History

Dmitri Smirnov f14c3363e1 Make WinEnv::NowMicros return system time Previous change for the function `555ca3e7b7 (diff-bdc04e0404c2db4fd3ac5118a63eaa4a)` made use of the QueryPerformanceCounter to return microseconds values that do not repeat as std::chrono::system_clock returned values that made auto_roll_logger_test fail. The interface documentation does not state that we need to return system time describing the return value as a number of microsecs since some moment in time. However, because on Linux it is implemented using gettimeofday various pieces of code (such as GenericRateLimiter) took advantage of that and make use of NowMicros() as a system timestamp. Thus the previous change broke rate_limiter_test on Windows. In addition, the interface name NowMicros() suggests that it is actually a timestamp so people use it as such. This change makes use of the new system call on Windows that returns system time with required precision. This change preserves the fix for auto_roll_logger_test and fixes rate_limiter_test. Note that DBTest.RateLimitingTest still fails due to a separately reported issue.		9 years ago

README

This directory contains interfaces and implementations that isolate the
rest of the package from platform details.

Code in the rest of the package includes "port.h" from this directory.
"port.h" in turn includes a platform specific "port_<platform>.h" file
that provides the platform specific implementation.

See port_posix.h for an example of what must be provided in a platform
specific header file.
