This page goes hand-in-hand with the [[Feature requests]] page, as follows:
This page intends to layout a long term strategy for prioritizing software development on the XO. Feature lists for individual releases will appear on their respective pages as listed features get prioritized, scoped and a targeted. In addition to outlining goals and strategies, an extensive feature roadmap is maintained on this page. This page goes hand-in-hand with the [[Feature requests]] page, as follows:


;1. [[Feature requests]] : Features, requirements and requests by country. This page contains verbatim requests from technical leads or translated and reviewed rewrites of initial feedback. Only items specifically requested by a qualified technical lead, administrator, teacher or student in the country should go in this section. See also: [[Deployments]]

;2. [[Feature roadmap]] : Feature suggestions by technical strategy. Each item on this page should include reference to the;Requester: (e.g. country or engineer or URLs to relevant discussions and sites). It should also include a reference to which element of the strategy it fits in to (if available).

Each item on this page should include reference to the;Requester: (e.g. country or engineer or URLs to relevant discussions and sites). It should also include a reference to which element of the strategy it fits in to (if available).

Features are prioritized based solely on their value towards achieving the goals and executing the strategy. The amount of effort required and the availability of engineers to expend such effort is not included in the prioritization decision. The engineering and test work, the availability of relevant software and the available resources will be added as critical decision factors when determining what features are delivered in each release. This page is meant to be abstracted from releases and it should therefore include a superset of priorities for any given release.

==Adding to the roadmap==

This section lists major features to be added to Sugar over time. Each request should use the [[Template:Feature request| feature request template]] (you can copy/paste from below), providing as much information as possible. Direct feedback from countries and deployments should be provided on the [[Feature requests]] page instead.

==Adding to the roadmap==
{{Feature_request
When adding a new feature please follow these guidelines.
|Name=New activities
|Requesters=Birmingham, Juliano
|Requirements=
From Birmingham:
*Firefox, Flash, mplayer
*A spreadsheet (I'm going to use gnumeric until Socialcalc is ready for production)
*A more full featured pdf reader (yes, I know there's the Read activity, but I'm planning on installing the full evince and making sure Firefox can open PDFs with it)
*A document editor the user can insert images into (the full Abiword would be great for this, but the current workaround [after editing a file] is to open write, then hit ctrl+n)
From Juliano:
*More development environments.
*Better Flash support. Minimum on par with FF on XP. From test report by Emiliano and thread on sur list.

# Make sure the feature doesn't already exist
{{Feature_request
# Read the Usage section of [[Template:Feature tracking]] for help filling out the template on the new page
|Name=Browse update and multi-media
# Pick a "Feature subcategory" from [[:Category:Software features]]
|Requesters=[[User:Skierpage]]
# Find the requester(s)' wiki pages and the feature owner's User: wiki page
|Requirements=
# Change ''Good feature name'' to your new subpage title, following the [[OLPC:Style guide]] for page names
* Wikipedia articles and thus [[Wikislices]] can take advantage of this, and richer multimedia in Browse becomes practical.
# Ready? Click the button below to create a new wiki subpage with the right title convention that's prefilled from [[Template:Feature tracking/Preload]], edit it to suit, then save. After a delay (due to wiki query and page caching), your new subpage will appear in lists of features.

|Specification=
; Requesters : Deployments, engineers, or both who support the request
* [[XULRunner]] 1.9.1, the Mozilla code powering [http://developer.mozilla.org/en/Firefox_3.1_for_developers Firefox 3.1], should be released in the 9.1.0 timeframe.
; Requirements : User level requirement definition; Links to detailed wiki pages, mailing list threads, or other resources are welcome
; Specification : Design and technical implementation ideas; Links to detailed wiki pages, mailing list threads, or other resources are welcome
; Owners : Names of developers and/or champions of the request who will ensure that progress is made
; Priority : 1-5 (1 = Critical, 2 = High, 3 = Medium, 4 = Low, 5 = not needed)
; Helps deployability : yes or no Better deployability is the goal of [[9.1.0]]. Set to "yes" if the feature helps that goal, regardless of its "target 9.1.0" status.
; Target for 9.1 : yes or no "yes" means that an OLPC engineer is (or will be) assigned to work on this for 9.1.0 release.


See also: [[#Suggestions for providing input|general suggestions for providing input]].
* Activities and content can use its new features, at the risk of incompatibility with earlier Sugar releases.


=== Adding a category ===
* XULRunner 1.9.1 supports the HTML5 <audio> and <video> tags, providing the ability to play [[OGG]] audio and video files natively in the browser.
Only do this with careful forethought and a confirmation on the wiki gang list http://lists.laptop.org/pipermail/wiki-gang/>
This will probably improve performance and reduce memory footprint compared with embedding the [[Totem plugin]], the trade-off needs to be tested and Browse configured accordingly.


