smart_malloc hphp/vector/zend_array

New smart_malloc/free api for variable-size smart-allocation.  Memory
allocated with smart_malloc can be freed with smart_free, but otherwise
is swept at request-end.  Allocations underl0 1K are bump-allocated from
slabs with an 8-byte header.  Over 1K are routed to malloc with a
16-byte header (doubly-linked list).

ZendArray, VectorArray, HphpArray refactored to use smart_malloc instead
of a bunch of storage-segregated size classes.

HipHop for PHP

HipHop is a high performance PHP toolchain. Currently supported platforms are Linux and FreeBSD. There is no OS X support.

Required Packages

The latest information is available on the wiki

  • cmake 2.6 is the minimum version
  • g++/gcc 4.3 is the minimum version
  • Boost 1.37 is the minimum version
  • flex
  • bison
  • re2c
  • libmysql
  • libxml2
  • libmcrypt
  • libicu 4.2 is the minimum version
  • openssl
  • binutils
  • libcap
  • gd
  • zlib
  • tbb Intel's Thread Building Blocks
  • Oniguruma
  • libpcre
  • libexpat
  • libmemcached

The following packages have had slight modifications added to them. Patches are provided and should be made against the current source copies.

  • libcurl
  • src/third_party/libcurl.fb-changes.diff
  • libevent 1.4
  • src/third_party/libevent-1.4.13.fb-changes.diff OR src/third_party/libevent-1.4.14.fb-changes.diff


You may need to point CMake to the location of your custom libcurl and libevent, or to any other libraries which needed to be installed. The CMAKE_PREFIX_PATH variable is used to hint to the location.

export CMAKE_PREFIX_PATH=/home/user

To build HipHop, use the following:


cd /home/user/dev
git clone git://
cd hiphop-php
git submodule init
git submodule update
export HPHP_HOME=`pwd`
export HPHP_LIB=`pwd`/bin
cmake .

If you are using FreeBSD instead use export - setenv

Once this is done you can generate the build file. This will return you to the shell. Finally, to build, run make. If any errors occur, it may be required to remove the CMakeCache.txt directory in the checkout.
