\class DirManager
|
|
\brief Creates and manages BlockFile objects.
|
|
|
|
This class manages the files that a project uses to store most
|
|
of its data. It creates NEW BlockFile objects, which can
|
|
be used to store any type of data. BlockFiles support all of
|
|
the common file operations, but they also support reference
|
|
counting, so two different parts of a project can point to
|
|
the same block of data.
|
|
|
|
For example, a track might contain 10 blocks of data representing
|
|
its audio. If you copy the last 5 blocks and paste at the
|
|
end of the file, no NEW blocks need to be created - we just store
|
|
pointers to NEW ones. When part of a track is deleted, the
|
|
affected blocks decrement their reference counts, and when they
|
|
reach zero they are deleted. This same mechanism is also used
|
|
to implement Undo.
|
|
|
|
The DirManager, besides mapping filenames to absolute paths,
|
|
also hashes all of the block names used in a project, so that
|
|
when reading a project from disk, multiple copies of the
|
|
same block still get mapped to the same BlockFile object.
|
|
|
|
The blockfile/directory scheme is rather complicated with two different schemes.
|
|
The current scheme uses two levels of subdirectories - up to 256 'eXX' and up to
|
|
256 'dYY' directories within each of the 'eXX' dirs, where XX and YY are hex chars.
|
|
In each of the dXX directories there are up to 256 audio files (e.g. .au or .auf).
|
|
They have a filename scheme of 'eXXYYZZZZ', where XX and YY refers to the
|
|
subdirectories as above. The 'ZZZZ' component is generated randomly for some reason.
|
|
The XX and YY components are sequential.
|
|
DirManager fills up the current dYY subdir until 256 are created, and moves on to the next one.
|
|
|
|
So for example, the first blockfile created may be 'e00/d00/e0000a23b.au' and the next
|
|
'e00/d00/e000015e8.au', and the 257th may be 'e00/d01/e0001f02a.au'.
|
|
On close the blockfiles that are no longer referenced by the project (edited or deleted) are removed,
|
|
along with the consequent empty directories.

saved version of the old project must not be removed because of operations

Copy also happens anyway when hard file links are not possible, as when

saving the project for the first time out of temporary storage and onto

some other storage device.
|

|
|
Renaming would also be cheap like hard-linking, but linking is better

because it builds up a new tree of files without destroying anything in

|
the old tree. That destruction can be left to a commit phase which
|
|
proceeds only when all the building of the new tree has succeeded.
