- Progress lines on stderr for each of the three graph resolutions (with package/missing counts and timing) so a slow remote no longer looks like a hang; -q suppresses them. stdout remains the clean report. - --verbose now streams Conan's output live via a tee instead of dumping it at the end. - Filter SyntaxWarning/DeprecationWarning before importing conans: Conan 1.x modules trip the stricter escape-sequence checks of recent Pythons and printed a screenful of noise on 3.14. - Drop the <3.12 requires-python ceiling. Conan 1.66 falls back to importlib where imp is missing; verified working on 3.14. Fix the Containerfile and docs that claimed otherwise.

"""conandeps - dependency, binary-availability and override report for Conan 1.x.
|
|
|
|
Given a conanfile.py this tool:
|
|
|
|
* lists the direct and indirect dependencies (host and build context),
|
|
* checks, for every dependency, whether a binary package exists on the
|
|
chosen remote for each build_type we care about (Release, Debug and
|
|
RelWithDebInfo by default) using the *exact* profile you would build with,
|
|
* reports every requirement override - explicit ``override=True`` ones as
|
|
well as implicit ones where a downstream consumer simply asks for a newer
|
|
version than a transitive dependency declared - as a hierarchy showing who
|
|
asked for what and which version won.
|
|
|
|
How it works
|
|
------------
|
|
Instead of hand-matching ``conan search`` output against the profile we ask
|
|
Conan itself: the dependency graph is built once per build_type through the
|
|
same ``conan info`` code path that ``conan install`` uses, and every node's
|
|
``binary`` status (Cache/Download/Update/Missing/...) is read back. This
|
|
honours ``package_id()`` customisations, options and the configured
|
|
``default_package_id_mode`` exactly the way a real install would.
|
|
|
|
Conan 1.x does not record overrides on the graph; the only trace is a warning
|
|
emitted by ``Requirements.update()``. We therefore capture Conan's output
|
|
stream while the graph is built and parse those lines.
|
|
|
|
Targets Conan 1.66. Uses only the standard library plus the Conan API.
