0launch 0.36

Thomas Leonard — 2008-09-06T11:53:52

A new release of Zero Install (0.36) is now available: http://0install.net/injector.html Changes since 0.35: Note that although some changes have been made to better support Windows, this is untested. We are still looking for volunteers to test and debug it on Windows. - Update the display less frequently while downloading Debian bug #497569 says downloading uses 100% CPU (Simon Wenner). Not sure if this is the reason, but we're probably updating the display too frequently anyway. - Reject URIs without a path component (e.g. http://host). - Don't assume an RPM-based distribution just because /var/lib/rpm exists. Actually check for the /var/lib/rpm/Packages file instead (reported by Demetrio Girardi). - Reject obvious attempts to drag archives to 0desktop. People keep trying to drag .exe, .tar.bz2, etc archives to 0desktop. Reject URLs ending in these strings with a more helpful error message (rather than downloading them and complaining that it's not XML). - Record architecture for Debian packages We used to assume that a native Debian package had an arch type of '*' (i.e. it would always be compatible with everything). However, on a mixed 32 and 64 bit platform, we can't use a 64-bit native library with a 32-bit Zero Install package. Therefore, take notice of the deb's architecture too. Might need a similar change for RPMs too. - Use subprocess to unpack archives. Avoid fork() so it can work on Windows. - Don't use fork() for downloads; Windows doesn't support it. Uses subprocess instead. - Cache viewer's Close button now works. - Added Frank Richter's key.

Yes. I won't use the other (first) "feed key" any more (well, I can't - I forgot the passphrase. Shame on me, I know). I'll sign it with my "personal" key. -f.r. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/

CPU load when downloading

Thomas Leonard — 2008-09-04T18:52:10

Is anyone experiencing high CPU load when downloading things, as in this bug report? http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=497569 I've made a couple of changes to try and make it faster: http://repo.or.cz/w/zeroinstall.git (please check that it still works!)

2008/9/4 Demetrio Girardi niksula.hut.fi>: /var/lib/rpm exists (so it thinks this is an RPM-based distribution), but /var/lib/rpm/Packages doesn't, which produces the warning.

Hello, 0lauching the lyx feed fails, giving a warning about a missing /var/lib/rpm/Packages file, and saying that there are no implementations for the feed. Is this a problem of the feed, or of RPM? the latter is installed on this (freebsd) machine but I don't know how it is configured and I don't have root access. Attached is the verbose output.

