#1897 — Seed7 Release 2017-07-02

Hello,

I have released a new version of Seed7: seed7_05_20170702.tgz
The download is here: https://sourceforge.net/projects/seed7/files
In the Seed7 programming language new statements and operators can
be declared easily. Types are first class objects and therefore
templates/generics need no special syntax. Object orientation is used
when it brings advantages and not in places when other solutions are
more obvious.

Seed7 is covered by the GPL (and LGPL for the Seed7 runtime library).

Changelog:
- The performance of the function bigStr() in big_rtl.c has been
  improved by a factor of 2.7 (measured with gcc and valgrind when
  str(123456789_**12345) is computed). Now A binary method is used to
  convert large bigInteger numbers to a string.
- The performance of the function bigRadix2To36() in big_rtl.c has
  been improved by a factor of 7.3 (measured with gcc and valgrind
  when 123456789_**12345 radix 7 is computed). Now A binary method is
  used to convert large bigInteger numbers to a string.
- The compiler (s7c.sd7) has been improved to create destructors for
  local DATABASEOBJECTs and SQLSTMTOBJECTs.
- The database driver sql_odbc.c has been improved to support the
  type SQL_BIT.
- The database driver sql_odbc.c has been improved to close the
  the database only after all prepared statements have been freed.
- Support to read BLOBs (Binary large objects) and wide character
  CLOBs (Character large objects) from an ODBC database has been
  added to sql_odbc.c. SQL_DATA_AT_EXEC is used to flag BLOBs and
  CLOBs for the buffer types SQL_CHAR, SQL_VARCHAR, SQL_LONGVARCHAR,
  SQL_WCHAR, SQL_WVARCHAR, SQL_WLONGVARCHAR, SQL_BINARY,
  SQL_VARBINARY and SQL_LONGVARBINARY.
- The function bigInteger(string), which converts a string to a
  bigInteger number, has been added to bigint.s7i.
- Checks that test the conversion of a bigInteger to a string (with
  the function str() and the operators RADIX and radix) have been
  added to chkbig.sd7.
- The example program db7.sd7 has been improved to list column
  headers even when no line was found.
- The functions getConversionDivisor, basicToStri, binaryToStri,
  basicRadix2To36, binaryRadix2To36, uBigDivRem1, bigDivRem1,
  bigDivRemSizeLess and bigDivRem have been added to big_rtl.c.
- The program chkccomp.c has been improved to have better checks for
  utime and fileno.
- Documentation about the macros used have been added to chkccomp.c.
- In src/read_me.txt descriptions of C_COMPILER, C_COMPILER_SCRIPT,
  CC_FLAGS and LINKER have been improved.

Regards,
Thomas Mertes
