Testing Mozilla Linux/Runtime Requirements

Project Description

Mozilla is in the process of finalizing a set of Linux library and runtime requirements for distributions wanting to ship Mozilla software. This project will test various bugs against two different sets of runtime setups, hoping to expose any issues with the new requirements.

Project Details

Testing of the current (RHEL5) and proposed runtime setups will be done using VMs on Hera. The initial list of bugs for testing against is available here.

All bugs will be tested on the two reference runtimes, and information about each bug's behaviour will be recorded (e.g., fixed/improved/changed with the new ref platform). Bugs that are resolved by the new reference VM will be marked WORKSFORME, as requested by Mike Connor. The rest of the bugs will have a comment added, indicating that the bug is still present on modern platforms.

For testing purposes, the most recent alpha will be used, currently alpha 5.

Two Reference Runtimes

1.CentOS 5

2.Fedora 3

WORKFORME (Fedora and CentOS) means bug has been fixed for both.

NOT FIXED - Bug has not been fixed.

NEEDINFO (Fedora and CentOS)- Need more information to reproduce the bug.

Some bugs has different results for both fedora and CentOS and links for both of them are given below:
