F11-0.88 unmerged patches summary
by Bernie Innocenti 03 Jul '10

03 Jul '10

Here's an executive summary of all outstanding patches in my queue: http://people.sugarlabs.org/bernie/sugar/sugar-0.88-patches/ Most of these have already been submitted to sugar-devel@ or attached to tickets in bugs.sugarlabs.org. Some of these patches have outstanding quality issues, but all of them have been integrated and tested for a while in F11-0.88 and together contribute to a better Sugar experience. == Bugfixes == sugar-toolkit/use-set_toolbar_box-in-example-code.patch sugar-toolkit/set-default-accelerators-for-Copy-and-Paste-buttons.patch These have been ack'd by Alsroot. Do we also need Erikos' approval? sugar-toolkit/sl1842-notify-red-alert.patch sugar/sl1842-journal-error-messates.patch The review has been swamped by a design discussion. It's not clear what Anish should do to pass review. sugar-toolkit/sl1948-Race-condition-with-name-widget-in-the-activ.patch This patch has a corner case in which it fails to update the activity name, but I think it's still a little better than the current behavior. See ticket for details. sugar/add-font-dpi-schema.patch This is a companion patch of a fix sugar-settings-manager which has already landed in git. It's needed by xulrunner (Browse). sugar/avoid-popping-an-empty-list-in-the-software-updater.patch Works, but James Cameron's posted a better counter-patch. Merge that one. sugar/click-on-journal-icons-with-a-exclusive-time-frame.patch Requested by the Waveplace folks. Please merge. sugar/dynamically-set-number-of-control-panel-columns.patch The approach to comoute the column width is wrong, but it produces better results than the current fixed number of columns. So, for now, I'm keeping it around. sugar/fix-duplication-of-OLPC-mesh-icons.patch sugar/fix-for-file-list-sorting-for-FAT32-formatted-flash-drives-in-journal.patch All the above have no issues to my knowledge and should be merged. sugar/use-the-spanish-verb-quitar-for-unmounting-devices.patch Better-than-nothing patch, but the real fix would require a gettext kludge in the code (see http://bugs.python.org/issue2504 ) == Minor bugfixes == sugar-toolkit/fix-two-trivial-shell-log-warnings.patch Reviewed on sugar-devel, should be merged. sugar-toolkit/sl1876.patch Patch is in comment 2 of the ticket. It has been overlooked becuase the ticket had also an attachment. sugar/fix-name-clash-set_state.patch Should be merged. == New Features == sugar/backup-0001-Volumes-Backup-and-Restore.patch sugar/backup-0002-Journal-XS-backup-and-restore.patch There are concerns about restore deleting new entries since the last backup. I agree, but since nobody seems to have the time to implement and test a more sophisticated procedure, at this time this is the best restore feature we have for Sugar. == Cleanups == sugar/simplify-the-definition-of-UpdateModel._bundles_to_check..patch Merge. sugar-toolkit/remove-incomplete-MANIFEST-support.patch The incomplete design and implementation of MANIFEST files has been laying around for 3 years. We can choose to clean it up now, or let it bitrot for another 3 years. == Experimental patches == sugar/set-default-scaling-to-100.patch This is only required on the XO. We should really autodetect this. sugar/cpu-and-memory-resource-indicator.patch Not yet reviewed on sugar-devel@. Not even tested by us yet. sugar-artwork/sl2006-icons-for-touchpad-panel.patch sugar/sl2006-touchpad-section-for-control-panel.patch sugar/sl2006-file-exists-check.patch Walter's XO-1 touchpad control panel. For me, it could already go in, but it would be nice to add a global shortcut such as alt-shift-t, and maybe move the functionality to a frame icon, for fast switching. sugar-toolkit/change-keep-string-to-keep-a-copy.patch Several alternatives have been suggested on the list, but nobody implemented them, so this one still stands. sugar-toolkit/kill-the-delayed-menus-for-good.patch This change has been at the center of a huge design / UX / testing flame war a while ago. I've merged it to observe user reactions, so hopefully we can have a polite discussion based on some real data. sugar/backup-0003-Journal-documents-volume-button.patch We no longer need this feature since we decided to disable Gnome, but other deployments may find it useful. (but journal crashes when you drop files on the icon) == Patches with outstanding issues == sugar-datastore/0001-Add-ctime-and-timestamp-properties-to-the-index.patch sugar-datastore/0002-Add-migration-from-DS-v0-code-for-the-new-properties.patch sugar-datastore/0003-increment-CURRENT_LAYOUT_VERSION-to-trigger-an-index-rebuild.patch sugar/sizelist-0000-cover-letter.patch sugar/sizelist-0001-Journal-Retrieve-filesize-from-the-datastore.patch sugar/sizelist-0002-Add-a-filesize-column-to-the-journal-list-model.patch sugar/sizelist-0003-Journaltoolbox-Add-add_separator-method-for-convenie.patch sugar/sizelist-0004-Add-a-ListViewButton-to-the-journal-search-toolbar.patch sugar/sizelist-0005-Rename-the-date-column-to-sort_column.patch sugar/sizelist-0006-Display-the-sorting-property-in-the-last-column.patch sugar/sizelist-0007-Expandedentry-Try-to-use-the-filesize-property.patch sugar/sizelist-0008-Implement-sorting-for-removable-devices.patch sugar/sizelist-0009-Add-sort-by-creation-time-option-to-the-ListViewButt.patch sugar/sizelist-0010-Add-ctime-property-to-the-journal-model.patch Andres' series for sorting the journal by size. There's an outstanding problem with ctime being an integer rather than a string, as expected by Etoys. Andres is working on a fix. sugar-toolkit/sugar-toolkit-dont-configure-fonts.patch sugar/sugar-enable-settings-manager.patch We had to temporarily exclude these because sugar-settings-manager does not yet work well on F11-0.88. == Obsolete patches == sugar/pe558-add-option-to-mount-any-user-directory-to-journal.patch sugar/pe558-backup-restore-front-end-for-control-panel.patch sugar/pe558-journal-management-control-panel-feature.patch sugar/pe558-modify-volumnestoolbar-to-mount-a-directory.patch This patch set has been replaced by Tincho's Journal-based backup/restore functionality. Keeping these patches around in case someone else prefers the control panel UI. -- // Bernie Innocenti - http://codewiz.org/ \X/ Sugar Labs - http://sugarlabs.org/