1. Mention the new category name in the template:
|Owners=
|Feature subcategory=''Easter eggs''
}}
2. Be sure to create the subcategory: edit the category's page (Category:''Easter eggs'') and add
<tt><nowiki>[[Category:Software features]]</nowiki></tt> to it.


If you forget #2, some queries will omit the page and people may have a hard time finding your new feature subcategory.
{{Feature_request
|Name=Single Sign on from Browse
|Requesters=Reuben
|Requirements=
* Must allow XOs to pass their identity to the XS so that the XS recognizes them without the need for them to login.
* Must pass that info in Browse in such a way that the XS HTTP server can recognize and extract the info for use in CGI scripting.
* Must be encrypted and unique information so that other browsers can't "spoof" and appear to be the XO.
* Must work with the back and restore feature so an XO and only the relevant XO "automatically" see and restore their own backed up files.
|Specification=
|Owners=Greg
}}


=== Documentation on semantic templates ===
{{Feature_request
{{SMW for software features}}
|Name=Better eBook reader
|Requesters=Birmingham, Haiti, Devel thread
|Requirements=
* Description of challenges here: http://lists.laptop.org/pipermail/devel/2008-October/020662.html See the rest of the thread too.
*A more full featured pdf reader (yes, I know there's the Read activity, but I'm planning on installing the full evince and making sure Firefox can open PDFs with it) (comment from Birmingham)
* Must not copy the PDF or other book format so that it takes up twice the NADN space.
* Must support PDF, plain text and .cbr files (any other must have formats?)
* Must open book directly from Journal
* Must "remember" the page you are on when restarting.
* Must allow opening the reader then browsing available books (can do this in web browser but needs the ability to look at the NAND to see what is available).


When you fill in [[Template:Feature tracking]] on one of the feature roadmap sub-pages, the template both ''displays'' the feature's information in a basic table (using {{tl|Definition table}}) and makes ''semantic annotations'' for many of the template fields &mdash; assigning values to properties such as [[Property:Requested by]]. That allows this page and others (such as [[Features-test]]) to query for and display these properties.
Desired improvements
* ability to do page mode as well as continuous mode (move an entire page at a time)
* ability to specify columns and move through a document down the columns
* ability to specify the amount of overlap when paging in continuous mode
* ability to zoom to 'fit text on screen' as opposed to 'fit page on screen' to eliminate borders from pages.

{{Feature_request
|Name=Sugarized color picker
|Requesters=Juliano
|Requirements=
A better color picker in Paint & Write. Current one "...is made for professionals to get the HTML code of the color, but it also leads to error since people need to select the color in the circle and then in the triangle. It is giving bad time to people around here [Rwanda]". ''From Juliano in e-mail 9/1''
|Specification=
|Owners=

{{Feature_request
|Name=Easy "Sugarization"
|Requesters=Wanda, David
|Requirements=
* Support for standard desktop applications in Sugar.
* Better "legacy app" compatibility; this should allow us to run existing apps like firefox, pidgin, and gimp in a reasonable manner (CScott version).
* Make it easy to sugarize third party applications. It should be trivial to take an existing application which runs on Fedora (or other Linux too?) and install and run it on the XO. The basic sugarization interface for that should be usable by a non-programmer. Not all sugar features need to be enabled (will define exact list if this gets to requirements definition stage). Additional sugar capability may require programming (e.g. collaboration). The goal is to allow deployments to use any state of the art application available in Linux/Fedora.
* Secondarily, make it easy to do the same for web based applications (Google Gears, Picasa, etc.). tbd if this needs to include client side Java support.
* Allow easy creation of content bundles out of PDFs and HTML (other?). Should be as easy for a non-programmer as that described above.
* Must "work well" in Sugar. There may be some applications that work but don't use the journal (e.g. Scratch) and that may be acceptable. A definition of how well an activity works or a definition of "well sugarized" is needed. First comments on this are at: http://wiki.laptop.org/go/Educational_activity_guidelines
* Product management and Learning teams must come up with 5 - 10 applications which will be the first targets.

|Specification=
* See related X-windows threads on devel (links and references appreciated). This may also impact datastore and other areas.
* Replace matchbox window manager with [[XMonad]], [http://en.wikipedia.org/wiki/Metacity Metacity], [http://awesome.naquadah.org/ awesome], etc. Should provide both 'full screen' mode and traditional 'tiled' mode.
* Switch to standard freedesktop.org [http://www.freedesktop.org/wiki/Specifications/startup-notification-spec startup notification] mechanism: <trac>5271</trac>
* Implement freedesktop.org [http://www.galago-project.org/specs/notification/index.php notifications mechanism] for alerts (low battery, low disk space, available software update)
* Refactor home/friends/mesh view as operations on root window, so they make sense in a multiwindow setup. (It's been suggested that looking at the xpenguins code is instructive for understanding how nautilus,etc arrange their root window.)
* App launching & mimetypes via XDG mechanisms (thanks, erikg)
* Support for .desktop files in the launcher list
* Support startup-notification
* Support standard application icons on the frame
* See also thread by Scott: http://lists.laptop.org/pipermail/devel/2008-October/020387.html

== Power management ==

{{Feature_request
|Name=Improved battery life
|Requesters=Kim, Carla, Gnu, Ethiopia, Juliano
|Requirements=
Background information: a list of UI actions which may affect power usage: [[Requirements#Power Management Requirements]] Our job is to increase battery life in as many modes as possible.

