Squash of:
- including children in topologies_test.go
- report.Node.Prune should prune children also
- rewrote ShortLivedInternetConnections test to express its intent
- adding tests for detail Summary rendering
Squash of:
- use detailed.Summaries to render topology nodes
- ban merging nodes of different topologies (they should be mapped)
- need to prune parents when mapping node types
- render container images by id if they have no name
- remove separate render ids and prune parents in NewDerived*
- don't render metrics/metadata for groups of nodes
- fixing up tests
- removing pending unit tests (for mapping.go, for now)
- updating experimental dir for RenderableNode removal
* Bump github.com/ugorji/go/codec, to get fixes which make
github.com/2opremio/go-1/codec unnecessary
* Remove github.com/2opremio/go-1/codec
* Remove type embeddings to avoid the problem explained at
https://github.com/ugorji/go/issues/141#issuecomment-185450157
* New encoding format:
* Msgpack reports between probe<->app (smaller representation, faster to
encode/decode).
* Still use JSON between app<->UI (try to avoid making javascript deal with
mspack).
The app still suports publishing reports in both gob and JSON, not braking
backwards compatibility.
* Use compile-time generated marshallers/unmarshallers for higher performance. In
order to be able to skip code-generation for certain types, I included
https://github.com/2opremio/go-1/tree/master/codec/codecgen instead of
upstream until https://github.com/ugorji/go/pull/139 is merged.
* Encode/decode intermediate types using github.com/ugorji/go/codec.Selfer
for higher performance and reducing garbage collection (no temporary buffers).
- base load graph x-axis on data, not a hardcoded window
- format memory dynamically to scale
- add some tests for the immutability of metrics
- use ps.List for Sample storage, so it is immutable. Have to implement custom marshalling
- adding tests for report.Metrics
- check the ordering of the json samples
- Make the nil value for Metrics valid.
- Sort samples from oldest to newest on the wire.
