This bug - would only have occurred 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 <time.h> 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 - 5/20/12 v1.14 - MinGW32/64 GCC 4.6.1 compiler fixes: added MZ_FORCEINLINE, - #include <time.h> (thanks fermtect). - 5/19/12 v1.13 - 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. 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 examples so they exit with an error on files which - are too large (a limitation of the examples, not miniz itself). - 4/12/12 v1.12 - More comments, added low-level example5.c, fixed a couple - minor level_and_flags issues in the archive API's. - level_and_flags can now be set to MZ_DEFAULT_COMPRESSION. Thanks to Bruce - Dawson <bruced@valvesoftware.com> 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 <stdlib.h> - -// 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 <time.h> -#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 defined(__sparcv9) -// Big endian -#else -#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 -#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 -#define MINIZ_USE_UNALIGNED_LOADS_AND_STORES \ - 0 // disable to suppress compiler warnings -#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.
