v0.11.0

0.11.0 - 2024-03-27

Added

• support for Go 1.21 and newer. See #417.
• support for rules_go 0.42.0 and newer. See #422.
• nixpkgs_flake_package now works even when the experimental features nix-command and flakes are disabled. See #465.
• sigtool and codesign for the cc toolchain on macOS. See #489.

Changed

• nixpkgs_flake_package now only copies the directory containing the nix_flake_file, including any subdirectories, to the nix store. nixpkgs_flake_package would previously copy the entire containing Git repository to the nix store if nix_flake_file was contained in a Git repository. This is achieved via nix' path: syntax. This is a breaking change for nix_flake_files inside a subdirectory of a Git repository that references a path outside its subdirectory. See #450.

Fixed

• Build failure when using -fsanitize=address with the cc toolchain. See #437.
• The Go toolchain now disables the GOEXPERIMENT CoverageRedesign following the example of rules_go and. See #440.
• NixOS dynamic loader issue for Java tools like ijar and singlejar. See #451.
• nixpkgs_cc_configuren with Bazel 7 was causing a syntax error at '%': expected expression" because of a missingtemplate tsubstitution for conly_flags. See #466.
• Build failures with linker errors caused by a missing -F${SystemConfiguration}/Library/Frameworks cc command line option. See #475.
• Processes getting killed on macOS during linking caused by using some tools form darwin.cctools instead of stdenv.cc. See #479.

Removed

• Python 2 support has been removed. See #486.

Changed

        name = "bazel-nixpkgs-cc";
        paths = [ cumstom-cc ];
        pathsToLink = [ "/bin" ];

        };
      }

Release 0.8.0

0.8.0 - 2021-02-11

Added

• Bazel Skylib is now included as a dependency on rules_nixpkgs_dependencies.
  See #125.
• nixpkgs_python_configure now exposes the quiet attribute for the
  underlying nispkgs_package.
  See #131.
• The default BUILD file of nixpkgs_package now finds more kinds of C/C++
  header files in the include target.
  See #137.

Changed

• The implementation of nixpkgs_cc_configure has been replaced by a more
  hermetic version that no longer uses Bazel's builtin autodection toolchain
  under the hood. The previous behavior is now available under the name
  nixpkgs_cc_configure_deprecated, if required.
  See #128.
• The values in the nixopts attribute to nixpkgs_package are now subject to
  location expansion. Any instance of $(location LABEL) in the nixopts
  attribute will be expanded to the file path of the file referenced by
  LABEL. To pass a plain $ to Nix it must be escaped as $$.
  See #132.

Deprecated

• The old implementation of nixpkgs_cc_configure, now available under the
  name nixpkgs_cc_configure_deprecated, has been marked as deprecated in
  favor of nixpkgs_cc_configure and will be replaced by it in future.
  See #128.

Fixed

• Incorrect label contruction for Nix file dependencies.
  See #124.

Release 0.7.0

Added

• Define rules_nixpkgs_dependencies in //nixpkgs:repositories.bzl.
• Define nixpkgs_go_configure in //nixpkgs:toolchains/go.bzl
• nixpkgs_package now has a quiet attribute.

Changed

• The constraint value for targets to detect whether Nix is available
  on the current platform is now called
  @//nixpkgs/constraints:support_nix. The associated constraint
  setting is @//nixpkgs/constraints:nix. The old constraint
  @//nixpkgs/constraints:nixpkgs constraint setting is still
  available. But it is highly recommended to migrate to the new
  constraint setting, and update platform definitions accordingly.
  This is a breaking change for users of nixpkgs_python_configure.
• Show Nix output by default, like in releases prior to v0.6.

Fixed

• nixpkgs_local_repository now correctly invalidates the cache when
  Nix source files change. See
  #123.

Release 0.6.0

0.6.0 - 2019-11-14

Added

• Check nix_file_deps and fail on undeclared dependencies (breaking change).
  See #76 and #86.
• Define a nixpkgs platform constraint. See #97.
• Define nixpkgs_python_configure. See #97.
• Define nixpkgs_sh_posix_configure to generate rules_sh POSIX
  toolchain. See #95.

Changed

• Hide Nix output, following Bazel best practices for a quiet build.
• Disable implicit nixpkgs configuration loading (breaking change).
  See #83.

Fixed

• Improve distributed caching by not leaking user specific Bazel cache
  directory, see #67.
