Some datastore and service methods would return slices of structs,
rather than slices to pointers of structs (which most methods used).
Make this more consistent.
- Include only hosts that the user has access to in search targets API.
- Add parameter to specify whether `observer` hosts should be included.
- Generate counts based on which hosts user can access.
- Update API doc.
This change optimizes live queries by pushing the computation of query
targets to the creation time of the query, and efficiently caching the
targets in Redis. This results in a huge performance improvement at both
steady-state, and when running live queries.
- Live queries are stored using a bitfield in Redis, and takes
advantage of bitfield operations to be extremely efficient.
- Only run Redis live query test when REDIS_TEST is set in environment
- Ensure that live queries are only sent to hosts when there is a client
listening for results. Addresses an existing issue in Fleet along with
appropriate cleanup for the refactored live query backend.
Push the calculation of target counts into the SQL query, rather than loading
all of the targets and then counting them. This provides a dramatic (>100x)
speedup in loading of the manage packs page when large numbers of hosts are
present.
Closes#1426
Notable refactoring:
- Use stdlib "context" in place of "golang.org/x/net/context"
- Go-kit no longer wraps errors, so we remove the unwrap in transport_error.go
- Use MakeHandler when setting up endpoint tests (fixes test bug caught during
this refactoring)
Closes#1411.
