* Block allocation is now first-fit.
* There is a better test for the block allocator.
* brt_stat64 returns data in a struct instead of a bunch of arguments.
* Nodes are set clean after serialization.

Cursors take a copy of oldest living xid upon creation, which they use for implicit promotion
git-svn-id: file:///svn/toku/tokudb@13606 c7de825b-a66e-492c-adef-691d508d4ae1
Added versioning to descriptor.
Changing a descriptor REQUIRES the version to increase.
Version 0 is reserved for a non-descriptor db. (cannot be set).
Not yet added to brtnodes.
Still possible to change descriptor with an open brt (which would not be upgraded).
git-svn-id: file:///svn/toku/tokudb@11198 c7de825b-a66e-492c-adef-691d508d4ae1
Several fixes are included, particulary db remove after db truncate (with descriptor) does not crash anymore.
svn merge -r 10931:11019 ../tokudb.1510
git-svn-id: file:///svn/toku/tokudb@11020 c7de825b-a66e-492c-adef-691d508d4ae1
Abstracted out the block translation table and the block allocator
into BLOCK_TABLE
All use is done by accessors surrounded by locks.
git-svn-id: file:///svn/toku/tokudb@9360 c7de825b-a66e-492c-adef-691d508d4ae1
Fixes#1381. Addresses #1393 which was also fixed in this branch.
{{{

and delete the 1381 branch.

Global mutexes are now initialized in toku_ydb_init, destroyed in toku_ydb_destroy.
Globals in tdbtrace.c (not default) are not yet initialized.
git-svn-id: file:///svn/toku/tokudb.1032b@8149 c7de825b-a66e-492c-adef-691d508d4ae1
Created function that peeks at both key and value at the same time
(to avoid repeated OMT calls).
This was worth 4-5% performance in scanscan --lwc --prelock --prelockflag
git-svn-id: file:///svn/tokudb@5386 c7de825b-a66e-492c-adef-691d508d4ae1
Removed extra mallocs and memcopies for toku_c_get
when the dbts use anything other than DB_DBT_USERMEM
git-svn-id: file:///svn/tokudb@4121 c7de825b-a66e-492c-adef-691d508d4ae1
Bugfix with the way data was copied out to static buffers.
Now (again) copies to cursor's temp storage if it is not a temporary cursor
if it is a db handle call, or a temporary cursor, it will use the db's temporary storage.

Also the file numbers can thus be reused.
Don't pass the BRT into the flush commands, since the BRT may no longer be present.
Put a counter in to see how many rollback records are present. (Addresses #698.)
Increment the file version to 4.
Fixes#545, #703.
Note: All the tests pass except
* Many cxx tests are getting valgrind errors. (Addresses #716. Possibly causes #716.)
* {{{test_log9.recover}}} fails with "Binary files ... differ". These will presumably be fixed by #711 or #714. (Addresses #711, #714.)
* {{{test_log10.recover}}} fails. There are two failures:
1. A valgrind problem (see #718.) (Addresses #718. Possibly causes #718.)
1. The "Binary files ... differ" issue.

Make txn->abort work without bombing out for {{{test_txn_abort5}}} one case. Fixes#431.
Start writing {{{test_txn_abort6}}}. Addresses #443.
Try to write a test for #399 and #400, but haven't managed to reproduce the problem. Addresses #399, #400.
Write a test for #332. Addresses #332.
git-svn-id: file:///svn/tokudb@2406 c7de825b-a66e-492c-adef-691d508d4ae1
Deals with NULL transactions in an INIT_TXN environment.
Does not deal with NULL txn cursors yet.
Also adds DB_AUTO_COMMIT
