Refactor unpack’s newDEFSVOP logic; correct prototype
unpack is the only op that takes an implicit $_ for its second argu-
ment. (For others it’s the first.)
Instead of special-casing unpack with its own ck_ routine, we can sim-
ply modify the logic in ck_fun to apply OA_DEFGV to the first optional
argument, not just the first argument.
Currently OA_DEFGV is not set in PL_opargs[OP_UNPACK], which means the
automatically-generated prototype is ($;$), instead of ($_).
This commit sets the flag on the op, changes it to use ck_fun
directly, and updates ck_fun and the prototype-generation code accord-
ingly. I couldn’t put this in multiple commits, as the changes are
interdependent.

[perl #97020] Carp (actually caller) leaking memory
Commit
eff7e72c3 (Detect incomplete caller overrides in Carp) used
this little trick for detecting a @DB::args that an overridden
caller() failed to set:
+ @args = \$i; # A sentinal, which no-one else has the address of
But there is a bug in caller(). The first time caller tries to write
to @DB::args, it calls Perl_init_dbargs first. That function checks
whether @DB::args is AvREAL, in case someone has assigned to it, and
takes appropriate measures. But caller doesn’t bother calling
Perl_init_dbargs more than once. So manually-assigned items in
@DB::args would leak, starting with the *second* call to caller.
Commit
eff7e72c3 triggered that bug, resulting in a regression in
Carp, in that it started leaking.
eff7e72c3 was backported to 5.12.2
with commit
97705941a4, so in both 5.12 and 5.14 Carp is affected.
This bug (the caller bug, not Carp’s triggering thereof) also affects
any caller overrides that set @DB::args themselves, if there are
alternate calls to the overridden caller and CORE::caller.
This commit fixes that by changing the if (!PL_dbargs) condition
in pp_caller to if (!PL_dbargs || AvREAL(PL_dbargs)). I.e., if
@args is either uninitialised or AvREAL then call Perl_init_dbargs.
Perl_init_dbargs also has a bug in it, that this fixes: The array not
only needs AvREAL turned off, but also AvREIFY turned on, so that
assignments to it that occur after its initialisation turn AvREAL back
on again. (In fact, Larry Wall added a comment suggesting this back
in perl 5.000.)

&CORE::foo() for nullary functions
This commit makes nullary subs in the CORE package callable with
ampersand syntax and through references--except for wantarray, which
is more complicated and will have its own commit.
It does this by creating an op tree like this:
$ ./perl -Ilib -MO=Concise,CORE::times -e 'BEGIN{\&CORE::times}'
CORE::times:
3 <1> leavesub[1 ref] K/REFC,1 ->(end)
- <@> lineseq K ->3
1 <$> coreargs(IV 310) v ->2
2 <0> tms ->3
-e syntax OK
The coreargs op checks to make sure there are no arguments, for now.
The 310 is the op number for times (OP_TMS).
There is no nextstate op, because we want to inherit hints from
the caller.
The __FILE__, __LINE__ and __PACKAGE__ directives are implemented
like this:
$ ./perl -Ilib -MO=Concise,CORE::__FILE__ -e 'BEGIN{\&CORE::__FILE__}'
CORE::__FILE__:
7 <1> leavesub[1 ref] K/REFC,1 ->(end)

[perl #96126] Allocate CvFILE more simply
See the thread starting at:
http://www.nntp.perl.org/group/perl.perl5.porters/2011/07/msg175161.html
Instead of assuming that only Perl subs have mallocked CvFILEs and
only under threads, resulting in various hackery to borrow parts of
the SvPVX buffer where that assumption proves wrong, we can simply
add another flag (DYNFILE) to indicate whether CvFILE is mallocked,
instead of trying to use the ISXSUB flag for two purposes.
This simplifies the code greatly, eliminating bug #96126 in the pro-
cess (which had to do with sv_dup not knowing about the hackery that
this commit removes).
I removed that comment from cv_ckproto_len about CONSTSUBs doubling up
the buffer field, as it is no longer relevant. But I still left the
code as it is, since it’s better to do an explicit length check.

