Ease build of getrandom_test In trying to test the experimental getrandom features, I found a few minor problems. These changes should make it easier to test. After building, the developer can now just do: make -C test randomtest This will do a basic verfication that the feature works as expected. I haven't tried to integrate this with the overall "make test". To do that right, it should condition the test on the definition of FAKE_RANDOM. 2021-02-03 12:57:20 -05:00			`#!/bin/sh`

Make randomtest.sh use FAKETIME_TESTLIB like the rest of the test cases 2021-02-04 21:40:55 +01:00			`FTPL="${FAKETIME_TESTLIB:-../src/libfaketime.so.1}"`

Improve tests for FAKE_RANDOM Previously, we had failed to test code with getrandom() against LD_PRELOAD when FAKERANDOM_SEED was unset. We also want to try calling getrandom twice in a single process to make sure that works OK. 2021-02-22 22:37:33 -05:00			`set -e`

Test repeated invocations of getrandom() A single program that invokes getrandom() repeatedly should end up with the same stream of bytes, regardless of how it chunks up the reading from the entropy source. This test already passses. I'm including it because it seems like a useful confirmation. 2021-02-24 15:24:45 -05:00
