Xapian discuss - Jan 2008 - how to catch Xapian::DatabaseModifiedError in perl?

Hello,

The pod-documentation of Database.pm says:

I really would like to do that, but as soon as this exception occures  
my applications dies with a SIGABRT.

Is there any posibility to catch a Xapian::DatabaseModifiedError with  
Search::Xapian in Perl?

At the moment I need reopen() the database before each query, which  
seems the only way to handle concurrent reading and updating in with  
perl, but it feels not very neat.

Regards,
mrks

I have the same issue, and have started creating a patch for  
Search::Xapian in bug #230[1].

This bug is meant to be for the maintainer to use before releasing the  
packages, as it generates the code from xapian-core exceptions, rather  
than hardcode each exception in the bindings. I run a patched version  
of 1.0.4 in production and catch Search::Xapian::DatabaseModifiedError  
succesfully there with the exception-classes and patched Enquire.xs.
