1 < FBINTF Change Log  version          (1.1-6 Build 12214) Fri, 17 Jul 2020 23:10:11 +0100
1 > IBX Change Log  version (2.4-3 Build 12803) Wed, 06 Oct 2021 10:20:04 +0100
2  
3 < 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
4 <   with a Firebrid 3 client library.
3 > 1. Add try-..except check when initially loading library in IDE. This should
4 > ensure that IDE continues to load even when a failure occurs in IBX load
5 > library.
6  
7 < 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
8 <    If a client library path is not explicitly provided and the FIREBIRD environment
9 <    variable is set then the directory given by this variable and any 'lib' subdirectory
9 <    are searched for the Firebird client library. Only if none is found, is the default
10 <    client library used.
7 > 2. IBXScript: now recognises a CASE...END block within a stored procedure and
8 >   hence will correctly detect end of the outer containing block when the block
9 >   contains a SELECT ... CASE ... END construct.
10  
11 < 3.  IUtil.FormatStatus now used to format error messages when using new API
11 > 3. IBExtract: some further tidying up to remove extraneous white space.
12  
13 < 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
13 > IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
14  
15 < 5.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
16 <    returned using GetAsString and the string codepage is UTF8, the string is truncated so
18 <    that the byte length corresponds to the number of characters specified for the column.
19 <    SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
20 <    correct behaviour but may affect some implementations that relied upon automatic
21 <    trimming of trailing white space.
15 > 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
16 >   exception of those defined to be one byte wide e.g. DBImplementationNo.
17  
18 < 6.  New IFirebirdAPI Calls:
24 <      function GetClientMajor: integer;
25 <      function GetClientMinor: integer;
18 > 2. TIBSQL: Batch Update/Insert support added.
19  
20 + 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
21 +   is no longer automatically converted to upper case when it is syntactically a
22 +   SQL Identifier. This is to support the use of stored procedures defined e.g.
23 +   as CREATE PROCEDURE "iCASE".
24  
25 < FBINTF Change Log  version          (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +0100
25 >   There could be a backwards compatibility issue when the StoredProcName was entered
26 >   manually at design time. That is not selected from the drop down list. If the
27 >   StoredProcName is entered in mixed case and the procedure was declared e.g. as
28 >   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
29 >   ensure that the value of the StoredProcName is all upper case, unless it was
30 >   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
31 >   quotes).
32  
33 < 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
34 <   case sensitive
33 >   Note that when a stored procedure name was declared delimited in double quotes,
34 >   as in the first example above, the value of the StoredProcName property must not
35 >   include the delimiters (double quotes).
36  
37 < 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
37 > 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
38 >   upgrade.conf was not found. This replaces silently ignoring the problem.
39  
40 < 3. New API Calls:
41 <        IColumnMetaData.GetStatement
42 <        IColumnMetaData.GetTransaction
38 <        ISQLData.GetStrLength
39 <        IResults.GetStatement
40 <        IAttachment.OpenBlob (using Blob metadata)
41 <        IAttachment.OpenArray (using array metadata)
40 > 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
41 >   'Version.%.3d' and is used to generate the section header names (for a given
42 >   version no.) in the upgrade.conf file.
43  
44 < 4. FBMessages: removal of unused messages
44 > IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
45  
46 < 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
46 > 1. -c command line option added to fbsql example program. Used to set connection
47 >   character set.
48  
49 < 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
49 > IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
50  
51 < FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
51 > 1. Firebird 4 support added.
52  
53 < 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
54 <   where the second character of the parameter name is a numeric.
53 > 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
54 >   extended precision NUMERIC fields are supported.
55  
56 < 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
55 <   This returns the isc_version connection information as one or more lines.
56 <   This is the same information as returned by isql with the -z option.
56 > 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
57  
58 < 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
59 <   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
60 <   compiler option then the Firebird 3 API is no longer compiled in.
58 > 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
59 >   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
60  
61 < 4. IColumnMetaData: new method.
61 > 5. IBExtract now supports FB4 enhancements:
62 >   - new data types as above
63 >   - Identity column extensions
64 >   - Default user role
65 >   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
66 >   - Internal Functions
67  
68 <   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
65 <                        dfDateTime,   {SQL DATETIME}
66 <                        dfTime);
68 > 6. IBExtract: new event: OnExtractLines.
69  
70 <   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
70 > 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
71  
72 <   This returns the max. number of characters returned by the "AsString" method
73 <   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
72 > 8. IBXServices: Server version no. parsing now allows any letter before major version number
73 >   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
74  
75 < 5. Additional argument for IAttachment.PrepareWithNamedParameters -
76 <     CaseSensitiveParams: boolean = false
75 > 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
76 >   format for rendering a time zone.
77  
78 <   If this argument is set to true then SQL parameter names are assumed to be case
79 <   sensitive and must be referenced (using ISQLParams.ByName) using the case
78 <   sensitive name.
78 > 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
79 >     to convert TIME WITH TIME ZONE data type values to and from GMT.
80  
81 < 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
82 <   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
82 <   .AsCurrency) and then subsequently to update the value to a non-numeric string
83 <   using .AsString.
81 > 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
82 >    IIBGUIInterface and IIBTimerInf respectively.
83  
84 + 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
85 +    now accessible as properties of TIBDatabase and TIBTransaction respectively.
86  
87 + 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
88 +    truncated to its fixed character width rather than being right padded with
89 +    white space to the maximum data size.
90  
91 < FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
91 > 14. TIBTable.Empty table. In additional to deleting all records in the underlying
92 >    table, the internal buffers are now also flushed ensuring that the TIBTable is
93 >    also empty.
94  
95 < 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
95 > 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
96  
97 < 2. Restrict IsMultiThread check to Unix only for compatibility with
98 <   https://bugs.freepascal.org/view.php?id=30535
97 > 16. TIBXControlService descendents: DatabaseName may now be set using a database
98 >    connect string. The database name is extracted from the connect string.
99  
100 < 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
95 <   named parameters and is intended to avoid problems with (e.g.) Execute Block
96 <   and processing internal parameters as statement parameters.
100 > 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
101  
102 < 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
99 <   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
102 > 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
103  
104 < 5. New function added to IB.pas
104 > 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
105 >    not being present as required.
106  
107 <   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
107 > 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
108 >    version that can be customised to work with other database drivers.
109  
110 <   This allows a Firebird Library to be loaded from an explicit path. use the
111 <   IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
107 <   the library. It is possible to load Firebird libraries from different locations
108 <   simultaneously, each with a distinct IFirebirdAPI.
110 > 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
111 >    unnecessary CR at end of line on Unix platforms.
112  
113 < FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
113 > 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
114 >    seconds in order to reduce risk of message loss.
115  
116 < 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
117 <   program compiled with -CR command line switch.
116 > 23. ISQLMonitor: read and write count statistics now available via:
117 >      property TIBSQLMonitor.ReadCount;
118 >      IIBSQLMonitorHook.GetWriteCount: integer;
119  
120 < 2. IServiceManager additions (informational):
116 <    function getProtocol: TProtocol;
117 <    function getPortNo: AnsiString;
120 > 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
121  
122 < 3. IServiceManager improved error handling. Interfaces changed:
120 <    function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
121 <    function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
122 <    function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
122 > IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
123  
124 < 4. IAttachment addition (informational)
125 <    function GetSecurityDatabase: AnsiString;
124 > 1.  TIBStringField: when a string value is read from a dataset buffer, if the
125 >    number of UTF8 characters exceeds the string size then string is truncated
126 >    to the maximum string size. This is  usually a problem with fixed width columns
127 >    right padded with white space.
