For the last page, here is the final three messages sent between the content
process, RemotePrintJobChild, and the chrome process, RemotePrintJobParent, for
printing:
1. The content process sends *ProcessPage* to the chrome process via
SendProcessPrint to request the chrome process print the last page.
2. The content process sends *FinalizePrint* to the chrome process via
SendFinalizePrint to notify the chrome that there are no more outstanding
print requests, and that the chrome process can release interal resource
now.
3. The content process receive PageProcessed message from the chrome process.
This calling sequence is fine for sync style PrintTarget (even though the
FinalizePrint message is sent out a bit ealy). Since a sync PrintTarget
completes its print task right after receiving *ProcessPage* message in #1,
sending FinalizePrint before getting PageProcessed response is harmless.
But this message dispatching sequence does cause a problem for async style
PrintTargetEMF. After getting a message sent in #2, PrintTargetEMF release all
resources before getting a EMF conversion response from the PDFium process. So
the last page can not be printed correctly. This patch reorder the #2 and #3
message, that is to send FinalizePrint after the content process received
PageProcessed message of the last page.

Prior to this change, we would print a selection by:
* reflowing the whole document into one infinitely long page
* position at the top of the selection to print the first page
* move the position down by a page length each time to print subsequent pages
This has several shortcomings, detailed in the bug.
This approach uses the original document selection to create an inverted
selection in the document cloned for printing, adding an ellipsis when ranges
start or end in text nodes, then deletes that selection from the document prior
to printing.
This makes it API compatible with std::ostream, which it replaced. This silences a rare crash.

With previous change, KeyboardEvent is dispatched even when invisible window
has focus. However, nsRootWindow::GetControllerForCommand() returns controller
for focused window even when the window is invisible because it uses
nsFocusManager::GetFocusedDescendant() to retrieve focused window.
Perhaps, we can assume that users won't expect to do something with invisible
window when they type some keys. Then, nsRootWindow::GetControllerForCommand()
should return controller for visible ancestor window if focused window is
invisible.
This patch makes nsFocusManager::GetFocusedDescendant() can return only visible
descendants. However, it already has a bool argument. Therefore, it should
have a flag instead of adding new flag. Most changes of this patch is replacing
its callers.
Then, nsRootWindow::GetControllerForCommand() and nsRootWindow::GetControllers()
should have a bool flag if it should return controller(s) for visible window.
This patch adds a bool flag for it. Fortunately, the interface isn't scriptable.
Finally, this patch makes nsXBLPrototypeHandler::DispatchXBLCommand() and
EventStateManager::DoContentCommandEvent() retrieve controller for visible
window since they are always handles user input.

Bug 1376693 added a null-check to bail from print operations if
mPresShell/mPresContext are null, to avoid some null-deref crashes. However,
it turns out it's possible for these variables to be null under normal
conditions -- for example, when nsPrintEngine is printing documents,
mPrt->mPrintObject->mPresShell and mPrt->mPrintObject->mPresShell can be nullptr
if the document has <frameset> element and it's printing only content of a
<frame> element or all <frame> elements separately.
This special frameset-printing mode can cause these variables to be null;
however, the crash occurred only when mIsCreatingPrintPreview is true. So,
we should check the variables only when it's true.
Fortunately:
* the null-deref crashes that Bug 1376693 wanted to avoid were all in code
that we only visit when mIsCreatingPrintPreview is true (i.e. during print
preview).
* this special frameset-printing mode (which causes these variables to be
null) _cannot be used during print preview_.
So, we can avoid the print-preview-specific crashes without breaking
frameset-printing by simply making our null-check bail-out conditional on
mIsCreatingPrintPreview.

