2 >
3 > 1. Add try-..except check when initially loading library in IDE. This should
4 > ensure that IDE continues to load even when a failure occurs in IBX load
5 > library.
6 >
7 > 2. IBXScript: now recognises a CASE...END block within a stored procedure and
8 >   hence will correctly detect end of the outer containing block when the block
9 >   contains a SELECT ... CASE ... END construct.
10 >
11 > 3. IBExtract: some further tidying up to remove extraneous white space.
12 >
13 > IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
14 >
15 > 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
16 >   exception of those defined to be one byte wide e.g. DBImplementationNo.
17 >
18 > 2. TIBSQL: Batch Update/Insert support added.
19 >
20 > 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
21 >   is no longer automatically converted to upper case when it is syntactically a
22 >   SQL Identifier. This is to support the use of stored procedures defined e.g.
23 >   as CREATE PROCEDURE "iCASE".
24 >
25 >   There could be a backwards compatibility issue when the StoredProcName was entered
26 >   manually at design time. That is not selected from the drop down list. If the
27 >   StoredProcName is entered in mixed case and the procedure was declared e.g. as
28 >   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
29 >   ensure that the value of the StoredProcName is all upper case, unless it was
30 >   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
31 >   quotes).
32 >
33 >   Note that when a stored procedure name was declared delimited in double quotes,
34 >   as in the first example above, the value of the StoredProcName property must not
35 >   include the delimiters (double quotes).
36 >
37 > 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
38 >   upgrade.conf was not found. This replaces silently ignoring the problem.
39 >
40 > 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
41 >   'Version.%.3d' and is used to generate the section header names (for a given
42 >   version no.) in the upgrade.conf file.
43 >
44 > IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
45 >
46 > 1. -c command line option added to fbsql example program. Used to set connection
47 >   character set.
48 >
49 > IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
50 >
51 > 1. Firebird 4 support added.
52 >
53 > 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
54 >   extended precision NUMERIC fields are supported.
55 >
56 > 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
57 >
58 > 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
59 >   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
60 >
61 > 5. IBExtract now supports FB4 enhancements:
62 >   - new data types as above
63 >   - Identity column extensions
64 >   - Default user role
65 >   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
66 >   - Internal Functions
67 >
68 > 6. IBExtract: new event: OnExtractLines.
69 >
70 > 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
71 >
72 > 8. IBXServices: Server version no. parsing now allows any letter before major version number
73 >   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
74 >
75 > 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
76 >   format for rendering a time zone.
77 >
78 > 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
79 >     to convert TIME WITH TIME ZONE data type values to and from GMT.
80 >
81 > 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
82 >    IIBGUIInterface and IIBTimerInf respectively.
83 >
84 > 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
85 >    now accessible as properties of TIBDatabase and TIBTransaction respectively.
86 >
87 > 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
88 >    truncated to its fixed character width rather than being right padded with
89 >    white space to the maximum data size.
90 >
91 > 14. TIBTable.Empty table. In additional to deleting all records in the underlying
92 >    table, the internal buffers are now also flushed ensuring that the TIBTable is
93 >    also empty.
94 >
95 > 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
96 >
97 > 16. TIBXControlService descendents: DatabaseName may now be set using a database
98 >    connect string. The database name is extracted from the connect string.
99 >
100 > 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
101 >
102 > 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
103 >
104 > 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
105 >    not being present as required.
106 >
107 > 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
108 >    version that can be customised to work with other database drivers.
109 >
110 > 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
111 >    unnecessary CR at end of line on Unix platforms.
112 >
113 > 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
114 >    seconds in order to reduce risk of message loss.
115 >
116 > 23. ISQLMonitor: read and write count statistics now available via:
117 >      property TIBSQLMonitor.ReadCount;
118 >      IIBSQLMonitorHook.GetWriteCount: integer;
119 >
120 > 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
121 >
122 > IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
123 >
124 > 1.  TIBStringField: when a string value is read from a dataset buffer, if the
125 >    number of UTF8 characters exceeds the string size then string is truncated
126 >    to the maximum string size. This is  usually a problem with fixed width columns
127 >    right padded with white space.
