As of Unicode 5.1, some punctuation marks were mapped to MidLetter and MidNumLet
for better URL and abbreviations handling which caused "hi.there" to be treated
like if it were just a single word;
until we have the Unicode Text Segmentation tailoring mechanism, retain
the old behavior by remapping (some of) those characters back to their old values.

The error and message handlers used by the freetds library were getting
reset to back to the default every time a database was opened. The
Qt TDS SQL driver was calling dbinit() from QTDSDriver::open(). This
had two problems:
1. dbinit() would reset the error handler previously set by a call to
dberrhandle(). A db error would then cause the application to
abort.
2. freetds expects dbinit() and dbexit() to be called symmetrically.
Opening multiple database connections would result in freetds not
cleaning up on application close.
Solved by moving the dbinit() call into the QTDSDriver constructor.

would expect the progress to be 0 after start. Instead it's still
1; the code seems to assume that if the duration is 0, the
progress must be 1 always.
The fix is that if the duration is 0, the direction is checked to
determine whether progress should be 0 (Backward) or 1 (Forward).

obvious the title property is the window title. Unfortunately,
there must be patches in many other modules which depend on this one.
In order to avoid the need to merge them all at the same time,
there is also patch https://codereview.qt-project.org/#change,39001

It does not make sense to add a QLayout to a QSplitter, since the
splitter manages its child widgets in the same manner as a QLayout.
The result of doing so is that the child widgets inside that layout
will lead to the splitter and the layout fighting to position the child
widgets.
QSplitter::addWidget should be used to add widgets directly to the
splitter instead.

The old code is just plain wrong for negative julian days. Replaced
with plain math from The Calendar FAQ [1], which is correct for all

While the conversion code works for up to around JD +/- (2^63/4), we
only use an int for the year in the API, so this patch limits minJd()
and maxJd() to 1 Jan (2^31) BC and 31 Dec (2^31-1) AD, respectively.
Note that while the new conversion code looks like it would be more
expensive than the old, gcc will in fact be able to optimize it to be
slightly faster (probably because x86 hardware implements round to
negative infinity, and so GCC manages to optimize floordiv to a single
instruction, compared to the three instuctions needed for operator/).
In the following test application, run with a release mode Qt and
redirecting stderr to /dev/null, I measured an improvement from
6.81s +/- 0.08s to 6.26s +/- 0.16s user time over five runs on an

There are more opportunities in QtCore and the rest of Qt to make signals
private instead of public. This is a test-dart to see if there is any
reason not to do this.
It would be nice to make QObject::destroyed private, but as it has a
default argument it would be source incompatible to anyone connecting
to the SIGNAL(destroyed()) instead of SIGNAL(destroyed(QObject*)).
Currently the function-pointer-based connect syntax does not accept
a functor (or lambda) with a different number of arguments than the
signal. Olivier says a fix for that might come in 5.1, but for now
the qfiledialog2 test is changed to not use that anymore.
Also, the function pointer for a private signal can not be assigned to
a local variable, so the qmetamethod test is changed to not do so
anymore.

remove() can use non-detaching iterators internally before calling
erase(), which hasn't been exploited so far, so that the detach() in
erase() never actually detached. When using erase() from outside,
you can't do it legally without calling begin() or end() that detach()
before erase() is called.
Now remove() doesn't detach anymore, and detaching in erase() works.
With new tests that fail after changing only the erase() callers
and pass again after fixing erase().

These containers don't make sense and will just result in no action
being taken (all items added will simply be discarded), but it
shouldn't crash due to a division by zero.
Update the documentation to explain the fact.
