Fix timing issue in PSETEX/PEXPIRE sub-second expire tests (#10121) 
These two tests have a high probability of failure
on MacOS. Or it takes many retries to succeed.
Keys often expire before we can access them.

So this time we try to avoid this by reducing the time
of the first `after`, or removeing the first `after`.

The results of doing `20/81` and `0/101` are:
- PEXPIRE (20/81): 1069/1949
- PEXPIREAT (20/81): 1093/1949

- PEXPIRE (0/101): 31936 / 31936
- PEXPIREAT (0/101): 31936 / 31936

The first number is the number of times that the
test succeeded without any retries.
The second number is the total number of executions.

And we can see that `0/101` doesn't even need an extra
retries. Also reduces the time required for testing.
So in the end we chose `0/100`, i.e. remove the first `after`.

As for `PEXPIREAT`, there is no failure, but we still changed
it together, using `0/201`, after 2W tests, none of them failed.

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 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
