Some environments may be broken beyond our capabilities to detect, or
maybe the user is just insane and doesn't want to build my nice shiny
cairo-trace. Whatever, give them the option to choose:
$ ./configure --disable-trace
|
|
The -Wstrict-prototypes and -Wmissing-prototypes warnings
weren't actually in use due to typos.
|
|
Sun Studio 12 doesn't like it when we mix our
enum values and types. We do that a lot on purpose
so the warnings from compiles were very verbose.
|
|
We don't actually check that -Wno-attribute does what
we think it does. On clang it doesn't since it happily
seems to recognize but ignore the attribute.
This patch factors out a silent version of CAIRO_CC_TRY_FLAG
which accepts an optional program argument and actually tests
that the compiler doesn't produce any warning messages. It
is then used to check that -Wno-attribute doesn't complain
when the __warn_unused_result__ attribute is applied to
void functions or variables.
|
|
Some other compilers such as clang and icc support the
__builtin_return_address() intrinsic as well, so we don't
need to check for __GNUC__ >= 3 only.
|
|
The fenv.h stuff was checked twice.

Originally written by Vladimir Vukicevic to investigate using Skia for
Mozilla, it provides a nice integration with a rather interesting code
base. By hooking Skia underneath Cairo it allows us to directly compare
code paths... which is interesting.

Use -Wcast-align simply generates too much noise due to false-positive
reports when casting pixels to uint32_t.
|
|
A very simple surface that produces a hierarchical DAG in a simple XML
format. It is intended to be used whilst debugging, for example with the
automatic regression finding tools of cairo-sphinx, and with test suites
that just want to verify that their code made a particular Cairo call.
|
|
Add a new surface type that multiplies it input onto several output
surfaces. The only limitation is that it requires a master surface that is
used whenever we need to query surface options, such as font options and
extents.
|
|
-Wbad-function-cast in particular. Triggers quite a few warnings where we
have explicitly cast to an integer.
|
|
That limitation was lifted long ago after twin face was introduced.
|
|
|
|
Workaround for my arm toolchain which succeeds in linking the configure
program, only to complain when linking a program (such as cairo-perf)
against libcairo.so. Annoying.
|
|
Remove the intermediate C program that was a nuisance whilst
cross-compiling and replace it with a simple shell script that is just a
combination of cat + sed.

Use the DRM interface to h/w accelerate composition on image surfaces.
The purpose of the backend is simply to explore what such a hardware
interface might look like and what benefits we might expect. The
use case that might justify writing such custom backends are embedded
devices running a drm compositor like wayland - which would, for example,
allow one to write applications that seamlessly integrated accelerated,
dynamic, high quality 2D graphics using Cairo with advanced interaction
(e.g. smooth animations in the UI) driven by a clutter framework...
In this first step we introduce the fundamental wrapping of GEM for intel
and radeon chipsets, and, for comparison, gallium. No acceleration, all
we do is use buffer objects (that is use the kernel memory manager) to
allocate images and simply use the fallback mechanism. This provides a
suitable base to start writing chip specific drivers.

Based on the work by Øyvind Kolås and Pierre Tardy -- many thanks to
Pierre for pushing this backend for inclusion as well as testing and
reviewing my initial patch. And many more thanks to pippin for writing the
backend in the first place!
Hacked and chopped by myself into a suitable basis for a backend. Quite a
few issues remain open, but would seem to be ready for testing on suitable
hardware.

The meta-surface is a vital tool to record a trace of drawing commands
in-memory. As such it is used throughout cairo.
The value of such a surface is immediately obvious and should be
applicable for many applications. The first such case is by
cairo-test-trace which wants to record the entire graph of drawing commands
that affect a surface in the event of a failure.
|
|
Enforce that each test must render within 60 seconds or be considered to
have hit an infinite loop and be reported as a CRASH. The timeout value is
adjustable via CAIRO_TEST_TIMEOUT -- a value of 0 will disable.
|
|
Evaulate the integer sizes during configure to find one of the exact same
size as a void* to use in the conversion of the atomic ptr cmpxchg to an
atomic int cmpxchg.

