Version: 1:2.9.7-1
Usertags: pidof-without-procps
Dear maintainer(s) of linuxcnc,
it appears that linuxcnc 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 linuxcnc
that use `pidof` at runtime;
* via the `Build-Depends:` field of linuxcnc, 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 linuxcnc, 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 linuxcnc uses `pidof` due to the following
code snippets:
```
path: linuxcnc_1:2.9.7-1/src/configure.ac
fi
AC_PATH_PROG(PIDOF, pidof, "none", $SPATH)
if test $PIDOF = "none"
then
path: linuxcnc_1:2.9.7-1/src/configure.ac
if test $PIDOF = "none"
then
AC_MSG_ERROR([pidof not found])
fi
path: linuxcnc_1:2.9.7-1/tcl/tooledit.tcl
# Note: pidof ignores defunct processes
# catch required since child error returned if no other pids:
catch { set tooledit_pids [eval exec pidof -x -o[pid] tooledit]} emsg
# determine if axis is running with same filename
path: linuxcnc_1:2.9.7-1/tcl/tooledit.tcl
set tooledit_pids ""
# count howmany tooledits (exclusive of this one) are running
# Note: pidof ignores defunct processes
# catch required since child error returned if no other pids:
catch { set tooledit_pids [eval exec pidof -x -o[pid] tooledit]} emsg
```
Feel free to close this issue if this is a false positive (for example
if this code is in an unreachable code path).
Regards,
