T Jake Luciani commented on CASSANDRA-9276:
-------------------------------------------
You're right. this should be assert cis.getTotalCompressedBytesRead() <
totalSize
> StreamingTransferTest fails under test-compression due to bad assertion

> {noformat}
> assert in.getBytesRead() < totalSize;
> {noformat}
> My guess is that total size is the compressed size, not the uncompressed
> size. Remove the assertion and the test passes.
> Total size is calculated with
> {noformat}
> long size = 0;
> // calculate total length of transferring chunks
> for (CompressionMetadata.Chunk chunk : compressionInfo.chunks)
> size += chunk.length + 4; // 4 bytes for CRC
> return size;
> {noformat}
