HTTP server using fast http.sys kernel-mode server

By AB4327-GANDI, 2011-03-11. Open Source › mORMot Framework

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.

Open Source SynTaskDialog unit for XP,Vista,Seven

By AB4327-GANDI, 2011-03-05. Open Source › Open Source libraries

A task dialog is a dialog box that can be used to display information and receive simple input from the user. Like a message box, it is formatted by the operating system according to parameters you set. However, a task dialog has many more features than a message box.

Windows provides a generic task dialog available since Vista/Seven. But there is none available with previous versions of Windows, i.e. Windows XP or 2K.

This unit (licensed under a MPL/GPL/LGPL tri-license) will use the new TaskDialog API under Vista/Seven, and emulate it with pure Delphi code and standard themed VCL components under XP or 2K. It will compile from Delphi 6 up to XE, and is Unicode ready.

Fast JSON (un)serialization

By AB4327-GANDI, 2011-02-23. Open Source › mORMot Framework

blog

The core of our SQLite3 framework is using JSON for all its Client/Server communication, and also for the internal cache of previous SQL requests.

There is indeed a damn fast JSON generator and parser in the framework.

I've written some functions able to serialize and unserialize not only TSQLRecord (which is the main parent class of our ORM), but any TPersistent class instance.

TIOBE : Pascal in TOP TEN language

By AB4327-GANDI, 2011-02-03. Pascal Programming

blog

The 2011 TIOBE Index is a gauge that has long tracked the rise and fall of programming languages. First developed during the mid-1990s, the index relies on various data sources to gauge the popularity of languages; that is, the extent to which they're used (but not how much they're liked).

The problem is that it split Delphi and Pascal into two diverse categories. Without this distinction, we would be in the top ten!

record and object issue in Delphi 2010

By AB4327-GANDI, 2011-01-29. Pascal Programming

blog

In a previous post, I explained why I still like to use, in some special cases, record or object where using a class doesn't perfectly fit my needs.

I just discovered a non reproducing bug in Delphi 2010, about objects: sometimes, reference-counted objects were not initialized!
