Well it introduces a performance delay, probably to all SMS, but it is configurable, and if you need it you've got to have it. Any chance to improve on it by putting the deliver_sm back into the queue instead of sleeping?

This aims to solve the problem we were having with dlr's arriving before the row is inserted. 2 new core parameters are defined: dlr-retry-count -> How many times do we attempt to fetch the dlr? Default: 1 dlr-retry-delay -> How many milliseconds do we sleep before retrying? Default: 0 So, if you don't set these parameters the behaviour remains as it was before patching. However, if you, for example, set: dlr-retry-count = 3 dlr-retry-delay = 200 Kannel will try 3 times in total (the original one plus 2 more), pausing 200ms (0.2 seconds) before each attempt. If after the third attempt the DLR's still missing, Kannel will display a warning as usual. ------------------------------------------------------------------------------ Regards, -- Alejandro Guerrieri [email protected] ------------------------------------------------------------------------------ Resubmitting this patch by popular demand ;) http://www.blogalex.com/archives/132 Regards, -- Alejandro Guerrieri [email protected] Begin forwarded message: > From: Alejandro Guerrieri <[email protected]> > Date: 2 de mayo de 2009 14:48:19 GMT+02:00 > To: Kannel Devel <[email protected]> > Subject: [PATCH] dlr retries > > Hi, > > This patch implements an "sleep and retry" when calling dlr_get(). > This aims to solve the problem we were having with dlr's arriving > before the row is inserted. > > 2 new core parameters are defined: > > dlr-retry-count -> How many times do we attempt to fetch the dlr? > Default: 1 > dlr-retry-delay -> How many milliseconds do we sleep before > retrying?
