"clean", and add "minimize".
* import.c (parse_import_options): Make help text match the export
versions of the options.
* options.h, export.c (parse_export_options, do_export_stream): Reduce
clean options to two: clean and minimize.
* trustdb.h, trustdb.c (clean_one_uid): New function that joins uid
and sig cleaning into one for a simple API outside trustdb.
cleaning from one convenient place.
* options.h, import.c (parse_import_options, clean_sigs_from_all_uids,
import_one): Reduce clean options to two: clean and minimize.
* parse-packet.c (setup_user_id): Remove. (parse_user_id,
parse_attribute): Just use xmalloc_clear instead.
non-selfsigs from key during cleaning. Change all callers.
* export.c (do_export_stream): Use it here so we don't need additional
minimize code in the export path.
speaking this should be only in gpg_CPPFLAGS, but then we have to
compile everything twice for gpg and gpgv.
* apdu.c (open_pcsc_reader): Fix double free.
* gpg.c (main) [__APPLE__]: Default the PCSC driver to the OS X
location. Suggested by Patty A. Hardy.
so keyserver mangled keys with doubled user IDs can be properly
cleaned - possibly sigs on the different user IDs cancel each other
out.
* import.c (parse_import_options), export.c (parse_export_options):
List "xxx-clean" before the longer options so we don't end up with a
partial match on the longer options.
* trustdb.c (clean_uids_from_key): Return proper number of cleaned
user IDs. Don't count user IDs as cleaned unless we actually delete
something.
keygen.c (make_backsig): Did some backsig interop testing with the PGP
folks. All is well, so I'm turning generation of backsigs on for new
keys. Checking for backsigs on verification is still off.
parse_attribute_subpkts): Make a number of warnings verbose items.
These fire on many slightly mangled keys in the field, so the
warning is becoming burdensome.
algorithms.
* keyedit.c (sign_uids): Don't request a signing key to make a
certification.
* keygen.c (do_add_key_flags): Force the certify flag on for all
primary keys, as the spec requires primary keys must be able to
certify (if nothing else, which key is going to issue the user ID
signature?) (print_key_flags): Show certify flag. (ask_key_flags,
ask_algo): Don't allow setting the C flag for subkeys.
* keyid.c (usagestr_from_pk), getkey.c (parse_key_usage): Distinguish
between a sign/certify key and a certify-only key.
* main.h, misc.c (path_access): New. Same as access() but does a PATH
search like execlp.
* keyserver.c (curl_can_handle): Removed. Replaced by...
(curl_cant_handle): We are now relying on curl as the handler of last
resort. This is necessary because PGP LDAP and curl LDAP are apples
and oranges. (keyserver_typemap): Only test for ldap and ldaps.
(keyserver_spawn): If a given handler is unusable (as determined by
path_access()) then try gpgkeys_curl.
