Cool.  It turns out I didn't have to make it all backwards incompatible just 
yet, because instead I just detect if it's using the old Chert backend and 
force a reindex of all email to upgrade to Glass.

(but can still read from a mix of both, so you can phase the upgrade)

This is going to the rest of FastMail production today after running happily 
for the past 4 days for ~5% of our users.

Xapian search databases

2016-11-02 Thread Bron Gondwana via Info-cyrus 
Just out of interest - is anyone other than Fastmail currently using the Cyrus 
Xapian-based search system?

We're making a bunch of changes:
* transition to Glass backend in Xapian 1.4
* move cyrus.indexed information into Xapian metadata
* index by GUID rather than folder/uid pair

These changes aren't entirely backwards compatible, so we'll have to do a 
conversion process at FastMail - but keeping code in upstream Cyrus to do the 
conversion will make everything more complex and brittle forever, so I'd like 
to throw it away ASAP.

Obviously if there are other sites which are running Xapian already, then 
you'll have to go through the same pain, so I'd try to make it all more generic!

Bron.
