Fix #247 ensure binary compatibility from now #248
Conversation
I have force-pushed just to update some comments |
@lrytz I haven't looked at the fnGen stuff before. but this certainly looks plausible, and we should get a release out before much longer, to correct the bincompat breakage. any objection to just merging this? |

Background
FunctionConverters
is generated by an internalfnGen
sbt project that use scala-compiler & scala-reflect to generate converter for all interfaces injava.util.function
package.Problem
fnGen
is not reliable. It produce different code on different run [1]In #211, @SethTisue have to add some
ProblemFilters.exclude
.But, as describing in #247, the mima Problem should not be filtered out because it will cause real binary incompatible error in runtime.
Solution by this PR
fnGen
: Don't use scala-compiler & scala-reflectThe generated code by the new
fnGen
implementation is exactly same as the generated code by the oldfnGen
on my machine. (somehow, the oldfnGen
is reliable in my machine :D)You can and should verify that in your machine too.
[1]
sbt sources
on CI (on my fork) and check the generated code, I found that the output is different in some CI jobs / runs.FunctionConverters
not only between versions but also in the same version with different scala cross build (ex.._2.12-1.0.1.jar
vs.._2.12-1.0.1.jar
). See this CI job that run mima against all released version from 0.9.1 and only v0.9.1 for scala 2.12 is mima check passed.
