From 9e9de18f1ad39901a8f0c67f0af70d66d427e326 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Mon, 24 Aug 2015 02:11:33 -0400 Subject: config: silence warnings for command names with invalid keys When we are running the git command "foo", we may have to look up the config keys "pager.foo" and "alias.foo". These config schemes are mis-designed, as the command names can be anything, but the config syntax has some restrictions. For example: $ git foo_bar error: invalid key: pager.foo_bar error: invalid key: alias.foo_bar git: 'foo_bar' is not a git command. See 'git --help'. You cannot name an alias with an underscore. And if you have an external command with one, you cannot configure its pager. In the long run, we may develop a different config scheme for these features. But in the near term (and because we'll need to support the existing scheme indefinitely), we should at least squelch the error messages shown above. These errors come from git_config_parse_key. Ideally we would pass a "quiet" flag to the config machinery, but there are many layers between the pager code and the key parsing. Passing a flag through all of those would be an invasive change. Instead, let's provide a config function to report on whether a key is syntactically valid, and have the pager and alias code skip lookup for bogus keys. We can build this easily around the existing git_config_parse_key, with two minor modifications: 1. We now handle a NULL store_key, to validate but not write out the normalized key. 2. We accept a "quiet" flag to avoid writing to stderr. This doesn't need to be a full-blown public "flags" field, because we can make the existing implementation a static helper function, keeping the mess contained inside config.c.
