* Migrate most RAW_LOGs and RAW_CHECKs in tests to regular LOG and CHECK.Gravatar Andy Getzendanner2023-05-23
| | | | | | | | | | | The non-RAW_ versions provide better output but weren't available when most of these tests were written. There are just a couple spots where RAW_ is actually needed, e.g. signal handlers and malloc hooks. Also fix a couple warnings in layout_test.cc newly surfaced because the optimizer understands CHECK_XX differently than INTERNAL_CHECK.

| | | | | | | | | On Linux Kernels >= 5.4 MSan reports a false positive when accessing thread local storage data from loaded libraries.

Static initializers are problematic for a number of reasons. Not only are they responsible for the static initialization order fiasco, but they are in the critical path during program startup. For these reasons, the Google C++ style guide strongly discourages them (and forbids them when they are not trivially destructible), and Chromium even has a test forbidding them. https://google.github.io/styleguide/cppguide.html#Static_and_Global_Variables https://chromium.googlesource.com/chromium/src.git/+/master/docs/static_initializers.md http://neugierig.org/software/chromium/notes/2011/08/static-initializers.html PiperOrigin-RevId: 289458677 -- c869362f6bb7a872314f74750d38d81bdaa73f95 by Greg Falcon <gfalcon@google.com>: Step 2 of 2 to fix our CCTZ fork to respect inline namespaces.

PiperOrigin-RevId: 289454407 -- fdb3474d76c2ee0371ccdf7593a78137c03a3f58 by Greg Falcon <gfalcon@google.com>: Step 1 of 2 to fix our CCTZ fork to respect inline namespaces. CCTZ uses a linker flag to simulate weak symbol support in MSVC. This takes the form of a #pragma that includes the mangled names of two types: the symbol to treat as weak, and the symbol to use as its default value if no override is provided. When Abseil is configured to use inline namespaces, the mangled names of these symbols change, and the pragma should change to reflect that. Fortunately for us, MSVC name mangling is simple enough that we can generate the needed string literals in the preprocessor. This CL introduces the new macros; the uses will be introduced in a follow-up CL.

Instead callback guard and callback function are combined into a single CallbackData struct, while primary data lock is stored separately. * CallbackData member of class FlagImpl is initially set to be nullptr and is only allocated and initialized when a flag's callback is being set. For most flags we do not pay for the extra space and extra absl::Mutex now. * Primary data guard is stored in data_guard_ data member. This is a properly aligned character buffer of necessary size. During initialization of the flag we construct absl::Mutex in this space using placement new call. * We now avoid extra value copy after successful attempt to parse value out of string. Instead we swap flag's current value with tentative value we just produced.
