1 < FBINTF Change Log  version          (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +0100
1 > IBX Change Log  version (2.6-2 Build 14000) Sat, 05 Aug 2023 10:58:57 +0100
2  
3 < 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
4 <   case sensitive
3 > 1. Fixed repeated "type" keyword in IBBufferCursors. This may cause a compile error
4 >   with later versions of fpc - later than 3.2.2.
5  
6 < 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
6 > 2. IBUpdateSQL. update internal queries if parent dataset database changed.
7  
8 < 3. New API Calls:
9 <        IColumnMetaData.GetStatement
10 <        IColumnMetaData.GetTransaction
11 <        ISQLData.GetStrLength
12 <        IResults.GetStatement
13 <        IAttachment.OpenBlob (using Blob metadata)
14 <        IAttachment.OpenArray (using array metadata)
8 > 3. IBUpdateSQL: Do not prepare an empty internal query.
9  
10 < 4. FBMessages: removal of unused messages
10 > 4. IBBufferCursors: avoid range error when max field no. is > fields.count
11  
12 < 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
12 > IBX Change Log  version (2.6-1 Build 13985) Mon, 17 Jul 2023 14:16:41 +0100
13  
14 < 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
14 > 1. Maintenance update of 2.6.0. This version is still at beta.
15  
16 < FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
16 > 2. Reverse out changes to DrawCellText signature in IBArrayGrid and IBDynamic Grid.
17 >   See https://gitlab.com/freepascal.org/lazarus/lazarus/-/commit/53aaae9c5e2a5edac5b1d2f70739a8ef7b0a9623
18  
19 < 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
20 <   where the second character of the parameter name is a numeric.
19 > 3. ibxscript: When parsing a store procedure or function with a variable name
20 >   enclosed in doublequotes, the double quotes are no longer removed.
21  
22 < 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
28 <   This returns the isc_version connection information as one or more lines.
29 <   This is the same information as returned by isql with the -z option.
22 > IBX Change Log  version (2.6-0 Build 13976) Thu, 22 Jun 2023 13:49:22 +0100
23  
24 < 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
25 <   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
26 <   compiler option then the Firebird 3 API is no longer compiled in.
24 > NOTE: THIS VERSION RE-WRITES THE INTERNAL BUFFER MANAGER AND SHOULD BE CONSIDERED
25 >      AS BETA SOFTWARE. EVEN THOUGH IT HAS PASSED ALL REGRESSION TESTS, IT CANNOT
26 >      BE ASSUMED TO BE PRODUCTION READY UNTIL WIDER USE. PLEASE REPORT ANY
27 >      ISSUES TO support@mwasoftware.co.uk
28  
29 < 4. IColumnMetaData: new method.
29 > 1. Complete rewrite of internal buffer management in order to improve performance
30 >   and maintainability. Highlights:
31  
32 <   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
33 <                        dfDateTime,   {SQL DATETIME}
34 <                        dfTime);
32 >   * Extending the size of the buffer pool no longer has to copy the entire record
33 >     cache. Instead, a new extent is simply added to the buffer pool.
34 >   * A memory to memory copy of each display buffer now is avoided when scolling the
35 >     dataset.
36 >   * A separate set of buffers is now used for calculated fields. This avoids
37 >     having to keep copies of calculated field values in the buffer cache.
38 >   * Compact bitmaps are used to record null status and need to refresh in each
39 >     buffer.
40 >   * Display buffer type changed from PChar to TRecordBuffer in line with change of
41 >     buffer type in FCL-DB.
42  
43 <   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
43 > 2. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is
44 >   to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure.
45  
46 <   This returns the max. number of characters returned by the "AsString" method
47 <   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
46 > 3. TField Provider Flags: pfRefreshOnInsert and pfRefreshOnUpdate are now supported.
47 >   If either or both of these flags are set at design time (using the fields editor)
48 >   then this forces a row refresh on respectively insert or update, or both, when the
49 >   corresponding field is not present in an SQL RETURNING clause.
50  
51 < 5. Additional argument for IAttachment.PrepareWithNamedParameters -
52 <     CaseSensitiveParams: boolean = false
51 > 4. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve
52 >   maintainability and readability and to add identification of primary key fields.
53  
54 <   If this argument is set to true then SQL parameter names are assumed to be case
55 <   sensitive and must be referenced (using ISQLParams.ByName) using the case
56 <   sensitive name.
54 > 5. TIBQuery, TIBDataset and TIBTable. Traditionally, IBX has implemented the Refresh method
55 >   as a refresh of the current row. However, this is different behaviour to that described
56 >   in the FPC documentation for TDataset.Refresh which is described as "refetches the data in
57 >   the dataset from the underlying database, and attempts to reposition the cursor on
58 >   the same record as it was". IBX now complies with the FPC definition of Refresh.
59  
60 < 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
61 <   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
62 <   .AsCurrency) and then subsequently to update the value to a non-numeric string
63 <   using .AsString.
60 > 6. A progammatic Row Refresh should no longer be required.
61 >   Use Insert/Update... returning to refresh any fields that may change following an
62 >   insert or update i.e. Identify fields on Insert only, Computed By, Blob and array fields
63 >   on both. If there are any other fields (e.g. updated by triggers) set the appropriate ProviderFlag
64 >   for the field at Design Time to force a row refresh if not in the returning clause.
65  
66 + 7. It should now be possible to insert a row into an empty unidirectional dataset.
67  
68 + 8. New TIBQuery, TIBDataSet and TIBTable property: BufferChunksInFirstBlock (default 50).
69 +   This gives the number of buffers in the initial block for the buffer pool in
70 +   bi-directional datasets. BufferChunks (default 1000) gives the number of buffers
71 +   in subsequent buffer pool blocks. This avoids large and mostly unused memory allocations
72 +   for small datasets.

