| * Cleanup `//absl/strings/internal/memutil.h`Gravatar Derek Mauro2023-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | | `memmatch()` is only used in `string_view.cc`, so move it there. 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. The only other function that is used is `memcasecmp()`, so delete all other functions. PiperOrigin-RevId: 547238386 Change-Id: Id6fad47dd24191c8e8f26dd923fffa1007c8db4a

| * symbolize_test: Add an indirection for getting the PC from function ptr.Gravatar Tom Rybka2023-07-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Don't assume that function ptr == PC. Adds a redirection mechanism, GetPCFromFnPtr, and enables more test cases for Emscripten/Wasm. On many (most?) platforms, the address of a function ptr is the same as its Program Counter (PC) for the purpose of most things, including symbolization. In Emscripten WebAssembly, the function ptr is just an index into a table of functions. However, the name section maps function names to their literal offsets into a Wasm binary. The WasmOffsetConverter is actually capable of both indirections, so we can effectively go from function ptr to offset into the binary (which is typically the "PC" for other Stack dumping things in Wasm, including `emscripten_pc_get_function`). More info: https://www.w3.org/TR/wasm-js-api-2/#exported-function-exotic-objects Also fix Emscripten symbolize handling for `nullptr` now that we have tests for that.

| * Correct std::optional/variant/any auto-detection for Apple platforms.Gravatar James Y Knight2023-07-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In Xcode 14.3, Apple modified the OS versions which support these three types to exclude iOS 11 and watchOS 4. Update abseil accordingly. Those versions of the OS did _not_ actually support the types, and any binaries which used these types, built with prior Xcode versions, would've crashed on startup on an actual iOS 11 or watchOS 4 device due to missing symbols. As of Xcode 14.3, using them is now, correctly, a build failure. This change also drops the conditionals for pre-Xcode 12.5, as that is no longer a supported version.

| * absl: fix Mutex writer starvation related to uninit priorityGravatar Abseil Team2023-06-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently when we queue the first thread, we don't init its priority. Subsequent queued threads init priority, but they compare it against the first thread priority, which is uninit. Thus the order can be wrong. It can lead to complete false starvation in some corner cases. On Linux the default priority is 0, which matches the uninit value, thus the problem is harder to spot on Linux (only possible if explicit thread priorities are used). But on Darwin the default priority is 31, thus the first thread falsely looks like lower priority than subsequently queued threads. The added test exposes the problem on Darwin. Always initialize the priority before queuing threads. PiperOrigin-RevId: 540814133 Change-Id: I513ce1493a67afe77d3e92fb49000b046b42a9f2
