fa2a653b3b Initialize QLoggingRegistry rules on first use
Allows categorized logging before QCoreApplication has been created,
which otherwise would silently fail to output anything because the
category would never be enabled, despite QT_LOGGING_RULES being set.

4be50ecafd QTemporaryFile: fix issues with removing a file twice
The assertion in isUnnamedFile() we had was incorrect after the file was
removed, since we cleared the name and possibly reset back to the
template. Since ~QTemporaryFile() calls remove(), this was easy to
trigger if you attempted to remove the temp file and leave
QTemporaryFile like that.

Take this opportunity to add to the docs of setAutoRemove() explaining
the possibility of unnamed files.

b8e352ad37 Add functions for fast bulk conversion of qfloat16
Both ARM and x86 can convert fp16 much faster in bulk than one at a
time. This also enables hardware accelerated conversion on x86, when
F16C isn't unconditionally available at compile time.

This code is implemented in C to ensure that there's no leakage of
inline symbols from the .obj file that was compiled by Visual Studio
with AVX support. Unfortunately, simd.prf uses $(CXX) instead of $(CC)
for all its sources, which means the file gets interpreted as C++ by
g++, clang++ and icpc. Those compilers at least don't leak any symbols.

ce08318a46 Add QThreadPool autotest to detect stale threads after tryTake
This test makes sure that we do not introduce a regression where the
threads exited the inner loop over the queue before the queue was
empty. This was triggered by calling tryTake at least maxThreadCount
times, which left the same number of null pointers in the queue
and caused the inner loop to exit too soon for all the threads.

285596ee19 Special-case parsing of Zulu time-zone in date-times
When parsing a date-time's zone, a stray Z denotes UTC (a.k.a. Zulu
time), despite not being a valid name for the zone.  Clients parsing
such date strings had to treat the Z as a literal, rather than a
zone-ID, but then they got back a LocalTime instead of the UTC the
string actually described.  So teach QTimeZoneParser to handle this
special case and adapt an existing test (that used a time ending in Z,
but had to treat it as a local time) to check this works.

[ChangeLog][QtCore][QDateTime] When parsing a time-zone, "Z" is now
recognized as an alias for UTC.

This allows us to make sure that the PID we read is from the same boot

[ChangeLog][QtCore][QLockFile] QLockFile can now properly conclude that

the templated Sseq requirements because it would require moving the
implementation details to the public API. And we don't implement the

cfad4e298f QRandomGenerator: add securelySeeded(), to ensure appropriate seeding
Since we don't document how many bytes one needs (it's 2496), it's
difficult for the caller to provide just enough data in the seed
sequence. Moreover, since std::mt19937 doesn't make it easy to provide
the ideal size either, we can't actually write code that operates
optimally given a quint32 range either -- we only provide it via
std::seed_seq, which is inefficient.

However, we can do it internally by passing QRandomGenerator to the
std::mersenne_twister_engine constructor, as it's designed to work.

is the haystack (same problem memcpy() has). Compare that to

which can clearly be read in English as a subject-verb-object sentence.

c90d9f95d2 QRandomGenerator: improve floating-point random generation
The previous version was good, just not optimal. Because the input was
an unsigned 64-bit number, compilers needed to generate extra code to
deal with HW instructions that only convert 64-bit signed input. And
that was useless because a double uniformly distributed from 0 to 1 can
only have 53 bits of randomness.

The previous implementation did exactly what the Microsoft libstdc++ and
libc++ implementations do. In my opinion, those implementations have an
imperfect distribution, which is corrected in this commit. In those, all
random input bigger than 0x20000000000000 has a different frequency
compared to input below that mark. For example, both 0x20000000000000
and 0x20000000000001 produce the same result (4.8828125e-4).

What's more, for the libc++ and MSVC implementations, input between
0xfffffffffffff001 and 0xffffffffffffffff results in 1.0 (probability 1
in 2⁵³), even though the Standard is very clear that the result should
be strictly less than 1. GCC 7's libstdc++ doesn't have this issue,
whereas the versions before would enter an infinite loop.

f62768d046 QUrl: re-fix the setPath("//path") case leading to scheme://path
Commits aba336c2b4 (in Qt 5.2) and
aba336c2b4 (in 5.6) both tried to deal
with this problem, with different levels of success. This is the third
attempt (and hopefully the charm).

Instead of modifying the path that the user provides, go straight ahead
and declare it invalid. This is supported by RFC 3986, which declares
this expansion impossible:

   relative-part = "//" authority path-abempty
                 / path-absolute
                 / path-noscheme
                 / path-empty
   path-abempty  = *( "/" segment )
   path-absolute = "/" [ segment-nz *( "/" segment ) ]
   path-noscheme = segment-nz-nc *( "/" segment )

The "path-abempty" and "path-noscheme" cases are the two issues we
already handle. This commit adds the third one: path-absolute, which
requires that the first segment of the path be of non-zero length.

