couchdb-mango git commit: Handle malformed manual design docs.

Repository: couchdb-mango
Updated Branches:
  refs/heads/2816-malformed-docs [created] 2d26f2295


Handle malformed manual design docs.

We separate index validation into three phases. The first phase is
index creation via our _index api. This validation piece will throw
an error for invalid index definitions. The second phase is during
the indexing of documents. If an index definition is not valid, we
will not use the definition to index documents. We silently log the
error. Finally, during the query phase, design documents are again
validated to ensure correct indexes are used. Again, we log an error
but silently ignore invalid index definitions. Our validation will
integrate into a consolidated validation of all indexers.
