[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.

[MINOR] move MAXPATHLEN definition to compat.h MAXPATHLEN may be used at other places, it's unconvenient to have it redefined in a few files. Also, since checking it requires including sys/param.h, some versions of it cause a macro declaration conflict with MIN/MAX which are defined in tools.h. The solution consists in including sys/param.h in both files so that we ensure it's loaded before the macros are defined and MAXPATHLEN is checked.

[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.

[MEDIUM] remove TCP_CORK and make use of MSG_MORE instead send() supports the MSG_MORE flag on Linux, which does the same as TCP_CORK except that we don't have to remove TCP_NODELAY before and we don't need any syscall to set/remove it. This can save up to 4 syscalls around a send() (two for setting it, two for removing it), and it's much cleaner since it is not persistent. So make use of it instead.

OPTIM/MINOR: make it possible to change pipe size (tune.pipesize) By default, pipes are the default size for the system. But sometimes when using TCP splicing, it can improve performance to increase pipe sizes, especially if it is suspected that pipes are not filled and that many calls to splice() are performed. This has an impact on the kernel's memory footprint, so this must not be changed if impacts are not understood.

[MINOR] add transparent proxy support for balabit's Tproxy v4 Balabit's TPROXY version 4 which replaces CTTPROXY provides a similar API to the previous proxy, but relies on IP_FREEBIND instead of IP_TRANSPARENT. Let's add it.

/* On Linux, IP_TRANSPARENT and/or IP_FREEBIND generally require a kernel patch */
[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.
