rob05c opened a new pull request #4432: Fix broken ORT caching resulting in malformed config files URL: https://github.com/apache/trafficcontrol/pull/4432 Fixes ORT caching to CBOR. The current Gob encoding is fundamentally broken. See https://github.com/golang/go/issues/4609 . It's not isomorphic: it does not decode what in encodes. In practical terms, default values like 0 become null pointers, resulting in missing remap lines in the config. This changes the default to CBOR, which is an IETF RFC standard. See https://tools.ietf.org/html/rfc7049 . It also adds a unit test, to verify the default cache format is isomorphic. Gob fails the test, CBOR and JSON pass it. Includes tests. No docs, no changelog, no interface change. - [x] This PR fixes is not related to any other Issue ## Which Traffic Control components are affected by this PR? - Traffic Ops ORT ## What is the best way to verify this PR? Run unit tests. Generate remap.config with assigned delivery services of type "HTTP" (which is represented by `0`, the default int value). Without this fix, remap lines will be missing. With fix, config file should have appropriate remap lines for HTTP DSes. ## If this is a bug fix, what versions of Traffic Control are affected? - master - 4.0.x ## The following criteria are ALL met by this PR - [x] This PR includes tests OR I have explained why tests are unnecessary - [x] This PR includes documentation OR I have explained why documentation is unnecessary - [x] This PR includes an update to CHANGELOG.md OR such an update is not necessary - [x] This PR includes any and all required license headers - [x] This PR ensures that database migration sequence is correct OR this PR does not include a database migration - [x] This PR **DOES NOT FIX A SERIOUS SECURITY VULNERABILITY** (see [the Apache Software Foundation's security guidelines](https://www.apache.org/security/) for details) ## Additional Information
