Makefile list
* dbus/dbus-shared.h (#define DBUS_NAME_FLAG_ALLOW_REPLACEMENT):
New flag which replaces DBUS_NAME_FLAG_PROHIBIT_REPLACEMENT
(#define DBUS_NAME_FLAG_DO_NOT_QUEUE): New flag for specifying
not to queue an ower if it can't be the primary owner
* bus/bus.h: Add new internal BusOwner struct
* bus/driver.c (bus_driver_handle_hello): Send flags (0 for default)
to bus_registry_ensure and don't set the prohibit_replacement flag
since they are now set per BusOwner and not per name.
(bus_driver_handle_list_queued_owners): bus method (ListQueuedOwners)
that returns the list of connections in a name's connection queue
* bus/services.c (struct BusService): remove prohibit_replacement field
(struct BusOwner): new struct for keeping track of queued connections
and their associated flags for the queue
(struct BusRegistry): add a BusOwner memory pool
(bus_registry_new): initialize the BusOwner memory pool

bus owner
(bus_owner_new): new method that creates a BusOwner object from the
pool and sets its flags
(bus_owner_ref, bus_owner_unref): ref counting for BusOwner objects
(bus_registry_ensure): Add the flags parameter

instead of raw connections
(bus_service_add_owner): Add flags parameter
Switch to using BusOwner instead of raw connections
Add state machine for dealing with the new set of flags
(bus_service_swap_owner): Swaps the first and second owners in the
queue. Used to make sure proper signals are sent when a service looses
or gains primary ownership. We never insert an owner at the top of the
queue. Instead we insert it in the second position and then swap.
(bus_service_remove_owner): Remove the owner from the queue sending
out the NameLost and NameOwnerChanged signals if the we were the
primary owner

* Throughout, grand renaming to strip out the use of "service",
just say "name" instead (or "bus name" when ambiguous). Did not
change the internal code of the message bus itself, only the
programmer-facing API and messages.
* doc/dbus-specification.xml: further update the message bus section
* bus/config-parser.c (all_are_equiv): fix bug using freed string
in error case

* Land the new message args API and type system.
This patch is huge, but the public API change is not
really large. The set of D-BUS types has changed somewhat,
and the arg "getters" are more geared toward language bindings;
they don't make a copy, etc.
There are also some known issues. See these emails for details
on this huge patch:
http://lists.freedesktop.org/archives/dbus/2004-December/001836.html
http://lists.freedesktop.org/archives/dbus/2005-January/001922.html
* dbus/dbus-marshal-*: all the new stuff
* dbus/dbus-message.c: basically rewritten
* dbus/dbus-memory.c (check_guards): with "guards" enabled, init
freed blocks to be all non-nul bytes so using freed memory is less
likely to work right
* dbus/dbus-internals.c (_dbus_test_oom_handling): add
DBUS_FAIL_MALLOC=N environment variable, so you can do
DBUS_FAIL_MALLOC=0 to skip the out-of-memory checking, or
DBUS_FAIL_MALLOC=10 to make it really, really, really slow and
thorough.
* qt/message.cpp: port to the new message args API
(operator<<): use str.utf8() rather than str.unicode()
(pretty sure this is right from the Qt docs?)
* glib/dbus-gvalue.c: port to the new message args API
* bus/dispatch.c, bus/driver.c: port to the new message args API
* dbus/dbus-string.c (_dbus_string_init_const_len): initialize the
"locked" flag to TRUE and align_offset to 0; I guess we never
looked at these anyhow, but seems cleaner.
* dbus/dbus-string.h (_DBUS_STRING_ALLOCATION_PADDING):
move allocation padding macro to this header; use it to implement
(_DBUS_STRING_STATIC): ability to declare a static string.
* dbus/dbus-message.c (_dbus_message_has_type_interface_member):
change to return TRUE if the interface is not set.
* dbus/dbus-string.[hc]: move the D-BUS specific validation stuff
to dbus-marshal-validate.[hc]
* dbus/dbus-marshal-basic.c (_dbus_type_to_string): move here from
dbus-internals.c
* dbus/Makefile.am: cut over from dbus-marshal.[hc]
to dbus-marshal-*.[hc]
* dbus/dbus-object-tree.c (_dbus_decompose_path): move this
function here from dbus-marshal.c
|
| |
|
|
|
|

match rules (bug #1439).
* dbus/dbus-bus.c (dbus_bus_add_match): add a missing OOM test.
|
| |
|
|
|
| |
* COPYING: switch to Academic Free License version 2.1 instead of
2.0, to resolve complaints about patent termination clause.
|
| |
|
|
|
| |
* Update AFL version to 2.0 throughout the source files to reflect
the update that was done a while ago.
|
| |
|
|
|
|
| |
* bus/*.[ch]:
* dbus/*.[ch]:
* glib/*.[ch]: Made ref functions return the pointer

