-
- Release version 0.8.4 with the following changes:
- * Issue #35: Add "src/zlib" to the list of additional include directories
- when compiling open-vcdiff with Visual Studio. This addresses a
- regression introduced in version 0.8.3.
- * Issues #36 and #37: Don't use trailing commas in JSON encoding. Add a
- check for non-ASCII characters when using JSON format. Cast char to
- unsigned char when testing whether its value is >= 0x80.
- * Issue #40: Avoid working with negative source offsets if the source data is
- small enough that it does not contain any blocks to hash.
- * Issue #41: Set GTEST_HAS_TR1_TUPLE to 0 so that it excludes
- (unused) std::tuple support when compiling gtest.
- According to the bug, <tr1/tuple> is not available on OS X.
- * Issue #42: Use unique_ptr (if available) instead of auto_ptr.
- * Issue #43: Remove a newline from Makefile.am to fix a reported
- incompatibility with openembedded framework and autoreconf.
- * Fix unused-local-typedefs warnings in GCC 4.7+ by marking the CompileAssert
- typedefs with __attribute__((unused)).
- * Remove unnecessary methods CodeTableWriterInterface::target_length() and
- VCDiffEngine::FinishEncoding().
- * Add the FALLTHROUGH_INTENDED macro to indicate that the lack of a "break;"
- at the end of a case in a switch statement is intentional.
- * Fix the comment for VCDiffFileBasedCoder::OpenFileForReading().
-
-Tue, 03 Apr 2012 09:59:09 -0700 Google Inc. <opensource@google.com>
-
- Release version 0.8.3 with the following changes:
- * Issue #34: Move zconf.h, zlib.h, and adler32.c into a zlib subdirectory to
- avoid conflicts with other revisions of these files included in Chromium.
- Please see: http://codereview.chromium.org/9555002/
- * Issue #32: Fix erroneous parameter in unit test.
-
-Tue, 27 Sep 2011 10:30:38 -0700 Google Inc. <opensource@google.com>
-
- Release version 0.8.2 with the following changes:
- * Issue #29: Include public header format_extension_flags.h in the Debian
- package libvcdenc-dev.
- * Issue #31: Add missing license text to codetablewriter_interface.h and to
- the packaging scripts.
-
-Fri, 6 Aug 2010 11:36:36 -0800 Google Inc. <opensource@google.com>
-
- Release version 0.8.1 with the following change:
- * Issue #24: Revert the fix for Issue #21, which caused a regression
- (the Debian package did not properly install the vcdiff executable.)
- This version of open-vcdiff builds and tests successfully using MinGW 5.1.6,
- so Issue #21 is no longer a problem.
- * Fix warning in autogen.sh by providing only one directory argument to
- AC_CONFIG_MACRO_DIR. The subordinate directory gflags/m4 is still
- specified as an -I argument to aclocal.
-
-Tue, 3 Aug 2010 10:44:32 -0800 Google Inc. <opensource@google.com>
-
- Release version 0.8 with the following changes:
- * Issue #12: Truncate decoded_target_ after decoding each window, rather than
- after each call to DecodeChunk(). This helps limit memory usage when
- processing multiple windows.
- * Issue #22: To work around a bug in the gold linker
- (http://sourceware.org/bugzilla/show_bug.cgi?id=10238), list all direct
- library dependencies in Makefile.am.
- * Issue #23: Add an option for the encoder to produce simple JSON output
- instead of VCDIFF (RFC 3284) format.
- * Issue #25: Enable VCDIFF_USE_BLOCK_COMPARE_WORDS for the PowerPC
- architecture as well as for x86. The test
- BlockContentsMatchIsAsFastAsBlockCompareWords failed on a PowerPC machine
- running AIX 5.3.8.
- * Issue #28: Only call string::reserve() when the required capacity is greater
- than the string's current capacity.
- * Get rid of ExitFatal(). It is no longer used for anything since the custom
- test framework was replaced with gtest.
- * Get rid of the match count feature.
- * Rename the log macros: for example, LOG(ERROR) is now VCD_ERROR.
- Rename COMPILE_ASSERT to VCD_COMPILE_ASSERT.
- * Simplify RollingHash by performing its sanity checks at compile time.
- * The googletest package is now referenced as an svn:externals property.
- Remove the branched googletest sources from src/gtest and instead reference
- the source files in the top-level gtest directory.
- * Likewise, the google-gflags package is now referenced as an svn:externals
- property. Remove the branched gflags sources from src/gflags and instead
- reference the source files in the top-level gflags directory.
- * Use version 1.11 of Automake.
- * Explicitly include the m4 directory in configuration scripts.
- * Call LT_INIT from configure.ac as suggested by libtool.
- * Don't distribute gflags and gtest documents whose names conflict with the
- same documents in the open-vcdiff package.
- * Only define _XOPEN_SOURCE if not already defined.
- * Fix warnings that appeared when compiling on RedHat 9 with gcc 3.2.2:
- src/encodetable_test.cc:111: warning: cannot pass objects of non-POD
- type `struct std::string' through `...'; call will abort at runtime
- * Fix Visual Studio compiler warning about mismatch between size_t and int
- in blockhash_test.cc.
- * Add contributors' names to THANKS file.
-
-Fri, 09 Oct 2009 10:32:10 -0700 Google Inc. <opensource@google.com>
-
- Release version 0.7 with the following changes:
- * Fix a case in which VarintBE::Parse would read off the end of available
- input if the variable-length integer began with leading zero bytes
- with their continuation bits set (0x80 bytes.)
- * Define std::string as string only within namespaces and class definitions
- in case there is a string class defined at the outermost scope. If that
- is the case, the HAS_GLOBAL_STRING label should be defined manually.
- * Update with changes to gflags package as of 2009/07/23.
-
-Thu, 09 Apr 2009 09:16:58 -0700 Google Inc. <opensource@google.com>
-
- Release version 0.6 with the following changes:
- * Issue #9: Add option to optimize VCDIFF decoder when VCD_TARGET will not be
