Description Andrew Korostelev 2006-08-15 17:36:54 UTC 
when uml module copies dotuml.zip to userdir the same filename is always used
for file created in tmp directory.

For unix systems it may cause impossibility to use UML after the following
situation:
- user1 starts IDE. 
- At the moment when dotuml.zip is copied to tmp dir, user1 kills installation
process. dotuml.zip with 'rw-r--r--' permissions stays in tmp dir.
- user2 tries to use ide, but can't use uml because ide can't initialize user's
properties (can't copy dotuml.zip to tmp dir and extract it to userdir. Rised
Exception is provided below).

The only possible solution is to remove dotuml.zip from tmp dir, but it needs
user1 or root permissions


java.io.FileNotFoundException: /var/tmp/dotuml.zip (Permission denied)

Comment 1 Andrew Korostelev 2006-08-15 17:39:27 UTC 
It is unusual situation.
But when it happens, user is confused and uml can't be used at all even by other
users. Reinstallation also does not help.
Thus I file it as P1.
Comment 2 Yang Su 2006-09-20 23:03:37 UTC 
Re-implemented the logic to extract uml.zip to user dir, it's not needed to copy
it to a temp directory anymore.
Comment 3 Andrew Korostelev 2006-09-27 14:59:44 UTC 
verified in uc-only-nbms-main-060927.zip

I was able only to check that there was no attempt to copy or extract uml zip
into  temp directory.
