Add additional instantiations in Instantiations.cpp
Summary:
Histogram::getPercentileBucketIdx() and getPercentileEstimate() are
implemented using template methods of HistogramBuckets.
This updates Instantiations.cpp to also instantiate the versions of
these template methods that are required by Histogram<int64_t>. Without
this, anyone using these methods was required to also include
Histogram-defs.h, or otherwise they may get link errors. This makes it
so they no longer need to include Histogram-defs.h
The C++ syntax required is pretty horrendous. We could potentially
avoid this by refactoring the code so that these methods are no longer
templates (and require that the Bucket class provide methods for this
purpose). At the moment adding instantiations seems simpler, and
doesn't change any public APIs.

getVia() and waitVia()
Summary:
Introduce ProgressableExecutor, which is an Executor that can be driven somehow. Examples include EventBase and ManualExecutor
Then introduce Future<T>::getVia(ProgressableExecutor*) and Future<T>::waitVia(ProgressableExecutor*) that drive the given executor until the Future is complete, with the usual semantics of get and wait respectively
This is a really common pattern in tests and you can see in the various changes to other projects lends sopme nice redness and cleanliness
Some notes:
1. I don't like ProgressableExecutor::makeProgress() that much. Too verbose. Maybe DrivableExecutor::drive()? Something else? Thoughts?
2. I still need to integrate this with some stuff in Zeus (SessionFuture) and Zookeeper (ZookeeperFuture) but I'm going to do that in a separate diff because it's going to be a little more intrusive
3. These APIs take a raw ptr so that they are consistent with via()

codecs
Summary:
Start of codec framework. Copied the frame based codecs almost exactly from netty, but made to fit our pipeline management.
BytesToMessageCodec is slightly different: Netty preprocesses all the available data to a List<Message>, while this codec a) Only does one message at a time to avoid queueing issues, and b) doesn't template the message type, and just passes an IOBuf
I'm fighting the type system to get the pipelines to play nice to each other: I'd rather template the message type, but it prevents stacking outgoing handlers on top of it, since you ahve to specify both the input/output type for each handler, even if you only care about the output type. Suggestions to fix? Netty gets around this by lots of dynamic casting to Object type, but we can't do that in C++ since we don't have a base object type

Try to fix IdleTime unit test
Summary:
IdleTime unit test has been failing randomly (#
5996886). The
event base loop calculates an exponentially moving average of loop busy
time in each loop. In the test, the busy time is initialized to 5900 and
each loop runs more than 8000 us. In normal case decaying of the
previous loop busy time will take 6 loops to move this average to >6000.
But if the test is running on a heavily loaded machine the busy+idle time
a loop is longer than it should be, causing the decaying happen faster.
This diff skips this test if this happens.
Test Plan:
It won't affect anything if running on my devserver. It only
helps on a heavily loaded contbuild host.

apply all sockopts to listening sockets
Summary:
We want all socket options to be applied to the listen sockets too.
The old code here that only applied SO_KEEPALIVE is a bit superstitious.
Not all options will be inherited by accept()ed sockets, but that's
fine. We set them again post-accept().
Applying all these options to the listening sockets will fix at least
one long standing bug, which is that QoS is not set correctly for the
first few packets in a flow. This also will let us do the right thing
when we gain the ability to set TCP_MAXSEG in

folly: Bits: restore type of bitOffset_ to shorter "unsigned int"
Summary:
My initial change to avoid the -Wsign-compare error neglected
the fact that the difference of two unsigned types is also
unsigned. That broke some unicorn tests, as seen in
D1776343,
which worked around the problem by changing the type of
bitOffset_ like this: s/unsigned int/size_t.
The real problem lay in the distance_to function, which computed
the signed difference of two bitOffset_ values.
To work properly with the narrower unsigned type,
we could either first widen each operand to ssize_t
before computing their parenthesized difference, or
(as Philip suggested and I prefer), just drop the
parentheses and let the signedness of the preceding
operands ensure that each successive intermediate
result is also signed.
Test Plan:
Choose one of the failing tests, and ensure it now passes:
fbconfig -r unicorn/diskindex4/test:doc_map_test
fbmake runtests
Also run all unicorn tests, for good measure (still waiting):
fbconfig -r unicorn && fbmake runtests

