Support SFLUSH to flush slots partially (#14750)
Currently, the SFLUSH command is permitted only when the specified slot
range fully covers all slot ranges owned by the node. We want to enable
it to perform partial slot flushes instead, and the reply should be list
of ranges that were flushed.

for implementation, we use TRIMSLOTS functionalities (added as part of
ASM work) to support flush async.

**NOTE**: Redis will reply `-TRYAGAIN Slot is being trimmed` error if
clients send write commands to given slots during SFLUSH execution,
clients should not send write commands to these slots before getting
reply of SFLUSH command.

And there is still an issue if we use active trim for `SFLUSH ASYNC`
https://github.com/redis/redis/pull/14750#discussion_r2791904891, so we
still mark this command `experimental`, we may remove this tag when we
deprecate active slot trimming or don't support ASYNC option.

Redis Test Suite

The normal execution mode of the test suite involves starting and manipulating local redis-server instances, inspecting process state, log files, etc.

The test suite also supports execution against an external server, which is enabled using the --host and --port parameters. When executing against an external server, tests tagged external:skip are skipped.

There are additional runtime options that can further adjust the test suite to match different external server configurations:

Option Impact
--singledb Only use database 0, don't assume others are supported.
--ignore-encoding Skip all checks for specific encoding.
--ignore-digest Skip key value digest validations.
--cluster-mode Run in strict Redis Cluster compatibility mode.
--large-memory Enables tests that consume more than 100mb

Tags

Tags are applied to tests to classify them according to the subsystem they test, but also to indicate compatibility with different run modes and required capabilities.

Tags can be applied in different context levels:

  • start_server context
  • tags context that bundles several tests together
  • A single test context.

The following compatibility and capability tags are currently used:

Tag Indicates
external:skip Not compatible with external servers.
cluster:skip Not compatible with --cluster-mode.
large-memory Test that requires more than 100mb
tls:skip Not compatible with --tls.
tsan:skip Not compatible with running under thread sanitizer.
needs:repl Uses replication and needs to be able to SYNC from server.
needs:debug Uses the DEBUG command or other debugging focused commands (like OBJECT REFCOUNT).
needs:pfdebug Uses the PFDEBUG command.
needs:config-maxmemory Uses CONFIG SET to manipulate memory limit, eviction policies, etc.
needs:config-resetstat Uses CONFIG RESETSTAT to reset statistics.
needs:reset Uses RESET to reset client connections.
needs:save Uses SAVE or BGSAVE to create an RDB file.

When using an external server (--host and --port), filtering using the external:skip tags is done automatically.

When using --cluster-mode, filtering using the cluster:skip tag is done automatically.

When not using --large-memory, filtering using the largemem:skip tag is done automatically.

In addition, it is possible to specify additional configuration. For example, to run tests on a server that does not permit SYNC use:

./runtest --host <host> --port <port> --tags -needs:repl
