* Replace absl::type_traits_internal::is_trivially_copyable withGravatar Derek Mauro2023-04-12

* 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

* inlined_vector: relax the requirements on the move-construction fast path.Gravatar Aaron Jacobs2023-04-11
| | | | | | | | | Don't require a trivial move constructor and trivial destructor. This excludes types that have declared themselves trivially relocatable by another means, like std::unique_ptr. Instead use "is trivially relocatable" directly, which includes all previous types as well as those that have opted in.

* inlined_vector: optimize the move-assignment fast path.Gravatar Aaron Jacobs2023-03-31

* type_traits: provide a better fallback for is_trivially_relocatable.Gravatar Abseil Team2023-03-24
| | | | | | | | | | We can do a lot better than always saying "no" on platforms without the __is_trivially_relocatable builtin. This will allow using this type trait from the move constructors of InlinedVector in a future CL, without needing to open code the fallback logic.

* inlined_vector: get rid of IsMemcpyOk.Gravatar Abseil Team2023-03-24
| | | | | | | | | | | | | | This type trait had no precise definition, and indeed not even any documentation at all. Giving the ill-defined concept a name was harmful, because it obscured several places where the concept was used too conservatively, or even flat-out incorrectly. This CL has no behavior change: it simply expands IsMemcpyOk to the same conditions it previously had. It leaves TODOs for each place where this was too conservative or incorrect.

* type_traits: touch up the docs for is_trivially_relocatable.Gravatar Abseil Team2023-03-24
| | | | | | | | | | | Clarify that the trait is conservative: it's safe to act on if it's true, but false doesn't necessarily mean anything. Of course this is the only reasonable way to use it, but I think it's helpful to be explicit, especially because currently this trait *always* returns false on some platforms even for a type like int.
