After upgrading to rsync 3.2.7, the following command hangs forever
(using "--usermap" causes the hang; without "--usermap" it doesn't
hang):
rsync -v -p -e --usermap user:user /etc/services user@remote:
This command is incorrect: the -e option needs a command.
Without -e this command works for me on Fedora-37 with
rsync-3.2.7-1.fc37.x86_64
I've removed some excessive parameters and filenames from my original
ones, but left over the "-e" which is indeed not needed there.
There seems to be some other requirements for it to be reproduced:
1) transfer on the localhost, Ubuntu 22.10 (rsync
3.2.7-0ubuntu0.22.10.1) - NOT reproducible:
$ rsync -v -p --usermap tch:tch /etc/services tch@localhost:/tmp
services
sent 160 bytes received 149 bytes 618.00 bytes/sec
total size is 12,813 speedup is 41.47
$
2) transfer from Debian 11 (rsync 3.2.3-4+deb11u1) to Ubuntu 22.10
(rsync 3.2.7-0ubuntu0.22.10.1) - reproducible, hangs:
# rsync -p --usermap user:user /etc/services user@10.42.0.47:/tmp
[...never returns, needs ctrl+C...]
Also hangs when the user provided to --usermap does not exist
# rsync -p --usermap does-not-exist:does-not-exist /etc/services
tch@10.42.0.47:/tmp
Unknown --usermap name on receiver: does-not-exist
[...never returns, needs ctrl+C...]
3) transfer from 22.10 (rsync 3.2.7-0ubuntu0.22.10.1) to Ubuntu 22.04
(rsync 3.2.7-0ubuntu0.22.04.2) - NOT reproducible:
$ rsync -p --usermap does-not-exist:does-not-exist /etc/services
tch@192.168.1.23:/tmp
Unknown --usermap name on receiver: does-not-exist
$
4) transfer from Debian 11 (rsync 3.2.3-4+deb11u1) to Ubuntu 22.04
(rsync 3.2.7-0ubuntu0.22.04.2) - reproducible, hangs:
# rsync -p --usermap does-not-exist:does-not-exist /etc/services
tch@192.168.1.23:/tmp
Unknown --usermap name on receiver: does-not-exist
[...never returns, needs ctrl+C...]
So from the tests above, it hangs with rsync 3.2.3 on the sender and
rsync 3.2.7 on the receiver. I'll run some more tests.
