""" - It needlessly used the makefile() method for each response that is read from the SMTP server. - If the remote SMTP server closes the connection unexpectedly the code raised an IndexError. It now raises an SMTPServerDisconnected exception instead. - The code now checks that all lines in a multiline response actually contains an error code. """ The Dragon approves.

frozen_dllmain.c
/* FreezeDLLMain.cpp
This is a DLLMain suitable for frozen applications/DLLs on
a Windows platform.
The general problem is that many Python extension modules may define
DLL main functions, but when statically linked together to form
a frozen application, this DLLMain symbol exists multiple times.
The solution is:
* Each module checks for a frozen build, and if so, defines its DLLMain
function as "__declspec(dllexport) DllMain%module%"
(eg, DllMainpythoncom, or DllMainpywintypes)
* The frozen .EXE/.DLL links against this module, which provides
the single DllMain.
* This DllMain attempts to locate and call the DllMain for each
of the extension modules.
* This code also has hooks to "simulate" DllMain when used from
a frozen .EXE.
At this stage, there is a static table of "possibly embedded modules".
This should change to something better, but it will work OK for now.
Note that this scheme does not handle dependencies in the order
of DllMain calls - except it does call pywintypes first :-)
As an example of how an extension module with a DllMain should be
changed, here is a snippet from the pythoncom extension module.
// end of example code from pythoncom's DllMain.cpp
#ifndef BUILD_FREEZE
#define DLLMAIN DllMain
#define DLLMAIN_DECL
#else
#define DLLMAIN DllMainpythoncom
#define DLLMAIN_DECL __declspec(dllexport)
#endif
