We're assuming that all Linux consoles preserve color, of course. Repainting the screen (Ctrl-L) is likely to exercise different paths in the screen optimization. Normally ncurses will jump from one part of the screen (top-to-bottom, left-to-right) updating the parts that have changed. When repainting, there's no jumping (except over blank areas that are known to be in the "right" color). Comparing the xterm and linux terminal descriptions, I see one detail to investigate: the linux description says it uses padding characters (npc is missing, hence false), and it (like xterm) implements flash (which uses a time-delay). I recently modified the way the npc data is stored, and (though it's working for me), it may be the problem. To check this, I'd run with a modified "linux" terminfo which adds the "npc" flag, telling ncurses to not try to use padding characters. My hunch here is thinking that alert messages from yast2 could be making it write padding characters - and if there's some bug in that area, it could write unexpected text to the screen. (if it's not that simple, I'll think of something else). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

In other words there is something which cames from the new headers of 5.6.20080804 and influence even if the shared libraries are replaced with the old ncurses 5.6.20070128. Only removing `bce' (screen erased with background color) in the terminfo entry linux seems to help. But this makes screen refresh slower. The question remains: Which interface in curses.h/panel.h is used in such a way that it influence even if the old library is used. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The corresponding library would be source-compatible, but not binary-compatible (so I don't think you would be accidentally linking successfully). curses declares several global variables. In this special case, ncurses replaces the variables with the return value of functions (such as _nc_COLOR_PAIRS). The reason for doing this is to limit the ways an application could manipulate the data in a threaded application. Briefly - I moved most of the non-public data (the ones beginning with "_nc_") into the structs in lib_data.c, then added the optional feature NCURSES_OPAQUE to disallow access to WINDOW struct-members. That much is binary-compatible (unless I made an error). I added functions to allow set/get of the WINDOW struct-members (which so far few programs use). Then I added the pthread-specific wrapping of variables. In some cases, this let me make some of them reside only in the SCREEN struct (which is a potential place for behavior change). However, in the normal library configuration, these are still global variables. It's possible that some logic change crept in though. When pthread is configured, NCURSES_OPAQUE is always defined for applications - which let me change the NCURSES_SIZE_T to an int - potentially allowing huge PAD's. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I was just comparing my current ncurses/curses.h and ncursest/curses.h, and saw only the details related to the NCURSES_OPAQUE and the wrapping of global variables. I've been replacing my system ncurses libraries regularly - and on the older installs, those just plug in without recompiles of lynx, etc. (For Debian/testing, they're tracking about a month behind, so the /usr/include/curses.h does move along, possibly obscuring a header-change). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

(I don't think so - I've done some repairs on the scripting, but the lib_gen.c file should be comparable across releases - differences would be fairly easy to analyze). A functional change for bce would be related to the way color information is set/copied/extracted from the cells - that's not close to lib_gen.c The cell _size_ (cchar_t, etc) would also be a place to look. But if that changed unexpectedly, I'd guess all of the colors would be broken. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Commit 93f78da405685a756beeaeae4b5e41fcec39eab3 has been committed upstream to revert the original patch mentioned in comment #21. In this commit Alan Cox is referenced as follows regarding the original patch: "Unfortunately it's wrong and its been causing breakages because various apps like ncurses expect our previous (and correct) behaviour." Werner: Do you want to try an 11.1 kernel with this patch reverted, else do you have a easy test case (ideally not involving yast) that I can use to confirm it'll fix the issue? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

One needs to run "yast disk" as root on the console. But as I tried that on 11.1, I could not reproduce the bug. It is because yast2-ncurses-2.17.8 includes the patch from comment 20. Bubli tried that with the patch removed and the bug was not present either.

This was just a standard kernel from the distribution (11.1 GM, pae flavour) and I doubt it contains the patch in question. In other words, it seems to work even without it. Or maybe it doesn't and I simply did not run into the bug because I don't know how to test.

For testing you require a physical terminal and a local virtual console thereone (not with ssh or similar as this is to slow).

Hm, but I did not try Tony's kernel from comment #35
These kernels have unfortunately been auto-deleted (too much time has expired).
It definitely does *not* work, as I've seen this effect live.
The commit referenced in comment #33 is not in either SL111 or SLES11 kernels. If someone can reliably reproduce, perhaps YOU WOULD BE WILLING to try a kernel with the updated patch. I can rebuild them. Otherwise, I'll setup a SL11.1 system and see if I can reproduce. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I have built and installed yast2-ncurses-2.17.7 which doesn't contain Werner's patch and have called a YaST module, e.g. 'yast language'. The result is that the black artifacts are here again. This is the expected result if the commit mentioned in comment #33 is not in the SL11.1 kernel (as you mentioned above). Could you please provide a kernel with the patch reverted.

The only effect of Werner's patch (setting 'back_color_erase' to FALSE) is that drawing on linux console is a little bit slower. But this shouldn't be noticeably for textmode YaST.
