Dawid Weiss commented on SOLR-4195:
-----------------------------------
bq. It must be a sysprop and it must be absolute in platform specific
(File.absolute!) notation.
I assume you cannot just do new File(".").getAbsolutePath()?
bq. the inter process communication files should maybe placed in a separate
subdirectory and next to the J0, J1 dirs,
http://labs.carrotsearch.com/download/randomizedtesting/2.0.0/docs/junit4-ant/Tasks/junit4.html
See the 'tempdir' attribute. If you provide it to <junit4> it'll just use it.
Don't know how it's going to handle the restrictive policy though -- never
thought it'd run with a security manager, really.

> Until recently, I thought the solr test framework was setup such that every
> test got it's own copy of the "test-files/solr" directory to use as it's Solr
> Home Dir -- then mark committed r1421543, to fix a problem where that test
> was writing a file (that would later be removed) to the solr conf dir, which
> would confuse another currently running test and cause it to fail.
> This made me realize that what i was remembering is that the ant build files
> copy the src/test-files directories into build/ prior to running the tests --
> but all tests (in that module) still share the same copy.
> Subsequent discussions with folks on IRC lead me to the following
> realizations..
> * making a copy of the test-files dir for each test would help eliminate
> confusing by reducing non-reproducible failures if tests collide -- but might
> be slow
> * making a copy of the test-files dir for each test would not help identify
> situations were code was mistakenly/unexpectedly writing to the solr home dir
> * what would probably make the most sense, would be to make the
> build/test-files directory "read only". that way by default tests would get
> a read only solr home dir -- triggering failures if the code is broken and
> tries to write to that dir. tests that want/need to write to the solr home
> dir would have to go out of their way to clone the read only test-files/solr
> directory and use it as their solr home.
