Jim Warner b0adacf1ea top: if line editing, account for invisible characters
If we're deleting a character or operating in overtype
mode, we must account for the potential of 'invisible'
characters. When one follows any character about to be
deleted or replaced both multi-byte sequences must go.

Without this change, there exists the possibility that
top might report some error where no error is apparent
to the user. For example, with 'other filtering' (o/O)
the user could see "unrecognized field name 'COMMAND'"
where the quoted column name appears perfectly normal.

Or maybe a sequences like the 'combining acute accent'
gets applied to an existing character instead of being
deleted as one expects when its parent was eliminated.

So, henceforth whenever any character is being deleted
we will now check for a following 'invisible' sequence
then eliminate it along with that preceding character.

[ admittedly, these scenarios are very rare yet they ]
[ may occur, especially when recalling some previous ]
[ multi-byte strings for editing. and, since we will ]
[ be interacting with a user, performance won't be a ]
[ factor so extra checks for a zero wcwidth is fine. ]

build status procps

procps is a set of command line and full-screen utilities that provide information out of the pseudo-filesystem most commonly located at /proc. This filesystem provides a simple interface to the kernel data structures. The programs of procps generally concentrate on the structures that describe the processess running on the system.

The following programs are found in procps:

  • free - Report the amount of free and used memory in the system
  • kill - Send a signal to a process based on PID
  • pgrep - List processes based on name or other attributes
  • pkill - Send a signal to a process based on name or other attributes
  • pmap - Report memory map of a process
  • ps - Report information of processes
  • pwdx - Report current directory of a process
  • skill - Obsolete version of pgrep/pkill
  • slabtop - Display kernel slab cache information in real time
  • snice - Renice a process
  • sysctl - Read or Write kernel parameters at run-time
  • tload - Graphical representation of system load average
  • top - Dynamic real-time view of running processes
  • uptime - Display how long the system has been running
  • vmstat - Report virtual memory statistics
  • w - Report logged in users and what they are doing
  • watch - Execute a program periodically, showing output fullscreen

Reporting Bugs

There are a few ways of reporting bugs or feature requests:

  1. Your distribution's bug reporter. If you are using a distribution your first port of call is their bug tracker. This is because each distribution has their own patches and way of dealing with bugs. Also bug reporting often does not need any subscription to websites.
  2. GitLab Issues - To the left of this page is the issue tracker. You can report bugs here.
  3. Email list - We have an email list (see below) where you can report bugs. The problem with this method is bug reports often get lost and cannot be tracked. This is especially a big problem when its something that will take time to resolve.

If you need to report bugs, there is more details on the Bug Reporting page.

Email List

The email list for the developers and users of procps is found at http://www.freelists.org/archive/procps/ This email list discusses the development of procps and is used by distributions to also forward or discuss bugs.
