Rene Krenn	82af5cf518	MT#62283 "for update no lock" logic for GET /subscribers and /contracts ... to unblock the web UI on heavy loaded systems with call rating enabled, "select .. for update no lock" will no longer wait for acquiring locks when retrieving subscriber or contract contract pages. the contract_balance record creation is will be skipped for such contracts that are locked elsewhere. for rails such as /customerbalances, an explicit contract id row lock timeout is introduced, so it does not depend on the mariadb wait_timeout.

Rene Krenn	672a3110bc	MT#59216 restore appending wildcard behaviour ... with the change to harmonize wildcard symbols % and * to * in query param filters across all restapi rails, only - /api/subscribers?alias= - /api/subscribers?pbx_extension= - /api/subscribers?primary_number= - /api/pbxdevices?pbx_extension= are supposed to include implicit leading an trailing wildcards. panel UI uses trailing wildcard by default everywhere, and so should the databales of the new Admin UI. external_id were used to support patterns, but must not include a trailing wildcard in rest API, as this can break logic that rely on unique api request results. we now therefore no longer append wildcards in particular to: - /api/voicemails?folder= - /api/voicemailgreetings?type= - /api/subscribers?subscriber_external_id= - /api/subscribers?customer_external_id= - /api/subscribers?display_name= - /api/subscribers?domain= - /api/profilepackages?profile_name= - /api/profilepackages?network_name= - /api/pbxdevices?display_name= - /api/faxserversettings?name_or_password= Change-Id: I40ef1912d7224a56c6d14619d258c70e447ab23d	2 years ago
