3 < 1. IBExtract: Identity columns - add addition check for null column for generator name.
3 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
4 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
5 >   mode apps.
6 >
7 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
8 >   statement. This avoids problems if "Execute Block" is used as the Query.
9 >
10 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
11 >   internal SQL tokeniser routines.
12 >
13 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
14 >   as a select statement, with or without CTEs.
15 >
16 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
17 >
18 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
19 >   internal SQL tokeniser routines.
20 >
21 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
22 >    being raised for valid set statements processed by a data formatter.
23 >
24 > 8. New published property for TIBDatabase and TIBXServicesConnection. This is
25 >   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
26 >   the path of the Firebird Library used by the database/services connection.
27 >
28 > 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
29 >   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
30 >   services connection.
31 >
32 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
33 >   or param name is not a valid SQL identifier.
34 >
35 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
36 >    view of whether the text box should be editable when no DataSource is specified.
37 >    TIBLookupComboEditBox has been updated to workaround this problem. As long as
38 >    ReadOnly is false, the text box is editable when no DataSource is specified.
39 >
40 > 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
41 >    the FBLIB environment variable. If you do not want to permit this then you
42 >    must modify the Register procedure in the design/IBDBReg.pas unit to remove
43 >    this setting.
44 >
45 > IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
46 >
47 > 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
48 >   Utf8EscapeControlChars
49 >
50 > IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
51 >
52 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
53 > all previous copies of the IBX source code tree before installing this release.
54 >
55 > The IBX packages used by most users have not changed, with one exception. The
56 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
57 > to use the IBServices unit in your applications, please add the iblegacyServices
58 > to the list of dependencies. To do this, open the Project Inspector and select
59 > Add->New Requirement and select "ibLegacyServices" from the list of available
60 > packages.
61 >
62 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
63 >   the IBServices unit providing what is intended to be a clearer and easier to
64 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
65 >   more information and the guide to "Firebird Service Management Using IBX".
66 >   As indicated above, the legacy services components are still available and
67 >   provided in a separate package. There is no need to update working applications
68 >   using the older versions except for an additional package dependency.
69 >
70 > 2. The IBX packages and source code tree have been re-organised in an attempt to
71 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
72 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
73 >   new set of IBX packages.
74 >
75 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
76 >   updated to use the new Services API components.
77 >
78 > 4. The iblocal package has been updated to use the new Services API components.
79 >
80 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
81 >   TIBXSecurityService. It had been wrongly classified in the previous version
82 >   as a per database configuration item. It is global to a server and hence
83 >   correctly positioned as part of the Security Package. In the DBAdmin example,
84 >   the setting has moved to the mappings page.
85 >
86 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
87 >   are ignored.
88 >
89 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
90 >   closed before the database is dropped. Before and After Disconnect event handlers
91 >   are also fired.
92 >
93 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
94 >   is started and not just the first time.
95 >
96 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
97 >   depenendency with comp type.
98 >
99 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
100 >
101 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
102 >    then this is recognised and not ignored.
103 >
104 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
105 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
106 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
107 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
108 >
109 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
110 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
111 >    counters for the select query. Note: stats accumulate after each fetch from
112 >    the database. To get total query cost after open, call the "Last" method
113 >    and then GetPerfStatistics.
114 >
115 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
116 >
117 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
118 >    in parenthesises.
119 >
120 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
121 >    SQL identifiers are always delimited by double quotes. If false, then they are
122 >    only delimited if the identifier is a reserved word, contains lower case or special
123 >    characters. Set this property to true to retain previous behaviour.
124 >
125 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
126 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
127 >
128 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
129 >       property MasterDetailDelay: integer {defaults to zero}
130 >
131 >    When non-zero and the dataset is a detail table referencing a master table
132 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
133 >    then a synchronisation delay is added (in milliseconds) between the master
134 >    row changing and the detail dataset being re-opened. If the master dataset
135 >    is scrolled before the delay expires then the delay is reset. This can be used
136 >    to avoid performance overheads when scrolling through a large master dataset.
137 >
138 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
139 >    chreads unit must be included in your project. TTimer is not used in order
140 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
141 >
142 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
143 >    with Extract Option eoDatabase.
144 >
145 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
146 >    When a deLayoutChanged event is reported on the ListSource dataset, the
147 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
148 >    relationship with the control's datasource (master).
