Description Olivier Fourdan 2009-07-03 09:31:05 EDT
Created attachment 350434 [details] Proposed patch (backport from upstream) Description of problem: The fix for bug #441691 introduced a regression less, it does not display lines longer that screen width properly, when scrolling line per line. Version-Release number of selected component (if applicable): less-394-6.el5 How reproducible: 100% reproducible Steps to Reproduce: 1. Open a 80x25 terminal 2. less /var/log/messages 3. press "enter" or "cursor down" to scroll line per line Actual results: The lines are truncated, and the same lines are repeated Expected results: The lines display correctly Additional info: The patch "less-394-newline.patch" from bug #441691 that went in less-394-6.el5 seems incomplete. Attached patch backports the missing bits from upstream (for the option --old-bot that was partially introduced in less-394-6.el5).
Comment 5 Olivier Fourdan 2009-07-07 12:43:28 EDT
Sorry, I just find out that the proposed patch is not complete either. When browsing a man page with the arrow cursor down key, the following message appears at times: : ESCOB This did not happen before. So the patch is either incomplete or not totalyl appropriate.

Comment 14 Ben 2010-01-22 07:13:11 EST
Can someone tell me when a fix for this bug will be released, please? Every RHEL5.4 (fully patched) box I have, when scrolling through long files with long lines, garbles the display of a file. Paging through using the space bar works fine. Pressing ctrl-l after the output becomes garbles also works but I was really hoping that line-by-line scrolling would also work. Is there an ETA on this bug being resolved? With thanks.
Comment 15 Olivier Fourdan 2010-01-22 07:33:44 EST
Ben, you may want to try the "--old-bot" option as a workaround as described in this KBase article: http://kbase.redhat.com/faq/docs/DOC-17739
Comment 16 Ben 2010-01-22 07:41:01 EST
Awesome! That fixes my immediate problem. Is there an actual long term solution or am I going to have to change every user's .*profile on every single RHEL5 workstation and server to alias less to "less --old-bot"? Thanks for the pointer.
Comment 17 manuel wolfshant 2010-01-22 07:48:11 EST
Ben, you do know that you could change /etc/bashrc, right ?
Comment 18 Nikola Pajkovsky 2010-01-22 07:54:40 EST
we have a plan to rebase less in RHEL5.
Comment 19 Ben 2010-01-22 08:59:19 EST
manuel: Sorry, I was having a Solaris moment and forgot entirely about /etc/bashrc. Having to do every machine is admittedly slightly less annoying than doing every user on every machine. Nikola: That's great. Thank you. I'll assume 5.5 or 5.6. Either way, enough time from now to make changing /etc/bashrc worthwhile. Apologies all round, generally.

Comment 24 Adam T. Bowen 2010-03-30 06:26:40 EDT
Is there a time delay for this errata to be published? It has been two hours now and I'm still getting a 404. (Sorry about adding this as a comment, but I'm presuming "errata-xmlrpc" isn't a human, so an email to it about this problem would be futile.)
