Boris Zbarsky 4530e9a97e Bug 1560055 part 5. Fix various reflection cases that should be using GetUnsignedIntAttr but are using GetIntAttr. r=mccr8
It mostly works out, because we return an int32_t then just cast it to uint32_t,
but it would be better to return the right thing to start with.

Emilio Cobos Álvarez 6917a38081 Bug 1555216 - Change the signature of BindToTree to be (BindContext&, nsINode& aParentNode). r=bzbarsky
BindContext was going to have way more information at first, but then I realized
that most of the things I wanted to know were basically a flag away using the
parent node.

Still I think it's worth it, now experimenting with BindToTree will only mean
adding a field to a struct that's included from a couple cpp files, instead of a
massive pain.

I also think this is clearer, and doing this highlights quite a few
inconsistencies in our code which I've left untouched, but commented with
FIXMEs.

Steps are:

$ for file in $(rg 'nsresult BindToTree\(' | cut -d : -f 1 | sort | uniq); do sed -i 's#nsresult BindToTree(Document\* aDocument, nsIContent\* aParent,#nsresult BindToTree(BindContext\&, nsINode\& aParent)#g' $file; done
$ for file in $(rg 'nsresult BindToTree\(' | cut -d : -f 1 | sort | uniq); do sed -i 's#                      nsIContent\* aBindingParent) override#override#g' $file; done
$ for file in $(rg '::BindToTree\(' | cut -d : -f 1 | sort | uniq); do sed -i 's#::BindToTree(Document\* aDocument, nsIContent\* aParent,#::BindToTree(BindContext\& aContext, nsINode\& aParent)#g' $file; done
$ for file in $(rg '::BindToTree\(' | cut -d : -f 1 | sort | uniq); do sed -i 's#nsIContent\* aBindingParent)##g' $file; done
$ for file in $(rg '::BindToTree\(' | cut -d : -f 1 | sort | uniq); do sed -i 's#::BindToTree(aDocument, aParent, aBindingParent)#::BindToTree(aContext, aParent)#g' $file; done
$ ./mach clang-format

Then manual fixups.

Depends on D32948

Emilio Cobos Álvarez ff732c2cdf Bug 1555143 - Remove unused aDeep argument from UnbindFromTree. r=bzbarsky
$ for file in $(rg UnbindFromTree | cut -d : -f 1 | sort | uniq); do sed -i 's#UnbindFromTree(bool aDeep = true,#UnbindFromTree(#g' $file; done
$ for file in $(rg UnbindFromTree | cut -d : -f 1 | sort | uniq); do sed -i 's#UnbindFromTree(bool aDeep,#UnbindFromTree(#g' $file; done

And fix the two callers and little use of the aDeep argument (see the "Manual

Emilio Cobos Álvarez d2ed260822 Bug 1517241 - Rename nsIDocument to mozilla::dom::Document. r=smaug
Summary: Really sorry for the size of the patch. It's mostly automatic
s/nsIDocument/Document/ but I had to fix up in a bunch of places manually to
add the right namespacing and such.

Overall it's not a very interesting patch I think.

nsDocument.cpp turns into Document.cpp, nsIDocument.h into Document.h and
nsIDocumentInlines.h into DocumentInlines.h.

I also changed a bunch of nsCOMPtr usage to RefPtr, but not all of it.

While fixing up some of the bits I also removed some unneeded OwnerDoc() null
checks and such, but I didn't do anything riskier than that.

Masayuki Nakano 0acd37ec1d Bug 1504911 - part 4: Make all script for web content dispatch "input" event with proper event interface r=smaug
Currently, some "input" event dispatchers in our script dispatch "input" event
with UIEvent.  This is completely wrong.  For conforming to HTML spec, Event
is proper event.  Additionally, for conforming to Input Events, InputEvent
is proper event only on <textarea> or <input> element which has a single line
editor.

For making us to maintain easier, this patch adds new API, "isInputEventTarget"
to MozEditableElement which returns true when "input" event dispatcher should
use InputEvent for the input element.

Finally, this makes some dispatchers use setUserInput() instead of
setting value and dispatching event by themselves.  This also makes
us to maintain them easier.

Note that this does not touch "input" event dispatchers which dispatch events
only for chrome (such as URL bar, some pages in about: scheme) for making
this change safer as far as possible.

Masayuki Nakano cc3adb8c9e Bug 1504911 - part 2: Make nsTextEditorState::SetValue() dispatch "input" event if it's called for handling part of user input r=smaug
When editor is modified as part of user action, aFlags of
nsTextEditorState::SetValue() includes eSetValue_BySetUserInput.  In this case,
TextEditor (if there is) or the method itself (if there is no editor yet)
should dispatch "input" event by themselves because we will need to initialize
InputEvents more since we're going to implement Input Event specs.

Note that even with this patch, password field stops dispatching "input" event
with call of HTMLInputElement::SetUserInput().  This is caused by a hidden bug
of TextEditRules.   This will be fixed in a following patch.

Masayuki Nakano abe138f771 Bug 1504911 - part 1: Make all "input" event dispatcher in C++ use new utility method r=smaug
Currently, a lot of code dispatch "input" event and some of them dispatch
"input" event with wrong interface and/or values.  Therefore this patch
creates nsContentUtils::DispatchInputEvent() to make all of them dispatch
correct event.

Unfortunately, due to bug 1506439, we cannot set pointer to refcountable
classes of MOZ_CAN_RUN_SCRIPT method to nullptr.  Therefore, this patch
creates temporary RefPtr<TextEditor> a lot even though it makes damage to
the performance if it's in a hot path.

