#6378: Block Cache Memory Leak
---------------------------+------------------------------------------------
Reporter: jvff | Owner: nobody
Type: bug | Status: new
Priority: normal | Milestone: R1
Component: File Systems | Version: R1/alpha2
Resolution: | Keywords: block cache, memory leak
Blocked By: | Has a Patch: 1
Platform: All | Blocking:
---------------------------+------------------------------------------------
Comment (by jvff):
I ran block_cache.cpp through grep to find where stuff was assigned (ie.
grep "<src>.* = ") and I reached the following dependancy:
- original_data is either NULL, returned from Allocate or copied from
parent_data (where the leak originally occurred);
- parent_data is either NULL, returned from Allocate or copied from
current_data;
- current_data is returned from Allocate.
This (initially) leads me to the conclusion that a "false overwrite"
doesn't happen, which means the patch is (in theory) safe. However, it
would be better if someone with more knowledge of the code could confirm
this.
