For macOS, you can reference this [guide](http://tldrdevnotes.com/bash-upgrade-3-4-macos). For Linux, you can reference this [guide](https://fossbytes.com/installing-gnu-bash-4-4-linux-distros/).
|
|
|
|
## Dev Environment
|
|
|
|
**Most repos from [harmony-one](https://github.com/harmony-one) assumes the GOPATH convention. More information [here](https://github.com/golang/go/wiki/GOPATH).**
|
|
|
|
### First Install
|
|
Clone and set up all of the repos with the following set of commands:
|
|
|
|
1. Create the appropriate directories:
|
|
```bash
|
|
mkdir -p $(go env GOPATH)/src/github.com/harmony-one
|
|
cd $(go env GOPATH)/src/github.com/harmony-one
|
|
```
|
|
> If you get 'unknown command' or something along those lines, make sure to install [golang](https://golang.org/doc/install) first.
|
|
|
|
2. Clone this repo & dependent repos.
|
|
```bash
|
|
git clone https://github.com/harmony-one/mcl.git
|
|
git clone https://github.com/harmony-one/bls.git
|
|
git clone https://github.com/harmony-one/harmony.git
|
|
cd harmony
|
|
```
|
|
|
|
3. Build the harmony binary & dependent libs
|
|
```
|
|
make
|
|
```
|
|
> Run `bash scripts/install_build_tools.sh` to ensure build tools are of correct versions.
|
|
|
|
## Dev Docker Image
|
|
|
|
Included in this repo is a Dockerfile that has a full harmony development environment and
|
|
comes with emacs, vim, ag, tig and other creature comforts. Most importantly, it already has the go environment
|
|
with our C/C++ based library dependencies (`libbls` and `mcl`) set up correctly for you.
|
|
|
|
You can build the docker image for yourself with the following commands:
|
|
```bash
|
|
cd $(go env GOPATH)/src/github.com/harmony-one/harmony
|
|
make clean
|
|
docker build -t harmony .
|
|
```
|
|
|
|
Then you can start your docker container with the following command:
|
|
```bash
|
|
docker rm harmony # Remove old docker container
|
|
docker run --name harmony -it -v "$(go env GOPATH)/src/github.com/harmony-one/harmony:/root/go/src/github.com/harmony-one/harmony" harmony /bin/bash
|
|
```
|
|
> Note that the harmony repo will be shared between your docker container and your host machine. However, everything else in the docker container will be ephemeral.
|
|
|
|
If you need to open another shell, just do:
|
|
```bash
|
|
docker exec -it harmony /bin/bash
|
|
```
|
|
|
|
Learn more about docker [here](https://docker-curriculum.com/).
|
|
|
|
## Build
|
|
|
|
The `make` command should automatically build the Harmony binary & all dependent libs.
|
|
|
|
However, if you wish to bypass the Makefile, first export the build flags:
|
|
```bash
|
|
export CGO_CFLAGS="-I$GOPATH/src/github.com/harmony-one/bls/include -I$GOPATH/src/github.com/harmony-one/mcl/include -I/usr/local/opt/openssl/include"
|
|
export CGO_LDFLAGS="-L$GOPATH/src/github.com/harmony-one/bls/lib -L/usr/local/opt/openssl/lib"
|
|
export LD_LIBRARY_PATH=$GOPATH/src/github.com/harmony-one/bls/lib:$GOPATH/src/github.com/harmony-one/mcl/lib:/usr/local/opt/openssl/lib
|
|
export LIBRARY_PATH=$LD_LIBRARY_PATH
|
|
export DYLD_FALLBACK_LIBRARY_PATH=$LD_LIBRARY_PATH
|
|
export GO111MODULE=on
|
|
```
|
|
|
|
Then you can build all executables with the following command:
|
|
```bash
|
|
bash ./scripts/go_executable_build.sh -S
|
|
```
|
|
> Reference `bash ./scripts/go_executable_build.sh -h` for more build options
|
|
|
|
## Debugging
|
|
|
|
One can start a local network (a.k.a localnet) with your current code using the following command:
|
|
```bash
|
|
make debug
|
|
```
|
|
> This localnet has 2 shards, with 11 nodes on shard 0 (+1 explorer node) and 10 nodes on shard 0 (+1 explorer node).
