-New things
-----------
- The -w switch is much more informative.
+Please note: This file provides a summary of significant changes
+between versions and sub-versions of Perl, not necessarily a complete
+list of each modification. If you'd like more detailed information,
+please consult the comments in the patches on which the relevant
+release of Perl is based. (Patches can be found on any CPAN
+site, in the .../src/5.0 directory for full version releases,
+or in the .../src/5/0/unsupported directory for sub-version
+releases.)
- References. See t/op/ref.t for examples. All entities in Perl 5 are
- reference counted so that it knows when each item should be destroyed.
+----------------
+Version 5.003_05
+----------------
- Objects. See t/op/ref.t for examples.
+This patch was primarily to fix bugs and to clean up some of
+the remaining issues from in 5.003_04. The details are described below.
+A very brief summary is:
- => is now a synonym for comma. This is useful as documentation for
- arguments that come in pairs, such as initializers for associative arrays,
- or named arguments to a subroutine.
+o Visible Changes to Core Functionality
- All functions have been turned into list operators or unary operators,
- meaning the parens are optional. Even subroutines may be called as
- list operators if they've already been declared.
+ -Add support for a READLINE method to tied filehandles.
+
+ -times function now uses CLK_TCK if HZ is not available, rather
+ than just defaulting to 60. times output might change on some
+ systems, but should be correct now.
- More embeddible. See main.c and embed_h.sh. Multiple interpreters
- in the same process are supported (though not with interleaved
- execution yet).
+ -AnyDBM_File (modifying ISA does not work as expected)
+ Now behaves as documented: Modifying ISA works to select
+ order in which *DB* modules are tried. The default is still
+ the same.
- The interpreter is now flattened out. Compare Perl 4's eval.c with
- the perl 5's pp.c. Compare Perl 4's 900 line interpreter loop in cmd.c
- with Perl 5's 1 line interpreter loop in run.c. Eventually we'll make
- everything non-blocking so we can interface nicely with a scheduler.
+o Configure and build enhancements
- eval is now treated more like a subroutine call. Among other things,
- this means you can return from it.
+ -Enhance detection of [gs]etpgrp() variants. Some systems have
+ BSD-style behavior for one and POSIX for the other. Use
+ [gs]etpgid() instead, whenever possible.
+
+ -You can now build a shared libperl.so without running through
+ the LD_RUN_PATH hoops, if your system supports appropriate
+ ld command-line options. Solaris, NetBSD, and Linux are currently
+ supported. Others are easy to add. (This makes like a lot easier
+ for embedders.)
- Format value lists may be spread over multiple lines by enclosing in
- a do {} block.
+ -VMS updates.
+
+ -Fix installperl and installman so that the -n option really only
+ prints commands. (previously, it would still do the mkdirs.)
- You may now define BEGIN and END subroutines for each package. The BEGIN
- subroutine executes the moment it's parsed. The END subroutine executes
- just before exiting.
+o Bug fixes
- Flags on the #! line are interpreted even if the script wasn't
- executed directly. (And even if the script was located by "perl -x"!)
+ -debugger ought to work.
- The ?: operator is now legal as an lvalue.
+ -A new heredoc tag in Makefile.SH is now quoted. This prevented
+ 5.003_04 from working most places.
- List context now propagates to the right side of && and ||, as well
- as the 2nd and 3rd arguments to ?:.
+ -numerous smaller ones, detailed below.
- The "defined" function can now take a general expression.
+o Specific Changes
- Lexical scoping available via "my". eval can see the current lexical
- variables.
+Here are the specific file-by-file changes.
- The preferred package delimiter is now :: rather than '.
+# This is my patch perl5.003_05.pat to perl5.003_04
+# The full description is below.
+# Please execute the following commands before applying this patch.
+# (You can feed this patch to 'sh' to do so.)
+# Andy Dougherty <doughera@lafcol.lafayette.edu>
- tie/untie are now preferred to dbmopen/dbmclose. Multiple DBM
- implementations are allowed in the same executable, so you can
- write scripts to interchange data among different formats.
+# We'll create a new test, but patch won't automatically make it
+# executable.
+touch t/io/read.t
+chmod +x t/io/read.t
- New "and" and "or" operators work just like && and || but with
- a precedence lower than comma, so they work better with list operators.
+exit 0
- New functions include: abs(), chr(), uc(), ucfirst(), lc(), lcfirst(),
- chomp(), glob()
- require with a number checks to see that the version of Perl that is
- currently running is at least that number.
+This is patch perl5.003_05.pat to perl version 5.003_04.
+This takes you from 5.003_04 to 5.003_05.
- Dynamic loading of external modules is now supported.
+To apply this patch, run the above commands,
+cd to your perl source directory and then type
- There is a new quote form qw//, which is equivalent to split(' ', q//).
+ patch -p1 -N < perl5.003_05.pat
- Assignment of a reference to a glob value now just replaces the
- single element of the glob corresponding to the reference type:
- *foo = \$bar, *foo = \&bletch;
+The changes are described after each /^Index/ line below. This is
+designed so you can examine each change with a command such as
- Filehandle methods are now supported:
- output_autoflush STDOUT 1;
+ csplit -k perl5.003_05.pat '/^Index:/' '{99}'
- There is now an "English" module that provides human readable translations
- for cryptic variable names.
+Patch and enjoy,
- Autoload stubs can now call the replacement subroutine with goto &realsub.
+ Andy Dougherty doughera@lafcol.lafayette.edu

