Summary:
The fuzz tests need `TestContext::id_dag()`, which was removed by D20471712 (1fb5acf242).
Restore it so fuzz tests can run. This is mainly to check the new `range`
function.
The `range` fuzz test does find an issue caused by `>` written as `>=`
relatively quickly.

Steps to run the fuzz tests with OSS toolchain:
|
|
|
|
1. Install rustup.
|
|
2. `rustup install nightly` to install nightly toolchain.
|
|
3. From `eden/scm`, run `rustup override set nightly && make local` to use the nightly toolchain.
|
|
4. From `dag` (parent directory of `fuzz`), run `cargo fuzz run $TEST_NAME`. For example, `$TEST_NAME` can be `range_medium`.
|
|
|
|
`cargo fuzz` supports some options. For example:
|
|
|
|
cargo fuzz run --release -j 16 gca -- -max_len=20
|
|
|
|
will build in release mode, fork into 16 processes, and generate at most 20-byte input.
