## [Unreleased][unreleased]
+
+### Changed
+- Changed `hf 14b write` to `hf 14b sriwrite` as it only applied to sri tags (marshmellow)
+- Added `hf 14b info` to `hf search` (marshmellow)
+
+### Added
+- Add `hf 14b info` to find and print info about std 14b tags and sri tags (using 14b raw commands in the client) (marshmellow)
+- Add PACE replay functionality (frederikmoellers)
+
+### Fixed
+- t55xx write timing (marshmellow)
+
+
+## [2.1.0][2015-06-23]
+
### Changed
+- Added ultralight/ntag tag type detection to `hf 14a read` (marshmellow)
+- Improved ultralight dump command to auto detect tag type, take authentication, and dump full memory (or subset specified) of known tag types (iceman1001 / marshmellow)
+- Combined ultralight read/write commands and added authentication (iceman1001)
+- Improved LF manchester and biphase demodulation and ask clock detection especially for reads with heavy clipping. (marshmellow)
- Iclass read, `hf iclass read` now also reads tag config and prints configuration. (holiman)
+- *bootrom* needs to be flashed, due to new address boundaries between os and fpga, after a size optimization (piwi)
### Fixed
-- Fixed issue #19, problems with LF T55xx commands (marshmellow)
+- Fixed EM4x50 read/demod of the tags broadcasted memory blocks. 'lf em4x em4x50read' (not page read) (marshmellow)
+- Fixed issue #19, problems with LF T55xx commands (iceman1001, marshmellow)
+- Fixed various problems with iso14443b, issue #103 (piwi, marshmellow)
### Added
+- Added `hf search` - currently tests for 14443a tags, iclass tags, and 15693 tags (marshmellow)
+- Added `hf mfu info` Ultralight/NTAG info command - reads tag configuration and info, allows authentication if needed (iceman1001, marshmellow)
+- Added Mifare Ultralight C and Ultralight EV1/NTAG authentication. (iceman1001)

============
-macport stuff should do ;)
+Tested on OSX 10.10 Yosemite
+
+1 - Install Xcode and Xcode Command Line Tools
+
+2 - Install Homebrew and dependencies
+ brew install readline
+ brew instal libusb
+
+3 - Download DevKitARM for OSX
+ http://sourceforge.net/projects/devkitpro/files/devkitARM/devkitARM_r44/
+ Unpack devkitARM_r44-osx.tar.bz2 to proxmark3 directory.
+
+4 - Edit proxmark3/client/Makefile adding path to readline
+
+ LDLIBS = -L/usr/local/Cellar/readline/6.3.8/lib/ -L/opt/local/lib -L/usr/local/lib ../liblua/liblua.a -lreadline -lpthread -lm
+ CFLAGS = -std=c99 -I/usr/local/Cellar/readline/6.3.8/include/ -I. -I../include -I../common -I/opt/local/include -I../liblua -Wall $(COMMON_FLAGS) -g -O4
+
+ Replace path /usr/local/Cellar/readline/6.3.8 with your actuall readline path. See homebrew manuals.
+
+5 - Set Environment
+
+ export DEVKITPRO=$HOME/proxmark3/
+ export DEVKITARM=$DEVKITPRO/devkitARM
+ export PATH=${PATH}:${DEVKITARM}/bin

