* absl::string_view: Add support for starts_with() and ends_with()Gravatar Derek Mauro2023-10-20
| | | | | | | | | | | | | | | | when targeting at least C++20 These methods were added to C++20, so they are not available in earlier language standards. Users requiring compatibility prior to C++20 should use absl::StartsWith() and absl::EndsWith() from //absl/strings/match.h. Most users are not affected by this change. By default when targeting at least C++20 absl::string_view will be an alias for std::string_view. Only users that have modified //absl/base/options.h will see this change.

* Bazel: Support layering_check and parse_headersGravatar Derek Mauro2023-10-10
| | | | | | | | | | | | | The layering_check feature ensures that rules that include a header explicitly depend on a rule that exports that header. Compiler support is required, and currently only Clang 16+ supports diagnoses layering_check failures. The parse_headers feature ensures headers are self-contained by compiling them with -fsyntax-only on supported compilers.

* Check CRC cordrep child nodes for nullptr.Gravatar Martijn Vels2023-08-18
| | | | | | | Some time ago the invariant for CRC cordreps was relaxed to allow for nullptr values on empty cords with an explicit empty CRC value. The CordzInfo analysis never checked for nullptr values causing cord sampling to crash if the sampling happened to include a (very unlikely) empty Cord value.

The moving of `memmatch()` to `string_view.cc` decouples `string_view` from `memutil`, which will allow us to move `string_view` into its own target in a followup.
