    • of a registered module without location hint
    • of a module with location hint
  • change XQueryContext to allow imports again
  • change SourceFactory to work with contextPath set to "."

Reference:

I don't want to upset anyone, but I just wanted to point out that this is the wrong approach to fixing this issue.

This is fixing an additional bug I found while creating tests:

see importLibraryFromDbLocation and importLibraryFromXMLDBLocation

Yes, I understood that, but it still is the wrong approach.

@adamretter Could you explain why you think this is the wrong approach and how do you think it should be solved correctly?

Adding the functx library to auto deploy in the conf.xml used for all tests leads to test failures.
There are, however, other configurations that do have functx loaded, see src/test/resources-filtered/org/exist/xquery/functions/transform/conf.xml.

Should I, either

  1. limit the application of the conf.xml with functx to only xquery tests
  2. limit the application of the conf.xml with functx to only moduleImport tests
  3. try to import other modules that are present without adding functx

If the issue isn't functx-specific, then choice 3 sounds like it would address the issue.

You should not have to modify conf.xml for this.

@joewiz module imports are certainly not functx specific.

I ended up using option 2, only use conf.xml with functx loaded via autodeploy for ModuleImportTest.

For the tests to work we need do need to add a pure library package to exist. It just happens that the functx-1.0.1.xar is already part of the test fixtures in
src/test/resources/functx/functx-1.0.1.xar.
With that we have a library module that can be imported with and without location hint.

So far as I can see there is no other way than to add another configuration with functx added to autodeploy.
We could change both src/test/java/org/exist/xquery/functions/transform/TransformFromPkgTest.java and src/test/java/org/exist/xquery/ModuleImportTest.java test classes to both use a conf-with-functx.xml to make its use-case more obvious and also re-usable.
