ChangeLog

2013-02-07 Version 3.12.0 Vincent Rogier vince.rogier@ocilib.net

    * Added support for lob prefetching introduced in 11gR1
    
       - Added OCI_GetDefaultLobPrefetchSize()
       - Added OCI_SetDefaultLobPrefetchSize()
       
    * Enhanced Direct Path API  
    
       - Added OCI_DirPathSetConvertMode() that gives the ability to force direct path conversions
       - Modified OCI_DirPathGetErrorRow() and OCI_DirPathGetErrorColumn() behavior that can return all erred rows/columns after a conversion or load operation
       - Added direct path demo file dirpath_complete.c
       - Updated documentation
       
     * Fixed Direct Path API  
      
       - Fixed direct path logic when stream buffer are too small (OCI_DirPathConvert() returning OCI_DRP_FULL)
       - Fixed direct path logic when conversion and loading errors occur
       - Fixed OCI_DirPathConvert() that support now resuming conversion when an error occurs by fixing values and calling OCI_DirPathConvert() again in default mode (in previous releases duplicated rows were inserted in database)
       - Fixed OCI_DirPathGetErrorRow() and OCI_DirPathGetErrorColumn() that returned zero based row/column indexes instead of being 1 based row/column indexes 
       - Fixed OCI_DirPathSetEntry() : Setting NULL values on column that had decimal/date format throwed an Oracle error
    
    * Fixed Oracle Streams AQ (Advanced Queues) asynchrounous notifications :
    
       - Fixed possible race condition in OCI_DequeueSubscribe() that could cause to have the internal callback called before the user callback was assigned to the dequeue object
       
    * Fixed numeric/ string conversions :

       - Fixed OCI_GetInt(), OCI_GetShort(), OCI_GetBigInt() and unsigned versions when the column type was string based (bug in string/number conversion introduced in v3.11.0)

    * Miscellaneous fixes :   

       - Fixed wrong column buffer size computation for strings, rowids and longs when using OCI_CHARSET_WIDE or OCI_CHARSET_MIXED on unixes platforms

2012-12-19 Version 3.11.1 Vincent Rogier vince.rogier@ocilib.net

    * Fixed broken support for Oracle Database Change notifications
    
       - Fixed OCI_SubscriptionRegister() : Previous version 3.11.0 introduced a bug in subscription registration  

    * OCILIB Thanks file was missing in 3.11.0 packages. It is reintroduced within this release.     

2012-12-12 Version 3.11.0 Vincent Rogier vince.rogier@ocilib.net

    * Extended Oracle Streams AQ (Advanced Queues) support :
    
       - Added support for asynchrounous notifications (Petr Vanek proposal) :       
          - Added OCI_DequeueSubscribe()
          - Added OCI_DequeueUnsubscribe()
          - Added demo file queue_async.c
          
    * Fixed And Enhhanced support of BINARY FLOAT and BINARY DOUBLE types :     
      - Updated OCI_GetDouble(), OCI_GetDouble2(), OCI_GetFloat(), OCI_GetFloat2() : 
          - In previous releases, BINARY FLOAT and BINARY DOUBLE were fetched as NUMBER and locally converted to native double and float types using Oracle Client API
          - With this release, BINARY FLOAT and BINARY DOUBLE are directly fetched as native double and float types
      - BINARY FLOAT and BINARY DOUBLE were not supported in Oracle Objects and Oracle Collections (TYPES, VARRAYs and NESTED TABLES)
          - In previous releases, segfaults could happen when manipulating objects with BINARY FLOAT and BINARY DOUBLE members or collections of BINARY FLOAT and BINARY DOUBLE
          - With this release, BINARY FLOAT and BINARY DOUBLE are fully supported within OCI_Elem and OCI_Object
      - Updated OCI_BindDouble(), OCI_BindArrayOfDoubles(), OCI_BindFloat(), OCI_BindArrayOfFloats() 
          - If the Oracle client supports BINARY FLOAT and BINARY DOUBLE types (Oracle 10g and above), host double and float variables are binding as BINARY FLOAT and BINARY DOUBLE instead of NUMBER.
          - This prevent the Oracle client from performing internal conversions. 
      - Enhanced String conversions :
          - When OCILIB has to convert BINARY DOUBLE values to/from strings, it now supports the double type full range of values.
          - OCILIB uses now the C runtime to perform BINARY DOUBLE and BINARY FLOAT conversions to/from strings as the Oracle Client API cannot handle the full double datatype wihtin its string conversion API
 
    * Miscellaneous changes :
    
      - OCI_GetString() : Conversion from numeric types has been rewritten, much cleaner code now
      - Internal numeric types handling (conversions between numeric types, to/from strings) has been rewritten
      - Miscellaneous code updates : OCILIB source code has been tested against various code analysis tools
      - Documentation updates
      - Added pkgconfig support for Unixes/Linux platforms (thanks to Petr Vanek)
          
    * Miscellaneous fixes :
    
      - OCI_GetBatchErrorCount() always returned 0
      - OCI_FileGetDirectory() did not set error flag for OCI_GetLastError()
      - OCI_ElemGetRaw() was setting error flag to TRUE in all cases for OCI_GetLastError()
      - OCI_PoolGetStatementCacheSize() was setting error flag to FALSE in all cases for OCI_GetLastError()
      - OCI_LobRead() and OCI_LobRead2() : In OCI_CHARSET_WIDE and OCI_CHARSET_MIXED builds, values could be truncated with Oracle clients 8i and 9i only
      - OCI_LobWrite2() and OCI_LobAppend2() : returned byte count may not been accurate for CLOB when using OCI_CHARSET_WIDE or OCI_CHARSET_MIXED builds
      - OCI_ColumnGetCharUsed() : Attribute introduced in Oracle 9.2 but OCILIB tried to retrieve it from Oracle 9.0 as well
      - OCI_ConnectionFree() could generate a segfault on a reused connection retrieved from a connection pool since version 3.10.0
      - OCI_TypeInfoGet() could generate a segfault in OCI_CHARSET_WIDE builds when a table/view column or object member was an Oracle Type (Object and Collection)
      - OCI_xxxFmt() calls : Timestamp arguments were not formatted correctly (missing quotes in the formatted SQL)     
      - Scrollable Statements : 
          - An Oracle error (ORA-01001 or ORA-01002) was thrown when fetching a statement (PL/SQL Cursor or Nested table) that was returned by a select statement that contained more thant one column
          - This happened only if the statement was retrieved from a scrollable statement using array fetching (internal OCILIB default behavior)
          - This is an Oracle bug and a workaround has been found
          - Now, OCILIB internally sets the resultset internal array size to 1 and thus ignore any values set using OCI_SetFetchSize() for such statements

    * Modified Prebuilt MS Windows binaries
    
      - Official Windows OCILIB Binaries are now built using MS C compiler optimization capabilities (compiler remains MS Visual Studio 2010 Express) :
          - Full optimization compiler flag (/Ox)
          - Whole program optimization flag (/GL)
        
2012-08-08 Version 3.10.0 Vincent Rogier vince.rogier@ocilib.net

    * Added support for native C float datatype :

      - Added OCI_GetFloat()
      - Added OCI_GetFloat2()
      - Added OCI_BindFloat()
      - Added OCI_BindArrayOfFloats()
      - Added OCI_RegisterFloat()
      - Added OCI_ElemGetFloat()
      - Added OCI_ElemSetFloat()
      - Added OCI_ObjectGetFloat()
      - Added OCI_ObjectSetFloat()
      - Added constant OCI_ARG_FLOAT
      - Added constant OCI_NUM_FLOAT
      - Use the input identifier '%g' for OCI_StmtxxxxFmt() calls when passing float variables
      - Updated demo application to use float datatype 
      
    * Fixed OCI_IntervalArrayCreate() : wrong internal handle type caused the function to fail to allocate the array with the right interval type
      
