Rake: race condition between task prerequisites

ruby-talk
1

Hi,

I'm having a strange race condition between task prerequisites in the
following rakefile:

At line #49, the :test rake tasks has the following prerequisites:
:build_tests, :dist and :test_units.

:build_tests is correctly executed, as the files are generated, but
:test_units doesn't wait for the files to be generated before running.

So the first time you run :test, no tests are called. (Subsequent calls
do work, though).

I'm really not sure what I should be looking at to solve this problem.

Any pointers are welcomed.

Thanks,

Tobie

:build_tests is correctly executed, as the files are generated, but
:test_units doesn't wait for the files to be generated before running.

If :test_units needs the result of :build_tests, the latter should be a
prerequisite of the first.

You mean as in: http://pastie.caboo.se/184892 ?

I had tried that earlier too (tried it again now to double-check),
problem persists.

Hi again,

I ended up solving the issue. Turns out what I though was a block for
the task was actually the block defining the task.

Sorry for the hassle.

Best,

Tobie

Yes, why put it there instead just posting it here?

But the race condition is another thing, independent of the task doing
the wrong thing.
