Bug 20292: Filter/censor info sent via SIP

Some libraries would like to limit the amount of personal information a SIP server sends
to arbitrary parties on a per-login basis.

Test Plan:
1) Add a new key/value pair to one of your existing login stanzas in your SIP config file
   For example: hide_fields="BD,BE,BF,PB"
2) Restart SIP
3) Send a SIP message that would normally return those fields ( in this example, a Patron Information Request )
4) Note the response has had those fields removed

Comment 9 Marcel de Rooy 2019-05-31 09:26:27 UTC
+            $resp .= add_field( FID_FEE_AMT, $status->fee_amount, $server );
+            $resp .= maybe_add( FID_CURRENCY,       $status->sip_currency, $server );
+            $resp .= maybe_add( FID_FEE_TYPE,       $status->sip_fee_type, $server );
+            $resp .= maybe_add( FID_TRANSACTION_ID, $status->transaction_id, $server );

I have some doubts here. Will this work if people add such fields to the hidden list? Or should these be added no matter what? So moved to add_field?
Maybe there are more ?

I see no reason to override a librarian's ability to scrub any particular SIP field. That just makes the feature inconsistent, and for all we know maybe there *will* be a scenario where a library needs to not send those fields to a particular service.

In the assumption that we are not stripping fields that the SIP standard dictates, I guess you are right. And if we do, we should not ;)

Passed QA
Comment 13 Marcel de Rooy 2019-06-07 07:56:16 UTC
Note to RM: We should be a bit careful with future SIP patches that still have the old maybe_add behavior in mind? In some cases they should use add_field now?

Hear hear! Yes, please back-port this to 19.05.x. We need it at our site a.s.a.p. Please let me know how I can help make this happen.

This is marked as an enhancement, not as a bug - enhancements are usually not backported. It's up to the Rmaints to make exceptions, but it might help to reason why this should be in an oldstable version.
Comment 18 Lucas Gass 2020-02-12 23:21:16 UTC
this applied clean, passes all test, so I will go ahead and backport to 19.05.x for 19.05.08
Comment 19 Hayley Pelham 2020-02-13 23:13:03 UTC
Enhancement will not be backported to 18.11.x.
