Stabilization and improvements around aof tests (#12626)
In some tests, the code manually searches for a log message, and it
uses tail -1 with a delay of 1 second, which can miss the expected line.

Also, because the aof tests use start_server_aof and not start_server,
the test name doesn't log into the server log.

To fix the above, I made the following changes:
- Change the start_server_aof to wrap the start_server.
  This will add the created aof server to the servers list, and make
  srv() and wait_for_log_messages() available for the tests.

- Introduce a new option for start_server.
  'wait_ready' - an option to let the caller start the test code without
  waiting for the server to be ready. useful for tests on a server that
  is expected to exit on startup.

- Create a new start_server_aof_ex.
  The new proc also accept options as argument and make use of the
  new 'short_life' option for tests that are expected to exit on startup
  because of some error in the aof file(s).

Because of the above, I had to change many lines and replace every
local srv variable (a server config) usage with the srv().

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 context
  • tags 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 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
