This commit is an unrequested outgrowth of the earlier change dealing with summary area memory field scaling. That user selectable scaling provision is now extended to include 6 (at present) task oriented memory fields. The new companion 'e' (lower case) interactive command has been added and, like the 'E' command, it can cycle each of the currently displayed memory columns between KiB through TiB. There are, however, some differences. Where '+' indicates summary area truncation at a given radix, task memory fields are automatically scaled for their column. Thus, not all rows use the same scaling. And, while summary area field widths were not changed, the task memory columns were widened in order to offer more meaningful data when the radix was increased. The precision is automatically increased in step with each radix: MiB displays 2 decimal places, GiB 3 and TiB 4. To compliment that additional precision, both the %CPU and %MEM fields were widened by 1 column and now offer precision up to 3 decimal places. But, unique to %CPU, widening could already have occurred due to the number of processors in some massively parallel boxes. At any rate, total extra width for both memory and percentage fields could amount to twenty (precious) columns more. So for both the memory and % fields the original width (along with loss of precision) can be restored via new compiler conditionals which this commit also provides. p.s. and it will be rcfile preserved for any restarts! (now that we know a '.' + 2 spaces is squeezed to one) (everything's perfectly justified, but it's just luck) Reference(s): http://www.freelists.org/post/procps/top-regression-reports 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.
