Bug 284507 – REGRESSION (282256@main): [ macOS wk1 ] storage/indexeddb/objectstore-basics.html is a flaky timeout/crash

• Status: RESOLVED
• Resolution: FIXED
• Component: Website Storage

[Karl Rackler]

Description:
storage/indexeddb/objectstore-basics.html

The test crashes on macOS debug wk1 and times out on macOS release.

I could not bisect to a commit due to the lack of spades in that range; I cannot pinpoint what change could have caused this. 
Debug
282254@main --> Passed
282292@main --> Crashed

The commit range is https://commits.webkit.org/compare/282292@main...282254@main.  I reviewed the changes, and 282256@main seems most likely due to its changes involving an idbobjectstore test with indexeddb/client.

This issue can be reproduced using the command:
run-webkit-tests --debug -1 --debug-rwt-logging --iterations 1 --force --no-retry --child-processes 1 --test-list test-list-objectstore-basics.txt

History:
https://results.webkit.org/?suite=layout-tests&test=storage%2Findexeddb%2Fobjectstore-basics.html&flavor=wk1

Crash Log:
No crash log found.

stdout:

stderr:
ASSERTION FAILED: isMainThread()
/System/Volumes/Data/otmp/case-sensitive/od.luxon/lw.luxon/sandbox-0/workspace/OpenSource/Source/WebCore/Modules/indexeddb/client/TransactionOperation.h(72) : void WebCore::IDBClient::TransactionOperation::transitionToComplete(const IDBResultData &, RefPtr<TransactionOperation> &&)

No diff for timeout.
