This is needed in order to ease the deployment of functions for ephemeral cases, where user needs to spin up a server with functions pre-loaded. #### Details: * Added `--functions-rdb` option to _redis-cli_. * Functions only rdb via `REPLCONF rdb-filter-only functions`. This is a placeholder for a space separated inclusion filter for the RDB. In the future can be `REPLCONF rdb-filter-only "functions db:3 key-patten:user*"` and a complementing `rdb-filter-exclude` `REPLCONF` can also be added. * Handle "slave requirements" specification to RDB saving code so we can use the same RDB when different slaves express the same requirements (like functions-only) and not share the RDB when their requirements differ. This is currently just a flags `int`, but can be extended to a more complex structure with various filter fields. * make sure to support filters only in diskless replication mode (not to override the persistence file), we do that by forcing diskless (even if disabled by config) other changes: * some refactoring in rdb.c (extract portion of a big function to a sub-function) * rdb_key_save_delay used in AOFRW too * sendChildInfo takes the number of updated keys (incremental, rather than absolute) Co-authored-by: Oran Agra <oran@redislabs.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 campatible 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). |
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 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
