int update_validation ( xmlNode **  xml_blob,
int *  best,
int  max,
gboolean  transform,
gboolean  to_logs 
)

Update CIB XML to most recent schema version.

"Update" means either actively employ XSLT-based transformation(s) (if intermediate product to transform valid per its declared schema version, transformation available, proceeded successfully with a result valid per expectated newer schema version), or just try to bump the marked validating schema until all gradually rising schema versions attested or the first such attempt subsequently fails to validate. Which of the two styles will be used depends on transform parameter (positive/negative, respectively).

Parameters
[in,out]xml_blobXML tree representing CIB, may be swapped with an "updated" one
[out]bestThe highest configuration version (per its index in the global schemas table) it was possible to reach during the update steps while ensuring the validity of the result; if no validation success was observed against possibly multiple schemas, the value is less or equal the result of get_schema_version applied on the input xml_blob value (unless that function maps it to -1, then 0 would be used instead)
[in]maxWhen transform is positive, this allows to set upper boundary schema (per its index in the global schemas table) beyond which it's forbidden to update by the means of XSLT transformation
[in]transformWhether to employ XSLT-based transformation so as to allow overcoming possible incompatibilities between major schema versions (see above)
[in]to_logsIf true, output notable progress info to internal log streams; if false, to stderr
Returns
pcmk_ok if no non-recoverable error encountered (up to caller to evaluate if the update satisfies the requirements per returned best value), negative value carrying the reason otherwise