- Subroutines can be defined lazily in any package by declaring an AUTOLOAD
- routine, which will be called if a non-existent subroutine is called in
- that package.
+Index: Changes
- Several previously added features have been subsumed under the new
- keywords "use" and "no". Saying "use Module LIST" is short for
- BEGIN { require Module; import Module LIST; }
- The "no" keyword is identical except that it calls "unimport" instead.
- The earlier pragma mechanism now uses this mechanism, and two new
- modules have been added to the library to implement "use integer"
- and variations of "use strict vars, refs, subs".
+ Updated for 5.003_05.
- Variables may now be interpolated literally into a pattern by prefixing
- them with \Q, which works just like \U, but backwhacks non-alphanumerics
- instead. There is also a corresponding quotemeta function.
+Index: Configure
- Any quantifier in a regular expression may now be followed by a ? to
- indicate that the pattern is supposed to match as little as possible.
+ Allow command line or hint-file overrides of $afs.
- Pattern matches may now be followed by an m or s modifier to explicitly
- request multiline or singleline semantics. An s modifier makes . match
- newline.
+ Allow trailing spaces in nm output for HPUX10.
- Patterns may now contain \A to match only at the beginning of the string,
- and \Z to match only at the end. These differ from ^ and $ in that
- they ignore multiline semantics. In addition, \G matches where the
- last interation of m//g or s///g left off.
+ Check for newer BIND 'search' directives in /etc/resolv.conf as well
+ as older 'domain' directive.
- Non-backreference-producing parens of various sorts may now be
- indicated by placing a ? directly after the opening parenthesis,
- followed by a character that indicates the purpose of the parens.
- An :, for instance, indicates simple grouping. (?:a|b|c) will
- match any of a, b or c without producing a backreference. It does
- "eat" the input. There are also assertions which do not eat the
- input but do lookahead for you. (?=stuff) indicates that the next
- thing must be "stuff". (?!nonsense) indicates that the next thing
- must not be "nonsense".
+ Enhance detection of [gs]etpgrp() variants. Some systems have
+ BSD-style behavior for one and POSIX for the other. Use
+ [gs]etpgid() instead, whenever possible.
- The negation operator now treats non-numeric strings specially.
- A -"text" is turned into "-text", so that -bareword is the same
- as "-bareword". If the string already begins with a + or -, it
- is flipped to the other sign.
+ Include -s in the -h summary of available options.
-Incompatibilities
------------------
- @ now always interpolates an array in double-quotish strings. Some programs
- may now need to use backslash to protect any @ that shouldn't interpolate.
+ Allow command-line override of $afs.
- Ordinary variables starting with underscore are no longer forced into
- package main.
+ Handle trailing spaces in nm-output on HPUX10.
- s'$lhs'$rhs' now does no interpolation on either side. It used to
- interplolate $lhs but not $rhs.
+ Set shrpenv for handling LD_RUN_PATH, if needed. (This used to
+ be in Makefile.SH. Now it's available for other modules too.)
- The second and third arguments of splice are now evaluated in scalar
- context (like the book says) rather than list context.
+ When using shared libperl, avoid LD_RUN_PATH if possible by adding
+ correct ld flags. Currently, Solaris and NetBSD get the correct
+ -R $archlibexp/CORE, and Linux gets its
+ -Wl,-rpath,$archlibexp/CORE flag. Other contributions are
+ welcome.
- Saying "shift @foo + 20" is now a semantic error because of precedence.
+Index: INSTALL
- "open FOO || die" is now incorrect. You need parens around the filehandle.
+ Correct libperl5 -> libperl typo.
- The elements of argument lists for formats are now evaluated in list
- context. This means you can interpolate list values now.
+ Describe MakeMaker's Warning (will try anyway) messages.
- You can't do a goto into a block that is optimized away. Darn.
+ More info on where and how to send reports.
- It is no longer syntactically legal to use whitespace as the name
- of a variable, or as a delimiter for any kind of quote construct.
+ Add info on non-Unix ports.
- Some error messages will be different.
- The caller function now returns a false value in a scalar context if there
- is no caller. This lets library files determine if they're being required.
+Index: MANIFEST
- m//g now attaches its state to the searched string rather than the
- regular expression.
+ Add new test t/io/read.t.
- "reverse" is no longer allowed as the name of a sort subroutine.
+ Add new hints files for ODBM_File for ultrix and hpux.
- taintperl is no longer a separate executable. There is now a -T
- switch to turn on tainting when it isn't turned on automatically.
+ Add new pod checker script.
- Symbols starting with _ are no longer forced into package main, except
- for $_ itself (and @_, etc.).
+Index: Makefile.SH
- Double-quoted strings may no longer end with an unescaped $ or @.
+ A new heredoc tag in Makefile.SH needs to be quoted.
- Negative array subscripts now count from the end of the array.
+ shrpenv stuff moved to Configure.
- The comma operator in a scalar context is now guaranteed to give a
- scalar context to its arguments.
+Index: Porting/Glossary
- The ** operator now binds more tightly than unary minus.
+ Updated to match Configure.
- Setting $#array lower now discards array elements so that destructors
- work reasonably.
+Index: README.vms
- delete is not guaranteed to return the old value for tied arrays,
- since this capability may be onerous for some modules to implement.
+ VMS 5.003_05 Update.
- Attempts to set $1 through $9 now result in a run-time error.

