commit 9067cf6ccdce0a73922f06937e54c2fce2752038
Author: Richard Levitte <levitte at openssl.org>
Date: Mon Jun 14 09:25:53 2021 +0200
CORE: Move away the allocation of the temporary no_cache method store
The responsibility for managing the temporary store for methods from
algorithm implementations flaged "no_store" is moved up to the diverse
method fetching functions. This allows them to allocate it "just in
time", or in other words not at all if there is not such algorithm
implementation.
This makes this temporary store more flexible if it's needed outside
of the core fetching functionality, and slightly faster when this
temporary store isn't necessary at all.
