1 + IBX Change Log  version                                                    (2.2-0) Thu, 22 Feb 2018 17:12:26 +0000
2 +
3 + 1. IBExtract: Identity columns - add additional check for null column for generator name.
4 +
5 + 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
6 +   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
7 +   information). However, this is also a very useful mechanism for returning updated computed by
8 +   column values. Values returned as a result of executing an Insert or Update statement
9 +   replace existing values in the current row for each corresponding column.
10 +
11 +   Previously, if a dataset's select query included read only (computed by) fields then
12 +   an automatic row refresh was performed after an insert or update query had been processed,
13 +   irrespective of the setting of the "ForcedUpdates" property. This has changed such
14 +   that an automatic refresh is no longer performed if an insert or update query contains
15 +   a returning clause that updates one or more fields on the current row. A full row
16 +   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
17 +   field values and the select query contains read only fields. Use of Insert/update
18 +   returning should be significantly more efficient than executing a refresh query.
19 +
20 +   This behaviour change is intended to be backwards compatible and there should be no need to change
21 +   existing programs, other than to improve performance by using the new capability.
22 +
23 + 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
24 +   they are called when the dataset row is being deleted, there is no value in
25 +   updating the current record from the query result. Instead, a new event handler
26 +   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
27 +   an OnDeleteReturning event handler is provided then it is called with the IResults returned
28 +   by the query. The event handler can then interrogate the query results and
29 +   perform whatever action is necessary. For example to confirm, to the user,
30 +   the deletion of a row with the returned values.
31 +
32 + 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
33 +   any Computed By or Identity Columns. The IBTables example has been updated to
34 +   illustrate the computation of the employee Full Name on update.
35 +
36 + 5. TIBTable: The GeneratorField property is now published.
37 +
38 + 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
39 +   When InsertSQL is generated, the Identity columns are not included in the list of values to
40 +   be inserted. A RETURNING clause is added to the insert statement to return the value of
41 +   each Identity column after the insert is executed.
42 +
43 + 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
44 +   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
45 +   Insert..Returning clause.
46 +
47 + 8. TIBGenerator: small performance improvement by not preparing query each time
48 +   a new value is generated.
49 +
50 + 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
51 +
52 + 10. Property editors will now sync table name to a System Table when "Include System
53 +    Tables" is selected and the query is for a System Table.
54 +
55 + 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
56 +    values are no longer converted to milliseconds from TDateTime and then back again
57 +    to TDateTime (the conversion to milliseconds is the default TDataset approach).
58 +
59 + 12. Property Editors handling of Stored Procedures.
60 +    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
61 +      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
62 +      query).
63 +    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
64 +
65 + 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
66 +    can be used to select a package. If non-empty, the stored procedure name is
67 +    expected to be a stored procedure defined in the specified package and the
68 +    generated SQL will be as required for a stored procedure located in a package.
69 +
70 + 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
71 +    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
72 +    which a stored procedure can be selected. With no package name selected, non-package
73 +    stored procedures are listed.
74 +
75 + 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
76 +    for password on reconnect.
77 +
78 + 16. TIBDatabase: use IAttachment for connection default character set id, code page
79 +    and character set name.
80 +
81 + 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
82 +    DB info lookups"
83 +
84 + 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
85 +
86 + 19. Add a property Editor for TIBUpdate.RefreshSQL.
87 +
88 + 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
89 +    parameters. This stops an exception being raised when the field cannot be
90 +    located in the record buffer.
91 +
92 + 21. Property Editors now automatically include System Tables when opened and when the query table
93 +    is a System Table.
94 +
95 + 22. IBServices: SQRB and SRB buffers are now reset when service query throws and exception.
96 +    This avoids errors due to a stale SQRB or SRB being used for the next query.
97 +
98 + 23. IBServices: Service attach parameters now include "expected_db". This is used to
99 +    add the SPB item isc_spb_expected_db. This names a database using
100 +    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
101 +    database. examples/services re-written to illustrate use of "expected_db".
102 +
103 + 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
104 +    This avoids truncated backups when the server returns a timeout (busy) response.
105 +
106 + 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
107 +
108 + 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
109 +    databasenames. These are respectively expanded to the local system's temp directory
110 +    (including trailing delimiter) or to a directory a prescribed data directory (including
111 +    trailing delimiter). Under Unix systems the data directory is a hidden directory
112 +    in the user's home directory. The hidden directory name is either the string returned
113 +    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
114 +    Under Windows, the directory is the same as the Data Directory as decribed
115 +    above but instead prefixed by the User's application data path. These may be
116 +    used to improve application portability.
