1 2004-11-17  Darin Adler  <darin@apple.com>
2
3         Reviewed by Ken.
4
5         - fixed <rdar://problem/3885744> crash with XMLHttpRequest test page (reported by KDE folks)
6
7         * khtml/ecma/xmlhttprequest.cpp: (KJS::XMLHttpRequest::slotFinished):
8         Rolled in fix from KDE; make sure to set job to 0 before calling changeState.
9
10         - fixed <rdar://problem/3885729> attempting to modify a computed style does nothing, but should raise a DOM exception
11         - fixed <rdar://problem/3885731> style declarations use too many malloc blocks; switch to QValueList
12         - fixed <rdar://problem/3885739> DOM::NodeImpl accessor in DOM::Node class is hot; should be inlined
13         - changed NodeImpl calls like replaceChild to always ref/deref the parameter; this is a better way to fix
14           an entire category of leaks we have been fixing one by one recently
15         - changed computed styles so they hold a reference to the DOM node; the old code could end up with a
16           stale RenderObject pointer, although I never saw it do that in practice
17         - implemented the length and item methods for computed styles
18         - implemented querying additional properties in computed styles (29 more)
19
20         * khtml/khtml_part.h: Update forward declaration of CSSMutableStyleDeclarationImpl since it's
21         now a separate class rather than a typedef. Changed the parameter type of setTypingStyle to
22         take a mutable style.
23         * khtml/khtml_part.cpp:
24         (KHTMLPart::setTypingStyle): Change parameter to take a mutable style.
25         (KHTMLPart::applyStyle): Add code to make a mutable style in case we are passed
26         a computed style; also change some types to mutable style.
27         (updateState): Update iteration of CSSProperty objects in a style declaration to use
28         the new valuesIterator interface.
29         (KHTMLPart::selectionHasStyle): Add a call to makeMutable.
30         (KHTMLPart::selectionStartHasStyle): Add call to makeMutable and update iteration.
31         (editingStyle): Change type to mutable style, and simplify the style-creation calls,
32         including accomodating the exception code that setCssText has now.
33         (KHTMLPart::applyEditingStyleToElement): Change types to mutable style.
34         (KHTMLPart::removeEditingStyleFromElement): Change code to call setChanged only if removing
35         the style attributes really was a change, although it's not an important optimization it's
36         good to do it right.
37
38         * khtml/css/css_base.h: Remove unneeded setParsedValue method.
39         * khtml/css/css_base.cpp: Remove unneeded setParsedValue method. All the places that were
40         calling it were already removing the old property explicitly, so the code in here to remove
41         the property again was redundant.
42
43         * khtml/css/css_computedstyle.h: Updated virtual functions for changes to parameters in base class.
44         Moved all the "set"-type functions so they are private. Store a node pointer instead of a renderer.
45         * khtml/css/css_computedstyle.cpp:
46         (DOM::CSSComputedStyleDeclarationImpl::CSSComputedStyleDeclarationImpl): Hold a reference to
47         the node we compute style for, so we don't end up with a pointer to a deallocated RenderObject.
48         Before we had no guarantee the object would outlast us.
49         (DOM::CSSComputedStyleDeclarationImpl::setCssText): Add exception parameter, and set the
50         exception to NO_MODIFICATION_ALLOWED_ERR.
51         (DOM::CSSComputedStyleDeclarationImpl::getPropertyCSSValue): Update to use node pointer rather
52         than renderer pointer. Added implementation for box-align, box-direction, box-flex, box-flex-group,
53         box-lines, box-ordinal-group, box-orient, box-pack, caption-side, clear, cursor, direction,
54         list-style-image, list-style-position, list-style-type, marquee-direction, marquee-repetition,
55         marquee-style, user-modify, opacity, orphans, outline-style, page-break-after, page-break-before,
56         page-break-inside, position, unicode-bidi, widows, z-index.
57         (DOM::CSSComputedStyleDeclarationImpl::removeProperty): Add exception parameter, and set the
58         exception to NO_MODIFICATION_ALLOWED_ERR.
59         (DOM::CSSComputedStyleDeclarationImpl::setProperty): Ditto.
60         (DOM::CSSComputedStyleDeclarationImpl::length): Implemented.
61         (DOM::CSSComputedStyleDeclarationImpl::item): Implemented, calls getPropertyValue.
62         (DOM::CSSComputedStyleDeclarationImpl::copyInheritableProperties): Changed return type to
63         CSSMutableStyleDeclarationImpl.
64         (DOM::CSSComputedStyleDeclarationImpl::copy): Added.
65         (DOM::CSSComputedStyleDeclarationImpl::makeMutable): Added.
66
67         * khtml/css/css_ruleimpl.h: Update forward declaration of CSSMutableStyleDeclarationImpl since it's
68         now a separate class rather than a typedef.
69         * khtml/css/cssparser.h: Ditto.
70
71         * khtml/css/css_valueimpl.h: Refactor CSSStyleDeclarationImpl into two classes. New derived class
72         CSSMutableStyleDeclarationImpl has the guts, and the base class has only some virtual functions.
73         Removed a bunch of redundant stuff from other classes in this file too.
74         (DOM::DashboardRegionImpl::setNext): Ref new before deref'ing old to handle the set-to-same case.
75         (DOM::CSSProperty::CSSProperty): Added new overload so you can create a CSSProperty with initial values.
76         (DOM::CSSProperty::operator=): Added.
77         (DOM::CSSProperty::setValue): Use ref-before-deref pattern to simplify slightly.
78
79         * khtml/css/css_valueimpl.cpp:
80         (DOM::CSSStyleDeclarationImpl::CSSStyleDeclarationImpl): Remove uneeded things.
81         (DOM::CSSStyleDeclarationImpl::isStyleDeclaration): Put here now that it's no longer inline.
82         (DOM::CSSMutableStyleDeclarationImpl::CSSMutableStyleDeclarationImpl): Added.
83         (DOM::CSSMutableStyleDeclarationImpl::operator=): Added.
84         (DOM::CSSMutableStyleDeclarationImpl::~CSSMutableStyleDeclarationImpl): Updated.
85         (DOM::CSSMutableStyleDeclarationImpl::getPropertyValue): Removed now-uneeded check.

