2 >
3 > 1.  TIBStringField: when a string value is read from a dataset buffer, if the
4 >    number of UTF8 characters exceeds the string size then string is truncated
5 >    to the maximum string size. This is  usually a problem with fixed width columns
6 >    right padded with white space.
7 >
8 > 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
9 >    If SQLFiltered is set then when a dataset is opened, each line in the
10 >    SQLFilterParams property is assumed to be a SQL condition clause and
11 >    ANDed into the Where clause of the SQL Select statement provided as a
12 >    dataset property. Each such SQL condition thus acts as an additional filter
13 >    on the dataset. (Not yet tested)
14 >
15 > 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
16 >    side filters).
17 >
18 > 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
19 >   text matches complete entry.
20 >
21 > 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
22 >   dataset are active (avoids risk of access violation if master is inactive)
23 >
24 > 6. TIBEvents: Registered property can now be set at design time even if database not open
25 >
26 > 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
27 >   This should prevent "spillover" of events between sessions.
28 >
29 > 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
30 >   This should ensure that the internal buffer is set up correctly and avoids
31 >   a duplicate initial row.
32 >
33 > 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
34 >   That is, the DataSize should be the field size * character set width. The
35 >   value returned by DataSize is now the same as the Dataset buffer size reserved
36 >   for the field.
37 >
38 > 10. IBExtact: Tidyup of SQL generation. Avoid unnecessary double quotes.
39 >
40 > 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
41 >    and vice-versa. This may result in an exception being raised (correctly) for
42 >    older programs when using dataset fields added to a form and the database has been
43 >    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
44 >    In such cases, the field needs to be deleted in the IDE fields editor and then
45 >    added back in.
46 >
47 > 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
48 >    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
49 >    is cancelled.
50 >
51 > IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
52 >
53 > 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
54 >    not SQL Identifiers are now supported.
55 >
56 > 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
57 >    passed to the Firebird engine for execution.
58 >
59 > 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
60 >    is made to scroll back.
61 >
62 > 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
63 >
64 > 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
65 >   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
66 >
67 > 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
68 >   validated. If no match is found in the list of field names and the database has
69 >   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
70 >   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
71 >
72 > 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
73 >   with fpc 3.2.
74 >
75 > IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
76 >
77 >
78 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
79 >   and is used to override the default settings in the client side "firebird.conf" This
80 >   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
81 >   Each line of the string list should be a setting in the same format as "firebird.conf".
82 >   For example "WireCompression = true" in order to request wire compression on the client side.
83 >
84 >   Note: explicit settings in the client side "firebird.conf" appear to take precedence
85 >   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
86 >   also require a compatible setting in the server side "firebird.conf". For example
87 >   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
88 >   compression to be used.
89 >
90 >   Whether or not WireCompression or WireCrypt are in use can be checked using the information
91 >   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
92 >   ibx/examples/dbinfo for examples of how to display this information.
93 >
94 > 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
95 >   is a "convenience" property. If set the "WireCompression=true" is added to the
96 >   ConfigOverrides. If unchecked then this setting is removed.
97 >
98 > 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
99 >   not "INT64".
100 >
101 > 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
102 >   These are:
103 >    property TimestampFormat: string;
104 >    property DateFormat: string;
105 >    property TimeFormat: string;
106 >
107 >   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
108 >   DATETIME and TIME. The format strings use the standard FPC date/time format
109 >   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
110 >
111 >   If any of the above properties are set to an empty string, then the locale default
112 >   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
113 >   locale default is extended by appending '.zzz' to include milliseconds.
114 >
115 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
116 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
117 >
118 > 5. New published property for TIBCSVDataOut:
119 >     property QuoteStrings: boolean (default true)
120 >
121 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
122 >   used to delimit each and every string in the output.
123 >
124 > 6. New published properties for TIBCSVDataOut:
125 >    property FieldSeparator: string;
126 >    property HeaderSeparator: string;
127 >
128 >   Respectively, these provide the separator character(s) used to separate fields
129 >   in data and header rows. Both default to ','.
130 >
131 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
132 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
133 >    property OnFormatTextString;
134 >
135 >   This event handler can be used to process text strings before they are included
136 >   in the output e.g. to replace unprintable characters with alternative strings.