Proposal for a "never seen" system based on Zero Install with Web 2.0 approach

Antonio Orlando — 2008-09-01T17:06:12

I want to propose here a system I've envisioned, where Zero Install would be perfect as a core. As system I mean something that could be an application normally loadable in the preferred platform (Linux, Windows, Mac, etc.), integrated with a web service, but for simplicity let's think at it like a Linux distro, and for more simplicity let's think at it as a live one. So, I load this live distro, and it asks for some user/password to connect to the companion web service, or offers the possibility to "register". The companion web service is essentially a database storing some infos: urls of apps, names, descriptions, stars, hearts, etc. Let's say I already have my account, so I type my credentials and here we go: my custom "desktop" is built on the fly with informations retrieved from the web service. Let's say I've not marked any app as "visible on desktop", so my desktop will be like this: Just a text-input field in the bottom bar, with two buttons: "Search", "Run the first one" and "Run my favourite" followed by a number, default #1. Let me name this text-input field with those buttons as "the Door"; it's the main user interface in our distro. Ok, I want to browse the web. Let me type "web browser" in the Door, and press the "Run my favourite" button. It's downloading something, then Opera jumps out. Now I want to find some bugs in a html page: I type "web browser" in the Door, change to #2 and press "Run my favourite", so it downloads and run Firefox. I could have typed "firefox" and pressed "Run the first one", it would have been the same. I could also have typed "browse the web", or "tool for browsing web", etc. Then I install the firebug extension, and check for those bugs. Enough PC today, I close Opera and Firefox. I'd like to allow my little sister to make a drawing on the PC, but I prefer into the RAM not onto the monitor like she's trying to do with my acrylic pen - doh! So I type "paint for kids" into the Door and press the "Search" button. The system answers with a table listing some apps, the OS they work on, the "stars" they have received from users, the "hearts" (i.e. how many users have setted it as a "favourite" app), the names, descriptions, link to comments, ... The results listed, and their order, are relative to how well my query matches the descriptions, or other "Door queries" - this will be more clear later - stars, and hearts. I can also order them by stars if I want, or by name, it's just a matter of clicking the table headings, as well as filtering results, etc. But I don't want to lose too much time now, I just want my sister to draw on my PC with a mouse. I have a look at the description of the first result, it has lots of stars, and it seems to accomplish exactly what I need: it's named "Tux paint", I've never heard of it, so I press the "Run" button in the first row of the table, and my sister is ready to go. When she has enough of it, I close it, and the system says: "You've never used this software (Tux paint), you can: give it a star, mark it as favourite, mark it as unwanted, put it on your desktop, associate other Door queries (DQ), ..." I'll give it a star, and I'll associate other Door queries just to be sure I or other users will easily find it: LANG.: english, DQ: "drawing for children" LANG.: english, DQ: "paint for children" LANG.: italian, DQ: "disegno per bambini" LANG.: italian, DQ: "programma per disegnare adatto ai bambini" All this stuff, of course, will be stored in the remote companion database. Do you begin understanding my idea? Probably not, because I've just sketched it a bit. Let's abandon our live distro, and setup that thing on our PC. So, this is my PC, with this distro installed. Let's say I've happily used it for about five years, and lot of important stuff and not so important is on this PC. My private stuff, work, apps with special settings, extensions, plugins, scripts made by me, documents, etc. A lot of stuff, a big bunch of stuff. This is my beloved PC, and I turn it on every day. Today, I want to do something I've never done before: I want to rebolve a strick (of course this does not mean anything, consider it a placeholder for whatever action ;) So, do you know what software I can use to rebolve a strick? What, you knew one but can't remember its name? No problem for me: It's just a matter of typing something like "rebolve strick" in the Door, and here it is an interesting list. Just a quick glance at the descriptions, and a click on the preferred "Run" button makes me ready to rebolve stricks as much as I need. Oh what a ugly interface, let me try another one... Yes, this is a pleasure, I feel this is very simple to understand. So I close the other one, and the system asks for feedback: I skip it, nothing to say about; maybe it was good in rebolving stricks, but the interface was a punch in my eye. I pass some time rebolving stricks with this new software, and after some practice I feel very comfortable with it. I close the app, and when the system asks for feedback I give it a star and mark it as favourite. So whenever I'll need to rebolve stricks, the system will know what I want when I press the "Run my favourite" button. As we're not relying on a live-CD anymore, the system asks if I want to cache it locally. I answer yes. Next time, when I'll search for "rebolve strick" in the Door, the list will have this on top, so the "Run" button on that row will directly load the cached copy (no download step). Can you better see my idea now? It's still sketched, but I think It's more clear now. Take a breath, let's go on. The system must communicate with a local and a remote database, and integrate those informations. The user interface in the OS has to provide to the user the means to smoothly interact with those databases. But it's not necessary that a app is stored somewhere in the internet for me to be able to use it: maybe I've written a software, and I don't want to put it on some server, it's just for me and I want it to stay only on my local machine. So, the system allows me to specify some Door queries associated to my software, eventually a name and a description, and I'll be able to easily run it whenever I want, the same way I run everything else. We've spoken in terms of running "apps", software, etc. This was a simplification I can try to remove now, as my idea does not focus on apps, but on sessions. That is to say, if one day I make a script to automagically fix corrupted rebolved stricks, which needs some actions, some apps with some settings, and I write instructions in a text file, etc.: the system allows me to "save" all that stuff - a session with some apps open, etc. - associating it with the Door queries that apply. So, searching for "fix rebolved stricks", I'll obtain in the first results (local) my solution. Maybe I've gone into the trouble of making that solution because the Door query "fix rebolved stricks" and similars does not provide any result. Three years later, I need to fix a rebolved strick. I search for "fix rebolved strick", and the system suggests there are two results with a similar DQ: "fix rebolved stricks". The first is my session I saved three years ago, stored locally, while the second is something new to me. I could try the new solution, but I'm pretty satisfied with my one so I click the "Run" button in the first row. By the way, nice to see there's a tool to fix rebolved stricks now, I'll try it next time. Just to be clear, other users searching for "fix rebolved stricks" won't see my script in their results, because it's stored in my local database. They will see only the results coming from the remote database, from their local database, and eventually from local database shared on a LAN. Everything in the remote database is addressed with http:// urls, while everything in the local database is addressed with file:// urls, or something like that. Time to change PC now. In order to backup/restore everything (and I mean everything, i.e. data, apps, settings for apps, etc.) I just need to copy/paste stuff from the old machine to the new one, or add the old hard disk to the new PC. When I'll use the new PC for the first time with this OS, it will say "the local database is empty, would you like to import one?", and I'll answer "yes, here it is the device where you should find it". And after a couple of seconds I will have everything like it was on the old PC. Let me see, I'm loading Firefox: oh yes, every extension working, here they are all of my bookmarks... I'm loading Opera now: nice, everything's there, my buttons, my userjs, all my mails, feeds, the widgets, even those uncompleted torrents are resuming... In my vision, the system should be OS-independent: I'm running a Windows system, I query for "rebolve strick" in the Door of my OS (e.g. a Python app), and the server answers putting on top of the list the matching results associated with Windows; maybe there are no results for Windows, but I'll see that I could rebolve stricks with Linux. I query for "sloope unwanted canugs" and I can see there is only one result and it is for Amiga, etc. On Windows, rather than using Zero Install, the system will track portable apps. If Zero Install will be ported on Windows too, good bye portable apps and welcome Zero Install. I've omitted a lot of stuff in my mind, but I hope I've succeeded in making a rough picture. It has to be the simplest system (from the user's point of view) you can imagine. With Zero Install and the Web, all this stuff is not so utopic. What do you think? (Thanks for reading!)

