3  Release version 0.8.3 with the following changes:
4  * Issue #34: Move zconf.h, zlib.h, and adler32.c into a zlib subdirectory to
5    avoid conflicts with other revisions of these files included in Chromium.
6    Please see: http://codereview.chromium.org/9555002/
7  * Issue #32: Fix erroneous parameter in unit test.

11  Release version 0.8.2 with the following changes:
12  * Issue #29: Include public header format_extension_flags.h in the Debian
13    package libvcdenc-dev.
14  * Issue #31: Add missing license text to codetablewriter_interface.h and to
15    the packaging scripts.

19  Release version 0.8.1 with the following change:
20  * Issue #24: Revert the fix for Issue #21, which caused a regression
21    (the Debian package did not properly install the vcdiff executable.)
22    This version of open-vcdiff builds and tests successfully using MinGW 5.1.6,
23    so Issue #21 is no longer a problem.
24  * Fix warning in autogen.sh by providing only one directory argument to
25    AC_CONFIG_MACRO_DIR.  The subordinate directory gflags/m4 is still
26    specified as an -I argument to aclocal.

29
30  Release version 0.8 with the following changes:
31  * Issue #12: Truncate decoded_target_ after decoding each window, rather than
32    after each call to DecodeChunk().  This helps limit memory usage when
33    processing multiple windows.
34  * Issue #22: To work around a bug in the gold linker
35    (http://sourceware.org/bugzilla/show_bug.cgi?id=10238), list all direct
36    library dependencies in Makefile.am.
37  * Issue #23: Add an option for the encoder to produce simple JSON output
38    instead of VCDIFF (RFC 3284) format.
39  * Issue #25: Enable VCDIFF_USE_BLOCK_COMPARE_WORDS for the PowerPC
40    architecture as well as for x86.  The test
41    BlockContentsMatchIsAsFastAsBlockCompareWords failed on a PowerPC machine
42    running AIX 5.3.8.
43  * Issue #28: Only call string::reserve() when the required capacity is greater
44    than the string's current capacity.
45  * Get rid of ExitFatal().  It is no longer used for anything since the custom
46    test framework was replaced with gtest.
47  * Get rid of the match count feature.
48  * Rename the log macros: for example, LOG(ERROR) is now VCD_ERROR.
49    Rename COMPILE_ASSERT to VCD_COMPILE_ASSERT.
50  * Simplify RollingHash by performing its sanity checks at compile time.
51  * The googletest package is now referenced as an svn:externals property.
52    Remove the branched googletest sources from src/gtest and instead reference
53    the source files in the top-level gtest directory.
54  * Likewise, the google-gflags package is now referenced as an svn:externals
55    property.  Remove the branched gflags sources from src/gflags and instead
56    reference the source files in the top-level gflags directory.
57  * Use version 1.11 of Automake.
58  * Explicitly include the m4 directory in configuration scripts.
59  * Call LT_INIT from configure.ac as suggested by libtool.
60  * Don't distribute gflags and gtest documents whose names conflict with the
61    same documents in the open-vcdiff package.
62  * Only define _XOPEN_SOURCE if not already defined.
63  * Fix warnings that appeared when compiling on RedHat 9 with gcc 3.2.2:
64      src/encodetable_test.cc:111: warning: cannot pass objects of non-POD
65          type `struct std::string' through `...'; call will abort at runtime
66  * Fix Visual Studio compiler warning about mismatch between size_t and int
67    in blockhash_test.cc.
68  * Add contributors' names to THANKS file.

71
72  Release version 0.7 with the following changes:
73  * Fix a case in which VarintBE::Parse would read off the end of available
74    input if the variable-length integer began with leading zero bytes
75    with their continuation bits set (0x80 bytes.)
76  * Define std::string as string only within namespaces and class definitions
77    in case there is a string class defined at the outermost scope.  If that
78    is the case, the HAS_GLOBAL_STRING label should be defined manually.
79  * Update with changes to gflags package as of 2009/07/23.
80
81Thu, 09 Apr 2009 09:16:58 -0700  Google Inc. <opensource@google.com>
82
83  Release version 0.6 with the following changes:
84  * Issue #9: Add option to optimize VCDIFF decoder when VCD_TARGET will not be
85              used as source segment.
86    Add new interface SetAllowVcdTarget to control whether the VCD_TARGET flag
87    may be used.  If this option is set to false and the decoder finds a
88    VCD_TARGET flag, it will issue an error and refuse to continue decoding.
89  * Issue #19: ERROR: Length of target window (100001916) exceeds limit of
90               67108864 bytes
91    Remove the limit of INT32_MAX on the value of --max_target_file_size, since
92    the new SetAllowVcdTarget feature means that the entire target file will not
93    need to be kept in memory.  Separate vcdecoder_test into five test targets,
94    one of which is devoted to the new SetAllowVcdTarget feature.  Get rid of
95    kMaxBufferSize and kDefaultBufferSize, which were used ambiguously.  A new
96    constant kDefaultMaxTargetSize provides the default values for the
97    --max_target_file_size and --max_target_window_size options.  The
98    --buffersize option, if specified, should control the buffer size used,
99    without limits on its value.
100  * Issue #21: Fail to test on MinGW 5.1.4
101    The wrapper executables produced by libtool failed on MinGW with the error
102    "File /bin/sh not found".  Add the option AC_DISABLE_FAST_INSTALL to avoid
103    creating wrapper executables.  The option implies an extra link step during
104    "make install", but the package is small enough that this does not take
105    long.
106  * Remove the annotated-output feature from the decoder.
107  * Automatically detect and work around a Solaris 10 bug which causes the error
108    "libstdc++.la is not a valid libtool archive".
109        http://whocares.de/2006/05/solaris-10-fixup-for-libstdcla-is-not-a-valid-libtool-archive/
110  * Update with latest changes to gflags package.
111  * Fix type-conversion warning in vcdiff_main.cc in 32-bit Visual Studio build.
112

