There should be no conflicts, because DLight creates files in /tmp/dlight_* with random names. But I'll double check. Valera, do you have any evidence of conflicts? No. Originally it was the question from issue 176167. What about /tmp/dlight_* or /var/tmp/dlight_*? Can we corrupt it, if 2 IDE is started? Mainly I had problems with cache from /tmp/*-cnd68-caches-0, but it is resolved. In latest test results I see very seldom exception only: Unexpected exceptions found in message.log ([Caused: org.netbeans.modules.masterfs.filebasedfs.utils.FSException: Cannot get exclusive access to /export/hudson/workspace/cnd-test-sparc-S2-2/tests/build/test/qa-functional/data/cnd/projects/TestAddCppOrCFiles/testAddMainCppFile1/files/dir/dir/file.cpp (probably opened for reading).]): But I think it is other problem. First can not create and use /tmp/dlight_*/experiment_1.er directory, but second delete it? OK, so here is what I've found. Potential conflicts on local host (there is some collision protection, but it works only within single NetBeans instance): DerbyDataStorage.<init>() - creates new database in tmpdir/derby_dlight/ without checking that the database does not exist yet H2DataStorage.<init>() - creates new database in tmpdir/h2_db_dlight/ without checking that the database does not exist yet SunStudioDataCollector.init() - creates new experiment in tmpdir/ without checking that the experiment does not exist yet Potential conflicts on remote host: UnbufferSupport.initUnbuffer() - uploads unbuffer libs to remote tmpdir/bin/nativeexecution/ LLDataCollector.init() - uploads agent and monitor to remote tmpdir/tools/ Alexey,
this issue was already discussed (and Valera was oresent, actually) ;)
But we already came to an agreement that we will have all dlight stuff in /var/tmp/dlight_username/${KEY}/...
where key is a hascode(?) of NBuserdir + local machine unique identifier.
