5.002 beta 1

If you're adventurous, have a look at

    ftp://ftp.sems.com/pub/outgoing/perl5.0/perl5.002beta1.tar.gz

Many thanks to Andy for doing the integration.

Obviously, if you consult the bugs database, you'll note there are
still plenty of buglets that need fixing, and several enhancements that
I've intended to put in still haven't made it in (Hi, Tim and Ilya).
But I think it'll be pretty stable.  And you can start to fiddle around
with prototypes (which are, of course, still totally undocumented).

Packrats, don't worry too much about readvertising this widely.
Nowadays we're on a T1 here, so our bandwidth is okay.

Have the appropriate amount of jollity.

Larry

+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.
+
+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>

+ context.
+ 
+     <4.input-lineno-assign>
+     # perl -w does not complain about assignment to $. (Is this just a feature?)

+From: Hans Mulder
+Files patched: pp_hot.c toke.c

+
+NETaa13779: foreach didn't use savestack mechanism
+From: Hans Mulder
+Files patched: cop.h pp_ctl.c
+ The foreach mechanism saved the old scalar value on the context stack
+ rather than the savestack.  It could consequently get out of sync if
+ unexpectedly unwound.
+
+NETaa13785: GIMME sometimes used wrong context frame
+From: Greg Earle
+Files patched: embed.h global.sym op.h pp_ctl.c proto.h
+ The expression inside the return was taking its context from the immediately
+ surrounding block rather than the innermost surrounding subroutine call.
+
+NETaa13794: TieHash produces ${pack} warnings
+From: Stanley Donald Capelik x74321 24-5200 021876
+Files patched: lib/TieHash.pm

+
+NETaa13797: could modify sv_undef through auto-vivification
+From: Ilya Zakharevich
+Files patched: pp.c
+ Inserted the missing check for readonly values on auto-vivification.
+
+NETaa13798: if (...) {print} treats print as quoted
+From: Larry Wall
+Files patched: toke.c
+ The trailing paren of the condition was setting expectations to XOPERATOR
+ rather than XBLOCK, so it was being treated like ${print}.
+
+NETaa13926: commonality was not detected in assignments using COND_EXPR
+From: Mark Hanson
+Files patched: opcode.h opcode.pl
+ The assignment compiler didn't check the 2nd and 3rd args of a ?:
+ for commonality.  It still doesn't, but I made ?: into a "dangerous"
+ operator so it is forced to treat it as common.
+
+NETaa13957: was marking the PUSHMARK as modifiable rather than the arg
+From: David Couture
+Files patched: op.c sv.c
+ It was marking the PUSHMARK as modifiable rather than the arg.
+
+NETaa13962: documentation of behavior of scalar <*> was unclear
+From: Tom Christiansen
+Files patched: pod/perlop.pod
+ Added the following to perlop:
+ 
+ A glob only evaluates its (embedded) argument when it is starting a new
+ list.  All values must be read before it will start over.  In a list
+ context this isn't important, because you automatically get them all
+ anyway.  In a scalar context, however, the operator returns the next value
+ each time it is called, or a FALSE value if you've just run out.  Again,
+ FALSE is returned only once.  So if you're expecting a single value from
+ a glob, it is much better to say
+ 
+     ($file) = <blurch*>;
+ 
+ than
+ 
+     $file = <blurch*>;
+ 
+ because the latter will alternate between returning a filename and
+ returning FALSE.
+ 
+
+NETaa13992: regexp comments not seen after + in non-extended regexp
+From: Mark Knutsen
+Files patched: regcomp.c
+ The code to skip regexp comments was guarded by a conditional that only
+ let it work when /x was in effect.
+
+NETaa14014: use subs should not count as definition, only as declaration
+From: Keith Thompson
+Files patched: sv.c
+ On *foo = \&bar, doesn't set GVf_IMPORTED if foo and bar are in same package.
+
+NETaa14021: sv_inc and sv_dec "upgraded" magical SV to non-magical
+From: Paul A Sand
+Also: Andreas Koenig
+Files patched: sv.c
+ The sv_inc() and sv_dec() routines "upgraded" null magical SVs to non-magical.
+
+NETaa14086: require should check tainting
+From: Karl Simon Berg
+Files patched: pp_ctl.c
+ Since we shouldn't allow tainted requires anyway, it now says:
+ 
+   Insecure dependency in require while running with -T switch at tst.pl line 1.
+
+NETaa14104: negation fails on magical variables like $1
+From: tim
+Files patched: pp.c
+ Negation was failing on magical values like $1.  It was testing the wrong
+ bits and also failed to provide a final "else" if none of the bits matched.
+
+NETaa14107: deep sort return leaked contexts
+From: Quentin Fennessy
+Files patched: pp_ctl.c
+ Needed to call dounwind() appropriately.
+
+NETaa14129: attempt to localize via a reference core dumps
+From: Michele Sardo
+Files patched: op.c pod/perldiag.pod
+ Now produces an error "Can't localize a reference", with explanation in
+ perldiag.
+
+NETaa14138: substr() and s/// can cause core dump
+From: Andrew Vignaux
+Files patched: pp_hot.c
+ Forgot to call SvOOK_off() on the SV before freeing its string.
+
+NETaa14145: ${@INC}[0] dumped core in debugger
+From: Hans Mulder
+Files patched: sv.c
+ Now croaks "Bizarre copy of ARRAY in block exit", which is better than
+ a core dump.  The fact that ${@INC}[0] means $INC[0] outside the debugger
+ is a different bug.
+
+NETaa14147: bitwise assignment ops wipe out byte of target string
+From: Jim Richardson
+Files patched: doop.c
+ The code was assuming that the target was not either of the two operands,
+ which is false for an assignment operator.
+
+NETaa14153: lexing of lexicals in patterns fooled by character class
+From: Dave Bianchi
+Files patched: toke.c
+ It never called the dwimmer, which is how it fooled it.
+
+NETaa14154: allowed autoloaded methods by recognizing sub method; declaration
+From: Larry Wall
+Files patched: gv.c
+ Made sub method declaration sufficient for autoloader to stop searching on.
+
+NETaa14156: shouldn't optimize block scope on tainting
+From: Pete Peterson
+Files patched: op.c toke.c
+ I totally disabled the block scope optimization when running tainted.
+
+NETaa14157: -T and -B only allowed 1/30 "odd" characters--changed to 1/3
+From: Tor Lillqvist
+Files patched: pp_sys.c
+ Applied suggested patch.

