[yast-devel] redesign of webyast users module
by Martin Schmidkunz 12 Jan '10

12 Jan '10

Hi, please find some ideas for a redesign of webYaST`s "Users" module at: http://home.arcor.de/martin.schmidkunz/ (wasn`t sure if it is a good idea to store all the jquery stuff in my Export...) It is based on rlihm`s mock up (http://gagarin.suse.de/) The basic concept is to show only the most important table entry on a top level (e.g. user name). Therefore there are fewer elements on the screen which eases the use of the module and increases its self-descriptivness and its task orientation. On a second level which the user accesses after clicking on the user name the user can choose whether to "edit" or "delete" the entry. Again it is avoided to show non-task related information. Before deleting an item the user is prompted an "Are you sure?" pop up in order to increase error tolerance and prevent the user from unintended data loss. "Edit" shows the settings of the list entry. If more settings are available they are organized in tabs. The "Edit" dialog is left either via "Save" or "Cancel" New list entries can be added via "Add New Item" button on top the list. Concerning "basic concept" * "Save"/"Cancel"/"Add" do not work properly in the mock up * "Add" should be a wizard * User needs to click "Save" twice (once in the edit tab and then in the main window) I am not sure whether this is intuitive. What do you think about that? * list should be sortable but I am not caple of implementing this technically Concerning "Users" module * When adding a user currently there are 8-9 settings which needed to be adjusted and some of them seem quite obscure to me. So, what do you think: which settings should be really editable via GUI? Currently there are: Full Name Groups Default Group (GID) Home Directory Do not create home directory Login Shell Login Name UID Number Password Full Name, Login Name, Password and Groups seem quite clear to me but is it really necessary to set login shell and UID in the GUI? And home directory? Wouldn`t it make sense to have a sane default which could be edited via an editor? * What do you think about showing permissions in the users module as well? This would seem quite logical to me. What is the reason, why permissions and users are separated? Do you have any other topics concerning users module GUI? Looking forward to your comments!

[yast-devel] Printer
by Donn Washburn 12 Jan '10

12 Jan '10

Hey Group; This may be the wrong place to bring this up. However, it is a perceived Yast2 Printer problem. I have a Bother MFC-7840W USB laser printer that according to www.linuxprinter.org it works with Brothers drivers - I have them installed. lsusb and hwinfo --usb find it. And modprobe has all the modules required. But Yast2>Hardware>Printer under Add connection wizard USB will not show any devices or my USB printer. Why would this be the case. I went to USB and as I remember I hit enter and on the right side a new window shows up and is always empty. Yast2 then will not advance until something is selected -- 73 de Donn Washburn 307 Savoy Street Email:" n5xwb(a)comcast.net " Sugar Land, TX 77478 LL# 1.281.242.3256 Ham Callsign N5XWB HAMs : " n5xwb(a)arrl.net " VoIP via Gizmo: bmw_87kbike / via Skype: n5xwbg BMW MOA #: 4146 - Ambassador " http://counter.li.org " #279316 -- To unsubscribe, e-mail: yast-devel+unsubscribe(a)opensuse.org For additional commands, e-mail: yast-devel+help(a)opensuse.org

[yast-devel] Webyast: HttpMock and utility for it
by Josef Reidinger 04 Jan '10

04 Jan '10

Hi, in short: in branch for yast model I add also injector to HttpMock (standard library which is part of ActiveResource to test Rest-service based models) so if you plan write test look at it (or wait until it is merged). in long: Main goal to add models to webclient instead of dynamic one is easier testing of functionality which should go to model as controller is only thin layer which serves data. But I found that it is not so easy due to our design and also not so simple situation with rest-service site data. From my point of view correct testing of rest-service is provide same data as expected from rest-service and test if it work as expected. Now if test is ever present (not much models, I already fill bug) then it is huge mock which in real doesn't test much functionality. So we need some mock service which mock only target rest-service. Why I choose HttpMock? Even if our local consultant suggest use another framework I choose http because it looks like sufficient for our goal and it is already in ActiveResource so we don't need another gems. Why not use HttpMock without utilities? Of course it is possible, but you must simulate resource which translate interface to path and also permissions service which is out of test focus and test should not contain permissions service details. Also there is problem with authentication which must be solved on your own. So I create injector which add useful methods to HttpMock. How to use it in test: 1) define response (we separate at least visually tested data and tests): TEST_RESPONSE = <<EOF <test> <arg1>test</arg1> </test> EOF 2) now mock network service ( I suggest use it in setup - but of course for testing exceptions you should redefine it in method) def setup ActiveResource::HttpMock.set_authentification #a) ActiveResource::HttpMock.respond_to do |mock| header = ActiveResource::HttpMock.authentification_header #b) mock.resources :'org.opensuse.yast.modules.test' => "/test", :'org.opensuse.yast.modules.test2' => "/test2" #c) mock.permissions "org.opensuse.yast.modules.test", { :synchronize => true } #d) mock.get "/test.xml", header, TEST_RESPONSE, 200 mock.post "/test.xml", header, TEST_RESPONSE, 200 mock.get "/test2.xml", header, TEST2_RESPONSE, 200 mock.post "/test2.xml", header, TEST2_RESPONSE, 200 end end a) this utility sets authentification and target machine to predefined values b) authentification_header get hash which is passed to authenticate. It is required in mock header. otherwise it is not matched, but it is hash, so you can add your own values. c) define resources ( often it is just one, but for example if you use two rest-service (as time use time and ntp) then you define both. after hash argument you pass hash with options, which contains key singleton and policy ( mentioned in previous mail why I found it useless so it is optional, without it I use default which is no policy and single resource) d) mock permissions controller, just pass prefix and then hash with permission and if it is granted rest of method is common HttpMock which return expected values, so you can freely test it. 3) test model or controller :) def test_find_and_save test = TestModel.find :one assert_equal "test",test.arg1 #see XML for arg1 value assert test.save end Note: This utility class can be used without yast_model base model, because also dynamic created ActiveResource use this resources (but I do not test it, so expect problems) If you don't have any complains or suggestion how to improve it I plan to merge it together with yast_model. welcome any questions, suggestions or complains Josef -- Josef Reidinger YaST team maintainer of perl-Bootloader, YaST2-Repair, webyast (language,time,basesystem,ntp) -- To unsubscribe, e-mail: yast-devel+unsubscribe(a)opensuse.org For additional commands, e-mail: yast-devel+help(a)opensuse.org

