[PATCH 0/3] Persist TX SMS messages

[PATCH 0/3] Persist TX SMS messages

[Kristen Carlson Accardi]

[-- Attachment #1: Type: text/plain, Size: 1160 bytes --]

This patch series implements a method of persisting pending
outgoing sms messages on disk.  Once an sms message has
been submitted to the transmit queue, each pdu in the
message is stored on disk until the driver indicates that
it has been sent.

Each tx_queue_entry is given an id number that represents
it's order in the queue.  A subdirectory per entry is
created as id-uuid, in order to preserve order when the
queue is loaded in the event of a crash.  Within each
subdirectory, each pdu is saved in order by sequence
number.

When an sms driver is ready for operation, the disk will
be scanned for any saved pending tx sms messages.  If there
are any found, they will be loaded from disk and placed
into the queue in order.

I think that using a static variable for this is a bad idea.  You
probably want to add this to the sim atom itself.  More on this a bit later.

Is there a reason for the type of id and the type of tx_counter to be
different?

I'd really prefer i = 0, l = list here

And where are you taking care of storing the other needed information?
e.g. the tx_queue entry flags, retry count, etc?

Otherwise I'm happy with this one.

I can easily add the flags and retry count.  As far as the "etc"
that you mention, the only other information I see would be
entry->cb and entry->data, which I was thinking might have to
get lost.  I am not sure how to persist that information on
disk - do you have any suggestions?

There's really no way to persist these, so losing them is fine for now.
 The only entity who makes use of the callback is the stk atom, and
those sms messages should not be serialized to disk.  e.g. we should not
try to persist messages that do not have at least the
OFONO_SMS_SUBMIT_FLAG_EXPOSE_DBUS set.

Can't you use g_queue_get_length() here to get the position of the
newly pushed entry? That would make tx_counter unnecessary (and
anyway, it should probably be internal to each sms atom data instead
of a static variable).

Need to explicitly compare to NULL here. A recently added convention, I admit.

I'm not sure this is going to work, e.g. start with tx_counter == 0:

Queue -> tx_counter = 1, id = 0
Queue -> tx_counter = 2, id = 1,
Queue -> tx_counter = 3, id = 2,

Sent -> tx_counter = 2, (id of 0 sent)

Queue -> tx_counter = 3, id = 2

Now you have two messages with the same id and lost all guarantees on
the order...

Perhaps simply relying on always increasing tx_counter might be enough.
 It is unlikely anyone will ever send 4 billion SMSes ;)  Renaming the
directory during the restore operation might be an option as well.

The existing code tends to name this foo_backup_free rather than
backup_destroy.

As I mentioned before, you should be restoring this information.
Assuming that it is the same for all messages on the tx queue is a
really bad idea.

Using sms_txq_submit is a bad idea.  This one will re-calculate the UUID
which gets tossed out later.  I suggest creating the tx_queue entries 'raw'.

[PATCH 0/3] Persist TX SMS messages

[Lucas De Marchi]

[-- Attachment #1: Type: text/plain, Size: 806 bytes --]

This patch series is a re-sending of a previous series sent by Kristen Carlson
Accardi. What I did was some cleanups, style changes, ported it to the new sms
API and fixed some leaks (hopefully I didn't introduce more).

Marcel/Denis, I don't know if letting "Based on patch from" is the right
approach. Feel free to change the author of the commits if you think this more
appropriate.

Lucas De Marchi (3):
  sms: store pending tx pdus on disk
  sms: delete sent sms messages from backup
  sms: restore pending tx messages from backup
