7 * Bump minor version from 2.2.1 to 2.3.0 to reflect additional rs_sig_args()
8 and strong_len=-1 support.
10 * Add public rs_sig_args() function for getting the recommend signature args
11 from the file size. Added support to rdiff for `--sum-size=-1` to indicate
12 "use minimum size safe against random block collisions". Added warning
13 output for sum-sizes that are too small to be safe. Fixed possible rdiff
14 bug affecting popt parsing on non-little-endian platforms. (dbaarda,
15 https://github.com/librsync/librsync/pull/109)
17 * Fixed yet more compiler warnings for various platforms/compilers.
18 (Adsun701, texierp, https://github.com/librsync/librsync/pull/187,
19 https://github.com/librsync/librsync/pull/188)
21 * Improved cmake popt handling to find popt dependencies using PkgConfig.
22 (ffontaine, https://github.com/librsync/librsync/pull/186)
24 * Tidied internal code and improved tests for netint.[ch], tube.c, and
25 hashtable.h. (dbaarda, https://github.com/librsync/librsync/pull/183
26 https://github.com/librsync/librsync/pull/185).
28 * Improved C99 compatibility. Add `-std=c99 -pedantic` to `CMAKE_C_FLAGS` for
29 gcc and clang. Fix all C99 warnings by making all code C99 compliant. Tidy
30 all CMake checks, #cmakedefines, and #includes. Fix 64bit support for
31 mdfour checksums (texierp, dbaarda,
32 https://github.com/librsync/librsync/pull/181,
33 https://github.com/librsync/librsync/pull/182)
35 * Usage clarified in rdiff (1) man page. (AaronM04,
36 https://github.com/librsync/librsync/pull/180)
42 * Fix #176 hangs calculating deltas for files larger than 4GB. (dbaarda,
43 https://github.com/librsync/librsync/pull/177)
49 * Bump minor version from 2.1.0 to 2.2.0 to reflect additional RabinKarp
52 * Fix MSVC builds by adding missing LIBRSYNC_EXPORT to variables in
53 librsync.h, add -DLIBRSYNC_STATIC_DEFINE to the sumset_test target,
54 and correctly install .dll files in the bin directory.
55 (adsun701, https://github.com/librsync/librsync/pull/161)
57 * Add RabinKarp rollsum support and make it the default. RabinKarp is a much
58 better rolling hash, which reduces the risk of hash collision corruption
59 and speeds up delta calculations. The rdiff cmd gets a new `-R
60 (rollsum|rabinkarp)` argument with the default being `rabinkarp`, Use `-R
61 rollsum` to generate backwards-compatible signatures. (dbaarda,
62 https://github.com/librsync/librsync/issues/3)
64 * Use single-byte literal commands for small inserts in deltas. This makes
65 each small insert use 1 less byte in deltas. (dbaarda,
66 https://github.com/librsync/librsync/issues/120)
68 * Fix multiple warnings (cross-)compiling for windows. (Adsun701,
69 https://github.com/librsync/librsync/pull/165,
70 https://github.com/librsync/librsync/pull/166)
72 * Change rs_file_size() to report -1 instead of 0 for unknown file sizes (not
73 a regular file). (dbaarda https://github.com/librsync/librsync/pull/168)
75 * Add cmake BUILD_SHARED_LIBS option for static library support.
76 BUILD_SHARED_LIBS defaults to ON, and can be set to OFF using `ccmake .` to
77 build librsync as a static library. (dbaarda
78 https://github.com/librsync/librsync/pull/169)
80 * Fix compile errors and add .gitignore entries for MSVS 2019. Fixes
81 hashtable.h to be C99 compliant. (ardovm
82 https://github.com/librsync/librsync/pull/170)
88 * Bump minor version from 2.0.3 to 2.1.0 to reflect additions to librsync.h.
90 * Fix exporting of private symbols from librsync library. Add export of
91 useful large file functions `rs_file_open()`, `rs_file_close()`, and
92 `rs_file_size()` to librsync.h. Add export of `rs_signature_log_stats()` to
93 log signature hashtable hit/miss stats. Improve rdiff error output.
94 (dbaarda, https://github.com/librsync/librsync/issues/130)
96 * Updated release process to include stable tarballs. (dbaarda,
97 https://github.com/librsync/librsync/issues/146)
99 * Remove redundant and broken `--paranoia` argument from rdiff. (dbaarda,
100 https://github.com/librsync/librsync/issues/155)
102 * Fix memory leak of `rs_signature_t->block_sigs` when freeing signatures.
