Lots of good ideas are listed in [[:fedora:SummerCoding/2008/Ideas|Summer Coding Ideas (Fedora Wiki)]]. These projects were originally proposed for Google Summer of Code projects; if you want to use one of them, please discuss it with [[User:Chris Tyler|Chris Tyler]] before selecting it, because the scope and mentorship model for GSOC is different from that of the LUX projects.

== Cobbler Web ==
 +
 
 +
Cobbler is a Linux install server that simplifies tasks associated with fully automated installation such as DHCP, DNS, kickstart, yum, and virtualization.  It aims to be a universal install server for all linux distributions.  Currently Cobbler has a web interface that allows users an easier way of interacting with cobbler.  There are several core improvements that can be made.  One idea is to extend cobbler web to produce views that make it easier for users to edit fields that only they edit (let me reinstall systems I own but don't show me fields I shouldn't care about).  Another is to enable search features in the web app to make it tolerate thousands of systems to a better extent.  Finally, another feature is to add a task engine to cobblerd, to make it possible to run commands like "cobbler import" and "cobbler reposync" in the background and see their output in the web interface via an AJAXy type system.
 +
 
 +
Possible features are not limited to the above (or just working on the web interface), Cobbler has an ongoing RFE list in Trac that has a wide variety of potential ideas, and ideas beyond the ones listed are also fair game.  See https://fedorahosted.org/cobbler/report/1?sort=type&asc=1

Koji Personal Repos (KoPeR) is a concept to allow Fedora maintainers to create personal repos of packages to build against and share with others.
  
−
The canvas3d extension is a binary C++ component that adds a 3D OpenGL drawing context to the HTML canvas element. Currently canvas3d works only on Windows.  Port the code to Linux and/or Mac OS X.  Porting involves implementing a pbuffer class for each new platform.  Some familiarity with OpenGL, or a willingness to learn it, is required.

== Add OpenID support to Bugzilla ==
+
== Port Wubi to Fedora ==
  
−
Many open source projects rely on bugzilla for bug tracking, and open source developers use different instances, forcing them to have multiple logins.  Complete OpenID support in bugzilla.
+
If upstream is willing to integrate it, port wubi-installer and make it more cross distribution. Otherwise, provide a similar implementation for Fedora.

scale, the grid topology - what happens when two nodes are behind firewalls.

Use the canvas element in order to create a generic front-end for data visualization of the Mozilla source.  Many types of information about the Mozilla project can be keyed to the source tree.  For example, file change-rates, code-coverage, bug activity per module, checkins per module, etc.  The visualization will be a heatmap, showing certain types of activity in the tree.  Doing this visualizaiton using canvas3d would allow for a third axis, and changes over time to be shown.

== Create Test Suite for Condor ==
  
−
Create a data-source for the Mozilla Tree Visualization project. This means data mining cvs.mozilla.org, bugzilla.mozilla.org, bonsai.mozilla.org and preparing the data for use in a heatmap visualization.
+
Along with a good build infrastructure, a strong test framework and
 +
methodology is key to survival of modern software. Condor is a system
 +
that is shipped on, currently, 14 different platforms - OS + Arch
 +
combinations. New features need to be verified to work on all those
 +
platforms and shown to cause no regressions in other features. Condor
 +
has a large test suite, but no suite covers everything or in sufficient
 +
depth. Pick a few features, say the VM Universe or Concurrency Limits,  
 +
and demonstrate full understanding of them by testing all of the corner
 +
cases. This is far from a simple task, and requires more than a cursory
 +
understand of the system to properly complete. Understanding the complex
 +
interactions of distributed components, common patterns exist across
 +
many distribute systems, as well as intimate interactions with the OS is
 +
key.

