      Run active defrag while blocked / loading (#7726) · 9ef8d2f6
      Oran Agra authored
      During long running scripts or loading RDB/AOF, we may need to do some
      defragging. Since processEventsWhileBlocked is called periodically at
      unknown intervals, and many cron jobs either depend on run_with_period
      (including active defrag), or rely on being called at server.hz rate
      (i.e. active defrag knows ho much time to run by looking at server.hz),
      the whileBlockedCron may have to run a loop triggering the cron jobs in it
      (currently only active defrag) several times.
      
      Other changes:
      - Adding a test for defrag during aof loading.
      - Changing key-load-delay config to take negative values for fractions
        of a microsecond sleep

      Implement SMISMEMBER key member [member ...] (#7615) · 6f11acbd
      Tyson Andre authored
      
      
      This is a rebased version of #3078 originally by shaharmor
      with the following patches by TysonAndre made after rebasing
      to work with the updated C API:
      
      1. Add 2 more unit tests
         (wrong argument count error message, integer over 64 bits)
      2. Use addReplyArrayLen instead of addReplyMultiBulkLen.
      3. Undo changes to src/help.h - for the ZMSCORE PR,
         I heard those should instead be automatically
         generated from the redis-doc repo if it gets updated
      
      Motivations:
      
      - Example use case: Client code to efficiently check if each element of a set
        of 1000 items is a member of a set of 10 million items.
        (Similar to reasons for working on #7593)
      - HMGET and ZMSCORE already exist. This may lead to developers deciding
        to implement functionality that's best suited to a regular set with a
        data type of sorted set or hash map instead, for the multi-get support.
      
      Currently, multi commands or lua scripting to call sismember multiple times
      would almost definitely be less efficient than a native smismember
      for the following reasons:
      
      - Need to fetch the set from the string every time
        instead of reusing the C pointer.
      - Using pipelining or multi-commands would result in more bytes sent
        and received by the client for the repeated SISMEMBER KEY sections.
      - Need to specially encode the data and decode it from the client
        for lua-based solutions.
      - Proposed solutions using Lua or SADD/SDIFF could trigger writes to
        memory, which is undesirable on a redis replica server
        or when commands get replicated to replicas.

      Add a ZMSCORE command returning an array of scores. (#7593) · f11f26cc
      Tyson Andre authored
      
      
      Syntax: `ZMSCORE KEY MEMBER [MEMBER ...]`
      
      This is an extension of #2359
      amended by Tyson Andre to work with the changed unstable API,
      add more tests, and consistently return an array.
      
      - It seemed as if it would be more likely to get reviewed
        after updating the implementation.
      
      Currently, multi commands or lua scripting to call zscore multiple times
      would almost definitely be less efficient than a native ZMSCORE
      for the following reasons:
      
      - Need to fetch the set from the string every time instead of reusing the C
        pointer.
      - Using pipelining or multi-commands would result in more bytes sent by
        the client for the repeated `ZMSCORE KEY` sections.
      - Need to specially encode the data and decode it from the client
        for lua-based solutions.
      - The fastest solution I've seen for large sets(thousands or millions)
        involves lua and a variadic ZADD, then a ZINTERSECT, then a ZRANGE 0 -1,
        then UNLINK of a temporary set (or lua). This is still inefficient.

      Fix failing tests due to issues with wait_for_log_message (#7572) · 109b5ccd
      Oran Agra authored
      - the test now waits for specific set of log messages rather than wait for
        timeout looking for just one message.
      - we don't wanna sample the current length of the log after an action, due
        to a race, we need to start the search from the line number of the last
        message we where waiting for.
      - when attempting to trigger a full sync, use multi-exec to avoid a race
        where the replica manages to re-connect before we completed the set of
        actions that should force a full sync.
      - fix verify_log_message which was broken and unused

      testsuite may leave servers alive on error (#7549) · 36b94943
      Oran Agra authored
      in cases where you have
      test name {
        start_server {
          start_server {
            assert
          }
        }
      }
      
      the exception will be thrown to the test proc, and the servers are
      supposed to be killed on the way out. but it seems there was always a
      bug of not cleaning the server stack, and recently (#7404) we started
      relying on that stack in order to kill them, so with that bug sometimes
      we would have tried to kill the same server twice, and leave one alive.
      
