- BUILD: ssl: fix recent build breakage on older SSL libs
Since both DEVICEATLAS_INC and DEVICEATLAS_LIB are set to the same path
when building from sources, simply allow DEVICEATLAS_SRC to be set alone
to simplify the build procedure.
Till now 3 paths were needed, 51DEGREES_SRC, 51DEGREES_INC, and
51DEGREES_LIB. Let's make the last two default to 51DEGREES_SRC since
it's the same location, and fix the doc to reflect this (all three were
documented but inconsistently).
This diff is related to the additional documentation in
order to build the DeviceAtlas module and in addition with
an example of a basic configuration.
This library is designed to emit a zlib-compatible stream with no
memory usage and to favor resource savings over compression ratio.
While zlib requires 256 kB of RAM per compression context (and can only
support 4000 connections per GB of RAM), the stateless compression
offered by libslz does not need to retain buffers between subsequent
calls. In theory this slightly reduces the compression ratio but in
practice it does not have that much of an effect since the zlib
window is limited to 32kB.
Libslz is available at :
http://git.1wt.eu/web?p=libslz.git
It was designed for web compression and provides a lot of savings
over zlib in haproxy. Here are the preliminary results on a single
core of a core2-quad 3.0 GHz in 32-bit for only 300 concurrent
sessions visiting the home page of www.haproxy.org (76 kB) with
the default 16kB buffers :
BW In BW Out BW Saved Ratio memory VSZ/RSS
zlib 237 Mbps 92 Mbps 145 Mbps 2.58 84M / 69M
slz 733 Mbps 380 Mbps 353 Mbps 1.93 5.9M / 4.2M
So while the compression ratio is lower, the bandwidth savings are
much more important due to the significantly lower compression cost
which allows to consume even more data from the servers. In the
example above, zlib became the bottleneck at 24% of the output
bandwidth. Also the difference in memory usage is obvious.
More tests run on a single core of a core i5-3320M, with 500 concurrent
users and the default 16kB buffers :
At 100% CPU (no limit) :
BW In BW Out BW Saved Ratio memory VSZ/RSS hits/s
zlib 480 Mbps 188 Mbps 292 Mbps 2.55 130M / 101M 744
slz 1700 Mbps 810 Mbps 890 Mbps 2.10 23.7M / 9.7M 2382
At 85% CPU (limited) :
BW In BW Out BW Saved Ratio memory VSZ/RSS hits/s
zlib 1240 Mbps 976 Mbps 264 Mbps 1.27 130M / 100M 1738
slz 1600 Mbps 976 Mbps 624 Mbps 1.64 23.7M / 9.7M 2210
The most important benefit really happens when the CPU usage is
limited by "maxcompcpuusage" or the BW limited by "maxcomprate" :
in order to preserve resources, haproxy throttles the compression
ratio until usage is within limits. Since slz is much cheaper, the
average compression ratio is much higher and the input bandwidth
is quite higher for one Gbps output.
Other tests made with some reference files :
BW In BW Out BW Saved Ratio hits/s
daniels.html zlib 1320 Mbps 163 Mbps 1157 Mbps 8.10 1925
slz 3600 Mbps 580 Mbps 3020 Mbps 6.20 5300
tv.com/listing zlib 980 Mbps 124 Mbps 856 Mbps 7.90 310
slz 3300 Mbps 553 Mbps 2747 Mbps 5.97 1100
jquery.min.js zlib 430 Mbps 180 Mbps 250 Mbps 2.39 547
slz 1470 Mbps 764 Mbps 706 Mbps 1.92 1815
bootstrap.min.css zlib 790 Mbps 165 Mbps 625 Mbps 4.79 777
slz 2450 Mbps 650 Mbps 1800 Mbps 3.77 2400
So on top of saving a lot of memory, slz is constantly 2.5-3.5 times
faster than zlib and results in providing more savings for a fixed CPU
usage. For links smaller than 100 Mbps, zlib still provides a better
compression ratio, at the expense of a much higher CPU usage.
Larger input files provide slightly higher bandwidth for both libs, at
the expense of a bit more memory usage for zlib (it converges to 256kB
per connection).