* bus/connection.c (bus_pending_reply_expired): either cancel or
execute, not both
(bus_connections_check_reply): use unlink, not remove_link, as we
don't want to free the link; fixes double free mess
* dbus/dbus-pending-call.c (dbus_pending_call_block): fix in case
where no reply was received
* dbus/dbus-connection.c (_dbus_pending_call_complete_and_unlock):
fix a refcount leak
* bus/signals.c (match_rule_matches): add special cases for the
bus driver, so you can match on sender/destination for it.
* dbus/dbus-sysdeps.c (_dbus_abort): print backtrace if
DBUS_PRINT_BACKTRACE is set
* dbus/dbus-internals.c: add pid to assertion failure messages
* dbus/dbus-connection.c: add message type code to the debug spew
* glib/dbus-gproxy.c (gproxy_get_match_rule): match rules want
sender=foo not service=foo
* dbus/dbus-bus.c (dbus_bus_get): if the activation bus is the
session bus but DBUS_SESSION_BUS_ADDRESS isn't set, use
DBUS_ACTIVATION_ADDRESS instead
* bus/activation.c: set DBUS_SESSION_BUS_ADDRESS,
DBUS_SYSTEM_BUS_ADDRESS if appropriate
* bus/bus.c (bus_context_new): handle OOM copying bus type into
context struct

(dbus_message_iter_get_object_path_array): new function (half
finished, disabled for the moment)
* glib/dbus-gproxy.c (dbus_gproxy_end_call): properly handle
DBUS_MESSAGE_TYPE_ERROR
* tools/dbus-launch.c (babysit): support DBUS_DEBUG_OUTPUT to
avoid redirecting stderr to /dev/null
(babysit): close stdin if not doing the "exit_with_session" thing
* dbus/dbus-sysdeps.c (_dbus_become_daemon): delete some leftover
debug code; change DBUS_DEBUG_OUTPUT to only enable stderr, not
stdout/stdin, so things don't get confused
* bus/system.conf.in: fix to allow replies, I modified .conf
instead of .conf.in again.
|
| |
|
|
|
|
|
|

* configure.in: define DBUS_HAVE_GCC33_GCOV if we have
gcc 3.3. Not that we do anything about it yet.
* bus/signals.c (bus_match_rule_parse): impose max length on the
match rule text
* dbus/dbus-protocol.h: add DBUS_MAXIMUM_MATCH_RULE_LENGTH

Make matching rules theoretically work (add parser).
* bus/bus.c (bus_context_check_security_policy): fix up to handle
the case where destination is explicitly specified as bus driver
and someone else is eavesdropping.
* bus/policy.c (bus_client_policy_check_can_receive): fix up
definition of eavesdropping and assertion
* tools/dbus-send.c (main): use dbus_message_type_from_string

Get matching rules mostly working in the bus; only actually
parsing the rule text remains. However, the client side of
"signal connections" hasn't been started, this patch is only the
bus side.
* dbus/dispatch.c: fix for the matching rules changes
* bus/driver.c (bus_driver_handle_remove_match)
(bus_driver_handle_add_match): send an ack reply from these
method calls
* glib/dbus-gproxy.c (dbus_gproxy_begin_call): fix order of
arguments, reported by Seth Nickell
* bus/config-parser.c (append_rule_from_element): support
eavesdrop=true|false attribute on policies so match rules
can be prevented from snooping on the system bus.
* bus/dbus-daemon-1.1.in: consistently use terminology "sender"
and "destination" in attribute names; fix some docs bugs;
add eavesdrop=true|false attribute
* bus/driver.c (bus_driver_handle_add_match)
(bus_driver_handle_remove_match): handle AddMatch, RemoveMatch
messages
* dbus/dbus-protocol.h (DBUS_SERVICE_ORG_FREEDESKTOP_BROADCAST): get
rid of broadcast service concept, signals are just always broadcast
* bus/signals.c, bus/dispatch.c, bus/connection.c, bus/bus.c:
mostly implement matching rules stuff (currently only exposed as signal
connections)
