1 /* miniz.c 2.1.0 - public domain deflate/inflate, zlib-subset, ZIP reading/writing/appending, PNG writing 2 See "unlicense" statement at the end of this file. 3 Rich Geldreich <richgel99@gmail.com>, last updated Oct. 13, 2013 4 Implements RFC 1950: http://www.ietf.org/rfc/rfc1950.txt and RFC 1951: http://www.ietf.org/rfc/rfc1951.txt 5 6 Most API's defined in miniz.c are optional. For example, to disable the archive related functions just define 7 MINIZ_NO_ARCHIVE_APIS, or to get rid of all stdio usage define MINIZ_NO_STDIO (see the list below for more macros). 8 9 * Low-level Deflate/Inflate implementation notes: 10 11 Compression: Use the "tdefl" API's. The compressor supports raw, static, and dynamic blocks, lazy or 12 greedy parsing, match length filtering, RLE-only, and Huffman-only streams. It performs and compresses 13 approximately as well as zlib. 14 15 Decompression: Use the "tinfl" API's. The entire decompressor is implemented as a single function 16 coroutine: see tinfl_decompress(). It supports decompression into a 32KB (or larger power of 2) wrapping buffer, or into a memory 17 block large enough to hold the entire file. 18 19 The low-level tdefl/tinfl API's do not make any use of dynamic memory allocation. 20 21 * zlib-style API notes: 22 23 miniz.c implements a fairly large subset of zlib. There's enough functionality present for it to be a drop-in 24 zlib replacement in many apps: 25 The z_stream struct, optional memory allocation callbacks 26 deflateInit/deflateInit2/deflate/deflateReset/deflateEnd/deflateBound 27 inflateInit/inflateInit2/inflate/inflateReset/inflateEnd 28 compress, compress2, compressBound, uncompress 29 CRC-32, Adler-32 - Using modern, minimal code size, CPU cache friendly routines. 30 Supports raw deflate streams or standard zlib streams with adler-32 checking. 31 32 Limitations: 33 The callback API's are not implemented yet. No support for gzip headers or zlib static dictionaries. 34 I've tried to closely emulate zlib's various flavors of stream flushing and return status codes, but 35 there are no guarantees that miniz.c pulls this off perfectly. 36 37 * PNG writing: See the tdefl_write_image_to_png_file_in_memory() function, originally written by 38 Alex Evans. Supports 1-4 bytes/pixel images. 39 40 * ZIP archive API notes: 41 42 The ZIP archive API's where designed with simplicity and efficiency in mind, with just enough abstraction to 43 get the job done with minimal fuss. There are simple API's to retrieve file information, read files from 44 existing archives, create new archives, append new files to existing archives, or clone archive data from 45 one archive to another. It supports archives located in memory or the heap, on disk (using stdio.h), 46 or you can specify custom file read/write callbacks. 47 48 - Archive reading: Just call this function to read a single file from a disk archive: 49 50 void *mz_zip_extract_archive_file_to_heap(const char *pZip_filename, const char *pArchive_name, 51 size_t *pSize, mz_uint zip_flags); 52 53 For more complex cases, use the "mz_zip_reader" functions. Upon opening an archive, the entire central 54 directory is located and read as-is into memory, and subsequent file access only occurs when reading individual files. 55 56 - Archives file scanning: The simple way is to use this function to scan a loaded archive for a specific file: 57 58 int mz_zip_reader_locate_file(mz_zip_archive *pZip, const char *pName, const char *pComment, mz_uint flags); 59 60 The locate operation can optionally check file comments too, which (as one example) can be used to identify 61 multiple versions of the same file in an archive. This function uses a simple linear search through the central 62 directory, so it's not very fast. 63 64 Alternately, you can iterate through all the files in an archive (using mz_zip_reader_get_num_files()) and 65 retrieve detailed info on each file by calling mz_zip_reader_file_stat(). 