* Forbid absl::Uniform<absl::int128>(gen)Gravatar Justin Bassett2024-05-24
| | | | | | std::is_signed can't be specialized, so this actually lets through non-unsigned types where the types are not language primitives (i.e. it lets absl::int128 through). However, std::numeric_limits can be specialized, and is indeed specialized, so we can use that instead. PiperOrigin-RevId: 636983590 Change-Id: Ic993518e9cac7c453b08deaf3784b6fba49f15d0

* `overload_test`: Remove a few unnecessary trailing return typesGravatar Dino Radakovic2024-05-23
| | | | | | | | | | `absl::StrCat` always returns a `std::string`. Specifying it using a trailing return type does not help. Tests are documentation, and they should be consistent with [the google style guide](https://google.github.io/styleguide/cppguide.html#trailing_return). For example, this is different than `-> absl::string_view` and returning string literals, where it is actually a load-bearing change.

* Support int128/uint128 in validated MockingBitGenGravatar Justin Bassett2024-05-21
| | | | | | | `absl::int128` and `absl::uint128` are not `std::is_integral`. There is an internal `IsIntegral` type trait we could use, but it actually makes more sense to remove the `static_assert` altogether. Any compile-time validation should be done in `absl::Uniform` itself, and duplicating that logic here just increases the chance of divergence.

* Add (unused) validation to absl::MockingBitGenGravatar Justin Bassett2024-05-20
| | | | | | | | | | | | | | | | | | | | | | | `absl::Uniform(tag, rng, a, b)` has some restrictions on the values it can produce in that it will always be in the range specified by `a` and `b`, but these restrictions can be violated by `absl::MockingBitGen`. This makes it easier than necessary to introduce a bug in tests using a mock RNG. We can fix this by making `MockingBitGen` emit a runtime error if the value produced is out of bounds. Immediately fixing all the internal buggy uses of `MockingBitGen` is currently infeasible, so the plan is this: 1. Add turned-off validation to `MockingBitGen` to avoid the costs of maintaining unsubmitted code. 2. Temporarily migrate the internal buggy use cases to keep the current behavior, to be fixed later. 3. Turn on validation for `MockingBitGen`. 4. Fix the internal buggy use cases over time. --- A few of the different categories of errors I found: - `Call(tag, rng, a, b) -> a or b`, for open/half-open intervals (i.e. incorrect boundary condition). This case happens quite a lot, e.g. by specifying `absl::Uniform<double>(rng, 0, 1)` to return `1.0`. - `Call(tag, rng, 0, 1) -> 42` (i.e. return an arbitrary value). These may be straightforward to fix by just returning an in-range value, or sometimes they are difficult to fix because other data structures depend on those values.

* Add a `string_view` overload to `absl::StrJoin`Gravatar Derek Mauro2024-05-13
| | | | | | | | | | | | | | | | | This allows users to pass a collection of string-like objects in an `initializer_list` without having to convert everything to the same type first. `initializer_list` has the requirement that everything is copied in to the list. For strings hitting the `string_view` overload avoids unnecessary copies. This may be a breaking change if `absl::StrJoin` has an explicit template parameter, for example `absl::StrJoin<std::string>({foo, "bar"});`. In this case, remove the explicit template parameter.
