1 + IBX Change Log  version                           (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
2 +
3 + 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
4 +   changes.
5 +
6 + 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
7 +   Bug could result in truncated multi-byte character set values.
8 +
9 + 3. Changes consequential on moving fbintf character set utility functions from
10 +   IFirebirdAPI to IAttachment.
11 +
12 + 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
13 +
14 + 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
15 +   results in autocomplete ignoring prefix text.
16 +
17 + 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
18 +   entering a new name into the text box.
19 +
20 + 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
21 +   Firebird rather than recomputing it.
22 +
23 + 8. Property Editor positioning tidy up: All IBX Property editors should now be
24 +   screen centre. Previously some were "poDesigned" which may be inappropriate
25 +   for multi monitor desktops.
26 +
27 + 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
28 +
29 + 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
30 +    a transaction and always reset the object.
31 +
32 + 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
33 +
34 + 13. TIBXScript: Allow for override of database filename in Create Database statements.
35 +
36 + 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
37 +    to a gbak format archive.
38 +
39 + 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
40 +
41 + 16. IBLocaldb: Drop database if error creating an empty database.
42 +
43 + 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
44 +    unless selected node not in current dataset.
45 +
46 + 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
47 +    to TIBCustomService, and IBlocalDB code tidy up.
48 +
49 + 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
50 +    behaviour due to uninitialised variable.
51 +
52 + 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
53 +    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
54 +
55 + 21. IBSQL: When Database changed ensure that all resources are freed.
56 +
57 + 22. IBCustomDataset: When database changed ensure that queries an unprepared.
58 +
59 + 23. SQL Property Editors now use SynEdit with SQL Highlighter.
60 +
61 + 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
62 +
63 + 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
64 +    TVariantArray. Seems to avoid memory corruption in Windows (probably a
65 +    workaround for a problem in fpc 3.0.4 win64).
66 +
67 + 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
68 +
69 + 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
70 +
71 + IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
72 +
73 + 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
74 +   include remote system name.
75 +
76 + 2. TIBExtract: No longer include comment header and COMMIT statement for empty
77 +   tables when data included in output.
78 +
79 + 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
80 +   and timing information to be written to stdout. This may be used to locate
81 +   performance bottlenecks.
82 +
83 + 4. SQLParser: only call "OnChanging" event handler when value is different.
84 +
85 + 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
86 +
87 + 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
88 +   that BindFields is called when the query is next activated. Avoids FieldName
89 +   not found error.
90 +
91 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
92 +   purpose and allows the programmer to define any action they want for Update, Insert
93 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
94 +   filtering of updates, or use of statements such as Grant or Revoke instead of
95 +   normal DML. See User Manual for more information.
96 +
97 + IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
98 +
99 + 1. TIBEvents: Fix uninitialised variable that could result in lost events.
100 +
101 + 2. TIBExtract: Added support for FB3 "USAGE" privilege.
102 +
103 + 3. TIBExtract: data formatted as Charset set "octets" is now output using
104 +   hexadecimal notation.
105 +
106 + 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
107 +   using a simple XML format.
108 +
109 + 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
110 +   grants to these objects.
111 +
112 + 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
113 +   dependency problems restoring complex databases.
114 +
115 + 7. TIBXScript: This component has been restructured to allow for the processing of
116 +   embedded XML in INSERT statements and to support interactive sources in addition
117 +   to non-interactive data sources such as files.
118 +
119 + 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
120 +
121 + 9. TIBXScript: ISQL compatiable Set statements are now supported:
122 +   SET SQL DIALECT
123 +   SET TERM
124 +   SET AUTODDL
125 +   SET BAIL
126 +   SET ECHO
127 +   SET COUNT
128 +   SET STATS
129 +   SET NAMES <character set>
130 +
131 + 10. IBVersion unit added to hold current IBX Version Number information.
132 +
133 + 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
134 +    and domain definitions.
135 +
136 + 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
137 +    fully supported.
138 +
139 + 13. TIBExtract: when a database dump includes data, the generator values are now also set.
140 +
141 + 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
142 +
143 + IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
144 +
145 + See also doc/IBX4LazarusGuide.pdf for important information on
146 + upgrading to IBX2.
147 +
148 + 1. Size property of TIBStringField is now the width in characters of the field
149 +   and not the byte length. This applies only to multi-byte character sets such
150 +   as UTF8. The original approach aligned with TStringField. However, the TStringField
151 +   code is not recognised as a bug and hence this change to align the behaviour.
