=head1 NAME
-perldelta - what's new for perl v5.7.0
+perldelta - what will be new for perl v5.8.0
=head1 DESCRIPTION
-This document describes differences between the 5.6.0 release and
-the 5.7.0 release.
-
-=head1 Security Vulnerability
-
-A potential security vulnerability in the optional suidperl component
-of Perl has been identified. The suidperl is neither built nor
-installed by default. As of August the 20th, 2000, the only known
-vulnerable platform is Linux, most likely all Linux distributions.
-The CERT and various vendors have been alerted about the vulnerability.
-
-The problem was caused by Perl trying to report a suspected security
-exploit attempt using an external program, /bin/mail. In Linux
-platforms the /bin/mail program had an undocumented feature which gave
-access to a root shell, resulting in a serious compromise, instead of
-reporting the exploit attempt. If you don't have /bin/mail or if you
-have 'safe suid scripts' or if you haven't installed the suidperl, you
-are safe.
-
-The exploit attempt reporting feature has been completely removed from
-the Perl 5.7.0 release, so that particular vulnerability isn't there
-anymore. However, further security vulnerabilities are,
-unfortunately, always possible. The suidperl code is being reviewed
-and if deemed too risky to continue being supported, in the extreme
-case it may be completely removed in future releases. In any case,
-suidperl should only be used by security experts who know exactly what
-they are doing and why they are using suidperl instead of some other solution.
-A good tool for similar needs is sudo: http://www.courtesan.com/sudo/
-
-=head1 Incompatible Changes
-
-=head2 Arrays Now Always Interpolate Into Double-Quoted Strings
-
-Constructs like "foo@bar" now always assume the C<@bar> to be an array,
-regardless of whether it is known that C<@bar> is an array.
-
-=head2 bless(REF, REF) is now a fatal error
-
-The semantics of bless(REF, REF) were unclear and until someone proves
-it to make some sense, it is forbidden.
-
-=head2 The eg/* Directory Removed
-
-The very dusty examples in the eg/ directory have been removed.
-Suggestions for new shiny examples welcome but the main issue is that
-the examples need to be documented, tested, and--most importantly--maintained.
-
-=head2 The lib/chat2.pl
-
-The obsolete chat2 library that should never have been allowed
-to escape the laboratory has been decommissioned.
-
-=head2 Unimplemented (But Recognized) POSIX Regex Features Now Fatal
-
-The unimplemented POSIX regex features [[.cc.]] and [[=c=]] are still
-recognized but now cause fatal errors. The previous behaviour of
-ignoring them by default and warning if requested was unacceptable
-since it, in a way, falsely promised that the features could be used.
-
-=head2 lstat(FILEHANDLE) now warns
-
-lstat(FILEHANDLE) now gives a warning because the operation makes no sense.
-In future releases this may become a fatal error.
-
-=head2 Obsolete String Comparison Operators Removed
-
-The long since deprecated uppercase aliases for the string comparison
-operators (EQ, NE, LT, LE, GE, GT) have now been removed.
-
-=head2 The Regular Expression Submatches Are Now Unset When Backtracking
-
-The regular expression captured submatches ($1, $2, ...) are now
-consistently unset if the match fails, instead of leaving false
-data lying around in them.
-
-=head2 tr///CU Removed, Not To Return
-
-The tr///C and tr///U features have been removed and will not return;
-the interface was a mistake. Sorry about that. For similar
-functionality, see pack('U0', ...) and pack('C0', ...).
-
-=head1 Core Enhancements

-
-no Module; now works even if there is no "sub unimport" in the Module.

-and directories in an easy, portable, and secure way.
-
-=item *
-
-The Storable extension, version 0.7.2, released the 14th of August
-2000, has been added to the Perl distribution. Storable gives
-persistence to Perl data structures by allowing the storage and
-retrieval of Perl data to and from files in a fast and compact binary
-format.

