CFLAG
FAKE_RANDOM
set, libfaketime will intercept calls to getrandom()
and return pseudorandom numbers for determinism. The mechanism needs to be activated by setting the environment variable FAKERANDOM_SEED
to a 64-bit seed value, e.g., "0x12345678DEADBEEF"
. Please note that this completely breaks the security of random numbers for cryptographic purposes and should only be used for deterministic tests. Never use this in production!FAKETIME_TIMESTAMP_FILE
is set, points to a writeable (creatable) custom config file and the environment variable FAKETIME_UPDATE_TIMESTAMP_FILE
is "1"
, then the file also is updated on each call. By this, a common "virtual time" can be shared by several processes, where each can adjust the time for all.LDFLAGS
can be passed via the environment variable FAKETIME_LINK_FLAGS
when running 'make
'.CFLAG
FAKE_SETTIME
can be enabled to intercept calls to clock_settime()
, settimeofday()
, and adjtime()
. (suggested and prototyped by @ojura)CFLAG
s can be passed via the environment variable FAKETIME_COMPILE_CFLAGS
when running 'make'.src/Makefile
CFLAG
FORCE_PTHREAD_NONVER
should be set on systems that hang on CLOCK_REALTIME
, or that hang on CLOCK_MONOTONIC
where FORCE_MONOTONIC_FIX
is not sufficient.Published by wolfcw about 5 years ago
