I am researching code generator tools for company usage. Since we deal in a secure environment, we can only use tools that are not accessible to the internet. If the tool or even a subset of the tools functionality requires internet access, that functionality is not usable to us. Does Papyrus satisfy this criterium?

No, neither Papyrus itself nor the Eclipse base, nor the Java Runtime does need any internet access. The same is true for the code generation tooling. Even better, as it is all free open source software you can even inspect the source code and build your own trusted binaries. Furthermore you can host it on a pure free open source Linux (i.e. Debian) distribution which is free open source software too.
Given that, Papyrus shall even fit the most paranoid environments.

Hi

... probably.

Unfortunately there are sometimes bugs, particularly in relation to model nsURIs that look like URLs and are sometimes accidentally accessed as such. 5 years ago, OCL had a bad bug whereby its library model was redundantly loaded from Eclipse.org causing at least a few milliseconds of delay and potentially a 20 second connection time out before the code fell back on the built-in copy. OCL JUnit tests now install a NoHttpURIHandlerImpl that throws an IOException if testing attempts to access the net. Similarly I have seen a misconfigured Mylyn Wikitext access its schema off the net which is particularly confusing since the net copy is not well-formed.

It is worth running code with Wireshark and/or the Internet disconnected every so often to detect accidental use of non-local facilities.

So, probably ...

Regards

Hi,
Two years ago, I did a complete Papyrus code generation project unplugged. That alone was some 400h unplugged -- at the beach ;-) No, problems at all.
Quite often I take my bicycle, ride to a nice place at a lake or forest and work there completely unplugged.
Yes, misspelled local nsURIs (name spaces) looking like URLs result in a internet access. Having no internet access this results in an error message. Nothing more. As soon as you have corrected the spelling it works. I would not interpret this as internet required.

Hi

Great, you have actually demonstrated what we expect to be true.