117 +
118 + 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
119 +    this has not worked for a long time and is not useful either. FieldDefs should be
120 +    managed using the Fields Editor as with any other dataset. To access the fields
121 +    editor for a TIBTable component, double click on the component. The fields editor
122 +    is then displayed.
123 +
124 + 28. TIBDatabaseInfo: new properties/function
125 +     * DateDBCreated (returns date/time database created)
126 +     * TransactionCount (returns no. of active transactions)
127 +     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
128 +     * PagesFree (Firebird 3 or later)
129 +     * PagesUsed (Firebird 3 or later)
130 +     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
131 +     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
132 +
133 + 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
134 +
135 + 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
136 +
137 + 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
138 +    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
139 +
140 + 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
141 +    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
142 +    firing during backup and restore.
143 +
144 + 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
145 +    for verbose output using the new property "StatisticsRequested".
146 +    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
147 +
148 + 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
149 +
150 + 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
151 +    palette. This uses the online validation feature added in Firebird 2.5. The
152 +    services's properties enable inclusion/exclusion of tables and indexes using
153 +    regular expressions. See.
154 +    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
155 +
156 + 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
157 +    option on a database.
158 +
159 + 37. TIBCustomService: Assign method implemented to allow copying of service login
160 +    context between service API components. "Detach" method now only detaches
161 +    service when last reference to the service interface detaches. Tidy up of
162 +    code for SetActive and Attach methods including password hiding.
163 +
164 + 38. TIBDatabase: new proterties: AuthenticationMethod and RemoteProtocol. Read only
165 +    and used to determine the auth method and protocol used for the connection.
166 +
167 + 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
168 +    a Create Database Statement generated by IBX.
169 +
170 + 40. All IBServices now have an additional published property "PortNo". This may
171 +    be set to a non-standard port number when necessary. If zero then the default
172 +    port number is used.
173 +
174 + 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
175 +    and not just the mouse.
176 +
177 + 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
178 +
179 + 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
180 +    image index and selected image index for each node to be set from a database field.
181 +
182 + 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
183 +    then database schema includes grants to all users. If not present then the
184 +    only user grants included are those to User PUBLIC.
185 +
186 + 45. TIBTreeView: performance improvement. When expanding include both expanded node
187 +    and child nodes in dataset.
188 +
189 +
190 + IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
191 +
192 + 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
193 +   changes.
194 +
195 + 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
196 +   Bug could result in truncated multi-byte character set values.
197 +
198 + 3. Changes consequential on moving fbintf character set utility functions from
199 +   IFirebirdAPI to IAttachment.
200 +
201 + 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
202 +
203 + 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
204 +   results in autocomplete ignoring prefix text.
205 +
206 + 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
207 +   entering a new name into the text box.
208 +
209 + 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
210 +   Firebird rather than recomputing it.
211 +
212 + 8. Property Editor positioning tidy up: All IBX Property editors should now be
213 +   screen centre. Previously some were "poDesigned" which may be inappropriate
214 +   for multi monitor desktops.
215 +
216 + 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
217 +
218 + 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
219 +    a transaction and always reset the object.
220 +
221 + 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
222 +
223 + 13. TIBXScript: Allow for override of database filename in Create Database statements.
224 +
225 + 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
226 +    to a gbak format archive.
227 +
228 + 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
229 +
230 + 16. IBLocaldb: Drop database if error creating an empty database.
231 +
232 + 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
233 +    unless selected node not in current dataset.
234 +
235 + 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
236 +    to TIBCustomService, and IBlocalDB code tidy up.
237 +
238 + 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
239 +    behaviour due to uninitialised variable.
240 +
241 + 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
242 +    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
243 +
244 + 21. IBSQL: When Database changed ensure that all resources are freed.
245 +
246 + 22. IBCustomDataset: When database changed ensure that queries an unprepared.
247 +
248 + 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
249 +    * Line Wrap on SQL Token boundaries (on user command)
250 +    * auto-complete table names in drop down list of table names
251 +    * Double click on tablename or field name adds to SQL text
252 +
253 + 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
254 +
255 + 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
256 +    TVariantArray. Seems to avoid memory corruption in Windows (probably a
257 +    workaround for a problem in fpc 3.0.4 win64).
258 +
259 + 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
260 +
261 + 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
262 +
263   IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
264  
265   1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
# Line 18 | Line 280 | IBX Change Log  version
280     that BindFields is called when the query is next activated. Avoids FieldName
281     not found error.
282  
283 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
284 +   purpose and allows the programmer to define any action they want for Update, Insert
285 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
286 +   filtering of updates, or use of statements such as Grant or Revoke instead of
287 +   normal DML. See User Manual for more information.
288 +
289   IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
290  
291   1. TIBEvents: Fix uninitialised variable that could result in lost events.
