      Improve test suite to handle external servers better. (#9033) · 8a86bca5
      Yossi Gottlieb authored
      This commit revives the improves the ability to run the test suite against
      external servers, instead of launching and managing `redis-server` processes as
      part of the test fixture.
      
      This capability existed in the past, using the `--host` and `--port` options.
      However, it was quite limited and mostly useful when running a specific tests.
      Attempting to run larger chunks of the test suite experienced many issues:
      
      * Many tests depend on being able to start and control `redis-server` themselves,
      and there's no clear distinction between external server compatible and other
      tests.
      * Cluster mode is not supported (resulting with `CROSSSLOT` errors).
      
      This PR cleans up many things and makes it possible to run the entire test suite
      against an external server. It also provides more fine grained controls to
      handle cases where the external server supports a subset of the Redis commands,
      limited number of databases, cluster mode, etc.
      
      The tests directory now contains a `README.md` file that describes how this
      works.
      
      This commit also includes additional cleanups and fixes:
      
      * Tests can now be tagged.
      * Tag-based selection is now unified across `start_server`, `tags` and `test`.
      * More information is provided about skipped or ignored tests.
      * Repeated patterns in tests have been extracted to common procedures, both at a
        global level and on a per-test file basis.
      * Cleaned up some cases where test setup was based on a previous test executing
        (a major anti-pattern that repeats itself in many places).
      * Cleaned up some cases where test teardown was not part of a test (in the
        future we should have dedicated teardown code that executes even when tests
        fail).
      * Fixed some tests that were flaky running on external servers.

      Fix SLOWLOG for blocked commands (#8632) · 497351ad
      Oran Agra authored
      * SLOWLOG didn't record anything for blocked commands because the client
        was reset and argv was already empty. there was a fix for this issue
        specifically for modules, now it works for all blocked clients.
      * The original command argv (before being re-written) was also reset
        before adding the slowlog on behalf of the blocked command.
      * Latency monitor is now updated regardless of the slowlog flags of the
        command or its execution (their purpose is to hide sensitive info from
        the slowlog, not hide the fact the latency happened).
      * Latency monitor now uses real_cmd rather than c->cmd (which may be
        different if the command got re-written, e.g. GEOADD)
      
      Changes:
      * Unify shared code between slowlog insertion in call() and
        updateStatsOnUnblock(), hopefully prevent future bugs from happening
        due to the later being overlooked.
      * Reset CLIENT_PREVENT_LOGGING in resetClient rather than after command
        processing.
      * Add a test for SLOWLOG and BLPOP
      
      Notes:
      - real_cmd == c->lastcmd, except inside MULTI and Lua.
      - blocked commands never happen in these cases (MULTI / Lua)
      - real_cmd == c->cmd, except for when the command is rewritten (e.g.
        GEOADD)
      - blocked commands (currently) are never rewritten
      - other than the command's CLIENT_PREVENT_LOGGING, and the
        execution flag CLIENT_PREVENT_LOGGING, other cases that we want to
        avoid slowlog are on AOF loading (specifically CMD_CALL_SLOWLOG will
        be off when executed from execCommand that runs from an AOF)

      Test: fix slowlog test false positive. · 1a1ba483
      antirez authored
      In fast systems "SLOWLOG RESET" is fast enough to don't be logged even
      when the time limit is "1" sometimes. Leading to false positives such
      as:
      
      [err]: SLOWLOG - can be disabled in tests/unit/slowlog.tcl
      Expected '1' to be equal to '0'

      Slowlog: don't log EXEC but just the executed commands. · 08d200ba
      antirez authored
      The Redis Slow Log always used to log the slow commands executed inside
      a MULTI/EXEC block. However also EXEC was logged at the end, which is
      perfectly useless.
      
      Now EXEC is no longer logged and a test was added to test this behavior.
      
      This fixes issue #759.

      Limit memory used by big SLOWLOG entries. · d3701d27
      antirez authored
      Two limits are added:
      
      1) Up to SLOWLOG_ENTRY_MAX_ARGV arguments are logged.
      2) Up to SLOWLOG_ENTRY_MAX_STRING bytes per argument are logged.
      3) slowlog-max-len is set to 128 by default (was 1024).
      
      The number of remaining arguments / bytes is logged in the entry
      so that the user can understand better the nature of the logged command.
