| 2014-04-04 | Add Tx.OnCommit() handler.•••This commit adds the ability to execute a function after a transaction has
successfully committed.
| Ben Johnson | 2 | -12/+58 |
| 2014-04-03 | README•••Add 'Scuttlebutt' to list of projects that use Bolt. | Ben Johnson | 1 | -0/+1 |
| 2014-04-02 | Add meta page checksums.•••This commit adds checksums to the meta pages on every write. When the
database loads, it verifies the checksums on the meta pages and returns
an error if either one is corrupt.
In the future, it should fallback to the previous meta page but for right
now it just hard fails. This is at least preferable to opening the database
and getting a random error or further corruption.
Fixes #25.
| Ben Johnson | 3 | -10/+55 |
| 2014-04-02 | Add performance counters.•••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.
| Ben Johnson | 8 | -100/+160 |
| 2014-04-02 | Add advisory file locking.•••This commit adds advisory locking via flock() to the database file. This ensures that two separate
processes cannot both open the same data file which would cause corruption.
Fixes #110.
| Ben Johnson | 1 | -0/+12 |
| 2014-04-02 | Consolidate file and metafile descriptors.•••Previously, a two file descriptors were used for the database: file & metafile. The "file" file
descriptor was used for async writes while the "metafile" file descriptor was used with O_SYNC
writes. This commit changes that so that there's only one file descriptor and it uses fdatasync()
to synchronize writes.

| 2014-04-02 | README•••Remove the 'Internals' section since it is half-assed right now. | Ben Johnson | 1 | -30/+1 |
| 2014-04-02 | Remove count and overflow columns for free pages on 'bolt pages'.•••The count and overflow columns are meaningless for freed pages since
there could be random overflow data in there. This commit removes those
columns for free pages.
| Ben Johnson | 1 | -4/+12 |
| 2014-03-31 | Add DVID to projects using Bolt•••DVID added Bolt as an optional storage engine. | Bill Katz | 1 | -0/+1 |
| 2014-03-31 | Remove DB.Open() and only allow bolt.Open().•••Per @tv42's suggestion, this commit removes the ability to reopen an
instance of DB. All open calls go through bolt.Open().
Fixes #103.
| Ben Johnson | 4 | -124/+79 |
| 2014-03-31 | Write freelist after each commit.•••Well, this is embarassing. Somehow the freelist was never getting written after each commit.
This commit fixes that and fixes a small reporting issue with "bolt pages".
| Ben Johnson | 6 | -10/+51 |
| 2014-03-29 | Add DB.Check(). | Ben Johnson | 7 | -1/+140 |
| 2014-03-27 | Refactor bolt commands into individual files. | Ben Johnson | 11 | -316/+395 |
| 2014-03-26 | Fix DB.Copy() meta lock and partial write checks. | Ben Johnson | 1 | -1/+12 |
| 2014-03-25 | Fix quickcheck test for duplicate keys. | Ben Johnson | 1 | -4/+15 |
| 2014-03-25 | Fix bucket reclamation.•••The bucket page is allocated separately from the rest of the pages but the old bucket pages were
not being added to the freelist. This change fixes that and adds a simple check for database
consistency. More advanced consistency checks can be added in the future.
Fixes #82.
| Ben Johnson | 3 | -9/+52 |
| 2014-03-24 | README•••Add a list of "Other Projects Using Bolt". | Ben Johnson | 1 | -0/+7 |
| 2014-03-24 | Make DB/Tx API more consistent.•••I consolidated the DB.Tx() and DB.RWTx() calls into a single
DB.Begin(writable bool) call. This is more consistent with the
database/sql library.
I also changed the DB.Do() and DB.With() call to DB.Update() and
DB.View(), respectively. This is more intuitive and more inline with
other database verbiage.
| Ben Johnson | 8 | -149/+157 |
| 2014-03-24 | Error refactoring.•••Fixed up a few error issues and refactored out the Error type.
| Ben Johnson | 8 | -106/+94 |
| 2014-03-24 | Re-add tests for write failures•••Commit d2173f5f0ecbf4ed93c768e975435b04df3186ec removed the complete
os & syscall mocking layer as overly complex. This commit adds back
the simplest possible thing: hooks to control the database file
writes.
Missing tests: TestDBOpenMetaFileError, TestDBMmapStatError.
These are harder to test without more extensive mocking.

| 2014-03-24 | Resolve remaining errcheck warnings. | Ben Johnson | 2 | -11/+29 |
| 2014-03-23 | Check errors from file close in DB.CopyFile•••Write errors are often delayed and reported only by the close.
The extra close in defer on success is harmless, (*os.File).Close
protects itself against multiple closes, and this way it's immediately
obvious there is no code path that would leak open files.

| 2014-03-23 | Check meta page write error in Commit | Tommi Virtanen | 1 | -1/+3 |
| 2014-03-23 | Add ErrTxClosed error.•••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.
| Ben Johnson | 5 | -17/+89 |
| 2014-03-23 | Mark Do()/With() transaction as managed.•••Transaction created from Do() and With() are now considered "managed".
Managed transactions cannot be manually committed or rolled back since
the Do() and With() functions provide that functionally automatically.
Previously, a Tx could be manually committed and then any changes after
that would be lost.

| 2014-03-22 | Call fdatasync/fsync after writing out non-meta pages•••This avoids a case where writes can be reordered so meta page is
written before a page it refers to, potentially causing a corrupt
database after a power loss or kernel crash.

| 2014-03-21 | Fix db.munmap() to return an error.•••Changes munmap to return an error and the DB now implements io.Closer.
I also removed all the OS and Syscall mocking because it's causing issues.
Corrupt file tests need to be recreated but directly using the file system
instead.
| Ben Johnson | 9 | -347/+36 |
| 2014-03-21 | Remove ease-of-use functions from the DB type.•••Functions such as DB.Put(), DB.Get(), and DB.Delete() were originally
added to be easy to use, however, after implementing Bolt in multiple
projects I have found these ease-of-use functions useless. Nearly
every use case requires multiple calls in a single transaction.
Using the DB ease of use functions turned out to be an antipattern.

| 2014-03-13 | Fix Tx.Buckets() sort order.•••@tv42 reported an issue with bucket names returning incorrectly. Not sure if
this fixes the issue but it is necessary anyway.
| Ben Johnson | 2 | -0/+7 |
| 2014-03-13 | Fix Cursor.Last() on empty buckets.•••@tv42 reported that creating a cursor on an empty bucket and then calling
Cursor.Last() causes an index out of range error and panics. This commit
adds a check for the page's item count being greater than zero.
Fixes #63.

| 2014-03-08 | Rename Transaction to Tx.•••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.

| 2014-02-27 | Fix the mmap resize to use the correct size.•••Fixes #54. Previously the DB was calculating a minimum mmap size but
using the wrong variable after it calculated the size. This commit
changes the DB to use the correct variable.

| 2014-02-27 | Add bucket reclamation.•••After RWTransaction.DeleteBucket() is called, all pages related to the
bucket are moved to the freelist for that transaction.