74 < FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
74 > IBX Change Log  version (2.5-1 Build 13927) Tue, 6 Dec 2022 23:13:00 +0000
75  
76 < 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
76 > 1. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead.
77  
78 < 2. Restrict IsMultiThread check to Unix only for compatibility with
65 <   https://bugs.freepascal.org/view.php?id=30535
78 > 2. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0
79  
80 < 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
68 <   named parameters and is intended to avoid problems with (e.g.) Execute Block
69 <   and processing internal parameters as statement parameters.
80 > 3. TIBArrayGrid: change DrawCellText declaration to comply with laz 2.3.0
81  
82 < 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
72 <   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
82 > IBX Change Log  version (2.5-0 Build 13868) Fri, 29 Jul 2022 09:52:01 +0100
83  
84 < 5. New function added to IB.pas
84 > 1. TIBTransaction: new properties
85 >    property TransactionID: integer read GetTransactionID;
86 >    property IsReadOnly: boolean read GetIsReadOnly;
87 >    {published}
88 >    property TransactionName: string read FTransactionName write SetTransactionName;
89  
90 <   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
90 > 2. IBCustomDataset: per row blob and array buffer cached clear before processing
91 >   Insert or Update...Returning. This allows blobs and arrays to be returned
92 >   by the statement.
93  
94 <   This allows a Firebird Library to be loaded from an explicit path. use the
79 <   IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
80 <   the library. It is possible to load Firebird libraries from different locations
81 <   simultaneously, each with a distinct IFirebirdAPI.
94 > 3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
95  
96 < FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
96 > 4. TransactionName initialised to a newly generated GUID if empty.
97  
98 < 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
99 <   program compiled with -CR command line switch.
98 > 5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
99 >   for the fbintf package's journaling capability. TIBJournal is used to set the
100 >   file path and filename for the journal file and to Enabled (start journaling) and
101 >   disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
102 >   more information, and comments in IBJournal.pas.
103  
104 < 2. IServiceManager additions (informational):
89 <    function getProtocol: TProtocol;
90 <    function getPortNo: AnsiString;
104 > 6. TIBDatabase.InternalTransaction is now a read only transaction.
105  
106 < 3. IServiceManager improved error handling. Interfaces changed:
107 <    function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
94 <    function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
95 <    function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
106 > 7. Bug fix: blob id no longer set to null on update when blob has not been
107 >   retrieved.
108  
109 < 4. IAttachment addition (informational)
110 <    function GetSecurityDatabase: AnsiString;
109 > 8. Row auto refreshed on update/insert if blob or array field updated and field
110 >   not in a returning clause.
111  
112 < 5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
113 <   thus now returns accumulated stats for a select statement from opening a cursor
114 <   up to the last fetch.
112 > 9. ColumnCount moved from record buffer header to a single per dataset count. Reduces
113 >   buffer overhead and avoids problem when refresh query has a different column
114 >   count to select query i.e. incorrectly changing number of columns.
115  
116 < 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
105 <   the problem.
116 > 10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
117  
118 < 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
119 <   replaces deprecated "comp" type.
118 > 11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
119 >    string. Note that the Version property returns an InterBase compatible version string.
120  
121 < 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
121 > 12. IBExtract: ensure sql identifiers returned as a LIST are always quoted.
122  
123 < 11. URL Connection Strings: inet4 and inet6 now recognised.
123 > IBX Change Log  version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000
124  
125 < 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
125 > 1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
126 >   This is for compatibility with Firebird 5 where Update...Returning can return
127 >   a cursor.
128  
129 < 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
129 > IBX Change Log  version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
130  
131 + 1. Add try-..except check when initially loading library in IDE. This should
132 + ensure that IDE continues to load even when a failure occurs in IBX load
133 + library.
134  
135 < FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
135 > 2. IBXScript: now recognises a CASE...END block within a stored procedure and
136 >   hence will correctly detect end of the outer containing block when the block
137 >   contains a SELECT ... CASE ... END construct.
138  
139 < 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
139 > 3. IBExtract: some further tidying up to remove extraneous white space.
140  
141 < 2. IAttachment: add two new methods
142 <     function HasDefaultCharSet: boolean;
125 <     function GetDefaultCharSetID: integer;
141 > 4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
142 >   errors when extra elements are added to DB.TFieldType.
143  
144 <   These return, respectively, true if a connection default character set was
128 <   specified and the character set id of the connection default character set.
129 <   The DefaultCharSetID is cached when the connection is opened and hence does not
130 <   require a database lookup.
144 > 5. IBUpdate: updated to reflect changes to ISQLParam.
145  
146 < 3. Avoid exception when a text blob is a stored procedure parameter.
146 > 6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
147  
148 < 4. Update test suite to include a test for a stored proc returning a text blob.
148 > 7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
149  
150 < 5. IAttachment: add
137 <      function GetRemoteProtocol: AnsiString;
138 <      function GetODSMajorVersion: integer;
139 <      function GetODSMinorVersion: integer;
140 <      function GetAuthenticationMethod: AnsiString;
150 > 8. IBSQL: Support for scrollable cursors added (note: local databases only)
151  
152 <   These results are cached when the connection is opened and hence do not
143 <   require a database lookup.
152 > IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
153  
154 < 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
155 <   connect string used to create/connect to the database.
154 > 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
155 >   exception of those defined to be one byte wide e.g. DBImplementationNo.
156  
157 < 7. IAttachment: Create Database using SQL statement. The username and password
149 <   are now extracted and used to populate a DPB made available via IAttachment.getDPB.
150 <   It is now possible to use IAttachment disconnect/connect to reconnect to
151 <   a database for which the initial connection was established by a create
152 <   database sql statement. Available in FPC only.
157 > 2. TIBSQL: Batch Update/Insert support added.
158  
159 < 8. Update Test 1 to test 5, 6 and 7 above.
