There are times when you want multiple singletons of the same

Singleton<Foo> object to get to the underlying singleton.  This is most
useful in cases where a singleton is used inside of the same cpp file it
is defined.

Finally, make get() faster by caching the underlying pointer rather than
accessing the shared pointer.  If you're using it, you already have a

10 years agoFix block overhead estimation in tests
Nicholas Ormrod [Fri, 22 Aug 2014 17:07:25 +0000 (10:07 -0700)]
Fix block overhead estimation in tests

Summary:
folly/test/ArenaTest.h assumes that goodMallocSize will account
for the block overhead, if the size is +1. However, when compiling
without jemalloc (as, I would imagine, most of our open-source clients
do), goodMallocSize(64 + 1) returns 65, which is less than 64 +
sizeof(Block), and so the tests fail.

I have added a constant to Arena.h which exposes the overhead taken by
the Block, and changed the tests to use that value instead of 1.
(Arena::getTotalSize relies on the totalAllocatedSize_ variable, which
is only non-trivially set in allocateSlow, where the size of the heap is
added to sizeof(Block)).

10 years agofbcode: __x__-protect all __attribute__ keywords, mechanically
Jim Meyering [Sun, 17 Aug 2014 21:34:32 +0000 (14:34 -0700)]
fbcode: __x__-protect all __attribute__ keywords, mechanically

Summary:
The first (and sometimes 2nd) argument to __attribute__
should begin and end with "__". If it does not, then it
is at risk of conflicting with user cpp-defined symbols.
Don't do that.  This change mechanically corrects most
such violations in fbcode.  A companion change (see parent task)
adds a lint rule to help keep things clean going forwards.

Define this function to filter the list of file names to which
we will apply the transformations. First, ensure we modify only
C and C++ sources.  The second process excludes a few directories
that appear to contain third-party code:

filter() {
grep -E '\.(c|h|cc|cpp|hpp)$' | grep -vE \
'^external/|/unbound/|/gearmand_|(3rd|third.)party|/external/libevent'
}

then, run this command,

git grep -l __attribute__ | filter \
| xargs perl -pi -e 's/(__attribute__ *)\(\(( *[^_]\w+)/$1((__${2}__/g'

inducing changes like this, for each such keyword:

-} __attribute__((packed));
+} __attribute__((__packed__));

That got all but the __format__ archetype arguments like this:
__attribute__((__format__(printf.  That final "printf"
keyword should have the "__" prefix and suffix, too.

Run this command to transform those remaining uses:

git grep -l '__attribute__.*__format' | filter | xargs perl -pi -e \
's/(__attribute__ *\(\(__format__ *)\( *(printf|scanf|strftime|strfmon)/$1(__${2}__/g'

That command induces changes like this:

-static inline int __attribute__ ((__format__ (printf, 3, 4)))
+static inline int __attribute__ ((__format__ (__printf__, 3, 4)))

This exercise is useful to avoid spurious name-space conflicts,
especially when the unprotected keyword is used in a header file.

Test Plan:
I've ensured tao builds and passes its tests.
I will watch the arc-run tests.
