From fc52cba32c6f8713160ed8838608d3d8a5f8a427 Mon Sep 17 00:00:00 2001 From: Emily Shaffer Date: Tue, 19 Nov 2019 16:39:54 -0800 Subject: [PATCH 1/5] help: move list_config_help to builtin/help Starting in 3ac68a93fd2, help.o began to depend on builtin/branch.o, builtin/clean.o, and builtin/config.o. This meant that help.o was unusable outside of the context of the main Git executable. To make help.o usable by other commands again, move list_config_help() into builtin/help.c (where it makes sense to assume other builtin libraries are present). When command-list.h is included but a member is not used, we start to hear a compiler warning. Since the config list is generated in a fairly different way than the command list, and since commands and config options are semantically different, move the config list into its own header and move the generator into its own script and build rule.

Later, Git can learn how to collect some diagnostic information from the repository. If users can send us a well-written bug report which contains diagnostic information we would otherwise need to ask the user for, we can reduce the number of question-and-answer round trips between the reporter and the Git contributor. Users may also wish to send a report like this to their local "Git expert" if they have put their repository into a state they are confused by.

By adding a generic get_compiler_info() in 'compat/' we can choose which relevant information to share per compiler; to get started, let's demonstrate the version of glibc if the user built with 'gcc'.
