Defining (or undefining or redefining) the macro yourself results in undefined behaviour. If the system's C library doesn't expose support for C99 or 'long long' then telling libstdc++ that it does isn't going to work. It will just mean libstdc++ tries to use features that don't actually exist in the C library. In any case, systems that don't support C99 are probably not relevant to anybody nowadays.

charset=UTF-8 Content-Transfer-Encoding: 8bit * Make boost::Placeholders::_1 visible Fixes https://github.com/slic3r/Slic3r/issues/4967 * Use boost/nowide/cstdlib.hpp instead of boost/nowide/cenv.hpp * Do not undefine __STRICT_ANSI__ The `__STRICT_ANSI__` macro is defined by the compiler and it's undefined to undefine or redefine it. Using `-U__STRICT_ANSI__ -std=c++11` is just silly. If you don't want strict mode, don't ask for strict mode. Certainly don't ask for strict mode and then undefined the macro that is defined by strict mode. The correct solution is `-std=gnu++11` which doesn't define the macro in the first place. * Help Slic3r::_Log out by adding methods to cover const char* and const wchar_t* (so our tests pass and things don't break when passed string literals). * calculation of COG in Slic3r (#4970) Implement center of gravity (COG) calculation and gcode output in Slic3r. * Comment out cpp travis osx until it's sorted * Fix misc. typos (#4857) * Fix misc. typos Found via `codespell -q 3 -S *.po,./t,./xs/t,./xs/xsp -L ot,uin` * Follow-up typo fixes * set progress on deploy script to avoid timeouts * cpp porting: TransformationMatrix class tests (#4906) * cpp porting: transformation class testing * reword some tests * remove obsolete include * change equality threshold implementation * semicolons help in C++ * Stop defining _GLIBCXX_USE_C99 (#4981) This is an internal macro defined by libstdc++ to record the result of configure checks done when GCC was built. Defining (or undefining or redefining) the macro yourself results in undefined behaviour. If the system's C library doesn't expose support for C99 or 'long long' then telling libstdc++ that it does isn't going to work. It will just mean libstdc++ tries to use features that don't actually exist in the C library. In any case, systems that don't support C99 are probably not relevant to anybody nowadays. Fixes #4975 * fix-cmake-boost-1-70+ (#4980) * Use boost/nowide/cstdlib.hpp instead of boost/nowide/cenv.hpp * Patch build to work on Boost 1.73 and older versions as well. * Add missing usage of boost::placeholders. * Add a using for boost versions > 1.73 Co-authored-by: Jonathan Wakely Co-authored-by: Jonathan Wakely Co-authored-by: Roman Dvořák Co-authored-by: luzpaz Co-authored-by: Michael Kirsch --- src/CMakeLists.txt | 25 +++++++++++++++---------- xs/Build.PL | 9 +++++++++ xs/src/exprtk/exprtk.hpp | 4 ++-- xs/src/libslic3r/ConfigBase.cpp | 5 +++++ xs/src/libslic3r/GCodeSender.hpp | 11 +++++++++++ xs/src/libslic3r/GCodeTimeEstimator.cpp | 10 +++++++++- xs/src/libslic3r/PrintObject.cpp | 8 ++++++++ xs/src/libslic3r/SLAPrint.cpp | 8 ++++++++ xs/src/libslic3r/SupportMaterial.cpp | 5 +++++ xs/src/libslic3r/TriangleMesh.cpp | 9 +++++++++ 10 files changed, 81 insertions(+), 13 deletions(-) diff --git a/src/CMakeLists.txt b/src/CMakeLists.txt index d288999c1b..800d80cf17 100644 --- a/src/CMakeLists.txt +++ b/src/CMakeLists.txt @@ -115,7 +115,7 @@ endif(NOT GIT_VERSION STREQUAL "") find_package(Threads REQUIRED) set(Boost_NO_BOOST_CMAKE ON) -find_package(Boost REQUIRED COMPONENTS system thread filesystem) +find_package(Boost REQUIRED COMPONENTS system thread filesystem OPTIONAL_COMPONENTS nowide) set(LIBDIR ${CMAKE_CURRENT_SOURCE_DIR}/../xs/src/) set(GUI_LIBDIR ${CMAKE_CURRENT_SOURCE_DIR}/GUI/) @@ -231,6 +231,9 @@ add_library(libslic3r STATIC target_compile_features(libslic3r PUBLIC cxx_std_11) target_include_directories(libslic3r SYSTEM PUBLIC ${SLIC3R_INCLUDES}) target_include_directories(libslic3r PUBLIC ${LIBSLIC3R_INCLUDES}) +if (BOOST_NOWIDE_FOUND) + target_compile_options(libslic3r -DBOOST_INCLUDE_NOWIDE) +endif() add_library(BSpline STATIC ${LIBDIR}/BSpline/BSpline.cpp @@ -499,15 +502,17 @@ endif() # Windows needs a compiled component for Boost.nowide IF (WIN32) - add_library(boost-nowide STATIC - ${LIBDIR}/boost/nowide/iostream.cpp - ) - if(MSVC) - # Tell boost pragmas to not rename nowide as we are building it - add_definitions(-DBOOST_NOWIDE_NO_LIB) - endif() - target_link_libraries(slic3r boost-nowide) - target_include_directories(boost-nowide PUBLIC ${COMMON_INCLUDES}) + if (NOT BOOST_NOWIDE_FOUND) + add_library(boost-nowide STATIC + ${LIBDIR}/boost/nowide/iostream.cpp + ) + if(MSVC) + # Tell boost pragmas to not rename nowide as we are building it + add_definitions(-DBOOST_NOWIDE_NO_LIB) + endif() + target_link_libraries(slic3r boost-nowide) + target_include_directories(boost-nowide PUBLIC ${COMMON_INCLUDES}) + endif() # MinGW apparently has some multiple definitions of UUID-related items # deal with it. diff --git a/xs/Build.PL b/xs/Build.PL index 35356b8733..0655b7c12d 100644 --- a/xs/Build.PL +++ b/xs/Build.PL @@ -151,18 +151,27 @@ if (defined $ENV{BOOST_LIBRARYPATH}) { } # In order to generate the -l switches we need to know how Boost libraries are named my $have_boost = 0;

