Subject: REGTESTS: test track support for dynamic servers
X-Git-Tag: v2.5-dev2~17
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=79c52ec6b437b35be141f8c2d20d67742be2a729;p=thirdparty%2Fhaproxy.git

REGTESTS: test track support for dynamic servers

Create a regtest for the 'track' keyword support by dynamic servers.

First checks are executed to ensure that tracking cannot be activated on
non-check server or dynamic servers.

Then, 3 scenarii are written to ensure that the deletion of a dynamic
server with track is properly handled and other servers in the track
chain are properly maintained.
