* | dispatch: Fix GLES3 symbol lookupAdam Jackson2018-07-061-1/+1
| | | | | | | | | | Looking for a symbol named "libGLESv2.so.2" is probably not going to work very well.

| * | Define _GNU_SOURCE for strdup()issue-181Emmanuele Bassi2018-06-182-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | The strdup() function is available on uClibc if _XOPEN_SOURCE_EXTENDED is defined; since we're using _GNU_SOURCE elsewhere to enable extended libc features, and uClibc will set _XOPEN_SOURCE_EXTENDED if _GNU_SOURCE is set, let's use that. Closes #181

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When building on macOS we don't have access to EGL, and GLX support is conditional. We should ensure we're using the appropriate paths depending on the platform, and protect our use of macros to avoid undefined symbols. Closes: #176

* | dispatch: Try harder to avoid calling the resolver1.5.2Adam Jackson2018-05-171-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Our caller may load (eg) epoxy_glAlphaFunc, which is a function pointer, and then call through that value multiple times. Until the caller re-examines the value of that function pointer, which is a copy relocation in the executable, repeated calls mean repeated work resolving the GL function. We can't make the caller reinspect the variable, but the resolver function can avoid doing redundant work. Fixes: anholt/libepoxy#171 Signed-off-by: Adam Jackson <ajax@redhat.com>
* | Use -Bsymbolic-functions instead of -BsymbolicEmmanuele Bassi2018-05-172-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Epoxy updates the function pointers in order to avoid calling the resolver multiple times, but with -Bsymbolic we're going to update the copy inside libepoxy, instead of the relocated copy in the code using libepoxy. This leads to libepoxy constantly querying the function resolver code instead of just once. We still want to avoid intra-library relocations for our functions, but we need to live with them for our global function pointers. See issue #171
* | Use abort() instead of exit(1)Emmanuele Bassi2018-05-171-3/+3
| | | | | | | | | | | | We want to consistently handle exceptions for the internal state checks; calling `exit()` does not allow us to attach a debugger and get a proper trace.

| | | | | | | | | | | | | | | | | | | | | | | | FreeBSD hides declarations of non-POSIX functions when POSIX macros, such as _POSIX_C_SOURCE or _XOPEN_SOURCE, is defined. This causes test/dlwrap.c to fail to compile because it uses dlvsym and asprintf. Fixes: #169

| | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we're being conservative about probing libraries, these entrypoints would not succeed unless the caller had already dlopened stuff themselves, or had explicitly linked against the provider library.

|\ \ | | | | | | Even more gentle glx detection
| * | dispatch: Be even gentler about probing for GLXAdam Jackson2018-04-301-34/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dlsym(NULL) can only see (symbols in) libraries that are loaded RTLD_GLOBAL, but our dlopen()s are RTLD_LOCAL and probably so was the one the app did if it did one. So use RTLD_NOLOAD to probe for the library even if it's LOCAL, iff the lookup is non-fatal. Having done that, don't ever load any libraries on this path. We only perform this check while resolving rendering API functions, and the window system resolution paths already load the appropriate library if they need to. Since you have to have gone through a winsys to get a context, and our resolvers only run when a function is _called_, this would only introduce a failure mode if you tried to call a function without a context bound.

| * | dispatch: Query the EGL context version when bootstrapping on GLESAdam Jackson2018-04-301-10/+10
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | We're about to change our dlopen paths to do RTLD_NOLOAD more aggressively. The issue then is we can create an EGL GLES context without libGLES* ever being loaded. test/egl_gles2_without_glx will fail in such a world: the first gentle probe for libGLESv2 will fail, then the less-gentle probe for libGLESv1_CM will be shot down by the test, and we exit. Fortunately by the time we've gotten to this point the context exists, so we can query its version via EGL instead. Signed-off-by: Adam Jackson <ajax@redhat.com>
* | test/glx_public_api_core: Fail softer if core contexts aren't availableAdam Jackson2018-04-301-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | If you've built Mesa with --disable-texture-float, and try to run the tests against Xvfb, glx_public_api_core will fail: creating a direct context with llvmpipe will fail because you don't have ARB_texture_float, and the internal fallback to an indirect context will fail because indirect only supports through 1.4. So the server will throw GLXBadFBConfig at you to say "I don't support core contexts", which we should interpret as a skip not a failure. Signed-off-by: Adam Jackson <ajax@redhat.com>

* | meson: Conditionally test for linker flagsEmmanuele Bassi2018-04-251-6/+6
| | | | | | | | | | | | | | | | Meson 0.46 introduced a function to check for linker flags passed to the compiler; since the version is really brand new, I don't want to bump the dependency on Meson just yet, so we're going to conditionally use get_supported_link_arguments() only if we're building with Meson 0.46 or later.

| | | | | | | | | | | | | | | | | | | | | Even though meson will find the dependency gl on macOS, this does not mean that there is a pkg-config file for it, as meson does not use pkg-config to establish its presence. It should therefore not be added to the libepoxy pkg-config file as a (private) requirement.

| | | | | | | | | | | | | | | | | | | | | | | | As per the previous commit, instead of assuming that Apple doesn't have dlvsym but everywhere else does, actually check for dlvsym() existing as that function is glibc-specific.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | build_apple was introduced in 756dca as a proxy for the fact that Apple's libc doesn't have dlvsym(), which is glibc-specific so also isn't present in other libc implementations such as musl. Instead of detecting whether we are building for Apple or not, just probe the to see if we have dlvsym.

* | Support encoding minor versions bigger than 10Emmanuele Bassi2018-02-241-3/+9
| | | | | | | | | | | | | | | | | | | | | | The GL version minor numbers haven't hit 10, yet, but if they do we're going to get non-sensical encoded versions when calling epoxy_gl_version(), like we're getting right now, with the GLSL version numbers. If the minor number is larger than the multiplication factor used for the major number, we should bump up the factor to the next order of magnitude.
* | meson: Use get_supported_arguments()Emmanuele Bassi2018-02-241-6/+1
| | | | | | | | | | | | | | Instead of iterating over the list of compiler flags, we should use the get_supported_arguments() method of the compiler object, which does it for us — and maybe, in the future, will be optimised to do the checks in parallel.
