librsync/rdiff release 0.9.2
A new release, 0.9.2 of librsync/rdiff is now available for download http://rproxy.sourceforge.net/download.html This version does genuine and (hopefully) reliable delta-compression of files: a viable alternative to diff/patch and xdelta, and a way to do rsync over sneakernet or email. There are still some optimizations to be done, but I hope that at this stage both the programming and the command line interface are in their final form. I'd particularly welcome bug reports about portability, crashes/corruption, or documentation. -- Martin Pool
Re: rsync hard link problems

In some cases, it seems to transfer a hard-linked file again even though the one of the other hard-linked files has already been copied. ... The *end* result is always correct, but in the first case, 1bar gets sent across, but in the second case 3bar is not sent. It seems to have to do with the fact that 1 comes before 2 and 3 comes after 2. I want to use rsync to transfer large trees of files with lots of hard links in them. My plan is to start with one or two directories in the tree, then expand to cover more and eventually all. Obviously if I just started by copying all the files at once, it would be ok, but that's not currently an option. Anyone out there know what's going wrong? Can I do something different to fix it? Is it a bug? I'm afraid that's just the way it is. Rsync can only manage hard links between files that are in the same run, and it just keeps tracks of them in the order in which it encounters them in each run. I'm not sure what else it could do. You probably need to arrange things so that all files that are hardlinked together are always in the same run. Alternatively, after a file is transferred perhaps you create the hardlinks into the next destination directory with your own script before letting rsync loose on it. - Dave Dykstra

I was trying to post a question in the Troubleshooting category and inadvertently created a Subcategory instead(readlink : No such file or directory). I apologize for that. That's no problem; I've just converted it back to a plain question. Thankyou for contributing to it. I would appreciate any input anyone can give as to why I am getting this error. The sending side is detecting the 'readlink : No such file or directory' error and I believe that is why the deletion of any files at the destination is being disabled. I am using version 2.4.6 protocol version 24. The configuration is as follows: local machine: Solaris 7 Remote machine: daemon running on Solaris 8. Has anyone reported rsync functionality problems with Solaris 8? We do test on a Solaris 8 machine donated to the Samba project, but there is no formal regression suite at the moment. Code contributions or design ideas towards that would be welcome. I have tested the same configuration to an AIX box and it is working fine. I receive no errors and the deletion of files works properly. If you or anyone has ideas, any help would be greatly appreciated. PS...I love your idea of using FAQ-O-Matic. Yes, it seems like it might work well. -- Martin Pool, Human Resource Linuxcare. Inc. +61 2 6262 8990 [EMAIL PROTECTED], http://linuxcare.com.au/ Linuxcare. Putting Open Source to work.
Small patch for librsync-0.9.2
This is needed to get it to build on FreeBSD. There are still a number of warnings after this patch which I haven't investigated closely (yet). --- librsync-0.9.2.dist/rsync.h Sun Mar 11 23:25:06 2001 +++ librsync-0.9.2/rsync.h Mon Mar 12 23:48:50 2001 @@ -39,6 +39,8 @@ * See \ref intro for an introduction to use of this library. */ +#include sys/types.h + extern char const rs_librsync_version[]; extern char const rs_licence_string[]; @@ -362,7 +364,7 @@ rs_result rs_loadsig_file(FILE *sig_file, rs_signature_t **sumset); -rs_result rs_file_copy_cb(void *arg, rs_long_t, size_t *len, void **buf); +rs_result rs_file_copy_cb(void *arg, off_t pos, size_t *len, void **buf); rs_result rs_delta_file(rs_signature_t *, FILE *new_file, FILE *delta_file, rs_stats_t *); Thanks, -- Jos Backus _/ _/_/_/"Modularity is not a hack." _/ _/ _/-- D.
