--
It turned out that using the hash of the entire blob was not helpful.
Thus we redefine the Unique-Blob-ID (UBID) as the primary fingerprint
of the blob. In case this is a v5 OpenPGP key a left truncated
version of the SHA-256 hash is used; in all other cases the full SHA-1
hash. Using a SHA-256 hash does not make sense because v4 keys are
and will for some time be the majority of keys and thus padding them
with zeroes won't make any difference. Even if fingerprint collisions
can eventually be created we will assume that the keys are bogus and
that it does not make sense to store its twin also in our key storage.
We can also easily extend the update code to detect a collision and
reject the update.

that the datastream thread is only active while we are sending a

For Unix this basically syncs the code with what we have in gpg 1.4.
Note that xdg-open may not be used when running as root which we
support here.
For Windows we now use ShellExecute as this seems to be preferred over
"cmd /c start"; however this does not solve the actual problem we had
in the bug report. To solve that problem we resort to a wait
parameter which defaults to 400ms. This works on my Windows-10
virtualized test box. If we can figure out which simple viewers are
commonly installed on Windows we should enhance this patch to test for
them.

This generic caching module is better than the ad-hoc code we used in

start. There is also a small performance increase with the new cache:
With a large keyring and --list-sigs I get these numbers:
| | before | after |
|------+------------+------------|
| real | 14m1.028s | 12m16.186s |
| user | 2m18.484s | 1m36.040s |
| sys | 11m42.420s | 10m40.044s |
Note the speedup in the user time which is due to the improved cache
algorithm. This is obvious, because the old cache was just a long
linked list; the new cache are two hash tables.

The Web Key Directory should carry only one key. However, some

thunk that this is a good idea but I heard claims that this is needed
for them to migrate existing key data bases.
This patch puts a limit on 5 on it (we had none right now) and also
fixes the issue that gpg could not work immediately with the requested
key because the code uses the fingerprint of the key to use the
imported key. Now the first key is used. On a second try (w/o
accessing the WKD) the regular key selection mechanism would be in
effect. I think this is the most conservative approach. Let's see
whether it helps.

When importing an invalid secret key ring for example without key

secret keys anyway. This is clearly a bug because the diagnostics
before claimed that for example the subkeys have been skipped.
Importing the secret key parameters then anyway is surprising in
particular because a gpg -k does not show the key. After importing
the public key the secret keys suddenly showed up.

* g10/packet.h (struct revocation_key): Add field 'fprlen'.
* g10/parse-packet.c (parse_revkeys): Set fprlen and allow for v5
keys. Also fix reading of unitialized data at place where
MAX_FINGERPRINT_LEN is used.
* g10/revoke.c (gen_desig_revoke): Allow for v5 keys and use fprlen.
Do an explicit compare to avoid reading unitialized data.
* g10/sig-check.c (check_revocation_keys): Use the fprlen.
* g10/getkey.c (merge_selfsigs_main): Do an explicit copy to avoid

(menu_addrevoker): Use fprlen. Allow for v5 keys.
* g10/keygen.c (keygen_add_revkey): Use fprlen.
(parse_revocation_key): Allow for v5 keys.

better error message in case of bogus fingerprints.
* g10/keylist.c (print_revokers): Use fprlen.
--
The reading of uninitialized data is harmless but we better fix it to
make valgrind happy. More serious was that we always passed
MAX_FINGERPRINT_LEN but we will need to support 20 and 32 octet
fingerprints and MAX_FINGERPRINT_LEN would be too large for a v4.

Some stats: In the about 5300000 keys on the SKS servers we found 3055
unique mailboxes with a '+' in it. After removing leading and
trailing '+' as well as multiple '+' (e.g. "c++" or "foo+bar+baz")
2697 were left which seem to be valid sub-addresses.
To filter mailboxes out from a line delimited list with
user-ids (e.g. an SQL output), the command
t-mbox-util --verbose --filter
can be used; to output w/o sub-addresses add --no-sub.

--
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.
