In bug 1309125, bug 1309668, and bug 1309660 we changed update mar download throttling to 0 which disables throttling and added support for remotely changing the throttling in case we found that we needed it as a "just in case". This was fixed in Firefox 50 so we've had a couple of releases where the download was not throttled.
oremj has ok'd completely removing the throttling over email and the networking team has asked to move away from nsIIncrementalDownload.
This is not critical but we should change app update to use the standard networking download code instead of nsIIncrementalDownload.

Matt, I split out your changes to remove nsIIncrementalDownload from bug 1343671 and put it in this bug so this can download while bug 1343671 is in progress and to make the patches simpler in bug 1343671.

I suspect that this will get flagged as a perf problem. See bug 1361102. Either you or I can ask around how to best accomplish this while limiting jank. I would hope the download manager already has this figured out.

I looked into what the download manager does, and it's handling file output on a separate thread by forwarding it through a purpose-built necko thing called a BackgroundFileSaver. I'll try adapting that method here.

Above try push shows one of the chrome tests timing out on Linux and Mac. I'll investigate.
It also shows this failure:

which does not look related to this bug, but should get looked into anyway.
And there's an internal error in eslint there too, just for fun. Not sure what to do about that.

I think you can just do what DownloadCore.jsm does as follows
const BackgroundFileSaverStreamListener = Components.Constructor(
"@mozilla.org/network/background-file-saver;1?mode=streamlistener",
"nsIBackgroundFileSaver");
...
this._bkgFileSaver = new BackgroundFileSaverStreamListener();

I triggered 5 more runs and I suspect that is a pre-existing intermittent. I'll trigger a few more.

One of the things that is hard to catch are tests that start failing when they run parallel with other tests but typically pass during when they are automatically ran again by themselves. I have a bash script that does this and pipes the results to a file so I can check if a change has increased the parallel failure rate. It looks like these changes significantly increased the unit_aus_update parallel failures and I also had some failures when they ran again by themselves.
The tests that failed the most often were
downloadInterruptedRecoveryChannel.js failed 15 times parallel out 50 runs and also failed non parallel 2 out of 50 runs
downloadInterruptedOffline.js failed 7 times parallel out 50 runs
These can be extremely hard to diagnose since they don't have log output when they run in parallel. To deal with this I usually change the LOG function in nsUpdateService.js to also output to a file or override dump in xpcshellUtilsAUS.js so it outputs to a file as well as outputs to the original dump.

Main changes:
- Applied the workaround from comment 16 to fix the eslint internal error
- Wait for the BackgroundFileSaver to notify us that it's done writing instead of just assuming the file will be ready immediately after calling finish
- Updated the cancel method, since I forgot to do that when I added the BackgroundFileSaver
Robert, if this version doesn't do any better with your parallel runs, can you send me that bash script you're using?

The bash script is dirt simple and nothing special. It just makes it easy to run a bunch of tests without me having to babysit it.
#!/bin/sh
rm ../../_out
END=50
if [ $# -eq 1 ]; then
END=$1

for ((i=1;i<=END;i++)); do

Test runs are looking good! The only one possibly related was one parallel failure out of 50 runs for downloadResumeForSameAppVersion.js which passed when it ran by itself.

Cancel didn't remove the file previously.
This makes it so if a client exits while a download is happening the download starts over.
I also noticed that the download progress updates is way too fast especially when compared to how it is without this patch.

It is. I was seeing this failure locally until I made the changes to cancel(), so I thought it was gone. Having resume support will change how that works, so this might look different after that.

Not certain what you mean here. This is in the about box? And it updates too rapidly to be able to read?

I'll give it a shot. Looking at the download manager makes me think it's definitely possible and it _shouldn't_ be too hard...

In the about dialog the download progress updates extremely fast. You can try it out on oak to see it.

Okay, I understand. The incremental downloader gets around this by making the OnProgress calls itself instead of passing the channel's through, and throttling those down on a half-second interval. I'll see about replicating that.

Throttled OnStatus to only call listeners every half second, and implemented resuming downloads; I've checked in the test logs to make sure that code is functioning, since otherwise it's kind of silent.
Since I'm tired of the Linux chrome tests giving me trouble, I left them running in a loop overnight (that's 1,920 runs) and with this patch I have no failures; before I could get about 1 failure in 10 runs.
Will also push to try in a bit.

