[yast-devel] Fixed $Id$ expansion in SVN Trunk
by Ladislav Slezak 29 Apr '09

29 Apr '09

Hi all, I noticed that many files in yast have $Id$ tag in the header but it is not expanded to full string by SVN so the tags are useless. The problem is caused by empty svn:keywords property. I have fixed properties of all files in SVN Trunk which contained unexpanded $Id$ or $Id:$ string. If the expansion should not be used in a SVN file then remove the property or the tag. (Btw I used find . -name '*.ycp' -exec grep -l '\$Id:*\$' \{\} \; | xargs svn propset svn:keywords "Author Date Id … [View More]

[yast-devel] some ruby/rails code tips
by Duncan Mac-Vicar P. 27 Apr '09

27 Apr '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Some stuff I noticed in the code that I collected as tips :-) - - obj == nil -> obj.nil? - - str.length > 0 -> str.empty? - - if str && str.length > 0 This is tricky, not only because str.length should be tested with empty, but this test is so common in web forms, that rails adds the method Object#blank? so one can test nil? and empty? in one shot. -> str.blank? - - comments next to 'end', if we need to comment … [View More]next to an end to give a hint to which block it belongs, it means we have to refactor that code and split it/un-nest it. If you are commenting an end block, you need then to feel guilty. Your face has to go red and you make a concrete appointment to fix that code ;-) - - Something like: if not @user.home_directory.blank? command << "home=#{(a)user.home_directory}" end (already refactored to use blank?) can be refactored to: command << "home=#{(a)user.home_directory}" if not @user.home_directory.blank? This is not very important, but if you have 20 of those blocks in a row, the continuous starts and end of one line blocks make code too verbose and eyes have to indent and unindent all the time, while a one liner reads as english. - - Use and learn stdlib methods: if not @user.groups.blank? counter = 0 grp_string = "" @user.groups.each do |group| if counter == 0 grp_string = group[:id] else grp_string += ",#{group[:id]}" end counter += 1 end command << "grouplist=#{grp_string}" end What are we doing here? just converting an array into a string, but with commas. So first we are duplicating Array#join. I guess the code does that because it has a collection of Group objects, and it want to create an array of ids of those groups. You can get [1,2,3..] as the array of the group ids by using Array#map: groups.map { |group| group[:id] }. Add Array#join to the equation: groups.map { |group| group[:id] }.join(',') and you have all the code above in one line! :-) it returns "1,2,3" as a String. I fixed most of the issues mentioned, but sure there are more. Fix them as you spot them. cheers Duncan -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iEYEARECAAYFAkn0uTQACgkQzR62qWZ+QtEkLgCfVSPfrWXY88ZBG3Wrxj5b/Hnr pKEAoJTQPD9/+3DF27rQa1KVNoOxp6ke =erdq -----END PGP SIGNATURE----- -- To unsubscribe, e-mail: yast-devel+unsubscribe(a)opensuse.org For additional commands, e-mail: yast-devel+help(a)opensuse.org [View Less]

[yast-devel] Yast as a DBus service
by Ladislav Slezak 27 Apr '09

27 Apr '09

Hi all, I'd like to announce the Yast DBus service which is now available in SVN Trunk and in FACTORY. You just need to install yast2-core-2.18.7 package [*]. The new service can export every Yast name space, even non YCP modules like Users (Perl) or Pkg:: (C++). This service should be used as the base component for our new Yast Web interface.

