Hi,
I'm trying to remove all custom headers starting with X-, except a certain header, but
Kamailio won't start due to an error.
ERROR: <core> [route.c:1154]: fix_actions(): fixing failed (code=-1) at
cfg:/etc/kamailio/kamailio.cfg:455
remove_hf_re("^(?!X-ThisHeaderShouldNotBeRemoved)X-.*")
or
remove_hf_re("^(?!X- ThisHeaderShouldNotBeRemoved)X-")
This is valid regex according to https://regex101.com/
Any idea's why this won't compile?
Regards,
Grant

Maybe because kamailio uses a regular expression lib that doesn't
support this syntax (since there is a seperate regex module that
supports PCRE it implies the "standard" regexes don't).
Easy work around is to remove all X- headers and add them again,
something like:
remove_hf_re("^X-");
if(is_present_hf("X-ThisHeaderShouldNotBeRemoved"))
{
append_hf("X-ThisHeaderShouldNotBeRemoved:
$(hdr(X-ThisHeaderShouldNotBeRemoved))\r\n");
}
12:30 p.m.
Too bad!
Your workaround works.
I'll use that instead.
Thanks!

For the records, I just pushed a patch implementing remove_hf_exp(match,
skip) in textops module, in which allows to provide two expressions: one
to match the header for removal and one to skip the header. Will be in
the next major release.
Otherwise, besides the workaround presented in this discussion, see also
keep_hf() from textopsx, it may help in some similar situations.
Cheers,
Daniel