Previously, if the inflator was starved of bytes and could not make progress (because the input buffer was empty and the caller did not set the TINFL_FLAG_HAS_MORE_INPUT flag - say on truncated or corrupted compressed data stream) it would append all 0's to the input and try to soldier on. This is scary behavior if the caller didn't know when to stop accepting output (because it didn't know how much uncompressed data was expected, or didn't enforce a sane maximum). v1.16 will instead return TINFL_STATUS_FAILED_CANNOT_MAKE_PROGRESS immediately if it needs 1 or more bytes to make progress, the input buf is empty, and the caller has indicated that no more input is available.

Previously, if the inflator was starved of bytes and could not make progress (because the input buffer was empty and the + caller did not set the TINFL_FLAG_HAS_MORE_INPUT flag - say on truncated or corrupted compressed data stream) it would append all 0's to the input and try to soldier on. + This is scary, because in the worst case, I believe it was possible for the prev. inflator to start outputting large amounts of literal data.

Fixed the MZ_ZIP_FLAG_DO_NOT_SORT_CENTRAL_DIRECTORY bug (thanks kahmyong.moon@hp.com), which could cause the locate files func to not find files when this flag was specified. Also fixed a bug in mz_zip_reader_extract_to_mem_no_alloc() with user provided read buffers (thanks kymoon). I also merged lots of compiler fixes from various github repo branches and Google Code issue reports. I finally added cmake support (only tested under for Linux so far), compiled and tested with clang v3.3 and gcc 4.6 (under Linux), added defl_write_image_to_png_file_in_memory_ex() (supports Y flipping for OpenGL use, real-time compression), added a new PNG example (example6.c - Mandelbrot), and I added 64-bit file I/O support (stat64(), etc.) for glibc. + +- Critical fix for the MZ_ZIP_FLAG_DO_NOT_SORT_CENTRAL_DIRECTORY bug (thanks kahmyong.moon@hp.com) which could cause locate files to not find files. This bug + would only have occured in earlier versions if you explicitly used this flag, OR if you used mz_zip_extract_archive_file_to_heap() or mz_zip_add_mem_to_archive_file_in_place() + (which used this flag). If you can't switch to v1.15 but want to fix this bug, just remove the uses of this flag from both helper funcs (and of course don't use the flag). +- Bugfix in mz_zip_reader_extract_to_mem_no_alloc() from kymoon when pUser_read_buf is not NULL and compressed size is > uncompressed size +- Fixing mz_zip_reader_extract_*() funcs so they don't try to extract compressed data from directory entries, to account for weird zipfiles which contain zero-size compressed data on dir entries. + Hopefully this fix won't cause any issues on weird zip archives, because it assumes the low 16-bits of zip external attributes are DOS attributes (which I believe they always are in practice). +- Fixing mz_zip_reader_is_file_a_directory() so it doesn't check the internal attributes, just the filename and external attributes +- mz_zip_reader_init_file() - missing MZ_FCLOSE() call if the seek failed +- Added cmake support for Linux builds which builds all the examples, tested with clang v3.3 and gcc v4.6. +- Clang fix for tdefl_write_image_to_png_file_in_memory() from toffaletti +- Merged MZ_FORCEINLINE fix from hdeanclark +- Fix include before config #ifdef, thanks emil.brink +- Added tdefl_write_image_to_png_file_in_memory_ex(): supports Y flipping (super useful for OpenGL apps), and explicit control over the compression level (so you can + set it to 1 for real-time compression). +- Merged in some compiler fixes from paulharris's github repro. +- Retested this build under Windows (VS 2010, including static analysis), tcc 0.9.26, gcc v4.6 and clang v3.3. +- Added example6.c, which dumps an image of the mandelbrot set to a PNG file. +- Modified example2 to help test the MZ_ZIP_FLAG_DO_NOT_SORT_CENTRAL_DIRECTORY flag more. +- In r3: Bugfix to mz_zip_writer_add_file() found during merge: Fix possible src file fclose() leak if alignment bytes+local header file write faiiled +- In r4: Minor bugfix to mz_zip_writer_add_from_zip_reader(): Was pushing the wrong central dir header offset, appears harmless in this release, but it became a problem in the zip64 branch + +### v1.14 - May 20, 2012 + +(SVN Only) Minor tweaks to get miniz.c compiling with the Tiny C Compiler, added #ifndef MINIZ_NO_TIME guards around utime.h includes. Adding mz_free() function, so the caller can free heap blocks returned by miniz using whatever heap