Re: [wtp-releng] Batch Build questions

[David M Williams <david_williams@xxxxxxxxxx>]

1. In general, we use environment variables
when something is used by other scripts besides ant. In some cases it might
be because I wanted to use OS path mechanisms to have machine specific
information found easily, while the invocation method (from CruiseControl)
stays the same. 

2. Not sure what you mean. You have
to get at least the build script. that's step two in the document you reference.
Everything else is checked out automatically. 
Oh, do you mean the JVMs and ANT in
step 1? Sure, feel free to contribute. (Although, seems kind of hard to
do it well, and IMHO there's more important things to improve). I suspect
you mean something else that I'm not seeing. 

3. This is a statement, not a question.
:)  

And, as I've said before .. have at
it. Contributions are always welcome. There are some "criteria and
principles" that have to be met, so I suggest 1) small, incremental
contributions at first, to learn the ropes and insure steady improvement
without risking big breakages, and 2) some principles are spelled out in
previous bugzilla entries, so be sure read them, such as  https://bugs.eclipse.org/bugs/show_bug.cgi?id=211287#c1
... none of which contradict what you say ... but, spells out a little
more of the theory and requirements of our builds.  I don't mean be
discouraging. Tons of improvements are possible, some easy, some hard,
there are bugzillas already open for many of them, and you are welcome
to open others ... so hop right in!  And feel free to ask questions,
either here on wtp-releng, or in bugzillas you open.

Subject:	[wtp-releng] Batch Build questions

---

I was reviewing the Batch Build document and have
a couple of questions:

http://wiki.eclipse.org/WTP/Build/WTP_Batch_Build

1.  Why are we relying on Environment Variables to be set instead
of 
using ANT property variables, that can be passed into the ANT build.  
Particular candidates for property files and ant properties are:

        LOCAL_BUILD_PROPERTIES_DIR to the copied properties
directory
        from the last step 

        BUILD_CVS_READ_PROTOCOL = pserver 
        BUILD_CVS_READ_USER=anonymous 
        BUILD_CVS_WRITE_PROTOCOL=pserver 
        BUILD_CVS_WRITE_USER=anonymous 
        BUILD_CVS_SERVER=dev.eclipse.org 

        SKIPUSER=true 


All of the above can be specified as an ANT property and passed in when
the ant build script is completed.

2.  Shouldn't the ANT build script automatically check out all the
files 
if necessary.   As it is right now you have to do this manually outside
of the build script.

3.  Ideally only specifying the ant build.xml command line should
be 
necessary to get a build.   If we eliminate the Environement variables
then we can use a standard property file if necessary to set these 
values....But ideally, they should be set by default, and overriden when
necessary.
