Now that SLZ is merged, let's update the makefile and compression
files to use it. As a result, SLZ_INC and SLZ_LIB are neither defined
nor used anymore.
USE_SLZ is enabled by default ("USE_SLZ=default") and can be disabled
by passing "USE_SLZ=" or by enabling USE_ZLIB=1.
The doc was updated to reflect the changes.
Solaris 9 (released 2002) added support for closefrom().
I bumped the version in the comment to 10 as the default feature
flags already has event ports enabled which were introduced in
Solaris 10.
Other users are using musl, namely on Docker. It builds fine with
linux-glibc-legacy but not linux-glibc, which needs to first disable
USE_BACKTRACE. Better add a valid entry for it instead of hacking
around another libc.
As haproxy wont build on AIX 7.2 using the old "aix52" TARGET a new
TARGET was introduced which adds two special CFLAGS to prevent the
loading of AIXs xmem.h and var.h. This is done by defining the
corresponding include-guards _H_XMEM and _H_VAR. Without excluding
those headers-files the build fails because of redefinition errors:

Futhermore, to enable multithreading via USE_THREAD, the atomic
library was added to the LDFLAGS. Finally, two new CPUs were added
to simplify the usage of power8 and power9 optimizations.
This TARGET was only tested on GCC 8.3 and may or may not work on
IBM's native C-compiler (XLC).
Should be backported to 2.1.
These are some errors met when trying to build with gcc 3.4 on an
old (13 years-old) Solaris 10 and on an even older Linux 2.4 with
glibc 2.2.5. A few options were enough to fix the build there.
The INSTALL guide, the Lua doc and the Prometheus exporter's README all
used to reference "linux2628", "linux26" or even "linux". These were all
updated to consistently reflect "linux-glibc" instead. The default options
were updated there as well so that it should build cleanly on most distros.
dlmalloc has remained unused for quite a while now, in part because it
is not thread-safe and in part because it has been superseded by the
much better and faster jemalloc. So let's simplify the makefile and
remove entries related to this library.
Since the "wurfl" device detection engine was merged slightly more than
two years ago (2016-11-04), it never received a single fix nor update.
For almost two years it didn't receive even the minimal review or changes
needed to be compatible with threads, and it's remained build-broken for
about the last 9 months, consecutive to the last buffer API changes,
without anyone ever noticing! When asked on the list, nobody confirmed
using it :
https://www.mail-archive.com/haproxy@formilux.org/msg32516.html
And obviously nobody even cared to verify that it did still build. So we
are left with this broken code with no user and no maintainer. It might
even suffer from remotely exploitable vulnerabilities without anyone
being able to check if it presents any risk. It's a pain to update each
time there is an API change because it doesn't build as it depends on
external libraries that are not publicly accessible, leading to careful
blind changes. It slows down the whole project. This situation is not
acceptable at all.
It's time to cure the problem where it is. This patch removes all this
dead, non-buildable, non-working code. If anyone ever decides to use it,
which I seriously doubt based on history, it could be reintegrated, but
this time the following guarantees will be required :
- someone has to step up as a maintainer and have his name listed in
the MAINTAINERS file (I should have been more careful last time).
This person will take the sole blame for all issues and will be
responsible for fixing the bugs and incompatibilities affecting
this code, and for making it evolve to follow regular internal API
updates.
- support building on a standard distro with automated tools (i.e. no
more "click on this site, register your e-mail and download an
archive then figure how to place this into your build system").
Dummy libs are OK though as long as they allow the mainline code to
build and start.
- multi-threaded support must be fixed. I mean seriously, not worked
around with a check saying "please disable threads, we've been busy
fishing for the last two years".
This may be backported to 1.9 given that the code has never worked there
either, thus at least we're certain nobody will miss it.

The README was barely usable after all the additions having accumulated
over the years. This patch introduces a new INSTALL file explaining how
to build and install haproxy with various levels of details. The README
is now mostly an index to the list of useful documentations.
