1745063 - Assertion failure: gIOService->IsNetTearingDown(), at /builds/worker/checkouts/gecko/netwerk/base/nsSocketTransportService2.cpp:1855

Status: RESOLVED FIXED

(Core :: Networking, defect, P2)

Description

[Kershaw Chang [:kershaw]]

Hit this assertion when trying to enable running xpcshell tests on windows with socket process.

Here is the explanation:

1. Shutdown begins. We first send SetOffline and second "profile-change-net-teardown" notification to socket process.
2. In socket process, nsIOService::SetHttpHandlerAlreadyShutingDow is called by nsHttphandler here.
3. At this point, gIOService->IsNetTearingDown() is true, because mHttpHandlerAlreadyShutingDown is true.
4. Now, nsIOService::Observe is called with "profile-change-net-teardown".
5. mHttpHandlerAlreadyShutingDown is reset to false here and mOfflineForProfileChange won't be set to true because SetOffline is happened before.
6. gIOService->IsNetTearingDown() becomes false and we hit the assertion.
