Loads forever and finally: "Cannot reconnect. Please reload the window."

[KolyaKorruptis]

I can run tasks via the command menu fine. But when I have Task Explorer enabled it loads forever and finally I get a pop-up: "Cannot reconnect. Please reload the window." This message only appears when I have Task Explorer enabled. I'm working on WSL and Task Explorer used to work fine with that. But since yesterday I've had to disable it,

[markkirchner]

The behaviour I get for the last few days is very similar: When trying to open the Task Explorer view, it "loads forever" and the view remains blank/empty the whole time. But in the end I get a popup saying "Extension host terminated unexpectedly" instead.

Additional info:

• While the Task Explorer view is showing the loading animation, there is a "Code.exe" process in the Windows task manager that shows a steadly increasing memory consumption (several GB in the end).
• I've enabled Extension Host profiling in VS Code which shows high "hitCount" values for several functions that seem to be related to Task Explorer (e.g. "taskTree.js"). If it helps, I can upload the profile dump as a gist or something.

[spmeesseman]

shit. there was a major overhaul in the release over the weekend. FOr now, you can install an old version in the Extension view of VSCode (elipses -> Install different version), not sure how that works though, and if you'd have to unset it to receive updates in the future. I'l look into it, Ive never used WSL, and in fact theres a few tickets open saying it never worked in WSL, Ive never tested it myself.

[spmeesseman]

aaahhh, i think i know what it might be. therell be a new releasrhis weekend, ill try to address this. for now seemy post above and you can install an older version

[spmeesseman]

for WSL, do you know if the user data folder is a remote folder? (where you would find your user tasks file tasks.json)

[spmeesseman]

also, please enable Task Explorer logging, turn the level all theway up, and restart. then send me that output from the Task Explorer output window

[KolyaKorruptis]

.vscode/tasks.json is inside the WSL container, always has been, never a problem. I set the debug level to 5. This is from the Output panel [Log: Remote Extension Host]:

[KolyaKorruptis]

Okay, I found the log you most likely meant: output-task-explorer.log

I installed version 1.29.0 which works fine. Getting back to the current version will be simple, since there's a button on the Task Explorer entry in extension view, to do so.

[GabbeV]

I believe I have the same issue. I'm not using WSL. I got it to not load forever by removing this line. Seems like the problem is that the tree is recursive for some reason.

[GabbeV]

The following .vscode/tasks.json in an otherwise empty folder recreates the issue for me:

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "foo",
            "type": "npm",
            "script": "start",
            "path": "foo/bar"
        },
        {
            "label": "bar",
            "type": "npm",
            "script": "start"
        }
    ]
}

Removing "path": "foo/bar" solves it.

[spmeesseman]

@GabbeV good find, thank you for sharing...

so turning off "Group by Separator" in settings "should" have the same effect as removing that line.

@KolyaKorruptis does turning off that setting resolve the issue for you? I think maybe two separate issues, but maybe not. I think for you, its a WSL thing, and I've added a new setting in 2.0 that will skip the code that I think is causing the problem. Once we verify that turning off that new setting in 2.0 does or does not fix your issue, we can go from there. Gonna work on and release 2,0 this weekend, I've had zero time to work on it this week, pretty busy at work all day every day. But let's see if what GabbeV found does anything for you first...

[GabbeV]

Turning off "Group with separator" seems to be a valid workaround for me 👍

[spmeesseman]

@GabbeV , i was looking at this tonight, I cant repro and I'm dumbfounded as to how the npm tasks without any separators in the label property are causing this. v2.0 is a major rebuild, so it may resolve this on accident, we'll see. can you reproduce it and post your log as explained in one of the posts above? and then when v2 comes out this weekend, afterwards if u can let me know if the new version behaves any differently for you I'd appreciate it. Thanks!

[KolyaKorruptis]

@spmeesseman Turning off "Group with separator" works for me on WSL2 in Task Explorer v1.30.2 👍

[GabbeV]

The issue seem to come from here. You add the subfolder to the list of files you are currently iterating over, causing you to add the subfolder to it self in the next iteration here. This creates a loop in the tree and anything trying to traverse the tree after that point will loop forever.

This tasks.json will recreate the issue as long as you have "Group with separator" turned on.

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "foo",
            "type": "npm",
            "script": "foo",
            "path": "some/path"
        },
        {
            "label": "bar",
            "type": "npm",
            "script": "bar",
            "path": "some/other/path"
        }
    ]
}

The important part is that they have different "path".

