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.
54 >
55 > IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
56 >
57 > 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
58 >   Utf8EscapeControlChars
59 >
60 > IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
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 > 5. TIBTable: The GeneratorField property is now published.
258  
259 < 3. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
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 < 5. TIBSQL: Free resources when transaction changed.
268 > 8. TIBGenerator: small performance improvement by not preparing query each time
269 >   a new value is generated.
270  
271 < 6. Property editor will now sync table name to a System Table when "Include System
21 <   Tables" is selected and the query is for a System Table.
271 > 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
272  
273 < 7. Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
274 <   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
275 <   Insert..Returning clause.
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.
384 >
385 > 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
386 >    and used to determine the auth method and protocol used for the connection.
387 >
388 > 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
389 >    a Create Database Statement generated by IBX.
390 >
391 > 40. All IBServices now have an additional published property "PortNo". This may
392 >    be set to a non-standard port number when necessary. If zero then the default
393 >    port number is used.
394 >
395 > 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