+
+ Frequently Asked Questions about zlib
+
+
+If your question is not there, please check the zlib home page
+http://zlib.net/ which may have more recent information.
+The lastest zlib FAQ is at http://zlib.net/zlib_faq.html
+
+
+ 1. Is zlib Y2K-compliant?
+
+ Yes. zlib doesn't handle dates.
+
+ 2. Where can I get a Windows DLL version?
+
+ The zlib sources can be compiled without change to produce a DLL. See the
+ file win32/DLL_FAQ.txt in the zlib distribution. Pointers to the
+ precompiled DLL are found in the zlib web site at http://zlib.net/ .
+
+ 3. Where can I get a Visual Basic interface to zlib?
+
+ See
+ * http://marknelson.us/1997/01/01/zlib-engine/
+ * win32/DLL_FAQ.txt in the zlib distribution
+
+ 4. compress() returns Z_BUF_ERROR.
+
+ Make sure that before the call of compress(), the length of the compressed
+ buffer is equal to the available size of the compressed buffer and not
+ zero. For Visual Basic, check that this parameter is passed by reference
+ ("as any"), not by value ("as long").
+
+ 5. deflate() or inflate() returns Z_BUF_ERROR.
+
+ Before making the call, make sure that avail_in and avail_out are not zero.
+ When setting the parameter flush equal to Z_FINISH, also make sure that
+ avail_out is big enough to allow processing all pending input. Note that a
+ Z_BUF_ERROR is not fatal--another call to deflate() or inflate() can be
+ made with more input or output space. A Z_BUF_ERROR may in fact be
+ unavoidable depending on how the functions are used, since it is not
+ possible to tell whether or not there is more output pending when
+ strm.avail_out returns with zero. See http://zlib.net/zlib_how.html for a
+ heavily annotated example.
+
+ 6. Where's the zlib documentation (man pages, etc.)?
+
+ It's in zlib.h . Examples of zlib usage are in the files test/example.c
+ and test/minigzip.c, with more in examples/ .
+
+ 7. Why don't you use GNU autoconf or libtool or ...?
+
+ Because we would like to keep zlib as a very small and simple package.
+ zlib is rather portable and doesn't need much configuration.
+
+ 8. I found a bug in zlib.
+
+ Most of the time, such problems are due to an incorrect usage of zlib.
+ Please try to reproduce the problem with a small program and send the
+ corresponding source to us at zlib@gzip.org . Do not send multi-megabyte
+ data files without prior agreement.
+
+ 9. Why do I get "undefined reference to gzputc"?
+
+ If "make test" produces something like
+
+ example.o(.text+0x154): undefined reference to `gzputc'
+
+ check that you don't have old files libz.* in /usr/lib, /usr/local/lib or
+ /usr/X11R6/lib. Remove any old versions, then do "make install".
+
+10. I need a Delphi interface to zlib.
+
+ See the contrib/delphi directory in the zlib distribution.
+
+11. Can zlib handle .zip archives?
+
+ Not by itself, no. See the directory contrib/minizip in the zlib
+ distribution.
+
+12. Can zlib handle .Z files?
+
+ No, sorry. You have to spawn an uncompress or gunzip subprocess, or adapt
+ the code of uncompress on your own.
+
+13. How can I make a Unix shared library?
+
+ By default a shared (and a static) library is built for Unix. So:
+
+ make distclean
+ ./configure
+ make
+
+14. How do I install a shared zlib library on Unix?
+
+ After the above, then:
+
+ make install
+
+ However, many flavors of Unix come with a shared zlib already installed.
+ Before going to the trouble of compiling a shared version of zlib and
+ trying to install it, you may want to check if it's already there! If you
+ can #include <zlib.h>, it's there. The -lz option will probably link to
+ it. You can check the version at the top of zlib.h or with the
+ ZLIB_VERSION symbol defined in zlib.h .
+
+15. I have a question about OttoPDF.
+
+ We are not the authors of OttoPDF. The real author is on the OttoPDF web
+ site: Joel Hainley, jhainley@myndkryme.com.
+
+16. Can zlib decode Flate data in an Adobe PDF file?
+
+ Yes. See http://www.pdflib.com/ . To modify PDF forms, see
+ http://sourceforge.net/projects/acroformtool/ .
+
+17. Why am I getting this "register_frame_info not found" error on Solaris?
+
+ After installing zlib 1.1.4 on Solaris 2.6, running applications using zlib
+ generates an error such as:
+
+ ld.so.1: rpm: fatal: relocation error: file /usr/local/lib/libz.so:
+ symbol __register_frame_info: referenced symbol not found
+
+ The symbol __register_frame_info is not part of zlib, it is generated by
+ the C compiler (cc or gcc). You must recompile applications using zlib
+ which have this problem. This problem is specific to Solaris. See
+ http://www.sunfreeware.com for Solaris versions of zlib and applications
+ using zlib.
+
+18. Why does gzip give an error on a file I make with compress/deflate?
+
+ The compress and deflate functions produce data in the zlib format, which
+ is different and incompatible with the gzip format. The gz* functions in
+ zlib on the other hand use the gzip format. Both the zlib and gzip formats
+ use the same compressed data format internally, but have different headers
+ and trailers around the compressed data.
+
+19. Ok, so why are there two different formats?
+
+ The gzip format was designed to retain the directory information about a
+ single file, such as the name and last modification date. The zlib format
+ on the other hand was designed for in-memory and communication channel
+ applications, and has a much more compact header and trailer and uses a
+ faster integrity check than gzip.
+
+20. Well that's nice, but how do I make a gzip file in memory?
+
+ You can request that deflate write the gzip format instead of the zlib
+ format using deflateInit2(). You can also request that inflate decode the
+ gzip format using inflateInit2(). Read zlib.h for more details.
+
+21. Is zlib thread-safe?
+
+ Yes. However any library routines that zlib uses and any application-
+ provided memory allocation routines must also be thread-safe. zlib's gz*
+ functions use stdio library routines, and most of zlib's functions use the
+ library memory allocation routines by default. zlib's *Init* functions
+ allow for the application to provide custom memory allocation routines.
+
+ Of course, you should only operate on any given zlib or gzip stream from a
+ single thread at a time.
+
+22. Can I use zlib in my commercial application?
+
+ Yes. Please read the license in zlib.h.
+
+23. Is zlib under the GNU license?
+
+ No. Please read the license in zlib.h.
+
+24. The license says that altered source versions must be "plainly marked". So
+ what exactly do I need to do to meet that requirement?
+
+ You need to change the ZLIB_VERSION and ZLIB_VERNUM #defines in zlib.h. In
+ particular, the final version number needs to be changed to "f", and an
+ identification string should be appended to ZLIB_VERSION. Version numbers
+ x.x.x.f are reserved for modifications to zlib by others than the zlib
+ maintainers. For example, if the version of the base zlib you are altering
+ is "1.2.3.4", then in zlib.h you should change ZLIB_VERNUM to 0x123f, and
+ ZLIB_VERSION to something like "1.2.3.f-zachary-mods-v3". You can also
+ update the version strings in deflate.c and inftrees.c.
+
+ For altered source distributions, you should also note the origin and
+ nature of the changes in zlib.h, as well as in ChangeLog and README, along
+ with the dates of the alterations. The origin should include at least your
+ name (or your company's name), and an email address to contact for help or
+ issues with the library.
+
+ Note that distributing a compiled zlib library along with zlib.h and
+ zconf.h is also a source distribution, and so you should change
+ ZLIB_VERSION and ZLIB_VERNUM and note the origin and nature of the changes
+ in zlib.h as you would for a full source distribution.
+
+25. Will zlib work on a big-endian or little-endian architecture, and can I
+ exchange compressed data between them?
+
+ Yes and yes.
+
+26. Will zlib work on a 64-bit machine?
+
+ Yes. It has been tested on 64-bit machines, and has no dependence on any
+ data types being limited to 32-bits in length. If you have any
+ difficulties, please provide a complete problem report to zlib@gzip.org
+
+27. Will zlib decompress data from the PKWare Data Compression Library?
+
+ No. The PKWare DCL uses a completely different compressed data format than
+ does PKZIP and zlib. However, you can look in zlib's contrib/blast
+ directory for a possible solution to your problem.
+
+28. Can I access data randomly in a compressed stream?
+
+ No, not without some preparation. If when compressing you periodically use
+ Z_FULL_FLUSH, carefully write all the pending data at those points, and
+ keep an index of those locations, then you can start decompression at those
+ points. You have to be careful to not use Z_FULL_FLUSH too often, since it
+ can significantly degrade compression. Alternatively, you can scan a
+ deflate stream once to generate an index, and then use that index for
+ random access. See examples/zran.c .
+
+29. Does zlib work on MVS, OS/390, CICS, etc.?
+
+ It has in the past, but we have not heard of any recent evidence. There
+ were working ports of zlib 1.1.4 to MVS, but those links no longer work.
+ If you know of recent, successful applications of zlib on these operating
+ systems, please let us know. Thanks.
+
+30. Is there some simpler, easier to read version of inflate I can look at to
+ understand the deflate format?
+
+ First off, you should read RFC 1951. Second, yes. Look in zlib's
+ contrib/puff directory.
+
+31. Does zlib infringe on any patents?
+
+ As far as we know, no. In fact, that was originally the whole point behind
+ zlib. Look here for some more information:
+
+ http://www.gzip.org/#faq11
+
+32. Can zlib work with greater than 4 GB of data?
+
+ Yes. inflate() and deflate() will process any amount of data correctly.
+ Each call of inflate() or deflate() is limited to input and output chunks
+ of the maximum value that can be stored in the compiler's "unsigned int"
+ type, but there is no limit to the number of chunks. Note however that the
+ strm.total_in and strm_total_out counters may be limited to 4 GB. These
+ counters are provided as a convenience and are not used internally by
+ inflate() or deflate(). The application can easily set up its own counters
+ updated after each call of inflate() or deflate() to count beyond 4 GB.
+ compress() and uncompress() may be limited to 4 GB, since they operate in a
+ single call. gzseek() and gztell() may be limited to 4 GB depending on how
+ zlib is compiled. See the zlibCompileFlags() function in zlib.h.
+
+ The word "may" appears several times above since there is a 4 GB limit only
+ if the compiler's "long" type is 32 bits. If the compiler's "long" type is
+ 64 bits, then the limit is 16 exabytes.
+
+33. Does zlib have any security vulnerabilities?
+
+ The only one that we are aware of is potentially in gzprintf(). If zlib is
+ compiled to use sprintf() or vsprintf(), then there is no protection
+ against a buffer overflow of an 8K string space (or other value as set by
+ gzbuffer()), other than the caller of gzprintf() assuring that the output
+ will not exceed 8K. On the other hand, if zlib is compiled to use
+ snprintf() or vsnprintf(), which should normally be the case, then there is
+ no vulnerability. The ./configure script will display warnings if an
+ insecure variation of sprintf() will be used by gzprintf(). Also the
+ zlibCompileFlags() function will return information on what variant of
+ sprintf() is used by gzprintf().
+
+ If you don't have snprintf() or vsnprintf() and would like one, you can
+ find a portable implementation here:
+
+ http://www.ijs.si/software/snprintf/
+
+ Note that you should be using the most recent version of zlib. Versions
+ 1.1.3 and before were subject to a double-free vulnerability, and versions
+ 1.2.1 and 1.2.2 were subject to an access exception when decompressing
+ invalid compressed data.
+
+34. Is there a Java version of zlib?
+
+ Probably what you want is to use zlib in Java. zlib is already included
+ as part of the Java SDK in the java.util.zip package. If you really want
+ a version of zlib written in the Java language, look on the zlib home
+ page for links: http://zlib.net/ .
+
+35. I get this or that compiler or source-code scanner warning when I crank it
+ up to maximally-pedantic. Can't you guys write proper code?
+
+ Many years ago, we gave up attempting to avoid warnings on every compiler
+ in the universe. It just got to be a waste of time, and some compilers
+ were downright silly as well as contradicted each other. So now, we simply
+ make sure that the code always works.
+
+36. Valgrind (or some similar memory access checker) says that deflate is
+ performing a conditional jump that depends on an uninitialized value.
+ Isn't that a bug?
+
+ No. That is intentional for performance reasons, and the output of deflate
+ is not affected. This only started showing up recently since zlib 1.2.x
+ uses malloc() by default for allocations, whereas earlier versions used
+ calloc(), which zeros out the allocated memory. Even though the code was
+ correct, versions 1.2.4 and later was changed to not stimulate these
+ checkers.
+
+37. Will zlib read the (insert any ancient or arcane format here) compressed
+ data format?
+
+ Probably not. Look in the comp.compression FAQ for pointers to various
+ formats and associated software.
+
+38. How can I encrypt/decrypt zip files with zlib?
+
+ zlib doesn't support encryption. The original PKZIP encryption is very
+ weak and can be broken with freely available programs. To get strong
+ encryption, use GnuPG, http://www.gnupg.org/ , which already includes zlib
+ compression. For PKZIP compatible "encryption", look at
+ http://www.info-zip.org/
+
+39. What's the difference between the "gzip" and "deflate" HTTP 1.1 encodings?
+
+ "gzip" is the gzip format, and "deflate" is the zlib format. They should
+ probably have called the second one "zlib" instead to avoid confusion with
+ the raw deflate compressed data format. While the HTTP 1.1 RFC 2616
+ correctly points to the zlib specification in RFC 1950 for the "deflate"
+ transfer encoding, there have been reports of servers and browsers that
+ incorrectly produce or expect raw deflate data per the deflate
+ specification in RFC 1951, most notably Microsoft. So even though the
+ "deflate" transfer encoding using the zlib format would be the more
+ efficient approach (and in fact exactly what the zlib format was designed
+ for), using the "gzip" transfer encoding is probably more reliable due to
+ an unfortunate choice of name on the part of the HTTP 1.1 authors.
+
+ Bottom line: use the gzip format for HTTP 1.1 encoding.
+
+40. Does zlib support the new "Deflate64" format introduced by PKWare?
+
+ No. PKWare has apparently decided to keep that format proprietary, since
+ they have not documented it as they have previous compression formats. In
+ any case, the compression improvements are so modest compared to other more
+ modern approaches, that it's not worth the effort to implement.
+
+41. I'm having a problem with the zip functions in zlib, can you help?
+
+ There are no zip functions in zlib. You are probably using minizip by
+ Giles Vollant, which is found in the contrib directory of zlib. It is not
+ part of zlib. In fact none of the stuff in contrib is part of zlib. The
+ files in there are not supported by the zlib authors. You need to contact
+ the authors of the respective contribution for help.
+
+42. The match.asm code in contrib is under the GNU General Public License.
+ Since it's part of zlib, doesn't that mean that all of zlib falls under the
+ GNU GPL?
+
+ No. The files in contrib are not part of zlib. They were contributed by
+ other authors and are provided as a convenience to the user within the zlib
+ distribution. Each item in contrib has its own license.
+
+43. Is zlib subject to export controls? What is its ECCN?
+
+ zlib is not subject to export controls, and so is classified as EAR99.
+
+44. Can you please sign these lengthy legal documents and fax them back to us
+ so that we can use your software in our product?
+
+ No. Go away. Shoo.