159 > 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
160 >   is no longer automatically converted to upper case when it is syntactically a
161 >   SQL Identifier. This is to support the use of stored procedures defined e.g.
162 >   as CREATE PROCEDURE "iCASE".
163  
164 < 9. IBUtils code tidy up.
164 >   There could be a backwards compatibility issue when the StoredProcName was entered
165 >   manually at design time. That is not selected from the drop down list. If the
166 >   StoredProcName is entered in mixed case and the procedure was declared e.g. as
167 >   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
168 >   ensure that the value of the StoredProcName is all upper case, unless it was
169 >   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
170 >   quotes).
171  
172 < 10. Parameter Block interfaces "find" method. As documented, this should have
173 <   returned a nil interface when the item could not be found. Instead, an empty
174 <   interface item was returned. "Find" now works as documented and will return
161 <   a nil interface if the item cannot be found.
172 >   Note that when a stored procedure name was declared delimited in double quotes,
173 >   as in the first example above, the value of the StoredProcName property must not
174 >   include the delimiters (double quotes).
175  
176 < 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
176 > 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
177 >   upgrade.conf was not found. This replaces silently ignoring the problem.
178  
179 < 12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
180 <    requests with additional parameters. This is to enable support for fb_info_page_contents
181 <    (return of page contents). Response to fb_info_page_contents returned as
168 <    a string with code page CP_NONE.
179 > 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
180 >   'Version.%.3d' and is used to generate the section header names (for a given
181 >   version no.) in the upgrade.conf file.
182  
183 < 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
171 <    test suite updated.
183 > IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
184  
185 < 14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
186 <    a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
185 > 1. -c command line option added to fbsql example program. Used to set connection
186 >   character set.
187  
188 < 15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
177 <    An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
178 <    default connection port to be specified.
188 > IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000

190 < FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
190 > 1. Firebird 4 support added.
191  
192 < 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
193 <   Scale is no longer ignored.
192 > 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
193 >   extended precision NUMERIC fields are supported.
194  
195 < 2. Fix issues with setting SQL Param values using SetAsString with Date values
186 <   not in locale format but which are recognised by Firebird. Date values that
187 <   cannot be converted to a string using Pascal library are now passed through
188 <   to Firebird as Text Strings.
195 > 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
196  
197 < 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
198 <   UTF8 and not UNICODE_FSS.
197 > 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
198 >   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
199  
200 < 4. Charset ID problem. When using Firebird 3, with no default database character set
201 <   and a column has a non-default collation specified, an incorrect character set
202 <   id was being reported that could result in a 'division by zero' error when
203 <   used by IBX. This has now been fixed.
200 > 5. IBExtract now supports FB4 enhancements:
201 >   - new data types as above
202 >   - Identity column extensions
203 >   - Default user role
204 >   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
205 >   - Internal Functions
206  
207 < 5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
199 <   CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
200 <   the character sets supported can be updated on a per database basis. That is
201 <   it is possible to add a (Firebird) user defined character set to a database.
207 > 6. IBExtract: new event: OnExtractLines.
208  
209 < 6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
204 <   set supported by Firebird with the API.
209 > 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
210  
211 < 7. Add missing isc_info_db_read_only to list of decoded Database Information items
212 <   in FBOutputBlock.pas and update test suite to include this item.
211 > 8. IBXServices: Server version no. parsing now allows any letter before major version number
212 >   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
213  
214 < 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
214 > 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
215 >   format for rendering a time zone.
216  
217 < 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
218 <   library or finding it by disk location, the PATH environment variable is now also set to
213 <   include the FIREBIRD directory. This is to ensure that the correct dlls in the
214 <   firebird client library dependencies are loaded.
217 > 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
218 >     to convert TIME WITH TIME ZONE data type values to and from GMT.
219  
220 < 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
220 > 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
221 >    IIBGUIInterface and IIBTimerInf respectively.
222  
223 < 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
223 > 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
224 >    now accessible as properties of TIBDatabase and TIBTransaction respectively.
225  
226 < 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
226 > 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
227 >    truncated to its fixed character width rather than being right padded with
228 >    white space to the maximum data size.
229  
230 < 13. FB30Statement: A check has been added to ensure that all SQL Parameters
231 <    have been given a value (including NULL). Previously, failing to set the
232 <    value of an SQL Parameter could give rise to unpredictable results or
225 <    an SQLDA error.
230 > 14. TIBTable.Empty table. In additional to deleting all records in the underlying
231 >    table, the internal buffers are now also flushed ensuring that the TIBTable is
232 >    also empty.
233  
234 < 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
234 > 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
235  
236 < 15. FBAttachment: Avoid string reference count error when processing an Ansistring
237 <    parameter in an array of const passed to IAttachment.OpenCursor, etc.
236 > 16. TIBXControlService descendents: DatabaseName may now be set using a database
237 >    connect string. The database name is extracted from the connect string.
238  
239 < 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
233 <    of const passed to IAttachment.OpenCursor, etc.
239 > 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
240  
241 + 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.

243 < FBINTF Change Log  version             (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
243 > 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
244 >    not being present as required.
245  
246 < 1. Change syntax to Mode Delphi
246 > 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
247 >    version that can be customised to work with other database drivers.
248  
249 < 2. Change all uses of string type to explicit AnsiString in order to ensure
250 <   compatibility between Delphi and FPC.
249 > 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
250 >    unnecessary CR at end of line on Unix platforms.
251  
252 < 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
253 <   defined for each interface.
252 > 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
253 >    seconds in order to reduce risk of message loss.
254  
255 < 4. Generics syntax variations for Delphi added
255 > 23. ISQLMonitor: read and write count statistics now available via:
256 >      property TIBSQLMonitor.ReadCount;
257 >      IIBSQLMonitorHook.GetWriteCount: integer;
258  
259 < 5. PChar replaced with PByte expect where an actual string is being referenced,
249 <   where PAnsiChar is used instead.