2012-06-29 Version 3.9.4 Vincent Rogier vince.rogier@ocilib.net

    * Miscellaneous fixes

      - Connection and Session Pools : Fixed few bugs related to OCILIB automatic adaptation to runtime client versions and features that could lead OCI_PoolGetConnection() to return NULL
      - Statement cache was not properly activated when feature was available
      - OCI_PoolGetStatementCacheSize() : an error was raised as an invalid internal oci attibute code was used
      - Fixed broken compilation support for Oracle 8i and 9i clients on unix platforms when oracle shared lib import mode is OCI_IMPORT_LINKAGE
      - Oracle 11g : OCILIB driver name could not be properly set in the view V$SESSION_CONNECT_INFO
      - Oracle XA :
          - Unix platforms : No change, XA is supported for all Oracle Clients >= 8i
          - MS Windows Platforms :
              * When using the Dlls provided in OCILIB releases, XA wis now enabled only if the Oracle client loaded at runtime has XA symbols embedded in oci.dll (usually >= Oracle 10g)
              * When compiling yourself OCILIB, support is enabled only with Oracle Client 10g and above as on MS Windows, for 8i and 9i, specific import libraries are used and can be missing in some installations             
              * So when XA is not enabled, using the flag OCI_SESSION_XA with OCI_ConnectionCreate() will now throw an exception
     
    * Miscellaneous changes
    
      - default transaction behavior :
      
          - Prior to v3.9.4, a default transaction object was created in OCI_ConnectionCreate() and associated to the returned connection object. 
          - From v3.9.4
              * No changes for regular standalone transactions and transactions retrieved from connection pool.
              * For XA connections and connections retrieved from session pool, no transaction object is created anymore and thus, OCI_GetTransaction() will return NULL for newly created connections.
              * Note that transaction objects must not be set to connections retrieved from a session pool or to XA connections
              * For other types of connections (regular or retrieved from connection pool), transaction objects can be used as normal
      
      - Various internal minor code change
      - Note that all sources files have been updated to include year 2012 in the copyright section 
       
2011-12-05 Version 3.9.3 Vincent Rogier vince.rogier@ocilib.net

    * Miscellaneous fixes

      - Fixed broken support for Oracle 8i client since v3.9.0
      - Fixed OCI_ObjectSetObject() : a bug had been introduced in v3.8.1 when computing internal object structure offsets and paddings 
      - Fixed OCI_LobRead(), OCI_LobRead2() : in OCI_CHARSET_WIDE charset builds only, a segfault could happen caused by an internal buffer overwrite    
      - Fixed OCI_SetStatementCacheSize(), OCI_GetStatementCacheSize() : an error ORA-24315 (with no incidence) could be thrown by some versions of Oracle clients
      - Fixed OCI_BindXXX() : All binding methods returned TRUE instead of FALSE when an exception OCI_ERR_MAX_BIND occured
      - Fixed OCI_GetString() : an error OCI-22061 was happening when the column was numeric and a user defined numeric format where provided with OCI_SetDefaultFormatNumeric()
      - Fixed OCI_GetServerRevisionVersion() : it was returned the same value as OCI_GetServerMajorVersion() since v3.4.0
      - Fixed internal method OCI_ParseSqlFmt() used in OCI_xxxFmt() calls : Quoted strings were not properly output since v3.9.0
      - Fixed internal allocation mode : 

          - some OCI_BindXXX() calls were not compatible with OCI_BAM_INTERNAL allocation mode and when used with it, were causing segfaults if the host variable parameter was NULL
          - now these methods raise an OCI_ERR_NULL_POINTER error if the host variable parameter is NULL and the statement bind allocation mode is set to OCI_BAM_INTERNAL

    * Miscellaneous changes

      - OCILIB library compilation

          - Modified compile time detection of OCI client version when using OCI_IMPORT_LINKAGE as Oracle backported some defines introduced at version (X) in patches for version (X-1) !

      - OCILIB documentation

         - Updated Bind allocation mode description : added list of incompatible OCI_BindXXX() methods
         - Added OCI_BAM_INTERNAL compatibility information in all OCI_BindXXX calls() documentation
         - Added OCI_ENV_EVENTS requirements for subscriptions and HA methods
         - Minor changes

     - few code internal minor changes

     - Removed in each OCILIB source file, the version number and date time (updated at each new release, using diff tools was a nigthmare !)

2011-07-13 Version 3.9.2 Vincent Rogier vince.rogier@ocilib.net

    * Miscellaneous fixes

      - Detection of the 'long long' type on unix/linux platforms is now working as expected in all situations
      - version 3.9.0 broke support of Oracle client versions < 10g when using OCI import mode OCI_IMPORT_LINKAGE (default option on unix/linux platforms)

2011-07-08 Version 3.9.1 Vincent Rogier vince.rogier@ocilib.net

    * Miscellaneous fixes

      - Fixed OCI_BindString() : version 3.9.0 introduced a memory leak when using this method
      - Fixed OCI_IsNull()     : version 3.7.0 introduced a bug when OCI_IsNull() was called for OCI_CDT_OBJECT columns. It always returned FALSE
      - Fixed OCI_GetStruct()  : version 3.7.0 introduced a bug (same as above) that caused the indicator array parameter filled with wrong indicator values for OCI_CDT_OBJECT columns
      - Fixed use of "Returning into" SQL clause : version 3.9.0 broke re-execution of a prepared statment that contains a "returning into" sql clause

2011-04-20 Version 3.9.0 Vincent Rogier vince.rogier@ocilib.net

    * Added support Oracle XA

      - Oracle XA integration in OCLIB is transparent by using OCI_ConnectionCreate() and requires just :
      
         - an XA db name for parameter 'db'
         - an extra flag OCI_SESSION_XA for parametrer 'mode'
         - no user or password
          
      - See the OCI_ConnectionCreate() documentation for the XA open string needed by OCILIB to pass to the TMP 

    * Added support for statement cache

      - Statement cache is now automatically enabled when using an Oracle client >= 9iR2
      - Added statement cache size customization when using an Oracle client >= 10gR1 :
        
        - Added OCI_SetStatementCacheSize()
        - Added OCI_GetStatementCacheSize()
        - Added OCI_PoolSetStatementCacheSize()
        - Added OCI_PoolGetStatementCacheSize()

    * Added support for TAF (Transparent Application Failover) and HA (High availabality) 
    
      - The following handler has been added when using an Oracle client >= 10gR2

        - Added OCI_IsTAFCapable()
        - Added OCI_SetTAFHandler()
        - Added OCI_SetHAHandler()

    * Added support for Connection attributes introduced in Oracle 10gR2 

      - Added OCI_GetDBName()
      - Added OCI_GetInstanceName()
      - Added OCI_GetServiceName()
      - Added OCI_GetServerName()
      - Added OCI_GetDomainName()
      - Added OCI_GetInstanceStartTime()

    * Improved bind tuning. Now it is possible to set the bind direction mode (in, out, in/out) for slightly better performance 
    
      - Added OCI_BindSetDirection()
      - Added OCI_BindGetDirection()

    * Miscellaneous new calls :

      -  Added OCI_Describe() and OCI_DescribeFmt() to enable the retrieving of an OCI_Resultset object for 'select' statement wihtout exectuing the SQL

    * Miscellaneous changes :

      - Reenforced checks on OCI_Statement handle related methods that checks the statement state (prepared, executed, parsed,...) that now can throw more exceptions
      - Updated layout of some internal structure to supress unnecessary padding
      - Manual update of source code formatted with Uncrustify (wrong indentation of preprocessor directives)
      - User callbacks were not correctly documented
      - Updated Doxygen version used to generate the documentation (update in the output html style)

    * Miscellaneous fixes :

      - Fixed Binding call using the binding mode OCI_BAM_INTERNAL :

        - arrays of Lobs, Files, Intervals and timestamps : internal objects were not properly initialized
        - big_int : single bind and array bind were incorrectly implemented (allocation size wrongly computed that lead to a segfault for arrays)   
        - strings : 
          
