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]]

1. Checks a repo in the given or in the current directory;
2. Checksum verification is performed only if the flag -c is specified.
3. Update files, if the flag -u is given. Update url, if given, is written to the file .url in the dir to be checked. Or is read from this file if it is not given.
4. Show redundant files, if the flag -r is given and the repo is OK.
5. Remove redundant files, if the flag -rr is 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).
