Bug 71968 – Implement URL API

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: DOM

[Erik Arvidsson]

http://dvcs.w3.org/hg/url/raw-file/tip/Overview.html

[Erik Arvidsson]

There is currently a webkitURL which is implemented as DOMURL. It has 2 static methods

createObjectURL
revokeObjectURL

Gecko also implements these 2 but they do not use a prefix.

I'm suggesting we start adding features from the URL API draft to DOMURL but we keep the 2 static methods.

[Kaustubh Atrawalkar]

I wish to implement this. Should I provide the working progress patch ?

That sounds reasonable.

The spec is pretty much work in progress so expect things to change. For example, it is a known spec bug that the spec uses a DOMTokenList

Yes, thats right. Is it fine to add different patches for the progress?

IDL Attributes implementation

This is initial patch implementing IDL attributes. IDL functions are still empty and in queue for implementation as there is blocking bug for not having DOMTokenList in DOMURL object.
I would like to rename this bug to "Implementing DOMURL IDL Attributes" and make a meta bug to track other function implementation bug in a master bug "[Meta] DOMURL Implementation".
Let me know your views on this.

Dunno.  You can build and test Chromium by adding --chromium to update-webkit, build-webkit, and run-webkit-tests.

Can you add tests that ensures that:

webkitURL instancof Function

new webkitURL(...) instanceof webkitURL

webkitURL.createObjectURL instanceof function

new webkitURL(...).createObjectURL === undefined
new webkitURL(...).revokeObjectURL === undefined

webkitURL.prototype.getParameter instanceof Function
new webkitURL(...).hasOwnProperty('getParameter') === false

etc

> Source/WebCore/html/DOMURL.idl:30
>          Conditional=BLOB,

The conditional should be moved to createObjectURL and revokeObjectURL

> Source/WebCore/html/DOMURL.idl:56
>          [ConvertNullStringTo=Undefined] DOMString createObjectURL(in MediaStream stream);

This and revokeObjectURL are class (static) methods.

Don't use script-tests. It just doubles the number of files in the repo.

What? This is not an element. Can you add an assert that this does NOT work?

The correct usage of this should be:

var url = new webkitURL(urlString, baseUrlString);

> LayoutTests/fast/dom/DOMURL/script-tests/set-domurl-attribute-hash.js:8

This is also wrong. The constructor should not have any properties except for the two "static" methods, createObjectURL and revokeObjectURL.

var url = new URL('http://www.example.com/#hash-value');
shouldBeEqualToString('url.hash', 'hash-value');

Can you add tests that asserts that the constructor has the right static methods and that the instance has the expected properties and methods?

Use shouldThrow()

[Erik Arvidsson]

You also need to update DOMWindow.idl to remove/change the conditional for webkitURL.

We should also test that we have a stringifier for the href property. In other words toString should return href

var url = new webkitURL('http://www.example.com/');
shouldBe('url.toString()', 'url.href');

Thanx Erik. It is much useful. Just one question it should workin both ways 
var url = new webkitURL()
var url = window.webkitURL

Right?

var url = window.webkitURL;

works but it does not give you a URL instance. Instead it should give you a function object that can be used to construct new URL instances.

shouldBeFalse("'protocol' in webkitURL");
shouldBeFalse("'username' in webkitURL");
shouldBeFalse("'password' in webkitURL");
shouldBeFalse("'host' in webkitURL");
shouldBeFalse("'hostname' in webkitURL");
shouldBeFalse("'port' in webkitURL");
shouldBeFalse("'pathname' in webkitURL");
shouldBeFalse("'search' in webkitURL");
shouldBeFalse("'hash' in webkitURL");
shouldBeFalse("'filename' in webkitURL");
shouldBeFalse("'origin' in webkitURL");
shouldBeFalse("'parameterNames' in webkitURL");
shouldBeFalse("'getParametername' in webkitURL");
shouldBeFalse("'getParameterAllname' in webkitURL");
shouldBeFalse("'appendParameter' in webkitURL");
shouldBeFalse("'clearParametername' in webkitURL");
shouldBeFalse("'href' in webkitURL");

shouldBeTrue("createObjectURL' in webkitURL");
shouldBeTrue("'revokeObjectURL' in webkitURL");

Move all the single statement functions to the .h file

Why are you comparing to the string "null"?

Did you want to do?

if (value.isNull())
    return;

But the question is, do we really need to do this? Doesn't KURL::setProtocol work correctly with this in mind already?

> Source/WebCore/html/DOMURL.cpp:165
> +    KURL url = href();

m_href is mutable so there should be no need to make a copy of it, serialize it and reparse it.

void DOMURL::setProtocol(const String& value)
{
  m_href.setProtocol(value);
}

> Source/WebCore/html/DOMURL.cpp:190

void DOMURL::setPassword(const String& value)
{
  m_href.setPass(value);
}

> Source/WebCore/html/DOMURL.cpp:257

> +    if (!url.canSetHostOrPort())

Maybe do this before the loop?

This was to make sure that "#" in the search does not leak to hash. Do u think should be removed?

I thought that KURL would do the right thing but I see that it doesn't. I kind of wonder if it would not be cleaner to fix KURL here? (and remove this code from HTMLAnchorElement etc)

I landed the support for static.

