Changes in 0.9.7 (released 2004-10-10)
* Yet more large file support fixes.
* C++ support for easy #include <librsync.h> in C++.
* Removed Debian files from dist tarball.
* Changed rdiff to an installed program on "make install".
* Refactored delta calculation code to be cleaner and faster.
* #879763: Fixed mdfour to work on little-endian machines which don't
like unaligned word access. This should make librsync work on
pa-risc, and it makes it slightly faster on ia64.
* #1022764: Fix corrupted encoding of some COPY commands in large
files.
* #1024881: Print long integers directly, rather than via casts to
double.
* Fix printf formats for size_t: both the format and the argument
should be cast to long.
Changes in 0.9.6
* Large file support fixes.
* [v]snprintf or _[v]snprintf autoconf replacement function fix.
* Changed installed include file from rsync.h to librsync.h.
* Migration to sourceforge for hosting.
* Rollsum bugfix that produces much smaller deltas.
* Memory leaks bugfix patches.
* mdfour bigendian and >512M bugfix, plus optimisations patch.
* autoconf/automake updates and cleanups for autoconf 2.53.
* Windows compilation patch, heavily modified.
* MacOSX compilation patch, modified to autoconf vararg macro fix.
* Debian package build scripts patch.
Changes in 0.9.5:
* Bugfix patch from Shirish Hemant Phatak
Changes in 0.9.4: (library 1.1.0)
* Fixes for rsync.h from Thorsten Schuett <thorsten.schuett@zib.de>
* RLL encoding fix from Shirish Hemant Phatak <shirish@nustorage.com>
* RPM spec file by Peter J. Braam <braam@clusterfs.com>
* No (intentional) changes to binary API.
Changes in 0.9.3:
* Big speed improvements in MD4 routines and generation of weak
checksums.
* Patch to build on FreeBSD by Jos Backus <josb@cncdsl.com>
* Suggestions to build on Solaris 2.6 from Alberto Accomazzi
<aaccomazzi@cfa.harvard.edu>
* Add rs_job_drive, a generic mechanism for turning the library into
blocking mode. rs_whole_run now builds on top of this. The
filebuf interface has changed a little to accomodate it.
* Generating and loading signatures now generates statistics.
* More test cases.
* I suspect there may be a bug in rolling checksums, but it probably
only causes inefficiency and not corruption.
* Portability fixes for alphaev67-dec-osf5.1; at the moment builds
but does not work because librsync tries to do unaligned accesses.
* Works on sparc64-unknown-linux-gnu (Debian/2.2)
Changes in 0.9.2:
* Improve delta algorithm so that deltas are actually
delta-compressed, rather than faked.
Changes in 0.9.1:
* Rename the library to `librsync'.
* Portability fixes.
* Include the popt library, and use it to build rdiff if the library
is not present on the host.
* Add file(1) magic for rdiff.
* Add more to the manual pages.
* It's no longer necessary to call rs_buffers_init on a stream before
starting to use it: all the internal data is kept in the job, not
in the stream.
* Rename rs_stream_t to rs_buffers_t, a more obvious name. Pass the
buffers to every rs_job_iter() call, rather than setting it at
startup. Similarly for all the _begin() functions.
* rs_job_new also takes the initial state function.
* Return RS_PARAM_ERROR when library is misused.
Changes in 0.9.0:
* Redesign API to be more like zlib/bzlib.
* Put all command-line functions into a single rdiff(1) program.
* New magic number `rs6'
* Change to using popt for command line parsing.
* Use Doxygen for API documentation.
Changes in 0.5.7:
* Changes stats string format.
* Slightly improved test cases
Changes in 0.5.6:
* Don't install debugging tools into /usr/local/bin; leave them in
the source directory.
* Fix libhsync to build on (sgi-mips, IRIX64, gcc, GNU Make)
* Include README.CVS in tarball
* Back out of using libtool and shared libraries, as it is
unnecessary at this stage, complicates installation and slows down
compilation.
* Use mapptr when reading data to decode, so that decoding should
have less latency and be more reliable.
* Cope better on systems that are missing functions like snprintf.
Changes in 0.5.5:
* Put genuine search encoding back into the nad algorithm, and
further clean up the nad code. Literals are now sent out using a
literal buffer integrated with the input mapptr so that data is not
copied. Checksums are still calculated from scratch each time
rather than by rolling -- this is very slow but simple.
* Reshuffle test cases so that they use files generated by hsmapread,
rather than the source directory. This makes the tests quicker and
more reproducible, hopefully without losing coverage. Further
develop the test driver framework.
* Add hsdumpsums debugging tool.
* Hex strings (eg strong checksums) are broken up by underscores for
readability.
* Stats now go to the log rather than stdout.
* mapptr acts properly when we're skipping/rewinding to data already
present in the buffer -- it does a copy if required, but not
necessarily real IO.
Changes in 0.5.4:
* Improved mapptr input code
* Turn on more warnings if using gcc
* More test cases
Changes in 0.5.3:
* Improvements to mapptr to make it work better for network IO.
* Debug trace code is compiled in unless turned off in ./configure
(although most programs will not write it out unless asked.)
* Add libhsyncinfo program to show compiled-in settings and version.
* Add test cases that run across localhost TCP sockets.
* Improved build code; should now build easily from CVS through
autogen.sh.
* Improved trace code.
* Clean up to build on sparc-sun-solaris2.8, and in the process clean
up the handling of bytes vs chars, and of building without gcc
* Reverse build scripts so that driver.sh calls the particular
script.
Changes in 0.5.2:
* Use mapptr for input.
* Implement a new structure for encoding in nad.c. It doesn't
encode at the moment, but it's much more maintainable.
* More regression cases.
* Clean up build process.
Changes in 0.5.0:
* Rewrite hs_inbuf and hs_encode to make them simpler and more
reliable.
* Test cases for input handling.
* Use the map_ptr idea for input from both streams and files.
Changes in 0.4.1:
* automake/autoconf now works cleanly when the build directory is
different to the source directory.
* --enable-ccmalloc works again.
Changes in 0.4.0:
* A much better regression suite.
* CHECKSUM token includes the file's checksum up to the current
location, to aid in self-testing.
* Various bug fixes, particularly to do with short IO returns.
