Multi-threading and Delphi

By AB4327-GANDI, 2011-08-28. Pascal Programming

Writing working multi-threaded code is not easy - it's even hard, as as a Delphi expert just wrote in his blog.

In fact, the first step into multi-thread application development could be:

"protect your shared variables with locks (aka critical sections), because you are not sure that the data you read/write is the same for all threads".

The CPU per-core cache is just one of the possible issues, which will lead into reading wrong values. Another issue which may lead into race condition is two threads writing to a resource at the same time: it's impossible to know which value will be stored afterward.

Enhanced Log viewer

By AB4327-GANDI, 2011-08-20. Open Source › Open Source libraries

We already shipped a sophisticated set of logging classes some month ago.

Since then, its features have been enhanced, and the system has been deeply interfaced with our main ORM framework. Now almost all low-level or high-level operations can be logged on request.

But since the log files tend to be huge (for instance, if you set the logging for our unitary tests, the 6,000,000 unitary tests creates a 280 MB log file), a log viewer was definitively in need.

FireMonkey and DXScene

By AB4327-GANDI, 2011-08-11. Pascal Programming

For those how are interested in FireMonkey, I made some screenshots of some DXScene sample app.

It may give you some good starting point about the features of the upcoming Delphi XE2 user interface components.

Framework documentation updated for revision 1.15

By AB4327-GANDI, 2011-08-10. Open Source › mORMot Framework

The framework documentation was just updated.

The general organization of the SAD document (which is the one to be read in all cases) has been refreshed, and is now separated in smaller chapters.

The new official name has been changed into "Synopse SQLite3/mORMot framework"...

Everybody is buzzing about FireMonkey...

Our little mORMot will like FireMonkey!
Here is why...

Close future of the framework: database agnosticism

By AB4327-GANDI, 2011-07-25. Open Source › mORMot Framework

Our ORM RESTful Framework is about to access any available database engine.

It will probably change its name (since it won't use only SQlite3 as database), to become mORMot - could be an acronym for "Manage Object Relational Mapping Over Tables", or whatever you may think of...

We'll still rely on SQLite3 on the server, but a dedicated mechanism will allow to access via OleDB any remote database, and mix those tables content with the native ORM tables of the framework. A flexible Virtual Tables and column mapping will allow any possible architecture: either a new project in pure ORM, either a project relying on an existing database with its own table layout.

SynDBSQLite3: SQLite3 direct access

By AB4327-GANDI, 2011-07-22. Open Source › Open Source libraries

For our ORM framework, we implemented an efficient SQLite3 wrapper, joining statically (i.e. without any external dll) the SQLite3 engine to the executable. SQLite3 is in fact used as the DB kernel of the framework. For instance, thanks to its unique virtual table mechanism, even tables in other databases (like Oracle or MSSQL) are available as if they were SQLite3 tables.

We just made this wrapper independent from our ORM, in a new dedicated unit, named SynSQLite3.pas.

It was an easy task to let this unit be called from our SynDB database abstract classes.
