Recent commit 83614a9fb ("MINOR: httpclient: initialize the proxy") broke
reg tests that match the output of "show stats" or "show servers state"
because it changed the proxies' numeric ID.
In fact it did nothing wrong, it just registers a proxy and adds it at
the head of the list. But the automatic numbering scheme, which was made
to make sure that temporarily disabled proxies in the config keep their
ID instead of shifting all others, sees one more proxy and increments
next_pxid for all subsequent proxies.
This patch avoids this by not assigning automatic IDs to such internal
proxies, leaving them with their ID of -1, and by not shifting next_pxid
for them. This is important because the user might experience them
appearing or disappearing depending on apparently unrelated config
options or build options, and this must not cause visible proxy IDs
to change (e.g. stats or minitoring may break).
Though the issue has always been there, it only became a problem with
the recent proxy additions so there is no need to backport this.
The HAProxy documentation has been split into a number of different files for ease of use. Please refer to the following files depending on what you're looking for : - INSTALL for instructions on how to build and install HAProxy - BRANCHES to understand the project's life cycle and what version to use - LICENSE for the project's license - CONTRIBUTING for the process to follow to submit contributions The more detailed documentation is located into the doc/ directory : - doc/intro.txt for a quick introduction on HAProxy - doc/configuration.txt for the configuration's reference manual - doc/lua.txt for the Lua's reference manual - doc/SPOE.txt for how to use the SPOE engine - doc/network-namespaces.txt for how to use network namespaces under Linux - doc/management.txt for the management guide - doc/regression-testing.txt for how to use the regression testing suite - doc/peers.txt for the peers protocol reference - doc/coding-style.txt for how to adopt HAProxy's coding style - doc/internals for developer-specific documentation (not all up to date)