128  
129 < 5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
130 <   thus now returns accumulated stats for a select statement from opening a cursor
131 <   up to the last fetch.
129 > 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
130 >    If SQLFiltered is set then when a dataset is opened, each line in the
131 >    SQLFilterParams property is assumed to be a SQL condition clause and
132 >    ANDed into the Where clause of the SQL Select statement provided as a
133 >    dataset property. Each such SQL condition thus acts as an additional filter
134 >    on the dataset.
135  
136 < 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
137 <   the problem.
136 > 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
137 >    side filters).
138  
139 < 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
140 <   replaces deprecated "comp" type.
139 > 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
140 >   text matches complete entry.
141  
142 < 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
142 > 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
143 >   dataset are active (avoids risk of access violation if master is inactive)
144  
145 < 11. URL Connection Strings: inet4 and inet6 now recognised.
145 > 6. TIBEvents: Registered property can now be set at design time even if database not open
146  
147 < 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
147 > 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
148 >   This should prevent "spillover" of events between sessions.
149  
150 < 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
150 > 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
151 >   This should ensure that the internal buffer is set up correctly and avoids
152 >   a duplicate initial row.
153  
154 + 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
155 +   That is, the DataSize should be the field size * character set width. The
156 +   value returned by DataSize is now the same as the Dataset buffer size reserved
157 +   for the field.
158  
159 < FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
159 > 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
160  
161 < 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
161 > 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
162 >    and vice-versa. This may result in an exception being raised (correctly) for
163 >    older programs when using dataset fields added to a form and the database has been
164 >    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
165 >    In such cases, the field needs to be deleted in the IDE fields editor and then
166 >    added back in.
167  
168 < 2. IAttachment: add two new methods
169 <     function HasDefaultCharSet: boolean;
152 <     function GetDefaultCharSetID: integer;
168 > 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
169 >    false if query contains only white space and not just empty.
170  
171 <   These return, respectively, true if a connection default character set was
172 <   specified and the character set id of the connection default character set.
173 <   The DefaultCharSetID is cached when the connection is opened and hence does not
157 <   require a database lookup.
171 > 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
172 >    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
173 >    is cancelled.
174  
175 < 3. Avoid exception when a text blob is a stored procedure parameter.
175 > 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
176 >    called on a null field.
177  
178 < 4. Update test suite to include a test for a stored proc returning a text blob.
178 > 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
179 >    results in an empty dataTC86                Client side Filtered Dataset    1       X
180 > set.
181  
182 < 5. IAttachment: add
183 <      function GetRemoteProtocol: AnsiString;
165 <      function GetODSMajorVersion: integer;
166 <      function GetODSMinorVersion: integer;
167 <      function GetAuthenticationMethod: AnsiString;
182 > 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
183 >    a cached update is applied and an exception is raised.
184  
185 <   These results are cached when the connection is opened and hence do not
170 <   require a database lookup.
185 > 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
186  
187 < 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
173 <   connect string used to create/connect to the database.
187 > 17. Console Mode Local Database support: backup/restore should now work correctly.
188  
189 < 7. IAttachment: Create Database using SQL statement. The username and password
190 <   are now extracted and used to populate a DPB made available via IAttachment.getDPB.
177 <   It is now possible to use IAttachment disconnect/connect to reconnect to
178 <   a database for which the initial connection was established by a create
179 <   database sql statement. Available in FPC only.
189 > 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
190 >    possible and an exception raised.
191  
192 < 8. Update Test 1 to test 5, 6 and 7 above.
192 > 19. MinimumVersionNo added to Local Database Support. Database will not open if
193 >    below this version no. and upgrade not possible.
194  
195 < 9. IBUtils code tidy up.
195 > IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
196  
197 < 10. Parameter Block interfaces "find" method. As documented, this should have
198 <   returned a nil interface when the item could not be found. Instead, an empty
187 <   interface item was returned. "Find" now works as documented and will return
188 <   a nil interface if the item cannot be found.
197 > 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
198 >    not SQL Identifiers are now supported.
199  
200 < 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
200 > 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
201 >    passed to the Firebird engine for execution.
202  
203 < 12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
204 <    requests with additional parameters. This is to enable support for fb_info_page_contents
194 <    (return of page contents). Response to fb_info_page_contents returned as
195 <    a string with code page CP_NONE.
203 > 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
204 >    is made to scroll back.
205  
206 < 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
198 <    test suite updated.
206 > 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
207  
208 < 14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
209 <    a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
208 > 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
209 >   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
210  
211 < 15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
212 <    An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
213 <    default connection port to be specified.
211 > 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
212 >   validated. If no match is found in the list of field names and the database has
213 >   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
214 >   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
215  
216 < FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
216 > 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
217 >   with fpc 3.2.
218  
219 < 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
210 <   Scale is no longer ignored.
219 > IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
220  
212 2. Fix issues with setting SQL Param values using SetAsString with Date values
213   not in locale format but which are recognised by Firebird. Date values that
214   cannot be converted to a string using Pascal library are now passed through
215   to Firebird as Text Strings.
221  
222 < 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
223 <   UTF8 and not UNICODE_FSS.
222 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
223 >   and is used to override the default settings in the client side "firebird.conf" This
224 >   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
225 >   Each line of the string list should be a setting in the same format as "firebird.conf".
226 >   For example "WireCompression = true" in order to request wire compression on the client side.
227  
228 < 4. Charset ID problem. When using Firebird 3, with no default database character set
229 <   and a column has a non-default collation specified, an incorrect character set
230 <   id was being reported that could result in a 'division by zero' error when
231 <   used by IBX. This has now been fixed.
228 >   Note: explicit settings in the client side "firebird.conf" appear to take precedence
229 >   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
230 >   also require a compatible setting in the server side "firebird.conf". For example
231 >   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
232 >   compression to be used.
233  
234 < 5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
235 <   CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
236 <   the character sets supported can be updated on a per database basis. That is
228 <   it is possible to add a (Firebird) user defined character set to a database.
234 >   Whether or not WireCompression or WireCrypt are in use can be checked using the information
235 >   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
236 >   ibx/examples/dbinfo for examples of how to display this information.
237  
238 < 6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
239 <   set supported by Firebird with the API.
238 > 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
239 >   is a "convenience" property. If set the "WireCompression=true" is added to the
240 >   ConfigOverrides. If unchecked then this setting is removed.
241  
242 < 7. Add missing isc_info_db_read_only to list of decoded Database Information items
243 <   in FBOutputBlock.pas and update test suite to include this item.
242 > 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
243 >   not "INT64".
244  
245 < 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
245 > 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
246 >   These are:
247 >    property TimestampFormat: string;
248 >    property DateFormat: string;
249 >    property TimeFormat: string;
250  
251 < 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
252 <   library or finding it by disk location, the PATH environment variable is now also set to
253 <   include the FIREBIRD directory. This is to ensure that the correct dlls in the
241 <   firebird client library dependencies are loaded.
