From aac0e8ffeeed57cae2a047fd442f2125cbfc8e39 Mon Sep 17 00:00:00 2001 From: Victoria Dye Date: Fri, 12 Aug 2022 20:10:17 +0000 Subject: [PATCH] builtin/bugreport.c: create '--diagnose' option MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Create a '--diagnose' option for 'git bugreport' to collect additional information about the repository and write it to a zipped archive. The '--diagnose' option behaves effectively as an alias for simultaneously running 'git bugreport' and 'git diagnose'. In the documentation, users are explicitly recommended to attach the diagnostics alongside a bug report to provide additional context to readers, ideally reducing some back-and-forth between reporters and those debugging the issue. Note that '--diagnose' may take an optional string arg (either 'stats' or 'all'). If specified without the arg, the behavior corresponds to running 'git diagnose' without '--mode'. As with 'git diagnose', this default is intended to help reduce unintentional leaking of sensitive information). Users can also explicitly specify '--diagnose=(stats|all)' to generate the respective archive created by 'git diagnose --mode=(stats|all)'.