+
+ZLIB DATA COMPRESSION LIBRARY
+
+zlib 1.2.8 is a general purpose data compression library. All the code is
+thread safe. The data format used by the zlib library is described by RFCs
+(Request for Comments) 1950 to 1952 in the files
+http://tools.ietf.org/html/rfc1950 (zlib format), rfc1951 (deflate format) and
+rfc1952 (gzip format).
+
+All functions of the compression library are documented in the file zlib.h
+(volunteer to write man pages welcome, contact zlib@gzip.org). A usage example
+of the library is given in the file test/example.c which also tests that
+the library is working correctly. Another example is given in the file
+test/minigzip.c. The compression library itself is composed of all source
+files in the root directory.
+
+To compile all files and run the test program, follow the instructions given at
+the top of Makefile.in. In short "./configure; make test", and if that goes
+well, "make install" should work for most flavors of Unix. For Windows, use
+one of the special makefiles in win32/ or contrib/vstudio/ . For VMS, use
+make_vms.com.
+
+Questions about zlib should be sent to <zlib@gzip.org>, or to Gilles Vollant
+<info@winimage.com> for the Windows DLL version. The zlib home page is
+http://zlib.net/ . Before reporting a problem, please check this site to
+verify that you have the latest version of zlib; otherwise get the latest
+version and check whether the problem still exists or not.
+
+PLEASE read the zlib FAQ http://zlib.net/zlib_faq.html before asking for help.
+
+Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan. 1997
+issue of Dr. Dobb's Journal; a copy of the article is available at
+http://marknelson.us/1997/01/01/zlib-engine/ .
+
+The changes made in version 1.2.8 are documented in the file ChangeLog.
+
+Unsupported third party contributions are provided in directory contrib/ .
+
+zlib is available in Java using the java.util.zip package, documented at
+http://java.sun.com/developer/technicalArticles/Programming/compression/ .
+
+A Perl interface to zlib written by Paul Marquess <pmqs@cpan.org> is available
+at CPAN (Comprehensive Perl Archive Network) sites, including
+http://search.cpan.org/~pmqs/IO-Compress-Zlib/ .
+
+A Python interface to zlib written by A.M. Kuchling <amk@amk.ca> is
+available in Python 1.5 and later versions, see
+http://docs.python.org/library/zlib.html .
+
+zlib is built into tcl: http://wiki.tcl.tk/4610 .
+
+An experimental package to read and write files in .zip format, written on top
+of zlib by Gilles Vollant <info@winimage.com>, is available in the
+contrib/minizip directory of zlib.
+
+
+Notes for some targets:
+
+- For Windows DLL versions, please see win32/DLL_FAQ.txt
+
+- For 64-bit Irix, deflate.c must be compiled without any optimization. With
+ -O, one libpng test fails. The test works in 32 bit mode (with the -n32
+ compiler flag). The compiler bug has been reported to SGI.
+
+- zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1 it works
+ when compiled with cc.
+
+- On Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1 is
+ necessary to get gzprintf working correctly. This is done by configure.
+
+- zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with
+ other compilers. Use "make test" to check your compiler.
+
+- gzdopen is not supported on RISCOS or BEOS.
+
+- For PalmOs, see http://palmzlib.sourceforge.net/
+

