1 + IBX Change Log  version                                              (2.2-0) Thu, 25 Jan 2018 13:56:39 +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. IBDatabase: 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.
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. FB3UserManager example added to illustrate use if IBX for managing user logins, passwords
96 +    and connections using IBX and with single or multiple security databases.
97 +
98 +
99 + IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
100 +
101 + 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
102 +   changes.
103 +
104 + 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
105 +   Bug could result in truncated multi-byte character set values.
106 +
107 + 3. Changes consequential on moving fbintf character set utility functions from
108 +   IFirebirdAPI to IAttachment.
109 +
110 + 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
111 +
112 + 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
113 +   results in autocomplete ignoring prefix text.
114 +
115 + 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
116 +   entering a new name into the text box.
117 +
118 + 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
119 +   Firebird rather than recomputing it.
120 +
121 + 8. Property Editor positioning tidy up: All IBX Property editors should now be
122 +   screen centre. Previously some were "poDesigned" which may be inappropriate
123 +   for multi monitor desktops.
124 +
125 + 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
126 +
127 + 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
128 +    a transaction and always reset the object.
129 +
130 + 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
131 +
132 + 13. TIBXScript: Allow for override of database filename in Create Database statements.
133 +
134 + 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
135 +    to a gbak format archive.
136 +
137 + 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
138 +
139 + 16. IBLocaldb: Drop database if error creating an empty database.
140 +
141 + 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
142 +    unless selected node not in current dataset.
143 +
144 + 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
145 +    to TIBCustomService, and IBlocalDB code tidy up.
146 +
147 + 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
148 +    behaviour due to uninitialised variable.
149 +
150 + 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
151 +    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
152 +
153 + 21. IBSQL: When Database changed ensure that all resources are freed.
154 +
155 + 22. IBCustomDataset: When database changed ensure that queries an unprepared.
156 +
157 + 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
158 +    * Line Wrap on SQL Token boundaries (on user command)
159 +    * auto-complete table names in drop down list of table names
160 +    * Double click on tablename or field name adds to SQL text
161 +
162 + 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
163 +
164 + 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
165 +    TVariantArray. Seems to avoid memory corruption in Windows (probably a
166 +    workaround for a problem in fpc 3.0.4 win64).
167 +
168 + 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
169 +
170 + 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
171 +
172 + IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
173 +
174 + 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
175 +   include remote system name.
176 +
177 + 2. TIBExtract: No longer include comment header and COMMIT statement for empty
178 +   tables when data included in output.
179 +
180 + 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
181 +   and timing information to be written to stdout. This may be used to locate
182 +   performance bottlenecks.
183 +
184 + 4. SQLParser: only call "OnChanging" event handler when value is different.
185 +
186 + 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
187 +
188 + 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
189 +   that BindFields is called when the query is next activated. Avoids FieldName
190 +   not found error.
191 +
192 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
193 +   purpose and allows the programmer to define any action they want for Update, Insert
194 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
195 +   filtering of updates, or use of statements such as Grant or Revoke instead of
196 +   normal DML. See User Manual for more information.
197 +
198 + IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
199 +
200 + 1. TIBEvents: Fix uninitialised variable that could result in lost events.
201 +
202 + 2. TIBExtract: Added support for FB3 "USAGE" privilege.
203 +
204 + 3. TIBExtract: data formatted as Charset set "octets" is now output using
205 +   hexadecimal notation.
206 +
207 + 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
208 +   using a simple XML format.
209 +
210 + 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
211 +   grants to these objects.
212 +
213 + 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
214 +   dependency problems restoring complex databases.
215 +
216 + 7. TIBXScript: This component has been restructured to allow for the processing of
217 +   embedded XML in INSERT statements and to support interactive sources in addition
218 +   to non-interactive data sources such as files.
219 +
220 + 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
221 +
222 + 9. TIBXScript: ISQL compatiable Set statements are now supported:
223 +   SET SQL DIALECT
224 +   SET TERM
225 +   SET AUTODDL
226 +   SET BAIL
227 +   SET ECHO
228 +   SET COUNT
229 +   SET STATS
230 +   SET NAMES <character set>
231 +
232 + 10. IBVersion unit added to hold current IBX Version Number information.
233 +
234 + 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
235 +    and domain definitions.
236 +
237 + 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
238 +    fully supported.
239 +
240 + 13. TIBExtract: when a database dump includes data, the generator values are now also set.
241 +
242 + 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
243 +
244 + IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
245 +
246 + See also doc/IBX4LazarusGuide.pdf for important information on
247 + upgrading to IBX2.
248 +
249 + 1. Size property of TIBStringField is now the width in characters of the field
250 +   and not the byte length. This applies only to multi-byte character sets such
251 +   as UTF8. The original approach aligned with TStringField. However, the TStringField
252 +   code is not recognised as a bug and hence this change to align the behaviour.
253 +   The TStringField change is expected in fpc 3.2.0.
254 +
255 + 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
256 +   true (default) then Size property value saved in the lfm is ignored. Size is
257 +   always set from the dynamic information read from the database. It is unclear
258 +   why anyone would want to override this and set Size to false.
259 +
260 + 3. ibxscript: should now handle correctly a Case..End statement within a procedure
261 +   block.
262 +
263 + 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
264 +   exist when an attempt is made to connect to it (run time only) then an attempt
265 +   is made to create the database.
266 +
267 + 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
268 +   has been successfully created as a result of a call to CreateDatabase or when
269 +   creating a database after it was found not to exist.
270 +
271 + 6.  DBControlGrid: a race condition could result in the wrong row image being
272 +    written to the cache. This has been avoided by a trip round the message
273 +    loop before rendering the row image.
274 +
275 + 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
276 +    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
277 +    known to risk corrupt rendering of row images when the control is first
278 +    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
279 +    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
280 +
281 + 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
282 +    a TDateEdit control located on an editor panel.
283 +
284 + 9.  TIBExtract: brought up-to-date plus many bug fixes.
285 +
286 + 10. DBControlGrid: Removed memory leak when updating rows.
287 +
288 + 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
289 +

313   1. IBBlob: Defer reading of blob until read method called. This avoids having to
314     read in an entire blob just to get the size of the blob. General performance
