3 < 1. IBExtract: Identity columns - add addition check for null column for generator name.
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 > IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
24 >
25 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
26 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
27 >   mode apps.
28 >
29 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
30 >   statement. This avoids problems if "Execute Block" is used as the Query.
31 >
32 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
33 >   internal SQL tokeniser routines.
34 >
35 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
36 >   as a select statement, with or without CTEs.
37 >
38 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
39 >
40 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
41 >   internal SQL tokeniser routines.
42 >
43 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
44 >    being raised for valid set statements processed by a data formatter.
45 >
46 > 8. New published property for TIBDatabase and TIBXServicesConnection. This is
47 >   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
48 >   the path of the Firebird Library used by the database/services connection.
49 >
50 > 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
51 >   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
52 >   services connection.
53 >
54 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
55 >   or param name is not a valid SQL identifier.
56 >
57 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
58 >    view of whether the text box should be editable when no DataSource is specified.
59 >    TIBLookupComboEditBox has been updated to workaround this problem. As long as
60 >    ReadOnly is false, the text box is editable when no DataSource is specified.
61 >
62 > 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
63 >    the FBLIB environment variable. If you do not want to permit this then you
64 >    must modify the Register procedure in the design/IBDBReg.pas unit to remove
65 >    this setting.
66 >
67 > IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
68 >
69 > 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
70 >   Utf8EscapeControlChars
71 >
72 > IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
73 >
74 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
75 > all previous copies of the IBX source code tree before installing this release.
76 >
77 > The IBX packages used by most users have not changed, with one exception. The
78 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
79 > to use the IBServices unit in your applications, please add the iblegacyServices
80 > to the list of dependencies. To do this, open the Project Inspector and select
81 > Add->New Requirement and select "ibLegacyServices" from the list of available
82 > packages.
83 >
84 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
85 >   the IBServices unit providing what is intended to be a clearer and easier to
86 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
87 >   more information and the guide to "Firebird Service Management Using IBX".
88 >   As indicated above, the legacy services components are still available and
89 >   provided in a separate package. There is no need to update working applications
90 >   using the older versions except for an additional package dependency.
91 >
92 > 2. The IBX packages and source code tree have been re-organised in an attempt to
93 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
94 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
95 >   new set of IBX packages.
96 >
97 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
98 >   updated to use the new Services API components.
99 >
100 > 4. The iblocal package has been updated to use the new Services API components.
101 >
102 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
103 >   TIBXSecurityService. It had been wrongly classified in the previous version
104 >   as a per database configuration item. It is global to a server and hence
105 >   correctly positioned as part of the Security Package. In the DBAdmin example,
106 >   the setting has moved to the mappings page.
107 >
108 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
109 >   are ignored.
110 >
111 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
112 >   closed before the database is dropped. Before and After Disconnect event handlers
113 >   are also fired.
114 >
115 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
116 >   is started and not just the first time.
117 >
118 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
119 >   depenendency with comp type.
120 >
121 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
122 >
123 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
124 >    then this is recognised and not ignored.
125 >
126 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
127 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
128 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
129 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
130 >
131 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
132 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
133 >    counters for the select query. Note: stats accumulate after each fetch from
134 >    the database. To get total query cost after open, call the "Last" method
135 >    and then GetPerfStatistics.
136 >
137 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
138 >
139 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
140 >    in parenthesises.
141 >
142 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
143 >    SQL identifiers are always delimited by double quotes. If false, then they are
144 >    only delimited if the identifier is a reserved word, contains lower case or special
145 >    characters. Set this property to true to retain previous behaviour.
146 >
147 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
148 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
149 >
150 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
151 >       property MasterDetailDelay: integer {defaults to zero}
152 >
153 >    When non-zero and the dataset is a detail table referencing a master table
154 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
155 >    then a synchronisation delay is added (in milliseconds) between the master
156 >    row changing and the detail dataset being re-opened. If the master dataset
157 >    is scrolled before the delay expires then the delay is reset. This can be used
158 >    to avoid performance overheads when scrolling through a large master dataset.
