incorrect computation of cid on upload

[mastercyb]

cid of files uploaded through cyb.ai are differs from cid of the same files uploaded to go-ipfs

find related that correct ipfs hashes does not resolves

case https://cyb.ai/oracle/ask/QmeVMzMbknpwBU3pB7NhHjwvzVVeuUxAJ1wQnbkpQXPVAu vs https://emerald-raw-leopon-384.mypinata.cloud/ipfs/QmeVMzMbknpwBU3pB7NhHjwvzVVeuUxAJ1wQnbkpQXPVAu https://ipfs.io/ipfs/QmeVMzMbknpwBU3pB7NhHjwvzVVeuUxAJ1wQnbkpQXPVAu

looks like we will loose a chunk of content

0a means - new line, echo "хуй" > example.txt - adds new line to the end of file content O_o, cut new line manually now I got

ipfs add example.txt

added QmWQixYeubM54RFHunos6K6aYYb1EE4XY6pBVDJtTNGr9D example.txt

so no problem with cyb, everything fits. this workflow can be used for investigation of mentioned files.

Is this error related?

this prob not, related to ipfs resolving, fill be improved with next release

[dasein108]

@cyborgshead @mastercyb Problem is related to different block size of source node(chunker), so different block size/block count produce different hash. CID = hash of the root of merkle three CID != hash of the content (where blocks_count > 1)

[dasein108]

need to investigate of block size of helia & kubo(top ipfs implementation) and config chunker for same block size if that differs.
