Has xdelta (in ports under misc/xdelta) ever been considered as a means of delivering binary patches for security updates? It seems to be a pretty neat. -- Regards, Michael Nottebrock -------------- next part -------------- A non-text attachment was scrubbed...

Hello, lately I've been playing with the idea of doing in-place updates of systems using either rsync or xdelta. However, both rsync and xdelta seem to be dead set on writing a new file first, and then atomically exchanging it with the old file. Now, as I want to apply a binary delta to a full filesystem, bigger than the available temporary space, this really makes rsync and xdelta

Hi I have a system that I'm trying to run `yum update` on. It fails with the following error: Running rpm_check_debug Running Transaction Test Finished Transaction Test Transaction Check Error: file /usr/share/man/man1/xdelta.1.gz from install of xdelta-1.1.4-1.el5.rf conflicts with file from package xdelta-1.1.3-20 file /usr/share/emacs/site-lisp/psvn.el from install of

Hi list, is there any working solution for deduplication of data for centos? We are trying to find a solution for our backup server which runs a bash script invoking xdelta(3). But having this functionality in fs is much more friendly... We have looked into lessfs, sdfs and ddar. Are these filesystems ready to use (on centos)? ddar is sthg different, I know. Thx Rainer

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,

Hi All, I'm running CentOS 5.3 x86, and recently my yum update isn't running as it should. It pops up with sub conflict messages for i386 packages, which I don't need - even though yum is downloading them. Due to this sub conflict messages, I'm not able to update/install my x86 packages, as the installation stops at the error message. Anybody, any idea how to come over

Hello group, I'm having a very hard time rsyncing efficiently a MySQL database which contains very large binary blobs. (Actually, it's the database of Mantis bug tracker [http://www.mantisbt.org/], with file attachments stored directly in the table rows. I know it's a bad idea from many other reasons, but let's say it was given to me as such.) First, I was dumping the

Hello, I''d like to know if there has been any discussion about adding a new feature to write (add) data at an offset, but without overwriting existing data, or re-writing the existing data. Essentially, in-place addition/removal of data to a file at a place other than the end of the file. Some possible use-cases of such a feature would be: (a) Databases (currently hack around this by

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

For anyone who'd like to check out the latest release of my "rzync" [sic] test release, I've just released a new version. For those that might not have time to look at the code but could provide some feedback based on a rough description, I've created the following simple web page: http://www.clari.net/~wayne/new-protocol.html Here's the tar file of the new

I'm trying to use the rsync algorithm for incremental backups. After a quick look at rsync I saw the batch mode operations, and I thought that maybe I can modify them for incremental backups. What is needed is to add an option to save the checksums of all the files of the level 0 backup and a second option to use the level n checksum to calculate the delta batch files for the level n+1

I came to know about rsync algorithm for transferring files few days ago. The algorithm provides an efficient way to transfer files from one computer to another over a slow communication link. But I have been wondering why don't we see a widespread implementation of rsync in most popular file transfer tools. I know that the algorithm was conceived by Andrew Tridgell and Paul Mackerras from

Hi all, I am writing a xdelta-like application as a personal experiment and am busy implementing the rsync protocol, so far so good. I am using C++ templates and creating the algorithms so that operate on any stream, array, etc. through iterators. All seems well except that I am getting a lot of false hits with the weak checksum. When generating checksums of blocksize 1024 on the RedHat 7.1

Hello, I'm currently evaluating the possibility of implementing a rsync client in a project for my company. The platform used is currently not supported and implementing the client from scratch currently seems to be the most feasible approach. For that I'd be very much interested in a description of the protocol that rsync talks on port 873. Is such a description available somewhere? I

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?

Hey, I'm currently adding rsync to pacman (http://archlinux.org/pacman). A static version of the program is used for rescue operations. Because of this it is impossible to use the rsync client programm via an execve call and we need a version implemented in C. So I started implementing it. But the rsync source isn't beautiful or structured - it's just a big hunk of code. I spent