- used as source segment.
- Add new interface SetAllowVcdTarget to control whether the VCD_TARGET flag
- may be used. If this option is set to false and the decoder finds a
- VCD_TARGET flag, it will issue an error and refuse to continue decoding.
- * Issue #19: ERROR: Length of target window (100001916) exceeds limit of
- 67108864 bytes
- Remove the limit of INT32_MAX on the value of --max_target_file_size, since
- the new SetAllowVcdTarget feature means that the entire target file will not
- need to be kept in memory. Separate vcdecoder_test into five test targets,
- one of which is devoted to the new SetAllowVcdTarget feature. Get rid of
- kMaxBufferSize and kDefaultBufferSize, which were used ambiguously. A new
- constant kDefaultMaxTargetSize provides the default values for the
- --max_target_file_size and --max_target_window_size options. The
- --buffersize option, if specified, should control the buffer size used,
- without limits on its value.
- * Issue #21: Fail to test on MinGW 5.1.4
- The wrapper executables produced by libtool failed on MinGW with the error
- "File /bin/sh not found". Add the option AC_DISABLE_FAST_INSTALL to avoid
- creating wrapper executables. The option implies an extra link step during
- "make install", but the package is small enough that this does not take
- long.
- * Remove the annotated-output feature from the decoder.
- * Automatically detect and work around a Solaris 10 bug which causes the error
- "libstdc++.la is not a valid libtool archive".
- http://whocares.de/2006/05/solaris-10-fixup-for-libstdcla-is-not-a-valid-libtool-archive/
- * Update with latest changes to gflags package.
- * Fix type-conversion warning in vcdiff_main.cc in 32-bit Visual Studio build.
-
-Wed, 18 Mar 2009 14:28:23 -0700 Google Inc. <opensource@google.com>
-
- * Issue #14: HashedDictionary may free memory twice if implicitly copied.
- * Add private copy constructor and assignment operator for HashedDictionary.
- * Issue #18: Building RPM package fails on Fedora 9: Installed (but
- unpackaged) file vcdiff.1.gz.
- * Some OS, including Fedora 9, automatically compress man pages that are
- installed using /usr/bin/install. This confuses the RPM packager, which
- expects a file named "vcdiff.1" and finds one named "vcdiff.1.gz" instead.
- Use a wild-card character to accept either of these two alternatives.
- * Change the VCDIFF block size to 16, but have the encoder discard all matches
- smaller than 32 bytes. This doubles the CPU and memory needed by the
- encoder, but finds better string matches, producing a more efficient
- encoding. Loosen the timing test limit in blockhash_test.cc for the debug
- build only.
- * Make the code table writer a virtual interface.
- * Add an interface SetTargetMatching() to the simple encoder class
- VCDEncoder.
- * Remove all references to LOG and logging.h from the unit tests and
- command-line client.
- * Remove all special cases for kBlockSize < 4. kBlockSize must be a multiple
- of the machine word size (see blockhash.cc), so it will never be smaller
- than 4.
- * Use version 1.10 of Automake.
- * Incorporate recent changes to gflags package
- (http://code.google.com/p/google-gflags/)
- * Fix Visual Studio type-mismatch warning in vcdecoder4_test.cc.
- * Use address cache helper functions IsSameMode(), IsHereMode(), etc. to
- simplify test code.
- * Add contributor's name to THANKS file.
-
-Thu, 23 Oct 2008 09:03:56 -0700 Google Inc. <opensource@google.com>
-
- * Issue #6: vcdiff crashes with zero-size dictionary
- * Add special cases for empty dictionary file in vcdiff_main.cc.
- * Issue #7: vcdiff incorrect binary I/O on Windows
- * Change stdin/stdout file type to binary in vcdiff_main.cc.
- * Issue #13: Add unit test for vcdiff command-line executable
- * Unit test vcdiff_test.bat added for Visual Studio testing of vcdiff.exe.
- Includes regression tests for issues #6 and #7.
- * Issue #15: open-vcdiff fails to compile on Fedora 9
- * Apply patch sent by Daniel Kegel
- * Add header <string.h> to src/vcdiffengine.cc, which uses memcpy.
- * Remove const qualifier from integral return types to fix gcc 4.3.1
- warning.
- * Add contributors' names to THANKS file.
-
-Fri, 10 Oct 2008 11:16:23 -0700 Google Inc. <opensource@google.com>
-
- * Issue #15: open-vcdiff fails to compile on Fedora 9
- * Add header <string.h> to source files that use memcmp, memset, memcpy,
- and/or strlen.
- * Change C++-style includes like <cstdlib> to C-style includes like
- <stdlib.h> so that function names are guaranteed to be defined
- in the global namespace.
- * Issue #8: Decoder should not crash if it runs out of memory
- * Add a new interface that places a limit on the maximum bytes allowed in
- a single target window or a target file.
- * Issue #13: Add unit test for vcdiff command-line executable
- * Unit test vcdiff_test.sh added for Linux and Mac builds.
- * Still need to add a Windows version of this test.
-
-Tue, 02 Sep 2008 09:27:54 -0700 Google Inc. <opensource@google.com>
-
- * Fix problems found on OpenBSD platform.
- * Issue #1: vcdiff command-line executable crashes on startup.
- This was a problem with the stub intended to replace pthread_once if the
- package was not linked with the pthreads library. Simplify gflags.cc to
- assume single-threaded execution.
- * Issue #2: Unit test blockhash_test fails.
- Define VCDIFF_USE_BLOCK_COMPARE_WORDS for BSD platforms to ensure that
- the most efficient version of memcmp is used in the encoder's inner loop.
- * Fix compilation warnings in gtest-filepath.cc: "warning: missing
- initializer for member 'stat::...'"
-
-Mon, 16 Jun 2008 15:15:51 -0700 Google Inc. <opensource@google.com>
-
- * open-vcdiff: initial release:
- The open-vcdiff package provides an encoder and decoder for the VCDIFF format
- described in RFC 3284 (http://www.ietf.org/rfc/rfc3284.txt).

