investigate flaky test-domain-error-types in CI #30498
Comments
This is happening a lot. I'm not sure it's necessary to paste more of these in here at this point, but here's one more.

today seen again:

Backtrace with optimized V8 debug:
I’ll try to get one from a non-optimized build but this is most likely a V8 GC bug. @nodejs/v8 |
Full stack trace:

I’m not really sure how to debug this correctly … valgrind is impractical here, I can’t run the test file in debug mode under it in less than three hours and even then I’d assume the test would still be flaky. If the @nodejs/v8 team has any guidance/ideas for next steps, I’m all ears :) |
This looks a lot like node/deps/v8/src/common/globals.h Line 529 in eb30b2c
|
Do we think we're likely to have something we can do here soon-ish or should we mark the test as flaky (or, probably better, skip on the one platform where there's a problem, if possible)? |
Skip it for now on the one CI configuration where it fails frequently? #30629 |
Until nodejs#30498 is resolved, skip test-domain-error-types on debug builds. PR-URL: nodejs#30629 Reviewed-By: Richard Lau <[email protected]> Reviewed-By: Anna Henningsen <[email protected]>
Original commit message: [heap] Ensure SyntheticModule is initialized before next allocation Ensure that all fields of `SyntheticModule` are set before creating the exports hash table for it, because the latter may trigger garbage collection, leading to crashes. This has been causing failures in the Node.js CI over the last weeks, after making the creating of synthetic modules part of Node’s startup sequence. (I am generally not very familiar with this part of the V8 code and there might be a better way, or possibly a way to add a reliable regression test, that I am not aware of.)

Not sure who is in a position to dig in to figure this out so I might be pinging a bit more widely than some people may prefer, so apologies in advance if so. Pings: @nodejs/build @nodejs/testing @nodejs/domains @nodejs/docker @nodejs/diagnostics