== Plugin-watcher ==

Resource: [[:fedora:Nightlife|Nightlife wiki page]], Matthew Farrellee

Firefox sometimes gets a bad reputation for crashing or locking up when a plugin such as Adobe Flash or Windows Media Player causes the problem. Add code to Firefox (or write an extension) so that when a plugin misbehaves, a dialog is presented informing the user so that they can take corrective action (disabling the plugin) or filing a bug with the right party (this warning could be similar to the warning that appears when a JS script in a web page hogs too much CPU time. As a minimum it should identify that a plugin is to blame; better would be to inform the user of the plugin's name; best would be to provide an option to temporarily disable the plugin).

== Improve Mozilla Application and Platform Documentation ==
+
== Review Packages ==
  
−
Not enough is understood about the various communities and companies who develop with Mozilla, as opposed to those who work on the Mozilla code itself. A proper survey needs to be conducted in order to find out which APIs are being used and how, what is hard, what could be improved, etc. The [http://www.mozpad.org Mozilla Platform Application Developers] is interested in changing this.  Their goal is to work with the Mozilla development community to survey, understand, and document the current state of the art.  In this project you will work with the mozpad community to connect with projects/companies in orbit around Mozilla and do interviews with their developers.  You will then document this information.

There is a lot of packages in Fedora waiting for someone to review it. While a completely new Fedora contributor needs to be sponsored before his package is approved, subsequent packages can be reviewed and approved by any Fedora package maintainer. In addition to that, virtually anybody with a Red Hat Bugzilla account can do do unofficial reviews. Working through the review queue and doing this work might be fun and useful learning process for folks interested in RPM and packaging in general.

== My Favicons extension  ==
+
Currently it requires many many steps to produce another language of Firefox.
 +
It would really easy to package these many steps to reduce the required knowledge to generate a new language.
  
−
Write an extension to allow the user to pick his/her own favicons for sites, based on a URL regexp.  The image should get stored as part of the user’s profile, so that it doesn’t have to live in the same place on the user’s disk. Ideally, it should also be possible to export the regexp -> icon mapping as a regexp -> data URI mapping that can be imported into another profile.
+
Adding a few make steps to wrap this process would help everyone.
 +
This is a very easy project to tackle but very benefitial if the time and love is given to it.

== Tbeachball - Quantifying Mozilla's Responsiveness ==  
+
== Create a cross-repo pushlog to see all locales's checkins ==
 +
We currently check many different repositories to trigger builds when a developer makes a change. We also check the localizer's repositories to see if they have pushed any changes. The problem is that we have close to eighty different localization repositories and that takes a long time to check each one of them.
 +
If we had a joint view that would improve our systems. An example of that view is:
 +
https://l10n-stage-sj.mozilla.org/pushes/
 +
but the format should be more like this:
 +
http://hg.mozilla.org/mozilla-central/pushlog
 +
which is what our release engineering systems check for.
 +
This project would require you to hack hg and pushlog to make it work.
 +
armenzg has many blog posts explaining how to setup pushlog in your local machine.

This project will add instrumentation to Mozilla in order to determine how much time is spent away from the main event loop, and therefore from the user's mouse/keyboard input.  When the user does something, how long does it take for Mozilla to act on that stimulus?  One thing that sometimes interferes with interface responsiveness is spending too long away from the main event loop, perhaps in layout or some other intensive computation. This leads to new events from the user, such as mouse clicks or keypresses, not being noticed and acted upon.  This could also be expanded in order to include the triggering of log points and specific dialog openings, etc. with a view to understanding what the long-running events actually are.

== Thunderbird SMTP Auto-Sensing ==
  
−
== Mozilla Developer Virtual Appliance ==
+
Modify Thunderbird so that it uses the correct SMTP server for your current network and IP.  In other words, if you are at home, use your home ISP's SMTP, but if you use a school wireless network, switch to the school's SMTP.  These various SMTP configurations should be manually controlled by the user, that is, you don't have to try and figure out which SMTP to use.  Rather, it should be configurable in an options dialog.

