get_document() on an empty database raises floating point exception

[Richard Boulton]

By empty, I mean a Database object uninitialised with any concrete databases.

Example code in python:

import xapian
db=xapian.Database()
db.get_document (1)

I would expect a DocNotFound exception.

This is because we don't check internal.size() and then proceed to divide and modulus by 0.

In fact many methods of Xapian::Database currently fail to check this...

We should fix this before 1.1.4 - it's not showstopper bug, but it's easy to fix and low risk.

[Olly Betts]

Fixed for all methods of Database in trunk r13668 (and noted ticket number in r13669).

Marking for backporting to 1.0.18.

Backported in r13679.
