[opensuse-factory] Policy for src.rpm's?
Hi, I read on the wiki that you look for some solution how to avoid additional build time due to tar ball recompression. One way to do it is like in science:unstable/FreeCAD package. It builds directly in the git tree and is just packaging the _service file in src.rpm's. It would have a > 100MB tar.xz file otherwise inside. This us speeding up the build a lot. The disadvantage of that is that you can not do an offline build. And you can't get the code anymore, if the upstream scm server disappears _and_ build.opensuse.org is not working for you anymore. Therefore the distribution source tree alone would not be enough anymore for saitisfing the GPL. Either the upstream project or the OBS instance is required as well. Not sure if this is good enough for you, but I wanted to mention it at least. How does it look in practice? _service file has only the obs_scm and set_version service active. FreeCAD.spec is just packaging the _service file instead of the tar ball. %setup is skipping tar ball extraction via %setup -q -b %_sourcedir/%name-%version -T -D Have a look in the example here, you find this also switchable via build_tar_ball rpm macro: https://build.opensuse.org/package/show/science:unstable/FreeCAD (and yes, someone broke hdf5 stuff again, but does not matter here) bye adrian -- Adrian Schroeter email: adrian@suse.de SUSE Linux GmbH, GF: Felix Imendörffer, Jane Smithard, Graham Norton, HRB 21284 (AG Nürnberg) Maxfeldstraße 5 90409 Nürnberg Germany -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

No, v2 clearly states you need to provide binaries and sources the same way. Binaries on DVD => Sources must be available on DVD. A _service file won't do.

yes, we would need to put the obscpio files also on the source DVD then. And keep in mind that it is also okay just to put a written offer to send the source DVD on request. No one is really enforcing anyone to put the source in the src.rpm as only option. But "the way" in the context of the internet is less clear IIRC. It is for example 100% okay that mirrors do not mirror the sources as long as our main server is still providing it and they point to it. => So as long the upstream project is providing the sources and we point to it it should be okay as well. I agree that the enforcement to create an account for OBS would be a problem as long as the binaries are downloadable without. However, as said before, this could be solved. I just wanted to mention this approach here since the wiki asked for ideas how to avoid the re-compression times. This would be one way and I think the GPL issues could be solved as well... -- Adrian Schroeter email: adrian@suse.de SUSE Linux GmbH, GF: Felix Imendörffer, Jane Smithard, Graham Norton, HRB 21284 (AG Nürnberg) Maxfeldstraße 5 90409 Nürnberg Germany -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

at build time, the sources from some SCM are provided as an extracted tree already to the build. But if you want to put them into some source rpm, you need to turn this into a file again. So you would need to tar them. And usually untaring it again as this is what %setup does usually by default. This was intended as a response to the question how to avoid these steps (and recompression). -- Adrian Schroeter email: adrian@suse.de SUSE Linux GmbH, GF: Felix Imendörffer, Jane Smithard, Graham Norton, HRB 21284 (AG Nürnberg) Maxfeldstraße 5 90409 Nürnberg Germany -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

It would make sense for sure nowadays to make the build process smarter wrt dealing with distributed scms.

I don't read that in the GPL. They (a tarball, cpio archive, expanded git checkout, whatever) need to be on the same media set as the src.rpm, but I cannot see how a HOWTO telling "SRPMS/foo.src.rpm needs sourceballs/foo.zip for building" and both delivered on the same DVD / the same would violate the GPL.

There is a reason the sources are in /sources and - most mirrors don't even fetch them. As they are so seldomly downloaded, there is little interest to mirror it.

Actually, .src.rpm are often of limited usefulness on their own. Our build process relies on carefully prepared build environment, both w.r.t. what is installed and what is _not_. Some of are packages won't even build when you try rpmbuild on the .src.rpm.

I regularly use the .src RPM to build for targets that are not available on OBS. Quite often rpmbuild works out of the box. If not, I still have the complete source with patches and the spec file to make any needed modifications. I find them extremely useful!

I agree but that part could hopefully be done in a smarter way than obscpio.

Sure, if the content is already compressed. If it's an uncompressed directory tree like a git checkout, compressing that one way or another would still make sense. cu Ludwig -- (o_ Ludwig Nussel //\ V_/_ http://www.suse.com/ SUSE Linux GmbH, GF: Felix Imendörffer, Jane Smithard, Graham Norton, HRB 21284 (AG Nürnberg) -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

well, yes, but please note that this is a limitation of rpmbuild in first place. It requires files for the src.rpm's. OBS is happy to skip them... You could even go that far and say that we won't ship any src.rpm's at all anymore. Just the sources as they come out of a package checkout.

Well, you would need to enhance rpmbuild here. And you need to think about the special cases. We could of course also avoid rpmbuild changes and adapt the obs_scm service that it is parsing the spec file, downloading and rewriting the spec file. Not sure if that is a good idea though, since it brings complexity for special cases (eg. submodules yes/no), multiple spec files or other build descriptions. -- Adrian Schroeter email: adrian@suse.de SUSE Linux GmbH, GF: Felix Imendörffer, Jane Smithard, Graham Norton, HRB 21284 (AG Nürnberg) Maxfeldstraße 5 90409 Nürnberg Germany -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

That's it basically. All the rest should be automatic. Can we get to that somehow without extra config files?
Well, you would need to enhance rpmbuild here.

Have a look in the example here, you find this also switchable via build_tar_ball rpm macro:

Hi,
I read on the wiki that you look for some solution how to avoid additional build time due to tar ball recompression.
One way to do it is like in science:unstable/FreeCAD package. It builds directly in the git tree and is just packaging the _service file in src.rpm's. It would have a > 100MB tar.xz file otherwise inside.
This us speeding up the build a lot.
The disadvantage of that is that you can not do an offline build.
And you can't get the code anymore, if the upstream scm server disappears _and_ build.opensuse.org is not working for you anymore.
Therefore the distribution source tree alone would not be enough anymore for saitisfing the GPL. Either the upstream project or the OBS instance is required as well.
Not sure if this is good enough for you, but I wanted to mention it at least.
How does it look in practice?
_service file has only the obs_scm and set_version service active.
FreeCAD.spec is just packaging the _service file instead of the tar ball.
%setup is skipping tar ball extraction via %setup -q -b %_sourcedir/%name-%version -T -D

(and yes, someone broke hdf5 stuff again, but does not matter here)
bye adrian
My team is also interested in faster build on obs, in the coming weeks i'll be looking at finishing a patchset that will allow rpmbuild to do all the post build steps in parallel, ie building multiple sub rpm's at once given that most of our larger packages ship multiple rpm's this should also help speed up many builds, I can't remember if the src and debug rpm's will also be built in parallel. -- Simon Lees (Simotek) http://simotek.net Emergency Update Team keybase.io/simotek SUSE Linux Adelaide Australia, UTC+10:30 GPG Fingerprint: 5B87 DB9D 88DC F606 E489 CEC5 0922 C246 02F0 014B
