Download button shows progress remaining after download finishes


(Firefox :: Downloads Panel, defect)

20 Branch
Not set



Firefox 21
Tracking Status
firefox19 --- unaffected

(1 file, 2 obsolete files)

Setting = true breaks the download button in various ways:

* The finished notification animation isn't displayed
* The button continues to should some amount of time/progress left even through the download has finished.

I'm not sure when this started happening, but it should probably be fixed for Firefox 20 if it is going to be enabled by default.

1. Set = true
2. Download a file

Expected results:
When the download finishes, the button turns green and the notification animation is displayed.

Actual results:
When the download finishes, the button continues to display some time remaining and/or the progress bar. Clicking the button resets it to the default appearance.
I agree, a simple workaround would be to just not support that pref for 20, in case a proper fix is complicated.  Let's see.
I think the first issue is minor, though the wrong progressbar is not.
Confirmed on Ubuntu and OSX. Investigating...

Attached patch Patch v1 (obsolete) — Splinter Review
It looks like when is true, the download is removed *during* the state change from in-progress to complete, and so we get notified of its removal *before* we hear about it changing state to complete.

I believe this confuses our indicator code, since it gets a state change update when there are no downloads underway.

This patch makes the indicator data provider a little smarter in that it wipes out the counter and progress values when there are no more downloads in progress.

This doesn't, however, cause the indicator to get attention when the download completes - and this might be fine, since I don't know if we really want the download indicator to get attention on a completed download, since the button itself won't display anything useful after clicking it.

This seems to fix the bug.

The fact is that, for the indicator only, we enumerate the dataItems directly
from the DownloadsData object (without keeping our own copy of the list) during
the removal notification. But, we invoke the removal notification before we
actually removed the dataItem from the list.

Probably, moving the removal as the first line in _removeDataItem, before
onDataItemRemoved is called, will fix the issue.

I then suggest double-checking that the Library view isn't regressed by this
change, but I think not because it properly keeps its own copy of the dataItems,
it doesn't seem to use the global list.

Patch v1.1

Mike, if the approach in comment 6 works, please go for it instead of this
workaround - no need to ask for review again unless you just want more eyes
on the new patch. Otherwise, feel free to land the workaround.

This change does indeed fix the problem - thanks for clearing that up!

Library doesn't seem to be affected at all.
