3	<	1. IBExtract: Identity columns - add addition check for null column for generator name.
3	>	This is rc1 for 2.2.3.
4	>
5	>	1. New property for TIBDatabase and TIBXServicesConnection. This is "WireCompression".
6	>	If this property is set to true then the Client will request WireCompression for
7	>	the connection. Note: "WireCompression = true" must be set in the server's
8	>	"firebird.conf". This property is overridden if "WireCompression = true" is set
9	>	in the client "firebird.conf" when wire compression is always requested by the client.

12	>
13	>	1. Remove need to check for IsMultiThread by providing access to GUI timers via
14	>	IBGUIInterface. Note: master/detail delay timer does not apply to console
15	>	mode apps.
16	>
17	>	2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
18	>	statement. This avoids problems if "Execute Block" is used as the Query.
19	>
20	>	3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
21	>	internal SQL tokeniser routines.
22	>
23	>	4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
24	>	as a select statement, with or without CTEs.
25	>
26	>	5. IBSQLParser: parser now recognises the "ROWS" clause.
27	>
28	>	6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
29	>	internal SQL tokeniser routines.
30	>
31	>	7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
32	>	being raised for valid set statements processed by a data formatter.
33	>
34	>	8. New published property for TIBDatabase and TIBXServicesConnection. This is
35	>	FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
36	>	the path of the Firebird Library used by the database/services connection.
37	>
38	>	9. New read only public property for TIBDatabase and TIBXServicesConnection. This
39	>	is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
40	>	services connection.
41	>
42	>	10.SQL Property editors now quote parameter names if "Quote identifier" is selected
43	>	or param name is not a valid SQL identifier.
44	>
45	>	11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
46	>	view of whether the text box should be editable when no DataSource is specified.
47	>	TIBLookupComboEditBox has been updated to workaround this problem. As long as
48	>	ReadOnly is false, the text box is editable when no DataSource is specified.
49	>
50	>	12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
51	>	the FBLIB environment variable. If you do not want to permit this then you
52	>	must modify the Register procedure in the design/IBDBReg.pas unit to remove
53	>	this setting.

61	>
62	>	IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
63	>	all previous copies of the IBX source code tree before installing this release.
64	>
65	>	The IBX packages used by most users have not changed, with one exception. The
66	>	IBServices unit has been moved to the package iblegacyServices.lpk. To continue
67	>	to use the IBServices unit in your applications, please add the iblegacyServices
68	>	to the list of dependencies. To do this, open the Project Inspector and select
69	>	Add->New Requirement and select "ibLegacyServices" from the list of available
70	>	packages.
71	>
72	>	1. New unit IBXServices. The IBXServices unit is a re-architectured update of
73	>	the IBServices unit providing what is intended to be a clearer and easier to
74	>	use set of IB Services components. See Chapter 10 of the IBX User Guide for
75	>	more information and the guide to "Firebird Service Management Using IBX".
76	>	As indicated above, the legacy services components are still available and
77	>	provided in a separate package. There is no need to update working applications
78	>	using the older versions except for an additional package dependency.
79	>
80	>	2. The IBX packages and source code tree have been re-organised in an attempt to
81	>	finally get rid of the "duplicate ppu" warnings. This re-organisation should
82	>	not affect existing users. Section 2.3 of the IBX User Guide describes the
83	>	new set of IBX packages.
84	>
85	>	3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
86	>	updated to use the new Services API components.
87	>
88	>	4. The iblocal package has been updated to use the new Services API components.
89	>
90	>	5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
91	>	TIBXSecurityService. It had been wrongly classified in the previous version
92	>	as a per database configuration item. It is global to a server and hence
93	>	correctly positioned as part of the Security Package. In the DBAdmin example,
94	>	the setting has moved to the mappings page.
95	>
96	>	6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
97	>	are ignored.
98	>
99	>	7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
100	>	closed before the database is dropped. Before and After Disconnect event handlers
101	>	are also fired.
102	>
103	>	8. TIBTransaction: OnStartTransaction event now fires every time the transaction
104	>	is started and not just the first time.
105	>
106	>	9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
107	>	depenendency with comp type.
108	>
109	>	10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
110	>
111	>	11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
112	>	then this is recognised and not ignored.
113	>
114	>	12. TIBDataSet, TIBQuery, TIBTable: additions:
115	>	function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
116	>	function GetPerfStatistics(var stats: TPerfCounters): boolean;
117	>	property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
118	>
119	>	GetRowsAffected returns the affected row counts from the last insert/update/delete
120	>	if EnableStatistics = true then GetPerfStatistics returns the current stats
121	>	counters for the select query. Note: stats accumulate after each fetch from
122	>	the database. To get total query cost after open, call the "Last" method
123	>	and then GetPerfStatistics.
124	>
125	>	See ibx/examples/consolemode for an example of the use of GetPerfStatistics
126	>
127	>	13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
128	>	in parenthesises.
