Version 1.180 - 2003-06-19 (GV)
-------------
+ A few more include of cassert in the test harnesses.

Version 1.179 - 2003-06-16 (GV)
-------------
+ Misc. fixes to make gcc-3.3 happy: include and/or

Version 1.177 - 2003-05-06 (GV)
-------------
+ Re-upload of 1.176 to fix permissions problem.

Version 1.176 - 2003-04-21 (GV)
-------------
+ (dal_description.tex) fix inclusion of error/warning
documentation.

Version 1.175 - 2003-03-06 (GV)
-------------
+ (SmartDalImplementation.cc) add a C-style int cast to make
gcc-2.95.3 happy. This should not be needed.

Version 1.174 - 2003-03-03 (GV)
-------------
+ (SmartDal) tweak interface to open sets. Add utility functions
to read/write string rows.

Version 1.173 - 2003-02-26 (GV)
-------------
+ (SmartDal) removed unused variables that triggered a warning ->
error.


Version 1.172 - 2003-02-25 (GV)
-------------
+ (compoundnames.cc) adjust the position of the attributes,
because now there is an extra attribute (LONGSTR).
+ (SmartDal) fix specialization of operator() so that gcc-2.95.x

Version 1.171 - 2003-01-29 (UL)
-------------
+ closed SPR 2405: printing pointer value

Version 1.170 - 2003-01-29 (GV)
-------------
+ (DalAttribute.cc) remove debug statement.
+ DEPEND: it needs error 1.41 or later.

Version 1.169 - 2003-01-28 (GV)
-------------
+ (Dal.h) Add some doxygen documentation.
+ Documentation updated for new list of errors and warnings.

Version 1.168 - 2003-01-27 (GV)
-------------
+ (FitsReaderWriter.cc) message for warning duplicateTableName now
spells out the table names explicitly. SOC-SPR-2362.
+ (FitsReaderWriter.cc) Give some more information when a FITS
data type that cannot be converted to one of the types supported
by the DAL is encountered. Test harness added. SOC-SPR-2360.
+ (DalDataSertServer.cc) add LONGSTRN attribute if not present, so
that fverify does not complain. This also required changing the
list of reserved keywords in dal_utilities.cc. SOC-SPR-2217.
+ (DalAttribute.cc) When an attempt is made to set an attribute to
NaN, catch the condition, issue a warning, clear the attribute
value and keep going. SOC-SPR-2294.


Version 1.167 - 2003-01-24 (GV)
-------------
+ Reference documentation lists all of the internal errors and
warnings.

Version 1.166 - 2003-01-21 (GV)
-------------
+ (MemFitsReaderWriter.cc) make message on number of rows appear
only when the verbosity is high. SOC-SPR-2397.
+ (SmartDal) memory model available on the open.
+ (daltypes.f90) make the data member of the custom types private,
so they cannot be tampered with from f90. This is a f95 feature.


Version 1.165 - 2002-01-07 (GV)
-------------
+ (SmartDal) Added smart pointer implementation of Dal.h, without
need to use the dataSetServer or delete methods.
+ (test/smart) Tests for the above.

Version 1.164 - 2002-01-03 (GV)
-------------
+ (HiLowFitsDatabase.cc:addEntry) use fits_create_tbl instead of
fits_insert_btlb when adding a new table. The latter requires a
priori knowledge of the size of the heap (PCOUNT) when the table
contains a variable length column. (SOC-SPR-2390)
+ (spr2338.cc) create the test dataset with cfitsio.

Version 1.163 - 2002-01-02 (GV)
-------------
+ (tests/sprtests/spr2390*cc) Show that the problem reported in
SOC-SPR-2390 is in the DAL and not in cfitsio.

Version 1.162 - 2002-12-13 (GV)
-------------
+ (Dal.h) Add declaration for osstream, and qualify std::ostream.

Version 1.161 - 2002-11-28 (GV)
-------------
+ Disable one test harness in test/misc as it was not ready
(required header files not yet part of DAL).

