      XADD with ID 0-0 stores an empty key · 4a12047c
      Guy Benoish authored
      Calling XADD with 0-0 or 0 would result in creating an
      empty key and storing it in the database.
      Even worse, because XADD will reply with error the action
      will not be replicated, creating a master-replica
      inconsistency

      Add RM_ScanKey to scan hash, set, zset, changes to RM_Scan API · 0f8692b4
      Oran Agra authored
      - Adding RM_ScanKey
      - Adding tests for RM_ScanKey
      - Refactoring RM_Scan API
      
      Changes in RM_Scan
      - cleanup in docs and coding convention
      - Moving out of experimantal Api
      - Adding ctx to scan callback
      - Dont use cursor of -1 as an indication of done (can be a valid cursor)
      - Set errno when returning 0 for various reasons
      - Rename Cursor to ScanCursor
      - Test filters key that are not strings, and opens a key if NULL

      Added scan implementation to module api. · 11c6ce81
      meir@redislabs.com authored
      The implementation expose the following new functions:
      1. RedisModule_CursorCreate - allow to create a new cursor object for
      keys scanning
      2. RedisModule_CursorRestart - restart an existing cursor to restart the
      scan
      3. RedisModule_CursorDestroy - destroy an existing cursor
      4. RedisModule_Scan - scan keys
      
      The RedisModule_Scan function gets a cursor object, a callback and void*
      (used as user private data).
      The callback will be called for each key in the database proving the key
      name and the value as RedisModuleKey.

      Update PR #6537: use a fresh time outside call(). · 8b2c0f90
      antirez authored
      One problem with the solution proposed so far in #6537 is that key
      lookups outside a command execution via call(), still used a cached
      time. The cached time needed to be refreshed in multiple places,
      especially because of modules callbacks from timers, cluster bus, and
      thread safe contexts, that may use RM_Open().
      
      In order to avoid this problem, this commit introduces the ability to
      detect if we are inside call(): this way we can use the reference fixed
      time only when we are in the context of a command execution or Lua
      script, but for the asynchronous lookups, we can still use mstime() to
      get a fresh time reference.

      Update PR #6537 patch to for generality. · 824f5f0b
      antirez authored
      After the thread in #6537 and thanks to the suggestions received, this
      commit updates the original patch in order to:
      
      1. Solve the problem of updating the time in multiple places by updating
      it in call().
      2. Avoid introducing a new field but use our cached time.
      
      This required some minor refactoring to the function updating the time,
      and the introduction of a new cached time in microseconds in order to
      use less gettimeofday() calls.

      expires: refactoring judgment about whether a key is expired · e542132b
      zhaozhao.zz authored
      Calling lookupKey*() many times to search a key in one command
      may get different result.
      
      That's because lookupKey*() calls expireIfNeeded(), and delete
      the key when reach the expire time. So we can get an robj before
      the expire time, but a NULL after the expire time.
      
      The worst is that may lead to Redis crash, for example
      `RPOPLPUSH foo foo` the first time we get a list form `foo` and
      hold the pointer, but when we get `foo` again it's expired and
      deleted. Now we hold a freed memory, when execute rpoplpushHandlePush()
      redis crash.
      
      To fix it, we can refactor the judgment about whether a key is expired,
      using the same basetime `server.cmd_start_mstime` instead of calling
      mstime() everytime.

      Module API for loading and saving long double · 779aebc9
      Oran Agra authored
      looks like each platform implements long double differently (different bit count)
      so we can't save them as binary, and we also want to avoid creating a new RDB
      format version, so we save these are hex strings using "%La".
      
      This commit includes a change in the arguments of ld2string to support this.
      as well as tests for coverage and short reads.

      Modules hooks: complete missing hooks for the initial set of hooks · 51c3ff8d
      Oran Agra authored
      * replication hooks: role change, master link status, replica online/offline
      * persistence hooks: saving, loading, loading progress
      * misc hooks: cron loop, shutdown, module loaded/unloaded
      * change the way hooks test work, and add tests for all of the above
      
      startLoading() now gets flag indicating what is loaded.
      stopLoading() now gets an indication of success or failure.
      adding startSaving() and stopSaving() with similar args and role.

      Module API for controlling LRU and LFU, and OpenKey without TOUCH · e978bdf9
      Oran Agra authored
      Some commands would want to open a key without touching it's LRU/LFU
      similarly to the OBJECT or DEBUG command do.
      
      Other commands may want to implement logic similar to what RESTORE
      does (and in the future MIGRATE) and get/set the LRU or LFU.
