#1758: Open ended range request results in truncated images
-----------------------------+--------------------
Reporter: jafa | Type: defect
Status: new | Priority: normal
Milestone: | Component: build
Version: 4.0.3 | Severity: normal
Keywords: range truncated |
-----------------------------+--------------------
Symptom: client (Kodi) getting truncated images.

Client (Kodi) sent requests HEAD, HEAD, GET. The GET request include
"Range: bytes=0-".

Varnish responded:
HEAD: "Content-Length: 50726"
HEAD: "Content-Length: 50726"
GET: "Content-Range: bytes 0-14157/14158" and "Content-Length: 14158"

A few minutes later I hit it from a webbrowser (no range request).
Varnish responded with "Content-Length: 50726" and delivered the complete
data.

Full headers in attached files.

Workaround = "unset req.http.Range". This avoids the problem - images are
delivered correctly.

Comment (by lkarsten):

This should be fixed in git master. Please try that.

We need to look if this should be ported back to 4.0.

Thanks!

Backporting... we can live with the "unset Range" workaround until 4.1 is
released if needed however given that it is a data corruption bug it might
make sense to backport for everyone.

If the decision is made to backport to 4.0.x I am happy to test in a live
environment.

To sum up: you can't test the fix, but if we backport you can test the new
code.

Keeping this ticket open until we have a chance to look at amount of work
to backport.

Hi.

This should be fixed in the 4.1.1. No backport necessary.