159 >
160 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
161 >    chreads unit must be included in your project. TTimer is not used in order
162 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
163 >
164 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
165 >    with Extract Option eoDatabase.
166 >
167 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
168 >    When a deLayoutChanged event is reported on the ListSource dataset, the
169 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
170 >    relationship with the control's datasource (master).
171 >
172 > 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
173 >
174 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
175 >    stubs. Pedantic fix really, as procedures output in dependency order anyway.
176 >
177 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
178 >    DDL (Firebird 3 and later only).
179 >
180 > 22. TIBLookupComboBox Autocomplete Fixes:
181 >    i. Only appended text is now selected after autocomplete.
182 >    ii. Uppercase keys no longer ignored for autocomplete.
183 >    iii. Retain Prefix case is now honoured correctly.
184 >    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
185 >        before autocomplete performed. i.e. behaviour now the same as when
186 >        no DataSource assigned.
187 >
188 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
189 >    between SQL statements.
190 >
191 > 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
192 >    ObjectNames are converted to upper case before matching against metadata object
193 >    names, unless the objectname is delimited by double quotes, in which case, the
194 >    double quotes are removed and the remaining string is used (unmodified) to match
195 >    against the metadata object name.
196 >
197 >    If true then the ObjectName is used as is without modification and matched
198 >    against the metadata object name. No attempt is made to remove double quotes.
199 >
200 > 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
201 >    with eoTrigger, these extract types can be used to select only Database Triggers,
202 >    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
203 >
204 > 26. TIBXScript: If an exception occurs during the processing of a statement, the
205 >    statement separate character is now reset to the default (';').
206 >
207 > 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
208 >
209 > 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
210 >    a commit or reconnect statement and instead activated only when next SQL statement
211 >    is executed.
212 >
213 > 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
214 >
215 > 30. TIBXScript: case insensitive regex now used when matching statements instead of
216 >    converting statement to upper case.
217 >
218 > 31. TIBExtract: metadata comments now supported. New published property
219 >    IncludeMetaDataComments (default true). If true then metadata comments included
220 >    in extracted DDL. New Extract Object member eoComments. This may be used with
221 >    ExtractObject method to list all metadata comments.
222 >
223 > 32. TIBExtract: ListObjectNames method added.
224 >
225 > 33. Updated Database component editor to support additional connection string
226 >    types.
227 >
228 > IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
229 >
230 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
231 > AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
232 > RELEASE.
233 >
234 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
235 >
236 > 1. IBExtract: Identity columns - add additional check for null column for generator name.
237  
238   2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
239     The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
240 <   information). Values returned as a result of executing an Insert or Update statement
241 <   replace existing values in the current row for each corresponding column.
240 >   information). However, this is also a very useful mechanism for returning updated computed by
241 >   column values. Values returned as a result of executing an Insert or Update statement
242 >   replace existing values in the current row for each corresponding column.
243 >
244 >   Previously, if a dataset's select query included read only (computed by) fields then
245 >   an automatic row refresh was performed after an insert or update query had been processed,
246 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
247 >   that an automatic refresh is no longer performed if an insert or update query contains
248 >   a returning clause that updates one or more fields on the current row. A full row
249 >   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
250 >   field values and the select query contains read only fields. Use of Insert/update
251 >   returning should be significantly more efficient than executing a refresh query.
252 >
253 >   This behaviour change is intended to be backwards compatible and there should be no need to change
254 >   existing programs, other than to improve performance by using the new capability.
255 >
256 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
257 >   they are called when the dataset row is being deleted, there is no value in
258 >   updating the current record from the query result. Instead, a new event handler
259 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
260 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
261 >   by the query. The event handler can then interrogate the query results and
262 >   perform whatever action is necessary. For example to confirm, to the user,
263 >   the deletion of a row with the returned values.
264 >
265 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
266 >   any Computed By or Identity Columns. The IBTables example has been updated to
267 >   illustrate the computation of the employee Full Name on update.
268 >
269 > 5. TIBTable: The GeneratorField property is now published.
270  
271 < 3. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
271 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
272     When InsertSQL is generated, the Identity columns are not included in the list of values to
273     be inserted. A RETURNING clause is added to the insert statement to return the value of
274     each Identity column after the insert is executed.