== Add Multi-File transfer to distcc ==
+
Add the possibility to compact the database for local storage calendars based on SQLite using the VACUUM command. At the moment the local database for events and tasks will not get smaller even if you delete your tasks and events. This has serious performance implications for people, who work a lot with their calendar.
  
−
The recent work to add [[Distcc With MSVC|MSVC support]] to distcc only allows for a single file to be sent back from build slaves. This means that extra debugging info (e.g., .pdb files) cannot be sent with binaries.  Modify distcc so that it can support debug Mozilla builds.

== Add password managers for various platforms ==
+
== <strike>[[Spellcheck Extension for Arbitrary Web Pages]]</strike> ==
  
−
Previous work was done on adding [[OS X Keychain integration]] to Firefox.  This work was focused on tightly binding C++ and Mac API calls.  Since then more work has been done to [http://blog.mozilla.com/dolske/2007/05/28/followup-password-manager-changes-coming-in-ff3-alpha-5/ modularize the password manager] in Firefox.  Various platform "keychains" need to be integrated with the new system. See bugs [https://bugzilla.mozilla.org/show_bug.cgi?id=309807 309807], [https://bugzilla.mozilla.org/show_bug.cgi?id=106400 106400], and [https://bugzilla.mozilla.org/show_bug.cgi?id=371000 371000].

== Convert password storage to a SQLite database ==
+
== <strike>Modify Firefox to handle files downloaded to Temp more appropriately </strike>==
  
−
Currently, Firefox stores logins in a text file in the user's profile (signons2.txt). The format is simple, but inflexible. Storage of other browser data, such as cookies and form history, has steadily been moving towards using SQLite-backed databases so moving password storage to the same kind of storage would be good. Some work was started in [https://bugzilla.mozilla.org/show_bug.cgi?id=288040 bug 288040].
+
<strike>Often files downloaded by the browser are put in a temporary folder that is emptied on close.  Users (and especially novice users) should be protected from inadvertent data loss as a result of important files being saved to this temp folder.  This project will add fixes to the browser so that users are protected. Ideas include:
  
−
== Support for OpenID ==
+
* Make Firefox aware of common productivity file types (e.g., .doc, .pdf) and whitelist these types so they aren't deleted
 +
* Have office type files download automatically to a documents folder instead of temp
 +
* Firefox could check the timestamp of such files and delete them only if the timestamp is the same as when it was originally saved by the browser (i.e., has not been edited)
 +
* Warn the user on closing the browser that files are going to be removed
 +
* Assuming files still exist on start-up (see above), alert the user that these files are still there (similar to "New Session or Restart Existing?" dialog)
 +
* Have the browser pop-up a Save As dialog instead of automatically saving to temp, and use a documents path

[http://openid.net/ OpenID] is an open, decentralized, free framework for user-centric digital identity. It's built on existing web technologies so that it can work without special support in the browser. However, tighter browser integration could allow for increased security and easier management. See [https://bugzilla.mozilla.org/show_bug.cgi?id=356853 bug 356853]. Needs definition as to exactly what should be done and how. Could be initially implemented as an extension.
+
Other ideas are possible, and a combination of these might be necessary. Ultimately, this fix should target regular users without much knowledge of the filesystem.</strike>

== Refactor master password out of NSS ==
+
Resources: ted, mfinkle
  
−
Users can enable a "master password" in their browser, which securely encrypts all their stored passwords. The current implementation can be awkward to use and has some limitations, see [https://bugzilla.mozilla.org/show_bug.cgi?id=322617 bug 322617]. Fixing  this would involve having password manager being more involved with the cryptography operations -- deriving a key from a passphrase with PKCS#5, and using NSS and PKCS#11 to encrypt/decrypt entries.  
+

== Add Offline Support to an open source web app ==
+
== Standalone Test Harnesses ==
  
