I'm declaring this done. Email+password works, as does OAuth for Github,Google and Apple. I couldn't get the Microsoft OAuth process to work at this time, I can see we'll need to revisit this as we go to production, and add in enterprise SSO methods.

Epic: Create tab to edit variables together

This is already implemented as the summary tab. The question is whether to add description fields and slider values - the problem being there is limited real-estate in the table.

I'll help you investigate why bumping Electron above version 37 breaks the canvas functionality on Windows. Let me start by gathering information about this repository and the specific changes in PR #636.I'll now search for issues related to Electron version upgrades and canvas rendering problems on Windows.Based on my investigation of the Minsky codebase and the PR that bumps Electron from 37.10.3 to 41.1.1, I can help you understand the likely cause of the canvas rendering issue on Windows. Investigation...

Finally, this is the last update to the build environment for Intel Macs. When it fails, or Apple updates the build requirements again, we're going to have to drop Intel support. Hopefully that won't be for another 2-3 years.

Upgrade Intel Mac build environment to Monterey
-
Just finished :P. Took almost 3 weeks. In the end, I had to abandon the Virtual Machine approach. Virtual Machines were just too much of a nightmare with a Monterey guest system, so I will be building on the base system, and testing on the M2 system using Rosetta. Had extensive problems sorting out the code signing certificate, but Claude Sonnet eventually found the obscure configuration that needed to be flicked.
-
You're welcome! That approach strikes a great balance between robust security and cross-platform simplicity. Since you have control over the build pipeline, the detached signature method effectively treats your .dll, .dylib, and .so files as immutable data blobs, which is exactly what you want for stable verification. To wrap things up, here is a quick "cheat sheet" for your implementation: Build Pipeline (The Signer) Use OpenSSL to generate the signature during your CI/CD process: Bash Generate...

We're in the process of upgrading Angular 20->21. This error is suspiciously similar to the blank window error, which is due to incompatibilities with import functions.

Thanks. Sorry I couldn't make it last night - I had a long-standing commitment elsewhere.

PlotWidget moveTo/position resolves to empty EventInterface stub via REST API
-
Just a brief note to say I've approved the PR, but I stuffed up the CI pipeline in generating a Windows release. I ran out of time yesterday trying to find out a solution. I'll merge the PR once master is green again. I going to have to create a new releases branch, so that fixes for quirks on particular platforms are quarantined in that and not break the build for the master branch. I've learned my lesson.

I have integrated changes suggested by Gemini that supposedly tone down WM_PAINT message storms, and released it as 3.25.1. Could you please try this under zoom, and see if the freezes are still happening?
-
Good catch! I was wondering why this didn't bite us with Canvas event handling, but in that case, the PlotWidgets are manipulated through the Item interface, so it resolves correctly. But as you point out, with classdesc, the latest declaration trumps any earlier ones in the declaration stack, which means that the RenderNativeWindow intrerface (with the empty implementations) trumps the Item implementation. I think your proposed solution is the simplest, and probably most correct solution. Another...

Can't install Ravel
-
Yes, you are correct. This is on my laptop, so the last time I used it I must have done the Administrator install. I've just done the update and install with the latest beta, and there were no issues after I chose to install for just me.
-
Can't install Ravel
-
Clearly, you have installed Minsky as Administrator (All users). But when run it as a normal user, you won't have privileges to install the Ravel plugin in a system area. The most obvious solution is to uninstall "ravel" from the settings>apps dialog, then install it for just "current user". There is a new version out yesterday 3.24.0 that defaults to current user, and with no elevation, so you'd need to deliberately run the installer "as administrator" to install in a system location. 3.23.0 tried...

Interface Freeze

Any signs of the freezing in 2.23.0?

Under OOM conditions, Minsky attempts to save state to system location

OK so it did pop up eventually, but after minutes, not seconds.

Importing to database not popping up progress dialog

Bulk update of axis type doesn't work

All I can say is that it works for me. For the sake of the exercise, I started with 3.21.0, clicked upgrade, clicked through all the prompts, and it ended up with 3.23.0 with Ravel 2.1.9-pro. For reference, I used Windows 11, 25H2 build 26200.7840. Maybe try again, in case it was a temporary network glitch. You will notice I have disabled "one-click" installation, as I have been told that some some anti-malware systems flag one-click NSIS installers as potential malware. Ideally I'd like to switch...

The freezing doesn't appear to happen, but as you can see, I can't install Ravel.

I haven't got to that point yet because Ravel install fails--Minsky upgrades OK, but the install process fails-see screenshots. Movie to follow.
