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