+/*
+ * ALGORITHM
+ *
+ * The "deflation" process depends on being able to identify portions
+ * of the input text which are identical to earlier input (within a
+ * sliding window trailing behind the input currently being processed).
+ *
+ * The most straightforward technique turns out to be the fastest for
+ * most input files: try all possible matches and select the longest.
+ * The key feature of this algorithm is that insertions into the string
+ * dictionary are very simple and thus fast, and deletions are avoided
+ * completely. Insertions are performed at each input character, whereas
+ * string matches are performed only when the previous match ends. So it
+ * is preferable to spend more time in matches to allow very fast string
+ * insertions and avoid deletions. The matching algorithm for small
+ * strings is inspired from that of Rabin & Karp. A brute force approach
+ * is used to find longer strings when a small match has been found.
+ * A similar algorithm is used in comic (by Jan-Mark Wams) and freeze
+ * (by Leonid Broukhis).
+ * A previous version of this file used a more sophisticated algorithm
+ * (by Fiala and Greene) which is guaranteed to run in linear amortized
+ * time, but has a larger average cost, uses more memory and is patented.
+ * However the F&G algorithm may be faster for some highly redundant
+ * files if the parameter max_chain_length (described below) is too large.
+ *
+ * ACKNOWLEDGEMENTS
+ *
+ * The idea of lazy evaluation of matches is due to Jan-Mark Wams, and
+ * I found it in 'freeze' written by Leonid Broukhis.

