Description of problem: $ yum search -C jabber Loaded plugins: langpacks, presto, refresh-packagekit [Errno 13] Permission denied: '/var/cache/yum/x86_64/16/fedora/8e5f7c264cbd50659a18cd4f87fe75ea728fdc187d4e5e041898070c9dccf5e8-comps-f16.xml' $ ls -l /var/cache/yum/x86_64/16/fedora/ -lZ -rw-r--r--. root root unconfined_u:object_r:rpm_var_cache_t:s0 8e5f7c264cbd50659a18cd4f87fe75ea728fdc187d4e5e041898070c9dccf5e8-comps-f16.xml 'yum search' without the -C option works fine. Also, this used to work on F15. After the upgrade to F16, this stopped working.

Comment 3 Zdeněk Pavlas 2011-11-30 06:31:24 EST
749239 is a bug in error handling of this bug, but really a separate issue. Reopened that- sorry for the notification noise.

just don't use the -C option? given how caching and user-local copies of the repodata have evolved -C is not very much needed

If things aren't supposed to work this way, maybe some config change is needed, (this is an installation that's been upgraded from previous releases, not a new install)?
Comment 6 Zdeněk Pavlas 2011-12-01 02:55:06 EST
This bug is caused by different handling of group_gz metadata files in Yum and Yum-langpacks. Yum downloads and keeps the .gz file, opening it with gzip.open(). But Yum-langpacks tries to decompress it to the same (often rdonly) directory. Possible fixes are: a) change yum such that it prefers .gz file for download but unpacks it immediately after the download. b) change yum-langpacks to use in-place decompression.
Comment 7 seth vidal 2011-12-01 09:35:18 EST
Without -C it's not downloaded each time. For the user it is copied from the most recent copy of the systemwide yum cache. If that copy is current enough then it is used, if not new one is fetched.

Example use-cases 1) when I'm on mobile broadband, I just want to query the db for a particular package or look up its info. In that case, I don't want to use up any bandwidth or incur charges just for querying the db. 2) When I get an rpm from some source (e.g. latest kernel from koji), I want to just 'yum install -C ./kernel*.rpm' without having to fetch latest metadata.
Comment 9 Zdeněk Pavlas 2011-12-15 06:14:24 EST
I think this should be fixed in langpacks.py, patch added.
Comment 10 Zdeněk Pavlas 2011-12-15 06:15:27 EST
Created attachment 547184 [details] Use the already decompressed comps file.

Thanks, applied to git.
