Edward Welbourne b0383cbd38 Purge two old time-zone lookup fallbacks
We used to need to consult /etc/timezone for the zone name back when
Debian, up to Jessie, used a copy of the zoneinfo file as
/etc/localtime, instead of a symlink.  Jessie's end of life is this
May, but Thiago reports that its gcc can't build Qt 5.14, so we may as
well remove this fall-back.  Newer versions of Debian use a symlink.

We used to need to consult /etc/sysconfig/clock for this information
back when ancient Red Hat distros copied zoneinfo to /etc/localtime
instead of symlinking, but Thiago believes that's now ancient history.
So, again, remove this old fallback.

QTzTimeZonePrivate::init() was coping with empty and then saving the
system ID if the ID it looked up was empty. Better to have its caller
ensure it's passed the system ID in place of empty. The system ID is
always non-empty, as it falls back to "UTC" if it would otherwise have
been empty.

Thiago Macieira 276fa8383a QLibrary: fix deadlock caused by fix to QTBUG-39642
Commit ae6f73e856 inserted a mutex around
the entire load_sys(). We had reasoed that deadlocks would only occur if
the object creation in instance() recursed into its own instance(),
which was already a bug. But we had forgotten that dlopen()/
LoadLibrary() executes initialization code from the module being loaded,
which could cause a recursion back into the same QPluginLoader or
QLibrary object. This recursion is benign because the module *is* loaded
and dlopen()/LoadLibrary() returns the same handle.

[ChangeLog][QtCore][QLibrary and QPluginLoader] Fixed a deadlock that
would happen if the plugin or library being loaded has load-time
initialization code (C++ global variables) that recursed back into the
same QLibrary or QPluginLoader object.

PS: QLibraryPrivate::loadPlugin() updates pluginState outside a mutex
lock, so pluginState should be made an atomic variable. Once that is
done, we'll only need locking the mutex to update errorString (no
locking before loading).

Alex Trotsenko e0d80167c1 QEventDispatcherWin32: fix posted events delivering
To avoid livelocks, posted events should be delivered when all pending
messages have been processed, and the thread's message queue becomes
empty. Although the logic of the previous patch is correct, it turned
out that determining the moment when the message queue is really empty
is not so simple. It is worth noting that the GetQueueStatus function
sometimes reports unexpected results due to internal filtering and
processing. Indeed, Windows docs say that "the return value from
GetQueueStatus should be considered only a hint as to whether
GetMessage or PeekMessage should be called". Thus, we cannot rely on
GetQueueStatus in unambiguous logic inside the qt_GetMessageHook.

To solve the problem, this patch introduces a guard timer which
guarantees low priority processing for posted events in foreign loop.
The wakeUps flag reset logic has also been changed to provide clearer
synchronization of the Qt internal loop.

Edward Welbourne 333d7e6de4 Clean up QTzTimeZonePrivate::systemTimeZoneId()
The special handling of ":/etc/localtime" should only apply if that's
the exact value of $TZ; the old code would have treated
"/etc/localtime" the same, due to stripping a leading ':' before
checking for it.  We can also test whether to do that stripping using
startsWith().

When reading the content of files, avoid QTextStream's trip via
QString and back to QByteArray by using the QFile's readLine()
directly, or by using readAll().

These message hooks are used to handle ALT+ENTER to enter/exit fullscreen
mode and PRINTSCREEN to take screenshots. Qt is implementing these
functionalities itself so we do not have to register these hooks.

If too many of these hooks are registered, callbacks are no longer called
and Qt's message queue is no longer handling messages. By saving these
hooks we can make sure that more Qt windows at the same time are possible
without getting unresponsive due to too many hooks being registered.

Volker Hilsheimer d934fd7f54 Send MouseMove events without buttons if the press closed the popup
With nested popup widgets, pressing a mouse button on the lower
popup will close the active popup. MouseMove events that are generated
before the button is released again should not have that button
included, as it is likely to result in incorrect state handling in
the widget. This change removes all buttons from the MouseMove event,
which is the second best option.

This is mostly consistent with the behavior when closing a popup and
no other popup remains. The widget underneath will get MouseMove
events without the respective button included.

This change doesn't include a fix for the final release event, which
should ideally also not be delivered to the remaining popup, as it
never got a corresponding press event. Qt has already reset the states
in which it stores which widget received the press event at the time
the release is generated, such as qt_button_down and qt_popup_down.
So we can't separate a release grabbed by a newly opened popup (which
we want) from a release to the popup that became active after closing
(which we don't want).
However, widgets can more easily work around this issue, and the risk
of breaking things by changing the code further becomes too high.

Thiago Macieira 02d595946f QCborValue::fromCbor: Apply a recursion limit to decoding
A simple 16k file can produce deep enough recursion in Qt to cause stack
overflow. So prevent that.

I tested 4096 recursions just fine on my Linux system (8 MB stack), but
decided 1024 was sufficient, as this code will also be run on embedded
systems that could have smaller stacks.

