Resolved Problems

  • sqlite_open() crash - There is a condition when the sqlite_open() function causes a server process to crash when called from a folder that has an unreadable ancestor folder ( -- A patch has been applied to fix this.

  • sqlite_query() crash - There is a condition when a malformed SQL query is missing a "from table" clause that causes a server process to crash ( -- This patch has been backported and applied.
