libnbd-release-notes-1.12 - release notes for libnbd 1.12
These are the release notes for libnbd stable release 1.12. This describes the major changes since 1.10.
libnbd 1.12.0 was released on 24 February 2022.
See the full announcement here: https://listman.redhat.com/archives/libguestfs/2022-February/msg00104.html
If you find a security issue, please read SECURITY in the source (online here: https://gitlab.com/nbdkit/libnbd/blob/master/SECURITY). To find out about previous security issues in libnbd, see libnbd-security(3).
Error messages about incorrect URIs in nbd_connect_uri(3) have been improved to make common mistakes clearer for the user.
New syntax: "nbdinfo [ CMD ... ]" allowing you to query the properties of an NBD server directly.
nbdcopy(1) new --queue-size option to control the maximum size of the internal buffer (Nir Soffer).
nbdcopy(1) now names the source and destination handles to make it easier to understand debug output.
Adopt libvirt-ci's ci/gitlab.yml (Martin Kletzander).
Fix the OCaml extents example (thanks Laszlo Ersek).
Golang benchmarks were added to the test suite (Nir Soffer).
The large tests/errors.c test was split into about a dozen separate tests. Also this adds a new test for checking server-side block size constraint error policy which was missing before.
New OCaml "NBD.with_handle" helper which ensures that "NBD.close" is always called even if the inner code throws an exception.
The OCaml bindings now consistently use the correct types for buffer sizes everywhere (Laszlo Ersek).
Several improvements and fixes to the golang bindings and tests. The golang bindings have been relicensed to LGPLv2+ like the rest of the library and are now published as a golang module at https://libguestfs.org/libnbd (Nir Soffer).
The Python bindings no longer crash if you pass "None" in place of a buffer parameter. In addition some memory leaks were fixed (Eric Blake).
Various memory leaks have been fixed when using the optional strict_mode settings (Eric Blake).
The performance of the internal vector library has been improved greatly and overflow is now handled correctly (Nir Soffer, Laszlo Ersek and Eric Blake).
Add "simple_copy" and "aio_copy" Golang examples (Nir Soffer).
Error handling was reviewed and fixed across many of the example programs and documentation (Eric Blake, Nir Soffer).
Simplify and optimize handling of the extents callback in Golang (Nir Soffer).
Golang AioBuffer was enhanced, making it safer to use, faster and adding documentation (Nir Soffer).
Document the limits on lengths and sizes of parameters to various APIs (Eric Blake).
You can now build programs that use the OCaml bindings of libnbd against the libnbd build directory instead of requiring libnbd to be installed (Laszlo Ersek).
Compatibility with OCaml 4.13.
Line locations in the state machine should be more accurate when stepping through with a debugger like gdb.
.editorconfig file can be used to help code formatting, see https://editorconfig.org/ (Nir Soffer, Eric Blake).
"MIN" and "MAX" macros can be nested (thanks Eric Blake).