66 67 - Archive creation: Use the "mz_zip_writer" functions. The ZIP writer immediately writes compressed file data 68 to disk and builds an exact image of the central directory in memory. The central directory image is written 69 all at once at the end of the archive file when the archive is finalized. 70 71 The archive writer can optionally align each file's local header and file data to any power of 2 alignment, 72 which can be useful when the archive will be read from optical media. Also, the writer supports placing 73 arbitrary data blobs at the very beginning of ZIP archives. Archives written using either feature are still 74 readable by any ZIP tool. 75 76 - Archive appending: The simple way to add a single file to an archive is to call this function: 77 78 mz_bool mz_zip_add_mem_to_archive_file_in_place(const char *pZip_filename, const char *pArchive_name, 79 const void *pBuf, size_t buf_size, const void *pComment, mz_uint16 comment_size, mz_uint level_and_flags); 80 81 The archive will be created if it doesn't already exist, otherwise it'll be appended to. 82 Note the appending is done in-place and is not an atomic operation, so if something goes wrong 83 during the operation it's possible the archive could be left without a central directory (although the local 84 file headers and file data will be fine, so the archive will be recoverable). 85 86 For more complex archive modification scenarios: 87 1. The safest way is to use a mz_zip_reader to read the existing archive, cloning only those bits you want to 88 preserve into a new archive using using the mz_zip_writer_add_from_zip_reader() function (which compiles the 89 compressed file data as-is). When you're done, delete the old archive and rename the newly written archive, and 90 you're done. This is safe but requires a bunch of temporary disk space or heap memory. 91 92 2. Or, you can convert an mz_zip_reader in-place to an mz_zip_writer using mz_zip_writer_init_from_reader(), 93 append new files as needed, then finalize the archive which will write an updated central directory to the 94 original archive. (This is basically what mz_zip_add_mem_to_archive_file_in_place() does.) There's a 95 possibility that the archive's central directory could be lost with this method if anything goes wrong, though. 96 97 - ZIP archive support limitations: 98 No zip64 or spanning support. Extraction functions can only handle unencrypted, stored or deflated files. 99 Requires streams capable of seeking. 100 101 * This is a header file library, like stb_image.c. To get only a header file, either cut and paste the 102 below header, or create miniz.h, #define MINIZ_HEADER_FILE_ONLY, and then include miniz.c from it. 103 104 * Important: For best perf. be sure to customize the below macros for your target platform: 105 #define MINIZ_USE_UNALIGNED_LOADS_AND_STORES 1 106 #define MINIZ_LITTLE_ENDIAN 1 107 #define MINIZ_HAS_64BIT_REGISTERS 1 108 109 * On platforms using glibc, Be sure to "#define _LARGEFILE64_SOURCE 1" before including miniz.c to ensure miniz 110 uses the 64-bit variants: fopen64(), stat64(), etc. Otherwise you won't be able to process large files 111 (i.e. 32-bit stat() fails for me on files > 0x7FFFFFFF bytes). 