-Installation Instructions
-*************************
-
-Copyright (C) 1994-1996, 1999-2002, 2004-2011 Free Software Foundation,
-Inc.
-
- Copying and distribution of this file, with or without modification,

-without warranty of any kind.
-
-Basic Installation
-==================
-
- Briefly, the shell commands `./configure; make; make install' should
-configure, build, and install this package. The following
-more-detailed instructions are generic; see the `README' file for
-instructions specific to this package. Some packages provide this
-`INSTALL' file but do not implement all of the features documented
-below. The lack of an optional feature in a given package is not
-necessarily a bug. More recommendations for GNU packages can be found
-in *note Makefile Conventions: (standards)Makefile Conventions.
-
- The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation. It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions. Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, and a
-file `config.log' containing compiler output (useful mainly for
-debugging `configure').
-
- It can also use an optional file (typically called `config.cache'
-and enabled with `--cache-file=config.cache' or simply `-C') that saves
-the results of its tests to speed up reconfiguring. Caching is
-disabled by default to prevent problems with accidental use of stale
-cache files.
-
- If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release. If you are using the cache, and at
-some point `config.cache' contains results you don't want to keep, you
-may remove or edit it.
-
- The file `configure.ac' (or `configure.in') is used to create
-`configure' by a program called `autoconf'. You need `configure.ac' if
-you want to change it or regenerate `configure' using a newer version
-of `autoconf'.
-
- The simplest way to compile this package is:
-
- 1. `cd' to the directory containing the package's source code and type
- `./configure' to configure the package for your system.
-
- Running `configure' might take a while. While running, it prints
- some messages telling which features it is checking for.
-
- 2. Type `make' to compile the package.
-
- 3. Optionally, type `make check' to run any self-tests that come with
- the package, generally using the just-built uninstalled binaries.
-
- 4. Type `make install' to install the programs and any data files and
- documentation. When installing into a prefix owned by root, it is
- recommended that the package be configured and built as a regular
- user, and only the `make install' phase executed with root
- privileges.
-
- 5. Optionally, type `make installcheck' to repeat any self-tests, but
- this time using the binaries in their final installed location.
- This target does not install anything. Running this target as a
- regular user, particularly if the prior `make install' required
- root privileges, verifies that the installation completed
- correctly.
-
- 6. You can remove the program binaries and object files from the
- source code directory by typing `make clean'. To also remove the
- files that `configure' created (so you can compile the package for
- a different kind of computer), type `make distclean'. There is
- also a `make maintainer-clean' target, but that is intended mainly
- for the package's developers. If you use it, you may have to get
- all sorts of other programs in order to regenerate files that came
- with the distribution.
-
- 7. Often, you can also type `make uninstall' to remove the installed
- files again. In practice, not all packages have tested that
- uninstallation works correctly, even though it is required by the
- GNU Coding Standards.
-
- 8. Some packages, particularly those that use Automake, provide `make
- distcheck', which can by used by developers to test that all other
- targets like `make install' and `make uninstall' work correctly.
- This target is generally not run by end users.
-
-Compilers and Options
-=====================
-
- Some systems require unusual options for compilation or linking that
-the `configure' script does not know about. Run `./configure --help'
-for details on some of the pertinent environment variables.
-
- You can give `configure' initial values for configuration parameters
-by setting variables in the command line or in the environment. Here
-is an example:
-
- ./configure CC=c99 CFLAGS=-g LIBS=-lposix
-
- *Note Defining Variables::, for more details.
-
-Compiling For Multiple Architectures
-====================================
-
- You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory. To do this, you can use GNU `make'. `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script. `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'. This
-is known as a "VPATH" build.
-
- With a non-GNU `make', it is safer to compile the package for one
-architecture at a time in the source code directory. After you have
-installed the package for one architecture, use `make distclean' before
-reconfiguring for another architecture.
-
- On MacOS X 10.5 and later systems, you can create libraries and
-executables that work on multiple system types--known as "fat" or
-"universal" binaries--by specifying multiple `-arch' options to the
-compiler but only a single `-arch' option to the preprocessor. Like
-this:
-
- ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
- CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
- CPP="gcc -E" CXXCPP="g++ -E"
-
- This is not guaranteed to produce working output in all cases, you
-may have to build one architecture at a time and combine the results
-using the `lipo' tool if you have problems.
-
-Installation Names
-==================
-
- By default, `make install' installs the package's commands under
-`/usr/local/bin', include files under `/usr/local/include', etc. You
-can specify an installation prefix other than `/usr/local' by giving
-`configure' the option `--prefix=PREFIX', where PREFIX must be an
-absolute file name.
-
- You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files. If you
-pass the option `--exec-prefix=PREFIX' to `configure', the package uses
-PREFIX as the prefix for installing programs and libraries.
-Documentation and other data files still use the regular prefix.
-
- In addition, if you use an unusual directory layout you can give
-options like `--bindir=DIR' to specify different values for particular
-kinds of files. Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them. In general, the
-default for these options is expressed in terms of `${prefix}', so that
-specifying just `--prefix' will affect all of the other directory
-specifications that were not explicitly provided.
-
- The most portable way to affect installation locations is to pass the
-correct locations to `configure'; however, many packages provide one or
-both of the following shortcuts of passing variable assignments to the
