We have https://ci.chromium.org/buildbot/chromium.clang/ToTLinuxUBSanVptr/ which builds and runs tests using tip-of-tree clang.


I guess we want to keep "UBSanVptr Linux" too. I'm not sure chromium.clang is the best place for it though. It was probably on chromium.fyi before since it was a somewhat experimental config. It doesn't look like we have that config running anywhere else.

Maybe we should just give "UBSanVptr Linux" the same test list as ToTLinuxUBSanVptr. My question is who is supposed to keep an eye on it..

krasin used to look at that bot. Is there a new krasin? Not really, right?

Note, it looks like the "UBSanVptr Linux" bot was moved from chromium.fyi to chromium.clang in https://chromium-review.googlesource.com/702016 .

We can easily restore the tests that used to run on it by undoing a portion of https://chromium-review.googlesource.com/927882 . Would you like me to do that?

> krasin used to look at that bot. Is there a new krasin? Not really, right?

No really :(

kbr: Yes please, let's reinstate the tests.

The question of who is supposed to monitor that bot is a different question. In practice, the clang sheriffs are looking at the ToT version anyway.

No problem, I'll put the tests back on this bot. https://chromium-review.googlesource.com/933862 up for review.

Reinstate tests on "chromium.clang:UBSanVptr Linux".

Put most of the changes back from
https://chromium-review.googlesource.com/927882 , but moved the bot
from chromium.fyi to chromium.clang.

Reinstated the old exceptions, but left the bot Swarmed, as there
seemed to be no good reason why it wasn't previously Swarmed.

Tweak which tests run on ToTLinuxUBSanVptr and UBSanVptr Linux.

https://chromium-review.googlesource.com/c/chromium/src/+/933862 added
chromium_linux_clang_and_gl_gtests to the UBSanVptr Linux bot, while
the ToT bot only runs chromium_linux_clang_gtests -- and gl_unittests
doesn't run under ubsan yet (see blockers of crbug.com/815183). So
switch UBSanVptr Linux to chromium_linux_clang_gtests instead.

Many of the tests that were run on UBSanVptr Linux do pass, so run
those on ToTLinuxUBSanVptr too. Namely, aura_unittests, capture_unittests,
chromedriver_unittests, components_browsertests, compositor_unittests,
dbus_unittests, events_unittests, gin_unittests, media_unittests,
mojo_common_unittests, mojo_unittests, nacl_loader_unittests,
ui_touch_selection_unittests, and wm_unittests now run on the ToT bot.

Generally check that if a test is disabled on ToTLinuxUBSanVptr
it's disabled for UBSanVptr Linux too (notably, interactive_ui_tests
no longer runs on the non-tot bot, which also doesn't pass. But
services_unittests now does run, like on the tot bot).
