The MonetDB team at CWI/MonetDB BV is pleased to announce the Dec2016-SP4 bugfix release of the MonetDB suite of programs. More information about MonetDB can be found on our website at <http://www.monetdb.org/>. For details on this release, please see the release notes at <http://www.monetdb.org/Downloads/ReleaseNotes>. As usual, the download location is <http://dev.monetdb.org/downloads/>. Dec 2016-SP4 bugfix release MonetDB5 Server * Fixed a bug causing a crash during cleanup when mserver5 is stopped with monetdb stop database. * Some memory leaks were plugged. MonetDB Common * A potential deadlock was fixed in order index creation. * A bug that could happen during recovery of the write-ahead log (WAL) was fixed. See changeset 98ad79c555cc for details. SQL * Some memory leaks were plugged. * Upgrade code was added for an old change in the sys.settimeout function. * A bug was fixed with the automatic "vacuum" operation on system tables. Bug Fixes * 6110: cast of a SQL boolean value to a string or clob or (var)char is wrong * 6254: Crash (and assertion failure) after querying a view which uses a correlated subquery in the select-list * 6256: Assertion Trigger on FULL OUTER JOIN with more than two BETWEEN clauses * 6257: wrong count values (1 instead of 0) for correlated aggregation queries * 6258: Vulnerability in FITS and NETCDF data vaults * 6259: crash on select query from sqlitelogictests * 6260: Sqlitelogictest crash * 6288: Function cannot find column in merge table * 6295: msqldump writes unescaped timestamp values when using inserts

The MonetDB team at CWI/MonetDB BV is pleased to announce the Dec2016-SP3 bugfix release of the MonetDB suite of programs. More information about MonetDB can be found on our website at <http://www.monetdb.org/>. For details on this release, please see the release notes at <http://www.monetdb.org/Downloads/ReleaseNotes>. As usual, the download location is <http://dev.monetdb.org/downloads/>. Dec 2016-SP3 bugfix release MonetDB Common * Fixed a bug when appending string bats that are fully duplicate eliminated. It could happend that the to-be-appended bat had an empty string at an offset and at that same offset in the to-be-appended-to bat there happened to be a (sequence of) NULL(s). Then this offset would be used, even though it might nog be the right offset for the empty string in the to-be-appended-to bat. This would result in multiple offsets for the empty string, breaking the promise of being duplicate eliminated. Bug Fixes * 6138: Weak duplicate elimination in string heaps > 64KB * 6183: ResultSet returns double quoted column name if name contains space characters * 6216: Assertion raised (sqlsmith) * 6219: Crash in rel_optimizer (sqlsmith) * 6227: Monetdb fails on remote tables * 6228: mclient crashes if real column is multiplied by it itself * 6229: ANALYZE, unexpected end of input * 6230: ANALYZE, syntax error * 6237: semijoin with empty right bat does not return immediately * 6242: Crash on rel_reduce_groupby_exps (sqlsmith) * 6243: Static optimization gives wrong result (1 + NULL = -127) * 6245: Nested query crashes all versions of MonetDB or gives wrong result starting from Dec2016-SP2 * 6246: update statements: references to a table do not bind to its alias * 6247: Type analysis issue (sqlsmith) * 6248: update statements: the semantic stage does not resolve the relation in the from clause * 6250: Assertion failure when querying a Blob column with order by DESC * 6251: Crash after adding an ordered index on sys.statistics column and querying sys.statistics * 6253: FITS Data Vaults does not work when using user/pw and other than sys schema name

21 Dec '16

The MonetDB team at CWI/MonetDB BV is pleased to announce the Dec2016 feature release of the MonetDB suite of programs. More information about MonetDB can be found on our website at <http://www.monetdb.org/>. For details on this release, please see the release notes at <http://www.monetdb.org/Downloads/ReleaseNotes>. As usual, the download location is <http://dev.monetdb.org/downloads/>. Dec 2016 feature release MonetDB5 Server * Removed the zorder module with functions zorder.encode, zorder.decode_x and zorder.decode_y. * Removed command bbp.getHeat(). * Removed bat.setColumn with two arguments and bat.setRole. Use bat.setColumn with one argument instead. * Removed function BKCappend_reverse_val_wrap: it was unused. * The "wrd" type has been removed from GDK and MAL. The type was defined to be a 32 bit integer on 32 bit architectures and a 64 bit integer on 64 bit architectures. We now generally