Introducing mORMot's architecture and design principles

We have just released a set of slides introducing 

  • ORM, SOA, REST, JSON, MVC, MVVM, SOLID, Mocks/Stubs, Domain-Driven Design concepts with Delphi, 
  • and showing some sample code using our Open Source mORMot framework.

You can follow the public link on Google Drive!

This is a great opportunity to discovers some patterns you may not be familiar with, and find out how mORMot try to implement them.
This set of slides may be less intimidating than our huge documentation - do not be terrified by our Online Documentation!
The first set of pages (presenting architecture and design principles) is worth reading.

Feedback is welcome on our forum, as usual.

Some enhancements to REST routing of interface-based services

We have just committed some enhancements to interface-based service process.

TSQLRestRoutingREST will now recognize several URI schemes, like new  root/Calculator/Add?n1=1&n2=2 alternative could be pretty convenient to be consumed from some REST clients.

Please find here a documentation update.

AES encryption over HTTP

In addition to regular HTTPS flow encryption, which is not easy to setup due to the needed certificates, mORMot proposes a proprietary encryption scheme. It is based on SHA-256 and AES-256/CTR algorithms, so is known to be secure.

You do not need to setup anything on the server or the client configuration, just run the TSQLHttpClient and TSQLHttpServer classes with the corresponding parameters.

Thread-safety of mORMot

We tried to make mORMot at the same time fast and safe, and able to scale with the best possible performance on the hardware it runs on.
Multi-threading is the key to better usage of modern multi-core CPUs, and also client responsiveness.

As a result, on the Server side, our framework was designed to be thread-safe.

On typical production use, the mORMot HTTP server will run on its own optimized thread pool, then call the TSQLRestServer.URI method. This method is therefore expected to be thread-safe, e.g. from the TSQLHttpServer. Request method. Thanks to the RESTful approach of our framework, this method is the only one which is expected to be thread-safe, since it is the single entry point of the whole server. This KISS design ensure better test coverage.

Let us see now how this works, and publish some benchmarks to test how efficient it has been implemented.

HTTP server using fast http.sys kernel-mode server

Since Windows XP SP2 and Windows Server 2003, the Operating System provides a kernel stack to handle HTTP requests. This http.sys driver is in fact a full featured HTTP server, running in kernel mode. It is part of the networking subsystem of the Windows operating system, as a core component.

The SynCrtSock unit can now implement a HTTP server based on this component. Of course, our SQLite3 framework will use it. If it's not available, it will launch our pure Delphi optimized HTTP server, using I/O completion ports and a Thread Pool.
