8 +
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). 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 + 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 + 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 + 8. TIBGenerator: small performance improvement by not preparing query each time
216 +   a new value is generated.
217 +
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 +