129	>
130	>	14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
131	>	SQL identifiers are always delimited by double quotes. If false, then they are
132	>	only delimited if the identifier is a reserved word, contains lower case or special
133	>	characters. Set this property to true to retain previous behaviour.
134	>
135	>	15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
136	>	are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
137	>
138	>	16. TIBDataSet, TIBQuery, TIBTable: addition:
139	>	property MasterDetailDelay: integer {defaults to zero}
140	>
141	>	When non-zero and the dataset is a detail table referencing a master table
142	>	through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
143	>	then a synchronisation delay is added (in milliseconds) between the master
144	>	row changing and the detail dataset being re-opened. If the master dataset
145	>	is scrolled before the delay expires then the delay is reset. This can be used
146	>	to avoid performance overheads when scrolling through a large master dataset.
147	>
148	>	Note: uses fptimer and hence requires a thread manager. Under Linux the
149	>	chreads unit must be included in your project. TTimer is not used in order
150	>	to avoid an LCL dependency. Requires FPC 3.0.2 or later.
151	>
152	>	17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
153	>	with Extract Option eoDatabase.
154	>
155	>	18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
156	>	When a deLayoutChanged event is reported on the ListSource dataset, the
157	>	combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
158	>	relationship with the control's datasource (master).
159	>
160	>	19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
161	>
162	>	20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
163	>	stubs. Pedantic fix really, as procedures output in dependency order anyway.
164	>
165	>	21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
166	>	DDL (Firebird 3 and later only).
167	>
168	>	22. TIBLookupComboBox Autocomplete Fixes:
169	>	i. Only appended text is now selected after autocomplete.
170	>	ii. Uppercase keys no longer ignored for autocomplete.
171	>	iii. Retain Prefix case is now honoured correctly.
172	>	iv. When a DataSource is assigned, typing after autocomplete now extends prefix
173	>	before autocomplete performed. i.e. behaviour now the same as when
174	>	no DataSource assigned.
175	>
176	>	23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
177	>	between SQL statements.
178	>
179	>	24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
180	>	ObjectNames are converted to upper case before matching against metadata object
181	>	names, unless the objectname is delimited by double quotes, in which case, the
182	>	double quotes are removed and the remaining string is used (unmodified) to match
183	>	against the metadata object name.
184	>
185	>	If true then the ObjectName is used as is without modification and matched
186	>	against the metadata object name. No attempt is made to remove double quotes.
187	>
188	>	25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
189	>	with eoTrigger, these extract types can be used to select only Database Triggers,
190	>	or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
191	>
192	>	26. TIBXScript: If an exception occurs during the processing of a statement, the
193	>	statement separate character is now reset to the default (';').
194	>
195	>	27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
196	>
197	>	28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
198	>	a commit or reconnect statement and instead activated only when next SQL statement
199	>	is executed.
200	>
201	>	29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
202	>
203	>	30. TIBXScript: case insensitive regex now used when matching statements instead of
204	>	converting statement to upper case.
205	>
206	>	31. TIBExtract: metadata comments now supported. New published property
207	>	IncludeMetaDataComments (default true). If true then metadata comments included
208	>	in extracted DDL. New Extract Object member eoComments. This may be used with
209	>	ExtractObject method to list all metadata comments.
210	>
211	>	32. TIBExtract: ListObjectNames method added.
212	>
213	>	33. Updated Database component editor to support additional connection string
214	>	types.
215	>
216	>	IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
217	>
218	>	NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
219	>	AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
220	>	RELEASE.
221	>
222	>	NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
223	>
224	>	1. IBExtract: Identity columns - add additional check for null column for generator name.
225
226		2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
227		The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
228	<	information). Values returned as a result of executing an Insert or Update statement
229	<	replace existing values in the current row for each corresponding column.
228	>	information). However, this is also a very useful mechanism for returning updated computed by
229	>	column values. Values returned as a result of executing an Insert or Update statement
230	>	replace existing values in the current row for each corresponding column.
231	>
232	>	Previously, if a dataset's select query included read only (computed by) fields then
233	>	an automatic row refresh was performed after an insert or update query had been processed,
234	>	irrespective of the setting of the "ForcedUpdates" property. This has changed such
235	>	that an automatic refresh is no longer performed if an insert or update query contains
236	>	a returning clause that updates one or more fields on the current row. A full row
237	>	refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
238	>	field values and the select query contains read only fields. Use of Insert/update
239	>	returning should be significantly more efficient than executing a refresh query.
240	>
241	>	This behaviour change is intended to be backwards compatible and there should be no need to change
242	>	existing programs, other than to improve performance by using the new capability.
243	>
244	>	3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
245	>	they are called when the dataset row is being deleted, there is no value in
246	>	updating the current record from the query result. Instead, a new event handler
247	>	"OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
248	>	an OnDeleteReturning event handler is provided then it is called with the IResults returned
249	>	by the query. The event handler can then interrogate the query results and
250	>	perform whatever action is necessary. For example to confirm, to the user,
251	>	the deletion of a row with the returned values.