          - single binds : if the length parameter was set to 0, a segfault happened 
          - Wide strings : if the native Oracle Unicode used a different size than the C runtime for wchar_t (like unix like system) translation were not performed by OCILIB 

      - Fixed 11Gr2 compile time detection when using OCI_IMPORT_LINKAGE (default on Unix platform)   
      - Fixed OCI_ImmediateFmt() : the method returned FALSE even on success
      - Fixed OCI_PoolGetConnection() : OCILIB tried to set the driver name attribute (appeared in 10gR2) on the session that is not allowed anymore in 11g
      - Fixed OCI_SetFormatDate() macro : fixed macros parameters declaration
      - Fixed OCI_ColumnGetNullable() returned value
      - Fixed OCI_ConnectionCreate() : 2 OCI handles not freed if connection failed
      - Fixed OCI_SetPrefetchSize(), OCI_SetPrefetchMemory() : the given value was not really passed to Oracle
      - Fixed OCI_TypeInfoGet() called internally when fetching object owned by a different schema
      - Fixed OCI_Parse() : the method was internally doing a describe operation instead of just a parse (which gave same results from an end user view)
      - Fixed OCI_LobAssign() that was not handling correclty Lob arrays created with OCI_LobArrayCreate()
      - Fixed OCI_BindDouble() and OCI_BindArrayOfDoubles() : internal sub numeric type OCI_NUM_DOUBLE was not set on the bind handle
      - Fixed OCI_StringGetFromAttrHandle() allocation of insuffucient buffer in unicode mode
      - Fixed OCI_ObjectSetxxx() could return true if attribute not found
      - Fixed Queues function in OCI_CHARSET_MIXED mode

2010-12-13 Version 3.8.1 Vincent Rogier vince.rogier@ocilib.net

    * Miscellaneous fixes

      - Fixed internal computation of OCI_Object attributes null indicator offsets
      - Fixed OCI_Elem handle initialization by OCI_CollGetAt() and OCI_CollGetAt2()
      - Fixed OCI_Ping() : OCI symbol OCIPing() was not dynamically loaded if OCI_IMPORT_RUNTIME was used (default for precompiled MS Windows Dlls)
      - Fixed OCI_ConnectionCreate() : in case of an unsuccessfull attempt to create a connection, an OCI internal handle was not freed since v3.7.0 (-> memory leak)
      - Fixed OCI_LongWrite()   + OCI_CHARSET_WIDE charset mode : internal length passed to internal OCI calls was expressed in chars instead of bytes
      - Fixed OCI_TypeInfoGet() + OCI_TYF_TYPE : an Oracle error was raised when passing as type name a builtin system type like "SYS.RAW"
      - Fixed OCI_GetLastError() that could return NULL when errors occured in OCI_FetchXXX() calls (although the global error handler was correctly fired) 
      - Fixed OCI_DequeueGet() : a segfault happened if the queue payload was of type RAW 
      - Fixed OCI_DequeueFree() : internal structure member that hold the value set by OCI_DequeueSetConsumer() was not freed (memory leak)
      - Fixed OCI_MsgFree() : internal message ID allocated at enqueue time by OCI_EnqueuePut() was not freed (memory leak)
      - Fixed OCI_IterFree() : internal OCI_Elem handle was not freed for local collections resulting a small memory leak
      - Fixed OCI_EnqueuePut() and OCI_DequeueGet() : possible memory leak on Unix platforms + OCI_CHARSET_WIDE/OCI_CHARSET_MIXED charset mode
      - Fixed OCI_DequeueFree() : Internal OCI_Msg handle deallocation forgot to deallocate internal message ID resulting a small memory leak
      - Fixed OCI_SetPassword() and OCI_SetUserPassword() : in OCI_CHARSET_WIDE and OCI_CHARSET_MIXED builds, theses functions failed to change the password
      - Fixed OCI_LobRead2() and OCI_LobWrite2() that could block when using UTF8 through NLS_LANG environment variable
      - Fixed OCI_GetStruct() : structure padding was not handled properly
      - Fixed internal allocation of ROWID and UROWID internal buffers when using UTF8 through NLS_LANG environment variable

    * Miscellaneous changes

      - Added Exception type OCI_ERR_REBIND_BAD_DATATYPE if a rebinding call attempts to bind a datatype different than the initial one
      - Updated documentation about datatypes for rebinding
      - Added support for numeric subtypes in OCI_BindGetSubtype() + documentation update
      - Manual update of source code formatted with Uncrustify (wrong indentation of witch case and some variable initialization)
      - Pre built MS Windows 32/64bits Dlls are now built using MS Visual Studio 2010 Express (instead of MS Visual Studio 2008 Professional)
      - A MS Visual Studio 2010 Express solution and project has been added to the Windows package to rebuild the Dlls

      - Fixed possible segfault in OCI_Cleanup() if OCI_SubscriptionRegister() had been previouly called call unsuccessfully
      - Fixed internal array allocation when using OCI_ArraySetSize() called many times on the same prepared SQL statement

      - Fixed possible segfault in OCI_TimestampFromCTime() and OCI_TimestampFromCTime() if the libc function localtime() returns a NULL tm structure pointer
      - Fixed OCI_GetSessionTag() linkage : the function was internally named OCI_GetSessionData() instead of OCI_GetSessionTag() in connection.c
      - Fixed binding of date arrays : the introduction of OCI_XXXArrayCreate() in v3.6.0 has introduced a bug in dates array binding that would cause to pass NULL data for some elements of the array
      - Fixed some API naming inconstancy (lower/upper case)

        - OCI_ElemGetTimeStamp()      renamed to OCI_ElemGetTimestamp()
        - OCI_ObjectGetTimeStamp()    renamed to OCI_ObjectGetTimestamp()

        - Macros have been added for backward compatibility

        - Existing programs must be recompiled (in order to use this new version of ocilib) with no code change (as compatibility macros are provided)
  

2010-07-26 Version 3.7.0 Vincent Rogier vince.rogier@ocilib.net

    * Added support for Session Pools

      - Added support for Oracle Session pools :

        - This features has beed introduced in Oracle 9.2
        - For Oracle clients < 9.2, sessions are handled as regular connection pools

      - Renamed type OCI_ConnPool to OCI_Pool
      - Renamed all OCI_ConnPooXXX() calls to OCI_PoolXXX()
      - Added macros that maps old OCI_ConnPoolXXX() prototypes to OCI_PoolXXX() functions
      - Added new parameter 'type' to OCI_PoolCreate(). Possible values are

        - OCI_POOL_CONNECTION : creates a connection pool
        - OCI_POOL_SESSION    : creates a session pool

      - Added support for session pool tagging:

        - Added OCI_GetSessionTag()
        - Added OCI_SetSessionTag()

      - Added new parameter 'tag' to OCI_PoolGetConnection() 

      - Updated documentation:

        - Renamed page <module>, section <Connection pooling> to <Oracle pooling>
        - Added Information about session pooling

    * Extended fetch interface

      - Added OCI_GetStruct()
      - Added OCI_SetStructNumericType()
      - Added demo file fetch_struct.c

    * Improved Execute/Fetch performance with prepared statement

      - Improved by x15 fetch performance when executing and fetching prepared statements that return resultsets
      
          - Prior to v3.7.0 :

              - Before a prepared statement was re-executed, any previous resultset was freed
              - Then, once the statement was re-executed, the resultset was recreated by OCI_GetResultset()

          - From v3.7.0 :

              - The resulset is created only once and is just reinitialized before re-execution
              - Avoiding these unnecessary memory allocations/deallocations improves drastically the performances

    * Extended Array interface

      - Added OCI_SetBindAllocation()
      - Added OCI_GetBindAllocation()

