# Python Agent

### Usage
Python traceable agent requires Python >= 3.6

Additionally, to use the traceable filter, you must be on a supported OS. 
- Ubuntu 18.04+
- Centos 7+
- Debian 10+
- Amazon Linux 2+

### Instrumentation methods
There are two ways to instrument your application, auto-instrumentation and code based instrumentation.

#### Autoinstrumentation
Simply prepend `traceableai-instrument` to your applications startup command.

ex: `traceableai-instrument flask run`


#### Code based instrumentation
Add the following snippet to your python apps entrypoint file:
```python
from traceableai.agent import Agent

app = Flask(__name__)

agent = Agent()
agent.instrument(app) # This will instrument the flask app + any other modules that are supported
agent.add_traceable_filter() # add the traceable filter to enable blocking
```

### Developing
```bash
# Create a virtual env & install dependencies
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt -r dev-requirements 
```

_Note: if you run into an error installing grpc:_
> File "/Users/user/.pyenv/versions/3.9.4/lib/python3.9/distutils/unixccompiler.py", line 120, in _compile
> raise CompileError(msg)
> distutils.errors.CompileError: command '/usr/bin/clang' failed with exit code 1

_prepend this env var to the above pip install command:_ 
`GRPC_PYTHON_BUILD_SYSTEM_ZLIB=true`

### Building
```bash
pip install -r requirements.txt
python3 -m build
```

### Instrumenting
```bash
traceableai-instrument your_startup_command
# ex: traceableai-instrument flask run -p 5000 
```

### Updating Libtraceable
When you want to update libtraceable you should first download the latest version and precompile the headers. 
```gcc -E libtraceable.h > libtraceable.h.preprocessed```

Then `mv libtraceable.h.preprocessed ./src/traceableai/filter/libtraceable.h.preprocessed`

Additionally, open `src/download.py`
Edit the constant: `LIBTRACEABLE_VERSION` set it equal to the version you just generated headers for.


You can test this functionality by using the project within the: `docker/test_apps`
It will fail to build if libtraceable cannot be downloaded

### Updating the Proto
```bash
git submodule update --init --recursive
./scripts/build_proto.sh
```
### Unit Tests
build_artifacts.sh builds all the whl files. Specify skipped versions in (CIBW_SKIP) to only build 3.6 for unit tests. 
```
CIBW_SKIP="*37* *38* *39* *310*" ./build_artifacts.sh
docker build --build-arg ARTIFACTORY_USER --build-arg ARTIFACTORY_TOKEN -f docker/test_apps/Dockerfile.unittest -t pythonunittest . && docker run --rm pythonunittest
```
### Test applications
Refer to `docker/test_apps/` and the corresponding scripts in `scripts/`