use "lng" (always 64 bits) where "wrd" was used. * Keep a collection of full traces. Each time the SQL user applies the TRACE option, the full json trace is retained within the <dbpath>/<dbname>/sql_traces Build Environment * New packages MonetDB-python2 (Fedora) and monetdb-python2 (Debian/Ubuntu) have been created for Python 2 integration into MonetDB. * With OID size equal to ABI/word size, mserver5 does not need to print the OID size, anymore. * Removed obsolete code associated with long gone static linking option. * Removed configure option --enable-oid32 to compile with 32 bit OIDs on a 64 bit architecture. . * The Perl, PHP, and Python clients, and the JDBC driver each now have their own repositories and release cycles. The Python client is maintained by Gijs Molenaar on Github (https://github.com/gijzelaerr/pymonetdb) the other clients are maintained by CWI/MonetDB on our own server (https://dev.monetdb.org/hg/monetdb-java, https://dev.monetdb.org/hg/monetdb-perl, https://dev.monetdb.org/hg/monetdb-php) MonetDB Common * The tnokey values must now be 0 if it is not known whether all values in a column are distinct. * The 2-bit tkey field in the bat descriptor has been split into two single bit fields: tkey and tunique. The old tkey&BOUND2BTRUE value is now stored in tunique. * Implemented conversion to str from any type (not just the internal types). * VALcopy and VALinit both return their first argument on success or (and that's new) NULL on (allocation) failure. * BATattach now can also create a str BAT from a file consisting of null-terminated strings. The input file must be encoded using UTF-8. * BATattach now copies the input file instead of "stealing" it. * Removed the lastused "timestamp" from the BBP. * Removed batStamp field from BAT descriptor, and removed the BBPcurstamp function. * Removed unused functions BBPhot and BBPcold. * Removed BATderiveTailProps and BATderiveProps. Just set the properties you know about, or use BATsettrivprop. * Removed the macro BUNfirst. It can be replaced by 0. * Changed BATroles by removing the argument to set the name of the head column. * The head column is now completely gone. MonetDB is completely "headless". * The format of the BBP.dir file was simplified. Since the head column is VOID, the only value that needs to be stored is the head seqbase. * BATs now only have a single (logical) name. * The function BATmirror is gone. The HEAD column is always VOID (with a non-nil seqbase) and the TAIL column carries the data. All functions that deal with data work on the TAIL column. * BATkey now works on the TAIL column instead of the HEAD column. * Replaced BATseqbase with BAThseqbase and BATtseqbase, the former for setting the seqbase on the HEAD, the latter for setting the seqbase on the TAIL. * Replaced function BATnew with COLnew with slightly different arguments: the first argument of COLnew is the SEQBASE of the head column (which is always VOID). * The "wrd" type has been removed from GDK and MAL. The type was defined to be a 32 bit integer on 32 bit architectures and a 64 bit integer on 64 bit architectures. We now generally use "lng" (always 64 bits) where "wrd" was used. SQL * Removed functions sys.zorder_encode, sys.zorder_decode_x, and sys.zorder_decode_y. * The experimental recycler code is moved to the attic. * The syntax of bat.new(:oid,:any) has been changed by dropping the superflous :oid. All BATs are now binary associations between a void column and a materialized value column. (except for the internal :bat[:void,:void] representation of simple oid ranged tails.) Bug Fixes * 3357: Implement setQueryTimeout() * 3445: Add support for database name to dotmonetdb file * 3597: SQL to MAL listing looses types * 3973: JDBC hangs * 3976: Performance enhancement to LIKE without wildcards * 4005: Correlated update causes incorrect null constraint violation * 4016: merge table only optimises for point query * 4040: sys.storage call can take a long time * 4047: Segfault when updating a dropped table * 4050: Database corruption when running low on inode * 4057: missing bulk operations between constant and bat * 4061: SIGSEGV in candscan_lng * 4066: Deadlocked monetdbd * 6068: Error message about incompatible BBP version should be clearer * 6069: query with union all silently crashes * 6070: setting negative session query timeout should not be possible/allowed * 6071: where clause with cast and floor fails to sigsegv * 6072: Bind to UPD delta column does not get/show type information in EXPLAIN * 6073: Missing type information for constants in MAL