137 >   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
138 >
139 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
140 >   Uses "FindParam" if in order to find out if a parameter with a given name exists
141 >   and without raising and exception if it does not.
142 >
143 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
144 >   consistency with SQL queries.
145 >
146 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
147 >    When true, SQL statement parameter names are parsed case sensitive. Note for
148 >    TIBDataSet only applies to Select query.
149 >
150 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
151 >    an IDE exception.
152 >
153 > 12. LocalDBSupport: initial database creation should now work correctly
154 >    when the schema source is an sql file.
155 >
156 > 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
157 >    when defined, this handler will be called by the internal TIBXScript during
158 >    initial database creation when the schema source is an sql file and may be used
159 >    to provide a visual indication of progress in console mode.
160 >
161 > 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
162 >    to true while a new local database is being created and its schema populated.
163 >    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
164 >    when the database is disconnected/connected during the create DB procedure.
165 >
166 > 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
167 >    are now always ignored and replaced by the user name and password provided as
168 >    the login parameters for the TIBDatabase referenced from the TIBXScript. The
169 >    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
170 >    completely ignored if this property is true.
171 >
172 > 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
173 >    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
174 >    ImageIndex and SelectImageIndex values on AddNode.
175 >
176 > 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
177 >    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
178 >    the same database connection.
179 >
180 > 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
181 >    if provided, this should be an conditional SQL expression suitable for
182 >    including in an SQL Select statement "where" clause. If non-empty and the
183 >    "Filtered" property is true then the SQL expression provided as the value of
184 >    the "Filter" property is "ANDed" with any existing condition statement
185 >    in the SQL statement's "Where" clause.
186 >
187 >    If the "Filter" property is set at run time, the "Filtered" property is true
188 >    and the dataset is already open, then the dataset is closed and re-opened automatically.
189 >
190 >    The "Filter" condition may include IBX style parameters. In which case, their
191 >    value must be set by the dataset's "OnBeforeOpen" event handler.
192 >
193 >    This is a public property for TIBDataSet and TIBQuery query and intended for
194 >    use at run time.
195 >
196 >    Note: The property is a published property of TIBTable. The TIBTable functionality
197 >    is unaffected by this change.
198 >
199 > IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
200 >
201 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
202 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
203 >   mode apps.
204 >
205 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
206 >   statement. This avoids problems if "Execute Block" is used as the Query.
207 >
208 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
209 >   internal SQL tokeniser routines.
210 >
211 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
212 >   as a select statement, with or without CTEs.
213 >
214 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
215 >
216 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
217 >   internal SQL tokeniser routines.
218 >
219 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
220 >    being raised for valid set statements processed by a data formatter.
221 >
222 > 8. New published property for TIBDatabase and TIBXServicesConnection. This is
223 >   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
224 >   the path of the Firebird Library used by the database/services connection.
225 >
226 > 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
227 >   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
228 >   services connection.
229 >
230 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
231 >   or param name is not a valid SQL identifier.
232 >
233 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
234 >    view of whether the text box should be editable when no DataSource is specified.
235 >    TIBLookupComboEditBox has been updated to workaround this problem. As long as
236 >    ReadOnly is false, the text box is editable when no DataSource is specified.
237 >
238 > 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
239 >    the FBLIB environment variable. If you do not want to permit this then you
240 >    must modify the Register procedure in the design/IBDBReg.pas unit to remove
241 >    this setting.
242 >
243 > IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
244 >
245 > 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
246 >   Utf8EscapeControlChars
247 >
248 > IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
249 >
250 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
251 > all previous copies of the IBX source code tree before installing this release.
252 >
253 > The IBX packages used by most users have not changed, with one exception. The
254 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
255 > to use the IBServices unit in your applications, please add the iblegacyServices
256 > to the list of dependencies. To do this, open the Project Inspector and select
257 > Add->New Requirement and select "ibLegacyServices" from the list of available
258 > packages.
259 >
260 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
261 >   the IBServices unit providing what is intended to be a clearer and easier to
262 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
263 >   more information and the guide to "Firebird Service Management Using IBX".
264 >   As indicated above, the legacy services components are still available and
265 >   provided in a separate package. There is no need to update working applications
266 >   using the older versions except for an additional package dependency.
