Re: better changeset tracking

Ouf... Wez and I may have different ideas here, but we were both aiming to keep it simple. That's because we both know that if it turns into a big job/makes life more complicated for the dev team, nobody will find the time or inclination to implement it anyway! Switching to subversion would mean a learning curve for some, and a change of PHP development tools and practice for _everyone_ involved in php.net. It's a major step, particularly at a time when people are finding themselves stretched anyway (the starting point of this entire issue). Besides, the whole issue of PECL branch, commit and bug reporting mechanisms needs some serious thought beforehand, because there are so many niggling problems there. It'd be better to resolve those problems (at least in a theoretical sense) before the move than after. So yeah - a huge job, and not only from the repository admin perspective. - Steph ----- Original Message ----- From: "Andi Gutmans" <andi@zend.com> To: "Rasmus Lerdorf" <rasmus@lerdorf.com> Cc: "Wez Furlong" <kingwez@gmail.com>; "Ilia Alshanetsky" <ilia@prohost.org>; "Edin Kadribasic" <edin@krug.dk>; "PHP Internals List" <internals@lists.php.net> Sent: Wednesday, May 30, 2007 6:18 AM Subject: RE: [PHP-DEV] better changeset tracking Well I think Subversion the way it is today is already considerably better. Just the directory versioning and the better performance would already pay off in the PHP project. No doubt that merge tracking is an added bonus but it's not exactly applicable (yet) to the way we work in the project as we are mainly doing selective merges. It would require us to somewhat rethink how we want people to develop (i.e. branch per major feature, branch per mini release, etc...). Btw, I didn't recommend it because of changset tracking, but rather if we make significant changes to our dev infrastructure we might as well build it on the right foundations and moving to SVN will be inevitable at some point. I think it already provides enough value today to start considering it. Andi

The only advantage pre-1.5 is slightly better support for other tools that sit on top of it, but even there it isn't a clear win. There are changeset trackers for CVS as well that would be a lot easier to add on to our current infrastructure than switching the entire thing to svn first. Once Subversion 1.5 comes out (which isn't that far off), the landscape finally changes and assuming that it works, we'll finally have a real technological incentive to move. -Rasmus Andi Gutmans wrote: In general I think we should consider upgrading part of our infrastructure. The only problem is that it takes a lot of time, energy and devotion. And of course people need to be willing to get used to the new way of doing things. Foremost I think we could benefit from moving to SVN. We've had very good experiences with it and I think it fixes a lot of CVS shortcomings. The move would of course be quite an undertaking with years and years of history (and added/removed files). The Zend Framework project is an example of an open-source project where we have a more strict dev process. We open bugs for everything using JIRA (unfortunately Java-based but pretty powerful and integrates nicely with SVN so that changesets are connected to the bugs), it also allows us to easily see status of where we are for the release, and there are some nice perks like being able to auto-generate a list of bug fixes for a given version (http://framework.zend.com/issues/secure/Dashboard.jspa). There are also quite a few other benefits but just by browsing around a db in action some of those benefits should be visible. Starting to look at this stuff would take a lot of effort though and not sure if there are enough able people willing to step up to the plate. I think starting with a move to SVN would probably be best because a lot of other apps integrate/depend on it. Andi

I also recognize that we need to find a way to guarantee

that patches

don't slip through the cracks and don't get lost. I think we could do with investing a little bit of time

into finding

a way to automatically review commits to see if they have

been merged

to all relevant branches. For this to be viable, we should probably adopt the practice of explicitly referencing a bug number in all commits (could be enforced by the commit hook); we can

then analyze

the commit messages to make sure that commits referencing a particular bug number have a corresponding set of commits in the branches, and vice versa. Once we have that data, we could have job that periodically (daily) reviews the activity per bug report and sends an email reminder about reports that have missing merge activity for longer than a week. --Wez. PS: We could also consider posting links to commit URLs to the associated bug report; this is a feature I really value in our subversion/trac repositories at OmniTI.

Unfortunately I don't have as much time to spend on PHP

making commits

that may break the builds or spending hours resolving conflicts I focus my attention on PHP5 where fixes and improvements