105         (DOM::CSSStyleDeclarationImpl::diff): Update to use QValueList.

528         Fixed a couple of object lifetime issues. The EditCommand class used to hold an
529         EditCommandPtr to its parent, but this caused a a reference cycle in composite 
530         commands as the children held a ref to their parent. Now, the parent variable

532         weak reference to the parent or even override deref in composite commands (but I
533         can't since deref() is not virtual). However, this should be OK since any

955         the code which runs in the StayInBlock case. This code was redundant, and caused
956         incorrect results to be returned in the DoNotStayInBlock case.

1391         Implemented command to insert a block in response to typing a return key (even though
1392         I am not turning that on by default with this patch....that will come later). 
1393         
1394         This new command is called InsertParagraphSeparatorCommand.
1395         
1396         Reworked the command and function names associated with inserting content into a 
1397         document. Before this patch, there were inputXXX and insertXXX variants, with the
1398         former used for more high-level actions and the latter used for lower-level stuff.
1399         However, this was confusing as the AppKit uses insertXXX for everything. This resulted
1400         in an insertXXX command going through an inputXXX WebCore step and then finally to an
1401         insertXXX WebCore step. To make this less confusing, I have changes all the names to
1402         be insertXXX, and modified the lower-level operations so that it is clear what they do.

1497         generalized copyPropertiesInSet function with the arguments needed to make copying
1498         inheritable work.
1499         * khtml/css/css_computedstyle.h:
1500         * khtml/css/css_valueimpl.cpp:

1502         In order to do apply block properties, "regular" style declarations need to do style
1503         diffs as well.
1504         (CSSStyleDeclarationImpl::copyBlockProperties): New helper. Just like copyInheritableProperties
1505         except that it uses a different set of properties that apply only to blocks.
1506         (CSSStyleDeclarationImpl::copyPropertiesInSet): New helper that looks at a style declaration
1507         and copies out those properties listed in a pre-defined set.

1516         style changes into different kinds. CSS specifies certain properties only apply to certain
1517         element types. This set of changes now recognizes two such separate cases: styles that apply
1518         to blocks, and styles that apply to inlines.

1523         done so that the function can be passed a portion of the styles being applied so that block styles
1524         and inline styles can be handled separately.

1534         it needs to layout, even though it has not changed position in the DOM. For instance, this is needed 
1535         when text align changes.
1536         * khtml/khtml_part.cpp:
1537         (KHTMLPart::setTypingStyle): Put in an early bail-out in the case where the current style matches
1538         the passed-in argument.
1539         (KHTMLPart::applyStyle): Modify this function so that block styles are applied when the selection
1540         is a caret. Formerly, this just set typing style and made no visible changes to the document.

