RPC: Improve error messages on RPC endpoints that use GetTransaction by jimpo · Pull Request #13144 · bitcoin/bitcoin

jimpo · 2018-05-01T23:56:02Z

This contains some follow up items from #13033.

The PR refactors the GetTransaction function and moves it from validation to rpc/rawtransaction. This breaks a cyclic dependency between validation and index/txindex pointed out by @sipa. Also, the REST transaction API and gettxoutproof RPC now have more clear error messages when the txindex is not available, as requested by @TheBlueMatt.

This would also be a good opportunity to drop the slow tx lookup through the unspent coins view if people are for it, as proposed in #3220.

F841 local variable 'prevout_index' is assigned to but never used

Same error on two of the linux builds:

Some comments.

... without -txindex.?

promag · 2018-05-13T10:46:22Z

IMO this could be removed (lines 193 to 200), does't test error messages.

The purpose of the assertion on line 199 is to test that the error received on 192 goes away after transaction is in the mempool.

Right, a comment there would be nice then, like:

# No error should be raised now that the transaction is known.

promag · 2018-05-13T10:48:03Z

nit, could put allow_slow after tx_hash.

promag · 2018-05-13T10:51:27Z

nit s/status/state.

Needs rebase

jb55 · 2018-07-15T18:15:38Z

Concept ACK, checked and it rebases cleanly

The error messages now indicate the status of the txindex.

This breaks a circular dependency between validation and txindex.

Break out GetTransactionInBlock into a separate method.

Since both the REST and RPC APIs use GetTransaction, there is no need to duplicate the error handling logic.

Needs rebase

DrahtBot · 2018-10-28T13:44:58Z

There hasn't been much activity lately and the patch still needs rebase, so I am closing this for now. Please let me know when you want to continue working on this, so the pull request can be re-opened.