         - Server handle is now allocated/deallocated when physical connection to server is created/freed
         - Session and context handles are now allocated/deallocated at logon/logoff time
         - Before theses handles were all allocated/deallocated when physical connection to server was created/freed
         - The old way could cause problems with old Oracle versions
      
      - Existing programs must be recompiled (in order to use this new version of ocilib) with no code change (as compatibility macros are provided)

    * Miscellaneous fixes
    
      - Fixed OCI_Object binding: 
    
         - Internal objects indicator structures were not binded properly
         - Even if the internal objects indicators were updated correctly, it was not seen by the server
         - Only the object itself nullity flag was sent to server
   
      - Fixed Batch error handling:
        
         - Some errors could not have be caught
         - Added checks in OCI_GetBatchErrorCount()

      - Fixed OCI_Element API :

         - Setting values with a standalone OCI_Element object associated to a standalone collection was broken
         - For collection of REFs, internal OCI_REf object was not freed by OCI_ElemFree()

      - Fixed OCI_Object members internal offset computation for 64bits builds
      - Fixed OCI_DirPathSave() that could not execute on a loaded stream

    * Improved Array interface
    
      - Arrays of non scalar datatypes (based on handles) previously had to be initialized element by element and could be time consuming
      - It is now possible to allocate arrays in one step and thus improve performance (especially with Oracle 11g), internal OCILIB structures and OCI handles are allocated in one step
      - Added OCI_DateArrayCreate()
      - Added OCI_DateArrayFree()
      - Added OCI_TimestampArrayCreate()

      - Depending on the database charset :
    
          - UTF8 : UTF8 strings are used for any text based binds or retrieved columns values
          - Other charsets : UTF8 strings can be used only with national strings (NCHAR/NVARCHAR/NCLOB)

    * Exented String support

      - Added OCI_BindSetCharsetForm() to enable the use of national charset on binded strings

    * Extended LOB API

      - It is now possible to specify for CLOB/NCLOB buffer lengths in characters and/or bytes for R/W operations

      - Various documentation updates
      - Modified OCI_LobRead() (and thus OCI_LobRead2()) to set a trailing null character
      - Replaced few left direct malloc() calls by OCI_MemAlloc()

         - available static libs in ocilib/lib32 : libociliba.a (ansi), libocilibm.a (mixed), libocilibw.a (unicode)
      - OCILIB prebuilt Dlls are still compiled with Microsoft Visual Studio
      
    * Miscellaneous internal changes

      - The object cache is now freed when a connection is terminated
      - Internal source file schema.c has been renamed to typeinfo.c
      - Internal source file dirpath.c has been added
      - Fixed some internal calls to please GDCC and its aliasing warnings with -Wall options
      
    * Documentation updates 

      - Added notes in OCI_ConnectionCreate() documentation for using External credentials
      - Added notes in OCI_BindArraySetSize() documentation for modifying input array number of elements between statement executions
      - All OCILIB headers and sources files (45 files - 43.000 lines) have been checked with spell checker to correct typos (my English remains not so good !)

    * Added some tracing features

      - Added OCI_SetTrace()
      - Added OCI_GetTrace()

    * Extended Object API

      - Fixed internal handling of null attributes (it has been rewritten)
      - Modified local (transients) objects creation. Now:

        * By default, all attributes are set to NULL
        * Non scalar attributes must be set by calling new functions OCI_ObjectSetXXX()

      - Added setters functions for non scalar object attributes

        * OCI_ObjectSetDate
        * OCI_ObjectSetInterval
        * OCI_ObjectSetTimestamp
        * OCI_ObjectSetColl
        * OCI_ObjectSetObject
        * OCI_ObjectSetFile
        * OCI_ObjectSetLob
        * OCI_ObjectSetRef

      - Added Miscellaneous Object functions

        * Added OCI_ObjectIsNull()
        * Added OCI_ObjectAssign()
        * Added OCI_ObjectGetType()

    * Extended Collection elements API

      - Fixed : OCI_ElemSetNull() that was only updating null indicator
      - Fixed : some functions were not checking input element handle nullity
      - Added checks on element type in OCI_ElemGetXXX() calls that throw an exception if the element type is not the same type as the one requested
      - Added setters functions for non scalar element base datatypes

        * OCI_ElemSetDate()
        * OCI_ElemSetInterval()
        * OCI_ElemSetTimestamp()
        * OCI_ElemSetColl()
        * OCI_ElemSetObject()
        * OCI_ElemSetFile()
        * OCI_ElemSetLob()
        * OCI_ElemSetRef()
   
    * Extended Bind informations

      - Modified : OCI_Bind handles are now public and can be retrieved for public information
      - Added OCI_GetBindCount()
      - Added OCI_GetBind()
      - Added OCI_GetBind2()
      - Added OCI_BindGetName()
      - Added OCI_BindGetType()
      - Added OCI_BindGetSubtype()
      - Added OCI_BindGetStatement()
      - Added OCI_BindGetData()
      - Added OCI_BindGetDataCount()
      - Added OCI_BindGetDataSize()
      - Added OCI_BindGetDataSizeAtPos()
      - Added OCI_BindSetDataSize()
      - Added OCI_BindSetDataSizeAtPos()
      - Added OCI_SetNull2()
      - Added OCI_SetNullAtPos2()
      - Extended OCIBindxxx() calls satefy : 

        * An error OCI_ERR_BIND_ALREADY_USED is now raised if the bind name or position is already binded to the statement
        * With the bind mode by position, provided bind indexes <= 0  and > OCI_BIND_MAX will cause an error OCI_ERR_OUT_OF_BOUNDS

      - Extended binds/registers limits :
 
        * OCI implements the SQL returning clause through binds operations
        * OCILIB wraps the result of the returning clause within OCI_Resultet object but has to use internal binds to create its resultset
        * Prior to v3.1.0, OCI_BIND_MAX (default 512) was the maximum of OCI_Bindxxx() including OCI_Registerxxx() that an OCI_Statement could handle
        * With v3.1.0, OCILIB can handle OCI_BIND_MAX user binds handle and OCI_BIND_MAX items in the returning clause

    * Fixed Unicode support for Unixes platforms

        * Unicode support for platforms with 4 bytes wchar_t was broken
        * Fixed configure script was setting bad charset macros
        * Fixed some internal buffer expansion functions

    * Miscellaneous public modifications

      - Added OCI_IsNull2()
      - Added OCI_ResultsetGetStatement()
      - Added OCI_BindArrayOfColls()
      - Added OCI_GetDataLength()
  
      - Added functions to retrieve OCI_Schema object from various OCILIB object bases on Oracle object type :

        * Added OCI_ObjectGetSchema()
        * Added OCI_CollGetSchema()
        * Added OCI_RefGetSchema()

      - Added runtime information about OCILIB builds modes :

        * Added OCI_GetImportMode()
        * Added OCI_GetCharsetMetaData()
        * Added OCI_GetCharsetUserData()

      - On Oracle versions >= 11g, OCILIB now sets the client driver layer name information

        * Value set to the constant OCILIB_DRIVER_NAME (by default "OCILIB") 
        * It is recorded in the system views V$SESSION_CONNECT_INFO and GV$SESSION_CONNECT_INFO

      - Modified ocilib demo to properly support MinGw and unix based unicode console output

    * Miscellaneous internal modifications

      - Added internal reference counter to OCI_Schema object 

        * Some OCILIB objects keep a pointer to some OCI_schema objects
        * If OCI_SchemaFree() was called, these objects were holding a reference to a freed block of memory and then accessing this reference could cause a segfault
        * Now OCI_SchemaFree() only frees an schema object if its reference counter is zero.
       
