This fails on travis. Presumably because gpg is missing, etc

I wonder if 9e03b891af is enough self explanatory
about the bugs it fixes.

It wouldn't hurt me adding a thorough detailed text to it.

Sjors · 2021-11-15T08:57:40Z

@katesalazar that commit ensures that we we add a new version to the list, everything keeps working. It also adds some missing node_master.unloadwallet statements. I wrote it more than a year ago, so that's all I remember :-)

I guess the test failure in feature_backwards_compatibility.py --legacy-wallet is not spurious, because it happened before the rebase too. But I can't reproduce it on macOS. Update: reproduced on Ubuntu...

Sjors · 2021-11-15T10:43:52Z

The test framework sets -sandbox=log-and-abort for version 22.0 and up, but that's not part of the release binary. I added a commit to fix that.

I'll rebase after #23514 is fixed.

Sjors · 2021-11-15T16:24:59Z

Rebased after #23515 and merge conflict.

Code review ACK 62b22de. This all looks very good, and the deduping is nice. Left suggestions below but they aren't important and are just questions and requests to explain some things better.

All of the changes in this commit seem innocuous, but also arbitrary, and I don't know what they are doing. It would be great if the commit description had some summary to help reviewers like me, or to help debug in case any of these changes cause problems in the future.

What I was trying to tell, clearly expressed.

I added a bit more clarification. In particular I point out that coverage may have changed, which I think is worth it for the increased readability.

Does this change belong in this commit? Could it be split off or have a rationale mentioned in a commit description?

Yes, the DMG was added in an earlier PR, but shouldn't have. I'll add a note.

In commit "test: v0.20.1 backwards compatibility" (94d3989)

The deduplication here is great but the nodes[2:] references are more obscure and maybe fragile. Could this use for node in legacy_nodes? And

legacy_nodes = [node_v19, node_v18, node_v17]
or
legacy_nodes = nodes[2:]
or
legacy_nodes = [node for node in nodes if node.version <= 190000]

?

I've now restricted self.nodes[...] to the top of the test, using more human readable names in the rest of the test.

In commit "test: v0.20.1 backwards compatibility" (94d3989)

Looking at all the test changes here it seems like no test coverage is lost, but it would be nice if commit message could say whether this is the case.

IMO, it would also be nicer if this commit were split into a refactoring commit that did not change coverage and just deduped code, and a smaller followup commit adding the new v0.20 version. But just mentioning however this commit affects coverage would be good if you don't want to change the commit contents.

I moved the refactoring stuff into the misc changes commit. Adding a note that perhaps coverage changed in the process of this cleanup.

+            if version > 219999:
+                version *= 100


In commit "test: previous releases: add v22.0" (62b22de)

This seems a little strange. Could you add a code comment here explaining this? It seems like this code could not have a special 219999 case and just multiply by 100 for all versions and strip .0.0 for all versions.

I'll add a note. When we changed the numbering in version v22.0, the client version wasn't bumped to 22000000, but to 220000. Without this change it would expect the binary to live in v0.22.0. Conversely if we multiplied all versions by 100 then it would look for v21.0 for the 0.21.0 release.

Sjors · 2021-11-18T14:41:24Z

Rebased, moved refactoring stuff out of the v0.20 commit into 408e9b4. I improved that commit further by using variables in more places instead of indexes.

Code review ACK 7124899057a351a3491b288d96426f91ef1fd040. This PR looks great and now is simpler to review with code changes consolidated in one commit, and new releases added in other commits. Other than that, only other changes since last review are replacing hardcoded node indexes with variables, and adding a code and commit comments

In commit "test: backwards compatibility: misc fixes" (408e9b48765dee164578c97b6006c525c70a14f4)

Note: Dropping these node_v18.rpc.createwallet and node_v19.rpc.createwallet calls seems to lose test coverage creating these wallets. But the wallets are never used later, and this would only be testing create code in frozen releases, so losing these is probably good.

test/functional/test_framework/test_framework.py

Sjors · 2021-12-01T05:23:04Z

Thanks @ryanofsky. I fixed the indentation and added the requested comment.

It is not possible to run the compatibility tests on i686 because the releases v20+ are missing for that arch. It would be possible to self-compile those releases, but then one can also self-compile 0.15-0.19.

This cleanup may slightly impact test coverage. Reduce code repition by looping over the list of nodes. Reduce brittleness by refering to nodes by name rather than index. Add helper method nodes_wallet_dir.

The file checksums were added in an earlier commit. Since the DMG file is never downloaded, we drop that checksum.

The -sandbox argument is not present in the v22.0 release. Changing the minimum version to 229900 ensures it's used when testing the master branch. If the argument is backported, the minimum version can be adjusted to e.g. 220100.

Sjors · 2021-12-16T05:51:48Z

Rebased and included #19332.

ryanofsky

Code review ACK 24cec4b. Only change since last review is rebasing and adding comment and whitelist args.

I'm surprised this PR is still open. It seems useful and not a particularly risky change to merge.
