Ed Schouten 323ade3e70 Make support for thread-unsafe C functions optional. ... One of the aspects of CloudABI is that it aims to help you write code that is thread-safe out of the box. This is very important if you want to write libraries that are easy to reuse. For CloudABI we decided to not provide the thread-unsafe functions. So far this is working out pretty well, as thread-unsafety issues are detected really early on. The following patch adds a knob to libc++, _LIBCPP_HAS_NO_THREAD_UNSAFE_C_FUNCTIONS, that can be set to disable thread-unsafe functions that can easily be avoided in practice. The following functions are not thread-safe: - <clocale>: locale handles should be preferred over setlocale(). - <cstdlib>: mbrlen(), mbrtowc() and wcrtomb() should be preferred over their non-restartable counterparts. - <ctime>: asctime(), ctime(), gmtime() and localtime() are not thread-safe. The first two are also deprecated by POSIX.

basic.string	While applying N4258, I forgot about LWG#2455, which modified the modifications. Correct those - h/t: Howard	2015-06-04 02:05:41 +00:00
basic.string.hash	libc++ implements its' hash objects as deriving from std::unary_function, and the tests test for that. STL @ MS pointed out that the standard doesn't requie these objects to derive from unary_function, and so the tests should not require that either. Change the tests to check for the embedded typedefs - which ARE required. No change to the library.	2015-01-07 21:53:23 +00:00
