1 + IBX Change Log  version (2.4-0 Build 12473) Wed, 17 Feb 2021 10:49:57 +0000
2 +
3 + 1. Firebird 4 support added.
4 +
5 + 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
6 +   extended precision NUMERIC fields are supported.
7 +
8 + 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
9 +
10 + 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
11 +   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
12 +
13 + 5. IBExtract now supports FB4 enhancements:
14 +   - new data types as above
15 +   - Identity column extensions
16 +   - Default user role
17 +   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
18 +   - Internal Functions
19 +
20 + 6. IBExtract: new event: OnExtractLines.
21 +
22 + 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
23 +
24 + 8. IBXServices: Server version no. parsing now allows any letter before major version number
25 +   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
26 +
27 + 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
28 +   format for rendering a time zone.
29 +
30 + 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
31 +     to convert TIME WITH TIME ZONE data type values to and from GMT.
32 +
33 + 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
34 +    IIBGUIInterface and IIBTimerInf respectively.
35 +
36 + 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
37 +    now accessible as properties of TIBDatabase and TIBTransaction respectively.
38 +
39 + 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
40 +    truncated to its fixed character width rather than being right padded with
41 +    white space to the maximum data size.
42 +
43 + 14. TIBTable.Empty table. In additional to deleting all records in the underlying
44 +    table, the internal buffers are now also flushed ensuring that the TIBTable is
45 +    also empty.
46 +
47 + 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
48 +
49 + 16. TIBXControlService descendents: DatabaseName may now be set using a database
50 +    connect string. The database name is extracted from the connect string.
51 +
52 + 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
53 +
54 + 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
55 +
56 + 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
57 +    not being present as required.
58 +
59 + 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
60 +    version that can be customised to work with other database drivers.
61 +
62 + IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
63 +
64 + 1.  TIBStringField: when a string value is read from a dataset buffer, if the
65 +    number of UTF8 characters exceeds the string size then string is truncated
66 +    to the maximum string size. This is  usually a problem with fixed width columns
67 +    right padded with white space.
68 +
69 + 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
70 +    If SQLFiltered is set then when a dataset is opened, each line in the
71 +    SQLFilterParams property is assumed to be a SQL condition clause and
72 +    ANDed into the Where clause of the SQL Select statement provided as a
73 +    dataset property. Each such SQL condition thus acts as an additional filter
74 +    on the dataset.
75 +
76 + 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
77 +    side filters).
78 +
79 + 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
80 +   text matches complete entry.
81 +
82 + 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
83 +   dataset are active (avoids risk of access violation if master is inactive)
84 +
85 + 6. TIBEvents: Registered property can now be set at design time even if database not open
86 +
87 + 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
88 +   This should prevent "spillover" of events between sessions.
89 +
90 + 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
91 +   This should ensure that the internal buffer is set up correctly and avoids
92 +   a duplicate initial row.
93 +
94 + 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
95 +   That is, the DataSize should be the field size * character set width. The
96 +   value returned by DataSize is now the same as the Dataset buffer size reserved
97 +   for the field.
98 +
99 + 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
100 +
101 + 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
102 +    and vice-versa. This may result in an exception being raised (correctly) for
103 +    older programs when using dataset fields added to a form and the database has been
104 +    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
105 +    In such cases, the field needs to be deleted in the IDE fields editor and then
106 +    added back in.
107 +
108 + 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
109 +    false if query contains only white space and not just empty.
110 +
111 + 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
112 +    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
113 +    is cancelled.
114 +
115 + 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
116 +    called on a null field.
117 +
118 + 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
119 +    results in an empty dataTC86                Client side Filtered Dataset    1       X
120 + set.
121 +
122 + 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
123 +    a cached update is applied and an exception is raised.
124 +
125 + 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
126 +
127 + 17. Console Mode Local Database support: backup/restore should now work correctly.
128 +
129 + 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
130 +    possible and an exception raised.
131 +
132 + 19. MinimumVersionNo added to Local Database Support. Database will not open if
133 +    below this version no. and upgrade not possible.
134 +
135 + IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
136 +
137 + 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
138 +    not SQL Identifiers are now supported.
139 +
140 + 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
141 +    passed to the Firebird engine for execution.
142 +
143 + 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
144 +    is made to scroll back.
145 +
146 + 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
147 +
148 + 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
149 +   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
150 +
151 + 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
152 +   validated. If no match is found in the list of field names and the database has
153 +   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
154 +   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
155 +
156 + 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
157 +   with fpc 3.2.
158 +
159 + IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
160 +
161 +
162 + 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
163 +   and is used to override the default settings in the client side "firebird.conf" This
164 +   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
165 +   Each line of the string list should be a setting in the same format as "firebird.conf".
166 +   For example "WireCompression = true" in order to request wire compression on the client side.
167 +
168 +   Note: explicit settings in the client side "firebird.conf" appear to take precedence
169 +   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
170 +   also require a compatible setting in the server side "firebird.conf". For example
171 +   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
172 +   compression to be used.
173 +
174 +   Whether or not WireCompression or WireCrypt are in use can be checked using the information
175 +   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
176 +   ibx/examples/dbinfo for examples of how to display this information.
