3 < 1. TIBDatabase.CreateDatabase: extract full DB Name using reg ex in order to
3 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
4 >   and is used to override the default settings in the client side "firebird.conf" This
5 >   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
6 >   Each line of the string list should be a setting in the same format as "firebird.conf".
7 >   For example "WireCompression = true" in order to request wire compression on the client side.
8 >
9 >   Note: explicit settings in the client side "firebird.conf" appear to take precedence
10 >   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
11 >   also require a compatible setting in the server side "firebird.conf". For example
12 >   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
13 >   compression to be used.
14 >
15 >   Whether or not WireCompression or WireCrypt are in use can be checked using the information
16 >   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
17 >   ibx/examples/dbinfo for examples of how to display this information.
18 >
19 > 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
20 >   is a "convenience" property. If set the "WireCompression=true" is added to the
21 >   ConfigOverrides. If unchecked then this setting is removed.
22 >
23 > 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
24 >   not "INT64".
25 >
26 > 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
27 >   These are:
28 >    property TimestampFormat: string;
29 >    property DateFormat: string;
30 >    property TimeFormat: string;
31 >
32 >   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
33 >   DATETIME and TIME. The format strings use the standard FPC date/time format
34 >   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
35 >
36 >   If any of the above properties are set to an empty string, then the locale default
37 >   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
38 >   locale default is extended by appending '.zzz' to include milliseconds.
39 >
40 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
41 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
42 >
43 > 5. New published property for TIBCSVDataOut:
44 >     property QuoteStrings: boolean (default true)
45 >
46 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
47 >   used to delimit each and every string in the output.
48 >
49 > 6. New published properties for TIBCSVDataOut:
50 >    property FieldSeparator: string;
51 >    property HeaderSeparator: string;
52 >
53 >   Respectively, these provide the separator character(s) used to separate fields
54 >   in data and header rows. Both default to ','.
55 >
56 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
57 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
58 >    property OnFormatTextString;
59 >
60 >   This event handler can be used to process text strings before they are included
61 >   in the output e.g. to replace unprintable characters with alternative strings.
62 >   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
63 >
64 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
65 >
66 > 9. TIBQuery now uses IBX SQL Parser instead of TParams SQL parser in order to ensure
67 >   consistency with SQL queries.
68 >
69 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
70 >    When true, SQL statement parameter names are parsed case sensitive. Note for
71 >    TIBDataSet only applies to Select query.
72 >
73 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
74 >    an IDE exception.
75 >
76 > IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
77 >
78 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
79 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
80 >   mode apps.
81 >
82 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
83 >   statement. This avoids problems if "Execute Block" is used as the Query.
84 >
85 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
86 >   internal SQL tokeniser routines.
87 >
88 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
89 >   as a select statement, with or without CTEs.
90 >
91 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
92 >
93 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
94 >   internal SQL tokeniser routines.
95 >
96 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
97 >    being raised for valid set statements processed by a data formatter.
98 >
99 > 8. New published property for TIBDatabase and TIBXServicesConnection. This is
100 >   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
101 >   the path of the Firebird Library used by the database/services connection.
102 >
103 > 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
104 >   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
105 >   services connection.
106 >
107 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
108 >   or param name is not a valid SQL identifier.
109 >
110 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
111 >    view of whether the text box should be editable when no DataSource is specified.
112 >    TIBLookupComboEditBox has been updated to workaround this problem. As long as
113 >    ReadOnly is false, the text box is editable when no DataSource is specified.
114 >
115 > 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
116 >    the FBLIB environment variable. If you do not want to permit this then you
117 >    must modify the Register procedure in the design/IBDBReg.pas unit to remove
118 >    this setting.
119 >

121 >
122 > 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
123 >   Utf8EscapeControlChars
124 >
125 > IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
126 >
127 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
128 > all previous copies of the IBX source code tree before installing this release.
129 >
130 > The IBX packages used by most users have not changed, with one exception. The
131 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
132 > to use the IBServices unit in your applications, please add the iblegacyServices
133 > to the list of dependencies. To do this, open the Project Inspector and select
134 > Add->New Requirement and select "ibLegacyServices" from the list of available
135 > packages.
136 >
137 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
138 >   the IBServices unit providing what is intended to be a clearer and easier to
139 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
140 >   more information and the guide to "Firebird Service Management Using IBX".
141 >   As indicated above, the legacy services components are still available and
142 >   provided in a separate package. There is no need to update working applications
143 >   using the older versions except for an additional package dependency.
144 >
145 > 2. The IBX packages and source code tree have been re-organised in an attempt to
146 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
147 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
148 >   new set of IBX packages.