<br>
# Power save (here after called idle suspend) should default on but the user also the option to not use it.
# When you turn the radio off the in the network control panel it must cut off all power to the wireless chip.
# Must rewrite the documentation on power and explain it to Frances so that she understands how to use it. (add link to existing documentation).
# Should offer a full featured set of power options in GUI. Not critical but nice to have.
# Idle suspend must dim the screen after 1 minute of the user not touching the keyboard or touchpad. Then after an additional 2 minutes it must change the screen completely off. Must allow setting of those values in the control panel. The only exceptions are that when the audio device is playing, when olpc-update is running.
# Must turn the screen back on in less than 1 second after the user touches the keyboard or touchpad.
# Idle suspend must turn the CPU off.
# Must allow activities to override the idle suspend mode above. That is to not suspend even if the time has passed.
# Must not lose your network connection, activity state, sugar GUI elements and collaboration (e.g. start a chat, let the XO suspsend then otehr chat person chats, that new chat text should show on the suspended XO without turning on the screen) after waking from idle suspend. Must not crash. Multicast, ARP, mDNS, the Presence Service, and collaboration must all work in the presence of autosuspend.
# Should not turn the screen on unless the user interacts with the keyboard.
# Wireless chip must respond to ARP requests when in Idle Suspend mode.
# Screen must not flicker on resume.
# Should allow users to disable the mesh: reduces power consumption of the WiFi chip, allows the WiFi chip to enter power-save mode, and most importantly, allows lid-closed suspend to totally power off the WiFi chip. <trac>6955</trac>
# Should put the EC into deep sleep when in a lid-closed suspend. This will cut its power from about 60ma to about 20ma (check with rsmith), which would further increase the duration of a lid-closed suspend before the battery drains.
# (* not likely to make 9.1 with current resources *) Should improve cpu idle detection. Currently we can't auto-suspend very often (only after >1 minute of no user interaction) because suspend is so heavy-handed. The cpuidle infrastructure in the kernel should be able to tell us when it's safe to suspend because no process wants access to the CPU for the next few seconds. Most of the pieces are there.

|Specification=
Requirement 4 addressed by: <br>
<trac>2765</trac> -- Need to turn off DCON after some time in idle suspend <br>
<trac>4606</trac> <br>

Requirement 5 addressed by: <br>
<trac>9054</trac> -- Speed up USB resume (kernel)
<trac>7981</trac> -- EC mask setting is inefficient
<trac>8916</trac> -- Extreme Power Management doesn't unload USB for fast resumes
<trac>7384</trac> -- Manually enabled USB-disabling Power Management

Requirement 9 addressed by: <br>
<trac>6818</trac> -- Make the multicast wakeup filter work with collaboration (Ricardo Carrano?)
<trac>7458</trac> -- Intermittent lockup on WOL

Requirement 10 addressed by: <br>
<trac>3732</trac> -- ARP broadcasts don't wake auto-suspended laptops

Requirement 11 addressed by: <br>
<trac>7958</trac> DCON flicker on resume (kernel regression; perhaps Deepak, Andres, Mitch, or Adam Jackson?) <br>

Other: <br>
* <trac>9055</trac> -- Create 9.1 test plans for automatic power management

* There's still a major Python bug that causes multi-threaded pyGTK2 programs to poll uselessly once a second (<trac>4680</trac>, <trac>4677</trac>). Much work was done to close it, but there is still a small sprint required to get it done. This not only reduces power use directly, but also allows the system to suspend because it doesn't appear that activities need to do some work soon.

Background on power draw including a break down watts used in different modes:
* [[XO Power Draw#The Numbers]]
* [[Per-Activity Power Usage]]

Significant technical actions (as suggested by John/Gnu) that could reduce the laptop's power draw:

* not to Greg - move to collaboration.
* Reduce packet traffic during sharing -- particularly multicast traffic, which loads many machines (and wakes them up from autosuspend). This will require diagnosis and improvement of the presence and collaboration protocols. Some work was done on this, after the high packet traffic melted the WiFi bandwidth in early deployments (e.g. turn on 30 laptops in the mesh, none of them can usefully get anything done), but our main response was to tell later deployments "Don't use the mesh, use access points" -- a significant reversal that we should keep working to fix.