103 (telles-simbiose, https://github.com/librsync/librsync/pull/147)
105 * Document delta file format. (zmj,
106 https://github.com/librsync/librsync/issues/46)
108 * Fix up doxygen comments. (dbaarda,
109 https://github.com/librsync/librsync/pull/151)
115 * Improve CMake install paths configuration (wRAR,
116 https://github.com/librsync/librsync/pull/133) and platform support
117 checking when cross-compiling (fornwall,
118 https://github.com/librsync/librsync/pull/136).
120 * Fix Unaligned memory access for rs_block_sig_init() (dbaarda,
121 https://github.com/librsync/librsync/issues/135).
123 * Fix hashtable_test.c name collision for key_t in sys/types.h on some
124 platforms (dbaarda, https://github.com/librsync/librsync/issues/134)
126 * Format code with consistent style, adding `make tidy` and `make
127 tidyc` targets for reformating code and comments. (dbaarda,
128 https://github.com/librsync/librsync/issues/125)
130 * Removed perl as a build dependency. Note it is still required for some
131 tests. (dbaarda, https://github.com/librsync/librsync/issues/75)
133 * Update RPM spec file for v2.0.2 and fix cmake man page install. (deajan,
134 https://github.com/librsync/librsync/issues/47)
140 * Extensively reworked Doxygen documentation, now available at
141 http://librsync.sourcefrog.net/ (Martin Pool)
143 * Removed some declarations from librsync.h that were unimplemented or no
144 longer ever useful: `rs_work_options`, `rs_accum_value`. Remove
145 declaration of unimplemented `rs_mdfour_file()`. (Martin Pool)
147 * Remove shipped `snprintf` code: no longer acutally linked after changing to
148 CMake, and since it's part of C99 it should be widely available.
151 * Document that Ninja (http://ninja-build.org/) is supported under CMake.
152 It's a bit faster and nicer than Make. (Martin Pool)
154 * `make check` (or `ninja check` etc) will now build and run the tests.
155 Previously due to a CMake limitation, `make test` would only run existing
156 tests and could fail if they weren't built.
157 (Martin Pool, https://github.com/librsync/librsync/issues/49)
159 * Added cmake options to exclude rdiff target and compression from build.
160 See install documentation for details. Thanks to Michele Bertasi.
162 * `popt` is only needed when `rdiff` is being built. (gulikoza)
164 * Improved large file support for platforms using different variants
165 of `fseek` (`fseeko`, `fseeko64`, `_fseeki64`), `fstat` (`fstat64`,
166 `_fstati64`), and `fileno` (`_fileno`). (dbaarda, charlievieth,
167 gulikoza, marius-nicolae)
169 * `rdiff -s` option now shows bytes read/written and speed. (gulikoza).
170 For delta operations it also shows hashtable match statistics. (dbaarda)
172 * Running rdiff should not overwrite existing files (signatures, deltas and
173 new patched files) by default. If the destination file exists, rdiff will
174 now exit with an error. Add new option -f (--force) to overwrite existing
177 * Improve signature memory allocation (doubling size instead of calling
178 realloc for every sig block) and added support for preallocation. See
179 streaming.md job->estimated_signature_count for usage when using the
180 library. `rdiff` uses this by default if possible. (gulikoza, dbaarda)
182 * Significantly tidied signature handling code and testing, resulting in more
183 consistent error handling behaviour, and making it easier to plug in
184 alternative weak and strong sum implementations. Also fixed "slack delta"
185 support for delta calculation with no signature. (dbaarda)
187 * `stdint.h` and `inttypes.h` from C99 is now required. Removed redundant
188 librsync-config.h header file. (dbaarda)
190 * Lots of small fixes for windows platforms and building with MSVC.
191 (lasalvavida, mbrt, dbaarda)
193 * New open addressing hashtable implementation that significantly speeds up
194 delta operations, particularly for large files. Also fixed degenerate
195 behaviour with large number of duplicate blocks like runs of zeros
196 in sparse files. (dbaarda)
198 * Optional support with cmake option for using libb2 blake2 implementation.
199 Also updated included reference blake2 implementation with bug fixes
202 * Improved default values for input and output buffer sizes. The defaults are
203 now --input-size=0 and --output-size=0, which will choose recommended
204 default sizes based on the --block-size and the operation being performed.
207 * Fixed hanging for truncated input files. It will now correctly report an
208 error indicating an unexpected EOF was encountered. (dbaarda,
209 https://github.com/librsync/librsync/issues/32)
211 * Fixed #13 so that faster slack delta's are used for signatures of
212 empty files. (dbaarda,
213 https://github.com/librsync/librsync/issues/13)
215 * Fixed #33 so rs_job_iter() doesn't need calling twice with eof=1.
