This can be used to implement wrapper backends,
while passing a private pointer to the backens init function
via ev->additional_data.

Set/get a single callback function to be invoked at various trace
points. Define "before wait" and "after wait" trace points - more
trace points can be added later if required.
CTDB wants this to log long waits and events.

This adds more flexible handling for the add operation:
- It allows the caller to remove a tevent_req from the queue
by calling talloc_free() on the returned tevent_queue_entry.
- It allows the caller to optimize for the empty queue case,
where it the caller wants to avoid the delay caused by
the immediate event.

This way the caller can add a blocker to the queue.

This is a replacement for tevent_req_nomem(NULL, req)
|
|
The usecs arguments are (of course) microseconds, not milliseconds.
This was added by Andreas Schneider in 6c1bcdc2 (tevent: Document the
tevent helper functions.).

There is no such flag.

This allows us to re-initialise a tevent context without destroying
the pointer. That means that if someone keeps a long term ptr to the
event context across a fork it will still work.
This also brings the memory handling in single and standard process
models much closer together, which means less bugs that we don't find
with make test.

This offers a generic way for callers to cancel an
async request.

move publicly needed structures and functions in the public header.
Stop installing internal headers.
Update the signature and exports files with the new exposed
function.

This is necessary for requests that have multiple results. Examples would be
SMBEcho and ldap_search.

This is very useful to find bugs.
You can use 'p *req' in gdb to show where
tevent_req_done(), tevent_req_error() or tevent_req_nomem()
was called.

They're like directly triggered timed events,
but you can preallocated them and scheduling them
will not fail.

This is only a hack for samba4 and should not be used
in new code.

This is an ugly hack to let the s4 server work arround
some bugs related to nested events and uid changing.

Incompatible caller should use tevent_loop_allow_nesting()
function.

Not every tevent backend supports signal events.

Callers can use it instead of tevent_req_callback_data()
if they use a non talloc private pointer.
metze
|
|
This function can be called as last action of a _recv()
function, it destroys the data attached to the tevent_req.

Move struct tevent_req in tevent_internal, and ad getters and setters
for private data and the callback function.
This patch also renames 'private_state' into 'data'. What is held in this
pointer is in fact data and not a state like enum tevent_req_state.
Calling it 'state' is confusing.
The functions addedd are:
tevent_req_set_callback() - sets req->async.fn and req->async.private_data
tevent_req_set_print_fn() - sets req->private_print
tevent_req_callback_data() - gets req->async.private_data
tevent_req_data() - gets rea->data
This way it is much simpler to keep API/ABI compatibility in the future.

This can be used as tevent_req based timer event.

This makes more clear what the function does.
