#14833 — Old generated binary dependencies after renaming psycopg

[Multipart message — attachments visible in raw view] — view raw

Hello.
After fixing #1016031 "psycopg3: binary package name should be python3-
psycopg"
(I renamed package names, full changes:
* python3-psycopg3 -> python3-psycopg
* python3-psycopg3-pool -> python3-psycopg-pool
* python-psycopg3-doc -> python3-psycopg-doc)
I tried to rebuild reverse dependencies,
i.e. pgcli and python3-pgspecial.
Rebuild went without problems, new packages are the same
as old ones, but their binary packages still depend on python3-
psycopg3,
even though they build-depend on python3-psycopg.

I analysed build process and this dependency comes from
*.substvars file (e.g. pgcli/debian/pgcli.substvars)
which is generated by dh-python.
Apt search shows both python3-psycopg3 (in old version)
and python3-psycopg, so I suspect the former gets taken
in as binary dependency to be used.

What can I do to fix it? Should I ask ftp-masters to remove old
packages, or will the problem fix itself in the next few days?

Best regards.

Nope, pgcli does not build-depend on it, rather it explicitly
specifies Depends: python3-psycopg3.  Likewise, python-pgspecial
specifies the same Depends (though it also has a Build-Depends:
python3-psycopg3).  These packages will need their dependencies
updating.  (You might also consider making python3-psycopg Provides:
python3-psycopg3 and likewise for the other two binary packages for
bookworm.)

Best wishes,

   Julian

No, this is not the problem.
I checked (rebuilt packages with) different variants - with and
without python3-psycopg[3] as explicit dependency. In all the cases
dependency for python3-psycopg3 comes from ${python3:Depends}
via  pgcli/debian/pgcli.substvars which contains
python3:Depends=python3-cli-helpers, python3-click, python3-configobj,
python3-pendulum, python3-pgspecial, python3-prompt-toolkit, python3-
psycopg3, python3-pygments, python3-setproctitle, python3-sqlparse (>=
0.3), python3:any.

When python3-psycopg is in Depends in debian/control, it just gets
added - so binary package's Depends contains it twice (once
python3-psycopg3 from ${python3:Depends, once python3-psycopg
mentioned explicitly; in case of pgcli the second one is versioned).

Sample line from control file for pgcli, which contains both
python3-psycopg and python3-psycopg3:
Depends: python3-cli-helpers, python3-pendulum, python3-pgspecial (>=
2), python3-pkg-resources, python3-prompt-toolkit (>= 3.0), python3-
psycopg (>= 3.0.14), python3-sqlparse (>= 0.3), python3-tabulate,
python3-terminaltables, python3-click, python3-configobj, python3-
psycopg3, python3-pygments, python3-setproctitle, python3:any

I tried to analyze dh_python3, but could not understand where exactly
fills it in list of (additional) dependencies. They are generated
somewhere between dh_python3, dhpython/pydist.py,
and dhpython/depends.py (all files belong to package dh-python
and are in /usr/share/dh-python).

So - any tips how to fix it would be really helpful.

Best regards.

You'll need to add a py3dist-overrides file in /debian.  The details are in the dh-python or pybuild documentation.  I don't recall where.

Thanks for tip. Summary, for others with similar problems:
Solution is described in dh-python documentation
(man dh_python3, section dependencies).

Mapping of name psyscopg to python3-psycopg3 is in file
/usr/share/dh-python/dist/cpython3_fallback, provided
by dh-python. It's quite long file, containing many
of such translations.

I created debian/python3-psycopg.pydist which got installed
to /usr/share/python3/dist/python3-psycopg, and provided proper
mapping. I guess when mapping in dh-python is fixed, I'll be
able to drop *.pydist files.

Best regards, and thanks for help!
