the documentation was updated to specify a void return value, but
SvUPGRADE() was left always returning 1 for backwards compatibility. This
has now been removed, and SvUPGRADE() is now a statement with no return

Eliminate the fifth argument from GDBM_File::TIEHASH.
This was intended to provide control of the callback used by gdbm* functions
in case of fatal errors (such as filesystem problems), but did not work (and
could never have worked). No code on CPAN even attempted to use it. The
callback is now always the previous default, croak.
This eliminates the only used of 'FATALFUNC' in the *DBM modules' type
files, so remove it from all of them.
It also eliminates a cast from a data pointer to a function pointer, which
is not legal C, and rightly upsets pedantic ANSI C compilers. The fact that
there was exactly cast, and only in one direction, gives a clue as to how
likely this was ever to work.
Nicholas Clark [Thu, 13 Dec 2012 15:38:17 +0000 (16:38 +0100)]
GDBM_File is meant to croak() if the gdbm library has a fatal error.
gdbm_open() takes a fifth argument, for an optional callback function used
to report a fatal error. Since it was added in 5.000, the tied hash wrapper
implemented in GDBM_File.xs has (intended) to default this to croak().
However, the callback expects a function taking a single const char *
argument, whereas croak(const char *pat, ...) has variable arguments.
The code as-was had two bugs
1) The calling ABI on some platforms differs between a (known) variable-
argument function, and one which takes (known) fixed arguments. As the
call site knows the pointer is to a function with fixed arguments, the
calling convention it uses doesn't match what Perl_croak_nocontext()
expects, which can lead to crashes.
2) A message containing % characters will be interpreted as a printf format.
Both these are fixed by using a small station function as a wrapper, which
takes a single string argument, and passes to croak() a "%s" format string,
followed by the string for the error message.
Add a test for this functionality.

have been had sv type restrictions since probably day 1 and for
performance reason. Anyone who hit the restrictions would have either
fixed their code immediately, or abandoned using XS. I observed someone
abandoning XS in the field over these undocumented restrictions.

Really fix t/op/lex.t

Copy keys for aassign in lvalue sub
Checking LVRET (which pp_aassign does, as of a few commits ago)
has no effect if OPpMAYBE_LVSUB is not set on the op. This com-
mit changes op.c:op_lvalue_flags to set this flag on aassign ops.
This makes sub:lvalue{%h=($x,$x)} behave correctly if the return
values of the sub are assigned to ($x is unmodfied).

pp_hot.c:pp_aassign: mortalise variable only if we have to
This affects the hash-assignment path.
Don’t mortalise the value to protect it from a magical key making the
hv_store_ent call die, as that could unduly extend the mortals stack.
Instead, copy the key if it is magical.
Based on a patch by Ruslan Zakirov.

don't create a copy of keys if it's not LVALUE context
Making another copy slows things down. We can avoid it
if aassign is not expected to return LVALUEs.

refactor aassign
move populating stack with return values. Place it
into main loop right after we stored values.
This allow us to delete special if blocks for
hash/array on LHS followed by other hash/array.
Also, clearing HV out of ENTER/LEAVE block is bad -
segfaults in corner cases.
Don't use goto for odd elements case.
store undef on stack for odd case. we can avoid NULL
checks in the loop and use assert like array assignment
does.
use SvSETMAGIC rather than repeate what it means.
for array and hash assignment "while (relem <= SP)" loop
at the end was always empty. Put it into else branch.

ary/hash/firsthashelem should be set only once
Only once for first hash or array, otherwise
(%h,@a) = ... assignment returns wrong results
for duplicates and/or number of elements on RHS.
