== Benefit to Fedora ==
== Packages in the Platform ==
<!-- What is the benefit to the platform?  If this is a major capability update, what has changed?  If this is a new functionality, what capabilities does it bring? Why will Fedora become a better distribution or project because of this proposal?-->


== Scope ==
<!-- The platform that the SCL is creating is implemented by a set of rpm packages.  There may be additional packages in Fedora that are built for the SCL but are not part of the platform. This section of the SCL Definition makes it clear to end users what packages are part of the platform so they do not have false expectations.  -->
<!-- What work do the developers have to accomplish to complete the change in time for release? Is it a large change affecting many parts of the distribution or is it a very isolated change? What are those changes?-->


* Proposal owners:
The following packages are part of the platform that this SCL implements.  Packages which are built for the SCL but not mentioned here are not part of the platform and may be removed or changed in incompatible ways according to normal Fedora Policies (Usually, when a new release of Fedora is made).
<!-- What work do the feature owners have to accomplish to complete the feature in time for release?  Is it a large change affecting many parts of the distribution or is it a very isolated change? What are those changes?-->

=== Compatibility Guarantees ===
<!-- Does this feature require coordination with release engineering (e.g. changes to installer image generation or update package delivery)?  Is a mass rebuid required?  If a rel-eng ticket exists, add a link here.  -->


* Policies and guidelines: N/A (not a System Wide Change) <!-- REQUIRED FOR SYSTEM WIDE CHANGES -->
The packages in an SCL's platform are often more concerned with maintaining backwards compatibility than other packages in Fedora as SCLs exist to provide you with a more stable platform to build your own cross-platform software.  As such, many of the packages in the SCL have specific compatibility guarantees. This section defines which packages in this SCL have more strict backwards compatibility guarantees and what those guarantees are so that you know what to expect.
<!-- Do the packaging guidelines or other documents need to be updated for this feature?  If so, does it need to happen before or after the implementation is done?  If a FPC ticket exists, add a link here. -->
 
== Upgrade/compatibility impact ==
<!-- What happens to systems that have had a previous versions of Fedora installed and are updated to the version containing this change? Will anything require manual configuration or data migration? Will any existing functionality be no longer supported? -->
 
<!-- REQUIRED FOR SYSTEM WIDE CHANGES -->
N/A (not a System Wide Change)
 
== How To Test ==
<!-- This does not need to be a full-fledged document. Describe the dimensions of tests that this change implementation is expected to pass when it is done.  If it needs to be tested with different hardware or software configurations, indicate them.  The more specific you can be, the better the community testing can be.  
 
Remember that you are writing this how to for interested testers to use to check out your change implementation - documenting what you do for testing is OK, but it's much better to document what *I* can do to test your change.
 
A good "how to test" should answer these four questions:
 
0. What special hardware / data / etc. is needed (if any)?
1. How do I prepare my system to test this change? What packages
need to be installed, config files edited, etc.?
2. What specific actions do I perform to check that the change is
working like it's supposed to?
3. What are the expected results of those actions?

<!-- The release notes also help users know how to deal with platform changes such as ABIs/APIs, configuration or data file formats, or upgrade concerns.  If there are any such changes involved in this change, indicate them here.  A link to upstream documentation will often satisfy this need.  This information forms the basis of the release notes edited by the documentation team and shipped with the release.


Release Notes are not required for initial draft of the Change Proposal but has to be completed by the Change Freeze.  
* Had to change the behaviour of url.get() when retrieving https sites due to security risk.  This function now fails if the server's certificates are invalid or cannot be verified.  An optional parameter, allow_broken, can restore the former behaviour if you are willing to assume the security risk.
* The db library code was updated because upstream no longer supports the old library and the old code had too many security flaws.  The new version has an incompatible file format.  We ship a script /usr/bin/convert_db that can convert from the old format to the new one but it must be run on each db file before the library can read it.  It's beyond the scope of this SCL to determine what an application chooses to do if it encounters a db file it doesn't know what to do with so there's the chance that an application may choose to overwrite old db files instead of letting you upgrade them.  Please take backups.

Comments and Explanations
The page source contains comments providing guidance to fill out each section. They are invisible when viewing this page. To read it, choose the "edit" link.
Copy the source to a new page before making changes! DO NOT EDIT THIS TEMPLATE FOR YOUR SCL REQUEST.


Warning.png
This page is a draft only
It is still under construction and content may change. Do not rely on the information on this page. This is a draft SCL Definition. It needs to be approved by the FPC before an SCL following this draft can be created. The FPC uses the criteria on https://fedoraproject.org/wiki/User:Toshio/SCL_Guidelines_(draft)#SCL_Criteria to evaluate whether the SCL is okay for Fedora.

Summary

Maintainers

Detailed Description

Packages in the Platform

The following packages are part of the platform that this SCL implements. Packages which are built for the SCL but not mentioned here are not part of the platform and may be removed or changed in incompatible ways according to normal Fedora Policies (Usually, when a new release of Fedora is made).

  • <package name>
  • <package2 name>

Compatibility Guarantees

The packages in an SCL's platform are often more concerned with maintaining backwards compatibility than other packages in Fedora as SCLs exist to provide you with a more stable platform to build your own cross-platform software. As such, many of the packages in the SCL have specific compatibility guarantees. This section defines which packages in this SCL have more strict backwards compatibility guarantees and what those guarantees are so that you know what to expect.

Warning.png
Security trumps compatibility
If a security issue needs to be fixed but that breaks backwards compatibility, the security issue will be fixed despite violating the guarantee. This page will be updated to mention the Fedora versions and the version of the relevant packages from the SCL which needed a backwards incompatible change to fix the issue).
Warning.png
Guarantees are only best effort
SCL maintainers attempt to keep these backwards compatibility guarantees but the guarantees are not set in stone. As an example, the guarantees could be changed if the maintainer of an SCL decides to orphan it and someone new takes over. The new maintainer may decide to guarantee backwards compatibility for a smaller set of packages or make incompatible updates to some of the existing packages. These types of changes can only occur between Fedora releases.
