1ad424aed5 QLocal{Socket,Server}: extend the test coverage for property bindings
The pre-existing test for QLocalServer was testing only a minor subset
of cases, so replace it with the call to
QTestPrivate::testReadWritePropertyBasics.

The test for QLocalSocket's bindable properties was missing, so add
it.

The new tests didn't reveal any problems.

1c6bf3e09e Port from container::count() and length() to size() - V5
This is a semantic patch using ClangTidyTransformator as in
qtbase/df9d882d41b741fef7c5beeddb0abe9d904443d8, but extended to
handle typedefs and accesses through pointers, too:

    const std::string o = "object";

    auto hasTypeIgnoringPointer = [](auto type) { return anyOf(hasType(type), hasType(pointsTo(type))); };

    auto derivedFromAnyOfClasses = [&](ArrayRef<StringRef> classes) {
        auto exprOfDeclaredType = [&](auto decl) {
            return expr(hasTypeIgnoringPointer(hasUnqualifiedDesugaredType(recordType(hasDeclaration(decl))))).bind(o);
        };
        return exprOfDeclaredType(cxxRecordDecl(isSameOrDerivedFrom(hasAnyName(classes))));
    };

    auto renameMethod = [&] (ArrayRef<StringRef> classes,
                            StringRef from, StringRef to) {
        return makeRule(cxxMemberCallExpr(on(derivedFromAnyOfClasses(classes)),
                            callee(cxxMethodDecl(hasName(from), parameterCountIs(0)))),
                        changeTo(cat(access(o, cat(to)), "()")),
                        cat("use '", to, "' instead of '", from, "'"));
    };

    renameMethod(<classes>, "count", "size");
    renameMethod(<classes>, "length", "size");

except that the on() matcher has been replaced by one that doesn't

4e695eece7 QWindowsPipeWriter: do not clear the buffer in thread pool callback
In a blocking application, receiving the results of write operations
must be synchronized with the waitFor...() functions. But, clearing
the buffer in another thread can cause the code

  localsocket.write(...);
  QVERIFY(localsocket.bytesToWrite() > 0);

to fail unexpectedly, if the socket has been disconnected between
the calls.

So, defer resetting the buffer until checkForWrite() is called.

5d68858ba7 QLocalSocket/Win: fix waitFor...() functions for write-only socket
There were several issues with the socket state checking when the pipe
reader is not running:

  - the number of object handles in the WaitForMultipleObjectsEx()
    call might have been zero;
  - a call to the waitForDisconnected(-1) might have hung;
  - we did not perform a loop iteration for the waitFor...(0) calls,
    so disconnect detection was unreliable.

These issues are related to the same code, so they don't seem to be
addressable separately.

f265c87e01 Allow QWindowsPipe{Reader|Writer} to work with foreign event loops, take 2
When a foreign event loop that does not enter an alertable wait state
is running (which is also the case when a native dialog window is
modal), pipe handlers would freeze temporarily due to their APC
callbacks not being invoked.

We address this problem by moving the I/O callbacks to the Windows
thread pool, and only posting completion events to the main loop
from there. That makes the actual I/O completely independent from
any main loop, while the signal delivery works also with foreign
loops (because Qt event delivery uses Windows messages, which foreign
loops typically handle correctly).

As a nice side effect, performance (and in particular scalability)
is improved.

Several other approaches have been tried:
1) Using QWinEventNotifier was about a quarter slower and scaled much
   worse. Additionally, it also required a rather egregious hack to
   handle the (pathological) case of a single thread talking to both
   ends of a QLocalSocket synchronously.
2) Queuing APCs from the thread pool to the main thread and also
   posting wake-up events to its event loop, and handling I/O on the
   main thread; this performed roughly like this solution, but scaled
   half as well, and the separate wake-up path was still deemed hacky.
3) Only posting wake-up events to the main thread from the thread pool,
   and still handling I/O on the main thread; this still performed
   comparably to 2), and the pathological case was not handled at all.
4) Using this approach for reads and that of 3) for writes was slightly
   faster with big amounts of data, but scaled slightly worse, and the
   diverging implementations were deemed not desirable.

ad2da2d27a Remove the qmake project files
Remove the qmake project files for most of Qt.

Leave the qmake project files for examples, because we still test those
in the CI to ensure qmake does not regress.

Also leave the qmake project files for utils and other minor parts that
lack CMake project files.

This reverts commit ee122077b0.

Reason for revert: This causes QProcess::readAll() to sometimes

ee122077b0 Allow QWindowsPipe{Reader,Writer} to work with foreign event loops
When a foreign event loop that does not enter an alertable wait state
is running (which is also the case when a native dialog window is
modal), pipe handlers would freeze temporarily due to their APC
callbacks not being invoked.

We address this problem by moving the I/O callbacks to the Windows
thread pool, and only posting completion events to the main loop
from there. That makes the actual I/O completely independent from
any main loop, while the signal delivery works also with foreign
loops (because Qt event delivery uses Windows messages, which foreign
loops typically handle correctly).

As a nice side effect, performance (and in particular scalability)
is improved.

Several other approaches have been tried:
1) Using QWinEventNotifier was about a quarter slower and scaled much
   worse. Additionally, it also required a rather egregious hack to
   handle the (pathological) case of a single thread talking to both
   ends of a QLocalSocket synchronously.
2) Queuing APCs from the thread pool to the main thread and also
   posting wake-up events to its event loop, and handling I/O on the
   main thread; this performed roughly like this solution , but scaled
   half as well, and the separate wake-up path was still deemed hacky.
3) Only posting wake-up events to the main thread from the thread pool,
   and still handling I/O on the main thread; this still performed
   comparably to 2), and the pathological case was not handled at all.
4) Using this approach for reads and that of 3) for writes was slightly
   faster with big amounts of data, but scaled slightly worse, and the
   diverging implementations were deemed not desirable.

039d3fe4e8 Android: blacklist a list of failing tests for android
We want to re-enable Android tests in QTQAINFRA-3867. However,
many tests are failing already preventing that from happening.
QTBUG-87025 is currently keeping track (links) to all of those
failing tests.

The current proposal is to hide those failing tests, and enable
Android test running in COIN for other tests. After, that try
to fix them one by one, and at the same time we can make sure
no more failing tests go unnoticed.

53b4556332 QLocalSocket/Win: prevent writing to broken pipe
When a peer closes the connection, the device remains opened for reading
purposes. However, we should disable writing on disconnected socket.
Otherwise, if the user issues a write() call, a new pipe writer object
will be created and the write call occurs with invalid handle value.
