Bug 169275 – watchlists seem to be failing sometimes

• Status: RESOLVED
• Resolution: CONFIGURATION CHANGED
• Component: Tools / Tests

[Manuel Rego Casasnovas]

At least I'm finding issues with the CSS Grid Layout watchlist.

The watchlist is defined like:
        "CSSGridLayout": {
            "filename": r"Source/WebCore/rendering/.*Grid.*"
                        r"|Source/WebCore/css/.*Grid.*"
                        r"|LayoutTests/fast/css-grid-layout/"
                        r"|LayoutTests/ietestcenter/css3/grid/"
                        r"|LayoutTests/platform/.*/fast/css-grid-layout/"
                        r"|LayoutTests/platform/.*/ietestcenter/css3/grid/",
        },

And the people subscribed are @jfernandez, @svillar and me.

But in the last weeks we were not CC in some patches:
* https://bugs.webkit.org/show_bug.cgi?id=168657
* https://bugs.webkit.org/show_bug.cgi?id=169203

But I did a small test and it worked:
* https://bugs.webkit.org/show_bug.cgi?id=169073

So I'm not sure what's going on, but it'd be really nice to get this fixed.
Thanks!

I never looked into how the watchlist works. Is it part of style queue on EWS?

[Lucas Forschler]

the style queue runs the watch list. It is throwing errors in the logs:


style-queue_2018-12-05_07-12.log:2018-12-05 07:48:04,975 - Failed to run "['/Volumes/Data/StyleQueue/WebKit/Tools/Scripts/webkit-patch', '--status-host=webkit-queues.webkit.org', '--bot-id=webkit-misc-style', 'apply-watchlist-local', 190625]" exit_code: 1 cwd: /Volumes/Data/StyleQueue/WebKit

I looked through this a bit more, and it seems the most current errors being thrown are cases where the bugs are security bugs, and the EWS account does not have access. This is by expected. We do not want the watchlist to elevate access for security bugs.

However, the ones from Manuel are NOT security bugs. I don't have logs from that far back to investigate.

webkit-patch apply-watchlist-local bug_id -v

[Lucas Forschler]

running the above command would give some insight to why it's not working. If you could follow up with log output from running, we can diagnose more.

Watchlist was definitely having issues with Security bugs. It has been fixed in https://bugs.webkit.org/show_bug.cgi?id=190793
