Karl Wright commented on CONNECTORS-254:
----------------------------------------
I fooled around with curl and found the command we need. Here it is (assuming
hello.txt is a zero-length file):
curl --trace dump.out -location -F "id=123" -F "file=@hello.txt"
http://localhost:8983/solr/update/extract
The --trace option dumps a trace file which is essentially equivalent to
wireshark output. Good to know. Anyway, when I try this, I get the following
in Solr:

If this looks familiar, it's because we get the exact same trace when
multi-part form posting from ManifoldCF. So there is apparently a bug in Solr,
and there's no magic here.
My suggestion is that you follow up by creating a Solr ticket, trying to be
sure there isn't one already. I'll ping Simon and see if he knows anything.

> Project: ManifoldCF
> Issue Type: Bug
> Components: Lucene/SOLR connector
> Affects Versions: ManifoldCF 0.1, ManifoldCF 0.2, ManifoldCF 0.3
> Reporter: Shinichiro Abe
> Priority: Minor
> Fix For: ManifoldCF 0.3

>
> It seems that httpposter brings about bad request when posting 0 byte file.
> Solr log say the below. "missing content stream". Status code is 400.
> On the other hand when using Solr request handler without MCF, this exception
> is not thrown and the posting 0 byte files is indexed normally.
