Announcement: New Oct2014-SP1 Bugfix release of MonetDB suite
by Sjoerd Mullender 27 Nov '14

27 Nov '14

The MonetDB team at CWI/MonetDB BV is pleased to announce the Oct2014-SP1 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-SP1 bugfix release MonetDB5 Server * Fixed adding of 0 intervals to dates. Build Environment * The libraries included in the Windows installers have been upgraded. We now use libxml2-2.9.2, openssl-1.0.1j, pcre-8.36, and zlib-1.2.8. MonetDB Common * Implemented a change to the way in which string bats are appended. We now try harder to limit the growth of the string heap. * Fixed some problems with BATsample. It was possible for BATsample to return a value that was just beyond the end of the sampled BAT. Also, on some systems the range of the rand() function is rather limited (0..32767) and trying to get a sample larger than this range would result in an infinite loop. SQL * Fixed sys.queue() implementation to report on other queries being executed. * A number of bugs were fixed in the code to upgrade a database from previous releases. This version should fix the upgrade of a database that had been upgraded to the Oct2014 release, but also properly upgrade directly from Jan2014 and Feb2013 releases. Bug Fixes * 3580: cosmetic change (append newline) * 3609: Incorrect use of generate_series * 3611: quantile() and median() commands crash when used 2x on the same variable on a null table * 3612: assertion failure when deleting rows from table to which a FK constraint is defined * 3620: ORDER BY broken when using UNION ALL * 3621: Hexadecimal literal vs decimal literal

Announcement: New Oct2014 Feature release of MonetDB suite
by Sjoerd Mullender 31 Oct '14

