System libraries versions (grpc)

[gabriel-doriath-dohler]

Is there a way to retrieve the correct (and tested) versions for system libraries such as grpc?
Currently, it can be extracted using cargo metadata and sed 's/^.*+//;s/-.*$//', as the grpcio-sys version includes the grpc version.
Will this be stable or will the naming convention change?

Why do you want that library?

I'm using pkg-config and GRPCIO_SYS_USE_PKG_CONFIG=1, so I need to know the correct grpc version.
Currently I'm using the grpc version from the grpcio-sys version.
For example, I'm using grpc 1.44.0 for grpcio-sys v0.10.3+1.44.0-patched.

If the naming convention for grpcio-sys versions change, my regexpr will not work. So, will the convention change or do you provide any other stable way to get the correct grpc version?

Currently TiKV's version include a patch that is not merged into upstream. tikv/grpc@38a9cd9. So use customized library may miss the functionality. I would not say the format of grpcio-sys version name is reliable. But I don't see it will change in the near future. The format is {grpcio-sys version}+{grpc version}[-patched[.1]. -patched part means whether we have included unreleased patch based on the grpc version. -patched.1 means more patches than -patched are included in the grpc.

Thanks a lot! Where can I get a list of all patches that are not merged upstream, so that I can apply them?

Currently there is only one functionality difference. You can get what's changed by git diff {grpcio-sys version}.