functions it has been configured to use, MSVC specific fixes to use "safe" variants of several functions (localtime_s, fopen_s, freopen_s). + +MinGW32/64 GCC 4.6.1 compiler fixes: added MZ_FORCEINLINE, #include (thanks fermtect). + +Compiler specific fixes, some from fermtect. I upgraded to TDM GCC 4.6.1 and now static __forceinline is giving it fits, so I'm changing all usage of __forceinline to MZ_FORCEINLINE and forcing gcc to use __attribute__((__always_inline__)) (and MSVC to use __forceinline). Also various fixes from fermtect for MinGW32: added #include , 64-bit ftell/fseek fixes. + +### v1.13 - May 19, 2012 + +From jason@cornsyrup.org and kelwert@mtu.edu - Most importantly, fixed mz_crc32() so it doesn't compute the wrong CRC-32's when mz_ulong is 64-bits. Temporarily/locally slammed in "typedef unsigned long mz_ulong" and re-ran a randomized regression test on ~500k files. Other stuff: + +Eliminated a bunch of warnings when compiling with GCC 32-bit/64. Ran all examples, miniz.c, and tinfl.c through MSVC 2008's /analyze (static analysis) option and fixed all warnings (except for the silly "Use of the comma-operator in a tested expression.." analysis warning, which I purposely use to work around a MSVC compiler warning). + +Created 32-bit and 64-bit Codeblocks projects/workspace. Built and tested Linux executables. The codeblocks workspace is compatible with Linux+Win32/x64. Added miniz_tester solution/project, which is a useful little app derived from LZHAM's tester app that I use as part of the regression test. Ran miniz.c and tinfl.c through another series of regression testing on ~500,000 files and archives. Modified example5.c so it purposely disables a bunch of high-level functionality (MINIZ_NO_STDIO, etc.). (Thanks to corysama for the MINIZ_NO_STDIO bug report.) + +Fix ftell() usage in a few of the examples so they exit with an error on files which are too large (a limitation of the examples, not miniz itself). Fix fail logic handling in mz_zip_add_mem_to_archive_file_in_place() so it always calls mz_zip_writer_finalize_archive() and mz_zip_writer_end(), even if the file add fails. + +- From jason@cornsyrup.org and kelwert@mtu.edu - Fix mz_crc32() so it doesn't compute the wrong CRC-32's when mz_ulong is 64-bit. +- Temporarily/locally slammed in "typedef unsigned long mz_ulong" and re-ran a randomized regression test on ~500k files. +- Eliminated a bunch of warnings when compiling with GCC 32-bit/64. +- Ran all examples, miniz.c, and tinfl.c through MSVC 2008's /analyze (static analysis) option and fixed all warnings (except for the silly +"Use of the comma-operator in a tested expression.." analysis warning, which I purposely use to work around a MSVC compiler warning). +- Created 32-bit and 64-bit Codeblocks projects/workspace.

Thanks to Bruce Dawson for the feedback/bug report. + +### v1.11 - 5/28/11 + +Added statement from unlicense.org + +### v1.10 - 5/27/11 + +- Substantial compressor optimizations: +- Level 1 is now ~4x faster than before. The L1 compressor's throughput now varies between 70-110MB/sec. on a Core i7 (actual throughput varies depending on the type of data, and x64 vs. x86). +- Improved baseline L2-L9 compression perf. Also, greatly improved compression perf. issues on some file types. +- Refactored the compression code for better readability and maintainability. +- Added level 10 compression level (L10 has slightly better ratio than level 9, but could have a potentially large drop in throughput on some files). + +### v1.09 - 5/15/11 + +Initial stable release. + + diff --git a/xs/src/miniz/LICENSE b/xs/src/miniz/LICENSE new file mode 100644 index 0000000000..1982f4bb8f --- /dev/null +++ b/xs/src/miniz/LICENSE @@ -0,0 +1,22 @@ +Copyright 2013-2014 RAD Game Tools and Valve Software +Copyright 2010-2014 Rich Geldreich and Tenacious Software LLC + +All Rights Reserved. + +Permission is hereby granted, free of charge, to any person obtaining a copy +of this software and associated documentation files (the "Software"), to deal +in the Software without restriction, including without limitation the rights +to use, copy, modify, merge, publish, distribute, sublicense, and/or sell +copies of the Software, and to permit persons to whom the Software is +furnished to do so, subject to the following conditions: + +The above copyright notice and this permission notice shall be included in +all copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

Built and tested Linux executables. The codeblocks workspace is compatible with Linux+Win32/x64. - - Added miniz_tester solution/project, which is a useful little app derived from LZHAM's tester app that I use as part of the regression test. - - Ran miniz.c and tinfl.c through another series of regression testing on ~500,000 files and archives. - - Modified example5.c so it purposely disables a bunch of high-level functionality (MINIZ_NO_STDIO, etc.).

