Platform Support

• 64-bit Windows is now support for both IIS 6.x (ISAPI) and IIS 7.0 and newer.

API Changes

void mvProgram_SetCharacterSet( mvProgram program, const char *charset, int charset_len );

            Sets the current character set to "charset"

char *mvProgram_JavaScriptString_Encode( mvProgram program, const char *data, int data_length, int *result_length, int *result_size );

            Encodes "data" in a format suitable for use inside a JavaScript quoted

            string declaration honoring the current character set.

            Returns a newly allocated buffer containing the encoded string.

            "result_length" is populated with the length, in bytes, of the encoded

            string

            "result_size" is populated with the length, in bytes, of the allocated

            buffer

New Builtin Functions

encodejavascriptstring( string )

            Encodes "string" in a format suitable for use inside a JavaScript quoted

            string declaration, honoring the current character set.

            Returns the encoded string.

miva_json_decode( data, output var )

            Decodes a block of JSON data in "data", returning the parsed aggregate

            value in "output".

            Returns 1 on success, 0 on error.

miva_json_decode_last_error()

            Returns a textual description of the most recent parsing error encountered

            by json_decode

StoreMorph Changes

• New tag <mvt:call> exposes MvCALL functionality to the template language.
• Attributes are identical to those for MvCALL.
• <mvt:callcontinue /> and <mvt:callstop /> are permitted.
• New tag <mvt:do> exposes MvDO functionality to the template language.
• Attributes are identical to those for MvDO.
• New entity method &mvtj allows tokens to be output with the correct encoding  for use within JavaScript quoted strings.

New Features

• Hexadecimal integer constants are now consistently handled across all platforms.

Customer Impact

• The fix for bug 16943 changed the MivaSQL parser in a way that may cause errors in queries that worked in previous versions, if the queries contain spurious punctuation characters, such as “!” or “}”.  Users are advised to make sure they are not affected by this change prior to making use of the new template language features, so that they can roll back to a previous version of Miva Empresa if required.

Rollback Procedure

• Uninstall v5.21 of Empresa and/or the Script Compiler.
• Reinstall the v5.20 version from the standard distribution.
