[GitHub] [trafficserver] shinrich opened a new pull request #6809: Fix assert when client aborts during backfill
shinrich opened a new pull request #6809:
URL: https://github.com/apache/trafficserver/pull/6809
@randall noticed this assert when exercising PR #6686 but the issue seemed to be independent of the PR, so I separated the fixes into a separate PR.

+1 to this patch. The change looks good to me and I've been running this patch in our prod 9.0.x and don't see any issues specifically with it (there are still some other unrelated crashes that I'm looking into in 9.0.x but this patch on its own looks good).

This is running ATS 9.0.x plus the hostdb fixes?
randall 5:53 PM
yes, and now “Remove remnants of http/1.1 pipeline logic” (I forgot to revert before running this test)
Susan Hinrichs 6:00 PM
Hmm. My line numbers aren't matching yours. Did you start with ATS/9. 0 and cherry pick in the others?
6:01
Or can you just push your branch?
randall 6:03 PM
I started with 9.x and cherry-picked and then hand applied your last change (too lazy to undo and redo).
6:04
let me clear and re-run
6:04
I also added a warn to verify I actually tried your code (just to make sure I wasn’t losing it)
6:05
and l’ll try with the official upstream 9.0.x (I think we have no cherrypicks so far, but better safe here)
