2  
3 < 1. IBExtract: Identity columns - add additional check for null column for generator name.
3 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
4 >   with a Firebrid 3 client library.
5  
6 < 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
7 <   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
8 <   information). However, this is also a very useful mechanism for returning updated computed by
9 <   column values. Values returned as a result of executing an Insert or Update statement
10 <   replace existing values in the current row for each corresponding column.
6 > 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
7 >    If a client library path is not explicitly provided and the FIREBIRD environment
8 >    variable is set then the directory given by this variable and any 'lib' subdirectory
9 >    are searched for the Firebird client library. Only if none is found, is the default
10 >    client library used.
11  
12 <   Previously, if a dataset's select query included read only (computed by) fields then
12 <   an automatic row refresh was performed after an insert or update query had been processed,
13 <   irrespective of the setting of the "ForcedUpdates" property. This has changed such
14 <   that an automatic refresh is no longer performed if an insert or update query contains
15 <   a returning clause that updates one or more fields on the current row. A full row
16 <   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
17 <   field values and the select query contains read only fields. Use of Insert/update
18 <   returning should be significantly more efficient than executing a refresh query.
12 > 3.  IUtil.FormatStatus now used to format error messages when using new API
13  
14 <   This behaviour change is intended to be backwards compatible and there should be no need to change
21 <   existing programs, other than to improve performance by using the new capability.
14 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
15  
16 < 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
17 <   they are called when the dataset row is being deleted, there is no value in
18 <   updating the current record from the query result. Instead, a new event handler
19 <   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
20 <   an OnDeleteReturning event handler is provided then it is called with the IResults returned
21 <   by the query. The event handler can then interrogate the query results and
29 <   perform whatever action is necessary. For example to confirm, to the user,
30 <   the deletion of a row with the returned values.
16 > 5.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
17 >    returned using GetAsString and the string codepage is UTF8, the string is truncated so
18 >    that the byte length corresponds to the number of characters specified for the column.
19 >    SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
20 >    correct behaviour but may affect some implementations that relied upon automatic
21 >    trimming of trailing white space.
22  
23 < 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
24 <   any Computed By or Identity Columns. The IBTables example has been updated to
25 <   illustrate the computation of the employee Full Name on update.
23 > 6.  New IFirebirdAPI Calls:
24 >      function GetClientMajor: integer;
25 >      function GetClientMinor: integer;
26  
36 5. TIBTable: The GeneratorField property is now published.
27  
28 < 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
39 <   When InsertSQL is generated, the Identity columns are not included in the list of values to
40 <   be inserted. A RETURNING clause is added to the insert statement to return the value of
41 <   each Identity column after the insert is executed.
28 > FBINTF Change Log  version          (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +0100
29  
30 < 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
31 <   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
45 <   Insert..Returning clause.
30 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
31 >   case sensitive
32  
33 < 8. TIBGenerator: small performance improvement by not preparing query each time
48 <   a new value is generated.
33 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
34  
35 < 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
35 > 3. New API Calls:
36 >        IColumnMetaData.GetStatement
37 >        IColumnMetaData.GetTransaction
38 >        ISQLData.GetStrLength
39 >        IResults.GetStatement
40 >        IAttachment.OpenBlob (using Blob metadata)
41 >        IAttachment.OpenArray (using array metadata)
42  
43 < 10. Property editors will now sync table name to a System Table when "Include System
53 <    Tables" is selected and the query is for a System Table.
43 > 4. FBMessages: removal of unused messages
44  
45 < 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
56 <    values are no longer converted to milliseconds from TDateTime and then back again
57 <    to TDateTime (the conversion to milliseconds is the default TDataset approach).
45 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
46  
47 < 12. Property Editors handling of Stored Procedures.
60 <    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
61 <      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
62 <      query).
63 <    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
47 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
48  
49 < 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
66 <    can be used to select a package. If non-empty, the stored procedure name is
67 <    expected to be a stored procedure defined in the specified package and the
68 <    generated SQL will be as required for a stored procedure located in a package.
49 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
50  
51 < 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
52 <    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
72 <    which a stored procedure can be selected. With no package name selected, non-package
73 <    stored procedures are listed.