Version 1.160 - 2002-11-26 (GV)
-------------
+ (MemFitsReaderWriter.cc) re-implement the algorithm to
read/write tables to take advantage of cfitsio's buffering
capabilities. This makes the I/O about 3 times faster.

Version 1.159 - 2002-11-04 (GV)
-------------
+ (FitsReaderWriter.cc:readTableInfo) make the buffer holding a
long string keyword value larger to avoid segfault as in
SOC-SPR-2358.


Version 1.158 - 2002-09-09 (GV)
-------------
+ (FitsReaderWriter.cc) Get rid of an assert that cause the seg
fault described in SOC-SPR-1883.
+ (FitsReaderWriter.cc) Ignore reserved keywords out of context
instead of terminating with an error. (SOC-SPR-2141, SOC-SPR-2338)
+ (DalTable.cc) It is now impossible to add a table with name
PRIMARY, as this name is reserved for the primary image
(SOC-SPR-2311).

Version 1.157 - 2002-09-06 (GV)
-------------
+ The copyRows() implementation for variable length vector columns
was not always doing the right thing. It now works
(SOC-SPR-2343). Also, when asked to make a copy so that from ==
to, do nothing instead of uselessly copying. Test harness spr2343
added.

Version 1.156 - 2002-09-01 (GV)
-------------
+ Reorganize directories, remove dead code, make tests run one at
a time. No functional changes.

Version 1.155 - 2002-06-27 (JBa)
------------
+ Preparation for GCC 3.1
+ Added virtual to otherwise dangerous destructors

Version 1.154.3 - 2002-04-12 (GV)
---------------
+ (dal_implementation.cc::settonullcolumn) When accessing an
element it should allow for the possibility of a seek having being
done on the table. Change row into row +
col->from(). SOC-SPR-2289. Corresponding test harness added under
sprtests.

Version 1.154.2 - 2002-01-25 (GV)
---------------
+ Misc. doc fixes (SOC-SPR-2224)
+ Enable unsigned variable length vector column test in spr2159.cc


Version 1.154 - 2002-01-24 (GV)
-------------
+ (sprtests) activate test harnesses related to SOC-SPR-2159: spr2159,
spr2159f90, and vlcaddcolumns (this one related to SOC-SPR-2251).

Version 1.153 - 2002-01-21 (GV)
-------------
+ (DalDataSetServer.cc) update history records in the open instead
of the close. This solves SOC-SPR-2253 (History records
duplicated). Test harness: spr2253.

Version 1.152 - 2002-01-17 (GV)
-------------
+ (DalTable.cc) remove extra check on number of elements of a
vector column, as it is ok to have an n dimensional vector columns
with 0 extent (SOC-SPR-2254).

Version 1.151 - 2002-01-14 (GV)
-------------
+ (FitsReaderWriter.cc) It was incorrectly adding an empty
XPROC. The new cfitsio now writes out empty string keywords, and
this was causing the test harness process.cc to fail.
+ Activate a number of test harnesses that had highlighted cfitsio
problems. Most of them now pass.

Version 1.150 - 2001-11-01 (GV)
-------------
+ move templates back into Dal.h
+ DataSetServer::open: using an empty set name generates a
comprehensible error message.

Version 1.149 - 2001-10-30 (GV)
-------------
+ template specialization (see 1.148) works also for bool8.
+ move actual specializations away from Dal.h in DalDal.cc.

Version 1.148 - 2001-10-25 (GV)
-------------
+ Dal.h: add template T * Data::data() const; and
corresponding specializations.

Version 1.147 - 2001-10-22 (GV)
-------------
+ dal.f90: add i/f to dataSetServer::client
+ add std namespace qualifiers
+ dal_implementation.cc: change the behavior of stringcell, so
that f9x's trim function works as expected.
+ sprtests: add test harness for the above.

