Bug 28262 – SecurityOrigin::createFromDatabaseIdentifier contains bugs

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Steve Block]

SecurityOrigin::createFromDatabaseIdentifier contains the following two bugs.

Line 286
When testing that the identifier contains at least two separators, the test is reversed. As a result, identifiers with at least two separators are erroneously rejected.
This was introduced in http://trac.webkit.org/changeset/44423.

Test case ...
INPUT:    "http_webkit.org_80"
ACTUAL:   SecurityOrigin(KURL()) (input rejected)
EXPECTED: SecurityOrigin(KURL("http://webkit.org:80"))

Line 292
When testing that the port is either a valid integer or absent, the logic is incorrect. Instead, the logic tests that the port is a valid integer or present. Hence identifiers where the port is absent are erroneously rejected and those where the port is present but invalid are erroneously accepted.
This was introduced in http://trac.webkit.org/changeset/29386.

Test cases ...
INPUT:    "http_webkit.org_"
ACTUAL:   SecurityOrigin(KURL()) (input rejected)
EXPECTED: SecurityOrigin(KURL("http://webkit.org:0"))

INPUT:    "http_webkit.org_string"
ACTUAL:   SecurityOrigin(KURL("http://webkit.org:0"))
EXPECTED: SecurityOrigin(KURL()) (input rejected)

I'll take a look.

Is there a way to add low-level tests for this kind of functionality?

Not really.  And, in fact, I created a bug suggesting that we do find a way.  This class seems trivial to unittests, but ther'es no framework at the moment.  (Only LayoutTests.)

The best way to make tests for this is to figure out what actual effect the bugs would have. It's OK to have them not tested if there's no obvious way to do so. Building a lower level unit test machinery would allow testing things like this, but would have other costs that may not be acceptable.

Find to just land this as-is. r=me

Assigning to benm for landing.
