Bug#1136463: 3depict uses pidof but does not depend on procps

[Gioele Barabucci]

Source: 3depict
Version: 0.0.23-2+b5
Usertags: pidof-without-procps

Dear maintainer(s) of 3depict,

it appears that 3depict uses `pidof` in its testsuite, or that
at least one of its binary packages uses `pidof` at runtime.
Historically, `pidof` was provided by the Essential package
`sysvinit-tools`, making an explicit dependency unnecessary. However
`pidof` will soon be moved to `procps` and will no longer be part of
the Essential set.

Please add an explicit dependency on `procps`:

* via the `Depends:` field of all binary packages of 3depict
  that use `pidof` at runtime;
* via the `Build-Depends:` field of 3depict, if `pidof` is
  used in tests run at build-time;
* via the `Depends:` field of `debian/control/tests`, if `pidof` is
  used in autopkgtests.

To prevent any disruption for users of 3depict, please add
this dependency now, before `pidof` is moved from `sysvinit-utils` to
`procps`. Alternatively, you could remove all uses of `pidof`.

It is believed that 3depict uses `pidof` due to the following
code snippets:

```
path: 3depict_0.0.23-2/test/dogtail/test.py
	#Check for existing 3depict instances
	data=subprocess.Popen(['pidof', '3Depict'],stdout=subprocess.PIPE).communicate()[0]
	pids=data.split(' ');
	if not (len(pids) == 1 and len(pids[0]) == 0)  :
```

Feel free to close this issue if this is a false positive (for example
if this code is in an unreachable code path).

Regards,
