      Modules: Add remaining list API functions (#8439) · ea36d4de
      Viktor Söderqvist authored
      List functions operating on elements by index:
      
      * RM_ListGet
      * RM_ListSet
      * RM_ListInsert
      * RM_ListDelete
      
      Iteration is done using a simple for loop over indices.
      The index based functions use an internal iterator as an optimization.
      This is explained in the docs:
      
      ```
       * Many of the list functions access elements by index. Since a list is in
       * essence a doubly-linked list, accessing elements by index is generally an
       * O(N) operation. However, if elements are accessed sequentially or with
       * indices close together, the functions are optimized to seek the index from
       * the previous index, rather than seeking from the ends of the list.
       *
       * This enables iteration to be done efficiently using a simple for loop:
       *
       *     long n = RM_ValueLength(key);
       *     for (long i = 0; i < n; i++) {
       *         RedisModuleString *elem = RedisModule_ListGet(key, i);
       *         // Do stuff...
       *     }
      ```

      Fix memory leak due to missing freeCallback in blockonbackground moduleapi test (#9499) · 1376d833
      sundb authored
      Before #9497, before redis-server was shut down, we did not manually shut down all the clients,
      which would have prevented valgrind from detecting a memory leak in the client's argc.

      Fixed leaked client for "start_server" when running in --loop (#9497) · 4c782758
      yoav-steinberg authored
      * On `kill_server` make sure we close the default `"client"` connection.
      * Don't reconnect when trying to execute the client's `close` command.
      * On `restart_server` make sure to remove the (closed) default `"client"` after killing the old server.

      PSYNC2: make partial sync possible after master reboot (#8015) · 794442b1
      zhaozhao.zz authored
      The main idea is how to allow a master to load replication info from RDB file when rebooting, if master can load replication info it means that replicas may have the chance to psync with master, it can save much traffic.
      
      The key point is we need guarantee safety and consistency, so there
      are two differences between master and replica:
      
      1. master would load the replication info as secondary ID and
         offset, in case other masters have the same replid.
      2. when master loading RDB, it would propagate expired keys as DEL
         command to replication backlog, then replica can receive these
         commands to delete stale keys.
         p.s. the expired keys when RDB loading is useful for users, so
         we show it as `rdb_last_load_keys_expired` and `rdb_last_load_keys_loaded` in info persistence.
      
      Moreover, after load replication info, master should update
      `no_replica_time` in case loading RDB cost too long time.

      bitpos/bitcount add bit index (#9324) · 75dd2309
      Huang Zhw authored
      Make bitpos/bitcount support bit index:
      
      ```
      BITPOS key bit [start [end [BIT|BYTE]]]
      BITCOUNT key [start end [BIT|BYTE]]
      ```
      
      The default behavior is `BYTE`, so these commands are still compatible with old.

      Replace all usage of ziplist with listpack for t_zset (#9366) · 3ca6972e
      sundb authored
      Part two of implementing #8702 (zset), after #8887.
      
      ## Description of the feature
      Replaced all uses of ziplist with listpack in t_zset, and optimized some of the code to optimize performance.
      
      ## Rdb format changes
      New `RDB_TYPE_ZSET_LISTPACK` rdb type.
      
      ## Rdb loading improvements:
      1) Pre-expansion of dict for validation of duplicate data for listpack and ziplist.
      2) Simplifying the release of empty key objects when RDB loading.
      3) Unify ziplist and listpack data verify methods for zset and hash, and move code to rdb.c.
      
      ## Interface changes
      1) New `zset-max-listpack-entries` config is an alias for `zset-max-ziplist-entries` (same with `zset-max-listpack-value`).
      2) OBJECT ENCODING will return listpack instead of ziplist.
      
      ## Listpack improvements:
      1) Add `lpDeleteRange` and `lpDeleteRangeWithEntry` functions to delete a range of entries from listpack.
      2) Improve the performance of `lpCompare`, converting from string to integer is faster than converting from integer to string.
      3) Replace `snprintf` with `ll2string` to improve performance in converting numbers to strings in `lpGet()`.
      
      ## Zset improvements:
      1) Improve the performance of `zzlFind` method, use `lpFind` instead of `lpCompare` in a loop.
      2) Use `lpDeleteRangeWithEntry` instead of `lpDelete` twice to delete a element of zset.
      
