openkal-llvm-runtime 0.5.0

[Sunrisepeak]

Completes the chain begun in #283 (openkal-linux 0.7.1, openkal-macos 0.6.1), #284 (openkal-musl 0.8.0) and #286 (openkal-musl 0.9.0). A consumer names this one line and gets all of it:

[dependencies]
openkal-llvm-runtime = "0.5.0"

What a program above it gets

• std::filesystem::copy_file reported Resource temporarily unavailable for two ordinary files. libc++ opens a copy's source with O_NONBLOCK, which is meaningless for a regular file on a kernel; openkal-musl routes that through the bounded-transfer path, and the backends' kal_timeout_read decoded a borrowed kal_stream handle with the decoder for an owned one — waiting upon the descriptor below the one it then transferred upon.
• std::filesystem::resize_file worked for no path at all, because libc++ expresses it as the name-shaped truncate and only ftruncate was answered.
• A build can now state its own version. OPENKAL_MUSL_TRACE=enosys names it before the program runs and whether or not anything is missing; uname's release field carries it too. Both were absent, and two rounds of ENOSYS for fork/pipe/socket/chmod/symlink/copy_file_range blocks POSIX-style CLI workloads; one startup path jumps through a NULL stub openkal-linux#13 were answered against the wrong version because of it.

Fetched back from the published CN URL, hashed against the GitHub tag tarball, and opened as an archive.

And the chain itself was verified through the index rather than through working trees — every repository in this family substitutes working trees for its dependencies in CI, so none of those runs examines the index entry, the archive, its hash or the resolved graph:

openkal-musl = "0.7.0"      (index+mcpplibs@0.7.0 -> openkal-linux 0.7.0)
  note: 1 of 16 pipes reported readable
  FAIL: a pipe with a byte in it is reported readable

openkal-musl = "0.8.0"      (index+mcpplibs@0.7.1 -> openkal-linux 0.7.1)
  ok: truncate(2) by name
  ok: the length set by name is reported
  ok: a pipe with a byte in it is reported readable

Locally: check_mirror_urls, check_package_name, check_cross_package_refs, check_platform_version_parity, check_duplicate_versions all pass. Added to all three platform tables, newest first, as this descriptor orders them.
