Fixes: #64299

stream/iter now validates all writevSync() chunks before queueing a
batch. Previously, invalid chunks such as [1] could be queued first and
then throw from the queue’s byte-length accounting path, leaving invalid data
visible to the readable side.

This updates the shared chunk fast path to only skip conversion when every
entry is already a Uint8Array, and adds regression coverage that verifies
writevSync([1]) throws ERR_INVALID_ARG_TYPE without queueing data.

Ensure writevSync() validates every chunk before handing the batch to
the push queue. Invalid chunks now throw ERR_INVALID_ARG_TYPE without

stream: validate writevSync chunks before queuing

Ensure writevSync() validates every chunk before handing the batch to
the push queue. Invalid chunks now throw ERR_INVALID_ARG_TYPE without

Fixes: #64299
stream/iter now validates all writevSync() chunks before queueing a

batch. Previously, invalid chunks such as [1] could be queued first and

then throw from the queue’s byte-length accounting path, leaving invalid data

visible to the readable side.
This updates the shared chunk fast path to only skip conversion when every

entry is already a Uint8Array, and adds regression coverage that verifies
writevSync([1]) throws ERR_INVALID_ARG_TYPE without queueing data.

Fixes: #64299
stream/iter now validates all writevSync() chunks before queueing a

batch. Previously, invalid chunks such as [1] could be queued first and

then throw from the queue’s byte-length accounting path, leaving invalid data

visible to the readable side.
This updates the shared chunk fast path to only skip conversion when every

entry is already a Uint8Array, and adds regression coverage that verifies
writevSync([1]) throws ERR_INVALID_ARG_TYPE without queueing data.

Ensure writevSync() validates every chunk before handing the batch to
the push queue. Invalid chunks now throw ERR_INVALID_ARG_TYPE without
leaving data readable from the failed write.
