Red Hat Bugzilla – Bug 127239
ncurses isn't polling current TERMINFO db
Last modified: 2007-11-30 17:10:45 EST
Description of problem: Building htop-0.3.3-1, upon run, display is completely degraded (can only see some of the processes, can't see any of the proc info by scrolling right). Version-Release number of selected component (if applicable): ncurses-5.4-5 How reproducible: Every time, regardless of console type. Steps to Reproduce: 1. Download and build htop (htop.sourceforge.net). 2. Run app in terminal (window manager doesn't make a difference). 3. Actual results: Displays only about half of what it did on FC1. Expected results: Full display and refresh. Additional info: After troubleshooting with project creator, found that setting TERM=xterm-color corrects display. Rebuilding ncurses from source also fixes problem. I've installed from several different repositories, with the same degraded results. ncurses-5.4-5 rpm needs to be rebuilt and redistributed I'm guessing.
What does infocmp show? And what terminal emulator? (Presumably gnome-terminal, but not stated). htop 3.3 works fine on my Debian/testing in uxterm.
The problem is not with ncurses per se, rather with Fedora Core 2's main rpm repositories. Tested on gnome-terminal, konsole, xterm & uxterm, at which point it seemed ubiquitous and I didn't worry about rxvt or eterm. A simple rebuild of ncurses src rpm did the trick. First few lines of infocmp on FC2 gnome-terminal: ------------------ # Reconstructed via infocmp from file: /usr/share/terminfo/x/xterm xterm|xterm terminal emulator (X Window System), am, bce, km, mir, msgr, xenl, colors#8, cols#80, it#8, lines#24, pairs#64, acsc=``aaffggiijjkkllmmnnooppqqrrssttuuvvwwxxyyzz{{||}}~~, ------------------ I have been running htop on Debian (Sarge & Woody), Libranet 2.8.1, Knoppix, DSL 0.3.7, ArchLinux, Mepis, RHE 3, RH 9, Fedora Core 1, and Slackware 9.x & 10 without any problems, but as I say, there's nothing wrong with ncuses, just FC2's i386 base rpm build of it. Sorry to not have been more informative.
Rebuilt htop 0.3.3 on FC2 with latest ncurses-- can't seem to find anything wrong with it. As it seems to work on the latest ncurses-5.4-5 from yum, marking as fixed in current release.
Great Adrian, sorry for the trouble. You can view the old screen shot here: http://fury.techell.com/htop033_xterm.png Puzzling, must have been a personal problem on my end. Thanks again.
There's an annoying little home/end problem fix that will go in the build today, which will revert (sigh) yet again the terminfo custom defs for red hat, so this will need to be retested... but i will make sure that htop is one of the apps that behave well with the new change.
Changing terminfo entries is slow work. I spent about a day in the past week working on the new entries for xterm, only to find that I'll have to work around some bugs in screen (3.09.13) that I'd forgotten.
