825914 - OSX will sleep in the middle of a Firefox download

Status: NEW

(Core :: Widget: Cocoa, defect, P3)

Description

[benj.browder]

Attachment: Screenshot showing no assertion set when downloading

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:17.0) Gecko/20100101 Firefox/17.0
Build ID: 20121128204232

Steps to reproduce:

Downloaded a test file on a clean installation of Mountain Lion. File in question was the Android SDK bundle.


Actual results:

File began to download as it should. However, the browser fails to set an assertion preventing disk sleep while in the middle of the download. This will interrupt any download because the download will be interrupted by the computer's sleep cycle. Not setting an assertion can be checked by:

pmset -g assertions


Expected results:

The browser should have set an assertion preventing idle disk sleep until the download is completed.

OS X sends the hdd in the sleep mode while data is written to the disk ?
That sounds really stupid.

moving to Widget:Cocoa as first try but Core:File handling could be the better one.

Tested on El Capitan OSX 10.11.6

System Preferences > Energy Saver > Power Adapter:
- Turn Display off after: 1 minute
- (not selected) Prevent computer from sleeping automatically when display is off
- (selected) Put hard disk to sleep when possible
- (selected) Wake for network access
- (selected) Enable Power Nap while plugged into power adapter
-- power adapter plugged in  
Note: the above settings, other than display time,  are the defaults.

1) began download of large file, in this case an ubuntu iso. ~17 minutes estimated download time
2) left computer alone and after a minute screens(s) went to sleep.
3) after 10 minutes, wake computer from sleep
4) check download status

tested results:
the download was paused, but after a moment it continued to download from where it left off, status showed ~15 minutes remaining.

The computer should finish the download, then sleep.

Moving to p3 because no activity for at least 1 year(s).

This is still relevant with Firefox 68.0.1 on Mac OS 10.14.6.

Can you please fix this now? It is very annoying. Any technical reasons holding you back here?

This is how Chromium does it:
