- Put sum2_array into sum_struct to hold an array of sum2 checksums
that are each xfer_sum_len bytes.
- Remove sum2 buf from sum_buf.
- Add macro sum2_at() to access each sum2 array element.
- Throw an error if a sums header has an s2length larger than
xfer_sum_len.
- Size flist checksum data to hold the active size, not the max.
- Add a negotiated hash method to the daemon auth code.
- Use EVP for all openssl digests. This makes it easy to add more
openssl digest methods and avoids deprecation warnings.
- Support a way to re-enable deprecated digests via openssl conf
file and allow a default file to be configured.
- Supply a simple openssl-rsync.cnf file to enable legacy digests.
Some systems apparently put strlcpy() into a separate bsd/strings.h file
without putting the function into a separate library. Thus, configure
finds that the function exists for linking but the build does not have
the declaration (which rsync only supplies if it is also supplying its
own version of the function).
- Make the SIMD ASM code off by default. Use configure --enable-simd-asm
to enable.
- Allow MD5 ASM code to be requested even when OpenSSL is handling MD4
checksums. Use configure --enable-md5-asm to enable.
In 2004, an allocation optimization has been added to the file
list handling code, that preallocates 32k of file_struct pointers
in a file_list. This optimization predates the incremental
recursion feature, for which it is not appropriate anymore. When
copying a tree containing a large number of small directories,
using the incremental recursion, rsync allocates many short
file_lists. Suddenly, the unused file_struct pointers can easily
take 90-95% of the memory allocated by rsync.
- use `grep -E` and `grep -F` (`egrep` and `fgrep` are non-standard)
- use same hashbang style for all test scripts
- use explicit comparisons in test scripts
- remove redundant ; from test scripts
- make test script not executable, just like all the other scripts
- unify codestyle across all test scripts
- make openssl license exception clearer by having it at the top
- use modern links in COPYING. The text now matches:
https://www.gnu.org/licenses/gpl-3.0.txt
- fix typo
- Rename unchanged_file() to quick_check_ok().
- Enhance quick_check_ok() to work with non-regular files.
- Add a get_file_type() function to the generator.
- Use the new functions in the generator code to make the logic simpler.
- Fix a bug where the `--alt-dest` functions were not checking if a
special file fully matched the non-permission mode bits before
deciding if we have found an alt-dest match.
- Enhance the `--info=skip --ignore-existing` output to include extra
info on if the existing file differs in type or passes the standard
quick-check logic.
- Add `--info=skip2` that authorizes rsync to perform a slow checksum
"quick check" when ignoring existing files. This provides the uptodate
and differs info even if we need to checksum a file to get it.
- Use C99 flexible arrays when possible, and fall back on the existing
fname[1] kluges on older compilers.
- Avoid static initialization of a flexible array, which is not really
in the C standard.
- All the memory-allocation macros now auto-check for failure and exit
with a failure message that incudes the caller's file and lineno
info. This includes strdup().
- Added the `--max-alloc=SIZE` option to be able to override the memory
allocator's sanity-check limit. It defaults to 1G (as before).
Fixes bugzilla bug 12769.
- Stop setting the mtime on a file we didn't transfer (or didn't verify
the checksum) when the time diff is within the modify window.
- Stop computing a time difference (-1|0|1) when all we care about is
time equality.
