api.steemit.com: get_ops_in_block(2889020, false) times out

[sneak]

Apologies if this bug is in the wrong repo; it may be a jussi/redis issue as I am testing against api.steemit.com.

This API call consistently fails, however fetching the block just before it or the block just after it works fine.

http -j post https://api.steemit.com jsonrpc=2.0 id=1 method=condenser_api.get_ops_in_block params:='[2889020, false]'

Note that this is a blocking issue that prevents my client from fully downloading the operations of the blockchain up to last_irreversible and thus my local db fails to sync and my app can't function.

[mvandeberg]

IIRC, this is a hardfork block that contains a large number of virtual ops. The call works directly against a steemd node. This fix this on api.steemit.com, Jussi should have an increased timeout on this call and cache this call for an extended period of time.

[mvandeberg]

As a workaround, I suggest calling condenser_api.get_block on this particular block as long as your app is not relying on virtual ops.

[sneak]

It does depend on virtual ops, so I'll wait for a fix in the service

[sneak]

Seems to work now with a bigger timeout. Thanks!

Fixed for 2889020, broken for 26038153 however - reopening.

I thought this kind of thing was fixed in jussi config, not steemd. Please note, the entire list of blocks that might need a bigger timeout is right here:

Edit: Well, I thought it was the entire list. But it's missing 2889020. :p
