For now an rvalue can be an avp, pvar, select, number, string, logical expression or script command. rvalues expressions are also supported (rvalue operator rvalue ...). Evaluation of integer rvalue expression is highly optimized. For performance reasons the rvalue expressions are completely separated from the logical expressions (eval_elem/eval_expr). - rvalue expression fixup (apart for normal fixup stuff will also optimize away simple expressions, like 2+3 or "a" + "b"). - support for more general lvalues (anything in the left side of an assignment operator). For now an lvalue is either an avp or a script pvar. lvalue = rvalue_expression. Direct assignments (lvalue to avp or pvar) are optimised. --- lvalue.c | 361 ++++++++++++++++ lvalue.h | 67 +++ rvalue.c | 1377 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ rvalue.h | 175 ++++++++ 4 files changed, 1980 insertions(+), 0 deletions(-) Diff: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commitdiff;h=1c7…

string utility functions
by Henning Westerholt 02 Dec '08

02 Dec '08

Hi, several kamailio modules need various string utility functions in the core, e.g.: - shm_strdup, pkg_strdup - str_strcmp, str_casecmp In the kamailio core we implemented this in the ut.h file. Does the SER core already provide similiar functions? If not i can move the implementation code from kamailio to this file, if this place is appropriate. Henning