216 Also tidied and optimized it a bit. (dbaarda,
217 https://github.com/librsync/librsync/issues/33)
219 * Fixed #55 remove excessive rs_fatal() calls, replacing checks for
220 programming errors with assert statements. Now rs_fatal() will only
221 be called for rare unrecoverable fatal errors like malloc failures or
222 impossibly large inputs. (dbaarda,
223 https://github.com/librsync/librsync/issues/55)
229 Note: despite the major version bump, this release has few changes and should
230 be binary and API compatible with the previous version.
232 * Bump librsync version number to 2.0, to match the library
233 soname/dylib version.
234 (Martin Pool, https://github.com/librsync/librsync/issues/48)
236 ## librsync 1.0.1 (2015-11-21)
238 * Better performance on large files. (VictorDenisov)
240 * Add comment on usage of rs_build_hash_table(), and assert correct use.
241 Callers must call rs_build_hash_table() after loading the signature,
242 and before calling rs_delta_begin().
243 Thanks to Paul Harris <paulharris@computer.org>
245 * Switch from autoconf to CMake.
247 Thanks to Adam Schubert.
249 ## librsync 1.0.0 (2015-01-23)
251 * SECURITY: CVE-2014-8242: librsync previously used a truncated MD4
252 "strong" check sum to match blocks. However, MD4 is not cryptographically
253 strong. It's possible that an attacker who can control the contents of one
254 part of a file could use it to control other regions of the file, if it's
255 transferred using librsync/rdiff. For example this might occur in a
256 database, mailbox, or VM image containing some attacker-controlled data.
258 To mitigate this issue, signatures will by default be computed with a
259 256-bit BLAKE2 hash. Old versions of librsync will complain about a
260 bad magic number when given these signature files.
262 Backward compatibility can be obtained using the new
263 `rdiff sig --hash=md4`
264 option or through specifying the "signature magic" in the API, but
265 this should not be used when either the old or new file contain
268 Deltas generated from those signatures will also use BLAKE2 during
269 generation, but produce output that can be read by old versions.
271 See https://github.com/librsync/librsync/issues/5
273 Thanks to Michael Samuel <miknet.net> for reporting this and offering an
276 * Various build fixes, thanks Timothy Gu.
278 * Improved rdiff man page from Debian.
280 * Improved librsync.spec file for building RPMs.
282 * Fixed bug #1110812 'internal error: job made no progress'; on large
285 * Moved hosting to https://github.com/librsync/librsync/
287 * Travis-CI.org integration test at https://travis-ci.org/librsync/librsync/
289 * You can set `$LIBTOOLIZE` before running `autogen.sh`, for example on
290 OS X Homebrew where it is called `glibtoolize`.
292 ## 0.9.7 (released 2004-10-10)
294 * Yet more large file support fixes.
296 * `extern "C"` guards in librsync.h to let it be used from C++.
298 * Removed Debian files from dist tarball.
300 * Changed rdiff to an installed program on "make install".
302 * Refactored delta calculation code to be cleaner and faster.
304 * \#879763: Fixed mdfour to work on little-endian machines which don't
305 like unaligned word access. This should make librsync work on
306 pa-risc, and it makes it slightly faster on ia64.
308 * \#1022764: Fix corrupted encoding of some COPY commands in large
311 * \#1024881: Print long integers directly, rather than via casts to
314 * Fix printf formats for size_t: both the format and the argument
315 should be cast to long.
319 * Large file support fixes.
321 * [v]snprintf or _[v]snprintf autoconf replacement function fix.
323 * Changed installed include file from rsync.h to librsync.h.
325 * Migration to sourceforge for hosting.
327 * Rollsum bugfix that produces much smaller deltas.
329 * Memory leaks bugfix patches.
331 * mdfour bigendian and >512M bugfix, plus optimisations patch.
333 * autoconf/automake updates and cleanups for autoconf 2.53.
335 * Windows compilation patch, heavily modified.
337 * MacOSX compilation patch, modified to autoconf vararg macro fix.
339 * Debian package build scripts patch.
343 * Bugfix patch from Shirish Hemant Phatak
345 ## 0.9.4: (library 1.1.0)
347 * Fixes for rsync.h from Thorsten Schuett <thorsten.schuett@zib.de>
349 * RLL encoding fix from Shirish Hemant Phatak <shirish@nustorage.com>
351 * RPM spec file by Peter J. Braam <braam@clusterfs.com>
353 * No (intentional) changes to binary API.