259 > 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
260  
261 < 6. Review of type definitions in IBExternals to ensure Delphi compatibility
261 > IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
262  
263 < 7. Testsuite updated for Delphi
263 > 1.  TIBStringField: when a string value is read from a dataset buffer, if the
264 >    number of UTF8 characters exceeds the string size then string is truncated
265 >    to the maximum string size. This is  usually a problem with fixed width columns
266 >    right padded with white space.
267  
268 < FBINTF Change Log  version            (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
268 > 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
269 >    If SQLFiltered is set then when a dataset is opened, each line in the
270 >    SQLFilterParams property is assumed to be a SQL condition clause and
271 >    ANDed into the Where clause of the SQL Select statement provided as a
272 >    dataset property. Each such SQL condition thus acts as an additional filter
273 >    on the dataset.
274  
275 < 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
276 <   large blobs and the FB3 API.
275 > 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
276 >    side filters).
277  
278 < 2. Update Event Handling algorithm to avoid looping due to recreation of the
279 <   event block.
278 > 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
279 >   text matches complete entry.
280  
281 < 3. Avoid invalid XSQLDA error when the only parameter is updated to null
281 > 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
282 >   dataset are active (avoids risk of access violation if master is inactive)
283  
284 < 4. Array Handling: fix problem with text arrays with character set none. When the
266 <   DB connection has a default character set (e.g. UTF8), an error is raised by
267 <   Firebird if the space allocated is not enough to allow for transliteration, even
268 <   though it is not required for character set none.
284 > 6. TIBEvents: Registered property can now be set at design time even if database not open
285  
286 < 5. IBUtils: List of reserved words brought up-to-date
286 > 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
287 >   This should prevent "spillover" of events between sessions.
288  
289 < 6. Add ISQL style performance statistics collection to IStatement
289 > 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
290 >   This should ensure that the internal buffer is set up correctly and avoids
291 >   a duplicate initial row.
292  
293 < 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
294 <   CREATE DATABASE statement.
293 > 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
294 >   That is, the DataSize should be the field size * character set width. The
295 >   value returned by DataSize is now the same as the Dataset buffer size reserved
296 >   for the field.
297  
298 < 8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in
278 <   an array dimension is not mistaken for a named parameter prefix.
298 > 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
299  
300 < 9. Trim function no longer applied to result of GetAsString for SQL_TEXT
301 <   when Character set is octets. Avoids loss of non printable characters at start of string.
300 > 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
301 >    and vice-versa. This may result in an exception being raised (correctly) for
302 >    older programs when using dataset fields added to a form and the database has been
303 >    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
304 >    In such cases, the field needs to be deleted in the IDE fields editor and then
305 >    added back in.
306  
307 < 10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
308 <    statistics for the last action. Requires use of procedure IStatement.EnableStatistics
285 <    to enable stats gathering.
307 > 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
308 >    false if query contains only white space and not just empty.
309  
310 < 11. API Version information added as constants to IB.pas
310 > 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
311 >    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
312 >    is cancelled.
313  
314 < 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
314 > 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
315 >    called on a null field.
316  
317 < 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
317 > 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
318 >    results in an empty dataTC86                Client side Filtered Dataset    1       X
319 > set.
320  
321 < FBINTF Change Log  version                                      (1.0-0) Tue, 06 Dec 2016 10:33:47 +0000
321 > 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
322 >    a cached update is applied and an exception is raised.
323  
324 < 1. Initial Release
324 > 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
325  
326 + 17. Console Mode Local Database support: backup/restore should now work correctly.
327 +
328 + 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
329 +    possible and an exception raised.
330 +
331 + 19. MinimumVersionNo added to Local Database Support. Database will not open if
332 +    below this version no. and upgrade not possible.
333 +
334 + IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
335 +
336 + 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
337 +    not SQL Identifiers are now supported.
338 +
339 + 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
340 +    passed to the Firebird engine for execution.
341 +
342 + 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
343 +    is made to scroll back.
344 +
345 + 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
346 +
347 + 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
348 +   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
349 +
350 + 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
351 +   validated. If no match is found in the list of field names and the database has
352 +   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
353 +   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
354 +
355 + 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
356 +   with fpc 3.2.
357 +
358 + IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
359 +
360 +
361 + 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
362 +   and is used to override the default settings in the client side "firebird.conf" This
363 +   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
364 +   Each line of the string list should be a setting in the same format as "firebird.conf".
365 +   For example "WireCompression = true" in order to request wire compression on the client side.
366 +
367 +   Note: explicit settings in the client side "firebird.conf" appear to take precedence
368 +   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
369 +   also require a compatible setting in the server side "firebird.conf". For example
370 +   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
371 +   compression to be used.
372 +
373 +   Whether or not WireCompression or WireCrypt are in use can be checked using the information
374 +   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
375 +   ibx/examples/dbinfo for examples of how to display this information.
376 +
377 + 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
378 +   is a "convenience" property. If set the "WireCompression=true" is added to the
379 +   ConfigOverrides. If unchecked then this setting is removed.
380 +
381 + 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
382 +   not "INT64".
383 +
384 + 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
385 +   These are:
386 +    property TimestampFormat: string;
387 +    property DateFormat: string;
388 +    property TimeFormat: string;
389 +
390 +   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
391 +   DATETIME and TIME. The format strings use the standard FPC date/time format
392 +   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
393 +
394 +   If any of the above properties are set to an empty string, then the locale default
395 +   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
396 +   locale default is extended by appending '.zzz' to include milliseconds.
