      Cluster migration test cleanup. (#8726) · 6a052af8
      Yossi Gottlieb authored
      * Dump more output on error (always, cluster tests currently have no
      verbose flag).
      * Slow down redis-cli check iteration.

      Add support for plaintext clients in TLS cluster (#8587) · 5629dbe7
      Viktor Söderqvist authored
      The cluster bus is established over TLS or non-TLS depending on the configuration tls-cluster. The client ports distributed in the cluster and sent to clients are assumed to be TLS or non-TLS also depending on tls-cluster.
      
      The cluster bus is now extended to also contain the non-TLS port of clients in a TLS cluster, when available. The non-TLS port of a cluster node, when available, is sent to clients connected without TLS in responses to CLUSTER SLOTS, CLUSTER NODES, CLUSTER SLAVES and MOVED and ASK redirects, instead of the TLS port.
      
      The user was able to override the client port by defining cluster-announce-port. Now cluster-announce-tls-port is added, so the user can define an alternative announce port for both TLS and non-TLS clients.
      
      Fixes #8134

      re-fix config rewrite for empty save directive (#8722) · 28375ff6
      JunhuaY authored
      the bug was also discussed in #8716, and was solved in #8719, but incompletely:
      when the server is started, and the save option is default, if you issue the " config set save "" "
      to change the save option, and then issue the “config rewrite” command, the " save "" " won't be saved.

      solve race conditions in psync2-pingoff test (#8720) · cd81dcf1
      Oran Agra authored
      Another test race condition in the macos tests.
      the test was waiting for PINGs to be generated and put on the replication stream,
      but waiting for 1 or 2 seconds doesn't really guarantee that.
      then the test that expected 6 full syncs, found only 4

      make processCommand check publish channel permissions. (#8534) · e138698e
      Huang Zhw authored
      Add publish channel permissions check in processCommand.
      
      processCommand didn't check publish channel permissions, so we can
      queue a publish command in a transaction. But when exec the transaction,
      it will fail with -NOPERM.
      
      We also union keys/commands/channels permissions check togegher in
      ACLCheckAllPerm. Remove pubsubCheckACLPermissionsOrReply in 
      publishCommand/subscribeCommand/psubscribeCommand. Always 
      check permissions in processCommand/execCommand/
      luaRedisGenericCommand.

      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)

      Fix script kill to work also on scripts that use pcall (#8661) · 9ae4f5c7
      Meir Shpilraien (Spielrein) authored
      pcall function runs another LUA function in protected mode, this means
      that any error will be caught by this function and will not stop the LUA
      execution. The script kill mechanism uses error to stop the running script.
      Scripts that uses pcall can catch the error raise by the script kill mechanism,
      this will cause a script like this to be unkillable:
      
      local f = function()
              while 1 do
                      redis.call('ping')
              end
      end
      while 1 do
              pcall(f)
      end
      
      The fix is, when we want to kill the script, we set the hook function to be invoked 
      after each line. This will promise that the execution will get another
      error before it is able to enter the pcall function again.

      Fixes for systems with 64-bit time (#8662) · 169be042
      Theo Buehler authored
      Some operating systems (e.g., NetBSD and OpenBSD) have switched to
      using a 64-bit integer for time_t on all platforms. This results in currently
      harmless compiler warnings due to potential truncation.
      These changes fix these minor portability concerns.
      
      * Fix format string for systems with 64 bit time
      * use llabs to avoid truncation with 64 bit time

      Cleanup: remove dead code from anet. (#8660) · f657315e
      Yossi Gottlieb authored
      In the long term we may want to move away from anet completely and have
      everything implemented natively in connection.c, instead of having an
      extra layer.
      
      For now, just get rid of unused code.

      When tests exit normally, some processes may still be alive (#8647) · a19c4058
      Huang Zhw authored
      In certain scenario start_server may think it failed to start a redis server
      although it started successfully. in these cases, it'll not terminate it, and
      it'll remain running when the test is over.
      
      In start_server if config doesn't have bind (the minimal.conf in introspection.tcl),
      it will try to bind ipv4 and ipv6. One may success while other fails. It will
      output "Could not create server TCP listening socket".
      wait_server_started uses this message to check whether instance started
      successfully. So it will consider that it failed even though redis started successfully.
      
      Additionally, in some cases it wasn't clear to users why the server exited,
      since the warning message printed to the log, could in some cases be harmless,
      and in some cases fatal.
      
      This PR adds makes a clear distinction between a warning log message and
      a fatal one, and changes the test suite to look for the fatal message.
