    Create a combinerawtransaction RPC which accepts a json array of hex raw transactions to combine them into one transaction. Signrawtransaction is changed to no longer combine transactions and only accept one transaction at a time.

    The tests have been updated to test this. Tests for the signrawtransaction merge have also been removed.

    This is part of #10570

    Concept ACK. However, this does break backward compatibility with an undocumented but apparently intentional and tested feature. Does this require deprecation first?

    Concept feedback: combining transactions seems like a utility. Is it possible to add it to bitcoin-tx rather than add a utility-only RPC?
  9. sipa commented at 2:56 pm on June 28, 2017: member
    It is not a utility-only RPC. It needs access to the UTXO set.

    This is copy-paste error leading to incorrect documentation of the test. This test is a 2of2 multisig for which node 2 has only 1 key.

    although at least the documentation in the RPC test should probably be corrected

    Nits addressed and rebased.
  24. morcos commented at 7:08 pm on July 17, 2017: member
    @achow101 It’s better if you address the nits separately from rebasing (was rebasing needed?) otherwise its hard to review just the differential and reACK.

    This comment is still incorrect. The funds should not be spendable there is nothing incomplete here.

    @morcos sorry, I rebased out of habit.
  27. achow101 commented at 7:16 pm on July 17, 2017: member
    Now the comment should be right.
  28. morcos commented at 7:31 pm on July 17, 2017: member

    heh thanks… and i think its ok to squash, especially if the old commit can still be found, b/c then a diff btwn old and new can show the differences. it’s the rebase that makes it difficult

    This won’t work, you’re adding a string and an integer. Use strprintf?
