From a1f76b3b54b75a150fe272b804d85ffd40a507a6 Mon Sep 17 00:00:00 2001 From: Werner Koch Date: Tue, 17 Apr 2018 08:33:44 +0200 Subject: core: Add extended versions of the encrypt functions. * src/gpgme.h.in (gpgme_op_encrypt_ext_start) New. (gpgme_op_encrypt_ext): New. (gpgme_op_encrypt_sign_ext_start): New. (gpgme_op_encrypt_sign_ext): New. * src/libgpgme.vers, tests/run-encrypt.c: Add them. * src/encrypt.c (encrypt_start): Add arg recpstring. (gpgme_op_encrypt): Factor code out to ... (gpgme_op_encrypt_ext): new function with new arg recpstring. (gpgme_op_encrypt_start): Factor code out to ... (gpgme_op_encrypt_ext_start): new function with new arg recpstring. * src/encrypt-sign.c (encrypt_sign_start): Add arg recpstring. (gpgme_op_encrypt_sign): Factor code out to ... (gpgme_op_encrypt_sign_ext): new function with new arg recpstring. (gpgme_op_encrypt_sign_start): Factor code out to ... (gpgme_op_encrypt_sign_ext_start): new function with new arg recpstring. * src/engine-backend.h (struct engine_ops): Change fields encrypt and encrypt_sign. * src/engine.c (_gpgme_engine_op_encrypt): Add arg recpstring and pass to engine. (_gpgme_engine_op_encrypt_sign): Ditto. * src/engine-gpg.c (append_args_from_recipients_string): New. (gpg_encrypt): Add arg recpstring and call new function as needed. (gpg_encrypt_sign): Ditto. * src/engine-gpgsm.c (set_recipients_from_string): New. (gpgsm_encrypt): Add arg recpstring and call new function as needed. * src/engine-uiserver.c (set_recipients_from_string): New. (uiserver_encrypt): Add arg recpstring and call new function as needed. * tests/run-encrypt.c (xstrdup): New. (main): Add option --keystring. * src/gpgme-json.c (get_keys): Simplify. (op_encrypt): Modify to make use of the extended encrypt function. -- This new feature can be used to avoid the need for a key lookup and thus several extra calls to the backend. Note that run-test uses a semicolon as delimiter because that make testing the feature on the command line much easier.