251 >   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
252 >   DATETIME and TIME. The format strings use the standard FPC date/time format
253 >   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
254  
255 < 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
255 >   If any of the above properties are set to an empty string, then the locale default
256 >   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
257 >   locale default is extended by appending '.zzz' to include milliseconds.
258  
259 < 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
259 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
260 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
261  
262 < 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
262 > 5. New published property for TIBCSVDataOut:
263 >     property QuoteStrings: boolean (default true)
264  
265 < 13. FB30Statement: A check has been added to ensure that all SQL Parameters
266 <    have been given a value (including NULL). Previously, failing to set the
251 <    value of an SQL Parameter could give rise to unpredictable results or
252 <    an SQLDA error.
265 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
266 >   used to delimit each and every string in the output.
267  
268 < 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
268 > 6. New published properties for TIBCSVDataOut:
269 >    property FieldSeparator: string;
270 >    property HeaderSeparator: string;
271  
272 < 15. FBAttachment: Avoid string reference count error when processing an Ansistring
273 <    parameter in an array of const passed to IAttachment.OpenCursor, etc.
272 >   Respectively, these provide the separator character(s) used to separate fields
273 >   in data and header rows. Both default to ','.
274  
275 < 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
276 <    of const passed to IAttachment.OpenCursor, etc.
275 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
276 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
277 >    property OnFormatTextString;
278  
279 +   This event handler can be used to process text strings before they are included
280 +   in the output e.g. to replace unprintable characters with alternative strings.
281 +   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
282  
283 < FBINTF Change Log  version             (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
283 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
284 >   Uses "FindParam" if in order to find out if a parameter with a given name exists
285 >   and without raising and exception if it does not.
286  
287 < 1. Change syntax to Mode Delphi
287 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
288 >   consistency with SQL queries.
289  
290 < 2. Change all uses of string type to explicit AnsiString in order to ensure
291 <   compatibility between Delphi and FPC.
290 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
291 >    When true, SQL statement parameter names are parsed case sensitive. Note for
292 >    TIBDataSet only applies to Select query.
293  
294 < 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
295 <   defined for each interface.
294 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
295 >    an IDE exception.
296  
297 < 4. Generics syntax variations for Delphi added
297 > 12. LocalDBSupport: initial database creation should now work correctly
298 >    when the schema source is an sql file.
299  
300 < 5. PChar replaced with PByte expect where an actual string is being referenced,
301 <   where PAnsiChar is used instead.
300 > 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
301 >    when defined, this handler will be called by the internal TIBXScript during
302 >    initial database creation when the schema source is an sql file and may be used
303 >    to provide a visual indication of progress in console mode.
304  
305 < 6. Review of type definitions in IBExternals to ensure Delphi compatibility
305 > 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
306 >    to true while a new local database is being created and its schema populated.
307 >    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
308 >    when the database is disconnected/connected during the create DB procedure.
309  
310 < 7. Testsuite updated for Delphi
310 > 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
311 >    are now always ignored and replaced by the user name and password provided as
312 >    the login parameters for the TIBDatabase referenced from the TIBXScript. The
313 >    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
314 >    completely ignored if this property is true.
315  
316 < FBINTF Change Log  version            (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
316 > 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
317 >    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
318 >    ImageIndex and SelectImageIndex values on AddNode.
319  
320 < 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
321 <   large blobs and the FB3 API.
320 > 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
321 >    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
322 >    the same database connection.
323  
324 < 2. Update Event Handling algorithm to avoid looping due to recreation of the
325 <   event block.
324 > 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
325 >    if provided, this should be an conditional SQL expression suitable for
326 >    including in an SQL Select statement "where" clause. If non-empty and the
327 >    "Filtered" property is true then the SQL expression provided as the value of
328 >    the "Filter" property is "ANDed" with any existing condition statement
329 >    in the SQL statement's "Where" clause.
330  
331 < 3. Avoid invalid XSQLDA error when the only parameter is updated to null
331 >    If the "Filter" property is set at run time, the "Filtered" property is true
332 >    and the dataset is already open, then the dataset is closed and re-opened automatically.
333  
334 < 4. Array Handling: fix problem with text arrays with character set none. When the
335 <   DB connection has a default character set (e.g. UTF8), an error is raised by
294 <   Firebird if the space allocated is not enough to allow for transliteration, even
295 <   though it is not required for character set none.
334 >    The "Filter" condition may include IBX style parameters. In which case, their
335 >    value must be set by the dataset's "OnBeforeOpen" event handler.
336  
337 < 5. IBUtils: List of reserved words brought up-to-date
337 >    This is a public property for TIBDataSet and TIBQuery query and intended for
338 >    use at run time.
339  
340 < 6. Add ISQL style performance statistics collection to IStatement
340 >    Note: The property is a published property of TIBTable. The TIBTable functionality
341 >    is unaffected by this change.
342  
343 < 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
302 <   CREATE DATABASE statement.
343 > IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
344  
345 < 8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in
346 <   an array dimension is not mistaken for a named parameter prefix.
345 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
346 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
347 >   mode apps.
348  
349 < 9. Trim function no longer applied to result of GetAsString for SQL_TEXT
350 <   when Character set is octets. Avoids loss of non printable characters at start of string.
349 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
350 >   statement. This avoids problems if "Execute Block" is used as the Query.
351  
352 < 10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
353 <    statistics for the last action. Requires use of procedure IStatement.EnableStatistics
312 <    to enable stats gathering.
352 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
353 >   internal SQL tokeniser routines.
354  
355 < 11. API Version information added as constants to IB.pas
355 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
356 >   as a select statement, with or without CTEs.
357  
358 < 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
358 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
359  
360 < 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
360 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
361 >   internal SQL tokeniser routines.

363 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
364 >    being raised for valid set statements processed by a data formatter.
365  
366 < 1. Initial Release
366 > 8. New published property for TIBDatabase and TIBXServicesConnection. This is
367 >   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
368 >   the path of the Firebird Library used by the database/services connection.
369  
370 + 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
371 +   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
372 +   services connection.
373 +
374 + 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
375 +   or param name is not a valid SQL identifier.
376 +
377 + 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
378 +    view of whether the text box should be editable when no DataSource is specified.
379 +    TIBLookupComboEditBox has been updated to workaround this problem. As long as
380 +    ReadOnly is false, the text box is editable when no DataSource is specified.
381 +
382 + 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
383 +    the FBLIB environment variable. If you do not want to permit this then you
384 +    must modify the Register procedure in the design/IBDBReg.pas unit to remove
385 +    this setting.

392 + IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
393 +
394 + IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
395 + all previous copies of the IBX source code tree before installing this release.
396 +
397 + The IBX packages used by most users have not changed, with one exception. The
398 + IBServices unit has been moved to the package iblegacyServices.lpk. To continue
399 + to use the IBServices unit in your applications, please add the iblegacyServices
400 + to the list of dependencies. To do this, open the Project Inspector and select
401 + Add->New Requirement and select "ibLegacyServices" from the list of available
402 + packages.
403 +
404 + 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
405 +   the IBServices unit providing what is intended to be a clearer and easier to
406 +   use set of IB Services components. See Chapter 10 of the IBX User Guide for
407 +   more information and the guide to "Firebird Service Management Using IBX".
