* Make Doxygen contented.

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()

* dbus/dbus-spawn.c: s/_exit/exit/ because it was keeping gcov
data from getting written, and there wasn't a good reason to
use _exit really.
* test/decode-gcov.c (mark_inside_dbus_build_tests): don't count
dbus_verbose lines in test coverage
(main): add list of functions sorted by # of untested blocks
to the coverage report
* dbus/dbus-mempool.c: put some test-only code in DBUS_BUILD_TESTS
* dbus/dbus-marshal.c (_dbus_marshal_test): extend test coverage
* dbus/dbus-message-handler.c (_dbus_message_handler_test):
extend test coverage
* test/data/auth/cancel.auth-script: test canceling an
authentication
* dbus/Makefile.am: remove dbus-server-debug.[hc] for now, as they
aren't used. in CVS history if we end up needing them.
|
|
* configure.in: add --enable-checks
* dbus/dbus-message.c (dbus_message_new): reverse name/service arguments
* dbus/dbus-connection.c (dbus_connection_preallocate_send): fix
to use thread locks.
(_dbus_connection_handler_destroyed_locked): move some private
functions into proper docs group
* dbus/dbus-internals.h: add _dbus_return_if_fail,
_dbus_return_val_if_fail
Throughout: use dbus_return_if_fail

|
* glib/dbus-gmain.c: adapt to watch changes
* bus/bus.c, bus/activation.c, etc.: adjust to watch changes
* dbus/dbus-server.h: remove dbus_server_handle_watch
* dbus/dbus-connection.h: remove dbus_connection_handle_watch
* dbus/dbus-watch.c (dbus_watch_handle): change DBusWatch to work
like DBusTimeout, so we don't need dbus_connection_handle_watch
etc.
|
|
* bus/dispatch.c (check_segfault_service_activation): add test
for launching an executable that just crashes.
* test/test-segfault.c (main): try setting coredumpsize to 0 so we
don't leave a million cores. We'll see how portable this is.
|
|
* dbus/dbus-spawn.c (_dbus_spawn_async_with_babysitter): move all
the possible parent failures before we fork, so that we don't
fail to create a babysitter after creating the child.
* bus/activation.c (bus_activation_activate_service): kill child
if we don't successfully complete the activation.
|
|
* dbus/dbus-connection.c (dbus_connection_flush): don't spin on
the connection if it's disconnected
* bus/activation.c (bus_activation_service_created): use new
transaction features to roll back removal of pending activation if
we don't successfully create the service after all. Don't remove
pending activation if the function fails.
* dbus/dbus-list.c (_dbus_list_insert_before_link)
(_dbus_list_insert_after_link): new code to facilitate
services.c fixes
* dbus/dbus-hash.c (_dbus_hash_table_insert_string_preallocated):
new functionality, so we can preallocate the ability to insert
into a hash table.
* bus/connection.c (bus_transaction_add_cancel_hook): new function
allowing us to put custom hooks in a transaction to be used for
cancelling said transaction
* doc/dbus-specification.sgml: add some discussion of secondary
service owners, and disallow zero-length service names
* bus/services.c (bus_registry_acquire_service): new function,
splits out part of bus_driver_handle_acquire_service() and fixes
a bug where we didn't remove the service doing the acquiring
from the secondary queue if we failed to remove the current owner
from the front of the queue.

* bus/bus.c (bus_context_new): fix wrong handling of
server_data_slot_unref() in the error case.
* dbus/dbus-internals.h (_dbus_assert): change so it passes
"(condition) != 0" to _dbus_real_assert so that
"_dbus_assert (pointer)" doesn't cause a warning
* bus/main.c (main): accept --print-address option to print out
the message bus address
* dbus/dbus-sysdeps.c (_dbus_generate_random_ascii): export this
* dbus/dbus-transport.c (_dbus_transport_open): special error for
"tmpdir" option to unix: address on client side
* dbus/dbus-server.c (dbus_server_listen): handle "tmpdir" option
to unix: address
* configure.in (TEST_SOCKET_DIR): locate a temporary directory
we can use to create sockets in the test suite.
* bus/main.c (signal_handler): on SIGTERM, exit the daemon
cleanly. To be used for testing.
* dbus/dbus-spawn.c (babysit): use _dbus_set_signal_handler()
* dbus/dbus-sysdeps.c (_dbus_set_signal_handler): new
* dbus/dbus-server-debug-pipe.c (_dbus_transport_debug_pipe_new):
handle trying to call this when there's no servers active
|
|
* dbus/dbus-string.c: docs warning
* dbus/dbus-spawn.c: missing docs
* dbus/dbus-memory.c (struct ShutdownClosure): missing docs
|
|
* bus/loop.c (bus_loop_iterate): fix the timeout code, using
magic from GLib
* dbus/dbus-spawn.c (_dbus_babysitter_unref): set sitter_pid
to -1 once we've reaped the babysitter
(_dbus_babysitter_handle_watch): do as much work as we can, not
just one go of it
* bus/activation.c: add code using DBusBabysitter so that we
handle it when a service fails to start up properly.
(bus_activation_service_created): don't remove the activation
entries as we go, just let them get removed when we free the pending
activation. Unref reply messages after sending them.
|
|
* dbus/dbus-spawn.c, dbus/dbus-spawn.h: Change dbus_spawn to
return a "babysitter" object that is used to monitor the status of
the spawned process and reap it when required.
* test/test-segfault.c, test/test-exit.c,
test/test-sleep-forever.c: binaries that do various lame things,
used in the test suite.
* dbus/dbus-sysdeps.c: kill _dbus_errno_to_string()
|
|
* dbus/dbus-spawn.c: Move dbus-spawn into a separate file
in preparation for modifying it, dbus-sysdeps is getting
a bit unmanageable.
