Slow starting/refreshing of debug session in Chrome

[mikij]

When I am using debug.chrome.useV3: true then debug session took several minutes to just start Angular based application. Any update of code means reload of application which means another wait session. So I am forced to not use V3 for debugging even to try it. I noticed that break points also is not bound so for now this new debugger seems completely usefulness for browser debugging. If you have any suggestions I could try. Official version of debugger works normally for me.

Please add trace: true to your launch config and share the logs here. Also, if what you're working on happens to be open source, a link to its repo would be helpful as well. Thanks!

[mikij]

I will try because I am working in Amazon Workspaces environment that I don't have possibility to take out anything. But I think they will let me share those logs here.

[mikij]

You want logs from moment I start debug session until login screen shows up, right?

[connor4312]

Yep, that would be ideal. Note that the log files do contain file paths. If there are concerns sharing them publicly here, you can also email them to me at copeet at microsoft.com.

[mikij]

Well this is what I got in Debug Console output

Also there is a json file in /tmp folder that is about 648 MB big. Is that log file you need?

[connor4312]

Yep. That's pretty large, you can compress it before you send it--it should compact down fairly well.

[mikij]

Okay I asked for approval. Once it would approved or disapproved I will let you know.

I have the same problem, check out my

Thanks for the log. I think I know what's happening here. @FishOrBear can you set/add devtool: "source-map" to your webpack configuration and let me know if that fixes it for you?

Isn't that set by Angular for webpack configuration automatically if we just set sourceMap to true in angular.json?

[FishOrBear]

My project is not Angular.
Is Webpack + Typescript + React.

The original first log used devtool: "eval-source-map"
The following logs use "source-map"

[connor4312]

Thanks for the report. I've submitted a PR with a fix that seems to work well in my testing. Here's a build of the extension with the fix if you'd like to take it for a spin before it gets merged

You can install it using Install from VSIX command in vs code

Looks good, i have used it

@connor4312

HMR will have problems

For my case this is even worse. Now my app won't start at all or at least it needs much more time to start than before. Actually when I turned on Chrome's dev tools I saw it is still loading but process is too much slower now. Sorry for bringing up bad news. They are so keen to allow me to send my log file to you. But I will try push once more.

[FishOrBear]

@mikij I can't use it now. Temporarily use Debugger for Chrome4.11.7

[mikij]

I am using the old Debugger for Chrome all the time while I am waiting for any proper fix for new one to give it a try.

@FishOrBear

[connor4312]

Thanks for letting me know. I'm guessing that something in your setup is different and not triggering the detection that I added to take the fast path for these kinds of bundles.

It may be easier to get approval to send part of the file. In the logs, you should see a very large number of lines containing the string "Debugger.paused". If you can send a sample of these events to me, that should provide enough information to fix up the logic.
