Hi! I purposely put a MODIFY of system tables in epp file without considering dbb->readOnly() flag.
And it worked (changed the database) and committed the change. Shouldn't that be prevent in lower layers? Then I chmod -w the database. Then it fails at commit time with: Statement failed, SQLSTATE = 08001 I/O error during "write" operation for file "/home/asfernandes/fb/dev/trunk.git/z.fdb" -Error while trying to write to file -Bad file descriptor Adriano ------------------------------------------------------------------------------ Firebird-Devel mailing list, web interface at https://lists.sourceforge.net/lists/listinfo/firebird-devel
