Bugfix: RPC/Wallet: Include HD key metadata in dumpwallet #11803

luke-jr · 2017-11-30T20:32:01Z

When restoring a backup, we should restore the wallet metadata. This moves some of it out of "comment" sections so that it can be sensibly handled by parsing tools.

(importwallet doesn't currently support it, but that's another matter to address)

promag

Update test? Squash 2nd and 3rd commits?

                file << "inactivehdmaster=1";
            } else {
                file << "change=1";
            }
-            file << strprintf(" # addr=%s%s\n", strAddr, (pwallet->mapKeyMetadata[keyid].hdKeypath.size() > 0 ? " hdkeypath="+pwallet->mapKeyMetadata[keyid].hdKeypath : ""));
+            file << strprintf(" # addr=%s%s\n", strAddr, (meta.hdKeypath.empty() ? "" : (" hdkeypath=" + meta.hdKeypath)));


Nit, partial unrelated change to what commit stands for.

@luke-jr: can you please elaborate a little bit what situation this PR does improve?

laanwj · 2018-01-30T09:47:30Z

@luke-jr Can you please answer @jonasschnelli 's question? There is no rationale in the OP at all.

Tested ACK 17d609c

This isn't really a bugfix because there is no bug in the codebase which is fixed right? But I agree its a sensible change.

Supporting it with importwallet is definitely something that needs to be done, ideally that should be done at the same time because they're mirror functions. But this doesn't break compatibility with the current importwallet so it should be ok to leave it for a future PR.

luke-jr · 2018-11-10T19:59:37Z

I think it's a bugfix because without it (and another fix to importwallet), dump/import will produce a wallet missing the key metadata. Isn't the goal of these RPCs to produce the same wallet?

Sjors · 2018-11-20T18:36:54Z

Concept ACK and lightly tested 17d609c.

Unrelated, I don't like that the address column depends on the currently active address type. We could replace it with an inferred combo() descriptor after #14477.

The following sections might be updated with supplementary metadata relevant to reviewers and maintainers.

Conflicts

Reviewers, this pull request conflicts with the following ones:

#23127 (tests: Use test framework utils where possible by vincenzopalazzo)
#22805 (refactor: use CWallet const shared pointers in dump{privkey,wallet} by theStack)

If you consider this pull request important, please also help to review the conflicting pull requests. Ideally, start with the one that should be merged first.

Sjors · 2019-02-15T15:06:09Z

This has been fixed as part of #14021 (not just for importmulti):

It could still be useful to switch over to inferred descriptors, so we also get the origin info.

Sjors · 2019-02-16T08:35:32Z

Just noticed that it's a seperate field now, but sill in the comment section, so we could move it to the left.

src/wallet/rpcdump.cpp

                file << "inactivehdseed=1";
            } else {
                file << "change=1";
            }
-            file << strprintf(" # addr=%s%s\n", strAddr, (pwallet->mapKeyMetadata[keyid].has_key_origin ? " hdkeypath="+WriteHDKeypath(pwallet->mapKeyMetadata[keyid].key_origin.path) : ""));
+            if (meta.has_key_origin) {
+                file << " hdkeypath=" + WriteHDKeypath(meta.key_origin.path);


We should also write out the master fingerprint here too (part of key_origin). I think instead of a separate field for that, we could instead write that in the same way descriptors and psbt do key origin information, i.e. fingerprint instead of m in the path.

Concept ACK

Will try this today. Wallet with metadata is obviously better than wallet missing the key metadata.

This PR will complete 1337 days next week

Compiled and tried in POP!_OS with a new wallet (legacy / testnet). Diff for the dump files: https://ghostbin.com/paste/L2SXs. Observed the below things when comparing dump files for Master and PR branch:

hdseedid added for reserve=1 key type

I think commits should be squashed.
Totally agree with prayank23: Wallet with metadata is obviously better than wallet missing the key metadata

This tests failed on my env though. Is it just me?

This is exactly how I fetched the branch, compiled the binnaries and ran the tests.

git fetch core
git fetch core pull/11803/merge:pr11803
git switch pr11803
./autogen.sh
./configure -q --without-gui

Checked my HEAD commit within my local PR copy and I'm getting 8642fbd which differs from the last commit I see on the commit tab here, am I doing something wrong?

Rspigler · 2021-07-30T05:01:26Z

Tested on master for legacy wallets:

I get an extended private masterkey

Then a list of (private key, address, hdkeypath); although very out of order. Somewhere in there, is the hdseed

Master for descriptor wallets:

This type of wallet does not support this command (code -4)

Tested on 563dda4:

Legacy:

Extended private master key.

Then list of (private key, hdkeypath, hdseedid, address). Changes are address is moved to the end of the list, and addition of hdseedid. The keys are still out of order, and the hdseed is also still randomly in the list.

Descriptor:

Unable to create descriptor wallet (either through the GUI or console), so unable to test.

Possible improvements?:

Work with descriptors
Sort addresses/hdkeypaths by address index
Bring the hdseed to top of list, like the extended private master key is
List the hdseedid once at top of list, instead of repeated for every address?

Rspigler · 2021-08-03T19:03:21Z

Work with descriptors

Maybe I was thinking of listdescriptors
