When tunnels entirely above ground were avoided, the
missing pseudorandom calls changed the allowed caves.
Now, above ground tunnels are not placed while
still running all previous pseudorandom calls.
Previously, sound failed due to errors with hardfp abi build
instructions. As the problem couldn't be found, the softfp
compatible abi was chosen instead.
This move will cause a small performance overhead, but due to the
abi being armeabi-v7a, the internal calculations will still be done
using the FPU.
We also fix some issues with ABI information passing. However, the
fixes aren't sufficient to get sound working.
The patch also fixes an issue with the gitignore file.
Multiplying by a factor of 1/1000.f (rather than dividing by 1000.f) directly
introduces an error of 1 ULP. With this patch, an exact comparison of a
floating point literal with the deserialized F1000 form representing it is now
guaranteed to be successful.
In addition, the maxmium and minimum safely representible floating point
numbers are now well-defined as constants.
Before, android_version.h got changed at every new commit. Now, we
only change it with new minetest releases. Analogous to how cmake
does it, we add an android_version_githash.h file that communicates
the git hash to C++ code.
Also, unify VERS_MAJOR, VERS_MINOR and VERS_PATCH variable
calculation inside the whole makefile.
Speeding up rebuild:
Before, we've written the android_version.h file at every rebuild.
As it thought the file's content has changed, make has rebuilt files
in the source tree that depended on that header file during rebuild,
causing lots of files being rebuilt without there being a reason.
The reasoning of make can be observed by passing -d and V=1 params
to the ndk-build command. You then got logging entries like:
Prerequisite `jni/src/android_version.h' is newer than target `obj/local/armeabi-v7a-hard/objs-debug/minetest/jni/src/areastore.o'.
Preventing race condition build fail:
Before, there was a race condition, where, if the prep_srcdir target
was executed in parallel with the $(ROOT)/jni/src/android_version.h
one, it could happen that the jni/src directory was nonexistent, and
we were trying to write into a file inside. This resulted in a build
failue:
/bin/sh: 1: cannot create [...]/jni/src/android_version.h: Directory nonexistent
Additionally, we now don't remove the link to src/ needlessly anymore.
Keeping this wouldn't have affected the rebuild, but this way its
more proper.
-> Remove the SendableMediaAnnouncement struct
-> Forge the packet directly in the m_media loop, spare one loop and the construction of a vector
-> Use preincrement to spare iterator copies
Before, our libiconv build was a joke. We first called configure for our own build host system,
then called make, before we executed a Android.mk script we provided as patch. The first "native make"
always failed, and the LIBICONV_LIB file setting in our Makefile didn't match the built one,
resulting in an always-rebuild of iconv.
This commit cleans up this total mess, removes the double-build, and the Android.mk, and properly calls
./configure with the according target platform, and uses a built toolchain.
As we have to deal with the android bug "NDK: Support for prebuild libs with full sonames"
https://code.google.com/p/android/issues/detail?id=55868
as the 2013 patch
https://lists.gnu.org/archive/html/libtool-patches/2013-06/msg00002.html
by Google's David Turner wasn't inside the 2011 libtool, we pass -avoid-version to
libtool.
Thanks to the proper build, wide_to_utf8 works for android now, removing us of the need to disable it.
