Object Designer stucks in "Discovering Objects"

[elweilando]

Object Designer stucks in "Discovering Objects". The system gets slowy. After a couple of minutes visual studio code crashes.

Symbol can be downloaded without problems from server. .alcache will be created and include some json files.

Base Application v 15.1.37881.38071

Hi, thanks for the details!

I'll check it with above Base App version.

• Did you try deleting .alcache folder?
• Do you have - possibly big - symbols other than Base/System apps?
• Do you have "showStandardEvents" turned on? (If so, try turning it off)

[elweilando]

I have only the 3 default symbols

• Microsoft_Base Application_15.1.37881.38071
• Microsoft_System Application_15.1.37881.38071
• Microsoft_System_15.0.37898.0

I can delete .alcache. Directory will be created after starting Object Designer. showStandardEvents is turned off.

[elweilando]

I was able to reproduce it. In workspace settings "show standard events" was enabled. I overlooked this. After disable "show standard events" it works again.

[martonsagi]

Thanks for the feedback.

I'll remove that option to avoid further confusion. This setting is not required anymore as the new Event List serves its purpose better.

[martonsagi]

Note to self: remove showStandardEvents setting.

VS Code did crash too on my system. I think the problem might be caused by several *.app files of the same extension from different tested systems (e.g. 15.3, 16.0, etc.).

After I cleared my .alpackages folder, it still took some time (two seconds), but VS Code didn't crash. Maybe there should be an error thrown if the extension recognizes several .app files of the same extension?

[martonsagi]

Crash is likely due to the too big dataset in this case (duplicated objects from multiple app files). At the moment I filter out the same filenames across multiple projects but version number is not compared within filenames.

v0.1.5 is around the corner but I'll think of some warning to include before the final release.

[martonsagi]

So, my current solution is to pick a version to work with and give a warning at the same time as a reminder to clean up symbol files.

[martonsagi]

Note: the average dataset size that is sent to the WebView has been shrinked by ~24%. This should also speed up the loading a bit.

Delete the folder ".vscode.alcache"
