ole32: Avoid unneccessary stream conversion.
...
Truncating a large stream to less than 0x1000 bytes would cause an
unnecessarily expensive conversion.

ole32: Flush the ILockBytes object of a storage on commit and final release.
...
Some ILockBytes objects will not really write changes until their Flush
method is called. Also, further optimizations to the storage implementation
will involve caching writes, which will have to be flushed at times.

ole32: Store the location of all blocks in a big block chain in memory.
...
A big block chain is a linked list, and we pretty much need random
access to them. This should theoretically make accessing a random
point in the chain O(log2 n) instead of O(n) (with disk access scaling
based on the size of the read/write, not its location). It
theoretically takes O(n) memory based on the size, but it can do
better if the chain isn't very fragmented (which I believe will
generally be the case for long chains). It also involves fetching all
the big block locations when we open the chain, but we already do that
anyway (and it should be faster to read it all in one go than
piecemeal).

ole32: Check the small block size limit of storage files.
...
This value is stored in the storage file header. We currently hard-code it to
0x1000. I don't expect to see files in the wild with other values, but
according to MS this is a valid configuration. For now, just fail if we see
another value.
I've also upgraded the message for unexpected values in storage file headers
to a fixme, since they are valid according to MS.

ole32: Track the lowest possibly-free small block in storage files.
...
This makes creating small block chains O(n) instead of O(n**2) because we
don't have to keep rechecking the first blocks in the file.
2010-03-22 10:47:42 +01:00

ole32: Remove knowledge of block sizes from the BigBlockFile object.
...
We can't determine the correct block size until we read the header, and we
can't create the BigBlockFile until we know the correct block size. To
solve this dilemma, have StorageImpl calculate the file size it needs instead
of asking the BigBlockFile to "ensure a big block exists".
2010-03-15 13:46:48 +01:00

ole32: Remove the NUM_BLOCKS_PER_DEPOT_BLOCK define.

This should always be calculated based on the big block size.
2010-03-15 13:46:31 +01:00
7b43123762
ole32: Remove the BIG_BLOCK_SIZE define.
...
Big block sizes can be 512 or 4096, so we define arrays that are large
enough in either case.
2010-03-15 13:46:19 +01:00
7f3211f383
ole32: Don't treat the header as a big block in StorageImpl_LoadFileHeader.

The header is always 512 bytes, regardless of the big block size.

ole32: Add a stub transacted storage type.
...
TransactedSnapshotImpl acts as a proxy between the user and the storage
interfaces that modify the file directly (or another transacted storage).
Currently, it does not change the operations.

ole32: Change the base IStorage filename to a pointer type.
...
The maximum size of the name returned by Stat() on a top-level storage has
nothing to do with DIRENTRY_NAME_BUFFER_LEN. Windows can return longer names
and probably has a limit of MAX_PATH. Also, Stat always returns an absolute
pathname, so we don't need a special case in StgOpenStorage.
