This patch will cure a potential aberration associated with a terminal's size (SIGWINCH) and top's new graphs modes. The symptoms were a dangling tilde (~) plus the potential loss of a graph's right-most visual content. The condition was only apparent when a %Cpu approached 100% usage. Also the apparent loss of content affected the 'block' graph only. With 'bar' graphs, that affect became the loss of proper right-most bar graph colors. The cause was determined to be a combination of: 1) an unnecessary snprintf precision specification; and 2) a rounding quirk for any graphs which displayed distinct types of information (as for user/syst, used/unavail). These could then combine to produce an extra bar/block which, in turn, resulted in the truncation of a pseudo termcap attribute used by the show_special() function. What was originally interpreted as an intractable race condition turns out to be just a self inflicted wound.

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.
TRANSLATING MAN PAGES
There is a three-step process for translating man pages. Most
of the work happens in the man-po directory.
make -C man-po translate-templates
Creates the translation templates (the .pot files) for translators
to use as a base. These, along with the tar file, should be sent
to the tp-coorindator before release.
make get-trans
rsyncs the latest translated (.po) files for both the programs and
man pages.
make -C man-po translate-mans
This is also called in the dist-hook and is where the translation
magic happens. Take the original man page, the relevant .po file
and produce a translated man page in that language.
All of the man pages generated are found in
man-po/(LANG)/man(SECTION)/
