ccd4da392c Do not force a content-type on POST request with no content
While a POST request with no body may be a pointless thing it does
happen on many websites. Currently this causes QtNetwork to print a
warning to the console and set an invalid content-type. This patch
allows the content-type to be absent when content is.

b00d4475aa Fix broken resource cleanup in QOpenGLWidget
The context has to be made current. Otherwise we may fail to clean up or,
what's worse, we may delete FBOs and textures in some random context.

The latter was visible with ANGLE in the qopenglwidget example. When having
two QOpenGLWidget instances, the context for the second happened to be the
current one when destroying the first. This is now avoided by making sure the
correct context is current when deleting the FBOs.

f1aafb595b Make configure fail on invalid (-no)-feature options
configure script has been silently accepting whatever flags that begin
with "-feature-" even if the feature name does not exist at all.

Since the script validates many other flags, this behavior can make
users believe flags they supply is valid when it isn't.
Besides, this option is currently not protected against typo in any way.

This commit verifies those flags against content of
"qtbase/src/corelib/global/qfeatures.txt" and fails if supplied
flag is not a valid feature name.

a4428d480b Fix for current_fbo getting out of sync in QtOpenGL
When using QGLWidget in combination with QOpenGLFramebufferObject from
QtGui, instead of QGLFramebufferObject from QtOpenGL, the current_fbo
variable doesn't get updated when framebuffer object bindings change.

To ensure that the QGLWidget correctly releases the currently bound
framebuffer object when using a QPainter, we keep track of whether
QOpenGLFramebufferObject has modified the current FBO binding, and if
that's the case we need to read the OpenGL state directly instead of
relying on a cached value.

459a32e39b mkspec macx-ios-clang: ensure SDK version is valid
Ensure the sdk is of recent enough version since:
1. we build Qt with the latest sdk version, so the app needs
    to do the same to avoid compatibility problems e.g when linking.
2. using a launch screen to support iphone6 depends on sdk 8
3. Apple requires apps that are pushed to appstore to use the
    latest version of the sdk.

Ideally we should store the sdk version used to build Qt, and
require that apps use the same version or newer. But this patch
will do until that is in place.

check for libssl.dylib, libcrypto.dylib in the system paths:
The system's /usr/lib/libssl.dylib, /usr/lib/libcrypto.dylib
will still be picked up as a fallback in the alternative search
paths, but only after .app/Contents/Frameworks have been inspected.

[ChangeLog][QtNetwork][QSsl] On OS X and iOS, openssl dylib's are
picked up from the 'Frameworks' directory of the app bundle.

719a6fd50d iOS: Allow virtual keyboard to be hidden by QInputMethod::hide()
Calling the function has the same effect as dismissing the keyboard using
the native keyboard dismiss button or the hide-keyboard gesture, and will
result in the QIOSTextInputResponder losing first-responder status and
the current focus object being cleared.

QtWidgets and other parts of Qt will try to hide the keyboard during
focus changes between widgets, which we already take care of when the
focus object changes, so we detect the situation and ignore it, by
requiring that the current focus object matches the one we've brought
up the text responder for.

Showing the virtual keyboard is still a no-op, as there is no way to
show the virtual keyboard without a focus-object.

are various reasons why that is possible (memory pressure, item gets

2) the user must always draw the same content from within paint(),
unless update() was called before that call to paint().

13401116cc Remove incorrect read from QSslSocket::readData()
QIODevice makes readData() call only when its read buffer is empty.
Also data argument points to the user or reserved read buffer area.
So, no need in data transfer from read buffer at this point at all.

c493546a0a Merge TextFormat attributes for identical ranges in QInputMethodEvents
IBus can hand us multiple attributes for different formatting properties
of the same text range for events. The IBus input method plugin used to
convert these straight into multiple QInputMethodEvent::Attributes, each
with their own QTextCharFormat instance.

According to the QInputMethodEvent documentation, behavior with multiple
TextFormat attributes for the same text range is undefined. In at least
one known user, KDE's Kate text editor, it causes invisible text for
pre-edit text events as the QTextCharFormats are applied in turn with
partially default-constructed foreground/background brushes:

https://bugs.kde.org/show_bug.cgi?id=339467

This patch makes an effort to merge formatting information for identical
text ranges into a single QTextCharFomat, while otherwise preserving
existing behavior (attribute order is unchanged and attributes deseria-
lized from D-Bus as having invalid QTextFormats remain untouched).

No attempt is made to cope with overlapping text ranges. Segmenting into
smaller ranges and merging for the overlaps would be conceivable, but
until a case of an input method creating events with overlapping ranges
is known seems not worth the effort.

It's worth noting that the IBus input method plugin for Qt 4 also
attempts to merge formatting information into a single QTextCharFormat,
but with a distinct implementation from this one.