128 >
129 > 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
130 >    If SQLFiltered is set then when a dataset is opened, each line in the
131 >    SQLFilterParams property is assumed to be a SQL condition clause and
132 >    ANDed into the Where clause of the SQL Select statement provided as a
133 >    dataset property. Each such SQL condition thus acts as an additional filter
134 >    on the dataset.
135 >
136 > 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
137 >    side filters).
138 >
139 > 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
140 >   text matches complete entry.
141 >
142 > 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
143 >   dataset are active (avoids risk of access violation if master is inactive)
144 >
145 > 6. TIBEvents: Registered property can now be set at design time even if database not open
146 >
147 > 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
148 >   This should prevent "spillover" of events between sessions.
149 >
150 > 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
151 >   This should ensure that the internal buffer is set up correctly and avoids
152 >   a duplicate initial row.
153 >
154 > 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
155 >   That is, the DataSize should be the field size * character set width. The
156 >   value returned by DataSize is now the same as the Dataset buffer size reserved
157 >   for the field.
158 >
159 > 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
160 >
161 > 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
162 >    and vice-versa. This may result in an exception being raised (correctly) for
163 >    older programs when using dataset fields added to a form and the database has been
164 >    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
165 >    In such cases, the field needs to be deleted in the IDE fields editor and then
166 >    added back in.
167 >
168 > 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
169 >    false if query contains only white space and not just empty.
170 >
171 > 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
172 >    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
173 >    is cancelled.
174 >
175 > 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
176 >    called on a null field.
177 >
178 > 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
179 >    results in an empty dataTC86                Client side Filtered Dataset    1       X
180 > set.
181 >
182 > 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
183 >    a cached update is applied and an exception is raised.
184 >
185 > 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
186 >
187 > 17. Console Mode Local Database support: backup/restore should now work correctly.
188 >
189 > 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
190 >    possible and an exception raised.
191 >
192 > 19. MinimumVersionNo added to Local Database Support. Database will not open if
193 >    below this version no. and upgrade not possible.
194 >
195 > IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
196 >
197 > 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
198 >    not SQL Identifiers are now supported.
199 >
200 > 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
201 >    passed to the Firebird engine for execution.
202 >
203 > 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
204 >    is made to scroll back.
205 >
206 > 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
207 >
208 > 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
209 >   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
210 >
211 > 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
212 >   validated. If no match is found in the list of field names and the database has
213 >   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
214 >   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
215 >
216 > 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
217 >   with fpc 3.2.
218 >
219 > IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
220 >
221 >
222 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
223 >   and is used to override the default settings in the client side "firebird.conf" This
224 >   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
225 >   Each line of the string list should be a setting in the same format as "firebird.conf".
226 >   For example "WireCompression = true" in order to request wire compression on the client side.
227 >
228 >   Note: explicit settings in the client side "firebird.conf" appear to take precedence
229 >   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
230 >   also require a compatible setting in the server side "firebird.conf". For example
231 >   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
232 >   compression to be used.
233 >
234 >   Whether or not WireCompression or WireCrypt are in use can be checked using the information
235 >   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
236 >   ibx/examples/dbinfo for examples of how to display this information.
237 >
238 > 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
239 >   is a "convenience" property. If set the "WireCompression=true" is added to the
240 >   ConfigOverrides. If unchecked then this setting is removed.
241 >
242 > 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
243 >   not "INT64".
244 >
245 > 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
246 >   These are:
247 >    property TimestampFormat: string;
248 >    property DateFormat: string;
249 >    property TimeFormat: string;
250 >
251 >   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
252 >   DATETIME and TIME. The format strings use the standard FPC date/time format
253 >   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
254 >
255 >   If any of the above properties are set to an empty string, then the locale default
256 >   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
257 >   locale default is extended by appending '.zzz' to include milliseconds.
