From c50524efd523e885f370374e33cd5d5549ed9079 Mon Sep 17 00:00:00 2001 From: Sebastian Spaeth Date: Sun, 16 May 2010 15:56:27 -0700 Subject: [PATCH] python: have docs reflect current return value behavior Database.find_message() used to be able to reliably indicate whether a message exists or not (in which case it returns None). However, the recent API change of the notmuch library means we will return None even for all Xapian exceptions, which happens e.g. when the current Database has been modified by another project. Therefore the return value of None cannot be reliably be used to indicate whether a message exists or not. Make the docs state that explicitely.
