Public bug reported:
Affects Version: Jenkins ver. 2.204.2
lsb_release -rd
Description: Ubuntu 18.04.4 LTS
Release: 18.04
Problem:
The jenkins console is not updated on a newline ('\r') character, is is only
updated when a linefeed ('\n') character is written.
Thus output from 'rsync --progress' is not visible until the rsync command
finishes and then the job finishes or is terminated or a linefeed is printed
(e. g. by echo command).
Thus it is not visible on a long running transfer, if the transfer is still
ongoing or if the connection hangs. When aborting/finishing the job or when it
prints a linefeed, everything printed so far including the newlines gets
visible.
This is not caused by the job itself, as the following command
tail -f /var/lib/jenkins/jobs/<JobName>/builds/<BuildNumber>/log
outputs the console log as expected. Thus Jenkins has all information necessary
to display the console as expected.
Expected behaviour:
When a newline occurs, the console of the jenkins job should also be updated in
real time as it is when a linefeed occurs.
** Affects: jenkins (Ubuntu)
