openkal-linux 0.7.1 and openkal-macos 0.6.1 - #283
Merged
Conversation
Both fix one defect. `kal_timeout_read` and `kal_timeout_write` decoded a borrowed `kal_stream` handle with the decoder for an owned one. A bare descriptor N has exactly the shape of a packed handle naming N-1, so the decode succeeded and the wait was performed upon N-1 while the transfer was performed upon N. Reported through openkal-musl in mcpplibs/openkal-linux#13 as `std::filesystem::copy_file` answering `Resource temporarily unavailable` for two ordinary files. openkal-macos 0.6.1 also runs this package's own `tests/` for the first time: no workflow had ever invoked them. Measured before this commit: both CN mirror assets return 200 and their sha256 is identical to the GitHub tag tarball named beside them.

Two backends, one defect.
kal_timeout_readandkal_timeout_writedecoded a borrowedkal_streamhandle withokl::unpack/okm::unpack, which is the decoder for an owned handle. Those backends pack an owned handle as(generation << 32) | (fd + 1), so a bare descriptorNhas exactly the shape of a packed handle namingN-1and the decode succeeded.

Every CN asset was fetched and hashed rather than assumed, because the mirror tool has reported
uploadedfor an object that afterwards answered 404.Locally:
check_mirror_urls,check_package_name,check_cross_package_refs,check_platform_version_parityandcheck_duplicate_versionsall pass.Both descriptors carry three platform tables and the new version is added to all three, as the existing entries are.
