bug: OverflowError: Python int too large to convert to C int

[mikeshultz]

Seen just now on sepolia. Will see about instrumenting more tomorrow:

OverflowError: Python int too large to convert to C int

Alright, found a (the?) stream that triggers this error on Sepolia:

• creator: 0x588eBB657Ca52d6fbDf8F52C760D53C1474e37Ed
• stream_id: 54
• time_left: 9999999999229756

It appears that it's not even a large amount of tokens, but a very small amount_per_second causing the issue:

>>> now = int(datetime.utcnow().timestamp())
>>> last_pull = 1697577384
>>> funded_amount = 1000000000008640000
>>> amount_per_second = 100
>>> amount_unlocked = min((now - last_pull) * amount_per_second, funded_amount)
>>> amount_unlocked
87882700
>>> (funded_amount - amount_unlocked) / amount_per_second
9999999999207572.0
>>> int(9999999999207572.0)
9999999999207572
>>> timedelta(seconds=9999999999207572)
Traceback (most recent call last):

OverflowError: Python int too large to convert to C int

So it seems to be a limitation in timedelta. Which honestly is fair, because this stream is funded for over 317 million years.

yeah, so like... probably should just raise, since that's unlikely to be a legitimate time to use