51 > 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
52 >   where the second character of the parameter name is a numeric.
53  
54 < 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
55 <    for password on reconnect.
54 > 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
55 >   This returns the isc_version connection information as one or more lines.
56 >   This is the same information as returned by isql with the -z option.
57  
58 < 16. IBDatabase: use IAttachment for connection default character set id, code page
59 <    and character set name.
58 > 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
59 >   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
60 >   compiler option then the Firebird 3 API is no longer compiled in.
61  
62 < 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
82 <    DB info lookups"
62 > 4. IColumnMetaData: new method.
63  
64 < 18. IBExtract: now supports DDL Triggers.
64 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
65 >                        dfDateTime,   {SQL DATETIME}
66 >                        dfTime);
67  
68 +   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
69  
70 < IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
70 >   This returns the max. number of characters returned by the "AsString" method
71 >   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
72  
73 < 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
74 <   changes.
73 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
74 >     CaseSensitiveParams: boolean = false
75  
76 < 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
77 <   Bug could result in truncated multi-byte character set values.
76 >   If this argument is set to true then SQL parameter names are assumed to be case
77 >   sensitive and must be referenced (using ISQLParams.ByName) using the case
78 >   sensitive name.
79  
80 < 3. Changes consequential on moving fbintf character set utility functions from
81 <   IFirebirdAPI to IAttachment.
80 > 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
81 >   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
82 >   .AsCurrency) and then subsequently to update the value to a non-numeric string
83 >   using .AsString.
84  
98 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
85  
100 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
101   results in autocomplete ignoring prefix text.
86  
87 < 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
104 <   entering a new name into the text box.
87 > FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
88  
89 < 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
107 <   Firebird rather than recomputing it.
89 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
90  
91 < 8. Property Editor positioning tidy up: All IBX Property editors should now be
92 <   screen centre. Previously some were "poDesigned" which may be inappropriate
111 <   for multi monitor desktops.
91 > 2. Restrict IsMultiThread check to Unix only for compatibility with
92 >   https://bugs.freepascal.org/view.php?id=30535
93  
94 < 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
94 > 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
95 >   named parameters and is intended to avoid problems with (e.g.) Execute Block
96 >   and processing internal parameters as statement parameters.
97  
98 < 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
99 <    a transaction and always reset the object.
98 > 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
99 >   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
100  
101 < 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
101 > 5. New function added to IB.pas
102  
103 < 13. TIBXScript: Allow for override of database filename in Create Database statements.
103 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
104  
105 < 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
106 <    to a gbak format archive.
105 >   This allows a Firebird Library to be loaded from an explicit path. use the
106 >   IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
107 >   the library. It is possible to load Firebird libraries from different locations
108 >   simultaneously, each with a distinct IFirebirdAPI.
109  
110 < 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
110 > FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
111  
112 < 16. IBLocaldb: Drop database if error creating an empty database.
112 > 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
113 >   program compiled with -CR command line switch.
114  
115 < 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
116 <    unless selected node not in current dataset.
115 > 2. IServiceManager additions (informational):
116 >    function getProtocol: TProtocol;
117 >    function getPortNo: AnsiString;
118  
119 < 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
120 <    to TIBCustomService, and IBlocalDB code tidy up.
119 > 3. IServiceManager improved error handling. Interfaces changed:
120 >    function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
121 >    function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
122 >    function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
123  
124 < 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
125 <    behaviour due to uninitialised variable.
124 > 4. IAttachment addition (informational)
125 >    function GetSecurityDatabase: AnsiString;
126  
127 < 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
128 <    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
127 > 5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
128 >   thus now returns accumulated stats for a select statement from opening a cursor
129 >   up to the last fetch.
130  
131 < 21. IBSQL: When Database changed ensure that all resources are freed.
131 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
132 >   the problem.
133  
134 < 22. IBCustomDataset: When database changed ensure that queries an unprepared.
134 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
135 >   replaces deprecated "comp" type.
136  
137 < 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
146 <    * Line Wrap on SQL Token boundaries (on user command)
147 <    * auto-complete table names in drop down list of table names
148 <    * Double click on tablename or field name adds to SQL text
137 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
138  
139 < 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
139 > 11. URL Connection Strings: inet4 and inet6 now recognised.
