The packagequery.PackageQueryResult class is supposed to provide a
bytes API. Hence, packagequery.PackageQueryResult.evr() should return
bytes instead of a str. Also, adjust the single caller in the build
module.
The correct zst magic is b'(\xb5/\xfd' (4 bytes) (that's what obs-build
is also using).
Kudos to Tobias Ellinghaus for spotting this.
Fixes: #756 ("zst detection fails")
The following abstract methods are added to the PackageQueryResult
class: recommends(), suggests(), supplements(), and enhances().
Note that not all package/metadata formats have a notion of these
weak dependencies.
rpm rpmmd deb arch
recommends x x x
suggests x x x x
supplements x x
enhances x x x
(where "x" represents "supported"). In case of an unsupported weak
dependency, the implementation returns an empty list.
We need the weak dependency support in order to fix#363 ("osc build
-p ../rpms/tw doesnt send recommends to the server which makes client
side build behave differently to server side build").
The most visible change in python3 - removal of print statement and all
the crufty
print >> sys.stderr, foo,
The from __future__ import print_function makes it available in python
2.6
Any directory passed to --prefer-pkgs will be searched for a repodata
directory. If the directory does not contain a repodata directory, then
each ancestor directory is checked. This allows for the user error of
specifying an individual architecture directory (e.g. x86_64) instead of the
parent repository directory that contains the repodata:
repository/
x86_64/
*.rpm
repodata/
*.xml.gz
The use case for this feature is it allows snapshots of the OBS repositories
to be offloaded to an network-attached filesystem. repodata directories are
used as the xml.gz files are faster to read than the 100s of rpms in a given
snapshot. These snapshots are used to track older rpm sets that may be
deployed for testing.
- util/packagequery.py: added vercmp(pkgq) method
- util/debquery.py: currently vercmp(degq) is only a dummy method. The real implementation will follow soon.
* util/packagequery.py: it's used to query a RPM or DEB package. It also contains a
base class for all package types (PackageQuery())
* util/debquery.py: query a DEB package (name, version, release, provides, requires etc.)
- adapted util/rpmquery.py to use PackageQuery() as a base class
- minor changes in util/ar.py
