      attempt at putting thrift2 on ChannelPipeline · 0f3fabf1
      Dave Watson authored
      Summary:
      Basically a ripoff of Dave's D1483148 but with ChannelPipeline instead of rx.
      There's going to be a long tail of unit tests here, this is still pretty broken...
      
      Not convinced that this is the way to go but I wanted to get a feel for what it would be like to plug it into an IRL system.
      I think the simplicity/clarity of the handler implementations and to some extent the pipeline spec is an improvement over the rx way
      but I'm less sure about everything else.
      
      Test Plan: compiles and kind of works some of the time but not really

      EventBase::runAfterDelay to throw an exception · 1a61493f
      Haim Grosman authored
      Summary:
      EventBase::runAfterDelay to throw an exception in case it fails to
      schedule a proper execution of the given callback
      (instead of silently returning false)
      
      it appears to be the right thing to do, since:
      @davejwatson: Digging through the layers of code, it appears this can only fail if
      epoll_ctl() with EPOLL_CTL_ADD fails. Ignoring libevent bugs, it looks
      like the only relevant errors could be ENOMEM or ENOSPC. So
      nonrecoverable

      Summary:
      Updating Folly Formatting's use of separators for Decimal Integers 'd' and Numbers 'n'.
      Updated Decimal Integers 'd' use of separators to directly use commas ',' and grouping of 3 digits.
      Updated Numbers use of separators and grouping to follow locale settings.
      
      Test Plan:
      Wrote unit tests to validate the insertion of thousandsSeparators works.
      Note that the numbers unit test does not modify the locale since the test cases are not thread safe.

      Add AutoTimer to folly · 215e9064
      Andrey Goder authored
      Summary:
      This 'moves' bistro::AutoTimer into folly. I actually changed it a bit, so I'm
      not migrating any existing uses in this diff, but I can do that as a followup.
      We're using it in various places now, so it doesn't make sense to have it in
      bistro.
      
      Basically this class lets you conveniently time a series of things while
      printing log messages, e.g.:
      {
      AutoTimer t("Done");
      processA();
      t.log("processA() complete");
      }
      
      would print
      "processA() complete in XXX seconds"
      "Done in YYY seconds"
      
      I changed some things from bistro::AutoTimer:
      - Use std::chrono::time_point<Clock> to store the start time.
      - I removed the gflags. It seems weird to rely on those to control the timer,
      since they would affect all uses of this. If a specific user of the timer
      wants to actually control timing at runtime, I think it's better to use a
      custom logger.
      - I removed the 'min log duration'. As implemented it actually made the
      constructor conflict: AutoTimer("foo", 1.2) is ambiguous. Also, it should
      probably be set on the logger, so this likewise feels like a place where you
      could make a custom logger.
      
      I'm not sure that the way I use the default logger as a template argument is
      best, so please suggest improvements to that.

      (futures) Make executors sticky · fc6f0a5f
      Hans Fugal authored
      Summary:
      Instead of returning a deactivated future, have `via` just set the executor. Propagate the executor from `then`. This fixes the `via().get()` problem, and has semantics similar to before for `via().then().then()`.
      
      However, the semantics are now slightly different - each `then` goes back through the executor. This adds some overhead and tweaks the semantics (e.g. if the executor is a threadpool it might execute subsequent `then`s in another thread). However, with `futures::chain` recently introduced, and any other convenience methods that you can dream up and make a case for, we can reasonably get the old once-through-the-executor behavior when performance or other concerns demand it. e.g. `via().then(futures::chain(a, b, c))`.

      Summary:
      Use server bootstrap.
      
      * code reuse
      * Allows multiple accept threads easily.
      
      Accept now doesn't happen in the server's eventBase, but a new thread.
      
      I think I hit all the corner cases involving existingSocket, duplex, stopListening(), etc.
      
      There are a lot of minor changes here to support all the cases, let me know if I should split anything to separate diffs

      the expansion of EXPECT_EQ applies sizeof to an expression
      with side effects:

      Test Plan:
      Ensure this compiles with clang-3.4, 3.5 and clang:dev.
      I.e., ensure that this prints PASS at the end.

      missing "override" keyword.  However, in
      folly/wangle/channel/test/MockChannelHandler.h, I chose
      to ignore those warnings for the mocked functions.

      pass along additional info from the setup if necessary.
      
      Test Plan:
      Run proxygen on my devserver listening on ipv4 and ipv6 for ports 80 and 443.
      Configure it to run a lua request rule with the following lines:
      
      io.stderr:write("jonlog: proxy " .. conn:getClientAddrOriginal() .. "\n")
      io.stderr:write("jonlog: client " .. request:getClientIPStr() .. "\n")
      
      Run haproxy also on my devserver, listening on ports 8555-8558, with each
      forwarding to one of the four pairs (ipv4-localhost/ipv6-localhost, 80/443)
      
      From my laptop, run curls against each of these four endpoints and make
      sure that we print out "127.0.0.1" as the proxy IP, and my laptop's IP
      as the client IP.

      Fix EliasFanoReader position() when past-the-end · c7c65f54
      Giuseppe Ottaviano authored
      Summary:
      `EliasFanoReader::position()` used to return `size() - 1` both when
      the reader is positioned on the last element, and after `next()` is
      called after that (and it return `false`). Now in the latter case
      `position()` returns `size()` (consistently with the usual behaviour
      of past-the-end iterators).
      
      Also fix the return type of `jumpTo`.
      
      Test Plan:
      fbconfig folly/experimental/test:eliasfano_test && fbmake runtests_opt
