Ben Johnson 2ee5806031 Merge pull request #179 from benbjohnson/freelist-assertion 
Add freelist assertion on every free().
 2014-05-29 08:17:54 -06:00
Ben Johnson 2eaf8f7ce0 Add freelist assertion on every free(). 
This commit performs a check on the freelist pages to ensure that a double free can never happen.

Optimize Tx.Check().
 2014-05-28 13:10:20 -06:00
Ben Johnson 754966bea0 Optimize Tx.Check(). 
This commit removes several memory allocations occurring on every page and also caches the freelist map used when iterating over the pages. This results in significantly better performance.

Tommi Virtanen 394862d541 Do not attempt manual transaction rollback in Tx.Copy 
The typical use these days is with a managed transaction, via db.View.

The first case (error when re-opening database file) is not tested;
it is harder to instrument, and I have other plans for it.

Ben Johnson b9b1bb5b29 Merge pull request #176 from benbjohnson/streaming-check 
Add streaming check.
 2014-05-28 10:46:21 -06:00
Ben Johnson b789691976 Add streaming check. 
This commit changes Tx.Check() to return a channel through which check errors are returned. This allows
errors to be found before checking the entire data file.

Ben Johnson 4508a00891 Merge pull request #175 from benbjohnson/check-loop 
Add circular dependency integrity check.
 2014-05-28 09:00:19 -06:00
Ben Johnson cefc3c5ebd Add circular dependency integrity check. 
This commit adds a check to prevent circular dependencies in branch nodes. If a circular dependency occurs
then a panic will be called and the commit will be prevented. This only works for a single branch level
and will not recursively search the tree.

Ben Johnson 93338e17ec Merge pull request #174 from benbjohnson/remove-db-check 
Remove DB.Check(). Allow read-only Tx.Check().
 2014-05-27 12:08:33 -06:00
Ben Johnson 92a9f2e200 Remove DB.Check(). Allow read-only Tx.Check(). 
This commit removes the DB.Check() function and instead makes the user decide
whether a transaction should be writable or read-only. Tx.Check() is not safe
to use concurrently on a read-only transaction, however, it significantly
improves the performance of it.

Ben Johnson bfccbb2cb5 Avoid trashing page cache on Tx.Copy(). 
This commit change the database copy to use O_DIRECT so that the Linux page
cache is not trashed during a backup. This is only available on Linux.

Ben Johnson 782ead0dbf Fix freelist allocation direction. 
This commit fixes the freelist so that it frees from the beginning of the data file
instead of the end. It also adds a fast path for pages which can be allocated from
the first free pages and it includes read transaction stats.

Ben Johnson a1873dd6f6 Add option to adjust fill percentage. 
This commit adds the ability to adjust the fill percentage for splitting nodes. This
works by setting a threshold that is a percentage of a total page size. When that
threshold is crossed during a split then a new node is created.

This is primarily beneficial for append-only workloads.

Fixes #163.