177 +
178 + 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
179 +   is a "convenience" property. If set the "WireCompression=true" is added to the
180 +   ConfigOverrides. If unchecked then this setting is removed.
181 +
182 + 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
183 +   not "INT64".
184 +
185 + 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
186 +   These are:
187 +    property TimestampFormat: string;
188 +    property DateFormat: string;
189 +    property TimeFormat: string;
190 +
191 +   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
192 +   DATETIME and TIME. The format strings use the standard FPC date/time format
193 +   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
194 +
195 +   If any of the above properties are set to an empty string, then the locale default
196 +   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
197 +   locale default is extended by appending '.zzz' to include milliseconds.
198 +
199 +   TIBCSVDataOut by default sets these properties to the empty string, while the other
200 +   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
201 +
202 + 5. New published property for TIBCSVDataOut:
203 +     property QuoteStrings: boolean (default true)
204 +
205 +   If false then strings are unquoted, otherwise, the QuoteChar property value is
206 +   used to delimit each and every string in the output.
207 +
208 + 6. New published properties for TIBCSVDataOut:
209 +    property FieldSeparator: string;
210 +    property HeaderSeparator: string;
211 +
212 +   Respectively, these provide the separator character(s) used to separate fields
213 +   in data and header rows. Both default to ','.
214 +
215 + 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
216 +    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
217 +    property OnFormatTextString;
218 +
219 +   This event handler can be used to process text strings before they are included
220 +   in the output e.g. to replace unprintable characters with alternative strings.
221 +   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
222 +
223 + 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
224 +   Uses "FindParam" if in order to find out if a parameter with a given name exists
225 +   and without raising and exception if it does not.
226 +
227 + 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
228 +   consistency with SQL queries.
229 +
230 + 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
231 +    When true, SQL statement parameter names are parsed case sensitive. Note for
232 +    TIBDataSet only applies to Select query.
233 +
234 + 11. IBEvents: removing a TIBEvent component from a form should no longer result in
235 +    an IDE exception.
236 +
237 + 12. LocalDBSupport: initial database creation should now work correctly
238 +    when the schema source is an sql file.
239 +
240 + 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
241 +    when defined, this handler will be called by the internal TIBXScript during
242 +    initial database creation when the schema source is an sql file and may be used
243 +    to provide a visual indication of progress in console mode.
244 +
245 + 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
246 +    to true while a new local database is being created and its schema populated.
247 +    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
248 +    when the database is disconnected/connected during the create DB procedure.
249 +
250 + 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
251 +    are now always ignored and replaced by the user name and password provided as
252 +    the login parameters for the TIBDatabase referenced from the TIBXScript. The
253 +    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
254 +    completely ignored if this property is true.
255 +
256 + 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
257 +    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
258 +    ImageIndex and SelectImageIndex values on AddNode.
259 +
260 + 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
261 +    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
262 +    the same database connection.
263 +
264 + 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
265 +    if provided, this should be an conditional SQL expression suitable for
266 +    including in an SQL Select statement "where" clause. If non-empty and the
267 +    "Filtered" property is true then the SQL expression provided as the value of
268 +    the "Filter" property is "ANDed" with any existing condition statement
269 +    in the SQL statement's "Where" clause.
270 +
271 +    If the "Filter" property is set at run time, the "Filtered" property is true
272 +    and the dataset is already open, then the dataset is closed and re-opened automatically.
273 +
274 +    The "Filter" condition may include IBX style parameters. In which case, their
275 +    value must be set by the dataset's "OnBeforeOpen" event handler.
276 +
277 +    This is a public property for TIBDataSet and TIBQuery query and intended for
278 +    use at run time.
279 +
280 +    Note: The property is a published property of TIBTable. The TIBTable functionality
281 +    is unaffected by this change.
282 +
283 + IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
284 +
285 + 1. Remove need to check for IsMultiThread by providing access to GUI timers via
286 +   IBGUIInterface. Note: master/detail delay timer does not apply to console
287 +   mode apps.
288 +
289 + 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
290 +   statement. This avoids problems if "Execute Block" is used as the Query.
291 +
292 + 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
293 +   internal SQL tokeniser routines.
294 +
295 + 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
296 +   as a select statement, with or without CTEs.
297 +
298 + 5. IBSQLParser: parser now recognises the "ROWS" clause.
299 +
300 + 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
301 +   internal SQL tokeniser routines.
302 +
303 + 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
304 +    being raised for valid set statements processed by a data formatter.
305 +
306 + 8. New published property for TIBDatabase and TIBXServicesConnection. This is
307 +   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
308 +   the path of the Firebird Library used by the database/services connection.
309 +
310 + 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
311 +   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
312 +   services connection.
313 +
314 + 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
315 +   or param name is not a valid SQL identifier.
316 +
317 + 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
318 +    view of whether the text box should be editable when no DataSource is specified.
319 +    TIBLookupComboEditBox has been updated to workaround this problem. As long as
320 +    ReadOnly is false, the text box is editable when no DataSource is specified.
321 +
322 + 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
323 +    the FBLIB environment variable. If you do not want to permit this then you
324 +    must modify the Register procedure in the design/IBDBReg.pas unit to remove
325 +    this setting.
326 +
327 + IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
328 +
329 + 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
330 +   Utf8EscapeControlChars
331 +
332   IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
