      Modules: Add RM_GetDetachedThreadSafeContext(). (#7886) · 907da058
      Yossi Gottlieb authored
      The main motivation here is to provide a way for modules to create a
      single, global context that can be used for logging.
      
      Currently, it is possible to obtain a thread-safe context that is not
      attached to any blocked client by using `RM_GetThreadSafeContext`.
      However, the attached context is not linked to the module identity so
      log messages produced are not tagged with the module name.
      
      Ideally we'd fix this in `RM_GetThreadSafeContext` itself but as it
      doesn't accept the current context as an argument there's no way to do
      that in a backwards compatible manner.

      Modules: add RM_GetCommandKeys(). · 7d117d75
      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).

      Fix RM_ScanKey module api not to return int encoded strings · a89bf734
      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.

      Fix memory corruption in moduleHandleBlockedClients · c4dc5b80
      Guy Benoish authored
      By using a "circular BRPOPLPUSH"-like scenario it was
      possible the get the same client on db->blocking_keys
      twice (See comment in moduleTryServeClientBlockedOnKey)
      
      The fix was actually already implememnted in
      moduleTryServeClientBlockedOnKey but it had a bug:
      the funxction should return 0 or 1 (not OK or ERR)
      
      Other changes:
      1. Added two commands to blockonkeys.c test module (To
         reproduce the case described above)
      2. Simplify blockonkeys.c in order to make testing easier
      3. cast raxSize() to avoid warning with format spec

      ld2string should fail if string contains \0 in the middle · 2deb5551
      Guy Benoish authored
      This bug affected RM_StringToLongDouble and HINCRBYFLOAT.
      I added tests for both cases.
      
      Main changes:
      1. Fixed string2ld to fail if string contains \0 in the middle
      2. Use string2ld in getLongDoubleFromObject - No point of
         having duplicated code here
      
      The two changes above broke RM_SaveLongDouble/RM_LoadLongDouble
      because the long double string was saved with length+1 (An innocent
      mistake, but it's actually a bug - The length passed to
      RM_SaveLongDouble should not include the last \0).

      Modules: Fix blocked-client-related memory leak · d7d13721
      Guy Benoish authored
      If a blocked module client times-out (or disconnects, unblocked
      by CLIENT command, etc.) we need to call moduleUnblockClient
      in order to free memory allocated by the module sub-system
      and blocked-client private data
      
      Other changes:
      Made blockedonkeys.tcl tests a bit more aggressive in order
      to smoke-out potential memory leaks

      Improve RM_ModuleTypeReplaceValue() API. · 0283db58
      Yossi Gottlieb authored
      With the previous API, a NULL return value was ambiguous and could
      represent either an old value of NULL or an error condition. The new API
      returns a status code and allows the old value to be returned
      by-reference.
      
      This commit also includes test coverage based on
      tests/modules/datatype.c which did not exist at the time of the original
      commit.

      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.

      rename RN_SetLRUOrLFU -> RM_SetLRU and RN_SetLFU · 28c20b4e
      Oran Agra authored
      - the API name was odd, separated to two apis one for LRU and one for LFU
      - the LRU idle time was in 1 second resolution, which might be ok for RDB
        and RESTORE, but i think modules may need higher resolution
      - adding tests for LFU and for handling maxmemory policy mismatch

      fix leak in module api rdb test · 02f21113
      Oran Agra authored
      recently added more reads into that function, if a later read fails, i must
      either free what's already allocated, or return the pointer so that the free
      callback will release it.

      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.
