rust2rpm

Version 24.0.0
==============

This release contains large internal changes to support more use cases and
Rust projects that use new syntax for feature dependencies in their Cargo.toml
metadata. The functionality for translating between cargo and RPM metadata
and the RPM macros and dependency generators were moved to separate projects.

Additionally, the versioning scheme of rust2rpm has changed to allow for minor
or bugfix-only releases that do not change spec file rendering and which don't
require bumping the version number in the "# Generated by rust2rpm XX" header.

Added:

- Support for building non-crate projects that use cargo workspaces was added.
- The default Rust compiler flags now support conditionally building Rust code
  with frame pointers (only enabled on Fedora 38+ on x86_64 and aarch64).
- New syntax for cargo feature dependencies (`dep:foo`) is now supported when
  creating "remove foreign dependencies" patches.
- Rust crates that exclusively build shared libraries (`cdylib` targets) are now
  (partially) supported by rust2rpm and no longer cause crashes.

Changed:

- Large parts of the project were refactored, modernized, reorganized into
  smaller files, and updated with type annotations.
- The deprecated `requests.compat` module is no longer used, as all methods
  used by rust2rpm have been part of the Python standard library for years.

Fixed:

- Logic for determining the list of feature subpackages was fixed. The
  assumptions in the previous implementation were broken for crates that use
  Rust 1.60+ syntax for feature dependencies.
- Logic for sorting binaries in %files lists was fixed to not cause crashes if
  there are two or more binaries.
- Logic in the cfg-expression evaluation was fixed and no longer produces
  architecture-specific patches.
- Logic for checking for the existence of a dist-git repo for the current
  package was fixed to account for URL formatting issues.
- Files that are read when trying to detect the "host linux distribution" are
  now closed correctly.
- Test fixtures were added for the year 2023.

Removed:

- The cargo-inspector executable was removed. It is no longer used by Rust RPM
  macros.
- Files for RPM macros and dependency generators were moved into a separate
  project (rust-packaging).

Version 23
==========

Added:

- New macros for collecting license information for all crates that are
  statically linked into a Rust binary (`%cargo_license` and
  `%cargo_license_summary`).
- Add support for specifying "testrequires" in rust2rpm.conf. These work similar
  to "buildrequires", but the specified dependencies will be wrapped in an
  `%if %{with check}` conditional in the generated spec file. This can be used
  to specify BuildRequires that are only needed when running a crate's test
  suite, but which are not necessary to build the crate itself.

Changed:

- The list of binaries in %files is now consistently sorted in generated spec
  files (this only affects crates that build more than one binary, of course).
- Fall back to the latest pre-release if there are no stable releases (or if
  all previously published stable released have been yanked).
- Dropped `ExclusiveArch: %{rust_arches}` when generating spec files for Fedora.
  RPM itself will start to depend on Rust components, so Rust will by definition
  need to be available on all architectures that are supported by Fedora.
- Replaced `i686` with the `%{ix86}` macro in `%{rust_arches}`.

Fixed:

- Ensure that rust2rpm doesn't auto-generate architecture-dependent patches.
- Ensure both automatically generated and manually written patches affect spec
  file generation (i.e. feature subpackages).
- Fix evaluation of cfg-expressions that contain the new "wasm64" target.
- Only remove target-specific dependencies from feature dependencies if they
  are optional.
- The logic for replacing the current version of rust2rpm when comparing spec
  output in tests has been fixed for OpenSUSE spec templates.

Version 22
==========

This release comes with lots of improvements, bug fixes, and new features, but
also drops support for Python versions older than 3.10.

Added:

- Add macros to allow overriding default Rust compiler flags without needing to
  manually invoke sed: %rustflags_opt_level, %rustflags_debuginfo,
  %rustflags_codegen_units (PR#182 / @zbyszek)
- Add a new rust2rpm.conf setting that mirrors the "--all-features" CLI
  argument of rust2rpm (PR#191 / @decathorpe)
- Add support for running rust2rpm without an explicit crate name argument, and
  use heuristics (value of the %crate macro in an existing spec file, or the
  name of the current directory) as fallback values (PR#197 / @zbyszek)
- Add a parser and evaluation logic for "cfg"-expressions and automatically
  generate a Cargo.toml patch that removes "foreign" dependencies
  (PR#183 / @zbyszek)
- Add CC-PDDC ("Creative Commons Public Domain Dedication and Certification")
  to the list of accepted licenses (PR#203 / @yizhengxie)
- Added simple logger functionality and print messages to stderr to ensure the
  "--stdout" mode of rust2rpm continues to work (@decathorpe).

Changed:

- Change the default name of the rust2rpm configuration file to "rust2rpm.conf",
  and migrate existing ".rust2rpm.conf" and "_rust2rpm.conf" files
  (PR#189 / @decathorpe)
- Dropped unnecessary numbering of patches in spec files generated by rust2rpm
  (PR#196 / @gotmax23)
- Dropped translation from SPDX license expressions to Fedora / Callaway
  notation when targeting Fedora or EPEL (PR#195 / @zbyszek)
- Apply consistent formatting for %license and %doc files for binary packages
  and -devel packages (PR#197 / @zbyszek)
- Skip pre-release versions when running rust2rpm without an explicit version
  argument (PR#197 / @zbyszek)
- Change the warning messages that are printed after the "existence check" of
  rust2rpm succeeds to take compat packages into account (PR#199 / @decathorpe)
- Split rust2rpm package into "core" functionality without third-party python
  dependencies, which can be used by cargo-inspector and RPM macros
  (PR#204 / @decathorpe)
- Ported rust2rpm packaging to declarative configuration with setup.cfg and
  pyproject.toml (PR#207 / @decathorpe)
- Enforced a consistent code formatting standard with black (@decathorpe).

Fixed:

- Various fixes for the automatic detection of rpmautospec usage in existing
  spec files and the "--rpmautospec" and "--no-rpmautospec" CLI arguments
  (PR#190, PR#195 / @zbyszek, @andersblomdell)
- Fix building with Rust 1.62+, which now fails when re-packaging sources from
  crates.io (PR#194 / @decathorpe)
- Fixed the "existence check" when running rust2rpm by requesting the correct
  URL (PR#199 / @decathorpe)
- Fixed tox settings for refactored tests and updated list of supported Python
  versions (PR#208 / @decathorpe)