Thanks to Bruce Dawson for the feedback/bug report. - 5/28/11 v1.11 - Added statement from unlicense.org - 5/27/11 v1.10 - Substantial compressor optimizations: - - Level 1 is now ~4x faster than before. The L1 compressor's throughput now varies between 70-110MB/sec. on a - - Core i7 (actual throughput varies depending on the type of data, and x64 vs. x86). - - Improved baseline L2-L9 compression perf. Also, greatly improved compression perf. issues on some file types. - - Refactored the compression code for better readability and maintainability. - - Added level 10 compression level (L10 has slightly better ratio than level 9, but could have a potentially large - drop in throughput on some files). - 5/15/11 v1.09 - Initial stable release. - - * Low-level Deflate/Inflate implementation notes: - - Compression: Use the "tdefl" API's. The compressor supports raw, static, and dynamic blocks, lazy or - greedy parsing, match length filtering, RLE-only, and Huffman-only streams. It performs and compresses - approximately as well as zlib. - - Decompression: Use the "tinfl" API's. The entire decompressor is implemented as a single function - coroutine: see tinfl_decompress(). It supports decompression into a 32KB (or larger power of 2) wrapping buffer, or into a memory - block large enough to hold the entire file. - - The low-level tdefl/tinfl API's do not make any use of dynamic memory allocation. - - * zlib-style API notes: - - miniz.c implements a fairly large subset of zlib. There's enough functionality present for it to be a drop-in - zlib replacement in many apps: - The z_stream struct, optional memory allocation callbacks - deflateInit/deflateInit2/deflate/deflateReset/deflateEnd/deflateBound - inflateInit/inflateInit2/inflate/inflateEnd - compress, compress2, compressBound, uncompress - CRC-32, Adler-32 - Using modern, minimal code size, CPU cache friendly routines. - Supports raw deflate streams or standard zlib streams with adler-32 checking. - - Limitations: - The callback API's are not implemented yet. No support for gzip headers or zlib static dictionaries. - I've tried to closely emulate zlib's various flavors of stream flushing and return status codes, but - there are no guarantees that miniz.c pulls this off perfectly. - - * PNG writing: See the tdefl_write_image_to_png_file_in_memory() function, originally written by - Alex Evans. Supports 1-4 bytes/pixel images. - - * ZIP archive API notes: - - The ZIP archive API's where designed with simplicity and efficiency in mind, with just enough abstraction to - get the job done with minimal fuss. There are simple API's to retrieve file information, read files from - existing archives, create new archives, append new files to existing archives, or clone archive data from - one archive to another. It supports archives located in memory or the heap, on disk (using stdio.h), - or you can specify custom file read/write callbacks. - - - Archive reading: Just call this function to read a single file from a disk archive: - - void *mz_zip_extract_archive_file_to_heap(const char *pZip_filename, const char *pArchive_name, - size_t *pSize, mz_uint zip_flags); - - For more complex cases, use the "mz_zip_reader" functions. Upon opening an archive, the entire central - directory is located and read as-is into memory, and subsequent file access only occurs when reading individual files. - - - Archives file scanning: The simple way is to use this function to scan a loaded archive for a specific file: - - int mz_zip_reader_locate_file(mz_zip_archive *pZip, const char *pName, const char *pComment, mz_uint flags); - - The locate operation can optionally check file comments too, which (as one example) can be used to identify - multiple versions of the same file in an archive. This function uses a simple linear search through the central - directory, so it's not very fast. - - Alternately, you can iterate through all the files in an archive (using mz_zip_reader_get_num_files()) and - retrieve detailed info on each file by calling mz_zip_reader_file_stat(). - - - Archive creation: Use the "mz_zip_writer" functions. The ZIP writer immediately writes compressed file data - to disk and builds an exact image of the central directory in memory. The central directory image is written - all at once at the end of the archive file when the archive is finalized. - - The archive writer can optionally align each file's local header and file data to any power of 2 alignment, - which can be useful when the archive will be read from optical media. Also, the writer supports placing - arbitrary data blobs at the very beginning of ZIP archives. Archives written using either feature are still - readable by any ZIP tool. - - - Archive appending: The simple way to add a single file to an archive is to call this function: - - mz_bool mz_zip_add_mem_to_archive_file_in_place(const char *pZip_filename, const char *pArchive_name, - const void *pBuf, size_t buf_size, const void *pComment, mz_uint16 comment_size, mz_uint level_and_flags); - - The archive will be created if it doesn't already exist, otherwise it'll be appended to. - Note the appending is done in-place and is not