10:54 < ghost43> could someone have a look at this? https://gist.github.com/SomberNight/8d7b065e74449a8716da9a98cac3cae2
10:54 < ghost43> getdescriptorinfo and importmulti disagree on what the "correct" checksum is
10:57 < ghost43> maybe because of tpub/regtest combo?
11:05 < gwillen> ghost43: I think the problem might be with your use of single quotes?
11:05 < gwillen> you have the single quotes of the descriptor inside the single quotes you're using to quote it
11:05 < gwillen> which are getting mangled by the shell
11:05 < ghost43> gwillen: no, it works if I change the checksum to what it is suggesting
11:06 < gwillen> yes but I think that's because it's the correct checksum for the wrong descriptor
11:06 < gwillen> because the shell is removing your internal single quotes, effectively
11:06 < gwillen> so it's turning all your derivations into public by accident
11:07 < gwillen> if you had an odd number of them it would fail, but by luck you have an even number so the shell thinks they are matching quotation marks
11:07 < gwillen> try putting "echo" in front of "bitcoin-cli" and see what gets echoed
11:07 < gwillen> I bet you will see your descriptor get mangled
11:08 < gwillen> I filed this issue awhile ago to switch the default from ' to h, but I let it fall by the wayside... https://github.com/bitcoin/bitcoin/issues/15740
11:17 < ghost43> gwillen: right, yes, that was the main issue.  there is still another thing - I guess I don't understand getdescriptorinfo... why is are there two different checksums in the return value?
11:17 < ghost43> the hex after the "#", and the value for the "checksum" key are different
11:18 < ghost43> and importmulti wants the value for the checksum key, so I can't just copy-paste the "descriptor" returned by getdescriptorinfo.  very confusing
11:20 < gwillen> yeah, that's a little confusing
11:20 < gwillen> the "checksum" field is the checksum for the descriptor you provided
11:21 < gwillen> the returned descriptor may be different from the descriptor you provided, because it's parsed in and then printed out again from the parsed form, so e.g. all the "h" changed to "'"
11:21 < gwillen> which means it has a different checksum
11:21 < gwillen> so the "checksum" field corresponds to the descriptor you originally passed in, and you can append it to that with "#" and it should work
11:22 < gwillen> with the shell quoting issue fixed, importmulti should accept either version
11:25 < ghost43> ah I see. thanks

11:39 < gwillen> np, glad I could help!
11:51 < achow101> apparently the dependencies bump broke some stuff. So I'm going to branch 1.x at the merge commit before that
11:52 < achow101> fixing the broken stuff requires updating the vendor libs and updating trezorlib is far more involved than it probably should be
