# Updating schema files #
## Experimental features ##
Experimental features go into `${base}-next.rng`
Create from the most recent `${base}-${X}.${Y}.rng` if it does not already exist
## Stable features ##
The current stable version is determined from the `known_schemas` array in `lib/common/xml.c`.
It will be the entry prior to `pacemaker-next` and has the form `pacemaker-${X}.${Y}`.
### Simple Additions
When the new syntax is a simple addition to the previous one, create a new entry with `${Y} = ${Yold} + 1`
### Feature Removal or otherwise Incompatible Changes
When the new syntax is not a simple addition to the previous one, create a new entry with `${X} = ${Xold} + 1` and `${Y} = 0`.
An XSLT file is also required that converts an old syntax to the new one.
See `xml/upgrade06.xsl` for an example.
### General Proceedure
1. Copy the most recent version of `${base}-*.rng` to `${base}-${X}.${Y}.rng`
1. Commit the copy, eg. `"Clone the latest ${base} schema in preparation for changes"`.
This way the actual change will be included with the creation of the new schema.
1. Modify `${base}-${X}.${Y}.rng` as required
-1. Add the new `${X}.${Y}` to `RNG_versions` in `xml/Makefile.am`
1. Add an XSLT file if required and update `xslt_SCRIPTS` in `xml/Makefile.am`
1. Update `known_schemas` in `lib/common/xml.c`, add it prior to the entry for `pacemaker-next`.
The second last field of the previous entry needs to be set to `0`.
For example:
/* 6 */ { 2, "pacemaker-1.2", NULL, NULL, -1, NULL },
/* - */ { 2, "pacemaker-next", NULL, NULL, -1, NULL }, /* Feature playground */
becomes:
/* 6 */ { 2, "pacemaker-1.2", NULL, NULL, 0, NULL },
/* 7 */ { 2, "pacemaker-1.3", NULL, NULL, -1, NULL },
/* - */ { 2, "pacemaker-next", NULL, NULL, -1, NULL }, /* Feature playground */
or for an incompatible change:
/* 6 */ { 2, "pacemaker-1.2", NULL, "upgrade12.xsl", 0, NULL },
/* 7 */ { 2, "pacemaker-2.0", NULL, NULL, -1, NULL },
/* - */ { 2, "pacemaker-next", NULL, NULL, -1, NULL }, /* Feature playground */
See https://github.com/beekhof/pacemaker/commit/041ba95 and its parent commit for an example.
1. Commit
## Admin Tasks
New features will not be available until the admin
1. Updates all the nodes
1. Runs the equivalent of `cibadmin --upgrade`