+ Subject: Perl 5.003.03: race condition in t/lib/io_sock.t
+
+ io_sock.t works by forking a subprocess it can communicate with.
+ It has the subprocess wait for the main process by sleeping 10
+ seconds or until an alarm arrives.
+
+ With my setup, the alarm signal arrives *before* the child
+ has a chance to ignore the alarm signal.
+

+ Subject: updated h2xs
+
+ Changes:
+ a) Docs and examples for -x updated;
+ b) Path to xxxx.h would not be changed to /usr/include/xxxx.h
+ unless this file exists (outside of VMS, I'm afraid to make an error
+ there). - Useful with -x option, when the file may be eaten via -I
+ inside -F.
+ c) .h file would be scanned only if needed.
+ d) typemap would be generated (with T_PTROBJ).
+ e) Documentation (=list) for autogenerated guys would be
+ included into POD.
+ f) duplicated XSUBs would not be generated;
+ g) arguments to XSUBs being arrays are recognized (note that
+ xsubpp would probably choke on such guys).
+
+ -x option requires C-Scan-0.3 (releases a couple of minutes ago to

+----------------
+Version 5.003_04
+----------------
+
+This patch was primarily to fix bugs and to clean up some of
+the changes made in 5.003_03. The details are described below.
+A very brief summary is:
+
+o Visible Changes to Core Functionality
+
+ -Allow and document permissions for FileHandle::new and
+ IO::File::new.
+ -glob in Safe compartment used to allow shell access; now
+ it's in the same category as `` and system().
+
+o Configure and build enhancements
+
+ -perl library name is again -lperl, not -lperl5 in some cases.
+ -Several hint files no longer set -g -DDEBUGGING by default.
+ Instead, they just turn off optimization, since that is
+ probably what was intended.
+ -Include OS/2 and Plan9 updates.
+
+o Bug fixes
+
+ -SEGV with $_[0] and circular references fixed.
+ -Ilya's debugger patch.
+ -FAKE typeglobs fixed.
+ -truncate with file name now works.
+ -lval substr() no longer coredumps with refs
+ -lval substr now clears lexicals in re-entered scopes.
+ -core dump in caller() for signal handler for __DIE__.
+
+o Specific Changes
+
+Here are the specific file-by-file changes.

+
+ Subject: Patch for LONG_MAX & co.
+
+ Sorry about adding yet another #ifdef forest, but hopefully this

+ symbols the complete set of
+ /PERL_U?(CHAR|SHORT|INT|LONG)_(MAX|MIN)/, and installs aliases to
+ those from /(I|U)(8|16|32|V)_(MAX|MIN)/ so that for any standard
+ Perl typedef, like I32 or UV, you can reference I32_MAX or UV_MIN,
+ and get appropriate figures. All references to LONG_(MIN|MAX) are
+ changed appropriately.
+
+ The .c changes have the side effect of making cast_uv properly use quad
+ limits if quads are in use, but longs aren't 64 bit. Hopefully this all
+ works, but I don't have any handy Crays to try it out on.
+

+
+ Make perl5db compatible with the recent 'strict refs' enforcement
+ in %SIG.
+
+Index: malloc.c
+
+ A patch to perl5.003_02/malloc to give a sensible error abort() message
+ in ANSI C, and to give it to stderr instead of stdout.
+
+ Use config_h's STRINGIFY macro instead of pre-ANSI "p".
+
+Index: mg.c
+
+ Subject: FAKE typeglobs seriously busted (with patch)
+
+ Handling of fake typeglobs (scalars that are really globs
+ in disguise) is seriously busted since 5.002 (it wasn't
+ so in 5.001n).
+ The problem is that mg_get() on a glob calls gv_efullname()
+ which might coerce its first arg to a string.
+
+ Sub-critical patch to conceivably fix some %SIG problems. (Shared hash key
+ weren't being properly detected by some of the sig magic, but as shared
+ hash keys wouldn't normally be used in %SIG it's unlikely this is a
+ significant problem.)
+
+ This patch changes neither behavior nor performance. However, it does
+ reduce code size and improve maintainability by combining some common
+ code in gv_fullname() and gv_efullname().
+
+Index: myconfig

+
+ Subject: Re: truncate with file name does not work (with patch)
+
+ The prototype for truncate was changed so that perl won't die
+ with C<use strict;> when the first arg is a bareword (filehandle).
+ I think it was Tom (as in "tchrist") who brought this up.
+
+ Here's a patch that undoes the damage, makes it work with
+ C<use strict;>, and adds to the testsuite.

+
+Index: perlio.c
+
+ Removes an incorrect prototype for setlinebuf from
+ perlio.c because it conflicts with the correct declaration in
+ MachTen's stdio.h (and possibly other stdio's as well).
+
+ Secondly, the code in perlio.c is not handling the (!PERLIO_IS_STDIO &
+ HAS_F[GS]ETPOS) case. The patch fixes this omission (in a rather lumpen
+ manner). I don't think this should affect platforms which try to hack a
+ different path through the #ifdef forest, but this assertion would benefit
+ from testing...

+ Subject: Track SVs for destruction when -DPURIFY
+
+ When checking for memory leaks, I compiled Perl with "-DPURIFY".
+ Although that flag improves the leak checking, it also breaks
+ destruction of global objects, because SVs aren't kept in captive
+ arenas any more.
+
+ This patch rectifies the problem by providing an alternative
+ method for keeping track of SVs when Perl is compiled for Purify.

