Taking the plunge...

Sat Dec 3 17:48:23 CST 2011

Hi Johan, currently yes we do use it but not really in its fullest i.e. SmartObjects. Our app is actually webspeed but we use a third party product (Sandersons EOrganiser framework) which takes html pages we write in a standard html editor,and generates the webspeed for us into an include. We then referencce this along with some other core framework includes into a progress container object which maps to the two objects together. The framework then pulls it altogether at runtime. 

We're currently going through a slow upgrade to OE10 which should be done in the next few months so then we will be on Architect. 

Are you using Progress with Mercurial then?

Steve

Steve,
Are you using the Progress AppBuilder for the GUI ?

	Hi, I am looking into migrating my development teams over to the wonders of Mercurial, but have many questions running through my head about how to achieve this, or even whether Mercurial is the right tool.

	We are a Progress development house (www.progress.com for those who haven't heard of Progress......probably everyone!), and currently use a vendor sourced SCM called Roundtable. Roundtable is written in, and promoted by Progress so that is why we have it.  It also comes in at about £2k per developer, plus an annual maintenance/support package.  It is very rigid, and very strict, but to be fair has served us well.  However massive growth and cent offshoring/cosourcing of development has meant we need to start looking down a different path......thus Mercurial.

	I have done a lot of reading,and a lot of investigation around a variety of tools, and in fact in my distant past I was a user of SVN, so some of the concepts of Mercurial aren't new to me.  Recently I have focused my research into GIT and Mercurial, and for, in part, political reasons, Mercurial has now been thrust to the top of the list.

	My first task really was to work out a suitable SCM strategy, and supporting developer/release work flows.  I stumbled across a very good article on this very idea, which although focused on GIT, the concepts are perfect for how we work, and from the posts on that article this can work with Mercurial too.  My problem is I can't visualise how exactly, day to day, Mercurial fits into this strategy.  The article is here http://nvie.com/posts/a-successful-git-branching-model/

	My question(s) really is, how would one go about working with a strategy like this?  Where this article refers to branching (feature branch, release branch etc) would they be clones in Mercurial land?? 

	Of course that strategy there may not be the best approach, so if anyone can point me to some better examples of Mercurial usage that would be great.  We currently have around 30 developers, some based in the same office, some offshore and some offsite.  Our code base is some 10,0000 files amounting to about 1gig at a guess.  It's worth mentioning too that this application serves 6 businesses in effect.  Each business is an internationals variant or like a franchise of our uk business.  As a result we have currently a single core codebase, and this then feeds into 6 sub code bases.  The main reason for this is economy of scale for our sub businesses, and it gives us the ability to feed functionality etc developed for one business out to our others.  So our code base currently looks a little like this hierarchically :

	Level 1 : Dev
	Level 2 : TestSpain TestFrance TestUSA TestItaly
	Level 3 : ProdSpain ProdFrance ProdUSA ProdItaly

	So dev feeds into 6, and then each of those feeds into the appropriate Prod.  Then within the code itself we have switches etc to say "IF Business is France THEN DO....".  Not white that crude, but you get the idea.

	Anyway, that's a bit of brain dump, so apologies but I wanted to sort of put that out there in the hope that I can prompt some Mercurial gods to see it and go "hey that's easy,  you need to do this....", or at least say "nah, you should go and read this before posting that on here"

	Many thanks for at least reading all that and getting this far down before deleting!

	Steve
