1 Tue, 03 Apr 2012 09:59:09 -0700 Google Inc. <opensource (a] google.com> 2 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. 8 9 Tue, 27 Sep 2011 10:30:38 -0700 Google Inc. <opensource (a] google.com> 10 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. 16 17 Fri, 6 Aug 2010 11:36:36 -0800 Google Inc. <opensource (a] google.com> 18 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. 27 28 Tue, 3 Aug 2010 10:44:32 -0800 Google Inc. <opensource (a] google.com> 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. 69 70 Fri, 09 Oct 2009 10:32:10 -0700 Google Inc. <opensource (a] google.com> 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 81 Thu, 09 Apr 2009 09:16:58 -0700 Google Inc. <opensource (a] 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. 112 113 Wed, 18 Mar 2009 14:28:23 -0700 Google Inc. <opensource (a] google.com> 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. 143 144 Thu, 23 Oct 2008 09:03:56 -0700 Google Inc. <opensource (a] google.com> 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. 159 160 Fri, 10 Oct 2008 11:16:23 -0700 Google Inc. <opensource (a] 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. 174 175 Tue, 02 Sep 2008 09:27:54 -0700 Google Inc. <opensource (a] 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::...'" 187 188 Mon, 16 Jun 2008 15:15:51 -0700 Google Inc. <opensource (a] google.com> 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). 193
