* Workaround symbol resolution bug in Clang 19Derek Mauro2024-05-242-1/+12
| | | | | | | | | | | | | | Clang 19 seems to see the old usage of absl::string_internal::HasAbslStringify in GoogleTest 1.14.0 and incorrectly resolves absl::HasAbslStringify sometimes. This issue is fixed when a version of GoogleTest that removes absl::string_internal::HasAbslStringify is used. This workaround is ugly but will be removed after the next GoogleTest release.

* Add a `string_view` overload to `absl::StrJoin`Derek Mauro2024-05-132-4/+53
| | | | | | | | | | | | | | | | | 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.

* `convert_test`: Delete obsolete condition around ASSERT_EQ in ↵Dino Radakovic2024-05-101-9/+7
| | | | | | | | | TestWithMultipleFormatsHelper The `if (actual != expected)` makes the `ASSERT_EQ(actual, expected)` trigger only when the assertion fails. However, a successful `ASSERT_EQ` takes a negligible amount of time, which means the `if` is useless and only makes the test harder to read.

* `convert_test`: Extract loop over tested floats from helper functionDino Radakovic2024-05-061-14/+18
| | | | | | | | | | 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

* Work around an implicit conversion signedness compiler warningAbseil Team2024-03-071-1/+5
| | | | | | | | | | | Addition and subtraction operators std::array::iterator are defined only for ptrdiff_t, which is signed, instead of size_t, which is unsigned. Therefore, adding the index variable to ar.begin() will trigger -Wsign-conversion if std::array::iterator is not a raw pointer because the index variable will be implicitly converted from size_t (an unsigned type) to ptrdiff_t (a signed type). To fix this, we explicitly static_cast index to a ptrdiff_t. PiperOrigin-RevId: 613662928 Change-Id: I5e06c2261d7b8f167fae7bb6acece076257f8579

* Prevent overflow in `absl::CEscape()`Derek Mauro2024-02-141-4/+22
| | | | | | | | | | | | | | | | | | Strings larger than 1 GiB on a platform with a 32-bit size_t could potentially overflow size_t in `CEscapedLength()`, resulting in an undersized allocation. The resulting write in `CEscapeAndAppendInternal()` would then write beyond the bounds of the output buffer. A second overflow, where the calculated escaped length is added to the size of the string being appended to, is also fixed. In both cases the program will now abort prior to the overflow. Credit goes to Ronald Crane (Zippenhop LLC) for reporting this issue. PiperOrigin-RevId: 607019573 Change-Id: I97bf246cde96102a793d2db49446cccae08abf59
