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