397 +
398 +   TIBCSVDataOut by default sets these properties to the empty string, while the other
399 +   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
400 +
401 + 5. New published property for TIBCSVDataOut:
402 +     property QuoteStrings: boolean (default true)
403 +
404 +   If false then strings are unquoted, otherwise, the QuoteChar property value is
405 +   used to delimit each and every string in the output.
406 +
407 + 6. New published properties for TIBCSVDataOut:
408 +    property FieldSeparator: string;
409 +    property HeaderSeparator: string;
410 +
411 +   Respectively, these provide the separator character(s) used to separate fields
412 +   in data and header rows. Both default to ','.
413 +
414 + 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
415 +    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
416 +    property OnFormatTextString;
417 +
418 +   This event handler can be used to process text strings before they are included
419 +   in the output e.g. to replace unprintable characters with alternative strings.
420 +   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
421 +
422 + 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
423 +   Uses "FindParam" if in order to find out if a parameter with a given name exists
424 +   and without raising and exception if it does not.
425 +
426 + 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
427 +   consistency with SQL queries.
428 +
429 + 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
430 +    When true, SQL statement parameter names are parsed case sensitive. Note for
431 +    TIBDataSet only applies to Select query.
432 +
433 + 11. IBEvents: removing a TIBEvent component from a form should no longer result in
434 +    an IDE exception.
435 +
436 + 12. LocalDBSupport: initial database creation should now work correctly
437 +    when the schema source is an sql file.
438 +
439 + 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
440 +    when defined, this handler will be called by the internal TIBXScript during
441 +    initial database creation when the schema source is an sql file and may be used
442 +    to provide a visual indication of progress in console mode.
443 +
444 + 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
445 +    to true while a new local database is being created and its schema populated.
446 +    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
447 +    when the database is disconnected/connected during the create DB procedure.
448 +
449 + 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
450 +    are now always ignored and replaced by the user name and password provided as
451 +    the login parameters for the TIBDatabase referenced from the TIBXScript. The
452 +    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
453 +    completely ignored if this property is true.
454 +
455 + 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
456 +    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
457 +    ImageIndex and SelectImageIndex values on AddNode.
458 +
459 + 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
460 +    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
461 +    the same database connection.
462 +
463 + 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
464 +    if provided, this should be an conditional SQL expression suitable for
465 +    including in an SQL Select statement "where" clause. If non-empty and the
466 +    "Filtered" property is true then the SQL expression provided as the value of
467 +    the "Filter" property is "ANDed" with any existing condition statement
468 +    in the SQL statement's "Where" clause.
469 +
470 +    If the "Filter" property is set at run time, the "Filtered" property is true
471 +    and the dataset is already open, then the dataset is closed and re-opened automatically.
472 +
473 +    The "Filter" condition may include IBX style parameters. In which case, their
474 +    value must be set by the dataset's "OnBeforeOpen" event handler.
475 +
476 +    This is a public property for TIBDataSet and TIBQuery query and intended for
477 +    use at run time.
478 +
479 +    Note: The property is a published property of TIBTable. The TIBTable functionality
480 +    is unaffected by this change.
481 +
482 + IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
483 +
484 + 1. Remove need to check for IsMultiThread by providing access to GUI timers via
485 +   IBGUIInterface. Note: master/detail delay timer does not apply to console
486 +   mode apps.
487 +
488 + 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
489 +   statement. This avoids problems if "Execute Block" is used as the Query.
490 +
491 + 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
492 +   internal SQL tokeniser routines.
493 +
494 + 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
495 +   as a select statement, with or without CTEs.
496 +
497 + 5. IBSQLParser: parser now recognises the "ROWS" clause.
498 +
499 + 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
500 +   internal SQL tokeniser routines.
501 +
502 + 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
503 +    being raised for valid set statements processed by a data formatter.
504 +
505 + 8. New published property for TIBDatabase and TIBXServicesConnection. This is
506 +   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
507 +   the path of the Firebird Library used by the database/services connection.
508 +
509 + 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
510 +   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
511 +   services connection.
512 +
513 + 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
514 +   or param name is not a valid SQL identifier.
515 +
516 + 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
517 +    view of whether the text box should be editable when no DataSource is specified.
518 +    TIBLookupComboEditBox has been updated to workaround this problem. As long as
519 +    ReadOnly is false, the text box is editable when no DataSource is specified.
520 +
521 + 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
522 +    the FBLIB environment variable. If you do not want to permit this then you
523 +    must modify the Register procedure in the design/IBDBReg.pas unit to remove
524 +    this setting.

529 +   Utf8EscapeControlChars
530 +
531 + IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
532 +
533 + IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
534 + all previous copies of the IBX source code tree before installing this release.
535 +
536 + The IBX packages used by most users have not changed, with one exception. The
537 + IBServices unit has been moved to the package iblegacyServices.lpk. To continue
538 + to use the IBServices unit in your applications, please add the iblegacyServices
539 + to the list of dependencies. To do this, open the Project Inspector and select
540 + Add->New Requirement and select "ibLegacyServices" from the list of available
541 + packages.
542 +
543 + 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
544 +   the IBServices unit providing what is intended to be a clearer and easier to
545 +   use set of IB Services components. See Chapter 10 of the IBX User Guide for
546 +   more information and the guide to "Firebird Service Management Using IBX".
547 +   As indicated above, the legacy services components are still available and
548 +   provided in a separate package. There is no need to update working applications
549 +   using the older versions except for an additional package dependency.
550 +
551 + 2. The IBX packages and source code tree have been re-organised in an attempt to
552 +   finally get rid of the "duplicate ppu" warnings. This re-organisation should
553 +   not affect existing users. Section 2.3 of the IBX User Guide describes the
554 +   new set of IBX packages.
555 +
556 + 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
557 +   updated to use the new Services API components.
558 +
559 + 4. The iblocal package has been updated to use the new Services API components.
