Hello Simon,

could you please describe in debian/README.source how the workflow is to
update the package python-datamodel-code-generator.

The visible branch layout shows it's uses some upstream branch to import
newer versions. But currently I've no clue how to import a newer version.

Regards
Carsten

I have been trying to get latest upstream packaged (help appreciated)
and have been experimenting with using upstream git directly to get all
files (pypi doesn't seem complete) with the following debian/watch:

Version: 5
Source: https://github.com/koxudaxi/datamodel-code-generator.git
Matching-Pattern: refs/tags/@ANY_VERSION@
Mode: git
Uversionmangle: auto

Some new build dependencies are needed, and I've managed to get
python3-hypothesis-jsonschema into Debian.  I've pushed packaging of
v0.66 here:

https://salsa.debian.org/jas/python-datamodel-code-generator/

But I have now also ran into the 'which' problem reported here:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1141004

E           TypeError: ExternalFile._load_value() missing 1 required positional argument: 'which'

Pipeline is here:

https://salsa.debian.org/jas/python-datamodel-code-generator/-/pipelines/1119388
https://salsa.debian.org/jas/python-datamodel-code-generator/-/jobs/9875950

Do you have any idea?  I fear it is some build dependency out of date,
but I'm new to Debian Python packaging so my debug skills are weak.  I
was hoping latest upstream would solve this, but alas no luck so far.

Control: retitle -1 python-datamodel-code-generator: Document upstream remote requirement in debian/README.source

The undocumented missing piece is that you need something like this
first:

   git remote add upstreamvcs https://github.com/koxudaxi/datamodel-code-generator

(Note that this is a deviation from the Debian Python team's policy:
https://salsa.debian.org/python-team/tools/python-modules/blob/master/policy.rst#git-procedures.)

The latest upstream release fixes this.  Simon, do you need help with
getting this packaged?  This bug is tied up with some pretty significant
dependency graphs (including the current pytest 9.1 mess).

Oh, that was unintentional and just my old habbit.  I don't understand
how my approach differs from that policy though, it doesn't seem
terribly clear exactly how package updates must work?  I'm happy to
adapt here.

Yes, please!  I've packaged a later upstream, but I got the same build
error, and there is some other issues too.  My python knowledge is too
weak here, could you start with

https://salsa.debian.org/jas/python-datamodel-code-generator

and see if you can get it to work?  Feel free to push to the main python
Salsa project as you wish, please don't wait for me before commits and
upload.

The practice in pretty much all our other packages is not to use
`upstream-vcs-tag` in `debian/gbp.conf`, so that `gbp import-orig`
commits the new tarball as a single commit.  I understand that there are
traceability issues, of course; the tradeoff is that it makes it easier
for team members to work on a large number of packages with minimal
setup.

(But I don't want to argue about it right now.  Other priorities!)

OK, will do.  I'm just about out of time for this working week, but I
should be able to start having a look at it on Sunday evening.

Good morning,

I don't mind much about which way for importing new upstream version is
the "correct" one. All the different possible approaches have ups and downs.

What I think is important is to give some information to other team
members how to import new stuff if it's not the de-facto default way as
Colin was describing. I did open this report as I simply wanted to
update that package (or at least look if a newer version is fixing the
test suite again).

We believe that the bug you reported is fixed in the latest version of
python-datamodel-code-generator, which is due to be installed in the Debian FTP archive.

A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 1140578@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.
