That's a bug in the bindings, we try to fix this ASAP.

Here libzypps strict typing gets into the way. zypp.KeyRing.ACCEPT_UNSIGNED_FILE refers to the DefaultAcceptBits enum and appears as Integer in Python.

However, zypp.KeyRing.setDefaultAccept() expects a 'DefaultAccept' type and swig cannot sufficiently decode zypp/KeyRing.h to provide an automatic type conversion.

A quick solution is to provide an explicit type conversion function, e.g. %inline %{ zypp::KeyRing::DefaultAccept toDefaultAccept(int bits) { return (zypp::KeyRing::DefaultAccept) static_castzypp::KeyRing::DefaultAccept(bits); } %} and use this in the sample code as zypp.KeyRing_setDefaultAccept(zypp.toDefaultAccept(zypp.KeyRing.ACCEPT_UNSIGNED_FILE | zypp.KeyRing.ACCEPT_VERIFICATION_FAILED) ) ^^^^^^^^^^^^^^^^^^^^ A more elaborate solution would involve SWIG typemaps (http://www.swig.org/Doc1.3/Typemaps.html) Klaus --- SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nürnberg) -- To unsubscribe, e-mail: zypp-devel+unsubscribe@opensuse.org For additional commands, e-mail: zypp-devel+help@opensuse.org

Thanks a lot, it does fix my issue.

Well, it looks like swig/python has some trouble to handle the DefaultAccept type at all (better said, I have trouble to tell swig how to handle it). It complains about possible memory leak and misssing dtor...

So I finally fixed it by providing integer based versions of KeyRing::defaultAcceptBits / KeyRing::setDefaultAcceptBits. You need zypp bindings version -0.5.5 for this. This version will be available soon at:

Try setting gpgcheck=0 in your test.repo file.

Thanks a lot, with TRUST_KEY_TEMPORARILY, it can build repo cache, but it can't give out any progress, how to set a callback for showing progress on building repo cache? Another issue is proxy, my network needs to set http proxy, how do I use libzypp bindings' python API to set proxy for every repo (some repos don't need proxy but others need)

Try setting

gpgcheck=0

The above will work too, but may not be what you want. Back to your code:

zypp.KeyRing.setDefaultAccept( zypp.KeyRing.ACCEPT_UNSIGNED_FILE | zypp.KeyRing.ACCEPT_VERIFICATION_FAILED )

If your repo is unsigned (no repomd.xml.asc / repomd.xml.key) ACCEPT_UNSIGNED_FILE will help.

But if your repo is signed the 1st question is whether to trust an unknown key or not. The 2nd question is how to handle a failed verification (ACCEPT_VERIFICATION_FAILED).

So you should also set one out of:

TRUST_KEY_TEMPORARILY (for this session only) TRUST_AND_IMPORT_KEY (permanently import to rpmdb)

I don't know whether this works with the bindings.

Swig primarily creates bindings 'into' C or C++ code. The reverse (like callbacks) is possible, but needs a bit of engineering.

That's what I wanted to say: I don't think this 'bit of engineering' happened.

Once python/callbacks.i contained some sketch(?) which was removed, as it referred to some obsolete report. Maybe this can be re-activated, but I currently don't have time to look at it...

Traceback (most recent call last): File "list_resolvables.py", line 99, in <module> for problem in Z.resolver().problems(): TypeError: 'SwigPyObject' object is not iterable , the below code also has issue: for item in installed_pkgs: if not zypp.isKindPattern(item): print item.repoInfo().packagesPath() print zypp.asKindPackage(item).location().filename() print "%s.%s %s:%d" % (item.name(), item.arch(), item.edition(), item.installSize()) swig/python detected a memory leak of type 'zypp::OnMediaLocation *', no destructor found. Traceback (most recent call last): File "list_resolvables.py", line 132, in <module> print zypp.asKindPackage(item).location().filename() AttributeError: 'SwigPyObject' object has no attribute 'filename' They are necessary for me, anyone can help fix them in next release, thanks.

Hi, I have two issues and hope you can be concerned about and fix it.

Hi,

sorry it took so long to catch up with this.

...

if I have a resolving issue, the below code can't work

if not Z.resolver().resolvePool(): for problem in Z.resolver().problems(): print "%s" % problem.description() raise "Solver Error"

The result is:

swig/python detected a memory leak of type 'ResolverProblemList *', no destructor found. Traceback (most recent call last): File "list_resolvables.py", line 99, in <module> for problem in Z.resolver().problems(): TypeError: 'SwigPyObject' object is not iterable

This is fixed now in 'master' branch of libzypp-bindings.

The fix for the other issue (AttributeError: 'SwigPyObject' object has no attribute 'filename') will come in a moment.

Both are caused by lack of 'knowledge' by swig about the internal data structures of libzypp. The short-time fix is to add more %include statements to swig (thereby increasing the overall size of the bindings), the long-term fix is to base the bindings on a new API concept (see branch 'new_api' in git).

, the below code also has issue:

for item in installed_pkgs: if not zypp.isKindPattern(item): print item.repoInfo().packagesPath() print zypp.asKindPackage(item).location().filename() print "%s.%s %s:%d" % (item.name(), item.arch(), item.edition(),

item.installSize())

...

swig/python detected a memory leak of type 'zypp::OnMediaLocation *', no

destructor found.

...

Traceback (most recent call last): File "list_resolvables.py", line 132, in <module> print zypp.asKindPackage(item).location().filename() AttributeError: 'SwigPyObject' object has no attribute 'filename'

This one is also fixed now in git master.

I want to build libzypp-bindings on openSUSE 11.1, 11,2 and 11.3, but obviously libzypp is old, so I also have to build libzypp even libsatsolvers, however I found many packages on openSUSE depend on libzypp so that I failed to install them, do you have any good solution for this?

libzypp-bindings is now able to detect the version of the underlying libzypp library. We could use that to adapt the bindings to the actual libzypp. I'll create a 'libzypp-bindings' project to just build the bindings for various OSses.

Is there a plan to add python/callbacks.i in next version?

We try.

Work has started in git master now ;-) Klaus --- SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nürnberg) -- To unsubscribe, e-mail: zypp-devel+unsubscribe@opensuse.org For additional commands, e-mail: zypp-devel+help@opensuse.org