140  
141 < 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
153 <    TVariantArray. Seems to avoid memory corruption in Windows (probably a
154 <    workaround for a problem in fpc 3.0.4 win64).
141 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
142  
143 < 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
143 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
144  
158 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
145  
146 < IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
146 > FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
147  
148 < 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
163 <   include remote system name.
148 > 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
149  
150 < 2. TIBExtract: No longer include comment header and COMMIT statement for empty
151 <   tables when data included in output.
150 > 2. IAttachment: add two new methods
151 >     function HasDefaultCharSet: boolean;
152 >     function GetDefaultCharSetID: integer;
153  
154 < 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
155 <   and timing information to be written to stdout. This may be used to locate
156 <   performance bottlenecks.
154 >   These return, respectively, true if a connection default character set was
155 >   specified and the character set id of the connection default character set.
156 >   The DefaultCharSetID is cached when the connection is opened and hence does not
157 >   require a database lookup.
158  
159 < 4. SQLParser: only call "OnChanging" event handler when value is different.
159 > 3. Avoid exception when a text blob is a stored procedure parameter.
160  
161 < 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
161 > 4. Update test suite to include a test for a stored proc returning a text blob.
162  
163 < 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
164 <   that BindFields is called when the query is next activated. Avoids FieldName
165 <   not found error.
163 > 5. IAttachment: add
164 >      function GetRemoteProtocol: AnsiString;
165 >      function GetODSMajorVersion: integer;
166 >      function GetODSMinorVersion: integer;
167 >      function GetAuthenticationMethod: AnsiString;
168  
169 < 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
170 <   purpose and allows the programmer to define any action they want for Update, Insert
182 <   or Delete. This may be complex SQL (similar to a Trigger), application specific
183 <   filtering of updates, or use of statements such as Grant or Revoke instead of
184 <   normal DML. See User Manual for more information.
169 >   These results are cached when the connection is opened and hence do not
170 >   require a database lookup.
171  
172 < IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
172 > 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
173 >   connect string used to create/connect to the database.
174  
175 < 1. TIBEvents: Fix uninitialised variable that could result in lost events.
175 > 7. IAttachment: Create Database using SQL statement. The username and password
176 >   are now extracted and used to populate a DPB made available via IAttachment.getDPB.
177 >   It is now possible to use IAttachment disconnect/connect to reconnect to
178 >   a database for which the initial connection was established by a create
179 >   database sql statement. Available in FPC only.
180  
181 < 2. TIBExtract: Added support for FB3 "USAGE" privilege.
181 > 8. Update Test 1 to test 5, 6 and 7 above.
182  
183 < 3. TIBExtract: data formatted as Charset set "octets" is now output using
193 <   hexadecimal notation.
183 > 9. IBUtils code tidy up.
184  
185 < 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
186 <   using a simple XML format.
185 > 10. Parameter Block interfaces "find" method. As documented, this should have
186 >   returned a nil interface when the item could not be found. Instead, an empty
187 >   interface item was returned. "Find" now works as documented and will return
188 >   a nil interface if the item cannot be found.
189  
190 < 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
199 <   grants to these objects.
190 > 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
191  
192 < 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
193 <   dependency problems restoring complex databases.
192 > 12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
193 >    requests with additional parameters. This is to enable support for fb_info_page_contents
194 >    (return of page contents). Response to fb_info_page_contents returned as
195 >    a string with code page CP_NONE.
196  
197 < 7. TIBXScript: This component has been restructured to allow for the processing of
198 <   embedded XML in INSERT statements and to support interactive sources in addition
206 <   to non-interactive data sources such as files.
197 > 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
198 >    test suite updated.
199  
200 < 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
200 > 14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
201 >    a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
202  
203 < 9. TIBXScript: ISQL compatiable Set statements are now supported:
204 <   SET SQL DIALECT
205 <   SET TERM
213 <   SET AUTODDL
214 <   SET BAIL
215 <   SET ECHO
216 <   SET COUNT
217 <   SET STATS
218 <   SET NAMES <character set>
203 > 15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
204 >    An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
205 >    default connection port to be specified.
206  
207 < 10. IBVersion unit added to hold current IBX Version Number information.
