patch 9.0.1939: still a problem when processing LSP RPC requests Commit: https://github.com/vim/vim/commit/b80ae6cec34639abfb1a7080fb633346a81a5770 Author: Yegappan Lakshmanan <yegappan@yahoo.com> Date: Sun Sep 24 23:38:46 2023 +0200 patch 9.0.1939: still a problem when processing LSP RPC requests Problem: still a problem when processing LSP RPC requests Solution: When processing async LSP RPC requests, compare sequence numbers only in response messages A LSP request message can be sent to the language server either synchronously (ch_evalexpr) or asynchronously (ch_sendexpr). In both cases, when looking for response messages by using the sequence number, LSP requests messages from the language server with the same sequence number should not be used. Patch 9.0.1927 fixed this issue for synchronous requests. This PR fixes the issue for asynchronous requests and adds additional tests. closes: #13158 Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: Yegappan Lakshmanan <yegappan@yahoo.com>