The static keyword needs to come before the extended attributes.

static [Conditional=BLOB, ConvertNullStringTo=Undefined] DOMString createObjectURL(in Blob blob);

Its not working somehow. I get compilation errors for DerievedSources as the conversion becomes like this - 

static #ifdef BLOB createObjectURL(Blob* blob)

Patch

Tried to get the patch working somehow. Not sure if all correct yet. Erik, need some assistance in the patch. May be u can review and let me know missing parts. I found the problem in having "static" keyword before "[Conditional]". Its because there is function overloading in the idl file. When i removed one of them (MediaStream parameter API) it was building fine. But in normal case i get errors - 

DerivedSources/WebCore/JSDOMURL.cpp:554:1: error: stray ‘#’ in program
DerivedSources/WebCore/JSDOMURL.cpp:567:2: error: #endif without #if
DerivedSources/WebCore/JSDOMURL.cpp:569:1: error: stray ‘#’ in program
DerivedSources/WebCore/JSDOMURL.cpp:593:2: error: #endif without #if

This is bcoz it creates two separate static functions in JSDOMURL.cpp as - 
static EncodedJSValue JSC_HOST_CALL jsDOMURLConstructorFunctionCreateObjectURL1(ExecState* exec)
static EncodedJSValue JSC_HOST_CALL jsDOMURLConstructorFunctionCreateObjectURL2(ExecState* exec)

one for MediaStream & one for Blob.

These needs to be 

static [Conditional=BLOB] type name(params);

However, beware that you will need to keep the #if here since overloaded methods cannot have different Conditional. Maybe a comment is due?

Fixed idl and removed static initializers

[Erik Arvidsson]

Kaustubh: I uploaded a patch that compiles. I had to fix the IDL and fix the static initializers.

One thing that we need to do is to clean up the URLs created by createObjectURL when the context is destroyed. Before this change window.webkitURL returned an instance of DOMURL (which extends ContextDestructionObserver) which cause contextDestroyed to get called when the context was destroyed. In our case we might not have any ContextDestructionObserver but I think we can create one in createObjectURL.

Thanks a lot Erik. I got where I needed fixes. But somehow, the patch is still failing for gtk port for the same errors "static" for overloaded functions. I am trying to fix those and also implement ContextDestructionObvserver.

I'm not a webkit reviewer but I'm happy to give you feedback anyway.

This needs more tests. You need to test every property getter and setter and make sure that all the code paths are tested. For example, in DOMURL::setHost there are a lot of branches. You need to have about 10 different tests to cover all the possible branches in there.

I also feel like there is a bit too much logic in here. It seems like we could move more code into KURL.

> Source/WebCore/html/DOMURL.cpp:257
> +    unsigned port = value.toUInt();

How do we handle non numbers in value?

> Source/WebCore/html/DOMURL.cpp:282
> +    m_href.setQuery(newSearch);

I didn't see any change in KURL::setQuery to handle '#' in the search string. Please add a test that ensures that setting search with '#' works as expected.

These should be implemented before we expose these to JS.

> +        DOMString getParameter(in DOMString name);

I would remove these if you do not plan to implement them in the first patch.

Missing

DOMString[] getParameterAll(in DOMString name);

> Source/WebCore/page/DOMWindow.idl:816
> +        attribute DOMURLConstructor webkitURL;

Can you file a bug that this should be renamed to URLConstructor? We should never expose DOMURL to script.

> +shouldBeFalse("url.hasOwnProperty('clearParameter')")

The opposite case is also interesting. But in general it is better to actually test their functionality than their presence since the functionality will implicitly cover the presence.

shouldBeTrue("'getParameter' in url");

You need to test the setter too.

A few quick comments which are in no way comprehensive.

> Source/WebCore/html/DOMURL.cpp:36
> +#if ENABLE(BLOB)

Don't exclude headers using an"#if" (unless absolutely necessary in order to keep some platforms building). I don't think that is the case here.

> Source/WebCore/html/DOMURL.cpp:58
> +        : ContextDestructionObserver(scriptExecutionContext) { }

{} should be on the next lines.

> Source/WebCore/html/DOMURL.cpp:60
> +    virtual void contextDestroyed()

Should not be inlined in the class since we don't want this function inlined.

Note that this leaks in the same way the current class does.

contextDestroyed isn't guaranteed to be called before the destructor.

If the destructor is called first, then this clean up (for the registeries) should run still.

> Source/WebCore/html/DOMURL.cpp:74
> +        publicURLManagerMap().remove(context);

not threadsafe.

> Source/WebCore/html/DOMURL.cpp:92
> +    return staticPublicURLManagers;

Not threadsafe (which is bad because this can be used from workers).

> Source/WebCore/html/DOMURL.cpp:98
> +    OwnPtr<PublicURLManager>& manager = map.add(scriptExecutionContext, nullptr).first->second;

not threadsafe.

> Source/WebCore/html/DOMURL.h:45
> +    static PassRefPtr<DOMURL> create(const String& url) { return adoptRef(new DOMURL(url, emptyString())); }

Where are these called?

> Source/WebCore/html/DOMURL.idl:-32
> -        NoStaticTables

Why is this being removed?

afaik, It needs to be here since this is exposed in Web Workers.

(In reply to comment #55)
Hi David, thanks for the review. Please find my comments inline. 
This patch has been divided into two parts to make review/committing easy. One part of making createObjectURL & revokeObjectURL static has been already landed. I will be updating this patch soon and will update new one.

I agree with this. But in this scenario, the header under #if will be required only in that case. Unless otherwise it will get built but the only prob will be it will unnecessary increase code segment AFAIK. Please guide if wrong.

Corrected.

contextDestroyed will get called first whenever ContextDestructionObserver::contextDestroyed gets called. This will ensure the cleanup of data related to PublicURLManager class. As this class is inline completely I tried to keep functions as well inline.

Should I be using ThreadGlobalData for this? I'm not sure.

Updated with new URL specs.

Agree. Will need to put it back.
