How to use tar_scm to just checkout github releases about obs-service-tar_scm HOT 6 OPEN

Hi @frispete ,

Because the features in #55 and #60 are not implemented yet. No news since then. 😢

However, you can still use some ugly hacks to adjust the package version. 😞 For example, use sed as this example. (Line 38)

Yours sincerely!

Hi @Firef0x,

thanks for your hints. That way, I've seen a way of successfully using @PARENT_TAG@.
If somebody could point me to an example, where the changelog is updated correctly, that
would be great.

Anyway, there's something, that still nags me, as I would like to limit the checkout on released versions, which would reduce versionformat to @PARENT_TAG@, but I fear (as in expect), that this is going to just paper over the fact, that the tarball is going to contain all changesets, regardless of the name.

This is further complicated by the fact, that I would like to create rpm spec files, the won't allow for the sed trick, you're using in PKGBUILD.

I really love the build service, but it escapes me, why the simplest things aren't solved or documented..

Thank you, this is really helpful.

Okay, here's the _service file, i'm experimenting with:

<services>
  <service name="tar_scm">
    <param name="scm">git</param>
    <param name="url">git://github.com/purplehuman/oinut</param>
    <param name="filename">oinut</param>
    <param name="versionformat">@PARENT_TAG@</param>
    <param name="revision">refs/tags/v1.2.3</param>
    <param name="changesgenerate">enable</param>
  </service>
  <service name="set_version">
    <param name="version">1.2.3</param>
  </service>
  <service name="recompress">
    <param name="file">*.tar</param>
    <param name="compression">xz</param>
  </service>
</services>

Although, I have to explicitly spell the version two times, it's is doing fine up to the point, where the local build wants to extract the tarball:

error: File /home/abuild/rpmbuild/SOURCES/oinut-1.2.3.tar.xz: No such file or directory

No wonder, since the service created these files:

_service:recompress:tar_scm:oinut-v1.2.3.tar.xz
_service:set_version:oinut.spec
_service:tar_scm:oinut.changes
_service:tar_scm:_servicedata

What's wrong?

Here's the important part of running the tar_scm service:

Run source service: /usr/lib/obs/service/tar_scm --scm git --url git://github.com/purplehuman/oinut --filename oinut --versionformat @PARENT_TAG@ --revision refs/tags/v1.2.3 --changesgenerate enable --outdir /tmp/tmpumLYdv

If you don't mind specifying the version twice in _service, you don't actually need @PARENT_TAG@ at all to do releases. Here's one I created yesterday:

• https://build.opensuse.org/package/view_file/home:aspiers/devilspie2/_service?expand=1

This line ensures that the tarball doesn't include all git metadata:

<param name="exclude">.git</param>

and this one automatically updates the .changes file:

<param name="changesgenerate">enable</param>

Please can you let me know if that solves your problem?

But I will gratefully accept a pull request which fixes #60, e.g. by implementing something along the lines of what I proposed.

@frispete Any update on whether the approach I demonstrated above works for you?

from obs-service-tar_scm.

Since 960d0ce one can use something like the following:

    <param name="versionrewrite-pattern">v(.*)</param>
    <param name="revision">refs/tags/v3.16.1</param>

This will strip the silly v and wala.