152 +   The TStringField change is expected in fpc 3.2.0.
153 +
154 + 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
155 +   true (default) then Size property value saved in the lfm is ignored. Size is
156 +   always set from the dynamic information read from the database. It is unclear
157 +   why anyone would want to override this and set Size to false.
158 +
159 + 3. ibxscript: should now handle correctly a Case..End statement within a procedure
160 +   block.
161 +
162 + 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
163 +   exist when an attempt is made to connect to it (run time only) then an attempt
164 +   is made to create the database.
165 +
166 + 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
167 +   has been successfully created as a result of a call to CreateDatabase or when
168 +   creating a database after it was found not to exist.
169 +
170 + 6.  DBControlGrid: a race condition could result in the wrong row image being
171 +    written to the cache. This has been avoided by a trip round the message
172 +    loop before rendering the row image.
173 +
174 + 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
175 +    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
176 +    known to risk corrupt rendering of row images when the control is first
177 +    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
178 +    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
179 +
180 + 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
181 +    a TDateEdit control located on an editor panel.
182 +
183 + 9.  TIBExtract: brought up-to-date plus many bug fixes.
184 +
185 + 10. DBControlGrid: Removed memory leak when updating rows.
186 +
187 + 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
188 +
189 + IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
190 +
191 + 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
192 +   when target codepage is CP_NONE. This is a workaround for
193 +   http://bugs.freepascal.org/view.php?id=30622.
194 +
195 + 2. DBLog option removed from TIBStatisticalService - not supported by server
196 +   since Firebird 1.5.
197 +
198 + 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
199 +   similar.
200 +
201 + 4. IBCodePage: updated mapping between codepages and character id.
202 +
203 + 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
204 +   Firebird. Character sets with a char width of two are not UTF16.
205 +
206 + 6. Strings received from the database are now always transliterated into UTF8
207 +   regardless of the database character set or connection character set. This
208 +   is for compatibility with the LCL.
209 +
210 + IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
211 +
212 + 1. IBBlob: Defer reading of blob until read method called. This avoids having to
213 +   read in an entire blob just to get the size of the blob. General performance
214 +   improvement when opening datasets containing blobs.
215 +
216 + 2. Clearing a  Blob now sets the corresponding field's modified flag.
217 +
218 + 3. IBLookupCombo: When not performing auto-complete, original query sort order
219 +   is now used.
220 +
221 + 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
222 +   determined.
223 +
224 + 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
225 +
226 + 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
227 +   lazarus 1.6.0
228 +
229 + 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
230 +   compilation error.
231 +
232 + IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
233 +
234 + 1. No character set specified for connection: when a text blob is retrieved, the
235 +  character set is determined by looking up the native character set using then
236 +  Firebird API. Otherwise a text mode blob is assumed to have the same character
237 +  set as the connection.
238 +
239 + 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
240 +   for Login Dialog returing a change to the database path.
241 +
242 + 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
243 +   to be changed from that given in the TIBDatabase/TIBServer component and for the
244 +   entered value to be saved on a project specific basis (design time only).
245 +
246 + 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
247 +   column fieldname. If they are the same then it is acts as a look up for the KeyValue
248 +   Otherwise, it sets the column text to the selected ListField Value.
249 +
250 + 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
251 +   column width.
252 +
253 + 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
254 +   and a case insensitive search is requested.
255 +
256 + 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
257 +   or column ListSource.
258 +
259 + 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
260 +   unprepare) when closing and the text has not changed.
261 +
262 + 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
263 +   Less likely to cause a cursor re-use error on Windows.
264 +
265 + 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
266 +   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
267 +
268 + 11. TIBTreeView: Guard against nil destination on record changed
269 +
270 + 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
271 +    string type with the code page set to reflect the returned field encoding after
272 +    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
273 +    earlier versions.
274 +
275 + 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
276 +    will now result in transliteration to the code page specified for the Firebird driver
277 +    if the assigned string has a different code page. FPC 3.0.0 onwards only.
278 +
279 + 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
280 +    is ignored and the lc_ctype value, when the database is opened, is set to align with
281 +    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
282 +    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
283 +    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
284 +    the GETACP is used to determine the Windows code page.
285 +
286 + 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
287 +    name used as the lc_ctype when the database was opened. Only valid while the
288 +    Database is connected.
289 +
290 + 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
291 +    id that corresponds to the DefaultCharSetName.
292 +
