We currently don't skip keys if the search mode is
KEYDB_SEARCH_MODE_FIRST. Since we change KEYDB_SEARCH_MODE_FIRST to
KEYDB_SEARCH_MODE_NEXT (to avoid a reset), it only makes sense to have
the same semantics for KEYDB_SEARCH_MODE_NEXT.

The keybox code doesn't work directly with keyblocks. As such, the
matched user packet is not readily available to pass to
DESC[n].SKIPFNC. But, we do know the index of the user id packet that
matched. Thus, pass that instead. If the skip function needs the
user id packet, it can use the key id to look up the key block and
find the appropriate packet.

Note that although PKA is now always build, it will only work if
support for looking up via DNS has not been disabled.
The new PKA only works with the IPGP DNS certtype and shall be used
only to retrieve the fingerprint and optional the key for the first
time. Due to the security problems with DNSSEC the former assumption
to validate the key using DNSSEC is not anymore justified. Instead an
additional layer (e.g. Trust-On-First-Use) needs to be implemented to
track change to the key. Having a solid way of getting a key matching
a mail address is however a must have.
More work needs to go into a redefinition of the --verify-options
pka-lookups and pka-trust-increase. The auto-key-locate mechanism
should also be able to continue key fetching with another methods once
the fingerprint has been retrieved with PKA.

Needed for unattended key edits with --status-fd, because since 2.1
status prompts are preceded by es_fflush (in cpr.c:do_get_from_fd)
not fflush(3), so the standard output may not be flushed before each
prompt. (Which breaks scripts using select(2) to multiplex between
the standard and status outputs.)
His patch only affected print_and_check_one_sig_colon() but there are
many more places where stdio and estream are mixed. This patch now
replaces most of them in g10/. At some places stdio is still used,
but that is local to a function and should not have side effects.

some of them will need to be kept (maybe changed with an indication to

This patch separates Libgcrypt and OpenPGP public key algorithms ids
and in most cases completely removes the Libgcrypt ones. This is
useful because for Libgcrypt we specify the algorithm in the
S-expressions and the public key ids are not anymore needed.
This patch also adds some support for PUBKEY_ALGO_EDDSA which will
eventually be used instead of merging EdDSA with ECDSA. As of now an
experimental algorithm id is used but the plan is to write an I-D so
that we can get a new id from the IETF. Note that EdDSA (Ed25519)
does not yet work and that more changes are required.
The ECC support is still broken right now. Needs to be fixed.

We do not want to use the default capabilities (derived from the

--
Import and key listing does now work with the keybox format. It is
still quite slow and signature caching is completely missing.
Increasing the maximum allowed length for a keyblock was required due
to a 700k keyblock which inhibited kbxutil to list the file.
kbxutil's option name --import-openpgp is not quite appropriate
because it only creates KBX blobs from OpenPGP data.
The asymmetric quotes used by GNU in the past (`...') don't render
nicely on modern systems. We now use two \x27 characters ('...').
The proper solution would be to use the correct Unicode symmetric
quotes here. However this has the disadvantage that the system
requires Unicode support. We don't want that today. If Unicode is
available a generated po file can be used to output proper quotes. A
simple sed script like the one used for en@quote is sufficient to
change them.
The changes have been done by applying
sed -i "s/\`\([^'\`]*\)'/'\1'/g"
to most files and fixing obvious problems by hand. The msgid strings in
the po files were fixed with a similar command.
Returning -1 as an error code is not very clean given that gpg error
has more descriptive error codes. Thus we now return
GPG_ERR_NOT_FOUND for all search operations and adjusted all callers.
Since 2009-12-08 gpg was not able to find email addresses indicated
by a leading '<'. This happened when I merged the user id
classification code of gpgsm and gpg.
We better do this once and for all instead of cluttering all future
commits with diffs of trailing white spaces. In the majority of cases
blank or single lines are affected and thus this change won't disturb
a git blame too much. For future commits the pre-commit scripts
checks that this won't happen again.