    * Miscellaneous fixes

      - OCI_FetchPrev() was returning FALSE if called directly after OCI_FetchLast() on resulsets with less then OCI_FETCH_SIZE rows (default set to 20)
      - if OCI_FetchXXX calls were returning FALSE, internal error flag was wrongly set to TRUE and OCI_GetLastError() could return a previous OCI_Error handle
      - OCI_Fetchxxx() functions could return TRUE even if the given SQL statement had some SQL conversion function that failed (like to_date(), etc..)
      - OCI_Getxxx() functions could cause a segfault called before any OCI_Fetchxxx() calls 
      - OCI_IsConnected() was always returning FALSE since v3.0.0
      - OCI_SchemaGet() with OCI_SCHEMA_TABLE was causing an ORA-24328 with Oracle 8 and 9 (working fine with Oracle 10) since v3.0.0
      - OCI_Execute() could raise an ORA-01483 if an OCI_Timestamp handle of type OCI_TIMESTAMP, initialized with OCI_TimestampSysTimeStamp() only, was binded to the statement
      - Fixed OCI_TimestampIntervalAdd() and OCI_TimestampIntervalSub() that might have raised errors with OCI_Timestamp handles of type OCI_TIMESTAMP
      - Fixed some preprocessor directives in oci_loader.h
      - Fixed OCI_Object reusability: internal sub object could not be freed when fetching next object and thus lead to memory leaks
      - Since v3.0.0, fetching LONG column with OCI_LONG_IMPLICIT mode was truncating data to its half length in Unicode and Mixed Builds 
      - Fixed some preprocessor directives for MinGw support
      - Fixed runtime loading of oracle libs that might have not worked if the provided OCI library location ended with an existing slash
      - Fixed internal OCI_CopyString() that might caused some troubles in Unicode builds 
      - Fixed some internal wrong arrays size used for memory allocation
      - Fixed some OCI_Date and OCI_Timestamp decode functions to work properly on big-endian platforms
      - Fixed string binding on mixed charset build iwth Oracle 8i
      - since v3.0.0, OCILIB source compilation was broken for oracle 8i
      - Fixed demo file output.c

2008-10-17 Version 3.0.1 Vincent Rogier vince.rogier@gmail.com

    * Miscellaneous fixes

      - Added checks (OCI_ERR_MIN_VALUE) on len parameter (len >=1) of OCI_LobRead(), OCI_LobApend(), OCI_LobWrite(), OCI_FileRead()
      - Compilation of ocilib source with MSCV6++ was broken (vsnprintf was not defined to _vsnprintf anymore)
      - Memory leak : internal bind data allocated for handling PL/SQL tables was never freed 
      - Memory leak : internal OCI_Elem object used by OCI_Coll was never freed
      - Memory leak : since v3.0.0,  OCI_Statement internal stored SQL command string was not freed anymore
      - Scrollable cursors : executing a non select query on a scrollable statement was causing an oracle error

    * The library has been re-tested with various test suites under valgrind to check memory handling and it is now clean !

      - Added OCI_ElemIsNull()    
      
    * Massive Library rewrite:

      - Update OCILIB Full Name from "OCILIB (C Wrapper for Oracle OCI)" to "OCILIB - C Driver for Oracle"
      - Split OCILIB main source file into 30 source files
      - All public and internal functions have been partially / largely reorganized / rewritten  
      - Miscellaneous code optimization, enhancement and cleanup
      - OCILIB source code compilation procudes zero warnings with highest warning settings of GCC and Microsoft C compiler
      - Note for GCC builds :

        * OCILIB static/shared libs are now bigger because of the split sources and the autotools default CFLAG set to "-g -02"
        * Stripping the library (using the command strip) will make it 3 times smaller.

      - Standardization of functions implementation:
      
        * 1 - Checks
        * 2 - Function code
        * 3 - thread error status (optionnal)
        * 4 - Single exit point
        
      - OCILIB main header file (ocilib.h) moved from folder ./src to folder ./include. 

        - For MS windows users, do not forget to update your compiler/IDE settings for include paths
 
    * Extended error handling

      - Updated section in the documentation (page <module>, section <Error handling>)
      - Major rewrite for the internal error handling code
      - Added support for thread contextual error handling
      
        * New Flag OCI_ENV_CONTEXT for OCI_Initialize()
        * Added OCI_GetLastError()
        
      - Enforced input parameter checking
      - Added OCI_GetSqlErrorPos() to retrieve the position error in a SQL statement
      - Now, OCILIB calls guaranties to raise an error in any situation where it should instead of just returning to caller as it was doing before
      - Added some Memory checking:

        * OCILIB now keeps counts of all internal allocated OCI handles, descriptors and objects
        * OCI_Cleanup() will throw an error in case of unfreed OCI object and returns FALSE
     
      - Modified return values for OCi_ErrorGetType() :
      
        * OCI_ERR_ORACLE : OCI calls error, SQL errors, ...
        * OCI_ERR_OCILIB : internal OCILIB and application logic errors
        
      - New exceptions are raised:
      
        * OCI_ERR_NONE                : "No error"
        * OCI_ERR_NOT_INITIALIZED     : "OCILIB has not been initialized"
        * OCI_ERR_LOADING_SHARED_LIB  : "Cannot load OCI shared library (%lib_name%)"
        * OCI_ERR_LOADING_SYMBOLS     : "Cannot load OCI symbols from shared library"
        * OCI_ERR_MULTITHREADED       : "OCILIB has not been initialized in multithreaded mode"
        * OCI_ERR_MEMORY              : "Memory allocation failure (type %type_name%, size : %block_size%)"  
        * OCI_ERR_NOT_AVAILABLE       : "Feature not available (%feature_name%) "
        * OCI_ERR_NULL_POINTER        : "A null %type_name% has been provided"
        * OCI_ERR_NOT_SUPPORTED       : "Oracle datatype not supported (sqlcode %oracle_code%) " (currently only REFs are not supported)
        * OCI_ERR_PARSE_TOKEN         : "Unknown identifier %token% while parsing SQL"
        * OCI_ERR_MAP_ARGUMENT        : "Unknown argument %arg_code% while retreiving data"
        * OCI_ERR_OUT_OF_BOUNDS       : "Index %value% out of bounds. Must be between %min% and %max%"
        * OCI_ERR_UNFREED_DATA        : "Found %nb% unfreed %data_type%"
        * OCI_ERR_MAX_BIND            : "Maximum number of binds (%limit%) already reached" (currently 512)
        * OCI_ERR_ATTR_NOT_FOUND      : "Object attribute '%name%' not found"

        * OCI_ERR_STMT_STATE          : "Unable to perform this operation on a %stmt_state% statement"
        * OCI_ERR_STMT_NOT_SCROLLABLE : "The statement is not scrollable"

      - The exception OCI_ERR_NOT_INITIALIZED is only available with OCI_GetLastError(), even 
        if OCI_ENV_CONTEXT is not used with OCI_Initialize(), and is raised when calling OCI_XXXXCreate()
        to allocate OCILIB handles before any call to OCI_Initialize()

    * Extended implicit datatype conversions

      - Added OCI_SetDefaultFormatNumeric()
      - Added OCI_GetDefaultFormatNumeric()
      - Added OCI_SetDefaultFormatDate()
      - Added OCI_GetDefaultFormatDate()
      - Modified OCI_SetFormatDate() and OCI_GetFormatDate() that now are macro for compatibility with older code
      - Added support for implicit conversion:

        * String columns can be retrieved as numeric data
        * OCI_GetString() and OCI_GetString() can return string data whatever the real type of the column (except for Object, Collection and Cursor based columns)

    * Improved internal numeric datatypes handling

      - Modified : public OCILIB datatype OCI_CDT_INTEGER and OCI_CDT_DOUBLE has been replaced by one datatype : OCI_CDT_NUMERIC
      - Modified : Now, all fetched numeric columns are internally mapped to OCINumber OCI type and to public type OCI_CDT_NUMERIC
      - Modified : Much cleaner, compact an easier code for handling OCI_GetXXXX() calls for all numeric types
                    
    * Extended Date, timestamp and interval support

      - Added OCI_TimestampGetDateTime()
      - Added checks for securing input integer pointer :

