Bug 19382

That was caused by testing different expressions in urpmi skip.lst
Just tried to avoid installing plasma 5.7.95 packages on the basis of version number.
Removing that "incorrect" expression from skip.lst makes drakrpm to start OK again...

Can you attach the incorrect skip.lst file? That could help debugging the issue so that we can help drakrpm better react to such situations.

Just the default file + the following line:

/*-5.7.95*/

BTW is there documentation how to make rules for skip.list and is it possible to create a rule on the basis of version number at all?

from the man page (man urpmi.files):

       /etc/urpmi/skip.list
           The list of packages that should not be
           automatically updated when using
           --auto-select. It contains one package
           expression per line; either a package name,
           or a regular expression (if enclosed in
           slashes /) to match the name of packages
           against. (Actually, it's matched against the
           full name of the package, which has the form
           name-version-release.arch.)


Please try again with just 
    
     /-5.7.95/

in the skip.list

That works fine, by the way, but it might, of course, also make you skip a possible package with e.g. "-547195" as part of a very long git version.

So escaping the dots and doing "/-5\.7\.95/" is better.

The "*" in your string didn't work, because there it's about having the previous character 1 or more times. There was no previous character for the first *, so it failed.

Keeping this report open, because I think it would be nice to add more valid examples to the skip.list file.

(I doubt preventing a Plasma5 upgrade will work easily with adding the matching versions to the skip list, though, unless you keep an eye on the changelog mailing list and block the versions of about anything neoclust pushes  ;-) )

Summary: drakrpm crashed because of malformed skip.list => drakrpm crashed because of malformed skip.list - it would be nice to have more valid examples in that file
Severity: normal => enhancement

2016:09:22:16:40 < stormi> marja: to me bug 19382 is not an enhancement, it's a bug. You don't crash when you have an invalid configuration file, you throw and error.

2016:09:22:16:41 < stormi> You kind of hijacked it into an enhancement request for examples in the file

Reverting severity to normal (also because I don't manage to get urpmi to crash over a similar wrong configuration, so a rpmdrake crash seems avoidable)

Forget that, when I do exactly the same, so when I start the string to match with a *, then urpmi _quits_, after as good as the same message about "Quantifier follows nothing in regex"

the only thing I don't get is a backtrace :-þ

Thanks Marja for sharing knowledge!
However, I "pulled the plug" and upgraded to Plasma 5.8 beta - no regrets so far... :)