149 >
150 > 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
151 >
152 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
153 >    stubs. Pedantic fix really, as procedures output in dependency order anyway.
154 >
155 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
156 >    DDL (Firebird 3 and later only).
157 >
158 > 22. TIBLookupComboBox Autocomplete Fixes:
159 >    i. Only appended text is now selected after autocomplete.
160 >    ii. Uppercase keys no longer ignored for autocomplete.
161 >    iii. Retain Prefix case is now honoured correctly.
162 >    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
163 >        before autocomplete performed. i.e. behaviour now the same as when
164 >        no DataSource assigned.
165 >
166 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
167 >    between SQL statements.
168 >
169 > 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
170 >    ObjectNames are converted to upper case before matching against metadata object
171 >    names, unless the objectname is delimited by double quotes, in which case, the
172 >    double quotes are removed and the remaining string is used (unmodified) to match
173 >    against the metadata object name.
174 >
175 >    If true then the ObjectName is used as is without modification and matched
176 >    against the metadata object name. No attempt is made to remove double quotes.
177 >
178 > 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
179 >    with eoTrigger, these extract types can be used to select only Database Triggers,
180 >    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
181 >
182 > 26. TIBXScript: If an exception occurs during the processing of a statement, the
183 >    statement separate character is now reset to the default (';').
184 >
185 > 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
186 >
187 > 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
188 >    a commit or reconnect statement and instead activated only when next SQL statement
189 >    is executed.
190 >
191 > 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
192 >
193 > 30. TIBXScript: case insensitive regex now used when matching statements instead of
194 >    converting statement to upper case.
195 >
196 > 31. TIBExtract: metadata comments now supported. New published property
197 >    IncludeMetaDataComments (default true). If true then metadata comments included
198 >    in extracted DDL. New Extract Object member eoComments. This may be used with
199 >    ExtractObject method to list all metadata comments.
200 >
201 > 32. TIBExtract: ListObjectNames method added.
202 >
203 > 33. Updated Database component editor to support additional connection string
204 >    types.
205 >
206 > IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
207 >
208 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
209 > AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
210 > RELEASE.
211 >
212 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
213 >
214 > 1. IBExtract: Identity columns - add additional check for null column for generator name.
215  
216   2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
217     The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
218 <   information). Values returned as a result of executing an Insert or Update statement
219 <   replace existing values in the current row for each corresponding column.
218 >   information). However, this is also a very useful mechanism for returning updated computed by
219 >   column values. Values returned as a result of executing an Insert or Update statement
220 >   replace existing values in the current row for each corresponding column.
221 >
222 >   Previously, if a dataset's select query included read only (computed by) fields then
223 >   an automatic row refresh was performed after an insert or update query had been processed,
224 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
225 >   that an automatic refresh is no longer performed if an insert or update query contains
226 >   a returning clause that updates one or more fields on the current row. A full row
227 >   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
228 >   field values and the select query contains read only fields. Use of Insert/update
229 >   returning should be significantly more efficient than executing a refresh query.
230  
231 < 3. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
231 >   This behaviour change is intended to be backwards compatible and there should be no need to change
232 >   existing programs, other than to improve performance by using the new capability.
233 >
234 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
235 >   they are called when the dataset row is being deleted, there is no value in
236 >   updating the current record from the query result. Instead, a new event handler
237 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
238 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
239 >   by the query. The event handler can then interrogate the query results and
240 >   perform whatever action is necessary. For example to confirm, to the user,
241 >   the deletion of a row with the returned values.
242 >
243 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
244 >   any Computed By or Identity Columns. The IBTables example has been updated to
245 >   illustrate the computation of the employee Full Name on update.
246 >
247 > 5. TIBTable: The GeneratorField property is now published.
248 >
249 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
250     When InsertSQL is generated, the Identity columns are not included in the list of values to
251     be inserted. A RETURNING clause is added to the insert statement to return the value of
252     each Identity column after the insert is executed.
253  
254 + 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
255 +   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
256 +   Insert..Returning clause.
257 +
258 + 8. TIBGenerator: small performance improvement by not preparing query each time
259 +   a new value is generated.
260 +
261 + 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
262 +
263 + 10. Property editors will now sync table name to a System Table when "Include System
264 +    Tables" is selected and the query is for a System Table.
