This functionality currently only works correctly when no transactions are used. * Started test application for the block cache, doesn't do anything yet. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28496 a95241bf-73f2-0310-859d-f6bbb57e9c96 diff 5d0afa4e Fri Jan 18 10:07:18 MST 2008 Axel Dörfler <axeld@pinc-software.de> * cache_detach_sub_transaction() didn't really work: it did not put all needed blocks into the new transaction, but it would set that transaction on all blocks of the old transaction, too. Also, it did not correctly update the num_blocks/sub_num_blocks fields of the old transaction. Even worse, it did return B_OK instead of the ID of the new transaction... * get_writable_cached_block() did not correctly maintain the number of blocks in the sub transaction. * write_cached_block() did not free the original_data of a block when it wrote it back as part of a previous transaction. * Changed "cookie" for cache_next_block_in_transaction() to "long", so it will be 64 bits when needed. * Improved the API for detaching sub transactions: you can now get the blocks of only the main (parent) transaction as well, added new cache_block_in_main_transaction() function. * BFS now flushes the log when there is no space left for the current transaction. * _WriteTransactionToLog() allocated a "vecs" array, but never freed it. * _WriteTransactionToLog() now also supports detaching the current sub transaction if the whole thing is getting too large (it will now also panic if that doesn't work out). * Removed a useless optimization: making the blocks available in the cache isn't really needed, as all blocks in a transaction are locked into the cache, anyway. * Implemented Transaction::WriteBlocks(). * Minor cleanup, removed some dead code, fixed warnings in the fs_shell's block_cache when compiled with debug output on. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23610 a95241bf-73f2-0310-859d-f6bbb57e9c96 diff 5c03270b Tue Apr 24 18:07:30 MDT 2007 Axel Dörfler <axeld@pinc-software.de> Added block_cache_sync_etc() that allows you to sync single blocks. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20811 a95241bf-73f2-0310-859d-f6bbb57e9c96 diff 5c03270b Tue Apr 24 18:07:30 MDT 2007 Axel Dörfler <axeld@pinc-software.de> Added block_cache_sync_etc() that allows you to sync single blocks. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20811 a95241bf-73f2-0310-859d-f6bbb57e9c96 diff 5b812019b48c620b3cdc4e15f59fe3f34b431a43 Tue Nov 04 07:49:33 MST 2008 Axel Dörfler <axeld@pinc-software.de> * Added function block_cache_discard() that flushes blocks from the block cache, discarding their changes.

This introduces the following relevant changes: * VMCache: - Renamed vm_cache to VMCache, merged it with vm_store and made it a C++ class with virtual methods (replacing the store operations). Turned the different store implementations into subclasses. - Introduced MergeStore() callback, changed semantics of Commit(). - Changed locking and referencing semantics. A reference can only be acquired/released with the cache locked. An unreferenced cache is deleted and a mergeable cache merged when it is unlocked. This removes the "busy" state of a cache and simplifies the page fault code. * Added VMAnonymousCache, which will implement swap support (work by Zhao Shuai). It is not integrated and used yet, though. * Enabled the mutex/recursive lock holder asserts. * Fixed DoublyLinkedList::Swap(). * Generalized the low memory handler to a low resource handler. And made semaphores and reserved memory handled resources. Made vm_try_resource_memory() optionally wait (with timeout), and used that feature to reserve memory for areas. ... git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26572 a95241bf-73f2-0310-859d-f6bbb57e9c96 diff 5af13da1 Mon Jan 21 13:34:06 MST 2008 Axel Dörfler <axeld@pinc-software.de> * The block cache now sorts the blocks before synchronizing a transaction. * This should speed up writing a transaction considerably. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23694 a95241bf-73f2-0310-859d-f6bbb57e9c96 diff 5f7a62cf Sat Jan 19 10:01:26 MST 2008 Axel Dörfler <axeld@pinc-software.de> * Added debugger command "transaction" and added a new "-t" option to "block_cache" to dump info about transactions. * Improved tracing. * Now uses the new add_debugger_command_etc(). git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23644 a95241bf-73f2-0310-859d-f6bbb57e9c96 diff 5d0afa4e Fri Jan 18 10:07:18 MST 2008 Axel Dörfler <axeld@pinc-software.de> * cache_detach_sub_transaction() didn't really work: it did not put all needed blocks into the new transaction, but it would set that transaction on all blocks of the old transaction, too.
