      IPAddressV6::kToFullyQualifiedSize. · 8ab68e82
      Yedidya Feldblum authored
      Summary:
      [Folly] IPAddressV6::kToFullyQualifiedSize.
      
      The scenario: One has a string known to be a fully-qualified IPv4 or fully-qualified IPv6 address, but one does not know which of the two it is.
      
      The dirty but fast solution: just check its size.

      Make MIN_WRITE_SIZE configurable for AsyncSSLSocket. · 12f0c056
      Jun Li authored
      Summary:
      MIN_WRITE_SIZE is used to avoid small write calls to SSL_write. If there are
      consecutive small buffers to write, then will be combined together(by being
      copied to a local buffer) until total size exceeds MIN_WRITE_SIZE. This reduces
      number of calls SSL_write, improving performance, and avoiding overhead in OpenSSL.
      
      Currently, MIN_WRITE_SIZE is hard coded to be 1500 bytes.
      
      Wormhole could benefit from this, as our average message size is several
      hundreds of bytes. We could get even better throughput with larger
      MIN_WRITE_SIZE.
      
      As discussed with Adam and Alan, there is a good reason to make it
      configurable, though default value is still 1500.

      Assume exception when Executor::add throws · df50885c
      Hans Fugal authored
      Summary:
      Rather than crashing spectacularly, if `Executor::add` throws (e.g. because the queue is full), then discard the result we got and assume the exception the executor threw instead.
      
      Alternatively, we could pass this exceptional Try to the callback (without an executor, as it is here), but not perturb `result_`. This would mean two different world views in these two code snippets:
      
      auto f1 = makeFuture(42).via(&crappyExecutor);
      f1.value(); // 42 (no callback happened)
      f1.then(...); // would see the executor's exception. Would also be ill-advised to do this after value()
      
      auto f2 = makeFuture(42).via(&crappyExecutor)
      .then([](int x) { return x * 2; }); // skipped
      f2.value(); // throws executor's exception
      
      It feels rude to throw away the result, but it feels too potentially dangerous to allow this split view of the world.

      We might avoid some temporaries in putMessagesImpl · 0011d8a0
      Nicholas Ormrod authored
      Summary:
      This is folly github pull request https://github.com/facebook/folly/pull/184
      
      It seems we might avoid some temporaries in putMessagesImpl
      function. To do so we pass arguments directly to constructors
      with the help of emplace_back member.
      
      Test Plan:
      All folly/tests, make check for 37 tests, passed.

      fix race in ~ThreadWheelTimekeeper · 30d8a3d6
      Louis Brandy authored
      Summary:
      During destruction, we enqueue a callback to `eventBase_` that references `wheelTimer_`.
      
      So long as that callback exists, we have a circular dependency as both reference the other and we -cannot- safely destroy this object (and its members). The fix is to break this dependency someway. In this case, I've chosen to simply `AndWait` until the eventBase has consumed the message referencing the timer. From here normal destruction of members can proceed safely (destorying HHWheelTimer first, EventBase second).
      
      The problem in the current code is that the Eventbase will attempt to consume all messages during it's own destruction. If `wheelTimer_->cancelAll()` is still enqueued, it will attempt to use the now destroyed `wheelTimer_`.
      
      Test Plan:
      Running this test repeatedly was able to repro:
