      Converting more configs to use generic infra, and moving defaults to config.c · 18e72c5c
      Oran Agra authored
      Changes in behavior:
      - Change server.stream_node_max_entries from int64_t to long long, so that it can be used by the generic infra
      - standard error reply instead of "repl-backlog-size must be 1 or greater" and such
      - tls-port and a few TLS booleans were readable (config get) even when USE_OPENSSL was off (now they aren't)
      - syslog-enabled, syslog-ident, cluster-enabled, appendfilename, and supervised didn't have a get (now they do)
      - pidfile was initialized to NULL in InitServerConfig but had CONFIG_DEFAULT_PID_FILE in rewriteConfig (so the real default was "", but rewrite would cause it to be set), fixed the rewrite.
      - TLS config in server.h was uninitialized (if no tls config args were provided)
      
      Adding test for sanity and coverage

      More improvements and fixes to generic config infra · 28beb05a
      Oran Agra authored
      - Adding is_valid_fn and update_fn, both return 1 for success and 0 for failure with an optional error message.
      - Bugfix in handling boundary check of unsigned numeric types (was boundaries as signed)
      - Adding more numeric types to generic mechanism: uint, ulonglong, long, time_t, off_t
      - More verbose error replies ("argument must be between" in out of range CONFIG SET (like config file parsing)

      Additional config.c refactory and bugfixes · e0cc3c99
      Oran Agra authored
      - add capability for each config to have a callback to check if value is valid and return error string
        will enable converting many of the remaining custom configs into generic ones (reducing the x4 repetition for set,get,config,rewrite)
      - add capability for each config to  to run some update code after config is changed (only for CONFIG SET)
        will also enable converting many of the remaining custom configs into generic ones
      - add capability to move default values from server.h and server.c to config.c
        will reduce many excess lines in server.h and server.c (plus, no need to rebuild the entire code base when a default change 8-))
      
      other behavior changes:
      - fix bug in bool config get (always returning 'yes')
      - fix a bug in modifying jemalloc-bg-thread at runtime (didn't call set_jemalloc_bg_thread, due to bad merge conflict resolution (my fault))
      - side effect when a failed attempt to enable activedefrag at runtime, we now respond with -ERR and not with -DISABLED

      TLS: Improve CA certifiate configuration options. · d7f2681a
      Yossi Gottlieb authored
      This adds support for explicit configuration of a CA certs directory (in
      addition to the previously supported bundle file).  For redis-cli, if no
      explicit CA configuration is supplied the system-wide default
      configuration will be adopted.

      diskless replication rdb transfer uses pipe, and writes to sockets form the parent process. · 5a477946
      Oran Agra authored
      misc:
      - handle SSL_has_pending by iterating though these in beforeSleep, and setting timeout of 0 to aeProcessEvents
      - fix issue with epoll signaling EPOLLHUP and EPOLLERR only to the write handlers. (needed to detect the rdb pipe was closed)
      - add key-load-delay config for testing
      - trim connShutdown which is no longer needed
      - rioFdsetWrite -> rioFdWrite - simplified since there's no longer need to write to multiple FDs
      - don't detect rdb child exited (don't call wait3) until we detect the pipe is closed
      - Cleanup bad optimization from rio.c, add another one

      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

      make redis purge jemalloc after flush, and enable background purging thread · 09f99c2a
      Oran Agra authored
      jemalloc 5 doesn't immediately release memory back to the OS, instead there's a decaying
      mechanism, which doesn't work when there's no traffic (no allocations).
      this is most evident if there's no traffic after flushdb, the RSS will remain high.
      
      1) enable jemalloc background purging
      2) explicitly purge in flushdb

      ACL: add masteruser configuration for replication · ea9d3aef
      zhaozhao.zz authored
      In mostly production environment, normal user's behavior should be
      limited.
      
      Now in redis ACL mechanism we can do it like that:
      
          user default on +@all ~* -@dangerous nopass
          user admin on +@all ~* >someSeriousPassword
      
      Then the default normal user can not execute dangerous commands like
      FLUSHALL/KEYS.
      
      But some admin commands are in dangerous category too like PSYNC,
      and the configurations above will forbid replica from sync with master.
      
      Finally I think we could add a new configuration for replication,
      it is masteruser option, like this:
      
          masteruser admin
          masterauth someSeriousPassword
      
      Then replica will try AUTH admin someSeriousPassword and get privilege
      to execute PSYNC. If masteruser is NULL, replica would AUTH with only
      masterauth like before.
