* Resynchronize absl/functional/CMakeLists.txt with BUILD.bazelGravatar Benjamin Barenblat2024-05-08
| | | | | | | | | | overload_test needs some extra dependencies to build when absl::variant is not an alias for std::variant; these dependencies are listed in absl/functional/BUILD.bazel but not in absl/functional/CMakeLists.txt. Copy dependencies from BUILD.bazel to CMakeLists.txt. PiperOrigin-RevId: 631845552 Change-Id: I63f53323b28aff36530be645b312e94b24475f53

* `convert_test`: Extract loop over tested floats from helper functionGravatar Dino Radakovic2024-05-06
| | | | | | | | | | This change is a step towards simplifying `TestWithMultipleFormatsHelper` to the point where we'll be able to handle special cases (e.g. apple's handling of nan) by changing which inputs are fed into the helper, instead of skipping them within the helper and not testing them at all. Extracting the loop also improves readability by reducing indentation. PiperOrigin-RevId: 631038465 Change-Id: I8b2458539d9d276093d8e7b5f373efba6a33800c

| | | | | | | | | | | | | | STRIP_LOG is enabled When `STRIP_LOG` is off, the internal variable `absl_log_internal_check_op_result` is passed to `absl::log_internal::LogMessageFatal()` and used in the failure message. When `STRIP_LOG` is on, the variable is truly unused. Applying a `ABSL_ATTRIBUTE_UNUSED` on the variable triggers `-Wused-but-marked-unused` when `STRIP_LOG` is off, not applying the attribute triggers `-Wunused-but-set-variable` when `STRIP_LOG` is on. Define a new internal macro `ABSL_LOG_INTERNAL_ATTRIBUTE_UNUSED_IF_STRIP_LOG` that evaluates to `ABSL_ATTRIBUTE_UNUSED` when `STRIP_LOG` is on and nothing when `STRIP_LOG` is off to address both of these scenarios.

* Add internal traits for lifetimebound detectionGravatar Abseil Team2024-04-01
| | | | | | | | | | | | | | | | | | | | | | | | This will helps compilers that understand `ABSL_ATTRIBUTE_LIFETIME_BOUND` flag constructs such as `absl::StatusOr<std::string_view> str = std::string(...)` as error-prone. For standard types, this is done via specializing the type traits. For all other types, this is done by detecting the presence of a Boolean member trait such as: `using absl_internal_is_view = std::true_type;` in the type. This is purely intended as a safety feature, and the values of these traits (even if wrong!) must NOT be depended on for correct behavior. Furthermore, only high-value types (such as `absl::StatusOr`) are the intended users here. Do not declare or use these traits on arbitrary types that are unlikely to be misused. Do not depend on any of these to be stable, as they not (yet) public APIs. Moreover, the trait declarations and mechanisms are all subject to change. (For example, if `[[clang::lifetimebound]]` becomes possible to detect directly, the traits may need to be altered to utilize that, and distinguish between assignments and constructions.) Should these or similar APIs be made public at a later point, the detection mechanisms may be altered quickly, and may (either loudly or silently) break existing code depending on these internal APIs without notice.
