Opening too large file crashes Viper IDE

[Pointerbender]

When opening files in Viper IDE that are (too) large, the Viper server throws an exception and this breaks Viper IDE so that it gives up permanently and a VS code restart is required.

The error that I'm getting is:

node:events:368
      throw er; // Unhandled 'error' event
      ^

Error: Parser cannot parse input: expected a value

It looks like the default (internal) buffer used by vscode-languageserver/node-ipc to store IPC messages is not large enough to hold the file contents. I tried adjusting the viperSettings.advancedFeatures.verificationBufferSize to something larger, but this didn't help, because this buffer isn't instantiated until after the IPC message has been fully received, it seems.

viper-ide/server/src/server.ts

Line 49 in e4c7317

Server.connection = createConnection(new IPCMessageReader(process), new IPCMessageWriter(process));

Seems to be fixed by #113. Please reopen and attach such a file if the problem persists with the latest pre-release
