[PATCH] libmsc,sms: Properly calculate and store validity and received timestamps for incoming SMS.
This is a continuation of the patch series for the SMS validity fixes in libosmocore. Note, that this patch is based on top of the SMS DB change to remove receiver ID. It is also available in the achemeris/sms-validity-fix-master branch in the git repo. -- Regards, Alexander Chemeris. CEO, Fairwaves, Inc. / ООО УмРадио https://fairwaves.co

Please do not change the created to be the received timestamp. If you want to have a received_timestamp then introduce it. In case you hurry up we can get it into schema version 4.

I don't see any immediate needs for having created timestamps, but I agree that it's a good idea to keep it. The updated patch is attached and the branch is updated. -- Regards, Alexander Chemeris. CEO, Fairwaves, Inc. / ООО УмРадио https://fairwaves.co

In order to make this a bit more atomic I'd suggest replacing the second time() with reuse of the first value. sms->valid_until = sms->received_time + SMS_DEFAULT_VALIDITY_PERIOD; The INSERT statement change is pretty gross but oh well. //Peter

Good idea. Not sure why I didn't have this before. I've updated the branch. -- Regards, Alexander Chemeris. CEO, Fairwaves, Inc. / ООО УмРадио https://fairwaves.co

I've submitted one more patch, affecting the DB scheme. I hope we could include it into the same batch of DB changes. [PATCH 2/2] sms,db: Do not store delivered messages in the DB. -- Regards, Alexander Chemeris. CEO, Fairwaves, Inc. / ООО УмРадио https://fairwaves.co

Sure. We should do all the schema changes now.
I've updated the patch due to gsm340_validity_time() function rename. On Tue, Mar 11, 2014 at 5:33 PM, Holger Hans Peter Freyther <holger@freyther.de> wrote:
