Fixed size sub-view-block buffer #6

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
To avoid the use of Malloc() for every new svb a buffer is introduced in r237. 
However, since the buffer has a fixed size, a buffer overflow is a possibility. 
It may not be possible to flush the svb-DAG to avoid a buffer overflow, since 
we compute a complete view-block at a time and it is not guaranteed that the 
size of a single view-block does not excites the fixed buffer size.

A solution is to compute a single sub-view-block at a time and then guarantee 
that the size of one svb does not excites the buffer size. An attempt to do 
this is attached this issue, but it is a non-working draft.

This is not a problem anymore because of the new work buffer introduced in r240.
