@veox I didn't look into this yet but I rebased this and it doesn't show the 74 failures that you mentioned we should expect. Just wanted to ping you in case you wanted to look into that (otherwise, I'll do that soon). Also, I assume the linked tests aren't yet up to date in regard to EIP1234 and EIP1283 because otherwise they should definitely fail as we don't have these yet (with EIP1234 basically being ready in #1303) |
@cburgdorf I meant they'd show if you rebased against master (to incorporate the few fixes) and bumped It would then show 74 failures, instead of the 77 it was showing previously. That is, if there weren't new tests added upstream (I think there were) that would fail on |
@veox Ah gotcha! Thanks for clarifying! |

Yes, I think so. I'll try to move this forward today. Btw, is it correct to assume that we can not activate the constantinople rpc test before the Constantinople VM actually landed in the mainnet config with a block number. Because, these tests are based on the

Should a check for collisions be made first?..
EDIT: E.g., same as on line 010b840#diff-8b72e7215cd1bf65062b0a7071e3ded0R175
EDIT2: Seems like no; at least a naiive copy-paste didn't help here.
@veox We skipped two This is not a problem for Constantinople because it cannot happen on mainnet, but for the long-term future, we probably still want to find some resolutions. |
I'm good with skipping the tests mentioned by @sorpaas (but lets be sure to add a beefy comment explaining why and linking at minimum to this thread). |

2 COMMITS SQUASHED: fixtures: include missing Constantinople in helpers. Debugging CREATE2 using the full "Blockchain" tests in `fixtures` (they are disabled in `py-evm`, because they're slow and a duplication of "State" tests). A few definitions are missing - so add them. tests/conftest: fix VM-tracing log-to-file helper. Also move `import`s out of the helper, so they're not encountered by the interpreter on every invocation of the helper.
One is existing `RevertInCreateInInit`, but now for Constantinople, not just Byzantium. The other is `RevertInCreateInInitCreate2`, which contains the same "synthhetic" state which can't be arrived at by regular means in the EVM. It's likely a copy-paste atavism.
Enable tests that are _still_ disabled
Instead of emitting expected - actual, emit actual - expected. Rationale (by @veox): > For example, as things stand, if a fixture-expected value is 1000, and > the actual produced by py-evm is 500, the printed message will show a > delta of 500 - that is, a net positive, whereas what truly happened is > py-evm having produced a value that's too low. This is confusing: say, a > miner's account balance showing "Delta: 500" makes one think that the > miner received 500 wei more than expected (which is not true).

What was wrong?
We need to run the global state tests from
ethereum/test
for the upcoming constantinople forkHow was it fixed?
fixtures
against ethereum/tests@10ab37c which is a WIP branch containing some of the new constantinople tests. We'll most likely have to update this to a different version prior to mergetest_state.py
to handle Constantinople testsWe need to keep this PR open and continue to rebase it until we get all tests passing. Also notice that there are some tests failing for other forks as well which either means, we have some evm bugs or just need to adjust the test setup somehow.