2089         - follow-on to my fix yesterday, which broke a layout test because I rolled out a fix that Maciej had done
2090
2091         * khtml/html/htmltokenizer.cpp: (khtml::HTMLTokenizer::write): Need to check the actual queue of external
2092         scripts being loaded here. If the current code being run is the external script itself, then we don't want
2093         to defer parsing. But loadingExtScript has to stay true until after the script runs. The old code would
2094         assume that any time we're running a script there's no need to look at loadingExtScript, but that was also
2095         wrong since there can be a script loading in that case too. Layout tests check for both problems.

2108
2109         * khtml/html/htmltokenizer.cpp:
2110         (khtml::HTMLTokenizer::scriptHandler): Use !isEmpty instead of count != 0, since it's cheaper.
2111         (khtml::HTMLTokenizer::write): Roll back to the old version of the check here. The fix is that

2124         Also changed the return value to be DOMString, rather than DOMStringImpl, to deal with the

2171
2172         * khtml/editing/visible_position.cpp:
2173         (khtml::VisiblePosition::deepEquivalent): Remove code that attempted to bridge old-style
2174         position code to new-style VisiblePosition code. In retrospect, this code was misguided.
2175         Since we do a good job of insulating external code from the internal workings of 
2176         VisiblePosition, the "hop ahead" being done here was not doing anyone any real good, and

2322         Fix for this bug:
2323         
2324         <rdar://problem/3816768> REGRESSION (Mail): Deleting last character in block incorrectly 
2325         moves caret out of block.
2326
2327         The issue here is that an empty block with no explicit height set by style collapses
2328         to zero height, and does so immediately after the last bit of content is removed from
2329         it (as a result of deleting text with the delete key for instance). Since zero-height
2330         blocks are not eligible caret positions, the caret jumped to the closest eligible spot.
2331         
2332         The fix is to detect when a block has not been removed itself, but has had all its 
2333         contents removed. In this case, a BR element is placed in the block, one that is
2334         specially marked as a placeholder. Later, if the block ever receives content, this
2335         placeholder is removed.

2342         Also, do some cleanup on some old, crufty code in the move logic that is just so clearly wrong 
2343         (it's very clear that we needs to be able to move more than just text nodes). This may expose
2344         bugs, but these bugs needs to be filed and fixed, not ducked. Besides, undoing this silliness
2345         made the test case in the bug work.
2346         (khtml::DeleteSelectionCommand::doApply): Call insertBlockPlaceholderIfNeeded and

2581         (DOM::HTMLInputElementImpl::reset): Changed to only nuke the value if the value property is stored
2582         separately from the attribute. Otherwise, we just want to lave it alone
2583         (DOM::HTMLInputElementImpl::value): Changed to always use m_value if it's not null, then fall back
2584         on the attribute, and finally fall back to the "on" for the checkbox only if both are null.
2585         (DOM::HTMLInputElementImpl::setValue): Changed to set the attribute unless the value property is
2586         supposed to be stored separate from the attribute.

2751         - fixed <rdar://problem/3828147> REGRESSION: textareas with wrap="off" show their contents in a thin vertical line of text
2752
2753         * kwq/KWQTextArea.h: Added setTextColor and setBackgroundColor methods. This is really for another fix
2754         I'm landing later, but it does no harm to add these now.
2755         * kwq/KWQTextArea.mm:
2756         (-[KWQTextArea _configureTextViewForWordWrapMode]): Set the container size after changing the flag that
2757         determines if the width tracks the text view. Otherwise, we won't successfully set the width in the case
2758         where we don't want it to track the text view. This caused the bug. 
2759         (-[KWQTextArea _createTextView]): Remove unneeded call to setMaxSize. The above method already does that.
2760         (-[KWQTextArea setTextColor:]): Added.