112 */ 113 #pragma once 114 115 #include "miniz_common.h" 116 #include "miniz_tdef.h" 117 #include "miniz_tinfl.h" 118 119 /* Defines to completely disable specific portions of miniz.c: 120 If all macros here are defined the only functionality remaining will be CRC-32, adler-32, tinfl, and tdefl. */ 121 122 /* Define MINIZ_NO_STDIO to disable all usage and any functions which rely on stdio for file I/O. */ 123 /*#define MINIZ_NO_STDIO */ 124 125 /* If MINIZ_NO_TIME is specified then the ZIP archive functions will not be able to get the current time, or */ 126 /* get/set file times, and the C run-time funcs that get/set times won't be called. */ 127 /* The current downside is the times written to your archives will be from 1979. */ 128 /*#define MINIZ_NO_TIME */ 129 130 /* Define MINIZ_NO_ARCHIVE_APIS to disable all ZIP archive API's. */ 131 /*#define MINIZ_NO_ARCHIVE_APIS */ 132 133 /* Define MINIZ_NO_ARCHIVE_WRITING_APIS to disable all writing related ZIP archive API's. */ 134 /*#define MINIZ_NO_ARCHIVE_WRITING_APIS */ 135 136 /* Define MINIZ_NO_ZLIB_APIS to remove all ZLIB-style compression/decompression API's. */ 137 /*#define MINIZ_NO_ZLIB_APIS */ 138 139 /* Define MINIZ_NO_ZLIB_COMPATIBLE_NAME to disable zlib names, to prevent conflicts against stock zlib. */ 140 /*#define MINIZ_NO_ZLIB_COMPATIBLE_NAMES */ 141 142 /* Define MINIZ_NO_MALLOC to disable all calls to malloc, free, and realloc. 143 Note if MINIZ_NO_MALLOC is defined then the user must always provide custom user alloc/free/realloc 144 callbacks to the zlib and archive API's, and a few stand-alone helper API's which don't provide custom user 145 functions (such as tdefl_compress_mem_to_heap() and tinfl_decompress_mem_to_heap()) won't work. */ 146 /*#define MINIZ_NO_MALLOC */ 147 148 #if defined(__TINYC__) && (defined(__linux) || defined(__linux__)) 149 /* TODO: Work around "error: include file 'sys\utime.h' when compiling with tcc on Linux */ 150 #define MINIZ_NO_TIME 151 #endif 152 153 #include <stddef.h> 154 155 #if !defined(MINIZ_NO_TIME) && !defined(MINIZ_NO_ARCHIVE_APIS) 156 #include <time.h> 157 #endif 158 159 #if defined(_M_IX86) || defined(_M_X64) || defined(__i386__) || defined(__i386) || defined(__i486__) || defined(__i486) || defined(i386) || defined(__ia64__) || defined(__x86_64__) 160 /* MINIZ_X86_OR_X64_CPU is only used to help set the below macros. */ 161 #define MINIZ_X86_OR_X64_CPU 1 162 #else 163 #define MINIZ_X86_OR_X64_CPU 0 164 #endif 165 166 #if (__BYTE_ORDER__ == __ORDER_LITTLE_ENDIAN__) || MINIZ_X86_OR_X64_CPU 167 /* Set MINIZ_LITTLE_ENDIAN to 1 if the processor is little endian. */ 168 #define MINIZ_LITTLE_ENDIAN 1 169 #else 170 #define MINIZ_LITTLE_ENDIAN 0 171 #endif 172 173 /* Set MINIZ_USE_UNALIGNED_LOADS_AND_STORES only if not set */ 174 #if !defined(MINIZ_USE_UNALIGNED_LOADS_AND_STORES) 175 #if MINIZ_X86_OR_X64_CPU 176 /* Set MINIZ_USE_UNALIGNED_LOADS_AND_STORES to 1 on CPU's that permit efficient integer loads and stores from unaligned addresses. */ 177 #define MINIZ_USE_UNALIGNED_LOADS_AND_STORES 1 178 #define MINIZ_UNALIGNED_USE_MEMCPY 179 #else 180 #define MINIZ_USE_UNALIGNED_LOADS_AND_STORES 0 181 #endif 182 #endif 183 184 #if defined(_M_X64) || defined(_WIN64) || defined(__MINGW64__) || defined(_LP64) || defined(__LP64__) || defined(__ia64__) || defined(__x86_64__) 185 /* 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). */ 186 #define MINIZ_HAS_64BIT_REGISTERS 1 187 #else 188 #define MINIZ_HAS_64BIT_REGISTERS 0 189 #endif 190 191 #ifdef __cplusplus 192 extern "C" { 193 #endif 194 195 /* ------------------- zlib-style API Definitions. */ 196 197 /* For more compatibility with zlib, miniz.c uses unsigned long for some parameters/struct members.
