[*] Use a .sig file to verify that the corresponding file (without the .sig suffix) is intact. First, be sure to download both the .sig file and the corresponding tarball. Then, run a command like this:
gpg --verify .sig
If that command fails because you don't have the required public key, then run this command to import it:
gpg --keyserver keys.gnupg.net --recv-keys 1A858392E331EAFDB8C27FFBF3C1A0D9C1D65273
and rerun the
gpg --verify command.
Changes in 2.16.4 since 2.16.3
- The different queue sizes: component, defer, external can now be set
--queue-size-external. The defaults are respectively: 3, 2 and 1.
- The different queue sizes: component, defer, external can now be set individually using
Noteworthy bug fixes
A bug was fixed in the type name lookup of a formal parameter binding (a <- b).
The C# code generator now supports foreign components returning a enum that is defined in an interface.
The C++ code generator now supports imported foreign componenents.
The well-formedness check no longer crashes on a binary expression with a data constant.
A bug was fixed in the verifier that could lead to a false positive for models that have a blocking skip race.
The well-formedness check now reports declarative statements inside a function as being incorrect.
A bug was fixed in the verifier for reporting queue-full cases for an external port. As a result, queue-full is now reported during the illegal check and not as part of the deadlock check.
dzn simulatecommand now exits gracefully when no dezyne model is found.
Dezyne is a programming language and a set of tools to specify, validate, verify, simulate, document, and implement concurrent control software for embedded and cyber-physical systems.
The Dezyne language has formal semantics expressed in mCRL2 developed at the department of Mathematics and Computer Science of the Eindhoven University of Technology (TUE). Dezyne requires that every model is finite, deterministic and free of deadlocks, livelocks, and contract violations. This achieved by means of the language itself as well as builtin verification through model checking. This allows the construction of complex systems by assembling independently verified components.
Dezyne is free software, it is distributed under the terms of the GNU Affero General Public Licence version 3 or later.
Verum, the organization behind the Dezyne language, is committed to continuing to invest in the language for the benefit of all its users. Verum assists its customers and partners in solving the software challenges of today and tomorrow, by offering expert consultancy on the application of the Dezyne language and the development and use of its tools, as well as on Verum's commercial tools like Verum-Dezyne's IDE support based on the LSP (Language Server Protocol), interactive integrated graphics, interactive simulation, (custom) code generation and (custom) runtime library support.
