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. Re-import of CCTZ from GitHub, applying new changes to honor Abseil's optional inline namespace in MSVC. 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.

-- c99f979ad34f155fbeeea69b88bdc7458d89a21c by Derek Mauro <dmauro@google.com>: Remove a floating point division by zero test. This isn't testing behavior related to the library, and MSVC warns about it in opt mode. PiperOrigin-RevId: 285220804 -- 68b015491f0dbf1ab547994673281abd1f34cd4b by Gennadiy Rozental <rogeeff@google.com>: This CL introduces following changes to the class FlagImpl: * We eliminate the CommandLineFlagLocks struct. 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.

2019-06-21 Use StrCat().Michael Shields1-1/+1
2019-06-20 Improve example AbslUnparseFlag().Michael Shields1-3/+3
1. Move default case outside switch. This is a good practice because it allows -Wswitch to warn about missing enum values. 2. Use absl::StrCat() instead of (nonexistent) SimpleItoa().
