Policy: java1-runtime
Hi,
I was reported that my package, which "Depends: java-virtual-machine,
java1-runtime", could not be installed of a user's machine, who has
blackdown's j2sdk1.4 and j2re1.4 installed. j2re1.4 "Provides:
java-virtual-machine, java2-runtime".
Something seems to be wrong, since the package should obviously be able
to run with j2re1.4.
The policy says:
Programs /must/ depend on /java-virtual-machine/ and the needed runtime
environment (/java1-runtime/ and/or /java2-runtime/).
[JVMs] can also provide the runtime environment that the package
contains (java1-runtime and/or java2-runtime).
I'm a bit puzzled by the "and/or". What is the difference between
depending (or providing) java2-runtime and depending on both 1 and 2? I
would think that java2 is a superset of java1.
I see two possibilities: either packages that need java1 depend on
java1-runtime | java2-runtime, or java2 runtimes provide java1-runtime
and java2-runtime. The policy should be clarified in both cases. I think
the second case makes more sense, since there are far less JVMs than
programs/libraries, so there is less work to do, and less risk to have
faulty packages.
I propose the following changes in the policy, instead of the above
paragraphs:
Programs /must/ depend on /java-virtual-machine/ and the needed runtime
environment (/java1-runtime/ or /java2-runtime/).
[JVMs] can also provide the runtime environment that the package
contains (java1-runtime or both java1-runtime and java2-runtime).
In particular, blackdown's packages should have:
Provides: java1-runtime, java2-runtime

PS: Section 2.1, second paragraph, "I should" -> "They should".
