See INSTALL + for how this is supposed to work. The default is + still the same as in 5.003_02, namely don't use + any fancy new PerlIO stuff. + + Don't look for sigvec() since we don't actually use it. + (Plus, it used to print an alarming misleading message about + race conditions.) + + Look for stdio's _filbuf under the possible names of + _filbuf, __filbuf, and _fill. + + New $useshrplib variable to control whether we build a shared + libperl.so. The name of the library is in $libperl. + Always install it in $installarchlib/CORE/$libperl. + + Check for and for NetBSD. + + Replace old $altmake stuff with newer autoconf-ish + $make_set_make, which checks if $make sets $(MAKE). Now you + choose an alternate make with sh Configure -Dmake=gmake (or + whatever). + + Remove 'ln' for the list of essential commands.

If you build suidperl on your system, it -is strongly recommended that you replace any existing copies with -version 5.003 or later immediately. - -The changes in 5.003 have been held to a minimum, in the hope that this -will simplify installation and testing at sites which may be affected -by the security hole in suidperl. In brief, 5.003 does the following: - -- Plugs security hole in suidperl mechanism on affected systems - -- MakeMaker was also updated to version 5.34, and extension Makefile.PLs - were modified to match it. - -- The following hints files were updated: bsdos.sh, hpux.sh, linux.sh, - machten.sh, solaris_2.sh - -- A fix was added to installperl to insure that file permissions were - set correctly for the installed C header files. - -- t/op/stat.t was modified to work around MachTen's belief that /dev/null - is a terminal device. - -- Incorporation of Perl version information into the VMS' version of - config.h was changed to make it compatible with the older VAXC. - -- Minor fixes were made to VMS-specific C code, and the routine - VMS::Filespec::rmsexpand was added. - ----------------- -Version 5.002_01 ----------------- - -- The EMBED namespace changes are now used by default, in order to better - segregate Perl's C global symbols from those belonging to embedding - applications or to libraries. This makes it necessary to rebuild dynamic - extensions built under previous versions of Perl without the EMBED option. - The default use of EMBED can be overridden by placing -DNO_EMBED on the - cc command line. - - The EMBED change is the beginning of a general cleanup of C global - symbols used by Perl, so binary compatibility with previously - compiled dynamic extensions may be broken again in the next few - releases. - -- Several bugs in the core were fixed, including the following: - - made sure FILE * for -e temp file was closed only once - - improved form of single-statement macro definitions to keep - as many ccs as possible happy - - fixed file tests to insure that signed values were used when - computing differences between times. - - fixed toke.c so implicit loop isn't doubled when perl is - invoked with both the -p and -n switches - -- The new SUBVERSION number has been included in the default value for - architecture-specific library directories, so development and - production architecture-dependent libraries can coexist. - -- Two new magic variables, $^E and $^O, have been added. $^E contains the - OS-specific equivalent of $!. $^O contains the name of the operating - system, in order to make it easily available to Perl code whose behavior - differs according to its environment. The standard library files have - been converted to use $^O in preference to $Config{'osname'}. - -- A mechanism was added to allow listing of locally applied patches - in the output of perl -v. - -- Miscellaneous minor corrections and updates were made to the documentation. - -- Extensive updates were made to the OS/2 and VMS ports - -- The following hints file were updated: bsdos.sh, dynixptx.sh, - irix_6_2.sh, linux.sh, os2.sh - -- Several changes were made to standard library files: - - reduced use of English.pm and $`, $', and $& in library modules, - since these degrade module loading and evaluation of regular expressions, - respectively. - - File/Basename.pm: Added path separator to dirname('.') - - File/Copy.pm: Added support for VMS and OS/2 system-level copy - - MakeMaker updated to v5.26 - - Symbol.pm now accepts old (') and new (::) package delimiters - - Sys/Syslog.pm uses Sys::Hostname only when necessary - - chat2.pl picks up necessary constants from socket.ph - - syslog.pl: Corrected thinko 'Socket' --> 'Syslog' - - xsubpp updated to v1.935 - - -- The perlbug utility is now more cautious about sending mail, in order - to reduce the chance of accidentally send a bug report by giving the - wrong response to a prompt. - -- The -m switch has been added to perldoc, causing it to display the - Perl code in target file as well as any documentation. - -------------- -Version 5.002 -------------- - -The main enhancement to the Perl core was the addition of prototypes. -Many of the modules that come with Perl have been extensively upgraded. - -Other than that, nearly all the changes for 5.002 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 (if any). - -Added APPLLIB_EXP for embedded perl library support. -Files patched: perl.c - -Couldn't