1322514 - PermissionKey CTOR should not crash

Status: RESOLVED FIXED

(Core :: DOM: Core & HTML, defect)

Description

[Andrea Marchesini [:baku]]

Attachment: crash_blobUrl.patch

Debugging something completely unrelated, I found this crash:

[Child 26769] WARNING: NS_ENSURE_TRUE(standardURL) failed: file /home/baku/Sources/m/foobar/src/caps/nsPrincipal.cpp, line 173
[Child 26769] WARNING: NS_ENSURE_SUCCESS(rv, rv) failed with result 0x80004005: file /home/baku/Sources/m/foobar/src/extensions/cookie/nsPermissionManager.cpp, line 108
Assertion failure: false (NS_SUCCEEDED(GetOriginFromPrincipal(aPrincipal, mOrigin))), at /home/baku/Sources/m/foobar/src/extensions/cookie/nsPermissionManager.cpp:609

I was able to reproduce twice, but now I cannot. This is why a test is not attached.
Btw, GetOriginFromPrincipal can fail. We should change how we create PermissionKey objects.
I'll do that in a follow up.

Please add a comment about why we're doing this.

nsIPrincipal::GetOrigin should use the parent principal when dealing with blobURL, r=ehsan