2766
2767         - fixed <rdar://problem/3829452> REGRESSION (156-157): onload handler doesn't run on page with meta refresh of 0 duration (new Apple start page)
2768
2769         The fix for <rdar://problem/3773150> made it so <meta> redirects prevent tokenizing the rest of the page.
2770         This is incorrect; the reason the JavaScript-triggered loads prevent tokenizing is that they take place
2771         "right away" in other browsers, but that is not true of <meta> redirect. We fixed this by using a separate
2772         call for <meta> redirect and not preventing tokenizing when that's in effect.
2773
2774         * khtml/khtml_part.h: Removed userGesture parameter from scheduleRedirection. Renamed
2775         isImmediateRedirectPending to isScheduledLocationChangePending. Added scheduleLocationChange.
2776         * khtml/khtml_part.cpp:
2777         (KHTMLPart::openURL): Updated for new constant name.
2778         (KHTMLPart::scheduleRedirection): Removed now-unneeded userGesture parameter, and removed code that
2779         does the special case for redirection during load; a <meta> refresh can never be one of those special
2780         redirects during a load because it redirects the frame itself, not another frame. Also tightened up
2781         the logic by always stopping the redirect timer even if we aren't restarting it.
2782         (KHTMLPart::scheduleLocationChange): Added. Like scheduleRedirection, but with a different constant
2783         so we can tell it apart and always a delay of 0. The "redirection during load" case was moved in here
2784         and renamed to locationChangeScheduledDuringLoad.
2785         (KHTMLPart::isScheduledLocationChangePending): Renamed from isImmediateRedirectPending. This now
2786         returns true only for location changes and history navigation, not <meta> redirects.
2787         (KHTMLPart::scheduleHistoryNavigation): Tightened up logic to do the stop() outside the if as above,
2788         and got rid of a silly timer delay computation that always resulted in 0.
2789
2790         * khtml/khtmlpart_p.h: Added a new value to the RedirectionScheduled enum for scheduleLocationChange
2791         and also renamed one of the existing values.
2792
2793         * khtml/html/htmltokenizer.cpp: (HTMLTokenizer::write): Changed to use isScheduledLocationChangePending instead
2794         of isImmediateRedirectPending, because we do want to continue tokenizing if it's actually a redirect.
2795
2796         * khtml/ecma/kjs_html.cpp: (KJS::HTMLDocument::putValue): Changed to call the new scheduleLocationChange
2797         instead of calling scheduleRedirection with delay of 0.
2798         * khtml/ecma/kjs_window.cpp:
2799         (Window::put): Ditto.
2800         (WindowFunc::tryCall): Ditto.

2816         - fixed <rdar://problem/3804665> REGRESSION: WebCore framework now has many init routines
2817
2818         * khtml/xml/dom_nodeimpl.h: Changed anyQName declaration to not use the inline function
2819         makeId. Surprisingly, the inline function was not "constant-folded" and we ended up with
2820         a copy of the function in each file as an init routine for the framework.
2821
2822         * khtml/ecma/kjs_html.cpp: (Gradient::colorStops): Get rid of initialized ColorStop
2823         globals; their constructors were showing up as init routines for the framework.
2824
2825         * khtml/rendering/render_style.h: Got rid of inline initialDashboardRegions function.
2826         * khtml/rendering/render_style.cpp: (RenderStyle::initialDashboardRegions): Made this
2827         a normal function. When it was an inline function, the constructors for the per-file
2828         copies of the globals were showing up as init routines for the framework.

3143
3144         * khtml/editing/selection.cpp:

3155         non-breaking spaces was causing errors when the new -khtml-nbsp-mode was set to "space".
3156         (khtml::RenderBlock::computeHorizontalPositionsForLine): Shrink line boxes that

3174         Fix for these bugs:

3176         In this patch, I add two new CSS properties and their associated behavior.
3177         This is to support end-of-line and word-wrapping features that match the

3181         for using these new properties to bring about the desired editing behavior.
3182

3761
3762         * khtml/html/htmltokenizer.cpp:
3763         (khtml::HTMLTokenizer::parseTag):
3764         add "application/x-javascript" to the list of legal scripting types. Mozilla
3765         accepts this, but WinIE doesn't.

3768         updated layout test to test some application/xxxx types

3772         Reworked lists to work well with RTL text.  Specifically the following bugs have been fixed:
3773
3774         (1) All bullets use the same offset constant now (a padding of 7 pixels).  Before, images used 5 and others used 7.
3775         (2) Line height now works properly, so that list items with no content aren't squished (and missing the line descent).
3776         (3) Punctuation now works correctly with inside and outside style ordered lists in RTL.
3777         (4) RTL lists now properly apply padding and margin to the right side rather than the left.  This was done by adding
3778         -khtml-margin-start and -khtml-padding-start properties that are just mapped to left/right based off the direction.

3806         Mark the VisiblePosition taking (Position &, EAffinity=DOWNSTREAM) explicit. Recently, when I added
3807         the EAffinity argument, I left this constructor implicit. Darin pointed out to me that this is
3808         undesirable since implicit use of the the constructor involved making the affinity choice, something
