each() should not leave RITER set on empty hash
Commit
900ac0519e (5.11.0) sped up keys() on an empty hash by modify-
ing the iteration code not to loop through the buckets looking for an
entry if the number of keys is 0. Interestingly, it had no visible
affect on keys(), but it *did* have one on each(). Resetting the ite-
rator’s current bucket number (RITER) used to be done inside that loop
in hv_iternext. keys() always begins by resetting the iterator, so it
was unaffected. But each %empty will leave the iterator as-is. It
will be set on an empty hash if the last element was deleted while an
iterator was active. This has buggy side-effects.
$h{1} = 2;
each %h; # returns (1, 2)
delete $h{1};
each %h; # returns false; should reset iterator
$h{1}=2;
print each %h, "\n"; # prints nothing
Commit
3b37eb248 (5.15.0), which changed the way S_hfreeentries works.
(S_hfreentries is called by all operators that empty hashes, such as
%h=() and undef %h.) Now S_hfreentries does nothing if the hash is
empty. That change on its own should have been harmless, but the
result was that even %h=() won’t reset RITER after each() has put
things in an inconsistent state. This caused test failures in
Text::Tabulate.
So the solution, of course, is to complete the change made by
900ac0519e and reset the iterator properly in hv_iternext if the
hash is empty.

Hide pad vars from magic methods on scope exit
If, during scope exit, a pad var is being cleared for reuse, it needs
to be hidden from magic methods that might reference it through weak

Weak refs to pad hvs should go stale
When a lexical variable goes out of scope, as in
{
my %lexical_variable;
...
}
# no longer in scope here
it is supposed to disappear as far as Perl code can tell. That the
same SV is reused the next time that scope is entered is an implement-
ation detail.
The move of hashes’ back-references from magic into the HvAUX struc-
ture in 5.10 caused this implementation detail to leak through.
Normally, weak references to pad variables going out of scope are
killed off:
{
my $scalar;
weaken ($global_scalar = \$scalar);
}
# here $global_scalar is undef
When hashes’ back-references were moved, leave_scope was not updated
to account. (For non-hash variables, it’s the mg_free call that takes
care of it.) So in this case:
{
my %hash;
weaken ($global_scalar = \%hash);
}
$global_scalar would still reference a hash, but one marked PADSTALE.
Modifications to that hash through the reference would be visible the
next time the scope was entered.

Stop @{""} = reverse @_ from crashing
Class::ClassDecorator was crashing during compilation on this line:
@{"$name\::ISA"} = ( reverse @_ );
I presume this was due to commit
540dd770, which changed the way the
inplace-reverse optimisation is activated, because the crash happens
in S_inplace_aassign. But deleting even one line of code here or
there makes the crash go away (hence the lack of tests).
This is my reasoning for how this commit eliminates the crash:
@{""} = reverse @_
compiles down to
b <2> aassign[t5] vKS/COMMON ->c
- <1> ex-list lK ->8
3 <0> pushmark s ->4
7 <@> reverse[t4] lK/1 ->8
4 <0> pushmark s ->5
6 <1> rv2av[t3] lK/1 ->7
5 <#> gv[*_] s ->6
- <1> ex-list lK ->b
8 <0> pushmark s ->9
a <1> rv2av[t1] lKRM*/1 ->b
- <@> scope sK ->a
- <0> ex-nextstate v ->9
9 <$> const[PV ""] s ->a
Notice that the second rv2av does not have an a gv op as its child,
but a scope instead.
In S_inplace_aassign, which checks to see whether the optimisation is
even possible, oleft refers to the second rv2av above (with scope as
its child; i.e., @{""}) while oright refers to the first rv2av (with
gv as its child; @_).
This check to make sure the left side is an array
/* Check the lhs is an array */
if (!oleft ||
(oleft->op_type != OP_RV2AV && oleft->op_type != OP_PADAV)
|| oleft->op_sibling
|| (oleft->op_private & OPpLVAL_INTRO)
)
return;
does not check the op type of the rv2av’s child.
So this check, a little further on, to see whether the arrays are the
same on both sides (which applies only to rv2av; padav is handled
further on):
/* check the array is the same on both sides */
if (oleft->op_type == OP_RV2AV) {
if (oright->op_type != OP_RV2AV
|| !cUNOPx(oright)->op_first
|| cUNOPx(oright)->op_first->op_type != OP_GV
|| cGVOPx_gv(cUNOPx(oleft)->op_first) !=
cGVOPx_gv(cUNOPx(oright)->op_first)
)
return;
assumes that cUNOPx(oleft)->op_first is a gv op.
That is not the case when the lhs is @{""}, so
cGVOPx_gv(some_scope_op) ends up trying to read
((PADOP*)some_scope_op)->op_padix under threaded perls, passing
that ‘index’ (which is actually the scope op’s op_first field) to
PAD_SV[...], consequently reading past the end of the pad and possibly
into unallocated territory; hence the crash.

Document File::Glob’s :bsd_glob tag
Father Chrysostomos [Sat, 29 Oct 2011 07:02:01 +0000 (00:02 -0700)]
Add :bsd_glob export tag to File::Glob [perl #96116]
This is intended to replace the :glob export tag. The problem with
:glob is that the glob export (File::Glob::glob) does not support ite-
ration, but tries to return a whole list each time; hence it causes
while(<*>) to loop endlessly, as it is repeatedly returning the last
file (scalar context).
Since there may be code relying on that, we cannot easily change it,
but we can supplant it.
Since bsd_glob is already documented as supporting spaces in patterns
(that match spaces in file names; i.e., that are not separators), this
commit adds a :bsd_glob export tag that only differs from :glob in
that the exported glob() function iterates in scalar context.
An imminent commit will add documentation.

Make csh_glob remove quote-escaping backslashes
This commit does not change the output on Unix. On Windows, where the
globbing engine does not usually treat backslashes as escapes, this
restores the behaviour to what it was before commit
0b0e6d70, for
cases like glob('a\"b c\"d').
Before
0b0e6d70, the preprocessing done by csh_glob (which it out-
sourced to Text::ParseWords) would remove backslash escapes, so the
globbing engine got to see a"b and c"d.
Since
0b0e6d70, the backslash escapes were no longer removed (because
in most cases they needed to remain, to avoid backslashitis), so the
globbing engine got to see a\"b and c\"d. On Unix that made no dif-
ference, as the globbing engine treats \ as an escape character. But
on Windows it doesn’t usually, so the output changed and produced a
literal a\"b.
This commit strips out quote-escaping backslashes in the prepro-
cessing code.
