Could run some benchmark test to try to ensure we don't reproduce the same @hoc081098 ? 🙏

Yes, I will add it 😊

@arnaudgiuliani I have added some benchmarks.

BenchmarkClass.flatten            avgt   10  146.838 ± 15.775  ms/op
BenchmarkClass.newFlatten         avgt   10    0.880 ±  0.018  ms/op
  • BenchmarkClass.flatten uses flatten of current Koin 3.5.3.
  • BenchmarkClass.newFlatten uses the new implementation of flatten.

Could you check it again 🙏 ?

Great job. I was planning to take on this issue, but you were faster! Your implementation is exactly what I had in mind, so thank you for contributing with the improvement. ☺️

Out of curiosity: can't you use the original function here instead of duplicating it?

@hoc081098 The optimization is really great but we have an issue as, the returned result can randomly not be in the same order as the module list.

flatten(m1, m2) can result in <m1,m2> or <m1,m2> which is breaking capacity to overload a definition, given the module order

DefinitionOverrideTest is failing on branch 3.6.0

@arnaudgiuliani
I think because I have used HashSet, I will create a PR to fix it

I think so, linkedhashmap is better than not.