+----------------
+
+Most of the changes in 5.003_03 are to make the build and installation

+ -Support for tied filehandles.
+
+o Configure enhancements

+ -How to build and install a shared libperl.so is now documented

+o Bug fixes
+
+ -Support bit operations on strings longer than 15 bytes.
+
+ -If a regex supplied to split() contains paranthesized subpatterns

+
+ -Fix problems with each() on tied hashes.
+
+ -Make h2ph architecture-independent by using Config at run-time

+ error messages.
+
+ Use $obj_ext instead of literal '.o' in the dynaloader test.
+
+ Include appropriate header files in bcopy() and memcpy()
+ tests. Note whether memmove is available.
+
+ Check whether struct sigaction works (needed for Solaris 2.5
+ with -Xc).
+
+ Include appropriate header files for randbits test.

+----------------
+Version 5.003_02
+----------------
+o Visible Changes to Core Functionality
+ - Redefining constant subs, or changing sub's prototype now give warnings.

+ to use sfio if available.
+
+ - Several bug fixs from perl5-porters
+ - Make sources non-ANSI C correct again.

+ - Fixed io_udp test.
+ - Fixed another abuse of malloc'ed memory.
+ - Enabled DEBUGING_MSTATS whenever perl's malloc() is used.
+ - Reverted to default of not hiding perl's malloc (if used).
+
+o Changes in the Standard Library and Utilities
+ - Fixed MakeMaker for static SDBM and builing in a link tree.
+ - Upgraded to IO-1.09, and includes latest (still experimental) IO::Select.
+ - Documentation/test tweak to DB_File
+ - h2xs upgrade to allow use C::Scan module
+
+o Changes in OS-specific and Build-time Support
+ - Attempted to re-created 5.003_01's NeXT support with metaconfig units.