+ */
+
+/*
+ * Change history:
+ *
+ * 1.2.beta0 24 Nov 2002
+ * - First version -- complete rewrite of inflate to simplify code, avoid
+ * creation of window when not needed, minimize use of window when it is
+ * needed, make inffast.c even faster, implement gzip decoding, and to
+ * improve code readability and style over the previous zlib inflate code
+ *
+ * 1.2.beta1 25 Nov 2002
+ * - Use pointers for available input and output checking in inffast.c
+ * - Remove input and output counters in inffast.c
+ * - Change inffast.c entry and loop from avail_in >= 7 to >= 6
+ * - Remove unnecessary second byte pull from length extra in inffast.c
+ * - Unroll direct copy to three copies per loop in inffast.c
+ *
+ * 1.2.beta2 4 Dec 2002
+ * - Change external routine names to reduce potential conflicts
+ * - Correct filename to inffixed.h for fixed tables in inflate.c
+ * - Make hbuf[] unsigned char to match parameter type in inflate.c
+ * - Change strm->next_out[-state->offset] to *(strm->next_out - state->offset)
+ * to avoid negation problem on Alphas (64 bit) in inflate.c
+ *
+ * 1.2.beta3 22 Dec 2002
+ * - Add comments on state->bits assertion in inffast.c
+ * - Add comments on op field in inftrees.h
+ * - Fix bug in reuse of allocated window after inflateReset()
+ * - Remove bit fields--back to byte structure for speed
+ * - Remove distance extra == 0 check in inflate_fast()--only helps for lengths
+ * - Change post-increments to pre-increments in inflate_fast(), PPC biased?
+ * - Add compile time option, POSTINC, to use post-increments instead (Intel?)
+ * - Make MATCH copy in inflate() much faster for when inflate_fast() not used
+ * - Use local copies of stream next and avail values, as well as local bit
+ * buffer and bit count in inflate()--for speed when inflate_fast() not used
+ *
+ * 1.2.beta4 1 Jan 2003
+ * - Split ptr - 257 statements in inflate_table() to avoid compiler warnings
+ * - Move a comment on output buffer sizes from inffast.c to inflate.c
+ * - Add comments in inffast.c to introduce the inflate_fast() routine
+ * - Rearrange window copies in inflate_fast() for speed and simplification
+ * - Unroll last copy for window match in inflate_fast()
+ * - Use local copies of window variables in inflate_fast() for speed
+ * - Pull out common wnext == 0 case for speed in inflate_fast()
+ * - Make op and len in inflate_fast() unsigned for consistency
+ * - Add FAR to lcode and dcode declarations in inflate_fast()
+ * - Simplified bad distance check in inflate_fast()
+ * - Added inflateBackInit(), inflateBack(), and inflateBackEnd() in new
+ * source file infback.c to provide a call-back interface to inflate for
+ * programs like gzip and unzip -- uses window as output buffer to avoid
+ * window copying
+ *
+ * 1.2.beta5 1 Jan 2003
+ * - Improved inflateBack() interface to allow the caller to provide initial
+ * input in strm.
+ * - Fixed stored blocks bug in inflateBack()
+ *
+ * 1.2.beta6 4 Jan 2003
+ * - Added comments in inffast.c on effectiveness of POSTINC
+ * - Typecasting all around to reduce compiler warnings
+ * - Changed loops from while (1) or do {} while (1) to for (;;), again to
+ * make compilers happy
+ * - Changed type of window in inflateBackInit() to unsigned char *
+ *
+ * 1.2.beta7 27 Jan 2003
+ * - Changed many types to unsigned or unsigned short to avoid warnings
+ * - Added inflateCopy() function
+ *
+ * 1.2.0 9 Mar 2003
+ * - Changed inflateBack() interface to provide separate opaque descriptors
+ * for the in() and out() functions
+ * - Changed inflateBack() argument and in_func typedef to swap the length
+ * and buffer address return values for the input function
+ * - Check next_in and next_out for Z_NULL on entry to inflate()
+ *
+ * The history for versions after 1.2.0 are in ChangeLog in zlib distribution.

+ inflate() uses a state machine to process as much input data and generate as
+ much output data as possible before returning. The state machine is
+ structured roughly as follows:
+
+ for (;;) switch (state) {
+ ...
+ case STATEn:
+ if (not enough input data or output space to make progress)
+ return;
+ ... make progress ...
+ state = STATEm;
+ break;
+ ...
+ }
+
+ so when inflate() is called again, the same case is attempted again, and
+ if the appropriate resources are provided, the machine proceeds to the
+ next state. The NEEDBITS() macro is usually the way the state evaluates
+ whether it can proceed or should return. NEEDBITS() does the return if
+ the requested bits are not available. The typical use of the BITS macros
+ is:
+
+ NEEDBITS(n);
+ ... do something with BITS(n) ...
+ DROPBITS(n);
+
+ where NEEDBITS(n) either returns from inflate() if there isn't enough
+ input left to load n bits into the accumulator, or it continues. BITS(n)
+ gives the low n bits in the accumulator. When done, DROPBITS(n) drops
+ the low n bits off the accumulator. INITBITS() clears the accumulator
+ and sets the number of available bits to zero. BYTEBITS() discards just
+ enough bits to put the accumulator on a byte boundary. After BYTEBITS()
+ and a NEEDBITS(8), then BITS(8) would return the next byte in the stream.
+
+ NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return
+ if there is no input available. The decoding of variable length codes uses
+ PULLBYTE() directly in order to pull just enough bytes to decode the next
+ code, and no more.
+
+ Some states loop until they get enough input, making sure that enough
+ state information is maintained to continue the loop where it left off
+ if NEEDBITS() returns in the loop. For example, want, need, and keep
+ would all have to actually be part of the saved state in case NEEDBITS()
+ returns:
+
+ case STATEw:
+ while (want < need) {
+ NEEDBITS(n);
+ keep[want++] = BITS(n);
+ DROPBITS(n);
+ }
+ state = STATEx;
+ case STATEx:
+
+ As shown above, if the next state is also the next case, then the break
+ is omitted.
+
+ A state may also return if there is not enough output space available to
+ complete that state. Those states are copying stored data, writing a
+ literal byte, and copying a matching string.
+
+ When returning, a "goto inf_leave" is used to update the total counters,
+ update the check value, and determine whether any progress has been made
+ during that inflate() call in order to return the proper return code.
+ Progress is defined as a change in either strm->avail_in or strm->avail_out.
+ When there is a window, goto inf_leave will update the window with the last
+ output written. If a goto inf_leave occurs in the middle of decompression
+ and there is no window currently, goto inf_leave will create one and copy
+ output to the window for the next call of inflate().
+
+ In this implementation, the flush parameter of inflate() only affects the
+ return code (per zlib.h). inflate() always writes as much as possible to
+ strm->next_out, given the space available and the provided input--the effect
+ documented in zlib.h of Z_SYNC_FLUSH. Furthermore, inflate() always defers
+ the allocation of and copying into a sliding window until necessary, which
+ provides the effect documented in zlib.h for Z_FINISH when the entire input
+ stream available. So the only thing the flush parameter actually does is:
+ when flush is set to Z_FINISH, inflate() cannot return Z_OK. Instead it
+ will return Z_BUF_ERROR if it has not reached the end of the stream.

