2003-01-28  Havoc Pennington  <hp@pobox.com>

        * dbus/dbus-message.c (check_message_handling): function to check

        Invoke new message handlers.

        * dbus/dbus-list.h:
        Fix a typo in _dbus_list_get_prev_link, if we're at the first element we can't

        Add new messages, service flags and service replies.
        
2003-01-26  Havoc Pennington  <hp@pobox.com>

        * dbus/dbus-message-builder.c: implement, completely untested.

        * test/data/*: add data to be used in testing. 
        ".message" files are our simple loadable text format.
        ".message-raw" will be binary dumps of messages.

        * dbus/dbus-string.c (_dbus_string_starts_with_c_str): new

2003-01-26  Havoc Pennington  <hp@pobox.com>

        * dbus/dbus-sysdeps.c (_dbus_file_get_contents): new function

        * dbus/dbus-errors.c (dbus_result_to_string): add
        file errors

        * dbus/dbus-message-builder.c: new file, will contain code to load

2003-01-26  Havoc Pennington  <hp@pobox.com>

        * dbus/dbus-message.c (dbus_message_set_sender): support deleting
        the sender by setting to NULL

2003-01-26  Havoc Pennington  <hp@pobox.com>

        The unit tests pass, but otherwise untested.  If it breaks, the
        tests should have been better. ;-)
        
        * bus/driver.c (bus_driver_handle_hello): return if we disconnect
        the connection.

        * dbus/dbus-message.c: redo everything so we maintain 
        message->header as the only copy of the various fields.
        This avoids the possibility of out-of-memory in some cases,
        for example dbus_message_lock() can't run out of memory anymore,
        and avoids extra copying. Figured I may as well go ahead and do 
        this since it was busted for dbus_message_lock to not return 
        failure on OOM, and dbus_message_write_header was totally
        unchecked for OOM. Also fixed some random other bugs.

        * dbus/dbus-marshal.c (_dbus_marshal_get_field_end_pos): verify
        that strings are nul-terminated. Also, end_pos can be equal 
        to string length just not greater than, I think.
        (_dbus_marshal_set_int32): new function
        (_dbus_marshal_set_uint32): new function
        (_dbus_marshal_set_string): new function

        * dbus/dbus-connection.c (_dbus_connection_new_for_transport): fix
        a warning, init timeout_list to NULL
        (dbus_connection_send_message): don't use uninitialized variable
        "serial"

        * dbus/dbus-string.c (_dbus_string_replace_len): new function

2003-01-26  Anders Carlsson  <andersca@codefactory.se>

        * bus/driver.c: (bus_driver_handle_hello),
        (bus_driver_send_welcome_message):
        Plug leaks
        
2003-01-26  Anders Carlsson  <andersca@codefactory.se>

        * dbus/dbus-auth.c: (process_auth), (_dbus_auth_unref):
        * dbus/dbus-connection.c: (_dbus_connection_new_for_transport),
        (dbus_connection_unref):
        * dbus/dbus-marshal.c: (_dbus_marshal_test):
        * dbus/dbus-message.c: (dbus_message_unref),
        Plug memory leaks.
        
        (dbus_message_get_fields): 
        Remove debugging printout.

        (_dbus_message_loader_return_buffer):
        Don't store the header string.
        
        (_dbus_message_test):
        Plug leaks.

2003-01-26  Richard Hult  <rhult@codefactory.se>

        * glib/dbus-gmain.c (dbus_connection_dispatch): Traverse a copy of
        the file descriptor list, since it can change under us.

2003-01-25  Anders Carlsson  <andersca@codefactory.se>

        * glib/dbus-gmain.c: (dbus_connection_prepare),
        (dbus_connection_check), (dbus_connection_dispatch), (add_watch),
        (remove_watch), (dbus_connection_hookup_with_g_main):
        Rewrite the glib handling to use its own GSource instead of a 
        GIOChannel so we can catch messages put in the queue while waiting
        for a reply.
        
2003-01-25  Anders Carlsson  <andersca@codefactory.se>

        * bus/Makefile.am:

        * bus/dispatch.h:
        * bus/driver.c: (bus_driver_send_service_deleted),
        (bus_driver_send_service_created), (bus_driver_handle_hello),
        (bus_driver_send_welcome_message),
        (bus_driver_handle_list_services), (bus_driver_remove_connection),
        (bus_driver_handle_message):
        * bus/driver.h:
        Refactor code, put the message dispatching in its own file. Use 
        _DBUS_HANDLE_OOM. Also send ServiceDeleted messages when a client
        is disconnected.
        