+ - Applied OS/2 patches.
+ - Typo patch for VMS.
+
+----------------
+Version 5.003_01
+----------------
+
+Version 5.003_01 contains bugfixes and additions accumulated since
+version 5.002_01, since the patch to version 5.003 was deliberately
+kept simple. In addition to numerous small bugfixes in the core,
+library files, and documentation, this patch contains several
+significant revisions, summarized below:
+
+o Visible Changes to Core Functionality
+
+ - A port to Plan9 has been started, and changes are integrated into
+ the standard distribution. As of this release, the Perl core
+ and several common extensions are working.
+
+ - A set of basic methods in the UNIVERSAL class have been added to
+ the Perl core. Since UNIVERSAL is an implicit member of every
+ class's @ISA, the methods can be called via any object.
+
+ - A mandatory warning has been added for 'declarations' of lexical
+ variables using the "my" operator which mask an existing lexical
+ variable declared in the same scope, making the previous variable
+ inaccessible by its name.
+
+ - The "use" and "require" operators have been extended to allow
+ checking of the required module's version. The "use" operator
+ can now be used for an immediate version check of Perl itself.
+
+ - A new "strict" pragma, "strict untie", has been added, which
+ produces an error if a tied value is untied when other references
+ exist to the internal object implementing the tie.
+
+ - Barewords used as associative array keys (i.e. when specifying
+ an associative array element like $foo{__BAR} or on the left
+ side of the => operator) may now begin with an underscore as
+ well as an alphabetic character.
+
+ - Some of the configuration information previously produced by the
+ -v switch has been moved to the -V switch, in order to keep -v
+ output concise.
+
+o Changes in Core Internals
+
+ - Symbol table and method lookups have been made faster.
+
+ - Perl subroutines which just return a constant value are now
+ optimized at compile time into inline constants.
+
+ - Management of keys for associative arrays has been improved to
+ conserve space when the same keys are reused frequently, and
+ to pass true Perl values to tie functions, instead of stringified
+ representations.
+
+ - Messages normally output to stderr may be directed to another
+ stream when Perl is built. This allows some platforms to
+ present diagnostic output in a separate window from normal
+ program results.
+
+ - A bug which caused suiperl to fail silently, albeit securely,
+ in version 5.003 on some systems has been fixed.
+
+ - Management of Unix-style signal handlers via the %SIG associative
+ array has been made safer.
+
+ - Several global C symbols have been renamed to eliminate collisions
+ with system C header files or libraries on some platforms.
+ Unfortunately, this means that dynamic extensions compiled under
+ previous versions of Perl will need to be rebuilt for Perl
+ 5.003_01. We're in the process of cleaning up Perl's C
+ namespace to make it easier to link Perl with other binaries,
+ so this will probably happen again between now and version 5.004.
+ After that, we'll do our best to maintain binary compatibility
+ between versions.
+
+ - An alternate allocation strategy has been added to Perl's
+ optional private memory management routines. This strategy,
+ which may be selected when Perl is built, is designed to
+ conserve memory in programs which allocate many small
+ chunks of memory with sizes near a power of 2, as is often
+ the case in Perl programs.
+
+ - Several memory leaks in the creation and destruction of