      ## Tests
      1) Add some unittests for `lpDeleteRange` and `lpDeleteRangeWithEntry` function.
      2) Add zset RDB loading test.
      3) Add benchmark test for `lpCompare` and `ziplsitCompare`.
      4) Add empty listpack zset corrupt dump test.

      Add LMPOP/BLMPOP commands. (#9373) · c50af0ae
      Binbin authored
      We want to add COUNT option for BLPOP.
      But we can't do it without breaking compatibility due to the command arguments syntax.
      So this commit introduce two new commands.
      
      Syntax for the new LMPOP command:
      `LMPOP numkeys [<key> ...] LEFT|RIGHT [COUNT count]`
      
      Syntax for the new BLMPOP command:
      `BLMPOP timeout numkeys [<key> ...] LEFT|RIGHT [COUNT count]`
      
      Some background:
      - LPOP takes one key, and can return multiple elements.
      - BLPOP takes multiple keys, but returns one element from just one key.
      - LMPOP can take multiple keys and return multiple elements from just one key.
      
      Note that LMPOP/BLMPOP  can take multiple keys, it eventually operates on just one key.
      And it will propagate as LPOP or RPOP with the COUNT option.
      
      As a new command, it still return NIL if we can't pop any elements.
      For the normal response is nested arrays in RESP2 and RESP3, like:
      ```
      LMPOP/BLMPOP 
      1) keyname
      2) 1) element1
         2) element2
      ```
      I.e. unlike BLPOP that returns a key name and one element so it uses a flat array,
      and LPOP that returns multiple elements with no key name, and again uses a flat array,
      this one has to return a nested array, and it does for for both RESP2 and RESP3 (like SCAN does)
      
      Some discuss can see: #766 #8824

      Delay to discard cached master when full synchronization (#9398) · cee3d67f
      Wang Yuan authored
      * Delay to discard cache master when full synchronization
      * Don't disconnect with replicas before loading transferred RDB when full sync
      
      Previously, once replica need to start full synchronization with master,
      it will discard cached master whatever full synchronization is failed or
      not. 
      Now we discard cached master only when transferring RDB is finished
      and start to change data space, this make replica could start partial
      resynchronization with another new master if new master is failed
      during full synchronization.

      Fix wrong offset when replica pause (#9448) · 1b83353d
      zhaozhao.zz authored
      When a replica paused, it would not apply any commands event the command comes from master, if we feed the non-applied command to replication stream, the replication offset would be wrong, and data would be lost after failover(since replica's `master_repl_offset` grows but command is not applied).
      
      To fix it, here are the changes:
      * Don't update replica's replication offset or propagate commands to sub-replicas when it's paused in `commandProcessed`.
      * Show `slave_read_repl_offset` in info reply.
      * Add an assert to make sure master client should never be blocked unless pause or module (some modules may use block way to do background (parallel) processing and forward original block module command to the replica, it's not a good way but it can work, so the assert excludes module now, but someday in future all modules should rewrite block command to propagate like what `BLPOP` does).

      Optimize quicklistIndex to seek from the nearest end (#9454) · 547c3405
      Viktor Söderqvist authored
      Until now, giving a negative index seeks from the end of a list and a
      positive seeks from the beginning. This change makes it seek from
      the nearest end, regardless of the sign of the given index.
      
      quicklistIndex is used by all list commands which operate by index.
      
      LINDEX key 999999 in a list if 1M elements is greately optimized by
      this change. Latency is cut by 75%.
      
      LINDEX key -1000000 in a list of 1M elements, likewise.
      
      LRANGE key -1 -1 is affected by this, since LRANGE converts the
      indices to positive numbers before seeking.
      
      The tests for corrupt dumps are updated to make sure the corrup
      data is seeked in the same direction as before.

      This commit mainly fixes empty keys due to RDB loading and restore command,
      which was omitted in #9297.
      
      1) When loading quicklsit, if all the ziplists in the quicklist are empty, NULL will be returned.
          If only some of the ziplists are empty, then we will skip the empty ziplists silently.
      2) When loading hash zipmap, if zipmap is empty, sanitization check will fail.
      3) When loading hash ziplist, if ziplist is empty, NULL will be returned.

      Here's a list of the fixes
      - Prevent an overflow when allocating a dict hashtable
      - Prevent OOM when attempting to allocate a huge string
      - Prevent a few invalid accesses in listpack
      - Improve sanitization of listpack first entry
      - Validate integrity of stream consumer groups PEL
      - Validate integrity of stream listpack entry IDs
      - Validate ziplist tail followed by extra data which start with 0xff

      sundb authored
      
      
      When we load rdb or restore command, if we encounter a length of 0, it will result in the creation of an empty key.
      This could either be a corrupt payload, or a result of a bug (see #8453 )
      
      This PR mainly fixes the following:
      1) When restore command will return `Bad data format` error.
      2) When loading RDB, we will silently discard the key.