408 +   As indicated above, the legacy services components are still available and
409 +   provided in a separate package. There is no need to update working applications
410 +   using the older versions except for an additional package dependency.
411 +
412 + 2. The IBX packages and source code tree have been re-organised in an attempt to
413 +   finally get rid of the "duplicate ppu" warnings. This re-organisation should
414 +   not affect existing users. Section 2.3 of the IBX User Guide describes the
415 +   new set of IBX packages.
416 +
417 + 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
418 +   updated to use the new Services API components.
419 +
420 + 4. The iblocal package has been updated to use the new Services API components.
421 +
422 + 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
423 +   TIBXSecurityService. It had been wrongly classified in the previous version
424 +   as a per database configuration item. It is global to a server and hence
425 +   correctly positioned as part of the Security Package. In the DBAdmin example,
426 +   the setting has moved to the mappings page.
427 +
428 + 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
429 +   are ignored.
430 +
431 + 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
432 +   closed before the database is dropped. Before and After Disconnect event handlers
433 +   are also fired.
434 +
435 + 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
436 +   is started and not just the first time.
437 +
438 + 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
439 +   depenendency with comp type.
440 +
441 + 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
442 +
443 + 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
444 +    then this is recognised and not ignored.
445 +
446 + 12. TIBDataSet, TIBQuery, TIBTable: additions:
447 +    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
448 +    function GetPerfStatistics(var stats: TPerfCounters): boolean;
449 +    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
450 +
451 +    GetRowsAffected returns the affected row counts from the last insert/update/delete
452 +    if EnableStatistics = true then GetPerfStatistics returns the current stats
453 +    counters for the select query. Note: stats accumulate after each fetch from
454 +    the database. To get total query cost after open, call the "Last" method
455 +    and then GetPerfStatistics.
456 +
457 +    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
458 +
459 + 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
460 +    in parenthesises.
461 +
462 + 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
463 +    SQL identifiers are always delimited by double quotes. If false, then they are
464 +    only delimited if the identifier is a reserved word, contains lower case or special
465 +    characters. Set this property to true to retain previous behaviour.
466 +
467 + 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
468 +    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
469 +
470 + 16. TIBDataSet, TIBQuery, TIBTable: addition:
471 +       property MasterDetailDelay: integer {defaults to zero}
472 +
473 +    When non-zero and the dataset is a detail table referencing a master table
474 +    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
475 +    then a synchronisation delay is added (in milliseconds) between the master
476 +    row changing and the detail dataset being re-opened. If the master dataset
477 +    is scrolled before the delay expires then the delay is reset. This can be used
478 +    to avoid performance overheads when scrolling through a large master dataset.
479 +
480 +    Note: uses fptimer and hence requires a thread manager. Under Linux the
481 +    chreads unit must be included in your project. TTimer is not used in order
482 +    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
483 +
484 + 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
485 +    with Extract Option eoDatabase.
486 +
487 + 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
488 +    When a deLayoutChanged event is reported on the ListSource dataset, the
489 +    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
490 +    relationship with the control's datasource (master).
491 +
492 + 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
493 +
494 + 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
495 +    stubs. Pedantic fix really, as procedures output in dependency order anyway.
496 +
497 + 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
498 +    DDL (Firebird 3 and later only).
499 +
500 + 22. TIBLookupComboBox Autocomplete Fixes:
501 +    i. Only appended text is now selected after autocomplete.
502 +    ii. Uppercase keys no longer ignored for autocomplete.
503 +    iii. Retain Prefix case is now honoured correctly.
504 +    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
505 +        before autocomplete performed. i.e. behaviour now the same as when
506 +        no DataSource assigned.
507 +
508 + 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
509 +    between SQL statements.
510 +
511 + 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
512 +    ObjectNames are converted to upper case before matching against metadata object
513 +    names, unless the objectname is delimited by double quotes, in which case, the
514 +    double quotes are removed and the remaining string is used (unmodified) to match
515 +    against the metadata object name.
516 +
517 +    If true then the ObjectName is used as is without modification and matched
518 +    against the metadata object name. No attempt is made to remove double quotes.
519 +
520 + 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
521 +    with eoTrigger, these extract types can be used to select only Database Triggers,
522 +    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
523 +
524 + 26. TIBXScript: If an exception occurs during the processing of a statement, the
525 +    statement separate character is now reset to the default (';').
526 +
527 + 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
528 +
529 + 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
530 +    a commit or reconnect statement and instead activated only when next SQL statement
531 +    is executed.
532 +
533 + 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
534 +
535 + 30. TIBXScript: case insensitive regex now used when matching statements instead of
536 +    converting statement to upper case.
537 +
538 + 31. TIBExtract: metadata comments now supported. New published property
539 +    IncludeMetaDataComments (default true). If true then metadata comments included
540 +    in extracted DDL. New Extract Object member eoComments. This may be used with
541 +    ExtractObject method to list all metadata comments.
542 +
543 + 32. TIBExtract: ListObjectNames method added.
544 +
545 + 33. Updated Database component editor to support additional connection string
546 +    types.
547 +
548 + IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
549 +
550 + NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
551 + AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
552 + RELEASE.
553 +
554 + NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
555 +
556 + 1. IBExtract: Identity columns - add additional check for null column for generator name.
557 +
558 + 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
559 +   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
560 +   information). However, this is also a very useful mechanism for returning updated computed by
561 +   column values. Values returned as a result of executing an Insert or Update statement
562 +   replace existing values in the current row for each corresponding column.
563 +
564 +   Previously, if a dataset's select query included read only (computed by) fields then
565 +   an automatic row refresh was performed after an insert or update query had been processed,
566 +   irrespective of the setting of the "ForcedUpdates" property. This has changed such
567 +   that an automatic refresh is no longer performed if an insert or update query contains
568 +   a returning clause that updates one or more fields on the current row. A full row
569 +   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
570 +   field values and the select query contains read only fields. Use of Insert/update
571 +   returning should be significantly more efficient than executing a refresh query.
572 +
573 +   This behaviour change is intended to be backwards compatible and there should be no need to change
574 +   existing programs, other than to improve performance by using the new capability.
575 +
576 + 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
577 +   they are called when the dataset row is being deleted, there is no value in
578 +   updating the current record from the query result. Instead, a new event handler
579 +   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
580 +   an OnDeleteReturning event handler is provided then it is called with the IResults returned
581 +   by the query. The event handler can then interrogate the query results and
582 +   perform whatever action is necessary. For example to confirm, to the user,
583 +   the deletion of a row with the returned values.
584 +
585 + 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
586 +   any Computed By or Identity Columns. The IBTables example has been updated to
587 +   illustrate the computation of the employee Full Name on update.
588 +
589 + 5. TIBTable: The GeneratorField property is now published.
590 +
591 + 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
592 +   When InsertSQL is generated, the Identity columns are not included in the list of values to
593 +   be inserted. A RETURNING clause is added to the insert statement to return the value of
594 +   each Identity column after the insert is executed.
595 +
596 + 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
597 +   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
598 +   Insert..Returning clause.
599 +
600 + 8. TIBGenerator: small performance improvement by not preparing query each time
601 +   a new value is generated.
