procps-ng
Summary
Migration from legacy procps tools to procps-ng (next generation procps tools).
Owner
- Name: Jaromir Capik
- Email: jcapik@redhat.com
Current status
- Targeted release: Fedora 18
- Last updated: 2012-03-07
- Percentage of completion: 100%
Detailed Description
Old (legacy) procps tools had no updates for several years and that led to a massive code split caused by a local-only application of distribution specific patches, which were not merged upstream. The project became hardly maintainable since some of the newly written patches were incompatible with sources maintained by other distributors. A similar incompatibility could be noticed in the applications behaviour and their command line switches. This inevitable update can be understood as an effort to unify the procps tools across all Linux distributions.
Benefit to Fedora
Better maintainability, lower resource consumption, NLS support, many bugfixes and improvements (see the changelog below).
Scope
Even if there are more then 30 packages depending on the procps tools, the change shouldn't have major negative impact on the dependent packages.
How To Test
No special hardware is needed. Automated test suite is not available yet (even if it is needed), but all the commands should behave according to the man page. Usually just basic operations need to be tested, since it's very ineffective to test all the features manually due to the complexity of the tools.
User Experience
No major changes expected.
Dependencies
The following packages depend on the procps/procps-ng package and might be affected by the migration:
autofs backup-light bwm-ng cloud-init cone cups-pdf egd environment-modules gearmand hail initscripts jed ksh libguestfs libqb make munin-node mysql net-snmp olpc-netutils parprouted parrot perl perl-IO-Socket-SSL perl-Proc-PID-File pcp readahead redhat-lsb resource-agents rkhunter ruby rusers system-config-users tabled tog-pegasus tomcat tomcat6 wallpapoz
Contingency Plan
None necessary

Release Notes
procps-ng-3.3.1 --> procps-ng-3.3.2

any supported languages.
* Imported a bunch of distribution patches:
watch: support unicode
watch: add precision wait time option -p
watch: interpret ANSI color code sequences
watch: add -exec and -beep flags and has better quoting
w: use environment to set user and from/host column widths
w: use COLUMNS environment if TIOCGWINSZ fails
w: bassman emulation with -o option
vmstat: do not scale si/so just like bi/bo
libprocps-ng: sysinfo.c: truncate the vmstat figure to 32 bits
tload: remote unneeded optarg and optind variables
sysctl: fix up some option processing
skill: kill prints perror
skill: do not treat skill null parameter as 0
skill: fix too greedy option parser
libprocps-ng: readproc.c: some type conversion help
ps: rename SZ to SIZE
ps: add sorting to %mem for ps
pmap: provide information for -x option
pgrep: distinguish between invalid commandline parameters and '-?'
pgrep: fix compiler warning saved_start_time might be used uninitialized
pgrep: add -c option for counting number of matched proceesses
pwdx & libprocps-ng: Hurd does not have MAX_PATH defined
ps: --sort does not work with time argument
skill: add CR to warning line
contrib: minimal ps: define mips PAGE_SIZE
libproc-ng: prettyfy proc mount messages
ps: add build option to disable ps option warning
libproc-ng: support building without WCHAR support
sysctl: remove index() for buildroot
* top now has a search capability
* User import is validated better to stop negative values for intervals etc
