Hi @headius . Thank you for the quick response. The constants generated match the bitmasks we ended up hardcoding into our application for
O_DIRECT, so the values have been tested in situ.A few comments/questions (somewhat) related to this PR:
The
regen:platformresulted in updates to AddressFamily.java and ProtocolFamily.java on Linux x86_64 and aarch64. Since they aren't directly related to this change, I left them out. Should I include them? Should I submit a separate PR?When I run on Apple M1 (
uname -sm -> Darwin arm64), it creates a new directorysrc/main/java/jnr/constants/platform/darwin/x86_64/. I was expecting it to generatedarwin/aarch64. I assume this is a quirk of the M1.O_DIRECTisn't defined on Darwin, so it doesn't matter for this PR anyway.When I ran
rake regen:lplatformon Linux x86_64, it creates a new foldersrc/main/java/jnr/constants/platform/linux/x86_64/, which seems correct. Runningrake regen:platformupdates ``src/main/java/jnr/constants/platform/linux/`. Is the use of the latter a convention?
