Hi list,

I never saw this anywhere before, so I'd like to ask here first, before
doing so

Is it allowed to create a file ~/.mpd.conf, when building in koji and
deleting afterwards?

I need to write down a password into that file, for running a testsuite.
If that file does not exist, I can't run mpich2 tests.

Here is the snipped, I intend to use:
"""
%{_mpich2_load}

# create ~/.mpd.conf, if it does not yet exist
if [ -e ~/.mpd.conf ]; then
# working locally, don't delete ~/.mpd.conf
DONT_DEL="TRUE"
else
DONT_DEL="FALSE"
echo MPD_SECRETWORD=$(pwgen -s 50 1) > ~/.mpd.conf
chmod 600 ~/.mpd.conf
fi

mpd --daemon
PYTHONPATH=%{buildroot}%{python3_sitearch}/mpich2
python3 test/runalltest.py
mpdallexit

# delte ~/.mpd.conf again
if [ $DONT_DEL = "FALSE" ]; then
rm ~/.mpd.conf
fi

%{_mpich2_unload}
"""

This prefectly works with my local rpmbuild and local mock and there
won't probably be an issue with that, but is this 'the safe way' to do?
(This also use my local ~/.mpd.conf and does not owerwrite it or deletes
it afterwards.)


Thanks in advance.

Thomas

There also is a safer way...

"""
echo MPD_SECRETWORD=$(pwgen -s 50 1) > mpd.conf
chmod 600 mpd.conf
export MPD_CONF_FILE=mpd.conf

<run tests here>

rm mpd.conf
unset MPD_CONF_FILE
"""

I'll use that now. But would be still interesting, if the other
possibility would be allowed...

It is not allowed:

Nice. Could you document this on the wiki somewhere? This could be useful
for folks who want to run some testsuites which use mpich2. Could you
prepare something similar (i.e. MPI environment setup) for openmpi?
For example, currently I have the testsuite in freefem++ disabled,
but I'd prefer to keep it enabled if I can.

Regards,
R.

This is totally unrelated to your question, but could you consider not using
double negatives for this variable? It makes the script harder to read, IMHO.

Well, I could use KEEP and not DONT_DEL maybe, but now I use a different
snippet, because mpich2 allows any file to be the config file, so now I
create it just in the same directory './mpd.conf'.

Sure, I thinkt he best place atm would be MPI packaging guidelines [1].
I'll ping the writer of that and maybe it's added there.

Just create a proposal and send it to the FPC for discussion.

If the proposal goes through both in the FPC and FESCo, maybe the MPI
guidelines will finally be moved among the other guidelines; they were
after all approved in August 2009..

How does the technique of just setting HOME like

mkdir mytemphome
cd mytemphome
echo "STUFF" > .mpd.conf
export HOME=$PWD

fail to work for this case? The mpich2 source code suggests this should
work.

In any case, I would consider it very bad practise for package builds
or package tests to write into $HOME/.any.file.
