Script unit is a new unit located on script.c. Its purpose is to provides an API for functions (and eval) to interact with Redis. Interaction includes mostly executing commands, but also functionalities like calling Redis back on long scripts or check if the script was killed. The interaction is done using a scriptRunCtx object that need to be created by the user and initialized using scriptPrepareForRun. Detailed list of functionalities expose by the unit: 1. Calling commands (including all the validation checks such as acl, cluster, read only run, ...) 2. Set Resp 3. Set Replication method (AOF/REPLICATION/NONE) 4. Call Redis back to on long running scripts to allow Redis reply to clients and perform script kill The commit introduce the new unit and uses it on eval commands to interact with Redis.
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
contexttags
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 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
