Red Hat Bugzilla – Bug 1022028
package count doesn't match with actual packages in repodata
Last modified: 2014-09-09 05:11:08 EDT
+++ This bug was initially created as a clone of Bug #1022001 +++
How to reproduce:
1) create a file list with existing packages
2) append a line with package that does not exist
3) run $ createrepo -i <package-list> .
zegrep '<package |packages=' repodata/*primary*xml*
<metadata xmlns="http://linux.duke.edu/metadata/common" xmlns:rpm="http://linux.duke.edu/metadata/rpm" packages="3">
Header says 3 packages while there are just 2 of them in metadata.
We'd like to create XML files in one pass, and since the package count is saved first, updating it when some of the RPM files could not be processed is not trivial. I see three possible solutions:
a) add an extra stat() pass in "createrepo -i" case, and remove non-existing files from the list. Then we'll use the correct package count. However, this won't work 100% .. eg zero-sized *.rpm files fail too late.
b) re-compress all three *.xml files when some RPMs could not be processed, updating the "packages" attribute. It involves some re-parsing of the XML data, and is pretty ugly. However, (when it works) it covers all failure modes.
c) do some sanity checking on the file list first, then run as usual. When some files could not be processed, don't try to fix up the package count. exit with an error instead.
IMO viable solution is implementing either b or a+c. If all you want to handle is "file not found", then a+c is probably better (although I've implemented b already).
What about following:
* scan for all files (no stat) from package list (verify they're on disk)
* set packages=<package count>
* if a package fails to read
* report error
* don't write new repodata
* exit with non-0 exit code

Make sure the "packages" attribute is always correct.
The patch above checks all local files specified with -i option to be readable first. When some rpms fail after the "packages" count has been already written, it's a fatal error ($? == 1).
We can merge the upstream patch.

Make sure the "packages" attribute is always correct. BZ 1022001
We create XML files in one pass and the package count is stored
first. We need the count to be correct, so when a package is
being skipped, it must be a fatal error.
