Hi, Is there a way in which rsync's -z compression (zlib) utility can be benchmarked? I'm trying to compare the compression ratio between rsync and external compression tools like gzip and bzip2. Are there any advantages to using rsync's internal compression mechanism specified with the -z option compared to solely applying external compression i.e. bzip2 to the files and invoking

...the Python interface code. I'm contemplating some cleanup code hacking on librsync and was wondering if the samba based md4sum code was "better" than the RSA code, or if it is worth switching. -- ---------------------------------------------------------------------- ABO: finger abo@minkirri.apana.org.au for more info, including pgp key ----------------------------------------------------------------------

I'm not sure if this is the appropriate forum for questions regarding librsync, but couldn't find any others. I'm trying to get librsync working properly on Solaris 2.7 and 2.8 Sparc servers. The problem is that while librsync appears to compile cleanly, "make check" fails the sources.test. Does anyone have any insight as to why this might be? Might I need a specific

Hi, The following lines in compat.c are rather imprudent: if (read_batch || write_batch) checksum_seed = 32761; else checksum_seed = time(NULL); write_int(f_out,checksum_seed); Setting checksum_seed to a constant in batch mode means block collisions are reproducible and predictable. Thus, some files will be permanently "unlucky" in batch mode and will

Hi, while implementing the rsync protocol in one of our projects I found that the current CVS version still has a MD4 bug. I'm using the FreeBSD libmd implementation and I still had checksum mismatches with protocol version 27 for files whose size was a multiple of 64 - 4 ( - 4 due to checksum_seed). A patch for todays CVS version is attached. Someone should also review the clean_fname()

This patch updates the files under popt/ to the latest vendor drop. The only change is the inclusion of a FreeBSD-specific patch to popt.c. This is needed in case somebody decides to build rsync on that platform without using the port. I'm not happy about the wording in popt/README.rsync so I may change it. The patch is available at http://www.catnook.com/rsync-popt-1.5.1.patch Comments

Hi, Where can I get good pointers on the rolling checksum algorithm used in rsync? I need an 8-bit or 12-bit rolling checksum too. Any place where "rolling" checksum algorithms are discussed?

Is there any chance for rdiff ? I need to frequently synchronize big text file (60MB+) undertaking small changes and I am interested in differences between the subsequent versions [DNS RBL data in dnsbl format, 1E6+ lines of text, new version every 20m, on average 50 new entries (lines) in every synchronization] I would like to get (small) diff file as result of rsync session and apply it to

Hi, I currently create large (500MB-2.5GB) tar.gz files that I am trying to get to rsync better. After doing some research by reading a lecture presented by the original author of rsync and googling the list archives, I have concluded that the gzip-rsyncable.diff is the best way to get gzipped files to rsync nicely. The only version I could find of this patch is available here:

I've been working for the past few months with open-source solutions for syncing Palm PDAs (Coldsync, mostly). I've been becoming increasingly annoyed with Palm's Desktop Link Protocol and the sync mechanism, and am considering replacing it with a third-party application for the Palm. Since I've had good luck with rsync in the past, its seemed an obvious choice. I've

Hello, just being fascinated by rsync I wanted to look at the distribution files at ftp://rsync.samba.org, but it was not possible to get a ftp connection to that address. Is the ftp service down there? Thanks in advance for any soon helpful hint. Have a nice day Michael -- Michael Schmidt mschmidt@fh-koblenz.de MIRROR OF Ghostscript * X-Windows X11

I got used to rsync's -v --progress option so much that I used it instead of rcp even to simply copy files across the network. I dont like software that doesnt talk to me! :-) I like the percentage bar that --progress gives! To my surprise, I found that, when dealing with 1GB+ files, rsync is 4-5 _times_ slower than rcp. Yes, I know that rsync is optimized for sending deltas to a file

Hi, I have a unique issue that I am dealing with here. I need to develop rsync algorithm into a library that can be re-used with my VB / VC application on Windows platform. I need your advice if there is any library already available on the Internet for this? I did get librsync but that is just a header file which I do not know how to compile also with the existing code I have. Can you

On the subject of needed patches, I just recently completed a patch for librsync that fixed the mdfour code to have uint_64 or 2 uint_32's for size. Without this, the checksums on files >512Megs are incorrect. The code should drop into rsync without a hitch. The same goes for mdfour in samba, becuase that is where librsync got the code from anyway. Robert Weber University of

This patch adds the --link-by-hash=DIR option, which hard links received files in a link farm arranged by MD4 file hash. The result is that the system will only store one copy of the unique contents of each file, regardless of the file's name. Anyone have an example of an MD4 collision so I can test that case? :) Patch Summary: -1 +1 Makefile.in -0 +304 hashlink.c (new)

As threatened a while back, there are some exclude/include bugs that I'd like to see fixed in rsync. Here is the patch: http://www.blorf.net/rsync-exclude.patch This fixes the following bugs: - A non-anchored, slash-including pattern with a wildcard needs to be matched at the end of the path (e.g. "CVS/R* should match throughout the tree, not just at /CVS/R*). - A leading
