Seed7 Release 2018-11-25

Hello,


I have released a new version of Seed7: seed7_05_20181125.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:
- In sql_odbc.c the handling of blobs has been improved. Selects with
    normal and blob fields work now independent from the order of fields.
    The functions resizeBindArray() and getClob() have been removed. The
    functions setupParameters(), getBlob(), getData() and fetchBlobs()
    have been added and the function getWCLob() has been improved.
- In sql_odbc.c the handling of time values has been improved to
    support the sql type datetime2 and times with fractions of a second.
    The functions sqlBindTime() and sqlColumnTime() have been improved.
- In sql_odbc.c the binding of bigRational and null values has been
    improved. The functions sqlBindBigRat() and sqlBindNull() have been
    improved.
- In the library duration.s7i the function str() and the operator
    'parse' have been improved to use P[nY][nM][nD][T[nH][nM][n[.n]S]] as
    format for the string representation of a duration.
- In dir_rtl.c the function dirRead() has been improved to use the
    functions conv_from_os_stri() and os_stri_strlen() instead of
    os_stri_to_stri(). This reduces the runtime of dirRead() by 2%
    (measured with gcc and valgrind, when reading 1532 directories).
- In the compiler (in comp/const.s7i) the actions BST_PARSE, FLT_PARSE
    and INT_PARSE have been added to the list of special actions.
- The function duration(), which converts a string to a duration value,
    has been added to duration.s7i.
- The function time(), which converts a string to a time value, has
    been added to time.s7i. Additionally parsing of time literals has
    been improved to support negative years.
- The function bstring(), which converts a string to a bstring value,
    has been added to bstring.s7i.
- The function rand(), which computes a pseudo-random time in a given
    range, has been added to time.s7i.
- Tests for the function float(), which converts a string to a float
    value, have been added to chkflt.sd7.
- The program chkccomp.c has been improved to determine INT64_SIZE
    (the size of __int64), HAS_LLABS, HAS_ABS64, STRINGIFY_WORKS,
    HAS_GMTIME_R and HAS_GMTIME_S.
- Documentation comments have been added or improved in sockbase.s7i,
    fil_rtl.c, fil_unx.c, fil_win.c, soclib.c and soc_rtl.c.
- In heaputl.c the function growStri() has been improved to have a
    smarter behavior in the case when malloc() returns NULL.
- The functions sqlBindDuration and sqlColumnDuration have been
    improved in sql_lite.c, sql_my.c, sql_oci.c, sql_odbc.c and
    sql_post.c.
- The parameter time_zone has been added to the function sqlBindTime()
    in sqllib.c, sql_rtl.h, sql_rtl.c, sql_drv.h, sql_lite.c, sql_my.c,
    sql_oci.c, sql_odbc.c, sql_post.c and comp/sql_act.s7i.
- A function to bind a duration value to a prepared statement has been
    added to the library sql_base.s7i.
- The example program chkdb.sd7 has been improved to check inserting
    and selecting time and duration values into and from a database.
- In sql_lite.c the function sqlColumnTime() has been improved.
- In sql_post.c the functions sqlBindTime() and sqlColumnTime() have
    been improved.
- The functions stringify() and conv_wstri_buf_to_cstri() have been
    added to striutl.c.
- In tim_rtl.c the functions mkutc() and unchecked_mkutc() have been
    improved to work with negative years.
- The function timUtcFromTimestamp() has been added to tim_rtl.c.


Regards,
Thomas Mertes