207 > FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
208  
209 < 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
210 <    and domain definitions.
209 > 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
210 >   Scale is no longer ignored.
211  
212 < 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
213 <    fully supported.
212 > 2. Fix issues with setting SQL Param values using SetAsString with Date values
213 >   not in locale format but which are recognised by Firebird. Date values that
214 >   cannot be converted to a string using Pascal library are now passed through
215 >   to Firebird as Text Strings.
216  
217 < 13. TIBExtract: when a database dump includes data, the generator values are now also set.
217 > 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
218 >   UTF8 and not UNICODE_FSS.
219  
220 < 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
220 > 4. Charset ID problem. When using Firebird 3, with no default database character set
221 >   and a column has a non-default collation specified, an incorrect character set
222 >   id was being reported that could result in a 'division by zero' error when
223 >   used by IBX. This has now been fixed.
224  
225 < IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
225 > 5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
226 >   CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
227 >   the character sets supported can be updated on a per database basis. That is
228 >   it is possible to add a (Firebird) user defined character set to a database.
229  
230 < See also doc/IBX4LazarusGuide.pdf for important information on
231 < upgrading to IBX2.
230 > 6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
231 >   set supported by Firebird with the API.
232  
233 < 1. Size property of TIBStringField is now the width in characters of the field
234 <   and not the byte length. This applies only to multi-byte character sets such
239 <   as UTF8. The original approach aligned with TStringField. However, the TStringField
240 <   code is not recognised as a bug and hence this change to align the behaviour.
241 <   The TStringField change is expected in fpc 3.2.0.
233 > 7. Add missing isc_info_db_read_only to list of decoded Database Information items
234 >   in FBOutputBlock.pas and update test suite to include this item.
235  
236 < 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
244 <   true (default) then Size property value saved in the lfm is ignored. Size is
245 <   always set from the dynamic information read from the database. It is unclear
246 <   why anyone would want to override this and set Size to false.
236 > 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
237  
238 < 3. ibxscript: should now handle correctly a Case..End statement within a procedure
239 <   block.
238 > 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
239 >   library or finding it by disk location, the PATH environment variable is now also set to
240 >   include the FIREBIRD directory. This is to ensure that the correct dlls in the
241 >   firebird client library dependencies are loaded.
242  
243 < 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
252 <   exist when an attempt is made to connect to it (run time only) then an attempt
253 <   is made to create the database.
243 > 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
244  
245 < 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
256 <   has been successfully created as a result of a call to CreateDatabase or when
257 <   creating a database after it was found not to exist.
245 > 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
246  
247 < 6.  DBControlGrid: a race condition could result in the wrong row image being
260 <    written to the cache. This has been avoided by a trip round the message
261 <    loop before rendering the row image.
247 > 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
248  
249 < 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
250 <    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
251 <    known to risk corrupt rendering of row images when the control is first
252 <    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
267 <    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
249 > 13. FB30Statement: A check has been added to ensure that all SQL Parameters
250 >    have been given a value (including NULL). Previously, failing to set the
251 >    value of an SQL Parameter could give rise to unpredictable results or
252 >    an SQLDA error.
253  
254 < 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
270 <    a TDateEdit control located on an editor panel.
254 > 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
255  
256 < 9.  TIBExtract: brought up-to-date plus many bug fixes.
256 > 15. FBAttachment: Avoid string reference count error when processing an Ansistring
257 >    parameter in an array of const passed to IAttachment.OpenCursor, etc.
258  
259 < 10. DBControlGrid: Removed memory leak when updating rows.
259 > 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
260 >    of const passed to IAttachment.OpenCursor, etc.
261  
276 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.

264  
265 < 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
281 <   when target codepage is CP_NONE. This is a workaround for
282 <   http://bugs.freepascal.org/view.php?id=30622.
265 > 1. Change syntax to Mode Delphi
266  
267 < 2. DBLog option removed from TIBStatisticalService - not supported by server
268 <   since Firebird 1.5.
267 > 2. Change all uses of string type to explicit AnsiString in order to ensure
268 >   compatibility between Delphi and FPC.
269  
270 < 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
271 <   similar.
