🦋 nbdkit-release-notes-1.36 💖

okay bestie, welcome to the NBDKIT release notes page for nbdkit 1.36 — yes, the manual is literally called nbdkit-release-notes-1.36, and yes, it's exactly as iconic as it sounds. sit down, grab a lil snack, we're going through everything. 🍓

✨ NAME ✨

nbdkit-release-notes-1.36 — the release notes for nbdkit 1.36. that's it, that's the name, slay. 💅

🌸 DESCRIPTION 🌸

These are the release notes for the nbdkit stable release 1.36, and they're describing the major changes since 1.34. glow-up era fr fr. 🫶

nbdkit 1.36.0 was released on 27 September 2023. mark your calendars, it's giving birthday energy. 🎂

🔒 Security 🔒

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

All past security issues, plus the info on how to report new ones, live in nbdkit-security(1). iykyk. 🛡️

🧩 Plugins 🧩

  • New nbdkit-ones-plugin(1) — makes a fully allocated disk containing all 0xff (all ones), or honestly any other byte of your choice. pick your fighter. 👑
  • nbdkit-curl-plugin(1) now uses a curl "multi" interface. this enables much better performance, and also lets the curl plugin handle requests in parallel. multitasking queen behavior. 💅 the curl plugin now falls back to making a "GET" request to get the size of the remote file for certain servers which do not support "HEAD" requests. and it adds new options: "ipresolve" (force IPv4 or IPv6), "resolve" (force a particular IP address), -D curl.times=1 (print detailed timing stats), and -D curl.verbose.ids=1 (display connection and transfer IDs). so many lil treats. 🎀
  • nbdkit-memory-plugin(1) now uses a read-write lock to protect internal structures, which results in improved performance for mostly read workloads. lowkey a glow-up. 🌈
  • nbdkit-data-plugin(1) now has more optimizations. more. optimizations. periodt. 🔥
  • nbdkit-file-plugin(1) now supports 4k sector sizes on Windows (Brian Carnes). 🪟

🧚 Filters 🧚

  • New nbdkit-evil-filter(1) — adds random but consistent data corruption to the underlying plugin. chaotic but make it reproducible, honestly iconic. 😈
  • New nbdkit-qcow2dec-filter(1) — can decode qcow2 files (but not write to them). read-only girly. 🙈
  • nbdkit-ip-filter(1) can now filter by client SELinux label.
  • nbdkit-partition-filter(1) now supports 4k sector sizes (Brian Carnes).
  • nbdkit-retry-request-filter(1) allows the "get_size" operation to be retried. second chances are a love language. 💜
  • nbdkit-tar-filter(1) adds a new "tar-limit" parameter, which can be used to make sure the filter does not read indefinite amounts of input when opening the tar file. boundaries, bestie. 🚧
  • Filters can now append their own output to nbdkit --dump-plugin output. main character filters fr. 👑

🦀 Language bindings 🦀

  • Rust bindings add support for "after_fork", "block_size", "nbdkit_debug", "nbdkit_is_tls", "nbdkit_parse_size", "nbdkit_parse_bool" and "nbdkit_parse_probability". the "open" method can now return an error — and heads up, this is not backwards compatible and requires a small source code change to Rust plugins. (Thanks Alan Somers) 🫶
  • nbdkit-ocaml-plugin(3) now supports OCaml 5.
  • OCaml bindings add support for "nbdkit_stdio_safe", "nbdkit_is_tls", "nbdkit_peer_name" and "nbdkit_peer_security_context".
  • nbdkit-perl-plugin(3) now supports Perl 5.38.
  • Shell script plugins (nbdkit-sh-plugin(3)) may now ignore stdin in their "pwrite" method, whereas previously it was required to read and discard stdin along error paths (thanks Eric Blake). growth. 🌱

🖥️ Server 🖥️

  • When using the --run option, the default is now to use a private Unix domain socket (as if -U - was specified), whereas in nbdkit ≤ 1.34 the default was to open a TCP port. the new default reflects the most common and safest way to use the --run option. you can find out if nbdkit has the new behaviour by checking nbdkit --dump-config and looking for run_default_socket=Unix in the output. okay but the safest option being the default?? we love character development. 💖
  • Debug strings containing control codes and other non-printable characters are now escaped properly. no more unhinged terminal chaos. 💀
  • New flag -D nbdkit.environ=1 can be used to dump the server environment in debug output. spill the env, queen. ☕

🛠️ API 🛠️

  • New "nbdkit_parse_probability" function — can be used to parse probabilities in various formats, like "10%" or "1:10". math girlies rise. 📊
  • New "nbdkit_peer_security_context" function — returns the security context (usually SELinux label) of the client. know your audience fr. 👀

🐛 Bug fixes 🐛

  • Fixed a long-standing double-free in nbdkit-file-plugin(1) when the client closes the connection during negotiation (thanks Eric Blake). that bug was lowkey ancient, rest in peace bestie. ⚰️
  • nbdkit-file-plugin now has improved error messages when you try to open a file with an empty name (""). no more cryptic nonsense. 💅

📚 Documentation 📚

  • Miscellaneous documentation improvements for Windows (Brian Carnes).
  • Fuzzing instructions updated for Clang 17, AFL++ 4.08c.

🧪 Tests 🧪

  • Ongoing CI maintenance and fixes (Laszlo Ersek, Eric Blake). the grind never stops. ☕
  • Many fixes in the test suite for MinGW and Wine.
  • Several internal consistency checks were added to the test suite, to ensure, for example, that we always use "requires_run" when the test uses the nbdkit --run option. accountability era. ✨

🏗️ Build 🏗️

  • Optionally "zlib-ng" can be used (instead of "zlib") for faster decompression in various places. speed. 🏎️
  • No longer link with msvcrt on Windows.
  • "awk" is a build requirement. it was implicitly required before (because it is needed by the "./configure" script generated by autoconf), but now the dependency is explicit (Eric Blake). making it official. 💍

🔧 Internals 🔧

  • "podwrapper" has a new --replace parameter which makes it easier to use "AC_SUBST"-substitutions in documentation. quality of life upgrade, we stan. 🎀
