Line 13: Line 15:
As we develop new ideas for features in Ubuntu, it's important to be able to communicate them clearly. This serves the purpose of making it clear what the feature is about, and allowing people to evolve an implementation strategy for it.

Publishing this content gives our community a chance to participate in the discussion and design of a feature, and increases the chance that community members will feel confident enough to start work on the implementation of the feature.

A good specification also allows community members who were not physically present at meetings discussing a topic to participate in the implementation of the spec.

Bottom line: the better your spec, the better the chances that your ideas will be clearly understood by the review team.

  * Bob is the maintainer for the boot process for Ubuntu. In the Dapper cycle, he would like to work on getting the boot time down to two seconds from boot manager to GDM screen. He creates an entry for the specification in Launchpad, proposes it for the UBZ sprint, and starts writing out a braindump of it in the Ubuntu wiki. Magnus, who is in charge of UBZ scheduling, thinks it sounds fishy but approves it to make sure that the change is discussed and documented properly. He marks it as priority Medium because he isn't sure Bob will have time free for implementing it during Dapper.   * Bob application crashed. He has no idea how much time it would require for the uploading of crash to complete. Hence decisions (if his work is interrupted or finishe) such as shutting down the machine, or going to hibernate or keep the machine running for the upload to finish for some time are unknown.
Line 25: Line 20:
  * Pedro works on Malone, in Launchpad. Before UBZ, he remembers that the dependency handling in the bug tracker is really not optimal. He writes out a Summary and Rationale in a Launchpad wiki page, registers it as a specification in Launchpad, and suggests it for UBZ. Monica, Launchpad manageress, thinks that this is really not the time to be talking about it and rejects the application for UBZ. He then indicates it for the next conference, UBB, and marks its priority is Low.   * Peter application crashes. He thinks apport would report it. During the upload for some reason or the other, network connection lost, power cut-out etc, he is unable to upload the crash file. The crash file remains in /var/crash & is not useful for anybody.
Line 27: Line 22:
  * Jason is an Ubuntu and Rosetta user. He has noticed that changes made to translations are making their way into language packs but not to the upstream versions, and adds a specification that describes a way for getting upstream to use language packs. Monica also has a plan for this but hadn't described it in a spec, so she adds it to the UBZ spec list, and adds Carlos, Rosetta maintainer, as drafter for it.   * Jason is working in a bank/clinic/finance instituion. He was making an e-commerce transaction through some application (for e.g. firefox) and the application crashed. He is in 2 minds whether to send the crash or not.

  * If you don't know enough to be able to competently write a spec, you should either get help or research the problem further. Avoid spending time making up a solution: base yourself on your peers' opinions and prior work.

The summary should not attempt to say '''why''' the spec is being defined, just '''what''' is being specified.

=== Rationale ===

This should be the description of '''why''' this spec is being defined.

=== Scope and Use Cases ===

While not always required, but in many cases they bring much better clarity to the scope and scale of the specification than could be obtained by talking in abstract terms.		    *Logs
     *The apport log should also have error messages as to why a certain report could not be sent. If user has turned off apport it should be mentioned.
Line 61: Line 50:
This section is usually broken down into subsections, such as the packages being affected, data and system migration where necessary, user interface requirements and pictures (photographs of drawings on paper work well).  As of right now, I know it would be affecting apport-gtk.
Line 65: Line 55:
To implement a specification, the assignee should observe the use cases carefully, and follow the design specified. He should make note of places in which he has strayed from the design section, adding rationale describing why this happened. This is important so that next iterations of this specification (and new specifications that touch upon this subject) can use the specification as a reference.
Line 67: Line 56:
The implementation is very dependent on the type of feature to be implemented. Refer to the team leader for further suggestions and guidance on this topic.

Line 71: Line 62:
The specification process requires experienced people to drive it. More documentation on the process should be produced.
Line 73: Line 63:
The drafting of a specification requires English skills and a very good understanding of the problem. It must also describe things to an extent that someone else could implement. This is a difficult set of conditions to ensure throughout all the specifications added.

There is a lot of difficulty in gardening obsolete, unwanted and abandoned specifications in the Wiki.

Summary

Add privacy, resumability and ftp features (with an ETA & upload speeds) to apport. This will allow apport to be used more effectively. One can bank on apport to report all crashes without the user being interfered or being paranoid.

Rationale

  • As of right now, one is never sure if apport has uploaded the bug or not. Also there are concerns regarding security, for e.g. if firefox crashed or some application which has properties such as names,passwords, (in case of firefox or other browsers) websites gone (profiling) etc. This needs to be communicated to the user. In essence apport has to be intuitive.

Use Cases

  • Bob application crashed. He has no idea how much time it would require for the uploading of crash to complete. Hence decisions (if his work is interrupted or finishe) such as shutting down the machine, or going to hibernate or keep the machine running for the upload to finish for some time are unknown.

  • Peter application crashes. He thinks apport would report it. During the upload for some reason or the other, network connection lost, power cut-out etc, he is unable to upload the crash file. The crash file remains in /var/crash & is not useful for anybody.

  • Jason is working in a bank/clinic/finance instituion. He was making an e-commerce transaction through some application (for e.g. firefox) and the application crashed. He is in 2 minds whether to send the crash or not.

  • shirish tries to upload a crash file. After waiting for about an hr. He gets a message saying HTTP Error 500: Internal Server Error. [https://bugs.launchpad.net/ubuntu/+source/apport/+bug/99989]

Scope

Any user using apport (Ubuntu Feisty) & above perhaps.

Design

Big Picture

  • This will allow apport to be a more robust application.
  • FTP features
    • This will allow apport to show an an upload bar with an ETC for bugs. Similar to how its done at rapidshare.com or any other public upload site.
  • Resumability
    • This will make sure /var/crash remains empty at all times. If possible send crashes when network activity is at the lowest.
    • Messages
      • Give user error messages otherwise remain in background. If the user wants a verbose mode then show him all the goodies.
      • Logs
        • The apport log should also have error messages as to why a certain report could not be sent. If user has turned off apport it should be mentioned.

Implementation Plan

  • As of right now, I know it would be affecting apport-gtk.
