# [PATCH v2] connect.c: add a way for git-daemon to pass an error back to client 1 messages from 2008-11-01 to 2008-11-01. Participants: Tom Preston-Werner. Thread: https://gitlist.dev/t/16121 ## Tom Preston-Werner, 2008-11-01 18:44 Subject: [PATCH v2] connect.c: add a way for git-daemon to pass an error back to client Message-ID: URL: https://gitlist.dev/e/b97024a40811011144s7f4bca47w1cc92b0975cecbc5%40mail.gmail.com ``` The current behavior of git-daemon is to simply close the connection on any error condition. This leaves the client without any information as to the cause of the failed fetch/push/etc. This patch allows get_remote_heads to accept a line prefixed with "ERR" that it can display to the user in an informative fashion. Once clients can understand this ERR line, git-daemon can be made to properly report "repository not found", "permission denied", or other errors. Example S: ERR No matching repository. C: fatal: remote error: No matching repository.
