No top #define is enabled and that constitutes default behavior. So whenever a default behavior should change the define must be changed too if it is to remain off. This commit simply changes top's default behavior with respect to allowing/suppressing any potential flood of SIGWINCH during resize operations, if running under X. Formerly top would block those signals to reduce costs of repeated refreshes. That yields a requirement where the user would have to provide another keystroke for a final display update. That keystroke may not always be needed now, but it ultimately depends on some terminal emulator's scrollback buffer. In any case, the cost of re-sizing may go up a bit, under most window managers. (everything is perfectly justified plus right margins) (are completely filled, but of course it must be luck) Reference(s): commit 4f33b6b8c56464b4044deb29a3bb0e32622e108f http://www.freelists.org/post/procps/top-won-the-sigwinch-war http://www.freelists.org/post/procps/top-won-the-sigwinch-war,4 http://www.freelists.org/post/procps/top-won-the-sigwinch-war,5 Signed-off-by: Jim Warner <james.warner@comcast.net>
COMPATIBILITY This code is intended for use with Linux 2.6.xx, 3.x and hopefully all future kernels. INSTALLATION If you are using git version of the project you need extra step. ./autogen.sh After that, and everyone using .tar.xz version of procps-ng, can do normal build. Read './configure --help' to select options for your needs. ./configure make make install If you have DejaGNU installed you can run optional test suite. make check HOW TO CONTRIBUTE See Documentation/BUGS file. PACKAGING If you are a downstream maintainer (packager) for a Linux distribution, please avoid causing troubles. This section applies to you. Avoid maintaining distribution specific patches. Send your patches to upstream, where they are at least reviewed, if not included. Please forward bug reports. If your bug database is public and busy enough to bother with, please make this known. Follow Debian's lead in making the bug database easy to comment on via email without need for an account. For normal packages, ensure that you do not add debugging flags to the CFLAGS variable.