Version 1.146 - 2001-10-18 (GV)
-------------
+ (sprtest/Makefile) add more tests for SPRs.

Version 1.145 - 2001-10-16 (GV)
-------------
+ (HiLowColumn::insertRows()) now works in low mem (solves 1/3 of
SOC-SPR-2192).
+ (HiLowColumn::deleteRows()) now works in low mem (solves another
1/3 of the same SPR).
+ (HiLowColumn::copyRows)) as above, final 1/3 of SPR.

Version 1.144 - 2001-10-11 (GV)
-------------
+ (DalDataSet::blockNumber()) clarify error message for some cases
of wrong compound syntax. SOC-SPR-2097 and SOC-SPR-2104.

Version 1.143 - 2001-10-11 (GV)
-------------
+ (DalTable::deleteColumn()) release the data before deleting the
column. SOC-SPR-1962.
+ (DalDataSet::releaseBolck()) idem.
+ (DalTable::deleteColumn()) make sure column access mode is reset
when column is relased. SOC-SPR-2124.

Version 1.142 - 2001-10-05 (GV)
-------------
+ (dal.f90) add numberOfelementsOfCell(column, row) to be used
with variable length vector columns.
+ (dal_implementation.cc) implementation of the above,
(setvariablecolumn.f90) test harness adapted to new interface.

Version 1.141 - 2001-10-04 (GV)
-------------
+ (MemColumn::insertRows()) now does variable length columns
correctly (SOC-SPR-2167: himem only).
+ Implement MemColumn::deleteRows() and MemColumn::copyRows() also
for variable length vector columns.

Version 1.140 - 2001-10-02 (GV)
-------------
+ (spr2159.cc) comment out some of the code, as it rquires a cfitsio
version that is not yet available.
+ Now it stops cleanly when trying to insertRows on a variable
length vector column. t still does not work though.

Version 1.139 - 2001-10-02 (GV)
-------------
+ Typo in DalTable.cc

Version 1.138 - 2001-10-01 (GV)
-------------
+ implement set->add(block) so that it also works with tables that
contain variable length columns. SOC-SPR-2159.
This boils down to implementing MemColumn::assignVariable and
HiLowColumn::assignVariable. Add test harness.


Version 1.137 - 2001-07-25 (UL)
-------------
+ fixed minor compilation problem under -O in dalcom/dal_utilities.h
(for details see SPR 2131: Fails to compile)

Version 1.136 2001-05-31 (MT)
------------------------
- Fixed a suble problem with Table::seek(); it should now work
correctly with the high memory model.
- Overhauled the implementation of the dataset server.
- cxx: Implemented the following method

// *******************************************************************
// The client name to which which a dataset is to be associated
// is set using the method DataSetServer::client( const string&
// clientName ). Whenever a dataset is opened it is always associated
// with the current clientName.
// The cleanupClient( const string& clientName ) method iterates
// through all open datasets and closes those (regardless of the
// reference count) datasets whose client name
// matches the given client name.
// *******************************************************************
/** Flush all the datasets associated with the named client back to
disk.
* @param clienName The name of the client. */
virtual void DataSetServer::cleanupClient( const string& clientName ) = 0;

---------------> THIS METHOD MUST ONLY BE CALLED BY METAtASKS.

- f90: Implemented the following subroutine (it has the same functionality as
described above)

subroutine cleanupClient( clientName )
character(len=*), intent(in) :: clientName

call error( "", errorMessage )

end subroutine cleanupClient

---------------> THIS SUBROUTINE MUST ONLY BE CALLED BY METAtASKS.

Version 1.135 2001-05-22 (MT)
------------------------
- Updated the FITS readerWriter to work with the latest cfitsio; i.e. the
proceesing of COMMENT and HISTORY no longer removes the two spaces
which older versions of cfitsio prepended to COMMENT and HISTORY
records.

Version 1.134.5 2001-05-23 (MT)
---------------
- dalcomtests now run correctly; also rolled back version 1.135 (temporarily).