define autoloaded routine by assignment to typeglob. -Files patched: pp_hot.c sv.c - -NETaa13525: Tiny patch to fix installman -n -From: Larry Wall -Files patched: installman - -NETaa13525: de-documented \v -Files patched: pod/perlop.pod pod/perlre.pod - -NETaa13525: doc changes -Files patched: pod/perlop.pod pod/perltrap.pod - -NETaa13525: perlxs update from Dean Roehrich -Files patched: pod/perlxs.pod - -NETaa13525: rename powerunix to powerux -Files patched: MANIFEST hints/powerux.sh - -NETaa13540: VMS uses CLK_TCK for HZ -Files patched: pp_sys.c - -NETaa13721: pad_findlex core dumps on bad CvOUTSIDE() -From: Carl Witty -Files patched: op.c sv.c toke.c - Each CV has a reference to the CV containing it lexically. Unfortunately, - it didn't reference-count this reference, so when the outer CV was freed, - we ended up with a pointer to memory that got reused later as some other kind - of SV. - -NETaa13721: warning suppression -Files patched: toke.c - (same) - -NETaa13722: walk.c had inconsistent static declarations -From: Tim Bunce -Files patched: x2p/walk.c - Consolidated the various declarations and made them consistent with - the actual definitions. - -NETaa13724: -MPackage=args patch -From: Tim Bunce -Files patched: perl.c pod/perlrun.pod - Added in the -MPackage=args patch too. - -NETaa13729: order-of-evaluation dependency in scope.c on leaving REGCONTEXT -From: "Jason Shirk" -Files patched: scope.c - Did - - I32 delta = SSPOPINT; - savestack_ix -= delta; /* regexp must have croaked */ - - instead. - -NETaa13731: couldn't assign external lexical array to itself -From: oneill@cs.sfu.ca -Files patched: op.c - The pad_findmy routine was only checking previous statements for previous - mention of external lexicals, so the fact that the current statement - already mentioned @list was not noted. It therefore allocated another - reference to the outside lexical, and this didn't compare equal when - the assigment parsing code was trying to determine whether there was a - common variable on either side of the equals. Since it didn't see the - same variable, it thought it could avoid making copies of the values on - the stack during list assignment. Unfortunately, before using those - values, the list assignment has to zero out the target array, which - destroys the values. - - The fix was to make pad_findmy search the current statement as well. This - was actually a holdover from some old code that was trying to delay - introduction of "my" variables until the next statement. This is now - done with a different mechanism, so the fix should not adversely affect - that. - -NETaa13733: s/// doesn't free old string when using copy mode -From: Larry Wall -Files patched: pp_ctl.c pp_hot.c - When I removed the use of sv_replace(), I simply forgot to free the old char*. - -NETaa13736: closures leaked memory -From: Carl Witty -Files patched: op.c pp.c - This is a specific example of a more general bug, fixed as NETaa13760, having - to do with reference counts on comppads. - -NETaa13739: XSUB interface caches gimme in case XSUB clobbers it -From: Dean Roehrich -Files patched: pp_hot.c - Applied suggest patch. Also deleted second gimme declaration as redundant. - -NETaa13760: comppad reference counts were inconsistent -From: Larry Wall -Files patched: op.c perl.c pp_ctl.c toke.c - All official references to comppads are supposed to be through compcv now, - but the transformation was not complete, resulting in memory leakage. - -NETaa13761: sv_2pv() wrongly preferred IV to NV when SV was readonly -From: "Jack R. Lawler" -Files patched: sv.c - Okay, I understand how this one happened. This is a case where a - beneficial fix uncovered a bug elsewhere. I changed the constant - folder to prefer integer results over double if the numbers are the - same. In this case, they aren't, but it leaves the integer value there - anyway because the storage is already allocated for it, and it *might* - be used in an integer context. And since it's producing a constant, it - sets READONLY. Unfortunately, sv_2pv() bogusly preferred the integer - value to the double when READONLY was set. This never showed up if you - just said - - print 1.4142135623731; - - because in that case, there was already a string value. - - -NETaa13772: shmwrite core dumps consistently -From: Gabe Schaffer -Files patched: opcode.h opcode.pl - The shmwrite operator is a list operator but neglected to push a stack - mark beforehand, because an 'm' was missing from opcode.pl. - -NETaa13773: $. was misdocumented as read-only. -From: Inaba Hiroto -Files patched: pod/perlvar.pod - <1.array-element-read-only> - % perl -le '$,=", "; $#w=5; for (@w) { $_=1; } print @w' - Modification of a read-only value attempted at -e line 1. - % perl4 -le '$,=", "; $#w=5; for (@w) { $_=1; } print @w' - 1, 1, 1, 1, 1, 1 - - This one may stay the way it is for performance reasons. - - <2.begin-local-RS> - % cat abc - a - b - c - % perl -e 'BEGIN { local $/ = ""; } print "$.:$_" while <>;' abc - 1:a - b - c - % perl -e '{ local $/ = ""; } print "$.:$_" while <>;' abc - 1:a - 2:b - 3:c - - $/ wasn't initialized early enough, so local set it back to permanently - undefined on exit from the block. - - <3.grep-x0-bug> - % perl -le 'print grep(/^-/ ?