−
Firefox 3 will support offline abilities, such that web developers can write their apps so they work even when no network is present. Good headway has been made already [http://www.bluishcoder.co.nz/2007/02/offline-zimbra-with-firefox.html porting Zimbra].  Pick another web app and add offline support, for example: [http://moodle.org Moodle].
+
Mozilla uses several systems for [http://developer.mozilla.org/en/docs/Mozilla_automated_testing automated testing], including [http://developer.mozilla.org/en/docs/Mochitest Mochitest], [http://developer.mozilla.org/en/docs/Mozilla_automated_testing#Reftest Reftest], [http://developer.mozilla.org/en/docs/Writing_xpcshell-based_unit_tests xpcshell unit tests], and [http://developer.mozilla.org/en/docs/Mozilla_automated_testing#Crash_tests crash tests].  Currently, to run these test suites or develop new tests, you need to build your own Firefox with --enable-tests, and run the tests from the object directory.  Ideally there would be a standalone package available for download that would let you run these test suites against any Firefox build, to ease development of new tests and allow more people to get involved with automated testing.

== Add source checkout to buildbot ==
 +
 
 +
Unlike many open source projects, it's not possible to do a CVS checkout and build the code.  This is due to the complex module and version combinations necessary to get and build a particular product, for example Firefox.  To accomplish this, Mozilla uses [http://mxr.mozilla.org/seamonkey/source/client.mk client.mk], which provides a set of rules for getting and building the code.
 +
 
 +
Increasingly, Mozilla is moving toward using the Python based buildbot system for automated builds and tests.  It would be good to add a Source class for client.mk checkouts.  This would mean creating a a general Source class that understands the idea of checking out a file, and which could then be used to drive the checkout and allow for integration with client.mk.

== Port the Firefox Release Repackager to other platforms ==
 +
 
 +
The [http://benjamin.smedbergs.us/release-repackager/ Firefox Release Repackager] allows one to take a released version of the browser, deconstruct it in order to add some custom extension, then repackage it.  This allows organizations to ship slightly modified versions of stock releases, useful for their users.  Currently the repackager only works on Mac.
 +
 
 +
Port this tool to Windows and/or Linux.  In order to do this you'll need platform binaries of 7zip, or perhaps you can use P7zip to do a cross platform version.  There are other ideas that can be added to this tool as well for making it more flexible.

== gdb symbol server support ==
 +
 
 +
Microsoft's debugger allows the use of a symbol server, which it can use to download debugging symbols for programs and libraries.  [http://developer.mozilla.org/en/docs/Using_the_Mozilla_symbol_server Mozilla provides this] for nightly and release builds on Windows, and it's useful for people to debug their crashes locally without having to build a debug build.  This functionality doesn't exist for Linux or OS X, where gdb is the debugger.  gdb does support loading debug symbols from external files, so it could probably be extended to look for the symbols on a web server first.

== gdb support for minidumps for post-mortem debugging ==
 +
 
 +
Microsoft's debugger allows for loading a minidump produced during a crash and then performing post-mortem debugging. GDB supports using core files for the same purpose. In Firefox 3, we produce minidump files on all of our supported platforms for use with our Breakpad crash reporting system. Sometimes people may want to debug a crash locally using one of these minidumps. On Windows, using the symbol server, they can simply load the minidump in their debugger. Currently there is no equivalent on Linux or Mac. Extending gdb to support loading minidumps for post-mortem debugging would be useful. This project may rely on the gdb symbol server project to be truly useful.

== RegressionTry ==

 +
Make it possible to look for bugs across old nightly builds of Firefox using automated tools.  For example, [http://db48x.net/regression-search/ regression-search] is a script that allows you to do binary searches across binaries, looking for the existence of a bug.  This could be improved through the use of tools like [http://services.alphaworks.ibm.com/coscripter/browse/about co-scripter].  Ideally the user could look for bugs in automated ways, without having to download and install tons of browser versions.

The Talos performance testing system at Mozilla currently runs on a large set of web pages pulled from the Alexa Top 500.