an atomic operation, so if something goes wrong - during the operation it's possible the archive could be left without a central directory (although the local - file headers and file data will be fine, so the archive will be recoverable). - - For more complex archive modification scenarios: - 1. The safest way is to use a mz_zip_reader to read the existing archive, cloning only those bits you want to - preserve into a new archive using using the mz_zip_writer_add_from_zip_reader() function (which compiles the - compressed file data as-is). When you're done, delete the old archive and rename the newly written archive, and - you're done. This is safe but requires a bunch of temporary disk space or heap memory. - - 2. Or, you can convert an mz_zip_reader in-place to an mz_zip_writer using mz_zip_writer_init_from_reader(), - append new files as needed, then finalize the archive which will write an updated central directory to the - original archive. (This is basically what mz_zip_add_mem_to_archive_file_in_place() does.) There's a - possibility that the archive's central directory could be lost with this method if anything goes wrong, though. - - - ZIP archive support limitations: - No zip64 or spanning support. Extraction functions can only handle unencrypted, stored or deflated files. - Requires streams capable of seeking. - - * This is a header file library, like stb_image.c. To get only a header file, either cut and paste the - below header, or create miniz.h, #define MINIZ_HEADER_FILE_ONLY, and then include miniz.c from it. - - * Important: For best perf. be sure to customize the below macros for your target platform: - #define MINIZ_USE_UNALIGNED_LOADS_AND_STORES 1 - #define MINIZ_LITTLE_ENDIAN 1 - #define MINIZ_HAS_64BIT_REGISTERS 1 - - * On platforms using glibc, Be sure to "#define _LARGEFILE64_SOURCE 1" before including miniz.c to ensure miniz - uses the 64-bit variants: fopen64(), stat64(), etc. Otherwise you won't be able to process large files - (i.e. 32-bit stat() fails for me on files > 0x7FFFFFFF bytes). -*/ - -#ifndef MINIZ_HEADER_INCLUDED -#define MINIZ_HEADER_INCLUDED - -#include - -// Defines to completely disable specific portions of miniz.c: -// If all macros here are defined the only functionality remaining will be CRC-32, adler-32, tinfl, and tdefl. - -// Define MINIZ_NO_STDIO to disable all usage and any functions which rely on stdio for file I/O. -//#define MINIZ_NO_STDIO - -// If MINIZ_NO_TIME is specified then the ZIP archive functions will not be able to get the current time, or -// get/set file times, and the C run-time funcs that get/set times won't be called. -// The current downside is the times written to your archives will be from 1979. -//#define MINIZ_NO_TIME - -// Define MINIZ_NO_ARCHIVE_APIS to disable all ZIP archive API's. -//#define MINIZ_NO_ARCHIVE_APIS - -// Define MINIZ_NO_ARCHIVE_APIS to disable all writing related ZIP archive API's. -//#define MINIZ_NO_ARCHIVE_WRITING_APIS - -// Define MINIZ_NO_ZLIB_APIS to remove all ZLIB-style compression/decompression API's. -//#define MINIZ_NO_ZLIB_APIS - -// Define MINIZ_NO_ZLIB_COMPATIBLE_NAME to disable zlib names, to prevent conflicts against stock zlib. -//#define MINIZ_NO_ZLIB_COMPATIBLE_NAMES - -// Define MINIZ_NO_MALLOC to disable all calls to malloc, free, and realloc. -// Note if MINIZ_NO_MALLOC is defined then the user must always provide custom user alloc/free/realloc -// callbacks to the zlib and archive API's, and a few stand-alone helper API's which don't provide custom user -// functions (such as tdefl_compress_mem_to_heap() and tinfl_decompress_mem_to_heap()) won't work. -//#define MINIZ_NO_MALLOC - -#if defined(__TINYC__) && (defined(__linux) || defined(__linux__)) - // TODO: Work around "error: include file 'sys\utime.h' when compiling with tcc on Linux - #define MINIZ_NO_TIME -#endif - -#if !defined(MINIZ_NO_TIME) && !defined(MINIZ_NO_ARCHIVE_APIS) - #include -#endif - -#if defined(_M_IX86) || defined(_M_X64) || defined(__i386__) || defined(__i386) || defined(__i486__) || defined(__i486) || defined(i386) || defined(__ia64__) || defined(__x86_64__) -// MINIZ_X86_OR_X64_CPU is only used to help set the below macros. -#define MINIZ_X86_OR_X64_CPU 1 -#endif - -#if (__BYTE_ORDER__==__ORDER_LITTLE_ENDIAN__) || MINIZ_X86_OR_X64_CPU -// Set MINIZ_LITTLE_ENDIAN to 1 if the processor is little endian. -#define MINIZ_LITTLE_ENDIAN 1 -#endif - -#if MINIZ_X86_OR_X64_CPU -// Set MINIZ_USE_UNALIGNED_LOADS_AND_STORES to 1 on CPU's that permit efficient integer loads and stores from unaligned addresses. -#define MINIZ_USE_UNALIGNED_LOADS_AND_STORES 1 -#endif - -#if defined(_M_X64) || defined(_WIN64) || defined(__MINGW64__) || defined(_LP64) || defined(__LP64__) || defined(__ia64__) || defined(__x86_64__) -// Set MINIZ_HAS_64BIT_REGISTERS to 1 if operations on 64-bit integers are reasonably fast (and don't involve compiler generated calls to helper functions). -#define MINIZ_HAS_64BIT_REGISTERS 1 -#endif - -#ifdef __cplusplus -extern "C" { -#endif - -// ------------------- zlib-style API Definitions. - -// For more compatibility with zlib, miniz.c uses unsigned long for some parameters/struct members.

