top: squashed 'scale_tics' catch-up for Ctrl-E scaling
[ the original newlib commit message(s) appear below ] ---------------------------------- newlib patch #1 --- top: refactor 'scale_tics' function for better scaling This patch refactors the 'scale_tics' function to more closely parallel uptime shown on the first line of the summary area. The old logic has been preserved through the header file's new #define SCALE_FORMER provision. However, the former logic was actually a big disaster. These are some potential problems with that old logic: 1. With respect to our time fields top no longer deals solely with cpu time. So, the old limits of '68 weeks' could possibly be insufficient to reflect those times. 2. Given the widths of top's new time fields, the code never got beyond scaling to hours. For example, with a ridiculously large span of 19 years, the scaled result would then be shown as '167832h'. We never reached the days ('6993d') or even the weeks ('999w') equivalents. 3. Similarly, with that 'TIME+' field and a large tics value, results would then appear as 'MMMMMM:SS' rather than the more meaningful 'HH:MM:SS' or days and hours. So henceforth we will adopt these scaling conventions: MMM:SS.hh ... minutes:seconds.hundredths MMM:SS ...... minutes:seconds HH,MM ....... hours,minutes D+H ......... days+hours (with 'd' & 'h' suffixes) D ........... days (with 'd' suffix) W+D ......... weeks+days (with 'w' & 'd' suffixes) W ........... weeks (with 'w' suffix) Note that, unlike our former scaling logic, that 'MMM' portion won't be allowed to grow unconditionally. It's limited (arbitrarily?) to 360 total minutes (6 hours). Additionally, the 'HH' guy will be limited to 96 hours (4 days) while that 'D' limit was set at 14 (2 weeks). Whenever a limit is hit, scaling will advance a level. ---------------------------------- newlib patch #2 --- top: extended 'scale_tics' function for Ctrl-E scaling That normalization of the 'scale_tics' function in the prior commit convinced me that I won't please everyone with my arbitrary choices for the scaling transitions. So, this patch will provide the users with a means for setting their own scaling transition points with a new toggle. Ctrl-E was chosen since the 'e/E' toggles were already present as a means of scaling (albeit memory). [ this toggle will also serve an educational purpose ] [ by allowing one to see all the scaling conventions ] The scaling a user establishes is saved in the rcfile. ---------------------------------- newlib patch #3 --- top: enhanced 'scale_tics' function for Ctrl-E scaling When scale_tics was refactored and then Ctrl-E support added to top, the complete range of scaling values was not visible. Namely, a single 'd' (days) & 'w' (weeks) was never seen with ^E. With this commit they will be. Signed-off-by: Jim Warner <james.warner@comcast.net>