258 >
259 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
260 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
261 >
262 > 5. New published property for TIBCSVDataOut:
263 >     property QuoteStrings: boolean (default true)
264 >
265 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
266 >   used to delimit each and every string in the output.
267 >
268 > 6. New published properties for TIBCSVDataOut:
269 >    property FieldSeparator: string;
270 >    property HeaderSeparator: string;
271 >
272 >   Respectively, these provide the separator character(s) used to separate fields
273 >   in data and header rows. Both default to ','.
274 >
275 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
276 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
277 >    property OnFormatTextString;
278 >
279 >   This event handler can be used to process text strings before they are included
280 >   in the output e.g. to replace unprintable characters with alternative strings.
281 >   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
282 >
283 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
284 >   Uses "FindParam" if in order to find out if a parameter with a given name exists
285 >   and without raising and exception if it does not.
286 >
287 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
288 >   consistency with SQL queries.
289 >
290 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
291 >    When true, SQL statement parameter names are parsed case sensitive. Note for
292 >    TIBDataSet only applies to Select query.
293 >
294 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
295 >    an IDE exception.
296 >
297 > 12. LocalDBSupport: initial database creation should now work correctly
298 >    when the schema source is an sql file.
299 >
300 > 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
301 >    when defined, this handler will be called by the internal TIBXScript during
302 >    initial database creation when the schema source is an sql file and may be used
303 >    to provide a visual indication of progress in console mode.
304 >
305 > 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
306 >    to true while a new local database is being created and its schema populated.
307 >    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
308 >    when the database is disconnected/connected during the create DB procedure.
309 >
310 > 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
311 >    are now always ignored and replaced by the user name and password provided as
312 >    the login parameters for the TIBDatabase referenced from the TIBXScript. The
313 >    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
314 >    completely ignored if this property is true.
315 >
316 > 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
317 >    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
318 >    ImageIndex and SelectImageIndex values on AddNode.
319 >
320 > 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
321 >    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
322 >    the same database connection.
323 >
324 > 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
325 >    if provided, this should be an conditional SQL expression suitable for
326 >    including in an SQL Select statement "where" clause. If non-empty and the
327 >    "Filtered" property is true then the SQL expression provided as the value of
328 >    the "Filter" property is "ANDed" with any existing condition statement
329 >    in the SQL statement's "Where" clause.
330 >
331 >    If the "Filter" property is set at run time, the "Filtered" property is true
332 >    and the dataset is already open, then the dataset is closed and re-opened automatically.
333 >
334 >    The "Filter" condition may include IBX style parameters. In which case, their
335 >    value must be set by the dataset's "OnBeforeOpen" event handler.
336 >
337 >    This is a public property for TIBDataSet and TIBQuery query and intended for
338 >    use at run time.
339 >
340 >    Note: The property is a published property of TIBTable. The TIBTable functionality
341 >    is unaffected by this change.
342 >
343 > IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
344 >
345 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
346 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
347 >   mode apps.
348 >
349 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
350 >   statement. This avoids problems if "Execute Block" is used as the Query.
351 >
352 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
353 >   internal SQL tokeniser routines.
354 >
355 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
356 >   as a select statement, with or without CTEs.
357 >
358 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
359 >
360 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
361 >   internal SQL tokeniser routines.
362 >
363 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
364 >    being raised for valid set statements processed by a data formatter.
365 >
366 > 8. New published property for TIBDatabase and TIBXServicesConnection. This is
367 >   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
368 >   the path of the Firebird Library used by the database/services connection.
369 >
370 > 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
371 >   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
372 >   services connection.
373 >
374 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
375 >   or param name is not a valid SQL identifier.
376 >
377 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
378 >    view of whether the text box should be editable when no DataSource is specified.
379 >    TIBLookupComboEditBox has been updated to workaround this problem. As long as
380 >    ReadOnly is false, the text box is editable when no DataSource is specified.
381 >
382 > 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
383 >    the FBLIB environment variable. If you do not want to permit this then you
384 >    must modify the Register procedure in the design/IBDBReg.pas unit to remove
385 >    this setting.
