Complete the separation of synthetic from received objects. · 3e610dc8

Poul-Henning Kamp authored Jul 31, 2008

	Any object, also errors, we receive from the backend will
	go to vcl_fetch(), and can be cached if desired.

	Any object we create, for instance if we cannot contact the
	backend, will go to vcl_error() and will not be cached.

Technical details:

	Implement VCL variable setting for booleans like obj.cacheable.

	Remove obj.valid, only valid objects go to vcl_fetch now.

	On fetch failure, drop the object and go to STP_ERROR with 503

	Update testcase b00015.vtc accordingly.

NB: Be careful with -trunk, this is a quite intrusive change.

Continue the progress on synthetic/error pages

The default "guru meditation" is now generated from the vcl_error {}
function, which can be redefined to whatever suits your taste.

Techinical:

Add new vcl_error method and make variables available in it.

Fix a bug in "error" action, where the numeric argument would not get
interpreted correctly if it came from a variable like obj.status.

Forbid "error" action in vcl_deliver since vcl_error now goes to
vcl_deliver to send the error object.

Fix test v00001 to reflect this.

Move the obj->ws/http initialization to preallocation time to avoid
duplication.

Add read-only variable req.xid (a string!)

Add default guru meditation to default vcl.

Remove cache_synthetic.c which is now unecessary.

Add a facility to constructing a synthetic object from VCL. · 8c5b78ff

Poul-Henning Kamp authored Jul 25, 2008

This is just the initial version and it doesn't quite work the way
we need it to yet, but the idea is to be able to say:

	sub vcl_fetch {
	    if (obj.status == 503) {
		synthetic {"
		    <HTML>
		    <H1>Sorry, could not contact the backend server</H1>
		    <P>
			Try again later.
		    </P>
		    <HR>
		    <PRE>
			URL: "}  req.url {"
			User Agnet: "} req.http.user-agent {"
		    </PRE>
		    </HTML>
		"};
	    }
	}

A new VCL syntactic element have been introduced to do this: "the
long string".   A long string is anything from {" to "}, newlines,
controlcharacters and all.  (Normal "..." strings cannot contain
control characters.

Technical details:

Don't NULL terminate string sequences in VRT context, we may have
NULL cropping up as a legal value if a header is missing, add the
magic "vrt_magic_string_end" for terminating string contactenation.

Add an explicit clock-skew window (parameter: clock_skew) and only

this window.

is before the Date:, even if the Date: is out side our window.