2003-01-25  Anders Carlsson  <andersca@codefactory.se>

        * dbus/dbus-internals.h:
        Add _DBUS_HANDLE_OOM macro, it doesn't do anything currently.
        
        * dbus/dbus-message.c: (dbus_message_get_sender):
        * dbus/dbus-message.h:
        Implement dbus_message_get_sender.
        
        * dbus/dbus-protocol.h:
        Add message and service defines.

        Building --disable-verbose-mode --disable-asserts --disable-tests
        cuts the library from 112K to 45K or so
        
        * configure.in: check for varargs macro support, 
        add --enable-verbose-mode, --enable-asserts.

        * dbus/dbus-test.c: include config.h so that tests actually run

        * dbus/dbus-string.c: add assertions that stuff is 8-byte aligned,
        so the failure mode when that assumption fails will be plenty
        obvious.

2003-01-18  Havoc Pennington  <hp@pobox.com>

        * configure.in: default --enable-tests to $USE_MAINTAINER_MODE

        * dbus/Makefile.am: fix it up so dubs-test-main.c is included in
        the distribution

        * test/Makefile.am: don't use special variable "TESTS" for echo-*
        since we don't want to use those in make check

2003-01-15  Havoc Pennington  <hp@redhat.com>

        Release 0.2
        
        * NEWS: update

        * bus/main.c: (main):
        Make sure that the DBusConnectionData struct is NULLed
        out to prevent a segfault.
        
        * dbus/dbus-errors.c: (dbus_result_to_string):
        * dbus/dbus-errors.h:
        * dbus/dbus-message.c: (dbus_message_get_fields),
        (dbus_message_get_fields_valist), (_dbus_message_test):
        * dbus/dbus-message.h:
        Make dbus_message_get_fields return a result code so we can
        track invalid fields as well as oom.
        
2003-01-11  Havoc Pennington  <hp@pobox.com>

        * configure.in: change --enable-test/--enable-ansi action-if-given
        to enable_foo=$enableval instead of enable_foo=yes

2003-01-08  Havoc Pennington  <hp@pobox.com>

        * dbus/dbus-string.c (_dbus_string_align_length): new function

        * dbus/dbus-test-main.c: move main() for test app here
        * dbus/dbus-test.c
        (dbus_internal_symbol_do_not_use_run_tests): we have to export a
        symbol to run tests, because dbus-test isn't in the main 
        library

        Code review nitpicks.
        
        * dbus/dbus-message.c (dbus_message_write_header): add newlines
        for people with narrow emacs ;-). Assert client_serial was filled
        in. Assert message->name != NULL.
        (dbus_message_append_fields): have "first_field_type" arg separate
        from va list, needed for C++ binding that also uses varargs IIRC
        and helps with type safety
        (dbus_message_new): add @todo about using DBusString to store
        service/name internally
        (dbus_message_new): don't leak ->service and ->name on OOM later
        in the function
        (dbus_message_unref): free the service name
        (dbus_message_get_fields): same change to varargs
        i.e. first_field_type
        (_dbus_message_loader_return_buffer): assert that the message data
        is aligned (if not it's a bug in our code). Put in verbose griping
        about why we set corrupted = TRUE.
        (decode_header_data): add FIXME that char* is evil.  Was going to
        add FIXME about evil locale-specific string.h strncmp, but just
        switched to wacky string-as-uint32 optimization. Move check for
        "no room for field name" above get_const_data_len() to avoid
        assertion failure in get_const_data_len if we have trailing 2
        bytes or the like. Check for service and name fields being
        provided twice. Don't leak service/name on error. Require field
        names to be aligned to 4 bytes.

