| <h4>Download</h4> |
| <p> |
| Rivet 3.0 is available for download from ASF mirror sites. Check the |
| <a href="download.html">download page</a> |
| |
| for information about |
| downloading the source code. If you plan to run Rivet on Linux or Free-BSD and |
| you don't want to get bothered building the module yourself then usually, |
| after a few weeks from release, packages for the most popular |
| Linux distributions become available |
| </p> |
| <p> |
| Code integrity for this release can be checked using the |
| public keys in the <a href="http://www.apache.org/dist/tcl/KEYS">KEYS</a> |
| |
| file. |
| </p> |
| <h3>Release Notes</h3> |
| <h4>Requirements</h4> |
| <p> |
| Rivet 3.0 is tested and works with the Apache Webserver version 2.4 (running any |
| MPM) and requires Tcl >= 8.6.1. Rivet 3.0 now supports also the Apache Webserver when running on the |
| MS-Windows family of operative systems. The module has been built on MS-Windows |
| through the <a href="https://cmake.org/">CMake</a> |
| |
| build system using the |
| <a href="https://www.visualstudio.com/downloads/#build-tools-for-visual-studio-2017">Visual Studio Community 2017</a> |
| |
| |
| compiler. |
| </p> |
| <h4>Apache MPM and Rivet Bridge Modules</h4> |
| <p> |
| Rivet 3.0 is a major rewriting of mod_rivet, the Apache HTTP Websever module |
| at the core of Rivet. Unlike in previous versions of mod_rivet which only supported |
| the <a href="https://httpd.apache.org/docs/2.4/mod/prefork.html">prefork MPM</a> |
| |
| |
| (<a href="https://httpd.apache.org/docs/2.4/mpm.html">Multiprocessing Module</a> |
| |
| ), |
| starting with 3.0 we attained full support of different MPM for the Apache framework. |
| |
| Threaded MPM integration was achieved by making mod_rivet multithreaded and modular itself, |
| introducing the mod_rivet/MPM bridge concept. We developed a set of loadable modules which |
| are supposed not only to overcome the issues related to threading but also to offer |
| the best possible MPM mod_rivet integration. |
| As a side effect of this modular design, mod_rivet is not only able to |
| integrate with its environment, but also to work as a framework for writing more MPM bridges |
| designed along different multi-threading schemes and workload management models. See the |
| internals section of the <a href="http://tcl.apache.org/rivet/manual3.0/">rivet manual</a> |
| |
| |
| for further reading. MPM bridges are loaded accordingly |
| to a heuristics of rules based on the Apache introspection calls, but they can be determined |
| in the configuration. Only a bridge can be loaded at a time. |
| </p> |
| <p> |
| Version 3.0 is a drop-in replacement of any earlier version of Rivet but there are |
| new features that can deeply change the way you have so far developed your Rivet |
| based applications |
| </p> |
| <h4>New Request Processing Scheme</h4> |
| <p> |
| In Rivet 2.x request processing was performed by chaining together 3 scripts |
| |
| <ul> |
| <li> |
| <strong>BeforeScript</strong> |
| |
| , if defined in the configuration </li> |
| <li>The Tcl script or rvt template referenced by the URL and determined with respect to the |
| DocumentRoot and following other resource determination methods, such as the ones offered by |
| mod_alias and mod_rewrite.</li> |
| <li> |
| <strong>AfterScript</strong> |
| |
| if defined in the configuration </li> |
| </ul> |
| |
| |
| Errors and exceptions (raised by the ::rivet::abort_page command) are handled by the |
| <strong>ErrorScript</strong> |
| |
| and <strong>AbortScript</strong> |
| |
| (<strong>ErrorScript</strong> |
| |
| |
| has a default implementation if left undefined) |
| </p> |
| <p> |
| Rivet 3.0 implements a new request processing scheme entirely based on Tcl. |
| By default rivet 3.0 provides compatibility with the version 2.x scheme |
| but this can be entirely overridden by the developer replacing the central request |
| handling procedure. |
| </p> |
| <h4>Packages</h4> |
| <p> |
| Rivet comes with the usual collection of packages. Some of the available packages are |
| </p> |
| <ul> |
| <li> |
| <strong>Asciiglyphs</strong> |
| |
| : a ASCII-art character printer. Character typefaces were shamelessly taken from |
| the code of the <a href="https://www.fossil-scm.org/">Fossil DVCS</a> |
| |
| under permission of Richard Hipp, |
| Fossil's mastermind </li> |
| <li> |
| <strong>Calendar</strong> |
| |
| : a class to print text, HTML and XML based calendar tables like the ones printed |
| by the Unix '<a href="https://en.wikipedia.org/wiki/Cal_(Unix)">cal</a> |
| |
| ' command </li> |
| <li> |
| <strong>DIO</strong> |
| |
| : a generic, object-oriented interface to SQL databases. Its main goal is |
| to be as generic as possible </li> |
| <li> |
| <strong>Entities</strong> |
| |
| : The RivetEntities package was kindly provided by Harald Oehlmann |
| and is largely taken from a simple yet clever encoder/decoder of HTML entities starting from a utf-8 |
| character string. The original code writted by Andy Goth is at http://wiki.tcl.tk/26403. |
| Package entities extends the functionality in the original code combining it with Tcl's 'encoding' |
| command to encode/decode from any supported encoding </li> |
| <li> |
| <strong>Form</strong> |
| |
| : The form package is a utility for generating html forms. |
| A form object command saves the programmer from typing the cumbersome html code of input elements, |
| working out a solution for better standardization and readability of the code </li> |
| <li> |
| <strong>Formbroker</strong> |
| |
| : The FormBroker package creates instances of objects representing a |
| form data description. These objects offer a simple interface of methods meant to validate and control |
| data as typically posted through an HTML form </li> |
| <li> |
| <strong>session</strong> |
| |
| : This is session management code. It provides an interface to allow you to generate and track a |
| browser's visit as a "session", giving you a unique session ID and an interface for storing and |
| retrieving data for that session on the server. </li> |
| </ul> |
