1. enable diskless replication by default 2. add a new config named repl-diskless-sync-max-replicas that enables replication to start before the full repl-diskless-sync-delay was reached. 3. put replica online sooner on the master (see below) 4. test suite uses repl-diskless-sync-delay of 0 to be faster 5. a few tests that use multiple replica on a pre-populated master, are now using the new repl-diskless-sync-max-replicas 6. fix possible timing issues in a few cluster tests (see below) put replica online sooner on the master ---------------------------------------------------- there were two tests that failed because they needed for the master to realize that the replica is online, but the test code was actually only waiting for the replica to realize it's online, and in diskless it could have been before the master realized it. changes include two things: 1. the tests wait on the right thing 2. issues in the master, putting the replica online in two steps. the master used to put the replica as online in 2 steps. the first step was to mark it as online, and the second step was to enable the write event (only after getting ACK), but in fact the first step didn't contains some of the tasks to put it online (like updating good slave count, and sending the module event). this meant that if a test was waiting to see that the replica is online form the point of view of the master, and then confirm that the module got an event, or that the master has enough good replicas, it could fail due to timing issues. so now the full effect of putting the replica online, happens at once, and only the part about enabling the writes is delayed till the ACK. fix cluster tests -------------------- I added some code to wait for the replica to sync and avoid race conditions. later realized the sentinel and cluster tests where using the original 5 seconds delay, so changed it to 0. this means the other changes are probably not needed, but i suppose they're still better (avoid race conditions) |

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
