[perl #114942] Correct scoping for ‘for my $x(){} $x’
This was broken by commit
60ac52eb5d5.
What that commit did was to merge two different queues that the
lexer had for pending tokens. Since bison requires that yylex
return exactly one token for each call, when the lexer sometimes has
to set aside tokens in a queue and return them from the next few
calls to yylex.
Formerly, there were two mechanism: the forced token queue (used by
force_next), and PL_pending_ident. PL_pending_ident was used for
names that had to be looked up in the pads.
$foo was handled like this:
First call to yylex:
1. Put '$foo' in PL_tokenbuf.
2. Set PL_pending_ident.
3. Return a '$' token.
Second call:
PL_pending_ident is set, so call S_pending_ident, which looks up
the name from PL_tokenbuf, and return the THING token containing
the appropriate op.
The forced token queue took precedence over PL_pending_ident. Chang-
ing the order (necessary for parsing ‘our sub foo($)’) caused some
XS::APItest tests to fail. So I concluded that the two queues needed
to be merged.
As a result, the $foo handling changed to this:
First call to yylex:
1. Put '$foo' in PL_tokenbuf.
2. Call force_ident_maybe_lex (S_pending_ident renamed and modi-
fied), which looks up the symbol and adds it to the forced
token queue.
3. Return a '$' token.
Second call:
Return the token from the forced token queue.
That had the unforeseen consequence of changing this:
for my $x (...) { ... }
$x;
such that the $x was still visible after the for loop. It only hap-
pened when the $ was the next token after the closing }:
$ ./miniperl -e 'for my $x(()){} $x = 3; warn $x'
Warning: something's wrong at -e line 1.
$ ./miniperl -e 'for my $x(()){} ;$x = 3; warn $x'
3 at -e line 1.
This broke Class::Declare.
The name lookup in the pad must not happen before the '$' token is
emitted. At that point, the parser has not yet created the for loop
(which includes exiting its scope), as it does not yet know whether
there is a continue block. (See the ‘FOR MY...’ branch of the
barestmt rule in perly.y.) So we must delay the name lookup till the
second call.
So we rename force_ident_maybe_lex back to S_pending_ident, removing
the force_next stuff. And we add a new force_ident_maybe_lex function
that adds a special ‘pending ident’ token to the forced token queue.
The part of yylex that handles pending tokens (case LEX_KNOWNEXT) is
modified to account for these special ‘pending ident’ tokens and call
S_pending_ident.

blksize_t st_blksize A file system-specific preferred I/O block size for
this object. In some file system types, this may
vary from file to file.
blkcnt_t st_blocks Number of blocks allocated for this object.

"The unit for the st_blocks member of the stat structure is not
defined within IEEE Std 1003.1-2001. In some implementations it is 512
bytes. It may differ on a file system basis. There is no correlation

[perl #114924] Make method calls work with ::SUPER packages
Perl caches SUPER methods inside packages named Foo::SUPER. But this
interferes with actual method calls on those packages (SUPER->foo,
foo::SUPER->foo).
The first time a package is looked up, it is vivified under the name
with which it is looked up. So *SUPER:: will cause that package
to be called SUPER, and *main::SUPER:: will cause it to be named
main::SUPER.
main->SUPER::isa used to be very sensitive to the name of the
main::FOO package (where the cache is kept). If it happened to be
called SUPER, that call would fail.
Fixing that bug (commit
3c104e59d83f) caused the CPAN module named
SUPER to fail, because SUPER->foo was now being treated as a
SUPER::method call. gv_fetchmeth_pvn was using the ::SUPER suffix to
determine where to look for the method. The package passed to it (the
::SUPER package) was being used to look for cached methods, but the
package with ::SUPER stripped off was being used for the rest of
lookup.
3c104e59d83f made main->SUPER::foo work by treating SUPER
as main::SUPER in that case. Mentioning *main::SUPER:: or doing a
main->SUPER::foo call before loading SUPER.pm also caused it to fail,
even before
3c104e59d83f.
Instead of using publicly-visible packages for internal caches, we
should be keeping them internal, to avoid such side effects.
This commit adds a new member to the HvAUX struct, where a hash of GVs
is stored, to cache super methods. I cannot simpy use a hash of CVs,
because I need GvCVGEN. Using a hash of GVs allows the existing
method cache code to be used.
This new hash of GVs is not actually a stash, as it has no HvAUX
struct (i.e., no name, no mro_meta). It doesn’t even need an @ISA
entry as before (which was only used to make isa caches reset), as it
shares its owner stash’s mro_meta generation numbers. In fact, the
GVs inside it have their GvSTASH pointers pointing to the owner stash.
In terms of memory use, it is probably the same as before. Every
stash and every iterated or weakly-referenced hash is now one pointer
larger than before, but every SUPER cache is smaller (no HvAUX, no
*ISA + @ISA + $ISA[0] + magic).
The code is a lot simpler now and uses fewer stash lookups, so it
should be faster.
This will break any XS code that expects the gv_fetchmeth_pvn to treat
the ::SUPER suffix as magical. This behaviour was only barely docu-
mented (the suffix was mentioned, but what it did was not), and is
unused on CPAN.

best tradeoff in the long run, as it makes code using experimental my

regexec.c: Avoid unnecessary calculation
When matching an EXACT node and the target string and the pattern differ
in utf8ness, the code prior to this patch calculated each code point from
the utf8 version in order to do the EXACT comparision with the non-utf8
version. But it is unnecessary to do this full calculation. Code
points above Latin1 cannot possibly match a non-UTF8 string; there is no
need to know precisely which code point it is in order to know that it
won't match. Similarly, invariant code points can be checked directly;
and the Latin1 variants can be downgraded for comparison by a simple
macro.

Bring bleadperl up to parity with CPAN for version.pm
Please find attached a patch to bleadperl to bring up to date with the
CPAN release of version.pm. This release was to deal primarily with an
edge case in numifying alpha decimal versions:
https://rt.cpan.org/Ticket/Display.html?id=79259
I've also synchronized all of the other version.pm test cases, so that
the code in core is identical to the CPAN release.

Allow lexical sub redefinition inside eval
For non-clonable state subs, this already happened to work.
For any clonable subs, we need to clone the sub as soon as it
is defined.
For redefined state subs, we need to apply the new sub to all recur-
sion levels, as state subs are shared.

Move my sub prototype CVs to the pad names
my subs are cloned on scope entry. To make closures work, a stub
stored in the pad (and closed over elsewhere) is cloned into.
But we need somewhere to store the prototype from which the clone is
made. I was attaching the prototype via magic to the stub in the pad,
since the pad is available at run time, but not the pad names.
That leads to lots of little games all over the place to make sure
the prototype isn’t lost when the pad is swiped on scope exit
(SAVEt_CLEARSV in scope.c). We also run the risk of losing it if an
XS module replaces the sub with another.
Instead, we should be storing it with the pad name. The previous com-
mit made the pad names available at run time, so we can move it there
(still stuffed inside a magic box) and delete much code.
This does mean that newMYSUB cannot rely on the behaviour of non-clon-
able subs that close over variables (or subs) immediately. Previ-
ously, we would dig through outer scopes to find the stub in cases
like this:
sub y {
my sub foo;
sub x {
sub {
sub foo { ... }
}
}
}
We would stop at x, which happens to have y’s stub in its pad, so
that’s no problem.
If we attach it to the pad name, we definitely have to dig past x to
get to the pad name in y’s pad.
Usually, immediate closures do not store the parent pad index, since
it will never be used. But now we do need to use it, so we modify the
code in pad.c:S_pad_findlex to set it always for my/state.
