This simply verifies that we forward unix fds only on connection that
support it. We willr eturn an error if a client attempts to send a
message with unix fds to another client that cannot do it.
|
|
|
|
| |
in once piece right now
|
|
|
|
| |
This make all counters count both bytes of memory and unix fds.

When appending unix fds to the message a new entry in the fd array will
be allocated and the index to it will be written to the message payload.
When parsing unix fds from the message the index will be read from the
payload and then looked up in the fd array.
When we read fds we put them in a queue first. Since each message knows
how many fds are attached to it we will then pop enough fds from this
queue each time we decode a message from the stream.
This should make sending and receiving more portable since we don't make
any strong requirements on the exact semantics of the SCM_RIGHTS
implementation: as long as fds are recieved in order, none or lost and
the arrive at the same time as at least one byte from the actual message
dat we should be able to handle them correctly.

Some projects want to reuse the DBus message format, without
actually going through a DBusConnection. This set of changes
makes a few functions from DBusMessage public, and adds a new
function to determine the number of bytes needed to demarshal
a message.

2007-09-19 Ryan Lortie <desrt@desrt.ca>
* dbus/dbus-string.[ch] (compact, _dbus_string_compact,
_dbus_string_lock): new compact function to free up allocated memory
that is no longer used.
* dbus/dbus-message.c (load_message): call _dbus_string_compact on the
message loader buffer.
* dbus/dbus-transport-socket.c (do_reading, do_writing): call
_dbus_string_compact on the incoming/outgoing "encoded" buffers.
* dbus/dbus-string-util.c (_dbus_string_test): add a few tests for
string compacting.
|
|
|
|
|
|
|
| |
* dbus/dbus-message.c (dbus_message_get_cached)
(dbus_message_cache_or_finalize): don't mess with message from
message cache outside of the cache lock. Bug #9164 from Jonathan
Matthew.
|
|
|
|
| |
* Add indent-tabs-mode: nil to all file headers.
|
|
|
|
| |
DBUS_GNUC_DEPRECATED to DBUS_DEPRECATED and extended to msvc compiler
|
|
|
|
|
|
| |
* dbus/dbus-message.c (dbus_message_iter_open_container): Fix
broken return_if_fail (kind of scary that test suite does not
cover this)
|
|
|
|
|
| |
* dbus/dbus-message.c (dbus_message_iter_open_container): improve
the checks/warnings for contained_signature a bit
|
|
|
|
|
| |
* dbus/dbus-message.c: improve some docs related to reading values
from a message iter
|
|
|
|
|
|
| |
Add API to convert a DBusMessage to/from a byte array.
Patch from Dafydd Harries <dafydd.harries@collabora.co.uk>, approved by
Havoc Pennington.
|
|
|
|
|
|
|
| |
* dbus/dbus-macros.h: add DBUS_GNUC_DEPRECATED macro
* dbus/dbus-message.h: mark dbus_message_iter_get_array_len()
as DBUS_GNUC_DEPRECATED
|
|
|
|
|
| |
* Move all private API into the private Doxygen group sections of
the files, so they don't show up in the public API docs
|
|
|
|
|
|
|
| |
* dbus/dbus-message.h: put #ifndef DBUS_DISABLE_DEPRECATED around
dbus_message_iter_get_array_len().
* throughout: documentation improvements.
|
|
|
|
|
|
|
|
|
|
|
|
|
| |
* doc/TODO: remove the int64 thing from 1.0 since it doesn't
matter, and the message-loader-breaker thing since nobody is going
to do it. Add an item to 1.0 about supporting recursive locks
in dbus_threads_init_default() though, since it should be easy.
* dbus/dbus-connection.c (_dbus_connection_read_write_dispatch):
Fix this in the !dispatch case to avoid busy-looping after
disconnection
* More misc docs improvements
|
|
|
|
| |
* Fix a pile of Doxygen warnings and missing docs

