EventSubmition & EventSubmitionRule domain struct

[elpiel]

https://github.com/AdExNetwork/adex-protocol/blob/master/campaignSpec.md#eventsubmission

EventSubmittion:

• allow: array of EventSubmissionRule; for each POST to /channel/:id/events, the first rule that matches will apply

EventSubmissionRule:

• uids: array of used IDs that this rule applies to; leave null for applying to everyone (note that subsequent rules in allow won't match); set to [null] to apply to requests without authentication
• rateLimit: optional, object describing the rate limit to apply; for, this takes { type: "ip", timeframe }, where timeframe is a number; later, { type: "uid", timeframe } will be added

Examples

{ allow: [{ uids: null, rateLimit: { type: "ip", timeframe: 1000 } }] } - this will allow everyone to submit events, at a rate of 1 event per second per IP

{ allow: [{ uids: [channel.creator] }, { uids: null, rateLimit: { type: "ip", timeframe: 1000 } }] } - this will allow the creator to submit as many events as they like, but everyone else will be restricted to 1 event per second per IP

• [x] add all fields
• [ ] create fixtures
• [ ] use fixture for ChannelSpec #24

@Ivshti can you elaborate on the EventSubmissionRule::uuids ? is the channel.creator the actual value of the Channel creator or it's a parameter of type Enum (channel.creator, validator.leader, validator.follower)?

[Ivshti]

does this help -> https://tom.adex.network/channel/list ?

it's an array of user IDs (where a user ID is of the same format as it is in channel.creator, validators, etc.; this format is an ethereum address, but should be represented as an arbitrary variable-length byte array because of flexibility; or a hex string)

Yep, this helps. Thanks.

[elpiel]

Closed #36 as we discussed we will just use String.

[elpiel]

What is the allowed timeframe range @Ivshti ? Also:

• Should empty uids & null uids be treated as NULL (aka None)?
• What if we have uids = null and rate_limit = null should we force one or the other in the Struct & in the deserilzation of the struct?

[elpiel]

As discussed with @Ivshti , having both uids & rate_limit to NULL, is a valid case. If we have: [rule1, rule2, rule3, {uids: null, rateLimit: null}] Everything that is not falling into rule1, rule2, rule3 is unlimited.

This case is valid and for that reason we will not force any checks atm.
