reintroduce change that saves memcpy when primary key is covering index,
will add note to release notes stating not to have prefix as part of primary key
git-svn-id: file:///svn/mysql/tokudb-engine/src@5068 c7de825b-a66e-492c-adef-691d508d4ae1
add version and capabilities, some cleanup still required, but code works
git-svn-id: file:///svn/mysql/tokudb-engine/src@4929 c7de825b-a66e-492c-adef-691d508d4ae1
remove update_status, at moment, there is nothing that needs updating when
DB is going away
git-svn-id: file:///svn/mysql/tokudb-engine/src@4926 c7de825b-a66e-492c-adef-691d508d4ae1
as of now, no info is stored in status.tokudb because the old info
that was stored is not needed anymore. Info will be stored soon.

remove unused variables share->rows and share->org_rows that were useed
to estimate row count. row count is now estimated with key_range64
git-svn-id: file:///svn/mysql/tokudb-engine/src@4919 c7de825b-a66e-492c-adef-691d508d4ae1
make row count displayed in show table status better by
using key_range64 to estimate stats.records instead of keeping a running tally

temporary change to test if just doing a memcpy will work for unpacking
a Field_new_decimal
real change is to modify Field_new_decimal, but by checking this in, we can
quickly get regression results

just unpacking key has problems when the key is a substring of a column. MySQL still reports that it is a covering index, must back out previous change
git-svn-id: file:///svn/mysql/tokudb-engine/src@4782 c7de825b-a66e-492c-adef-691d508d4ae1
dont unpack entire row when primary key is used as covering index
git-svn-id: file:///svn/mysql/tokudb-engine/src@4770 c7de825b-a66e-492c-adef-691d508d4ae1
back out change for 4591, need more testing before it can go in
reopening ticket

fix buffer overwrite error. Bug has been around, but just recently exposed
by checkin 4590
git-svn-id: file:///svn/mysql/tokudb-engine/src@4616 c7de825b-a66e-492c-adef-691d508d4ae1
implement read_time to take into account that the primary_key is clustered
git-svn-id: file:///svn/mysql/tokudb-engine/src@4595 c7de825b-a66e-492c-adef-691d508d4ae1
pre_acquire table locks from lock tree when mysql is doing a lock table
git-svn-id: file:///svn/mysql/tokudb-engine/src@4591 c7de825b-a66e-492c-adef-691d508d4ae1
rename lock_grabbed to range_lock_grabbed to help distinguish from
cases where table lock is grabbed

fix index_prev in case we don't have lock
it was a typo before
git-svn-id: file:///svn/mysql/tokudb-engine/src@4516 c7de825b-a66e-492c-adef-691d508d4ae1
make handlerton not use a cursor that has had a failed operation
this will be useful for lightweight cursors
git-svn-id: file:///svn/mysql/tokudb-engine/src@4455 c7de825b-a66e-492c-adef-691d508d4ae1
slightly restructure some functions to allow handling of lighter weight cursors
git-svn-id: file:///svn/mysql/tokudb-engine/src@4439 c7de825b-a66e-492c-adef-691d508d4ae1
used to disable covering indexes for some keys with strings for wrong reasons
not anymore
git-svn-id: file:///svn/mysql/tokudb-engine/src@4386 c7de825b-a66e-492c-adef-691d508d4ae1
add instances of read_range_first and read_range_next in ha_tokudb
currently just call parent class version