+ multiple interpreters have been fixed.
+
+o Changes in the Standard Library and Utilities
+
+ - The Opcode extension, which allows you to control a program's
+ access to Perl operations, has been added to the standard
+ distribution. This extends the work begun in the original
+ Safe extension, and subsumes it. The Safe interface is still
+ available.
+
+ - The IO extension, which provides a set of classes for object-
+ oriented handling of common I/O tasks, has been added to the
+ standard distribution. The IO classes will form the basis
+ for future development of Perl's I/O interface, and will
+ subsume the FileHandle class in the near future. The default
+ class to which all Perl I/O handles belong is now IO::Handle,
+ rather than FileHandle.
+
+ - The ExtUtils::Embed library module, which provides a set
+ of utility function to help in embedding Perl in other
+ applications, has been added to the standard distribution.
+
+ - The Fatal library module, which provides a simple interface
+ for creating "do-or-die" equivalents of existing functions,
+ has been added to the standard distribution.
+
+ - The FindBin library module, which determines the full path
+ to the currently executing program, has been added to the
+ standard distribution.
+
+ - The DB_File extension, and the Getopt::Long, Test::Harness,
+ Text::Tabs, Text::Wrap, Time::Local and sigtrap library modules
+ have been updated to the authors' latest versions.
+
+ - The Carp library module now considers the @ISA chain when
+ determining the caller's package for inclusion in error messages.
+
+ - The h2xs, perlbug, and xsubpp utilities have been updated.
+
+ - The standard Perl debugger has been updated, and the information
+ provided to the debugger when an XSUB is called has been improved,
+ making it possible for alternate debuggers (such as Devel::DProf)
+ to do a better job of tracking XSUB calls.
+
+ - The pod documentation formatting tools in the standard distribution
+ can now handle characters in the input stream whose high bit is set.
+
+ - The cperl-mode EMACS editing mode has been updated.
+
+o Changes in Documentation
+
+ - Typographic and formatting errors have been corrected in the pod
+ documentation for the core and standard library files
+
+ - Explanations of several core operators have been improved
+
+ - The perldebug, perlembed, perlipc, perlsec, and perltrap documents
+ extensively revised.
+
+o Changes in OS-specific and Build-time Support
+
+ - Support for the NeXT platform has been extended through
+ NeXTSTEP/OPENSTEP 4.0, and now includes the ability to create MABs.
+
+ - Support for OS/2 has been extended as well, and now includes
+ options for building a.out binaries.
+
+ - Support for VMS has also been extended, incorporating improved
+ processing of file specification strings, optional suppression of
+ carriage control interpretation for record-structured files,
+ improved support for the -S command line switch, a number of
+ VMS-specific bugfixes, and significantly improved performance
+ in line-oriented reading of files.
+
+ - Several hints files have been added or updated: aux.sh (updated),
+ convexos.sh (updated), irix_4.sh (updated), irix_5.sh (updated),
+ irix_6_2.sh (updated), next_3.sh (updated), next_3_2.sh (new),
+ next_3_3.sh (new), next_4.sh (new), os2/sh (updated),
+ sco.sh (updated), and solaris_2.sh (updated).
+
+ - The test driver for the regression tests now reports when a set
+ of tests have been skipped (presumable because the operation
+ they're designed to test isn't supported on the current system).