Using the architecture field from nativepackages

Thomas Leonard — 2008-08-23T11:55:21

We used to assume that a native package had an arch type of '*' (i.e. it would always be compatible with everything). However, on a mixed 32 and 64 bit platform, we can't use a 64-bit native library with a downloaded 32-bit implementation. I've changed the code to record the type for x86_64 packages so that they won't be selected in combination with 32-bit implementations: http://repo.or.cz/w/zeroinstall.git?a=commit;h=a1980f1fd207d171d480049a1890ffdb0f72ed02 We might need a similar change for RPMs too. Patches welcome...

Downloads page and Windows

Thomas Leonard — 2008-08-20T18:36:24

The downloads page was getting a bit long and complicated. I've split it into different pages for each platform: http://0install.net/injector.html This gives us some space to put in more detailed instructions, although currently it's just what was on the main page. Contributions welcome! I have, however, tested it on a Windows machine and thus greatly extended the Windows installation instructions. Still doesn't work, but if you'd like to help out here are some hints: http://0install.net/install-windows.html There seem to be some odd problems with file descriptors, backslashes, and DOS line-endings. The usual suspects. Help welcome!

Re: Distribution integration / OpenGLdependency

Thomas Leonard — 2008-08-19T21:03:16

2008/8/19 Frank Richter gmail.com>: Agreed. There are lots of ways to speed up a 3D app (turn off transparency, use lower-quality texture mapping, turn off textures, reduce clipping depth, use models with fewer polygons, use a smaller screen area, etc). Though it might be worth splitting up the level data into smaller chunks that can be downloaded as needed.

Re: FIle associations, icons...

Thomas Leonard — 2008-08-19T21:00:06

2008/8/19 Frank Richter gmail.com>: [...] How about: 1. Associate *.celzip -> application/x-zip-celstart 2. Associate *.gnucash -> application/x-zip-celstart 3. Get user to map application/x-zip-celstart -> celstart-launcher 4. Wait for user to open their accounts file 5. Profit! (this assumes the user was running celstart with limited privs... probably only to the data file they clicked on) The real solution to the MIME problem is to store the MIME type with the file (in the user.mime_type extended attribute). Then you don't need a mapping from name/content to type. But not many programs use this yet. Although sometimes there's an obvious program for a particular type, in general the MIME guessing rules are independent of any particular program. In any case, the MIME mappings file would normally go inside the package, I think. Other installers would expect it to be there. So it would be better to store the relative path to the file, rather than put the contents in the feed. Thanks!

