https://issues.dlang.org/show_bug.cgi?id=20813 Issue ID: 20813 Summary: std.experimental.allocator add fault injecting allocator Product: D Version: D2 Hardware: x86_64 OS: Linux Status: NEW Severity: enhancement Priority: P1 Component: phobos Assignee: nobody@puremagic.com Reporter: witold.baryluk+d@gmail.com A feature request of adding an allocator building block that with a given probability simply fails to allocate memory and returns null. Otherwise allocate from the parent. Determination can be done using per-thread random generator for example. Extra conditions (i.e. do different probabilities for different sizes) can be done using other allocator building blocks. As a bonus it might be useful in some cases to fail multiple consecutive calls to allocate(), not just do it every 1000 calls. I.e. fail 3 calls to allocate(). -- |