      Make sure execute SLAVEOF command in the right order in psync2 test. (#9316) · d0244bfc
      Binbin authored
      
      
      The psync2 test has failed several times recently.
      In #9159 we only solved half of the problem.
      i.e. reordering of the replica that's already connected to
      the newly promoted master.
      
      Consider this scenario:
      0 slaveof 2
      1 slaveof 2
      3 slaveof 2
      4 slaveof 1
      0 slaveof no one, became a new master got a new replid
      2 slaveof 0, partial resync and got the new replid
      3 reconnect 2, inherit the new replid
      3 slaveof 4, use the new replid and got a full resync
      
      And another scenario:
      1 slaveof 3
      2 slaveof 4
      3 slaveof 0
      4 slaveof 0
      4 slaveof no one, became a new master got a new replid
      2 reconnect 4, inherit the new replid
      2 slaveof 1, use the new replid and got a full resync
      
      So maybe we should reattach replicas in the right order.
      i.e. In the above example, if it would have reattached 1, 3 and 0 to
      the new chain formed by 4 before trying to attach 2 to 1, it would succeed.
      
      This commit break the SLAVEOF loop into two loops. (ideas from oran)
      
      First loop that uses random to decide who replicates from who.
      Second loop that does the actual SLAVEOF command.
      In the second loop, we make sure to execute it in the right order,
      and after each SLAVEOF, wait for it to be connected before we proceed.

      Use madvise(MADV_DONTNEED) to release memory to reduce COW (#8974) · d4bca53c
      Wang Yuan authored
      
      
      ## Backgroud
      As we know, after `fork`, one process will copy pages when writing data to these
      pages(CoW), and another process still keep old pages, they totally cost more memory.
      For redis, we suffered that redis consumed much memory when the fork child is serializing
      key/values, even that maybe cause OOM.
      
      But actually we find, in redis fork child process, the child process don't need to keep some
      memory and parent process may write or update that, for example, child process will never
      access the key-value that is serialized but users may update it in parent process.
      So we think it may reduce COW if the child process release memory that it is not needed.
      
      ## Implementation
      For releasing key value in child process, we may think we call `decrRefCount` to free memory,
      but i find the fork child process still use much memory when we don't write any data to redis,
      and it costs much more time that slows down bgsave. Maybe because memory allocator doesn't
      really release memory to OS, and it may modify some inner data for this free operation, especially
      when we free small objects.
      
      Moreover, CoW is based on  pages, so it is a easy way that we only free the memory bulk that is
      not less than kernel page size. madvise(MADV_DONTNEED) can quickly release specified region
      pages to OS bypassing memory allocator, and allocator still consider that this memory still is used
      and don't change its inner data.
      
      There are some buffers we can release in the fork child process:
      - **Serialized key-values**
        the fork child process never access serialized key-values, so we try to free them.
        Because we only can release big bulk memory, and it is time consumed to iterate all
        items/members/fields/entries of complex data type. So we decide to iterate them and
        try to release them only when their average size of item/member/field/entry is more
        than page size of OS.
      - **Replication backlog**
        Because replication backlog is a cycle buffer, it will be changed quickly if redis has heavy
        write traffic, but in fork child process, we don't need to access that.
      - **Client buffers**
        If clients have requests during having the fork child process, clients' buffer also be changed
        frequently. The memory includes client query buffer, output buffer, and client struct used memory.
      
      To get child process peak private dirty memory, we need to count peak memory instead
      of last used memory, because the child process may continue to release memory (since
      COW used to only grow till now, the last was equivalent to the peak).
      Also we're adding a new `current_cow_peak` info variable (to complement the existing
      `current_cow_size`)

      Fix tests failure on 32bit build (#9318) · 56eb7f7d
      Meir Shpilraien (Spielrein) authored
      Fix test introduced in #9202 that failed on 32bit CI.
      The failure was due to a wrong double comparison.
      Change code to stringify the double first and then compare.

