Bug 44256 – [EFL] Private Browsing feature for WebKit-Efl

• Status: RESOLVED
• Resolution: INVALID
• Component: WebKit EFL

[Grzegorz Czajkowski]

This feature implement private browsing feature for WebKit-Efl. 

It allows to disable cache during private browsing mode. Feature creates new cookie jar for cookies when user turns on private browsing mode. When user turns off it default cookie jar is restored.

Private browsing feature for WebKit-Efl

[Gyuyoung Kim]

It seems to me that methods regarding cookie need to be moved to ewk_cookies.cpp.

Hello Antognolli,

How do you think about it ?

[Gyuyoung Kim]

Hello Grzegorz,

Could you please add "[EFL]" prefix to the title of this bug ?

[Rafael Antognolli]

Hi Grzegorz, just some comments about your patch:

First, I agree with Gyuyoung, I'd put the cookies part inside ewk_cookies.cpp. Another comment:

+Eina_Bool _ewk_replace_cookie_jar(Eina_Bool enable)
+{
+#if USE(SOUP)
+    static Eina_Bool current_status_of_pb = EINA_FALSE;
+
+    if (current_status_of_pb == enable)
+        return EINA_FALSE;

What does it mean if you return false here? I think in cases where the setting you are trying to put is valid, but is already set, you should don't do nothing and just return true, instead of false. If you want a different behavior, document it on the doxygen string of the function, since this is the default one for most of our functions.

And I also don't like the idea of these static variables inside the function. They seem a little lost inside it. A better approach would be to add it to a struct somewhere.

Another question is: does this conflict with the bug 44239 ? I think if you are in private browsing mode, maybe you shouldn't store any page for offline use. What do you think about this?

Regards,
Rafael

Looks reasonable.  This review is more of a rubber-stamp.

Actually, it's probably better to answer Rafael's questions before landing this patch.

Incognito feature for WebKit-Efl

[Grzegorz Czajkowski]

1) I moved a function _ewk_cookie_jar_replace to ewk_cookies.h

2) I changed the name of feature to Incognito Browsing Feature because WebKit already has private browsing for the Pages.

3) I changed condition - if we alredy are in incognito mode we return EINA_TRUE.

4) Needed information regarding to cookies are stored in Ewk_Incognito_Cookies struct. Definition of this struct is puted to ewk_cookies.cpp. I think it's not necessary to include it to ewk_cookies.h because only _ewk_jookie_jar_replace uses it.

5) Static variables are moved to _ewk_incognito_cookie_get() - they are needed in this case - I think.

6) Added docs.

7) Changelog has high-level summary.

I would like to know your opinion on that.
Thanks.

About the last patch:

+        Saves cookies to a new cookie jar, disables cache of WebCore and doesn't strore any pages for offline use.

Please, fix the typo ("strore").

+ * @param enable if @c EINA_TRUE creates a new cookie jar (all cookies will be saved to this one), c@ EINA_FALSE restores default cookie jar.

Another typo ("c@" instead of "@c").

+ * @return @ EINA_TRUE if cookie jar has been replaced/restored. @c EINA_FALSE otherwise or other error occured.

Another typo ("@" between return and EINA_TRUE shouldn't exist).

Other comments:

Could you change the name _ewk_cookie_jar_replace() to _ewk_cookie_jar_replace_set()? Or even something like _ewk_cookie_jar_fake_set(), or _ewk_cookie_jar_tmp_set()? Maybe it's just my opinion, but I believe that this is a little more descriptive...

I also believe that a better place for the function _ewk_cache_disable would be inside ewk_settings.cpp. What do you think about it?

Regards,

Rafael

That's a good idea. I changed it to _ewk_cookie_jar_fake_set().

Ok. I moved it and changed name to ewk_setting_disable_cache_set and exported it to public API.

>

I added comments to functions _ewk_incognito_cookie_get and _ewk_cookie_jar_fake_set that they aren't exported to public API.

I've fixed the build break because a file Cache.h has been renamed to MemoryCache.h.

I did a small changes in ewk_setting.cpp regarding to sorting problems of includes files. I hope that you don't mind on that :)

[Rafael Antognolli]

This name is really weird because there are 2 verbs "disable" and "set". Could you rename it to ewk_settings_cache_disabled_set?

> WebKit/efl/ewk/ewk_settings.cpp:307
> +    if (cache->disabled() != set) 

Since this is EAPI, you can't really trust user passed EINA_TRUE or EINA_FALSE. In some places we use to use "set = !!set;". Please either do this or check by "!set"

> WebKit/efl/ewk/ewk_view.h:538
> +EAPI Eina_Bool ewk_view_incognito_browsing_set(Evas_Object *o, Eina_Bool enable);

Follow the other cases on this header: it's Evas_Object* o, not Evas_Object *o

[Grzegorz Czajkowski]

Ok, I will fix this.
What about declaration of _ewk_cookie_jar_fake_set. This is internal method. Does it should be moved to ewk_private.h? If yes I suggest to remove prefix "_".

HUmn... you're right. Moreover, make _ewk_incognito_cookie_get() static.

Why should we return true unconditionally ?

Please reply to Gyuyoung's questions, and mine as well. A few style issues to be fixed, and it does not apply to ToT anymore (rebase needed).

> Source/WebKit/efl/ewk/ewk_settings.cpp:332

"*" is on the left side.

> Source/WebKit/efl/ewk/ewk_settings.h:54
> +EAPI Eina_Bool       ewk_settings_cache_disable_set(Eina_Bool set);

Is it common to have "disable_set" APIs instead of "enable_set"?

> Source/WebKit/efl/ewk/ewk_view.cpp:4439
> +    return (result_cookies && result_cache && result_offline_pages);

no parentheses needed.

ewk_settings.cpp already has ewk_settings_cache_enable_set(). You need to remove this function from this patch.

ewk_settings.cpp.
355 void ewk_settings_cache_enable_set(Eina_Bool set)
356 {
357     WebCore::MemoryCache* cache = WebCore::memoryCache();
358     set = !set;
359     if (cache->disabled() != set)
360         cache->setDisabled(set);
361 }

Yes, I've already moved this function because it can be used in general mode too.

I don't think that patch is needed since WebKit's private browsing has been extended a lot.
One method that is worth to submit is:
ewk_cookie_jar_fake_set which replaces/restores default cookie jar of Soup session.
Do we need this? What do you think?

Could you explain worth of the function ?

Grzegorz, if you think we need to have the "ewk_cookie_jar_fake_set()", please file a new bug. This bug is too old. I close this bug as invalid.
