344
1345 - Support for the NeXT platform has been extended through
1346 NeXTSTEP/OPENSTEP 4.0, and now includes the ability to create MABs.
1347
1348 - Support for OS/2 has been extended as well, and now includes
1349 options for building a.out binaries.
1350
1351 - Support for VMS has also been extended, incorporating improved
1352 processing of file specification strings, optional suppression of
1353 carriage control interpretation for record-structured files,
1354 improved support for the -S command line switch, a number of
1355 VMS-specific bugfixes, and significantly improved performance
1356 in line-oriented reading of files.
1357
1358 - Several hints files have been added or updated: aux.sh (updated),
1359 convexos.sh (updated), irix_4.sh (updated), irix_5.sh (updated),
1360 irix_6_2.sh (updated), next_3.sh (updated), next_3_2.sh (new),
1361 next_3_3.sh (new), next_4.sh (new), os2/sh (updated),
1362 sco.sh (updated), and solaris_2.sh (updated).
1363
1364 - The test driver for the regression tests now reports when a set
1365 of tests have been skipped (presumable because the operation
1366 they're designed to test isn't supported on the current system).