explain * 6074: SET ROLE command does not work * 6075: gdk_calc.c:13113: BATcalcifthenelse_intern: Assertion `col2 != NULL' failed. * 6076: rel_optimizer.c:5426: rel_push_project_up: Assertion `e' failed. * 6077: mserver5: rel_optimizer.c:5444: rel_push_project_up: Assertion `e' failed. * 6078: rel_bin.c:2402: rel2bin_project: Assertion `0' failed. * 6084: Merge table point to wrong columns if columns in partition tables are deleted * 6108: monetdb5-sql sysv init script does not wait for shutdown * 6114: segfault raised in the query rewriter due to a null pointer * 6115: Assertion hit in the codegen * 6116: Codegen does not support certain kind of selects on scalar subqueries * 6117: Assertion hit in the query rewriting stage during the push down phase * 6118: SIGSEGV in strPut due to shared heap * 6119: Assertion hit in the MAL optimiser on a complex query * 6120: QUANTILE() treats NULL as if it is zero * 6121: SELECT a.col IN ( b.col FROM b ) FROM a statements with no error but no result * 6123: Assertion hit in the codegen #2 * 6124: CASE <column> WHEN NULL THEN 0 ELSE 1 END returns wrong result * 6125: Stack overflow in the query rewriter with a query having an OR condition and a nested SELECT subexpression * 6126: batcalc.== can't handle void BATs * 6139: Debian libmonetdb13 conflicts with libmonetdb5-server-geom

More information about MonetDB can be found on our website at <http://www.monetdb.org/>. For details on this release, please see the release notes at <http://www.monetdb.org/Downloads/ReleaseNotes>. As usual, the download location is <http://dev.monetdb.org/downloads/>. Jun 2016-SP1 bugfix release . * Lots of memory leaks have been plugged across the whole system. Java Module * Corrected PROCEDURE_TYPE output value of method DatabaseMetaData.getProcedures(). It used to return procedureReturnsResult. Now it returns procedureNoResult. Corrected ORDINAL_POSITION output value of method DatabaseMetaData.getProcedureColumns(). It used to start with 0, but as procedures do not return a result value it now starts with 1 for all the procedure arguments, as defined by the JDBC API. * Improved output of method DatabaseMetaData.getProcedures(). The REMARKS column now contains the procedure definition as stored in sys.functions.func. The SPECIFIC_NAME column now contains the procedure unique identifier as stored in sys.functions.id. This allows the caller to retrieve the specific overloaded procedure which has the same name, but different arguments. Also improved output of method DatabaseMetaData.getProcedureColumns(). The SPECIFIC_NAME column now contains the procedure unique identifier as stored in sys.functions.id. This allows the caller to retrieve the proper arguments of the specific overloaded procedure by matching the SPECIFIC_NAME value. * Improved output of method DatabaseMetaData.getFunctions(). The REMARKS column now contains the function definition as stored in sys.functions.func. The SPECIFIC_NAME column now contains the function unique identifier as stored in sys.functions.id. This allows the caller to retrieve the specific overloaded function which has the same name, but different arguments. Also improved output of method DatabaseMetaData.getFunctionColumns(). The SPECIFIC_NAME column now contains the function unique identifier as stored in sys.functions.id. This allows the caller to retrieve the proper arguments of the specific overloaded function by matching the SPECIFIC_NAME value. Bug Fixes * 4014: KILL signal * 4021: Analyze query does not escape input [security] * 4026: JDBC driver incorrectly converts TINYINT fields to String instead of an integer type. * 4028: inputs not the same size * 4031: mclient doesn't accept - argument to refer to stdin * 4032: no decimal places after update. ODBC driver * 4035: SQL Function call bug * 4036: Possible sql_catalog corruption due to unclean backuped tail

The MonetDB team at CWI/MonetDB BV is pleased to announce the Jun2016 feature release of the MonetDB suite of programs. More information about MonetDB can be found on our website at <http://www.monetdb.org/>. For details on this release, please see the release notes at <http://www.monetdb.org/Downloads/ReleaseNotes>. As usual, the download location is <http://dev.monetdb.org/downloads/>. Jun 2016 feature release MonetDB5 Server * Extended the storage() table producing function to also accept storage([schemaname [, tablename [, columnname]]]) * The :bat[:oid,:any] type descriptor has been turned into its columnar version :bat[:any] * Converted the *.mal scripts into *.malC versions to