Remove unused scratch space from API #1305

jonasnick · 2023-05-11T14:05:12Z

Not sure if we want the typedef and secp256k1_scratch_space_{create,destroy} but if we don't keep them then this PR will be a rather large diff.

I should have mentioned the rationale. The idea is to remove the scratch space from the API is because it's unused right now. Maybe we bring it back (in some form) at some point (see #1302).

See my rationale in #1302 (comment)

8be3839 Remove unused scratch space from API (Jonas Nick) Pull request description: We had already merged this in #1305, but it was reverted before a release (#1311) because this change is not backwards compatible but at the time we only wanted to make a patch release in order to fix an actual issue. Due to the musig module, the next release will increment the version number from 0.5.x to 0.6.0, so it would be a good time to remove the scratch space from the API.
