Hi, and thanks for your report!

First, I'm sorry to say that I just don't believe you. I don't believe that kind of bug existed in that version of libcurl. I think you've seen this happen in your program's output, but the reason for that output is most likely to be found elsewhere.

But more importantly, you're using an outdated libcurl version and we're not really up to handle bug reports on that old versions. Please try the most recent libcurl version and if you can still repeat the problem then, please write a simple stand-alone example code for us to use to track down the problem.

The actual progress callback code has remained the same for a very long time.

** [bugs:#1229] Progress status not getting updated as expected**

I implemented the progress status callback in my application to display the percentage of file transfer progress via libcurl.  However, during my testing, there were many instances when the progress status did not get updated as expected.  For example, when I polled a file upload once every second, the upload percentage remained at 0.3% even though the uploaded file size was getting larger. Once the file upload was completed, I did get an update for 100% from the callback.  Note that this problem did not happen all the time, since I did get increased transfer percentage update in other cases.
