Jason Gerlowski commented on SOLR-11675:
----------------------------------------
I did a little bit of digging into this recently.
The most relevant bit of code I could find is in the {{getApiInfo}} method of
{{V2HttpCall}}:
(https://github.com/apache/lucene-solr/blob/67a6a14302c159a46a5fc81e5e6e94643c288e99/solr/core/src/java/org/apache/solr/api/V2HttpCall.java#L200)
{code}
Api api = requestHandlers.v2lookup(path, method, parts);
if (api == null && path.endsWith(CommonParams.INTROSPECT)) {
// the particular http method does not have any ,
// just try if any other method has this path
api = requestHandlers.v2lookup(path, null, parts);
}
if (api == null) {
return getSubPathApi(requestHandlers, path, fullPath, new
CompositeApi(null));
}
...
{code}
The {{v2Lookup}} request returns null, as you would probably expect, but then a
non-null value is returned by {{getSubPathApi}}. {{getSubPathApi}} looked
loosely help/introspect related, but I don't know enough about the V2 API
framework to understand whether we want to be using the {{getSubPathApi}}
codepath here or not. Maybe I'm looking at the wrong chunk of code altogether.
Anyway, I plan to do some more digging on this soon. If I don't get to it,
hopefully this pointer is helpful.
