captplanet (#159)
* captplanet
I kind of went overboard this weekend.
The major goal of this changeset is to provide an environment
for local development where all of the various services can
be easily run together. Developing on Storj v3 should be as
easy as running a setup command and a run command!
To do this, this changeset introduces a new tool called
captplanet, which combines the powers of the Overlay Cache,
the PointerDB, the PieceStore, Kademlia, the Minio Gateway,
etc.
Running 40 farmers and a heavy client inside the same process
forced a rethinking of the "services" that we had. To
avoid confusion by reusing prior terms, this changeset
introduces two new types: Providers and Responsibilities.
I wanted to avoid as many merge conflicts as possible, so
I left the existing Services and code for now, but if people
like this route we can clean up the duplication.
A Responsibility is a collection of gRPC methods and
corresponding state. The following systems are examples of
Responsibilities:
* Kademlia
* OverlayCache
* PointerDB
* StatDB
* PieceStore
* etc.
A Provider is a collection of Responsibilities that
share an Identity, such as:
* The heavy client
* The farmer
* The gateway
An Identity is a public/private key pair, a node id, etc.
Farmers all need different Identities, so captplanet
needs to support running multiple concurrent Providers
with different Identities.
Each Responsibility and Provider should allow for configuration
of multiple copies on its own so creating Responsibilities and
Providers use a new workflow.
To make a Responsibility, one should create a "config"
struct, such as:
```
type Config struct {
RepairThreshold int `help:"If redundancy falls below this number of
pieces, repair is triggered" default:"30"`
SuccessThreshold int `help:"If redundancy is above this number then
no additional uploads are needed" default:"40"`
}
```
To use "config" structs, this changeset introduces another
new library called 'cfgstruct', which allows for the configuration
of arbitrary structs through flagsets, and thus through cobra and
viper.
cfgstruct relies on Go's "struct tags" feature to document
help information and default values. Config structs can be
configured via cfgstruct.Bind for binding the struct to a flagset.
Because this configuration system makes setup and configuration
easier *in general*, additional commands are provided that allow
for easy standup of separate Providers. Please make sure to
check out:
* cmd/captplanet/farmer/main.go (a new farmer binary)
* cmd/captplanet/hc/main.go (a new heavy client binary)
* cmd/captplanet/gw/main.go (a new minio gateway binary)
Usage:
```
$ go install -v storj.io/storj/cmd/captplanet
$ captplanet setup
$ captplanet run
```
Configuration is placed by default in `~/.storj/capt/`
Other changes:
* introduces new config structs for currently existing
Responsibilities that conform to the new Responsibility
interface. Please see the `pkg/*/config.go` files for
examples.
* integrates the PointerDB API key with other global
configuration via flags, instead of through environment
variables through viper like it's been doing. (ultimately
this should also change to use the PointerDB config
struct but this is an okay shortterm solution).
* changes the Overlay cache to use a URL for database
configuration instead of separate redis and bolt config
settings.
* stubs out some peer identity skeleton code (but not the
meat).
* Fixes the SegmentStore to use the overlay client and
pointerdb clients instead of gRPC client code directly
* Leaves a very clear spot where we need to tie the object to
stream to segment store together. There's sort of a "golden
spike" opportunity to connect all the train tracks together
at the bottom of pkg/miniogw/config.go, labeled with a
bunch of TODOs.
Future stuff:
* I now prefer this design over the original
pkg/process.Service thing I had been pushing before (sorry!)
* The experience of trying to have multiple farmers
configurable concurrently led me to prefer config structs
over global flags (I finally came around) or using viper
directly. I think global flags are okay sometimes but in
general going forward we should try and get all relevant
config into config structs.
* If you all like this direction, I think we can go delete my
old Service interfaces and a bunch of flags and clean up a
bunch of stuff.
* If you don't like this direction, it's no sweat at all, and
despite how much code there is here I'm not very tied to any
of this! Considering a lot of this was written between midnight
and 6 am, it might not be any good!

Responsibilities:
* Kademlia
* OverlayCache
* PointerDB
* StatDB
* PieceStore
* etc.
A Provider is a collection of Responsibilities that
share an Identity, such as:
* The heavy client
* The farmer
* The gateway
An Identity is a public/private key pair, a node id, etc.
Farmers all need different Identities, so captplanet
needs to support running multiple concurrent Providers
with different Identities.
Each Responsibility and Provider should allow for configuration
of multiple copies on its own so creating Responsibilities and
Providers use a new workflow.