−
== Make FUEL work with Firefox 2 ==
+
A useful solution to this problem would be a tool that takes a mirrored copy of a website and "sanitizes" it, by changing the page text and image contents (making them junk or filler text or something). The caveat here is that this *cannot* change the performance characteristics of the page. For example, taking a page that is all Chinese text and replacing it with "Lorem Ipsum" filler text would cause the page to take different text rendering paths, which would change what is measured. As another example, making all JPEG images solid black would likely make them decode and render much faster. Any solution should have some analysis performed that shows that performance is not significantly altered in the sanitized page set.

Introduction

This is a list of potential projects that need people.

Students: If you'd like to work on one of these, move the chosen project to the Project List and create a page for your work based on the Sample Project template.

Open Source Community Members: We welcome your recommendations for potential projects. Please create an account on this Wiki and create a description for your proposed project below. Please list your contact info (just an IRC or FAS2 name is OK) as well as links to any related web pages as Resources for the proposed project. (Questions? Ask Chris Tyler or David Humphrey).

SBR600 Potential Projects

Improve Localization build system

Currently it requires many many steps to produce another language of Firefox. It would really easy to package these many steps to reduce the required knowledge to generate a new language.

Adding a few make steps to wrap this process would help everyone. This is a very easy project to tackle but very benefitial if the time and love is given to it.

Reference: armenzg

Create a cross-repo pushlog to see all locales's checkins

We currently check many different repositories to trigger builds when a developer makes a change. We also check the localizer's repositories to see if they have pushed any changes. The problem is that we have close to eighty different localization repositories and that takes a long time to check each one of them. If we had a joint view that would improve our systems. An example of that view is: https://l10n-stage-sj.mozilla.org/pushes/ but the format should be more like this: http://hg.mozilla.org/mozilla-central/pushlog which is what our release engineering systems check for. This project would require you to hack hg and pushlog to make it work. armenzg has many blog posts explaining how to setup pushlog in your local machine.

Thunderbird SMTP Auto-Sensing

Modify Thunderbird so that it uses the correct SMTP server for your current network and IP. In other words, if you are at home, use your home ISP's SMTP, but if you use a school wireless network, switch to the school's SMTP. These various SMTP configurations should be manually controlled by the user, that is, you don't have to try and figure out which SMTP to use. Rather, it should be configurable in an options dialog.

'Compact databases' feature for Mozilla calendaring applications (Lightning, Sunbird)

Add the possibility to compact the database for local storage calendars based on SQLite using the VACUUM command. At the moment the local database for events and tasks will not get smaller even if you delete your tasks and events. This has serious performance implications for people, who work a lot with their calendar.

Spellcheck Extension for Arbitrary Web Pages

Write an extension to leverage the existing spellcheck code in Mozilla and add the ability to highlight spelling mistakes for a given web page (i.e., vs. a textbox).

Modify Firefox to handle files downloaded to Temp more appropriately

Often files downloaded by the browser are put in a temporary folder that is emptied on close. Users (and especially novice users) should be protected from inadvertent data loss as a result of important files being saved to this temp folder. This project will add fixes to the browser so that users are protected. Ideas include:

  • Make Firefox aware of common productivity file types (e.g., .doc, .pdf) and whitelist these types so they aren't deleted
  • Have office type files download automatically to a documents folder instead of temp
  • Firefox could check the timestamp of such files and delete them only if the timestamp is the same as when it was originally saved by the browser (i.e., has not been edited)
  • Warn the user on closing the browser that files are going to be removed
  • Assuming files still exist on start-up (see above), alert the user that these files are still there (similar to "New Session or Restart Existing?" dialog)
  • Have the browser pop-up a Save As dialog instead of automatically saving to temp, and use a documents path

Other ideas are possible, and a combination of these might be necessary. Ultimately, this fix should target regular users without much knowledge of the filesystem.