Certain compilers running in virtualized environments may produce code
that the same processor cannot execute with -march=native, either because
of hypervisor bugs reporting wrong CPU features, or because of compiler
bugs forgetting to check CPU features. So better stop recommending this
combination so that users don't get trapped anymore.

git.1wt.eu is painfully slow and some people experience issues with
it. Better hide it and only advertise git.haproxy.org which is mirrored
on a faster server.
Also replace haproxy.1wt.eu with www.haproxy.org in the download URL
which appears in the stats page.
These makefiles were aging, with no support for SSL nor zlib, and
they were hard to maintain. GNU make is packaged and provided with
all systems which were relying on these makefiles, so better simply
delete them and enable the new features for everyone.

The "osx" target may now be passed in the TARGET variable. It supports
the same features as FreeBSD and allows its users to use the GNU makefile
instead of the platform-specific makefile which lacks some features.
This allows to build haproxy for unknown targets and still have poll().
If for any reason a target does not support it, just passing USE_POLL=""
disables it.

This commit introduces HTTP compression using the zlib library.
http_response_forward_body has been modified to call the compression
functions.
This feature includes 3 algorithms: identity, gzip and deflate:
* identity: this is mostly for debugging, and it was useful for
developping the compression feature. With Content-Length in input, it
is making each chunk with the data available in the current buffer.
With chunks in input, it is rechunking, the output chunks will be
bigger or smaller depending of the size of the input chunk and the
size of the buffer. Identity does not apply any change on data.
* gzip: same as identity, but applying a gzip compression. The data
are deflated using the Z_NO_FLUSH flag in zlib. When there is no more
data in the input buffer, it flushes the data in the output buffer
(Z_SYNC_FLUSH). At the end of data, when it receives the last chunk in
input, or when there is no more data to read, it writes the end of
data with Z_FINISH and the ending chunk.
* deflate: same as gzip, but with deflate algorithm and zlib format.
Note that this algorithm has ambiguous support on many browsers and
no support at all from recent ones. It is strongly recommended not
to use it for anything else than experimentation.
You can't choose the compression ratio at the moment, it will be set to
Z_BEST_SPEED (1), as tests have shown very little benefit in terms of
compression ration when going above for HTML contents, at the cost of
a massive CPU impact.
Compression will be activated depending of the Accept-Encoding request
header. With identity, it does not take care of that header.
To build HAProxy with zlib support, use USE_ZLIB=1 in the make
parameters.

Hank A. Paulson suggested to add CPU=native to optimize the code for
the build machine. This makes sense in a lot of situations. Since it
is often possible to have both 32 and 64 bits supported on recent
systems, the ARCH=32 and ARCH=64 build options were also added.
Patrick Mézard reported that it was a bit awkward to have the CONTRIB
and contrib entries in the source archive since those can conflict on
case-insensitive file systems. That made a good opportunity to refresh
the README file and to remove that old outdated file.
After considering various possibilities, we compiled haproxy under cygwin.
Attached is an updated full diff that also has the TARGET=cygwin documented.
The whole thing compiles and installs with this diff only.
In cygwin 1.7 (now in beta), there is apparently support for ipv6. Cygwin
1.5 (later versions, anyway) already includes some support in the form of a
define USE_IPV6. When defined, it declares the sockaddr_in6 struct and
possibly other things. The above definition AF_INET6=23 is taken from
their /usr/include/socket.h file (where it is #if 0'd out).
We are running into a socket limit. It appears that Cygwin (running on
Windows 2003 Server) will only allow us to set ulimit -n (maximum open
files) to 3200, which means we're a little short of 1600 connections.
The limit of 3200 is an internal Cygwin limit. Perhaps they can raise it in
the future. Using the nbproc option, I was able to bring up 10 servers. It
seems to me that they were able to handle over 2000 connections (even though
each had maxconn 1500 set, and the hard Cygwin fd limit).
When trying to build a 32-bit binary on a 64-bit platform, we generally
need to pass "-m32" to gcc, which is not convenient with current makefile.
Note that this option requires gcc >= 3.
In order to ease parameter passing, a new ARCH= makefile option has been
added. If it receives a target architecture, according "-m32"/"-m64" and
"-march=xxxx" will be passed to gcc. Only the generic makefile has been
changed to support this option right now as the need only appeared on Linux.
The spec file now makes use of this option so that rpmbuild can automatically
build with the proper architecture.