+ Process a set of code lengths to create a canonical Huffman code. The
+ code lengths are lens[0..codes-1]. Each length corresponds to the
+ symbols 0..codes-1. The Huffman code is generated by first sorting the
+ symbols by length from short to long, and retaining the symbol order
+ for codes with equal lengths. Then the code starts with all zero bits
+ for the first code of the shortest length, and the codes are integer
+ increments for the same length, and zeros are appended as the length
+ increases. For the deflate format, these bits are stored backwards
+ from their more natural integer increment ordering, and so when the
+ decoding tables are built in the large loop below, the integer codes
+ are incremented backwards.
+
+ This routine assumes, but does not check, that all of the entries in
+ lens[] are in the range 0..MAXBITS. The caller must assure this.
+ 1..MAXBITS is interpreted as that code length. zero means that that
+ symbol does not occur in this code.
+
+ The codes are sorted by computing a count of codes for each length,
+ creating from that a table of starting indices for each length in the
+ sorted table, and then entering the symbols in order in the sorted
+ table. The sorted table is work[], with that space being provided by
+ the caller.
+
+ The length counts are used for other purposes as well, i.e. finding
+ the minimum and maximum length codes, determining if there are any
+ codes at all, checking for a valid set of lengths, and looking ahead
+ at length counts to determine sub-table sizes when building the

+ The 'zlib' compression library provides in-memory compression and
+ decompression functions, including integrity checks of the uncompressed data.
+ This version of the library supports only one compression method (deflation)
+ but other algorithms will be added later and will have the same stream
+ interface.
+
+ Compression can be done in a single step if the buffers are large enough,
+ or can be done by repeated calls of the compression function. In the latter
+ case, the application must provide more input and/or consume the output
+ (providing more output space) before each call.
+
+ The compressed data format used by default by the in-memory functions is
+ the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
+ around a deflate stream, which is itself documented in RFC 1951.
+
+ The library also supports reading and writing files in gzip (.gz) format
+ with an interface similar to that of stdio using the functions that start
+ with "gz". The gzip format is different from the zlib format. gzip is a
+ gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
+
+ This library can optionally read and write gzip streams in memory as well.
+
+ The zlib format was designed to be compact and fast for use in memory
+ and on communications channels. The gzip format was designed for single-
+ file compression on file systems, has a larger header than zlib to maintain
+ directory information, and uses a different, slower check method than zlib.
+
+ The library does not install any signal handler. The decoder checks
+ the consistency of the compressed data, so the library should never crash
+ even in case of corrupted input.

+ deflate compresses as much data as possible, and stops when the input
+ buffer becomes empty or the output buffer becomes full. It may introduce
+ some output latency (reading input without producing any output) except when
+ forced to flush.
+
+ The detailed semantics are as follows. deflate performs one or both of the
+ following actions:
+
+ - Compress more input starting at next_in and update next_in and avail_in
+ accordingly. If not all input can be processed (because there is not
+ enough room in the output buffer), next_in and avail_in are updated and
+ processing will resume at this point for the next call of deflate().
+
+ - Provide more output starting at next_out and update next_out and avail_out
+ accordingly. This action is forced if the parameter flush is non zero.
+ Forcing flush frequently degrades the compression ratio, so this parameter
+ should be set only when necessary (in interactive applications). Some
+ output may be provided even if flush is not set.
+
+ Before the call of deflate(), the application should ensure that at least
+ one of the actions is possible, by providing more input and/or consuming more
+ output, and updating avail_in or avail_out accordingly; avail_out should
+ never be zero before the call. The application can consume the compressed
+ output when it wants, for example when the output buffer is full (avail_out
+ == 0), or after each call of deflate(). If deflate returns Z_OK and with
+ zero avail_out, it must be called again after making room in the output
+ buffer because there might be more output pending.
+
+ Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
+ decide how much data to accumulate before producing output, in order to
+ maximize compression.
+
+ If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
+ flushed to the output buffer and the output is aligned on a byte boundary, so
+ that the decompressor can get all input data available so far. (In
+ particular avail_in is zero after the call if enough output space has been
+ provided before the call.) Flushing may degrade compression for some
+ compression algorithms and so it should be used only when necessary. This
+ completes the current deflate block and follows it with an empty stored block
+ that is three bits plus filler bits to the next byte, followed by four bytes
+ (00 00 ff ff).
+
+ If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the
+ output buffer, but the output is not aligned to a byte boundary. All of the
+ input data so far will be available to the decompressor, as for Z_SYNC_FLUSH.
+ This completes the current deflate block and follows it with an empty fixed
+ codes block that is 10 bits long. This assures that enough bytes are output
+ in order for the decompressor to finish the block before the empty fixed code
+ block.
+
+ If flush is set to Z_BLOCK, a deflate block is completed and emitted, as
+ for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to
+ seven bits of the current block are held to be written as the next byte after
+ the next deflate block is completed. In this case, the decompressor may not
+ be provided enough bits at this point in order to complete decompression of
+ the data provided so far to the compressor. It may need to wait for the next
+ block to be emitted. This is for advanced applications that need to control
+ the emission of deflate blocks.
+
+ If flush is set to Z_FULL_FLUSH, all output is flushed as with
+ Z_SYNC_FLUSH, and the compression state is reset so that decompression can
+ restart from this point if previous compressed data has been damaged or if
+ random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
+ compression.
+
+ If deflate returns with avail_out == 0, this function must be called again
+ with the same value of the flush parameter and more output space (updated
+ avail_out), until the flush is complete (deflate returns with non-zero
+ avail_out). In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that
+ avail_out is greater than six to avoid repeated flush markers due to
+ avail_out == 0 on return.
+
+ If the parameter flush is set to Z_FINISH, pending input is processed,
+ pending output is flushed and deflate returns with Z_STREAM_END if there was
+ enough output space; if deflate returns with Z_OK, this function must be
+ called again with Z_FINISH and more output space (updated avail_out) but no
+ more input data, until it returns with Z_STREAM_END or an error. After
+ deflate has returned Z_STREAM_END, the only possible operations on the stream
+ are deflateReset or deflateEnd.
+
+ Z_FINISH can be used immediately after deflateInit if all the compression
+ is to be done in a single step. In this case, avail_out must be at least the
+ value returned by deflateBound (see below). Then deflate is guaranteed to
+ return Z_STREAM_END. If not enough output space is provided, deflate will
+ not return Z_STREAM_END, and it must be called again as described above.
+
+ deflate() sets strm->adler to the adler32 checksum of all input read
+ so far (that is, total_in bytes).
+
+ deflate() may update strm->data_type if it can make a good guess about
+ the input data type (Z_BINARY or Z_TEXT). In doubt, the data is considered
+ binary. This field is only for information purposes and does not affect the
+ compression algorithm in any manner.
+
+ deflate() returns Z_OK if some progress has been made (more input
+ processed or more output produced), Z_STREAM_END if all input has been
+ consumed and all output has been produced (only when flush is set to
+ Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
+ if next_in or next_out was Z_NULL), Z_BUF_ERROR if no progress is possible