-`make install' command line to change installation locations without
-having to reconfigure or recompile.
-
- The first method involves providing an override variable for each
-affected directory. For example, `make install
-prefix=/alternate/directory' will choose an alternate location for all
-directory configuration variables that were expressed in terms of
-`${prefix}'. Any directories that were specified during `configure',
-but not in terms of `${prefix}', must each be overridden at install
-time for the entire installation to be relocated. The approach of
-makefile variable overrides for each directory variable is required by
-the GNU Coding Standards, and ideally causes no recompilation.
-However, some platforms have known limitations with the semantics of
-shared libraries that end up requiring recompilation when using this
-method, particularly noticeable in packages that use GNU Libtool.
-
- The second method involves providing the `DESTDIR' variable. For
-example, `make install DESTDIR=/alternate/directory' will prepend
-`/alternate/directory' before all installation names. The approach of
-`DESTDIR' overrides is not required by the GNU Coding Standards, and
-does not work on platforms that have drive letters. On the other hand,
-it does better at avoiding recompilation issues, and works well even
-when some directory options were not specified in terms of `${prefix}'
-at `configure' time.
-
-Optional Features
-=================
-
- If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
- Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System). The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
- For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
- Some packages offer the ability to configure how verbose the
-execution of `make' will be. For these packages, running `./configure
---enable-silent-rules' sets the default to minimal output, which can be
-overridden with `make V=1'; while running `./configure
---disable-silent-rules' sets the default to verbose, which can be
-overridden with `make V=0'.
-
-Particular systems
-==================
-
- On HP-UX, the default C compiler is not ANSI C compatible. If GNU
-CC is not installed, it is recommended to use the following options in
-order to use an ANSI C compiler:
-
- ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
-
-and if that doesn't work, install pre-built binaries of GCC for HP-UX.
-
- HP-UX `make' updates targets which have the same time stamps as
-their prerequisites, which makes it generally unusable when shipped
-generated files such as `configure' are involved. Use GNU `make'
-instead.
-
- On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
-parse its `<wchar.h>' header file. The option `-nodtk' can be used as
-a workaround. If GNU CC is not installed, it is therefore recommended
-to try
-
- ./configure CC="cc"
-
-and if that doesn't work, try
-
- ./configure CC="cc -nodtk"
-
- On Solaris, don't put `/usr/ucb' early in your `PATH'. This
-directory contains several dysfunctional programs; working variants of
-these programs are available in `/usr/bin'. So, if you need `/usr/ucb'
-in your `PATH', put it _after_ `/usr/bin'.
-
- On Haiku, software installed for all users goes in `/boot/common',
-not `/usr/local'. It is recommended to use the following options:
-
- ./configure --prefix=/boot/common
-
-Specifying the System Type
-==========================
-
- There may be some features `configure' cannot figure out
-automatically, but needs to determine by the type of machine the package
-will run on. Usually, assuming the package is built to be run on the
-_same_ architectures, `configure' can figure that out, but if it prints
-a message saying it cannot guess the machine type, give it the
-`--build=TYPE' option. TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name which has the form:
-
- CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
- OS
- KERNEL-OS
-
- See the file `config.sub' for the possible values of each field. If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the machine type.
-
- If you are _building_ compiler tools for cross-compiling, you should
-use the option `--target=TYPE' to select the type of system they will
-produce code for.
-
- If you want to _use_ a cross compiler, that generates code for a
-platform different from the build platform, you should specify the
-"host" platform (i.e., that on which the generated programs will
-eventually be run) with `--host=TYPE'.
-
-Sharing Defaults
-================
-
- If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists. Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Defining Variables
-==================
-
- Variables not defined in a site shell script can be set in the
-environment passed to `configure'. However, some packages may run
-configure again during the build, and the customized values of these
-variables may be lost. In order to avoid this problem, you should set
-them in the `configure' command line, using `VAR=value'. For example:
-
- ./configure CC=/usr/local2/bin/gcc
-
-causes the specified `gcc' to be used as the C compiler (unless it is
-overridden in the site shell script).
-
-Unfortunately, this technique does not work for `CONFIG_SHELL' due to
-an Autoconf bug. Until the bug is fixed you can use this workaround:
-
- CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
-
-`configure' Invocation
-======================
-
- `configure' recognizes the following options to control how it
-operates.
-
-`--help'
-`-h'
- Print a summary of all of the options to `configure', and exit.
-
-`--help=short'
-`--help=recursive'
- Print a summary of the options unique to this package's
- `configure', and exit. The `short' variant lists options used
- only in the top level, while the `recursive' variant lists options
- also present in any nested packages.
-
-`--version'
-`-V'
- Print the version of Autoconf used to generate the `configure'
- script, and exit.
-
-`--cache-file=FILE'
- Enable the cache: use and save the results of the tests in FILE,
- traditionally `config.cache'. FILE defaults to `/dev/null' to
- disable caching.
-
-`--config-cache'
-`-C'
- Alias for `--cache-file=config.cache'.
-
-`--quiet'
-`--silent'
-`-q'
- Do not print messages saying which checks are being made. To
- suppress all normal output, redirect it to `/dev/null' (any error
- messages will still be shown).
-
-`--srcdir=DIR'
- Look for the package's source code in directory DIR. Usually
- `configure' can determine that directory automatically.
-
-`--prefix=DIR'
- Use DIR as the installation prefix. *note Installation Names::
- for more details, including other options available for fine-tuning
- the installation locations.
-
-`--no-create'
-`-n'
- Run the configure checks, but stop before creating any output
- files.
-
-`configure' also accepts some other, not widely useful, options. Run
-`configure --help' for more details.

