X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;p=thirdparty%2Fsqlite.git

When reading a super-journal name from a journal file, allocate a new buffer rather than using Pager.pTmpSpace. This prevents a buffer overrun that could occur when using a VFS with a large sqlite3_vfs.mxPathname value with a database with a small page size.