31 Oct '14

The MonetDB team at CWI/MonetDB BV is pleased to announce the Oct2014 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/>. Important consideration when upgrading to this release. In this release we have fixed bug 3474. This bug made it possible that there were duplicates despite there being a unique or primary key constraint present. This could only happen for multi-column constraints. MonetDB maintains an internal column containing a hash for multi-column constraints, and there was a bug in the maintenance code of this column. During an upgrade, this column needs to be recreated. This is done by dropping and adding back the constraints. If there are no duplicates, adding back the constrains should work without problem, but if there are duplicates, adding the constraints will fail. There is unfortunately no easy way to tell the user, so after having made the first connection to the server (when the upgrade happens), check the merovingian log (if you use merovingian -- also known as monetdbd) or the server output window (if you don't use merovingian). Jaql support is removed. The experimental code for Jaql support has been removed. If you have RPM or DEB packages for Jaql installed from an earlier version (MonetDB-jaql and monetdb5_jaql respectively), you will need to uninstall them before the upgrade. Known issue when upgrading old versions. We have noticed that upgrading directly from a version older than the Jan2014 release gave an error. Upgrading to Jan2014 first and then on to Oct2014 should work. Backup. As always, make a backup of your databases before upgrading. Oct 2014 feature release MonetDB5 Server * Removed algebra.materialize. * Removed algebra.kunique and algebra.tunique. They were subsumed by algebra.subunique. * Remove algebra.antiuselect and algebra.thetauselect. They were subsumed by algebra.subselect. * Removed algebra.topN and its imlementation BATtopN. The function was not used. * Removed aggr.histogram and its implementation BAThistogram. The function was not used, and did not produce output in the "headless" (i.e. dense-headed) format. Histograms can be created as a by-product of group.subgroup. Build Environment * Jacqueline, the MonetDB/JAQL frontend, has been removed. The frontend never grew beyond being experimental, and there is no interest anymore to maintain the code. Merovingian * monetdb create: add -p flag to set monetdb user password on creation, and therefore allow creating the database in unlocked state mapilib * Changed mapi_timeout argument from seconds to milliseconds. stream * Changed mnstr_settimeout function so that the specified timeout is now in milliseconds (used to be seconds), and that it also needs an extra argument specifying a callback function (no arguments, int result) that should return TRUE if the timeout should cause the function to abort or continue what it was doing. MonetDB Common * Added "multifarm" capability. It is now possible to separate persistent and transient BATs into different directories (presumably on different disks). This can be done by using the --dbextra option of mserver5 (see the man page). SQL * Added PostgreSQL compatible string TRIM, LTRIM, RTRIM, LPAD and RPAD functions * Stop support for upgrading directly from a database created with a server from the Oct2012 release or older. You can upgrade via the Feb2013 or Jan2014 release. Bug Fixes * 2945: evaluation of SQL "between SYMMETRIC" requires MAL iterator because there is no (bulk) MIN/MAX(a,b) * 3204: monetdb create: allow setting admin password during creation * 3390: Missing definition for pushSht in monetdb5/mal/mal_builder.h * 3402: We should have a C implementation of mal.multiplex. * 3422: Segmentation fault after large table insert * 3459: incomplete implementation of JDBC driver getNumericFunctions(), getStringFunctions(), getSystemFunctions(), getTimeDateFunctions(), getSQLKeywords() methods in MonetDatabaseM * 3471: JDBC driver: incorrect output result of SQL query: SELECT 1 ; * 3474: bulk and scalar versions of mkey.rotate_xor_hash differ * 3484: COPY INTO on a file works fine on Linux/OSX, but not on Windows * 3488: Slow SQL execution for correlated scalar subquery * 3489: SQL query with ORDER BY does not order its result as requested * 3490: SQL query kills the mserver5 (Segmentation fault) * 3491: SQL query kills the mserver5 (Segmentation fault) * 3493: Test monetdb5/modules/mal/Tests/pqueue.mal fails since recent checkins * 3494: Tests monetdb5/modules/mal/Tests/pqueue[23].mal lack correct/expected/intended output * 3495: Test sql/test/centipede/Tests/olap.sql lacks correct/expected/intended output * 3497: monetdb start reports crash in merovingian.log * 3498: SQL throws TypeException if aggregations and limit statements are both present * 3502: Database was killed by signal SIGBUS * 3504: COPY INTO does not allow OFFSET without specifying amount of records * 3505: expression with <boolean> = NOT <boolean> returns a syntax error but NOT <boolean> = <boolean> not * 3506: conversion to varchar terminates mserver * 3508: conversion of string '0 ' to type smallint or integer fails * 3510: timestamp + month interval generates bogus MAL? * 3511: When having multiple selections combined with aliases not all of them seem to be evalauted. * 3512: auto-conversion of string to `sht` type no longer works * 3513: COPY BINARY INTO fails on 6gb file; works fine on 3gb * 3516: inserting '0' into a column of datatype numeric fails * 3518: UNION with subqueries * 3521: large results of function exp() are not automatically returned as double * 3522: SQL catalog table sys.columns lists columns for table ids which do not exist in sys.tables * 3523: Window function over union gives no result * 3524: wrong error on missing aggregation column * 3527: select distinct - order by - limit 2 results in one single result * 3528: segfault at mal_session.c:521 * 3532: several geom tests crash after manifold changes * 3534: missing table name with invalid column in join using (and problems after resolving it) * 3536: program contains error with join using integer and smallint * 3542: gdk/gdk_bat.c:2904: BATassertHeadProps: Assertion `!b->H->revsorted || cmp >= 0' failed. * 3543: invalid behavior and incorrect data results for SQL data type: numeric(4,4) * 3544: sys.reuse() corrupts data * 3546: Division by zero in CASE statement that should avoid it * 3547: Empty query when selecting a field from a view made of UNION ALL * 3551: Wrong ticks in TRACE * 3552: incorrect data results for "WHERE int_col <> 0" * 3554: Issue with subselect and ORDER BY * 3555: Order of evaluation inside CASE WHEN * 3558: numeric values (as strings) are incorrectly parsed/converted and invalid strings are accepted without error * 3560: Error "BATproject: does not match always" with subselect/groupby/having * 3562: mserver5: gdk_bat.c:2855: BATassertHeadProps: Assertion `!b->H->revsorted || cmp >= 0' failed. * 3563: incorrect results for scalar function locate(in_str, search_str, occurrence) * 3565: Wrong/confusing error message when trying to add a FK to a TEMP TABLE * 3572: Table names with escaped double quotes are rejected * 3573: alter table alter_not_null_test alter test set NOT NULL; is accepted when test contains null.

