Releasenotes tntnet 2.2

Cxxtools 2.2 is needed

Cxxtools version 2.2 is needed now in tntnet.

New proxy module

The new module proxy@tntnet allows forwarding request to other http servers.

Secure session scope for variables only valid in ssl sessions

A new scope type <%securesession> allows users to define variables which are only valid in ssl connections. Also a separate cookie is sent which a attribute to advise the browser to use it only when ssl is enables.

Configure tntnet with xml (or json) including logging

Previously a tntnet was configured with a text file with a simple but proprietary format. Logging was configured in a separate file with a different format. Both is combined now in a single xml file.

Remove cgi library

There used to be a library, which allows to run ecpp components as cgi processes. The use was limited and the performance in cgi is always bad. As far as I know no one has used it (for good reason). Hence it is removed now.

Extend url mapping with mapping by method or ssl

Mapping requests to components is extended. Not only the url can be used as a condition but also the http method or ssl state. The previous separate mapping per virtual host is now also defined as a mapping condition.

Use serialization framework to read %config variables from tntnet configuration to support complex configurations

The ecpp tag <%config> allows web applications to read values from the tntnet configuration file. Formerly only a scalar variable could be read. Now using the cxxtools serialization complex objects can be configured and passed to a web application.

ecpp compiler do not stop on first error any more but tries to find more problems

The ecpp compiler ecppc stopped compiling on the first error. Now it tries to recover and continues compiling and reporting errors.

Allow applications to clear the current session

Calling the new method request.clearSession() clears all session variables after the current request.

Read filenames for multibinary component optionally from file using option -i in ecppc

Multibinary components contain a collection of static files, which is compiled as a single tntnet component. This helps saving overhead since each component needs some code, which makes it callable. Since the list of static files used in a web application may be quite long, it is often convenient to maintain the list in a separate file. Also a very long list may extend the maximum allowed length of a shell command. Now ecppc can read the list from a file to solve that.

Arguments in url mapping have now names

When mapping a request to a component, arguments can be passed from the configuration to the component. Previously it was just a list of values. Now the values has names, which makes handling easier and more readable.

Allow distinquishing between GET and POST arguments

Ecpp allows defining query parameters using a <%args> tag. Tntnet passed here all GET and POST parameters. For developers it was difficult to find out, if arguments were passed via GET or POST. Now arguments can be defined in a <%get> or <%post> section to get only the GET or POST parameters.

Bugfixes and optimizations

Some minor bugfixes and optimizations are done in tntnet.
