# Line 1 | Line 1
1 + IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
2 +
3 + 1.  TIBStringField: when a string value is read from a dataset buffer, if the
4 +    number of UTF8 characters exceeds the string size then string is truncated
5 +    to the maximum string size. This is  usually a problem with fixed width columns
6 +    right padded with white space.
7 +
8 + 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
9 +    If SQLFiltered is set then when a dataset is opened, each line in the
10 +    SQLFilterParams property is assumed to be a SQL condition clause and
11 +    ANDed into the Where clause of the SQL Select statement provided as a
12 +    dataset property. Each such SQL condition thus acts as an additional filter
13 +    on the dataset. (Not yet tested)
14 +
15 + 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
16 +    side filters).
17 +
18 + 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
19 +   text matches complete entry.
20 +
21 + 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
22 +   dataset are active (avoids risk of access violation if master is inactive)
23 +
24 + 6. TIBEvents: Registered property can now be set at design time even if database not open
25 +
26 + 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
27 +   This should prevent "spillover" of events between sessions.
28 +
29 + 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
30 +   This should ensure that the internal buffer is set up correctly and avoids
31 +   a duplicate initial row.
32 +
33 + 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
34 +   That is, the DataSize should be the field size * character set width. The
35 +   value returned by DataSize is now the same as the Dataset buffer size reserved
36 +   for the field.
37 +
38 + 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
39 +
40 + 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
41 +    and vice-versa. This may result in an exception being raised (correctly) for
42 +    older programs when using dataset fields added to a form and the database has been
43 +    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
44 +    In such cases, the field needs to be deleted in the IDE fields editor and then
45 +    added back in.
46 +
47 + 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
48 +    false if query contains white space and not just empty.
49 +
50 + 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
51 +    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
52 +    is cancelled.
53 +
54 + IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
55 +
56 + 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
57 +    not SQL Identifiers are now supported.
58 +
59 + 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
60 +    passed to the Firebird engine for execution.
61 +
62 + 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
63 +    is made to scroll back.
64 +
65 + 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
66 +
67 + 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
68 +   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
69 +
70 + 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
71 +   validated. If no match is found in the list of field names and the database has
72 +   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
73 +   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
74 +
75 + 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
76 +   with fpc 3.2.
77 +
78 + IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
79 +
80 +
81 + 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
82 +   and is used to override the default settings in the client side "firebird.conf" This
83 +   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
84 +   Each line of the string list should be a setting in the same format as "firebird.conf".
85 +   For example "WireCompression = true" in order to request wire compression on the client side.
86 +
87 +   Note: explicit settings in the client side "firebird.conf" appear to take precedence
88 +   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
89 +   also require a compatible setting in the server side "firebird.conf". For example
90 +   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
91 +   compression to be used.
92 +
93 +   Whether or not WireCompression or WireCrypt are in use can be checked using the information
94 +   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
95 +   ibx/examples/dbinfo for examples of how to display this information.
96 +
97 + 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
98 +   is a "convenience" property. If set the "WireCompression=true" is added to the
99 +   ConfigOverrides. If unchecked then this setting is removed.
100 +
101 + 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
102 +   not "INT64".
103 +
104 + 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
105 +   These are:
106 +    property TimestampFormat: string;
107 +    property DateFormat: string;
108 +    property TimeFormat: string;
109 +
110 +   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
111 +   DATETIME and TIME. The format strings use the standard FPC date/time format
112 +   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
113 +
114 +   If any of the above properties are set to an empty string, then the locale default
115 +   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
116 +   locale default is extended by appending '.zzz' to include milliseconds.
117 +
118 +   TIBCSVDataOut by default sets these properties to the empty string, while the other
119 +   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
120 +
121 + 5. New published property for TIBCSVDataOut:
122 +     property QuoteStrings: boolean (default true)
123 +
124 +   If false then strings are unquoted, otherwise, the QuoteChar property value is
125 +   used to delimit each and every string in the output.
126 +
127 + 6. New published properties for TIBCSVDataOut:
128 +    property FieldSeparator: string;
129 +    property HeaderSeparator: string;
130 +
131 +   Respectively, these provide the separator character(s) used to separate fields
132 +   in data and header rows. Both default to ','.
