Hmmmm.

$ git grep -A1 config_error_nonbool | grep -B1 '^[^ ]*-.* = xstrdup'

shows these 13:

alias.c:			return config_error_nonbool(k);
alias.c-		alias_val = xstrdup(v);
--
builtin-apply.c:			return config_error_nonbool(var);
builtin-apply.c-		apply_default_whitespace = xstrdup(value);
--
builtin-commit.c:			return config_error_nonbool(v);
builtin-commit.c-		template_file = xstrdup(v);
--
builtin-log.c:			config_error_nonbool(var);
builtin-log.c-		fmt_patch_subject_prefix = xstrdup(value);
--
builtin-log.c:			return config_error_nonbool(var);
builtin-log.c-		fmt_patch_suffix = xstrdup(value);
--
config.c:		return config_error_nonbool(var);
config.c-	*dest = xstrdup(value);
--
diff.c:			return config_error_nonbool(var);
diff.c-		external_diff_cmd_cfg = xstrdup(value);
--
http.c:				return config_error_nonbool(var);
http.c-			ssl_cert = xstrdup(value);
--
http.c:				return config_error_nonbool(var);
http.c-			ssl_key = xstrdup(value);
--
http.c:				return config_error_nonbool(var);
http.c-			ssl_capath = xstrdup(value);
--
http.c:				return config_error_nonbool(var);
http.c-			ssl_cainfo = xstrdup(value);
--
http.c:				return config_error_nonbool(var);
http.c-			curl_http_proxy = xstrdup(value);
--
remote.c:				return config_error_nonbool(key);
remote.c-			branch->remote_name = xstrdup(value);

Among these, obviously the one in config.c cannot be replaced (it is the
implementation of git_config_string() itself ;-), and the one in remote.c
has a different pattern (it does not return immediately after that, but
everything else can be mechanically replaced.

I also have strong doubt about the way http.c handles duplicated
configuration values; everybody else let's the later one override the
previous one, while these take and keep the first occurrence.  I left the
logic of them as they were, because changing them would change the
semantics of the program.

Hi,

a simple `Janitor patch'.

Thanks.

Junio, please apply.

Hmmmm.

$ git grep -A1 config_error_nonbool | grep -B1 '^[^ ]*-.* = xstrdup'

shows these 13:

Yes, there are many potential places.

Among these, obviously the one in config.c cannot be replaced (it is the
implementation of git_config_string() itself ;-), and the one in remote.c
has a different pattern (it does not return immediately after that, but
everything else can be mechanically replaced.

I think that each case should be looked at closely. But as it's not very 
difficult either in many cases, I think it's a good thing to let newbies 
try their skills at it. That's why I set up the Janitor page on the wiki:

http://git.or.cz/gitwiki/Janitor

describing this task.

That's also the patch that Stephan sent to the list before, see:

http://thread.gmane.org/gmane.comp.version-control.git/78845

And I told him that casting to (const char **) was ugly, and it was better 
to leave this file as it is.

That's the next patch Stephan sent, and it is indeed good, so please apply 
Stephan's. Thanks.

About other files, I don't care much. That's also why I left it to Janitors.

If I see that you fixed everything I will just remove the Janitor page on 
the wiki.

Christian.
