Thank you very much, everything's working as intended :)
from ijson.
@MKuranowski thanks for reporting. I can locally reproduce too, which is good (in a way!), but oddly it didn't happen with the unit tests. I'll have to study a bit closer what's going on.
from ijson.
Found the problems (there were two actually), both of course in the yajl2_c
backend only:
- There was an issue if the first call to
await f.read()
resulted on a yield to the scheduler. This wasn't caught by our unit tests because the simple class we use for testing doesn't yield execution whenread
is called. After adding anawait asyncio.sleep(0)
in there the unit tests starting failing in the same way your test script does. This is now fixed, and I pushed the fix to themaster
branch. - After fixing that, a second problem came up. This one has to do with the fact that
aiofiles
implements theread
operation (and most of them, I think) using@types.coroutines
decorations rather thanasync def
function definitions. The ijson C code wasn't prepared for that case (they are intrinsically different at this level), and I'll need to have a closer inspection yet into how to properly support both. I have something that seems to be working, but is still not fully stable, so I'd rather not push that fix yet.
I don't think I'll be able to tackle this second until early next week though. In the meanwhile you can workaround this by defining your own thin wrapper around aiofiles.open
so it defines an async def read
coroutine, that should work.

I just pushed the last set of changes to the master
branch that fix the second problem (correctly dealing with @type.coroutine
awaitable read
functions in the C backend), plus a new set of unit tests that ensure this will not creep up again. @MKuranowski please give this a try to confirm that things are working as intended.
A new release will follow probably tomorrow, time permitting.

A new 3.1.1 release of ijson including these fixes is now available on PyPI.
