Description Xingxing Xia 2016-11-16 08:52:53 UTC
Description of problem:
Unneeded spaces when copying content from terminal in web console.
Very inconvenient if user wants to copy the original content.
CLI terminal from oc rsh does not has the issue.

Version-Release number of selected component (if applicable):
openshift v3.4.0.26

How reproducible:

Steps to Reproduce:
1. On web console pod page, in Terminal Tab, execute 'cat /etc/hosts', then copy the output of the `cat` cmd, paste it in 'vi'.

Actual results:
1. In vi, the pasted stuff has unneeded spaces after each line, like:
# Kubernetes-managed hosts file.                                                                                                                                                                    * Here is the end of the unneeded spaces! Same below. *       localhost                                                                                                                                              
::1     localhost ip6-localhost ip6-loopback                                                                                                                           
fe00::0 ip6-localnet                                                                                                                                                   
fe00::0 ip6-mcastprefix                                                                                                                                                
fe00::1 ip6-allnodes                                                                                                                                                   
fe00::2 ip6-allrouters                                                                                                                                             database-1-pcp52

Expected results:
1. Should have no the unneeded spaces, lines.

Created attachment 1221065 [details]

PS: The bugzilla shows 'fe00::0 ip6-localnet', and so on, in 2 lines, because ip6-localnet has too many trailing spaces, thus the browser adjusts it so.

Comment 2 Jessica Forrester 2016-11-16 14:14:21 UTC
I'm fairly certain this is a side effect of how the terminal widget we use works, I'm not sure there is anything we can do to fix this behavior aside from finding a different in-browser terminal to use.

This appears to be fixed with xterm.js.


Comment 5 Xingxing Xia 2017-10-09 08:48:59 UTC
Verified in v3.7.0-0.143.1 with original steps. Issue is fixed, now no unneeded spaces