149 >
150 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
151 >   updated to use the new Services API components.
152 >
153 > 4. The iblocal package has been updated to use the new Services API components.
154 >
155 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
156 >   TIBXSecurityService. It had been wrongly classified in the previous version
157 >   as a per database configuration item. It is global to a server and hence
158 >   correctly positioned as part of the Security Package. In the DBAdmin example,
159 >   the setting has moved to the mappings page.
160 >
161 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
162 >   are ignored.
163 >
164 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
165 >   closed before the database is dropped. Before and After Disconnect event handlers
166 >   are also fired.
167 >
168 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
169 >   is started and not just the first time.
170 >
171 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
172 >   depenendency with comp type.
173 >
174 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
175 >
176 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
177 >    then this is recognised and not ignored.
178 >
179 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
180 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
181 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
182 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
183 >
184 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
185 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
186 >    counters for the select query. Note: stats accumulate after each fetch from
187 >    the database. To get total query cost after open, call the "Last" method
188 >    and then GetPerfStatistics.
189 >
190 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
191 >
192 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
193 >    in parenthesises.
194 >
195 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
196 >    SQL identifiers are always delimited by double quotes. If false, then they are
197 >    only delimited if the identifier is a reserved word, contains lower case or special
198 >    characters. Set this property to true to retain previous behaviour.
199 >
200 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
201 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
202 >
203 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
204 >       property MasterDetailDelay: integer {defaults to zero}
205 >
206 >    When non-zero and the dataset is a detail table referencing a master table
207 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
208 >    then a synchronisation delay is added (in milliseconds) between the master
209 >    row changing and the detail dataset being re-opened. If the master dataset
210 >    is scrolled before the delay expires then the delay is reset. This can be used
211 >    to avoid performance overheads when scrolling through a large master dataset.
212 >
213 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
214 >    chreads unit must be included in your project. TTimer is not used in order
215 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
216 >
217 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
218 >    with Extract Option eoDatabase.
219 >
220 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
221 >    When a deLayoutChanged event is reported on the ListSource dataset, the
222 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
223 >    relationship with the control's datasource (master).
224 >
225 > 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
226 >
227 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
228 >    stubs. Pedantic fix really, as procedures output in dependency order anyway.
229 >
230 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
231 >    DDL (Firebird 3 and later only).
232 >
233 > 22. TIBLookupComboBox Autocomplete Fixes:
234 >    i. Only appended text is now selected after autocomplete.
235 >    ii. Uppercase keys no longer ignored for autocomplete.
236 >    iii. Retain Prefix case is now honoured correctly.
237 >    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
238 >        before autocomplete performed. i.e. behaviour now the same as when
239 >        no DataSource assigned.
240 >
241 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
242 >    between SQL statements.
243 >
244 > 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
245 >    ObjectNames are converted to upper case before matching against metadata object
246 >    names, unless the objectname is delimited by double quotes, in which case, the
247 >    double quotes are removed and the remaining string is used (unmodified) to match
248 >    against the metadata object name.
249 >
250 >    If true then the ObjectName is used as is without modification and matched
251 >    against the metadata object name. No attempt is made to remove double quotes.
252 >
253 > 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
254 >    with eoTrigger, these extract types can be used to select only Database Triggers,
255 >    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
256 >
257 > 26. TIBXScript: If an exception occurs during the processing of a statement, the
258 >    statement separate character is now reset to the default (';').
259 >
260 > 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
261 >
262 > 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
263 >    a commit or reconnect statement and instead activated only when next SQL statement
264 >    is executed.
265 >
266 > 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
267 >
268 > 30. TIBXScript: case insensitive regex now used when matching statements instead of
269 >    converting statement to upper case.
270 >
271 > 31. TIBExtract: metadata comments now supported. New published property
272 >    IncludeMetaDataComments (default true). If true then metadata comments included
273 >    in extracted DDL. New Extract Object member eoComments. This may be used with
274 >    ExtractObject method to list all metadata comments.
275 >
276 > 32. TIBExtract: ListObjectNames method added.
277 >
278 > 33. Updated Database component editor to support additional connection string
279 >    types.
280 >
281 > IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
282 >
283 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
284 > AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
285 > RELEASE.
286 >
287 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
288 >
289 > 1. IBExtract: Identity columns - add additional check for null column for generator name.
290 >
291 > 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
292 >   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
293 >   information). However, this is also a very useful mechanism for returning updated computed by
294 >   column values. Values returned as a result of executing an Insert or Update statement
295 >   replace existing values in the current row for each corresponding column.
