Tranfer gets interruped for some files no matter retries

[EmmanuelMess]

PC: Ubuntu 18.04 with Unity 7 linux 4.15
Phone: LG K11α

Transferring a few images, some always fail:

And they seem to be always the same photos:

• IMG_20190527_085610
• IMG_20190527_085612
• IMG_20190527_085614
• IMG_20190527_085615

I received these (partial) files (compressed to be able to upload to GitHub).

Hi @EmmanuelMess, I haven't been able to solve this problem yet. It is happening on my machine as well.

Count me in too, i don't know why but if i double-click to restart sending the interrupted file when another file before is running the sending file, sometimes it completes, who knows why, but almost all the times if fails...

@velitasali Any ideas on what is the problem?

@EmmanuelMess There is an ongoing issue with IO during transfer.

On this line, bytesToReceive() always returns a positive number though there is not, creating an issue on the other side of the connection. To prevent that I added checks after that if statement, still, we have issues.

I am still not sure how to fix that.

@velitasali
Ok, I don't have much experience with Qt.
And I haven't run the code.
But, if I may give some advice.
Are you compressing, or better, tarring, before sending? So that we can rule out metadata problems.