270 > 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
271 >   defined for each interface.
272  
273 < 4. IBCodePage: updated mapping between codepages and character id.
273 > 4. Generics syntax variations for Delphi added
274  
275 < 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
276 <   Firebird. Character sets with a char width of two are not UTF16.
275 > 5. PChar replaced with PByte expect where an actual string is being referenced,
276 >   where PAnsiChar is used instead.
277  
278 < 6. Strings received from the database are now always transliterated into UTF8
296 <   regardless of the database character set or connection character set. This
297 <   is for compatibility with the LCL.
278 > 6. Review of type definitions in IBExternals to ensure Delphi compatibility
279  
280 < IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
280 > 7. Testsuite updated for Delphi
281  
282 < 1. IBBlob: Defer reading of blob until read method called. This avoids having to
302 <   read in an entire blob just to get the size of the blob. General performance
303 <   improvement when opening datasets containing blobs.
282 > FBINTF Change Log  version            (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
283  
284 < 2. Clearing a  Blob now sets the corresponding field's modified flag.
284 > 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
285 >   large blobs and the FB3 API.
286  
287 < 3. IBLookupCombo: When not performing auto-complete, original query sort order
288 <   is now used.
287 > 2. Update Event Handling algorithm to avoid looping due to recreation of the
288 >   event block.
289  
290 < 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
311 <   determined.
290 > 3. Avoid invalid XSQLDA error when the only parameter is updated to null
291  
292 < 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
292 > 4. Array Handling: fix problem with text arrays with character set none. When the
293 >   DB connection has a default character set (e.g. UTF8), an error is raised by
294 >   Firebird if the space allocated is not enough to allow for transliteration, even
295 >   though it is not required for character set none.
296  
297 < 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
316 <   lazarus 1.6.0
297 > 5. IBUtils: List of reserved words brought up-to-date
298  
299 < 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
319 <   compilation error.
299 > 6. Add ISQL style performance statistics collection to IStatement
300  
301 < IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
301 > 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
302 >   CREATE DATABASE statement.
303  
304 < 1. No character set specified for connection: when a text blob is retrieved, the
305 <  character set is determined by looking up the native character set using then
325 <  Firebird API. Otherwise a text mode blob is assumed to have the same character
326 <  set as the connection.
304 > 8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in
305 >   an array dimension is not mistaken for a named parameter prefix.
306  
307 < 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
308 <   for Login Dialog returing a change to the database path.
307 > 9. Trim function no longer applied to result of GetAsString for SQL_TEXT
308 >   when Character set is octets. Avoids loss of non printable characters at start of string.
309  
310 < 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
311 <   to be changed from that given in the TIBDatabase/TIBServer component and for the
312 <   entered value to be saved on a project specific basis (design time only).
310 > 10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
311 >    statistics for the last action. Requires use of procedure IStatement.EnableStatistics
312 >    to enable stats gathering.
313  
314 < 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
336 <   column fieldname. If they are the same then it is acts as a look up for the KeyValue
337 <   Otherwise, it sets the column text to the selected ListField Value.
314 > 11. API Version information added as constants to IB.pas
315  
316 < 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
340 <   column width.
316 > 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
317  
318 < 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
343 <   and a case insensitive search is requested.
318 > 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
319  
320 < 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
346 <   or column ListSource.

321  
322 < 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
349 <   unprepare) when closing and the text has not changed.
322 > 1. Initial Release
323  
351 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
352   Less likely to cause a cursor re-use error on Windows.
353
354 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
355   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
356
357 11. TIBTreeView: Guard against nil destination on record changed
358
359 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
360    string type with the code page set to reflect the returned field encoding after
361    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
362    earlier versions.
363
364 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
365    will now result in transliteration to the code page specified for the Firebird driver
366    if the assigned string has a different code page. FPC 3.0.0 onwards only.
367
368 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
369    is ignored and the lc_ctype value, when the database is opened, is set to align with
370    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
371    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
372    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
373    the GETACP is used to determine the Windows code page.
374
375 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
376    name used as the lc_ctype when the database was opened. Only valid while the
377    Database is connected.
378
379 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
380    id that corresponds to the DefaultCharSetName.
