#152 closed defect (released)

Document IDs can overflow, and produce a document with an ID of 0.

Description

Daniel Ménard noted in an email to xapian-devel (at ​http://permalink.gmane.org/gmane.comp.search.xapian.devel/1192) that if you set lastdocid to "-1" (by calling replace_document() with that ID), the next document will be added with a docid of 0.

We should detect this error (probably by comparing the allocated docid to 0) and report an error in this case. The error should suggest a way out of the situation (which is probably to run copydatabase to reallocate docids).