nsPrintObject::mPresShell and nsPrintObject::mPresContext are initialized by
nsPrintEngine::ReflowPrintObject(). However, while
nsPrintEngine::DoCommonPrint() is initializing mPrt and mPrintObject,
destroying nsAutoScriptBlocker may cause calling nsDocumentViewer::Destroy()
or nsPrintEngine::FinishPrintPreview() directly. Then,
nsPrintEngine::SetupToPrintContent() will be called. Therefore,
nsPrintEngine::SetupToPrintContent() sometimes see uninitialized mPrt, or
mPrt->mPrintObject->mPresShell and mPrt->mPrintObject->mPresContext.
Therefore, this patch makes nsPrintEngine::SetupToPrintContent() check whether
the necessary objects are already initialized. When one of them is not
initialized as expected, it won't to do anything.
Note that mPrt->mPrintObject is never nullptr with current design, but this

Most of the names passed to nsIStringBundle::{Get,Format}StringFromUTF8Name
have one of the two following forms:
- a 16-bit C string literal, which is then converted to an 8-bit string in
order for the lookup to occur;
- an 8-bit C string literal converted to a 16-bit string, which is then
converted back to an 8-bit string in order for the lookup to occur.
This patch introduces and uses alternative methods that can take an 8-bit C
string literal, which requires changing some signatures in other methods and
functions. It replaces all C++ uses of the old methods.
The patch also changes the existing {Get,Format}StringFromName() methods so
they take an AUTF8String argument for the name instead of a wstring, because
that's nicer for JS code.
Even though there is a method for C++ code and a different one for JS code,
|binaryname| is used so that the existing method names can be used for the
common case in both languages.
The change reduces the number of NS_ConvertUTF8toUTF16 and
NS_ConvertUTF16toUTF8 conversions while running Speedometer v2 from ~270,000 to
~160,000. (Most of these conversions involved the string
"deprecatedReferrerDirective" in nsCSPParser.cpp.)

This is the bulk of the changes.
- DisplayItemScrollClip is removed. Instead, we will have 1) ActiveScrolledRoot
and 2) DisplayItemClipChain.
- ActiveScrolledRoot points to a scroll frame and allows traversing up the
scroll frame chain.
- DisplayItemClipChain is a linked list of clips, each clip being associated
with the ActiveScrolledRoot that moves this clip.
- Each display item has an ActiveScrolledRoot and a clip chain.
- nsDisplayItem::GetClip returns the item of the clip chain that scrolls with
the item's ASR. The separation between "regular clip" and "scroll clips"
mostly goes away.
- Tracking clips in the display list builder's clip state happens very
similarly to how regular clips used to be tracked - there's a clip chain for
content descendants and a clip chain for containing block descendants. These
clip chains are intersected to create the combined clip chain.
- There are strict rules for the ASR of a container item: A container item's
ASR should be the innermost ASR which the item has finite clipped bounds with
respect to.
- At some point in the future, ASRs and AGRs should be reunified, but I haven't
done that yet, because I needed to limit the scope of the change.

This has two improvements.
- The condition is not evaluated in non-debug builds.
- The sense of the condition is inverted to the familiar "this condition should
be true" sense used in assertions.
A common variation on the side-effect-free case is the following.

They happen because we have a wrap list item that contains an out of flow frame with no saved clip data. So the patch for this bug changes the scroll clip of the wrap list item from the scroll clip induced by the root scroll frame to the null scroll clip. All of the display items that the wrap list contains have the root scroll frame scroll clip, so this causes the scroll clipped bounds for the wrap list item to expand to the whole content area. These expanded bounds of the wrap list item get incorporated into the bounds of a parent transform item. Later the wrap list item is flattened away, and so it's no longer around to provide the expanded bounds, leading to the assertions.
I've thought through options like changing how scroll clipped bounds work for wrap list items, but I can't seem to find any solution that would be consistent. The best thing would be to get the proper clip on out of flows we are going to descend into, but I can't think of a good way to do that either in this case (or in general).
The asserts are:
###!!! ASSERTION: Bounds computation mismatch: 'mContainerBounds.IsEqualInterior(mAccumulatedChildBounds)', /layout/base/FrameLayerBuilder.cpp, line 4887
###!!! ASSERTION: bad aListVisibleBounds: 'r.GetBounds().IsEqualInterior(aListVisibleBounds)', /layout/base/nsDisplayList.cpp, line 1637
They happen because we have a wrap list item that contains an out of flow frame with no saved clip data. So the patch for this bug changes the scroll clip of the wrap list item from the scroll clip induced by the root scroll frame to the null scroll clip. All of the display items that the wrap list contains have the root scroll frame scroll clip, so this causes the scroll clipped bounds for the wrap list item to expand to the whole content area. These expanded bounds of the wrap list item get incorporated into the bounds of a parent transform item. Later the wrap list item is flattened away, and so it's no longer around to provide the expanded bounds, leading to the assertions.