-27th of April 2000.
-
-=item *
-
-The English module can now be used without the infamous performance
-hit by saying
-
- use English '-no_performance_hit';
-
-(Assuming, of course, that one doesn't need the troublesome variables
-C<$`>, C<$&>, or C<$'>.) Also, introduce C<@LAST_MATCH_START> and
-C<@LAST_MATCH_END> English aliases for C<@-> and C<@+>.
-
-=item *
-
-File::Find now has pre- and postprocessing callbacks.
-It also correctly changes directories when chasing symbolic links.
-Callbacks doing (naughtily) "next;" instead of "return;" now work.
-
-=item *
-
-File::Glob::glob() renamed to File::Glob::bsd_glob() to avoid
-prototype mismatch with CORE::glob().
-
-=item *
-
-File::Spec has been updated to version 0.82, released the
-1st of July 2000.
-
-=item *
-

-
-=item *
-
-Math::Complex now handles extreme values (e.g. cplx(1E20, 1E30)) more
-gracefully.
-
-=item *
-
-The podlators bundle has been updated to version 1.02, released the
-25th of April 2000. It contains the modules Pod::Man 1.04, Pod::Text
-2.04, and modules Pod::Text::Color and Pod::Text::Termcap (no version
-numbers).
-
-=item *
-
-Pod::LaTeX has been updated to version 0.52, released the 15th of May
-2000. Note that this is a complete rewrite which translates pod much
-better, has many more options and much better documentation. It also
-now uses the Pod::Parser backend, meaning that Pod::LaTeX will stay
-abreast other pod translators.
-
-=item *
-
-Pod::Parser has been updated to version 1.17, released the 25th of
-July 2000. It contains the modules Pod::Checker 1.20, Pod::Find 0.21,

-August 2000.
-
-=item *
-
-The Test module has been updated to version 1.14, released the 21st of June
-1999. This is for all practical purposes identical to the previous release
-of Test included with the Perl distribution, 1.13, but upgrading the module
-stops the CPAN module from suggesting an upgrade.
-
-=item *
-
-Test::Harness output now prettier on failed test.
-
-=item *
-
-Text::Wrap::wtbrap now handles multiline strings properly.
-

-Perlbug is now much more robust. It also sends the bug report to perl.org,
-not perl.com.
-
-=head2 perlcc now more cc-like and more robust
-
-The perlcc utility has been rewritten and its user interface (that is,
-command line) is much more like that of the UNIX C compiler, cc.

-documentation embedded in the *.xs files.
-

-=item *
-
-The return values of failing backticks (`, qx{}) are now documented
-in perlop.

-glossing over.
-
-=item *
-
-Document that the C<$(> special variable does not interpolate
-in regular expressions.
-
-=item *
-
-The timeout unit of IO::Select is now documented to be identical
-to the timeout unit of the 4-arg select(), that is, (optionally
-fractional) seconds, or an undef to wait indefinitely.
-
-=item *
-
-Document the C<D> and C<d> magic types.
-
-=item *
-
-The ordering of PODs in perl.pod is now more sensible.

-
-Numerous missing warning/error messages added to perldiag.
-
-=item *
-
-Changed the description of perl6 in perlfaq1.
-
-=item *

-
-=item *
-
-perltrap cleaned up.
-
-=item *
-
-Add perlxstut example for passing/returning refs to arrays.
-
-=item *
-
-POSIX module documentation embellished.
-
-=item *
-
-Clarified the status of shadow password support.
-
-=item *
-
-Reminded that preprocessors and source filters can alter
-your code before Perl sees it and therefore debugging
-can be somewhat surprising. ("I didn't write *that*!")
-
-=item *
-
-Removed incorrect documentation about implicit split to @_
-in list context, which never really worked in Perl 5 anyway.
-
-=item *
-
-Explain that split /^/ is split /^/m.
-
-=item *
-
-Added many more sprintf() examples in perlfunc.
-
-=item *
-
-Documented the handling of negative indices to tied arrays.
-
-=item *
-
-The C<$yday> in localtime()/gmtime() is 0..364, not 1..365.
-
-=item *
-
-Documented that tr() is not tr(1): that is, do not expect regular expressions.
-
-=item *
-
-Warn about the vagaries of UDP.
-
-=item *
-
-The uninitialized variable warnings now say "concat or string" or
-"join or string" instead of just "concat" or "join" since many users
-found the "concat" a bit surprising when they were doing "just"
-variable interpolation.
-
-=item *
-
-Documented that the values() are aliases, not copies.