MPMCQueue.h: fix a bug introduced while accommodating -Wsign-compare
Summary:
* folly/MPMCQueue.h (waitForTurn): My changes to accommodate
-Wsign-compare introduced a bug that could cause lots of wasted CPU.
(See @scottf's comments on the blamed patch.)
Subtraction involving an unsigned type will always yield an unsigned
result, and there was at least this one instance where the result
would sometimes have to be a small negative number. Instead, we'd
get approximately UINT32_MAX. The fix is to explicitly cast the
difference to a signed type.
Test Plan:
Run this and note there is no error:
(this ensures it remains -Wsign-compare-clean with gcc-4.9)
fbconfig --platform-all=gcc-4.9-glibc-2.20 tao/server && fbmake dbgo
Before this change, running the mpmc_queue_test test would get
timeout errors ~8 in 100 runs. Confirm that with this patch, now
there is no type of failure. I.e., run these commands and ensure
the grep prints nothing:
fbconfig folly/test:mpmc_queue_test
for i in $(seq 100); do fbmake runtests_dbgo >& makerr-$i; done

This is part of that clean-up. Some of these changes fix the problem

The fix is to use an unsigned type when the limit is also unsigned.

uint64_t unless you have a very good reason to require them.

Histogram and Timeseries vs gcc-4.9 and -Wsign-compare
Summary:
Address multiple -Werror=sign-compare issues exposed when building
tao with gcc-4.9.
In most of these changes I've changed the type of the index in
a for-loop from int to size_t. The important thing is to use
an unsigned type when the limit is also unsigned. I choose size_t
because the general recommendation (when writing portable code)
to avoid size-tied types like uint32_t and uint64_t unless you
have a very good reason to require them.

Fixes T5922800

Test Plan:
TBH I don't know why detaching a temporary thread variable might cause the program to abort but this seems to be the most likely cause so I'm making this change and we'll see in a day or two if it fixes it.
The test still passes and doesn't hang

I suppressed "comparison between signed and unsigned integer expressions" warnings for this first pass because there a whole lot (dozens) of those. Do we suppress those with 4.8 or something? Never seen the warnings before.
I can't find anything in boost 1.57 docs/changelog indicating why implicit conversion of boost::optional<bool> -> bool doesn't compile anymore, but it doesn't.

(folly) osx bootstrap script
Summary:
This is a bootstrap script for building folly on osx. I attempted to make it Just Work⢠for anyone who uses Homebrew (http://brew.sh/) but even if it doesn't work out of the box it should be instructive for the motivated developer on OSX.
Facebook:
In #
5134151 Wangle used to not build, because something was using a futex. But that seems to have been rectified (or the build problems are hiding in headers that aren't used in the libfolly build).
I'll also update https://our.intern.facebook.com/intern/wiki/Folly/BuildingOnMac to point people to this script instead.
Test Plan:
Tested on my laptop which is running Yosemite (10.10.1)
Build, then inspect `otool -L .libs/*dylib`

Fix use of SSL session TransportInfo after txn is detached
Summary:
De-couple TransportInfo fields from SSL session structs to avoid
dangling pointers.
Facebook:
We sometimes lazily copy TransportInfo in handler after
detachClientTransaction for logging. If the socket is closed, then this
creates dangling pointers to some SSL structs. This is an attempt to fix
that.
This is similar to what @ajitb did in
https://phabricator.fb.com/
D1666951 which had to be abandoned because of
memory overhead. Here, instead of copying the relevant fields per
transaction, we are only doing it once per session (shared_ptr), so the
memory overhead should be negligible.