[spmeesseman]

well i think i have inadvertently fixed this in 2.0, because I cant reproduce no matter what. WIll release that tonight or tomorrow, if u guys can check on that again in a few days and let me know if its still an issue Id appreciate it, thanks for all the xtra info provided...

[GabbeV]

This issue is not fixed in version 2.0.2. The faulty code i pointed out in my last comment is still left here.

I fail to see how you can't reproduce the issue as I have tried it with a completely fresh installation of vscode with only this extension installed and all settings set to their defaults.

Here is a zip of a project that reproduce the issue. To reproduce the issue simply unpack the zip and open the folder named "task-explorer-bug" in vscode. task-explorer-bug.zip

[GabbeV]

Here is what goes wrong.

When entering createTaskGroupings the tree looks like this:

TaskFolder: workspacename
    TaskFile: source: vscode, path: some/path
        TaskItem: foo
    TaskFile: source: vscode, path: some/other/path
        TaskItem: bar

1. This loop starts iterating over the TaskFiles.
2. It finds 2 TaskFiles with the same source and decides to create a new subfolder.

3. The new subfolder is added to the list we are currently looping over making it the value of each in the next loop iteration.

   TaskFolder: workspacename
     TaskFile: source: vscode, path: some/path
         TaskItem: foo
     TaskFile: source: vscode, path: some/other/path
         TaskItem: bar
     TaskFile: source: vscode // new subfolder
         TaskFile: source: vscode, path: some/path
             TaskItem: foo
         TaskFile: source: vscode, path: some/other/path
             TaskItem: bar

4. This newly created subfolder also have the same source causing it to also get added to the subfolder(itself) creating a loop in the tree.

   TaskFolder: workspacename
     TaskFile: source: vscode, path: some/path
         TaskItem: foo
     TaskFile: source: vscode, path: some/other/path
         TaskItem: bar
     TaskFile: source: vscode <-- new subfolder
         TaskFile: source: vscode, path: some/path
             TaskItem: foo
         TaskFile: source: vscode, path: some/other/path    
             TaskItem: bar
         TaskFile: source: vscode <-- new subfolder
             TaskFile: source: vscode, path: some/path
                 TaskItem: foo
             TaskFile: source: vscode, path: some/other/path    
                 TaskItem: bar
             TaskFile: source: vscode <-- new subfolder
                 TaskFile: source: vscode, path: some/path
                     TaskItem: foo
                 TaskFile: source: vscode, path: some/other/path    
                     TaskItem: bar
                 TaskFile: source: vscode <-- new subfolder
                     ...recurse forever...

[spmeesseman]

what u keep pointing out to me is on purpose, I'm aware of where its coming from, but thank you for spending time looking at it. Its only happening to smoe users and I cant reproduce it as I said. With your same test params. ill look back into it one day after work this week...

[grloch]

I downgraded my installation to version 1.30.2 and it started to work again.

[spmeesseman]

yes, there's definitely a problem with 2.0 and workspace tasks that are type npm and/or have a path set. @grloch can you confirm you have these type of task definition(s) in your workspace?

v2.0.3 was let go tonight to fix a few reproducible issues, I found a core issue with the asynchronous approach that 2.0 uses. I don't think it will address this particular issue, but, can one of you guys test for me since I haven't been able to reproduce yet?

[mzimdars-gms-online-de]

Hi Scott, I don't know if I had exactly this issue (because there was never any error message 'at the end' because it never finished), but with your fix my issue is now gone :-) Thanks for your effort, the tool really helps a lot if you have many tasks to manage! Michael

[GabbeV]

@spmeesseman can you help me understand what is different in your attempt at reproducing the issue?

If you use the following tasks.json file and set a breakpoint right before removeGroupedTasks. What is the contents of the folder variable?

tasks.json:

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "foo",
            "type": "npm",
            "script": "foo",
            "path": "some/path"
        },
        {
            "label": "bar",
            "type": "npm",
            "script": "bar",
            "path": "some/other/path"
        }
    ]
}

For me it looks like this with the last TaskFile in scripts being infinitely recursive.

If yours is recursive like mine. What prevents removeScripts from calling itself forever?

is there any chance that these are the only two tasks in the workspace folder? no other npm tasks (in a package.json), etc, nothing else?