* Fix tubes so that peer to peer data is sent with peer to peer connections on the network where possible
* Fix the way JIDs are allocated to be more coherent and based on the child's nickname (also would benefit a lot from having hierachical DNS naming on the school server so each JID is globally unique)
* Expose JIDs in the UI and allow them to be typed in and approved by normal subscription requests, allowing collaboration with anyone whose JID you know
* Implement the Telepathy file transfer spec to enable that feature in Sugar
* Enable avatars in Sugar (although maybe not if we're doing link-local multicast on an XO mesh network) and maybe some UI for taking a photo and setting that as your avatar

|Requesters=Peru blog http://blog.stone-head.org/olpc-peru-a-silent-revolution/
|Requirements=A way to send objects from one XO to another without a USB key, and without sharing the activity. <br>
See also: http://wiki.laptop.org/go/Network_principles#Direct_XO-to-XO_serverless_communication. <br>
Greg's requirements definition: <br>
* Must allow moving an "object" (usually thought of as a file) from one XO to another.
* Must support all available network environments (e.g. Mesh, AP only, XS eJabberd)
* Should allow transferring files using the existing Sugar Neighborhood tools (e.g. put a file on the journal of any other user visible in the network neighborhood).
* Should allow moving an object to any XO visible over the network (AKA pingable) regardless of whether they are visible in the Neighborhood (due to bugs in collaboration or someone not collaborating or any other barrier which does not prevent ping).
* Should support queuing a file for transfer later. That is, add support for asynchronous sharing over time : the sharing of an effort should not require everyone to be online at once.
* Using file transfer must work in both Salut and Gabble,
* Allow Journal objects to be shared between buddies over link-local or Jabber
* Enable automatic activity downloading for shared activities that aren't installed on the joining machine

|Specification=
(I believe this needs to be divided into 'customization key' and initial install. The install has to do with the logistics, USB keys and wireless downloads. Customization has to do with how the image is created before the logistics of how to get it on laptops. [[User:Kimquirk|Kimquirk]] 17:25, 9 October 2008 (UTC))

Many deployments have noted how hard it is to install or upgrade, especially on thousands of XOs. One issue is that inevitably, the Xos ship from the factory with an older build and countries need to upgrade them before deploying. I call that "upgrade in a warehouse". In other cases the XOs get deployed but there is little or no WAN available to upgrade.
|Owners=
}}

{{Feature_request
|Name=Faster imaging
|Requesters=Ethiopia, Rwanda, Haiti
|Requirements=
This feature request is needed to minimize the time to install a custom image over a wireless or wired network. It will be used when an XO comes from the factory with an older release. The deployment then needs to upgrade to the latest release and possibly install some customizations (e.g. content, language pack, activities, see also separate customization requirement below). The solution must be faster than imaging via USB sticks for imaging more than 1,000 XOs. Must allow install of new image via wireless or wired network. Possibly sub-variants of in school case for Mesh, Wireless AP, XS.

Workflow example for the network case above: <br>
# XOs leave the factory with an older image (e.g. 8.2.1) which includes this OFW code.
# A custom image based on the same or a later release including activities, content, language and maybe other customizations is prepared and loaded on the XS.
# An AP is setup and wired to the server.
# The XOs are turned on, as many as they have power jacks for. On boot up we can require that they hold down some special keys (game keys).
# Release the keys and the XOs find the AP and start listening on preconfigured multicast broadcast address.
# The XS broadcasts on the preconfigured address and each XO starts receiving.
# In case of errors which are more than what can be recovered by error correction the XOs, pick up again on the second broadcast or third or up to ... n (where is configurable or they just turn t he server off).
# When the XO has a complete image it notifies by putting a special image on the screen.
# On next reboot of the XO its running the new image. Subsequent boots do not do this multicast listening unless configured specifically by the user.
|Specification=
See also: [[Multicast NAND FLASH Update]]<br>

Some open issues to be addressed by the design proposal:
* Do we pre-configure an ESSID and multicast addresses and hard code those in the factory?
* Can we get it down to no intervention of hold down games keys only?
* What happens if you turn on "too many" XOs? Can we just let them turn on as many as they want and we'll fill them in some order or should we
limit it to set # of XOs at a time? Can we scale it by using more "channels" or more APs?
* Any other security points?

{{Feature_request
|Name=Activation lease security
|Requesters=Peru, Ethiopia (especially last point), Uruguay?
|Requirements=

'''Overview''' <br>
The controlling idea is that when an XO is stolen it will stop working after a time (activation lease time) unless it contacts a re-leasing server (usually a School Server). For example, if an XO is stolen and taken away from its school server, after the expiration of the lease time it will no longer boot up. If the XO is stolen but still comes within range of its school server, it can still be prevented from booting if the XO information (probably serial number) has been added to a black list on the XS.

