Hi!
I'm trying to access a readonly database without locks, using the
amalgamation of SQLite 3.6.14.2
After I opened the database with flags = SQLITE_OPEN_READONLY I perform
sqlite3_exec (db, "PRAGMA omit_readlock=ON", 0, 0, 0);
I traced that down into the amalgamation to the point where the database
flag is set in flagPragma...
db->flags |= p-mask;
So I can be sure the pragma syntax is correct.
Now when I execute a SELECT statement, it is parsed and I run into
pagerSharedLock, but
the pager->noReadlock variable is 0. As a result the database file gets
locked.
It look like the initialization of the pager->noReadlock flag, but that
happens when the database is
opened.
Am I doing something wrong or did this ("Very experimental") feature got
lost in past refactorings?
Thanks for listening & in advance to any hints
Joerg
