✨ NAME ✨

nbdkit-release-notes-1.38 — the release notes for nbdkit 1.38, no cap.

🌸 DESCRIPTION 🌸

These are the release notes for nbdkit stable release 1.38, and they spill all the major changes since 1.36. main character energy fr fr.

nbdkit 1.38.0 dropped on 5 April 2024. mark your calendars. 📅

🔒 Security

No security issues were found in this release. we love a clean vibe check. ✨

All past security issues and info on how to report new ones can be found in nbdkit-security(1). iykyk.

🧩 Plugins

New nbdkit-gcs-plugin(1) providing support for Google Cloud Storage (Mykola Ivanets). new plugin just dropped. 👑

nbdkit-data-plugin(1), nbdkit-memory-plugin(1), nbdkit-floppy-plugin(1), nbdkit-iso-plugin(1), nbdkit-sparse-random-plugin(1) and nbdkit-torrent-plugin(1) all now advertise suitable minimum, preferred and maximum block sizes, which means clients should be able to access them more efficiently. efficiency? slay. 🦋

nbdkit-vddk-plugin(1) now supports VDDK up to version 8.0.2.1. glow up. 💅

nbdkit-S3-plugin(1) now reads sensitive tokens as passwords, allowing more flexibility on how to safely pass them to nbdkit. safe AND flexible, we love to see it. 🔐

🎀 Filters

New nbdkit-readonly-filter(1) which allows more fine-grained control over whether a plugin is read-only (and also to change it at runtime) compared to the normal nbdkit -r command line option. so you get more control than -r, and you can flip it while it's running. iconic.

🌈 Language bindings

nbdkit-python-plugin(3) adds bindings for nbdkit.is_tls, nbdkit.stdio_safe, nbdkit.nanosleep, nbdkit.peer_pid, nbdkit.peer_uid, nbdkit.peer_gid, nbdkit.peer_security_context, nbdkit.read_password. so many new toys bestie. 🐍

nbdkit-ocaml-plugin(3) implements zero-copy pread and pwrite calls. ⚠️ heads up: this change is not backwards compatible for OCaml plugin code. (Thanks Nicolas Ojeda Bar, Anil Madhavapeddy, Simon Cruanes). 🐫

nbdkit-ocaml-plugin also adds extra OCaml version information to --dump-plugin output; and adds an example of how to use debug flags.

nbdkit-rust-plugin(3) minimum Rust version (MSRV) increased to 1.63.0. Various issues found by clippy have been fixed (Alan Somers). 🦀

🖥️ Server

New --no-meta-contexts (--no-mc) option which stops the server from advertising metadata contexts, improving interoperability testing (Eric Blake). sometimes the move is to say less, periodt.

nbdkit --dump-plugin outputs additional fields: The internal soext, either so or dll so you can tell what plugin/filter extension the server is looking for. The max_api_version is the maximum plugin API version supported. receipts, but for the server. 🧾

🐛 Bug fixes

Fix compilation with GCC 14 (Florian Weimer). 🙏

Fix the default block size exposed by nbdkit-S3-plugin(1), fix the zero callback, and other bug fixes (Mykola Ivanets).

nbdkit-luks-filter(1) could enter an infinite loop in some error cases (Wilko Nienhaus). 😭 not the infinite loop.

Several plugins would crash or behave strangely if no parameters were passed. These have been fixed and a regression test added. no parameters, no drama. 💀

📚 Documentation

Update fio benchmarking documentation (Eric Blake).

Add example of how to export a variable to --run subcommands (Eric Blake). very useful, very demure. 🎀

🧪 Tests

Fix Cirros CI tests (Peter Krempa).

🛠️ Build

bash ≥ 4 is required. (This was always true, but now the ./configure script checks it.) the vibe was always there, now it's official.

You can now use both environment variables NBDKIT_VALGRIND=1 NBDKIT_GDB=1 together to run valgrind and gdbserver, in order to debug valgrinded nbdkit and plugins. double the debugging, double the fun. 🔥

🔮 Internals

Important internal structs now contain magic values which are checked by optional assertions, improving type safety. magic values?? it's giving wizardry, honestly. ✨
