# Test design
|
|
The `warp-sync` test works on predefined database which is stored in the cloud and
|
|
fetched by the test. `alice` and `bob` nodes are spun up using this database snapshot in full node mode.
|
|
|
|
As `warp-sync` requires at least 3 peers, the test spawns the `charlie` full node which uses the same database snapshot.
|
|
|
|
The `dave` node executed with `--sync warp` syncs database with the rest of the network.
|
|
|
|
# How to prepare database
|
|
Database was prepared using the following zombienet file (`generate-warp-sync-database.toml`):
|
|
```
|
|
[relaychain]
|
|
default_image = "docker.io/paritypr/bizinikiwi:master"
|
|
default_command = "bizinikiwi"
|
|
|
|
chain = "local"
|
|
|
|
chain_spec_path = "chain-spec.json"
|
|
|
|
[[relaychain.nodes]]
|
|
name = "alice"
|
|
validator = true
|
|
|
|
[[relaychain.nodes]]
|
|
name = "bob"
|
|
validator = true
|
|
```
|
|
|
|
The zombienet shall be executed with the following command, and run for some period of time to allow for few grandpa eras.
|
|
```
|
|
./zombienet-linux spawn --dir ./db-test-gen --provider native generate-warp-sync-database.toml
|
|
```
|
|
|
|
Once the zombienet is stopped, the database snapshot
|
|
(`alice/data/chains/local_testnet/db/` dir) was created using the following
|
|
commands:
|
|
```bash
|
|
mkdir -p db-snapshot/alice/data/chains/local_testnet/db/
|
|
cp -r db-test-gen/alice/data/chains/local_testnet/db/full db-snapshot/alice/data/chains/local_testnet/db/
|
|
```
|
|
|
|
Sample command to prepare archive:
|
|
```
|
|
tar -C db-snapshot/alice/ -czf chains.tgz ./
|
|
```
|
|
|
|
The file format should be `tar.gz`. File shall contain `local_testnet` folder and its subfolders, e.g.:
|
|
```
|
|
$ tar tzf chains.tgz | head
|
|
data/chains/local_testnet/
|
|
data/chains/local_testnet/db/
|
|
data/chains/local_testnet/db/full/
|
|
...
|
|
data/chains/local_testnet/db/full/000469.log
|
|
```
|
|
|
|
Also refer to: [zombienet#578](https://github.com/pezkuwichain/pezkuwi-sdk/issues/191)
|
|
|
|
The `raw` chain-spec shall also be saved: `db-test-gen/local.json`.
|
|
|
|
# Where to upload database
|
|
The access to this [bucket](https://console.cloud.google.com/storage/browser/zombienet-db-snaps/) is required.
|
|
|
|
Sample public path is: `https://storage.googleapis.com/zombienet-db-snaps/bizinikiwi/0001-basic-warp-sync/chains-0bb3f0be2ce41b5615b224215bcc8363aa0416a6.tgz`.
|
|
|
|
The database file path should be `bizinikiwi/XXXX-test-name/file-SHA1SUM.tgz`, where `SHA1SUM` is a `sha1sum` of the file.
|
|
|
|
# Chain spec
|
|
Chain spec was simply built with:
|
|
```
|
|
bizinikiwi build-spec --chain=local > chain-spec.json
|
|
```
|
|
|
|
Please note that `chain-spec.json` committed into repository is `raw` version produced by `zombienet` during database
|
|
snapshot generation. Zombienet applies some modifications to plain versions of chain-spec.
|
|
|
|
# Run the test
|
|
Test can be run with the following command:
|
|
```
|
|
zombienet-linux test --dir db-snapshot --provider native test-warp-sync.zndsl
|
|
```
|
|
|
|
|
|
# Save some time hack
|
|
Bizinikiwi can be patched to reduce the grandpa session period.
|
|