-
-=head1 Performance Enhancements
-
-map() that changes the size of the list should now work faster.
-
-=head1 Installation and Configuration Improvements
-
-=head2 INSTALL now explains 64-bit configuration.
-
-In some platforms Perl can be configured to use 64-bit integers,
-allowing 4 billion times better...sorry, switched accidentally to
-marketdroid mode for a moment in there. (In platforms which are
-natively 64-bit this makes no difference.)
-
-=head2 Policy.sh policy change
-
-If you are reusing a Policy.sh file (see INSTALL) and you use
-Configure -Dprefix=/foo/bar and in the old Policy $prefix eq
-$siteprefix and $prefix eq $vendorprefix, all of them will now be
-changed to the new prefix, /foo/bar. (Previously only $prefix
-changed.) If you do not like this new behaviour, specify prefix,
-siteprefix, and vendorprefix explicitly.
-
-=head2 Additional Library Locations
-
-A new optional location for Perl libraries, otherlibdirs, is available.
-It can be used for example for vendor add-ons without disturbing Perl's
-own library directories.
-
-=head2 gcc automatically tried if 'cc' does not seem to be working
-
-In many platforms the vendor-supplied 'cc' is too stripped-down to
-build Perl (basically, the 'cc' doesn't do ANSI C). If this seems
-to be the case and the 'cc' does not seem to be the GNU C compiler
-'gcc', an automatic attempt is made to find and use 'gcc' instead.
-
-=head2 If gcc seems to be from a different operating system release ...
-
-gcc needs to closely track the operating system release because gcc
-wants to have its own versions of the operating system header files
-fixed to be clean enough for gcc's tastes. Therefore using a gcc
-compiled for a different release of the operating system is often a
-bad idea. If Configure can find out the operating system release that
-was used to compile the gcc and that release is different from the one
-being used now, gcc gives a clearly visible warning that trouble may
-lie ahead.
-
-=head2 If no binary compatibility with 5.005 wanted, no 5.005 modules, either
-
-If no binary compatibility with the 5.005 release is wanted, Configure
-does not suggest including the 5.005 modules in the @INC.

-line number, the C<$.> no longer gets corrupted, all debugger output now
-goes correctly to the socket if RemotePort is set.

-Module name now mandatory after the C<-M> switch.
-
-=item *
-
-Fixed numerous memory leaks, especially in eval "".
-
-=item *
-
-Modulus of unsigned numbers now works (4063328477 % 65535 used to
-return 27406, instead of 27047).
-
-=item *
-
-msgrcv() no longer warns about uninitialized input scalar.
-
-=item *
-
-Some "not a number" warnings introduced in 5.6.0 eliminated to be
-more compatible with 5.005. Infinity is now recognized as a number.
-
-=item *
-
-our() variables will not cause "will not stay shared" warnings
-
-=item *
-
-pack "Z" now correctly terminates the string with an "\0".
-
-=item *
-
-Fix password routines which in some shadow password platforms
-(e.g. HP-UX) caused getpwent() to return every other entry.
-
-=item *
-
-POSIX::STDERR_FILENO (not POSIX::STRERR_FILENO).
-
-=item *
-
-printf() no longer resets the numeric locale to "C".
-
-=item *
-
-C<q(a\\b)> now parses as C<'a\\b'>.
-
-=item *
-
-In quad (64-bit) platforms numbers now stay integers longer
-(as opposed to converting automatically to floating point numbers).
-
-=item *
-
-Printing quads (64-bit integers) with printf/sprintf works now
-without q L ll prefixes (assuming you are on a quad-capable platform).
-
-=item *
-
-Regular expressions on references and overloaded scalars now work.
-
-=item *
-
-Multiline matching of C<"a\nxb\n" =~ /(?!\A)x/m> now works.

-(they were accidentally using the context of the sort() itself).
-
-=item *
-
-Changed the POSIX character class C<[[:space:]]> to include the (very
-rare) vertical tabulator character. Added a new POSIX-ish character
-class C<[[:blank:]]> which stands for horizontal whitespace (currently,
-the space and the tabulator).
-

-
-sprintf() format specs like C<%v-*d> now work.
-
-=item *
-
-The (nonsensical) C<%#p> format made illegal.

