* Refactor git module, make Gitea use internal git config, add safe.directory config * introduce git.InitSimple and git.InitWithConfigSync, make serv cmd use gitconfig * use HOME instead of GIT_CONFIG_GLOBAL, because git always needs a correct HOME * fix cmd env in cmd/serv.go * fine tune error message * Fix a incorrect test case * fix configAddNonExist * fix configAddNonExist logic, add `--fixed-value` flag, add tests * add configSetNonExist function in case it's needed. * use configSetNonExist for `user.name` and `user.email` * add some comments * Update cmd/serv.go Co-authored-by: zeripath <art27@cantab.net> * Update cmd/serv.go Co-authored-by: zeripath <art27@cantab.net> * Update modules/git/git.go Co-authored-by: zeripath <art27@cantab.net> * Update modules/setting/setting.go Co-authored-by: zeripath <art27@cantab.net> * Update modules/git/repo_attribute.go Co-authored-by: zeripath <art27@cantab.net> * fix spaces in messages * use `configSet("core.protectNTFS", ...)` instead of `globalCommandArgs` * remove GIT_CONFIG_NOSYSTEM, continue to use system's git config * Update cmd/serv.go Co-authored-by: zeripath <art27@cantab.net> * fix merge * remove code for safe.directory * separate git.CommonEnvs to CommonGitCmdEnvs and CommonCmdServEnvs * avoid Golang's data race error Co-authored-by: zeripath <art27@cantab.net> Co-authored-by: Lunny Xiao <xiaolunwen@gmail.com>
