(g13_components): New variable. (main_sources): Add $(g13_components). * g13.c, engine-g13.c: New files. * engine.c (engine_ops): Check for assuan for assuan engine, add g13 engine. * util.h (_gpgme_get_g13_path, _gpgme_encode_percent_string): New prototypes. * conversion.c (_gpgme_encode_percent_string): New function. * gpgme.h.in (gpgme_protocol_t): Add GPGME_PROTOCOL_G13. (struct _gpgme_op_g13_result, gpgme_g13_result_t): New types. (gpgme_op_g13_mount): New function. * gpgme.def, libgpgme.vers: Add gpgme_op_g13_mount. * gpgme.c (gpgme_set_protocol): Allow GPGME_PROTOCOL_G13. (gpgme_get_protocol_name): Add GPGME_PROTOCOL_G13. * posix-util.c (_gpgme_get_g13_path): New function. * w32-util.c (_gpgme_get_g13_path): New function. * engine-backend.h (_gpgme_engine_ops_g13): New declaration. --- ChangeLog | 4 + NEWS | 13 +- configure.ac | 125 +++++++ src/ChangeLog | 21 ++ src/Makefile.am | 18 +- src/conversion.c | 69 ++++ src/engine-assuan.c | 2 + src/engine-backend.h | 8 +- src/engine-g13.c | 796 +++++++++++++++++++++++++++++++++++++++++++ src/engine.c | 12 +- src/g13.c | 229 +++++++++++++ src/gpgme.c | 6 +- src/gpgme.def | 2 + src/gpgme.h.in | 26 +- src/libgpgme.vers | 2 + src/posix-util.c | 10 + src/util.h | 4 + src/w32-util.c | 19 ++ 18 files changed, 1346 insertions(+), 20 deletions(-) create mode 100644 src/engine-g13.c create mode 100644 src/g13.c diff --git a/ChangeLog b/ChangeLog index ff98830..fc92fa1 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,7 @@ +2009-10-22 Marcus Brinkmann + + * configure.ac: Add support for G13. + 2009-10-20 Marcus Brinkmann * configure.ac (AC_CONFIG_FILES): Remove assuan/Makefile. diff --git a/NEWS b/NEWS index f22e197..58e91f6 100644 --- a/NEWS +++ b/NEWS @@ -6,11 +6,16 @@ Noteworthy changes in version 1.2.1 (unreleased) application programmers on systems that can resolve inter-library dependencies at runtime, this is a transparent change. + * New engine GPGME_PROTOCOL_G13 to support the new g13 tool. + * Interface changes relative to the 1.2.0 release: - ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - GPGME_STATUS_INV_SGNR NEW. - GPGME_STATUS_NO_SGNR NEW. - ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +GPGME_STATUS_INV_SGNR NEW +GPGME_STATUS_NO_SGNR NEW +GPGME_PROTOCOL_G13 NEW +gpgme_op_g13_mount NEW +gpgme_g13_result_t NEW +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Noteworthy changes in version 1.2.0 (2009-06-18) ------------------------------------------------ diff --git a/configure.ac b/configure.ac index e685628..44eb5ed 100644 --- a/configure.ac +++ b/configure.ac @@ -120,6 +120,7 @@ AM_CONDITIONAL(HAVE_LD_VERSION_SCRIPT, test "$have_ld_version_script" = "yes") GPG_DEFAULT=no GPGSM_DEFAULT=no GPGCONF_DEFAULT=no +G13_DEFAULT=no component_system=None have_dosish_system=no have_w32_system=no @@ -133,6 +134,7 @@ case "${host}" in GPG_DEFAULT='c:\\gnupg\\gpg.exe' GPGSM_DEFAULT='c:\\gnupg\\gpgsm.exe' GPGCONF_DEFAULT='c:\\gnupg\\gpgconf.exe' + G13_DEFAULT='c:\\gnupg\\g13.exe' #component_system='COM+' AM_PATH_GLIB_2_0 @@ -166,6 +168,7 @@ case "${host}" in # GPG_DEFAULT='/usr/bin/gpg' # GPGSM_DEFAULT='/usr/bin/gpgsm' # GPGCONF_DEFAULT='/usr/bin/gpgconf' +# G13_DEFAULT='/usr/bin/g13' ;;
