Package: python3-apt Version: 3.0.0 Severity: normal Hi,
While writing python scripts with apt_pkg, I discovered (by chance) that the apt_pkg.MetaIndex provides a 'type' property. It is important because the triplet (type, uri, dist) uniquely identify the MetaIndex (and the triplet is the only way I found to link the apt_pkg.MetaIndex to the aptsources.sourceslist.SourcesList sub objects) https://apt-team.pages.debian.net/python-apt/library/apt_pkg.html#apt_pkg.MetaIndex does not talk about the 'type' property. It is not present in /usr/lib/python3/dist-packages/apt_pkg-stubs/__init__.pyi: [...] class MetaIndex: dist: str index_files: List[IndexFile] is_trusted: bool uri: str class SourceList: [...] However, the property exists as shown by the following program: $ cat /tmp/test.py import apt_pkg apt_pkg.init() sources = apt_pkg.SourceList() sources.read_main_list() for source in sources.list: print(f'MetaIndex {source.type} {source.uri} {source.dist}') The property always returns "deb" (I got no "deb-src" even if I have some in my sources.list.d/* files). And type checkers complain about this property: $ mypy /tmp/test.py /tmp/test.py:8: error: "MetaIndex" has no attribute "type" [attr-defined] Found 1 error in 1 file (checked 1 source file) $ pyright /tmp/test.py /tmp/test.py /tmp/test.py:8:31 - error: Cannot access attribute "type" for class "MetaIndex" Attribute "type" is unknown (reportAttributeAccessIssue) 1 error, 0 warnings, 0 informations As the property exists, it should probably be added to the documentation and python hint type file (but as it always has "deb", I'm not so sure it is really useful in fact) Working on deb sources, I just saw while writing this bug report that apt_pkg.IndexFile are linked to the same apt_pkg.MetaIndex object independently of its type (and the MetaIndex always reports "deb" as said before). The kind of IndexFile seems discoverable with the label property. The documentation should list acceptable values ('Debian Package Index', 'Debian Source Index' and 'Debian Translation Index' it seems) If we want to link back apt_pkg.IndexFile to aptsources.sourceslist.SourcesList().exploded_list() it will be more difficult if we want to handle "deb-src" type. Note that even the triplet (type, uri, dist) [for type="deb"] needs workaround as uri can be rewritten in apt_pkg.MetaIndex (a final '/' can be added) Regards Vincent -- System Information: Debian Release: forky/sid APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'oldstable-updates'), (500, 'oldstable-security'), (500, 'unstable'), (500, 'testing'), (500, 'stable'), (500, 'oldstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386, armel Kernel: Linux 6.12.41+deb13-amd64 (SMP w/4 CPU threads; PREEMPT) Kernel taint flags: TAINT_OOT_MODULE Locale: LANG=fr_FR.utf8, LC_CTYPE=fr_FR.utf8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) Versions of packages python3-apt depends on: ii distro-info-data 0.66 ii libapt-pkg7.0 3.1.4 ii libc6 2.41-12 ii libgcc-s1 15.2.0-1 ii libstdc++6 15.2.0-1 ii python-apt-common 3.0.0 ii python3 3.13.5-1 Versions of packages python3-apt recommends: ii iso-codes 4.18.0-1 ii lsb-release 12.1-1 Versions of packages python3-apt suggests: ii apt 3.1.4 pn python-apt-doc <none> -- no debconf information
