write_file(), as written wasn't transaction-safe; a crash bewtween a
file being open and the buffer being written before a safe close would
leave the file with a set of undetermined contents.
Modified to the file is written to a temporary file name; once
completed, it is renamed to the final name. This way, a crash in the
middle doesn't leave half-baked files.

This adds a simple API to use for generating unique IDs for SMS
messages. Will be used by follow up commits.
The ID is not generic, but specifc to SMS messages (due to having to
dig inside 'struct sms') and thus generates directly 16-bit IDs.

This part is wrong, the user-data (ud) is not the entirety of the PDU.
It is just the message payload. Hashing over it only is not enough.

The current message id is 32 bits. Why are we stopping@16? We could
go all the way to 64 if needed...
Also, we need to take time and some random value into account. Perhaps
including time() output and a simple static counter into the hashing
function would make it unique for those 'same sender, same contents
messages'

So which other fields for each type in the union are to be taken into
account?
From our discussions, I was under the impression that we wanted to hash
only on the contents of the message and destination -- this actually led
to the problem of the same sender and data issue below...[more on it
below].

Well, at the end what gets sent to the network is 16 bits right?

So then we really don't care about being able to regenerate the hash ID
from the contents?
The design discussions we held about this involved being able to, with
the content of the message and destination number, generating a hash
that could be uniquely reproduced by rehashing it again. You had a
reason for it and I can't remember which one it was -- I should have
written it down. But that brought the problem of 'somebody sending the
same message to the same number' which yields the same ID.
However, if to fix that we are adding randomness in the form of time(),
why bother with the contents? let's just do a random ID from the ground
up and save us the pain of hashing.

So I think we're all confused here. This ID is not being sent to the
network. It is only used for uniquely identifying the message over
D-Bus and to message history. This number can be as small or as big as
we want.

I don't remember this discussion any more. There might be a case where
an old message is re-delivered because oFono crashed after delivery but
before deletion.
At least to me it seems that generating a random int is really not
guaranteed to be unique over reboots. Hashing seems way better.
However, I'm not a math/crypto geek, so feel free to prove me wrong.

I was under the impression that you wanted to use this for the ref also,
and thus it is imprinted into the PDUs by set_ref_and_to(). Can you
confirm this?

Ok, I see your concern. Proper seeding of the RNG should take care of
that case, but either way works. If you want hashing + time() seeding
that can be done easily.
I still could use clarification on which other fields of the 'struct
sms' union you want to have hashed other than the PDU payloads.

No, you're totally confused ;) Ref is only sent on messages that are
multi-fragment. It is not used for single-fragment messages. The logic
is currently implemented per spec and I never had the intention to do it
any other way.

All of them. Again, it might be much simpler to do this over the
fragments when they are in true PDU form. This can be done in
sms_assembly and tx_queue_entry_new since they deal with fragments already.
Alternatively handling the individual structure fields can be done as well.

Okay, so then this means that all the current ref infrastructure
(monotonically increased) is left in place and the message ID stuff is
used only internally for D-Bus and whichever other needs there are. I'll
up it to 64-bits.

I'll look into it.

On the RX path, it is not going to be easy to use the raw PDUs to
generate a UUID:
whoever code gets the PDU
ofono_sms_deliver_notify(PDU)
PDU decoded into a 'struct sms'
handle_deliver(struct sms)
added to fragment list in assembly
sms_dispatch(fragment list of 'struct sms')
so if we also want to generate a UUID of this based on RAW PDUs, either
we keep the raw PDU around or we base the UUID generation from the
struct sms fields. We could really only generate this at sms_dispatch()
or similar, where we have the fragments in the proper order.
Thoughts?

This patch removes the sequential SMS message identification gig and
replaces it with a 16-bit hash cookie based off message contents.
FIXME: [incomplete] need to figure out how to do so that identical
messages sent to different or the same numbers also have a different
ID.

You're calculating the ID before setting the ref and to? That is pretty
silly ;)

Make the ID calculation happen inside tx_queue_entry_new. That function
already converts all the SMS objects into a PDU. So simply hashing the
PDUs there would be very easy.

Once we settle on the ref / msg_id part, that one will sort out by
itself.
On later commits, the callback has to change in order to be able to
implement PropertChanged signals. Unless you have a better way to do it
that doesn't involve poking with 'struct tx_queue_entry' internals. A
helper to set the callback after the fact is another option, but it is
way dirtier.
Likewise with the return value (msg id vs the struct itself). You
suggested poking at the head of the queue upon return. That is peeking
on internals and you have adamantly (and rightfully) argued against it
in other cases.

the ref was supposed to be generated off the msg ID according to your
initial design decisions, so this is following spec. We need to clarify
this (and this touches with the other email).

Ok, holding until we confirm what relationship there will be between ref
and msg_id.

Introduce a destructor function to encapsulate all the release steps
for this data type, as more are to be added later.

This adds state to outgoing/in-transit SMS messages. This will be used
later on for persistence / D-Bus, when the SMS life cycle is expanded.
The state is a variable in the 'struct tx_queue_entry' which gets
updated as messages go through the hoops.

A WSR (Waiting for Status Report) state definition is added to the
state transtition machine; as well, a queue (ofono_sms->tx_wfaq) where
messages waiting for an status report are queued. When the message's
delivery is acknowledged, the message is removed from the queue and
the message's status machine is updated, which can trigger things such
as D-Bus signals.

When the SMS message going through the TX hoops changes states, call
the given callback function (if any). This will be used later to hook
up the D-Bus propagation of property changed signals.
Note this will do away with the ofono_sms_txq_submit_cb callback, as
it can be implemented in terms of a state change callback.

Splits sms_send_message() into a D-Bus front end and an internal API:
- sms_msg_send(), a full C interface for SMS sending
- dbus_sms_msg_send(): adapts sms_msg_send() to be a D-Bus call,
exporting the object on the bus, returning its name and setting up
all the callbacks and D-Bus specific data. The call is synchronous.
This allows internal code to use the same infrastructure as D-Bus
clients to send SMS messages.

This hooks sms_msg_stch_dbus_cb() into the SMS state change callback
so that a D-Bus signal will be emitted whenever an SMS Message
transitions state. This allows a client to track, if desired, what is
going on with the SMS Message it cares about.

This introduces the ability to cancel a pending SMS message,
accessible via an internal API and over a D-Bus wrapper.
Sending a note to the network to cancel an in-transit message is not
yet implemented.
Note the test case code requires follow up commits that propagate the
message's state changes over D-Bus.

Currently this only returns the state of the SMS message and the
destination number. Note we make the @receiver field in 'struct
tx_queue_entry' be always filled out in __ofono_sms_txq_submit() as
now it is always needed for the properties, not only when a Status
Report is requested.

When running 'make distcheck' from a vpath build directory (ie: one
that is not where the source lives), the target headers in
include/ofono are not generated properly due to a typo in the
Makefile.am, that is using _srcdir where _buildir should be being
used.
