[BIGMOVE] exploded the monolithic haproxy.c file into multiple files. The files are now stored under : - include/haproxy for the generic includes - include/types.h for the structures needed within prototypes - include/proto.h for function prototypes and inline functions - src/*.c for the C files Most include files are now covered by LGPL. A last move still needs to be done to put inline functions under GPL and not LGPL. Version has been set to 1.3.0 in the code but some control still needs to be done before releasing.

Operating system compatibility interface.
[MEDIUM] support fully transparent proxy on Linux (USE_LINUX_TPROXY) Using some Linux kernel patches, it is possible to redirect non-local traffic to local sockets when IP forwarding is enabled. In order to enable this option, we introduce the "transparent" option keyword on the "bind" command line. It will make the socket reachable by remote sources even if the destination address does not belong to the machine.

#include <sys/socket.h>
[BUILD] fix 2 minor issues on AIX AIX does not know about MSG_DONTWAIT. Fortunately, nearly all sockets are already set to O_NONBLOCK, so it's not even required to change the code. It was only necessary to add this fcntl to the log socket which lacked it. The MSG_DONTWAIT value has been defined to zero when unset in order to make the code cleaner and more portable. Also, on AIX, "hz" is defined, which causes a problem with one function parameter in time.c. It's enough to rename the parameter there. Last, fix a missing #include <string.h> in proxy.c.

[BUILD] fix build with gcc 4.3 For Fedora 9 gcc 4.3 will be shipping as a feature, and right now haproxy does not compile with gcc 4.3. It appears that there is a reordering of headers or something along those lines, This is the patch that gets haproxy to compile with gcc 4.3. I'm not sure if this is the correct approach you would want to use, so please correct me. If this works for you, I'll go ahead and put this patch in the src rpm until a release of haproxy which compiles with gcc 4.3 is released.

[CLEANUP] remove dependency on obsolete INTBITS macro The INTBITS macro was found to be already defined on some platforms, and to equal 32 (while INTBITS was 5 here). Due to pure luck, there was no declaration conflict, but it's nonetheless a problem to fix. Looking at the code showed that this macro was only used for left shifts and nothing else anymore. So the replacement is obvious. The new macro, BITS_PER_INT is more obviously correct.

This patch adds a workaround to this problem by figuring out the value for the one used by SO_REUSEADDR.
