I would like to upgrade Apache Traffic Server (ATS) from v3.0.x to new stable branch v3.2.x. The 3.2 branch has lots of improvements for IPv6 and SSL that are important to me, and also fixes a crash I've been hitting in v3.0. But, unfortunately there are a couple of incompatible config file changes, ref: https://cwiki.apache.org/confluence/display/TS/Upgrading+to+3.2 Only the "SSL certificate configuration" and "HTTP Quick filtering configuration" needs to be handled by the user (if they are used). The hostdb and stats-changes can be handled automatically during upgrade. So, IMHO the incompatibilities are very small, and I believe the userbase is also quite small. Hopefully I should be able to reach most users trough the trafficserver-devel and users mailinglist. Looking trough the exceptions lists on http://fedoraproject.org/wiki/Updates_Policy#Stable_Releases: Things that would make it more likely to grant a request: * The package is a "leaf" node. Nothing depends on it or requires it. [Applies] * The update fixes a security issue that would affect a large number of users. [No] * The update doesn't change ABI/API and nothing needs to be rebuilt against the new version [Applies] * The update fixes serious bugs that many fedora users are encountering [Applies, fixes segfault] Things that would make it less likely to grant a request: * The update converts databases or resources one way to a new format. [internal cache files only] * The update requires admin intervention for the service to keep working (config file format changes, etc). [Maybe -- if the two relevant features are in use] * The update causes behavior changes (something that was denied is allowed, etc) [No] * The update changes the UI the end user sees (moves menus or buttons around, changes option names on command line) [No] * The update fixes bugs that no fedora user has reported nor would affect many fedora users (ie, fixes for other platforms or configurations). [No, I've personally hit crashes on EPEL and expect the same crash should happen on Fedora] Will it be OK to do this upgrade in F15/F16/F17, or are we stuck on v3.0 ? Highlights of this release includes: * Over 800 commits, and 300 Jira tickets closed since v3.0. * Several SSL improvements, including SNI (Server Name Indication) and NPN (Next Protocol Negotiation). Overall SSL stability is also improved. * Full IPv6 support, v3.0 only had client side IPv6. All IP related plugin APIs are now also IPv6 aware. * New, flexible configurations for managing inbound and outgoing IP addresses and ports. You can now bind any number, and combinations, of addresses and ports for both HTTP and HTTPS. * Range request for large objects in cache are now much (much) faster. * Several new, and improved, plugin APIs are now available. * Performance and stability improvements in the Cluster Cache feature. * Much better performance when proxying to a Keep-Alive HTTP backend server connection. Overall cache performance is also significantly better. * Several stable plugins are now included with the core distributions. * Supports all gcc versions 4.1.2 and higher, Clang / LLVM 3, and the Intel compiler suite. Builds and runs on Linux, FreeBSD, Solaris and OSX. -jf -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