prepare for removal of the mserver console. * Removed functions mat.hasMoreElements, mat.info, mat.mergepack, mat. newIterator, mat.project, mat.pack2, mat.sortReverse, mat.sort, and mat.slice. * Removed grouped aggregate functions from the aggr module in which the groups were indicated by the head column of the bat to be aggregated. Use the interface with a separate group bat instead. * The server now stops executing a query when the client disconnects. * Removed algebra.join. Use algebra.subjoin instead. * Removed algebra.antijoin. Use algebra.subantijoin or algebra.subthetajoin instead. * The MAL function 'leftfetchjoin' is renamed to its relational algebra version 'projection' * The generic property handling scheme has been removed. It was used in just a few places, for widely different purposes and contained cruft. * Removed functions str.iconv and str.codeset. Internally, strings are always in UTF-8 encoding, so we can't allow code set conversions. * Removed algebra.like with a BAT argument. Use algebra.likesubselect instead. * Removed algebra.leftjoin. Use algebra.subleftjoin or algebra.leftfetchjoin instead. * Removed algebra.tdiff and algebra.tinter. * Removed algebra.sample. Use sample.subuniform instead. * Removed algebra.select. Use algebra.subselect instead. * Removed algebra.revert. * Removed bat.order and bat.orderReverse functions. * Changed client.getUsers to return two bats, one with the user id and one with the user name. * Implemented algebra.subdiff and algebra.subinter. * Removed algebra.tdifference and algebra.tintersect. * Removed algebra.tunion. Build Environment * A new package MonetDB-lidar (Fedora) or libmonetdb5-server-lidar (Debian/Ubuntu) has been created to work with LiDAR data. * Implemented a systemd configuration file for a monetdbd.service on systems that support it (Fedora, newer Ubuntu). Client Package * The Ruby client is now in a separate repository (http://dev.monetdb.org/hg/monetdb-ruby) and released independently. Geom Module * The geom module has been completely overhauled. Types are now specified as GEOMETRY(POINT) instead of POINT, old functions have been removed, new ones introduced. However, even with all the changes, a database upgrade should still be possible (as always, make a backup first). MonetDB Common * Removed BATconst. Use BATconstant instead. * Changed BATconstant. It now has a new first argument with the seqbase for the head column. * Removed BATmmap. It was no longer used. * BUNdelete and BATdel don't accept a foce argument and only allow deleting values that have not yet been committed. BUNdelete exchanges the deleted value with the last value (if the deleted value isn't the last value). BATdel compacts the BAT by shifting values after the deleted values up. The list of to-be-deleted values in BATdel must be sorted and unique. * Removed BUNreplace from list of exported functions. It wasn't used, and there is still BUNinplace and void_inplace that do more-or-less the same thing. * Changed BATderiveHeadProps to BATderiveTailProps (and it now works on the tail column). * Removed unused functions BATalpha, BATdelta, and BATprev. * Removed function VIEWcombine. Use BATdense instead. * Removed "left" parameter from BUNinplace. It wasn't used since the BAT it works on is dense headed. * Created function BATdense to easily create a [void,void] BAT with specified seqbases for head and tail and a count. * Removed function BATmark. When all head columns are dense, BATmark basically only created a new [void,void] BAT. * Renamed BATsubsort to BATsort. * Removed "sub" from the names of the function BATsubselect, BATthetasubselect, BATsubcross, BATsubleftjoin, BATsubouterjoin, BATsubthetajoin, BATsubsemijoin, BATsubdiff, BATsubjoin, BATsubbandjoin, BATsubrangejoin, and BATsubunique. * Removed BATsubleftfetchjoin: it was not used. * Removed BATcross1. Use BATsubcross instead. * Removed all versions of the SORTloop macro. * Removed Batkdiff. Use BATsubdiff instead. * Removed BATselect. Use BATsubselect instead. * Removed BATsemijoin. Use BATsubsemijoin instead. * Removed BATjoin. Use BATsubjoin instead. * Removed BATleftjoin. Use BATsubleftjoin or BATproject instead. * Removed BATleftfetchjoin. Use BATproject instead. * Removed BUNins from the list of exported functions. * Removed legacy functions BATuselect and BATuselect_. * Removed legacy functions BATantijoin, BATbandjoin, BATouterjoin, BATrangejoin, and BATthetajoin. * Removed function BATrevert. * BATordered now works on the TAIL column. * Removed obsolete functions BATorder() and BATorder_rev(). * Implemented