For example, to disable the archive related functions just define + MINIZ_NO_ARCHIVE_APIS, or to get rid of all stdio usage define MINIZ_NO_STDIO (see the list below for more macros). + + * Low-level Deflate/Inflate implementation notes: + + Compression: Use the "tdefl" API's. The compressor supports raw, static, and dynamic blocks, lazy or + greedy parsing, match length filtering, RLE-only, and Huffman-only streams. It performs and compresses + approximately as well as zlib. + + Decompression: Use the "tinfl" API's. The entire decompressor is implemented as a single function + coroutine: see tinfl_decompress(). It supports decompression into a 32KB (or larger power of 2) wrapping buffer, or into a memory + block large enough to hold the entire file. + + The low-level tdefl/tinfl API's do not make any use of dynamic memory allocation. + + * zlib-style API notes: + + miniz.c implements a fairly large subset of zlib. There's enough functionality present for it to be a drop-in + zlib replacement in many apps: + The z_stream struct, optional memory allocation callbacks + deflateInit/deflateInit2/deflate/deflateReset/deflateEnd/deflateBound + inflateInit/inflateInit2/inflate/inflateReset/inflateEnd + compress, compress2, compressBound, uncompress + CRC-32, Adler-32 - Using modern, minimal code size, CPU cache friendly routines. + Supports raw deflate streams or standard zlib streams with adler-32 checking. + + Limitations: + The callback API's are not implemented yet. No support for gzip headers or zlib static dictionaries. + I've tried to closely emulate zlib's various flavors of stream flushing and return status codes, but + there are no guarantees that miniz.c pulls this off perfectly. + + * PNG writing: See the tdefl_write_image_to_png_file_in_memory() function, originally written by + Alex Evans. Supports 1-4 bytes/pixel images. + + * ZIP archive API notes: + + The ZIP archive API's where designed with simplicity and efficiency in mind, with just enough abstraction to + get the job done with minimal fuss. There are simple API's to retrieve file information, read files from + existing archives, create new archives, append new files to existing archives, or clone archive data from + one archive to another. It supports archives located in memory or the heap, on disk (using stdio.h), + or you can specify custom file read/write callbacks. + + - Archive reading: Just call this function to read a single file from a disk archive: + + void *mz_zip_extract_archive_file_to_heap(const char *pZip_filename, const char *pArchive_name, + size_t *pSize, mz_uint zip_flags); + + For more complex cases, use the "mz_zip_reader" functions. Upon opening an archive, the entire central + directory is located and read as-is into memory, and subsequent file access only occurs when reading individual files. + + - Archives file scanning: The simple way is to use this function to scan a loaded archive for a specific file: + + int mz_zip_reader_locate_file(mz_zip_archive *pZip, const char *pName, const char *pComment, mz_uint flags); + + The locate operation can optionally check file comments too, which (as one example) can be used to identify + multiple versions of the same file in an archive. This function uses a simple linear search through the central + directory, so it's not very fast. + + Alternately, you can iterate through all the files in an archive (using mz_zip_reader_get_num_files()) and + retrieve detailed info on each file by calling mz_zip_reader_file_stat(). + + - Archive creation: Use the "mz_zip_writer" functions. The ZIP writer immediately writes compressed file data + to disk and builds an exact image of the central directory in memory. The central directory image is written + all at once at the end of the archive file when the archive is finalized. + + The archive writer can optionally align each file's local header and file data to any power of 2 alignment, + which can be useful when the archive will be read from optical media. Also, the writer supports placing + arbitrary data blobs at the very beginning of ZIP archives. Archives written using either feature are still + readable by any ZIP tool. + + - Archive appending: The simple way to add a single file to an archive is to call this function: + + mz_bool mz_zip_add_mem_to_archive_file_in_place(const char *pZip_filename, const char *pArchive_name, + const void *pBuf, size_t buf_size, const void *pComment, mz_uint16 comment_size, mz_uint level_and_flags); + + The archive will be created if it doesn't already exist, otherwise it'll be appended to. + Note the appending is done in-place and is not an atomic operation, so if something goes wrong + during the operation it's possible the archive could be left without a central directory (although the local + file headers and file data will be fine, so the archive will be recoverable). + + For more complex archive modification scenarios: + 1. The safest way is to use a mz_zip_reader to read the existing archive, cloning only those bits you want to + preserve into a new archive using using the