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).

9  * Change History
10  10/19/13 v1.16 beta r1 - Two key inflator-only robustness and streaming related changes. Also merged in tdefl_compressor_alloc(), tdefl_compressor_free() helpers to make script bindings easier for rustyzip.
11  - The inflator coroutine func. is subtle and complex so I'm being cautious about this release. I would greatly appreciate any help with testing or any feedback.
12  I feel good about these changes, and they've been through several hours of automated testing, but they will probably not fix anything for the majority of prev. users so I'm
13  going to mark this release as beta for a few weeks and continue testing it at work/home on various things.
14  - The inflator in raw (non-zlib) mode is now usable on gzip or similiar data streams that have a bunch of bytes following the raw deflate data (problem discovered by rustyzip author williamw520).
15  This version should *never* read beyond the last byte of the raw deflate data independent of how many bytes you pass into the input buffer. This issue was caused by the various Huffman bitbuffer lookahead optimizations, and
16  would not be an issue if the caller knew and enforced the precise size of the raw compressed data *or* if the compressed data was in zlib format (i.e. always followed by the byte aligned zlib adler32).
17  So in other words, you can now call the inflator on deflate streams that are followed by arbitrary amounts of data and it's guaranteed that decompression will stop exactly on the last byte.
18  - The inflator now has a new failure status: TINFL_STATUS_FAILED_CANNOT_MAKE_PROGRESS (-4). Previously, if the inflator was starved of bytes and could not make progress (because the input buffer was empty and the
19  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.
20  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. If the caller didn't know when to stop accepting output
21  (because it didn't know how much uncompressed data was expected, or didn't enforce a sane maximum) it could continue forever. v1.16 cannot fall into this failure mode, instead it'll return
22  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. This is a "soft"
23  failure, so you can call the inflator again with more input and it will try to continue, or you can give up and fail. This could be very useful in network streaming scenarios.
24  - Added documentation to all the tinfl return status codes, fixed miniz_tester so it accepts double minus params for Linux, tweaked example1.c, added a simple "follower bytes" test to miniz_tester.cpp.
25  10/13/13 v1.15 r4 - Interim bugfix release while I work on the next major release with Zip64 support (almost there!):
26  - 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
27  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()
28  (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).
29  - 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
30  - 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.
31  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).
32  - Fixing mz_zip_reader_is_file_a_directory() so it doesn't check the internal attributes, just the filename and external attributes
33  - mz_zip_reader_init_file() - missing MZ_FCLOSE() call if the seek failed
34  - Added cmake support for Linux builds which builds all the examples, tested with clang v3.3 and gcc v4.6.
35  - Clang fix for tdefl_write_image_to_png_file_in_memory() from toffaletti
36  - Merged MZ_FORCEINLINE fix from hdeanclark
37  - Fix <time.h> include before config #ifdef, thanks emil.brink
38  - 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
39  set it to 1 for real-time compression).
40  - Merged in some compiler fixes from paulharris's github repro.
41  - Retested this build under Windows (VS 2010, including static analysis), tcc 0.9.26, gcc v4.6 and clang v3.3.
42  - Added example6.c, which dumps an image of the mandelbrot set to a PNG file.
43  - Modified example2 to help test the MZ_ZIP_FLAG_DO_NOT_SORT_CENTRAL_DIRECTORY flag more.
44  - 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
45  - 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
46  5/20/12 v1.14 - MinGW32/64 GCC 4.6.1 compiler fixes: added MZ_FORCEINLINE, #include <time.h> (thanks fermtect).
47  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.
48  - Temporarily/locally slammed in "typedef unsigned long mz_ulong" and re-ran a randomized regression test on ~500k files.
49  - Eliminated a bunch of warnings when compiling with GCC 32-bit/64.
50  - Ran all examples, miniz.c, and tinfl.c through MSVC 2008's /analyze (static analysis) option and fixed all warnings (except for the silly
51  "Use of the comma-operator in a tested expression.." analysis warning, which I purposely use to work around a MSVC compiler warning).
52  - Created 32-bit and 64-bit Codeblocks projects/workspace. Built and tested Linux executables. The codeblocks workspace is compatible with Linux+Win32/x64.
53  - 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.
54  - Ran miniz.c and tinfl.c through another series of regression testing on ~500,000 files and archives.
55  - 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.)
56  - 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).
57  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.
58  level_and_flags can now be set to MZ_DEFAULT_COMPRESSION. Thanks to Bruce Dawson <bruced@valvesoftware.com> for the feedback/bug report.
59  5/28/11 v1.11 - Added statement from unlicense.org
60  5/27/11 v1.10 - Substantial compressor optimizations:
61  - Level 1 is now ~4x faster than before. The L1 compressor's throughput now varies between 70-110MB/sec. on a
62  - Core i7 (actual throughput varies depending on the type of data, and x64 vs. x86).
63  - Improved baseline L2-L9 compression perf. Also, greatly improved compression perf. issues on some file types.
64  - Refactored the compression code for better readability and maintainability.
65  - Added level 10 compression level (L10 has slightly better ratio than level 9, but could have a potentially large
66  drop in throughput on some files).
67  5/15/11 v1.09 - Initial stable release.
68 
69  * Low-level Deflate/Inflate implementation notes:
70 
71  Compression: Use the "tdefl" API's. The compressor supports raw, static, and dynamic blocks, lazy or
72  greedy parsing, match length filtering, RLE-only, and Huffman-only streams. It performs and compresses
73  approximately as well as zlib.
74 
75  Decompression: Use the "tinfl" API's. The entire decompressor is implemented as a single function
76  coroutine: see tinfl_decompress(). It supports decompression into a 32KB (or larger power of 2) wrapping buffer, or into a memory
77  block large enough to hold the entire file.
