4be7cd09d6 xcode generator: don't modify or copy QMAKE_INFO_PLIST
If the project has a custom Info.plist assigned to
QMAKE_INFO_PLIST, we should leave it as-is without
scanning and replacing contents inside it. Since we
always copy the file to the build folder at qmake
time, any later attempts to modify the source file
will not have any effect.

A better solution is to just reference the custom
plist directly from the Xcode, without modifying it.

This change will also stop unixmake2 from assigning the
default plist to QMAKE_INFO_PLIST, since we need to
know in the xcode generator if the variable was set in
the project or not.

bf50bf737b iOS: don't report negative selection ranges for backspace
Qt sometimes report that the selection anchor is placed before
the cursor when querying it for current selection. We need to
accomodate for this when reporting current selection back to
iOS, since it expects the range to always be positive.

When pressing backspace, iOS will select the letter that should be
deleted, and then call "deleteBackwards". If holding down backspace
for a while, it will start selecting whole words instead.
Since we reported negative ranges during this process, it caused
artifacts and stray letters to be drawn.

5283a6c87b Disable hash seeding for bootstrapped tools
Any bootstrapped tool is a development tool, by definition. So the
effects of seeding the hash with a random number can cause the same
source input to produce different binary results, which can throw some
caching tools into disarray (like the Open Build System).

There should be minimal fall out from the reduced protection against
DoS. Since those are only development tools, "specially crafted" input
implies the developer is DoS'ing him/herself.

Note: the change to qhash.cpp applies to moc and rcc, which are always
bootstrapped.

0ab9188ad7 Rename some QTextEngine members to reflect their meaning
formats() -> formatCollection()
additionalFormats -> formats

QTextEngine has three different code paths: in context of QTextDocument,
additionalFormats are currently _additional_ formats;
though in QTextLayout, they are the only formats in use;
and the QRawFont-related path shares the QTextLayout's behavior.

This is a preparation step to consolidating these three into a single one.

1b031630de fix too aggressive installation of helper libraries
of course all helper libraries are built statically, so the criterion is
not useful. what is interesting is whether the whole qt configuration is
static, as that determines what will happen with the helper library when

First and foremost, the STL-style iterators don't do this. Those don't
provide a guarantee that the container won't get shared again while the
iterator is active.

Second, there's no protection against a second mutable iterator being
created and resetting the sharable flag back to true.

[ChangeLog][Important behavior changes] The mutable Java-style iterators
like QListMutableIterator and QHashMutableIterator no longer set the
parent container to unsharable mode. If you create a copy of the
container being iterated on after the iterator, any changes done with
the iterator might affect the copy too.

1aede2d7fc QPainter on QBitmap: make setBrush(NoBrush) work as expected.
It had no effect because of an explicit check for NoBrush.
However the default in QBitmap is (unfortunately) QBrush(color0), rather
than NoBrush, so the brush must be updated when calling setBrush(NoBrush).

I suppose the real issue is that lastBrush is default-constructed in
QRasterPaintEngine, rather than starting with the brush from QPainter,
which is QBrush(color0) for the case of the bitmap. But no reason to
special case NoBrush here anyway.

that works on both OS X and iOS.
So we can therefore remove the one from the cocoa port.

6388163df8 qmacmime: rename and move QMacPasteboardMimePlainText to the cocoa plugin
com.apple.traditional-mac-plain-text is not in use on iOS
according to Apples UTType reference. So we enable it only
for OS X by moving it into the cocoa port.

The order in which we instanciate convertors matters when
the application is reading data from the pasteboard.
But since QMacPasteboardMimePlainText should come before the
other "text/plain" convertors on OS X, moving it to the cocoa
port is safe as those convertors are instanciated after
those in qmacmime.

72558e810d Avoid setting unnecessary parameters in QOpenGLWidget
QOpenGLFramebufferObject sets the texture parameters already, do
not set them again. Especially not GL_REPEAT, which is wrong and
breaks on devices that do not support REPEAT on NPOT textures.
What QOpenGLFramebufferObject does is just fine (it sets NEAREST/
NEAREST and CLAMP_TO_EDGE).

This is important for WebEngine where the QWidget-based web view
is using QOpenGLWidget.

ca15825ed4 Add viewport transform to QMatrix4x4
This allows to easily create a matrix that performs the transformation
used by OpenGL fixed function to go from normalized device coordinates
to window coordinates.

This comes in useful if you need to perform the NDC->window coordinate
conversion inside a shader.

71fb3633e8 Unify all mid() functions in QtBase.
Up to now, Qt had at least 3 different implementations of the mid().
Only QString::mid implementation was not crashing on edge cases and
was protected against overflows, therefore I picked that one as the
base implementation, even if it has weird semantics for an invalid
input.

As a side effect QVector::mid was slightly optimized to not detach in
all cases (which follows current QList behavior). Documentation of
QVector::mid and QList::mid was updated to not mention "copy of data"
which could suggest that the mid() result is detached.

QStringRef::mid was fixed and now it follows general Qt behavior, by
returning a null value for a null input.
