A table can be partitioned by files, this is an enhanced MULTIPLE table. It can be also partitioned by sub-tables like TBL and this enables table sharding. 2) Handling a CONNECT bug that causes in some cases extraneous rows to remain in the table after an UPDATE or DELETE when the command uses indexing (for not fixed file tables). Until a real fix is done, CONNECT tries to ignore indexing and if it cannot do it abort the command with an error message. - Add tests on partitioning added: storage/connect/mysql-test/connect/r/part_file.result storage/connect/mysql-test/connect/r/part_table.result storage/connect/mysql-test/connect/t/part_file.test storage/connect/mysql-test/connect/t/part_table.test - Temporary fix modified: sql/sql_partition.cc - Add partition support modified: storage/connect/ha_connect.cc storage/connect/ha_connect.h storage/connect/reldef.cpp storage/connect/reldef.h storage/connect/tabdos.cpp - Add functions ha_connect::IsUnique and ha_connect::CheckColumnList modified: storage/connect/ha_connect.cc storage/connect/ha_connect.h - Prevent updating a partition table column that is part of the partition function (outward tables only) modified: storage/connect/ha_connect.cc - Support INSERT/UPDATE/DELETE for PROXY tables modified: storage/connect/tabutil.cpp - Handle the bug on updating rows via indexing.

It was developed in a sub-branch of this one and merged by pushing all the changes from it. This version adds the following to CONNECT: - MRR support (similar to the MyISAM one) - Block, Remote and dynamic indexing - Partitioning support (using the PARTITION engine) Here is a list of the commited changes made in the sub-branch: ======================================================================== ------------------------------------------------------------ revno: 4009 committer: Olivier Bertrand branch nick: 10.0-connect timestamp: Thu 2014-07-17 18:13:51 +0200 message: This commit brings many changes, in particular two important ones: 1) Support of partitioning by connect. A table can be partitioned by files, this is an enhanced MULTIPLE table. It can be also partitioned by sub-tables like TBL and this enables table sharding. 2) Handling a CONNECT bug that causes in some cases extraneous rows to remain in the table after an UPDATE or DELETE when the command uses indexing (for not fixed file tables). Until a real fix is done, CONNECT tries to ignore indexing and if it cannot do it abort the command with an error message. - Add tests on partitioning added: storage/connect/mysql-test/connect/r/part_file.result storage/connect/mysql-test/connect/r/part_table.result storage/connect/mysql-test/connect/t/part_file.test storage/connect/mysql-test/connect/t/part_table.test - Temporary fix modified: sql/sql_partition.cc - Add partition support modified: storage/connect/ha_connect.cc storage/connect/ha_connect.h storage/connect/reldef.cpp storage/connect/reldef.h storage/connect/tabdos.cpp - Add functions ha_connect::IsUnique and ha_connect::CheckColumnList modified: storage/connect/ha_connect.cc storage/connect/ha_connect.h - Prevent updating a partition table column that is part of the partition function (outward tables only) modified: storage/connect/ha_connect.cc - Support INSERT/UPDATE/DELETE for PROXY tables modified: storage/connect/tabutil.cpp - Handle the bug on updating rows via indexing.

