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
Some modules (httplib, StringIO, ...) were renamed in python3. This
patch try to import the proper symbols from python3 and then fallback to
python2 in a case ImportError will appear.
There is one exception, python 2.7 got the io module with StringIO, but
it allow unicode arguments only. Therefor the old module is poked before
new one.
this patch
1.) removes the iteritems/itervalues, which were dropped in py3
items/values are used instead
2.) add an extra list() in a cases the list-based access is needed
(included appending, indexing and so)
3.) changes a sorting idiom in few places
instead of
foo = dict.keys()
foo.sort()
for i in foo:
there is a recommended
for i in sorted(dict.keys()):
4.) in one occassion it removes a if dict.has_key() by simpler
dict.get(key, default)
- util/rpmquery:
* added new methods "is_src", "is_nosrc" to check if the package is
a src rpm or nosrc rpm
* fixed "canonname": this never worked for src- or nosrc rpms
- minor code restructuring
Note:
in order to fetch the cpio archives osc uses "getbinarylist". The
drawback is that "getbinarylist" doesn't generate an ".errors" file
if we're requesting a non-existent filename.
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
* so far it was only used for querying rpms which can be done with the rpmquery module
- core.py:
* removed data_from_rpm() and tag_to_rpmpy() methods
- util/rpmquery.py:
* added staticmethod "query()"
- commandline.py, fetch.py:
* use rpmquery module instead of rpm-python/data_from_rpm()
* ascii SVR4 no CRC also called "new_ascii"
- no directory/PIPE/blk etc. support atm. Some of it might be implemented later in case I'm bored:)
- format implementation is based on src/copyin.c and src/util.c (see cpio sources)
- it is needed to investigate #477690 ("osc fetching binaries really slow")
