      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.
