hash_md5 failing

[huguesalary]

Hi there,

I just compiled your vmod on my Mac Os X 10.6.8

$varnishd -V
varnishd (varnish-3.0.2 revision 55e70a4)
Copyright (c) 2006 Verdens Gang AS
Copyright (c) 2006-2011 Varnish Software AS

I tried using the digest.hash_md5() function in my VCL, the VCL compiles with no error, but when I make an HTTP request, nothing is returned to the browser.

I then tried using digest.hash_sha1, and it works.

VCL Config

import digest;

sub vcl_deliver
{
    set resp.http.whatever = digest.hash_md5("test");
}

Am I missing something?

Could you try to run 'make check' ?

[huguesalary]

The make check fails for me, but it actually fails for every single vmod I compile. I suspect a problem with varnishadm on the mac os x port. If I read the test well, it seems to fail because varnishadm is supposedly not answering. But we clearly see later that it does. Something that also makes me think there's a problem with varnishadm is that when I start it and use it, there's no prompt. Typing a command and validating with [enter] will execute the command normally though. I added a picture, that should help.

$make check

varnishadm

[lkarsten]

Hi.

From what I see it appears that libmhash has a problem on BSD and macos. The rest works. The libvmod-digest layer between Varnish and libmhash is pretty thin.

The varnishadm problem you describe is probably readline/editline related and shouldn't influence this vmod in any way.

Are you still experiencing this? What libmhash version are you running?

[huguesalary]

Hi Lasse,

I haven't tried on the latest version of Varnish. As soon as I can I'll compile the latest version and try again.
