Hi Lapo,
I was building up a synchronization mechanism for
a distributed metadata environment and the scripts
ran fine on Linux but tangled on Cygwin/rsync.
Behavior is that the cygwin rsync blocks after
some number of consecutive/sequential but rapid rsync
commands, ?? 20 ??
When I substitute scp (with appropriate change
of parameters for scp) the scripts work fine
on cygwin.
Parameters using:
rsync -e ssh --blocking-io --compress --ignore-times
scp -qBC
I have no idea if the problem is rooted in:
Win2K
cygwin (current)
rsync port on cygwin
Feel free to email me if you want the actual
message. I'm under a lot of pressure to get
this out the door so don't have time to dig
into much more than passing this flag on to
you.
BTW, please do not treat this as a complaint,
I'm very grateful that Cygwin exists and is
available for us to use. I'm just trying to
help out by relaying information upstream.
I know of the problem, but unfortunately in this period I have too few
time to debug it extensively.
Someone else seems to have done it though:
http://sources.redhat.com/ml/cygwin/2002-09/msg01155.html
http://sources.redhat.com/ml/cygwin/2002-10/msg00296.html
In the first message there is an analysis that seems to indicate that is
"cygwin's fault" but that there can be a patch do rsync itswelf to avoid
the problem.
The second message contains a precompiled EXE with the patch included.
I had yet no time to study relevant cygwinsources to find a real "solution".
BTW: please use the ML for questions so that everyone can read it
