Header refactoring: unify nstime.h and move it out of the catch-all 2017-04-18 07:17:02 +08:00			`#ifndef JEMALLOC_INTERNAL_NSTIME_H`

Refactor time_* into nstime_*. Use a single uint64_t in nstime_t to store nanoseconds rather than using struct timespec. This reduces fragility around conversions between long and uint64_t, especially missing casts that only cause problems on 32-bit platforms. 2016-02-22 03:25:02 +08:00

Stop depending on JEMALLOC_N() for function interception during testing. Instead, always define function pointers for interceptable functions, but mark them const unless testing, so that the compiler can optimize out the pointer dereferences. 2017-05-02 14:10:42 +08:00			`void nstime_init2(nstime_t *time, uint64_t sec, uint64_t nsec);`

Do not advance decay epoch when time goes backwards. Instead, move the epoch backward in time. Additionally, add nstime_monotonic() and use it in debug builds to assert that time only goes backward if nstime_update() is using a non-monotonic time source. 2016-10-11 13:15:10 +08:00			`typedef bool (nstime_monotonic_t)(void);`
