I know this is a old haproxy version but I have not the option to update as it's
part of a vendor product.
I need to bring the `[haproxy-2.0.git]/ contrib/spoa_server/` up and runnig or
`[haproxy-1.8.git]/contrib/spoa_example/` from 1.8.4 to be able to run a python
script.
Any help is welcome and I can offer some money for the help. It's urgent so I
will need the help asap.
You can contact me also off the list.
Hi Aleks,
The spoa_example cannot run python script. But I take a look to the spoa_server
and it seems to usable with HAProxy 1.8 with a small patch. You must downgrade
the SPOE version and change the encoding of the frame's flags. The example
configuration must also be adapted because there is no debug converter in
HAProxy 1.8.
But, as you said, HAProxy 1.8.4 is old, and many fixes was pushed on the SPOE
since then. So you would experience some bugs. Be careful.
And I noticed a bug with the spoe_server, It seems to accept and process only
one connection per worker because of a while loop to read frames. I'm cc'ing
Thierry.
I attached a quick-and-dirty patch to downgrade SPOP version of the spoa_server
to 1.0.
