Jim Warner 3881a0844a old library: just some tweaks for transition to newlib
A few minor changes are being made to position the old
readproc logic for a transition to the newlib pid api.

These changes will not impact current users beyond the
the need to recompile such code. Hopefully this should
be very last version change to the deprecated library.

. most char arrays were replaced via char * to dynamic
memory. this was done so that newlib could just assume
ownership of such strings without using a strdup call.

. former user and group name arrays also became char *
but here the reason was because pwcache already cached
those names. so, copying to an array never made sense.

. the concept of QUICK_THREADS used to avoid duplicate
overhead for string data was disabled. it could not be
integrated with the newlib design, at least initially.

. any #define which influenced the size of that proc_t
was disable in the header. it was probably a poor idea
to approach optional features in such a manner anyway.

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 distributions 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.