        * OCI_DateGetTime(), OCI_DateGetDate(), OCI_DateGetDateTime()
        * OCI_TimestampGetTime(), OCI_TimestampGetDate(), OCI_TimestampGetDateTime(), OCI_TimestampGetTimeZoneOffset()
        * OCI_IntervalGetDaySecond(), OCI_IntervalGetYearMonth()

    * Extended OCILIB documentation that has been updated and some precisions has been added:

      - Added    : page <module> - section <PL/SQL support> with new code examples
      - Added    : page <module> - section <Collections (Varrays and Nested Tables> with new code examples
      - Extended : page <module> - section <Error handling> for thread contextual error handling
      - Extended : page <module> - section <Fetching data> for scrollable cursors and string conversions
      - Extended : page <module> - section <Library objects and datatypes>) for supported datatypes
      - Updated  : page <module> - section <Charset support>
      - Modified : page <module> - section <Build Options> content moved to page <module> - section <Installing OCILIB>
      - Updated  : miscellaneous changes
         
    * Miscellaneous changes

      - Modified : up to 110 various functions prototypes have been modified to change the type of the return value or some parameters from int -> unsigned int
      - Modified : OCI_GetResultset() returns now the first resultset if it exists instead of creating a new one
      - Modified : OCI_SetNull() and OCI_SetNullAtPos() : now indexes and positions start at 1
      - Modified : OCI_BIND_MAX (maximum number of binds for a statement) is now 512 by default instead of 256
      - Modified : OCI_BindArraySetSize() : param nbelem type modified from 'int' to 'unsigned int'
      - Modified : OCI_HashGetEntry() : now indexes and positions start at 1
      - Modified : Rearranged internal structures to respect alignment and avoid padding
      - Modified : OCI_HashGetEntry() : now indexes and positions start at 1
      - Modified : return value in case of failure for OCI_TransactionGetMode() [OCI_ERROR->OCI_UNKNOWN] and OCI_TransactionGetTimeout() [OCI_ERROR -> 0]
      - Modified : OCI_GetColumnXXX() calls are now renamed to OCI_ColumnGetXXX() and old prototypes are maintained as macros for backward compatibility
      - Added    : OCI_StatementGetConnection()
      - Added    : OCI_ColumnGetSchema()
      - Added    : OCI_ColumnGetSubType()
      - Added    : support for MSVC6++/unicodes builds

        * Inclusion of wchar.h is now done in extern C++ block for MSVC6++ and cpp applications
        * swprintf() is mapped to _snwprintf() because VC6 C-library is not ISO C compliant
 
    * Fixed some Connection pools problems
 
      - Fixed : Connection pools : every call to OCI_ConnPoolGetConnection() was allocating internal data instead of using existing ones.
      - Fixed : Memory leak : internal connection transaction handle was never freed
      - Fixed : OCI_ConnPoolCreate() : parameter 'incr_con' was not used (value '1' used instead)

    * Fixed some PL/SQL table problems
 
      - Fixed : PL/SQL table pure IN binds was causing PL/SQL error when the table parameters was accessed by PL/SQL procedures
      - Fixed : Passing the value 1 for array size in PL/SQL tables binds caused an ORA-06550
  
    * Fixed Oracle Long fetching

      - Segmentation fault was happening if a select contained a LONG column + other columns
      - Unnecessary reallocation of internal LONG buffers was done at every internal fetch call (by default every 20 rows)
      - When using OCI_LONG_IMPLICIT (LONG mapped to VARCHAR), strings returned by OCI_GetString() might not have their final null character
       
    * Modified GNU configure scripts

      - Added    : For GNU builds added configure option --with-custom-loader for platforms that are not using '-ldl' (if using option --with-oracle-linkage=runtime)
      - Fixed    : Some configure options were broken
      - Modified : Added some checks and some outputs

    * Miscellaneous fixes

      - Fixed : Replaced any references of 'long' C type with 'int' C types in unix wchar internal conversion functions (on 64bits platforms, 
                sizeof(long) is 8 bytes so it lead to some buffer bad alignment)
      - Fixed : Second parameter 'ptm' of OCI_DateToCTime() and OCI_TimestampToCTime() was not mandatory as it should have been
      - Fixed : Unicode buffer conversion : Internal OCI_StringLength() could not work properly on some architectures
      - Fixed : Binding 64bits integers was not working properly (wrong internal flags)
      - Fixed : OCI_ObjectGetShort() and OCI_ObjectGetUnsignedShort() were missing in ocilib.c
      - Fixed : the header "limits.h" was not included in ocilib.h and on some configurations the support of 'long long' could not be detected
      - Fixed : CLOBs read/writes on OCILIB Unix/Unicode builds could not work properly (wrong buffer passed to OCI)
      - Fixed : OCI_SetUserData() was not exported
      - Fixed : return value of the declaration of OCI_GetVersionConnection() was wrong (boolean instead of unsigned int)
      - Fixed : OCI_ServerEnableOutput() and OCI_ServerDisableOutput() prototypes did not have the OCI_API call convention (for MS builds)
      - Fixed : OCI_ObjectGetString() prototype was returning wrong type 'mtext *' instead of 'dtext *'

    * Updated main demo application

      - Added : Example for scrollable cursors and collections (varrays and nested tables)
      - Fixed : some bad cast could lead buffer bad filling in mixed charset build

    * Fixed Mixed charset builds (OCI_CHARSET_MIXED ONLY)

      - Fixed : OCI_ObjectGetString() and OCI_ObjectSetString() were misunderstanding string buffers
      - Fixed : OCI_ServerEnableOutput() was not allocating enough memory to hold output buffer lines
      - Info  : OCILIB functions using the OCI functions OCIStringPtr() and OCIStringAssignText() have a limitation on mixed charset builds :

        * In mixed builds, OCILIB Strings (dtext *) used for handling user data are wchar_t strings, but the underlying OCI API 
          understands theses strings as not unicode but ansi or other encoding 
        * So, there is now, when building OCILIB with OCI_CHARSET_MIXED, an internal conversion to/from ANSI data when using :
          
          - OCI_ObjectGetString() and OCI_ObjectSetString()
          - OCI_ElemGetString() and OCI_ElemSetString()

2008-07-24 Version 2.5.1 Vincent Rogier vince.rogier@gmail.com

    * Fixed : OCILIB builds with Runtime loading of OCI shared library activated

      - Loading dynamically OCIMutexXXX() functions was broken with v2.5.0
      - Runtime loading of the OCI shared library on Unix-like platforms was broken with v2.5.0

    * Fixed Unicode builds: 

      - Binding C Unicode strings (wchar_t *) to PL/SQL tables of char/varchar was throwing an PLS-00418 error 
      - The internal buffer expansion (for Unix-like platforms where wchar_t is 4 bytes) could mess up the data for arrays of string binds
      - OCI_ConnPoolGetConnection() could return NULL with an Oracle 8i client if OCILIB was built with an OCI version >= 8 or with OCI_IMPORT_RUNTIME option

2008-07-21 Version 2.5.0 Vincent Rogier vince.rogier@gmail.com

    * Added support for PL/SQL tables (PL/SQL arrays)

      - Bind (input, output) C arrays to PL/SQL using OCI_BindArrayOfxxx() functions
      - All the OCI_BindArrayOfxxx() functions take now an extra param : the size of the array for PL/PL/SQL table
      - For regular array interface bind, pass 0 for the array size which is set by OCI_BindArraySetSize() 

    * Extended Date, timestamp and interval support

      - Added OCI_DateGetDateTime()
      - Added OCI_DateSetDateTime()
      - Added support for converting C types (time_t, tm) to/from OCI_Date and OCI_Timestamp :

        * Added OCI_DateFromCTime()
        * Added OCI_DateToCTime()
        * Added OCI_TimestampFromCTime()
        * Added OCI_TimestampToCTime()

      - Date, timestamp and interval can now be create outside a database connection:
            
