added "wt_hash" which shows only 60 collisions in 575k values, which
sets it between hashword() and djbx33(). It's also between both in
terms of performance, but the most important part is that its variable
length rotation mechanism should make it really harder to predict and
attack than the other ones.
Compare the results of recv/send with the parameter passed and
detect whether the system has no free buffer space for send()
or has no data anymore for recv(). This dramatically reduces
the number of syscalls (by about 23%).
Aleksandar Lazic has collected many hashing algorithms and put them
in one file to ease benchmarking. Some algos look promising, some
of them have been checked further with uri_hash. Some results on
various systems/hardware are stored in hash_results.txt.
The uri_hash.c program makes it very easy to benchmark the
distribution of hash algos. Pass it one word per line, and
it will show the distribution per server for 1 to 10 servers.
* fixed a stupid bug introduced in 1.1.22 which caused second and subsequent
'default' sections to keep previous parameters, and not initialize logs
correctly.
* fixed a second stupid bug introduced in 1.1.22 which caused configurations
relying on 'dispatch' mode to segfault at the first connection.
* 'option httpchk' now supports method, HTTP version and a few headers.
* now, 'option httpchk', 'cookie' and 'capture' can be specified in
'defaults' section
* a fresh new english documentation
* large Makefile cleanup for increased portability
* new build script 'build.cfg' for Formilux-0.1.8
* new startup script 'init.haproxy.flx0' for Formilux-0.1.8
* 'listen' now supports optionnal address:port-range lists
* 'bind' introduced to add new listen addresses
* fixed a bug which caused a session to be kept established on a server till
it timed out if the client closed during the DATA phase.
* the port part of each server address can now be empty to make the proxy
connect to the server on the same port it was connected to, be an absolute
unsigned number to reflect a single port (as in older versions), or an
explicitly signed number (+N/-N) to indicate that this offset must be
applied to the port the proxy was connected to, when connecting to the
server.
* the 'port' server option allows the user to specify a different
health-check port than the service one. It is mandatory when only relative
ports have been specified and check is required. By default, the checks are
sent to the service port.
* new 'defaults' section which is rather similar to 'listen' except that all
values are only used as default values for future 'listen' sections, until
a new 'defaults' resets them. At the moment, server options, regexes,
cookie names and captures cannot be set in the 'defaults' section.
* Makefile now optimizes for Ultrasparc by default on Solaris/Sparc
* large documentation updates and fixes
* new 'tests' directory with some debug files
