This patch was generated automatically by the "modeline.py" script, available
here: https://github.com/amccreight/moz-source-tools/blob/master/modeline.py
For every file that is modified in this patch, the changes are as follows:
(1) The patch changes the file to use the exact C++ mode lines from the
Mozilla coding style guide, available here:
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Mode_Line
(2) The patch deletes any blank lines between the mode line & the MPL
boilerplate comment.
(3) If the file previously had the mode lines and MPL boilerplate in a
single contiguous C++ comment, then the patch splits them into
separate C++ comments, to match the boilerplate in the coding style.

Bug 1400459 devirtualized nsIAtom so that it is no longer a subclass of
nsISupports. This means that nsAtom is now a better name for it than nsIAtom.

nsReflowStatus::IsEmpty() assertions are added after DISPLAY_REFLOW in the
beginning of the Reflow().
A few Reflow() implementations have Reset() calls at the end which are left
in place by this patch (with an explanatory comment added to each). These
ending Reset()s are only needed for cases where a non-splittable frame
passes its own nsReflowStatus to a child's reflow method. Just in case the
child leaves a "not fully complete" value in the nsReflowStatus, the
non-splittable parent frame must clear out the nsReflowStatus before
returning, so that its own parent doesn't then try to split it.

nsIFrame::mClass is of type enum class nsQueryFrame::ClassID which is
a strict subset of the nsQueryFrame::FrameIID values. For a concrete
frame class, its FrameIID is the same numeric value as its ClassID.

This makes it so that, given a |const nsIFrame*|, a caller can retrieve
properties but not set or remove them, but with an |nsIFrame*| all
operations are allowed. I believe this is sensible since properties act
as extended member variables for things that are needed rarely, and
these are the const-ness semantics of member variables.
This also avoids the need for const_cast<nsIFrame*> to cast away const
in the following patch, which guards property access with a frame state
bit.

This patch was written with the help of the following script. Also, manually
add mozilla qualifier to the enum values in nsStyleCoord.h, gfxRect.h, and
Types.h to make it build.
function rename() {
find .\
-type f\
! -path "./obj*"\
! -path "./.git"\
! -path "./.hg"\
\( -name "*.cpp" -or\
-name "*.h" \)\
-exec sed -i -e "s/$1/$2/g" "{}" \;
}
rename "NS_SIDE_TOP" "eSideTop"
rename "NS_SIDE_RIGHT" "eSideRight"
rename "NS_SIDE_BOTTOM" "eSideBottom"
rename "NS_SIDE_LEFT" "eSideLeft"

The main renaming was generated with the following python script:
```
import sys
import re
CAMEL_CASE_REGEX = re.compile(r"(^|_|-)([A-Z])([A-Z]+)")
DISPLAY_REGEX = re.compile(r"\bNS_STYLE_DISPLAY_([^M][A-Z_]+)\b")
def to_camel_case(ident):
return re.sub(CAMEL_CASE_REGEX,
lambda m: m.group(2) + m.group(3).lower(), ident)
def constant_to_enum(constant):
return "StyleDisplay::" + to_camel_case(constant) + ("_" if constant == "NONE" else "")
def process_line(line):
return re.sub(DISPLAY_REGEX,
lambda m: constant_to_enum(m.group(1)), line)
lines = []
with open(sys.argv[1], "r") as f:
for line in f:
lines.append(process_line(line))
with open(sys.argv[1], "w") as f:
for line in lines:
f.write(line)
```
And the following shell commands:
```
find . -name '*.cpp' -exec python display.py {} \;
find . -name '*.h' -exec python display.py {} \;
```

By changing signature of those two functions, we make compiler complain about
all their existing uses, so we can find all of them and convert them.
Some of the callsites of Get() with those properties are also converted, but not
all of them. It is fine because if there is any incorrect conversion, compilers
is able to find out now. So they are completely typesafe.
This patch makes methods of FramePropertyTable and FrameProperties to be
simple template wrapper functions. Then it converts all references to
FramePropertyDescriptor to use "void" parameter to simulate the current
unsafe behavior.
SmallValueHolder is used for storing small values like int32_t, float,
which can fit in the size of a pointer directly, and thus no lifetime
management is needed.
AutoTextRun now only needs a DrawTarget instead of an nsRenderingContext, and
similar nsRenderingContext/gfxContext-to-DrawTarget replacements can be
propagated a long way up the call graph. This patch replaces 93 occurrences of
nsRenderingContext and 135 occurrences of gfxContext with DrawTarget; that's
13% of them.
The patch is mostly plumbing changes. A couple of not-entirely-plumbing
changes:
- It adds a comment about the null check in
gfxGlyphExtents::GetTightGlyphExtentsAppUnits().
- A couple of functions simply had an unused gfxContext or nsRenderingContext
parameter removed, e.g. SetLineBreaks().