[yast-devel] discussion points for restful api
by Duncan Mac-Vicar P. 27 Apr '09

27 Apr '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 * What to Discuss (we should meet and find solutions) - - Namespaces, domains This topic is still blur. We want to namespace resources, however it looks like REST convention only namespace resources if they are nested. So I have a small feeling that by following to much RESTful practices we are ignoring others. If we will have /system in the url, that has to be a resource too. In other parts we need to also figure good apis. Right now … [View More]stuff like patch install is broken, because the resources are automatically routed (map.resource), so stuff like "install" does not work. We have to think how are we going to handle those, at least sit down and define the few domains we will do for the start. Either we make it possible for plugged resources to handle custom actions (patches.put(:install)), making exceptions here and there, or we define more complicated ones. In this case I do think creating a packageinstallation resource is too-much. http://www.slideshare.net/calamitas/restful-best-practices (slide 28,29...) gives a good example. Rails allows to create custom methods, like /project/1/validate with PUT, which would "validate" a project. However those slides tell that one does not validate a project, but create a project-validation resource. We don't subscribe to a group but create a group subscription (therefore nested resources), one does not deactivate an account but delete an account activation. (Slide 44 is funny). For example, the current automatic resource registration does not allow nested resources. The current navigation of resources is cool, but on the client makes things complicated for nested resources. You need to know the urls, - - Permissions permissions is a nested resource of users, which is now a separate resource plugin, therefore I changed the users plugin to manually map permissions as nested. However the current permissions is highly dependent on resource names, and the whole discussion about namespaces, domains, etc makes this very inconsistent. We need to design this so we can enable it. - - packaging While the original Makefiles are there, they are mostly duplicates. For the users plugin, in addition to the Makefile, I have a Rakefile, which for example has a package task desc 'Generate tarball package' Rake::PackageTask.new('www', :noversion) do |p| p.need_tar_bz2 = true p.package_dir = 'package' p.package_files.include('**/*') p.package_files.exclude('package') end As this code will be duplicated in every plugin rakefile, we could create a kind of devtools with these tasks, because they are shared between plugins, web service and then a Rakefile would need only to require 'yast/tasks' or something. Also, question here, why the current spec file marks directories as %config? Ie: %config /srv/www/%{pkg_user}/vendor/plugins/%{plugin_name}/app ? - - Be more strict with conventions and naming. For example /etc/yast_user_roles is not very descriptive, specially when we already have a /etc/YaST (which we should use?: discussion). cheers Duncan -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iEYEARECAAYFAkn0uKMACgkQzR62qWZ+QtF+wQCfQ0CEMgBEJhraanNiA1Hp/PTA JQsAoL142mAcy7PpAg3NXew8qPJJjfHj =2ynS -----END PGP SIGNATURE----- -- To unsubscribe, e-mail: yast-devel+unsubscribe(a)opensuse.org For additional commands, e-mail: yast-devel+help(a)opensuse.org [View Less]

[yast-devel] preparing for demo, changes
by Duncan Mac-Vicar P. 26 Apr '09

26 Apr '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi! As we have to demo on Tuesday, and on Thursday it was pretty broken :-), I went over all the code to make it work again. I did some pretty important changes which I detail below, and I enumerate below some topics we need to discuss this week in a separate mail. Also at the end I enumerate some code related issues I found, in a separate mail. - - First, moved all *-plugin to plugins/* plugins don't have src/ directory anymore, they start at … [View More]the top-level (app, controller...) and the spec and dist files are in the package/ directory. Reasoning: 1.- all rails plugins are hosted that way. If some day we split a plugin, the plugin has to start in the directory where lib, app, etc are. That allows people to use script/plugin. It is a convention, changing it breaks any existing rails tools. 2.- originally, goal was to avoid symlinking and finding plugins automatically in the source code. We have to make running from the source tree easy if we want lazy people to help. 3.- Originally, I wrote my own Rails::Plugin::Locator which was able to find plugins with /src directory in the source tree. It worked pretty well, but Rails::Plugin defines Rails::Plugin#name as File.basename(@directory), which means, all plugins got the name :src. So Rails assume the directory is the name of the plugin. AI: update wiki page, installation, unless someone has good arguments for keeping src/ ;-) - - Changed how service routes are loaded. We don't go over vendor/plugins/* anymore, but over loaded plugins directory(). That allows for what is below. - - We automatically find plugins in the source tree RAILS_ROOT/../plugins by adding it to the plugin search path, so no need to symlink. Later we could also find plugins one level more up, so plugins checked out from a separate git repo are also found, and make development a breeze. - - Therefore ResourceRegistration has now register_plugin() method, and that one is used. We don't iterate vendor/plugins anymore but just go over found plugins and look there. - - I disabled the use of namespace and domain for now. Just because the client stopped working, and the discussion with Klaus about it was still in the middle. Note, everything is there, just the route_all method does not take them into account. - - what is still broken: * permissions, see discussion mail.

[yast-devel] New CWM modul for unified table manipulation
by Josef Reidinger 02 Apr '09

02 Apr '09

Hi, I add to CWM module CWMTable. This unify using table renderer of entries and its standard manipulation operations. At first Why you should start using it? Because now each yast module which uses table have different behavior and it is confusing to users. Also adding new features for all tables is not easy. E.g. I find confusing why in yast2-bootloader after double-click on cell it start edit dialog and in yast2-sudo it doesn't. Also handle up/down buttons is very incosistent (sometimes it … [View More]is auto disabled, sometimes not). So what features provide this little module? - optional add/delete buttons - optional edit button - optional up/down button - optional additional button - each button have separated handle function except up/down which have one - up/down is automatic enabled/disabled on first/last cell (this doesn't work as good as expect and need little debugging) - up/down handle functions gets also index and is ensured that is called only if possible move item up/down (this prevents bugs) - double click on cell call edit handler (if enabled) - wrapper for whole table enable/disable (with all buttons) - better readable code - same ncurses shortcut for Add,Edit,Delete F3-F5 disadvantage - can place only one unified table in dialog because it has hard-coded id TODO: - context menu also for additional button - allows another widget instead of additional widget - document it Example usage is attached. I welcome any comments.
