--
A little drawback of that code is that if the WKD has no update for an
expired key each access of the key will trigger a WKD lookup (unless
cached by the dirmngr). To avoid this we need to record the last time
we have checked for an update but that would in turn require that we
update the keyring for each check. We defer this until we have a
better key database which allows for fast updates of meta data.
Testing the code is currently a bit cumbersome because it requires to
update a key in the WKD several times. Eventually we we need a
network emulation layer to provide sample data for the regression
tests.

Note that this function extends the "rvs" field signature-class (field

A new field is added to the "rvs" (and in future also the "rev")
record to carry a record specific comment. Hopefully all parsers
meanwhile learned the lesson from other new fields and don't bail out
on more fields than they know about.

* g10/key-check.c (sig_comparison): Take care of HELP_COUNTER.
(key_check_all_keysigs): De-duplicate on a per-block base.
--
The key_check_all_keysigs first does a detection of duplicate
signature. This is done over all signatures at once. The problem
here is for example:
key
uid_1
sig_uid_1.1
sig_uid_1.2
subkey_1
sig_sub_1.1
subkey_2
sig_sub_2.1
sig_sub_2.2 (duplicate of sig_sub_1.1)
Now the de-duplication deletes the first signature and keeps the
second. That works in most cases for foreign signature on userids but
in the above constellation the code simply removes sig_sub_1.1 so that
subkey_1 has no binding signature anymore. In a later step during
import the missing binding is detected and subkey_1 is removed because
it is not anymore valid. The sig_sub_2.2 will also be removed later
because it does not check out for subkey_2 (that is as expected).
The fix is to let the de-duplication work only on blocks (ie. within
the signatures of a user id or a subkey). This will not detect all
duplicates but that does not harm because later steps will detect and
remove them.
In the above case (with this patch applied) the second phase of
key_check_all_keysigs will reorder key signatures and move the
duplicate sig_sub_2.2 directly after sig_sub_1.1. This duplicates the
signature and for cleanness we should kick the de-duplication process
again. This will be done with a followup patch.
