# uni-info-watcher
## Instructions
### Setup
Create a postgres12 database for the job queue:
```
sudo su - postgres
createdb uni-info-watcher-job-queue
```
Enable the `pgcrypto` extension on the job queue database (https://github.com/timgit/pg-boss/blob/master/docs/usage.md#intro).
Example:
```
postgres@tesla:~$ psql -U postgres -h localhost uni-info-watcher-job-queue
Password for user postgres:
psql (12.7 (Ubuntu 12.7-1.pgdg18.04+1))
SSL connection (protocol: TLSv1.3, cipher: TLS_AES_256_GCM_SHA384, bits: 256, compression: off)
Type "help" for help.
uni-watcher-job-queue=# CREATE EXTENSION pgcrypto;
CREATE EXTENSION
uni-info-watcher-job-queue=# exit
```
Create a postgres12 database for the uni-info watcher:
```
sudo su - postgres
createdb uni-info-watcher
```
Update `environments/local.toml` with database connection settings for both the databases.
### Run
* Build files:
```bash
$ yarn build
```
* Start the server:
```bash
$ yarn server
# For development.
$ yarn server:dev
# For specifying config file.
$ yarn server -f environments/local.toml
```
* Start the job runner:
```bash
$ yarn job-runner
# For development.
$ yarn job-runner:dev
# For specifying config file.
$ yarn job-runner -f environments/local.toml
```
* Run `yarn server:mock` to run server with mock data.

## Scripts
* **generate:schema**
Generate schema for uniswap subgraph in graphql format. The `get-graphql-schema` tool is used to generate the schema (https://github.com/prisma-labs/get-graphql-schema). The uniswap subgraph graphql endpoint is provided in the script to generate the schema.
* **lint:schema**
Lint schema graphql files:
```bash
$ yarn lint:schema docs/analysis/schema/frontend.graphql
```
## Test
### Smoke test
To run a smoke test:
* Start the server in `packages/erc-20-watcher`.
* Start the server and the job-runner in `packages/uni-watcher`.
* Start the server and the job-runner in `packages/uni-info-watcher`.
* Run the smoke test in `packages/uni-watcher` atleast once.
* Run:
```bash
$ yarn smoke-test
```

# Design Notes
## Watchers
* uniswap-watcher
* Provides events to downstream subscribers, access to core/periphery contract data,
* uniswap-info-watcher
* Subscribes to uniswap-watcher
* Performs computation/derivation of entity properties required by info frontend
* Filler (old to new block)
## Issues
* Filler should process block by block (old to new) starting from contract deployment block
* Otherwise, values of computed props will be incorrect
* "last_processed_block_number"
* Use audit/proof table to record changes to entities instead of aggregating in code (too slow)
* Handling reorgs
* ERC20 variants (storage layout)

## Hierarchical Queries
For fetching previous entity that would be updated at a particular blockHash, we need to traverse the parent hashes. As the same entity might be present on a different branch chain with different values. These branches occur in the frothy region and so a recursive query is done to get the blockHash of the previous entity in this region.
Let the blockHash be `0xBlockHash` and the entity id be `entityId`, then the hierarchical query is
```pgsql
WITH RECURSIVE cte_query AS
(
SELECT
b.block_hash,
b.block_number,
b.parent_hash,
1 as depth,
e.id
FROM
block_progress b
LEFT JOIN
entityTable e ON e.block_hash = b.block_hash
WHERE
b.block_hash = '0xBlockHash'
UNION ALL
SELECT
b.block_hash,
b.block_number,
b.parent_hash,
c.depth + 1,
e.id
FROM
block_progress b
LEFT JOIN
${repo.metadata.tableName} e
ON e.block_hash = b.block_hash
AND e.id = 'entityId'
INNER JOIN
cte_query c ON c.parent_hash = b.block_hash
WHERE
c.id IS NULL AND c.depth < 16
)
SELECT
block_hash, block_number, id
FROM
cte_query
ORDER BY block_number ASC
LIMIT 1;
```
The second WHERE clause checks that the loop continues only till MAX_REORG_DEPTH `16` which specifies the frothy region or stop when the entity is found.
The resulting blockHash is then used to fetch the previous entity.
For fetching multiple entities, we fetch all the blockHashes in the frothy region. So it fetches the entities from the correct branch in the frothy and then from the pruned region.
Hierarchical query for getting blockHashes in the frothy region
```pgsql
WITH RECURSIVE cte_query AS
(
SELECT
block_hash,
block_number,
parent_hash,
1 as depth
FROM
block_progress
WHERE
block_hash = '0xBlockHash'
UNION ALL
SELECT
b.block_hash,
b.block_number,
b.parent_hash,
c.depth + 1
FROM
block_progress b
INNER JOIN
cte_query c ON c.parent_hash = b.block_hash
WHERE
c.depth < 16
)
SELECT
block_hash, block_number
FROM
cte_query;
```

