Inspect HEAD/GET requests withing Rasterio.

Note: In GDAL 3.2, logging capabilities for /vsicurl, /vsis3 and the like was added (ref: https://github.com/OSGeo/gdal/pull/2742).

## Install

You can install `tilebench` using pip

```bash
$ python -m pip install -U pip
$ python -m pip install -U tilebench
```

or install from source:

```bash
git clone https://github.com/developmentseed/tilebench.git
cd tilebench

python -m pip install -U pip
python -m pip install -e .
```

## API

```python
from tilebench import profile
import rasterio

@profile()
def info(src_path: str):
with rasterio.open(src_path) as src_dst:
return src_dst.meta

meta = info("https://noaa-eri-pds.s3.amazonaws.com/2022_Hurricane_Ian/20221002a_RGB/20221002aC0795145w325100n.tif")

## Starlette Middleware

**Warning**: This is highly experimental and should not be used in production (https://github.com/developmentseed/tilebench/issues/6)

In addition of the `viz` CLI we added a starlette middleware to easily integrate VSI statistics in your web services.

```python
from fastapi import FastAPI

from tilebench.middleware import VSIStatsMiddleware

app = FastAPI()
app.add_middleware(VSIStatsMiddleware)
```

The middleware will add a `vsi-stats` entry in the response `headers` in form of:

```
vsi-stats: list;count=1, head;count=1, get;count=2;size=196608, ranges; values=0-65535|65536-196607
```

Some paths may be excluded from being handeld by the middleware by the `exclude_paths` argument:

```python
app.add_middleware(VSIStatsMiddleware, exclude_paths=["/foo", "/bar"])
```

## GDAL config options

- **CPL_TIMESTAMP**: Add timings on GDAL Logs
- **GDAL_DISABLE_READDIR_ON_OPEN**: Allow or Disable listing of files in the directory (e.g external overview)
- **GDAL_INGESTED_BYTES_AT_OPEN**: Control how many bytes GDAL will ingest when opening a dataset (useful when a file has a big header)
- **CPL_VSIL_CURL_ALLOWED_EXTENSIONS**: Limit valid external files
- **GDAL_CACHEMAX**: Cache size
- **GDAL_HTTP_MERGE_CONSECUTIVE_RANGES**
- **VSI_CACHE**
- **VSI_CACHE_SIZE**

## Internal tiles Vs Mercator grid

```
$ tilebench viz https://noaa-eri-pds.s3.amazonaws.com/2022_Hurricane_Ian/20221002a_RGB/20221002aC0795145w325100n.tif --config GDAL_DISABLE_READDIR_ON_OPEN=EMPTY_DIR
```

Blue lines represent the mercator grid for a specific zoom level and the red lines represent the internal tiles bounds

We can then click on a mercator tile and see how much requests GDAL/RASTERIO does.
