[Kamailio-Users] lcr module prefix_mode=1

[Juha Heinanen]

by accident i sent this message to devel list when i intended to send it
to users list.

i'm thinking to speed up lcr load_gws() implementation by storing prefixes
into hash table.  it would allow load_gws() to execute (if necessary) in
constant time independent of the number of prefixes.  also, i'm planing
to make the size of hash table controllable by module parameter.

the side effect of this is that prefix_mode=1, where prefixes are
regular expressions, would have to be dropped, because hashing on
regular expressions makes no sense.

something close to prefix_mode=1 could be achieved using dialplan module
to store the regular expressions and return as attribute a gateway
grp_id.  that could then be used by new load_gws_from_group(grp_id) to
load gws in the given group.

any comments on this?  is someone depending on prefix_mode=1?

by the way, before starting this project, i took a look at opensips
drouting module, but unfortunately it does not cover many features of
lcr module that i use in my configurations and thus cannot be used to
replace lcr module.
