Corrects some message corruption issues. + + * dbus/dbus-mainloop.c: verbosity changes + + * dbus/dbus-keyring.c (_dbus_keyring_new_homedir): handle OOM + instead of aborting in one of the test codepaths + + * dbus/dbus-internals.c (_dbus_verbose_real): fix a bug that + caused not printing the pid ever again if a verbose was missing + the newline at the end + (_dbus_header_field_to_string): add HEADER_FIELD_SIGNATURE + + * dbus/dbus-connection.c: verbosity changes; + (dbus_connection_has_messages_to_send): new function + (_dbus_connection_message_sent): no longer call transport->messages_pending + (_dbus_connection_send_preallocated_unlocked): do one iteration to + try to write() immediately, so we can avoid the write watch. This + is the core purpose of this patchset + (_dbus_connection_get_dispatch_status_unlocked): if disconnected, + dump the outgoing message queue, so nobody will get confused + trying to send them or thinking stuff is pending to be sent + + * bus/test.c: verbosity changes + + * bus/driver.c: verbosity/assertion changes + + * bus/dispatch.c: a bunch of little tweaks to get it working again + because this patchset changes when/where you need to block. + 2004-11-23 Havoc Pennington <hp@redhat.com> * test/glib/test-profile.c: modify to accept a plain_sockets |
