Document encoding can throw in SourceTextStream.Read #24845

Open miloush opened 6 years ago

miloush commented 6 years ago

Version Used: 15.6 Preview 5 / 2.7.0.62608

  1. Enable the Gothic input language. Note this is not an out of BMP issue, but makes the repro easier.
  2. Create a new console application.
  3. Type any letter on the Gothic keyboard into the code, for example to replace the main method name.

Visual Studio crashes. (Also an extension might throw an UriFormatException in activity log #19542).

If the crash does not occur, use Advanced save options to ensure the document is saved in some ANSI, non-Unicode encoding (which is sadly the default) before step 3.

The SourceTextStream uses document's throwing encoding if available, for text that has potentially not been stored in that encoding. If a file cannot be saved in a codepage, Visual Studio either automatically or after prompt saves the document in Unicode (depending on Options > Environment > Documents > Save documents as Unicode when data cannot be saved in codepage). All operations on unsaved text data (code analysis, background compilation, etc.) should not use the encoding of dirty files since the unsaved text might not be valid in that encoding.

I could not find multiple crashes or faults in Watson analytics. Therefore, moved it to 16.0.

miloush commented 6 years ago

Yes, you get UriFormatException as NFW - that's an unrelated bug, similar to #19542.

I can still reproduce the crash on 15.8 Preview 3, except that the default encoding at least of C# code files seems to have been changed to UTF-8, which is exciting!

Anyway, to reproduce the crash, either open an existing C# file that wasn't saved with Unicode encoding, or, create a new C# console project, and use Advance Saving Options to change the file encoding to Codepage 1252 or similar, save the document and replace the word Main with 𐌸 (you can paste it).

sandyarmstrong commented 4 years ago

This looks similar to an exception we sometimes see in VSmac (hit by a few hundred users):

I18N.CJK.GB18030Encoder.GetBytes(Char[],Int32,Int32,Byte[],Int32,Boolean)

jeffgoku commented 3 years ago

same issue here in VS mac, using find all reference will throw this exception. Im using the latest VS, but works ok in the previous edition 8.6

KirillOsenkov commented 3 years ago

@jinujoseph we are having lots of reports of VSMac crashing due to this issue (see internal ticket https://dev.azure.com/devdiv/DevDiv/_workitems/edit/1168824). Would it be possible to please prioritize this?

jinujoseph commented 3 years ago

@KirillOsenkov seems like an old issue? or did it aggravated recently?

KirillOsenkov commented 3 years ago

@jinujoseph See the internal issue I mentioned above for details

jasonmalinowski commented 3 years ago

The InvalidOperationException coming from I18N.CJK.GB18030Encoder.GetBytes(Char[],Int32,Int32,Byte[],Int32,Boolean) looks like it could be this mono bug that may have just been fixed: https://github.com/mono/mono/pull/20522

KirillOsenkov commented 3 years ago

Ah, right, that is probably it. We have just inserted that build of Mono (thanks @mrward).

@jbevain FYI this might be fixed with a Mono bump.

This original Roslyn issue might be a separate issue then?

jasonmalinowski commented 3 years ago

Yes, the original issue looks to be something entirely different.

jasonmalinowski commented 3 years ago

And to make this bug not be confusing: the stuff related to GB18030Encoder I'm going to mark off topic. Not that it wasn't a good conversation but it's unrelated to the original issue (or, at least, I expect the fix to be fundamentally different). I'll move it back to the backlog from whence this bug came so whoever looks at it next doesn't get confused.

Youssef1313 commented 3 years ago

Is this the same as https://github.com/dotnet/roslyn/issues/49053, which got fixed?

miloush commented 3 years ago

@Youssef1313 no that one is when creating URI, this one is when saving file (either explicitly or for the purpose of background tasks).