-
-Several Unicode fixes (but still not perfect).
-
-BOMs (byte order marks) in the beginning of Perl files
-(scripts, modules) should now be transparently skipped.
-UTF16 encoded Perl files should now be read correctly.
-
-The character tables have been updated to new Unicode 3.0 features.
-
-chr() for values greater than 127 now create utf8 when under use
-utf8.
-
-Comparing with utf8 data does not magically upgrade non-utf8 data into
-utf8.
-
-C<IsAlnum>, C<IsAlpha>, and C<IsWord> now match titlecase.
-
-Concatenation with the C<.> operator or via variable interpolation,
-C<eq>, C<substr>, C<reverse>, C<quotemeta>, the C<x> operator,
-substitution with C<s///>, single-quoted UTF8, should now work--in
-theory.
-
-The C<tr///> operator now works I<slightly> better but is still rather
-broken. Note that the C<tr///CU> functionality has been removed (but
-see pack('U0', ...)).
-
-Zero entries were missing from the Unicode classes like C<IsDigit>.
-
-=item *
-
-Unsignedness could disappear from a scalar causing later numeric
-comparisons to fail.
-
-=item *
-
-vec() now drops numericalness.

-
-=head1 New or Changed Diagnostics
-
-All regular expression compilation error messages are now hopefully
-easier to understand both because the error message now comes before
-the failed regex and because the point of failure is now clearly
-marked.
-
-The various "opened only for", "on closed", "never opened" warnings
-drop the C<main::> prefix for filehandles in the C<main> package,
-for example C<STDIN> instead of <main::STDIN>.

-
-(perhaps you forgot to load "%s"?)
-
-(F) This is an educated guess made in conjunction with the message
-"Can't locate object method \"%s\" via package \"%s\"". It often means
-that a method requires a package that has not been loaded.

-
-Ambiguous range in transliteration operator
-
-(F) You wrote something like C<tr/a-z-0//> which doesn't mean anything at
-all. To include a C<-> character in a transliteration, put it either
-first or last. (In the past, C<tr/a-z-0//> was synonymous with
-C<tr/a-y//>, which was probably not what you would have expected.)
-

-
-The "Unrecognized escape" warning has been extended to include C<\8>,
-C<\9>, and C<\_>. There is no need to escape any of the C<\w> characters.

-=head1 Changed Internals
-
-=head2 apidoc
-
-perlapi.pod (a companion to perlguts) now attempts to document the
-internal API.
-
-=head2 microperl
-
-There is now a way to build a really minimal perl called microperl.
-Building microperl does not require even running Configure;
-C<make -f Makefile.micro> should be enough. Beware: microperl makes
-many assumptions, some of which may be too bold; the resulting
-executable may crash or otherwise misbehave in wondrous ways. For
-careful hackers only.
-
-=head2 Publicize More Functions
-
-Added rsignal(), whichsig(), do_join() to the publicized API.
-
-=head2 Propagating Exception Objects via Perl_croak() IN XS code
-
-Made possible to propagate customized exceptions via croak()ing.
-
-=head2 UTF8 Interfaces
-
-Added is_utf8_char(), is_utf8_string(), bytes_to_utf8(), and utf8_to_bytes().
-
-=head2 xsub attributes
-
-Now xsubs can have attributes just like subs.

-=head2 Unicode Support Still Far From Perfect
-
-We're working on it. Stay tuned.
-
-=head2 EBCDIC Still A Lost Platform
-
-The plan is to bring them back.
-
-=head2 Building Extensions Can Fail Because Of Largefiles
-
-Certain extensions like mod_perl and BSD::Resource are known to have
-issues with `largefiles', a change brought by Perl 5.6.0 in where file
-offsets are by default 64 bits wide (assuming the platform supports
-such large files). Modules may fail to compile at all or compile and
-work incorrectly. Currently there is no good solution for the problem
-but Configure now stores the flags and libraries that affect the
-largefileness to the %Config hash, the extensions that are having
-problems can try configuring themselves without the largefileness.
-This is admittedly not a clean solution.
