Previously the only roundtrip test was for an empty report.
This test has fake data similar to that found in real reports.
'Metrics' does not round-trip exactly, so a DeepEqual workaround is
added for that.
It is unused and none of the adjacency mapping code in the renderer
takes any notice of it. Removing this shrinks the report size.
Edges were introduced in #838. At the time we had an experimental
packet sniffer under experimental/sniff/sniffer.go. That got removed
in #1646.
We can resurrect this if we ever decide to add meta data to edges.
This allows plugins to add controls to nodes that already have some
controls set by other plugin. Previously only the last plugin that
sets the controls in the node would have its controls visible. That
was because of NodeControls' Merge function that actually weren't
merging data from two inputs, but rather returning data that was newer
and discarding the older one.
This commit makes the LatestMap type a sort of a base class, that
should not be used directly. This also adds a generator for LatestMap
"concrete" types with a specific data type in the LatestEntry.
Merge() is always returning a copy, so there is no need to Copy()
struct fields first before calling Merge() on them.
This reduces GC pressure (#1010) and helps overall app performance
(#1457).
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
