05 December 2018 - Version 0.18.1

Bug

• [ODB-392] - test_encode_odb fails with Cray compiler 8.6

Improvement

• [ODB-434] - Fix DynamicParametisation following eckit API change

June 2018 - Version 0.18.0

This version introduces changes required for compatibility with a C++11-only software stack.

Bug

• [ODB-422] - Error message on duplicate column is nonsensical

Improvement

• [ODB-362] - Use new lest-compatible unit testing from eckit for ODB tests.

• [ODB-421] - C++11 as minimum requirement

October 2017 - Version 0.17.6

Bug

• [ODB-390] - Fix FileMapper TIME for odbServer (correct broken test)

Improvement

• [ODB-393] - Analysis of ODB meta data coming from marsfs should buffer data

October 2017 - Version 0.17.4

Bug

• [ODB-388] - odb mdset sometime produces incomplete files
• [ODB-391] - test_decode_odb has macro with wrong number of arguments

Improvement

• [ODB-387] - odb compare should accept a list of columns not to test
• [ODB-390] - Fix FileMapper TIME for odbServer

Specific note

ODB-390 (changes to FileMapper) changes the default handling of TIME in the archiving operations. This has been done to align the versions of ODB API used in operations at ECMWF with those that are externally released. If the older behaviour is desired, this can be restored by setting the environment variable:

ODB_PATCH_TIME_ENCODE_RELATIVE=true

September 2017 - Version 0.17.3

Bug

• [ODB-356] - Tests fail when dependency order is not obeyed
• [ODB-379] - ODB-2 distance function out by a factor of 10
• [ODB-376] - Garbled data can be returned from odb::Reader from malformed ODB file (rather than error)

Improvement

• [ODB-159] - ODB API 1.0: Use codec which fixes ODB-15 for encoding by default
• [ODB-362] - Use new lest-compatible unit testing from eckit for ODB tests.

July 2017 - Version 0.17.2 (Internal only)

Bug

• [ODB-365] - Build failure on FreeBSD
• [ODB-367] - The "chars" codec stores all of its data twice
• [ODB-369] - Values can be promoted into missingValue silently, without being registered in statistics
• [ODB-372] - Writer will happily create output with columns with repeated names
• [ODB-374] - Failure during writing header of string-based types in odb mdset
• [ODB-375] - Internal segfault if columns are not correctly initialised

Improvement

• [ODB-362] - Use new lest-compatible unit testing from eckit for some of the ODB tests.
• [ODB-363] - Added tests for data encoding/decoding and codecs.

June 2017 - Version 0.17.1

Primary change is the removal of ODB1 dependencies from ODB API (and extraction of those components into odb_tools).

Bug

• [ODB-351] - Legacy Fortran API syntax error if SQL not terminated with semicolon
• [ODB-353] - Default paths in oda2request are incorrect, causing failures
• [ODB-354] - Cmake is checking for FortranLibs when just checking if the Fortran compiler works should be sufficient

23 May 2017 - Version 0.17.0

Bug

• [ODB-52] - Crash when trying to open files that don't exist
• [ODB-246] - Problem compiling odbql_wrappers.f90
• [ODB-324] - ODBServer project should be declared as Fortran?
• [ODB-331] - Python interface: files not closed after executing SELECT.
• [ODB-334] - Inconsistent NetCDF variable naming
• [ODB-342] - Data Governance tools - Creation of new groups through update_odb_obsgroups.sh is broken
• [ODB-347] - odb sql command line fails with syntax error if terminating semicolon is missing
• [ODB-349] - A race condition in ODB API SQL (Bitfields' types registration)

New Feature

• [ODB-83] - ODB API Python interface to accept multiple files as SQL input

Improvements

• [ODB-127] - $ variables in ODB2
• [ODB-317] - Make OpenMP optional
• [ODB-319] - Allow ODB-API to be built without OpenMP support

March 2017 - Version 0.16.2

Fixes

• [ODB-169] - Add an alias 'mean' to 'avg' for ODB-1 compatibility
• [ODB-313] - odb_migrator was crashing in verification stage for some ODB databases

New Features

• [ODB-300] - 'odb count' can accept more then one file name as parameter and return total sum of row counts.
• [ODB-303] - Incorporate MetOffice patch for ODB Server so time is formatted as 4 digits (optional compile-time feature)
• [ODB-306] - Make the verification of split optional (option -no_verification)
• [ODB-312] - Make verification optional in odb_migrator (option -no_verification)

0.16.1

• [ODB-166] - Portability issues affecting clang compilers builds, including Mac OS
• [ODB-286] - Improve SQL syntax error messages
• [ODB-284] - Less verbose logging for functionality called by MARS client and server

0.16.0

• [ODB-269] - Python API: files were not closed properly. Python programs opening many files could reach operating systems limit on number of open files.
• [ODB-281] - New SQL functions: (aggregate) first and last.
• [ODB-271] - Python API: Pass file name to function connect instead of DDL, see updated examples.

...

• Updated to use eckit 0.6.0 and ecbuild 1.3.2
• Table in the SELECT's INTO clause can be defined with a CREATE TABLE statement (ODB-67)

• odb sql tool has new flags (ODB-85):

  [--binary]            Print bitfields in binary notation

  [--no_alignment]      Do not align columns

• Python API for legacy ODB added (documentation to be written)
• ...

...

• "ORDER BY 1" was not working correctly (ODB-49)
• oda2request tool broken in ODB API 0.9.31 (wrong default path to configuration) (ODB-70)
• CSV import tool was not working correctly for some bitfield columns (ODB-76)
• ODB_DOUBLE constant added to Fortran bindings (ODB-77)
• Python API for accessing old ODB databases (ODB-74)
• Added odb_migrator option to specify missing value indicators different than default ones (only for REAL and INTEGER currently, DOUBLE always the same as REAL, BITFIELD always 0) (ODB-68)

            Syntax: 
               -mdi <type1:MDI1,type2:MDI2,...>
            e.g.:
              -mdi REAL:2147483647,INTEGER:2147483647
