Vincent Povirk e40afcb2b6 ole32: Always move unmodified streams instead of copying on commit. 2010-05-06 17:55:43 +02:00
Vincent Povirk d07a4868a1 ole32: Rewrite transacted storage to be more lazy.
When creating a new transacted storage object (or reverting an
existing one), rather than copy the original storage, we simply create
a "stub directory entry" for the root. As stub entries are accessed,
we fill in their data from the parent and create new stubs for any
linked entries. The streams have copy on write semantics - reads are
from the original entry until a change is made, then we make a copy in
the scratch file.

When committing transacted storages, we have to create a new tree with
the new data so that the storage entry can be modified in one step,
but unmodified sections of the tree can now be shared between the new
tree and the old. An entry can be shared if it and all entries
reachable from it are unmodified. In the trivial case where nothing
has been modified, we don't have to make a new tree at all.

Nikolay Sivov 56fdbc226e ole32/ole2: Use W calls for registry access. 2010-05-06 14:22:23 +02:00
Vincent Povirk 42550953a6 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).

Mikhail Maroukhine f930c87fd6 objbase.h: CLSIDFromString: Add constness to the parameters declaration in accordance with MSDN. 2010-03-29 12:11:02 +02:00
Vincent Povirk 49a817c064 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.

Vincent Povirk 975c820fce ole32: Don't register an IMallocSpy object when the ole trace is used.
There's no need for this. Any useful information we could get out of it
is availble from the olemalloc channel, and it means that the ole channel
changes behavior in a way that's visible to programs.

Vincent Povirk e05b8416b8 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.

Vincent Povirk 93c2256cff ole32: Allow storage files with a block size of 4096 to open. 2010-03-15 13:46:59 +01:00
Vincent Povirk 5ceb003a24 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".

Vincent Povirk 926669741e 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
Vincent Povirk 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.

Vincent Povirk b90ab46a82 ole32: Remove the unused BlockBits structures from BigBlockFile objects. 2010-03-15 13:46:07 +01:00
Vincent Povirk 4b7e7bd77f ole32: Fix the big block offset calculation.
Use the actual big block size from the open storage file. Also, remove a
special case that was only used for reading/writing the header.

Vincent Povirk 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.
