[perl #80098] Bleadperl breaks Attribute::Lexical
If
@UNIVERSAL::ISA = "a";
and
@a::ISA = "b";
then methods are searched for in these orders:
main UNIVERSAL a b
UNIVERSAL a b UNIVERSAL a b
a b UNIVERSAL a b
b UNIVERSAL a b
For method lookup, looking at a stash twice causes no problems (except
for a SUPER bug I’ve just found--to be dealt with separately).
My fix to next::method in a5cd004 which made it do a second pass with
UNIVERSAL the way gv_fetchmeth does did not take into account that it
might return its caller (sub a::foo { return shift->next::can }),
causing an infinite loop.
This patch makes it check, on the second pass, whether each stash is
the stash at the start of the MRO list and breaks if that is the case,
so the MROs are effectively:
main UNIVERSAL a b
UNIVERSAL a b
a b UNIVERSAL
b UNIVERSAL a
(which is what they are effectively already for method lookup).

Fix memory leak in hfreeentries
The change that made hfreeentries keep the name in place when iterat-
ing (
2d0d1ecc) caused this statement at the end of the loop to be a
no-op for named hashes, because the HvARRAY is always present at the
end of the loop (it contains the name):
if (!HvARRAY(hv)) {
/* Good. No-one added anything this time round. */
break;
}
So this line was added (by the same change) before the freeing of the
linked lists:
/* If there are no keys, there is nothing left to free. */
if (!((XPVHV*) SvANY(hv))->xhv_keys) break;
But that means that this, immediately after the freeing of the linked
lists and just before the if(!HvARRAY(hv)):
if (array != orig_array) {
Safefree(array);
}
was not being reached, resulting in a memory leak (that Nicholas
Clark found).
This is what would happen:
On entering hfreeentries, orig_array would be assigned the value
in HvARRAY.
HvARRAY = original array
orig_array = original array
Then the main loop would be entered, which would assign
HvARRAY to array:
HvARRAY = original array
orig_array = original array
array = original array
HvARRAY would be nulled out and assigned a new value by hv_auxinit:
HvARRAY = first new array
orig_array = original array
array = original array
Then the loop would repeat:
HvARRAY = first new array
orig_array = original array
array = first new array
Then the HvARRAY would once more be nulled and replaced via
hv_auxinit:
HvARRAY = second new array
orig_array = original array
array = first new array
Then the if(no keys)break; statement would be reached, exit-
ing the loop:
HvARRAY = second new array
orig_array = original array
<nothing> = first new array
So the first new array is never freed.
This commit skips the allocation of an extra array at the beginning of
the loop if there are no keys. Then it exits early at the same spot.

[perl #68560] calling closure prototype SEGVs
When a closure is created, the original sub is cloned (except that the
op tree is shared). That original sub (called the closure prototype)
is not usually accessible to perl.
An attribute handler (MODIFY_CODE_ATTRIBUTES) is passed a reference
to it, however. If that code reference is called within the attribute
handler, an ‘Undefined subroutine called’ error results, because the
op tree has not been attached yet.
If that code reference is stashed away and called after the attribute
handler returns, it will most likely crash.
This is because its pad is full of nulls.
A regular $proto->() or &$proto() call that sets up @_ will crash in
attempting to do so.
A &$proto call will bypass that, but attempting to read any lexical
variables from the containing scope will cause a crash. Any operator
that uses TARG (i.e., most of them) will crash.
So this commit puts a check for closure prototypes in pp_entersub. It
produces a new error message, ‘Closure prototype called’.
This does introduce a backward-incompatible change: code like this
used to work:
sub MODIFY_CODE_ATTRIBUTES { $'proto = $_[1] }
{ my $x; () = sub :attr { () = $x; print "hello\n" } }
&$'proto;
But writing a useful subroutine that tiptoes past the crashes is so
difficult that I think this breakage is acceptable.

Use default stack size on Windows
Perl used to request 16MB of stack instead of the default 1MB (when

thread created by the process, not just for the main thread.
Note also that we don't explicitly specify the stack size when

Filehandle method calls load IO::File on demand
When a method call on a filehandle would die because the method can not
be resolved and L<IO::File> has not been loaded, Perl now loads IO::File
via C<require> and attempts method resolution again:
open my $fh, ">", $file;
$fh->binmode(":raw"); # loads IO::File and succeeds
This also works for globs like STDOUT, STDERR and STDIN:
STDOUT->autoflush(1);
Because this on-demand load only happens if method resolution fails, the
legacy approach of manually loading an IO::File parent class for partial
method support still works as expected:
use IO::Handle;
open my $fh, ">", $file;
$fh->autoflush(1); # IO::File not loaded

Remove makeaperl, never used, a wrapper for ExtUtils::MakeMaker::makeaperl
makeaperl was added in perl5.000k, wrapped as makeaperl.SH in perl5.000l, but
neither used in the core build nor installed. All it does is acts as a
command-line wrapper to makeaperl() in ExtUtils::MakeMaker.

Generate perlmain.c using ExtUtils::Miniperl, instead of writemain.SH.
This allows writemain.SH to be removed. This also has the side effect of testing
that ExtUtils::Miniperl actually works. :-)

Skip eintr.t on VMS.
It's doing select() on a pipe, but only sockets work with select(),
and the read() on a pipe is not interruptible by an alarm. That's
probably because our pipe implementation is doing mailbox reads at
AST level but the alarm signal is also an AST and can't interrupt
another AST at the same mode.

Proper Makefile dependencies for the x2p/s2p rule.
Without this, a parallel make for a static build can fail, as x2p/Makefile
uses ../perl for a static build, but there was no rule to ensure that ../perl
was built.
A static build currently still fails some tests, I think because Encode doesn't
link all encodings staticly.

Andy Dougherty points out that after Configure has run, the "less"
config variable is no longer useful, as described in Porting/Glossary.

reg_fold.t: Add tests for simple Latin1 folds
fold_grind.t does a comprehensive series of tests, but it doesn't test

regcomp.c: Handle EXACTFU nodes in optimizer
This patch also changes the optimizer to include the other member of a

regcomp.c: Use hex instead of octal for debug ords
The ordinals that are output in the debugging output have been in octal,
which is ok for the low controls, but for above Latin1, the standard is
hex, so this changes them all to correspond. If desired the low
controls could be changed back to be in octal.
