wip: fix sig_der test

[bloomingpeach]

• related to [bug] Remaining bitcoin-core test fixes #247
• follows contribution guide
• code change includes tests

currently I am aiming on fixing related issue to SIG_DER error, first thing I've done is update the existing scripts accordingly.

And also I create a new helper script for only run the SIG_DER tests : tests/run-sig-der-tests.sh, and the tests is on tests/sig_der_failing_tests.json

@bloomingpeach is attempting to deploy a commit to the keep-starknet-strange Team on Vercel.

A member of the Team first needs to authorize it.

Hey, thanks. Seems there are a lot of SIG_DER tests this could potentially fix. I can take a deeper look soon, but I noticed a couple tests that were passing before are now giving SIG_DER error results.

Might be worth looking into.

@b-j-roberts I am just confused the flag a little bit, do you think this is correct let strict_encoding = vm.has_flag(ScriptFlags::ScriptVerifyStrictEncoding) || vm.has_flag(ScriptFlags::ScriptVerifyDERSignatures);(in parse_base_sig_and_pk)

[bloomingpeach]

Also do you have an idea to prevent such regression in the future? @b-j-roberts, maybe a nice thing to have when working on fixing these remaining tests.

Hmm, not certain. One way could be to keep track of the passing tests with another run-passing-tests.sh script. It'll be super slow to run though.
Could probably speed it up quite a bit by executing tests in parallel, but might be a little tricky to get right.

Thank you for fixing these tests! I think this is good for now based on the signature parsing we have implemented.
