I'm not sure if i agree with that statement .. i would think that figuring
out the "model" or how updates should be handled in a generic way, what
all of the "Plugin" types are, and what their APIs should be is the most
important issue -- once we have those issues settled we could allways
write a new "SolrServlet2" that made the URL structure work anyway we
want.

I hate to inundate you with more code, but it seems like the best way
to describe a possible interface.
//-----------------------------------------------
interface ContentStream
{
String getName();
String getContentType();
InputStream getStream();
}
interface SolrParams
{
String getParam( String name );
String[] getParams( String name );
}
//-----------------------------
interface SolrRequest
{
SolrParams getParams();
ContentStream[] getContentStreams(); // Iterator?
long getStartTime();
}
interface SolrResponse
{
int getStatus(); // ???
NamedList getProps(); // ???
}
//-----------------------------
interface SolrRequestProcessor
{
SolrResponse process( SolrRequest req );
SolrResponseWriter getWriter( SolrRequest req ); // default
}
interface SolrResponseWriter
{
void write(Writer writer, SolrRequest request, SolrResponse response);
String getContentType(SolrRequest request, SolrResponse response);
}
//-----------------------------
Then a servlet (or filter) could be in charge of parsing URL/params
into a request. It would pick a Processor and send the output to a
writer. If someone wanted a custom URL scheme, they would overide the
servlet/filter.
Perhaps SolrRequest should have an object for solrCore. It would be
better if it does not need to go to the static
SolrCore.getUpdateHandler().
I am proposing ContentStream[] getContentStreams() because it would be
simpler then an iterator. In the case of multipart upload, if you
offered an API closer to:
http://jakarta.apache.org/commons/fileupload/streaming.html
You would not have any parameters until after you read each Item and
convert the form fields to parameters.
Thoughts?
