CheckRepo
Verification and update of local RPM repos. For those who have to update offline linux servers:)
Annotation
I maintain some offline linux servers and want to keep them up to date. For this reason I use rsync to get fresh repositories. Sometimes rsync gives bad results. Even if it seems that everithing is OK. So I need a tool to check an offline mirror of a repo.
Besides, some repos do not support rsync (mono-opt repos, for instance), only http. So I need a tool to sync them over http(s).
Here is such a tool.
Usage:
CheckRepo [dir] [-c] [-s] [-r[r]] [-u [url]]
- Checks a repo in the given or in the current directory;
- Checksum verification is performed only if the flag
-cis specified. - Update files, if the flag
-uis given. Update url, if given, is written to the file.urlin the dir to be checked. Or is read from this file if it is not given. - Show redundant files, if the flag
-ris given and the repo is OK. - Remove redundant files, if the flag
-rris given and the repo is OK.
The processing of redundant files is case-insensitive unless the flag -s is given.
The update process tries to download repomd.xml (always) and each file referenced
that is absent or having a wrong size or checksum (if the latter is supposed to verify). The downloading supports resume.
Workflow
Given a directory with an rpm repo, it assumes that there is a repodata/repomd.xml in that directory.
Then, it parses the repomd.xml for linked files (<data> elements) and checks for those files
existence, their size and checksum.
If it is all succeeded, it takes the data-file whose type attribute is primary,
unpacks this file if it is gzipped, extracts all the linked package elements and does almost the same
checks (existence, size, checksum + type == rpm).
After that, it outputs whenever the [updated] repository is consistent. If something goes wrong, the app outputs it.
To do
- Remove empty dirs in remove mode (
-r). - Show progress (files left to check; file check/download speed, estimate time).