Standalone Test Harnesses

Mozilla uses several systems for automated testing, including Mochitest, Reftest, xpcshell unit tests, and crash tests. Currently, to run these test suites or develop new tests, you need to build your own Firefox with --enable-tests, and run the tests from the object directory. Ideally there would be a standalone package available for download that would let you run these test suites against any Firefox build, to ease development of new tests and allow more people to get involved with automated testing.

Add source checkout to buildbot

Unlike many open source projects, it's not possible to do a CVS checkout and build the code. This is due to the complex module and version combinations necessary to get and build a particular product, for example Firefox. To accomplish this, Mozilla uses client.mk, which provides a set of rules for getting and building the code.

Increasingly, Mozilla is moving toward using the Python based buildbot system for automated builds and tests. It would be good to add a Source class for client.mk checkouts. This would mean creating a a general Source class that understands the idea of checking out a file, and which could then be used to drive the checkout and allow for integration with client.mk.

Port the Firefox Release Repackager to other platforms

The Firefox Release Repackager allows one to take a released version of the browser, deconstruct it in order to add some custom extension, then repackage it. This allows organizations to ship slightly modified versions of stock releases, useful for their users. Currently the repackager only works on Mac.

Port this tool to Windows and/or Linux. In order to do this you'll need platform binaries of 7zip, or perhaps you can use P7zip to do a cross platform version. There are other ideas that can be added to this tool as well for making it more flexible.

gdb symbol server support

Microsoft's debugger allows the use of a symbol server, which it can use to download debugging symbols for programs and libraries. Mozilla provides this for nightly and release builds on Windows, and it's useful for people to debug their crashes locally without having to build a debug build. This functionality doesn't exist for Linux or OS X, where gdb is the debugger. gdb does support loading debug symbols from external files, so it could probably be extended to look for the symbols on a web server first.

gdb support for minidumps for post-mortem debugging

Microsoft's debugger allows for loading a minidump produced during a crash and then performing post-mortem debugging. GDB supports using core files for the same purpose. In Firefox 3, we produce minidump files on all of our supported platforms for use with our Breakpad crash reporting system. Sometimes people may want to debug a crash locally using one of these minidumps. On Windows, using the symbol server, they can simply load the minidump in their debugger. Currently there is no equivalent on Linux or Mac. Extending gdb to support loading minidumps for post-mortem debugging would be useful. This project may rely on the gdb symbol server project to be truly useful.

RegressionTry

Make it possible to look for bugs across old nightly builds of Firefox using automated tools. For example, regression-search is a script that allows you to do binary searches across binaries, looking for the existence of a bug. This could be improved through the use of tools like co-scripter. Ideally the user could look for bugs in automated ways, without having to download and install tons of browser versions.

Extend Try Server to test Thunderbird patches

"Specifically, Mozilla has a great system called “try servers” where one can submit patches against the tree, and the build system runs builds on Linux, Mac and Windows, using those patches, then serves those builds for testing. This is really helpful to figure out if proposed patches solve specific problems...The only problem is that there’s a little bit of patching needed to the try server code itself to make it able to work with other targets besides Firefox, as described in bug 431375" (Ascher)

Add DTrace probes and scripts for Mozilla code base

DTrace was created by Sun in OpenSolaris to allow developers to write simple scripts in order to probe and instrument executing programs in a way not possible otherwise. One of the advantages of DTrace is that it allows you to turn on probing when you need it, but not incur an execution penalty with regard to performance (i.e., when probes aren't being scripted, they aren't run). This requires developers to add "probes" to their source code.

This would involve creating a plugin or set of plugins and some html/js to drive that plugin in order to push test coverage. Maybe look at the JRE tests, create some specific plugin cases (e.g., swf to load that tests flash specific code). The newly announced Google Chromium browser seems to have something like this with regard to using the npapi for driving tests via plug-in. See also docs on IPC and plug-in design in Chromium.

This will require C programming, as well as light web development (html, js, perhaps swf).
