Assert cleanups and constification
 2019-10-25 13:36:00 +09:00
Zbigniew Jędrzejewski-Szmek a5648b8094 basic/fs-util: change CHASE_OPEN flag into a separate output parameter 
chase_symlinks() would return negative on error, and either a non-negative status
or a non-negative fd when CHASE_OPEN was given. This made the interface quite
complicated, because dependning on the flags used, we would get two different
"types" of return object. Coverity was always confused by this, and flagged
every use of chase_symlinks() without CHASE_OPEN as a resource leak (because it
would this that an fd is returned). This patch uses a saparate output parameter,
so there is no confusion.

(I think it is OK to have functions which return either an error or an fd. It's
only returning *either* an fd or a non-fd that is confusing.)

Zbigniew Jędrzejewski-Szmek de157fe2a7 sd-netlink: constify object pointers passed to getters 
sd-netlink is not public yet, so we can change the interface.

I did not touch interfaces of functions like sd_netlink_wait() and
sd_rtnl_message_new_link() which do not modify the object that is passed in,
because in the future we might want to change the code to e.g. take a
reference to the parent object or otherwise require a non-const reference.

Zbigniew Jędrzejewski-Szmek 730b76bd2c sd-device: allow sd_device_get_devtype to be called with NULL arg and do not assert 
We shouldn't call assert() on user-specified arguments in public functions.
While at it, let's return 1 if the type exists, and 0 otherwise.

Yu Watanabe 48fb0d1301 sd-netlink: fix invalid assertion 
It is natural that n_attiributes is less than type. But in that case,
the message does not contain any message about the type. So, we should
not abort execution with assertion, but just return -ENODATA.

Also rename cgroup_unified_update() to cgroup_unified_cached() and
cgroup_unified_flush() to cgroup_unified() to better reflect their new roles.

Lennart Poettering 6b39223cd3 sd-bus: when installing a match make sure not to apply it to already queued messages 
This tweaks match installation a bit: the match callbacks are now only
called for messages read after the AddMatch() reply was received and
never anything already read before. Thus, installing a match gives you a
time guarantee: only messages received after it will be matched.

This is useful when listening to PropertiesChanged signals as an example
to ensure that only changes after the point the match was installed are
honoured, nothing before.

Lennart Poettering 3cf8dd5359 sd-bus: destroy AddMatch() reply slot in failure case too

we received the failure for it.

This way the mere existance of the slot tells us whether the AddMatch()
method call is still pending or is complete.
