--timeout option doesn't work when copying between directories
It appears that the --timeout only works when using the rsync protocol, but not when copying between two directories. So if the destination is on a network filesystem and the network link is disconnected, rsync will only abort the operation once the underlying system finally reports that the destination is no longer reachable, which can take quite a while. Is this the intended behavior? If so, should the documentation/manpage spell this out explicitly? -- Please use reply-all for most replies to avoid omitting the mailing list.

It might not be rare, but it's certainly less universally available than awk, which is preinstalled on pretty much every unix-like OS out there. > There are many flavours of AWK.

I tested every common implementation I know of, and found that it didn't work with busybox, awk, I'll be sending the updated patch that works with at least gawk, mawk, nawk, busybox awk, and openbsd awk right after this. -- Please use reply-all for most replies to avoid omitting the mailing list.

rsync CLI protocol documentation
Hi all, I would like to implement rsync compatibility in my app. I'm building an ssh server and I want to support rsync. For example I execute this command: 1) rsync -a -e "ssh -p 2022" /home/nicola/test.sh nicola@127.0.0.1:/ and I get this exec command over ssh: 2) rsync --server -logDtpre.iLsfxC . / I could simply execute the requested command and let it communicate with the remote rsync command at point 1. This should work but I need more control over the uploaded files and their paths. I need to check for user quota ecc.. so basically I need to emulate the protocol implemented in rsync CLI inside my app. There are several libraries that implement rsync protocol itself out of there (for example to create and apply deltas) but I cannot find libraries or documentation about rsync CLI itself. To be more clear, after I receive the rsync command over ssh I get this 4 bytes: 1f 00 00 00 since 1f = 31 this is the protocol version I have to answer with the remote protocol version for example, if I want to emulate protocol version 31: 1f 00 00 00 and then I need to send this 5 (magic) bytes: 3f 94 8b b4 5d after this the rsync client prints: (Client) Protocol versions: remote=31, negotiated=31 FILE_STRUCT_LEN=24, EXTRA_LEN=4 and then sends the file lists. Inside the bytes I receive server side I can read the file name but I need some docs on how to parse these bytes and what I need to expect. I would like to have some documentation about this protocol for rsync CLI, is this documented somewhere? For example I implemented scp support in my app and I found very useful this blog post: https://web.archive.org/web/20170215184048/https://blogs.oracle.com/janp/entry/how_the_scp_protocol_works is there something similar for rsync? Even some suggestions about the relevant source code to study would be helpful, thanks Nicola -- Please use reply-all for most replies to avoid omitting the mailing list.
