The name "maxlen" captures the "longest" part, but "has matched" is somehow lost. Can we have a better name here please, or at least a comment to clarify what this variable keeps track of. > static int curl_ssl_verify = -1; > static int curl_ssl_try; > static const char *ssl_cert; > @@ -141,34 +169,99 @@ static void process_curl_messages(void) > } > #endif > > +static int http_options_url_match_prefix(const char *url, const char *url_prefix) > +{ > + /* > + * url_prefix matches url if url_prefix is an exact match for url or it > + * is a prefix of url and the match ends on a path component boundary. > + * url_prefix is considered to have an implicit '/' on the end for > + * matching purposes if it does not already and it is shorter than url. > + * the return value is the length of the match in characters (excluding > + * any final '/') or 0 for no match. > + */ > + size_t url_len, url_prefix_len = strlen(url_prefix); > + if (!url_prefix_len || strncmp(url, url_prefix, url_prefix_len)) > + return 0; Should "url=http://git.or.xz/git"; match "url_prefix=http://git.or.xz/git/";? > + url_len = strlen(url); > + if (url_len == url_prefix_len || url[url_prefix_len - 1] == '/' || url[url_prefix_len] == '/') > + return url[url_prefix_len - 1] == '/' ? url_prefix_len - 1 : url_prefix_len; Overlong lines that are somewhat hard to read. > + return 0; > +} > + > static int http_options(const char *var, const char *value, void *cb) > { > - if (!strcmp("http.sslverify", var)) { > +/* > + * Macro to ignore matches with a match length less than previously seen > + * for the same option type and to remember the largest match length seen so > + * far for each option type > + */ > +#define CHECK_MATCHLEN(opt) \ > + if (http_option_maxlen[opt] > matchlen) return 0; \ > + else http_option_maxlen[opt] = matchlen Avoid defining a macro _inside_ a function.