        * To create a connection independent object, pass a NULL OCI_Connection pointer to OCI_DateCreate(), OCI_TimestampCreate() and OCI_intervalCreate() functions
        * Keep in mind that using a connection pointer is still recommended because it is checking that the server is able to handle these datatypes

      - Fixed OCI_TimestampIntervalAdd(), OCI_TimestampIntervalSub() : 

        * If the timestamps type was not OCI_TIMESTAMP_TZ, an error occured
        * Now, these functions changes the timestamps types for OCI raw call and set it back before returning
        * Possible bug OCI -> Investigating with Oracle support 

    * Extended OCI_Connection handle attributes

      - Added OCI_IsConnected()
      - Added OCI_SetUserData()
      - Added OCI_GetUserData()

      - See section in the documentation (page <module>, section <Threads and mutexes>)
      - Added OCI_ThreadKeyCreate()
      - Added OCI_ThreadKeyGetValue()
      - Added OCI_ThreadKeySetValue()

    * Extended OCILIB documentation:

      - Added "Installation" page
      - All examples have been checked, updated, corrected and extended
      - All examples are now provided as full programs sources code

    * Added more demo source code

      - 26 full application sources codes are now provided in the ocilib/demo directory
      - Theses application examples are now integrated in the OCILIB documentation
 
    * Misc:

      - Added const qualifier to return values of OCI_HandleXXX() calls
      - Fixed parameter checking in some OCI_ObjectXXX() calls

      - DLL projects for VS2005 and 2008 are provided
      - DLL are compiled with C99 long long type enabled (as before, it is just a reminder)
      - Removed compiled demo binaries from the package to reduce archive size that was increased with 64bits binaries

    * Extended Error handling

      - Added    : OCI_Initialize() with OCI runtime loading build option raises now an error if OCI shared library cannot be loaded
      - Added    : OCI_Initialize() with OCI_CHARSET_UNICODE and Oracle client 8 raises now an error (Oracle 8i cannot handle Unicode metadata strings)
      - Added    : OCI_xxxFmt() calls raise now an error if a format identifier is invalid
      - Added    : OCI_Immediatexxx() calls raise now an error if the type value is not an OCI_ARG_XXX constant
      - Modified : Internal error functions (added OCI_ErrorGeneric())

    * Modified OCI_Immediate() and OCI_ImmediateFmt()

      - Extended type safety (public interface modifications) :

        * For output placeholders, you have to pass NOW one of the OCI_ARG_xxx constant to tell OCILIB the type the placeholder pointer
        * Every placeholder pointer has to be preceded by the type constant
        * Example : OCI_Immediate(st, "select int_col, str_col from my_table", OCI_ARG_INT, &my_int, OCI_ARG_TEXT, my_text);
        * Output placeholders : support NOW for short, unsigned short, unsigned int, big_int, big_uint
        * Updated section in the documentation (page <module>, section <Formatted functions>)
  
      - Fixed    : For OCI_ImmediateFmt(), temporary Statement object was not freed (line commented in 2.3.0 with no reasons !)
      - Fixed    : If internal OCI_GetString() returned NULL, a segmentation fault could happen 
      - Modified : No check was done on scalar C type placeholder pointers nullity (possible source of seg fault)
      - Modified : OCI_Date handling was not updated with v2.3.0 modifications
      - Modified : OCI_Long and OCI_Statement handling was not removed as stated in the changelog of v2.3.0
      - Modified : Factorization of the 2 functions code

      - Added new identifiers :

        * '%u'  : unsigned int
        * '%hi' : short
        * '%hu' : unsigned short
        * '%li' : big_int
        * '%lu' : big_uint

      - Fixed : OCI_LobAppendLob() was not updating internal current offset position
      - Fixed : OCI_ParseSqlFmt() : OCI_interval * variable was not checked for nullity
      - Fixed : OCI_Initialize() with runtime loading mode : oracle 11g detection was broken (missing 'else' keyword)
      - Fixed : OCI_GetResultset() : selecting unsupported REF datatype was throwing 2 errors instead of one.
      - Fixed : OCI_GetDate()    + client Oracle 11g + "Return into" clause    : the OCILIB workaround for Oracle bug #3269146 was not working properly
      - Fixed : OCI_BindString() + client Oracle 8i  + OCI_CHARSET_MIXED build : setting internally OCI_ATTR_CHARSET_FORM (since v2.0.0) caused a crash with Oracle 8.1.7.O (OCI bug ?)
      - Normalization of few Function Names :

        * OCI_CreateTransaction() -> OCI_TransactionCreate()
        * OCI_FreeTransaction() -> OCI_TransactionFree()
        * OCI_CreateHashTable() -> OCI_HashCreate()
        * OCI_FreeHashTable() -> OCI_HashFree()

    * Extended "Formatted" functions support :

      - Added support for OCI_Timestamp (<%p>) and OCI_Interval(<%v>)

    * Public interface (IMPORTANT CHANGES)

      - OCI_Initialize() :

        * New flag : OCI_ENV_THREADED
        * Up to v2.2.0, OCILIB was internally initializing OCI in threaded mode (even for non threaded applications)
        * With  v2.3.0, applications HAVE TO SET EXPLICITLY the flag OCI_ENV_THREADED for multithreaded applications

      - Normalization of few Function Names :

        * OCI_CreateConnection() -> OCI_ConnectionCreate()
        * OCI_FreeConnection() -> OCI_ConnectionFree()
        * OCI_CreateStatement() -> OCI_StatementCreate()
        * OCI_FreeStatement() -> OCI_StatementFree()

      - Added Macro for existing code compatibility

    * Bug fixes :

      - OCILIB_MINOR_VERSION was not updated
      - A segmentation fault could happen when fetching Long column
      - If an OCI_Statement object or its internal handle could not be allocated, the entry was not removed from the connection statements list
      - Binding and fetching Unicode strings on national character columns: non ansi characters (code points) were badly converted (Now, it uses national charset form for conversion)
      - OCI_LobErase() : Offset value was wrongly used (shifted by 1) and could cause an error if set to zero
      - OCI_Immediate() and OCI_ImmediateFmt() :

        * Passing OCILIB objects for output result led to crash because of assignment of out-of-scope object pointers
        * Now, pass the OCILIB object handle, NOT the handle address
        * Now, OCI_Long, OCI_Statement are not handled

    * Miscelleanous

      - Added OCI_ReleaseResultsets() : optional call to release resultsets
      - OCI_SetPrefetchSize() and OCI_SetPrefetchMemory() : internal value is now set only is OCI call succeed
      - Internal connection rewrite for handling Connection pool
      - Renamed few function parameters + documentation updates
      - Unicode strings are now converted into database using national charset form
      - OCI environment handle : 

        * Up to v2.2.0, every connection object holded an environment handle
        * Now, there is an unique environment handle associated to the internal OCI_Library object

2008-03-19 Version 2.2.0 Vincent Rogier vince.rogier@gmail.com

    * Public interface

      - Added OCI_SetPrefetchMemory() (see documentation)
      - Added OCI_GetPrefetchMemory()
      - Added OCI_SetPassword()
      - Added OCI_Break()
      - See new section in the documentation (page <module>, section <Aborting long operations>)
      - Modified few functions prototypes with no parameters -> from f() to f(void) for strict ansi C support 
      - Added 'const' qualifier to nearly all string parameter and string return values

    * Extended OCI_GetString() :

      - Modified : Implicit conversion from double uses now '%f' instead of '%g'.
      - Added support for OCI_Timestamp, OCI_Interval and implicit conversion

    * Fixes

      - Memory leak : If a statement that has returned a resulset is re-executed directly with OCI_Execute() (without any parse step), the previous resultset was not freed
      - Some statements attributes (fetch size, pre-fetched size, bind mode, long mode, long size) where reinitialized at every SQL parsing. Now they are persistent.
      - Constants OCI_FETCH_SIZE, OCI_PREFETCH_SIZE values were set to Oracle default values and were not assigned at statement creation time.
        So, if the library was rebuilt with different values, the modified values where not applied! Now, theses attributes are internally set internally when a statement is created
      - Now server version is initialized when the connection object is created (some tests for some features support could failed)

