1 + IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
2 +
3 +
4 + 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
5 +   and is used to override the default settings in the client side "firebird.conf" This
6 +   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
7 +   Each line of the string list should be a setting in the same format as "firebird.conf".
8 +   For example "WireCompression = true" in order to request wire compression on the client side.
9 +
10 +   Note: explicit settings in the client side "firebird.conf" appear to take precedence
11 +   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
12 +   also require a compatible setting in the server side "firebird.conf". For example
13 +   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
14 +   compression to be used.
15 +
16 +   Whether or not WireCompression or WireCrypt are in use can be checked using the information
17 +   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
18 +   ibx/examples/dbinfo for examples of how to display this information.
19 +
20 + 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
21 +   is a "convenience" property. If set the "WireCompression=true" is added to the
22 +   ConfigOverrides. If unchecked then this setting is removed.
23 +
24 + 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
25 +   not "INT64".
26 +
27 + 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
28 +   These are:
29 +    property TimestampFormat: string;
30 +    property DateFormat: string;
31 +    property TimeFormat: string;
32 +
33 +   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
34 +   DATETIME and TIME. The format strings use the standard FPC date/time format
35 +   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
36 +
37 +   If any of the above properties are set to an empty string, then the locale default
38 +   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
39 +   locale default is extended by appending '.zzz' to include milliseconds.
40 +
41 +   TIBCSVDataOut by default sets these properties to the empty string, while the other
42 +   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
43 +
44 + 5. New published property for TIBCSVDataOut:
45 +     property QuoteStrings: boolean (default true)
46 +
47 +   If false then strings are unquoted, otherwise, the QuoteChar property value is
48 +   used to delimit each and every string in the output.
49 +
50 + 6. New published properties for TIBCSVDataOut:
51 +    property FieldSeparator: string;
52 +    property HeaderSeparator: string;
53 +
54 +   Respectively, these provide the separator character(s) used to separate fields
55 +   in data and header rows. Both default to ','.
56 +
57 + 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
58 +    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
59 +    property OnFormatTextString;
60 +
61 +   This event handler can be used to process text strings before they are included
62 +   in the output e.g. to replace unprintable characters with alternative strings.
63 +   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
64 +
65 + 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
66 +   Uses "FindParam" if in order to find out if a parameter with a given name exists
67 +   and without raising and exception if it does not.
68 +
69 + 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
70 +   consistency with SQL queries.
71 +
72 + 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
73 +    When true, SQL statement parameter names are parsed case sensitive. Note for
74 +    TIBDataSet only applies to Select query.
75 +
76 + 11. IBEvents: removing a TIBEvent component from a form should no longer result in
77 +    an IDE exception.
78 +
79 + 12. LocalDBSupport: initial database creation should now work correctly
80 +    when the schema source is an sql file.
81 +
82 + 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
83 +    when defined, this handler will be called by the internal TIBXScript during
84 +    initial database creation when the schema source is an sql file and may be used
85 +    to provide a visual indication of progress in console mode.
86 +
87 + 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
88 +    to true while a new local database is being created and its schema populated.
89 +    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
90 +    when the database is disconnected/connected during the create DB procedure.
91 +
92 + 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
93 +    are now always ignored and replaced by the user name and password provided as
94 +    the login parameters for the TIBDatabase referenced from the TIBXScript. The
95 +    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
96 +    completely ignored if this property is true.
97 +
98 + 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
99 +    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
100 +    ImageIndex and SelectImageIndex values on AddNode.
101 +
102 + 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
103 +    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
104 +    the same database connection.
105 +
106 + 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
107 +    if provided, this should be an conditional SQL expression suitable for
108 +    including in an SQL Select statement "where" clause. If non-empty and the
109 +    "Filtered" property is true then the SQL expression provided as the value of
110 +    the "Filter" property is "ANDed" with any existing condition statement
111 +    in the SQL statement's "Where" clause.
112 +
113 +    If the "Filter" property is set at run time, the "Filtered" property is true
114 +    and the dataset is already open, then the dataset is closed and re-opened automatically.
115 +
116 +    The "Filter" condition may include IBX style parameters. In which case, their
117 +    value must be set by the dataset's "OnBeforeOpen" event handler.
118 +
119 +    This is a public property for TIBDataSet and TIBQuery query and intended for
120 +    use at run time.
121 +
122 +    Note: The property is a published property of TIBTable. The TIBTable functionality
123 +    is unaffected by this change.
124 +
125 + IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
126 +
127 + 1. Remove need to check for IsMultiThread by providing access to GUI timers via
128 +   IBGUIInterface. Note: master/detail delay timer does not apply to console
129 +   mode apps.
130 +
131 + 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
132 +   statement. This avoids problems if "Execute Block" is used as the Query.
133 +
134 + 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
135 +   internal SQL tokeniser routines.
136 +
137 + 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
138 +   as a select statement, with or without CTEs.
139 +
140 + 5. IBSQLParser: parser now recognises the "ROWS" clause.
141 +
142 + 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
143 +   internal SQL tokeniser routines.
144 +
145 + 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
146 +    being raised for valid set statements processed by a data formatter.
147 +
148 + 8. New published property for TIBDatabase and TIBXServicesConnection. This is
149 +   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
150 +   the path of the Firebird Library used by the database/services connection.
151 +
152 + 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
153 +   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
154 +   services connection.
155 +
156 + 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
157 +   or param name is not a valid SQL identifier.
158 +
159 + 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
160 +    view of whether the text box should be editable when no DataSource is specified.
161 +    TIBLookupComboEditBox has been updated to workaround this problem. As long as
162 +    ReadOnly is false, the text box is editable when no DataSource is specified.
163 +
164 + 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
165 +    the FBLIB environment variable. If you do not want to permit this then you
166 +    must modify the Register procedure in the design/IBDBReg.pas unit to remove
167 +    this setting.