* If the laptop is stolen, and doesn't contact its local school server within some period time (activation lease time) the XO will no longer boot (I call this "deactivated").
* Si se roba el XO y el XO no se contacta a su servidor (XS) local de la escuela dentro de una cierta hora del período (tiempo del arriendo) el XO va a encender (boot) (llamo este " deactivated").


* When the XO boots up and contacts the XS, its lease time is extended. e.g. if the activation lease time is 30 days and it starts on November 1, then the XO boots up on November 20 and contacts the XS, it will continue functioning without contacting the XS until December 20.
* Cuando el XO arranca y entra en contacto con el XS, su tiempo del arriendo es extendido. e.g. si el tiempo del arriendo de la activación es 30 días y comienza el 1 de noviembre, después el XO arranca el 20 de noviembre y entra en contacto con el XS, él continuará funcionando sin entrar en contacto con el XS hasta el 20 de diciembre.


* Optionally as set by the administrator, if an XO is deactivated and tries to boot up when in the vicinity of its controlling school server, then it will boot unless it has been added to a blacklist. The blacklist is a list of XOs (by serial number?) which has been entered in to the school server by its administrator. That is, the activation lease time will be automatically extended whenever the XO contacts its controlling XS, unless it has been entered in the black list.
* Opcionalmente como fija por el administrador, si un XO se desactiva e intenta boot cuando esta en la vecindad de su servidor de la escuela que controla, después boot a menos que se haya agregado a una lista negra. La lista negra es una lista de XOs (por número de serie?) cuál ha sido entrado adentro al servidor de la escuela por su administrador. Es decir, el tiempo del arriendo de la activación será automáticamente cuando el XO entra en contacto con su XS que controla, a menos que no se haya inscrito en la lista negra.


* Must allow setting of the activation lease time by the deployment lead (user interface required). That is, they can set it for 90 days or whatever they want. The granularity should be at 24 hours and be from 1 day to never expire. Must allow setting this once for a recurring interval (e.g. XO leases expire every 60 days).
* Debe permitir el ajuste del tiempo del arriendo de la activación por del despliegue (interfaz utilizador requerido). Es decir, pueden fijarlo por 90 días o lo que quieren. La granulosidad debe ser en 24 horas y ser a partir de 1 día nunca a expirar. Debe permitir el fijar de esto una vez para un intervalo el repetirse (e.g. los arriendos de XO expiran cada 60 días).


* Must not be possible for the user to set the date on the laptop to keep it within the lease period or to force it to outside the lease management. This might mean you cannot change the date or there is no root access, or it might mean an alternate time source is used.
* Necesidad no ser posible para que el usuario fije la fecha en el ordenador portátil para guardarlo dentro del período del arriendo o para forzarlo fuera de la gerencia del arriendo. Esto pudo significar usted no puede cambiar la fecha o no hay acceso a root, o puede ser que signifique que una fuente alterna del tiempo está utilizada.


* Must support the same as described above but allow the server which determines the activation to be across the Internet. The lease management server can be in a data center managed by the deployment or on a server managed by OLPC.
* Apoye iguales como se describe anteriormente pero permita el servidor que determina la activación para estar a través del Internet. El servidor de la gerencia del arriendo puede estar en un centro de datos manejado por el despliegue o en un servidor manejado por OLPC.


* Must support the same requirement as described above but allow the reset of the activation to be done via USB key. That is, when an XO's lease expires, it must be booted with the USB key containing a special code. This can be done before it expires to extend the lease.
* Apoye el mismo requisito como se describe anteriormente pero permita que el reajuste de la activación sea hecho vía llave del USB. Es decir, cuando el arriendo de un XO se expira, él se debe boot con la llave del USB que contiene un código especial. Esto puede ser hecha antes de que expire para extender el arriendo.


* Should support the ability for an XS to continuously generate new leases every nnn time as set by the user (e.g. every 2 weeks). This will allow an XS to be placed in a school and then it does not need Internet access or anyone from outside the school to continuously update the lease times.


* Should support a GUI accessible from the XO which is password protected and encrypted (aka no passwords in the clear across the network/wireless). This GUI will allow a user in the school to enter an XO by serial number or better by name and have that XO added to the blacklist (see above, essentially its lease is not renewed).

{{Feature_request
|Name=Theft reporting

|Requirements=
Sometimes known as 'active kill'. If the laptop is stolen, the serial number can be added to a 'stolen laptop' list so the laptop's activation can be turned off the next time it finds either a local school server or a global tracking server.

* A trusted administrator can log into a central system (either regionally controlled or OLPC controlled) and add a serial number to the 'Stolen' list.