+
+ Before the call of inflate(), the application should ensure that at least

+ inflate(). If inflate returns Z_OK and with zero avail_out, it must be
+ called again after making room in the output buffer because there might be
+ more output pending.
+
+ The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FINISH,
+ Z_BLOCK, or Z_TREES. Z_SYNC_FLUSH requests that inflate() flush as much
+ output as possible to the output buffer. Z_BLOCK requests that inflate()
+ stop if and when it gets to the next deflate block boundary. When decoding
+ the zlib or gzip format, this will cause inflate() to return immediately
+ after the header and before the first block. When doing a raw inflate,
+ inflate() will go ahead and process the first block, and will return when it
+ gets to the end of that block, or when it runs out of data.
+
+ The Z_BLOCK option assists in appending to or combining deflate streams.
+ Also to assist in this, on return inflate() will set strm->data_type to the
+ number of unused bits in the last byte taken from strm->next_in, plus 64 if
+ inflate() is currently decoding the last block in the deflate stream, plus
+ 128 if inflate() returned immediately after decoding an end-of-block code or
+ decoding the complete header up to just before the first byte of the deflate
+ stream. The end-of-block will not be indicated until all of the uncompressed
+ data from that block has been written to strm->next_out. The number of
+ unused bits may in general be greater than seven, except when bit 7 of
+ data_type is set, in which case the number of unused bits will be less than
+ eight. data_type is set as noted here every time inflate() returns for all
+ flush options, and so can be used to determine the amount of currently
+ consumed input in bits.
+
+ The Z_TREES option behaves as Z_BLOCK does, but it also returns when the
+ end of each deflate block header is reached, before any actual data in that
+ block is decoded. This allows the caller to determine the length of the
+ deflate block header for later use in random access within a deflate block.
+ 256 is added to the value of strm->data_type when inflate() returns
+ immediately after reaching the end of the deflate block header.
+
+ inflate() should normally be called until it returns Z_STREAM_END or an
+ error. However if all decompression is to be performed in a single step (a
+ single call of inflate), the parameter flush should be set to Z_FINISH. In
+ this case all pending input is processed and all pending output is flushed;
+ avail_out must be large enough to hold all of the uncompressed data for the
+ operation to complete. (The size of the uncompressed data may have been
+ saved by the compressor for this purpose.) The use of Z_FINISH is not
+ required to perform an inflation in one step. However it may be used to
+ inform inflate that a faster approach can be used for the single inflate()
+ call. Z_FINISH also informs inflate to not maintain a sliding window if the
+ stream completes, which reduces inflate's memory footprint. If the stream
+ does not complete, either because not all of the stream is provided or not
+ enough output space is provided, then a sliding window will be allocated and
+ inflate() can be called again to continue the operation as if Z_NO_FLUSH had
+ been used.
+
+ In this implementation, inflate() always flushes as much output as
+ possible to the output buffer, and always uses the faster approach on the
+ first call. So the effects of the flush parameter in this implementation are
+ on the return value of inflate() as noted below, when inflate() returns early
+ when Z_BLOCK or Z_TREES is used, and when inflate() avoids the allocation of
+ memory for a sliding window when Z_FINISH is used.
+
+ If a preset dictionary is needed after this call (see inflateSetDictionary
+ below), inflate sets strm->adler to the Adler-32 checksum of the dictionary
+ chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
+ strm->adler to the Adler-32 checksum of all output produced so far (that is,
+ total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
+ below. At the end of the stream, inflate() checks that its computed adler32
+ checksum is equal to that saved by the compressor and returns Z_STREAM_END
+ only if the checksum is correct.
+
+ inflate() can decompress and check either zlib-wrapped or gzip-wrapped
+ deflate data. The header type is detected automatically, if requested when
+ initializing with inflateInit2(). Any information contained in the gzip
+ header is not retained, so applications that need that information should
+ instead use raw inflate, see inflateInit2() below, or inflateBack() and
+ perform their own processing of the gzip header and trailer. When processing
+ gzip-wrapped deflate data, strm->adler32 is set to the CRC-32 of the output
+ producted so far. The CRC-32 is checked against the gzip trailer.
+
+ inflate() returns Z_OK if some progress has been made (more input processed
+ or more output produced), Z_STREAM_END if the end of the compressed data has
+ been reached and all uncompressed output has been produced, Z_NEED_DICT if a

