Christian Strømme eadf9e542f Android: Don't rely on QDir::homePath() to get the application directory
If the QLoggingRegistry gets called as part of the static initialization
phase, it would call into Android's QStandarPaths implementation, which
assumed that the HOME env. variable was already set. Since the variable
isn't set before main is called, QDir::homePath() returns the root path,
which would be cached and always returned.

With this fix we now call Android's getFilesDir() directly, which will
always return the right path. Since the font locations are also relying
on an environment variable being set, we no longer cache that either.

Tor Arne Vestbø 538b1b5076 Android: Defer initialization of logging rules until qApp construction
On Android, we load the application library, and its dependencies (Qt),
on Android's main thread (thread 0), and then spin up a secondary
thread (thread 1), that we call main() on.

If any QObject is constructed during loading of the application library
or any of Qt's libraries, via static initializers or constructor
functions, we will set QCoreApplicationPrivate::theMainThread to
thread 0, which will confuse Qt later on when it's being run on
thread 1, and will result in a warning during QCoreApplication
construction:

 QApplication was not created in the main() thread

This situation can easily lead to a crash as well.

Unfortunately logging via qDebug/qCDebug and friends will trigger
this too, as they internally use QObject.

Fixing the root cause of this is under investigation, but for now
we will partially revert fa2a653b3b for Android. The effect
is that any qCDebug with a "qt.*" category before qApp construction
will turn into a no-op, like it was before fa2a653b3b.

This patch does not cover the case of a regular qDebug, or a qCDebug
with a non-Qt category. Those will still produce the same symptom,
as before fa2a653b3b.

Tor Arne Vestbø 7d1962cada macOS: Handle update requests via setNeedsDisplay more carefully
Instead of trying to detect situations where we need to send a real
expose event instead of an update request in response to a drawRect
call, we keep track of when we've asked the view to display due to
a requestUpdate call, and only deliver the corresponding drawRect
as an update request if no other code has asked the view to
display.

This should cover all cases of asking the view to display, issued
from our code or from AppKit, such as the view changing its backing
scale factor, or otherwise needing a real expose event.

Joerg Bornemann 6dbf357609 Fix asserts and crashes in QWinEventNotifier activation loop
The backwards iteration was done under the assumption that the only
valid modification of the winEventNotifierList in a slot connected to
activated() would be the removal of the notifier itself. This is wrong.

Instead, iterate forwards, like before 85403d0a, and check the index
against the current list size in every iteration. This ensures that we
do not run out of bounds while the list is modified.

Also, retry the activation loop if the list was modified by a slot
connected to activated(). This ensures that all notifiers with signaled
handles are activated.

Andy Shaw 965bcca6d4 Cocoa: Explicitly hide popup windows when the application is hidden
When the application is hidden then Qt will hide the popup
windows associated with it when it has lost the activation
for the application. However, when it gets to this point it
believes the popup windows to be hidden already due to the
fact that the application itself is hidden. As a result,
when the application is restored it causes a problem with
the still visible popup window as it is taking the input
events without responding to them.

Therefore we need to explicitly hide the windows right before the
application is hidden to ensure that they are actually hidden
correctly.

Konstantin Tokarev d2b2511f88 QNAM should prepend Host header to the header list instead of appending
When original QNetworkRequest is missing "Host" header (which is the most
common case), it is provided automatically from request URL. However,
resulting header is appended to the list, i.e. after all headers specified
by user, which may include a big bunch of cookies.

To the contrary, RFC 7230 suggests: "However, it is good practice to send
header fields that contain control data first, such as Host on requests
and Date on responses, so that implementations can decide when not to
handle a message as early as possible". Many other user agents are
following this suggestion.

actual assembly is already disabled since 8072c36eeb,
but passing the empty assembly file to any random external
assembler could end up producing an empty object file for the

This wasn't an issue as long as the clang compiler only was identified
as g++ within mkspecs, making no_clang_integrated_as a no-op. If
the mkspec actually identifies it as clang, this config can't
be added here.

Andre de la Rocha e211ab76d7 Handle OOM condition in the validation of plugin metadata
A large plugin dll (e.g., one with many MB of debug info) could cause
a 32-bit application to crash when the entire dll file could not fit
within the address space of the process. The code for validating a
plugin library and retrieving metadata from it first tried to map
the entire file in memory, which failed for large files, returning
NULL. In this case, the code tried then to read the entire file via
QFile::readAll(), which deep below caused a bad_alloc exception in
malloc, resulting in the termination of the application. This change
handles the case where the library could not be mapped into memory,
in spite of memory mapping being supported, by reporting the error
and returning false, making the plugin unavailable.

[ChangeLog][QtCore][QPluginLoader] Fixed a bug that would cause the
Qt plugin scanning system to allocate too much memory and possibly
crash the process.

Edward Welbourne 957c1d9abd Use a proper test for absolute path for qmake's location
QFileInfo.isRelative() deems any path starting with a slash to be
absolute; on MS-Win, such paths need a drive specifier (unless they're
UNC), so use IoUtils's more robust test for absolute paths.

Allan Sandfeld Jensen 0ffc39806e Fix cast-function-type gcc 8 warning
Gcc 8 now warns against casting functions taking references to
functions taking pointers:

warning: cast between incompatible function types from ‘QVariant (*)(const int&, const int&, double)’ to
‘QVariant (*)(const void*, const void*, double)’ [-Werror=cast-function-type]

Suppressed by casting over void(*)().

Martin Storsjö bfc96c9c0e Only define QT_FASTCALL on x86_32
The __fastcall calling convention is silently ignored on other
architectures. The GNU attribute regparm is allowed but doesn't
make sense on x86_64. On other architectures, the attribute isn't
supported at all.

This fixes building with clang for MinGW/ARM and ARM64.

Edward Welbourne f9b8ea4b0e Fix QMacTimeZonePrivate::previousTransition() for early after epoch
The native APIs don't support previous transition, only next after a
stipulated date.  The prior code started its search at the epoch; if
used for a time before the first transition after the epoch, this
found no transitions so returned invalid data, when the last
transition before the epoch would have been suitable.  It also wound
through all transitions since the epoch, on its way to the selected
time, which was potentially laborious.

Instead, start a year before the stipulated time; this should get a
transition if the zone uses DST.  If it doesn't, start with the first
known transition and binary-chop our way to one within a year of the
last before the stipulated time; then wind forward one transition at a
time, as before.  The chopping is actually faster than binary: each
time we find a transition after the interval mid-point but early
enough, we move the early end of our interval to the transition, which
is later than the old interval's middle.  Using halving, starting with
a vast interval, should thus only incur modest cost, while ensuring we
give up early when no transition data is available at all or the
zone's first transition ever was after the stipulated time.
