Project Update

June 4, 2018

If one was not following the mailing lists it might seem the Squid project has gone the way of the Dodo. In truth it is quite the opposite. The dev team and Foundation board are working so hard it has been difficult to find time for these additional updates.

 

So to recap the major projects going on since last update;

The largest change has been our move to git for source code repository. That has been a long road taking up a lot of time over several years. A great big thanks to the various people working on that.

Following along from that we now have github (squid-cache account) as our code repository for public access. The Squid Projects repository is no longer directly available for general access. Our code submission process has changed from accepting .patch files to github PR requests. So developers working on code changes please convert to that (I can still work with patch submissions, but it is significantly more trouble than having your own github account for submission updates/edits). Anyone who forked one of the Squid github repositories prior to the 2017 transition should fork the new repository and convert their code changes.

 

The new code submission process has resolved quite a few issues we had with the old submit and auditing/QA process. There are still a few quirky behaviours caused by github and our automation that cause trouble from time to time – but overall it is a big improvement on what we had before.

The largest issue we face now for QA and code development is manpower. We now have automated change tracking, content integration helping out with QA and a committer bot taking a huge load off my shoulders as maintainer. Our submission process is open and public – so anyone can read the proposals and should also be able to comment about any bugs you can see that have not already been pointed out. Anyone with an interest in the Squid code is encouraged to participate in that process.

 

In the shadow of all those very time consuming alterations to the Squid Project systems the dev team has also managed to iron out several of the major bugs blocking Squid-4 release. Just one of the long-standing bugs remain. A few regressions in recent code have brought up some new major bugs, but those are for the most part already fixed or soon will be. So watch this space for news on further progress there.

Whats going on with Squid 4

July 1, 2016

Those that have been paying attention will have noticed that Squid-4 beta cycle has been going on for a very, very long time. A whole year now in fact. There are several reasons for this.

* The ecosystem that Squid is deployed into has a somewhat mixed situation in regards to C++11.

Even 5 years after it was standardized compiler support is still not readily available in some popular OS distributions. In particular there are a large number of people clinging to the outdated but still supported RHEL 6 and its derived family of OS which do not easily provide recent versions of GCC. So we are procrastinating on the deprecation of Squid-3.5 to give more people a chance to move on. The clock is ticking though.

* We had a lack of early adopters testing the early versions of Squid-4.

So bugs that only show up in real usage have been very slow to be found. We don’t make a new version start its beta cycle until the developers are reasonably sure that its stable enough to be used. The beta process is supposed to be just a confirmaton of that. Indeed a year ago 4.x looked like it had no bugs at all. Which is kind of suspicious, but not impossible. As the betas progressed though the bug reports started rolling in. It is somewhat a testament to how our modern build systems are catching out minor and trivial bugs that these tester reported issues have largely all been difficult to resolve.

* We are experimenting with a new management process for Squid releases.

Previously Squid-5 would have been branched for development and Squid-4 starting to stagnate, er, become “stable”. This time though we have delayed the branching and instead kept Squid-4 as main development branch for minor changes while the beta cycle goes on. That has made it a little more volatile than most of the Squid-3 series betas.

All up, we are down to the last few major bugs to be resolved in the new code. Progress on those is slow but steady. So Squid-4 production “stable” release should be not to far ahead on the calendar.