602 +
603 + 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
604 +
605 + 10. Property editors will now sync table name to a System Table when "Include System
606 +    Tables" is selected and the query is for a System Table.
607 +
608 + 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
609 +    values are no longer converted to milliseconds from TDateTime and then back again
610 +    to TDateTime (the conversion to milliseconds is the default TDataset approach).
611 +
612 + 12. Property Editors handling of Stored Procedures.
613 +    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
614 +      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
615 +      query).
616 +    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
617 +
618 + 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
619 +    can be used to select a package. If non-empty, the stored procedure name is
620 +    expected to be a stored procedure defined in the specified package and the
621 +    generated SQL will be as required for a stored procedure located in a package.
622 +
623 + 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
624 +    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
625 +    which a stored procedure can be selected. With no package name selected, non-package
626 +    stored procedures are listed.
627 +
628 + 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
629 +    for password on reconnect.
630 +
631 + 16. TIBDatabase: use IAttachment for connection default character set id, code page
632 +    and character set name.
633 +
634 + 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
635 +    DB info lookups"
636 +
637 + 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
638 +
639 + 19. Add a property Editor for TIBUpdate.RefreshSQL.
640 +
641 + 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
642 +    parameters. This stops an exception being raised when the field cannot be
643 +    located in the record buffer.
644 +
645 + 21. Property Editors now automatically include System Tables when opened and when the query table
646 +    is a System Table.
647 +
648 + 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
649 +    This avoids errors due to a stale SQRB or SRB being used for the next query.
650 +
651 + 23. IBServices: Service attach parameters now include "expected_db". This is used to
652 +    add the SPB item isc_spb_expected_db. This names a database using
653 +    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
654 +    database. examples/services re-written to illustrate use of "expected_db".
655 +
656 + 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
657 +    This avoids truncated backups when the server returns a timeout (busy) response.
658 +
659 + 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
660 +
661 + 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
662 +    databasenames. These are respectively expanded to the local system's temp directory
663 +    (including trailing delimiter) or to a prescribed data directory (including
664 +    trailing delimiter). Under Unix systems the data directory is a hidden directory
665 +    in the user's home directory. The hidden directory name is either the string returned
666 +    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
667 +    Under Windows, the directory is the same as the Data Directory as decribed
668 +    above but instead prefixed by the User's application data path. These may be
669 +    used to improve application portability for Personal Databases.
670 +
671 + 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
672 +    this has not worked for a long time and is not useful either. FieldDefs should be
673 +    managed using the Fields Editor as with any other dataset. To access the fields
674 +    editor for a TIBTable component, double click on the component. The fields editor
675 +    is then displayed.
676 +
677 + 28. TIBDatabaseInfo: new properties/function
678 +     * DateDBCreated (returns date/time database created)
679 +     * TransactionCount (returns no. of active transactions)
680 +     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
681 +     * PagesFree (Firebird 3 or later)
682 +     * PagesUsed (Firebird 3 or later)
683 +     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
684 +     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
685 +
686 + 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
687 +
688 + 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
689 +
690 + 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
691 +    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
692 +
693 + 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
694 +    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
695 +    firing during backup and restore.
696 +
697 + 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
698 +    for verbose output using the new property "StatisticsRequested".
699 +    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
700 +
701 + 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
702 +
703 + 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
704 +    palette. This uses the online validation feature added in Firebird 2.5. The
705 +    services's properties enable inclusion/exclusion of tables and indexes using
706 +    regular expressions. See.
707 +    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
708 +
709 + 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
710 +    option on a database.
711 +
712 + 37. TIBCustomService: Assign method implemented to allow copying of service login
713 +    context between service API components. "Detach" method now only detaches
714 +    service when last reference to the service interface detaches. Tidy up of
715 +    code for SetActive and Attach methods including password hiding.
716 +
717 + 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
718 +    and used to determine the auth method and protocol used for the connection.
719 +
720 + 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
721 +    a Create Database Statement generated by IBX.
722 +
723 + 40. All IBServices now have an additional published property "PortNo". This may
724 +    be set to a non-standard port number when necessary. If zero then the default
725 +    port number is used.
726 +
727 + 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
728 +    and not just the mouse.
729 +
730 + 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
731 +
732 + 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
733 +    image index and selected image index for each node to be set from a database field.
734 +
735 + 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
736 +    then database schema includes grants to all users. If not present then the
737 +    only user grants included are those to User PUBLIC.
738 +
739 + 45. TIBTreeView: performance improvement. When expanding include both expanded node
740 +    and child nodes in dataset.
741 +
742 +
743 + IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
744 +
745 + 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
746 +   changes.
747 +
748 + 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
749 +   Bug could result in truncated multi-byte character set values.
750 +
751 + 3. Changes consequential on moving fbintf character set utility functions from
752 +   IFirebirdAPI to IAttachment.
753 +
754 + 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
755 +
756 + 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
757 +   results in autocomplete ignoring prefix text.
758 +
759 + 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
760 +   entering a new name into the text box.
761 +
762 + 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
763 +   Firebird rather than recomputing it.
764 +
765 + 8. Property Editor positioning tidy up: All IBX Property editors should now be
766 +   screen centre. Previously some were "poDesigned" which may be inappropriate
767 +   for multi monitor desktops.
768 +
769 + 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
770 +
771 + 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
772 +    a transaction and always reset the object.
773 +
774 + 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
775 +
776 + 13. TIBXScript: Allow for override of database filename in Create Database statements.
777 +
778 + 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
779 +    to a gbak format archive.
780 +
781 + 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
782 +
783 + 16. IBLocaldb: Drop database if error creating an empty database.
784 +
785 + 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
786 +    unless selected node not in current dataset.
787 +
788 + 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
789 +    to TIBCustomService, and IBlocalDB code tidy up.
790 +
791 + 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
792 +    behaviour due to uninitialised variable.
793 +
794 + 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
795 +    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
796 +
797 + 21. IBSQL: When Database changed ensure that all resources are freed.
798 +
799 + 22. IBCustomDataset: When database changed ensure that queries an unprepared.
800 +
801 + 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
802 +    * Line Wrap on SQL Token boundaries (on user command)
803 +    * auto-complete table names in drop down list of table names
804 +    * Double click on tablename or field name adds to SQL text
805 +
806 + 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
807 +
808 + 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
809 +    TVariantArray. Seems to avoid memory corruption in Windows (probably a
810 +    workaround for a problem in fpc 3.0.4 win64).
811 +
812 + 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
813 +
814 + 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
815 +
816 + IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
817 +
818 + 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
819 +   include remote system name.
820 +
821 + 2. TIBExtract: No longer include comment header and COMMIT statement for empty
822 +   tables when data included in output.
823 +
824 + 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
825 +   and timing information to be written to stdout. This may be used to locate
826 +   performance bottlenecks.
827 +
828 + 4. SQLParser: only call "OnChanging" event handler when value is different.
829 +
830 + 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
831 +
832 + 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
833 +   that BindFields is called when the query is next activated. Avoids FieldName
834 +   not found error.
835 +
836 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
837 +   purpose and allows the programmer to define any action they want for Update, Insert
838 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
839 +   filtering of updates, or use of statements such as Grant or Revoke instead of
840 +   normal DML. See User Manual for more information.
