From b67f689e4cb08ac3f33432038ae9aec81383a9f3 Mon Sep 17 00:00:00 2001 From: Mathias Fussenegger Date: Wed, 14 Apr 2021 21:29:32 +0200 Subject: lsp: Accept text document edits with version zero There were a couple of reports of "Buffer X newer than edits" problems. We first assumed that it is incorrect for a server to send 0 as a version - and stated that they should send a `null` instead, given that in the specification the `textDocument` of a `TextDocumentEdit` is a `OptionalVersionedTextDocumentIdentifier`. But it turns out that this was a change in 3.16, and in 3.15 and earlier versions of the specification it was a `VersionedTextDocumentIdentifier` and language servers didn't have a better option than sending `0` if they don't keep track of the version numbers. So this changes the version check to always accept `0` values.