This patch makes eEditorInput event dispatched with
InternalEditorInputEvent when "input" event should be dispatched with
dom::InputEvent.  However, this patch uses WidgetEvent whose message is
eUnidentifiedEvent and setting WidgetEvent::mSpecifiedEventType to
nsGkAtoms::oninput when "input" event should be dispatched with
dom::Event because we need to keep that eEditorInput and
InternalEditorInputEvent are mapped each other.

Nathan Froyd 846d8789ee Bug 1492894 - part 1 - make the node hierarchy consistently constructed with NodeInfo&&; r=mccr8
Various places in dom/ use the pattern:

  already_AddRefed<NodeInfo> ni = ...;

which is supposed to be disallowed by our static analysis code, but
isn't, for whatever reason.  To fix our static analysis code, we need to
eliminate instances of the above pattern.

Unfortunately, eliminating this pattern requires restructuring how Nodes
are created.  Most Node subclasses take `already_AddRefed<NodeInfo>&` in
their constructors, and a few accept `already_AddRefed<NodeInfo>&&`.  We
need to enforce the latter pattern consistently, which requires changing
dozens of source files.

Emilio Cobos Álvarez 8f34c12e14 Bug 1479860: Remove unused aCompileEventHandlers argument from BindToTree. r=bz
Mostly automatic via sed. Only parts which I touched manually (apart from a
couple ones where I fixed indentation or which had mispelled arguments) are the
callers. I may have removed a couple redundant `virtual` keywords as well when
I started to do it manually, I can revert those if wanted.

Most of them are just removing the argument, but in Element.cpp I also added an
assertion for GetBindingParent when binding the ShadowRoot's kids (the binding
parent is set from the ShadowRoot constructor, and I don't think we bind a
shadow tree during unlink or what not which could cause a behavior difference).

In order to speed up Required/IsRequired(), instead of querying for the
@required attribute, we're now using the NS_EVENT_STATE_REQUIRED flag to know
whether an element's value is required.

For this to work correctly, we need to set NS_EVENT_STATE_REQUIRED earlier,
that is, in AfterSetAttr(), before any consumer of IsRequired(). We also need
to update or clear our required states when input type changes, since we may
have changed from a required input type to a non-required input type or
vice versa.

Note that NS_EVENT_STATE_REQUIRED/OPTIONAL is now part of the
EXTERNALLY_MANAGED_STATES.

Masayuki Nakano 7ad4ad3aab Bug 1374207 - part1: nsTextEditorState should use mozilla::TextEditor instead of editor interfaces r=smaug
Using concrete class rather than interface classes (nsI*Editor) will allow to reduce QI and some virtual calls.  Therefore, Editor classes should be used as concrete class as far as possible.

Unfortunately, if classes referring editor are initialized via scriptable interface, we cannot do this because nsI*Editor is still not marked as builtinclass.  Therefore, their editor may be implemented by JS.  E.g., inline nsIInlineSpellChecker.init() and nsIDocShell.editor.  Such remaining cases should be fixed after nsI*Editor classes are marked as builtinclass.

Note that this patch also creates nsIdentifierMapEntry.h which is separated from nsDocument.h because ShadowRoot.h needs the class but exposing nsDocument.h to the global and includes it causes bustage on Linux and Android.  Therefore, for fixing the include hell, this patch touches them and ContentChild.cpp.

Kirk Steuber e74f1cd513 Bug 1363481 - Add the old attribute value as a parameter to Element::AfterSetAttr r=bz
In order to facilitate the movement of code with side-effects called by Element::SetAttr to Element::BeforeSetAttr and Element::AfterSetAttr, Element::AfterSetAttr should have access to the old value of the attribute. This includes information about whether there was previously a value set or not.

Accomplishing this involved passing an additional argument through functions that find and change the old attribute value in order to ensure that we can differentiate between an empty old value and an absent old value (attribute was not set).

Note that while I tried to ensure that accurate values (and their absence) are reported to Element::AfterSetAttr, I largely ignored SVG. While the old value reported for SVG values should be however accurate the value already being reported to SetAttrAndNotify was, SVG elements do not currently report unset values properly because they will never pass a null pointer to SetAttrAndNotify.

Kirk Steuber 7fdb378650 Bug 1359556 - Optimize cloneNode by preinitializing attribute and child arrays r=bz
Currently, attribute and child arrays (implemented in dom/base/nsAttrAndChildArray.h) start out empty. When cloning, the array ends up being resized multiple times in order to add the attributes and children that are being cloned from the original node. This would be quicker if the array was initialized to the correct size in the first place so that resizes are not necessary.

However, preallocating space for children is only necessary when performing a deep clone. Therefore, an additional parameter is being added to the Clone, CopyInnerTo, and CloneDocHelper methods to indicate whether preallocation of children should happen. Attributes are copied either way, so that part of the array is preallocated in both cases.

Boris Zbarsky 8a2f1929a5 Bug 1343037 part 17. Remove the now-unused nsITextControlElement::GetSelectionRange. r=ehsan
This makes GetSelectionRange non-virtual on HTMLInputElement and HTMLTextareaElement.

Boris Zbarsky 5ae7da9d14 Bug 1343037 part 6. Simplify the setup around the editor state's GetSelectionRange function. r=ehsan
Really, there are only two cases we need to worry about.  Either
IsSelectionCached(), and then our SelectionProperties has the data we want, or
not and then we have a non-null mSelCon which has the data we want.

Since we are now using cached selection state a lot more (instead of
initializing the editor whenever someone asks for selection state), we need to
actually update it more correctly when .value is set.

And since we now update the cached selection state for the case when .value has
been set (to point to the end of the text), we need to change
HTMLInputElement::HasCachedSelection to return false for that case.  Otherwise
we will always do eager editor init on value set.  We handle that by not doing
eager init if the cached selection is collapsed.

The web platform test changes test the "update on .value set" behavior.  They
fail without this patch, pass with it.
