In cases where we tweak the options we pass to the instrumentation, our code did not handle this very well. This could lead to certain options missing when init is called again later, as we updated the config with incomplete/wrong options.
To fix this properly, I added a new variant to
generateInstrumentOnce
which accepts a class and an options transformer, which ensures that the options are always correctly transformed, no matter if called the first or second time.(The code to make this overloaded
generateInstrumentOnce
function work with TS was pretty tricky, but I think it is good now - type inferral etc. works nicely now!)Fixes #16004