560 +
561 + 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
562 +   TIBXSecurityService. It had been wrongly classified in the previous version
563 +   as a per database configuration item. It is global to a server and hence
564 +   correctly positioned as part of the Security Package. In the DBAdmin example,
565 +   the setting has moved to the mappings page.
566 +
567 + 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
568 +   are ignored.
569 +
570 + 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
571 +   closed before the database is dropped. Before and After Disconnect event handlers
572 +   are also fired.
573 +
574 + 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
575 +   is started and not just the first time.
576 +
577 + 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
578 +   depenendency with comp type.
579 +
580 + 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
581 +
582 + 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
583 +    then this is recognised and not ignored.
584 +
585 + 12. TIBDataSet, TIBQuery, TIBTable: additions:
586 +    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
587 +    function GetPerfStatistics(var stats: TPerfCounters): boolean;
588 +    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
589 +
590 +    GetRowsAffected returns the affected row counts from the last insert/update/delete
591 +    if EnableStatistics = true then GetPerfStatistics returns the current stats
592 +    counters for the select query. Note: stats accumulate after each fetch from
593 +    the database. To get total query cost after open, call the "Last" method
594 +    and then GetPerfStatistics.
595 +
596 +    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
597 +
598 + 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
599 +    in parenthesises.
600 +
601 + 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
602 +    SQL identifiers are always delimited by double quotes. If false, then they are
603 +    only delimited if the identifier is a reserved word, contains lower case or special
604 +    characters. Set this property to true to retain previous behaviour.
605 +
606 + 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
607 +    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
608 +
609 + 16. TIBDataSet, TIBQuery, TIBTable: addition:
610 +       property MasterDetailDelay: integer {defaults to zero}
611 +
612 +    When non-zero and the dataset is a detail table referencing a master table
613 +    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
614 +    then a synchronisation delay is added (in milliseconds) between the master
615 +    row changing and the detail dataset being re-opened. If the master dataset
616 +    is scrolled before the delay expires then the delay is reset. This can be used
617 +    to avoid performance overheads when scrolling through a large master dataset.
618 +
619 +    Note: uses fptimer and hence requires a thread manager. Under Linux the
620 +    chreads unit must be included in your project. TTimer is not used in order
621 +    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
622 +
623 + 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
624 +    with Extract Option eoDatabase.
625 +
626 + 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
627 +    When a deLayoutChanged event is reported on the ListSource dataset, the
628 +    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
629 +    relationship with the control's datasource (master).
630 +
631 + 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
632 +
633 + 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
634 +    stubs. Pedantic fix really, as procedures output in dependency order anyway.
635 +
636 + 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
637 +    DDL (Firebird 3 and later only).
638 +
639 + 22. TIBLookupComboBox Autocomplete Fixes:
640 +    i. Only appended text is now selected after autocomplete.
641 +    ii. Uppercase keys no longer ignored for autocomplete.
642 +    iii. Retain Prefix case is now honoured correctly.
643 +    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
644 +        before autocomplete performed. i.e. behaviour now the same as when
645 +        no DataSource assigned.
646 +
647 + 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
648 +    between SQL statements.
649 +
650 + 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
651 +    ObjectNames are converted to upper case before matching against metadata object
652 +    names, unless the objectname is delimited by double quotes, in which case, the
653 +    double quotes are removed and the remaining string is used (unmodified) to match
654 +    against the metadata object name.
655 +
656 +    If true then the ObjectName is used as is without modification and matched
657 +    against the metadata object name. No attempt is made to remove double quotes.
658 +
659 + 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
660 +    with eoTrigger, these extract types can be used to select only Database Triggers,
661 +    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
662 +
663 + 26. TIBXScript: If an exception occurs during the processing of a statement, the
664 +    statement separate character is now reset to the default (';').
665 +
666 + 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
667 +
668 + 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
669 +    a commit or reconnect statement and instead activated only when next SQL statement
670 +    is executed.
671 +
672 + 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
673 +
674 + 30. TIBXScript: case insensitive regex now used when matching statements instead of
675 +    converting statement to upper case.
676 +
677 + 31. TIBExtract: metadata comments now supported. New published property
678 +    IncludeMetaDataComments (default true). If true then metadata comments included
679 +    in extracted DDL. New Extract Object member eoComments. This may be used with
680 +    ExtractObject method to list all metadata comments.
681 +
682 + 32. TIBExtract: ListObjectNames method added.
683 +
684 + 33. Updated Database component editor to support additional connection string
685 +    types.
686 +
687 + IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
688 +
689 + NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
690 + AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
691 + RELEASE.
692 +
693 + NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
694 +
695 + 1. IBExtract: Identity columns - add additional check for null column for generator name.
696 +
697 + 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
698 +   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
699 +   information). However, this is also a very useful mechanism for returning updated computed by
700 +   column values. Values returned as a result of executing an Insert or Update statement
701 +   replace existing values in the current row for each corresponding column.
702 +
703 +   Previously, if a dataset's select query included read only (computed by) fields then
704 +   an automatic row refresh was performed after an insert or update query had been processed,
705 +   irrespective of the setting of the "ForcedUpdates" property. This has changed such
706 +   that an automatic refresh is no longer performed if an insert or update query contains
707 +   a returning clause that updates one or more fields on the current row. A full row
708 +   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
709 +   field values and the select query contains read only fields. Use of Insert/update
710 +   returning should be significantly more efficient than executing a refresh query.
711 +
712 +   This behaviour change is intended to be backwards compatible and there should be no need to change
713 +   existing programs, other than to improve performance by using the new capability.
714 +
715 + 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
716 +   they are called when the dataset row is being deleted, there is no value in
717 +   updating the current record from the query result. Instead, a new event handler
718 +   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
719 +   an OnDeleteReturning event handler is provided then it is called with the IResults returned
720 +   by the query. The event handler can then interrogate the query results and
721 +   perform whatever action is necessary. For example to confirm, to the user,
722 +   the deletion of a row with the returned values.
