created issue #1

Feb 27, 2025 05:21PM

On tip of trunk, build and run ChromeOS (running on Linux).
(@koulvipul, apologies if you're not the right person to assign to. I saw that there were crashes like this before:

bug 324671489

and

bug 40896374

, and that you fixed the most recent one.)

I get this crash at startup every time. I've tried running with and without --user-data-dir, with an empty value for it, or with a directory.

Status: Won't Fix (Infeasible)

It's working now. The issue was that another instance was running at the same time.

Vipul, I think the line referring to multidevice_setup_client_factory.cc isn't part of the stack trace.

I'm not sure why this crashes though.

Aaron, perhaps the build is corrupted? Could you try a fresh build?

ba...@google.com <ba...@google.com> #5Feb 27, 2025 10:30PM

I think that the problem is that in this line https://source.chromium.org/chromium/chromium/src/+/main:components/autofill/core/browser/webdata/payments/payments_autofill_table.cc;l=488;drc=9c6a9a1fff68e133a2329104c77d77858f75c6b3 the db is a nullptr.

This happens if the database cannot be opened or has been closed.

Based on these lines

#11 0x55a27737858a 2025-02-27T17:09:12.973887Z ERROR chrome[345412:345538]: [default_socket.cc(60)] /run/perfetto/ exists but cannot be accessed. Falling back on /tmp/  (errno: 13, Permission denied)

I could imagine that you have some kind of permission problem with your home directory.

My hunch would be that if you add a LOG(ERROR) to the two db_.reset(); lines in https://source.chromium.org/chromium/chromium/src/+/main:components/webdata/common/web_database_backend.cc, one of the twou would trigger and point you closer to the source of proboems..

As Araon specify, Chrome can't have multiple instances running at the same time and opening the same database.
These database are locked.

What is puzzling me is that we do have code for the process singleton that ensures only one instance of Chrome is running per user-data-dir. How did you manage to have two instances?

al...@chromium.org <al...@chromium.org> #7Feb 28, 2025 02:09PM

Etienne, it probably relates to me running the chromeos version of Chrome. I'm building and running on Linux, not through an emulator, using target_os = "chromeos".