381
382 IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
383
384 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
385   path is given and database attach fails due to access permission issues on the
386   temp directory or security database, then the attach is retried with "localhost:"
387   prefixing the databasename. This should avoid problems when the database has to
388   be accessed by a local (e.g. classic) server and libfbembed is used.
389
390 2. Windows: revised search order for Firebird DLL:
391     i.   The Firebird Embedded Server in the application Directory.
392     ii.  If the FIREBIRD environment variable is set then the directory this
393          points to is searched for the FB Client DLL and then then underlying
394          "bin" directory.
395     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
396          is used to locate the Firebird installation directory and the underlying
397          "bin" directory is searched for the FB Client DLL.
398     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
399          are searched for the FB Client DLL.
400     v.   The PATH Environment variable is used to search for the FB Client DLL.
401     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
402
403 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
404   See doc/readme.scriptengine and example applications.
405
406 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
407   simplify the use of the embedded firebird server on both Linux and Windows platforms.
408   See dpc/readme.localdatabase and example applications.
409
410 5. IBDynamicGrid: Reordering on column header click should now also work for
411   dynamic columns.
412
413 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
414   between incrementing/decrementing the lock count and signalling the event.
415
416 IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
417
418 1.3.2 was never formally released and only made available as beta copies.
419
420 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
421
422 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
423
424 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
425
426 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
427   i.e. when it is a calculated field
428
429 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
430   This problem was due to a race condition between recalculating row heights and
431   determining which row was selected by the mouse click. The row height calculation
432   is now deferred by an extra trip round the message loop allowing the row to
433   be always calculated on the current grid layout rather than risking it being
434   calculated on the grid layout after the expanded row has been shrunk.
435
436 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
437   Windows.
438
439 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
440   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
441   to be determined at runtime. See doc/readme.charactersets.html.
442
443 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
444   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
445
446 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
447   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
448   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
449
450   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
451   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
452   implies no truncation.
453
454 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
455
456 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
457   (avoids "Not in Edit Mode" error).
458
459 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
460
461 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
462    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
463
464 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
465
466 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
467
468 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
469
470 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
471
472 IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
473
474 1.   OnCloseUp Event Handler added to TDBLookupProperties
475
476 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
477     problem with row size when exception is called.
478
479 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
480
481 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
482     in a TCustomComboBox and ignores return key if in a TCustomMemo
483
484 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
485     keyed in i.e. when autocomplete not performed
486
487 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
488     console mode applications with all LCL required functions (builtin dialogs and
489     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
490     not included in your project, IBX should compile and link with a console mode program.
491     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
492     console mode application or the IDE will automatically assume that your
493     application is GUI based. Instead, you should include the ibexpressconsolemode package.
494
495     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
496     to use the built in dialogs and cursor management. IBDialogs is
497     included by default if "ibexpress" is in your project source's "uses" clause.
498     This should be the case for all projects created through the IDE. This is why
499     you do not want to add the ibexpress package to console mode applications. The
500     ibexpressconsolemode package has been created to allow console mode programs
501     to avoid adding LCL dependencies when using IBX, while still having the
502     unit search paths set up correctly.
503
504     Existing users should check to ensure that the "ibexpress" unit is included in
505     each project's source file (*.lpr).
506
507     You may find that in order for the IDE to recognise that ibexpressconsolemode
508     exists, you have to first open the package in the IDE and then close it. This
509     adds it to the most recently accessed packages list. To make it permanently
510     available, add the package name to lazarus' staticpackages.inc file.
511
512         Thanks to Julio Jiménez for suggesting support of console mode.
513
514 7.   SQL Parser can now accept quoted strings that include new lines
515
516 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
517     of text on start of edit. This is particularly useful when tabbing to a
518     column and then inserting text.
519
520 9.   New Examples provided for IB Services and ISQLMonitor.
521
522 10. Fix error when writing to blob streams that recorded only the last buffer
523    write in the blob stream. In most cases, this did not cause a problem as the
524    IB Blob Stream is written in a single write. However, with the TDBImage, write
525    of a graphic type prefix was lost which caused a problem when the image could
526        not be automatically recognised.
527
528 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
529    already open" errors due to random numbers used for the cursor name being identical.
