ETA causes crash in

[tivaro]

The following code works with progressbar2==3.6.2,
however, when progressbar2==3.8.0 it breaks.

The download stops working after the first iteration. (the script just hangs)

I played with the code for hours, I thought it might have something to do with the uneven update sizes, but it doesn't. Interestingly AbsoluteETA does not cause a crash, but displays elapsed time instead of ETA.

I am using python 2.7.6 on Ubuntu 14.04

def default_pbar(max_value=None, prefix='     '):
    widgets = [
        prefix,
        progressbar.Bar('=', '[', ']'),
        #' ', Bar(marker=progressbar.RotatingMarker()),
        ' ', progressbar.Counter(), '/', `max_value`,
        ' ', '(', progressbar.Percentage(), ')',
        ' ', progressbar.FileTransferSpeed(),
        ' ', progressbar.ETA(),
        ' ',
    ]
    return progressbar.ProgressBar(widgets=widgets, max_value=max_value, redirect_stdout=True)

def retrieveFile(web_location, local_location):
    #progressbar update function
    def dlProgress(count, blockSize, totalSize):
        if pbar.max_value != totalSize:
            pbar.max_value = totalSize
        pbar.update(min(count*blockSize, totalSize))

    dl_size = int(urllib.urlopen(web_location).info().getheaders("Content-Length")[0])
    pbar =default_pbar(dl_size)
    pbar.start()
    urllib.urlretrieve(web_location, local_location, reporthook=dlProgress)
    pbar.finish()

retrieveFile('ftp://ftp.ncbi.nlm.nih.gov/pub/pmc/articles.A-B.tar.gz', 'articles.A-B.tar.gz')

That's really unfortunate, I'll see if I can find the cause of the problem

I found the problem, it simply wasn't updating often enough. It works as expected again. I'll create a new release within a few hours :)