* Any laptop that connects to a local or global server that finds a match on the 'Stolen' list, and it was originally activated with an activation key, will be de-activated.

* The security must ensure that the person adding the stolen laptop is a person who has been given that access; and that the server causing the de-activation is a server that has been given that right.

* List of URLs being accessed
* List of URLs per laptop
* Which activities are being used per laptop
* Number of minutes in each activity per laptop; can we determine (and subtract) idle time?
* Number of minutes in each activity within and outside of school hours (perhaps this means we capture the 'start' time of each activity and allow the reporting to decide if this is during or outside of school hours).

This is not as high priority for their deployment as the passive lease management, but I believe this feature will be important for any deployment. We should try to get feedback from other deployments as to the information we want to collect.

In addition, I'd like to support a community driven help system by which, in addition to the activity/olpc provided help, it's possible for kids to add tips, tricks, images, tutorials, and other info to these sections for later consumption by peers.

This is a noble, but ambitious goal, which is why a simple and static help activity is the present solution, and why it's only integrated into the system at a single point - the activity itself.

{{Feature_request
|Name=Scalable zoom levels

|Specification=Gadget is the core of this effort. We need some additional UI work to hook it up. One aspect of the solution is the addition of list views to all zoom levels, making it possible to list the entire set of people, activities, access points etc, see their icon and name at a glance, sort alphabetically or by type, and also filter as desired.

{{Feature_request
|Name=Keyboard navigability

|Requirements=All options in the menu and frame should be accessible from the keyboard (ctrl-xxx). There should be some way to see what key is associated with a given option, both when using it and when "looking for the key". This should require a minimum (ideally, zero) programming from activity developers. This is a key part of the strategy for improving the situation of bad trackpads; it is unrealistic to expect the trackpad problem to be 100% resolved.
|Specification=Holding the control (or frame) key should show semitransparent letters/numbers over any menu (or frame) gadget visible. These letters should also appear for ~150 ms when an option is chosen. Default letters should be chosen by the relevant python classes if not specified by developer. Any specification should be localizable. Ideally, contextual menu options should be accessible with multiple keystrokes.

{{Feature_request
|Name= Replace JFFS file system with better one
|Requesters= Deepak
|Requirements=
* End users will see faster boot up time and will not see (as much) performance degradation as the file system fills up.

|Specification=
The current file system used on the XO ([[http://en.wikipedia.org/wiki/JFFS2 JFFS2]]) was developed in the days of 32/64MiB NOR flash devices and does not scale well to the 1GiB NAND devices we are using today and certainly will not deal well with larger devices in gen 1.5 and gen 2 systems. The main issues are that JFFS2 needs to scan all blocks at mount time and that the garbage collection algorithm increasingly consumes CPU cycles as the system fills up. The first issue manifests itself as large delays at boot up to mount the file system as it is full (need to quantify this), and the second issue simply means less CPU cycles can be dedicated to user task processing. In the last few years, there has been much activity in the embedded Linux world on alternatives to JFFS2 and we need to investigate these to determine which one best fits our needs:

* [http://www.yaffs.net/ YAFFS2] : Has been around for several years and in active use in the embedded space. It does not provide compression out of the box as the devices that use it often carry already compressed data such as MP3 and MPG files.

* [http://www.linux-mtd.infradead.org/doc/ubifs.html UBIFS]: A new file system recently merged into the kernel designed for use on large flash devices. Supports compression out of the box and supports disabling compression on a per-inode basis, which is something we desire.

* [http://logfs.org/logfs/ LogFS] : Another JFFS2 replacement designed for fast operation and scalability. Still fairly new and not in very active use AFAIK.

* [http://btrfs.wiki.kernel.org/index.php/Main_Page Btrfs] : A very new file system that is primarily targeted for large storage systems with features such as snapshotting, RAID support, and online fsck. David Woodhouse has expressed that he will look into getting this to work on NAND, but it is too new of a code base to consider for 9.1

* Managed NAND : (Not an option for existing XO machines, but might be a direction for future hardware) The industry seems to be moving away from raw NAND in favor of a NAND-chip plus microcontroller solution. The microcontroller implements a Flash Translation Layer that hides the low level NAND details, presenting a higher level interface that looks like an ordinary hard disk, so an ordinary filesystem layout like ext3 could be used. The driving force behind managed NAND is rapid hardware evolution toward multi-level-cell NAND chips and smaller process geometries, which change important NAND parameters like page sizes and ECC. The situation is similar to what happened with hard disks in the 80's, where raw-disk interfaces gave way to SCSI and IDE, which hide the ugly low-level details that changed every technology generation. Managed NAND options include LBA-NAND from Toshiba (pin-compatible with NAND chips), eMMC from multiple vendors (with an SD/MMC-compatible hardware interface), and various "disk on chip" products (IDE-compatible interface).