mz_zip_writer_add_from_zip_reader() function (which compiles the + compressed file data as-is). When you're done, delete the old archive and rename the newly written archive, and + you're done. This is safe but requires a bunch of temporary disk space or heap memory. + + 2. Or, you can convert an mz_zip_reader in-place to an mz_zip_writer using mz_zip_writer_init_from_reader(), + append new files as needed, then finalize the archive which will write an updated central directory to the + original archive. (This is basically what mz_zip_add_mem_to_archive_file_in_place() does.) There's a + possibility that the archive's central directory could be lost with this method if anything goes wrong, though. + + - ZIP archive support limitations: + No zip64 or spanning support. Extraction functions can only handle unencrypted, stored or deflated files. + Requires streams capable of seeking. + + * This is a header file library, like stb_image.c. To get only a header file, either cut and paste the + below header, or create miniz.h, #define MINIZ_HEADER_FILE_ONLY, and then include miniz.c from it. + + * Important: For best perf. be sure to customize the below macros for your target platform: + #define MINIZ_USE_UNALIGNED_LOADS_AND_STORES 1 + #define MINIZ_LITTLE_ENDIAN 1 + #define MINIZ_HAS_64BIT_REGISTERS 1 + + * On platforms using glibc, Be sure to "#define _LARGEFILE64_SOURCE 1" before including miniz.c to ensure miniz + uses the 64-bit variants: fopen64(), stat64(), etc. Otherwise you won't be able to process large files + (i.e. 32-bit stat() fails for me on files > 0x7FFFFFFF bytes). +*/ +#pragma once + + + + + +/* Defines to completely disable specific portions of miniz.c: + If all macros here are defined the only functionality remaining will be CRC-32, adler-32, tinfl, and tdefl. */ + +/* Define MINIZ_NO_STDIO to disable all usage and any functions which rely on stdio for file I/O. */ +/*#define MINIZ_NO_STDIO */ + +/* If MINIZ_NO_TIME is specified then the ZIP archive functions will not be able to get the current time, or */ +/* get/set file times, and the C run-time funcs that get/set times won't be called. */ +/* The current downside is the times written to your archives will be from 1979. */ +/*#define MINIZ_NO_TIME */ + +/* Define MINIZ_NO_ARCHIVE_APIS to disable all ZIP archive API's. */ +/*#define MINIZ_NO_ARCHIVE_APIS */ + +/* Define MINIZ_NO_ARCHIVE_WRITING_APIS to disable all writing related ZIP archive API's. */ +/*#define MINIZ_NO_ARCHIVE_WRITING_APIS */ + +/* Define MINIZ_NO_ZLIB_APIS to remove all ZLIB-style compression/decompression API's. */ +/*#define MINIZ_NO_ZLIB_APIS */ + +/* Define MINIZ_NO_ZLIB_COMPATIBLE_NAME to disable zlib names, to prevent conflicts against stock zlib. */ +/*#define MINIZ_NO_ZLIB_COMPATIBLE_NAMES */ + +/* Define MINIZ_NO_MALLOC to disable all calls to malloc, free, and realloc. + Note if MINIZ_NO_MALLOC is defined then the user must always provide custom user alloc/free/realloc + callbacks to the zlib and archive API's, and a few stand-alone helper API's which don't provide custom user + functions (such as tdefl_compress_mem_to_heap() and tinfl_decompress_mem_to_heap()) won't work. */ +/*#define MINIZ_NO_MALLOC */ + +#if defined(__TINYC__) && (defined(__linux) || defined(__linux__)) +/* TODO: Work around "error: include file 'sys\utime.h' when compiling with tcc on Linux */ +#define MINIZ_NO_TIME +#endif + +#include + +#if !defined(MINIZ_NO_TIME) && !defined(MINIZ_NO_ARCHIVE_APIS) +#include +#endif + +#if defined(_M_IX86) || defined(_M_X64) || defined(__i386__) || defined(__i386) || defined(__i486__) || defined(__i486) || defined(i386) || defined(__ia64__) || defined(__x86_64__) +/* MINIZ_X86_OR_X64_CPU is only used to help set the below macros. */ +#define MINIZ_X86_OR_X64_CPU 1 +#else +#define MINIZ_X86_OR_X64_CPU 0 +#endif + +#if (__BYTE_ORDER__ == __ORDER_LITTLE_ENDIAN__) || MINIZ_X86_OR_X64_CPU +/* Set MINIZ_LITTLE_ENDIAN to 1 if the processor is little endian. */ +#define MINIZ_LITTLE_ENDIAN 1 +#else +#define MINIZ_LITTLE_ENDIAN 0 +#endif + +/* Set MINIZ_USE_UNALIGNED_LOADS_AND_STORES only if not set */ +#if !defined(MINIZ_USE_UNALIGNED_LOADS_AND_STORES) +#if MINIZ_X86_OR_X64_CPU +/* Set MINIZ_USE_UNALIGNED_LOADS_AND_STORES to 1 on CPU's that permit efficient integer loads and stores from unaligned addresses. */ +#define MINIZ_USE_UNALIGNED_LOADS_AND_STORES 1 +#define MINIZ_UNALIGNED_USE_MEMCPY +#else +#define MINIZ_USE_UNALIGNED_LOADS_AND_STORES 0 +#endif +#endif + +#if defined(_M_X64) || defined(_WIN64) || defined(__MINGW64__) || defined(_LP64) || defined(__LP64__) || defined(__ia64__) || defined(__x86_64__) +/* Set MINIZ_HAS_64BIT_REGISTERS to 1 if operations on 64-bit integers are reasonably fast (and don't involve compiler generated calls to helper functions). */ +#define MINIZ_HAS_64BIT_REGISTERS 1 +#else +#define MINIZ_HAS_64BIT_REGISTERS 0 +#endif + +#ifdef __cplusplus +extern "C" { +#endif + +/* ------------------- zlib-style API Definitions. */ + +/* For more compatibility with zlib, miniz.c uses unsigned long for some parameters/struct members.

