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

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()

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

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, 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:

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

G'day, I've been working on a Python interface to librsync and have noticed that it uses md4sum code borrowed from Andrew Tridgell and Martin Pool that comes via rsync and was originally written for samba. Is there anything special about this code compared to the RSA md4sum code that can be found with libmd <"http://www.penguin.cz/~mhi/libmd/">? Python uses the RSA

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?

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

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

I'm interested in these very questions (librsync-rsync relationship, remaining limitations of rsync, active prospects for ground-up rewrites), Google searches for rsync info have proved a little too vague due to the programs ubiquity. Much has certainly changed since this was written, could some people with knowledge in these areas could update martin's response for the state of rsync,

hello, I'm new to this list. here is my question: I would like to synchronize two computers (say the home one and the job one) using zip drives or similar (cdroms, etc), since modem lines are quite slow and expensive (in Italy). I though I could produce the "signature" of files on home computer, store it on a zip, go to job, run rsync to copy the missing or altered files on

I have the text_field_with_auto_complete woking on my user DB using last_name. so looking for ''ivanoff'' works great, but I can''t find ''john''. Plus I like to have ''last_name, first_name'' show up in the dropdown. what I can''t figure out is how to concat first_name and last_name to make a name and use that to look it. working

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)

Dear guru's Hopefully someone can shed some light in my issue. I have created a queue with a ringall strategy and all works fine. I want a caller to be able to exit the queue so they can leave a message. I've added the H option in queue command so callers can press * to exit. So far all well, on the cli there is a message the caller pressed * and the extensions stops ringing. But

This is a stupid question... Why would one use a streaming audio server versus just a web server to stream static files like a juke box? Here are some reasons I came up with: 1) A web server won't concatinate songs together, but if someone is only downloading say a one-off clip, perhaps a web server is exactly what is needed 2) Titles (or rather meta-data) don't get inserted into the
