[patch] read-devices
Greetings, I'd like to propose a new option to rsync, which causes it to read device files as if they were regular files. This includes pipes, character devices and block devices (I'm not sure about sockets). The main motivation is cases where you need to synchronize a large amount of data that is not available as regular files, as in the following scenarios: * Keep a copy of a block

Nulls instead of data

readdir() and read() errors ignored
We've just been hit rather badly by a very nasty bug that can cause rsync to silently discard files or fill them with zeroes. It happens when e.g. opendir() succeeds but readdir() returns an error; rsync does not check for an error from readdir() and so simply ignores the error (along with any remaining files in the directory). No error is reported to the user, who will then happily

[PATCH] file_checksum() optimization
When a whole-file checksum is performed, hashing was done in 64 byte blocks, causing overhead and limiting performance. Testing showed the performance improvement to go up quickly going from 64 to 512 bytes, with diminishing returns above, 4096 was where it seemed to plateau for me. Re-used CHUNK_SIZE (32 kB) as it already exists and should be fine to use here anyway. Noticed this because

[PATCH] Btrfs: use cluster->window_start when allocating from a cluster bitmap
We specifically set window_start in the cluster struct to indicate where the cluster starts in a bitmap, but we''ve been using min_start to indicate where we''re searching from. This is usually the start of the blockgroup, so essentially means we''re constantly searching from the start of any bitmap we find, which completely negates all the trouble we go to in order to

Inadequate error checking in rsync 2.5.5
I'm using rsync to mirror files from a Windows XP machine mounted via smbfs. Apparently I have something configured wrong as I get a "permisson denied" error accessing some of the files on the smbfs mount with cp, od, etc. However, rsync produces no error messages on these files. It happily creates files in the target directory that are the right size, but filled with null bytes.

[RFC][patch] dynamic rolling block and sum sizes II
Mark II of the patch set. The first patch (dynsumlen2.patch) increments the protocol version to support per-file dynamic block checksum sizes. It is a prerequisite for varsumlen2.patch. varsumlen2.patch implements per-file dynamic block and checksum sizes. The current block size calculation only applies to files between 7MB and 160MB setting the block size to 1/10,0000 of the file length for a

Problem syncing large dataset
Hi, When using rsync-3.0.2 through 3.0.5, I get this error on a large dataset syncing from machine-a to machine-b: $ /bin/rsync -aHSz /local/. machine-b:/local/. invalid len passed to map_ptr: -1737287498 rsync error: error in file IO (code 11) at fileio.c(188) [sender=3.0.5] This happens no matter which side initiates the connection, so this fails in the same way: $ /bin/rsync -aHSz

map_ptr error
We're using rsync to mirror a web server. The rsync is initiated using ssh from a Red Hat Linux 7.2 box, the files are located on an Alpha running a version of Digital Unix 4. On the Alpha rsync is 2.5.2, The Linux box used to have a 2.4.6-X version, but with the map_ptr problems I built 2.5.2 on that as well. However, version incompatibility was not the problem, as they persist after the