841 +
842 + IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
843 +
844 + 1. TIBEvents: Fix uninitialised variable that could result in lost events.
845 +
846 + 2. TIBExtract: Added support for FB3 "USAGE" privilege.
847 +
848 + 3. TIBExtract: data formatted as Charset set "octets" is now output using
849 +   hexadecimal notation.
850 +
851 + 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
852 +   using a simple XML format.
853 +
854 + 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
855 +   grants to these objects.
856 +
857 + 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
858 +   dependency problems restoring complex databases.
859 +
860 + 7. TIBXScript: This component has been restructured to allow for the processing of
861 +   embedded XML in INSERT statements and to support interactive sources in addition
862 +   to non-interactive data sources such as files.
863 +
864 + 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
865 +
866 + 9. TIBXScript: ISQL compatiable Set statements are now supported:
867 +   SET SQL DIALECT
868 +   SET TERM
869 +   SET AUTODDL
870 +   SET BAIL
871 +   SET ECHO
872 +   SET COUNT
873 +   SET STATS
874 +   SET NAMES <character set>
875 +
876 + 10. IBVersion unit added to hold current IBX Version Number information.
877 +
878 + 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
879 +    and domain definitions.
880 +
881 + 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
882 +    fully supported.
883 +
884 + 13. TIBExtract: when a database dump includes data, the generator values are now also set.
885 +
886 + 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
887 +
888 + IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
889 +
890 + See also doc/IBX4LazarusGuide.pdf for important information on
891 + upgrading to IBX2.
892 +
893 + 1. Size property of TIBStringField is now the width in characters of the field
894 +   and not the byte length. This applies only to multi-byte character sets such
895 +   as UTF8. The original approach aligned with TStringField. However, the TStringField
896 +   code is not recognised as a bug and hence this change to align the behaviour.
897 +   The TStringField change is expected in fpc 3.2.0.
898 +
899 + 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
900 +   true (default) then Size property value saved in the lfm is ignored. Size is
901 +   always set from the dynamic information read from the database. It is unclear
902 +   why anyone would want to override this and set Size to false.
903 +
904 + 3. ibxscript: should now handle correctly a Case..End statement within a procedure
905 +   block.
906 +
907 + 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
908 +   exist when an attempt is made to connect to it (run time only) then an attempt
909 +   is made to create the database.
910 +
911 + 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
912 +   has been successfully created as a result of a call to CreateDatabase or when
913 +   creating a database after it was found not to exist.
914 +
915 + 6.  DBControlGrid: a race condition could result in the wrong row image being
916 +    written to the cache. This has been avoided by a trip round the message
917 +    loop before rendering the row image.
918 +
919 + 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
920 +    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
921 +    known to risk corrupt rendering of row images when the control is first
922 +    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
923 +    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
924 +
925 + 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
926 +    a TDateEdit control located on an editor panel.
927 +
928 + 9.  TIBExtract: brought up-to-date plus many bug fixes.
929 +
930 + 10. DBControlGrid: Removed memory leak when updating rows.
931 +
932 + 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
933 +
934 + IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
935 +
936 + 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
937 +   when target codepage is CP_NONE. This is a workaround for
938 +   http://bugs.freepascal.org/view.php?id=30622.
939 +
940 + 2. DBLog option removed from TIBStatisticalService - not supported by server
941 +   since Firebird 1.5.
942 +
943 + 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
944 +   similar.
945 +
946 + 4. IBCodePage: updated mapping between codepages and character id.
947 +
948 + 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
949 +   Firebird. Character sets with a char width of two are not UTF16.
950 +
951 + 6. Strings received from the database are now always transliterated into UTF8
952 +   regardless of the database character set or connection character set. This
953 +   is for compatibility with the LCL.
954 +
955 + IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
956 +
957 + 1. IBBlob: Defer reading of blob until read method called. This avoids having to
958 +   read in an entire blob just to get the size of the blob. General performance
959 +   improvement when opening datasets containing blobs.
960 +
961 + 2. Clearing a  Blob now sets the corresponding field's modified flag.
962 +
963 + 3. IBLookupCombo: When not performing auto-complete, original query sort order
964 +   is now used.
965 +
966 + 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
967 +   determined.
968 +
969 + 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
970 +
971 + 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
972 +   lazarus 1.6.0
973 +
974 + 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
975 +   compilation error.
976 +
977 + IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
978 +
979 + 1. No character set specified for connection: when a text blob is retrieved, the
980 +  character set is determined by looking up the native character set using then
981 +  Firebird API. Otherwise a text mode blob is assumed to have the same character
982 +  set as the connection.
983 +
984 + 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
985 +   for Login Dialog returing a change to the database path.
986 +
987 + 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
988 +   to be changed from that given in the TIBDatabase/TIBServer component and for the
989 +   entered value to be saved on a project specific basis (design time only).
990 +
991 + 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
992 +   column fieldname. If they are the same then it is acts as a look up for the KeyValue
993 +   Otherwise, it sets the column text to the selected ListField Value.
994 +
995 + 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
996 +   column width.
997 +
998 + 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
999 +   and a case insensitive search is requested.
1000 +
1001 + 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
1002 +   or column ListSource.
1003 +
1004 + 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
1005 +   unprepare) when closing and the text has not changed.
1006 +
1007 + 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
1008 +   Less likely to cause a cursor re-use error on Windows.
1009 +
1010 + 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
1011 +   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
1012 +
1013 + 11. TIBTreeView: Guard against nil destination on record changed
1014 +
1015 + 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
1016 +    string type with the code page set to reflect the returned field encoding after
1017 +    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
1018 +    earlier versions.
1019 +
1020 + 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
1021 +    will now result in transliteration to the code page specified for the Firebird driver
1022 +    if the assigned string has a different code page. FPC 3.0.0 onwards only.
1023 +
1024 + 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
1025 +    is ignored and the lc_ctype value, when the database is opened, is set to align with
1026 +    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
1027 +    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
1028 +    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
1029 +    the GETACP is used to determine the Windows code page.
1030 +
1031 + 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
1032 +    name used as the lc_ctype when the database was opened. Only valid while the
1033 +    Database is connected.
1034 +
1035 + 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
1036 +    id that corresponds to the DefaultCharSetName.

1039 +
1040 + 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
1041 +   path is given and database attach fails due to access permission issues on the
1042 +   temp directory or security database, then the attach is retried with "localhost:"
1043 +   prefixing the databasename. This should avoid problems when the database has to
1044 +   be accessed by a local (e.g. classic) server and libfbembed is used.
1045 +
1046 + 2. Windows: revised search order for Firebird DLL:
1047 +     i.   The Firebird Embedded Server in the application Directory.
1048 +     ii.  If the FIREBIRD environment variable is set then the directory this
1049 +          points to is searched for the FB Client DLL and then then underlying
1050 +          "bin" directory.
1051 +     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
1052 +          is used to locate the Firebird installation directory and the underlying
1053 +          "bin" directory is searched for the FB Client DLL.
1054 +     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
1055 +          are searched for the FB Client DLL.
1056 +     v.   The PATH Environment variable is used to search for the FB Client DLL.
1057 +     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
1058 +
1059 + 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
1060 +   See doc/readme.scriptengine and example applications.
