Status for rust-byteorder-lite/0.1.0-1

Patch Description Author Forwarded Bugs Origin Last update
0001-port-to-quickcheck-1-rand-0.10.patch Port test suite to quickcheck 1.x / rand 0.10 (Debian ships neither 0.9 nor 0.7) Mechanical API renames only, verified to compile and preserve behaviour:
gen.gen::<T>() -> T::arbitrary(gen) (rand::Rng::gen replaced by recursing
into quickcheck's own Arbitrary, which is how quickcheck 1.x expects
primitives to be generated); Arbitrary::arbitrary<G: Gen>(gen: &mut G) ->
arbitrary(gen: &mut Gen) (Gen changed from a generic trait to a concrete
struct); StdGen::new(rng, size) -> Gen::new(size) (Gen now owns its RNG
internally, no external rand::Rng needed).
.
Known remaining gap, NOT fixed by this patch: prop_uint_N/prop_int_N/
prop_u24/prop_i24/prop_u48/prop_i48 (in mod test) fail under quickcheck
1.x. In quickcheck 0.9, Gen::size() bounded the magnitude of
arbitrary-generated primitive integers; qc_sized(prop, $max) relied on
this to keep generated values within the $bytes-wide range these tests
write/read. In quickcheck 1.x, primitive Arbitrary impls generate
full-range values unconditionally (size no longer bounds magnitude, only
collection lengths), so out-of-range values are generated and the
truncating round-trip through $write/$read legitimately fails -- through
no fault of the library code itself, which has zero runtime dependencies
and is unaffected.
.
A correct fix requires re-deriving bounded-integer generation for each
integer width exercised by the qc_byte_order! macro (used at ~130 call
sites, some via the plain integer types u16/i16/u32/i32/u64/i64, others
via the crate's own Wi128<u128>/Wi128<i128> wrapper, which already
self-bounds via Gen::size() using a DIFFERENT convention -- for those
calls Gen::size() is deliberately set to the target byte count itself,
e.g. qc_byte_order!(prop_uint128_1, Wi128<u128>, 1, 1, ...) -- so a single
uniform wrapper cannot be dropped in without either double-bounding the
Wi128 cases or leaving the plain-integer cases unbounded. This is a
test-suite redesign, not a packaging-scoped patch; marked test_is_broken
in debian/rules instead (see debcargo.toml) pending an upstream fix.