Firstly a new value is stored in indexes to know if they are sorted, preventing to do the sorting when it is not needed. Secondly, almost all in now done in connect instead of being done by the different file access method classes. This pepares the future use of temporary files for all table types and also fix the bug that was occuring when partially using a multi-column index because of false MRR like call of position followed by unsorted rnd_pos no more using indexing. modified: storage/connect/connect.cc storage/connect/filamap.cpp storage/connect/filamap.h storage/connect/filamdbf.cpp storage/connect/filamdbf.h storage/connect/filamfix.cpp storage/connect/filamfix.h storage/connect/filamtxt.cpp storage/connect/filamtxt.h storage/connect/filamvct.cpp storage/connect/filamvct.h storage/connect/tabdos.cpp storage/connect/tabdos.h storage/connect/tabfix.h storage/connect/tabfmt.cpp storage/connect/tabfmt.h storage/connect/xindex.cpp storage/connect/xindex.h storage/connect/xtable.h --- storage/connect/connect.cc | 71 +++++--- storage/connect/filamap.cpp | 85 +++------- storage/connect/filamap.h | 5 +- storage/connect/filamdbf.cpp | 36 +++- storage/connect/filamdbf.h | 5 +- storage/connect/filamfix.cpp | 155 ++---------------- storage/connect/filamfix.h | 4 +- storage/connect/filamtxt.cpp | 364 +++++++++++++++++++---------------------- storage/connect/filamtxt.h | 17 +- storage/connect/filamvct.cpp | 278 ++----------------------------- storage/connect/filamvct.h | 4 - storage/connect/tabdos.cpp | 30 +++- storage/connect/tabdos.h | 3 + storage/connect/tabfix.h | 2 + storage/connect/tabfmt.cpp | 18 +- storage/connect/tabfmt.h | 381 ++++++++++++++++++++++--------------------- storage/connect/xindex.cpp | 40 +++-- storage/connect/xindex.h | 1 + storage/connect/xtable.h | 5 + 19 files changed, 591 insertions(+), 913 deletions(-) (limited to 'storage/connect') diff --git a/storage/connect/connect.cc b/storage/connect/connect.cc index e495a0f62b9..a458c0e0c5a 100644 --- a/storage/connect/connect.cc +++ b/storage/connect/connect.cc @@ -479,7 +479,7 @@ RCODE CntReadNext(PGLOBAL g, PTDB tdbp) /***********************************************************************/ RCODE CntWriteRow(PGLOBAL g, PTDB tdbp) { - RCODE rc; + RCODE rc; PCOL colp; PTDBASE tp= (PTDBASE)tdbp; @@ -503,11 +503,14 @@ RCODE CntWriteRow(PGLOBAL g, PTDB tdbp) if (!colp->GetColUse(U_VIRTUAL)) colp->WriteColumn(g); -// if (tdbp->GetMode() == MODE_INSERT) -// tbxp->SetModified(true); - - // Return result code from write operation - rc= (RCODE)tdbp->WriteDB(g); +//if (tp->GetMode() == MODE_UPDATE && tp->IsUsingTemp(g) && +// tp->GetKindex() && !tp->GetKindex()->IsSorted()) + if (tp->IsIndexed()) + // Index values must be sorted before updating + rc= (RCODE)((PTDBDOS)tp)->GetTxfp()->StoreValues(g, true); + else + // Return result code from write operation + rc= (RCODE)tdbp->WriteDB(g); err: g->jump_level--; @@ -517,7 +520,7 @@ RCODE CntWriteRow(PGLOBAL g, PTDB tdbp) /***********************************************************************/ /* UpdateRow: Update a row into a table. */ /***********************************************************************/ -RCODE CntUpdateRow(PGLOBAL g, PTDB tdbp) +RCODE CntUpdateRow(PGLOBAL g, PTDB tdbp) { if (!tdbp || tdbp->GetMode() != MODE_UPDATE) return RC_FX; @@ -531,19 +534,28 @@ RCODE CntUpdateRow(PGLOBAL g, PTDB tdbp) /***********************************************************************/ RCODE CntDeleteRow(PGLOBAL g, PTDB tdbp, bool all) { - RCODE rc; + RCODE rc; + PTDBASE tp= (PTDBASE)tdbp; if (!tdbp || tdbp->GetMode() != MODE_DELETE) return RC_FX; else if (tdbp->IsReadOnly()) return RC_NF; - if (((PTDBASE)tdbp)->GetDef()->Indexable() && all) - ((PTDBDOS)tdbp)->Cardinal= 0; + if (all) { + if (((PTDBASE)tdbp)->GetDef()->Indexable()) + ((PTDBDOS)tdbp)->Cardinal= 0; + + // Note: if all, this call will be done when closing the table + rc= (RCODE)tdbp->DeleteDB(g, RC_FX); +//} else if (tp->GetKindex() && !tp->GetKindex()->IsSorted() && +// tp->Txfp->GetAmType() != TYPE_AM_DBF) { + } else if(tp->IsIndexed()) { + // Index values must be sorted before updating + rc= (RCODE)((PTDBDOS)tp)->GetTxfp()->StoreValues(g, false); + } else // Return result code from delete operation + rc= (RCODE)tdbp->DeleteDB(g, RC_OK); - // Return result code from delete operation - // Note: if all, this call will be done when closing the table - rc= (RCODE)tdbp->DeleteDB(g, (all) ?
