Renamed HA_VAR_LENGTH to HA_VAR_LENGTH_PART Renamed in all files FIELD_TYPE_STRING and FIELD_TYPE_VAR_STRING to MYSQL_TYPE_STRING and MYSQL_TYPE_VAR_STRING to make it easy to catch all possible errors Added support for VARCHAR KEYS to heap Removed support for ISAM Now only long VARCHAR columns are changed to TEXT on demand (not CHAR) Internal temporary files can now use fixed length tables if the used VARCHAR columns are short BitKeeper/deleted/.del-ha_isam.cc~4dce65904db2675e: Delete: sql/ha_isam.cc BitKeeper/deleted/.del-_cache.c~b5d80b5c3ae233b1: Delete: isam/_cache.c BitKeeper/deleted/.del-_dbug.c~88d7964ae5e3c9bd: Delete: isam/_dbug.c BitKeeper/deleted/.del-_dynrec.c~48dd758f5a5450df: Delete: isam/_dynrec.c BitKeeper/deleted/.del-_key.c~ce62d47a6c681084: Delete: isam/_key.c BitKeeper/deleted/.del-_locking.c~dea4cdc6ea425c67: Delete: isam/_locking.c BitKeeper/deleted/.del-_packrec.c~47ae1b16c007e9be: Delete: isam/_packrec.c BitKeeper/deleted/.del-_page.c~148b1a613d052ee8: Delete: isam/_page.c BitKeeper/deleted/.del-_search.c~f509292aa1ff18ff: Delete: isam/_search.c BitKeeper/deleted/.del-_statrec.c~58d9263b3475d58b: Delete: isam/_statrec.c BitKeeper/deleted/.del-changed.c~d075de80a314b02d: Delete: isam/changed.c BitKeeper/deleted/.del-close.c~fd62629496ee5bcc: Delete: isam/close.c BitKeeper/deleted/.del-create.c~96cecc433c0c2242: Delete: isam/create.c BitKeeper/deleted/.del-delete.c~65ee8daaa75a14b6: Delete: isam/delete.c BitKeeper/deleted/.del-extra.c~706f29d72beb2565: Delete: isam/extra.c BitKeeper/deleted/.del-info.c~96cfb747af8da0d: Delete: isam/info.c BitKeeper/deleted/.del-isamchk.c~c0f59c2687d2248f: Delete: isam/isamchk.c BitKeeper/deleted/.del-isamlog.c~85b6b31c6e2b8519: Delete: isam/isamlog.c BitKeeper/deleted/.del-log.c~55a973013d55cade: Delete: isam/log.c BitKeeper/deleted/.del-open.c~95b3b75042fae00a: Delete: isam/open.c BitKeeper/deleted/.del-pack_isam.c~43801f0df7504834: Delete: isam/pack_isam.c BitKeeper/deleted/.del-panic.c~f7fd71605324f8f3: Delete: isam/panic.c BitKeeper/deleted/.del-range.c~142f1f8ac4948082: Delete: isam/range.c BitKeeper/deleted/.del-rfirst.c~66f494291dc005d3: Delete: isam/rfirst.c BitKeeper/deleted/.del-rkey.c~cc54c6498352f999: Delete: isam/rkey.c BitKeeper/deleted/.del-rlast.c~d1fe1866139e9866: Delete: isam/rlast.c BitKeeper/deleted/.del-rnext.c~b308eaa1e11ea7de: Delete: isam/rnext.c BitKeeper/deleted/.del-rprev.c~b359f71fdea4bbce: Delete: isam/rprev.c BitKeeper/deleted/.del-rrnd.c~7fcfcce88d4a5200: Delete: isam/rrnd.c BitKeeper/deleted/.del-rsame.c~75a62d5548103a15: Delete: isam/rsame.c BitKeeper/deleted/.del-rsamepos.c~5b5652dd2cda6d5d: Delete: isam/rsamepos.c BitKeeper/deleted/.del-sort.c~e2e56b5a37ce86f4: Delete: isam/sort.c BitKeeper/deleted/.del-static.c~3a1354b84f4a9cc7: Delete: isam/static.c BitKeeper/deleted/.del-test1.c~64d52e9412d457ed: Delete: isam/test1.c BitKeeper/deleted/.del-test2.c~2f9a632cab572958: Delete: isam/test2.c BitKeeper/deleted/.del-test3.c~e8a7a4afe8a087: Delete: isam/test3.c BitKeeper/deleted/.del-isamdef.h~ac8d49e7e2201c66: Delete: isam/isamdef.h BitKeeper/deleted/.del-update.c~670264f51dc44934: Delete: isam/update.c BitKeeper/deleted/.del-write.c~8f1918b1f6770e54: Delete: isam/write.c BitKeeper/deleted/.del-Makefile.am~6cfa0db5e7778d09: Delete: isam/Makefile.am BitKeeper/deleted/.del-make-ccc~3ee55391eda0b0ab: Delete: isam/make-ccc BitKeeper/deleted/.del-ChangeLog~208984fb7a51e568: Delete: isam/ChangeLog BitKeeper/deleted/.del-test_all.res~c2aafb49a3a77db7: Delete: isam/test_all.res BitKeeper/deleted/.del-test_all~93c701e44a9c5b65: Delete: isam/test_all BitKeeper/deleted/.del-.cvsignore~54f6f0f2d5012561: Delete: isam/.cvsignore BitKeeper/deleted/.del-ha_isammrg.cc~dc682e4755d77a2e: Delete: sql/ha_isammrg.cc BitKeeper/deleted/.del-ha_isam.h~bf53d533be3d3927: Delete: sql/ha_isam.h BitKeeper/deleted/.del-ha_isammrg.h~66fd2e5bfe7207dc: Delete: sql/ha_isammrg.h acinclude.m4: Remove ISAM client/mysqldump.c: FIELD_TYPE -> MYSQL_TYPE client/mysqltest.c: Add missing DBUG_RETURN configure.in: Remove ISAM heap/heapdef.h: Add support for VARCHAR heap/hp_create.c: Add support for VARCHAR heap/hp_delete.c: Add support for VARCHAR heap/hp_hash.c: Add support for VARCHAR (VARCHAR keys was not supported before) heap/hp_rkey.c: Add support for VARCHAR heap/hp_update.c: Add support for VARCHAR heap/hp_write.c: Add support for VARCHAR (Added flag SEARCH_UPDATE to mark that this is an update) include/decimal.h: Remove not needed my_global.h include/m_ctype.h: Add support for VARCHAR include/my_base.h: Add support for VARCHAR include/my_handler.h: Moved general purpose macro from MyISAM code include/mysql_com.h: Add support for VARCHAR libmysql/libmysql.c: Add support for VARCHAR libmysqld/Makefile.am: Removed ISAM myisam/ft_static.c: Add support for VARCHAR myisam/ft_test1.c: Add support for VARCHAR myisam/ft_update.c: Add support for VARCHAR myisam/mi_check.c: Add support for VARCHAR myisam/mi_create.c: Add support for VARCHAR -