Solaris 9 confuses shave, resulting in an empty variable.
This patch papers over the resulting build failure from
the test shell built-in being called with an empty argument
which was unquoted.
|
|
This adds a configure check for fenv.h and makes
invalid-matrix.c check for it with HAVE_FENV_H instead
of HAVE_FEDISABLEEXCEPT -- turns out Solaris doesn't
have fedisableexcept(), but it does have feclearexcept().
The same issue appears on OSX and was fixed in
ab86662ab499e1f29c0f8c4248771e730c281e3f. This patch
adds some configure magic.
|
|
Solaris requires -lsocket to be able to talk to
the any2ppm daemon over unix domain sockets.
|
|
The configure test for __attribute__((constructor)) succeeds when
compiling with Sun Studio 12 on OpenSolaris but the attribute
is just ignored and has no actual effect. This causes the test
suite to not run any tests at all. With this patch we revert to
always using make-cairo-test-constructors.pl.

Written by Vladimir Vukicevic to enable integration with Qt embedded
devices, this backend allows cairo code to target QPainter, and use
it as a source for other cairo backends.
This imports the sources from mozilla-central:
http://mxr.mozilla.org/mozilla-central/find?text=&kind=text&string=cairo-qpainter
renames them from cairo-qpainter to cairo-qt, and integrates the patch
by Oleg Romashin:
https://bugs.freedesktop.org/attachment.cgi?id=18953
And then attempts to restore 'make check' to full functionality.
However:
- C++ does not play well with the PLT symbol hiding, and leaks into the
global namespace. 'make check' fails at check-plt.sh
- Qt embeds a GUI into QApplication which it requires to construct any
QPainter drawable, i.e. used by the boilerplate to create a cairo-qt
surface, and this leaks fonts (cairo-ft-fonts no less) causing assertion
failures that all cairo objects are accounted for upon destruction.

"strictly recommended" is an odd phrase and though the stern warning is
appropriate as replacing a system library with a more limited version is
likely to cause mayhem, we are but mere servants and should be reserved in
our parlance.
|
|
As needed for cairo-test-trace.
|
|
It seems that everything up to this point in release-publish
worked fine, so with these fixes, hopefully the next run of
make release-publish will work without any snags.

This looks to be an ugly necessity to work-around the nasty issue that
we currently gtkdoc expect to be run inside the source tree. I'm sure
Behdad will be able to resolve this much more elegantly than this quick
and fragile attempt.
|
|
I must have read it three times and kept thinking, "but I *did*
just install gtk-doc", before I finally understood what it was
trying to tell me.
|
|
As an aide to tiny swapless systems write the rarely used bytes that
define type42 fonts into a deleted file and mmap them back into our
address space.
|
|
Try using clock_gettime() for a high resolution stable time source in
preference to the potentially unstable TSC.

As the number of places where we add valgrind client requests grows, it
becomes imperative that we should be able to disable them with a simple
configure time option.
|
|
Split the GLX context from the GL surface to enable use of an alternative
EGL interface.
|
|
test/invalid-matrix deliberately feeds garbage into the API to test our
error detection. This causes FPE to be raised during the course of the
test - so they are deliberately disable for the duration. However, the
exceptions were not being cleared and so the FPE could be triggered on
the next floating point operation. This was being masked during make check,
by the fact that each test is run in its own forked process and was only
observed when multiple tests were run in foreground mode.
|
|
Remove the duplication of the compile line and enable shave to replace it
entirely with a "CHECK $header". This should make errors more obvious.
|
|
Add --tag=CC to the libtool invocations.
|
|
|
|
|
|
shave transforms the messy output of autotools into a pretty (quiet!)
Kbuild-like one.
Lets see how controversial a simple change can be...
|
|
Include zlib and libpng dependencies using something like '$(cairo_dir)/../zlib/zdll.lib'
instead of just 'zdll.lib'. Also, do similarly for the headers.
|
|
Adds a new, fake, fontconfig font backend. Fontconfig can be disabled
using --disable-fc, in which case the toy text API wont find fonts and
the internal font will always be used.
Also defines the feature macro CAIRO_HAS_FC_FONT. The two fontconfig-specific
functions in cairo-ft.h depend on that macro now.
|
|
It doesn't work for non GCC compiler right now, as "-Werror -Wall" is
an error to non GCC compiler.
I swapped the sequence of build/configure.ac.system and build/
configure.ac.warnings, then WARN_CFLAGS can be used.
|

The SDL backend makes invalid assumptions about SDL_Surface locking
semantics and doesn't deal correctly with the unpremultiplied pixel
format supported by SDL. Removed as per discussion on the mailing list.
