Just a heads up that Chrome 72 no longer allows null characters in response headers.  We'll see if that change sticks.  Any reports of getting ERR_INVALID_HTTP_RESPONSE in 72 are most likely due to this change.

Oh, also, the FindIt bots have been filing a bunch of redundant bugs about the tryserver failing to start.  If you see a bug filed by FindIt, and the linked test logs have a dozen failing OCSP, FTP, WebSocket, and random SSL tests failing, then you can dupe it against issue 869227

Pretty slow shift - re-triaged a network crasher that might actually be a security issue (If a rather difficult to exploit one that already requires local network access, I believe), and an OAuth2 issue that I don't really know enough about OAuth2 to make progress on.

The auto-untriage from bugs not modified in a year continues.  We went through quite the triage backlog about a year ago, so all the lower priority ones are coming up again now.

Found a couple non-emergency but actionable issues that had slipped through the cracks and ignored for a couple weeks.  Think I got them all resolved.

Triaged up to 989338, there is an interesting bug report(crbug.com/986949) from Amazon which indicates that Chrome doesn't fall back to the default system resolver when hitting failures with AsyncDNS flag is on.

Triaged up to 990077.

Poked a bit at the AsyncDNS report from Amazon that Cherie mentioned, which seems to be an issue with what platform APIs are telling us.  Only other interesting bug was https://crbug.com/990041 - turns out WebRequest APIs have to use a magic way to set headers now, to work with OOR-CORS.

Otherwise, a pretty slow shift.  Poked unsuccessfully at a crasher or two, and removed a bit of code that's now unused as a result of the NetworkService being enabled by default in Chrome, though still a lot of code we need to keep around until it's the default on all supported embedders.

Multiple bug reports of canary not loading any pages and using 100% cpu, due to crbug.com/994537. That bug also manifested as a spike in renderer hangs since the network service would not respond to cookie requests from the renderer, which were attributed to crbug.com/987475.

No new crashers.

Spent some time fixing a flaky crashing test crbug.com/979258.

Forgot to mention another notable bug, if you see reports about HTTP auth dialog disappearing immediately and a different page loading (for example when trying to login to netgear router admin page), it's probably a dupe of https://crbug.com/992639 (the causing feature was reverted, but still affecting current dev and beta versions).

Did we change how the rotation works? Based on the existing pattern, I think my shift should end today, but rota-ng says it lasts until tomorrow at 9pm. Is that correct, or did the start/end times on rota-ng get messed up?

Also, the next slot is currently empty. I'll be out on Friday so won't be able to take it. Would someone else be able to take Thursday/Friday?

The shift spans two calendar dates during your normal working hours. There is an internal thread discussing this.
(The TL;DR is that rota-ng currently uses midnight EST which wraps poorly for pacific time. Will change to 00:00 PDT for the next rotation).


Also, the next slot is currently empty. I'll be out on Friday so won't be able to take it. Would someone else be able to take Thursday/Friday?

I will take care of thu/friday's activity during my shift next week.
The originally scheduled person dropped out and I wasn't able to get a replacement.

No worries, Matt. I tried to make sure to go through the old ones. Triaged up to 1002622

This seemed to be a ChromeOS heavy shift - https://bugs.chromium.org/p/chromium/issues/detail?id=1002585 https://bugs.chromium.org/p/chromium/issues/detail?id=1002010 https://bugs.chromium.org/p/chromium/issues/detail?id=1001797 and https://bugs.chromium.org/p/chromium/issues/detail?id=1001886 . My understanding is NetLogs don't help here, so hoping the ChromeOS Networking Team can gather the data they need here. https://bugs.chromium.org/p/chromium/issues/detail?id=1000696 was also slightly interesting.

I saw a little interested related to https://crbug.com/982341 , which removed the "Always open" option from the prompt. https://textslashplain.com/2019/08/29/web-to-app-communication-app-protocols/ is a good write-up of why, from someone on the Edge team at Microsoft.

Nothing terribly exciting, but there were a few crashers I found.

Most issues I investigated during my shift were external issues or working as intended.

The most interesting issue was crbug.com/1011685, which notes that IP based H2 session resuse on Canary is not happening as expected for a news site. This looks legitimate, and there have been a few changes that could affect this. Pooling is now more dependent on sequencing of DNS resolutions, and pooling can also be reduced by NetworkIsolationKey enforcement.

Misc:
 * Two reports related to bad self-signed certs being used in localhost development
 * One report related to misconfigured MiTM proxy (enterprise policy required hard-fail revocation checking, however it did not provide any revocation methods)
 * A few FTP bug reports, due to deprecated functionality (embedded resources from ftp:// not allowed, and proxy support for FTP was removed)
 * A report of requests hanging for multiples of 45 seconds. Evidence is pointing towards a problem with F5 middlebox breaking re-used HTTP 1.1. sockets to the endpoint, causing us to hit the TCP keep alive timeout.
 * Some website gives 403, looks to be a serverside problem.
 * Some website closing connection without a response, looks to be a developer's serverside problem as the reset was initiated by the server.
 * Some proxy not supporting H2, so requests go over HTTP 1.1 and are affected by connection limits. Looks to be the proxy developer's server side problem, which is likely exacerbated by weird stuff that docs.google.com does (and possibly serving different content when loaded over H2?)

Triaged to 1022691.

Spent most of time on a QUIC related crash, crbug.com/1014092 and crbug.com/1011923, hopefully it's fixed now.

There are quite a few fuzzer related bugs indicating fuzzer is timing out, however, there is not much useful information where the timeout is from. It is said reproducible, I'll try it tomorrow to see if I can get a repro. 

Didn't get much time to follow up Needs-Feedback components.

The way I recommend investigating fuzzer timeouts is to download the test case file from cluster fuzz, and then run it against the fuzzer using the "perf" profiler (https://chromium.googlesource.com/chromium/src/+/master/docs/linux_profiling.md).

The callstack sampling is usually clear on where the time was being spent.

That said, in the most of the cases we have seen, timeouts are due to extraordinary inputs generated by the fuzzer which do not warrant changes to the implementation. For instance many timeouts have been due to expanding crazy big URLs, or URLs with lots of funky IDNA weirdness that waste time in ICU. In these cases the fix is to just adjust the fuzzer itself to avoid generating these expensive cases. This can be done by changing the C++ fuzzer, or the fuzzer driver (modify net/BUILD and add a "libfuzzer_options" to limit the overall data size).

Triaged up to 1024536.  Pretty uneventful shift:  No new crashes.  Fixed a fuzzer that was timing out.  There's another more complicated one that I didn't get to.

cc rotation owners between Dec 14 and Dec 29, holiday rotations excluded. 

There has been no bug triage report since 12/13. Currently there are 16 unconfirmed issues and 23 needs-feedback followup issues on the dashboard, which is a ton to catch up. 

Given many folks are taking vacations near the holiday season, I wonder if it's MIA or just missing reports. Does anyone know where I should start triaging?