ANNOUNCE: F11 for XO-1 build 180py released
by Bernie Innocenti 19 Jun '10

19 Jun '10

This is a late announcement of the final release of the XO-1 images based on Fedora 11 and Sugar 0.84: http://people.sugarlabs.org/bernie/olpc/f11-xo1-py/os180py.img http://people.sugarlabs.org/bernie/olpc/f11-xo1-py/os180py.crc http://people.sugarlabs.org/bernie/olpc/f11-xo1-py/os180py.img.fs.zip This build is being deployed to 10 schools in Caacupé [1]. Feedback from teachers and teacher trainers has been very positive so far. == Changes relative to the previous release (os140py) == * GSM broadband support: add usb_modeswitch and usb_modeswitch-data, enabling more modem models to work with Fedora 11. (me) * Credit Sugar Labs in boot animation (me) * Add custom Browse home page with links to Paraguay Educa resources (rgs) * Update Turtle Art to pick Spanish translation (walter) * Re-enable olpc-update and the versioned fs (me) * Point software update control panel at http://wiki.paraguayeduca.org * Pull latest OS updates from upstream (fedora) == Bugs fixed == * Race condition with name widget in the activity toolbar http://bugs.sugarlabs.org/ticket/1948 * Some activities crashing when resuming from the Journal http://patchwork.sugarlabs.org/patch/15/ == Known bugs == * Unable to read FAT filesystems containing invalid file dates http://patchwork.sugarlabs.org/patch/43/ == How to help testing == Feedback from the entire community is very appreciated, although we're not planning any further releases of the Sugar 0.84 series. Bugs affecting upstream components are better filed in their respective trackers: * Sugar and activities: http://bugs.sugarlabs.org/ * Fedora 11: http://bugzilla.redhat.com/ * Drivers and OLPC customizations: http://dev.laptop.org/ * Paraguay-specific bugs: http://trac.paraguayeduca.org/ If you're unsure where a bug belongs to, use the Paragauy Educa tracker. Please, always assign these bugs to "Carlos", who will keep our status summary updated. == Using this build outside Paraguay == A few customizations make this image somewhat Paraguay-specific: * Limited language support: to save space, we've included only English and Spanish translations. * Image signed with the Paraguay deployment keys. Laptops from other regions need to be be unlocked in order to accept this image. * The software update control panel icon checks for new activities on our wiki rather than on laptop.org. * The Browse home page contains the Paraguay Educa logo and a few links to our website. We may find the time to release slightly modified images to meet the needs of other OLPC deployments interested in upgrading to Sugar 0.84. More importantly, we're happy to help other deployments produce their own OS images independently of us, thus exploiting Free Software's most important advantage [2]. == How to join development == This development cycle is closed as a new development cycle based on Sugar 0.88 has started already. Public builds will be available soon. Build system source: http://git.paraguayeduca.org/gitweb/users/bernie/olpc-os-builder.git Yum Repository containing our custom RPMs (along with sources): http://repo.paraguayeduca.org/f11-xo1-py/i386/os/ http://people.sugarlabs.org/bernie/olpc/pyeduca-repo/f11-xo1-py/ IRC: #olpc-paraguay irc.feenode.net (English spoken) [1] The actual production build is os179py. The only difference between os179py and os180py is improved compatibility with GSM modems.

