I'm using rsync to sync DB files from a FreeBSD box to a Windows XP box under interix. Until today everything was fine but now as soon as the windows box hits one file which is now greater than 2Gb it goes into an infinite loop in generator.c:sum_sizes_sqroot The code at fault seems to be: for (l = len; l >>= 1; b += 2) {} Here's the stack: #0 0x00402ae3 in sum_sizes_sqroot (sum=0x8bf530, len=-2073107852) at generator.c:455 #1 0x00402c56 in generate_and_send_sums (fd=5, len=-2073107852, f_out=4, f_copy=-1) at generator.c:490 #2 0x00405035...

Attached is a patch that makes window strides constant when files are walked with a constant block size. In these cases, it completely avoids all memmoves. In my simple local test of rsyncing 57MB of 10 local files, memmoved bytes went from 18MB to zero. I haven't tested this for a big variety of file cases. I think that this will always reduce the memmoves involved with walking a large

Hello, First of all, thank you for this great software of rsync. If is extremely flexible and powerfull. (my only regret is that i could not find a version for windows dealing properly with charsets in the files' name, might be patched in a future version of cygwin? anyway this is not the subject here [?]). I would like to know how, in the version 3, is computed the default Block-Size? I

Hi, I was trying to synchronize data sitting on our Sun Solaris 8 server with data size of about 800 GB to a remote Linux server in our LAN. Either the rsync process hangs for ever else I get "core dump" after about 15 minutes of time on the source host (solaris 8 server). I used rsync 2.6.2 using the basic command options as shown below # rsync -avz -e rsh <source folder

https://bugzilla.samba.org/show_bug.cgi?id=1529 ------- Additional Comments From thomas@suse.de 2005-09-06 06:37 ------- Now when len is OFF_T is it possible that sum->count (which is size_t) in sum_sizes_sqroot() will rollover too at line: sum->count = (len + (blength - 1)) / blength; ? When we assume all variables have all bits set: 2^64 + (2^32 - 1) / 2^32 = 2^32 + 1 But sum->count can only represent 2^32 and thereofre sum->count will be 0. Did I made a mistake here? -- Con...