        * dbus/dbus-marshal.c: move byte swap stuff to header
        (_dbus_pack_int32): uscore-prefix

        handling allowing corrupt data to go unchecked

2003-01-08  Havoc Pennington  <hp@redhat.com>

        * dbus/dbus-transport-unix.c (unix_do_iteration): add read/write 
        to the select() as needed for authentication. (should be using
        _dbus_poll() not select, but for another day)

        * dbus/dbus.h: include dbus/dbus-protocol.h

2003-01-08  Anders Carlsson  <andersca@codefactory.se>

        * test/watch.c (error_handler): make it safe if the error handler

        handler/ we should just guarantee it's called only once)

        * dbus/dbus-transport.c (_dbus_transport_disconnect): call the
        error handler on disconnect (it's quite possible we should
        just change the error handler to a "disconnect handler," I'm

        WORDS_BIGENDIAN then compiler byte order is DBUS_BIG_ENDIAN,
        doh

        * dbus/dbus-marshal.c: Add macros to do int swapping in-place and
        avoid swap_bytes() overhead (ignoring possible assembly stuff for 
        now). Main point is because I wanted unpack_uint32 to implement
        _dbus_verbose_bytes
        (_dbus_verbose_bytes): new function

        * dbus/dbus-string.c (_dbus_string_validate_ascii): new function

        leak reference count in no-message case

        * test/watch.c (do_mainloop): handle adding/removing watches
        during iteration over the watches. Also, ref the connection/server
        stored on a watch, so we don't try to mangle a destroyed one.

        * dbus/dbus-transport.c (_dbus_transport_init_base): create 
        the auth conversation DBusAuth

        * dbus/dbus-transport-unix.c (_dbus_transport_new_for_fd)
        (_dbus_transport_new_for_domain_socket): when creating a
        transport, pass in whether it's a client-side or server-side
        transport so we know which DBusAuth to create

        * dbus/dbus-transport-unix.c (unix_finalize): finalize base
        _after_ finalizing the derived members
        (unix_connection_set): unref watch if we fail to add it

        * dbus/dbus-connection.c (dbus_connection_unref): delete the
        transport first, so that the connection owned by the 
        transport will be valid as the transport finalizes.

        if necessary, and remove watches from the connection.

        Add string marshal functions and have the demarshal functions
        return the new position.
        
2002-12-25  Havoc Pennington  <hp@pobox.com>

        * doc/dbus-sasl-profile.txt: docs on the authentication protocol, 
        it is a simple protocol that just maps directly to SASL.

        * dbus/dbus-auth.h, dbus/dbus-auth.c: authentication protocol
        initial implementation, not actually used yet.

        * glib/dbus-gthread.c: fix include

        * glib/dbus-glib.h: rename DBusMessageHandler for now. 
        I think glib API needs to change, though, as you don't 
        want to use DBusMessageFunction, you want to use the 
        DBusMessageHandler object. Probably 
        dbus_connection_open_with_g_main_loop()
        and dbus_connection_setup_g_main_loop() or something like that
        (but think of better names...) that just create a connection 
        that has watch/timeout functions etc. already set up.

        * dbus/dbus-connection.c
        (dbus_connection_send_message_with_reply): new function just to 
        show how the message handler helps us deal with replies.

        (rebuild_table): be more paranoid about overflow, and 
        shrink table when we can
        (_dbus_hash_test): reduce number of sprintfs and write
        valid C89. Add tests for case where we grow and then 
        shrink the hash table.

        * dbus/dbus-mempool.h, dbus/dbus-mempool.c: memory pools

        * dbus/dbus-connection.c (dbus_connection_register_handler) 
        (dbus_connection_unregister_handler): new functions

        * dbus/dbus-message.c (dbus_message_get_name): new

        (dbus_connection_gsource_new):
        * glib/dbus-gthread.c: (dbus_gmutex_new), (dbus_gmutex_free),
        (dbus_gmutex_lock), (dbus_gmutex_unlock), (dbus_gthread_init):
        * glib/test-dbus-glib.c: (message_handler), (main):
        Add GLib support.

        without make install.

2002-12-15  Havoc Pennington  <hp@pobox.com>

        * dbus/dbus-threads.c: add thread stubs that a higher library
        layer can fill in. e.g. the GLib wrapper might fill them in with
        GThread stuff. We still need to use this thread API to
        thread-safe-ize the library.

2002-12-12  Havoc Pennington  <hp@pobox.com>

        * dbus/dbus-transport-unix.c, dbus/dbus-server-unix.c: use the

        * dbus/dbus-connection.c: include dbus-message-internal.h

        * HACKING: add file with coding guidelines stuff.

        * dbus/dbus-string.h, dbus/dbus-string.c: Encapsulate all string
        handling here, for security purposes (as in vsftpd). Not actually
        using this class yet.