267 >
268 > 2. The IBX packages and source code tree have been re-organised in an attempt to
269 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
270 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
271 >   new set of IBX packages.
272 >
273 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
274 >   updated to use the new Services API components.
275 >
276 > 4. The iblocal package has been updated to use the new Services API components.
277 >
278 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
279 >   TIBXSecurityService. It had been wrongly classified in the previous version
280 >   as a per database configuration item. It is global to a server and hence
281 >   correctly positioned as part of the Security Package. In the DBAdmin example,
282 >   the setting has moved to the mappings page.
283 >
284 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
285 >   are ignored.
286 >
287 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
288 >   closed before the database is dropped. Before and After Disconnect event handlers
289 >   are also fired.
290 >
291 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
292 >   is started and not just the first time.
293 >
294 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
295 >   depenendency with comp type.
296 >
297 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
298 >
299 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
300 >    then this is recognised and not ignored.
301 >
302 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
303 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
304 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
305 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
306 >
307 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
308 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
309 >    counters for the select query. Note: stats accumulate after each fetch from
310 >    the database. To get total query cost after open, call the "Last" method
311 >    and then GetPerfStatistics.
312 >
313 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
314 >
315 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
316 >    in parenthesises.
317 >
318 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
319 >    SQL identifiers are always delimited by double quotes. If false, then they are
320 >    only delimited if the identifier is a reserved word, contains lower case or special
321 >    characters. Set this property to true to retain previous behaviour.
322 >
323 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
324 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
325 >
326 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
327 >       property MasterDetailDelay: integer {defaults to zero}
328 >
329 >    When non-zero and the dataset is a detail table referencing a master table
330 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
331 >    then a synchronisation delay is added (in milliseconds) between the master
332 >    row changing and the detail dataset being re-opened. If the master dataset
333 >    is scrolled before the delay expires then the delay is reset. This can be used
334 >    to avoid performance overheads when scrolling through a large master dataset.
335 >
336 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
337 >    chreads unit must be included in your project. TTimer is not used in order
338 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
339 >
340 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
341 >    with Extract Option eoDatabase.
342 >
343 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
344 >    When a deLayoutChanged event is reported on the ListSource dataset, the
345 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
346 >    relationship with the control's datasource (master).
347 >
348 > 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
349 >
350 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
351 >    stubs. Pedantic fix really, as procedures output in dependency order anyway.
352 >
353 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
354 >    DDL (Firebird 3 and later only).
355 >
356 > 22. TIBLookupComboBox Autocomplete Fixes:
357 >    i. Only appended text is now selected after autocomplete.
358 >    ii. Uppercase keys no longer ignored for autocomplete.
359 >    iii. Retain Prefix case is now honoured correctly.
360 >    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
361 >        before autocomplete performed. i.e. behaviour now the same as when
362 >        no DataSource assigned.
363 >
364 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
365 >    between SQL statements.
366 >
367 > 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
368 >    ObjectNames are converted to upper case before matching against metadata object
369 >    names, unless the objectname is delimited by double quotes, in which case, the
370 >    double quotes are removed and the remaining string is used (unmodified) to match
371 >    against the metadata object name.
372 >
373 >    If true then the ObjectName is used as is without modification and matched
374 >    against the metadata object name. No attempt is made to remove double quotes.
375 >
376 > 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
377 >    with eoTrigger, these extract types can be used to select only Database Triggers,
378 >    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
379 >
380 > 26. TIBXScript: If an exception occurs during the processing of a statement, the
381 >    statement separate character is now reset to the default (';').
382 >
383 > 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
384 >
385 > 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
386 >    a commit or reconnect statement and instead activated only when next SQL statement
387 >    is executed.
388 >
389 > 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
390 >
391 > 30. TIBXScript: case insensitive regex now used when matching statements instead of
392 >    converting statement to upper case.
393 >
394 > 31. TIBExtract: metadata comments now supported. New published property
395 >    IncludeMetaDataComments (default true). If true then metadata comments included
396 >    in extracted DDL. New Extract Object member eoComments. This may be used with
397 >    ExtractObject method to list all metadata comments.
398 >
399 > 32. TIBExtract: ListObjectNames method added.
400 >
401 > 33. Updated Database component editor to support additional connection string
402 >    types.