-open-vcdiff is an encoder and decoder for the VCDIFF format, as described in
-RFC 3284 : The VCDIFF Generic Differencing and Compression Data Format
-(http://www.ietf.org/rfc/rfc3284.txt)
-A library with a simple API is included, as well as a command-line executable
-that can apply the encoder and decoder to source, target, and delta files.
-For further details, please refer to:
-http://code.google.com/p/open-vcdiff/wiki/HowToUseOpenVcdiff
-
-See INSTALL for (generic) installation instructions for C++: basically
- ./configure && make && make install
-
-This should compile the unit tests as well as "vcdiff", a simple command-line
-utility to run the encoder and decoder. Typical usage of vcdiff is as follows
-(the "<" and ">" are file redirect operations, not optional arguments):
- vcdiff encode -dictionary file.dict < target_file > delta_file
- vcdiff decode -dictionary file.dict < delta_file > target_file
-To see the command-line syntax of vcdiff, use "vcdiff --help" or just "vcdiff".
-
-To call the encoder from C++ code, assuming that dictionary, target, and delta
-are all std::string objects:
-#include <google/vcencoder.h> // Read this file for interface details
-[...]
- open_vcdiff::VCDiffEncoder encoder(dictionary.data(), dictionary.size());
- encoder.SetFormatFlags(open_vcdiff::VCD_FORMAT_INTERLEAVED);
- encoder.Encode(target.data(), target.size(), &delta);
-
-Calling the decoder is just as simple:
-#include <google/vcdecoder.h> // Read this file for interface details
-[...]
- open_vcdiff::VCDiffDecoder decoder;
- decoder.Decode(dictionary.data(), dictionary.size(), delta, &target);
-
-When using the encoder, the C++ application must be linked with the library
-options -lvcdcom and -lvcdenc; when using the decoder, it must be linked with
--lvcdcom and -lvcddec.
-
-To verify that the package works on your system, especially after making
-modifications to the source code, please run the unit tests using
- make check
-
-For further details, please refer to:
-http://code.google.com/p/open-vcdiff/wiki/HowToUseOpenVcdiff

