Dear Maintainer,
Working on a debian derivative, I need to resolve my seeds with the
following setup:
Two mirrors:
- - a base mirror (eg. debian.org)
- - a partial mirror that contains my additional packages (eg.
derivative.org)
Two distros:
- - a distro from the base mirror (eg. 'stretch')
- - a distro from the partial mirror (eg. 'derivative')
A bunch of components: main, contrib, non-free, plus some additional
components from my partial mirror (eg. 'comp1', 'comp2').
So I throw it all to germinate with a command such as:
germinate -v \
-m http://deb.debian.org/debian \
-m http://deb.derivative.org/derivative \
-d stretch,derivative \
-c main,contrib,non-free,comp1,comp2 \
...
This makes germinate quite unhappy, with the following error:
Traceback (most recent call last):
File "/usr/bin/germinate", line 33, in <module>
main(sys.argv)
File "/usr/lib/python3/dist-packages/germinate/scripts/germinate_main.py",
line 155, in main
g.parse_archive(archive)
File "/usr/lib/python3/dist-packages/germinate/germinator.py", line 609, in
parse_archive
for indextype, section in archive.sections():
File "/usr/lib/python3/dist-packages/germinate/archive.py", line 237, in

"binary-" + self._arch + "/Packages")
File "/usr/lib/python3/dist-packages/germinate/archive.py", line 214, in
_open_tag_files
raise IOError("no %s files found" % tagfile_type)
OSError: no Packages files found
After looking at the code, I can see that germinate iterates on the
distributions (ie. 'stretch' and 'derivative' in this case), and for each
distro it iterates on the components, and for each components, it tries
every mirror. germinate considers it an error if nothing is found for a
given (distro,component) combination.
So what happens in the example here is that at some point, germinate will
hit the case where it looks for the 'comp1' component in the 'stretch'
distro, and it will fail. Because the 'comp1' component only exists in the
'derivative' distro.
Looking further at the code, I can see that this is only a self-imposed
restriction in germinate. I could easily disable this restriction, and
then germinate can actually keep going, and work as expected (well, as I
personally expect it to work ;)
Would you consider relaxing this restriction, and allowing this use-case
to work with germinate?
I actually pushed such a change on a git repo here:
<https://salsa.debian.org/arnaudr-guest/germinate/tree/arno>
The patch is simple, and just follows some logic that is already in
place for debian installers packages: my change just extend the
exception for source and binary packages, and drop a warning.
Please tell me what you think about it. Thanks!
Arnaud