265 +
266 + 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
267 +    values are no longer converted to milliseconds from TDateTime and then back again
268 +    to TDateTime (the conversion to milliseconds is the default TDataset approach).
269 +
270 + 12. Property Editors handling of Stored Procedures.
271 +    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
272 +      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
273 +      query).
274 +    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
275 +
276 + 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
277 +    can be used to select a package. If non-empty, the stored procedure name is
278 +    expected to be a stored procedure defined in the specified package and the
279 +    generated SQL will be as required for a stored procedure located in a package.
280 +
281 + 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
282 +    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
283 +    which a stored procedure can be selected. With no package name selected, non-package
284 +    stored procedures are listed.
285 +
286 + 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
287 +    for password on reconnect.
288 +
289 + 16. TIBDatabase: use IAttachment for connection default character set id, code page
290 +    and character set name.
291 +
292 + 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
293 +    DB info lookups"
294 +
295 + 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
296 +
297 + 19. Add a property Editor for TIBUpdate.RefreshSQL.
298 +
299 + 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
300 +    parameters. This stops an exception being raised when the field cannot be
301 +    located in the record buffer.
302 +
303 + 21. Property Editors now automatically include System Tables when opened and when the query table
304 +    is a System Table.
305 +
306 + 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
307 +    This avoids errors due to a stale SQRB or SRB being used for the next query.
308 +
309 + 23. IBServices: Service attach parameters now include "expected_db". This is used to
310 +    add the SPB item isc_spb_expected_db. This names a database using
311 +    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
312 +    database. examples/services re-written to illustrate use of "expected_db".
313 +
314 + 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
315 +    This avoids truncated backups when the server returns a timeout (busy) response.
316 +
317 + 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
318 +
319 + 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
320 +    databasenames. These are respectively expanded to the local system's temp directory
321 +    (including trailing delimiter) or to a prescribed data directory (including
322 +    trailing delimiter). Under Unix systems the data directory is a hidden directory
323 +    in the user's home directory. The hidden directory name is either the string returned
324 +    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
325 +    Under Windows, the directory is the same as the Data Directory as decribed
326 +    above but instead prefixed by the User's application data path. These may be
327 +    used to improve application portability for Personal Databases.
328 +
329 + 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
330 +    this has not worked for a long time and is not useful either. FieldDefs should be
331 +    managed using the Fields Editor as with any other dataset. To access the fields
332 +    editor for a TIBTable component, double click on the component. The fields editor
333 +    is then displayed.
334 +
335 + 28. TIBDatabaseInfo: new properties/function
336 +     * DateDBCreated (returns date/time database created)
337 +     * TransactionCount (returns no. of active transactions)
338 +     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
339 +     * PagesFree (Firebird 3 or later)
340 +     * PagesUsed (Firebird 3 or later)
341 +     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
342 +     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
343 +
344 + 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
345 +
346 + 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
347 +
348 + 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
349 +    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
350 +
351 + 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
352 +    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
353 +    firing during backup and restore.
354 +
355 + 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
356 +    for verbose output using the new property "StatisticsRequested".
357 +    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
358 +
359 + 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
360 +
361 + 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
362 +    palette. This uses the online validation feature added in Firebird 2.5. The
363 +    services's properties enable inclusion/exclusion of tables and indexes using
364 +    regular expressions. See.
365 +    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
366 +
367 + 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
368 +    option on a database.
369 +
370 + 37. TIBCustomService: Assign method implemented to allow copying of service login
371 +    context between service API components. "Detach" method now only detaches
372 +    service when last reference to the service interface detaches. Tidy up of
373 +    code for SetActive and Attach methods including password hiding.
374 +
375 + 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
376 +    and used to determine the auth method and protocol used for the connection.
377 +
378 + 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
379 +    a Create Database Statement generated by IBX.
380 +
381 + 40. All IBServices now have an additional published property "PortNo". This may
382 +    be set to a non-standard port number when necessary. If zero then the default
383 +    port number is used.
384 +
385 + 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
386 +    and not just the mouse.
387 +
388 + 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
389 +
390 + 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
391 +    image index and selected image index for each node to be set from a database field.
392 +
393 + 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
394 +    then database schema includes grants to all users. If not present then the
395 +    only user grants included are those to User PUBLIC.
396 +
397 + 45. TIBTreeView: performance improvement. When expanding include both expanded node
398 +    and child nodes in dataset.
399 +
