[Kde-bindings] crash testing a korundum application with rspec and ruby 1.8.7-p160

Sun May 10 13:11:39 UTC 2009

I'm using rspec to test my korundum4 application (with latest svn revision of 
both kde and korundum). I have a sets of tests which, until yesterday, worked 
correctly. Yesterday, I installed ruby 1.8.7-p160 (before I used ruby-1.8.7-
p72) and suddnely I got a number of crashes. Looking at the changelog for 
ruby-1.8.7-p72, I noticed two entries related to the function run_final 
mentioned in the stack traces I got from the crashes. Those entries are:

* gc.c (run_final): frees zombies only
* gc.c (run_final): calls free function

I tried disabling the GC and indeed the tests stopped crashing. Since I don't 
know neither korundum nor ruby C internals, I understand very little of the 
stack traces I got, so, after some useless attempts at fixing the issue, I 
decided to ask for help.

I attach a file with the stack trace I got from the crash and the two files 
needed to reproduce it. Unfortunately, to reproduce them you need to have 
rspec ([1]) and flexmock ([2]) installed. To reproduce it, use the following 
command:

rspec -f html document_spec.rb

This will invoke rspec on the document_spec.rb file and output the result 
using a formatter (included with rspec) which displays the output as html. 
Omitting the -f html part, that is using the default rspec formatter, doesn't 
produce a crash. Using a custom formatter I wrote produces a similar crash in 
other places.

With the procedure I explained above, I get a crash in the before block of the 
last test (describe 'KRuby::Document#file_type_match?'). As the name says, 
'before' blocks are called before each test (which are the blocks passed to 
the 'it' methods), in particular on line 119 (the string "before creating doc" 
is printed but "after creating doc" is not). As I said above, uncommenting the 
line "GC.disable" makes the crash disappear. What I found more strange is that 
commenting out some of the tests in the "KRuby::Document#close" group also 
makes the crash disappear (I haven't been able to find out whether there are 
specific tests you need to comment out or not. It got the impression there's a 
bit of randomness in this). In theory, different groups of tests should be 
indipendent from each other.

The at_exit{Qt::Internal.application_terminated = true} block is there because 
it has been suggested to me as a way to avoid issues due to 
KDE::Application#exec not being called. However, its presence doesn't seem to 
make any difference in this case.

I must add that the application these tests refer to still works correctly. 
The crashes only happen in the tests.

Any suggestion about how to fix this issue (other than disabling GC) will be 
welcome. If you need more information, please ask.

Thanks in advance

Stefano