So, the new code expects the maxProgress to be from where it left off and hence resuming the download fails.
Also, statusText is now just the hostname which doesn't seem right.
Please also add a test that copies a portion of the complete mar to the test's update.mar and then resumes downloading the mar file. It can be based off of downloadResumeForSameAppVersion.js.

Intervals are no longer used after nsIIncrementalDownload is removed so the following should also be done:
Remove the constants for DOWNLOAD_BACKGROUND_INTERVAL, DOWNLOAD_FOREGROUND_INTERVAL, and PREF_APP_UPDATE_BACKGROUNDINTERVAL.
Remove the nsIUpdate backgroundInterval property.
Remove the app.update.download.backgroundInterval preference from the Firefox preference file.
Please file a releng bug to remove backgroundInterval support from balrog as well.

I'm tempted to say that this should be added to nsIUpdatePatch instead of it being a one-off property though I am very much on the fence. If this is what you are expecting to throw you could go with if default value then remove the file, etc.

It isn't expected if the file already exists though. Would be good to document how that state could happen.
Since the patch file has to exist to get this far what do you think about removing the patch file since it has to start downloading from the beginning?
This case should also be recorded in telemetry.

Even though the cost of calling formatStatusMessage is likely small I don't think it is worthwhile for this. I think it is better to just remove it.

This will make it so on resume the listeners get progress and maxProgress that don't take into account what was previously downloaded. So, if there is a progress bar it could be close to 0 even when more than half of the update has been downloaded.

The mar file is an even number at this time but that could change. Would it make sense to just go with SIZE_SIMPLE_MAR - 200?

I'd rather not add it to the interface, just because I think it's an implementation detail of the downloader and nothing else should need to know about it.

You're right, I don't think this could happen unless something other than the update service created the file or something really odd and broken happens with the file system; I think I'll just take out the comment.
> Since the patch file has to exist to get this far what do you think about

> This case should also be recorded in telemetry.
I think deleting the patch file here isn't necessary because the BackgroundFileSaver always overwrites the target from the beginning if you don't call enableAppend.
I'm not sure how to handle this for telemetry. The obvious thing is to add a new download status code, but I'm not sure how that would work because this is at a sort of intermediate stage that we didn't have before, and it isn't fatal to the download. Do you think that would make sense, or should I add a new histogram (or scalar maybe)?

Yeah, I put it in because I get failures in some chrome tests otherwise. There might be somewhere earlier that it makes sense to put this, I didn't really investigate that; I kind of like having it right where the interface is used anyway.

iirc most of the download codes aren't fatal and I think it should be fine to report it as just a new code. I think that several of them are intermediate as well.

It wasn't doing the right thing. For some reason I thought getProperty would throw when the property wasn't found, but it actually returns null. That means that the entityID was implicitly optional, but I had intended for resuming to be skipped without it, as a way of being certain that we really were resuming the same patch. This was also hiding the fact that the entityID wasn't ever getting read out of the XML in the first place. :(
I think I'll also add another test to check that the download proceeds normally without trying to resume when an entityID isn't present.

You've added a couple of extra spaces here. When entityID doesn't exist there is the extra space after state and the one added above with " />".
Instead, just add entityID before state and revert state above to how it was previously.

I'm lukewarm about using an object for options here. If you go with an object please fix the comment above so it reflects reality since options.errorDownload is also a valid param.

Slightly concerned about not using the helpers that verify the xml files to be in a consistent state. If any of the tests without it start to intermittently fail it can be fixed in the intermittent bug.

Yeah, I had forgotten. I asked in #fx-team and didn't get a response, so I checked the commit log for xpc.msg and from that it doesn't look like anyone else's review is needed.

It doesn't, because entityID goes in the property bag and not directly in the object. I think this is the only place it really needs special attention for that reason, so I left it alone.

I didn't want to start introducing new boolean positional arguments. I could switch to using a destructured object there instead to make it slightly more ergonomic, but it looks like a wash to me.
I'll certainly fix the doc comment though.

Part 1 - Client code
When I made it so an nsIUpdate could have and write arbitrary values I never made it so nsIUpdatePatch could have and write arbitrary values.
I *think* I'd prefer that it can but I don't think that has to happen in this bug.
Also, the this._update.QueryInterface(Ci.nsIPropertyBag) makes more sense to me now and I'll probably clean that up later.

I was trying to connect the two. It isn't blocking because it is resolved. Perhaps I should use see-also or else create a meta bug that tracks what broke in updates for 58.0b1 users. Does that make sense?
