Synopse PDF Engine 1.18

Our SynPdf library was released as part of every mORMot version. But the stand-alone .zip was still in 1.15 revision. I have updated it, and now it reflects the latest version from our source code repository (i.e. 1.18). Open Source, working from Delphi 5 up to XE3. Thanks to nice proposals - like  […]

Authentication in mORMot using Windows credentials

By default, the hash of the user password is stored safely on the server side. This may be an issue for corporate applications, since a new user name / password pair is to be defined by each client, which may be annoying.

Since revision 1.18 of the framework, mORMot is able to use Windows Authentication to identify any user. That is, the user does not need to enter any name nor password, but her/his Windows credentials, as entered at Windows session startup, will be used.

Thanks a lot Chaa for making public your code proposal!
Open Source is so great sometimes!
Keep the good work!

Updated mORMot benchmarks on another HW configuration

With a refreshed hardware, and the latest code modifications of the framework code, I run again the benchmark sample.

The new PC has an Intel Core i7-2600 CPU, running on Windows Seven 64-bit, with anti-virus (Norton) fully enabled.
Oracle 11g database is remotely accessed over a corporate network, so latency and bandwidth is not optimal.
Still no SSD, but a standard 7200 rpm hard drive of 500 GB.

The results are impressive, when compared to the previous run using a Core 2 Duo CPU - mORMot's optimized code achieves amazing speed on this platform.
And I guess the 8MB of L3 cache of the Core i7 does wonders with our code.

"Trop c'est trop" - No Client-Server for XE3 PRO users

Here is some unbelievable news retrieved from "Te Waka o Delphi" blog:

From XE3 onwards, your Delphi Professional EULA will prohibit you from using Delphi Professional for anything other than local data access.
If you want to build client/server database applications using Delphi Professional, you will be required to purchase a “Client/Server Add-On” pack.

This goes beyond the fact that you do not get (or can otherwise use or install) client/server drivers for the DBExpress or other “built in” data access frameworks, but extends even to 3rd party data access technologies.
That is, whatever you may be able to do or achieve – technically – using some 3rd party component or library with you Delphi Professional compiler, you cannot legally create a client/server application.
Never mind any 3rd party components or libraries, this same prohibition will apply even if you are using naked, unadorned Microsoft ADO.

Damn show-stopper for me.
Embarcadero is killing Delphi.

Our very own mORMot Open-Source framework is fully Client-Server oriented, and allow creating scalable Client-Server applications even with an Oracle DB system back-end, even with XE2 starter edition (direct access, without any DB.pas / DBExpress layer).

Synopse mORMot Framework 1.16

Our Open Source mORMot framework is now available in revision 1.16.

The main new features are the following:

Thanks to its features, mORMot is now able to provide a stand-alone Domain-Driven Design framework for Delphi.

Quite a long and nice road for a little mORMot, and more to come!

Smart: mORMot, from Delphi to JavaScript

Did you hear from the great Smart project?

It is an IDE and some source runtime able to develop and compile an Object-Pascal project into a HTML 5 / CSS 3 / JavaScript embedded application.
It does target AJAX Mobile application creation (i.e. Android and iPhone/iPad apps running Web-Kit).
You'll get an unique .html file containing the whole client-side application: it won't need any server side implementation. Using a third-party tool like PhoneGap, you'd be able to supply your customers with true native applications, running without any network, and accessing the full power of any modern Smart Phone.

Smart is a great candidate for implementing rich client-side AJAX applications, to work with our client-server mORMot framework.

In order to interface Smart code with mORMot, we started implementing some low-level code to work with our RESTful authentication scheme.

So we'll need to implement some Smart dedicated Open Source code implementing crc32 and SHA-256 hashing.

AJAX authentication

A nice framework user, named esmondb, did write and publish some JavaScript code to handle our RESTful authentication mechanism.

It seems to work well, and implements all secure hashing and challenging.
Our authentication mechanism is much more advanced than the one used by DataSnap - which is a basic HTTP authentication with the password transmitted in clear (this is the reason why it shall better be used over HTTPS, whereas mORMot can be used over plain HTTP).
Resulting JavaScript code seems not difficult to follow, even for a no JS expert like me.
