After fcb8d040 ("treewide: use Software Package Data Exchange
(SPDX) license identifiers"), many dual-licensed files were
left with empty comments on top. Remove them to avoid visual
noise.
Closes#10562
Instead of lengthy blurbs, switch to single-line, machine-readable
standardized (https://spdx.dev) license identifiers. The Linux kernel
switched long ago, so there is strong precedent.
Three cases are handled: AGPL-only, Apache-only, and dual licensed.
For the latter case, I chose (AGPL-3.0-or-later and Apache-2.0),
reasoning that our changes are extensive enough to apply our license.
The changes we applied mechanically with a script, except to
licenses/README.md.
Closes#9937
There are now 231 translation units that indirectly include commitlog.hh
due to the need to have access to db::commitlog::force_sync.
Move that type to a new file commitlog_types.hh and make it available
without access to the commitlog class.
This reduces the number of translation units that depend on commitlog.hh
to 84, improving compile time.
Use per CF-id reference count instead, and use handles as result of
add operations. These must either be explicitly released or stored
(rp_set), or they will release the corresponding replay_position
upon destruction.
Note: this does _not_ remove the replay positioning ordering requirement
for mutations. It just removes it as a means to track segment liveness.
Refs #1813 (fixes scylla part)
Added require_client_auth and priority_string options to
server_encryption_options/client_encryption_options an process them.
Allows TLS method/algo specification. Also enabled enforcing known cert
authentication for both node-to-node and client communication.
