Adding additional parse checking logic

[sergior2]

   “Project” means any of the projects owned or managed by Microsoft and offered under a license
   approved by the Open Source Initiative (www.opensource.org).
   “Submit” is the act of uploading, submitting, transmitting, or distributing code or other content to any
   Project, including but not limited to communication on electronic mailing lists, source code control
   systems, and issue tracking systems that are managed by, or on behalf of, the Project for the purpose of
   discussing and improving that Project, but excluding communication that is conspicuously marked or
   otherwise designated in writing by You as “Not a Submission.”
   “Submission” means the Code and any other copyrightable material Submitted by You, including any
   associated comments and documentation.
2. Your Submission. You must agree to the terms of this Agreement before making a Submission to any
   Project. This Agreement covers any and all Submissions that You, now or in the future (except as
   described in Section 4 below), Submit to any Project.
3. Originality of Work. You represent that each of Your Submissions is entirely Your original work.
   Should You wish to Submit materials that are not Your original work, You may Submit them separately
   to the Project if You (a) retain all copyright and license information that was in the materials as You
   received them, (b) in the description accompanying Your Submission, include the phrase “Submission

4. Your Employer. References to “employer” in this Agreement include Your employer or anyone else
   for whom You are acting in making Your Submission, e.g. as a contractor, vendor, or agent. If Your
   Submission is made in the course of Your work for an employer or Your employer has intellectual
   property rights in Your Submission by contract or applicable law, You must secure permission from Your
   employer to make the Submission before signing this Agreement. In that case, the term “You” in this
   Agreement will refer to You and the employer collectively. If You change employers in the future and
   desire to Submit additional Submissions for the new employer, then You agree to sign a new Agreement
   and secure permission from the new employer before Submitting those Submissions.
5. Licenses.

  indirectly from Microsoft, a perpetual, worldwide, non-exclusive, royalty-free, irrevocable license in the
  Submission to reproduce, prepare derivative works of, publicly display, publicly perform, and distribute
  the Submission and such derivative works, and to sublicense any or all of the foregoing rights to third
  parties.
• Patent License. You grant Microsoft, and those who receive the Submission directly or
  indirectly from Microsoft, a perpetual, worldwide, non-exclusive, royalty-free, irrevocable license under
  Your patent claims that are necessarily infringed by the Submission or the combination of the
  Submission with the Project to which it was Submitted to make, have made, use, offer to sell, sell and
  import or otherwise dispose of the Submission alone or with the Project.
• Other Rights Reserved. Each party reserves all rights not expressly granted in this Agreement.
  No additional licenses or rights whatsoever (including, without limitation, any implied licenses) are

   employer or Your employer has intellectual property rights in Your Submission by contract or applicable
   law. If You are signing this Agreement on behalf of Your employer, You represent and warrant that You
   have the necessary authority to bind the listed employer to the obligations contained in this Agreement.

Can this just be?

Suggested change

	return !this.model.isInitializingWorkspace.Value
	&& !this.model.isIndexingWorkspace.Value
	&& !this.model.isParsingWorkspace.Value
	&& !this.model.isParsingFiles.Value
	&& !this.model.isUpdatingIntelliSense.Value;
	return !this.IsTagParsing() && !this.model.isUpdatingIntelliSense.Value;

Nit: you didn't introduce this, but since all these properties being checked belong to this.model, I might expect there to be a ClientModel.IsIdle(): bool or something.

[sergior2]

Will add the suggested change, although I'm not sure I follow when you say there to be a ClientModel.IsIdle()?

Is that not what isIdle() currently fulfilling?

[bobbrow]

He's saying add a public method on ClientModel instead of DefaultClient. Though there is already DefaultClient.IsTagParsing which I think is what you care about. isUpdatingIntelliSense wasn't what I thought you wanted to block on. So it looks like the property you want already exists.

[bobbrow]

You don't actually need to check for "idle" right? I thought you just wanted to know when tag parsing is done.

[sean-mcmanus]

Yeah, I would think the IsTagParsing should be sufficient.

[sean-mcmanus]

It appears our status indicator is per-workspace folder, so it seems like this won't work for workpace folders > than the 1st.

[sean-mcmanus]

This seems strange though...might be a pre-existing problem. It seems like the status indicator should be shared among all workspace folders.

[sean-mcmanus]

Maybe you can wait for all for all the clients? Instead of just the default.

[sean-mcmanus]

Maybe something like this generated by Copilot:

    const waitForIdlePromises: Promise<boolean>[] = [];
    clients.forEach(client => {
        waitForIdlePromises.push(client.waitForIdle(timeout));
    });

    const waitForIdleResults: boolean[] = await Promise.all(waitForIdlePromises);
    return waitForIdleResults.every(result => result);

[sean-mcmanus]

But having the status be per-workspace folder doesn't really make sense -- but no one has complained yet as far as I know. i.e. there could be bugs/issues with that, not sure, when switching to file in a different workspace, I see the status be "incorrect" (i.e. idle instead of processing).

[sergior2]

I originally had this implemented as the following:

    const pending: Promise<boolean>[] = [];
    clients.forEach(client => pending.push(client.waitForIdle(timeout)));
    const results: boolean[] = await Promise.all(pending); 1
    return results.every(result => result);

But was told that only reports status notifications to the 1st client, and advised instead to use getDefaultClient. Would this not bind the notifications across?

[sergior2]

Sorry for the late reply, comments were not updating on my end for some reason

[sean-mcmanus]

What? Yeah, it seems like you should waitForIdle across all clients. I'm seeing them per-client, although that is probably a pre-existing issue as mentioned previously.

[carsonRadtke]

Consider moving these checks "up" to the command handler and changing the signature to waitForIdle(timeout: number).

Also, if devtools (or whoever calls this) supplies an invalid timeout, maybe we raise an exception instead of returning false?

[sergior2]

Fixed
