Chapter 19: Using template_product to Build and Distribute UPS Products

In this chapter we describe the template_product product, and show how to use it to build and distribute a product.

19.1 Overview

To simplify and somewhat automate the process of building UPS products, we have designed the product template_product. Once this product is installed on your system, it can be cloned into a new product area and "turned into" the new product. template_product can be used to build products of all types (shell script, pre-built binary, source code).

The following is a summary of the steps involved when using template_product to build a UPS-compatible product. Each step is described in detail later in this chapter:

  1. Make sure template_product is installed on your system; install it if necessary
  2. Setup template_product
  3. Create a directory for your product
  4. Clone template_product to create a template for your product in the new directory
  5. Insert the product into the template
  6. Setup and test the product
  7. Distribute the product (using the Makefile provided with template_product)

Also discussed in this chapter are:

19.2 Accessing template_product

The template_product product may already be installed on your system. If not, download it from the distribution node and install it into the main products area on your system by using the usual installation commands:

% setup upd 
% upd install template_product 

19.3 Cloning template_product

Next you need to setup template_product, make a directory to hold your new product, and clone template_product into this new area using a script that comes with it called CloneTemplate. You need to provide the name and version of your product to this script (we use newprod v1_0 in this example). Enter this sequence of commands:

% setup template_product 
% mkdir /tmp/newprod 
% cd /tmp/newprod 
% CloneTemplate 
Product name? newprod 
Product version? 1.0 
Platform specific product [yN]? y 
Dependant products [list as fred:joe:harry]? 
installing template product files in /tmp/newprod 
42 blocks 
Customizing product as newprod... 
# for Flavored products 
 for NULL products 
 for NULL products 
#   QUALS is added qualifiers, like: "QUALS=mips3:debug" 
# for Flavored products 
# for NULL products 
#          QUALS="" 
## Files to include in Distribution 

The files listed in the command output have now been copied into the new product directory, and Makefile and ups/template_product.table have been customized/renamed for the product. Note that the output shows the full pathname to the created files even though you are working from within this new product directory.

19.4 The Top-Level Makefile

The cloning of template_product creates a Makefile in the new product's root directory, e.g., /tmp/newprod/Makefile. In order for this Makefile to know what it needs to about the new product, you generally need to make a few changes to the top page or so, e.g., change the flavor, add build instructions, and so on. Changes of this type are discussed in section 19.6.3 Add Build Instructions to Top-Level Makefile. You can also add commands to other targets.

The first part of the file is reproduced here for reference (comments not shown):

all: proddir_is_set build_prefix 
        rm -f $(PREFIX)  
test: proddir_is_set clean FORCE 
        sh test/TestScript 

19.5 Inserting your Product into the Template

Now you need to add your actual program into the template_product clone, and run build instructions, if any. For shell scripts and pre-built binaries, all you need to do is create a bin directory under the product root, and put the executable in it. For source code, you need to first create a src directory under the product root, put the source file in it, and then build the product as described in the next section, 19.6 Building the Product.

19.6 Building the Product

19.6.1 Add Build Instructions

We recommend that you create a Makefile (separate from the one provided) to ensure reproducibility of the build procedure. Create or copy the Makefile in the src directory, and include a build target, e.g., install, as shown (again, we use echo to create the file since it's very simple for this example):

% echo "install:; cp hello ../bin" > Makefile 

19.6.2 Run the Initial Build

Now create the bin directory under the product root, and run make to complete the build:

% mkdir ../bin  
% make hello install 
cc    -o hello hello.c  
cp hello ../bin 

19.6.3 Add Build Instructions to Top-Level Makefile

Now it's time to customize the top-level Makefile created by CloneTemplate (refer to section 19.4 The Top-Level Makefile for a partial file listing). Typical macro definitions that need to be changed for a compiled program are:


Next, add the build instructions under the all target. For this example, they are the two commands that were just run (mkdir and make).

all: proddir_is_set build_prefix  
        -mkdir bin 
        cd src; make hello install 

19.6.4 Rebuild Instructions

The next time this product requires a build, you would just run the command:

% make [all] 

from the product root directory.