      luckly, in most cases the pattern is:
      start_server {
        test name {
        }
      }

      runtest --stop pause stops before terminating the redis server (#7513) · 02ef355f
      Oran Agra authored
      in the majority of the cases (on this rarely used feature) we want to
      stop and be able to connect to the shard with redis-cli.
      since these are two different processes interracting with the tty we
      need to stop both, and we'll have to hit enter twice, but it's not that
      bad considering it is rarely used.

      stabilize tests that look for log lines (#7367) · 8e76e134
      Oran Agra authored
      tests were sensitive to additional log lines appearing in the log
      causing the search to come empty handed.
      
      instead of just looking for the n last log lines, capture the log lines
      before performing the action, and then search from that offset.

      tests/valgrind: don't use debug restart (#7404) · 69ade873
      Oran Agra authored
      * tests/valgrind: don't use debug restart
      
      DEBUG REATART causes two issues:
      1. it uses execve which replaces the original process and valgrind doesn't
         have a chance to check for errors, so leaks go unreported.
      2. valgrind report invalid calls to close() which we're unable to resolve.
      
      So now the tests use restart_server mechanism in the tests, that terminates
      the old server and starts a new one, new PID, but same stdout, stderr.
      
      since the stderr can contain two or more valgrind report, it is not enough
      to just check for the absence of leaks, we also need to check for some known
      errors, we do both, and fail if we either find an error, or can't find a
      report saying there are no leaks.
      
      other changes:
      - when killing a server that was already terminated we check for leaks too.
      - adding DEBUG LEAK which was used to test it.
      - adding --trace-children to valgrind, although no longer needed.
      - since the stdout contains two or more runs, we need slightly different way
        of checking if the new process is up (explicitly looking for the new PID)
      - move the code that handles --wait-server to happen earlier (before
        watching the startup message in the log), and serve the restarted server too.
      
      * squashme - CR fixes

      tests: find_available_port start search from next port · 1cf33a46
      Oran Agra authored
      i.e. don't start the search from scratch hitting the used ones again.
      this will also reduce the likelihood of collisions (if there are any
      left) by increasing the time until we re-use a port we did use in the
      past.

      tests: each test client work on a distinct port range · e258a1c0
      Oran Agra authored
      apparently when running tests in parallel (the default of --clients 16),
      there's a chance for two tests to use the same port.
      specifically, one test might shutdown a master and still have the
      replica up, and then another test will re-use the port number of master
      for another master, and then that replica will connect to the master of
      the other test.
      
      this can cause a master to count too many full syncs and fail a test if
      we run the tests with --single integration/psync2 --loop --stop
      
      see Probmem 2 in #7314

      test infra: improve prints on failed assertions · a0cfd519
      Oran Agra authored
      sometimes we have several assertions with the same condition in the same test
      at different stages, and when these fail (the ones that print the condition
      text) you don't know which one it was. other assertions didn't print the
      condition text (variable names), just the expected and unexpected values.
      
      So now, all assertions print context line, and conditin text.
      
      besides, one of the major differences between 'assert' and 'assert_equal',
      is that the later is able to print the value that doesn't match the expected.
      if there is a rare non-reproducible failure, it is helpful to know what was
      the value the test encountered and how far it was from the threshold.
      
      So now, adding assert_lessthan and assert_range that can be used in some places.
      were we used just 'assert { a > b }' so far.

      prevent diskless replica from terminating on short read · c56b4ddc
      Oran Agra authored
      now that replica can read rdb directly from the socket, it should avoid exiting
      on short read and instead try to re-sync.
      
      this commit tries to have minimal effects on non-diskless rdb reading.
      and includes a test that tries to trigger this scenario on various read cases.

      diskless replication on slave side (don't store rdb to file), plus some other related fixes · 2de544cf
      Oran Agra authored
      The implementation of the diskless replication was currently diskless only on the master side.
      The slave side was still storing the received rdb file to the disk before loading it back in and parsing it.
      
      This commit adds two modes to load rdb directly from socket:
      1) when-empty
      2) using "swapdb"
      the third mode of using diskless slave by flushdb is risky and currently not included.
      
      other changes:
      --------------
      distinguish between aof configuration and state so that we can re-enable aof only when sync eventually
      succeeds (and not when exiting from readSyncBulkPayload after a failed attempt)
      also a CONFIG GET and INFO during rdb loading would have lied
      
      When loading rdb from the network, don't kill the server on short read (that can be a network error)
      
      Fix rdb check when performed on preamble AOF
      
      tests:
      run replication tests for diskless slave too
      make replication test a bit more aggressive
      Add test for diskless load swapdb