1061 +
1062 + 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
1063 +   simplify the use of the embedded firebird server on both Linux and Windows platforms.
1064 +   See dpc/readme.localdatabase and example applications.
1065 +
1066 + 5. IBDynamicGrid: Reordering on column header click should now also work for
1067 +   dynamic columns.
1068 +
1069 + 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
1070 +   between incrementing/decrementing the lock count and signalling the event.
1071 +
1072 + IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
1073 +
1074 + 1.3.2 was never formally released and only made available as beta copies.
1075 +
1076 + 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
1077 +
1078 + 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
1079 +
1080 + 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
1081 +
1082 + 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
1083 +   i.e. when it is a calculated field
1084 +
1085 + 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
1086 +   This problem was due to a race condition between recalculating row heights and
1087 +   determining which row was selected by the mouse click. The row height calculation
1088 +   is now deferred by an extra trip round the message loop allowing the row to
1089 +   be always calculated on the current grid layout rather than risking it being
1090 +   calculated on the grid layout after the expanded row has been shrunk.
1091 +
1092 + 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
1093 +   Windows.
1094 +
1095 + 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
1096 +   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
1097 +   to be determined at runtime. See doc/readme.charactersets.html.
1098 +
1099 + 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
1100 +   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
1101 +
1102 + 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
1103 +   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
1104 +   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
1105 +
1106 +   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
1107 +   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
1108 +   implies no truncation.
1109 +
1110 + 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
1111 +
1112 + 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
1113 +   (avoids "Not in Edit Mode" error).
1114 +
1115 + 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
1116 +
1117 + 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
1118 +    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
1119 +
1120 + 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
1121 +
1122 + 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
1123 +
1124 + 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
1125 +
1126 + 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
1127 +
1128 + IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
1129 +
1130 + 1.   OnCloseUp Event Handler added to TDBLookupProperties
1131 +
1132 + 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
1133 +     problem with row size when exception is called.
1134 +
1135 + 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
1136 +
1137 + 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
1138 +     in a TCustomComboBox and ignores return key if in a TCustomMemo
1139 +
1140 + 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
1141 +     keyed in i.e. when autocomplete not performed
1142 +
1143 + 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
1144 +     console mode applications with all LCL required functions (builtin dialogs and
1145 +     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
1146 +     not included in your project, IBX should compile and link with a console mode program.
1147 +     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
1148 +     console mode application or the IDE will automatically assume that your
1149 +     application is GUI based. Instead, you should include the ibexpressconsolemode package.
1150 +
1151 +     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
1152 +     to use the built in dialogs and cursor management. IBDialogs is
1153 +     included by default if "ibexpress" is in your project source's "uses" clause.
1154 +     This should be the case for all projects created through the IDE. This is why
1155 +     you do not want to add the ibexpress package to console mode applications. The
1156 +     ibexpressconsolemode package has been created to allow console mode programs
1157 +     to avoid adding LCL dependencies when using IBX, while still having the
1158 +     unit search paths set up correctly.
1159 +
1160 +     Existing users should check to ensure that the "ibexpress" unit is included in
1161 +     each project's source file (*.lpr).
1162 +
1163 +     You may find that in order for the IDE to recognise that ibexpressconsolemode
1164 +     exists, you have to first open the package in the IDE and then close it. This
1165 +     adds it to the most recently accessed packages list. To make it permanently
1166 +     available, add the package name to lazarus' staticpackages.inc file.
1167 +
1168 +         Thanks to Julio Jiménez for suggesting support of console mode.
1169 +
1170 + 7.   SQL Parser can now accept quoted strings that include new lines
1171 +
1172 + 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
1173 +     of text on start of edit. This is particularly useful when tabbing to a
1174 +     column and then inserting text.
1175 +
1176 + 9.   New Examples provided for IB Services and ISQLMonitor.
1177 +
1178 + 10. Fix error when writing to blob streams that recorded only the last buffer
1179 +    write in the blob stream. In most cases, this did not cause a problem as the
1180 +    IB Blob Stream is written in a single write. However, with the TDBImage, write
1181 +    of a graphic type prefix was lost which caused a problem when the image could
1182 +        not be automatically recognised.
1183 +
1184 + 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
1185 +    already open" errors due to random numbers used for the cursor name being identical.
1186 +
1187 + 12. IBTable: corrected error that could result in an "Index out of bounds" error
1188 +    when opening the table and the Primary Key is the last or only column in the
1189 +    table. Thanks to Rick Hoover for the fix.
1190 +
1191 + 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
1192 +    of "UTF-8", and update list of available database character sets. Existing
1193 +    users should check the current lc_ctype setting in their applications.
1194 +
1195 + IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
1196 +
1197 + 1.  Firebird Services: avoid List Index error when opening a service with an
1198 +    empty Params property.
1199 +
1200 + 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
1201 +    Link now set up in Loaded method - avoids occasional failure to apply
1202 +    SQL markup on initial open.
1203 +
1204 + 3.  "Employees" example performance improvements when scrolling.
1205 +
1206 + 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
1207 +    TFrame. Force recaching of selected frame to avoid GTK race (results in a
1208 +    random image cached).
1209 +
1210 + 5.  DBControlGrid: Should now react to changes in panel height at run time.
1211 +
1212 + 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
1213 +    even when further rows exist.
1214 +
1215 + 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
1216 +    always be derived from panel height and setting this property can cause confusion.
1217 +    Note for existing projects: to avoid a missing property error at run time,
1218 +    each form using the DBControlGrid must be opened, updated and saved in the IDE
1219 +    in order to remove the property value from the lfm.
1220 +
1221 +
1222 + IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
1223 +
1224 + 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
1225 +    call Prepare before setting parameter values.
1226 +
1227 + 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
1228 +
1229 + 3.  Code tidyup and more robust handling of dsql information result vector.
1230 +
1231 + 4.  Support for centralised handling of transaction status changes. TIBTransaction
1232 +    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
1233 +    and "AfterExecQuery". The first three are called after the same event is called
1234 +    for an IBCustomDataSet descendent using the Transaction. The fourth is called
1235 +    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
1236 +    enable monitoring of transaction status changes for a given transaction to be
1237 +    handled in a single place. For example, when a change to the dataset occurs
1238 +    an indicator can be set that shows the user that in order to save changes,
1239 +    the transaction should be committed.  Rather than doing this per dataset, this
1240 +    can now be done per transaction.
1241 +
1242 + 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
1243 +    the dataset is scrolled. However, any changes to the current row are, by default,
1244 +    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
1245 +    have a new property "DataSetCloseAction" that adds automatic posting of changes
1246 +    on dataset close. If this property is set to dcDiscardChanges (default) then the
1247 +    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
1248 +    then IBX will attempt to post any unsaved changes before the dataset is closed
1249 +    (and after the BeforeClose event handler is called). The exception is when the
1250 +    dataset is being closed as a result of a transaction rollback. In this case,
1251 +    no action is taken and any unsaved  changes are discarded. This avoids both
1252 +    unnecessary overhead and the risk that a validation error may occur in the Post
1253 +    raising an exception and thereby preventing a rollback.
1254 +
1255 + 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
1256 +    In earlier versions, the Display Width was set to the maximum byte width rather than the character
1257 +    width. Display Widths are now corrected by dividing by the max byte width per character.
