From bf5f69c1aadb4405167e5bf03c58cc83f0ef6b20 Mon Sep 17 00:00:00 2001 From: Tuukka Lehtonen Date: Mon, 12 Sep 2016 23:17:54 +0300 Subject: [PATCH] Refresh native part of org.simantics.fastlz compilation instructions. Added Visual Studio 2012 solution/project for compiling with Microsoft Platform SDK for Windows Server 2003 R2. Renamed libfastlz-darwin-x86_64.jnilib to libfastlz-darwin-x86_64.dylib since .dylib is what System.mapLibraryName adds to library names. Also updated compile.sh to produce .dylib on Darwin. Removed LZ4 codes from the native codebase, they are already elsewhere and don't belong here anymore. refs #6675 Change-Id: I8dc95c5f91bc906c627b47e32ee1b9d1b6a4cb6d Signed-off-by: Tuukka Lehtonen --- .../impl/DecompressingInputStream.java | 8 +- bundles/org.simantics.fastlz/LICENSE | 36 +- bundles/org.simantics.fastlz/README.txt | 6 +- bundles/org.simantics.fastlz/native/Makefile | 20 - .../native/compile-x64.bat | 4 +- .../native/compile-x86.bat | 4 +- .../org.simantics.fastlz/native/compile.bat | 4 +- .../org.simantics.fastlz/native/compile.sh | 4 +- .../org.simantics.fastlz/native/jniWrapper.c | 68 -- bundles/org.simantics.fastlz/native/lz4.c | 819 ------------------ bundles/org.simantics.fastlz/native/lz4.h | 120 --- .../native/lz4_format_description.txt | 121 --- bundles/org.simantics.fastlz/native/lz4hc.c | 663 -------------- bundles/org.simantics.fastlz/native/lz4hc.h | 60 -- .../native/vs2012/fastlz.sln | 26 + .../native/vs2012/fastlz.vcxproj | 188 ++++ .../native/vs2012/fastlz.vcxproj.filters | 30 + ...4.jnilib => libfastlz-darwin-x86_64.dylib} | Bin .../fastlz/java/FastLZJavaInputStream.java | 5 + .../simantics/fastlz/FastLZBasicTests.java | 1 - 20 files changed, 267 insertions(+), 1920 deletions(-) delete mode 100644 bundles/org.simantics.fastlz/native/Makefile delete mode 100644 bundles/org.simantics.fastlz/native/lz4.c delete mode 100644 bundles/org.simantics.fastlz/native/lz4.h delete mode 100644 bundles/org.simantics.fastlz/native/lz4_format_description.txt delete mode 100644 bundles/org.simantics.fastlz/native/lz4hc.c delete mode 100644 bundles/org.simantics.fastlz/native/lz4hc.h create mode 100644 bundles/org.simantics.fastlz/native/vs2012/fastlz.sln create mode 100644 bundles/org.simantics.fastlz/native/vs2012/fastlz.vcxproj create mode 100644 bundles/org.simantics.fastlz/native/vs2012/fastlz.vcxproj.filters rename bundles/org.simantics.fastlz/src/{libfastlz-darwin-x86_64.jnilib => libfastlz-darwin-x86_64.dylib} (100%) diff --git a/bundles/org.simantics.compressions/src/org/simantics/compressions/impl/DecompressingInputStream.java b/bundles/org.simantics.compressions/src/org/simantics/compressions/impl/DecompressingInputStream.java index 8c7987177..9329d83c4 100644 --- a/bundles/org.simantics.compressions/src/org/simantics/compressions/impl/DecompressingInputStream.java +++ b/bundles/org.simantics.compressions/src/org/simantics/compressions/impl/DecompressingInputStream.java @@ -134,16 +134,20 @@ public abstract class DecompressingInputStream extends InputStream { return true; } - private static ByteBuffer ensureBufferSize(ByteBuffer buffer, int minCapacity) { + private ByteBuffer ensureBufferSize(ByteBuffer buffer, int minCapacity) { int oldCapacity = buffer != null ? buffer.capacity() : 0; if (buffer == null || oldCapacity < minCapacity) { int newCapacity = grow(oldCapacity, minCapacity); //System.out.println("ensureBufferSize(" + oldCapacity + ", " + minCapacity + "), new capacity " + newCapacity); - buffer = ByteBuffer.allocateDirect(newCapacity); + buffer = allocateBuffer(newCapacity); } return buffer; } + protected ByteBuffer allocateBuffer(int capacity) { + return ByteBuffer.allocateDirect(capacity); + } + /** * @param oldCapacity current capacity of a buffer * @param minCapacity diff --git a/bundles/org.simantics.fastlz/LICENSE b/bundles/org.simantics.fastlz/LICENSE index 299e8e19c..c7d105725 100644 --- a/bundles/org.simantics.fastlz/LICENSE +++ b/bundles/org.simantics.fastlz/LICENSE @@ -24,38 +24,4 @@ FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