[ChangeLog][QtCore][QCborValue] fromCbor() now limits decoding to at
most 1024 nested maps, arrays, and tags to prevent stack overflows. This
should be sufficient for most uses of CBOR. An API to limit further or
to relax the limit will be provided in 5.15. Meanwhile, if decoding more
is required, QCborStreamReader can be used (note that each level of map
and array allocates memory).

Tor Arne Vestbø 02fa39ed22 macOS: Flush sublayers via separate IOSurface backingstores
Flushing sublayers via QImage copies of the root IOSurface was causing
performance regressions due to the constant allocations of new images
each frame.

We now re-use the QCALayerBackingStore implementation for sublayers,
which gives a dynamic swap-chain.

We're still paying the CPU cost of the copy from the root backingstore
to the layered backingstores, as well as the memory cost, but at least
improves the situation.

We do not try to be smart and paint directly into the sublayers,
as that would leave the root backingstore stale, potentially causing
glitches when views are repositioned. Investigating this is left
for future work.

Robin Burchell 2af04860f6 qtimezoneprivate_tz: Apply a cache over the top of timezone data
Constantly re-reading the timezone information only to be told the exact
same thing is wildly expensive, which can hurt in operations that cause
a lot of QTimeZone creation, for example, V4's DateObject - which
creates them a lot (in DaylightSavingTA).

This performance problem was identified when I noticed that a
QDateTime binding updated once per frame was causing >100% CPU usage
(on a desktop!) thanks to a QtQuickControls 1 Calendar (which has a
number of bindings to the date's properties like getMonth() and so
on).

The newly added tst_QTimeZone::systemTimeZone benchmark gets a ~90%
decrease in instruction count:

--- before
+++ after
 PASS   : tst_QTimeZone::systemTimeZone()
 RESULT : tst_QTimeZone::systemTimeZone():
-     0.024 msecs per iteration (total: 51, iterations: 2048)
+     0.0036 msecs per iteration (total: 59, iterations: 16384)

Also impacted (over in QDateTime) is
tst_QDateTime::setMSecsSinceEpochTz(). The results here are - on the
surface - less impressive (~0.17% drop), however, it isn't even
creating QTimeZone on a hot path to begin with, so a large drop would
have been a surprise.

Added several further benchmarks to cover non-system zones and
traverse transitions.

point. Also adds tests for supression of soft-hyphens in the tight
WrapAnywhere case.

Thiago Macieira ae6f73e856 QLibrary: introduce a mutex to protect non-atomic internals
And make pHnd atomic.

The majority of the variables is updated in QLibraryPrivate::load_sys
and updatePluginState(), which get the mutex protection.
QLibraryPrivate::unload_sys() doesn't need a mutex protection because we
have the refcounting.

[ChangeLog][QtCore][QLibrary & QPluginLoader] Fixed a number of race
conditions caused by having two QLibrary objects pointing to the same
library being operated in different threads.

Thiago Macieira ef92ac5636 QLibrary: stop setting errorString after resolve()
resolve() is technically thread-safe if the library has been loadaed. We
don't promise that, but it's there. More importantly, because
QLibraryPrivate is shared among QPluginLoader and QLibrary that point to
the same file, we can't thread-safely set the error string.

[ChangeLog][Important Behavior Changes] QLibrary::resolve() will no
longer set or clear the error string based on the success of finding the
symbol. The error string will reflect the result of loading the library.

Thiago Macieira f6c1cebe42 QPluginLoader: rework the loading and the caching of instance
There was a race condition in accessing the cached instance factory
member, so rework loadPlugin() to return the cached or newly discovered
instance, with proper, atomic caching. Because I had to change that, I
took the opportunity to fix the QFactoryLoader code that calls
loadPlugin().

Note that QLibraryPrivate::loadPlugin() returns non-nullptr now if the
instance is known, which means the last return in QPluginLoader::load()
will convert to true, not false, if the instance got cached between the
earlier check and the call to loadPlugin(). That's probably what was
intended.

JiDe Zhang 4f370d36ec xcb: Fix logic for minimized state
When _NET_WM_STATE_HIDDEN is not contains in the _NET_WM_STATE
window property, the window should not be considered to be minimized

According to
https://specifications.freedesktop.org/wm-spec/1.3/ar01s05.html
_NET_WM_STATE_HIDDEN should be set by the Window Manager to indicate
that a window would not be visible on the screen if its desktop/viewport
were active and its coordinates were within the screen bounds. The
canonical example is that minimized windows should be in the
_NET_WM_STATE_HIDDEN state. Pagers and similar applications should use
_NET_WM_STATE_HIDDEN instead of WM_STATE to decide whether to display a
window in miniature representations of the windows on a desktop.

For mutter/GNOME Shell, without _NET_WM_STATE_HIDDEN, window manager
will not reply XCB_ICCCM_WM_STATE_ICONIC settings in WM_CHANGE_STATE
client message.
