Ben Johnson def455554b Add freelist cache. 
This commit adds a cache to the freelist which combines the available free pages and pending free pages in
a single map. This was added to improve performance where freelist.isFree() was consuming 70% of CPU time
for large freelists.

Ben Johnson c45c4a1ae6 Merge pull request #210 from benbjohnson/default-options 
Add DefaultOptions variable.
 2014-06-22 14:19:26 -06:00
Ben Johnson 642b104396 Add DefaultOptions variable. 
This commit adds an explicit DefaultOptions variable for additional documentation.
Open() can still be passed a nil options which will cause options to be change to
the DefaultOptions variable. This change also allows options to be set globally for
an application if more than one database is being opened in a process.

This commit also moves all errors to errors.go so that the godoc groups them together.

Ben Johnson 622c1f1525 Merge pull request #209 from benbjohnson/next-seq-uint64 
Change Bucket.NextSequence() to return uint64
 2014-06-22 10:00:04 -06:00
Ben Johnson 0f585358f4 Change Bucket.NextSequence() to return uint64. 
This commit changes NextSequence() to return a uint64 instead of an int. This also
removes the ErrSequenceOverflow error condition since overflowing a uint64 is unlikely.

Fixes #39.
 2014-06-22 09:33:28 -06:00
Ben Johnson 00ee0da528 Add Open() options, flock timeout. 
This commit changes Open() to provide an additional Options argument. The options
argument currently only has a Timeout which will cause the Open() to return
ErrTimeout if a file lock cannot be obtained in time.

Fixes #207.

 2014-06-19 07:17:36 -06:00
Ben Johnson b1dbd35da1 Fix merge-split regression. 
This commit reverts merge-split and fixes the node.split() to do a multi-page split. This issue
caused problems with bulk loading because it would split into a small page and a very large page.
The very large page, in turn, would be an arbitrary size so when it was freed later it would be
difficult to reuse and would cause serious fragmentation issues.

Ben Johnson 41aa602f27 Document key/value lifecycle. 
This commit adds a caveat to the godoc that explains how key and value
byte slices will only be valid for the life of the transaction.

Ben Johnson defdb743cd Fix deadlock on remmap. 
This commit fixes a deadlock situation that can occur when Bolt's database size crosses a threshold
and requires remapping the mmap.

Ben Johnson 1c97a490dd Add Windows support. 
This commit adds Windows support to Bolt. Windows memory maps return an address instead of a byte
slice so the DB.data field had to be refactored to be a pointer to a large byte array.

Increase max nodes per page.
 2014-06-10 10:06:01 -06:00
Ben Johnson fd7b0efeb5 Increase max nodes per page. 
This commit changes the maxNodesPerPage constant so that it is essentially unlimited.
Previously, a single large transaction could create more nodes than the mock array
could handle.

Fixes #188.

Ben Johnson 6ddb056698 Fix last element seek. 
This commit fixes a bug with seeks where seeking to a key between the end
of a page and the beginning of the next page causes it to return nil. This
was fixed by calling Cursor.next() when the cursor ends up between pages.

This also changes Cursor.Next() so that calling Next() at the end of a bucket
leaves the cursor at the end instead of zeroing out the stack.

Fixes #186.