Re: FIle associations, icons...

Frank Richter — 2008-08-19T19:36:07

Done. I guess you could argue for and against that - I'll leave that for KDE and GNOME people, respectively ;) Tho in general, I'd think registering a type may not necessarily be dangerous - you could perhaps maliciously mask the type of a file via a mime mapping - but any automatic association between a file type and a program might. However, I don't know what kind of possibilities exist for that (and how it could be prevented). I'll have to check it out, thanks for the pointer. -f.r. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/_______________________________________________ Zero-install-devel mailing list Zero-install-devel< at >lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/zero-install-devel

Silently adding stuff to the MIME mappings seems dangerous, though. There would need to be some kind of checkbox in the GUI ("Allow this program to update the MIME database" or something). If possible, you should try to get it in the freedesktop.org main database as well, though. As long as your type doesn't conflict with anything (e.g. "*.doc") they'll probably accept it. Thanks!

Re: Distribution integration / OpenGLdependency

Frank Richter — 2008-08-19T00:12:52

Well, I didn't see any way to hook custom commands in anywhere ... I guess one way would be to create a "wrapper feed": a really simple program that poses as the application you want. When launched, it does a system check or whatever and continues to launch the real app (e.g. by calling 0launch again) when the requirements are met. (Personally, I would find it a bit harsh to reject launching when the requirements are not met; rather, I would inform the user that given the current system the app may not run that well but leave it a possibility to continue.)

Distribution integration / OpenGL dependency

Thomas Formella — 2008-08-18T04:47:14

0launch 0.35

Thomas Leonard — 2008-08-16T14:59:52

A new release of Zero Install (0.35) is now available: http://0install.net/injector.html Changes since 0.34: New features: - Added support for multi-arch We can choose either x86_64 binaries or i[3456]86 binaries, but we can't mix both in a single process. Also fixed the sense of the OS and CPU tests so that we now pick the best OS and CPU match rather than the worst (oops!). - Added --cpu and --os arguments to 0launch This allows you to choose a binary for a different host. It's also useful on an x86_64 machine to run an x86 binary. Bug-fixes: - Don't create .desktop filenames with spaces; xdg-desktop-menu gets confused and gives a misleading error message ("does not have a proper vendor prefix") if the name contains a space. Reported by Thomas Formella. - Allow file:///path feed URIs. This is equivalent to just using /path. Useful for drag-and-drop from Konqueror. Reported by Matt Lawrence. - Log a useful warning if a user_overrides file gets corrupted. Don't know what could cause this, though. Reported on the ROX web-site. - Cope with os.uname not existing. Some systems don't support it yet. - Use subprocess instead of fork when running gpg. Some systems don't yet have support for fork(). Note that the download and unpacking code still uses fork, however. See "0launch doesn't work on Windows": http://sourceforge.net/tracker/index.php?func=detail&aid=2029407&group_id=76468&atid=547194 - Only try to download each icon once Before, we would keep trying to download an icon that was missing. Documentation: - Improved web-site design. - Improved epydoc. GUI: - Added "Show Cache" button to "0desktop --manage" window. - Added "0store manage" command to show the GTK cache viewer. The "Show Cache" button has been removed from the "0launch --gui" dialog box, since it didn't really belong there. Python API: - Removed a load of unused imports. Thanks, pyflakes! Also found a bug. Note that this is a slight API change, since it was previously possible to get these symbols from the wrong module without an error. - Moved CacheExplorer to zeroinstall.gtkui. - CacheExplorer now takes the iface_cache as an input - Moved help_box to zeroinstall.gtkui. - Moved some useful GUI code into zeroinstall.gtkui.gtkutils. - Added support to model. However, it still isn't supported yet (see the plash-overlay branch for one option, though).