    * Modifications

      - Added support for OS authentification by passing NULL user and NULL password to OCI_CreateConnection()
      - Modified default date format for implicit conversion (DD/MM/YYYY -> YYYY-MM-DD)
      - Modified OCI_BindXX() calls : if bind mode is OCI_BIND_POS, the position used is now the given bind name (:1, :2, ...) instead of the internal bind object index
      - Modified OCI_CreateConnection() : it returns now NULL id OCI_Initialize() has not been called
      - Reintroduced support for native C++ compilation of OCILIB

    * Miscellaneous

      - Validation of LabWindow/LabView compilers
      - change email -> vince.rogier@gmail.com
      - Modified demo application: tests are now grouped in series of functions
      - Object support in Unicode builds : Oracle confirmed the bug when setting objects attributes (bug #6885036 on Metalink)

2008-03-04 Version 2.1.0 Vincent Rogier vince_rogier@yahoo.fr

    * Added public retrieval of internal OCI handles :

      - See new section in the documentation (page <module>, section <Using OCI Handles directly>)
      - OCI_HandleGetEnvironment()
      - OCI_HandleGetContext()
      - OCI_HandleGetServer()
      - OCI_HandleGetError()
      - OCI_HandleGetSession()
      - OCI_HandleGetTransaction()
      - OCI_HandleGetStatement()
      - OCI_HandleGetLob()
      - OCI_HandleGetFile()
      - OCI_HandleGetDate()
      - OCI_HandleGetTimestamp()
      - OCI_HandleGetInterval()
      - OCI_HandleGetObject() 

    * Extended Hash Tables support :

      - See updated example in the documentation (page <module>, section <Hash tables>)

    * Added support for Lobs larger > 4 Go (Oracle 10g)

      - See updated section in the documentation (page <module>, section <Internal Large Objects (LOBs)>)
      - Added type lobsize_t (unsigned int or unsigned long long depending platform and compiler)
      - Modified OCI_Lob and OCI_File APIs to change lob size and offset type from unsigned int to lobsize_t 
        
    * Extended Oracle versions support

      - Added OCI_GetVersionConnection()
      - Building OCILIB with versions of Oracle < 10g and OCI_IMPORT_LINKAGE option could fail because :

        * BINARY FLOAT and BINARY DOUBLE (introduced in 10g) type references were not excluded from 8i and 9i builds
        * Some Timestamp and Interval (introduced in 9i) code portions were not excluded from 8i builds

      - Modified Oracle version detection
      - Rewritten conditional code compilation directives for handling correctly all versions of Oracle (8i -> 11g)
      - The library has been through series of tests on the following environments:

          * Servers : 10.2.0.1.0,  8.1.7.0.0           
          * Clients : 11.1.0.6.0, 10.2.0.1.0, 9.2.0.1.0, 9.0.1.0.1

      - few errors were encountered but always linked to Oracle known bugs identified on Metalink : nclobs on 8i, intervals on 9i, Full Unicode handling on 9i
      - Known issues that are currently being investigated: 

        * Oracle 8i only + "mixed charset" build : read/write on a CLOB fetched from a "return into" inserts '\0' between characters (looks like double unicode expansion..)

    * Modified Error handling

      - Added OCI_ErrorGetType()
      - Removed error messages prefixes "(OCI_xxx) - "
 
    * Fixed :

      - OCI_RegisterDate() caused OCI_Execute() to crash with Oracle < 10g. It is a known Oracle bug (metalink id #3269146 : OCIBindDynamic() with SQL_ODT).
      - OCI_RegisterDate() works nows on version < 10g (using SQLT_ODT for 10g and SQLT_DAT for 8i and 9i)
      - OCI_LobAppendLob() caused an ORA-24805 on Oracle 8.1.x only
      - OCI_xxxxToText() functions now initialize output buffers even on failure
  
2008-02-16 Version 2.0.0 Vincent Rogier vince_rogier@yahoo.fr
 
    * Added Support for Unicode build on Unix-like systems

      - Now, Unicode is correctly handled on Unix systems (4 bytes wchar_t)

      - OCI_BindArrayOfObjects()
      - OCI_RegisterObject()
      - OCI_GetObject()
      - OCI_GetObject2()
      - Known issue : OCI function internally used to set attributes values is causes a crash on Unicode Build
      - So, DO NOT USE OCILIB Object API in Unicode build until i have sorted that with Oracle support

    * Added National attribute (charsetform) support

      - added OCI_GetColumnCharsetForm()
      - added OCI_Lob type OCI_NCLOB
      - added national charset support for binding, defining and lob manipulation

      - added OCI_GetColumnLeadingPrecision() for interval
      - modified OCI_GetColumnPrecision() return non zero only for numeric/float

    * Added support for SYSDBA, SYSOPER session modes

      - modified OCI_CreateConnection() that takes a new extra parameter to manage the session mode
      - added OCI_GetSessionMode()

    * Added support for BINARY FLOAT and BINARY DOUBLE (introduced with Oracle 10g)
 
    * Modified Input string buffer length parameters:

      - Parameter 'len' of OCI_LobRead(), OCI_LobWrite(), OCI_LobAppend(), OCI_LongRead(), OCI_LongWrite() is now :

        * Number of bytes for OCI_BLOB and OCI_BLONG
        * Number of characters for OCI_CLOB/OCI_NCLOB and OCI_CLONG

      - OCI_LobGetLength(), OCI_LobGetOffset() and OCI_LongGetSize() return now the length/offset expressed :

        * In bytes for OCI_BLOB and OCI_BLONG
        * In characters for OCI_CLOB/OCI_NCLOB and OCI_CLONG

      - Parameter 'size' of OCI_DateToText(), OCI_TimestampToText(), OCI_TimestampGetTimeZoneName(), OCI_IntervalToText is now :

        * Number of characters

      - Fixed : If OCI_RegisterXXX() calls were made in a different order than the variable list in the returning 
        clause, resultset columns were created in the wrong order and leaded to type mismatch

    * Miscellaneous modifications:

      - OCI_Initialize() takes a new param for future environment options and extra modes (by default OCI_ENV_DEFAULT)

       (or array element) is NOW :
            
        * UNDERSTOOD WITHOUT the zero terminal terminator.
        * EXPRESSED in CHARACTERS

      - So, for OCI_BindString() :

        * if the string is char    str[31], pass 30 as len instead of 31 in earlier version
        * if the string is wchar_t str[31], pass 30 as len instead of 62 in earlier version

      - So, for OCI_BindArrayOfStrings() :

        * if the string is char    str[10][31], pass 30 as len instead of 31 in earlier version
        * if the string is wchar_t str[10][31], pass 30 as len instead of 62 in earlier version

        indicating the size in character and not in bytes

      - Prototypes for OCI_BindArrayOfInts(), OCI_BindArrayOfDoubles(), OCI_BindArrayOfStrings() changed :

        * For scalar C types (int, double and char*), the 'data' parameter was changed from type** to type* in
          order to avoid compiler warnings and casts

    * Miscellaneous fixes

      - OCI_Immediate() and OCI_ImmediateFmt()  : timestamp and interval params ARE STILL NOT parsed from 
       formatted query
      - Some NUMBER columns were wrongly mapped to C int type instead of double
      - OCI_Long internal structure could not be freed for an standalone instance
      - Demo application for handling string in unicode and mixed mode
      - OCI_LobErase : added size checking (oracle error with size = 0 on an empty lob)

      - Fixed    : OCI_Date * Array binding : wrong memory allocation size
      - Fixed    : Strings Array binding did not adjust the buffer size depending on the sizeof(dtext) and could
