af3c7d35b6 Fix qmake's use of Q_ASSERT with side-effects.
The nice side-effect of having Q_ASSERT use the condition twice is
that we break code that has side-effects.

c0791b86ab allow the unix generator to run in windows host mode
this is a complete bastardization of the concept and breaks the (unused)
debugging feature to create proper unix makefiles under windows, but
apparently it permits cross-compiling unix targets under windows.

2dd6f1467f Allow qmake to find features when using mkspecs in nested dirs
Commit 8e5eb1bddc introduced the assumtion that mkspecs are
immediately below the mkspecs directory itself. This is not true for
e.g. unsupported/blackberry-armv7le-qcc.

This commit restores qmake's ability to find the "root" of the mkspecs
collection no matter how deeply the actual mkspecs are nested.

aed6eaa5b2 QT_RAW_INSTALL_FOO => QT_INSTALL_FOO/raw
this makes the "sysrootable" properties more magic, with the raw
versions being omitted from the qmake -query output and automatically
falling back to the "cooked" variant if there is no sysroot set.

this makes the "normal" qmake -query less noisy. this will become even
more obvious when i add more "overloads" of the properties.

703ef4f79e make QMakeProject's copy c'tor actually behave like one
instead of initializing base_vars with the original's vars, initialize
vars itself. this has two consequences:
- there is no need to call read(0) to initialize vars
- one cannot usefully call the complex read() anymore, as that would
  re-initialize vars from base_vars

this is much closer to an actual copy than the previous "seeding with
existing project".

load()/include() with a target namespace would inherit the current
context. however, if you source a project with all bells and whistles,
this makes completely no sense and may be actually counterproductive.

infile()/$$fromfile() would have interited only the functions from the

don't inject the build pass specific variables into the project even
before evaluating the .spec file and the .qmake.cache. they are not
supposed to base configuration on that - feature files should do that
later.

the immediate advantage of this is that base_vars is never manipulated
upfront any more, which allows for cleaner setup paths. also, we can do
more caching of the spec+cache contents.

78faefdbb1 Implement missing replacements when installing .pc files for win32
This implements replacements for win32 makefile generators similar
to the replacement functionality in unix makefile generators.

To enable Makefile code generation for replacements in win32 makefile
generators, you must set QMAKE_STREAM_EDITOR to e.g. sed.

When building for win32, sed is normally only available in the
mingw/msys build environment and when cross compiling on unix.
In these cases QMAKE_STREAM_EDITOR is set to sed in qmake.conf.

For other win32 build environments QMAKE_STREAM_EDITOR is not set
in qmake.conf and the replacements Makefile code is not generated.

65b42dd4c8 look for mkspecs in the project root, not next to every project
qmake would look for mkspecs/ in the directory containing the current
project file. this makes completely no sense with recursive projects:
a) nobody would make per-project specs and b) specs meant to be global
would not be found.

consequently, we look for a project root when starting qmake and use
only that directory.
if .qmake.cache is found/set, we assume that to be the project root.
otherwise, we search for mkspecs/ the same way we search for the cache -
just to up until we find one or hit the root. if we are shadow-building,
search the build dir as well.

8397a44bed QByteArray: deprecate QT_NO_CAST_FROM_BYTEARRAY-protected operators
The QByteArray::operator const {char,void}*() implicit
conversions are a source of subtle bugs, so they right-
fully can be disabled with QT_NO_CAST_FROM_BYTEARRAY.

  const char *d = qstring.toLatin1(); // implicit conversion
  while ( d ) // oops: d points to freed memory
     // ...

But almost no-one ever enabled this macros in the wild
and many were bitten by these implicit conversions, so
this patch deprecates them.

I would have liked to remove them completely, but there
are just too many occurrences even in Qt itself to hope
to find all conditionally-compiled code that uses these.

Also fixes all code that needs to compile under
QT_NO_DEPRECATED (in qmake/, src/tools/).

I984706452db7d0841620a0f64e179906123f3849 separately
deals with the bulk of changes in src/ and examples/.

Depends on I5ea1ad3c96d9e64167be53c0c418c7b7dba51f68.

219a688ac1 Add TARGET_VERSION_EXT to pkgConfiglibName
The libName that is used in pkgConfig files should include the

This is needed because in Win32MakefileGenerator::fixTargetExt(),
the TARGET_VERSION_EXT is added to the library name.

In Win32MakefileGenerator::processVars(), if TARGET_VERSION_EXT is empty,
it is set to VER_MAJ.

On platforms != Windows, TARGET_VERSION_EXT does not seem to be used.

We probably got away with this so far because pkgconfig files generation
for win32 was just added in 4.8 and nobody uses them yet, and because on
platforms != windows the TARGET_VERSION_EXT is not used.

8583bc914a Fixed resolution of QMAKESPEC on Windows.
base_vars["QMAKESPEC_ORIGINAL"] is not guaranteed to be set the first
time resolveSpec is called, since an include() can wipe it out.  Change
it so that resolveSpec is called repeatedly until some
QMAKESPEC_ORIGINAL is set.

The code which attempted to remove all of the path up to the last / was
incorrect and must have been dead code (or its wrongness didn't matter)
until now.

It was the result of miscoordination between Andreas Holzammer and me,
duplicating the functional change of commit

This reverts commit 8b7a9b4898.

7bbe79fe5f Drop file-engine abstraction from public API
This abstraction imposed serious performance penalties and is being
dropped from the public API.

In particular, by allowing file names to be arbitrarily hijacked by
different file engines, and requiring engines to be instantiated in
order to decide, it imposed unnecessary overhead on all file operations.

Another flaw in the design with direct impact on performance is how
engines have no way to provide (or retain) additional information
obtained when querying the filesystem. In many places this has meant
repeated operations on the file system, where useful information is
immediately discarded to be queried again subsequently.

For Qt 4.8 a major refactoring of the code base took place to allow
bypassing the file-engine abstraction in select places, with
considerable performance gains observed. In Qt 5 it is expected we'll be
able to take this further, reaping even more benefits, but the
abstraction has to go.

[Dropping this now does not preclude that virtual file systems make an
appearance in Qt at a later point in Qt 5's lifecycle. Hopefully with a
new and improved abstraction.]

Forward declarations for QFileExtension(Result) were dropped, as the
classes were never used or defined.

Tests using "internalized" classes will only fully run on developer
builds. QFSFileEngine was removed altogether from exception safety test,
as it isn't its intent to test internal API.
