# asv_bench_memray

This a proof-of-concept externally defined `memray` **benchmark plugin** for `asv`.

## Usage

In your `asv.conf.json` add the following to the requirements matrix:

``` json-with-comments
"matrix": {
    "req": {
        "numpy": ["1.21"],
        "asv_plugin_memray": [""]
    },
},
```

This should be enough for an example like the following to run:

``` python
import numpy as np

class MyBenchmark:
    params = [10, int(2e4)]

    def ray_sum(self, n):
        self.data = np.random.rand(n)
        np.sum(self.data)
```

Which should result in something roughly like:

```sh
ASV_RUNNER_PATH="../asv_runner" asv run --bench sum

```

## Development

During development, one needs to pass a relative path:

``` json-with-comments
"matrix": {
    "req": {
        "asv_bench_memray": ["../asv_bench_memray"]
    },
},
```

Also it may be necessary to cleanup older environments and explicitly point to an instance of `asv_runner`:

``` sh
rm -rf .asv && ASV_RUNNER_PATH="../asv_runner" asv run --bench sum
```

Personally I keep benchmarks for testing at an [experiments repo](https://github.com/HaoZeke/asv_experiments), but any local test will do.

### Conventions

Like all externally defined benchmark plugins for `asv`, this has a strict hierarchy.
- [X] The package name begins with `asv_bench`
- [X] Benchmarks are defined in a `benchmarks` folder under the package module
- [X] Each exported new benchmark type has the `export_as_benchmark = [NAMEBenchmark]` attribute

For more conventions follow the documention of `asv_runner`.