-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
-# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory. The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run. This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-# fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-# fails if $ac_aux_dir is absolute,
-# fails when called from a subdirectory in a VPATH build with
-# a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir. In an in-source build this is usually
-# harmless because $srcdir is `.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
-# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-# MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH. The drawback is that using absolute paths prevent a
-# configured tree to be moved without reconfiguration.

-\`configure' configures open-vcdiff 0.8.4 to adapt to many kinds of systems.
-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE. See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
- -h, --help display this help and exit
- --help=short display options specific to this package
- --help=recursive display the short help of all the included packages
- -V, --version display version information and exit
- -q, --quiet, --silent do not print \`checking ...' messages
- --cache-file=FILE cache test results in FILE [disabled]
- -C, --config-cache alias for \`--cache-file=config.cache'
- -n, --no-create do not create output files
- --srcdir=DIR find the sources in DIR [configure dir or \`..']
-
-Installation directories:
- --prefix=PREFIX install architecture-independent files in PREFIX
- [$ac_default_prefix]
- --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
- [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:
- --bindir=DIR user executables [EPREFIX/bin]
- --sbindir=DIR system admin executables [EPREFIX/sbin]
- --libexecdir=DIR program executables [EPREFIX/libexec]
- --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
- --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
- --localstatedir=DIR modifiable single-machine data [PREFIX/var]
- --libdir=DIR object code libraries [EPREFIX/lib]
- --includedir=DIR C header files [PREFIX/include]
- --oldincludedir=DIR C header files for non-gcc [/usr/include]
- --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
- --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
- --infodir=DIR info documentation [DATAROOTDIR/info]
- --localedir=DIR locale-dependent data [DATAROOTDIR/locale]
- --mandir=DIR man documentation [DATAROOTDIR/man]
- --docdir=DIR documentation root [DATAROOTDIR/doc/open-vcdiff]
- --htmldir=DIR html documentation [DOCDIR]

-Optional Features:
- --disable-option-checking ignore unrecognized --enable/--with options
- --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
- --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
- --disable-dependency-tracking speeds up one-time build
- --enable-dependency-tracking do not reject slow dependency extractors
- --enable-shared[=PKGS] build shared libraries [default=yes]
- --enable-static[=PKGS] build static libraries [default=yes]
- --enable-fast-install[=PKGS]
- optimize for fast installation [default=yes]
- --disable-libtool-lock avoid locking (might break parallel builds)
- --enable-namespace=FOO to define these Google
- classes in the FOO namespace. --disable-namespace
- to define them in the global namespace. Default
- is to define them in namespace google.
-
-Optional Packages:
- --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
- --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
- --with-pic[=PKGS] try to use only PIC/non-PIC objects [default=use
- both]
- --with-gnu-ld assume the C compiler uses GNU ld [default=no]
- --with-sysroot=DIR Search for dependent libraries within DIR
- (or the compiler's sysroot if not specified).
-
-Some influential environment variables:
- CC C compiler command
- CFLAGS C compiler flags
- LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
- nonstandard directory <lib dir>
- LIBS libraries to pass to the linker, e.g. -l<library>
- CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
- you have headers in a nonstandard directory <include dir>
- CPP C preprocessor
- CXX C++ compiler command
- CXXFLAGS C++ compiler flags
- CXXCPP C++ preprocessor
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.
-

-# Usage: $progname [OPTION]... [MODE-ARG]...
-#
-# Provide generalized library-building support services.
-#
-# --config show all configuration variables
-# --debug enable verbose shell tracing
-# -n, --dry-run display commands without modifying any files
-# --features display basic configuration information and exit
-# --mode=MODE use operation mode MODE
-# --preserve-dup-deps don't remove duplicate dependency libraries
-# --quiet, --silent don't print informational messages
-# --no-quiet, --no-silent
-# print informational messages (default)
-# --no-warn don't display warning messages
-# --tag=TAG use configuration variables from tag TAG
-# -v, --verbose print more informational messages than default
-# --no-verbose don't print the extra informational messages
-# --version print version information
-# -h, --help, --help-all print short, long, or detailed help message
-#
-# MODE must be one of the following:
-#
-# clean remove files from the build directory
-# compile compile a source file into a libtool object
-# execute automatically set library path, then run a program
-# finish complete the installation of libtool libraries
-# install install libraries or executables
-# link create a library or an executable
-# uninstall remove libraries from an installed directory
-#
-# MODE-ARGS vary depending on the MODE. When passed as first option,

-# These exist entirely to fool aclocal when bootstrapping libtool.
-#
-# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
-# which have later been changed to m4_define as they aren't part of the
-# exported API, or moved to Autoconf or Automake where they belong.
-#
-# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
-# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
-# using a macro with the same name in our local m4/libtool.m4 it'll
-# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
-# and doesn't know about Autoconf macros at all.)
-#
-# So we provide this file, which has a silly filename so it's always
-# included after everything else. This provides aclocal with the
-# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
-# because those macros already exist, or will be overwritten later.
-# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
-#
-# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
-# Yes, that means every name once taken will need to remain here until
-# we give up compatibility with versions before 1.7, at which point
-# we need to keep only those names which we still refer to.

