* bus/bus.c (process_config_every_time): Drop existing conf-dir
watches (if applicable) and add new watches
* bus/main.c (signal_handler): Handle SIGIO if using D_NOTIFY
(main): Setup SIGIO signal handler if using D_NOTIFY
* bus/config-parser.h: Add prototype bus_config_parser_get_conf_dirs
* bus/config-parser.c (struct BusConfigParser): Add conf_dirs list
(merge_included): Also merge conf_dirs list
(bus_config_parser_unref): Clear conf_dirs list
(include_dir): Add directory to conf_dirs list
(bus_config_parser_get_conf_dirs): New function
* bus/dir-watch.[ch]: New files
* bus/Makefile.am (BUS_SOURCES): Add dir-watch.[ch]
* configure.in: Add checks for D_NOTIFY on Linux
* bus/bus.c (load_config): Break into three
separate functions: process_config_first_time_only,
process_config_every_time, and process_config_postinit.
(process_config_every_time): Move call of
bus_registry_set_service_context_table into
process_config_postinit.
(process_config_postinit): New function, does
any processing that needs to happen late
in initialization (and also on reload).
(bus_context_new): Instead of calling load_config,
open config parser here and call process_config_first_time_only
and process_config_every_time directly. Later, after
we have forked but before changing UID,
invoke bus_selinux_full_init, and then call
process_config_postinit.
(bus_context_reload_config): As in bus_context_new,
load parse file inside here, and call process_config_every_time
and process_config_postinit.
* bus/services.h, bus/services.c
(bus_registry_set_service_context_table): Rename
from bus_registry_set_sid_table. Take string hash from config
parser, and convert them here into SIDs.
* bus/config-parser.c (struct BusConfigParser): Have
config parser only store a mapping of service->context
string.
(merge_service_context_hash): New function.
(merge_included): Merge context string hashes instead
of using bus_selinux_id_table_union.
(bus_config_parser_new): Don't use bus_selinux_id_table_new;
simply create a new string hash.
(bus_config_parser_unref): Unref it.
(start_selinux_child): Simply insert strings into hash,
don't call bus_selinux_id_table_copy_over.
* bus/selinux.h, bus/selinux.c (bus_selinux_id_table_union)
(bus_selinux_id_table_copy_over): Delete.
* bus/selinux.c (bus_selinux_init): Split into two functions,
bus_selinux_pre_init and bus_selinux_post_init.
(bus_selinux_pre_init): Just determine whether SELinux is
enabled.
(bus_selinux_post_init): Do everything else.
* bus/main.c (main): Call bus_selinux_pre_init before parsing
config file, and bus_selinux_post_init after. This ensures that
we don't lose the policyreload notification thread that
bus_selinux_init created before forking previously.
* bus/test-main.c (test_pre_hook): Update for split.
DBusError that was causing a memoy leak (bug #989).
* dbus/dbus-keyring.c, dbus/dbus-message.c: fix compilation on
Solaris/Forte C (bug #974)
* bus/main.c (main): plug two minuscule memleaks.
SELinux support from Matthew Rickard <mjricka@epoch.ncsc.mil>

functionality

* bus/policy.c (bus_policy_merge): add FIXME to a comment
* bus/main.c (main): initialize and shut down selinux
* bus/connection.c: store SELinux ID on each connection, to avoid
repeated getting of the string context and converting it into
an ID
* bus/bus.c (bus_context_get_policy): new accessor, though it
isn't used
(bus_context_check_security_policy): check whether the security
context of sender connection can send to the security context of
recipient connection
* bus/config-parser.c: add parsing for <selinux> and <associate>
* dbus/dbus-transport.c (_dbus_transport_get_unix_fd): to
implement dbus_connection_get_unix_fd()
* dbus/dbus-connection.c (dbus_connection_get_unix_fd): new
function, used by the selinux stuff
* bus/main.c (setup_reload_pipe): Added. Creates a pipe and sets
up a watch that triggers a config reload when one end of the pipe
becomes readable.
(signal_handler): Instead of doing the config reload in our SIGHUP
handler, just write to the reload pipe and let the associated
watch handle the reload when control returns to the main loop.
* bus/driver.c (bus_driver_handle_reload_config): Added.
Implements a ReloadConfig method for requesting a configuration
file reload via the bus driver.
* bus/main.c (signal_handler): Reload the configuration files
on SIGHUP.
(main): Set up our SIGHUP handler.
* bus/bus.c (struct BusContext): Store the config file, user and
fork flag in the BusContext.
(process_config_first_time_only): Added. Contains the code
(previously in bus_context_new) for setting up the BusContext from
the BusConfigParser that should only be run the first time the
config files are read.
(process_config_every_time): Added. Contains the code (previously
in bus_context_new) for setting up the BusContext from the
BusConfigParser that should be run every time the config files are
read.
(load_config): Added. Builds a BusConfigParser from the config
files and passes the resulting structure off to
process_config_first_time_only (assuming this is the first time)
and process_config_every_time.
(bus_context_new): All of the config-related code has been moved
to process_config_first_time_only and process_config_every_time.
Now this function just does the non-config-related initializations
and calls load_config.
(bus_context_reload_config): Added.
* dbus/dbus-watch.c (dbus_watch_handle): warn and return if a
watch is invalid when handled
* tools/Makefile.am, tools/dbus-launch.c, tools/dbus-launch.1: add
dbus-launch utility to launch the bus from a shell script. Didn't
actually implement dbus-launch yet, it's just a placeholder still.
* dbus/Makefile.am: split lists of sources into stuff that goes in
the library, util functions that go in the lib and are also used
elsewhere, and util functions that are used in tests/daemon but
don't go in the lib.
* dbus/dbus-mainloop.h, dbus/dbus-mainloop.c: move bus/loop.[hc]
here so it can be used in test binaries also
* bus/bus.c (bus_context_new): print the address in here, rather
than in main(), because we need to do it before forking the daemon

sender on the AcquireService reply

the message bus address
* dbus/dbus-sysdeps.c (_dbus_generate_random_ascii): export this

"tmpdir" option to unix: address on client side

we can use to create sockets in the test suite.

cleanly. To be used for testing.

* bus/bus.h, bus/bus.c: introduce BusContext as a global
message bus object
* test/Makefile.am (TEST_BINARIES): disable bus-test for now,
going to redo this a bit differently I think
Mega-patch that gets the message bus daemon initially handling
out-of-memory. Work still needed. Also lots of random
moving stuff to DBusError instead of ResultCode.
