New Features

  • MvCALL now uses HTTP/1.1 for requests and supports responses returned with chunked Transfer-Encoding.
  • SNI (Server Name Indication) is now supported for SSL/TLS connections. New configuration option MvCONFIG_SSL_SNI (environment) or "usesni" (3.x) controls whether the TLS hostname extension is set, and may contain one of the following values:
    • auto: (default) SNI is enabled for OpenSSL 1.x and newer, disabled for OpenSSL 0.9.x and older (due to bugs in the older implementations)
    • 0: SNI is disabled for all OpenSSL versions
    • 1: SNI is enabled for all OpenSSL versions

MivaSQL Changes

  • A new function, LENGTH( field ) may now be used in MivaSQL queries. The function returns the length, in bytes, of the value passed to it.
  • MivaSQL now supports BETWEEN x AND y in SELECT queries.

 

StoreMorph Changes

  • Quotation marks in StoreMorph expression constants may now be escaped with a backslash. Example: <mvt:eval expr="'<product count=\"80\">'" />
  • New StoreMorph tags <mvt:foreachcontinue />, <mvt:foreachstop />, <mvt:whilecontinue /> and <mvt:whilestop /> allow greater control of foreach and while loops.

New Template Language Updates with Miva Empresa 5.20 Engine 

 

New API Functions

char *mvVariable_Value_NS( mvVariable variable, int *length )
Returns a string containing the value of "variable", with internal ASCII NULLs removed. *length receives the new length of the string. The return value is NULL terminated.

mvHTTPResponse mvNetwork_HTTP_Request( mvProgram program, const char *method, const char *url, double http_version, const char *content, const char *contenttype, int contentlength )
Makes an HTTP request using the protocol version specified by "http_version". The remaining parameters are identical to mvNetwork_Open_URL. Returns an mvHTTPResponse object, or NULL on failure.

int mvHTTPResponse_Status_Code( mvHTTPResponse response )
Returns the numeric HTTP response code of a response returned by mvNetwork_HTTP_Request.

int mvHTTPResponse_Content_Length( mvHTTPResponse response )
Returns the value of the Content-Length response header (if specified by the server).

int mvHTTPResponse_Read( mvHTTPResponse response, char *buffer, int size )
Reads "size" bytes from "response", storing the result in "buffer". Returns the number of bytes read, or -1 on error.

void mvHTTPResponse_Close( mvHTTPResponse response )
Closes an mvHTTPResponse and frees all associated memory.

const char *mvHTTPResponse_Error( mvProgram program, mvHTTPResponse response )
Returns a textual description of an error returned by mvHTTPResponse_Read.
