Hi,Attached is a proposal for addressing the above issue. Stipe and I have had this discussion for a while, and I finally got round to doing it. The main driver for this has been the need for Mbuni MMS Gateway (www.mbuni.org), which uses Kannel's libs, to be able to receive MMS notifications (for those users who have a GPRS/GSM modem, rather than a full-blown MMSC connection). MMS notifications typically span more than one SMS.
The short of it is that with this patch applied:- each incoming SMS is examined to determine if it is part of a concatenated set (we look for the concatenate udh)
- if it is, we hold onto it and wait for other parts- when all parts are received, we combine them and pass on the message for further processing - if after a reasonable interval (30 mins), we haven't seen the other parts of a message, we throw the received parts away.
All changes are localised to gw/bb_boxc.c so it should be reasonably easy to check that nothing is broken.
I have tested this with a live implementation, using both concatenated plain text and a picture message (which has a longer UDH), and it works nicely. Kindly review.
Thanks PaulPs. Also included is a previous patch, proposing some improvements to my earlier improvements to the mime module. Generally these had to do with reducing the amount of copying of objects.
