Bug 198317 – WKWebsiteDataStore API fails to fetch web storage data for non-persistent data store

• Component: New Bugs
• Status: RESOLVED FIXED

[Sihui Liu]

In non-persistent session, we used SessionStorageNameSpace for localStorage and used in-memory map for sessionStorage. This is confusing, and makes it hard to maintain the same behavior for persistent session and non-persistent session.

R=me with a few comments, mostly stylistic.

> Source/WebKit/NetworkProcess/WebStorage/StorageManager.cpp:94
> +    Ref<StorageArea> getOrCreateStorageArea(SecurityOriginData&&, bool);

bool isEphemeral
Or
enum class IsEphemeral : bool { No, Yes }

> Source/WebKit/WebProcess/WebStorage/StorageAreaMap.cpp:388
> +    default:

Let's remove this default.

> Source/WebKit/WebProcess/WebStorage/StorageNamespaceImpl.cpp:50
> +    return createLocalStorageNamespace(identifier, quotaInBytes, true);

Let's give this "true" a name.
Either use enum class IsEphemeral : bool { No, Yes } or bool isEphemeral = true;

> Source/WebKit/WebProcess/WebStorage/StorageNamespaceImpl.h:44
> -    static Ref<StorageNamespaceImpl> createLocalStorageNamespace(uint64_t identifier, unsigned quotaInBytes);
> +    static Ref<StorageNamespaceImpl> createLocalStorageNamespace(uint64_t identifier, unsigned quotaInBytes, bool isEphemeral = false);

I think with something like this we shouldn't have a default parameter so we don't forget to state whether it's ephemeral or not.

It appears that the changes in https://trac.webkit.org/changeset/245881/webkit

Oops, this should be NO. 

Tested the fix on local build.

This change appears to have caused the following API test failure:

I cannot reproduce the test failure, but I do get flaky timeout on this test when running multiple times. I will fix the test first in https://bugs.webkit.org/show_bug.cgi?id=198450.

As the failure didn't reveal too much information, I also changed to use EXPECT_WK_STREQ instead of EXPECT_TRUE in the fix above.

It appears after patch re landed as r246079 the same API test is failing flakily on Release bots. 

I am trying to reproduce it locally and so far I cannot. Trying on a few other machines and will post repro steps if possible. Appears to be a different failure message than previously.

I cannot reproduce the failure either. If you find the failure shows up on some bot very frequently, probably we want to debug on that bot?

Was able to reproduce with a release build.