252	>
253	>	4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
254	>	any Computed By or Identity Columns. The IBTables example has been updated to
255	>	illustrate the computation of the employee Full Name on update.
256
257	<	3. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
257	>	5. TIBTable: The GeneratorField property is now published.
258	>
259	>	6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
260		When InsertSQL is generated, the Identity columns are not included in the list of values to
261		be inserted. A RETURNING clause is added to the insert statement to return the value of
262		each Identity column after the insert is executed.
263
264	<	4. TIBGenerator: small performance improvement by not preparing query each time
265	<	a new number is generated.
264	>	7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
265	>	Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
266	>	Insert..Returning clause.
267	>
268	>	8. TIBGenerator: small performance improvement by not preparing query each time
269	>	a new value is generated.
270
271	<	5. TIBSQL: Free resources when transaction changed.
271	>	9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
272
273	<	6. Property editor will now sync table name to a System Table when "Include System
274	<	Tables" is selected and the query is for a System Table.
273	>	10. Property editors will now sync table name to a System Table when "Include System
274	>	Tables" is selected and the query is for a System Table.
275	>
276	>	11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
277	>	values are no longer converted to milliseconds from TDateTime and then back again
278	>	to TDateTime (the conversion to milliseconds is the default TDataset approach).
279	>
280	>	12. Property Editors handling of Stored Procedures.
281	>	* Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
282	>	which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
283	>	query).
284	>	* Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
285	>
286	>	13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
287	>	can be used to select a package. If non-empty, the stored procedure name is
288	>	expected to be a stored procedure defined in the specified package and the
289	>	generated SQL will be as required for a stored procedure located in a package.
290	>
291	>	14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
292	>	a "Package Name" drop down box to allow selection of a Firebird 3 Package from
293	>	which a stored procedure can be selected. With no package name selected, non-package
294	>	stored procedures are listed.
295	>
296	>	15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
297	>	for password on reconnect.
298	>
299	>	16. TIBDatabase: use IAttachment for connection default character set id, code page
300	>	and character set name.
301	>
302	>	17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
303	>	DB info lookups"
304	>
305	>	18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
306	>
307	>	19. Add a property Editor for TIBUpdate.RefreshSQL.
308	>
309	>	20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
310	>	parameters. This stops an exception being raised when the field cannot be
311	>	located in the record buffer.
312	>
313	>	21. Property Editors now automatically include System Tables when opened and when the query table
314	>	is a System Table.
315	>
316	>	22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
317	>	This avoids errors due to a stale SQRB or SRB being used for the next query.
318	>
319	>	23. IBServices: Service attach parameters now include "expected_db". This is used to
320	>	add the SPB item isc_spb_expected_db. This names a database using
321	>	an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
322	>	database. examples/services re-written to illustrate use of "expected_db".
323	>
324	>	24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
325	>	This avoids truncated backups when the server returns a timeout (busy) response.
326	>
327	>	25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
328	>
329	>	26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
330	>	databasenames. These are respectively expanded to the local system's temp directory
331	>	(including trailing delimiter) or to a prescribed data directory (including
332	>	trailing delimiter). Under Unix systems the data directory is a hidden directory
333	>	in the user's home directory. The hidden directory name is either the string returned
334	>	from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
335	>	Under Windows, the directory is the same as the Data Directory as decribed
336	>	above but instead prefixed by the User's application data path. These may be
337	>	used to improve application portability for Personal Databases.
338	>
339	>	27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
340	>	this has not worked for a long time and is not useful either. FieldDefs should be
341	>	managed using the Fields Editor as with any other dataset. To access the fields
342	>	editor for a TIBTable component, double click on the component. The fields editor
343	>	is then displayed.
344	>
345	>	28. TIBDatabaseInfo: new properties/function
346	>	* DateDBCreated (returns date/time database created)
347	>	* TransactionCount (returns no. of active transactions)
348	>	* GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
349	>	* PagesFree (Firebird 3 or later)
350	>	* PagesUsed (Firebird 3 or later)
351	>	* Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
352	>	* EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
353	>
354	>	29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
355	>
356	>	30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
357	>
358	>	31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
359	>	the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
360	>
361	>	32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
362	>	in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
363	>	firing during backup and restore.
364	>
365	>	33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
366	>	for verbose output using the new property "StatisticsRequested".
367	>	see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
368	>
369	>	34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
370	>
371	>	35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
372	>	palette. This uses the online validation feature added in Firebird 2.5. The
373	>	services's properties enable inclusion/exclusion of tables and indexes using
374	>	regular expressions. See.
375	>	https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
376	>
377	>	36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
378	>	option on a database.
379	>
380	>	37. TIBCustomService: Assign method implemented to allow copying of service login
381	>	context between service API components. "Detach" method now only detaches
382	>	service when last reference to the service interface detaches. Tidy up of
383	>	code for SetActive and Attach methods including password hiding.
