      Fix issue where fork process deletes the parent pidfile (#8231) · 92a483bc
      Meir Shpilraien (Spielrein) authored
      Turns out that when the fork child crashes, the crash log was deleting
      the pidfile from the disk (although the parent is still running.
      
      Now we set the pidfile of the fork process to NULL so the fork process
      will never deletes it.

      Fix crashes with io-threads-do-reads enabled. (#8230) · e7047ec2
      Yossi Gottlieb authored
      Normally IO threads should simply read data from the socket into the
      buffer and attempt to parse it.
      
      If a protocol error is detected, a reply is generated which may result
      with installing a write handler which is not thread safe. This fix
      delays that until the client is processed back in the main thread.
      
      Fixes #8220

      Remove read-only flag from non-keyspace cmds, different approach for EXEC to... · 411c18bb

      Remove read-only flag from non-keyspace cmds, different approach for EXEC to propagate MULTI (#8216)
      
      In the distant history there was only the read flag for commands, and whatever
      command that didn't have the read flag was a write one.
      Then we added the write flag, but some portions of the code still used !read
      Also some commands that don't work on the keyspace at all, still have the read
      flag.
      
      Changes in this commit:
      1. remove the read-only flag from TIME, ECHO, ROLE and LASTSAVE
      
      2. EXEC command used to decides if it should propagate a MULTI by looking at
         the command flags (!read & !admin).
         When i was about to change it to look at the write flag instead, i realized
         that this would cause it not to propagate a MULTI for PUBLISH, EVAL, and
         SCRIPT, all 3 are not marked as either a read command or a write one (as
         they should), but all 3 are calling forceCommandPropagation.
      
         So instead of introducing a new flag to denote a command that "writes" but
         not into the keyspace, and still needs propagation, i decided to rely on
         the forceCommandPropagation, and just fix the code to propagate MULTI when
         needed rather than depending on the command flags at all.
      
         The implication of my change then is that now it won't decide to propagate
         MULTI when it sees one of these: SELECT, PING, INFO, COMMAND, TIME and
         other commands which are neither read nor write.
      
      3. Changing getNodeByQuery and clusterRedirectBlockedClientIfNeeded in
         cluster.c to look at !write rather than read flag.
         This should have no implications, since these code paths are only reachable
         for commands which access keys, and these are always marked as either read
         or write.
      
      This commit improve MULTI propagation tests, for modules and a bunch of
      other special cases, all of which used to pass already before that commit.
      the only one that test change that uncovered a change of behavior is the
      one that DELs a non-existing key, it used to propagate an empty
      multi-exec block, and no longer does.

      TLS: Add different client cert support. (#8076) · 8c291b97
      Yossi Gottlieb authored
      This adds a new `tls-client-cert-file` and `tls-client-key-file`
      configuration directives which make it possible to use different
      certificates for the TLS-server and TLS-client functions of Redis.
      
      This is an optional directive. If it is not specified the `tls-cert-file`
      and `tls-key-file` directives are used for TLS client functions as well.
      
      Also, `utils/gen-test-certs.sh` now creates additional server-only and client-only certs and will skip intensive operations if target files already exist.

      Handle output buffer limits for Module blocked clients (#8141) · 48efc25f
      Oran Agra authored
      Module blocked clients cache the response in a temporary client,
      the reply list in this client would be affected by the recent fix
      in #7202, but when the reply is later copied into the real client,
      it would have bypassed all the checks for output buffer limit, which
      would have resulted in both: responding with a partial response to
      the client, and also not disconnecting it at all.

      Improve stability of new CSC eviction test (#8160) · a102b21d
      Oran Agra authored
      c4fdf09c added a test that now fails with valgrind
      it fails for two resons:
      1) the test samples the used memory and then limits the maxmemory to
         that value, but it turns out this is not atomic and on slow machines
         the background cron process that clean out old query buffers reduces
         the memory so that the setting doesn't cause eviction.
      2) the dbsize was tested late, after reading some invalidation messages
         by that time more and more keys got evicted, partially draining the
         db. this is not the focus of this fix (still a known limitation)
