Bug 155701

Created attachment 71518 [details]
log from zmd ("/usr/local/sbin/zmd -n")

(The three calls were for service list, catalog list and patches list.)

Looking at the logs, it fetches the XML from Friday.
Looking at armstrong:
-rw-r--r--  1 root root 747176 Mar  3 16:04 other.xml
-rw-r--r--  1 root root   1363 Mar  6 10:06 patch-aaa_base-1235.xml
-rw-r--r--  1 root root    281 Mar  3 16:05 patches.xml
-rw-r--r--  1 root root  16749 Mar  3 16:04 primary.xml
-rw-r--r--  1 root root   1222 Mar  3 16:05 repomd.xml


It is from Friday - this files are fixed by Klaus AFAICS. If they are correct I can't really say, but to my best knowledge Klaus has checked them with libzypp backend. 

Adding Tambet as we need also knowledge about ZMD.
Tambet, could help us on this.

Did you use latest zmd and libzypp packages from last night ?

If yes, please provide /var/log/zmd-messages.log and /var/log/zmd-backend.log

/usr/local/var/log/zmd-messages.log

zypp-zmd-backend is from STABLE

zmd from STABLE still reports "error : Attempt to serialize data containing null reference" - which was already fixed (bug #154715).

I'm using zmd from subversion (in /usr/local).

/var/log/zmd-backend.log gzipped

Looks like the patch file is wrong

Klaus or Jiri, could please check again? 
Or provide a mechanism to test myself?

Added Rudi to CC, as he is coding the engine creating these files.

If found in patch-aaa_base-1235.xml the following to lines and removed the latter, as I expect it an error:

        <plainrpm arch="i586" filename="aaa_base-10.0.42-57.i586.rpm" downloadsize="311342" md5sum="" buildtime="1141055104"/>
        <plainrpm arch="i586" filename="" downloadsize="" md5sum="" buildtime="1141055104"/>

I should be "patchrpm" I think, but in the generated file by autobuild, the patchrpm tag is also empty. It looks like it has been edited manuaelly, so it shouldn't be a problem of the engine, the engine just creates an empty patchrpm-tag.

Reassigning to Klaus for another validation run

Is the "md5sum" attribute mandatory or optional, could it be empty at all? I added the "external" md5sum of aaa_base-10.0.42-57.i586.rpm.

With current libzypp, armstrong.suse.de/download/Code/10/update/i386 looks just fine:

Found 7 resolvables
        5 packages
        0 selections
        0 patterns
        1 patches
        0 scripts
        0 messages
        1 atoms
        0 products

But I'm still not able to read them.

I've installed libzypp and libzypp-zmd-devel from stable and new zmd (zypp branch) from sources. Still no patches seen.

ad comment #7:
I use a ruby script using XML-RPC to test it; I don't know if there's other way, rug probably still doesn't support patches.

Tabmet, are you able to see the list of patches from this source, using zmd.packsys.get_patches call?

Created attachment 71699 [details]
zmd-backend.log

Yes.

>>> server.zmd.packsys.get_patches ("")
[{'status': 0, 'category': 'recommended', 'name': 'aaa_base', 'type': 3, 'installed': False, 'version': '1235-0', 'summary': '', 'arch': 'noarch', 'id': 844}]

Looks like I am doomed :-( 
This must mean I am using zmd a wrong way. Tambet, is it correct to use zmd from zmd-zypp branch?

test script

Could you please try to run this script?

I hope you need only 'ruby' package installed. It is necessary to set correct values of secret (line 105) and prefix, where deviceid file should be found (line 101).

The scripts only lists services, catalogs and patches. The call for adding the service is commented.

I tested with latest zmd from
https://svn.provo.novell.com/svn/nrm/avenger/branches/zypp/zmd

and libzypp-zmd-backend-0.0.8-36 and libzypp-0.0.8-36 packages.

I can't run the test:

tambet@164-99-120-83:~> ruby ./test.ruby
./test.ruby:3:in `require': no such file to load -- digest_auth (LoadError)
        from ./test.ruby:3
tambet@164-99-120-83:~>

Created attachment 71792 [details]
lib needed to run the script

sorry, forgot the library (just put it in the same dir)

tambet@164-99-120-83:~/foo> ruby ./test.ruby
./digest_auth.rb:25:in `gen_auth_header': private method `gsub' called for nil:NilClass (NoMethodError)
        from ./test.ruby:21:in `set_auth'
        from /usr/lib/ruby/1.8/xmlrpc/client.rb:320:in `initialize'
        from /usr/lib/ruby/1.8/xmlrpc/client.rb:357:in `new2'
        from ./test.ruby:115:in `initialize'
        from ./test.ruby:195

I don't feel that's the most productive usage of my time.

That's very nice from you.
I could say similar things about my attemps to get zmd and zypp working without the possibility to use properly built rpm package :-(

I'm sorry, but building packages is not my job. I'm sorry, but debugging your scripts that never even get to the point where service addition gets called is not my job.

This bug (as a bug of repo is fixed after comment #8); setting back to FIXED.

Now I'm finaly able to see the list of patches using XML-RPC (reinstalling machine, zmd from svn, libzypp from stable helped - I think the reason might have been in some old zmd cache). So this problem seems also solved.