      Unified Lua and modules reply parsing and added RESP3 support to RM_Call (#9202) · 2237131e
      Meir Shpilraien (Spielrein) authored
      
      
      ## Current state
      1. Lua has its own parser that handles parsing `reds.call` replies and translates them
        to Lua objects that can be used by the user Lua code. The parser partially handles
        resp3 (missing big number, verbatim, attribute, ...)
      2. Modules have their own parser that handles parsing `RM_Call` replies and translates
        them to RedisModuleCallReply objects. The parser does not support resp3.
      
      In addition, in the future, we want to add Redis Function (#8693) that will probably
      support more languages. At some point maintaining so many parsers will stop
      scaling (bug fixes and protocol changes will need to be applied on all of them).
      We will probably end up with different parsers that support different parts of the
      resp protocol (like we already have today with Lua and modules)
      
      ## PR Changes
      This PR attempt to unified the reply parsing of Lua and modules (and in the future
      Redis Function) by introducing a new parser unit (`resp_parser.c`). The new parser
      handles parsing the reply and calls different callbacks to allow the users (another
      unit that uses the parser, i.e, Lua, modules, or Redis Function) to analyze the reply.
      
      ### Lua API Additions
      The code that handles reply parsing on `scripting.c` was removed. Instead, it uses
      the resp_parser to parse and create a Lua object out of the reply. As mentioned
      above the Lua parser did not handle parsing big numbers, verbatim, and attribute.
      The new parser can handle those and so Lua also gets it for free.
      Those are translated to Lua objects in the following way:
      1. Big Number - Lua table `{'big_number':'<str representation for big number>'}`
      2. Verbatim - Lua table `{'verbatim_string':{'format':'<verbatim format>', 'string':'<verbatim string value>'}}`
      3. Attribute - currently ignored and not expose to the Lua parser, another issue will be open to decide how to expose it.
      
      Tests were added to check resp3 reply parsing on Lua
      
      ### Modules API Additions
      The reply parsing code on `module.c` was also removed and the new resp_parser is used instead.
      In addition, the RedisModuleCallReply was also extracted to a separate unit located on `call_reply.c`
      (in the future, this unit will also be used by Redis Function). A nice side effect of unified parsing is
      that modules now also support resp3. Resp3 can be enabled by giving `3` as a parameter to the
      fmt argument of `RM_Call`. It is also possible to give `0`, which will indicate an auto mode. i.e, Redis
      will automatically chose the reply protocol base on the current client set on the RedisModuleCtx
      (this mode will mostly be used when the module want to pass the reply to the client as is).
      In addition, the following RedisModuleAPI were added to allow analyzing resp3 replies:
      
      * New RedisModuleCallReply types:
         * `REDISMODULE_REPLY_MAP`
         * `REDISMODULE_REPLY_SET`
         * `REDISMODULE_REPLY_BOOL`
         * `REDISMODULE_REPLY_DOUBLE`
         * `REDISMODULE_REPLY_BIG_NUMBER`
         * `REDISMODULE_REPLY_VERBATIM_STRING`
         * `REDISMODULE_REPLY_ATTRIBUTE`
      
      * New RedisModuleAPI:
         * `RedisModule_CallReplyDouble` - getting double value from resp3 double reply
         * `RedisModule_CallReplyBool` - getting boolean value from resp3 boolean reply
         * `RedisModule_CallReplyBigNumber` - getting big number value from resp3 big number reply
         * `RedisModule_CallReplyVerbatim` - getting format and value from resp3 verbatim reply
         * `RedisModule_CallReplySetElement` - getting element from resp3 set reply
         * `RedisModule_CallReplyMapElement` - getting key and value from resp3 map reply
         * `RedisModule_CallReplyAttribute` - getting a reply attribute
         * `RedisModule_CallReplyAttributeElement` - getting key and value from resp3 attribute reply
         
      * New context flags:
         * `REDISMODULE_CTX_FLAGS_RESP3` - indicate that the client is using resp3
      
      Tests were added to check the new RedisModuleAPI
      
      ### Modules API Changes
      * RM_ReplyWithCallReply might return REDISMODULE_ERR if the given CallReply is in resp3
        but the client expects resp2. This is not a breaking change because in order to get a resp3
        CallReply one needs to specifically specify `3` as a parameter to the fmt argument of
        `RM_Call` (as mentioned above).
      
      Tests were added to check this change
      
      ### More small Additions
      * Added `debug set-disable-deny-scripts` that allows to turn on and off the commands no-script
      flag protection. This is used by the Lua resp3 tests so it will be possible to run `debug protocol`
      and check the resp3 parsing code.