Version 1.134.4 2001-05-22 (MT)
---------------
- Test harnesses now work in low memory mode again.

const char* units );

Attribute * addRealAttribute(
Attributable* attributable,
const char* name,
double value,
const char* comment,
const char* units );

Attribute * addStringAttribute(
Attributable* attributable,
const char* name,
const char* value,
const char* comment );

Attribute * addBoolAttribute(
Attributable* attributable,
const char* name,
bool value,
const char* comment );


Version 1.134.1 2001-05-07 (MT)
---------------
- The dal test harness is no longer run in low memory mode; this is
now being done automatically by the system build procedure.

Version 1.134 2001-04-23 (MT)
-------------
- Implemented a method
ColumnData * Column::rowData(
unsigned long rowNumber,
AccessMode accessMode=AsParent )
which can be used to access either Fixed or Variable length column data.
+ Implemented cxx test harness cxxtest/fixvarcolumn.cc which shows how an
example of how to use it.
- Table::seek() now works correctly in high memory mode.
- Optimsed the way in which the DAL checks the format of FITS files.

example of how to use it.
+ Implemented the f90 type:
type TableSeekerT
integer, pointer :: ptr
end type
+ Implemented the following f90 dal modules/functions/subroutines:

! Functions/Subroutines related to the TableSeeker class
function newTableSeeker( table )
type(TableT), intent(in) :: table

type(TableSeekerT) :: newTableSeeker

call error( "", errorMessage )

end function newTableSeeker

subroutine releaseTableSeeker( tableSeeker ) ! accessible through release interface
type(TableSeekerT), intent(in) :: tableSeeker

call error( "", errorMessage )

end subroutine releaseTableSeeker

function tableSeekerNext( tableSeeker ) ! accessible through interface next
type(TableSeekerT), intent(in) :: tableSeeker

call error( "", errorMessage )

end subroutine resetTableSeeker

+ Implemented fortran90 test harness f90test/tableseeker.f90, which shows an
example of how to use it.

-------------
- The DAL now strips one of single quotes from each 'pair of single quotes'
from string attribute values.

-------------
+ remove obsolete c++ headers.

Version 1.131 2001-03-12 (MT)
-------------
- Inhibit the message about file fomats being unrecognised.
- Change the way in which the DataSetServer::exists() method works; it now
uses the fits::open() & fits::close() sequence to determine if the
given dataset is in fits format(). This should allow support for
a fits file in gzipped format.

Version 1.130.3 2000-12-20 (MT)

The High Memory Fits Writer now correctly deletes the ColumnData objects
which it uses to access the data to be written to disk.

Version 1.127 2000-09-26 (MT)
-------------
- The fully qualified name of unreleased data objects is now displayed
by the DAL. The message has also been upgraded to a warning.

Also improved the error and warning messages produced by the setData()
funtion.
- Closed SPR-1742 : verbosity of messages
Dal messages are now done with Msg::Core. Dataset access messages are
now Msg::Sparse. Other object access messages are now Msg::Noisy.

-------------
- Fix cxxtest/insertrow.cc test harness.

Version 1.121.2 2000-06-22 (MT)
-------------
- Re-organise the way in which table/columns are read, so that
dspurify/MemFITSReaderWriterX.cc can
easily ignore invalid columns, but read valid columns.
- When opening a dataset the DAL now outputs a debug message indicating
the number of datasets currently in memory.
- When opening/closing a file the DAL now outputs a debug message if the
operation gives rise to a change in the number of fits files currently open.
- Improved log messages when opening/closing datasets.

string passing between 90 and c++ more reliable.

Version 1.121 2000-05-22 (MT)
-------------
- When a reserved keyword is found in a table extension, but has no purpose
e.g. DATE or CREATOR, a more descriptive error message is raised.

