I see, but could you please elaborate a bit more why this is actually
needed? What goes wrong at the moment? Why do you need networking
inside the schroot environment?

Best regards,
Florian

I assume Isar considers networking via proxy in such as downloading 
something in do_fetch, resolving dependencies in do_dpkg_build and 
package installation on the target root filesystem in do_rootfs_install. 
We can actually use it in such typical cases with no problem.

This change has effect on a very limited case, where a self-built 
package fetching a source package via the apt:// scheme in SRC_URI is 
specified as a native package (<package>-native) to IMAGE_INSTALL or 
SDK_INSTALL. In this case, the source package is fetched via apt-get in 
schroot in do_fetch_common_source but proxy environment variables are 
not set in the executing shell function.

Isar would overlook this case compared to other fetching cases 
considering proxy and this change is to improve it.

Regards,
Kazunori

It seems that I missed that the apt:// fetcher is invoked quite late,
so already inside the schroot environment. That is done that way to use
the apt machinery of the target distribution already.

So yes, that seems correct.

Thanks for the additional information. You could (if you like) send a
v2 with that information part of the commit message. Will help the
maintainers as well.

Thanks for your contribution!

Best regards,
Florian

Thank you for instructing me on the existing apt fetcher issue. If 
possible, I would like to understand how to fix the issue properly. 
Could you please roughly clarify it on the code base, if you don't mind?

I found a different apt fetcher code from do_fetch_common_source in the 
following place and it seems to set proxy settings before fetching a apt 
source package inside the schroot environment.

https://github.com/ilbers/isar/blob/master/meta/lib/aptsrc_fetcher.py

The apt fetcher code seems duplicate, but do you think invoking this one 
at the appropriate moment is preferable?

Kazunori

[PATCH v2] dpkg-source: Export proxy settings

I would be grateful if this patch is accepted just with the additional 
message. I will send a v2 patch soon after this.

Please ignore the previous question if I mixed up something in it.

This one is the fetcher that gets involved when you have something like
apt:// in your SRC_URI.

The task that you modified (correctly) is invoked when building a
package. It fetches the Debian source package from the (internal)
repository.

There are two apt-get commands here. The first one is local only, the
second one will talk to "upstream" / the network as well. This will
obviously fail if proxies are involved.

I see. I mixed up the apt fetchers for SRC_URI and for being invoked 
when building a package. Thank you.

I have already posted a v2 patch with the commit message modified. I 
would be grateful if you could check it.