In a scalar context, however, the operator returns the next value - each time it is called, or a FALSE value if you've just run out. Again, - FALSE is returned only once.

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().

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.

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".

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. - - Objects. See t/op/ref.t for examples. - - => 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. - - 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. - - More embeddible. See main.c and embed_h.sh. Multiple interpreters - in the same process are supported (though not with interleaved - execution yet). - - 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. - - eval is now treated more like a subroutine call. Among other things, - this means you can return from it. - - Format value lists may be spread over multiple lines by enclosing in - a do {} block. - - 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. - - Flags on the #! line are interpreted even if the script wasn't - executed directly. (And even if the script was located by "perl -x"!) - - The ?: operator is now legal as an lvalue. - - List context now propagates to the right side of && and ||, as well - as the 2nd and 3rd arguments to ?:. - - The "defined" function can now take a general expression. - - Lexical scoping available via "my". eval can see the current lexical - variables. - - The preferred package delimiter is now :: rather than '. - - 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. - - New "and" and "or" operators work just like && and || but with - a precedence lower than comma, so they work better with list operators. - - 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. - - Dynamic loading of external modules is now supported. - - There is a new quote form qw//, which is equivalent to split(' ', q//). - - 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; - - Filehandle methods are now supported: - output_autoflush STDOUT 1; - - There is now an "English" module that provides human readable translations - for cryptic variable names. - - Autoload stubs can now call the replacement subroutine with goto &realsub. - - 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. - - 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". - - 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. - - 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. - - 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. - - 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. - - 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". - - 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. - -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. - - Ordinary variables starting with underscore are no longer forced into - package main. - - s'$lhs'$rhs' now does no interpolation on either side. It used to - interplolate $lhs but not $rhs. - - The second and third arguments of splice are now evaluated in scalar - context (like the book says) rather than list context. - - Saying "shift @foo + 20" is now a semantic error because of precedence. - - "open FOO || die" is now incorrect. You need parens around the filehandle. - - The elements of argument lists for formats are now evaluated in list - context. This means you can interpolate list values now. - - You can't do a goto into a block that is optimized away. Darn. - - 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. - - 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. - - m//g now attaches its state to the searched string rather than the - regular expression. - - "reverse" is no longer allowed as the name of a sort subroutine. - - taintperl is no longer a separate executable. There is now a -T - switch to turn on tainting when it isn't turned on automatically. - - Symbols starting with _ are no longer forced into package main, except - for $_ itself (and @_, etc.). - - Double-quoted strings may no longer end with an unescaped $ or @. - - Negative array subscripts now count from the end of the array. - - The comma operator in a scalar context is now guaranteed to give a - scalar context to its arguments. - - The ** operator now binds more tightly than unary minus. - - Setting $#array lower now discards array elements so that destructors - work reasonably. - - delete is not guaranteed to return the old value for tied arrays, - since this capability may be onerous for some modules to implement. - - Attempts to set $1 through $9 now result in a run-time error.