133 +
134 + 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
135 +    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
136 +    property OnFormatTextString;
137 +
138 +   This event handler can be used to process text strings before they are included
139 +   in the output e.g. to replace unprintable characters with alternative strings.
140 +   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
141 +
142 + 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
143 +   Uses "FindParam" if in order to find out if a parameter with a given name exists
144 +   and without raising and exception if it does not.
145 +
146 + 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
147 +   consistency with SQL queries.
148 +
149 + 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
150 +    When true, SQL statement parameter names are parsed case sensitive. Note for
151 +    TIBDataSet only applies to Select query.
152 +
153 + 11. IBEvents: removing a TIBEvent component from a form should no longer result in
154 +    an IDE exception.
155 +
156 + 12. LocalDBSupport: initial database creation should now work correctly
157 +    when the schema source is an sql file.
158 +
159 + 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
160 +    when defined, this handler will be called by the internal TIBXScript during
161 +    initial database creation when the schema source is an sql file and may be used
162 +    to provide a visual indication of progress in console mode.
163 +
164 + 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
165 +    to true while a new local database is being created and its schema populated.
166 +    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
167 +    when the database is disconnected/connected during the create DB procedure.
168 +
169 + 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
170 +    are now always ignored and replaced by the user name and password provided as
171 +    the login parameters for the TIBDatabase referenced from the TIBXScript. The
172 +    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
173 +    completely ignored if this property is true.
174 +
175 + 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
176 +    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
177 +    ImageIndex and SelectImageIndex values on AddNode.
178 +
179 + 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
180 +    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
181 +    the same database connection.
182 +
183 + 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
184 +    if provided, this should be an conditional SQL expression suitable for
185 +    including in an SQL Select statement "where" clause. If non-empty and the
186 +    "Filtered" property is true then the SQL expression provided as the value of
187 +    the "Filter" property is "ANDed" with any existing condition statement
188 +    in the SQL statement's "Where" clause.
189 +
190 +    If the "Filter" property is set at run time, the "Filtered" property is true
191 +    and the dataset is already open, then the dataset is closed and re-opened automatically.
192 +
193 +    The "Filter" condition may include IBX style parameters. In which case, their
194 +    value must be set by the dataset's "OnBeforeOpen" event handler.
195 +
196 +    This is a public property for TIBDataSet and TIBQuery query and intended for
197 +    use at run time.
198 +
199 +    Note: The property is a published property of TIBTable. The TIBTable functionality
200 +    is unaffected by this change.
201 +
202 + IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
203 +
204 + 1. Remove need to check for IsMultiThread by providing access to GUI timers via
205 +   IBGUIInterface. Note: master/detail delay timer does not apply to console
206 +   mode apps.
207 +
208 + 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
209 +   statement. This avoids problems if "Execute Block" is used as the Query.
210 +
211 + 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
212 +   internal SQL tokeniser routines.
213 +
214 + 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
215 +   as a select statement, with or without CTEs.
216 +
217 + 5. IBSQLParser: parser now recognises the "ROWS" clause.
218 +
219 + 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
220 +   internal SQL tokeniser routines.
221 +
222 + 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
223 +    being raised for valid set statements processed by a data formatter.
224 +
225 + 8. New published property for TIBDatabase and TIBXServicesConnection. This is
226 +   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
227 +   the path of the Firebird Library used by the database/services connection.
228 +
229 + 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
230 +   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
231 +   services connection.
232 +
233 + 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
234 +   or param name is not a valid SQL identifier.
235 +
236 + 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
237 +    view of whether the text box should be editable when no DataSource is specified.
238 +    TIBLookupComboEditBox has been updated to workaround this problem. As long as
239 +    ReadOnly is false, the text box is editable when no DataSource is specified.
240 +
241 + 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
242 +    the FBLIB environment variable. If you do not want to permit this then you
243 +    must modify the Register procedure in the design/IBDBReg.pas unit to remove
244 +    this setting.
245 +
246 + IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
247 +
248 + 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
249 +   Utf8EscapeControlChars
250 +
251   IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
