The KEY_require case should be setting PL_expect to XTERM (as it

because we expect a term after ‘require’, but to XOPERATOR when
there is a forced token, because we expect an operator after that

[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.

The use of "block" to describe both the file-or-device-specific sweet

it honestly because Perl just provides a wrapper around:
http://pubs.opengroup.org/onlinepubs/
009695399/basedefs/sys/stat.h.html
which says:
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.
and in the "Rationale" section they say:
"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

fix over/underflow issues in win32_msgwait
This commit does not completely fix 33096, since the real problem is that
VS IDE's debugger causes a Windows message to be sent to perl on each
breakpoint. Depending on where the breakpoint was set. The BP may make it
impossible to exit the loop because of the Visual Studio IDE Debugger's
design. Various overflow and underflow issues were fixed in win32_msgwait.
Specifically, the time count rolling forwards through zero
(GetSystemTimeAsFileTime), and the time count running ahead of the end
time (rolling backwards through zero) were fixed ("<=" check).

[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.

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.
