Hi Craig, The attached tarball contains 6 patches for top. I hope they'll be pushed more promptly than the last bunch. ---------------- Hi Jaromir, These changes address the two issues you raised back on January 8: 1) retain current context through window resize 2) ignore repeated SIGWINCH with overzealous window managers The first issue was relatively easy and now top's context will be preserved even through a suspend/resume sequence. Thanks for prompting that improvement. I was tempted to dodge the second issue because top was just a victim. The flood of signals doesn't occur under all window managers and I knew it would be a tougher programming challenge. However, it was worth the effort. As you experiment with resize you'll discover that some keystroke is usually/always required afterward to produce an updated display. My revised man document now suggests using an innocuous key like a punctuation character or cursor motion key. Personally, I always use the <Left> arrow key as the most natural choice. I can find no way around this requirement after suppressing SIGWINCH. Even with signals unrestrained that extra keystroke is sometimes required. Part of the problem is doubtless due to the emulator, like Fedora's gnome-terminal. There are internal buffers for optimization (as with top) and scrolling plus there is often an emulator preferred way of presenting resized results (unlike top). Sometimes top's view of screen contents differs from the emulator's view. Lastly, please try top with the new OFF_SIGWINCH enabled. That will restore the flood of signals but it also means an extra keystroke is generally not necessary. This is most visible on the Fields Management screen where immediate response to SIGWINCH produces some interesting effects as the window grows and shrinks. You may find that with context now preserved, repeated signals and immediate response is preferable to that extra keystroke requirement. If so, I can change the default behavior. Just let me know which you prefer. Regards, Jim ps. Use the 'reset' command before any new test for the most reliable results.
