      RFC: FutureDAG · f51b0466
      James Sedgwick authored
      Summary:
      See task. Set up a DAG of Future-returning tasks (optionally with executors) and eventually kick them off.
      One big question is ownership. Currently the user would be responsible for ensuring that the FutureDAG outlives its own completion. This requirement could go away with shared_from_this magic maybe
      
      Test Plan: unit. I didn't bother to test via() functionality because it's too much work for now - the functionality is trivial. Same for "true-async" dags...

      Make folly::format no longer crash on invalid format strings · 4ecf6e3f
      Tudor Bosman authored
      Summary:
      Yes, ideally we'd detect this at compile time, but if we can't, causing a SEV1
      is not the best way to do it.
      
      format() now behaves like formatChecked(); the old API is maintained for
      backwards compatibility, but deprecated.

      Fix race issue in EventBase::runInEventBaseThreadAndWait (t6779663) · 1ae1c1ff
      Alan Frindell authored
      Summary: Huge thanks to @afrind for debugging this issue with me and found the root cause. As per the comment from @afrind for the diff D1823407, there is a tricky race issue. The main thread could have left and reset the condition_variable from its stack but the EventBase thread tries to access it afterwards due to race and could be blocked indefinitely. This caused the server-side IO threads not able to pick up the incoming connections for the proxygen case. The fix is to use a simpler struct barrier and get a hold of the shared_ptr instead of the same object in a safer way.
      
      Test Plan:
      The original issue reproes very easily in HDFS XDC encryption case. Servers easily enter into bad state and we got high volume of timeouts from the client. With the fix, this does not happen anymore after the fix being deployed at 11:15PM. Here is the Scuba log before and after the fix:
      https://fburl.com/109969805
      And here is the correspond Scuba diagram for successful calls in the same test:
      https://fburl.com/109971729
      The throughput improved a lot after the fix.

      (Wangle) unorderedReduce · e872b440
      Hannes Roth authored
      Summary:
      Use this if you don't need the order of the input, e.g. summing up
      values. This constructs a separate Future chain to do the reducing,
      because we don't want to add locking while reducing. The only lock
      necessary is when adding a new Future to the chain, which should be
      really quick.
      
      Test Plan: Run all the tests.

      (Wangle) chain -> thenMulti + thenMultiWithExecutor · 0593c224
      Hannes Roth authored
      Summary:
      If we make `chain` a member function we can avoid the type issues and infer everything. I also added thenMulti for symmetry. Sadly the compiler doesn't like having a thenMulti with an optional `Executor*` as the first argument, it fails after some deductions. Hence `thenMultiWithExecutor`.

      via with priority · c8250894
      James Sedgwick authored
      Summary:
      I wish I could just have an add(Func, priority) but the damned overloaded virtual warnings become a nightmare, so it's addWithPriority.
      I also switched priority to a uint8_t in the hopes of reducing Core size. Turns out std::atomic<uint8_t> is 8 bytes anyways :( I left it that way because come on you really shouldn't be using > 256 priorities.
      Biggest problem is the data race with the two atomics executor_ and priority_. Should we just use a microspinlock to co-protect them? Could probably save some size from the atomics that way.

      transportActive and transportInactive · 1185881d
      James Sedgwick authored
      Summary:
      These are equivalents to Netty's channelActive and channelInactive, but we've been calling channels transports so I'm staying consistent.
      I skipped integrating this into TAsyncTransportHandler because thrift still does manual CB attachment/detachment and it's unclear how that fits into this model
      If my suspicions are correct, it *should* be possible to make attachReadCallback and detachReadCallback private in AsyncSocketHandler, right? And perhaps get rid of the event base modifier methods? What's our use case for those?

      (Wangle) Implement collect* using mapSetCallback and shared_ptrs · 4a92da5b

      I figured it would make sense to implement all the collect* functions using a shared_ptr<Context>, instead of doing our manual reference counting and all that. Fulfilling the promise in the destructor seemed like the icing on the cake. Also saves some line of code.
      
      Test Plan: Run all the tests.

      Summary:
      In order to create an EventBase'd Suprocess class, I'd like to be able to manage the lifetime of pipes independently of the lifetime of the process. To this effect, I factored out basic Pipe handling, and provided a function that detaches the pipe vector from the Subprocess object.

      Destructor DCHECKs for EBADF · ec3c8f79
      Alexey Spiridonov authored
      Summary: This almost always indicates a double-close bug, or a similarly nasty logic error. I don't dare make it a check, we may have some code running in production which would be broken by the CHECK, but this should give us early warning of any such bugs.
      
      Test Plan:
      ```
      fbconfig folly/test:file_test folly/test:file_util_test
      fbmake runtests && fbmake runtests_opt
      ```
      
      This test used to pass until @tudorb made me remove it due to worries about death tests messing with (currently absent) multi-threading:
      
      ```
      +
      +void testDoubleClose() {
      +  File f("/dev/null");
      +  checkUnixError(close(f.fd()));  // This feels so... wrong!
      +  // The destructor will now try to double-close.
      +}
      +
      +TEST(File, DCHECKDoubleClose) {
      +#ifndef NDEBUG
      +  // This test makes no sense otherwise, since this is a DCHECK.
      +  EXPECT_DEATH(testDoubleClose(), "double-close-FD");
      +#else
      +  // That sound you hear is millions of lemmings falling to their doom.
      +  testDoubleClose();
      +#endif
      +}

      update FunctionScheduler to use std::chrono::steady_clock · be171a18
      Adam Simpkins authored
      Summary:
      Use std::chrono::steady_clock instead of clock_gettime(CLOCK_MONOTONIC).
      In particular this fixes the build on Mac OS X, which doesn't have
      CLOCK_MONOTONIC.
      
      This also updates the code to use steady_clock::time_point correctly, instead
      of using a raw milliseconds value for time since the epoch.
      
      Test Plan:
      Included unit tests, which were copied over from the legacy internal Facebook
      (non-folly) version of this code.

      OS X doesn't support constructor priorities · c9f8c1db
      Josh Watzman authored
      Summary:
      OS X doesn't support constructor init priorities, at all. AIUI,
      it's a limitation of their actual binary format and loader, not just a
      tooling/compiler limitation.
      
      This particular usage appears to just be for for logging/bug-finding
      purposes, so it looks like just removing the priority on OS X isn't the
      end of the world?
      
      Test Plan: g++-4.9 on OS X compiles this file now.

      (Wangle) Fix Executor problem · e4e2520a
      Hannes Roth authored
      Summary:
      None of these functions should be templated with `class Executor`.
      Except `then(Executor, Args...)` because otherwise the compiler gets
      confused. This was the combination that worked for both Clang and GCC,
      don't ask me why. I'm assuming this puts it on a low priority...
      
      I think this is also OK, because `setExecutor` takes an actual
      `folly::Executor`, so even `then(Executor, Args...)` won't just work for any
      `Executor`.
