This patch removes includes that are not used. The removals were found with include-what-you-use which checks if any of the symbols from a header is in use.
2014-11-28treewide: no need to negate errno for log_*_errno()Michal Schmidt
It corrrectly handles both positive and negative errno values.
2014-11-28treewide: auto-convert the simple cases to log_*_errno()Michal Schmidt
As a followup to 086891e5c1 "log: add an "error" parameter to all low-level logging calls and intrdouce log_error_errno() as log calls that take error numbers", use sed to convert the simple cases to use the new macros: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\("(.*)%s"(.*), strerror\(-([a-zA-Z_]+)\)\);/log_\1_errno(-\4, "\2%m"\3);/' Multi-line log_*() invocations are not covered. And we also should add log_unit_*_errno().
2014-10-22sd-bus: rename sd_bus_get_owner_uid(), sd_bus_get_owner_machine_id() and ↵Daniel Mack
sd_bus_get_peer_creds() Clean up the function namespace by renaming the following: sd_bus_get_owner_uid() → sd_bus_get_name_creds_uid() sd_bus_get_owner_machine_id() → sd_bus_get_name_machine_id() sd_bus_get_peer_creds() → sd_bus_get_owner_creds()
2014-09-15sd-bus: use proper ITERATOR_FIRST abstractionMichal Schmidt
Do not assume hashmap iterators are pointers. They may be structs in an alternative hashmap implementation.
2014-09-15hashmap: introduce hash_ops to make struct Hashmap smallerMichal Schmidt
It is redundant to store 'hash' and 'compare' function pointers in struct Hashmap separately. The functions always comprise a pair. Store a single pointer to struct hash_ops instead. systemd keeps hundreds of hashmaps, so this saves a little bit of memory.
2014-05-15sd-bus: introduce sd_bus_slot objects encapsulating callbacks or vtables ↵Lennart Poettering
attached to a bus connection This makes callback behaviour more like sd-event or sd-resolve, and creates proper object for unregistering callbacks. Taking the refernce to the slot is optional. If not taken life time of the slot will be bound to the underlying bus object (or in the case of an async call until the reply has been recieved).

2014-03-16Use strlen even for constant stringsJosh Triplett
GCC optimizes strlen("string constant") to a constant, even with -O0. Thus, replace patterns like sizeof("string constant")-1 with strlen("string constant") where possible, for clarity. In particular, for expressions intended to add up the lengths of components going into a string, this often makes it clearer that the expression counts the trailing '\0' exactly once, by putting the +1 for the '\0' at the end of the expression, rather than hidden in a sizeof in the middle of the expression.

2014-03-03bus: add sd_bus_track object for tracking peers, and port core over to itLennart Poettering
This is primarily useful for services that need to track clients which reference certain objects they maintain, or which explicitly want to subscribe to certain events. Something like this is done in a large number of services, and not trivial to do. Hence, let's unify this at one place. This also ports over PID 1 to use this to ensure that subscriptions to job and manager events are correctly tracked. As a side-effect this makes sure we properly serialize and restore the track list across daemon reexec/reload, which didn't work correctly before. This also simplifies how we distribute messages to broadcast to the direct busses: we only track subscriptions for the API bus and implicitly assume that all direct busses are subscribed. This should be a pretty OK simplification since clients connected via direct bus connections are shortlived anyway.