BATsubdiff which returns a list of OIDs (sorted, i.e. usable as candidate list) of tuples in the left input whose value does not occur in the right input. * Removed function BATkintersect. It wasn't used anymore. It's functionality can be obtained by using BATsubsemijoin. * Removed the function BATkunion. Java Module * Fixed problem in DatabaseMetaData.getUDTs() when it was called with types parameter filled. It used to throw SQException with message: SELECT: identifier 'DATA_TYPE' unknown. Now it returns the UDTs which match the provided array of data types. * Implemented MonetDatabaseMetaData.supportsConvert() and MonetDatabaseMetaData.supportsConvert(int fromType, int toType) methods. It used to always return false. Now it returns true for the supported conversions. This fixes Bug 3460. * ResultSet.setFetchSize(): added a dummy implementation to get rid of the SQLFeatureNotSupportedException. In MonetDB, it does not make sense to set the fetch size of a result set. If one really wants to set the fetch size, one should use Statement.setFetchSize() instead. * Fixed resource leak in ResultSetMetaData. It created and cached a ResultSet object for each column but never closed the ResultSet objects. * Corrected DatabaseMetaData methods which accept a catalog filter argument. Those methods will now filter the results on the specified catalog name, whereas previously the catalog filter argument was ignored. * Corrected output of column KEY_SEQ of DatabaseMetaData methods: getPrimaryKeys(), getImportedKeys(), getExportedKeys() and getCrossReference(). It now starts at 1 instead of 0 previously. * Corrected DatabaseMetaData.getSchemas() by returning 2 instead of 3 columns. * Improved DatabaseMetaData.getColumns() by returning two additional columns: IS_AUTOINCREMENT and IS_GENERATEDCOLUMN. * Improved DatabaseMetaData.getTypeInfo(). It now returns better information on LITERAL_PREFIX, LITERAL_SUFFIX, CREATE_PARAMS, CASE_SENSITIVE, FIXED_PREC_SCALE and MAXIMUM_SCALE for some data types. Also the returned rows are now ordered by DATA_TYPE, TYPE_NAME, PRECISION as required by the specs. Also corrected output column names "searchable" into "SEARCHABLE" and "MAXIMUM SCALE" into "MAXIMUM_SCALE" to match the JDBC specification. * Corrected DatabaseMetaData.getPseudoColumns(). It used to return 12 empty rows. Now it returns no rows as MonetDB does not have pseudo columns. * Implemented method DatabaseMetaData.getClientProperties(). It used to always return a resultset with 4 completely empty rows. It now returns a resultset with the possible connection properties. * Implemented method DatabaseMetaData.getUDTs(). It used to return an empty resultset. Now it returns the User Defined Types such as inet, json, url and uuid. * Corrected the returned table types in DatabaseMetaData.getTableTypes(). It now returns all 10 table types (as stored in sys.table_types) instead of the previously 8 hardcoded table types. For old MonetDB servers which do not have the sys.table_types table, the old behavior is retained. * Implemented methods DatabaseMetadata.getProcedures() and DatabaseMetadata.getProcedureColumns(). They used to return an empty resultset. Now they return the expected Procedures and ProcedureColumns. Also getProcedureColumns() now returns a resultset with all 20 columns instead of 13 columns previously. * Method getFunctionColumns() in DatabaseMetadata used to throw an SQLException: getFunctionColumns(String, String, String, String) is not implemented. This method is now implemented and returns a resultset. * Method getFunctions() in DatabaseMetadata used to throw an SQLException: SELECT: no such column 'functions.sql' This has been corrected. It now returns a resultset as requested. * The resultsets of DatabaseMetadata methods now no longer return a value for the *_CAT columns as MonetDB does not support Catalogs. * Fixed a memory leak in MonetDatabaseMetaData.java for a static cache which kept references to closed Connection objects. * Improved JdbcClient program when presenting query data to console. It used to send an SQL catalog query for each query result column which slowed down the interactive response considerably. These additional SQL catalog queries have been eliminated. * Corrected MonetResultSet.getObject(String columnName). It no longer throws a NullPointerException in cases where internally a MonetVirtualResultSet is used. * Fixed Connection.isValid(): this method should never attempt to close the connection, even if an error has occurred. SQL * Disallow GRANT <some-user> TO <role-or-use>.

