Package: swish++
Version: 6.1.5-1
Followup-For: Bug #459611
Testing the new package with 'rlimit'. Opinions & observations:
1) 'rlimit' should be executable and in the path.
That way users don't have to keep track of it, and
the packaging system will be able to
find it, purge it, etc.
2) Even with the example given in README.Debian:
FilterFile *.pdf rlimit -t 3600 -- pdftotext %f @%F.txt
...I don't understand how to use 'rlimit' to fix 'swish++' yet.
Exactly which file should the user edit? What numbers should we
feed it? (I see that "-t 3600" sets the CPU limit
to 1 hour max; but how is one to know how much time
is enough?) How might it affect other cron jobs, should I
replace or delete any that already exist?
3) I agree with N. Ramsey; expecting users to cope with
minutiae is adding another point of failure.
4) 'rlimit' as a pipe-ready 'ulimit' wrapper util seems like a
good idea, and may be useful enough that it belongs in some
other general purpose package. Perhaps its own package,
or thrown in with 'moreutils', 'cpulimit', or something
appropriate.
5) 'rlimit' is still rough around the edges:
% rlimit --help
exec: 22: help: not found
...and code like:
[ -n "$cmd" ] || exit 0
Should the exit code be "0" if there's no command? Looks
like an error, unless I missed the point.
Calling '/bin/sh' might be unreliable, as different shells
do 'ulimit' differently, i.e. more flags in 'bash' than
'dash', etc.
6) Some kind of 'rlimit' before/after benchmark or example,
the kind that anyone can test, (not system critical),
would be good.
Thanks for writing this interesting little util.
HTH...