296 >
297 >   Previously, if a dataset's select query included read only (computed by) fields then
298 >   an automatic row refresh was performed after an insert or update query had been processed,
299 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
300 >   that an automatic refresh is no longer performed if an insert or update query contains
301 >   a returning clause that updates one or more fields on the current row. A full row
302 >   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
303 >   field values and the select query contains read only fields. Use of Insert/update
304 >   returning should be significantly more efficient than executing a refresh query.
305 >
306 >   This behaviour change is intended to be backwards compatible and there should be no need to change
307 >   existing programs, other than to improve performance by using the new capability.
308 >
309 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
310 >   they are called when the dataset row is being deleted, there is no value in
311 >   updating the current record from the query result. Instead, a new event handler
312 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
313 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
314 >   by the query. The event handler can then interrogate the query results and
315 >   perform whatever action is necessary. For example to confirm, to the user,
316 >   the deletion of a row with the returned values.
317 >
318 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
319 >   any Computed By or Identity Columns. The IBTables example has been updated to
320 >   illustrate the computation of the employee Full Name on update.
321 >
322 > 5. TIBTable: The GeneratorField property is now published.
323 >
324 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
325 >   When InsertSQL is generated, the Identity columns are not included in the list of values to
326 >   be inserted. A RETURNING clause is added to the insert statement to return the value of
327 >   each Identity column after the insert is executed.
328 >
329 > 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
330 >   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
331 >   Insert..Returning clause.
332 >
333 > 8. TIBGenerator: small performance improvement by not preparing query each time
334 >   a new value is generated.
335 >
336 > 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
337 >
338 > 10. Property editors will now sync table name to a System Table when "Include System
339 >    Tables" is selected and the query is for a System Table.
340 >
341 > 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
342 >    values are no longer converted to milliseconds from TDateTime and then back again
343 >    to TDateTime (the conversion to milliseconds is the default TDataset approach).
344 >
345 > 12. Property Editors handling of Stored Procedures.
346 >    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
347 >      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
348 >      query).
349 >    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
350 >
351 > 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
352 >    can be used to select a package. If non-empty, the stored procedure name is
353 >    expected to be a stored procedure defined in the specified package and the
354 >    generated SQL will be as required for a stored procedure located in a package.
355 >
356 > 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
357 >    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
358 >    which a stored procedure can be selected. With no package name selected, non-package
359 >    stored procedures are listed.
360 >
361 > 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
362 >    for password on reconnect.
363 >
364 > 16. TIBDatabase: use IAttachment for connection default character set id, code page
365 >    and character set name.
366 >
367 > 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
368 >    DB info lookups"
369 >
370 > 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
371 >
372 > 19. Add a property Editor for TIBUpdate.RefreshSQL.
373 >
374 > 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
375 >    parameters. This stops an exception being raised when the field cannot be
376 >    located in the record buffer.
377 >
378 > 21. Property Editors now automatically include System Tables when opened and when the query table
379 >    is a System Table.
380 >
381 > 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
382 >    This avoids errors due to a stale SQRB or SRB being used for the next query.
383 >
384 > 23. IBServices: Service attach parameters now include "expected_db". This is used to
385 >    add the SPB item isc_spb_expected_db. This names a database using
386 >    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
387 >    database. examples/services re-written to illustrate use of "expected_db".
388 >
389 > 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
390 >    This avoids truncated backups when the server returns a timeout (busy) response.
391 >
392 > 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
393 >
394 > 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
395 >    databasenames. These are respectively expanded to the local system's temp directory
396 >    (including trailing delimiter) or to a prescribed data directory (including
397 >    trailing delimiter). Under Unix systems the data directory is a hidden directory
398 >    in the user's home directory. The hidden directory name is either the string returned
399 >    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
400 >    Under Windows, the directory is the same as the Data Directory as decribed
401 >    above but instead prefixed by the User's application data path. These may be
402 >    used to improve application portability for Personal Databases.
403 >
404 > 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
405 >    this has not worked for a long time and is not useful either. FieldDefs should be
406 >    managed using the Fields Editor as with any other dataset. To access the fields
407 >    editor for a TIBTable component, double click on the component. The fields editor
408 >    is then displayed.
409 >
410 > 28. TIBDatabaseInfo: new properties/function
411 >     * DateDBCreated (returns date/time database created)
412 >     * TransactionCount (returns no. of active transactions)
413 >     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).

546 >
547 > 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.

569 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
570 +   purpose and allows the programmer to define any action they want for Update, Insert
571 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
572 +   filtering of updates, or use of statements such as Grant or Revoke instead of
573 +   normal DML. See User Manual for more information.