1258 +    For UTF8 character sets, the byte width is four and hence the Display Width will be
1259 +    the byte width divided by 4. The byte width of each character set is determined
1260 +    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
1261 +    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
1262 +
1263 + 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
1264 +
1265 + 8.  IBLookupComboEditBox: List should now always be restored to full list when the
1266 +    control loses focus. Default Key press default interval reduced to 200ms.
1267 +
1268 + 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
1269 +    when dataset rows are less than visible rows.
1270 +
1271 + 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1272 +    does not exist or DataSet is empty. More responsive on dataset open. New event
1273 +    OnRestorePosition. Column sort disabled if no header row.
1274 +
1275 + 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1276 +    while dataset state is dsInsert. Avoids posting errors.
1277 +
1278 + 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1279 +    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1280 +
1281 + 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1282 +
1283 + 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1284 +    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1285 +    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1286 +    always "posts" the current record regardless or whether or not it may be more appropriate
1287 +    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1288 +    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1289 +    as the first action of the "Post" method and allows the handler to convert the Post
1290 +    into a Cancel if that is the appropriate action on moving to a different row. This is
1291 +    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1292 +    raised here, but it may still be more appropriate to validate a post and signal
1293 +    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1294 +
1295 + 15. On Unix derived systems, the Firebird library name can now be given as a colon
1296 +    separated list. Each library name on the list is tried in turn, in left to right
1297 +    order with the first found being used as the firebird library. By default, on Linux,
1298 +    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1299 +    overidden by the FBLIB environment variable or the OnGetLibraryName function.
1300 +
1301 +    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1302 +    then it will still attempt to access the database via the Firebird Server and will
1303 +    require a username and password. If only the pathname is given, then the username
1304 +    and password should be omitted and the unix file permissions are used to grant
1305 +    access.
1306 +
1307 + IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1308 +
1309 + 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1310 +    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1311 +    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1312 +    corresponds to a row of the linked DataSource. Any data aware control on the
1313 +    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1314 +
1315 + 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1316 +   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1317 +   takes place during database access. This may be useful when there are performance issues with
1318 +   the change of cursor. Setting the property to false suppresses the change of cursor.
1319 +
1320 + 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1321 +   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1322 +   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1323 +   making all changes permanent immediately rather than when the transaction is explicitly
1324 +   committed.
1325 +
1326 + 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1327 +   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
1328 +
1329 + IBX Change Log  version      (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
1330 +
1331 + Development version only.
1332 +
1333 + IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1334 +
1335 + 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1336 +   This is typically used during an "OnBeforeOpen" event handler to manipulate the
1337 +   "Where" and "Having" clauses to implement user specified filters of arbitrary
1338 +   complexity.
1339 +
1340 + 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1341 +   three new data aware controls dependent on IBX and which make use of the SQL Parser.
1342 +   These are:
1343 +
1344 +   - TIBLookupComboEditBox
1345 +   - TIBDynamicGrid
1346 +   - TIBTreeview
1347 +
1348 +   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1349 +   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1350 +   to revise the available list and restrict it to items that are prefixed by the
1351 +   typed text (either case sensitive or case insensitive). Autoinsert allows a
1352 +   newly typed entry to be added to the list dataset and included in the available
1353 +   list items.
1354 +
1355 +   TIBDynamicGrid is a TDBGrid descendent that provides for:
1356 +   - automatic resizing of selected columns to fill the available row length
1357 +   - automatic positioning and sizing of a "totals" control, typically at the
1358 +     column footer, on a per column basis.
1359 +   - DataSet resorting on header row click, sorting the dataset by the selected column.
1360 +     A second click on the same header cell reversed the sort order.
1361 +   - Support for a "Panel Editor". That is on clicking the indicator column, the row
1362 +     is automatically expanded and a panel superimposed on it. The panel can have any
1363 +     number of child controls, typically data aware controls with the same datasource
1364 +     as the grid allowing for editing of additional fields and more complex editors.
1365 +   - Reselection of the same row following resorting.
1366 +   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1367 +     Its properties are specified on a per column basis and allows for one or more
1368 +     columns to have their values selected from a list provided by a dataset.
1369 +     Autocomplete and autoinsert are also available. The existing picklist editor
1370 +     is unaffected by the extension.
1371 +
1372 +   TIBTreeView is a data aware TCustomTreeView.
1373 +
1374 + 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1375 +   zero scale will no longer return an error. An Int64 will be returned instead.
1376 +
1377 + 4. TIBTransaction now has events for Before and After Transaction End and a new function
1378 +   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1379 +
1380 + 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1381 +   repeated multiple times.
1382 +
1383 + 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1384 +   check used to get in the way of using Stored Procedures, and "Update or Insert"
1385 +   statements.
1386 +
1387 + 7. Insert, Modify and Delete property Editors now support Query Generation from
1388 +   Stored Procedures.
1389 +
1390 + 8. Three new examples illustrate the use of the new IB Controls

1393 + IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1394 +
1395 + 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1396 +   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1397 +   Gabor Boros for reporting this problem and for testing the improvements).
1398 +
1399 + 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1400 +   See readme.field+param.names in the doc folder.
1401 +
1402 + 3. IBX SQL Editors will now automatically add double quotes around column names when the database
1403 +   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1404 +
1405 + 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1406 +
1407 + 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1408 +   actions.
1409 +
1410 + 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1411 +   thanks to Yuriy Kopnin for pointing this out).
1412 +
1413 + 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1414 +
1415 + 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1416 +   for both fields and parameter setting.
1417 +
1418 + 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1419 +   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1420 +
1421 + 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1422 +    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1423 +
1424 + 11. TIBTable now has a property editor for "MasterFields"
1425 +
1426 + 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1427 +    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1428 +
1429 + 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1430 +    of settings is unrecognised. Selecting this radio button has no effect on the settings.
1431 +

1433 + IBX Change Log  version                 (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
1434 +
1435 + 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1436 +
1437 + IBX Change Log  version          (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1438 +
1439 + 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1440 +   it is null. This allows for alternative user defined setting of the generator
1441 +
1442 +   Many thanks to Julio Jiménez for this fix
1443 +
1444 + 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1445 +   and suggests that the user may have forgotten to install it.
1446 +
1447 + IBX Change Log  version         (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1448 +
1449 + 1. Conditional compilation used to limit registration of TIntegerField to
1450 +   Lazarus versions less than 1.1
1451 +
1452 + 2. When a database connection is created, character set is now by default set
1453 +   to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1454 +   1250 to 1254.
1455 +
1456 +
1457 + IBX Change Log  version     (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
1458 +
1459 + 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1460 +
1461 +
1462 + IBX Change Log  version    (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1463 +
1464 + 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1465 +   Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1466 +
1467 + 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1468 +   package is changed to do this (which it should do).
1469 +
1470 + IBX Change Log  version (1.0-0)  Sat, 28 Apr 2012 16:43:00 +0100
1471 +
1472 + 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1473 +
1474 + 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1475 +
1476 + 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1477 +
1478 + 4. Property editors should now correctly resize.
1479 +
1480 + 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1481 +   (restored original functionality)
1482 +
1483 + 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1484 +   library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
