Ben Johnson 440b89418f 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 7f2de9f17a Add DB.Check(). 2014-03-29 14:22:32 -06:00
Ben Johnson f45f1ed8d4 Fix DB.Copy() meta lock and partial write checks. 2014-03-26 10:11:31 -06:00
Ben Johnson f8ad21bad3 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 59fde2f664 Error refactoring. 
Fixed up a few error issues and refactored out the Error type.

Tommi Virtanen e9b2cab0fa Re-add tests for write failures 
Commit d2173f5f0e 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.

Conflicts:

Ben Johnson 3c1ecb925e Resolve remaining errcheck warnings. 2014-03-24 07:38:27 -06:00
Tommi Virtanen e0a6f5b2af 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.

Ben Johnson 76f6ead6b0 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.

Ben Johnson d2173f5f0e 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 3cc959fb1a 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.

Ben Johnson c551e45a47 Consolidate Tx and RWTx. 2014-03-08 20:40:48 -07:00
Ben Johnson 57376f0905 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.

Ben Johnson a1f43f4d60 Allow reads of unflushed nodes. 
This commit allows cursors to read updated values from within the
RWTransaction.

Ben Johnson 0477c1e0ce 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.