275  
276 < 4. TIBGenerator: small performance improvement by not preparing query each time
277 <   a new number is generated.
276 > 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
277 >   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
278 >   Insert..Returning clause.
279  
280 < 5. TIBSQL: Free resources when transaction changed.
280 > 8. TIBGenerator: small performance improvement by not preparing query each time
281 >   a new value is generated.
282  
283 < 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.
283 > 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
284  
285 < 7. Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
286 <   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
287 <   Insert..Returning clause.
285 > 10. Property editors will now sync table name to a System Table when "Include System
286 >    Tables" is selected and the query is for a System Table.
287 >
288 > 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
289 >    values are no longer converted to milliseconds from TDateTime and then back again
290 >    to TDateTime (the conversion to milliseconds is the default TDataset approach).
291 >
292 > 12. Property Editors handling of Stored Procedures.
293 >    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
294 >      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
295 >      query).
296 >    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
297 >
298 > 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
299 >    can be used to select a package. If non-empty, the stored procedure name is
300 >    expected to be a stored procedure defined in the specified package and the
301 >    generated SQL will be as required for a stored procedure located in a package.
302 >
303 > 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
304 >    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
305 >    which a stored procedure can be selected. With no package name selected, non-package
306 >    stored procedures are listed.
307 >
308 > 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
309 >    for password on reconnect.
310 >
311 > 16. TIBDatabase: use IAttachment for connection default character set id, code page
312 >    and character set name.
313 >
314 > 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
315 >    DB info lookups"
316 >
317 > 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
318 >
319 > 19. Add a property Editor for TIBUpdate.RefreshSQL.
320 >
321 > 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
322 >    parameters. This stops an exception being raised when the field cannot be
323 >    located in the record buffer.
324 >
325 > 21. Property Editors now automatically include System Tables when opened and when the query table
326 >    is a System Table.
327 >
328 > 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
329 >    This avoids errors due to a stale SQRB or SRB being used for the next query.
330 >
331 > 23. IBServices: Service attach parameters now include "expected_db". This is used to
332 >    add the SPB item isc_spb_expected_db. This names a database using
333 >    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
334 >    database. examples/services re-written to illustrate use of "expected_db".
335 >
336 > 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
337 >    This avoids truncated backups when the server returns a timeout (busy) response.
338 >
339 > 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
340 >
341 > 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
342 >    databasenames. These are respectively expanded to the local system's temp directory
343 >    (including trailing delimiter) or to a prescribed data directory (including
344 >    trailing delimiter). Under Unix systems the data directory is a hidden directory
345 >    in the user's home directory. The hidden directory name is either the string returned
346 >    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
347 >    Under Windows, the directory is the same as the Data Directory as decribed
348 >    above but instead prefixed by the User's application data path. These may be
349 >    used to improve application portability for Personal Databases.
350 >
351 > 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
352 >    this has not worked for a long time and is not useful either. FieldDefs should be
353 >    managed using the Fields Editor as with any other dataset. To access the fields
354 >    editor for a TIBTable component, double click on the component. The fields editor
355 >    is then displayed.
356 >
357 > 28. TIBDatabaseInfo: new properties/function
358 >     * DateDBCreated (returns date/time database created)
359 >     * TransactionCount (returns no. of active transactions)
360 >     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
361 >     * PagesFree (Firebird 3 or later)
362 >     * PagesUsed (Firebird 3 or later)
363 >     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
364 >     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
365 >
366 > 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
367 >
368 > 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
369 >
370 > 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
371 >    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
372 >
373 > 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
374 >    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
375 >    firing during backup and restore.
376 >
377 > 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
378 >    for verbose output using the new property "StatisticsRequested".
379 >    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
380 >
381 > 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
382 >
383 > 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
384 >    palette. This uses the online validation feature added in Firebird 2.5. The
385 >    services's properties enable inclusion/exclusion of tables and indexes using
386 >    regular expressions. See.
387 >    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
388 >
389 > 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
390 >    option on a database.
391 >
392 > 37. TIBCustomService: Assign method implemented to allow copying of service login