|
|
>
|
|
> The shard 0 endpoint will be on the explorer at `http://localhost:9599`. The shard 1 endpoint will be on the explorer at `http://localhost:9598`.
|
|
>
|
|
> You can view the localnet configuration at `/test/configs/local-resharding.txt`. The fields for the config are (space-delimited & in order) `ip`, `port`, `mode`, `bls_pub_key`, and `shard` (optional).
|
|
|
|
One can force kill the local network with the following command:
|
|
```bash
|
|
make debug-kill
|
|
```
|
|
> You can view all make commands with `make help`
|
|
|
|
## Testing
|
|
|
|
To keep things consistent, we have a docker image to run all tests. **These are the same tests ran on the pull request checks**.
|
|
|
|
Note that all testing docker container binds a couple of ports to the host machine for your convince. The ports are:
|
|
* `9500` - Shard 0 RPC for a validator
|
|
* `9501` - Shard 1 RPC for a validator
|
|
* `9599` - Shard 0 RPC for an explorer
|
|
* `9598` - Shard 1 RPC for an explorer
|
|
* `9799` - Shard 0 Rosetta (for an explorer)
|
|
* `9798` - Shard 1 Rosetta (for an explorer)
|
|
* `9899` - Shard 0 WS for an explorer
|
|
* `9898` - Shard 1 WS for an explorer
|
|
> This allows you to use curl, hmy CLI, postman, rosetta-cli, etc... on your host machine to play with or probe the localnet that was used for the test.
|
|
|
|
### Go tests
|
|
To run this test, do:
|
|
```bash
|
|
make test-go
|
|
```
|
|
This test runs the go tests along with go lint, go fmt, go imports, go mod, and go generate checks.
|
|
|
|
### RPC tests
|
|
To run this test, do:
|
|
```bash
|
|
make test-rpc
|
|
```
|
|
This test starts a localnet (within the Docker container), **ensures it reaches a consensus**, and runs a series of tests to ensure correct RPC behavior.
|
|
This test also acts as a preliminary integration test (more through tests are done on the testnets).
|
|
> The tests ran by this command can be found [here](https://github.com/harmony-one/harmony-test/tree/master/localnet).
|
|
|
|
If you wish to debug further with the localnet after the tests are done, open a new shell and run:
|
|
```bash
|
|
make test-rpc-attach
|
|
```
|
|
> This will open a shell in the docker container that is running the Node API tests.
|
|
>
|
|
> Note that the docker container has the [Harmony CLI](https://docs.harmony.one/home/wallets/harmony-cli) on path,
|
|
> therefore you can use that to debug if needed. For example, one could do `hmy blockchain latest-headers` to check
|
|
> the current block height of localnet. Reference the documentation for the CLI [here](https://docs.harmony.one/home/wallets/harmony-cli)
|
|
> for more details & commands.
|
|
|
|
### Rosetta tests
|
|
To run this test, do:
|
|
```bash
|
|
make test-rosetta
|
|
```
|
|
This test starts a localnet (within the Docker container), **ensures it reaches a consensus**, and runs the Construction & Data API checks using the [rosetta-cli](https://github.com/coinbase/rosetta-cli).
|
|
This test also acts as a preliminary integration test (more through tests are done on the testnets).
|
|
> The config for this test can be found [here](https://github.com/harmony-one/harmony-test/blob/master/localnet/configs/localnet_rosetta_test_s0.json) & [here](https://github.com/harmony-one/harmony-test/blob/master/localnet/configs/localnet_rosetta_test_s1.json)
|
|
|
|
Similar to the RPC tests, if you wish to debug further with the localnet after the tests are done, open a new shell and run:
|
|
```bash
|
|
make test-rosetta-attach
|
|
```