357 * Big speed improvements in MD4 routines and generation of weak
360 * Patch to build on FreeBSD by Jos Backus <josb@cncdsl.com>
362 * Suggestions to build on Solaris 2.6 from Alberto Accomazzi
363 <aaccomazzi@cfa.harvard.edu>
365 * Add rs_job_drive, a generic mechanism for turning the library into
366 blocking mode. rs_whole_run now builds on top of this. The
367 filebuf interface has changed a little to accomodate it.
369 * Generating and loading signatures now generates statistics.
373 * I suspect there may be a bug in rolling checksums, but it probably
374 only causes inefficiency and not corruption.
376 * Portability fixes for alphaev67-dec-osf5.1; at the moment builds
377 but does not work because librsync tries to do unaligned accesses.
379 * Works on sparc64-unknown-linux-gnu (Debian/2.2)
383 * Improve delta algorithm so that deltas are actually
384 delta-compressed, rather than faked.
388 * Rename the library to `librsync'.
392 * Include the popt library, and use it to build rdiff if the library
393 is not present on the host.
395 * Add file(1) magic for rdiff.
397 * Add more to the manual pages.
399 * It's no longer necessary to call rs_buffers_init on a stream before
400 starting to use it: all the internal data is kept in the job, not
403 * Rename rs_stream_t to rs_buffers_t, a more obvious name. Pass the
404 buffers to every rs_job_iter() call, rather than setting it at
405 startup. Similarly for all the _begin() functions.
407 * rs_job_new also takes the initial state function.
409 * Return RS_PARAM_ERROR when library is misused.
413 * Redesign API to be more like zlib/bzlib.
415 * Put all command-line functions into a single rdiff(1) program.
417 * New magic number `rs6'
419 * Change to using popt for command line parsing.
421 * Use Doxygen for API documentation.
425 * Changes stats string format.
427 * Slightly improved test cases
431 * Don't install debugging tools into /usr/local/bin; leave them in
432 the source directory.
434 * Fix libhsync to build on (sgi-mips, IRIX64, gcc, GNU Make)
436 * Include README.CVS in tarball
438 * Back out of using libtool and shared libraries, as it is
439 unnecessary at this stage, complicates installation and slows down
442 * Use mapptr when reading data to decode, so that decoding should
443 have less latency and be more reliable.
445 * Cope better on systems that are missing functions like snprintf.
449 * Put genuine search encoding back into the nad algorithm, and
450 further clean up the nad code. Literals are now sent out using a
451 literal buffer integrated with the input mapptr so that data is not
452 copied. Checksums are still calculated from scratch each time
453 rather than by rolling -- this is very slow but simple.
455 * Reshuffle test cases so that they use files generated by hsmapread,
456 rather than the source directory. This makes the tests quicker and
457 more reproducible, hopefully without losing coverage. Further
458 develop the test driver framework.
460 * Add hsdumpsums debugging tool.
462 * Hex strings (eg strong checksums) are broken up by underscores for
465 * Stats now go to the log rather than stdout.
467 * mapptr acts properly when we're skipping/rewinding to data already
468 present in the buffer -- it does a copy if required, but not
473 * Improved mapptr input code
475 * Turn on more warnings if using gcc
481 * Improvements to mapptr to make it work better for network IO.
483 * Debug trace code is compiled in unless turned off in ./configure
484 (although most programs will not write it out unless asked.)
486 * Add libhsyncinfo program to show compiled-in settings and version.
488 * Add test cases that run across localhost TCP sockets.
490 * Improved build code; should now build easily from CVS through
493 * Improved trace code.
495 * Clean up to build on sparc-sun-solaris2.8, and in the process clean
496 up the handling of bytes vs chars, and of building without gcc
498 * Reverse build scripts so that driver.sh calls the particular
503 * Use mapptr for input.
505 * Implement a new structure for encoding in nad.c. It doesn't
506 encode at the moment, but it's much more maintainable.
508 * More regression cases.
510 * Clean up build process.
514 * Rewrite hs_inbuf and hs_encode to make them simpler and more
517 * Test cases for input handling.
519 * Use the map_ptr idea for input from both streams and files.
523 * automake/autoconf now works cleanly when the build directory is
524 different to the source directory.
526 * --enable-ccmalloc works again.
530 * A much better regression suite.
532 * CHECKSUM token includes the file's checksum up to the current
533 location, to aid in self-testing.
535 * Various bug fixes, particularly to do with short IO returns.