Announcement: New Jun2016 Feature release of MonetDB suite
by Sjoerd Mullender 23 Jun '16

23 Jun '16

The MonetDB team at CWI/MonetDB BV is pleased to announce the Jun2016 feature release of the MonetDB suite of programs. More information about MonetDB can be found on our website at <http://www.monetdb.org/>. For details on this release, please see the release notes at <http://www.monetdb.org/Downloads/ReleaseNotes>. As usual, the download location is <http://dev.monetdb.org/downloads/>. Jun 2016 feature release MonetDB5 Server * Extended the storage() table producing function to also accept storage([schemaname [, tablename [, columnname]]]) * The :bat[:oid,:any] type descriptor has been turned into its columnar version :bat[:any] * Converted the *.mal scripts into *.malC versions to prepare for removal of the mserver console. * Removed functions mat.hasMoreElements, mat.info, mat.mergepack, mat. newIterator, mat.project, mat.pack2, mat.sortReverse, mat.sort, and mat.slice. * Removed grouped aggregate functions from the aggr module in which the groups were indicated by the head column of the bat to be aggregated. Use the interface with a separate group bat instead. * The server now stops executing a query when the client disconnects. * Removed algebra.join. Use algebra.subjoin instead. * Removed algebra.antijoin. Use algebra.subantijoin or algebra.subthetajoin instead. * The MAL function 'leftfetchjoin' is renamed to its relational algebra version 'projection' * The generic property handling scheme has been removed. It was used in just a few places, for widely different purposes and contained cruft. * Removed functions str.iconv and str.codeset. Internally, strings are always in UTF-8 encoding, so we can't allow code set conversions. * Removed algebra.like with a BAT argument. Use algebra.likesubselect instead. * Removed algebra.leftjoin. Use algebra.subleftjoin or algebra.leftfetchjoin instead. * Removed algebra.tdiff and algebra.tinter. * Removed algebra.sample. Use sample.subuniform instead. * Removed algebra.select. Use algebra.subselect instead. * Removed algebra.revert. * Removed bat.order and bat.orderReverse functions. * Changed client.getUsers to return two bats, one with the user id and one with the user name. * Implemented algebra.subdiff and algebra.subinter. * Removed algebra.tdifference and algebra.tintersect. * Removed algebra.tunion. Build Environment * A new package MonetDB-lidar (Fedora) or libmonetdb5-server-lidar (Debian/Ubuntu) has been created to work with LiDAR data. * Implemented a systemd configuration file for a monetdbd.service on systems that support it (Fedora, newer Ubuntu). Client Package * The Ruby client is now in a separate repository (http://dev.monetdb.org/hg/monetdb-ruby) and released independently. Geom Module * The geom module has been completely overhauled. Types are now specified as GEOMETRY(POINT) instead of POINT, old functions have been removed, new ones introduced. However, even with all the changes, a database upgrade should still be possible (as always, make a backup first). MonetDB Common * Removed BATconst. Use BATconstant instead. * Changed BATconstant. It now has a new first argument with the seqbase for the head column. * Removed BATmmap. It was no longer used. * BUNdelete and BATdel don't accept a foce argument and only allow deleting values that have not yet been committed. BUNdelete exchanges the deleted value with the last value (if the deleted value isn't the last value). BATdel compacts the BAT by shifting values after the deleted values up. The list of to-be-deleted values in BATdel must be sorted and unique. * Removed BUNreplace from list of exported functions. It wasn't used, and there is still BUNinplace and void_inplace that do more-or-less the same thing. * Changed BATderiveHeadProps to BATderiveTailProps (and it now works on the tail column). * Removed unused functions BATalpha, BATdelta, and BATprev. * Removed function VIEWcombine. Use BATdense instead. * Removed "left" parameter from BUNinplace. It wasn't used since the BAT it works on is dense headed. * Created function BATdense to easily create a [void,void] BAT with specified seqbases for head