SIGSEV: mbedtls::Download - I believe you're accessing a non-allocated memory chunk?

This should explain it all:

I mimiced the mbedtls API in the scripting language, and -e executes a string. From thereon out, you should see where this is going :)

Enums within namespaces: Clang warning, C++11 feature

Whilst building, I encountered a warning several times - here is a snippet:

> ./ext/./minihttp/minihttp.cpp:37:44: warning: use of enumeration in a nested name specifier is a C++11 extension [-Wc++11-extensions]
>             {OS_TEXT("SSLR_OK"), minihttp::SSLResult::SSLR_OK},
>                                            ^

I was confused at first, but when I put the warning into google, I ended up here: http://lists.llvm.org/pipermail/cfe-commits/Week-of-Mon-20150112/121520.html
If you scroll down, you can see a testcase, which demonstrates this:

+namespace PR16951 {
+  namespace ns {
+    enum an_enumeration {
+      ENUMERATOR  // expected-note{{'ENUMERATOR' declared here}}
+    };
+  }
+
+  int x1 = ns::an_enumeration::ENUMERATOR; // expected-warning{{use of enumeration in a nested name specifier is a C++11 extension}}

So as it turns out, putting an enum into a namespace is C++11 and upwards. I myself was...well, surprised wouldn't suit it. But I would have assumed that naturally, anything can go into a namespace - turns out this is wrong.

So I'd like to ask for these enums to be moved upwards and renamed. It's just two anyway:

minihttp::SSLResult -> minihttp_SSLResult
minihttp::HttpCode -> minihttp_HttpCode

I am just suggesting these, but they would make the most sense, and allow non-C++11 compilers to not become confused :)

PolarSSL -> mbedTLS

https://tls.mbed.org/

Basically they changed names. This might affect this library. For backwards compatibility, I'd just suggest adding MINIHTTP_USE_MBEDTLS analogous to MINIHTTP_USE_POLARSSL.

Kind regards,
Ingwie

class DLSocket have a bug, always request memory and crash

(bufcap + size + 1 >= bufsz) changed to (bufsz + size + 1 >= bufcap)?

Direct way to download and buffer?

Hey.

I am trying to implement the download and buffer method. I.e.:

std::string mydata = ht->Download("http://google.com");

Kind regards, Ingwie

Got HTTP Status 401

I try minihttp::Download but I got http 401 status.

Got HTTP Status 401

How can I process it?
