Ok. It seems that it's unrelated to virtual at all. It's enough to just
use any folder from non-inbox private namespace and perform FTS multiple
I've added a few debug prints around fts_lucene_settings_checksum,
fts_index_have_compatible_settings and fts_index_set_header and fount
that fts_lucene_settings_checksum is always same.
The root issue is that fts_lucene_settings_checksum reads checksum from
mailbox with empty name (probably namespace root mbox). At the same time
fts_index_set_header is called for all mailboxes in namespace except this
That's actually why I'm always getting 'Settings have changed' warning.
I've tried to create 'archive' mailbox (same as namespace name) and got
call to fts_index_set_header() for it during scan, but with zero
Any suggestions how to fix it?
