refactor: Remove ::Params() global from CChainState #21789

maflcko · 2021-04-27T18:51:20Z

The ::Params() global is verbose and confusing. Also it makes tests a bit harder to write because they'd have to mock a global.

Fix all issues by simply using a member variable that points to the right params.

Concept ACK.

It looks like a very nice simplification which makes it harder to make a mistake.

The main change in the first commit (fa216cc) seems to be: "refactor: Add CChainState member to CChainState class" rather than "refactor: Remove ::Params() global from CChainState".

Also, the changes like this fa216cc#diff-97c3a52bc5fad452d82670a7fd291800bae20c7bc35bb82686c2c0a4ea7b5b98R2284 in the first commit (fa216cc) can probably be moved to the second commit (fa06aaa) so that the first commit would only introduce m_params.

Changes in fa216cc & fa06aaa LGTM.

I think the two commits are nicely split up. The first one removes it from inside the functions, the second removes the arg of the functions.

…ctions It is confusing and verbose to repeatedly access the global when a member variable can simply refer to it.

Passing this is confusing and redundant with the m_params member.

Is #include <chainparams.h> still needed?

Thanks, will try to remove if I have to force push

Nice refactoring idea, glad to see this simplification of the CChainState interface.
