Prior to 1f2baa7 (config: treat non-existent config files as empty, 2010-10-21), we returned an error if any config files were missing. That commit made this a non-error, but returned the number of sources found, in case any caller wanted to distinguish this case. In the past 5+ years, no caller has; the only two places which bother to check the return value care only about the error case. Let's drop this code, which complicates the function. Similarly, let's drop the "found anything" return from git_config_from_parameters, which was present only to support this (and similarly has never had other callers care for the past 5+ years). Note that we do need to update a comment in one of the callers, even though the code immediately below it doesn't care about this case. Signed-off-by: Jeff King <peff@xxxxxxxx> --- This technically changes the function interface without breaking compilation for any topics in flight. But given the history, and that the now-unhandled case is not actually _useful_, I don't think it's worth worrying about. config.c | 34 +++++++++------------------------- 1 file changed, 9 insertions(+), 25 deletions(-) diff --git a/config.c b/config.c index 096fe03..3f8f6aa 100644 --- a/config.c +++ b/config.c @@ -230,7 +230,7 @@ int git_config_from_parameters(config_fn_t fn, void *data) free(argv); free(envw); - return nr > 0; + return 0; } static int get_next_char(void) @@ -1201,47 +1201,31 @@ int git_config_system(void) static int do_git_config_sequence(config_fn_t fn, void *data) { - int ret = 0, found = 0; + int ret = 0; char *xdg_config = xdg_config_home("config"); char *user_config = expand_user_path("~/.gitconfig"); char *repo_config = git_pathdup("config"); - if (git_config_system() && !access_or_die(git_etc_gitconfig(), R_OK, 0)) { + if (git_config_system() && !access_or_die(git_etc_gitconfig(), R_OK, 0)) ret += git_config_from_file(fn, git_etc_gitconfig(), data); - found += 1; - } - if (xdg_config && !access_or_die(xdg_config, R_OK, ACCESS_EACCES_OK)) { + if (xdg_config && !access_or_die(xdg_config, R_OK, ACCESS_EACCES_OK)) ret += git_config_from_file(fn, xdg_config, data); - found += 1; - } - if (user_config && !access_or_die(user_config, R_OK, ACCESS_EACCES_OK)) { + if (user_config && !access_or_die(user_config, R_OK, ACCESS_EACCES_OK)) ret += git_config_from_file(fn, user_config, data); - found += 1; - } - if (repo_config && !access_or_die(repo_config, R_OK, 0)) { + if (repo_config && !access_or_die(repo_config, R_OK, 0)) ret += git_config_from_file(fn, repo_config, data); - found += 1; - } - switch (git_config_from_parameters(fn, data)) { - case -1: /* error */ + if (git_config_from_parameters(fn, data) < 0) die(_("unable to parse command-line config")); - break; - case 0: /* found nothing */ - break; - default: /* found at least one item */ - found++; - break; - } free(xdg_config); free(user_config); free(repo_config); - return ret == 0 ? found : ret; + return ret; } int git_config_with_options(config_fn_t fn, void *data, @@ -1276,7 +1260,7 @@ static void git_config_raw(config_fn_t fn, void *data) if (git_config_with_options(fn, data, NULL, 1) < 0) /* * git_config_with_options() normally returns only - * positive values, as most errors are fatal, and + * zero, as most errors are fatal, and * non-fatal potential errors are guarded by "if" * statements that are entered only when no error is * possible. -- 2.8.2.888.gecb1fe3 -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