F11-0.88 os260py
by Bernie Innocenti 18 Jun '10

18 Jun '10

This is the an interim release of Sugar 0.88 + GNOME series for XO-1. Please refer to this page for the current status and download instructions: http://wiki.sugarlabs.org/go/Deployment_Team/Sugar-0.88 With this build, all the major regression relative to 0.84 are fixed. The switch to Metacity resulted in a few hard issues on Fedora 11. There are still several smaller bugs to work on. All the new features planned for this cycle are now merged, with the notable exception of collections support for the activity updater, which urgently needs a volunteer. At this point, it seems too late for the much anticipated resurrection of Rainbow. Maybe next time. There may still be time to merge and stabilize a couple of minor features, such as a button in the Network control panel to re-register with the schoolserver. == Changes relative to the previous release (os258py) == * Integrate journal backup and restore to USB (esteban, tch) * Integrate function for mounting a GNOME Documents folder in the journal. Still presents some rough edges. (jasg) * Pull latest OS updates from upstream (fedora) == Bugs fixed in this release == * Make ALT-TAB work. It was caused by a bug with XUngrabKey() in the old Xorg server of Fedora 11, but we worked it around in Metacity. We spent a lot of time to figure it out! (tch, bernie) * Fix windows staying in frame after startup. It turned out to be a libwnck bug, solved by upgrading it to a more recent version (aa, bernie) * Fix fonts too big in all activities. This was a fallout of us temporarily disabling sugar-settings-manager, due to another bug (jasg). * CTRL-C/CTRL-V don't work in Turtle Blocks (walter) * Sugar sometimes restart. My fault: I included in the build an experimental Geode driver to check if it would now be safe to re-enable some EXA acceleration. It wasn't. (bernie). == Known bugs == We still have a bunch of less serious issues requiring attention: * Activity updater needs to support microformat and collections * Sometimes pulsing launch icon is delayed or absent (scheduling issue? Sometimes I can see Sugar eating up 50% of the CPU when starting an activity) * Font in Write is small and text does not fill the screen width. Sugar 0.82 and 0.84 used "Dejavu Sans", 0.88 uses "Times New Roman", which is smaller. (someone take it? pretty please?) * Disconnects from network on power save. This is a long-standing kernel bug. In 0.84, we "fixed" it by disabling power management. * Social Calc contains a race condition that makes it fail to start. Frankly, I would just ditch it, but teachers seem to like it very much * More GNOME lock-down. See the thread with subject "GNOME and protecting Sugar" on sugar-devel@. Thanks to anyone who could help us fixing these problems. -- // Bernie Innocenti - http://codewiz.org/ \X/ Sugar Labs - http://sugarlabs.org/

The Administration menu in GNOME
by Sridhar Dhanapalan 14 Jun '10

14 Jun '10

I've discovered that the Administration menu is hidden in GNOME on the XO-1.5 for the simple reason that there are no administration applications installed. It reveals itself once you install something that places an icon there. For example, you can install Fedora's GUI installer via the command line. First, connect to the Internet, then open a terminal. I normally just press Ctrl+Alt+Neighbourhood-View to get a console. Type this command: # yum install gnome-packagekit Answer Yes to all the questions, and it will download and install the relevant packages. After it has finished, reboot. If you aren't already in GNOME, switch to it. Click on the System menu at the top and you'll now see the Administration sub-menu. In that menu, click "Add/Remove Software". You may need to be patient while it is loading and waiting for system processes. If it is doing something, it will be reported in the bottom-left corner, just above the Help button. Once it's up and running, you can browse through the categories or use the search bar.

The sources for the current Fedora package. A source rpm has a tarball of the sources, and optionally a series of patch files relative to that "upstream" tarball. Not sure where to find those sources though, I'm not too familiar with Fedora procedures. - Bert -
