Library changes
readproc
. added support for supplementary groups
. eliminated 2 potential mem leak sources
. shortcut used for multi-threaded str
vectors & ptrs was obsoleted
. freeing of proc_t related dynamic
memory now rests with the library
. standardized/normalized many c comments
sysinfo
. corrected note regarding glibc & cpuinfo
library.map
. made the visible freeproc accessable
Program changes
pmap
. initialized buffer for new readproc i/f
. eliminated now obsolete free() call
ps
. added width aware supgrp support
. initialized buffers for new readproc i/f
. eliminated now obsolete free() calls
top
. added supgrp support as variable width
. eliminated now obsolete free() calls
. expoilted library freeproc function
. corrected -h|v args text & spacing
. updated some c comments
Documentation changes
ps.1
. added supgid and supgrp
top.1
. added supgid and supgrp
. addition of above required renumbering
many fields in section 3a. DESCRIPTIONS
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

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'
