Fixture for Trustless Gateway Car Testing

file-3k-and-3-blocks-missing-block.car

We generate a random file, chunked into 3 * 1024 blocks. Then use go-car to remove the middle block. At the end, we nuke the repo to make sure there are no providers for the removed block.

This is necessary for testing edge case described in gateway-conformance#75.

dd if=/dev/urandom of="file-3k-and-3-blocks.bin" bs=1024 count=3
CID=$(ipfs add ./file-3k-and-3-blocks.bin --chunker=size-1024 -q)
ipfs dag export $CID > file-3k-and-3-blocks.car
REMOVE_BLOCK=$(ipfs dag get $CID | jq '.Links[1].Hash["/"]' -r)
echo $REMOVE_BLOCK | car filter --version 1 --inverse ./file-3k-and-3-blocks.car ./file-3k-and-3-blocks-missing-block.car
ipfs pin rm $CID; ipfs repo gc
# First and third outputted CIDs are used in the missing blocks tests.
ipfs dag get $CID  | jq .Links | jq -r '.[].Hash."/"'
