After https://github.com/redis/redis/pull/13816, we make a new API to defrag RedisModuleDict. Currently, we only support incremental defragmentation of the dictionary itself, but the defragmentation of values is still not incremental. If the values are very large, it could lead to significant blocking. Therefore, in this PR, we have added incremental defragmentation for the values. The main change is to the `RedisModuleDefragDictValueCallback`, we modified the return value of this callback. When the callback returns 1, we will save the `seekTo` as the key of the current unfinished node, and the next time we enter, we will continue defragmenting this node. When the return value is 0, we will proceed to the next node. ## Test Since each dictionary in the global dict originally contained only 10 strings, but now it has been changed to a nested dictionary, each dictionary now has 10 sub-dictionaries, with each sub-dictionary containing 10 strings, this has led to a corresponding reduction in the defragmentation time obtained from other tests. Therefore, the other tests have been modified to always wait for defragmentation to be turned off before the test begins, then start it after creating fragmentation, ensuring that they can always run for a full defragmentation cycle. --------- Co-authored-by: ephraimfeldblum <ephraim.feldblum@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. |
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
