default BOOST_PYTHON_LIB to boost_python; the test for exit symbol in that lib fails on my system and seems wrong

<PRE>Hello Joseph Nahmias,

To be able to write a recovery software, we did reverse-engineer the
Outlook 20003 format.

Now I decided to give some contribution (attached), so you can support
this format in some later version :-) (I recall it is not supported 
yet?). I welcome all questions or feedback on my information.

A Happy New Year!
Regards,
Alexander Grau

Outlook and Outlook2003 - The differences :-)


All values are LE byte order.

File Header
Ofs	Length		Meaning
0	4		Signature 0x4e444221
0x0a	2		Version
			0x000e: Outlook &lt; 2003 
			0x0017: Outlook &gt;= 2003

Outlook&lt;2003		
---------------------------------------------
Node size				516
size of ID1/2's	(IDsize)		4
size of file offsets (fileOfsSize)	4

File Header
Ofs	Length		Meaning
0xbc	4		index2RootNodeFileOfs
0xc4	4		index1RootNodeFileOfs

Index Node
Ofs	Length		Meaning
0x1f4	2		index node signature (8080/8181)
0x1f0	1		index node item count
0x1f1	1		index node max item count
0x1f3	1		index node level
0x29	1		typical index1 leaf node max item count
0x1f	1		typical index2 leaf node max item count
0x1f8	IDsize		back pointer


Outlook &gt;= 2003
---------------------------------------------
Node size				512
size of ID1/2's	(IDsize)		8
size of file offsets (fileOfsSize)	8

File Header
Ofs	Length		Meaning
0xe0	8		index2RootNodeFileOfs
0xf0	8		index1RootNodeFileOfs

Index Node
Ofs	Length		Meaning
0x1f0	2		index node signature (8080/8181)
0x1e8	1		index node item count
0x1e9	1		index node max item count
0x1eb	1		index node level
0x14	1		typical index1 leaf node max item count
0x0f	1		typical index2 leaf node max item count
0x1f2	IDsize		back pointer


In Outlook and Outlook 2003, the values in the other structures (e.g. inner nodes) have the same format, the only difference is the length of the ID1/2's and file offsets.

In my C++ implementation I managed this by using a buf class with functions for reading in all types of bit-lengths like this:


// read inner node records
bool PSTFile::readInnerNode(IndexNode &amp;node){
  tracef(&quot;readInnerNode fileOfs=%.0f\n&quot;, (float)node.fileOfsFound);
  unsigned __int64 firstId, backPtr, fileOfs;
  SaveBuf buf;
  if (!buf.malloc(olSpecs[olFmt].nodeSize)) return false;
  if (getAtPos(node.fileOfsFound, buf.buf, olSpecs[olFmt].nodeSize)) return false;

  if (!buf.seek(0)) return false;
  for (int i=0; i &lt; node.maxItemCnt; i++){
    IndexNodeRecord rec;
    if (!buf.numberLE(rec.firstId, olSpecs[olFmt].idSize)) break;
    if (!buf.numberLE(rec.backPtr, olSpecs[olFmt].idSize)) break;
    if (!buf.numberLE(rec.fileOfs, olSpecs[olFmt].fileOfsSize)) break;
    rec.node = NULL;
    if ( (rec.firstId != 0) || (rec.backPtr != 0) || (rec.fileOfs != 0) ) {
      node.indexNodeRecordList.push_back(rec);
      tracef(&quot;node record: firstId=%.0f, backPtr=%.0f, fileOfs=%.0f\n&quot;,
        (float)rec.firstId, (float)rec.backPtr, (float)rec.fileOfs);
    }
  }
  trace(&quot;\n&quot;);
  return true;
}
