Subject: [PATCH] Remove http sampler to decrease size and dependencies
|
|
|
|
http sampler increases size of the rezolus binary from 2.5 MiB to 4.1 MiB
|
|
(opt-level="z", panic="abort", lto, stripped) and adds dependency on libssl
|
|
and libcrypto.
|
|
|
|
I think that it's a bit out of scope of the Rezolus purpose and there are
|
|
better tools for this. If there will be demand for this sampler, we can
|
|
build and provide two variants of rezolus (e.g. rezolus and rezolus-http).
