|
|
* Used to keep track of nsDiskCacheBinding associated with active/bound (and
|
|
* possibly doomed) entries. Lookups on 4 byte disk hash to find collisions
|
|
* (which need to be doomed, instead of just evicted. Collisions are linked
|
|
* using a PRCList to keep track of current generation number.
|
|

|
* Used to detect hash number collisions, and find available generation numbers.
|
|
*
|
|
* Not all nsDiskCacheBinding have a generation number.
|
|
*
|
|
* Generation numbers may be aquired late, or lost (when data fits in block file)
|
|
*
|
|
* Collisions can occur:
|
|
* BindEntry() - hashnumbers collide (possibly different keys)
|
|
*
|
|
* Generation number required:
|
|
* DeactivateEntry() - metadata written to disk, may require file
|
|
* GetFileForEntry() - force data to require file
|
|
* writing to stream - data size may require file
|
|
*
|
|
* Binding can be kept in PRCList in order of generation numbers.
|
|
* Binding with no generation number can be Appended to PRCList (last).
