André Carvalho b7b66b76a5 Adds support for linux delay accounting (#667) 
Adds support for showing columns with linux delay accounting.

This information can be read from the netlink interface, and thus we set up a socket to read from that when initializing the LinuxProcessList (LinuxProcessList_initNetlinkSocket). After that, for each process we call LinuxProcessList_readDelayAcctData, which sends a message thru the socket after setting up a callback to get the answer from the Kernel. That callback sets the process total delay time attribute. We then set the delay percent as the percentage of time process cpu time since last scan.

Hisham Muhammad 9487bda330 Do not use xSnprintf when the result is used. Fixes #662. 2017-08-01 15:48:43 -07:00
Hisham Muhammad 09e241fb12 Security review: check results of snprintf. 
Calls marked with xSnprintf shouldn't fail.
Abort program cleanly if any of them does.

Hisham Muhammad e940aecfb9 Add "no perm" status when other fields fail due to lack of permission. 
Thanks @Sworddragon for the heads up.
See #88.

Hisham baec4bdcb0 Try to retain last full name of a zombie process. 
Once a process goes zombie on Linux, /proc/PID/cmdline
gets empty. So, when we detect it is a zombie we stop
reading this file.
For processes that were zombies before htop started,
there's no way to get the full name.
Closes #49.

Explorer09 6dae8108f8 Introduce CLAMP macro. Unify all MIN(MAX(a,b),c) uses. 
With the CLAMP macro replacing the combination of MIN and MAX, we will
have at least two advantages:
1. It's more obvious semantically.
2. There are no more mixes of confusing uses like MIN(MAX(a,b),c) and
   MAX(MIN(a,b),c) and MIN(a,MAX(b,c)) appearing everywhere. We unify
   the 'clamping' with a single macro.
Note that the behavior of this CLAMP macro is different from
the combination `MAX(low,MIN(x,high))`.
* This CLAMP macro expands to two comparisons instead of three from
  MAX and MIN combination. In theory, this makes the code slightly
  smaller, in case that (low) or (high) or both are computed at
  runtime, so that compilers cannot optimize them. (The third
  comparison will matter if (low)>(high); see below.)
* CLAMP has a side effect, that if (low)>(high) it will produce weird
  results. Unlike MIN & MAX which will force either (low) or (high) to
  win. No assertion of ((low)<=(high)) is done in this macro, for now.

This CLAMP macro is implemented like described in glib
<http://developer.gnome.org/glib/stable/glib-Standard-Macros.html>
and does not handle weird uses like CLAMP(a++, low++, high--) .

Apparently a line longer than 255 chars was spotted in the wild:

Hisham Muhammad a84aa2e782 Cached memory calculations, take 2. 
Thanks to @OmegaPhil for discussion and reviewing.

Hisham Muhammad 5bc1f5ed04 Account unreclaimable slab and shmem as used memory, 
reclaimable slab as cached memory.

Hopefully this presents a more truthful representation of
available vs. used memory on Linux.
