Re: [dash-dev] optimizing an Athena build?
|
The previously provisioned target used to build is reused when creating
the test target - it's added to the list of repos from which IUs are
installed.
This means (in theory) that instead of refetching from Galileo, IUs will
simply be copied from the local disk. So the only thing that slows the
process down is file i/o.
Yes, we could even go a step further to use the existing eclipse instead
of creating a fresh, clean one, but that means a "dirty" test, and I
don't like that approach. Having this behaviour be optional is certainly
doable, but I'm sure people like Dave C will object violently to the
idea of setting up tests w/ chunks of leftover compilation artifacts in
them, instead of a clean "provision the target, install the built
runtime, install the tests, and run them" process.
It may be slower, but it's a more valid test IMO.
If you want an optional override to reuse the build environment instead
of creating a new one, please open a bug and propose the override
property name, eg., "useDirtyBuildEnvironmentForTesting" :)

Hi,
I'd like my build to be faster. I have noticed that Athena installs a
whole new Eclipse with all the dependencies specified in the
build.properties twice for each build (once for the build and a second
time for tests). That obviously takes quite some time.
Would it be possible to save the Eclipse install once the dependencies
are deemed stable, and re-use it for future builds? There could be a
property in the build.properties file that indicates the path of an
existing Eclipse install to use for the build for example.
If not, what would prevent this?
