`getrandom()` backwards compatibility shim
|
||
|
||
To restore compatibility with older Linux platforms where `getrandom()` is
|
||
unavailable either due to an outdated kernel or a legacy C library, Phobos now
|
||
ships with a shim that emulates a limited subset of `getrandom()`’s behavior
|
||
by reading random bytes from `/dev/urandom`.
|
||
|
||
To enable the shim, build DMD and Phobos with the environment variable
|
||
`LINUX_LEGACY_EMULATE_GETRANDOM` set to `1`.
|
||
|
||
```
|
||
cd phobos
|
||
LINUX_LEGACY_EMULATE_GETRANDOM=1 make
|
||
```
|
||
|
||
This functionality is a temporary fix and expected to be removed again soon
|
||
by an upcoming release (approx. v2.112.0 or v2.113.0).
|
||
The expected change is to replace the current “binding or shim” solution with
|
||
a syscall wrapper and automatic `/dev/urandom` fallback.