[yast-devel] redesign of webyast users module
by stefan.eisenwiener＠freenet.de 30 Dec '09

30 Dec '09

Hi, I found an EMail by Martin Schmidkunz about this in my Mailbox. Which made me look at the concept of YaST at a hole. YaST today has three (frontend) servers (ncurses, qt, gtk), which should do the garphical visualization of the YaST Modules. Dose Modules should comuicate through SCR with the system level. Now WebYaST was added, but not as an (frontend) server to YaST, but as an outside wrapper witch calls the cli of some Modules (dose with have one), and brings own Modules these Modules. My question now is why did you through a way the original fronted concept of YaST?

[yast-devel] [ANNOUNCE] WebYaST now in gitorious.org/opensuse
by Duncan Mac-Vicar Prett 23 Dec '09

23 Dec '09

WebYaST is now available on http://gitorious.org/opensuse http://gitorious.org/opensuse/yast-rest-service http://gitorious.org/opensuse/yast-web-client http://gitorious.org/opensuse/ruby-polkit There is an initial opensuse-yast-developers team defined with access to those repositories. To switch your current checkout you only need to edit your .git/config origin remote If before it was git@git.opensuse.org:projects/yast/web-client.git Now it would be: git@gitorious.org:opensuse/yast-web-client.git To start, create your account at gitorious.org (you can use openID as well) and request to be added to opensuse-yast-developers group. (the best would be to have someone with admin permissions on each location). You have to configure your ssh public keys in your account settings then: http://gitorious.org/~yourlogin The repositories in git.opensuse.org are still accessible, but you can't push to them anymore. They will stay there until no repositories are left on that machine. gitorious provides feeds for each repository pushes, and per each branch commits with integrated commits reviews and merge requests. -- Duncan Mac-Vicar P. - Engineering Manager, YaST SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nuernberg) -- To unsubscribe, e-mail: yast-devel+unsubscribe(a)opensuse.org For additional commands, e-mail: yast-devel+help(a)opensuse.org

[yast-devel] Webyast: Models in webclient and some suggestion to rest-service resources
by Josef Reidinger 21 Dec '09

21 Dec '09

Hi, I just finish basic functionality of YastModel for webclient. I think that my solution is better then use_activeresource branch :) It is really intuitive to use. It is still only in branch waiting for your comments and improvements (branch jr-yastmodel). How use it? simply :) (example is time module in branch) create model: class Stime < ActiveResource::Base # 1) 2) extend YastModel::Base #3) model_interface :'org.opensuse.yast.modules.yapi.time' #4) end 1) Stime because Time already exist and we don't want to overwrite it 2) use ActiveResource not ActiveRecord (gives quite strange errors :) 3) contain definition of model_interface and needed fixtures 4) interface which you use now with load_proxy And model usage is then same as for common ActiveResource: @permissions = Stime.permissions #5) time = Stime.find :one #6) time.timezone etc... 5) It is class method because it is related to site, user and collection which is also stored in class, so I leave it in same scope 6) :one because time is single resource And there should be some discuss about format which provide resources. What is policy? Resource model in rest-service really lack any documentation Also I am not sure if we require singleton key, as type must know user at webclient and use find :all, :first:, :last etc for multi resource and :one for single resource. What I found inadequate is href, which should be separated to fixed prefix and changable collection name. Because now we have quite serius problems if we want use namespace for controllers. Feel free to post any question or suggestion to my solution. If martin agree with it I plan to merge it to master (as it is separate solution).

Hi, we now have 'WebYaST' as a standalone project in bugzilla.novell.com, open to the public. Being open was the reason for staying under 'openSUSE'. Now I intend to move all bugs over to 'WebYaST'. The move will happen either later today or tomorrow. We have full control over components in Bugzilla, please mail me for suggestions.