+NETaa14160: deref of null symbol should produce null list
+From: Jared Rhine

+ 
+ The reason fixing this also fixes the s///e problem is that the lexer

+ Date: Thu, 28 Sep 95 17:18:54 -0700
+ From: lwall@scalpel.netlabs.com (Larry Wall)
+ 
+ : No.  Larry's currently got the patch pumpkin for all such core perl topics.
+ 
+ I dunno whether you should let me have the patch pumpkin or not.  To fix
+ a Sev 2 I just hacked in rudimentary prototypes.  :-)
+ 
+ We can now define true unary subroutines, as well as argumentless
+ subroutines:
+ 
+     sub baz () { 12; }			# Must not have argument
+     sub bar ($) { $_[0] * 7 }		# Must have exactly one argument
+     sub foo ($@) { print "@_\n" }	# Must have at least one argument
+     foo bar baz / 2 || "oops", "is the answer";
+ 
+ This prints "42 is the answer" on my machine.  That is, it's the same as
+ 
+     foo( bar( baz() / 2) || "oops", "is the answer");
+ 
+ Attempting to compile
+ 
+     foo;
+ 
+ results in
+ 
+     Too few arguments for main::foo at ./try line 8, near "foo;"
+ 
+ Compiling
+ 
+     bar 1,2,3;
+ 
+ results in
+ 
+     Too many arguments for main::bar at ./try line 8, near "foo;"
+     
+ But
+ 
+     @array = ('a','b','c');
+     foo @array, @array;
+     
+ prints "3 a b c" because the $ puts the first arg of foo into scalar context.
+ 
+ The main win at this point is that we can say
+ 
+     sub AAA () { 1; }
+     sub BBB () { 2; }
+ 
+ and the user can say AAA + BBB and get 3.
+ 
+ I'm not quite sure how this interacts with autoloading though.  I fear
+ POSIX.pm will need to say
+ 
+     sub E2BIG ();
+     sub EACCES ();
+     sub EAGAIN ();
+     sub EBADF ();
+     sub EBUSY ();
+     ...
+     sub _SC_STREAM_MAX ();
+     sub _SC_TZNAME_MAX ();
+     sub _SC_VERSION ();
+ 
+ unless we can figure out how to efficiently declare a default prototype
+ at import time.  Meaning, not using eval.  Currently
+ 
+     *foo = \&bar;
+ 
+ (the ordinary import mechanism) implicitly stubs &bar with no prototype if
+ &bar is not yet declared.  It's almost like you want an AUTOPROTO to
+ go with your AUTOLOAD.
+ 
+ Another thing to rub one's 5 o'clock shadow over is that there's no way
+ to apply a prototype to a method call at compile time.
+ 
+ And no, I don't want to have the
+ 
+     sub howabout ($formal, @arguments) { ... }
+ 
+ argument right now.

+From: Wayne Berke

+ The previous workaround prevented another bug (NETaa14529) from being fixed,
+ so I've backed it out.  I'll need to think more about how to detect failure