19.7 Testing your Product

Now you can setup and test your product. As an example, for our product we might run:

% setup newprod v1_0 -r $cwd -M ups -m newprod.table 

or, for Bourne shell,

$ setup newprod v1_0 -r `pwd` -M ups -m newprod.table 

followed by:

% hello 
hello world 
% unsetup newprod v1_0 
% hello 
sh: hello: command not found 

After testing, edit the test/TestScript file so that it tests your software. In many cases, writing a good test script can be rather challenging. Include at least a basic test to ensure that the product works properly. For our example, the test script just needs to run our hello program and verify its output, e.g.,:

hello | grep "hello world" > /dev/null 

This will exit with a successful exit code if hello prints hello world, and fail otherwise.

19.8 Customizing your Tar File

Products generally get distributed as tar files. The template_product top-level Makefile can be used to make a product tar file and add it to the distribution node in one step. There are several variables in the Makefile that control what template_product includes in the tar file it makes of a product:

lists directories whose non-CVS-bookkeeping-files should be added. The default is for this to be set to ".", the current directory, and the other variables left blank. If you only wanted to include the bin and lib directories of your product build area, you would specify ADDIRS=bin lib.
lists file wildcards to include or exclude with find(1) options. E.g., to exclude files ending in tilde (i.e., emacs backup files), specify ADDFILES= ! -name '*~'.
lists empty directories to include in the product tar file. By default the tar command does not include empty directories in a tar file. Listing empty directories here causes them to be added.
specifies a command that generates a list of files on standard output. These files will then be included in the tar file. This could be used, for example, to use an explicit file inclusion list like ADDCMD="cat my_file_list".
Or it could be used to specify a find command with filtering, sorting, and so on, e.g.,
ADDCMD= "find . ! -name '*.o' | egrep -v \ '/foo/|/bar/' | sort -u"

These values are all combined by running the following sequence of commands in the Makefile:

    for d in  .manifest.$(PROD) $(ADDEMPTY); do echo $d; done 
    test -z "$(ADDDIRS)" || find $(ADDDIRS) $(PRUNECVS) ! -type d -print 
    test -z "$(ADDFILES)" || find . $(PRUNECVS) $(ADDFILES) ! -type d -print 
    test -z "$(ADDCMD)" || sh -c "$(ADDCMD)" 

(where PRUNECVS holds find options to prevent find from going into CVS directories). This generates a long list of files that get added to the tar file.

19.9 Adding your Product to a Distribution Node

The Makefile for template_product is set up to allow distribution to fnkits by default:

To add a product to a different distribution node (e.g.,

19.9.1 Add Product to fnkits

Keeping the defaults in place, simply change to the directory of your product and run make kits:

% cd /tmp/newprod 
% make kits 
rm -f /tmp/build-newprod-v1_0    
creating .manifest... 
creating /tmp/newprod/../newprodSunOS+5v1_0.tar...

 -M /ftp/upsdb/newprod -m v1_0.table 
rm -f "/tmp/newprod/../newprodSunOS+5v1_0.tar" 

After adding your product, use upd list to check that it arrived properly:

% upd list -a newprod 
        Product=newprod Version=v1_0    Flavor=SunOS+5 
                Qualifiers=""   Chain="" 

19.9.2 Specify Multiple Flavors

To add different flavors of the same product without having to modify the Makefile, you may find it convenient to specify the flavor on the make command line, e.g.,

% make "FLAVOR=SunOS+5" kits 

or, more generally,

% make "FLAVOR=${UPS_FLAVOR}" kits 

19.10 Adding your Product Source to a CVS Repository

At this point, your product is eligible for inclusion in one of Fermilab's CVS repositories. This allows tracking of the software revisions, and allows other people to find it, get a particular version, and build it if they need to. The eligibility standards are described in the document Using Fermilab CVS Product Source Repositories, at

First set up CVS appropriately for the repository you're going to use (the example shows fermilab), then import your product:

% cvs import newprod v1_0 fermilab 

19.11 Removing your Product from a Distribution Node

A special target is provided in the top-level Makefile to remove a product from KITS, namely:

unkits: delproduct 

To remove your product from the KITS database on the fnkits node, just run the command:

% make unkits 
upd delproduct -h fnkits -f SunOS+5  newprod v1_0 
upderr::upderr_syslog - successful ups undeclare newprod v1_0 -f SunOS+5 

If your product is on a distribution node other than fnkits, the Makefile has probably already been edited to recognize that node (see section 19.9 Adding your Product to a Distribution Node). Add a target analogous to the unkits target. For example if you have:

distnode:  addproduct 

then add the target:

undistnode:  delproduct 

To remove the product, run the command:

% make undistnode