78 
79  The low-level tdefl/tinfl API's do not make any use of dynamic memory allocation.
80 
81  * zlib-style API notes:
82 
83  miniz.c implements a fairly large subset of zlib. There's enough functionality present for it to be a drop-in
84  zlib replacement in many apps:
85  The z_stream struct, optional memory allocation callbacks
86  deflateInit/deflateInit2/deflate/deflateReset/deflateEnd/deflateBound
87  inflateInit/inflateInit2/inflate/inflateEnd
88  compress, compress2, compressBound, uncompress
89  CRC-32, Adler-32 - Using modern, minimal code size, CPU cache friendly routines.
90  Supports raw deflate streams or standard zlib streams with adler-32 checking.
91 
92  Limitations:
93  The callback API's are not implemented yet. No support for gzip headers or zlib static dictionaries.
94  I've tried to closely emulate zlib's various flavors of stream flushing and return status codes, but
95  there are no guarantees that miniz.c pulls this off perfectly.
96 
97  * PNG writing: See the tdefl_write_image_to_png_file_in_memory() function, originally written by
98  Alex Evans. Supports 1-4 bytes/pixel images.
99 
100  * ZIP archive API notes:
101 
102  The ZIP archive API's where designed with simplicity and efficiency in mind, with just enough abstraction to
103  get the job done with minimal fuss. There are simple API's to retrieve file information, read files from
104  existing archives, create new archives, append new files to existing archives, or clone archive data from
105  one archive to another. It supports archives located in memory or the heap, on disk (using stdio.h),
106  or you can specify custom file read/write callbacks.
107 
108  - Archive reading: Just call this function to read a single file from a disk archive:
109 
110  void *mz_zip_extract_archive_file_to_heap(const char *pZip_filename, const char *pArchive_name,
111  size_t *pSize, mz_uint zip_flags);
112 
113  For more complex cases, use the "mz_zip_reader" functions. Upon opening an archive, the entire central
114  directory is located and read as-is into memory, and subsequent file access only occurs when reading individual files.
115 
116  - Archives file scanning: The simple way is to use this function to scan a loaded archive for a specific file:
117 
118  int mz_zip_reader_locate_file(mz_zip_archive *pZip, const char *pName, const char *pComment, mz_uint flags);
119 
120  The locate operation can optionally check file comments too, which (as one example) can be used to identify
121  multiple versions of the same file in an archive. This function uses a simple linear search through the central
122  directory, so it's not very fast.
123 
124  Alternately, you can iterate through all the files in an archive (using mz_zip_reader_get_num_files()) and
125  retrieve detailed info on each file by calling mz_zip_reader_file_stat().
126 
127  - Archive creation: Use the "mz_zip_writer" functions. The ZIP writer immediately writes compressed file data
128  to disk and builds an exact image of the central directory in memory. The central directory image is written
129  all at once at the end of the archive file when the archive is finalized.
130 
131  The archive writer can optionally align each file's local header and file data to any power of 2 alignment,
132  which can be useful when the archive will be read from optical media. Also, the writer supports placing
133  arbitrary data blobs at the very beginning of ZIP archives. Archives written using either feature are still
134  readable by any ZIP tool.
135 
136  - Archive appending: The simple way to add a single file to an archive is to call this function:
137 
138  mz_bool mz_zip_add_mem_to_archive_file_in_place(const char *pZip_filename, const char *pArchive_name,
139  const void *pBuf, size_t buf_size, const void *pComment, mz_uint16 comment_size, mz_uint level_and_flags);
140 
141  The archive will be created if it doesn't already exist, otherwise it'll be appended to.
142  Note the appending is done in-place and is not an atomic operation, so if something goes wrong
143  during the operation it's possible the archive could be left without a central directory (although the local
144  file headers and file data will be fine, so the archive will be recoverable).
145 
146  For more complex archive modification scenarios:
147  1. The safest way is to use a mz_zip_reader to read the existing archive, cloning only those bits you want to
148  preserve into a new archive using using the mz_zip_writer_add_from_zip_reader() function (which compiles the
149  compressed file data as-is). When you're done, delete the old archive and rename the newly written archive, and
150  you're done. This is safe but requires a bunch of temporary disk space or heap memory.
151 
152  2. Or, you can convert an mz_zip_reader in-place to an mz_zip_writer using mz_zip_writer_init_from_reader(),
153  append new files as needed, then finalize the archive which will write an updated central directory to the
154  original archive. (This is basically what mz_zip_add_mem_to_archive_file_in_place() does.) There's a
155  possibility that the archive's central directory could be lost with this method if anything goes wrong, though.
156 
157  - ZIP archive support limitations:
158  No zip64 or spanning support. Extraction functions can only handle unencrypted, stored or deflated files.
159  Requires streams capable of seeking.
160 
161  * This is a header file library, like stb_image.c. To get only a header file, either cut and paste the
162  below header, or create miniz.h, #define MINIZ_HEADER_FILE_ONLY, and then include miniz.c from it.
163 
164  * Important: For best perf. be sure to customize the below macros for your target platform:
165  #define MINIZ_USE_UNALIGNED_LOADS_AND_STORES 1
166  #define MINIZ_LITTLE_ENDIAN 1
167  #define MINIZ_HAS_64BIT_REGISTERS 1
168 
169  * On platforms using glibc, Be sure to "#define _LARGEFILE64_SOURCE 1" before including miniz.c to ensure miniz
170  uses the 64-bit variants: fopen64(), stat64(), etc. Otherwise you won't be able to process large files
171  (i.e. 32-bit stat() fails for me on files > 0x7FFFFFFF bytes).
