http_proxy: do not crash with HTTPS_PROXY and NO_PROXY set
... in case NO_PROXY takes an effect Without this patch, the following command crashes: $ GIT_CURL_VERBOSE=1 NO_PROXY=github.com HTTPS_PROXY=https://example.com \ git clone https://github.com/curl/curl.git Minimal libcurl-based reproducer: #include <curl/curl.h> int main() { CURL *curl = curl_easy_init(); if(curl) { CURLcode ret; curl_easy_setopt(curl, CURLOPT_URL, "https://github.com/"); curl_easy_setopt(curl, CURLOPT_PROXY, "example.com"); /* set the proxy type */ curl_easy_setopt(curl, CURLOPT_PROXYTYPE, CURLPROXY_HTTPS); curl_easy_setopt(curl, CURLOPT_NOPROXY, "github.com"); curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L); ret = curl_easy_perform(curl); curl_easy_cleanup(curl); return ret; } return -1; } Assisted-by: Kamil Dudka Bug: https://bugzilla.redhat.com/1873327 Closes #5902