This patch defines mozilla::SelectionType as an enum class. This is safer than nsISelectionController::SELECTION_* since setting illegal value to its variable is checked at build time. So, as far as possible, this should be used everywhere (but of course, this isn't available in scriptable interfaces).
And also this implements some useful methods for managing SelectionType and RawSelectionType which are implemented in layout/nsSelection.cpp because nsISelectionController is implemented by both PresShell and nsTextEditorState. Therefore, implementing one of them may make hard to find them. On the other hand, nsSelection.cpp is a better file name to look for them.
Note that this patch creates mozilla::Selection::RawType() for binding. Native code should keep using Selection::Type() but the binding code needs to use RawType() due to impossible to convert from SelectionType to RawSelectionType without explicit cast.

And mCharCode shouldn't be compared with NS_VK_*, nsIDOMKeyEvent::DOM_VK_*. Additionally, when it's compared with a character constant, cast isn't necessary.

We create and destroy ScaledFonts for every piece of text we write.
That causes a huge amount of duplicated data within the recording.
This splits out the recording of the font data itself from the ScaledFont.
The key generated to determine uniqueness could probably be fairly easily faked, but for our purposes that doesn't matter.
In theory these lookups should never fail.
The plan is to move them to release asserts when any bugs have been fixed, as failed lookups may be an indication of data being sent from a compromised renderer.
Adds a new timer for the RemotePrintJob to notify the nsPagePrintTimer when the last page has finished printing in the parent.
Changed the page delay timer to reset the watch dog count on every page to prevent timeouts due to remote printing.
This also changes aPrintToFileName parameter for BeginDocument to an nsAString& from char16_t*.
Having a char16_t* caused a pain with VS2105 where wchar_t != char16_t (as on VS2103), after it had been sent over IPDL.
This could have been worked around with casting, but this seemed like the tidier solution.

The first four arguments of GetPageRangeForSelection() are not used usefully,
nor are the first two arguments of FindSelectionBounds() and
FindSelectionBoundsWithList(). (Mutual recursion between the latter two
obscured this fact.)

The print engine used to directly cause a prompt to be displayed in the most
recent window in the event of an error. This patch causes the print engine to
fire an event instead so that the front-end can choose to display or ignore
the error.

The patch removes 455 occurrences of FAIL_ON_WARNINGS from moz.build files, and
adds 78 instances of ALLOW_COMPILER_WARNINGS. About half of those 78 are in
code we control and which should be removable with a little effort.

This is straightforward mapping of PR_LOG levels to their LogLevel
counterparts:
PR_LOG_ERROR -> LogLevel::Error
PR_LOG_WARNING -> LogLevel::Warning
PR_LOG_WARN -> LogLevel::Warning
PR_LOG_INFO -> LogLevel::Info
PR_LOG_DEBUG -> LogLevel::Debug
PR_LOG_NOTICE -> LogLevel::Debug
PR_LOG_VERBOSE -> LogLevel::Verbose
Instances of PRLogModuleLevel were mapped to a fully qualified
mozilla::LogLevel, instances of PR_LOG levels in #defines were mapped to a
fully qualified mozilla::LogLevel::* level, and all other instances were
mapped to us a shorter format of LogLevel::*.
Bustage for usage of the non-fully qualified LogLevel were fixed by adding
|using mozilla::LogLevel;| where appropriate.
