[Torch5-devel] API Changes: MapStorage

[Ronan C. <ro...@co...>]

Hey

   (1) Due to some serious bugs in MapStorage, I had to modify the  
API. Sorry.
   MapStorage no longuer exists. It is now handled by a new  
constructor of Storage.

   Ex: torch.CharStorage(fileName, shared)

   If the optional argument "shared" is true, the mapping will be  
shared amongst all processes on the computer. In that case, the file  
must be with read-write access. Modifications made on the storage  
will then be reflected in the file. This corresponds to the old  
behavior of MapStorage.

   If "shared" is false (or not provided), the file must be at least  
readable. Modifications made on the storage will not affect the file.

   This fixes the bug reported by Gregoire about segfault when  
freeing a MapStorage.

   (2) A new shortcut to create a 1D Tensor over a Storage has been  
added.
         Ex: s = torch.DoubleStorage(100)
                t = torch.Tensor(s) -- in previous versions you had  
to do torch.Tensor(s, 1, s:size())

The doc has been updated accordingly for (1) and (2) in the SVN.

Cheers
Ronan.