It supports the most commonly used functions exported by the zlib library, but is a completely independent implementation so zlib's licensing requirements do not apply. Miniz also contains simple to use functions for writing .PNG format image files and reading/writing/appending .ZIP format archives. Miniz's compression speed has been tuned to be comparable to zlib's, and it also has a specialized real-time compressor function designed to compare well against fastlz/minilzo. + +## Usage + +Please use the files from the [releases page](https://github.com/richgel999/miniz/releases) in your projects. Do not use the git checkout directly! The different source and header files are [amalgamated](https://www.sqlite.org/amalgamation.html) into one `miniz.c`/`miniz.h` pair in a build step (`amalgamate.sh`). Include `miniz.c` and `miniz.h` in your project to use Miniz. + +## Features + +* MIT licensed +* A portable, single source and header file library written in plain C. Tested with GCC, clang and Visual Studio. +* Easily tuned and trimmed down by defines +* A drop-in replacement for zlib's most used API's (tested in several open source projects that use zlib, such as libpng and libzip). +* Fills a single threaded performance vs. compression ratio gap between several popular real-time compressors and zlib. For example, at level 1, miniz.c compresses around 5-9% better than minilzo, but is approx. 35% slower. At levels 2-9, miniz.c is designed to compare favorably against zlib's ratio and speed. See the miniz performance comparison page for example timings. +* Not a block based compressor: miniz.c fully supports stream based processing using a coroutine-style implementation. The zlib-style API functions can be called a single byte at a time if that's all you've got. +* Easy to use. The low-level compressor (tdefl) and decompressor (tinfl) have simple state structs which can be saved/restored as needed with simple memcpy's. The low-level codec API's don't use the heap in any way. +* Entire inflater (including optional zlib header parsing and Adler-32 checking) is implemented in a single function as a coroutine, which is separately available in a small (~550 line) source file: miniz_tinfl.c +* A fairly complete (but totally optional) set of .ZIP archive manipulation and extraction API's. The archive functionality is intended to solve common problems encountered in embedded, mobile, or game development situations. (The archive API's are purposely just powerful enough to write an entire archiver given a bit of additional higher-level logic.) + +## Known Problems + +* No support for encrypted archives. Not sure how useful this stuff is in practice. +* Minimal documentation. The assumption is that the user is already familiar with the basic zlib API. I need to write an API wiki - for now I've tried to place key comments before each enum/API, and I've included 6 examples that demonstrate how to use the module's major features. + +## Special Thanks + +Thanks to Alex Evans for the PNG writer function. Also, thanks to Paul Holden and Thorsten Scheuermann for feedback and testing, Matt Pritchard for all his encouragement, and Sean Barrett's various public domain libraries for inspiration (and encouraging me to write miniz.c in C, which was much more enjoyable and less painful than I thought it would be considering I've been programming in C++ for so long). + +Thanks to Bruce Dawson for reporting a problem with the level_and_flags archive API parameter (which is fixed in v1.12) and general feedback, and Janez Zemva for indirectly encouraging me into writing more examples. + +## Patents + +I was recently asked if miniz avoids patent issues. miniz purposely uses the same core algorithms as the ones used by zlib. The compressor uses vanilla hash chaining as described [here](http://www.gzip.org/zlib/rfc-deflate.html#algorithm). Also see the [gzip FAQ](http://www.gzip.org/#faq11). In my opinion, if miniz falls prey to a patent attack then zlib/gzip are likely to be at serious risk too. + + +[![Build Status](https://travis-ci.org/uroni/miniz.svg?branch=master)](https://travis-ci.org/uroni/miniz) \ No newline at end of file From 959672230308f2b5b0164ea8e1df124a5ab18aee Mon Sep 17 00:00:00 2001 From: Alessandro Ranellucci Date: Thu, 15 Jul 2021 17:39:27 +0200 Subject: [PATCH 204/209] Fix duplicate symbols caused by double invocation of miniz.h --- xs/src/Zip/ZipArchive.cpp | 1 - 1 file changed, 1 deletion(-) diff --git a/xs/src/Zip/ZipArchive.cpp b/xs/src/Zip/ZipArchive.cpp index 532b2de611..bd2c9c98d0 100644 --- a/xs/src/Zip/ZipArchive.cpp +++ b/xs/src/Zip/ZipArchive.cpp @@ -1,4 +1,3 @@ -#include "miniz/miniz.h" #include "Zip/ZipArchive.hpp" namespace Slic3r { From 8abcb511337468a7bd114edae79c1214e31500fa Mon Sep 17 00:00:00 2001 From: Alessandro Ranellucci Date: Thu, 15 Jul 2021 18:57:40 +0200 Subject: [PATCH 205/209] Bugfix: sending G-code failed because of line number errors. #4847 --- xs/src/libslic3r/GCodeSender.cpp | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/xs/src/libslic3r/GCodeSender.cpp b/xs/src/libslic3r/GCodeSender.cpp index af1f697c9d..0ad3f8cb09 100644 --- a/xs/src/libslic3r/GCodeSender.cpp +++ b/xs/src/libslic3r/GCodeSender.cpp @@ -53,8 +53,8 @@ constexpr auto KEEP_SENT = 20;
