More complete handling of padlists for XSUBs.
[Code by Zefram, commit message by Nicholas]
Following discussion with Zefram on IRC, I agree that his code is more
correct than mine. Prior to the use of the CvPADLIST slot on an XSUB for
binary incompatibility detection, cv_undef() would unconditionally treat
CvPADLIST() as a pointer to a padlist structure (on both PVCVs and PVFMs),
walking it and calling the relevant free functions. Hence on those versions,
CvPADLIST could not be anything other than a legitimate padlist, else the
interpreter would crash. So we should be consistent and calculate the size
on the same basis.

Count the size of padlist names in CVs (for v5.18 and later).

A more robust test for the size of subroutines in packages which import.
A test in t/recurse.t broke because Test::More::is() had been refactored.
Obviously that wasn't correct. Ultimately the problem was because the test
as-was wasn't minimally testing the thing that it was intended to test. It
should be now. Comments in the test explain the problem.
Reported as CPAN #102910.

reading tied scalar shrinks it
One of Devel-Size's tests, for a tied scalar visibly growing when the
underlying tie object grows, is failing on Perl 5.19.3 because an earlier
read of the scalar clears its PV buffer, causing the scalar to shrink.
Attached patch makes the test allow for such shrinkage.

wrong test for magicalness
Devel::Size looks at the SvMAGIC pointer for any SV that's SVt_PVMG or above.
This is incorrect. It is actually necessary (and sufficient) to check the
SvMAGICAL flag. Attached patch fixes.

An alternative test that CvOUTSIDE is being followed.
As of v5.17.2, CvOUTSIDE is NULL on cloned closures, unless they contain a
string eval. Hence the size of closures should differ, as long as Size.xs
is correctly following CvOUTSIDE.

Test that we can measure that recursion increases the size of the PADLIST.
Nicholas Clark [Fri, 10 May 2013 07:25:13 +0000]
Stubbed subs no longer have CvOUTSIDE set.
t/code.t was testing whether Devel::Size was following CvOUTSIDE by relying
on the implementation detail that CvOUTSIDE is set for a subroutine that is
explicitly stubbed, and not set for one that is implicitly stubbed at runtime.
v5.17.0 changed the compile-time behaviour so that no stubbed subroutine has
CvOUTSIDE set, which breaks the assumption of this test. Hence change the test
to verify the new behaviour. However, this leaves us currently with no test
for CvOUTSIDE.
(Based on a patch by Zefram. see RT #83903 and perl's commit
8be227ab5eaa23f2)
Zefram [Fri, 10 May 2013 07:09:58 +0000]
Don't follow CvSTART() if CvROOT() is NULL.
For v5.17.2, blead switched to a slab allocator for OPs. During subroutine
compilation, the CV's slab is held in CvSTART(), to avoid extending every
PVCV by one more pointer. Once compilation is complete, the optree slab
pointer becomes accessible at an offset from CvROOT(), and CvSTART() is
set to point to the first OP. However, in some cases, PVCVs in the incomplete
state can become visible to Devel::Size, for example by following the
CvOUTSIDE() from BEGIN blocks. So we need to ignore CvSTART() if CvROOT() is
NULL. (Arguably we should always ignore CvSTART(), as the OP that it points to
should be accessible somewhere in the tree referenced by CvROOT(), but that
change can wait for a later date)
