3 > 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
4 >    not SQL Identifiers are now supported.
5 >
6 > 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
7 >    passed to the Firebird engine for execution.
8 >
9 > 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
10 >    is made to scroll back.

12 > 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
13 >
14 > 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
15 >   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
16 >
17 > 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
18 >   validated. If no match is found in the list of field names and the database has
19 >   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
20 >   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.

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