It looks like the hello world source set doesn't include opt.c. I don't
have access to any Windows machines to confirm though.

I got it compiled by including opt.c in the visual studio project, however when I run the program and fire off a request, it immediately exits. See the attached gif.

[nmdguerreiro]

If you compile in debug mode, do you get an error message when you run it?

[mikeptweet]

Nope ... nothing. The same thing happens if I try to connect via the
browser. The server ends immediately.

I wonder what
https://github.com/kellabyte/Haywire/blob/master/src/haywire/http_server.c#L203
is
actually returning in that case. Could you print the result of that call?

I set up the debugger in Visual Studio and it breaks here (strlen.asm)

Here is where the error occurs ... getting the strlen(current_time)

Sorry ... here's the screenshot

[nmdguerreiro]

Humm, that's weird. I just checked the documentation on MSDN and ctime is supposed to return a null terminated string, so strlen shouldn't have an issue.

Note that current_datetime.length is initialized until the next line runs. Does strlen cause a segmentation fault or does it return?

[mikeptweet]

It causes a segmentation fault and the program exits

And what's the value of current_time btw? I wonder if that is returning NULL.

If you need a Windows Environment to test on ... just load up this Hands On Lab from Microsoft and it gives you a full blown remote Windows - Visual Studio 2015 environment all avilable from a web browser

[nmdguerreiro]

Sweet!

[nmdguerreiro]

@mikeptweet - I ran build.bat to generate the solution files and I didn't have to add any additional sources. After that I was able to reproduce the error. I fixed it by adding:

#include <time.h>

at the top of http_response_cache.c.

Can you try doing that and running again just to confirm?

[nmdguerreiro]

Opened #77 to fix it. Without the header, the current time is returns as negative and that causes ctime to return an invalid string.

[mikeptweet]

Bingo ... thanks a bunch :-)

[nmdguerreiro]

Happy to help :-)
