  Portability fix
mysql-test/t/create.test:
  Portability fix

+This file should contain all know fatal bugs in the Maria storage
+engine for the last source or binary release.  Minor bugs, extensions
+and feature request and bugs found since this release can be find in the
+MySQL bugs databases at: http://bugs.mysql.com/
+
+There shouldn't normally be any bugs that affects normal operations in
+any Maria release.  Still, there are always exceptions and edge cases
+and that's what this file is for.
+
+For the first few Alpha releases of Maria there may be some edge cases
+that crashes during recovery; We don't like that but we think it's
+better to get the Maria alpha out early to get things tested and get
+more developers on the code early than wait until these are fixed.  We
+do however think that the bugs are not seriously enough to stop anyone
+from starting to test and even use Maria for real (as long as they are
+prepared to upgrade to next MySQL-Maria release ASAP).
+
+If you have found a bug that is not listed here, please add it to
+http://bugs.mysql.com/ so that we can either fix it for next release
+or in the worst case add it here for others to know!
+
+
+Known bugs that are planned to be fixed before next minor release
+=================================================================
+
+- If mysqld crashed or is killed during REPAIR or OPTIMIZE, Maria will not
+  be able to automaticly repair the table again;  You must manually run
+  REPAIR on the table again after mysqld is started.
+
+- If mysqld crashes during batch insert into an empty table,
+  (This includes LOAD DATA INFILE, SELECT ... INSERT and INSERT (many rows))
+  Maria repair may not be able to recreate the empty table. In this case
+  You must manually run either REPAIR TABLE or TRUNCATE to fix the table.
+
+- If the log files are damaged or inconsistent, Maria may fail to start.
+  We should fix that if this happens and mysqld is restarted (thanks to
+  mysqld_safe, instance manager or other script) it should disregard the
+  old logs, start anyway and automaticly repair any tables that was found
+  to be crashed on open.
+  Temporary fix is to remove or maria_log.???????? files from the data
+  directory, restart mysqld and run CHECK TABLE / REPAIR TABLE or 
+  mysqlcheck on your Maria tables
+
+
+Known bugs that are planned to be fixed before Beta
+===================================================
+
+- If we get a write failure on disk (disk full or disk error) for the
+  log, we should stop all usage of transactional tables and mark all
+  transactional tables that are changed as crashed.
+  For the moment, if this happens, you have to take down mysqld,
+  remove all logs, restart mysqld and repair your tables.
+
+  If you get the related error:
+  "Disk is full writing '/usr/local/mysql/var/maria_log.????????' (Errcode: 28)
+   Waiting for someone to free space..."
+  you should either free disk space, in which Maria will continue as before
+  or kill mysqld, remove logs and repair tables.
+
+
+Missing features that is planned to fix before Beta
+===================================================
+
+- We will add an maria-recover option to automaticly repair any
+  crashed tables on open. (This is needed for not transactional tables
+  and also in edge cases for transactional tables when the table
+  crashed because of a bug in  MySQL or Maria code)
+- Multiple concurrent inserts & multiple concurrent readers at same time
+  with full MVCC control.  Note that UPDATE and DELETE will still be
+  blocking (as with MyISAM)
+- COUNT(*) and TABLE CHECKSUM under MVCC (ie, they are instant and kept up
+  to date even with multiple inserter)
+- Recovery of fulltext and GIS indexes.
+
+
+Features planned for future releases
