Hi,
Please, i want to know why when i try to use remove_hf() and append_hf() functions with Perl (moduleFunction(func,string1,string2)), I have this message:
Jun 12 11:03:53 [12838] ERROR:core:moduleFunc: Module function 'remove_hf' is unsafe. Call is refused. Jun 12 11:03:53 [12838] ERROR:core:XS_OpenSER__Message_moduleFunction: calling module function 'remove_hf' failed. Missing loadmodule? Jun 12 11:03:53 [12838] ERROR:core:moduleFunc: Module function 'append_hf' is unsafe. Call is refused. Jun 12 11:03:53 [12838] ERROR:core:XS_OpenSER__Message_moduleFunction: calling module function 'append_hf' failed. Missing loadmodule?
Thanks, Yazid

the reason for the error you are seeing is quite technical. Functions defined in modules can define a so-called "fixup function" for parameter preprocessing. Unfortunately, doing so can result in memory leaks and all sorts of other problems, so their usage is forbidden.
append_hf as well as remove_hf are such functions.
We have had numerous discussions on that topic, but unfortunately, the results have yet been limited. A lot of work needs to be invested to create matching functions for all fixup functions in the code.
You can disable the safety checks in the perl module using a "secret" parameter, but append_hf _will_ then result in problems sooner or later.
Sorry!

Hi Bastien, Thank you for your help. I have an other question please: Can I use dynamique string ($avp(...)) as parameters in remove_hf( ) or append_hf( )? because when I execute for example remove_hf ("$avp(s:headername)") ($avp (s:headerName) = "Allow" ), I have not error but the header is not removed also.
Thanks , Yazid