commit
eb796c7f1a47acbd996034731639c1bb76e31a19
Author: Gerard Goossen <gerard@ggoossen.net>
Date: Tue Aug 9 20:35:06 2011 +0200
Move bareword checking from the peephole optimizer to finalize_optree. Fixes [perl #95998]
The bareword checking is moved from the peephole optimizer to finalize_optree.
newRANGE needs additional bareword checking because the constants may
be optimized away by 'gen_constant_list'.
The OPpCONST_STRICT flag is removed after giving an error about a
bareword to prevent giving multiple errors about the same bareword.
In some cases, like pipe(foo,bar), the bareword was subject to strict
'subs' even though it was meant to be exempt.
A backtrace revealed that it happened in S_finalize_op when called
recursively from this block:
#if defined(PERL_MAD) && defined(USE_ITHREADS)
{
/* Make sure mad ops are also thread-safe */
MADPROP *mp = o->op_madprop;
while (mp) {
if (mp->mad_type == MAD_OP && mp->mad_vlen) {
OP *prop_op = (OP *) mp->mad_val;
/* We only need "Relocate sv to the pad for thread safety.", but this
easiest way to make sure it traverses everything */
finalize_op(prop_op);
}
mp = mp->mad_next;
}
}
#endif
That comment about only needing to relocate the sv to the pad is
telling. If that’s the only reason for the recursive call, then
we don’t want that recursive call doing strict checking. So this
commit simply turns off the strict flag, which should be safe, since
S_no_bareword_allowed does the same thing itself.

Make lock(&foo) syntax nominally lock the subroutine
In 5.10, lock(&foo) was an error for non-lvalue subs. For lvalue
subs, it passed &foo to the lockhook and return \&foo.
In 5.12, lock(&foo) was still an error for non-lvalue subs. For
lvalue subs, it would pass &foo to the lockhook and then either
trip an assertion (-DDEBUGGING) or return &foo, resulting in inter-
esting bugs.
Commit
f4df43b5e changed lock(&lvalue_sub) to call the sub and lock
its return value.
As Reini Urban pointed out in
<CAHiT=DE5cVZbuCR3kb=Q5oCa18vo3jr5jZKmURHYha2PwF4pEQ@mail.gmail.com>,
locking a subroutine does have its uses.
Since lock(&foo) has never really worked anyway, we can still
change this.
So, for lvalue subs, this reverts back to the 5.10 behaviour. For
non-lvalue subs, it now behaves the same way, the lvalue flag making
no difference. Note that it still causes an error at run-time, if
threads::shared is loaded, as its lockhook is conservative in what
it accepts.
But this change allows for future extensibility, unlike
f4df43b5e.
A note about the implementation: There are two pieces of code (at
least) in op.c that convert an entersub op into an rv2cv, one in
S_doref and the other in Perl_op_lvalue_flags. Originally (before
f4df43b5e) it was S_doref that took care of that for OP_LOCK. But
Perl_op_lvalue_flags is called first, so it would assume it was an
assignment to a sub call and croak if there was no lvalue sub in the
symbol table. This commit adds back the special case for OP_LOCK, but
in Perl_op_lvalue_flags, not S_doref.

Move pp_-specific code out of core_prototype
Commit
b8c38f0a2a65 refactored pp_prototype by moving much of its
code to a new function in op.c, called core_prototype. This served
two purposes: (1) to allow the code to be simplified, which required
the use of static functions in op.c, and (2) to allow the &CORE::subs
feature to share the same code.
But some code was moved to core_prototype which, in hindsight, did not
need to be moved, such as the ‘Can’t find an opnumber’ message.
This commit moves that code back to pp_prototype, resulting in a sim-
pler (and possibly faster, at least for &CORE::subs) core_prototype.

Change core_prototype to take a keyword num
This refactoring requires the caller to provide the keyword
number to core_prototype. Consequently, it speeds up the code in
gv.c:gv_fetchpvn_flags by allowing it to avoid an extra call to
keyword().
This takes the place of the len parameter, which is no longer used.
It used to be used only as an argument to keyword(). Since the code
that uses strEQ is only reached if the keyword has already been veri-
fied by keyword(), the name simply cannot have embedded nulls, so len
is not necessary.

