Subject: New -list function added to bleeding. -list=format-methods
This will list all 'non-default' (i.e. methods which have been overridden),
within each format.
The syntax is --list=format-methds[=WHICH]
If WHICH is filled in, then only formats which have that function defined
will be listed. So --list=format-methods=clear_keys will list only
formats that have a clear_keys pointer that is not fmt_default_clear_keys.
NOTE, set_key, get_key, crypt_all, cmp_all, cmp_one, cmp_exact are ALWAYS
forced to be set, there are no defaults. Thus those always get printed.
One other 'feature', is the code will also print if any of the get_hash or
binary_hash function pointers are null. The format self test code fails
for any format for any of the other pointers IF they are null, so I did not
replicate that code here.
I do notice that quite a few formats have NULL get_hash / binary_hash
pointers, so this will likely generate some patches soon :^) as maintainers
can start looking at the big picture of the formats. I notice that all
'thin' dynamic formats have both of these arrays of pointers NULL (but
should not), so I have to dig into the linkage code, and see what is busted.
Jim.
