From a2129f7cccaf0265fffe0da79ca0510b6e01131b Mon Sep 17 00:00:00 2001 From: Havoc Pennington Date: Sun, 1 Oct 2006 15:36:19 +0000 Subject: 2006-10-01 Havoc Pennington * dbus/dbus-connection.c (_dbus_connection_close_if_only_one_ref): Add a hack to make DBusNewConnectionFunction work right. * dbus/dbus-server-socket.c (handle_new_client_fd_and_unlock): use the hack here. Also, fix the todo about refcount leak. * dbus/dbus-server-debug-pipe.c (_dbus_transport_debug_pipe_new): and use the hack here * dbus/dbus-connection.c: Kill the "shared" flag vs. the "shareable" flag; this was completely broken, since it meant dbus_connection_open() returned a connection of unknown shared-ness. Now, we always hold a ref on anything opened as shareable. Move the call to notify dbus-bus.c into connection_forget_shared_unlocked, so libdbus consistently forgets all its knowledge of a connection at once. This exposed numerous places where things were totally broken if we dropped a ref inside get_dispatch_status_unlocked where connection_forget_shared_unlocked was previously, so move connection_forget_shared_unlocked into _dbus_connection_update_dispatch_status_and_unlock. Also move the exit_on_disconnect here. (shared_connections_shutdown): this assumed weak refs to the shared connections; since we have strong refs now, the assertion was failing and stuff was left in the hash. Fix it to close still-open shared connections. * bus/dispatch.c: fixup to use dbus_connection_open_private on the debug pipe connections * dbus/dbus-connection.c (dbus_connection_dispatch): only notify dbus-bus.c if the closed connection is in fact shared (_dbus_connection_close_possibly_shared): rename from _dbus_connection_close_internal (dbus_connection_close, dbus_connection_open, dbus_connection_open_private): Improve docs to explain the deal with when you should close or unref or both * dbus/dbus-bus.c (_dbus_bus_notify_shared_connection_disconnected_unlocked): rename from _dbus_bus_check_connection_and_unref_unlocked and modify to loop over all connections * test/test-utils.c (test_connection_shutdown): don't try to close shared connections. * test/name-test/test-threads-init.c (main): fix warnings in here * dbus/dbus-sysdeps.c (_dbus_abort): support DBUS_BLOCK_ON_ABORT env variable to cause blocking waiting for gdb; drop DBUS_PRINT_BACKTRACE and just call _dbus_print_backtrace() unconditionally. * configure.in: add -export-dynamic to libtool flags if assertions enabled so _dbus_print_backtrace works. * dbus/dbus-sysdeps-unix.c (_dbus_print_backtrace): use fprintf instead of _dbus_verbose to print the backtrace, and diagnose lack of -rdynamic/-export-dynamic --- ChangeLog | 65 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 65 insertions(+) (limited to 'ChangeLog') diff --git a/ChangeLog b/ChangeLog index fbba11a7..b2bd8dda 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,68 @@ +2006-10-01 Havoc Pennington + + * dbus/dbus-connection.c (_dbus_connection_close_if_only_one_ref): + Add a hack to make DBusNewConnectionFunction work right. + + * dbus/dbus-server-socket.c (handle_new_client_fd_and_unlock): use + the hack here.
