 OTHER CORE CHANGES

Subject: Bug in debugger with import manipulations
Date: Mon, 23 Dec 1996 05:37:48 -0500 (EST)
From: Ilya Zakharevich <ilya@math.ohio-state.edu>
Files: pp_hot.c

    Finally I traced why MakeMaker runs wrongly under debugger: debugger
    function calling sequence was assuming that
    	GvCV(CvGV(cv)) == cv
    for non-anonymous subs (ne END). MakeMaker managed to break it by
    	*A::B = \&C::D;
    	eval 'sub C::D {new one}';
    
    After this CvGV(\&A::B) is *C::D, but &{*C::D} is the "new one".
    
    Patch follows (note that in this case we do not sacrifice having a
    subroutine name in debugger output ;-).
    
    Enjoy,

Subject: Import and dynamic methods
Date: Mon, 23 Dec 1996 01:45:37 -0500 (EST)
From: Ilya Zakharevich <ilya@math.ohio-state.edu>
Files: gv.c hv.c sv.c

    Here is the patch which corrects bad things which happens when you
    import subroutines and otherwise manipulate the symbol tree.
    
    I put forward the only chunk which may be controversal, since it may
    have a minor performance penalty. It is independent of the others, so
    it can be freely deleted.
    
    The manipulations which correctly propagate to method calls:
    	a) Pruning globs:		delete $B::{method}
    	b) Undefing subroutines:	undef &B::method;
    	c) Importing:			*B::method = \&mymethod;
    
    Enjoy,

Subject: sv_gets patch
Date: Sun, 22 Dec 1996 03:24:04 -0500 (EST)
From: Ilya Zakharevich <ilya@math.ohio-state.edu>
Files: pp_hot.c

    I sent this patch before as a part of 
    	pos $str =
    	$str = /failing/g
    patch. Now I separate it in the case it was tainted by environment:
    
    Synopsis:
    	$a = <FH>;
    does not work as expected if $a is magic (say, tied).
    
    Enjoy,

Subject: pos $str patch
Date: Sun, 22 Dec 1996 03:31:21 -0500 (EST)
From: Ilya Zakharevich <ilya@math.ohio-state.edu>
Files: mg.c pp_hot.c t/op/pat.t

    This patch was (mostly) posted already.
    
    It fixes the bug:
    	pos $str 
    is reset to undef if
    	$str =~ /failing/g
    fails.
    
    Additionally, if fixes the hidded bit (=MGf_MINMATCH) surviving
    setting 
    	pos $str = ...
    
    Enjoy,
