lang/seed8: update to 05_20200308

20200308:

• The new library cpio.s7i has been added. This library supports cpio archive files.
• The new library rpm.s7i has been added. This library supports rpm archive files.
• The new library ar.s7i has been added. This library supports ar archive files.
• The new library subfile.s7i has been added. This library allows to open a part of an existing file as read only file.
• The new library filebits.s7i has been added. This library defines file mode bits used by archive file systems.
• The libraries bin32.s7i and bin64.s7i have been improved to support case statements for the types bin32 and bin64.
• The tarHeader element 'size' has been renamed to 'fileSize' in tar.s7i and tar_cmds.s7i.
• Tests for the operator 'conv' and for the functions compare(), str(), float(), trunc() and round() have been added to chkflt.sd7.
• The program chkccomp.c has been improved to determine the values MINIMUM_TRUNC_ARGUMENT and MAXIMUM_TRUNC_ARGUMENT.
• Definitions of MINIMUM_TRUNC_ARGUMENT and MAXIMUM_TRUNC_ARGUMENT have been added to cc_conf.s7i.
• The compiler (s7c) has been improved (in comp/flt_act.s7i) such that the actions FLT_TRUNC and FLT_ROUND do the correct check for the exception RANGE_ERROR.
• The database driver sql_oci.c has been improved to support the types BINARY_FLOAT and BINARY_DOUBLE.
• Tests for FLOAT and DOUBLE fields have been added to chkdb.sd7.
• A definition of the constant GZIP_MAGIC has been added to gzip.s7i.
• In file.s7i and iobuffer.s7i the functions hasNext() and length() have been changed to use an inout parameter for the file. This fixes a problem in compiled programs with some file systems where also an inout parameter is used for the file.
• The file db_oci.h has been improved to define SQLT_BFLOAT, SQLT_IBFLOAT, SQLT_BDOUBLE and SQLT_IBDOUBLE.
• In fltlib.c the functions flt_trunc() and flt_round() have been improved to do the correct check for the exception RANGE_ERROR.

• The new database driver sql_tds.c has been added. This driver uses the Tabular Data Stream (TDS) protocol to transfer data between database server and client. TDS is used by SQL Server and Sybase. This driver allows the connection to a SQL Server database from Linux.
• The new library db_prop.s7i has been added. This library provides a collection of database properties.
• The example program chkdb.sd7 has been improved:
  • Tests with comments in sql statements have been added.
  • Tests that fetch boolean values from numeric fields have been added.
  • Tests for date, time, datetime and timestamp fields have been added.
• In the library time.s7i the function time() has been improved, to accept more variants of the ISO 8601 time and date format including variants with a time zone.
• The interpreter (s7) has been improved to write the error message of a DATABASE_ERROR, if the exception is not catched.
• In tim_rtl.c the function timUtcFromTimestamp() has been improved to work without calling gmtime() or gmtime_r() or gmtime_s(). Now the function always works with a 64-bit signed timestamp. Gmtime() uses time_t, which can be 32-bit or 64-bit and it can be signed or unsigned.
• In tim_rtl.c the function timToTimestamp() has been improved to work without calling mkutc(). This way the function always works with a 64-bit signed timestamp. Mkutc() is also defined in tim_rtl.c and it uses the system dependend type time_t.
• In tim_rtl.c the functions timToOsTimestamp(), assignTime() and dateFromDaysSince1900() have been added and the functions timFromBigTimestamp() and timToBigTimestamp() have been removed.
• In exec.c the functions par_restore() and loc_restore() have been improved to free unneeded memory, in case an exception has been raised.
• In executl.c the function destroy_local_object() has been improved to optionally ignore exceptions.
• The functions leaveExceptionHandling(), saveFailState() and restoreFailState() have been added to runerr.c. This function is used in executl.c and prclib.c.
• In numutl.c the functions getDecimalBigRational() and getDecimalFloat() have been improved to accept both, a decimal point and a decimal comma.
• In several database drivers the function processStatementStri() has been improved to replace a comment with a space.
• Interpreter and compiler have been improved to support the actions SQL_ROLLBACK, SQL_GET_AUTO_COMMIT and SQL_SET_AUTO_COMMIT.
• The functions sqlRollback(), sqlGetAutoCommit() and sqlSetAutoCommit() have been added to sql_cli.c, sql_lite.c, sql_my.c, sql_oci.c, sql_post.c and sql_rtl.c.
• In the database driver sql_lite.c the functions sqlBindTime() and sqlColumnTime() have been improved to support more time and date formats. The function sqlColumnTime() calls assignTime() to reach this goal.
• In the database driver sql_my.c the function sqlColumnTime() has been improved to correct values, if they are outside of the allowed range.
• The database driver sql_db2.c has been improved to allow that for the functions SQLExecute() and SQLFetch() SUCCESS_WITH_INFO is treated as SQL_SUCCESS.
• The database driver sql_post.c has been improved:
  • Inserting and selecting time fields is now supported under different operating systems and compilers.
  • The type preparedStmtRecord and the functions freePreparedStmt() and sqlPrepare() have been improved such that a prepared statement maintains a dbType reference instead of a connection (PGconn).
  • The functions doExecSql() and implicitCommit() have been added. These functions are used for autocommit and for transaction handling.
• The database driver sql_oci.c has been improved:
  • The function sqlBindTime() has been improved to set the timeZone and to use a nanosecond as unit for the fraction of a second. There is also a check for situations in which the function OCIDateTimeConstruct() fails.
  • The function sqlColumnTime() has been improved to use the function OCIDateTimeGetTimeZoneOffset() to retrieve a timeZone and to use a nanosecond as unit for the fraction of a second.
• The database driver sql_cli.c has been improved:
  • In case of a DATABASE_ERROR exception the native SQL error is assigned to the errorCode.
  • The function freePreparedStmt() has been changed to ignore possible errors of SQLFreeStmt().
  • Binding SQL_BLOB and SQL_CLOB parameters is supported now.
  • Retrieving SQL_SS_TIME2 and SQL_XML columns is supported now.
  • Retrieving datetime2 columns in sqlColumnTime() has been improved to use the function assignTime().
• The database include files db_lite.h, db_my.h, db_oci.h and db_odbc.h have been improved.
• In sql_srv.c the functions connectToServer() and connectToLocalServer() have been improved to return a boolean value instead of a SQLRETURN value.
• In cmd_rtl.c the functions cmdSetATime() and cmdSetMTime() have been improved to use the new function timToOsTimestamp().
• The function determineTdsDefines() has been added to chkccomp.c.
• In exec.c the function suspendInterpreter() has been renamed to doSuspendInterpreter().
