Announcement: New release candidate of MonetDB suite
by Sjoerd Mullender 14 Jun '16

14 Jun '16

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 This is a heads up announcement. We at CWI and MonetDB have prepared a release candidate for the Jun2016 release. Usually we just foist a new release upon you, our unsuspecting users, but this time, because there are so many changes, we thought it better to give you a little warning. See http://dev.monetdb.org/downloads/testing/ for the release and the preliminary release notes [1]. Among the changes is a complete overhaul of the MonetDB-geom module. If you use that, make very sure you have your backups in order. Also note that since this new version depends on an up-to-date version of the geos library, there is no geom module available for older Linux releases (in particular, Debian 7 (wheezy), Ubuntu 12.04 LTS (Precise Pangolin) and Ubuntu 14.04 LTS (Trusty Tahr), and RedHat Enterprise Linux (CentOS and Scientific Linux) 6). The plan is to turn this release candidate into an actual release before the end of this month (June 2016). If you find a bug in this release candidate, please let us know on the bug tracker [2]. We will then determine whether to go ahead with the release (and hopefully fix the bug in the next bug-fix release) or postpone the release and fix the bug first.

The MonetDB team at CWI/MonetDB BV is pleased to announce the Jul2015 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/>. Jul 2015 feature release MonetDB5 Server * Implemented batcalc.min and batcalc.max. Made calc.min and calc.max generic so that no other implementations are needed. * Removed function batcalc.ifthen. Build Environment * Upgraded the license to the Mozilla Public License Version 2.0. Client Package * Added a new output format to mclient: --format=expanded (or -fx). In this format, column values are shown in full and below each other. MonetDB Common * BUNtvar and BUNhvar macros no longer work for TYPE_void columns. * Changed interfaces of a lot of GDK-level functions. When they modify a BAT, don't return the same BAT or NULL, but instead return GDK_SUCCEED or GDK_FAIL. * Changed a bunch of hash-related functions to work on the tail column. The functions that have been changed to work on the tail column are: BAThash, BATprepareHash, HASHgonebad, HASHins, and HASHremove. Java Module * Improved JDBC driver to not throw NullPointerException anymore when calling isNullable() or getPrecision() or getScale() or getColumnDisplaySize() or getSchemaName() or getTableName() or getColumnClassName() on a ResultSetMetaData object. * We now compile the Java classes using the latest Java 1.8 version, and we tell it to compile for Java 1.7. SQL * Differences between time, timestamp, and date values now return properly typed interval types (second or month intervals) instead of integers. * Added support for 128-bit integers (called HUGEINT) on platforms that support this. * Removed support for the mseed library. * Removed support for RDF. * Removed DataCell. It was experimental code that was never enabled. Bug Fixes * 2618: Implement master slave scheme * 3361: constants as MAL function parameters prevent intermediate reuse * 3364: Cannot set role back to a user's default role * 3365: Unable to grant object privileges while having a non-default current_role * 3440: Sequence type errors * 3449: mserver crash on start - Freebsd 10 amd64 * 3476: Cannot revoke object access * 3496: autocompletion table names does not work correctly * 3556: when 2 multiplexed functions in MAL plan, only one is mapped correctly to bat<mod>.function primitive * 3564: Request: add support for postgresql specific scalar function: split_part(string text, delimiter text, field int) * 3625: SIGSEGV because mat array can overrun in opt_mergetable.c * 3627: SQRT in CASE does not work as of Oct2014 * 3654: configure --enable-fits requires extra commands after creating a database instance * 3673: mclient 'expanded' row formatter * 3674: Obfuscate event tracing * 3679: No error is given when incorrect timezone value is specified for a timetz column * 3686: Wrong associativity of multiply/divide * 3702: Filter function not found if created in a user schema * 3708: wrong scoping for cross-schema view references * 3716: alter table my_merge_table drop table t1; crashes mserver5 with Segmentation fault * 3724: Wrong size calculation in BATsubjoin * 3730: SAMPLE function not sampling randomly * 3732: memory leak (of InstrRecord) in opt_mergetable * 3733: "(TRUE OR <Exp>) AND <Exp>" is evaluated incorrectly * 3735: python connection with unix_socket * 3736: crash if mclient disconnects abruptly during a query * 3738: Database inconsistency when using savepoint * 3739: CASE statements do not handle NULLs in the IN () operator properly * 3740: select epoch(now()); types timestamptz(7,0) and bigint(64,0) are not equal * 3742: Division By Zero * 3744: cast to int gives different results for decimal than double * 3747: joins fail in the presence of nulls * 3748: Missing META-INF/services/java.sql.Driver in JDBC package * 3753: Hang on json field parsing * 3754: select from a REMOTE TABLE referring local table crashes mserver5 * 3756: column type conversion sticks to subsequent queries * 3758: "COPY INTO ..." doesn't work, if executing from 2 processes concurrently. * 3759: select data from "sys"."rejects" returns unexpected error and when next select data from "sys"."sessions" causes an assertion failure in mal_interpreter.c:646. * 3760: SQL parser has problem with (position of) a scalar subquery in a SELECT-list * 3761: SQL executor has problem with (position of) a subquery in a SELECT-list.