114
115  * Issue #14: HashedDictionary may free memory twice if implicitly copied.
116    * Add private copy constructor and assignment operator for HashedDictionary.
117  * Issue #18: Building RPM package fails on Fedora 9: Installed (but
118    unpackaged) file vcdiff.1.gz.
119    * Some OS, including Fedora 9, automatically compress man pages that are
120      installed using /usr/bin/install.  This confuses the RPM packager, which
121      expects a file named "vcdiff.1" and finds one named "vcdiff.1.gz" instead.
122      Use a wild-card character to accept either of these two alternatives.
123  * Change the VCDIFF block size to 16, but have the encoder discard all matches
124    smaller than 32 bytes.  This doubles the CPU and memory needed by the
125    encoder, but finds better string matches, producing a more efficient
126    encoding.  Loosen the timing test limit in blockhash_test.cc for the debug
127    build only.
128  * Make the code table writer a virtual interface.
129  * Add an interface SetTargetMatching() to the simple encoder class
130    VCDEncoder.
131  * Remove all references to LOG and logging.h from the unit tests and
132    command-line client.
133  * Remove all special cases for kBlockSize < 4.  kBlockSize must be a multiple
134    of the machine word size (see blockhash.cc), so it will never be smaller
135    than 4.
136  * Use version 1.10 of Automake.
137  * Incorporate recent changes to gflags package
138    (http://code.google.com/p/google-gflags/)
139  * Fix Visual Studio type-mismatch warning in vcdecoder4_test.cc.
140  * Use address cache helper functions IsSameMode(), IsHereMode(), etc. to
141    simplify test code.
142  * Add contributor's name to THANKS file.
143

145
146  * Issue #6: vcdiff crashes with zero-size dictionary
147    * Add special cases for empty dictionary file in vcdiff_main.cc.
148  * Issue #7: vcdiff incorrect binary I/O on Windows
149    * Change stdin/stdout file type to binary in vcdiff_main.cc.
150  * Issue #13: Add unit test for vcdiff command-line executable
151    * Unit test vcdiff_test.bat added for Visual Studio testing of vcdiff.exe.
152      Includes regression tests for issues #6 and #7.
153  * Issue #15: open-vcdiff fails to compile on Fedora 9
154    * Apply patch sent by Daniel Kegel
155    * Add header <string.h> to src/vcdiffengine.cc, which uses memcpy.
156    * Remove const qualifier from integral return types to fix gcc 4.3.1
157      warning.
158  * Add contributors' names to THANKS file.
159
160Fri, 10 Oct 2008 11:16:23 -0700  Google Inc. <opensource@google.com>
161
162  * Issue #15: open-vcdiff fails to compile on Fedora 9
163    * Add header <string.h> to source files that use memcmp, memset, memcpy,
164      and/or strlen.
165    * Change C++-style includes like <cstdlib> to C-style includes like
166      <stdlib.h> so that function names are guaranteed to be defined
167      in the global namespace.
168  * Issue #8: Decoder should not crash if it runs out of memory
169    * Add a new interface that places a limit on the maximum bytes allowed in
170      a single target window or a target file.
171  * Issue #13: Add unit test for vcdiff command-line executable
172    * Unit test vcdiff_test.sh added for Linux and Mac builds.
173    * Still need to add a Windows version of this test.
174
175Tue, 02 Sep 2008 09:27:54 -0700  Google Inc. <opensource@google.com>
176
177  * Fix problems found on OpenBSD platform.
178    * Issue #1: vcdiff command-line executable crashes on startup.
179      This was a problem with the stub intended to replace pthread_once if the
180      package was not linked with the pthreads library.  Simplify gflags.cc to
181      assume single-threaded execution.
182    * Issue #2: Unit test blockhash_test fails.
183      Define VCDIFF_USE_BLOCK_COMPARE_WORDS for BSD platforms to ensure that
184      the most efficient version of memcmp is used in the encoder's inner loop.
185  * Fix compilation warnings in gtest-filepath.cc: "warning: missing
186    initializer for member 'stat::...'"
187

189
190  * open-vcdiff: initial release:
191  The open-vcdiff package provides an encoder and decoder for the VCDIFF format
192  described in RFC 3284 (http://www.ietf.org/rfc/rfc3284.txt).
