Autocxx Versions Save

What's Changed

• Treat C++ warnings as fatal within the test suite, revealing a problem that needed to be fixed in our generated code...
• Fix unnecessary std::move by @adetaylor in https://github.com/google/autocxx/pull/1048

Full Changelog: https://github.com/google/autocxx/compare/v0.21.1...v0.21.2

What's Changed

Significant improvement (though some corner cases wouldn't surprise me): where possible, treat incomprehensible typedefs as opaque types by @adetaylor in https://github.com/google/autocxx/pull/1035. Previously if we encountered a type that bindgen couldn't fully handle, we ignored that type plus any typedefs that depended upon it. Now, we still discard the type - but typedefs should continue to be somewhat usable.

Bug fixes

Internal and testing changes

• Modularize directive handling. by @adetaylor in https://github.com/google/autocxx/pull/1032
• Add test for base class destructors getting called. by @adetaylor in https://github.com/google/autocxx/pull/1041

Full Changelog: https://github.com/google/autocxx/compare/v0.21.0...v0.21.1

What's Changed

Major breaking change:

• Functions which return (non-POD) values no longer return a UniquePtr. Instead they return an impl New, so you can emplace them on the stack or in a Box if you prefer. If in doubt, simply append .within_unique_ptr() to go back to the old behavior. (https://github.com/google/autocxx/pull/998)
• Function calls which take rvalue reference parameters (Thingy&&) are now supported (https://github.com/google/autocxx/pull/821)

Bug fixes:

• Fix for mdbook off-by-one test ID. by @adetaylor in https://github.com/google/autocxx/pull/1028

Full Changelog: https://github.com/google/autocxx/compare/v0.20.1...v0.21.0

What's Changed

• Bug fix to stop important error messages disappearing (thanks to @testforvln for the report) - in https://github.com/google/autocxx/pull/1021
• Slightly more flexibility when storing C++ objects in Rust boxes:
  • Cease to need MakeCppStorage to put something in a Box by @adetaylor in https://github.com/google/autocxx/pull/1022
  • impl ValueParam for Pin<Box<T>> by @adetaylor in https://github.com/google/autocxx/pull/1024

Various internal tidyings.

• Outdent a test. by @adetaylor in https://github.com/google/autocxx/pull/1023
• Fix destructor trait safety. by @adetaylor in https://github.com/google/autocxx/pull/1025
• Unsafe dialect by @adetaylor in https://github.com/google/autocxx/pull/1026
• Upgrade to 0.20.1. by @adetaylor in https://github.com/google/autocxx/pull/1027

The next release is likely to be a significant compatibility break as we land a major part of #379.

Full Changelog: https://github.com/google/autocxx/compare/v0.20.0...v0.20.1

What's Changed

New features

• Support writing depfiles from autocxx_gen by @adetaylor in https://github.com/google/autocxx/pull/1012
• Basic support for extern_cpp_type! by @adetaylor in https://github.com/google/autocxx/pull/1008. This allows one set of include_cpp! bindings to delegate a type to another set obindings.

Boring but breaking change

• Split the Within trait into two by @adetaylor in https://github.com/google/autocxx/pull/1013

Bugfixes and documentation

This version includes a lot of restructuring with no intentional functional change, as prep work for eventually landing the next bit of #379.

• Rewrite constructor chapter of book. by @adetaylor in https://github.com/google/autocxx/pull/1000
• Publish integration tests by @adetaylor in https://github.com/google/autocxx/pull/1001
• Switch tests away from deprecated ::make_unique(). by @adetaylor in https://github.com/google/autocxx/pull/1003
• Restructure codegen_rs/fun/mod.rs by @adetaylor in https://github.com/google/autocxx/pull/1002
• Show autocxx_build::Builder::new in docs by @Xaeroxe in https://github.com/google/autocxx/pull/1004

New Contributors

• @Xaeroxe made their first contribution in https://github.com/google/autocxx/pull/1004

Full Changelog: https://github.com/google/autocxx/compare/v0.19.1...v0.20.0

What's Changed

• This release deprecates the make_unique() functions that were previously created for each constructor, and instead introduces a new Within trait. This will later become the only way of using constructors. (@adetaylor in https://github.com/google/autocxx/pull/997)

Testing improvements

• Do a test run under ASAN on github CI by @adetaylor in https://github.com/google/autocxx/pull/993 (thanks also to @philipcraig )
• Add tests for gen by @bsilver8192 in https://github.com/google/autocxx/pull/913

Full Changelog: https://github.com/google/autocxx/compare/v0.19.0...v0.19.1

Improvements

• Don't spam stderr so much by @adetaylor in https://github.com/google/autocxx/pull/985
• Use miette for nicer syntax errors by @adetaylor in https://github.com/google/autocxx/pull/980. This also removes some long-deprecated functions, so you may need to update your build.rs files.
• Recognize size_t as usize by @adetaylor in https://github.com/google/autocxx/pull/986
• Support array fields within structs by @yshui (thanks!) in https://github.com/google/autocxx/pull/969

Bug fixes

• Fix use of &str in generated C++ code by @adetaylor in https://github.com/google/autocxx/pull/984
• Ignore constructors taking extra default parameters by @adetaylor in https://github.com/google/autocxx/pull/983
• Fix erroneous allocation sizes when using moveit::new::New by @adetaylor in https://github.com/google/autocxx/pull/991
• Fix problem with methods beginning with their class name by @adetaylor in https://github.com/google/autocxx/pull/992

Miscellaneous

• Add test for moving out of UP by @adetaylor in https://github.com/google/autocxx/pull/973

Full Changelog: https://github.com/google/autocxx/compare/v0.18.0...v0.19.0

What's Changed

• Fix a problem when used with the most recent version of syn by @adetaylor in https://github.com/google/autocxx/pull/971
• Roll to moveit 0.5.0. by @adetaylor in https://github.com/google/autocxx/pull/970. This change allows you to move out of a UniquePtr, e.g.

let xyz: UniquePtr<Foo> = ...;
moveit! {
  let stack_xyz = autocxx::moveit::new::mov(xyz);
}

This is technically a breaking change though I doubt anyone much is using the MoveRef trait a lot.
