Fold the standalone rsync-web repo into the rsync source tree as rsync-web/, eliminating the sibling-checkout convention and the drift it causes between the release-time HTML snapshot in ../release/rsync-html and the source of truth in ../rsync-web. Flat-copy import (no git history merge). The standalone repo at github.com/RsyncProject/rsync-web is retained for historical reference and will be archived once the in-tree copy proves itself. Add /rsync-web/ to .gitattributes with export-ignore so the website content does not bloat the release source tarball produced by 'git archive' in packaging/release.py step_7_tarball. A follow-up commit repoints HTML_SRC in packaging/release.py at the new in-tree location.

<P>
|
|
The above sections describe the process for constructing a copy of one
|
|
file on a remote system. If we have a several files to copy, we can
|
|
gain a considerable latency advantage by pipelining the process.
|
|
|
|
<P>
|
|
This involves <IMG

initiating two independent processes. One of the
|
|
processes generates and sends the checksums to <IMG

other receives the difference information from <IMG

|
reconstructs the files.
|
|
|
|
<P>
|
|
If the communications link is buffered then these two processes can
|
|
proceed independently and the link should be kept fully utilised in
|
|
both directions for most of the time.