530
531 12. IBTable: corrected error that could result in an "Index out of bounds" error
532    when opening the table and the Primary Key is the last or only column in the
533    table. Thanks to Rick Hoover for the fix.
534
535 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
536    of "UTF-8", and update list of available database character sets. Existing
537    users should check the current lc_ctype setting in their applications.
538
539 IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
540
541 1.  Firebird Services: avoid List Index error when opening a service with an
542    empty Params property.
543
544 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
545    Link now set up in Loaded method - avoids occasional failure to apply
546    SQL markup on initial open.
547
548 3.  "Employees" example performance improvements when scrolling.
549
550 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
551    TFrame. Force recaching of selected frame to avoid GTK race (results in a
552    random image cached).
553
554 5.  DBControlGrid: Should now react to changes in panel height at run time.
555
556 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
557    even when further rows exist.
558
559 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
560    always be derived from panel height and setting this property can cause confusion.
561    Note for existing projects: to avoid a missing property error at run time,
562    each form using the DBControlGrid must be opened, updated and saved in the IDE
563    in order to remove the property value from the lfm.
564
565
566 IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
567
568 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
569    call Prepare before setting parameter values.
570
571 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
572
573 3.  Code tidyup and more robust handling of dsql information result vector.
574
575 4.  Support for centralised handling of transaction status changes. TIBTransaction
576    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
577    and "AfterExecQuery". The first three are called after the same event is called
578    for an IBCustomDataSet descendent using the Transaction. The fourth is called
579    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
580    enable monitoring of transaction status changes for a given transaction to be
581    handled in a single place. For example, when a change to the dataset occurs
582    an indicator can be set that shows the user that in order to save changes,
583    the transaction should be committed.  Rather than doing this per dataset, this
584    can now be done per transaction.
585
586 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
587    the dataset is scrolled. However, any changes to the current row are, by default,
588    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
589    have a new property "DataSetCloseAction" that adds automatic posting of changes
590    on dataset close. If this property is set to dcDiscardChanges (default) then the
591    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
592    then IBX will attempt to post any unsaved changes before the dataset is closed
593    (and after the BeforeClose event handler is called). The exception is when the
594    dataset is being closed as a result of a transaction rollback. In this case,
595    no action is taken and any unsaved  changes are discarded. This avoids both
596    unnecessary overhead and the risk that a validation error may occur in the Post
597    raising an exception and thereby preventing a rollback.
598
599 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
600    In earlier versions, the Display Width was set to the maximum byte width rather than the character
601    width. Display Widths are now corrected by dividing by the max byte width per character.
602    For UTF8 character sets, the byte width is four and hence the Display Width will be
603    the byte width divided by 4. The byte width of each character set is determined
604    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
605    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
606
607 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
608
609 8.  IBLookupComboEditBox: List should now always be restored to full list when the
610    control loses focus. Default Key press default interval reduced to 200ms.
611
612 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
613    when dataset rows are less than visible rows.
614
615 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
616    does not exist or DataSet is empty. More responsive on dataset open. New event
617    OnRestorePosition. Column sort disabled if no header row.
618
619 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
620    while dataset state is dsInsert. Avoids posting errors.
621
622 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
623    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
624
625 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
626
627 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
628    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
629    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
630    always "posts" the current record regardless or whether or not it may be more appropriate
631    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
632    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
633    as the first action of the "Post" method and allows the handler to convert the Post
634    into a Cancel if that is the appropriate action on moving to a different row. This is
635    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
636    raised here, but it may still be more appropriate to validate a post and signal
637    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
638
639 15. On Unix derived systems, the Firebird library name can now be given as a colon
640    separated list. Each library name on the list is tried in turn, in left to right
641    order with the first found being used as the firebird library. By default, on Linux,
642    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
643    overidden by the FBLIB environment variable or the OnGetLibraryName function.
644
645    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
646    then it will still attempt to access the database via the Firebird Server and will
647    require a username and password. If only the pathname is given, then the username
648    and password should be omitted and the unix file permissions are used to grant
649    access.
650
651 IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
652
653 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
654    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
655    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
656    corresponds to a row of the linked DataSource. Any data aware control on the
657    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
658
659 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
660   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
661   takes place during database access. This may be useful when there are performance issues with
662   the change of cursor. Setting the property to false suppresses the change of cursor.
