That is not a segfault. The problem I am reporting is a segfault.
It can be reproduced with uvicorn as follow:
from lsm import LSM
db = LSM('db.sqlite')
async def app(scope, receive, send):
assert scope['type'] == 'http'
global db
for (index, (key, value)) in enumerate(db[b'\x00':b'\xFF']):
pass
await send({
'type': 'http.response.start',
'status': 200,
'headers': [
[b'content-type', b'text/plain'],
],
})
await send({
'type': 'http.response.body',
'body': b'Hello, world!',
})
db.close()
Run the above program with: python -X dev -m uvicorn bobo:app
Then in another console: curl http://localhost:8000/
Here is the output:
$ python -X dev -m uvicorn bobo:app
INFO: Started server process [3580316]
INFO: Waiting for application startup.
INFO: ASGI 'lifespan' protocol appears unsupported.
INFO: Application startup complete.