723 +
724 + 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
725 +   any Computed By or Identity Columns. The IBTables example has been updated to
726 +   illustrate the computation of the employee Full Name on update.
727 +
728 + 5. TIBTable: The GeneratorField property is now published.
729 +
730 + 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
731 +   When InsertSQL is generated, the Identity columns are not included in the list of values to
732 +   be inserted. A RETURNING clause is added to the insert statement to return the value of
733 +   each Identity column after the insert is executed.
734 +
735 + 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
736 +   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
737 +   Insert..Returning clause.
738 +
739 + 8. TIBGenerator: small performance improvement by not preparing query each time
740 +   a new value is generated.
741 +
742 + 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
743 +
744 + 10. Property editors will now sync table name to a System Table when "Include System
745 +    Tables" is selected and the query is for a System Table.
746 +
747 + 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
748 +    values are no longer converted to milliseconds from TDateTime and then back again
749 +    to TDateTime (the conversion to milliseconds is the default TDataset approach).
750 +
751 + 12. Property Editors handling of Stored Procedures.
752 +    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
753 +      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
754 +      query).
755 +    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
756 +
757 + 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
758 +    can be used to select a package. If non-empty, the stored procedure name is
759 +    expected to be a stored procedure defined in the specified package and the
760 +    generated SQL will be as required for a stored procedure located in a package.
761 +
762 + 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
763 +    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
764 +    which a stored procedure can be selected. With no package name selected, non-package
765 +    stored procedures are listed.
766 +
767 + 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
768 +    for password on reconnect.
769 +
770 + 16. TIBDatabase: use IAttachment for connection default character set id, code page
771 +    and character set name.
772 +
773 + 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
774 +    DB info lookups"
775 +
776 + 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
777 +
778 + 19. Add a property Editor for TIBUpdate.RefreshSQL.
779 +
780 + 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
781 +    parameters. This stops an exception being raised when the field cannot be
782 +    located in the record buffer.
783 +
784 + 21. Property Editors now automatically include System Tables when opened and when the query table
785 +    is a System Table.
786 +
787 + 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
788 +    This avoids errors due to a stale SQRB or SRB being used for the next query.
789 +
790 + 23. IBServices: Service attach parameters now include "expected_db". This is used to
791 +    add the SPB item isc_spb_expected_db. This names a database using
792 +    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
793 +    database. examples/services re-written to illustrate use of "expected_db".
794 +
795 + 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
796 +    This avoids truncated backups when the server returns a timeout (busy) response.
797 +
798 + 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
799 +
800 + 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
801 +    databasenames. These are respectively expanded to the local system's temp directory
802 +    (including trailing delimiter) or to a prescribed data directory (including
803 +    trailing delimiter). Under Unix systems the data directory is a hidden directory
804 +    in the user's home directory. The hidden directory name is either the string returned
805 +    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
806 +    Under Windows, the directory is the same as the Data Directory as decribed
807 +    above but instead prefixed by the User's application data path. These may be
808 +    used to improve application portability for Personal Databases.
809 +
810 + 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
811 +    this has not worked for a long time and is not useful either. FieldDefs should be
812 +    managed using the Fields Editor as with any other dataset. To access the fields
813 +    editor for a TIBTable component, double click on the component. The fields editor
814 +    is then displayed.
815 +
816 + 28. TIBDatabaseInfo: new properties/function
817 +     * DateDBCreated (returns date/time database created)
818 +     * TransactionCount (returns no. of active transactions)
819 +     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
820 +     * PagesFree (Firebird 3 or later)
821 +     * PagesUsed (Firebird 3 or later)
822 +     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
823 +     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
824 +
825 + 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
826 +
827 + 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
828 +
829 + 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
830 +    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
831 +
832 + 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
833 +    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
834 +    firing during backup and restore.
835 +
836 + 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
837 +    for verbose output using the new property "StatisticsRequested".
838 +    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
839 +
840 + 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
841 +
842 + 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
843 +    palette. This uses the online validation feature added in Firebird 2.5. The
844 +    services's properties enable inclusion/exclusion of tables and indexes using
845 +    regular expressions. See.
846 +    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
847 +
848 + 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
849 +    option on a database.
850 +
851 + 37. TIBCustomService: Assign method implemented to allow copying of service login
852 +    context between service API components. "Detach" method now only detaches
853 +    service when last reference to the service interface detaches. Tidy up of
854 +    code for SetActive and Attach methods including password hiding.
855 +
856 + 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
857 +    and used to determine the auth method and protocol used for the connection.
858 +
859 + 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
860 +    a Create Database Statement generated by IBX.
861 +
862 + 40. All IBServices now have an additional published property "PortNo". This may
863 +    be set to a non-standard port number when necessary. If zero then the default
864 +    port number is used.
865 +
866 + 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
867 +    and not just the mouse.
868 +
869 + 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
870 +
871 + 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
872 +    image index and selected image index for each node to be set from a database field.
873 +
874 + 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
875 +    then database schema includes grants to all users. If not present then the
876 +    only user grants included are those to User PUBLIC.
877 +
878 + 45. TIBTreeView: performance improvement. When expanding include both expanded node
879 +    and child nodes in dataset.
880 +
881 +
882 + IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
883 +
884 + 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
885 +   changes.
886 +
887 + 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
888 +   Bug could result in truncated multi-byte character set values.
889 +
890 + 3. Changes consequential on moving fbintf character set utility functions from
891 +   IFirebirdAPI to IAttachment.
892 +
893 + 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
894 +
895 + 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
896 +   results in autocomplete ignoring prefix text.
897 +
898 + 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
899 +   entering a new name into the text box.
900 +
901 + 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
902 +   Firebird rather than recomputing it.
