[Bug 629882] New: YaST reads YCP include files 1 byte at a time
http://bugzilla.novell.com/show_bug.cgi?id=629882 http://bugzilla.novell.com/show_bug.cgi?id=629882#c0 Summary: YaST reads YCP include files 1 byte at a time Classification: openSUSE Product: openSUSE 11.3 Version: Final Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: YaST2 AssignedTo: mvidner@novell.com ReportedBy: mvidner@novell.com QAContact: jsrain@novell.com CC: kmachalkova@novell.com Found By: Development Blocker: --- In discussing another bug(*), Bubli mentioned that strace output was full of lines like
[pid 8194] read(7, "b", 1) = 1 [pid 8194] read(7, "u", 1) = 1 [pid 8194] read(7, "s", 1) = 1 [pid 8194] read(7, ";", 1) = 1 which clutters the output and makes stracing, if not regular runs, much slower.
It turns out that for certain files, ones pulled in by the YCP include statement, input buffering is not enabled. *) http://lists.opensuse.org/yast-devel/2010-08/msg00012.html -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It is very little work for me to make an 11.3 update. The yast2-core behavior is present since SLES9, but applying the patches there would be more work. I think we should make an update for 11.3, with low priority. If that's OK, please give me a Swamp ID. -- 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.
