syntax problem with noclean option for rpmdrake urpmi /var/cache/urpmi/rpms


Hello,

I am failing to keep rpms in /var/cache/urpmi/rpms (after install)
in Mandriva 2005LE while using the GUI rpmdrake / mandrake update.
(I am not using the CLI, not planning to at this stage.)

I have tried 3 things so far:

In /etc/urpmi/urpmi.cfg I added in the first section inside the {}
noclean:1
[edit] I also tried post-clean:0 and post-clean: off [edit]

I have seen only one web reference to typing
no-clean (I have not tried)
man urpmi.cfg is not clear whether one can use a noclean option.
It only states that
"Control cache management for urpmi, default is only post-clean activated".
Anyhow I struggle with the syntax here. Anybody knowing what syntax is ok?

I edited bashrc and added alias urpmi="urpmi --noclean"
This was still not working, i.e. rpms deleted automatically.
[edit] In contrast, I tested the commandline urpmi somepackage does
keep the rpms in in the cache [end edit]

So I also edited the perl /usr/sbin/urpmi
and set (if I remember well)
our $noclean=1 (instead of 0 for the default option)

I have no luck so far. What am I doing wrong?
(the post-clean option is indeed activated, I checked keeping an eye on /var/cache/urpmi/rpms)

Thanks. Regards

solved
After doing some more googling
http://hulllug.principalhosting.net/...p/t-27490.html

I edited /usr/sbin/rpmdrake
There was only one occurence of post_clean_cache
so it was easy to change the parameter from "1" to "0"

I quote from the link above:
<<the only way to get the graphical tool to keep the cached RPMs is to patch
/usr/sbin/rpmdrake>>

<<Note that the urpmi alias only has an effect if you install RPMs using
urpmi, that is if you install RPMs on the command line. The graphical
tool doesn't use urpmi but the underlying perl module. That is, both
urpmi and rpmdrake are frontends to the urpm perl module>>

This is all very clear now.
Shame I trusted some readings around cleaming that
rpmdrake was a front-end to urpmi. Without looking into
the code further and from my experience with aliases
of urpmi the quote above really does sound true (must be then :-)

Hoping this thread will help some other users

Some more keywords relevant to this topic:
save RPMs installed by urpmi or rpmdrake
directory gui Graphical User Interface
Mandrake Control Center (MCC)

Thanks for the feedback

By the way once you get use to the command line, rather than drakrpm,
urpmi --noclean (in command line is a good one)

My posts above were for 2005 limited edition, but I can confirm it
still works with mandriva 2006 free.

One last thing, if you update your rpms for security/updates,
there are sometimes new drakrpm packages (drakxtools usually).
Once you have updated drakxtools.rpm (or whatever it is called),
do not forget to edit again /usr/sbin/rpmdrake

Another thanks Emmanuel
Changed rpmdrake

However a question - also noted a perl script rpmdrake-remove
Has the same constant (post_clean_cache) set to 1
Should this be changed also?

I do not know. Good question.
Choose a very small rpms (like unzip or whatever) and do trial and errors
(and look at the behaviour)
It depends on what you want to achieve

rpmdrake-remove is usually not taking the rpm from the cache, anyway.
Maybe I am wrong.

Note also that when using rpm -e there is the repackage option
so you can make an rpm of what your are removing

Let us know what your findings are

If you want to keep the cache full then drarpm should look like this
(well this is the way I do it for 2007)

cat /usr/bin/drakrpm | grep clean
update_sources($urpm, noclean => 1, banner => $::isEmbedded);
clean_all => 0,
post_clean_cache => 0,

Yes it is different so it does not work.
When starting drakrpm from command line
and adding a package the terminal display some messages about removing files (from the cache AFAICrecall)
So I tried to grep "removing" from the perl library *.pm in one folder to locate the code, but I must be looking at the wrong place.

Smile mandriva 2007.1 spring howto keep urpmi cache full

Found a solution:

urpmi -v rgrep
rgrep -irl "post_clean_cache" /usr/lib/perl5/*
rgrep -irl "removing installed rpms" /usr/lib/perl5/*
You find out that this is where the action is
/usr/lib/perl5/vendor_perl/5.8.8/urpm/install.pm

there comment this line
#if (@l == 0 && !$options{test} && $options{post_clean_cache}) {
and replace it by
if ( 0 ) {

Ok not pretty but it works (also I think it forces urpmi not to clean the cache, not only drakrpm)

You can play with a small packet like xwininfo (24 kb) for install / removal
until it stays in the cache (check with this line:
ls -l /var/cache/urpmi/rpms/