-reconstruct target file from dictionary and delta file
-.HP
-\fB\-dictionary\fR <filename>
-.br
-File containing dictionary data (also known as source data.)
-Required for all operations.
-.HP
-\fB\-target\fR <filename>
-.br
-File name of the target file (unencoded data).
-The default value (blank) causes vcdiff to use standard input for encode,
-or standard output for decode.
-.HP
-\fB\-delta\fR <filename>
-.br
-File name of the delta file (encoded data).
-The default value (blank) causes vcdiff to use standard output for encode,
-or standard input for decode.
-.HP
-\fB\-checksum\fR
-.br
-Include an Adler32 checksum of the target data when encoding.
-Default is false.
-.HP
-\fB\-interleaved\fR
-.br
-Use interleaved format. Default is false.
-.HP
-\fB\-stats\fR
-.br
-Write a report to stderr, containing the original target size,
-compressed delta size, and compression percentage.
-Default is false.
-.HP
-\fB\-target_matches\fR
-.br
-Find duplicate strings in target data as well as dictionary data.
-Default is false.
-.HP
-\fB\-buffersize\fR <integer>
-.br
-The memory buffer size (in bytes) used for reading the input file.
-Default is 1048576 (1 MB); if the input file is smaller than that,
-the buffer will match the file size. This parameter does not usually
-need to be specified.

-// * The VCDAddress type is large enough to hold any offset within

-// The source (dictionary) should not approach this size limit;
-// to compress a target file that is larger than

-// break it up into multiple target windows.

-// all addresses between 0 and (here_address - 1) are valid, and
-// any other address is invalid.
-// mode: A byte value between 0 and (near_cache_size_ + same_cache_size_ + 1)
-// which tells how to interpret the next value in the address stream.
-// The values 0 and 1 correspond to SELF and HERE addressing.
-// The validity of "mode" should already have been checked before
-// calling this function.
-// address_stream: Points to a pointer holding the position
-// in the "Addresses section for COPYs" part of the input data.
-// That section must already have been uncompressed
-// using a secondary decompressor (if necessary.)
-// This is an IN/OUT argument; the value of *address_stream will be
-// incremented by the size of an integer, or (if the SAME cache
-// was used) by the size of a byte (1).
-// address_stream_end: Points to the position just after the end of
-// the address stream buffer. All addresses between *address_stream
-// and address_stream_end should contain valid address data.

-// Return value: If the input conditions were met, and the address section
-// of the input data contains properly encoded addresses that match
-// the instructions section, then an integer between 0 and here_address - 1
-// will be returned, representing the address from which data should

-// is expected, this means that the consumer should block and wait
-// for more data before continuing to decode. If no more data is expected,

- // is equal to the dictionary size. FindBestMatch() will add

- // in order to produce the correct offset value for a target BlockHash.
- // 2. For a dictionary BlockHash, the entire data set is hashed at once
- // when Init() is called with the parameter populate_hash_table = true.
- // For a target BlockHash, because the previously encoded target data
- // includes only the data seen up to the current encoding position,
- // the data blocks are hashed incrementally as the encoding position
- // advances, using AddOneIndexHash() and AddAllBlocksThroughIndex().
- //
- // The following two factory functions can be used to create BlockHash
- // objects for each of these two purposes. Each factory function calls
- // the object constructor and also calls Init(). If an error occurs,
- // NULL is returned; otherwise a valid BlockHash object is returned.
- // Since a dictionary BlockHash is not expected to be modified after

- // If no such match is found, this function leaves *best_match unmodified.
- //
- // On calling FindBestMatch(), best_match must

- // The same Match object can be passed
- // when calling FindBestMatch() on a different BlockHash object
- // for the same candidate data block, in order to find
- // the best match possible across both objects. For example:
- //
- // open_vcdiff::BlockHash::Match best_match;
- // uint32_t hash_value =
- // RollingHash<BlockHash::kBlockSize>::Hash(target_candidate_start);
- // bh1.FindBestMatch(hash_value,

- // target_candidate_start,
- // target_start,
- // target_length,
- // &best_match);
- // if (best_size >= 0) {
- // // a match was found; its size, source offset, and target offset
- // // can be found in best_match
- // }
- //
- // hash_value is passed as a separate parameter from target_candidate_start,
- // (rather than calculated within FindBestMatch) in order to take
- // advantage of the rolling hash, which quickly calculates the hash value
- // of the block starting at target_candidate_start based on
- // the known hash value of the block starting at (target_candidate_start - 1).
- // See vcdiffengine.cc for more details.
- //
- // Example:
- // kBlockSize: 4
- // target text: "ANDREW LLOYD WEBBER"
- // 1^ 5^2^ 3^
- // dictionary: "INSURANCE : LLOYDS OF LONDON"