-------------
- Row-wise column writing is now the default. The enviroment
variable SAS_ROW_WISE has been renamed to SAS_COLUMN_WISE.
SAS_COLUMN_WISE should be defined in order to activate
column-wise writing.

Version 1.119 2000-05-17 (MT)
-------------
- ExtDal: forEachSubTable no longer keeps its own list of columnData
objects, but lets the column's data clerk take care of this house-keeping.
Modified test harnesses appropriately.
- f90: f90test/forEachSubTable.f90 test harness now releases columns (this
is now necessary because forEachSubTable no longer does this).
- f90: after forEachSubTable has completed, the table's subrange (seek)
is reset to its default.
- f90: implemented seek( from, count ), which has been overloaded from both
columns and tables.
- XPROC records are no longer being duplicated in lowmem mode.
- Insert/Delete Rows in himem mode is now more reliable.
- Allow Creator/Date to set for individual datasets.
CREATE & DATE are now reserved keywords
The DataSetServer class has been extended with the following methods:

...
/** Get/Set Creator and DatФ
*/
virtual void creator(
const DataSet* dataSet,
const string& creator ) = 0;

virtual const string& creator( const DataSet* dataSet ) const = 0;

virtual void date(
const DataSet* dataSet,
const string date ) = 0;

XPROCnnn is now a class reserved keywords.
The DataSetServer class has been extended with the following methods:
class DataSetServer {
...

/** Register a description of the process that is going on.
When a dataset is closed processDescription is added to the
process history list.
*/
virtual void process( const string& processDescription ) = 0;
virtual const string& process() const = 0;

/** This adds processDescription to the given dataset's
process history list.
*/
virtual void process(
const DataSet* dataSet,
const string& processDescription ) = 0;

virtual const string& process(
const DataSet* dataSet,
unsigned int processNumber ) const = 0;

virtual unsigned int processes( const DataSet* dataSet ) const = 0;
...
};

manner.
- cxxtest/columnrow.cc test harness implemented
- f90test/columnrow.f90 test harness implemented
- A message is now issued if a dataset is closed before releasing
all data.
- f90: Accessing columns by row is now more reliable.

Version 1.110 2000-03-17 (MT)
-------------
- The DAL is now able to read a FITS table which has
a very large number of columns, quickly and efficiently.
The environment variable SAS_NO_COLUMN_ATTRIBUTES now
has no effect.
- Error message about attribute not found is now in correct format.

Version 1.109 2000-03-14 (MT)
-------------
- Extended cxx deleteattribute.cc test harness to test with all object
attributes.
- Deletion of attributes now works in Low mem mode.
- XMMSEP is now a reserved attribute name.
- In low mem mode, the history, comments and attributes are now
not modified (in fact, deleted) until the dataset is closed.
- Additional test harness cxx/varlengthcolumn.cc
- Implement a switch which skips the reading of the column attributes from a fits
file; this:
+ IS A TEMPORARY FIX TO IMPROVE THE PERFORMANCE OF THE DAL WHEN READING
A FITS FILE WHICH CONTAINS A LARGE NUMBER OF COLUMNS. IT
WILL BE REPLACED LATER BY A MORE EFFICIENT ALGORITHM.

Version 1.53 (MT)
-----------------
- Use of macros and templates in dal_implementation.cc to reduce code size.
- Closed SPR-611 : copyBlock does not work on vector columns
* a known feature (not necessarily a bug) of copyBlock is that any
exisiting data pointers (e.g. coldata = int32ColumnData( col ), where
col is contained in either the destination set or the source table )
relating to either the source or destination
objects will become stale; the test harness f90test/copyblock.f90
illustrates this behaviour.
* New test harness (f90test/copyblock.f90) for copyblock.
* copyBlock now works on arrays
* a known bug still exisitng with copyBlock is that it does not yet
work on variable length columns.
- Closed SPR-612 : intnnAttribute is wrong for AttributableT arguments

* All the f90 derived types (from daltypes.f90) are now public
in dal.f90 (including AttributableT).
