Error: Could not send to validation process, uri is not indexed: /home/xxx/1.sol

Sentry Issue: VSCODE-EXTENSION-W5V

Reported by @OmarTawfik:

!title:"Error: Could not send to validation process, uri is not indexed and Error: Could not analyze, uri is not indexed. Reading the code, looks to me like it rejects indexing files that are not on disk yet (temporary VS Code editor/buffer?). Since this is also not actionable, should we index the editor in-memory contents? or if non-trivial, should we keep tracking this as an error if it is a known limitation?

We should look again at the check that throw this error. If we do not expect to index in-memory editor files, then we should not report those to sentry - instead checking they are in-memory before hand and avoiding the index lookup. Or if in-memory contents should be in the index, what do we need to change?

@antico5 this is likely new files that have been opened but never saved, so they haven't triggered a create event with a uri, right?

[Armando Andini]

I just tested with new, unsaved files, and we don't get validation on those but we also don't throw any errors. I also tried opening a single file from outside the workspace and it works as expected.

I can't really tell what the reason could be. When a file is requested validation, if it's not present in the index, it is indexed and the process continues.

@antico5 thanks for checking. I suggested that because of this logic in indexSolidityFile() which is called from services/validation/validate.ts:

hardhat-vscode/server/src/services/initialization/indexWorkspaceFolders.ts

Lines 168 to 175 in 9cfb24b

 export async function indexSolidityFile( 
   serverState: ServerState, 
   fileUri: string 
 ) { 
   if (!(await serverState.workspaceFileRetriever.isFile(fileUri))) { 
     return; 
   } 
  

And isFile() in turn just checks the local FS:

hardhat-vscode/server/src/utils/WorkspaceFileRetriever.ts

Lines 38 to 44 in 9cfb24b

 public async isFile(fsPath: string) { 
   try { 
     return (await fs.promises.stat(fsPath)).isFile(); 
   } catch (error) { 
     return false; 
   } 
 }