Add tests for precedence of CORE:: subs
Father Chrysostomos [Sat, 6 Aug 2011 07:20:06 +0000 (00:20 -0700)]
Add inlinable &CORE::functions
This commit allows this to work:
BEGIN { *entangle = \&CORE::tie };
entangle $foo, $package;
And the entangle call gets inlined as a tie op, the resulting op tree
being indistinguishable.
These subs are not yet callable via &foo syntax or through a refer-
ence. That will come later, except for some functions, like sort(),
which will probably never support it.
Almost all overridable functions are supported. These few are not:
- infix operators
- not and getprotobynumber (can’t get the precedence right yet;
prototype problem)
- dump
Subsequent commits (hopefully!) will deal with those.
How this works:
gv_fetchpvn_flags is extended with hooks to create subs inside the
CORE package. Those subs are XSUBs (whose C function dies with an
error, for now at least) with a call checker that blows away the
entersub op and replaces it with whatever op the sub represents.
This is slightly inefficient right now, as gv_fetchpvn_flags calls
keyword(), only to have core_prototype call it again. That will
be fixed in a future refactoring.
Father Chrysostomos [Tue, 2 Aug 2011 22:04:47 +0000 (15:04 -0700)]
Make core_prototype provide the op number as well
Since it has to calculate it, it might as well provide it, so callers
do not have to go through that while(i < MAXO) loop yet again.
(The &CORE::foo feature will use this.)
Father Chrysostomos [Tue, 2 Aug 2011 21:46:17 +0000 (14:46 -0700)]
Make sure the CORE package is always called CORE
And not ::CORE or main::CORE or *CORE, etc.
Since the CORE package’s magic for autovivifying CORE subs
will be based on the package name, we can’t have code like
&::CORE::foo breaking the entire package.
Making a more general change to gv_fetchpvn_flags causes
problems for autoloaded SUPER methods and strangely-named
packages like main::::foo, so this patch is CORE-specific.

Remove select’s prototype
select has a prototype of (;*), which is incorrect, as it implied that
it has high precedence. It also fails to account for the four-argu-
ment form. While removing all incorrect prototypes is counterproduc-
tive, I think this one is wrong enough it deserves to go. (And the
precedence problem is a good argument against it, as there is cur-
rently no other way to set precedence.)

Initial attempt at putting podcheck.t on a diet.
The current design of this test is to scan *every* file in a dirty
build directory to see if it contains POD, excluding only a short
list of files and file types that it knows about. This means that
on most platforms it was scanning executable code, object code,
object libraries, dynamic libraries, and many other build products
too numerous to mention.
The present commit expands the exclusion list considerably and
makes that list slightly more cross-platform, but it's probably
still quite incomplete. Whether that list is even worth
maintaining or the test should be based on an inclusion list
rather than an exclusion list is a question worth asking.
On my system, the present austerity measures, despite the addition
of Config, reduce memory consumption by 14% (but it's still a pig,
gulping something like 160MB). Physical I/O is reduced by 105%
and elapsed time by 25%.

Trim trailing dots on VMS in podcheck.t.
readdir() and thus File::Find return files having zero-length
extensions as 'foo.' which doesn't match entries like 'foo' in
the known problems database. Trimming that trailing dot reduces
the number of failures on VMS to a handful. They are primarily
due to:
1.) The test attempts to exclude .PL files, but on VMS, case is
not preserved by default, so these appear as .pl and are not
excluded, confusing a number of the tests.
2.) Utilities and scripts are built with a .com extension on VMS,
but the corresponding entries in the known problems database have
no extension, so they don't match.

Clean up MANIFEST before creating a new one.
This is a follow-up to

appending to an existing MANIFEST to creating a new one. On VMS,
that would give us multiple versions, which probably wouldn't
matter except that the tests insist that there is one and only
one copy of every file they've created and they only clean up the
highest version.
The easiest way to handle this is to make sure we clean up first
before creating a new MANIFEST file.

Change (l)stat’s prototype from * to ;*

This commit accomplishes that by setting the OA_OPTIONAL flag for the

else, as ck_ftst (the check routine for [l]stat) doesn’t even look at

It also has to tweak the prototype-generation logic slightly, because
PL_opargs also has OA_DEFGV set.

Revert "[perl #95550] Remove prototypes from (l)stat"
It turns out this problem is more knotty than I initially realised.
stat had a prototype of (*), even though it could be called with no
arguments. Since the (*) prototype does not parse its argument the
same way that stat parses *its* argument, I thought that changing (*)
to (;*) would be no better, since it’s still not correct. So I simply
set the prototype to undef.
My thinking was faulty, for two reasons:
• The prototype serves to indicate the precedence, not just the types
of arguments. An undefined prototype on an overridable prefix func-
tion implies that it takes a list. So this causes problems for the
imminent &CORE::subs feature, as there is not yet a clean mechanism
for CVs to parse their arguments.
• The (*) prototype character does not parse the same way as *any*
built-in function with that character in its prototype. So stat is
no worse than any other built-in. It doesn’t make sense to remove
the prototype from stat without removing it from about 40 other
built-in functions; and that’s where pedantry conflicts with
usefulness.
This commit restores the (*) prototype to stat and lstat. The next
commit will give it a (;*) prototype, as that matches it more closely.
It’s not perfect, but it’s no worse that other built-ins with a * in
their prototypes.
