Feature changed by: jsuchome Feature #302955, revision 35 Title: Split translations out of installation system openSUSE-11.0: Candidate Priority Requester: Mandatory Projectmanager: Mandatory Requested by: coolo@novell.com Partner organization: openSUSE.org Description: The translations of yast are the biggest part of the installation image. These should not be part of the image, but should be pulled in from the product media as the user selects them. Discussion: #1: jsrain@novell.com (2007-11-09 13:18:17) Duncan, we will need a Linuxrc support for this. Can Steffen look into this feature? What comes to my mind is: Linuxrc needs to download and mount the language image for the language which user selected in bootloader menu (or English as fallback) Linuxrc needs to provide a support (eg. a script) which YaST can call when Language changes and downloads and "mounts" the new translation image It is questionable whether it should be YaST or Linuxrc who makes checks if the asked image is already downloaded, IMO it should be Linurc... #2: snwint@novell.com (2007-11-09 14:08:01) (reply to #1) I don't see linuxrc involved at all. YaST can just donwload he required files. Doesn't look that tricky to me. #3: jsuchome@novell.com (2007-11-09 14:29:36) (reply to #2) Maybe, but I do not know how. Lukas, don't we have some API in yast2- installation for that (copying target package from media to inst-sys, if I understand it correctly)? #4: snwint@novell.com (2007-11-09 14:32:40) (reply to #3) We've had exactly that discussion when we talked about loading the licenses. I think now is a good time to fix yast. I really don't see why other programs have to download various files for yast when yast could as well do it itself. And when this means doing the repo init earlier, then, well, do it earlier. #5: jsrain@novell.com (2007-11-09 15:02:22) (reply to #4) YaST can only fetch data from instlalation sources. Inst-sys can come from completly different location than installation sources do. YaST has no information where to get these images from. YaST would have to reimplement getting data from all kind of locations on its own (it cannot use libzypp, since at the location, there needn't be any valid source. That's why I'd like to reuse functionality which Linuxrc already has. #7: coolo@novell.com (2007-11-16 11:42:17) (reply to #5) Duncan, is it feasible to make the download functionality of libzypp seperate from valid sources. E.g. RepoManager::download(theurl_I_got_from_linuxrc, "/suse/translations/de.tar"); #10: dmacvicar@novell.com (2008-01-22 18:35:02) (reply to #7) Yes, MediaSetAccess or even MediaAccess can be used to get a file directly from an Url. The design is layered, MediaAccess sits on top of MediaManager(curl, iso, etc), MediaSetAccess on top, adding multiple media and media changing support, and RepoProvideFile on top, using the repos urls and trying different mirrors. There is also Fetcher which also sits on top of MediaSetAccess which provide queues and using already downloaded files. I think it is already used in YaST, YaST does transfer the content file from media independently from ZYpp. #6: locilka@novell.com (2007-11-09 16:54:01) (reply to #3) As already written by snwint, there is no way how to download anything from sources before they are initialized. So: no, there is no Installation API for that. As there can be an installation-(zypp)-source and a different inst-sys, Installation could either initialize the source as soon as possible but it still wouldn't know where to download inst-sys extensions. On the other hand, Linuxrc doesn't know which translations will be needed. So maybe inst-sys could provide some functionality (API) for downloading these extensions and merging them (downloaddir + adddir), YaST could then use that API. Just an idea... #8: michl@novell.com (2007-11-29 12:46:53) We should come down to tier1 languages here. #11: locilka@novell.com (2008-01-28 19:06:03) (reply to #9) According the forwarded mails, the Installation framework should call Get InstsysURL and RepoURL from /etc/install.inf (and combine them with a file/localization location to $url_to_download_file_from) /lbin/wget -v $url_to_download_file_from $path_to_save_file_to mkdir /mounts/localization mount -o loop $path_to_save_file_to /mounts/localization adddir /mounts/localization / Where (dir) and under which names will be the localization files (language images) stored? #12: locilka@novell.com (2008-01-29 10:39:24) (reply to #11) Snwint: does /lbin/wget check signatures of that file or does inst-sys provide some functionality I could use to check them? #14: snwint@novell.com (2008-01-29 11:06:11) (reply to #12) No it doesn't check them. But their SHA1sum will appear in /content. #13: snwint@novell.com (2008-01-29 11:03:05) (reply to #11) The language images are named root.XXX where XXX is XXX in yast2-trans- XXX. #15: locilka@novell.com (2008-02-04 07:25:10) (reply to #13) Stano's idea: For a better user experience, let's have all translations for the first dialog available from the very beggining (it's actually installation.mo ). In other words, installation textdomain should be still in the inst-sys-base, other text-domains in squashfs images. Download the language squashfs inst-sys extension after clicking on [Next] in the first dialog. That would make it visually faster. #16: locilka@novell.com (2008-02-04 07:58:54) (reply to #15) Ah, I've found that having installation.mo in the base inst-sys is currently the only way to avoid translation errors. YaST uses gettext for translating messages. The very first dialog using a gettext functions (e.g., initializing installation) is called even before the translation file is downloaded. In this case, gettext wouldn't find any translation. It would return untranslated message and also remember that there was no translation file available. After the installation adds the translation file, gettext would ignore it (This is known behavior since OES2 its Add-On integration into SLES10 SP1 workflow). #19: locilka@novell.com (2008-02-04 11:59:10) (reply to #16) Problem solved. According to snwint, the initial root.$LANG file is downloaded by Linuxrc, long time before YaST does anything. #17: locilka@novell.com (2008-02-04 08:06:35) (reply to #13) Where do we expect the root.$LANG files? On the installation repository or in the inst-sys? Consider this situation: RepoURL: nfs://install.suse.cz/11/?device=eth0 InstsysURL: nfs://miracle.suse.cz/11i/inst-sys/?device=eth0&aaa=bbb I assume that for de_DE URL nfs://miracle.suse.cz/11i/root.de_DE? device=eth0&aaa=bbb should be used but is that correct? Why not nfs: //install.suse.cz/11/boot/<arch>/root.de_DE?device=eth0 ? #18: snwint@novell.com (2008-02-04 14:22:41) (reply to #17) The files are taken from miracle because they should somehow match the other instsys files. #20: locilka@novell.com (2008-02-04 12:00:39) (reply to #13) Is there any possibility to list these (root.XX, root.xx_XX, ...) files? Because I haven't found any both systematic and valid solution. #21: snwint@novell.com (2008-02-04 18:07:19) (reply to #20) No idea; I'm using yast2-trans-allpacks when I build the instsys. #22: locilka@novell.com (2008-02-04 12:16:54) (reply to #21) This shows the list of $somehow supported translations ls -1 /usr/lib/YaST2/trans | sed 's/\.status//' however it is not ideal. #23: locilka@novell.com (2008-02-04 12:27:27) (reply to #22) A simple solution would be to introduce a new entry into the content file, e.g., SUPPLANGS . This variable would contain (space-separated) list of supported languages in YaST (all ${LANG}s for all root.$LANG files). Rudi, could you, please, add it? #24: snwint@novell.com (2008-02-05 10:07:12) (reply to #23) All root.xxx are already in content as they are sha1-summed. #25: locilka@novell.com (2008-02-05 04:34:37) (reply to #24) But their SHA1 is still not checked by the installation (YaST) when downloaded. It's in my TODO. #26: snwint@novell.com (2008-02-05 10:49:20) (reply to #25) Maybe. But it basically is the list you asked for in comment 23. Or not? #27: locilka@novell.com (2008-02-05 05:29:03) (reply to #26) It basically is the list I asked for for, but it doesn't contain the informative value that defines: hey! these languages are supported, use these files (...). For instance file, root.fonts , should be also signed and partly matches the pattern but fonts is not a language. And there might be several files later... So, I don't think this would work. #28: locilka@novell.com (2008-02-07 16:32:53) (reply to #25) I've found that SHA1 sum for checking the downloaded files cannot be computed :( Snwint: It seems that sha1sum is not part of the inst-sys. Linuxrc seems to check the SHA1 itself (sha1.c). What should I use? What would be the best solution? Integrate sha1sum into the inst-sys? #29: snwint@novell.com (2008-02-07 18:08:27) (reply to #28) Sure. I'll add it. #30: locilka@novell.com (2008-02-08 13:36:08) For jsuchome/country (possibly-buggy behavior reported by jsuchome): If user selects another language in the 'installation overview' (former 'proposal'), language selection needs to call this: if (Stage::initial()) { WFM::call ("integrate_translation_extension", [$["requested_language":language]]); } You should call it before Language::Set (language) is called. This is used only in inst-sys /Stage::initial()/, client integrate_translation_extension has been added to yast2-installation- 2.6.18 + #31: jsuchome@novell.com (2008-02-08 13:52:32) (reply to #30) + Actually, I would like to have this call (+all the checks when it is + necessary of course) inside Language::Set call, so that no code that + wants to change the language needs to care about this. -- SUSE Feature Tool: http://partnerfate.suse.de/?rm=feature_show&id=302955
