added output width/height override support to top, + misc
This source patch addresses the following:
Enhancements
. added -w command line switch, with optional argument
( offers complete control over width and height, in )
( combination with env variables COLUMNS= and LINES= )
. updated man document to reflect the new capability
. reengineered Fields Management to be more flexible
thus no longer requiring a normal sized tty
Buglets fixed
. forced View_SCROLL off when in 'Batch' mode
. for narrow xterm, fixed return val in show_pmt
. for narrow xterm, fixed cursor pos in linein
. added a window specific end-of-line termcap ptr
( so clr_eol does not overwrite last printable char )
Cosmetic changes
. eliminated TTYGETENVYES define, incorporated as -w
. eliminated RESIZE_LIMIT define, no longer needed
. eliminated FIELD_CURSOR define, no longer possible
. eliminated extra text on Fields Management screen
. fixed miscellaneous man document typos/formatting

enhanced libproc cgroup/cmdline support, exploited by top
Library Changes
. added PROC_EDITCMDLCVT flag
. added an internal (static) fill_cmdline_cvt function:
- reads and "escapes" /proc/#/cmdline
- returns result as a single string in a single vector
- callers are guaranteed a cmdline (no more NULL)
. added vectorize_this_str function, exploited by
fill_cgroup_cvt, fill_cmdline_cvt
. generalized read_cmdline function as read_unvectored, now
exploited by fill_cgroup_cvt, fill_cmdline_cvt, read_cmdline
( cgroup and cmdline no longer need be converted to string )
( vectors before being transformed to final representation )
. fixed bug regarding skipped group numbers (when enabled)
. escape_str made responsible for all single byte translation
with distinction between control chars + other unprintable
. added escaped_copy function for already escaped strings
. reorganized parts of proc_t to restore formatting standards
( displacement changes shouldn't matter with new version # )
. former ZAP_SUSEONLY #define now OOMEM_ENABLE
. added to library.map: escaped_copy; read_cmdline
Top Program Changes
. exploited the new PROC_EDITCMDLCVT provision
. eliminated now obsolete #include "proc/escape.h"
. changed the P_WCH display format if no kernel symbol table
. fixed very old bug in lflgs for out-of-view sort fields
. former ZAP_SUSEONLY #define now OOMEM_ENABLE
Ps Program Changes
. exploited the new PROC_EDITCMDLCVT provision
. exploited the new escaped_copy function
. consolidated pr_args and pr_comm into pr_argcom

cgroup support migrated to libproc, plus miscellaneous re-formatting
This source patchset addresses the following:
Library Extension (readproc)
. added PROC_EDITCGRPCVT flag
. added an internal (static) fill_cgroup_cvt function:
. reads AND parses /proc/#/cgroup
. returns result as a single string in a single vector
. thus no changes to proc_t structure or free memory logic
Program Enhancements (top)
. removed parse_cgroup logic in favor of libproc
. eliminated cgroup sort recurring overhead
. converted WCHAN field to variable width
. generalized variable width field logic in task_show
. real-time notation under P col more distinctive as 'rt'
Program Cosmetic (top)
. CGROUP now known as CGROUPS (plural)
. moved jan's attribution from top.c to 'Notes' in top.h
. numerous comments tweaked
Document Enhancements (top)
. documented CGROUPS field (required renumbering all fields)
. adapted narratives for the 3 current variable width fields
. expanded real-time scheduling notes, 'RT' now shown as 'rt'

free: great modernization
Support long options, use program_invocation_short_name, print
version up on request, new giga & tera byte sizes switches, exit
when numeric arguments has garbage... and for rest see the diff.

cgroup support. rcfile errors default to fatal
This source patch addresses the following:
Conceivable Buglets Avoided
. added sanity checks for previous assumptions re: pid size, num cpus
. changed response for rcfile errors to fatal, vs. silent default
Enhancements
. reorganized WIN_t struct for reduced padding and better readability
. generalized code for multiple var-width cols (divorced from pflags)
. absorbed jan gorig's cgroup patch, with attribution
Cosmetic
. reduced numerous #ifdef directives, especially in calibrate_fields

several bug fixes, enhancements and formatting
The documentation portion of the patch addresses the following:
README.top
. corrected a minor typo
. updated to reflect current patch level
top.1
. fixed potentially misinterpreted Me/ME strings
. added '.Bd -literal' directives for indented fixed-width font
. some comments changed from \# to .\" to avoid man2html problems
The source portion of the patch addresses the following:
Buglets
. header/task output length now consistent
. fixed 2 obscure horizontal scrolling bugs
. fixed potential bug regarding 'help' and 'current' window
. messages and prompts are now also sensitive to terminal width
. normalized buffer names/sizes now accommodate any SCREENMAX changes
Features
. made %CPU and 'i' mode handling more efficient
. for input the Up/Dn arrows keys act as alternatives to Ins/Del keys
. an optional USE_X_COLHDR define eliminates ALL 'x' toggle overhead
. an optional ZAP_SUSEONLY define was added for Werner's modifications
Cosmetic
. defines and format for optional end-of-job reports standardized

Read the system boot time from /proc instead of computing
Read the time of system boot from /proc/stat (entry: btime) instead
of computing it as the difference between the current time and the
uptime. This is the only way to get a consistent result which won't
possibly change from one run to the next.
The problems with the original code were:
* Both the current time and the uptime are rounded down to the second,
but the system doesn't boot on an integer second value so they do not
tick at the same moment. Thus, the rounding errors can cause a one
second difference from one run to the next.
* We can't read the uptime and the current time at the exact same moment
anyway, so the time difference we compute is bound to be inaccurate.
