Native X.509, RSA and HSM Support

By Arnaud Bouchez, 2023-12-09. Open Source › mORMot Framework

Today, almost all computer security relies on asymmetric cryptography and X.509 certificates as file or hardware modules.
And the RSA algorithm is still used to sign the vast majority of those certificates. Even if there are better options (like ECC-256), RSA-2048 seems the actual standard, at least still allowed for a few years.

So we added pure pascal RSA cryptography and X.509 certificates support in mORMot.
Last but not least, we also added Hardware Security Modules support via the PKCS#11 standard.
Until now, we were mostly relying on OpenSSL, but a native embedded solution would be smaller in code size, better for reducing dependencies, and easier to work with (especially for HSM). The main idea is to offer only safe algorithms and methods, so that you can write reliable software, even if you are no cryptographic expert.

The LUTI and the mORMot

By Arnaud Bouchez, 2023-07-20. Open Source › mORMot Framework

Since its earliest days, our mORMot framework did offer extensive regression tests. In fact, it is fully test-driven, and almost 78 million individual tests are performed to cover all its abilities:

We just integrated those tests to the TranquilIT build farm, and its great LUTI tool. So we have now continuous integration tests over several versions of Windows, Linux, and even Mac!
LUTI is the best mORMot's friends these days.

New Command Line Parser in mORMot 2

By Arnaud Bouchez, 2023-04-19. Open Source › mORMot Framework

For most projects, we want to be able to pass some custom values when starting it.
The command line is then used to add this additional information.

We have ParamStr and ParamCount global functions, enough to retrieve the information. You may also use FindCmdLineSwitch for something more easy to work with.
The Lazarus RTL offers some additional methods like hasOption or getOptionValue or checkOptions in its TCustomApplication class. Their are better, but not so easy to use, and not available on Delphi.

We just committed a new command line parser to our Open Source mORMot 2 framework, which works on both Delphi and FPC, follows both Windows and POSIX/Linux conventions, and has much more features (like automated generation of the help message), in an innovative and easy workflow.

Modern Pascal is Still in the Race

By Arnaud Bouchez, 2022-11-26. Pascal Programming

A recent poll on the Lazarus/FPC forum highlighted a fact: pascal coders are older than most coders. Usually, at our age, we should be managers, not developers. But we like coding in pascal. It is still fun after decades!
But does it mean that you should not use pascal for any new project? Are the language/compilers/libraries outdated?
In the company I currently work for, we have young coders, just out-of-school or still-in-school, which joined the team and write great code!

And a recent thread in this very same forum was about comparing languages to implement a REST server, in C#, Go, Scala, TypeScript, Elixir and Rust.
Several pascal versions are about to be contributed, one in which mORMot shines.

New Client for MongoDB 5.1/6 Support

By Arnaud Bouchez, 2022-08-12. Open Source › mORMot Framework

Starting with its version 5.1, MongoDB disabled the legacy protocol used for communication since its beginning.
As a consequence, our mORMot client was not able to communicate any more with the latest versions of MongoDB instances.

Last week, we made a deep rewrite of mormot.db.nosql.mongodb.pas, which changed the default protocol to use the new layout on the wire. Now messages use regular MongoDB Database Commands, with automated compression if needed.

No change is needed in your end-user MongoDB or ORM/ODM code. The upgrade is as simple as update your mORMot 2 source, then recompile.

New Async HTTP/WebSocket Server on mORMot 2

By Arnaud Bouchez, 2022-05-21. Open Source › mORMot Framework

The HTTP server is one main part of any SOA/REST service, by design.
It is the main entry point of all incoming requests. So it should better be stable and efficient. And should be able to scale in the future, if needed.

There have always been several HTTP servers in mORMot. You can use the HTTP server class you need.
In mORMot 2, we added two new server classes, one for publishing over HTTP, another able to upgrade to WebSockets. The main difference is that they are fully event-driven, so their thread pool is able to scale with thousands of concurrent connections, with a fixed number of threads. They are a response to the limitations of our previous socket server.

mORMot 2 ORM Performance

By Arnaud Bouchez, 2022-02-15. Open Source › mORMot Framework

The official release of mORMot 2 is around the edge. It may be the occasion to show some data persistence performance numbers, in respect to mORMot 1.

For the version 2 of our framework, its ORM feature has been enhanced and tuned in several aspects: REST routing optimization, ORM/JSON serialization, and in-memory and SQL engines tuning. Numbers are talking. You could compare with any other solution, and compile and run the tests by yourself for both framework, and see how it goes on your own computer or server.
In a nutshell, we almost reach 1 million inserts per second on SQLite3, and are above the million inserts in our in-memory engine. Reading speed is 1.2 million and 1.7 million respectively. From the object to the storage, and back. And forcing AES-CTR encryption on disk almost don't change anything. Now we are talking.

Three Locks To Rule Them All

By Arnaud Bouchez, 2022-01-22. Open Source › mORMot Framework

To ensure thread-safety, especially on server side, we usually protect code with critical sections, or locks. In recent Delphi revisions, we have the TMonitor feature, but I would rather trust the OS for locks, which are implemented using Windows Critical Sections, or POSIX futex/mutex.

But all locks are not born equal. Most of the time, the overhead of a Critical Section WinAPI or the pthread library is not needed.
So, in mORMot 2, we introduced several native locks in addition to those OS locks, with multi-read/single-write abilities, or re-entrancy.

mORMot 2 on Ampere AARM64 CPU

By Arnaud Bouchez, 2021-08-17. Open Source › mORMot Framework

Last weeks, we have enhanced mORMot support to one of the more powerful AARM64 CPU available: the Ampere Altra CPU, as made available on the Oracle Cloud Infrastructure.

Long story short, this is an amazing hardware to run on server side, with performance close to what Intel/AMD offers, but with almost linear multi-core scalability. The FPC compiler is able to run good code on it, and our mORMot 2 library is able to use the hardware accelerated opcodes for AES, SHA2, and crc32/crc32c.
