1169992 - [gui] Loading data for inbound builds is either too slow or hangs without an error message

Status: RESOLVED FIXED

(Testing :: mozregression, defect)

Description

[Marco Castelluccio [:marco]]

I'm using the mozregression GUI on Windows with inbound builds (2014/05/21 - 2014/05/22).
It hangs at "Looking for build data...", there's no indication whether it's still doing something or if some error occured and it can't continue.

Yeah, we have have issues with inbound builds download speed. Hopefuly bug 1132151 will help here. :)

Given the date range, you should see an error message "unable to find enough data to bisect" because there is no inbound builds so far in the past. This is what I got on running it (Linux 64).

There is a timeout of 30s for waiting connection, and 30s for waiting some available data (for each http request we are doing). You may have to wait more than that because we are actually doing a bunch of http requests - but you should see that "error" message at the end (say in 3 minutes max). If the program just hang too long, this sounds like a bug to me.

If I run this with a newer range (where we still have inbound builds) like 2015/05/21 - 2015/05/22, I can see the downloading step starting within a minute or two.

Marco, could you tell me how much time you waited ? And could you try again and wait around 3 minutes to see if that hang that long ?

Thanks for reporting this! 


Also one thing we could do is display a progress bar, to indicate that mozregression is doing something.

I've been waiting for 3 hours :D

I've also tried with a recent range, 2015-04-06 to 2015-04-07, but it doesn't work anyway.

(By "doesn't work" I mean it's stuck at "Loading for build data..." and there's no error message)

Erf, definitely it seems that something is wrong. I will try to reproduce that on windows. I'm pretty sure that moving to s3 will help here, but we have to wait a bit for that.

In the meantime, I'm thinking that we should print the mozgression logs we have somewhere (either in a file, or better directly in the gui). I'll think more about this and will raise an appropriate bug.

Hi Marco,

I just released mozregression-gui 0.3, and it uses taskcluster for inbound so I think it works better now.

I tried on windows, and everything seems pretty good to me.

Could you check and see if this bug is resolved for you ? Thanks!

It's working better now.