29 Jan '15

The MonetDB team at CWI/MonetDB BV is pleased to announce the Oct2014-SP2 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/>. Oct 2014-SP2 bugfix release Client Package * Changes to the Perl interface, thanks to Stefan O'Rear: 1. removes "use sigtrap", because this has global effects and should not be used by modules, only by the application. 2. allows Perl 5.8.1+ Unicode strings to be passed to quote() and included in statements (UTF-8 encoded, as expected by Monet's str module) 3. quote and unquote now use the same quoting rules as the MonetDB server, allowing for all characters except NUL to be round-tripped 4. several character loops have been reimplemented in regex for much greater performance 5. micro-optimizations to the result fetch loop 6. block boundaries are preserved in piggyback data so that Xclose is not appended or prepended to a SQL command 7. diagnostic messages #foo before a result header are ignored, this is necessary to use recycler_pipe 8. fail quickly and loudly if we receive a continuation prompt (or any other response that starts with a non-ASCII character) 9. header lines must start with %, not merely contain %, fixing a bug when querying a table where string values contain % 10. after closing a large resultset, account for the fact that a reply will come and do not lose sync 11. allow a MAPI_TRACE environment variable to dump wire protocol frames to standard output 12. fixes maximum MAPI block size to match the server limit of 16k. previously would crash on blocks larger than 16k SQL * Fixed a typo in a column name of the sys.tablestoragemodel view (auxillary changed to auxiliary). Bug Fixes * 3467: Field aliases with '#' character excise field names in result set. * 3605: relational query without result * 3619: Missing dll on MonetDB Start * 3622: Type resolution error * 3624: insert of incomplete or invalid ip address values in inet column is silently accepted but the values are not stored (they become/show nil) * 3626: casting a type without alias results in program contains errors * 3628: mclient and ODBC driver report 'type mismatch' when stddev_pop used in a select which returns 0 rows * 3629: IF THEN ELSEIF always evaluates the first test as true * 3630: segv on rel_order_by_column_exp * 3632: running make clean twice gives an error in clients/ruby/adapter * 3633: Wrong result for HAVING with floating-point constant * 3640: Missing implementation of scalar function: sql_sub(<date>, <month interval>) * 3641: SQL lexer fails to detect string end if it the last character is U+FEFF ZERO WIDTH NO-BREAK SPACE * 3642: Combined WHERE conditions less-than plus equals-to produce incorrect results * 3643: Missing implementations of scalar function: sql_sub(<timetz>, arg2) * 3644: COPY INTO fails to import "inet" data type when value has prefix length in CIDR notation * 3646: ORDER BY clause does not produce proper results on 'inet' datatype * 3649: recycler crashes with concurrent transactions
