33 // Server memory leak checking - this is a contentious thing because the |
|
34 // only sure "leak" is when dynamic memory is 100% orphaned, ie no pointer |
|
35 // from the root class to it, which we can't determine. The checking in this |
|
36 // code used to be at the level of the socket operations, ie like: |
|
37 // iSockServer.__DbgMarkHeap(); |
|
38 // ret = socket.DoSomething(); |
|
39 // if(ret == KErrNoMemory) |
|
40 // iSockServer.__DbgMarkCheck(); |
|
41 // but this explicitly requires that upon a OOM condition the SAP will unwind |
|
42 // any allocations, such as recv queues, and this is not true and isn't stated |
|
43 // in any "contract" - it used to work purely because the recv queue was the |
|
44 // last thing allocated, but now the shim introduces a later allocation. |
|
45 |
|
46 // So here we move the heap mark/check outside all of the socket handling, on |
|
47 // the assumption that once all the SAPs are closed then all memory will have |
|
48 // been returned. This is still a weak assumption, eg what if the protocol keeps |
|
49 // a dynamic array of SAPs, then even once the SAPs have been freed this still |
|
50 // preserves a "high water mark" (unless the array is compressed) |
