I reformulate the messages.
Changed version in preprocessor conditions to avoid compilation
warnings in Debian 9.
Disabled sign-compare check for generated files in DML/DDL.
Fixed pragmas that disables compilation checks.
DDLProc now returns an error if it couldn't cwd.
Use either auto_ptr or unique_ptr depending on GCC version.
Fixes the following:
* Read past buffer end in intToDatetime / intToTime
* Allow intToTime to convert datetime
* Allow intToTime to convert shortened time values
* Allow stringToTime to convert datetime and int time values
* Fix saturation / bad values in intToTime and stringToTime
* Fix TIME return in STR_TO_DATE()
* Fix NULL return on type inequality for TIMEDIFF()
* Fix zero day calculation error in ADDTIME()/SUBTIME()
* Fix DATETIME to int calculation error in aggregate bit operations
* Make the new harderning flags optional with -DSECURITY_HARDENED_NEW
SQL-92 basically specifies for a NOPAD collation that only space should
be ignored for matches. Tabs and other whitespace are handled
differently. We don't fully support collations yet so we assume the
defaults.
For equality string matches other engines ignore trailing whitespace
(this does not apply to LIKE matches). So we should do the same. This
patch trims whitespace for MIN/MAX extent elimination checks, fixed
width columns and dictionary columns during equality matches against
constants (SELECT * FROM t1 WHERE b = 'ABC').
Date limit of year 1400 was used due to Boost's limits.
This patch strips out the use of Boost for date handling and sets the
lower limit to year 1000.
