From 13c371dc10f8b5696b5728c9824d155ef9ad2f81 Mon Sep 17 00:00:00 2001 From: Patrick Steinhardt Date: Thu, 10 Mar 2016 17:21:02 +0100 Subject: [PATCH] config_cache: check return value of `git_config__lookup_entry` Callers of `git_config__cvar` already handle the case where the function returns an error due to a failed configuration variable lookup, but we are actually swallowing errors when calling `git_config__lookup_entry` inside of the function. Fix this by returning early when `git_config__lookup_entry` returns an error. As we call `git_config__lookup_entry` with `no_errors == false` which leads us to call `get_entry` with `GET_NO_MISSING` we will not return early when the lookup fails due to a missing entry. Like this we are still able to set the default value of the cvar and exit successfully. --- src/config_cache.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/src/config_cache.c b/src/config_cache.c index c859ec148..dbea871b9 100644 --- a/src/config_cache.c +++ b/src/config_cache.c @@ -86,7 +86,8 @@ int git_config__cvar(int *out, git_config *config, git_cvar_cached cvar) struct map_data *data = &_cvar_maps[(int)cvar]; git_config_entry *entry; - git_config__lookup_entry(&entry, config, data->cvar_name, false); + if ((error = git_config__lookup_entry(&entry, config, data->cvar_name, false)) < 0) + return error; if (!entry) *out = data->default_value;
