Roslyn: Non catchable errors with SimpleTagger

Created on 29 May 2017 · 13Comments · Source: dotnet/roslyn

I'm working on CodeLens for Visual F# and faced two errors I cannot catch.
See PR https://github.com/Microsoft/visualfsharp/pull/2967#issuecomment-304667007
(currently closed due to _this_ bug)

First error:

Reproduction
I have a gif showing how to reproduce the first error with my PR.
codelensfail

Unfortunately I cannot reproduce everytime again but I know it's reproduced the same way as with the first error. I suppose it's connected.

Expected Behavior:
Well no errors :smile:

Actual Behavior:
Errors which aren't catchable at all and shutdown VS.

This likely indicates there was an exception thrown during text view layout that left it in a bad state. Try these two options:

Run under debugger and see if there is any exception thrown (particularly in LayoutChanged event handler).
Or grab and share a memory dump, the exception is stored in some text view field and I can check if it's there.

olegtk on 30 May 2017

@olegtk according the ObjectDisposed exception. I might have now different code which reproduces this without usage of SimpleTagger.

please look into this branch.
https://github.com/realvictorprm/visualfsharp/tree/bug2

Short explanation:
I tried implementing an own simple tagger and create a general code lens class. This is the result. However, usage of this might result in object disposed exceptions.

realvictorprm on 1 Jun 2017

My point is that both exceptions you post here are probably the result of a text view being in a bad state, which in the first place was caused by another, probably swallowed exception.
Please grab and share a memory dump taken after you reproduce this error.

olegtk on 1 Jun 2017

@olegtk Sorry, I have been busy and in a worse mood. I'll look now into the code again look for further reasons and create also memory dumps.

realvictorprm on 17 Jun 2017

I think it might be a bug with the SpaceNegotiatingAdornmentTag. I'm currently uploading the memory dump, takes a lot time because it's even compressed still huge.

realvictorprm on 17 Jun 2017

@olegtk memory dump is here

realvictorprm on 17 Jun 2017

Any updates?

realvictorprm on 22 Jun 2017

Yep, the dump contains the original exception that left text view in a bad state, but it doesn't explain much either :( It's ArgumentOutOfRangeException in Microsoft.VisualStudio.Text.Span(int start , int length) constructor thrown here: https://github.com/Microsoft/vs-editor-api/blob/master/src/Text/Def/TextData/Model/Span.cs#L40

if (start + length < start)
{
throw new ArgumentOutOfRangeException("length");
}

That likely means your space negotiating adornment is created with incorrect span start/length that either negative or too large.

Can you please set VS debugger to break at ArgumentOutOfRangeException, repeat the repro and grab a dump when this exception is thrown?

olegtk on 22 Jun 2017

@olegtk I'll start documenting here:

In the FsiCommandService.fs; line 49, I've got System.ArgumentException: "Der angegebene SnapshotPoint befindet sich in einer falschen Momentaufnahme.
(In english: "SnapshotPoint is in the wrong snapshot version")
After this exception I'm getting the System.ObjectDisposedException: "Auf das verworfene Objekt kann nicht zugegriffen werden.

realvictorprm on 22 Jun 2017

cc @olegtk

Unfortunately there isn't any ArgumentOutOfRangeException being thrown, only ArgumentException according that the SnapshotPoint is in the wrong state.

@cartermp is this a known error?

happens both in script and non-script files.