# Uniswap Watcher
## Setup
Create a postgres12 database for the job queue:
```
sudo su - postgres
createdb uni-watcher-job-queue
```
Enable the `pgcrypto` extension on the job queue database (https://github.com/timgit/pg-boss/blob/master/docs/usage.md#intro).
Example:
```
postgres@tesla:~$ psql -U postgres -h localhost uni-watcher-job-queue
Password for user postgres:
psql (12.7 (Ubuntu 12.7-1.pgdg18.04+1))
SSL connection (protocol: TLSv1.3, cipher: TLS_AES_256_GCM_SHA384, bits: 256, compression: off)
Type "help" for help.
uni-watcher-job-queue=# CREATE EXTENSION pgcrypto;
CREATE EXTENSION
uni-watcher-job-queue=# exit
```
Create a postgres12 database for the address watcher:
```
sudo su - postgres
createdb uni-watcher
```
Update `environments/local.toml` with database connection settings for both the databases.
## Run
Build files:
```bash
$ yarn build
```
Run the server:
```bash
$ yarn server
# For development.
$ yarn server:dev
# For specifying config file.
$ yarn server -f environments/local.toml
```
Start the job runner:
```bash
$ yarn job-runner
# For development.
$ yarn job-runner:dev
# For specifying config file.
$ yarn job-runner -f environments/local.toml
```
Start watching the factory contract:
```bash
$ yarn watch:contract --address 0xContractAddress --kind <contract-kind> --startingBlock <start-block>
# For specifying config file.
$ yarn watch:contract -f environments/local.toml --address 0xContractAddress --kind <contract-kind> --startingBlock <start-block>
```
Example:
```bash
$ yarn watch:contract --address 0xfE0034a874c2707c23F91D7409E9036F5e08ac34 --kind factory --startingBlock 100
```
Start watching the NonFungiblePositionManager contract:
Example:
```bash
$ yarn watch:contract --address 0xB171168C0df9457Ff3E3D795aE25Bf4f41e2FFE3 --kind nfpm --startingBlock 100
```
To fill a block range:
```bash
yarn fill --startBlock <from-block> --endBlock <to-block>
# For specifying config file.
$ yarn fill -f environments/local.toml --startBlock <from-block> --endBlock <to-block>
```
Example:
```bash
$ yarn fill --startBlock 1000 --endBlock 2000
```
## Test
To test the watchers locally:
* Deploy the Uniswap contracts
* Watch the Factory and NonFungiblePositionManager contracts
* Send transactions to trigger events
See https://github.com/vulcanize/uniswap-v3-periphery/blob/watcher-ts/demo.md for instructions.
### Smoke test
To run a smoke test:
* Start the server and the job-runner.
* To build contracts for tests, run the command below in root of the repository:
```bash
$ yarn build:contracts
```
* Run:
```bash
$ yarn smoke-test
```