'''Development process''' <br>

* Analyze and quantify the use patterns that trigger issues with JFFS2.
* Gather requirements for a new file system that go beyond solving above issues.
* Develop/integrate a set of tests for FS performance and reliability that take into account our use patterns, the above issues, and any other features we wish to validate.
* Study the three main alternatives (YAFFS, UbiFS, LogFS) to determine what requirements they meet
* Run our FS test suite on above alternatives
* Analyze test results and requirements study and make a decision on which alternative to use.

'''Deployment process''' <br>
Once a file system is chosen from the above process, we will have to: <br>
* Integrate the file system into our kernel if it is not upstream (YAFFS2 or Logfs)
* Integrate the file system support packages into our build system and file system images
* Update our build scripts to generate the proper image type for

'''Activity impact''' <br>
This change should not have any impact on activity developers as it is at a very low level of the stack.

'''End-user impact''' <br>
End users will see faster boot up time and will not see (as much) performance degradation as the file system fills up.

How do other parts of the system (the Journal, Browse, other activities) see and interact with these three collections of material (to browse and copy the code, to view the static content, to aggregate the resource collections with other collections)?
* a [[Dynamic library]] implementation
* coordination of a unified help interface building on top of the library bundles defined for each activity on the system.
** integration of some way to update and share this. related to how to leave a comment on/about an activity or file/resource
* coordination of local library bundles, and regional caches of viewed material, school server caches of bundles, and web caches.

Suggestions from Scott below <br>
* The current API is a mess, doesn't match the documentation on the wiki, is inconsistent with the activity.info format, etc.
* Merging content and activities -- a bundle ought to be able to have *both* a library.info *and* an activity.info
* Using a content format which is consistent with "offline internet" content -- more or less consider installing content files as pushing stuff into an offline cache

{{Feature_request
|Name= Developers Center w/ documentation for users and developers
|Requesters=[[User:Mchua|Mel]]
|Requirements=
Strictly speaking, this is not a technical feature; however, like technical features, this would require developer time in exchange for enhancing our capabilities to implement and (commercially) support technical features, so I am including it here.

* A separate, non-community-maintained, website for formal user and developer documentation (Precedents: [http://www.redhat.com/developers/ Fedora/Red Hat], [https://help.ubuntu.com/ Ubuntu]), posted in a publicly viewable but edit-protected place. (i.e. not publicwiki as it now stands.)
* On this site, a canonical list of all the technical subcomponents that make up the OLPC system that the organization supports.
* For each subcomponent, a howto/code-tour for the kind of developers we want to have working on that portion of the project.
** Note that this could be "Code is available for download, but community development is not officially supported by the OLPC organization," and a link to the all-community wiki (or appropriate pages as on SugarLabs).
* Intended audience: developers with code experience but no OLPC-specific project background
* Put a link in the library on the XO which links to GIT or other relevant source. (added by Gnu)


|Specification= If this were implemented mainly by developers, it would be a large task for the developer responsible for each subcomponent to take responsibility for creating this section. So instead, I would suggest putting the load on a single editor who would be in charge of talking with developers, asking them questions, and formatting their (objective: minimize the workload on developers as much as possible). I could see this being half-time contract work, maybe for 2-3 months during 9.1 development, to create and release a first version of a "developers' center" with an infrastructure that can be easily updated for future releases.

=== 1. The datastore ===
Sugar's design calls for a centralized rich data storage system, the
datastore. The datastore provides secure, limited file access to
Activities, manages file metadata, maintains a differentially compressed
history of all work, ensures reliable backups to a trusted server, and
mediates the connection to removable media. Every one of these features
is crucial to Sugar's functioning, and almost none are really working at
this time. We cannot afford another release based on the present
datastore, as it fails to implement the features we require, and is
unreliable even in the features it supposedly implements.

Solution: <br>
There have, at this point, been at least five distinct proposals for a
next-generation datastore design, all differing in underlying
implementation and user-facing functionality. We need to have a Once And
For All datastore summit, draw up a compromise datastore design, and
implement it. We can do this by 9.1.0, if we are willing to make it a
priority.

=== 4. Activity Modification ===
A keystone of the Sugar design has always been the user's ability to edit
any Activity, and to cement this a "View Source" key was designed right
into the hardware. This functionality is simply missing, and that
prevents us from making our principal claim regarding an emphasis on user
modification.

Solution: <br>
"Develop" must be polished, finished, and included by default. This will
require modifications to the core system, in order to support an endless
variety of slightly modified Activities. It will also require work on the
Develop program itself. If volunteer efforts are not moving fast enough, OLPC
must ensure that someone is working on the problem as a professional.

