## Prerequisites
Running `lbrynet` from source requires Python 3.7. Get the installer for your OS [here](https://www.python.org/downloads/release/python-370/).
Running `lbrynet` from source requires Python 3.7 or higher. Get the installer for your OS [here](https://www.python.org/downloads/release/python-370/).
After installing Python 3.7, you'll need to install some additional libraries depending on your operating system.
Because of [issue #2769](https://github.com/lbryio/lbry-sdk/issues/2769)
at the moment the `lbrynet` daemon will only work correctly with Python 3.7.
If Python 3.8+ is used, the daemon will start but the RPC server
may not accept messages, returning the following:
```
Could not connect to daemon. Are you sure it's running?
```
After installing python 3, you'll need to install some additional libraries depending on your operating system.
### macOS
macOS users will need to install [xcode command line tools](https://developer.xamarin.com/guides/testcloud/calabash/configuring/osx/install-xcode-command-line-tools/) and [homebrew](http://brew.sh/).
These environment variables also need to be set:
```
PYTHONUNBUFFERED=1
EVENT_NOKQUEUE=1
```
1. PYTHONUNBUFFERED=1
2. EVENT_NOKQUEUE=1
Remaining dependencies can then be installed by running:
```
brew install python protobuf
```

On Ubuntu (16.04 minimum, we recommend 18.04), install the following:

sudo add-apt-repository ppa:deadsnakes/ppa

```
The [deadsnakes PPA](https://launchpad.net/~deadsnakes/+archive/ubuntu/ppa) provides Python 3.7
for those Ubuntu distributions that no longer have it in their
official repositories.
On Raspbian, you will also need to install `python-pyparsing`.
If you're running another Linux distro, install the equivalent of the above packages for your system.

### Linux/Mac
Clone the repository:
```bash
git clone https://github.com/lbryio/lbry-sdk.git
cd lbry-sdk
```
To install on Linux/Mac:
Create a Python virtual environment for lbry-sdk:
```bash
python3.7 -m venv lbry-venv
```
```
Clone the repository:
$ git clone https://github.com/lbryio/lbry-sdk.git
$ cd lbry-sdk
Activate virtual environment:
```bash
source lbry-venv/bin/activate
```
Create a Python virtual environment for lbry-sdk:
$ python3.7 -m venv lbry-venv
Activating lbry-sdk virtual environment:
$ source lbry-venv/bin/activate
Make sure you're on Python 3.7+ (as the default Python in virtual environment):
$ python --version
Make sure you're on Python 3.7+ as default in the virtual environment:
```bash
python --version
```
Install packages:
$ make install
Install packages:
```bash
make install
```
If you are on Linux and using PyCharm, generates initial configs:
$ make idea
```
If you are on Linux and using PyCharm, generates initial configs:
```bash
make idea
```
To verify your installation, `which lbrynet` should return a path inside
of the `lbry-venv` folder.
```bash
(lbry-venv) $ which lbrynet
/opt/lbry-sdk/lbry-venv/bin/lbrynet
```
To exit the virtual environment simply use the command `deactivate`.
To verify your installation, `which lbrynet` should return a path inside of the `lbry-venv` folder created by the `python3.7 -m venv lbry-venv` command.
### Windows
Clone the repository:
```bash
git clone https://github.com/lbryio/lbry-sdk.git
cd lbry-sdk
```
To install on Windows:
Create a Python virtual environment for lbry-sdk:
```bash
python -m venv lbry-venv
```
```
Clone the repository:
> git clone https://github.com/lbryio/lbry-sdk.git
> cd lbry-sdk
Activate virtual environment:
```bash
lbry-venv\Scripts\activate
```
Create a Python virtual environment for lbry-sdk:
> python -m venv lbry-venv
Install packages:
```bash
pip install -e .
```
Activating lbry-sdk virtual environment:
> lbry-venv\Scripts\activate
Install packages:
> pip install -e .
```
## Run the tests
### Elasticsearch
For running integration tests, Elasticsearch is required to be available at localhost:9200/
To run the unit tests from the repo directory:
The easiest way to start it is using docker with:
```bash
make elastic-docker
```
Alternative installation methods are available [at Elasticsearch website](https://www.elastic.co/guide/en/elasticsearch/reference/current/install-elasticsearch.html).
To run the unit and integration tests from the repo directory:
```
python -m unittest discover tests.unit
python -m unittest discover tests.integration
```
```
python -m unittest discover tests.unit
```
## Usage
To start the API server:
```
lbrynet start
```
`lbrynet start`
Whenever the code inside [lbry-sdk/lbry](./lbry)
is modified we should run `make install` to recompile the `lbrynet`
executable with the newest code.
## Development
When developing, remember to enter the environment,
and if you wish start the server interactively.
```bash
$ source lbry-venv/bin/activate
(lbry-venv) $ python lbry/extras/cli.py start
```
Parameters can be passed in the same way.
```bash
(lbry-venv) $ python lbry/extras/cli.py wallet balance
```
If a Python debugger (`pdb` or `ipdb`) is installed we can also start it
in this way, set up break points, and step through the code.
```bash
(lbry-venv) $ pip install ipdb
(lbry-venv) $ ipdb lbry/extras/cli.py
```
Happy hacking!

LBRY is a decentralized peer-to-peer protocol for publishing and accessing digital content. It utilizes the [LBRY blockchain](https://github.com/lbryio/lbrycrd) as a global namespace and database of digital content. Blockchain entries contain searchable content metadata, identities, rights and access rules. LBRY also provides a data network that consists of peers (seeders) uploading and downloading data from other peers, possibly in exchange for payments, as well as a distributed hash table used by peers to discover other peers.
LBRY SDK for Python is currently the most fully featured implementation of the LBRY Network protocols and includes many useful components and tools for building decentralized applications. Primary features and components include:
* Built on Python 3.7 and `asyncio`.
* Built on Python 3.7+ and `asyncio`.
* Kademlia DHT (Distributed Hash Table) implementation for finding peers to download from and announcing to peers what we have to host ([lbry.dht](https://github.com/lbryio/lbry-sdk/tree/master/lbry/dht)).
* Blob exchange protocol for transferring encrypted blobs of content and negotiating payments ([lbry.blob_exchange](https://github.com/lbryio/lbry-sdk/tree/master/lbry/blob_exchange)).
* Protobuf schema for encoding and decoding metadata stored on the blockchain ([lbry.schema](https://github.com/lbryio/lbry-sdk/tree/master/lbry/schema)).

Schema
=====
Those files are generated from the [types repo](https://github.com/lbryio/types). If you are modifying/adding a new type, make sure it is cloned in the same root folder as the SDK repo, like:
```
repos/
- lbry-sdk/
- types/
```
Then, [download protoc 3.2.0](https://github.com/protocolbuffers/protobuf/releases/tag/v3.2.0), add it to your PATH. On linux it is:
```bash
cd ~/.local/bin
wget https://github.com/protocolbuffers/protobuf/releases/download/v3.2.0/protoc-3.2.0-linux-x86_64.zip
unzip protoc-3.2.0-linux-x86_64.zip bin/protoc -d..
```
Finally, `make` should update everything in place.
### Why protoc 3.2.0?
Different/newer versions will generate larger diffs and we need to make sure they are good. In theory, we can just update to latest and it will all work, but it is a good practice to check blockchain data and retro compatibility before bumping versions (if you do, please update this section!).
