Description

Because I need to investigate the solution of the copy/paste of an image, I modified some code related to the clipboard.

When I click the guacamole client page after copy the image, the ManagedClient.setClipboard() function is called to send the blob of the image to the guacamole server.

When the size of data to be sent is more than 6048 bytes, the readNextChunk() function is called only once in BlobWriter.sendBlob().

Because arrayBufferWriter.onack() isn't called.

So, only the 6048 bytes are sent in the whole data.

 

I think that to directly call readNextChunk() after call of arrayBufferWriter.sendData() in chunkLoadComplete() of BlockWriter.js may be a solution.

 

Please help.

Thanks.