To make a Responsibility, one should create a "config"
struct, such as:
```
type Config struct {
RepairThreshold int `help:"If redundancy falls below this number of
pieces, repair is triggered" default:"30"`
SuccessThreshold int `help:"If redundancy is above this number then
no additional uploads are needed" default:"40"`
}
```
To use "config" structs, this changeset introduces another
new library called 'cfgstruct', which allows for the configuration
of arbitrary structs through flagsets, and thus through cobra and
viper.
cfgstruct relies on Go's "struct tags" feature to document
help information and default values. Config structs can be
configured via cfgstruct.Bind for binding the struct to a flagset.
Because this configuration system makes setup and configuration
easier *in general*, additional commands are provided that allow
for easy standup of separate Providers. Please make sure to
check out:
* cmd/captplanet/farmer/main.go (a new farmer binary)
* cmd/captplanet/hc/main.go (a new heavy client binary)
* cmd/captplanet/gw/main.go (a new minio gateway binary)
Usage:
```
$ go install -v storj.io/storj/cmd/captplanet
$ captplanet setup
$ captplanet run
```
Configuration is placed by default in `~/.storj/capt/`
Other changes:
* introduces new config structs for currently existing
Responsibilities that conform to the new Responsibility
interface. Please see the `pkg/*/config.go` files for
examples.
* integrates the PointerDB API key with other global
configuration via flags, instead of through environment
variables through viper like it's been doing. (ultimately
this should also change to use the PointerDB config
struct but this is an okay shortterm solution).
* changes the Overlay cache to use a URL for database
configuration instead of separate redis and bolt config
settings.
* stubs out some peer identity skeleton code (but not the
meat).
* Fixes the SegmentStore to use the overlay client and
pointerdb clients instead of gRPC client code directly
* Leaves a very clear spot where we need to tie the object to
stream to segment store together. There's sort of a "golden
spike" opportunity to connect all the train tracks together
at the bottom of pkg/miniogw/config.go, labeled with a
bunch of TODOs.
Future stuff:
* I now prefer this design over the original
pkg/process.Service thing I had been pushing before (sorry!)
* The experience of trying to have multiple farmers
configurable concurrently led me to prefer config structs
over global flags (I finally came around) or using viper
directly. I think global flags are okay sometimes but in
general going forward we should try and get all relevant
config into config structs.
* If you all like this direction, I think we can go delete my
old Service interfaces and a bunch of flags and clean up a
bunch of stuff.
* If you don't like this direction, it's no sweat at all, and
despite how much code there is here I'm not very tied to any
of this! Considering a lot of this was written between midnight
and 6 am, it might not be any good!
* bind tests

type NodeSelectionConfig struct {
satellite/overlay: configurable meaning of last_net
Up to now, we have been implementing the DistinctIP preference with code
in two places:
1. On check-in, the last_net is determined by taking the /24 or /64
(in ResolveIPAndNetwork()) and we store it with the node record.
2. On node selection, a preference parameter defines whether to return
results that are distinct on last_net.
It can be observed that we have never yet had the need to switch from
DistinctIP to !DistinctIP, or from !DistinctIP to DistinctIP, on the
same satellite, and we will probably never need to do so in an automated
way. It can also be observed that this arrangement makes tests more
complicated, because we often have to arrange for test nodes to have IP
addresses in different /24 networks (a particular pain on macOS).
Those two considerations, plus some pending work on the repair framework
that will make repair take last_net into consideration, motivate this
change.
With this change, in the #2 place, we will _always_ return results that
are distinct on last_net. We implement the DistinctIP preference, then,
by making the #1 place (ResolveIPAndNetwork()) more flexible. When
DistinctIP is enabled, last_net will be calculated as it was before. But
when DistinctIP is _off_, last_net can be the same as address (IP and
port). That will effectively implement !DistinctIP because every
record will have a distinct last_net already.
As a side effect, this flexibility will allow us to change the rules
about last_net construction arbitrarily. We can do tests where last_net
is set to the source IP, or to a /30 prefix, or a /16 prefix, etc., and
be able to exercise the production logic without requiring a virtual
network bridge.
This change should be safe to make without any migration code, because
all known production satellite deployments use DistinctIP, and the
associated last_net values will not change for them. They will only
change for satellites with !DistinctIP, which are mostly test
deployments that can be recreated trivially. For those satellites which
are both permanent and !DistinctIP, node selection will suddenly start
acting as though DistinctIP is enabled, until the operator runs a single
SQL update "UPDATE nodes SET last_net = last_ip_port". That can be done
either before or after deploying software with this change.
I also assert that this will not hurt performance for production
deployments. It's true that adding the distinct requirement to node
selection makes things a little slower, but the distinct requirement is
already present for all production deployments, and they will see no
change.