That is, it is now possible again to have http://example.com//path
constructed piece-wise, without it producing http://example.com/path.
Additionally, it catches the case of http://example.com//path parsed
from full URL then followed by setAuthority("").

3b61cd6ad7 QStringView: De-inline the length calculation so we can use SSE2
Performance is more important in this case than the theoretical benefit
of constexpr. This commit implements the SSE2 search for 16-bit null and
it might be possible to implement the equivalent for AArch64
(investigation required). It also adds a fallback to wcslen() for
systems where wchar_t is short (non-x86 Windows or 32-bit x86 build with
-no-sse2).

We can re-add the constexpr loop once the C++ language has a way of
overloading constexpr and non-constexpr. GCC has a non-standard way to
do that with __builtin_constant_p, which is also implemented in this
commit, but note that the inline function is still not constexpr.

d044b0b1e3 Remove timer checks from testQuitLock
This test sets up two timers:
	- a 100ms recurring timer
	- a series of 10 200ms single-shot timers.

After quitLock lets exec() return it then uses a signal
spy to check if the 100ms timer fired at least 17/20
of the times it should.

However there is no guarantee that the 100ms timer
will fire more often than the 200ms timer. If the
native timer callbacks happen at 500ms intervals then
Qt will fire both timers (once) at that interval.

In practice this seems to happen on macOS CI under
system load and/or with the test app napping.

The primary goal for the test is to verify that exec()
returns when it should; we can remove the timer signal
spy.

Remove testQuitLock from BLACKLIST.

Timely timer:

  524429311.389913 runLoopTimerCallback
  524429311.389979 200ms fire

5d2240718c Autotest: fix blacklisted test about position on non-regular files
On BSD systems (tested on macOS and FreeBSD), you *can* lseek(2) or
ftell(3) on a pipe and get its current position. But QFile will not get
the position when the file is sequential, so we need to return 0.

Technically speaking, we ought to do the same for block devices, but if
you're redirecting stdin, stdout or stderr in the unit test to or from a
block device, you deserve the extra work to add that yourself to the
test.

6504bc6bbc QFileInfo: harmonize QFileInfo() and QFileInfo("")
If a QFileInfo was constructed with an empty path, which could happen
with QFileInfo(QFile()) or via QDir, etc., then it would issue system
calls to empty paths and could even produce warnings. This commit makes
am empty path name be the same as a default-constructed QFileInfo and
corrects the use if 0 for ownerId and groupId to match the
documentation.

[ChangeLog][Important Behavior Changes] QFileInfo on empty strings now
behaves like the default-constructed QFileInfo. Notably, path() will now
be the empty string too, instead of ".", which means absoluteFilePath()
is no longer the current working directory.

6c3a3d498a Filesystem: Use "birth time" to avoid confusion with Unix ctime
The Unix stat fields "st_ctime" and "st_ctim" mean "change time", the
last time that the file/inode status fields were changed. It does not
mean "creation time". So this commit splits all of the internal API to
"birth" and "metadata change" instead of "creation" to avoid the
conflict.

261c6713bd Introduce QFileInfo::birthTime and metadataChangeTime
[ChangeLog][QtCore][QFileInfo] Deprecated created() because it could
return one of three different file times depending on the OS and
filesystem type, without the ability to determine which one is which. It
is replaced by metadataChangeTime() and birthTime().

[ChangeLog][QtCore][QFileInfo] Added QFileInfo::metadataChangeTime(),
which returns the time the file's metadata was last changed, if it is
known, and falling back to the same value as lastModified() otherwise.
On Unix systems, this corresponds to the file's ctime.

[ChangeLog][QtCore][QFileInfo] Added QFileInfo::birthTime(), which
returns the file's birth time if it is known, an invalid QDateTime
otherwise. This function is supported on Windows and on some Unix
systems.

a9c111ed8c Clean-up in QDateTime's parsing of ISODate{,WithMs}
Actually check that there's a T where ISO 8601 wants it (instead of
just skipping over whatever's there), with something after it; move
some declarations later; add some comments; and use the QStringRef API
more cleanly (so that it's easier to see what's going on).  Simplify a
loop condition to avoid the need for a post-loop fix-up.

This incidentally prevents an assertion failure (which brought the
mess to my attention) parsing a short string as an ISO date-time; if
there's a T with nothing after it, we won't try to read at index -1 in
the following text.  (The actual fail seen had a Z where the T should
have been, with nothing after it.)

Add tests for invalid ISOdate cases that triggered the assertion.

[ChangeLog][QtCore] Added qEnvironmentVariable, which returns the value

same as QFile::decodeName, which means NFC/NFD conversion on Apple OSes.

I opted not to #include <qfile.h> from qglobal.cpp to implement that
QFile::decodeName functionality, so qglobal.cpp doesn't depend on
corelib/io and to avoid possible recursions.
