Full example code to serve as a companion to An Intro to Zig's checkAllAllocationFailures

Clone this repository and run the following commands (requires latest master version of Zig):

• zig build test1: Run the initial test code. This should pass.
• zig build test2: Run the test code transformed to be compatible with checkAllAllocationFailures, but without actually using checkAllAllocationFailures yet. This should pass.
• zig build test3: Run the test code with checkAllAllocationFailures. This should fail due to a leak during fail index 1/5.
• zig build test4: Run the test code with checkAllAllocationFailures with the errdefer fixes in place. This should now pass.
• zig build test4 -Dcheck-allocation-failures=false: Run test4 but without checkAllAllocationFailures. This should pass.
• zig build caveat: Run a test case that will trigger error.NondeterministicMemoryUsage during checkAllAllocationFailures.
• zig build fuzz: Build an executable that will work with afl-fuzz. Requires AFL++ to be installed. See Fuzzing Zig Code Using AFL++ for more info.
  • After building, use afl-fuzz -i test/fuzz-inputs -o test/fuzz-outputs -- ./zig-out/bin/fuzz to start fuzz testing. No crashes should be found.
