This commit adds support for writing small buckets directly inline to their value in
their parent's leaf node. Previously, subbuckets would simply have a bucket header
stored in their parent bucket which pointed to the root page. This required that
every bucket use at least a single page. This has a high overhead for buckets with
only one or two small items.
Inline buckets checks subbuckets to see if they only have a small amount of data
(about 1kb) and no subbuckets. If these conditions are met then the bucket's root
node is written to a fake page which is simply a pointer to the end of the bucket's
header.
Fixes#124.
This commit consolidates some of the smaller files into some of the larger files.
The smaller files cluttered the file tree and made it harder to see the logical
groupings of structs.
This commit makes a copy of the key byte slice before inserting into the database.
This fixes the issue where users may reuse byte buffers which can corrupt the database.
Fixes#143.
This commit pluralizes the BucketStat type to be BucketStats. This makes it
more consistent with the other Stats() calls. This commit also changes the
return type to a struct instead of a pointer.
Finally, this commit adds documentation to the fields of BucketStats.
This commit changes the API for:
Tx.CreateBucket()
Tx.CreateBucketIfNotExists()
Bucket.CreateBucket()
Bucket.CreateBucketIfNotExists()
These functions now return the *Bucket and error instead of just the error.
This commit adds performance counters for each transaction which are rolled
up to the database level on each commit/rollback. Counters are meant to be
a very fast way to track what is going on in the database. A few timers are
also added in areas where the time.Now() overhead is not noticible.
The DB.Stat() function is now deprecated since the `bolt` CLI now performs
similar functions.
Fixes#108.
Commit/Rollback and mutable calls on Tx and Bucket now return ErrTxClosed
if the transaction has already been committed or rolled back. Non-mutable
calls have added an assertion to check if the transaction is closed which
will cause a panic. I don't want to introduce an error return for accessor
methods that are being used improperly so I think the panic is appropriate.
I changed the Transaction/RWTransaction types to Tx/RWTx, respectively. This makes the naming
more consistent with other packages such as database/sql. The txnid is changed to txid as well.