* [[View_Source|Current status of "view source"]]
* [[OLPC_Human_Interface_Guidelines/The_Laptop_Experience/View_Source]]
* [[EAG_The_Laptop_Experience:_View_Source]]

=== 5. Bitfrost ===
Sugar, as it currently stands, is among the least secure operating systems
ever, far less secure than any modern Linux or Windows OS. I can easily
write an Activity that, when run by the user, escalates to root privileges
and does anything I like with the system. Given Sugar's competitive
status against Windows XO, this failing threatens the very existence of
the project. The Sugar designs have long stated that safely running
untrusted code from a classmate is a key goal for learning, but the
current software accomplishes precisely the opposite.

Solution:<br>
NO ONE IS WORKING ON BITFROST. That's right. Everyone who was working on
Sugar security (after activation) has either left OLPC or moved into
another role. Someone must be assigned to continue the security work, or
it will certainly never make progress. Anyone who _does_ take on this
challenge will start from a much better position than previously,
because many of the Vserver features have moved into the mainline kernel
over the last few versions. The kernel now contains a number of new,
powerful isolation and control primitives.



== Thoughts from [[User:cjb]] ==
* Translation of Sugar inside Sugar?
* A working Distribute activity for journal objects (could be in the Journal)

== Thoughts from [[User:Mstone]] ==

* [[Security]] already contains my immediate security roadmap.
* My [[User:Mstone|user page]] links to several of my other ideas, many of which are procedural improvements with software components.
* My largest ongoing concern is that we have not yet smoothly carried a deployment through an update to a new major stable release. (Peru may become our first exception to this rule, but this remains to be seen.)

Overview

This page goes hand-in-hand with the Feature requests page, as follows:

1. Feature requests
Features, requirements and requests by country. This page contains verbatim requests from technical leads or translated and reviewed rewrites of initial feedback. Only items specifically requested by a qualified technical lead, administrator, teacher or student in the country should go in this section. See also: Deployments
2. Feature roadmap
Feature suggestions by technical strategy. Each item on this page should include reference to the;Requester: (e.g. country or engineer or URLs to relevant discussions and sites). It should also include a reference to which element of the strategy it fits in to (if available).

Suggestions for providing input

  1. Please sign in to the wiki when updating this page and its subpages so we know who made the edits.
  2. Raw, unfiltered feedback from countries and deployments should go on the Feature requests page.
  3. Feel free to add to this page following the guidelines described above. You can add a subsection to #General comments below, or add to this page's discussion page.
  4. To comment on a particular feature, click the feature's title to go to its subpage, then comment on its discussion page.
  5. Before editing the subpage for a particular feature, , discuss your edits with the original poster /owner beforehand.
  6. You must use the template correctly when requesting features or enhancements, otherwise your feature won't show up. Follow #Adding to the roadmap carefully
  7. Use <trac> when referencing tickets/bugs.
  8. Additional suggestions for providing input are welcome.
  9. Create a new section (At the == header 2 == level) for your country or request if none present are adequate.
  10. Make sure all ideas have a very solid basis for being valuable to customers. Including links to blogs, reports or other data that proves users really need your feature will make a big difference.

Other queries

Feature roadmap/Page of all features that target 9.1.0 embeds all the pages with Target for 9.1 set to "yes".

See Features-test for other queries, you can add your own to it or copy them to other pages.


Adding to the roadmap

When adding a new feature please follow these guidelines.

  1. Make sure the feature doesn't already exist
  2. Read the Usage section of Template:Feature tracking for help filling out the template on the new page
  3. Pick a "Feature subcategory" from Category:Software features
  4. Find the requester(s)' wiki pages and the feature owner's User: wiki page
  5. Change Good feature name to your new subpage title, following the OLPC:Style guide for page names
  6. Ready? Click the button below to create a new wiki subpage with the right title convention that's prefilled from Template:Feature tracking/Preload, edit it to suit, then save. After a delay (due to wiki query and page caching), your new subpage will appear in lists of features.

Target for 9.1
yes or no "yes" means that an OLPC engineer is (or will be) assigned to work on this for 9.1.0 release.

See also: general suggestions for providing input.

Adding a category

Only do this with careful forethought and a confirmation on the wiki gang list http://lists.laptop.org/pipermail/wiki-gang/>

1. Mention the new category name in the template:

Feature subcategory=Easter eggs

2. Be sure to create the subcategory: edit the category's page (Category:Easter eggs) and add [[Category:Software features]] to it.

If you forget #2, some queries will omit the page and people may have a hard time finding your new feature subcategory.

Documentation on semantic templates

Enables a dynamic Feature roadmap — see Semantic MediaWiki#For software features.

When you fill in Template:Feature tracking on one of the feature roadmap sub-pages, the template both displays the feature's information in a basic table (using {{Definition table}}) and makes semantic annotations for many of the template fields — assigning values to properties such as Property:Requested by. That allows this page and others (such as Features-test) to query for and display these properties.