663
664 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
665   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
666   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
667   making all changes permanent immediately rather than when the transaction is explicitly
668   committed.
669
670 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
671   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
672
673 IBX Change Log  version      (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
674
675 Development version only.
676
677 IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
678
679 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
680   This is typically used during an "OnBeforeOpen" event handler to manipulate the
681   "Where" and "Having" clauses to implement user specified filters of arbitrary
682   complexity.
683
684 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
685   three new data aware controls dependent on IBX and which make use of the SQL Parser.
686   These are:
687
688   - TIBLookupComboEditBox
689   - TIBDynamicGrid
690   - TIBTreeview
691
692   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
693   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
694   to revise the available list and restrict it to items that are prefixed by the
695   typed text (either case sensitive or case insensitive). Autoinsert allows a
696   newly typed entry to be added to the list dataset and included in the available
697   list items.
698
699   TIBDynamicGrid is a TDBGrid descendent that provides for:
700   - automatic resizing of selected columns to fill the available row length
701   - automatic positioning and sizing of a "totals" control, typically at the
702     column footer, on a per column basis.
703   - DataSet resorting on header row click, sorting the dataset by the selected column.
704     A second click on the same header cell reversed the sort order.
705   - Support for a "Panel Editor". That is on clicking the indicator column, the row
706     is automatically expanded and a panel superimposed on it. The panel can have any
707     number of child controls, typically data aware controls with the same datasource
708     as the grid allowing for editing of additional fields and more complex editors.
709   - Reselection of the same row following resorting.
710   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
711     Its properties are specified on a per column basis and allows for one or more
712     columns to have their values selected from a list provided by a dataset.
713     Autocomplete and autoinsert are also available. The existing picklist editor
714     is unaffected by the extension.
715
716   TIBTreeView is a data aware TCustomTreeView.
717
718 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
719   zero scale will no longer return an error. An Int64 will be returned instead.
720
721 4. TIBTransaction now has events for Before and After Transaction End and a new function
722   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
723
724 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
725   repeated multiple times.
726
727 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
728   check used to get in the way of using Stored Procedures, and "Update or Insert"
729   statements.
730
731 7. Insert, Modify and Delete property Editors now support Query Generation from
732   Stored Procedures.
733
734 8. Three new examples illustrate the use of the new IB Controls
735
736
737 IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
738
739 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
740   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
741   Gabor Boros for reporting this problem and for testing the improvements).
742
743 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
744   See readme.field+param.names in the doc folder.
745
746 3. IBX SQL Editors will now automatically add double quotes around column names when the database
747   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
748
749 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
750
751 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
752   actions.
753
754 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
755   thanks to Yuriy Kopnin for pointing this out).
756
757 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
758
759 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
760   for both fields and parameter setting.
761
762 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
763   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
764
765 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
766    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
767
768 11. TIBTable now has a property editor for "MasterFields"
769
770 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
771    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
772
773 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
774    of settings is unrecognised. Selecting this radio button has no effect on the settings.
775

777 IBX Change Log  version                 (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
778
779 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
780
781 IBX Change Log  version          (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
782
783 1. In a TIBCustomDataset descendent, a generator now only sets the value when
784   it is null. This allows for alternative user defined setting of the generator
785
786   Many thanks to Julio Jiménez for this fix
787
788 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
789   and suggests that the user may have forgotten to install it.
790
791 IBX Change Log  version         (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
792
793 1. Conditional compilation used to limit registration of TIntegerField to
794   Lazarus versions less than 1.1
795
796 2. When a database connection is created, character set is now by default set
797   to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
798   1250 to 1254.
799
800
801 IBX Change Log  version     (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
802
803 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
804
805
806 IBX Change Log  version    (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
807
808 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
809   Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
810
811 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
812   package is changed to do this (which it should do).
813
814 IBX Change Log  version (1.0-0)  Sat, 28 Apr 2012 16:43:00 +0100
815
816 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
817
818 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
819
820 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
821
822 4. Property editors should now correctly resize.
823
824 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
825   (restored original functionality)
826
827 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
828   library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
