| | | | | | | | | | * bus/test.c (client_disconnect_handler): change to return HANDLED (would have been REMOVE_MESSAGE) * dbus/dbus-object.h (enum DBusHandlerResult): rename to HANDLED/NOT_YET_HANDLED instead of REMOVE_MESSAGE/ALLOW_MORE_HANDLERS to make it clearer how it should be used.

| | | | | | | | | | | | | | | | | | | | | | * tools/dbus-send.c (main): add --type argument, for now supporting only method_call and signal types. * tools/dbus-print-message.c: print message type * dbus/dbus-connection.c (_dbus_connection_new_for_transport): init connection->objects * doc/dbus-specification.sgml: fix sgml * bus/*.c: port over to object-instance API changes * test/test-service.c: ditto * dbus/dbus-message.c (dbus_message_create_header): allow #NULL name, we will have to fix up the rest of the code to also handle this (dbus_message_new): generic message-creation call (set_string_field): allow appending name field

| | | | | | | | * bus/config-parser.c (merge_included): merge in policies from child configuration file. * bus/policy.c (bus_policy_merge): function to merge two policies together

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * dbus/dbus-marshal.c (_dbus_marshal_validate_arg): fix to avoid calling _dbus_marshal_validate_arg() for every byte in a byte array, etc. * dbus/dbus-message-handler.c: use atomic reference counting to reduce number of locks slightly; the global lock in here sucks * dbus/dbus-connection.c (_dbus_connection_update_dispatch_status_and_unlock): variant of update_dispatch_status that can be called with lock held; then use in a couple places to reduce locking/unlocking (dbus_connection_send): hold the lock over the whole function instead of acquiring it twice. * dbus/dbus-timeout.c (_dbus_timeout_new): handle OOM * bus/connection.c (bus_connections_setup_connection): fix access to already-freed memory. * dbus/dbus-connection.c: keep a little cache of linked list nodes, to avoid using the global linked list alloc lock in the normal send-message case. Instead we just use the connection lock that we already have to take. * dbus/dbus-list.c (_dbus_list_find_last): new function * dbus/dbus-sysdeps.c (_dbus_atomic_inc, _dbus_atomic_dec): change to use a struct for the atomic type; fix docs, they return value before increment, not after increment. * dbus/dbus-string.c (_dbus_string_append_4_aligned) (_dbus_string_append_8_aligned): new functions to try to microoptimize this operation. (reallocate_for_length): break this out of set_length(), to improve profile info, and also so we can consider inlining the set_length() part. * dbus/dbus-message.c (dbus_message_new_empty_header): init data strings with some preallocation, cuts down on our calls to realloc a fair bit. Though if we can get the "move entire string to empty string" optimization below to kick in here, it would be better. * dbus/dbus-string.c (_dbus_string_move): just call _dbus_string_move_len (_dbus_string_move_len): add a special case for moving an entire string into an empty string; we can just swap the string data instead of doing any reallocs. (_dbus_string_init_preallocated): new function

Write a "test-profile" that does echo client-server with threads; profile reveals lock contention, memcpy/realloc of buffers, and UTF-8 validation as hot spots. 20% of lock contention eliminated with dbus_atomic_inc/dec implementation on x86. Much remaining contention is global mempool locks for GList and DBusList. * dbus/dbus-sysdeps.c (_dbus_atomic_inc, _dbus_atomic_dec): add x86 implementation * dbus/dbus-connection.c (struct DBusConnection): use dbus_atomic_t for the reference count * dbus/dbus-message.c (struct DBusMessage): declare dbus_atomic_t values as volatile * configure.in: code to detect ability to use atomic integer operations in assembly, from GLib patch * dbus/dbus-internals.c (_dbus_verbose_real): call getpid every time, tired of it being wrong in threads and forked processes * glib/test-profile.c: a little program to bounce messages back and forth between threads and eat CPU * dbus/dbus-connection.c: add debug spew macros for debugging thread locks; include config.h at top; fix deadlock in dbus_connection_flush()
