The mozregression GUI does not start on macOS Big Sur Developer Beta 1. You can see the app icon in the dock but nothing happens, the activity manager shows almost 100 percent CPU for the mozregression GUI and you have to force close the app.

Tested with the current version 4.0.7.

The severity field is not set for this bug.
:wlach, could you have a look please?

For more information, please visit auto_nag documentation.

urllib3 just got bumped to 1.25.10 which contains the following in its changelog:

Fixed loading of SecureTransport libraries on macOS Big Sur due to the new dynamic linker cache (Pull #1905)

So it'll be interesting to see if that makes any difference (though there could well be other dependencies with similar issues we'll have to wait for).

So it'll be interesting to see if that makes any difference (though there could well be other dependencies with similar issues we'll have to wait for).

Unfortunately today's build which should contain the urllib3 bump still don't start.

[Tracking Requested - why for this release]: Mozregression is important for our ability to debug problems.

I agree we that should fix this, but it's not really a Firefox bug either.

Is this a priority ahead of the BigSur update? If so, Who owns this work?

The mozregression CLI can still be used so I don't think this is high priority.

I did request tracking in comment 5, but now I realize at that time I was confused and was attributing an unrelated failure to this bug.

ah, ok, thanks!

Haik, do you mean to say that the command line version of the mozregression works on Mac OS 11?
Are you sure? Are you using it? Can you help me understand how to make it work?

I'm able to use mozregression with a command such as

$ mozregression --good 2020-12-01 --bad 2021-02-01

One thing to watch out for is that macOS 11 required some fixes in order to run and therefore old versions may not work which is a hindrance to mozregression. In particular, the fix for bug 1648836 was needed for basic functionality.

What is the problem you are running into?

While attempting to install mozregression CLI, I needed to:

1. Remove the python 2.7
   I have attempted removing it using methods seen here:

• https://stackoverflow.com/questions/3819449/how-to-uninstall-python-2-7-on-a-mac-os-x-10-6-4
• https://www.macupdate.com/app/mac/5880/python/uninstall
  but I believe that wasn't completely removed and I don't know how to do it.

2. install Xcode tools with the command:
   xcode-select --install
3. install python3 with the commands:
   brew install python3
   and
   brew reinstall python@3.9
4. install mozregression with the command:
   pip3 install mozregression

The install process begins and appears to be working until some errors get displayed:

@haik: Can you tell me how I can properly install it?

Given that's mentioning cargo it looks like you might need Rust installed to compile the glean-sdk package: https://rustup.rs/

(In reply to Ian Moody [:Kwan] (UTC+1) from comment #15)

Given that's mentioning cargo it looks like you might need Rust installed to compile the glean-sdk package: https://rustup.rs/

We should have wheels for the glean-sdk (which would eliminate the need to recompile), but it appears that there's not one for the latest version:

https://pypi.org/project/glean-sdk/34.0.0/#files

Mike, could you or someone on your team investigate this?

Grump, just realized this bug is tracking another (real) issue. I'm going to file a new one.

Oh, the latest release failed to produce macOS wheels and I forgot to do a followup patch release.

Finally upgraded to Big Sur yesterday and reproduced this issue. Looks like we need to upgrade the version of python used by the GUI to 3.9.1:

https://github.com/pyinstaller/pyinstaller/issues/5107

Probably best done with bug 1686039

The new version mozregression 4.0.17 finally works on macOS Big Sur. :)
