Hi List,
I've configured haproxy with htx and when i try to filter the stats
webpage.
Sending this request: "GET /?;csv;scope=b1" to '2.0-dev0-762475e
2019/01/10' it will crash with the trace below.
1.9.0 and 1.9.1 are also affected.
Can someone take a look? Thanks in advance.
A regtest is attached that reproduces the behavior, and which i think
could be included into the haproxy repository.
Pieter,
Here is the patch that should fix this issue. This was "just" an
oversight when the stats applet has been adapted to support the HTX.
If it's ok for you, I'll also merge your regtest.
Thanks
It seems the patch did not change/fix the crash.? Below looks pretty
much the same as previously. Did i fail to apply the patch properly.? It
seems to have 'applied' properly checking a few lines of the touched
code manually. As for the regtest, yes please merge that if its okay
as-is, perhaps after the fix is also ready :).
Regards,
PiBa-NL (Pieter)
