warnings after uncompressed_length UNCOMPRESSED_LENGTH() did not validate its argument. In particular, if the argument length was less than 4 bytes, an uninitialized memory value was returned as a result. Since the result of COMPRESS() is either an empty string or a 4-byte length prefix followed by compressed data, the bug was fixed by ensuring that the argument of UNCOMPRESSED_LENGTH() is either an empty string or contains at least 5 bytes (as done in UNCOMPRESS()). This is the best we can do to validate input without decompressing.

We don't set null_value to 0 in the Item_func_compress::val_str() for not-NULL results.

- Add a check that length of field to uncompress is longer than 4 bytes. This can be dones as the length of uncompressed data is written as first four bytes of field and thus it can't be valid compressed data.

The UNCOMPRESS() function was not marked as maybe_null, even though it returns NULL on invalid data. This confused the optimizer.

The problem was that we restored SQL_CACHE, SQL_NO_CACHE flags in SELECT statement from internal structures based on value set later at runtime, not the original value set by the user. The solution is to remember that original value.

Added more DBUG statements Ensure that we are comparing end space with BINARY strings Use 'any_db' instead of '' to mean any database. (For HANDLER command) Only strip ' ' when comparing CHAR, not other space-like characters (like \t)

Cleaned up (and disabled part of) date/time/datetime format patch. One can't anymore change default read/write date/time/formats. This is becasue the non standard datetime formats can't be compared as strings and MySQL does still a lot of datetime comparisons as strings Changed flag argument to str_to_TIME() and get_date() from bool to uint Removed THD from str_to_xxxx functions and Item class. Fixed core dump when doing --print-defaults Move some common string functions to strfunc.cc Dates as strings are now of type my_charset_bin instead of default_charset() Introduce IDENT_QUOTED to not have to create an extra copy of simple identifiers (all chars < 128) Removed xxx_FORMAT_TYPE enums and replaced them with the old TIMESTAMP_xxx enums Renamed some TIMESTAMP_xxx enums to more appropriate names Use defines instead of integers for date/time/datetime string lengths Added to build system and use the new my_strtoll10() function.
