      Modules: add RM_GetCommandKeys(). · 116a2042
      Yossi Gottlieb authored
      This is essentially the same as calling COMMAND GETKEYS but provides a
      more efficient interface that can be used in every context (i.e. not a
      Redis command).

      memory reporting of clients argv (#7874) · 76f3a63d
      Oran Agra authored
      track and report memory used by clients argv.
      this is very usaful in case clients started sending a command and didn't
      complete it. in which case the first args of the command are already
      trimmed from the query buffer.
      
      in an effort to avoid cache misses and overheads while keeping track of
      these, i avoid calling sdsZmallocSize and instead use the sdslen /
      bulk-len which can at least give some insight into the problem.
      
      This memory is now added to the total clients memory usage, as well as
      the client list.

      Fixed Tracking test “The other connection is able to get invalidations” (#7871) · a7b95b7c
      nitaicaro authored
      
      
      PROBLEM:
      
      [$rd1 read] reads invalidation messages one by one, so it's never going to see the second invalidation message produced after INCR b, whether or not it exists. Adding another read will block incase no invalidation message is produced.
      
      FIX:
      
      We switch the order of "INCR a" and "INCR b" - now "INCR b" comes first. We still only read the first invalidation message produces. If an invalidation message is wrongly produces for b - then it will be produced before that of a, since "INCR b" comes before "INCR a".

      Don't write replies if close the client ASAP (#7202) · 757ad7cd
      Wang Yuan authored
      
      
      Before this commit, we would have continued to add replies to the reply buffer even if client
      output buffer limit is reached, so the used memory would keep increasing over the configured limit.
      What's more, we shouldn’t write any reply to the client if it is set 'CLIENT_CLOSE_ASAP' flag
      because that doesn't conform to its definition and we will close all clients flagged with
      'CLIENT_CLOSE_ASAP' in ‘beforeSleep’.
      
      Because of code execution order, before this, we may firstly write to part of the replies to
      the socket before disconnecting it, but in fact, we may can’t send the full replies to clients
      since OS socket buffer is limited. But this unexpected behavior makes some commands work well,
      for instance ACL DELUSER, if the client deletes the current user, we need to send reply to client
      and close the connection, but before, we close the client firstly and write the reply to reply
      buffer. secondly, we shouldn't do this despite the fact it works well in most cases.
      
      We add a flag 'CLIENT_CLOSE_AFTER_COMMAND' to mark clients, this flag means we will close the
      client after executing commands and send all entire replies, so that we can write replies to
      reply buffer during executing commands, send replies to clients, and close them later.
      
      We also fix some implicit problems. If client output buffer limit is enforced in 'multi/exec',
      all commands will be executed completely in redis and clients will not read any reply instead of
      partial replies. Even more, if the client executes 'ACL deluser' the using user in 'multi/exec',
      it will not read the replies after 'ACL deluser' just like before executing 'client kill' itself
      in 'multi/exec'.
      
      We added some tests for output buffer limit breach during multi-exec and using a pipeline of
      many small commands rather than one with big response.

      Remove tmp rdb file in background thread (#7762) · 0bdddd3c
      Wang Yuan authored
      We're already using bg_unlink in several places to delete the rdb file in the background,
      and avoid paying the cost of the deletion from our main thread.
      This commit uses bg_unlink to remove the temporary rdb file in the background too.
      
      However, in case we delete that rdb file just before exiting, we don't actually wait for the
      background thread or the main thread to delete it, and just let the OS clean up after us.
      i.e. we open the file, unlink it and exit with the fd still open.
      
      Furthermore, rdbRemoveTempFile can be called from a thread and was using snprintf which is
      not async-signal-safe, we now use ll2string instead.

      fix broken PEXPIREAT test (#7791) · 5106a144
      Oran Agra authored
      This test was nearly always failing on MacOS github actions.
      This is because of bugs in the test that caused it to nearly always run
      all 3 attempts and just look at the last one as the pass/fail creteria.
      
      i.e. the test was nearly always running all 3 attempts and still sometimes
      succeed. this is because the break condition was different than the test
      completion condition.
      
      The reason the test succeeded is because the break condition tested the
      results of all 3 tests (PSETEX/PEXPIRE/PEXPIREAT), but the success check
      at the end was only testing the result of PSETEX.
      
      The reason the PEXPIREAT test nearly always failed is because it was
      getting the current time wrong: getting the current second and loosing
      the sub-section time, so the only chance for it to succeed is if it run
      right when a certain second started.
      
      Because i now get the time from redis, adding another round trip, i
      added another 100ms to the PEXPIRE test to make it less fragile, and
      also added many more attempts.
      
      Adding many more attempts before failure to account for slow platforms,
      github actions and valgrind

      fix recently added time sensitive tests failing with valgrind (#7512) · aea4db2f
      Oran Agra authored
      interestingly the latency monitor test fails because valgrind is slow
      enough so that the time inside PEXPIREAT command from the moment of
      the first mstime() call to get the basetime until checkAlreadyExpired
      calls mstime() again is more than 1ms, and that test was too sensitive.
      
      using this opportunity to speed up the test (unrelated to the failure)
      the fix is just the longer time passed to PEXPIRE.

      RESTORE ABSTTL won't store expired keys into the db (#7472) · 95ba01b5
      Oran Agra authored
      Similarly to EXPIREAT with TTL in the past, which implicitly deletes the
      key and return success, RESTORE should not store key that are already
      expired into the db.
      When used together with REPLACE it should emit a DEL to keyspace
      notification and replication stream.

      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

      EXEC always fails with EXECABORT and multi-state is cleared · 05e483cb
      Oran Agra authored
      In order to support the use of multi-exec in pipeline, it is important that
      MULTI and EXEC are never rejected and it is easy for the client to know if the
      connection is still in multi state.
      
      It was easy to make sure MULTI and DISCARD never fail (done by previous
      commits) since these only change the client state and don't do any actual
      change in the server, but EXEC is a different story.
      
      Since in the past, it was possible for clients to handle some EXEC errors and
      retry the EXEC, we now can't affort to return any error on EXEC other than
      EXECABORT, which now carries with it the real reason for the abort too.
      
      Other fixes in this commit:
      - Some checks that where performed at the time of queuing need to be re-
        validated when EXEC runs, for instance if the transaction contains writes
        commands, it needs to be aborted. there was one check that was already done
        in execCommand (-READONLY), but other checks where missing: -OOM, -MISCONF,
        -NOREPLICAS, -MASTERDOWN
      - When a command is rejected by processCommand it was rejected with addReply,
        which was not recognized as an error in case the bad command came from the
        master. this will enable to count or MONITOR these errors in the future.
      - make it easier for tests to create additional (non deferred) clients.
      - add tests for the fixes of this commit.

      Fix RM_ScanKey module api not to return int encoded strings · 51e17845
      meir@redislabs.com authored
      The scan key module API provides the scan callback with the current
      field name and value (if it exists). Those arguments are RedisModuleString*
      which means it supposes to point to robj which is encoded as a string.
      Using createStringObjectFromLongLong function might return robj that
      points to an integer and so break a module that tries for example to
      use RedisModule_StringPtrLen on the given field/value.
      
      The PR introduces a fix that uses the createObject function and sdsfromlonglong function.
      Using those function promise that the field and value pass to the to the
      scan callback will be Strings.
      
      The PR also changes the Scan test module to use RedisModule_StringPtrLen
      to catch the issue. without this, the issue is hidden because
      RedisModule_ReplyWithString knows to handle integer encoding of the
      given robj (RedisModuleString).
      
      The PR also introduces a new test to verify the issue is solved.
