Bug 65997 – [Chromium] Decouple implementation of allowFileSystem, openFileSystem and allowDatabase from WebWorkerBase

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Dmitry Lomov]

After dedicated workers move in-process, they will no longer be using WebWorkerBase as a base implementation class.

Implementation

This patch moves implementation of allowFileSystem, openFileSystem and allowDatabase from WebWorkerBase to respectively LocalFileSystemChromium and DatabaseObserver, parametrizing them with relevant data from WebWorker.

(chromium trybots are happy)

Please add an empty line after the link.

> Source/WebKit/chromium/ChangeLog:9
> +        * src/DatabaseObserver.cpp:

Please add more detail regarding this particular file here. For example, you can add:
  Move allowDatabase from WebWorkerBase and update the caller.

> Source/WebKit/chromium/src/DatabaseObserver.cpp:90
> +                                                                createCallbackTask(&didComplete, WebCore::AllowCrossThreadAccess(this), result), m_mode);

You can join this line and the line above it.

> Source/WebKit/chromium/src/DatabaseObserver.cpp:107
> +        if (!commonClient)

You can flip the if condition and swap the two actions.

> Source/WebKit/chromium/src/DatabaseObserver.cpp:124
> +bool allowDatabaseForWorker(WebCommonWorkerClient* commonClient, WebFrame* frame, const WebString& name, const WebString& displayName, unsigned long estimatedSize)

I think allowDatabaseOnWorker sounds better.

> Source/WebKit/chromium/src/DatabaseObserver.cpp:130
> +    WebCore::WorkerLoaderProxy* workerLoaderProxy =  &workerContext->thread()->workerLoaderProxy();

You can replace "workerContext->thread()" with workerThread.

> Source/WebKit/chromium/src/LocalFileSystemChromium.cpp:145
> +    WebCore::WorkerLoaderProxy* workerLoaderProxy =  &workerContext->thread()->workerLoaderProxy();

ditto.

Also, can you use a helper function to get workerThread?

> Source/WebKit/chromium/src/LocalFileSystemChromium.cpp:168
> +    WebCore::WorkerLoaderProxy* workerLoaderProxy =  &workerContext->thread()->workerLoaderProxy();

ditto.

> Source/WebKit/chromium/src/WebWorkerBase.cpp:53
> +#include "WorkerLoaderProxy.h"

It seems that you can also remove the including of WorkerFileSystemCallbacksBridge.h, WorkerScriptController.h and others.

> Source/WebKit/chromium/src/WebWorkerBase.h:95
> +    WebView* webView() { return m_webView; }

Please add const modifier.

> Source/WebKit/chromium/src/WebWorkerBase.h:97
> +    virtual WebCommonWorkerClient* commonClient() = 0;

Please add empty line after this.

> Source/WebKit/chromium/src/WorkerFileSystemCallbacksBridge.h:42
> +#include "WorkerLoaderProxy.h"

You can use forward declaration for WorkerLoaderProxy, instead of including it.

Do not forget to remove the forward declaration for WebWorkerBase.

Changed formatting to make code clearer.

Done although this was the orinal code.

>> +bool allowDatabaseForWorker(WebCommonWorkerClient* commonClient, WebFrame* frame, const WebString& name, const WebString& displayName, unsigned long estimatedSize)

Why for? We are allowing database _for_ worker. Also consistent with other naming (openFileSystemForWorker)

>> +    WebCore::WorkerLoaderProxy* workerLoaderProxy =  &workerContext->thread()->workerLoaderProxy();

Done.

I need both workerThread and workerContext out of this 3 lines of code, so I do not feel separate function is very useful.

>> Source/WebKit/chromium/src/LocalFileSystemChromium.cpp:168
>> +    WebCore::WorkerLoaderProxy* workerLoaderProxy =  &workerContext->thread()->workerLoaderProxy();

Done.

Almost there. Just some more minor comments.

> Source/WebKit/chromium/ChangeLog:8

typo: parameterizing

> Source/WebKit/chromium/ChangeLog:10
> +        * src/DatabaseObserver.cpp:Move allowDatabase from WebWorkerBase and update the caller.

Please add a whitespace after ':'.

> Source/WebKit/chromium/ChangeLog:20
> +        * src/LocalFileSystemChromium.cpp:Move allowFileSystem and openFileSystem from WebWorkerBase and update the caller.

ditto.

> Source/WebKit/chromium/ChangeLog:30
> +        * src/WorkerFileSystemCallbacksBridge.h:

Please also add more comment here, like:
  Change WorkerFileSystemCallbacksBridge constructor to take WorkerLoaderProxy argument.

> Source/WebKit/chromium/src/LocalFileSystemChromium.cpp:122
> +        if (!commonClient)

Since you're already in this code, why not just making it better?

> Source/WebKit/chromium/src/LocalFileSystemChromium.cpp:184
> +

Please remove an extra blank line.