static DBusList *uninitialized_condvar_list to support new late
initialization threading model. In this model threads can be initialized
even after the D-Bus API has been used but still needs to be initialized
before the second thread has been started. Mutexes and condvar addresses
are stored in the two static lists and are replaced with actuall locks
when threads are initalized.
(_dbus_mutex_new_at_location): New method for creating a mutex and placing
the location into the static list
(_dbus_mutex_free_at_location): New method for removing a mutex location
from the static list and freeing the mutex
(_dbus_condvar_new_at_location): New method for creating a conditional
variable and placing the location into the static list
(_dbus_condvar_free_at_location): New method for removing a conditional
variable location from the static list and freeing the conditional variable
(init_uninitialized_locks): Atomic method which goes through the static
lists of mutex and condvar location and updates them with actuall locks
(init_global_locks): changed to init_locks
* dbus/dbus-connection.c:
(_dbus_connection_test_get_locks): New method for tests to check connections
(_dbus_connection_new_for_transport): Use the new at_location mutex and
condvar API
(dbus_connection_allocate_data_slot): Pass in the global lock address
to _dbus_data_slot_allocator_alloc
* dbus/dbus-dataslot.c:
(_dbus_data_slot_allocator_alloc): Use the address of the mutex
instead of the mutex itself
* dbus/dbus-message.c:
(dbus_message_allocate_data_slot): Pass in the global lock address
to _dbus_data_slot_allocator_alloc
* dbus/dbus-pending-call.c:
(dbus_pending_call_allocate_data_slot): Pass in the global lock address
to _dbus_data_slot_allocator_alloc
* dbus/dbus-server.c:
(_dbus_server_init_base): Use the new at_location mutex API
(dbus_server_allocate_data_slot): Pass in the global lock address
to _dbus_data_slot_allocator_alloc

* dbus/dbus-message.c (dbus_message_iter_get_fixed_array):
Patch from Rob Taylor <rob.taylor@collabora.co.uk> to correct a bogus
assertion that the next element to read from the iter is fixed in
size. This is not the case when you are at the end of the iter,
because the next element type is INVALID.
* dbus/dbus-string.c (_dbus_string_init_const_len): Correct a
a bogus assert which means that you may not initialise a 0-length
string unless you provide a non-NULL pointer. This prevented
you from marshalling messages containing zero-length arrays in
some cases.
* glib/dbus-gvalue.c (demarshal_collection_array): Another patch
from Rob to correct bogus asserts when trying to demarshal an
array and get_fixed_array got you 0 elements. Append nothing to
the GArray in this case.
* test/glib/test-dbus-glib.c: Add a test case for round-tripping
an empty array via the glib bindings. Without all of the above
patches, this new test fails.
|
|
|
|
|
| |
* dbus/dbus-message.c (dbus_message_set_reply_serial): print
warning if the reply serial is set to 0

(dbus_message_has_path): New method
(dbus_message_has_interface): New method
(dbus_message_has_member): New method
* dbus/dbus/dbus-sysdeps.c (_dbus_check_dir_is_private_to_user):
New method
* dbus/dbus-keyring.c (_dbus_keyring_reload): Check to see that
the keyring directory is private to the user
* doc/TODO:
- The convenience functions in dbus-bus.h should perhaps have
the signatures that they would have if they were autogenerated
stubs. e.g. the acquire service function. We should also evaluate
which of these functions to include, in light of the fact that
GLib/Qt native stubs will probably also exist.: Punted
- add dbus_message_has_path(), maybe has_member/interface:
fixed in this patch
- in dbus-keyring.c, enforce that the keyring dir is not
world readable/writable: Fixed in this patch

stack values are then used to validate that dict entries have only two
elements within them.
(validate_body_helper): check the reason for failure when validating
varients
* dbus/dbus-message.c (load_message): use
DBUS_VALIDITY_UNKNOWN_OOM_ERROR in places where we previously used

GType.
(dbus_gvalue_init): Just invoke dbus_dbus_type_to_gtype and
initialize the value with it.
(dbus_gvalue_binding_type_from_type): Unused, delete.
(dbus_gvalue_demarshal): Switch to hardcoding demarshalling for
various types instead of unmarshalling to value data directly.
Remove can_convert boolean.

This is about it on what can be disabled/deleted from libdbus
easily, back below 150K anyhow. Deeper cuts are more work than
just turning the code off as I've done here.
* dbus/dbus-marshal-basic.c (_dbus_pack_int32): we don't need the
signed int convenience funcs
* dbus/dbus-internals.c (_dbus_verbose_real): omit when not in
verbose mode
* dbus/dbus-string-util.c, dbus/dbus-string.c: more breaking
things out of libdbus
* dbus/dbus-sysdeps.c, dbus/dbus-sysdeps-util.c: same
* dbus/dbus-hash.c: purge the TWO_STRINGS crap (well, make it
tests-enabled-only, though it should probably be deleted)
* dbus/dbus-message-util.c: same stuff

* 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
