Turning off IPv6 causes the tests to fail because the Go
`net.Listen()` function obtains a `[::]` address when using
a `localhost:0` bind address. Looking through the Go source
code, I don't see a good way to fix that.
This change adds a test flag to allow users to specify the
network name when running the test:
```sh
go test github.com/pilosa/pilosa/server -network tcp4
```
Renames `config` to `generate-config` and implements a new `config`
command that generates the configuration file based on the current
state instead of printing a static string.
A configurable limit has been added to restrict the number of
mutating calls in a `pql.Query`. This is to prevents requests from
timing out from large queries.
The default is set to 5000 writes per request and is configurable
through the configuration file and the command line flags.
It is nested under "cluster" in the config, and it controls cluster membership
as well as broadcasting, so I think type is more appropriate. Also, brevity.
Primary message interface is the MessageBroker which is an attribute of the Messenger.
MessageBroker implementations:
- Gossip (memberlist)
- Broadcast (uses HTTP, received by existing Handler)
- Static (no-ops)
Changes CacheSize from `int` to `uint32` for consistency with protobuf.
Removes unnecessary dependencies in glide:
- `github.com/aws/aws-sdk-go`
- `golang.org/x/net` (although this gets included by memberlist)
TODO:
- [ ] Add tests around the Messenger and MessageBroker objects.
- [ ] Refactor CreateSliceMessage to work with views.
- [ ] Support propogation of meta data on PATCH calls.
fixing some issues from last rebase
Previously, multiple frames with different prefixes were used to separate
different data layouts. This included separating standard row/column
layouts from inverted column/row layouts as well as storing aggregate
information for timestamp data.
Unfortunately, this caused frame meta data to be copied between multiple
frames and it made it difficult to keep these frames in sync.
This commit separates these different physical layouts into `Views`.
A `Frame` now has one or more views which represent each layout.
Fragments have been moved from under the `Frame` to be contained
within the `View`.
There are two primary views:
- `standard`
- `inverse`
If a frame has a time quantum, then views are generated for these
each of the standard/inverse views. For example a time quantum
of `YMDH` for the date `2000-01-02T00:00:00Z` would create the
following views:
- `standard_2000`
- `inverse_2000`
- `standard_200001`
- `inverse_200001`
- `standard_20000102`
- `inverse_20000102`
From the user's perspective, nothing should change in PQL. Different
PQL statements will handle the appropriate view automatically. For
example, `Bitmap()` and `Profile()` will fetch using the `standard`
view or the `inverse` view, respectively. The `Range()` statement
will lookup the appropriate time-based views automatically.
