Thanks! It's a good tool. By now, haclient doesn't generate a xml file.
Ideally, haclient should generate a valid xml, and then transfer to
mgmtd. Xinwei and I think that the current protocol is too complicated
and has many limitations. We want to simplify the protocol and improve
the applicability so that it's convenient to implement full features
according to the dtd.
Right; the client very likely should directly talk to the CIB daemon.
(Which already supports this; we may need a way to apply ACLs in the
future though.)
You're preaching to the choir ;-)
I have extended the metadata to explicitly include enumeration values.
I think this would help a lot for the kinds of validations I think
you're doing.
In my implementation,I've adopted the enumeration values specified in
the dtd to be used for the list of combobox options.
It is quite possible that a DTD is not powerful enough to adequately
describe the syntax and semantics of the CIB. The DTD is, simply put,
the oldest and least complex schema format for XML, and happened to be
what I knew when I conjured up the original one ;-)
XML Schema, Relax NG (or others I know even less about) may be more
appropriate standards to describe the CIB as we have it today, and as it
evolves further.
This may be preferable to needing to duplicate this in home-grown
fashion. A lint-like tool is still a good idea, but it should be build
on top of this, IMHO.
/me redirects this whining into /dev/null
Feel free to investigate the best tools, define the DTD-replacement, and
get Andrew to adopt it - incorporating it into crm_verify. "Show me the
code" is the Linux way after all...
If it has python support, likely all I'll have to do to use it is import
a few more python classes at the top, and add a half-dozen lines to
ciblint to read in the DTD-replacement, and call its validation function.
When all is said and done, it won't eliminate more than a few hundred
lines of code in ciblint (which is now more than 2K lines and still
growing).
