This limits all accepted input strings passed to libcurl to be less than CURL_MAX_INPUT_LENGTH (1000000) bytes, for these API calls: curl_easy_setopt() and curl_url_set(). The 1000000 number is arbitrary picked and is meant to detect mistakes or abuse, not to limit actual practical use cases. By limiting the acceptable string lengths we also reduce the risk of integer overflows all over. NOTE_ This does not apply to `CURLOPT_POSTFIELDS`.

No objections have been received, but I bump the limit to 8000000 bytes anyway to reduce the risk of hitting a valid use case further. |