and tail and a count. * Removed function BATmark. When all head columns are dense, BATmark basically only created a new [void,void] BAT. * Renamed BATsubsort to BATsort. * Removed "sub" from the names of the function BATsubselect, BATthetasubselect, BATsubcross, BATsubleftjoin, BATsubouterjoin, BATsubthetajoin, BATsubsemijoin, BATsubdiff, BATsubjoin, BATsubbandjoin, BATsubrangejoin, and BATsubunique. * Removed BATsubleftfetchjoin: it was not used. * Removed BATcross1. Use BATsubcross instead. * Removed all versions of the SORTloop macro. * Removed Batkdiff. Use BATsubdiff instead. * Removed BATselect. Use BATsubselect instead. * Removed BATsemijoin. Use BATsubsemijoin instead. * Removed BATjoin. Use BATsubjoin instead. * Removed BATleftjoin. Use BATsubleftjoin or BATproject instead. * Removed BATleftfetchjoin. Use BATproject instead. * Removed BUNins from the list of exported functions. * Removed legacy functions BATuselect and BATuselect_. * Removed legacy functions BATantijoin, BATbandjoin, BATouterjoin, BATrangejoin, and BATthetajoin. * Removed function BATrevert. * BATordered now works on the TAIL column. * Removed obsolete functions BATorder() and BATorder_rev(). * Implemented BATsubdiff which returns a list of OIDs (sorted, i.e. usable as candidate list) of tuples in the left input whose value does not occur in the right input. * Removed function BATkintersect. It wasn't used anymore. It's functionality can be obtained by using BATsubsemijoin. * Removed the function BATkunion. Java Module * Fixed problem in DatabaseMetaData.getUDTs() when it was called with types parameter filled. It used to throw SQException with message: SELECT: identifier 'DATA_TYPE' unknown. Now it returns the UDTs which match the provided array of data types. * Implemented MonetDatabaseMetaData.supportsConvert() and MonetDatabaseMetaData.supportsConvert(int fromType, int toType) methods. It used to always return false. Now it returns true for the supported conversions. This fixes Bug 3460. * ResultSet.setFetchSize(): added a dummy implementation to get rid of the SQLFeatureNotSupportedException. In MonetDB, it does not make sense to set the fetch size of a result set. If one really wants to set the fetch size, one should use Statement.setFetchSize() instead. * Fixed resource leak in ResultSetMetaData. It created and cached a ResultSet object for each column but never closed the ResultSet objects. * Corrected DatabaseMetaData methods which accept a catalog filter argument. Those methods will now filter the results on the specified catalog name, whereas previously the catalog filter argument was ignored. * Corrected output of column KEY_SEQ of DatabaseMetaData methods: getPrimaryKeys(), getImportedKeys(), getExportedKeys() and getCrossReference(). It now starts at 1 instead of 0 previously. * Corrected DatabaseMetaData.getSchemas() by returning 2 instead of 3 columns. * Improved DatabaseMetaData.getColumns() by returning two additional columns: IS_AUTOINCREMENT and IS_GENERATEDCOLUMN. * Improved DatabaseMetaData.getTypeInfo(). It now returns better information on LITERAL_PREFIX, LITERAL_SUFFIX, CREATE_PARAMS, CASE_SENSITIVE, FIXED_PREC_SCALE and MAXIMUM_SCALE for some data types. Also the returned rows are now ordered by DATA_TYPE, TYPE_NAME, PRECISION as required by the specs. Also corrected output column names "searchable" into "SEARCHABLE" and "MAXIMUM SCALE" into "MAXIMUM_SCALE" to match the JDBC specification. * Corrected DatabaseMetaData.getPseudoColumns(). It used to return 12 empty rows. Now it returns no rows as MonetDB does not have pseudo columns. * Implemented method DatabaseMetaData.getClientProperties(). It used to always return a resultset with 4 completely empty rows. It now returns a resultset with the possible connection properties. * Implemented method DatabaseMetaData.getUDTs(). It used to return an empty resultset. Now it returns the User Defined Types such as inet, json, url and uuid. * Corrected the returned table types in DatabaseMetaData.getTableTypes(). It now returns all 10 table types (as stored in sys.table_types) instead of the previously 8 hardcoded table types. For old MonetDB servers which do not have the