* tests/fdpassing.c: Update to new API. * configure.ac: Check for stdint.h and inttypes.h. Invoke AC_TYPE_UINTPTR_T. doc/ 2009-09-21 Marcus Brinkmann <[email protected]> * assuan.texi: Update to new API. src/ 2009-09-19 Marcus Brinkmann <[email protected]> * src/libassuan.vers, src/libassuan.def: Update to new API. * assuan.c, context.c, system.c, debug.c: New files. * Makefile.am (common_sources): Add assuan.c, context.c, system.c and debug.c. * assuan.h: Include <stdarg.h>. Fix inclusion of <gpg-error.h>. (_ASSUAN_EXT_SYM_PREFIX, _ASSUAN_PREFIX1, _ASSUAN_PREFIX2) (_ASSUAN_PREFIX): Remove support for renaming the whole library, now that we have a stable shared library interface that can evolve to cover all needs (particularly those of GPGME). (assuan_malloc_hooks, assuan_malloc_hooks_t, assuan_log_cb_t) (assuan_io_monitor_t): New types. (ASSUAN_LOG_INIT, ASSUAN_LOG_CTX, ASSUAN_LOG_ENGINE) (ASSUAN_LOG_DATA, ASSUAN_LOG_SYSIO, ASSUAN_IO_FROM_PEER) (ASSUAN_IO_TO_PEER, ASSUAN_IO_MONITOR_NOLOG) (ASSUAN_IO_MONITOR_IGNORE): New symbols. (assuan_set_gpg_err_source, assuan_get_gpg_err_source) (assuan_get_malloc_hooks, assuan_set_log_cb, assuan_get_log_cb) (assuan_new, assuan_new_ext, assuan_release): New function prototypes. (assuan_init_pipe_server, assuan_init_socket_server) (assuan_init_socket_server_ext, assuan_pipe_connect) (assuan_pipe_connect_ext, assuan_socket_connect) (assuan_socket_connect_ext): Take a context argument instead of pointer to context. (assuan_deinit_server, assuan_disconnect) (assuan_set_assuan_err_source): Remove function prototypes. * assuan-defs.h (ASSUAN_GCC_A_PURE): Moved here from XXX (_assuan_error): New macro. (struct assuan_context_s): New members err_source, w32_strerror, malloc_hooks, log_cb, log_cb_data: New members. Move confidential into flags. New member engine. (_assuan_log_handler, _assuan_error_default, _assuan_disconnect): New prototypes. (_assuan_new_context): Remove prototype. (_assuan_malloc, _assuan_calloc, _assuan_realloc, _assuan_free): Add context argument to prototype. * assuan-util.c (alloc_func, realloc_func, free_func): Remove global variables. (assuan_set_malloc_hooks, _assuan_malloc, _assuan_realloc) (_assuan_calloc, _assuan_free, assuan_set_pointer) (assuan_get_pointer, assuan_begin_confidential) (assuan_end_confidential, assuan_set_io_monitor, assuan_set_flag) (assuan_get_flag): Move functions to ... * assuan-client.c: Add ctx argument to all invocations of _assuan_error. * assuan-socket-server.c, assuan-socket-connect.c, assuan-connect.c: Likewise. * assuan-buffer.c: Likewise. Also update access to confidential flag. * assuan-uds.c: Add ctx argument to all invocations of _assuan_malloc, _assuan_realloc, _assuan_calloc, _assuan_free and _assuan_error. * assuan_listen.c, assuan-inquire.c, assuan-handler.c: Likewise. * assuan-error.c (err_source): Remove global variable. (assuan_set_assuan_err_source): Removed function. (_assuan_w32_strerror): Moved here from assuan-logging.c and made thread-safe. (_assuan_error): Removed function (is now macro). * assuan-handler.c: Update access to confidential flag. * assuan-socket-server.c (accept_connection_bottom): Update access to confidential flag in context. (assuan_init_socket_server, assuan_init_socket_server_ext): Take ctx argument instead of pointer to ctx. * assuan-inquire.c (init_membuf, put_membuf, get_membuf) (free_membuf): Take context argument and change all callers. * assuan-socket-server.c (assuan_socket_connect) (assuan_socket_connect_ext): Take ctx argument instead of pointer to ctx. * assuan-pipe-connect.c (initial_handshake, pipe_connect_unix) (socketpair_connect, assuan_pipe_connect) (assuan_pipe_connect_ext): Likewise. (socketpair_connect): Now that ctx is not a pointer argument anymore, return if we are server or client in the argv argument. * assuan-logging.c (_assuan_log_handler): New function. (_assuan_w32_strerror): Move to assuan-error.c * assuan-connect.c (assuan_disconnect): Renamed to ... (_assuan_disconnect): ... this. * assuan-pipe-server.c (_assuan_new_context): Removed function. (assuan_init_pipe_server): Take ctx argument instead of pointer to ctx. (_assuan_release_context): Removed function. (_assuan_deinit_server): Reimplement.
