Re: svn commit: r1748461 - in /httpd/httpd/branches/2.2.x: ./ CHANGES support/ab.c

Great, I'll proceed with changing ab.c to remove the hack, since it is unneeded when ab.c is compiled by the same toolchain as libcrypto.dll, isn't available in non-openssl distributions, and was deprecated in 1.1.1 again.

Anyone interested can proceed to patch both and provision applink.c when working with OpenSSL 1.1.1, so I don't need to raise a ticket at that project.

No problem to patch.

Rather than ApacheLounge and some others needing to patch each time, 
did we conclude that we should wire in the applink.c stub into Apache.exe
as shipped by httpd project?

(I've never mixed binaries of different MSVC environments, so myself,
I don't care, but it seems to raise issues for a subset of the community.)

This is why the patch creator put this inside a HAVE_OPENSSL block so
ab.exe did not get this added. abs (at least on the dsp et. al.) is not
built unless there is OpenSSL present.

Seems to me this is not needed .

So, is the win32 community in favor of using HAVE_OPENSSL to include applink.c in the scope of main.c (as revised in the current ab.c sources, to avoid this on libressl?)

There is a presumption that the crt used by libhttpd the same as libapr, but I think this is a reasonable connection.

The entire logic to main.c should be as simple as...

#if defined(HAVE_OPENSSL) && defined(_MSC_VER) && !defined(LIBRESSL_VERSION_NUMBER)
/* The following logic ensures we correctly glue FILE* within one CRT used
 * by the OpenSSL library build to another CRT used by the ab.exe build.
 * This became especially problematic with Visual Studio 2015.
#include <openssl/applink.c>

By inserting the structure in httpd.exe, that structure can be found by the openssl library, which is not true of including this in a loadable library such as libhttpd.dll or libaprutil-1.dll.
