* absl: reformat Mutex-related filesGravatar Abseil Team2023-06-20
| | | | | | | | | | | Reformat Mutex-related files so that incremental formatting changes don't distract during review of logical changes. These files are subtle and any unnecessary diffs make reviews harder. No changes besides running clang-format. PiperOrigin-RevId: 541981737 Change-Id: I41cccb7a97158c78d17adaff6fe553c2c9c2b9ed

* Rename AsyncSignalSafeWriteToStderr to AsyncSignalSafeWriteError.Gravatar Abseil Team2023-06-15

* DirectMmap: Use off_t instead of off64_t for the offset parameterGravatar Derek Mauro2023-06-12
| | | | | | | | | | | | | | | | off_t is best for portability. Its size varies with the platform. off64_t is non-standard, but is present in glibc and some BSDs. It also matches the signature specified in the manual. https://man7.org/linux/man-pages/man2/mmap.2.html This is a re-spin of #1349, but correctly casts the type to the type expected by the kernel for mmap2. https://man7.org/linux/man-pages/man2/mmap2.2.html Fixes #1473 PiperOrigin-RevId: 539656313 Change-Id: I7a30dd9d3eb6af03a99da0d93d721a86f6521b25

* Name anonymous memory allocations on Linux.Gravatar Abseil Team2023-04-12
| | | | | | | | | | | | | | | | | | | Use Linux's prctl(PR_SET_VMA) system call to name memory arenas being allocated using mmap(MAP_ANONYMOUS). This change allows Abseil's memory arena(s) to be distinguished from other uses of anonymous memory within a process, which in turn helps investigations into the memory usage of applications. The change adds a new prctl() system call to the code paths that call mmap(). This is not expected to add significant overhead to applications. The call to prctl(PR_SET_VMA, ...) can fail if the Linux kernel in use was not configured with the CONFIG_ANON_VMA_NAME kernel option. This should be OK since the naming memory regions is primarily a debugging aid. PiperOrigin-RevId: 523687348 Change-Id: Ie404e5eeef0a6da53330b3a56149c4f3bc6bf5c7
* Add an implementation of Waiter that uses std::mutex/std::condition_variableGravatar Derek Mauro2023-03-21
| | | | | | | | | | | | | | | This implementation may at some point become the default on some platforms. Currently not all platforms have widespread support for both real absolute timeouts or real relative timeouts (here "real" means without converting to the other timeout type which is the only one supported by the underlying APIs). In this case we can defer to their standard library to implement correct support. This is not currently the default on any platform Note: The size of WaiterState had to increase to fit the new implementation PiperOrigin-RevId: 518266646 Change-Id: I7f246646a960d6e1b155f9de0bf2f681c5d3d245

* Delete the `Throw()` function from `absl::base_internal`.Gravatar Devin Jeanpierre2023-03-01
| | | | | | | This was originally added in order to centralize the ifdefs, in cl/164484905. However, cl/337142938 undid this aspect of the change, because it broke on Android. What is left is vestigial: `Throw()` can be deleted at no loss, with a warning that should discourage us from ever reintroducing it.