        * dbus/dbus-sysdeps.h, dbus/dbus-sysdeps.c: Encapsulate all
        system/libc usage here, as in vsftpd, for ease of auditing (and
        should also simplify portability). Haven't actually moved all the
        system/libc usage into here yet.
        
2002-11-25  Havoc Pennington  <hp@pobox.com>

        * dbus/dbus-internals.c (_dbus_verbose): fix to not 
        always print the first verbose message.

        * test/echo-client.c, test/echo-server.c: cheesy test

        representing a server that listens for connections.

        * dbus/.cvsignore: create

        * dbus/dbus-errors.h, dbus/dbus-errors.c:

        public object representing a connection that 
        sends/receives messages. (Same object used for 
        both client and server.)

        * dbus/dbus-transport.h, dbus/dbus-transport.c:
        Basic abstraction for different kinds of stream
        that we might read/write messages from.

2002-11-23  Havoc Pennington  <hp@pobox.com>

        * dbus/dbus-internals.h (_DBUS_INT_MAX): add _DBUS_INT_MIN

        array sometimes.

        * Doxyfile.in (INCLUDE_FILE_PATTERNS): expand DBUS_BEGIN_DECLS/
        DBUS_END_DECLS to nothing, that should fix this once and for all

        * Doxyfile.in (JAVADOC_AUTOBRIEF): set to YES

        * dbus/dbus-message.c, dbus/dbus-hash.c: 
        add some missing @brief

2002-11-23  Havoc Pennington  <hp@pobox.com>

        * dbus/dbus-message.h: put semicolons after DEBUG_BEGIN_DECLS 
        to avoid confusing Doxygen

        * dbus/dbus-hash.c: @} not }@

        * dbus/dbus-message.c (struct DBusMessage): split out 
        internals docs

        * configure.in: pile on more warning flags if using gcc

        * Doxyfile.in (EXTRACT_STATIC): set to NO, so we don't have 
        to document static functions

        * configure.in: add summary to end of configure so it 
        looks nice and attractive

        * dbus/dbus-hash.c: finish implementation and write unit 
        tests and docs

        * configure.in: add --enable-tests to enable unit tests

        * dbus/dbus-test.c: test program to run unit tests 
        for all files in dbus/*, initially runs a test for 
        dbus-hash.c
        
        * dbus/dbus-internals.h: file to hold some internal utility stuff

2002-11-22  Havoc Pennington  <hp@redhat.com>

        * dbus/dbus-hash.c: copy in Tcl hash table, not yet 
        "ported" away from Tcl

2002-11-22  Havoc Pennington  <hp@redhat.com>

        * dbus/dbus.h: fixups for doc warnings

        * dbus/dbus-message.c: move inline docs into .c file

        * Doxyfile (OUTPUT_DIRECTORY): move output to doc/api
        so all docs are under doc/
        (MAN_EXTENSION): generate man pages. Use extension 
        ".3dbus" which matches ".3qt" on my system, 
        I guess this is OK, I don't know really.
        (FILE_PATTERNS): look for .c files not .h, makes sense
        for plain C I think

2002-11-22  Havoc Pennington  <hp@pobox.com>

        * Makefile.am (SUBDIRS): rename subdir "server" to "bus" 
        because any app can be a server, and any app can be a client, 
        the bus is a special kind of server.

Thu Nov 21 23:35:31 2002  Zack Rusin  <zack@kde.org>

        * Doxyfile : adding. Still needs Makefile rules to be generated
        automatically (just run "doxygen" in the toplevel dir for now to
        generate docs)
        
        * dbus/dbus-message.h : Adding sample docs (javadoc since
        resembles gtk-doc a little more)

        * dbus/dbus.h : Adding sample docs

2002-11-21  Havoc Pennington  <hp@redhat.com>

        * dbus/Makefile.am (INCLUDES): define DBUS_COMPILATION 
        so we can allow ourselves to include files directly, 
        instead of having to use dbus.h

        * dbus/dbus.h: fill in

        * dbus/dbus-message.h: sketch out a sample header file.
        Include griping if you include it directly instead of 
        via dbus.h

        * dbus/dbus-macros.h: new file with macros for extern "C", 
        TRUE/FALSE, NULL, etc.

        * doc/file-boilerplate.c: put include guards in here

2002-11-21  Havoc Pennington  <hp@redhat.com>

        * autogen.sh (run_configure): add --no-configure option