-// The VCDiff format allows each opcode to represent either

-// examine the opcode generated by the last call to EncodeInstruction.
-// If that opcode was a single-instruction opcode, this function checks
-// whether there is a compound (double-instruction) opcode that can
-// combine that single instruction with the instruction that is now
-// being added, and so save a byte of space. In that case, the
-// single-instruction opcode at position last_opcode_index_ will be
-// overwritten with the new double-instruction opcode.
-//
-// In the majority of cases, no compound opcode will be possible,
-// and a new single-instruction opcode will be appended to
-// instructions_and_sizes_, followed by a representation of its size
-// if the opcode does not implicitly give the instruction size.
-//
-// As an example, say instructions_and_sizes_ contains 10 bytes, the last
-// of which contains the opcode 0x02 (ADD size 1). Because that was the
-// most recently added opcode, last_opcode_index_ has the value 10.

-// The function will replace the old opcode 0x02 with the double-instruction
-// opcode 0xA3 (ADD size 1 + COPY size 4 mode 0).
-//
-// All of the double-instruction opcodes in the standard code table
-// have implicit sizes, meaning that the size of the instruction will not
-// need to be written to the instructions_and_sizes_ string separately
-// from the opcode. If a custom code table were used that did not have
-// this property, then instructions_and_sizes_ might contain a
-// double-instruction opcode (say, COPY size 0 mode 0 + ADD size 0)
-// followed by the size of the COPY, then by the size of the ADD.
-// If using the SDCH interleaved format, the address of the COPY instruction

- 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 (for example if an input file is mmap'ed), 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.

-
- On 16-bit systems, the functions zalloc and zfree must be able to allocate
- exactly 65536 bytes, but will not be required to allocate more than this
- if the symbol MAXSEG_64K is defined (see zconf.h). WARNING: On MSDOS,

- requirements and avoid any allocation of 64K objects, at the expense of
- compression ratio, compile the library with -DMAX_WBITS=14 (see zconf.h).

- The fields total_in and total_out can be used for statistics or

- 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 accumualte 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.
-
- 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). If deflate does not return
- Z_STREAM_END, then 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 NULL), Z_BUF_ERROR if no progress is possible
- (for example avail_in or avail_out was zero). Note that Z_BUF_ERROR is not
- fatal, and deflate() can be called again with more input and more output

- inflate decompresses 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. inflate performs one or both of the
- following actions:
-
- - Decompress 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 is updated and processing
- will resume at this point for the next call of inflate().
-
- - Provide more output starting at next_out and update next_out and avail_out
- accordingly. inflate() provides as much output as possible, until there
- is no more input data or no more space in the output buffer (see below
- about the flush parameter).
-
- Before the call of inflate(), the application should ensure that at least
- one of the actions is possible, by providing more input and/or consuming
- more output, and updating the next_* and avail_* values accordingly.
- The application can consume the uncompressed output when it wants, for
- example when the output buffer is full (avail_out == 0), or after each
- call of 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, or Z_BLOCK. 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.
-
- 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 the
- uncompressed data. (The size of the uncompressed data may have been saved
- by the compressor for this purpose.) The next operation on this stream must
- be inflateEnd to deallocate the decompression state. The use of Z_FINISH
- is never required, but can be used to inform inflate that a faster approach
- may be used for the single inflate() call.
-
- 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 only effect of the flush parameter in this implementation
- is on the return value of inflate(), as noted below, or when it returns early
- because Z_BLOCK is used.
-
- If a preset dictionary is needed after this call (see inflateSetDictionary
- below), inflate sets strm->adler to the adler32 checksum of the dictionary
- chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
- strm->adler to the adler32 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() will decompress and check either zlib-wrapped or gzip-wrapped
- deflate data. The header type is detected automatically. 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.
-
- 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
- preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
- corrupted (input stream not conforming to the zlib format or incorrect check
- value), Z_STREAM_ERROR if the stream structure was inconsistent (for example
- if next_in or next_out was NULL), Z_MEM_ERROR if there was not enough memory,
- Z_BUF_ERROR if no progress is possible or if there was not enough room in the
- output buffer when Z_FINISH is used. Note that Z_BUF_ERROR is not fatal, and
- inflate() can be called again with more input and more output space to
- continue decompressing. If Z_DATA_ERROR is returned, the application may then
- call inflateSync() to look for a good compression block if a partial recovery
- of the data is desired.

- 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 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.

- inflateBackInit() must be called first to allocate the internal state

-
- A raw deflate stream is one with no zlib or gzip header or trailer.

- 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

- 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

- 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 is not Z_NULL, then the Z_BUF_ERROR was due to
- out() returning non-zero. (in() will always be called before out(), so
