Patch to fix memory leak none

Description Derek Atkins 2006-09-18 18:50:20 UTC 
Description of problem:

there's a significant memory leak in the jasper library.

Version-Release number of selected component (if applicable):

jasper-1.701.0-12.fc5

How reproducible:

100%

Steps to Reproduce:
1. Run an application that uses the jasper library
2. See the size of the application continue to increase over time
3. Check google and see that the mem-leak patches haven't been applied.
  
Actual results:

My application (gyachi in this case) keeps increasing in size when I
send/receive webcam streams.  If it's just sitting there doing nothing then it
doesn't do anything.

Expected results:

Application memory use should stabilize, not constantantly increase.

Additional info:

See the attached patch for the correction.

Comment 2 Rex Dieter 2006-09-18 19:04:48 UTC 
This bit of the patch doesn't seem related to a memory leak:
-	tmpnam(obj->pathname);
+	mkstemp(obj->pathname);
(though it's probably better security-wise)

This looks more relevant:
...
+	jas_matrix_destroy(src_mgr->data);

> 3. Check google and see that the mem-leak patches haven't been applied.

Please, specific references (I can't find anything immediately searching on
"jasper memory leak" or "jasper mem-leak patches"
Comment 3 Derek Atkins 2006-09-18 19:08:07 UTC 
Two references to the memory leak:

http://ayttm.sourceforge.net/files.shtml   (where I got the patch)
http://gyachi.sourceforge.net/download.shtml  (page down to JasPer)

Unfortunately the SRPM link on the second page doesn't work anymore so I
couldn't pull that patch.
