This option had always been broken in HTX, which means that the first
breakage appeared in 1.9, that it was broken by default in 2.0 and that
no workaround existed starting with 2.1. The way this option works is
praticularly unfit to the rest of the configuration and to the internal
architecture. It had some uses when it was introduced 14 years ago but
nowadays it's possible to do much better and more reliable using a
set of "http-request set-dst" and "http-request set-uri" rules, which
additionally are compatible with DNS resolution (via do-resolve) and
are not exclusive to normal load balancing. The "option-http_proxy"
example config file was updated to reflect this.
The option is still parsed so that an error message gives hints about
what to look for.
This one was deprecated in 2.3 and marked for removal in 2.5. It suffers
too many limitations compared to threads, and prevents some improvements
from being engaged. Instead of a bypassable startup error, there is now
a hard error.
The parsing code was removed, and very few obvious cases were as well.
The code is deeply rooted at certain places (e.g. "for" loops iterating
from 0 to nbproc) so it will not be that trivial to remove everywhere.
The "bind" and "bind-process" parsers will have to be adjusted, though
maybe not completely changed if we later want to support thread groups
for large NUMA machines. Some stats socket restrictions were removed,
and the doc was updated according to what was done. A few places in the
doc still refer to nbproc and will have to be revisited. The master-worker
code also refers to the process number to distinguish between master and
workers and will have to be carefully adjusted. The MAX_PROCS macro was
reset to 1, this will at least reduce the size of some remaining arrays.
Two regtests were dependieng on this directive, one with an explicit
"nbproc 1" and another one testing the master's CLI using nbproc 4.
Both were adapted.
Hello,
You will find attached an updated release of previously submitted patch.
It polish some part and extend ACL engine to match IP and PORT parsed in
HTTP request. (and take care of comments made by Willy ! ;))
Best regards,