+ inflate() can be called again with more input and more output space to

+
+ This is another version of deflateInit with more compression options. The
+ fields next_in, zalloc, zfree and opaque must be initialized before by the
+ caller.
+
+ The method parameter is the compression method. It must be Z_DEFLATED in
+ this version of the library.
+
+ The windowBits parameter is the base two logarithm of the window size
+ (the size of the history buffer). It should be in the range 8..15 for this
+ version of the library. Larger values of this parameter result in better
+ compression at the expense of memory usage. The default value is 15 if
+ deflateInit is used instead.
+
+ windowBits can also be -8..-15 for raw deflate. In this case, -windowBits
+ determines the window size. deflate() will then generate raw deflate data
+ with no zlib header or trailer, and will not compute an adler32 check value.
+
+ windowBits can also be greater than 15 for optional gzip encoding. Add
+ 16 to windowBits to write a simple gzip header and trailer around the
+ compressed data instead of a zlib wrapper. The gzip header will have no
+ file name, no extra data, no comment, no modification time (set to zero), no
+ header crc, and the operating system will be set to 255 (unknown). If a
+ gzip stream is being written, strm->adler is a crc32 instead of an adler32.
+
+ The memLevel parameter specifies how much memory should be allocated
+ for the internal compression state. memLevel=1 uses minimum memory but is
+ slow and reduces compression ratio; memLevel=9 uses maximum memory for
+ optimal speed. The default value is 8. See zconf.h for total memory usage
+ as a function of windowBits and memLevel.
+
+ The strategy parameter is used to tune the compression algorithm. Use the
+ value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
+ filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no
+ string match), or Z_RLE to limit match distances to one (run-length
+ encoding). Filtered data consists mostly of small values with a somewhat
+ random distribution. In this case, the compression algorithm is tuned to
+ compress them better. The effect of Z_FILTERED is to force more Huffman
+ coding and less string matching; it is somewhat intermediate between
+ Z_DEFAULT_STRATEGY and Z_HUFFMAN_ONLY. Z_RLE is designed to be almost as
+ fast as Z_HUFFMAN_ONLY, but give better compression for PNG image data. The
+ strategy parameter only affects the compression ratio but not the
+ correctness of the compressed output even if it is not set appropriately.
+ Z_FIXED prevents the use of dynamic Huffman codes, allowing for a simpler
+ decoder for special applications.

+ buffer. inflate() can be faster on modern CPUs when used with large
+ buffers. inflateBack() trusts the application to not change the output
+ buffer passed by the output function, at least until inflateBack() returns.
+
+ inflateBackInit() must be called first to allocate the internal state
+ and to initialize the state with the user-provided window buffer.
+ inflateBack() may then be used multiple times to inflate a complete, raw
+ deflate stream with each call. inflateBackEnd() is then called to free the
+ allocated state.
+
+ A raw deflate stream is one with no zlib or gzip header or trailer.
+ This routine would normally be used in a utility that reads zip or gzip
+ files and writes out uncompressed files. The utility would decode the
+ header and process the trailer on its own, hence this routine expects only
+ the raw deflate stream to decompress. This is different from the normal
+ behavior of inflate(), which expects either a zlib or gzip header and
+ trailer around the deflate stream.
+
+ inflateBack() uses two subroutines supplied by the caller that are then
+ called by inflateBack() for input and output. inflateBack() calls those
+ routines until it reads a complete deflate stream and writes out all of the
+ uncompressed data, or until it encounters an error. The function's
+ parameters and return types are defined above in the in_func and out_func
+ typedefs. inflateBack() will call in(in_desc, &buf) which should return the
+ number of bytes of provided input, and a pointer to that input in buf. If
+ there is no input available, in() must return zero--buf is ignored in that
+ case--and inflateBack() will return a buffer error. inflateBack() will call
+ out(out_desc, buf, len) to write the uncompressed data buf[0..len-1]. out()
+ should return zero on success, or non-zero on failure. If out() returns
+ non-zero, inflateBack() will return with an error. Neither in() nor out()
+ are permitted to change the contents of the window provided to
+ inflateBackInit(), which is also the buffer that out() uses to write from.
+ The length written by out() will be at most the window size. Any non-zero
+ amount of input may be provided by in().
+
+ For convenience, inflateBack() can be provided input on the first call by
+ setting strm->next_in and strm->avail_in. If that input is exhausted, then
+ in() will be called. Therefore strm->next_in must be initialized before
+ calling inflateBack(). If strm->next_in is Z_NULL, then in() will be called
+ immediately for input. If strm->next_in is not Z_NULL, then strm->avail_in
+ must also be initialized, and then if strm->avail_in is not zero, input will
+ initially be taken from strm->next_in[0 .. strm->avail_in - 1].
+
+ The in_desc and out_desc parameters of inflateBack() is passed as the
+ first parameter of in() and out() respectively when they are called. These
+ descriptors can be optionally used to pass any information that the caller-
+ supplied in() and out() functions need to do their job.
+
+ On return, inflateBack() will set strm->next_in and strm->avail_in to
+ pass back any unused input that was provided by the last in() call. The
+ return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR
+ if in() or out() returned an error, Z_DATA_ERROR if there was a format error
+ in the deflate stream (in which case strm->msg is set to indicate the nature
+ of the error), or Z_STREAM_ERROR if the stream was not properly initialized.
+ In the case of Z_BUF_ERROR, an input or output error can be distinguished
+ using strm->next_in which will be Z_NULL only if in() returned an error. If
+ strm->next_in is not Z_NULL, then the Z_BUF_ERROR was due to out() returning
+ non-zero. (in() will always be called before out(), so strm->next_in is

+ a strategy: 'f' for filtered data as in "wb6f", 'h' for Huffman-only
+ compression as in "wb1h", 'R' for run-length encoding as in "wb1R", or 'F'
+ for fixed code compression as in "wb9F". (See the description of
+ deflateInit2 for more information about the strategy parameter.) 'T' will
+ request transparent writing or appending with no compression and not using
+ the gzip format.
+
+ "a" can be used instead of "w" to request that the gzip stream that will
+ be written be appended to the file. "+" will result in an error, since
+ reading and writing to the same gzip file is not supported. The addition of
+ "x" when writing will create the file exclusively, which fails if the file
+ already exists. On systems that support it, the addition of "e" when
+ reading or writing will set the flag to close the file on an execve() call.
+
+ These functions, as well as gzip, will read and decode a sequence of gzip
+ streams in a file. The append function of gzopen() can be used to create
+ such a file. (Also see gzflush() for another way to do this.) When
+ appending, gzopen does not test whether the file begins with a gzip stream,
+ nor does it look for the end of the gzip streams to begin appending. gzopen
+ will simply append a gzip stream to the existing file.
+
+ gzopen can be used to read a file which is not in gzip format; in this
+ case gzread will directly read from the file without decompression. When
+ reading, this will be detected automatically by looking for the magic two-
+ byte gzip header.