sys.table_types table, the old behavior is retained. * Implemented methods DatabaseMetadata.getProcedures() and DatabaseMetadata.getProcedureColumns(). They used to return an empty resultset. Now they return the expected Procedures and ProcedureColumns. Also getProcedureColumns() now returns a resultset with all 20 columns instead of 13 columns previously. * Method getFunctionColumns() in DatabaseMetadata used to throw an SQLException: getFunctionColumns(String, String, String, String) is not implemented. This method is now implemented and returns a resultset. * Method getFunctions() in DatabaseMetadata used to throw an SQLException: SELECT: no such column 'functions.sql' This has been corrected. It now returns a resultset as requested. * The resultsets of DatabaseMetadata methods now no longer return a value for the *_CAT columns as MonetDB does not support Catalogs. * Fixed a memory leak in MonetDatabaseMetaData.java for a static cache which kept references to closed Connection objects. * Improved JdbcClient program when presenting query data to console. It used to send an SQL catalog query for each query result column which slowed down the interactive response considerably. These additional SQL catalog queries have been eliminated. * Corrected MonetResultSet.getObject(String columnName). It no longer throws a NullPointerException in cases where internally a MonetVirtualResultSet is used. * Fixed Connection.isValid(): this method should never attempt to close the connection, even if an error has occurred. SQL * Disallow GRANT <some-user> TO <role-or-use>. Only explicitly created roles can be granted. * Extended grantable schema privileges: when a user is granted the "sysadmin" role, the user now hcan not only create schemas, but also drop schemas. * Introduced COPY INTO/ COPY FROM global privileges. These privileges allows other users than 'monetdb' to be granted the privileges to use the MonetDB bulk data loading/exporting features, i.e., COPY FROM <file> and COPY INTO <file>. Bug Fixes * 2407: Merovingian: allow binds to given ip/interface * 2815: No SRID support * 3361: constants as MAL function parameters prevent intermediate reuse * 3374: UNIQUE constraint does not set tkey property on the corresponding BAT * 3460: incomplete implementation of JDBC driver supportsConvert(), supportsConvert(int fromType, int toType) methods in MonetDatabaseMetaData.java * 3711: JDBC connection using jdbcclient.jar is very slow * 3877: MonetDBLite should allow close then re-open databases? without restarting R * 3911: Invalid connect() call in 'redirect' mode * 3920: query with DISTINCT and correlated scalar subquery in SELECT list causes Assertion failure and crash of mserver5 * 3927: COUNT( distinct my_clob ) , QUANTILE( my_double , number ) fails in dev build * 3956: MonetDBLite unable to execute LIMIT 1 statement * 3972: Drastic Memory leak of 600GBs while generating plan for Query with 25 joins * 3974: Prepared statement rel_bin.c:2378: rel2bin_project: Assertion `0' failed. * 3975: Suspicious code in store_manager() on exit path * 3978: SQL returns TypeException 'aggr.subcorr' undefined for sys.corr function * 3980: JOIN with references on both sides crashes mserver * 3981: Incorrect LEFT JOIN when FROM clause contains nested subqueries * 3983: Creation of a Foreign Key which partially maps to a primary key is accepted without a warning * 3984: Multiple paths in the .profile * 3985: ruby-monetdb-sql gem fails for negative timezone offset (USA, etc.) * 3987: Segfault on malformed csv import * 3991: MonetDBLite feature request: default monetdb.sequential to FALSE on windows * 3994: MonetDBLite dbDisconnect with shutdown=TRUE freezes the console on windows * 3995: NullPointerException when calling getObject() * 3997: calling scalar functions sys.isaUUID(str) or sys.isaUUID(uuid) fail * 3999: length() returns wrong length for strings which have spaces at the end of the string * 4010: RELEASE SAVEPOINT after ALTER TABLE crashes mserver5 * 4011: sys.sessions.user column always shows 'monetdb' * 4013: GDKextendf does not free up memory when it fails due to insufficient resources * 4015: Daemon crashes on database release command