We would like to inform you that as of Januari 2013, the monetdb project on SourceForge will be removed. All services that SourceForge has kindly provided us with in the past will be migrated to our monetdb.org infrastructure. Currently, the only remaining services hosted on SourceForge are the three mailing lists monetdb-announce, monetdb-users and monetdb-developers. As of this message, these lists are migrated to their equivalents on monetdb.org. The new lists are as follows: monetdb-announce(a)lists.sourceforge.net -> announce-list(a)monetdb.org monetdb-users(a)lists.sourceforge.net -> users-list(a)monetdb.org monetdb-developers(a)lists.sourceforge.net -> developers-list(a)monetdb.org We invite you to subscribe to the new lists on monetdb.org at your earliest convenience. Any posts to the old lists are rejected from now on. Posts to the new lists at monetdb.org are forwarded in batches to the old lists until the end of this year. The MonetDB team would like to take this opportunity to thank SourceForge for the services provided over the past years. We hope to welcome all current subscribers on our new lists at monetdb.org, see: http://mail.monetdb.org/mailman/listinfo The MonetDB team

[Monetdb-announce] Announcement: New Jul2012 Feature release of MonetDB suite
by Fabian Groffen 17 Jul '12

17 Jul '12

The MonetDB team at CWI/MonetDB BV is pleased to announce the Jul2012 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 2012 feature release Build Environment * Created seperate RPM and DEB packages for MonetDB/JAQL. * Removed --enable-bits option from configure. * Split the MonetDB-client-ruby RPM package into two and named them in accordance with the Fedora packaging guidelines as rubygem-<gem-name>. SQL * COPY INTO now accepts optional parenthesis for file argument. Binary COPY INTO now requires 'COPY BINARY INTO'. Client Package * ODBC: Fixed a bug where SQLNativeSql expected a statment handle instead of a connection handle. MonetDB5 Server * Crackers code has been removed. Development continues in the holindex branch. Merovingian * Fixed misc memory leaks, which caused monetdbd to grow in memory size over time. * Removed erroneously (re-)added master and slave properties, this functionality is currently not working. MonetDB Common * Fixed intermittent problem that joins and selects return incorrect results and possibly inconsistent databases. The problems only occurred after a series of queries and updates, therefore it was hard to reproduce. * The sorted property, which was used to maintain whether a column in a BAT was sorted or reverse sorted, has been replaced by a pair of properties, sorted and revsorted. These new properties can be set independently (unlike the old sorted property), and so if both are set, the column must be constant. In addition, internal property checking has been overhauled. Now, when a property is set incorrectly, and when assertions are enabled, an assertion will go off. There is also a function which can derive properties. * Implemented proper overflow checking on all arithmetic operations. Bug Fixes * 3016: Overflowing double multiplication leads to incorrect result * 3091: Since Apr2012-SP1 !TypeException:user.s11_1[59]:'bat.reverse' undefined in: _89:any := bat.reverse(_86:wrd) * 3099: ambiguous attributes in query with WITH clause and EXISTS clause * 3100: charset problem with the odbc driver for windows * 3103: display_size and internal_size of Cursor.description or incorrect * 3105: Leaking using Python * 3109: Wrong order in autoload mal script causes warning on startup * 3111: memory leak, monetdb set/get command * 3112: Median over temporal domains * 3113: Cannot set value of indexed column when doing UPDATE * 3114: Foreign Key prblems * 3116: Segfault in SQL
