### Summary This PR introduces two new maxmemory eviction policies: `volatile-lrm` and `allkeys-lrm`. LRM (Least Recently Modified) is similar to LRU but only updates the timestamp on write operations, not read operations. This makes it useful for evicting keys that haven't been modified recently, regardless of how frequently they are read. ### Core Implementation The LRM implementation reuses the existing LRU infrastructure but with a key difference in when timestamps are updated: - **LRU**: Updates timestamp on both read and write operations - **LRM**: Updates timestamp only on write operations via `updateLRM()` ### Key changes: Add `keyModified()` to accept an optional `robj *val` parameter and call `updateLRM()` when a value is provided. Since `keyModified()` serves as the unified entry point for all key modifications, placing the LRM update here ensures timestamps are consistently updated across all write operations --------- Co-authored-by: oranagra <oran@redislabs.com> Co-authored-by: Yuan Wang <yuan.wang@redis.com> |

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_servercontexttagscontext 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