903 +
904 + 8. Property Editor positioning tidy up: All IBX Property editors should now be
905 +   screen centre. Previously some were "poDesigned" which may be inappropriate
906 +   for multi monitor desktops.
907 +
908 + 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
909 +
910 + 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
911 +    a transaction and always reset the object.
912 +
913 + 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
914 +
915 + 13. TIBXScript: Allow for override of database filename in Create Database statements.
916 +
917 + 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
918 +    to a gbak format archive.
919 +
920 + 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
921 +
922 + 16. IBLocaldb: Drop database if error creating an empty database.
923 +
924 + 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
925 +    unless selected node not in current dataset.
926 +
927 + 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
928 +    to TIBCustomService, and IBlocalDB code tidy up.
929 +
930 + 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
931 +    behaviour due to uninitialised variable.
932 +
933 + 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
934 +    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
935 +
936 + 21. IBSQL: When Database changed ensure that all resources are freed.
937 +
938 + 22. IBCustomDataset: When database changed ensure that queries an unprepared.
939 +
940 + 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
941 +    * Line Wrap on SQL Token boundaries (on user command)
942 +    * auto-complete table names in drop down list of table names
943 +    * Double click on tablename or field name adds to SQL text
944 +
945 + 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
946 +
947 + 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
948 +    TVariantArray. Seems to avoid memory corruption in Windows (probably a
949 +    workaround for a problem in fpc 3.0.4 win64).
950 +
951 + 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
952 +
953 + 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
954 +
955 + IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
956 +
957 + 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
958 +   include remote system name.
959 +
960 + 2. TIBExtract: No longer include comment header and COMMIT statement for empty
961 +   tables when data included in output.
962 +
963 + 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
964 +   and timing information to be written to stdout. This may be used to locate
965 +   performance bottlenecks.
966 +
967 + 4. SQLParser: only call "OnChanging" event handler when value is different.
968 +
969 + 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
970 +
971 + 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
972 +   that BindFields is called when the query is next activated. Avoids FieldName
973 +   not found error.
974 +
975 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
976 +   purpose and allows the programmer to define any action they want for Update, Insert
977 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
978 +   filtering of updates, or use of statements such as Grant or Revoke instead of
979 +   normal DML. See User Manual for more information.
980 +
981 + IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
982 +
983 + 1. TIBEvents: Fix uninitialised variable that could result in lost events.
984 +
985 + 2. TIBExtract: Added support for FB3 "USAGE" privilege.
986 +
987 + 3. TIBExtract: data formatted as Charset set "octets" is now output using
988 +   hexadecimal notation.
989 +
990 + 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
991 +   using a simple XML format.
992 +
993 + 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
994 +   grants to these objects.
995 +
996 + 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
997 +   dependency problems restoring complex databases.
998 +
999 + 7. TIBXScript: This component has been restructured to allow for the processing of
1000 +   embedded XML in INSERT statements and to support interactive sources in addition
1001 +   to non-interactive data sources such as files.
1002 +
1003 + 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
1004 +
1005 + 9. TIBXScript: ISQL compatiable Set statements are now supported:
1006 +   SET SQL DIALECT
1007 +   SET TERM
1008 +   SET AUTODDL
1009 +   SET BAIL
1010 +   SET ECHO
1011 +   SET COUNT
1012 +   SET STATS
1013 +   SET NAMES <character set>
1014 +
1015 + 10. IBVersion unit added to hold current IBX Version Number information.
1016 +
1017 + 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
1018 +    and domain definitions.
1019 +
1020 + 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
1021 +    fully supported.
1022 +
1023 + 13. TIBExtract: when a database dump includes data, the generator values are now also set.
1024 +
1025 + 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
1026 +
1027 + IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
1028 +
1029 + See also doc/IBX4LazarusGuide.pdf for important information on
1030 + upgrading to IBX2.
1031 +
1032 + 1. Size property of TIBStringField is now the width in characters of the field
1033 +   and not the byte length. This applies only to multi-byte character sets such
1034 +   as UTF8. The original approach aligned with TStringField. However, the TStringField
1035 +   code is not recognised as a bug and hence this change to align the behaviour.
1036 +   The TStringField change is expected in fpc 3.2.0.
1037 +
1038 + 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
1039 +   true (default) then Size property value saved in the lfm is ignored. Size is
1040 +   always set from the dynamic information read from the database. It is unclear
1041 +   why anyone would want to override this and set Size to false.
1042 +
1043 + 3. ibxscript: should now handle correctly a Case..End statement within a procedure
1044 +   block.
1045 +
1046 + 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
1047 +   exist when an attempt is made to connect to it (run time only) then an attempt
1048 +   is made to create the database.
1049 +
1050 + 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
1051 +   has been successfully created as a result of a call to CreateDatabase or when
1052 +   creating a database after it was found not to exist.
1053 +
1054 + 6.  DBControlGrid: a race condition could result in the wrong row image being
1055 +    written to the cache. This has been avoided by a trip round the message
1056 +    loop before rendering the row image.
1057 +
1058 + 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
1059 +    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
1060 +    known to risk corrupt rendering of row images when the control is first
1061 +    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
1062 +    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
1063 +
1064 + 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
1065 +    a TDateEdit control located on an editor panel.
1066 +
1067 + 9.  TIBExtract: brought up-to-date plus many bug fixes.
1068 +
1069 + 10. DBControlGrid: Removed memory leak when updating rows.
1070 +
1071 + 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.

1074 +
1075 + 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
1076 +   when target codepage is CP_NONE. This is a workaround for
1077 +   http://bugs.freepascal.org/view.php?id=30622.
1078 +
1079 + 2. DBLog option removed from TIBStatisticalService - not supported by server
1080 +   since Firebird 1.5.
1081 +
1082 + 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
1083 +   similar.
1084 +
1085 + 4. IBCodePage: updated mapping between codepages and character id.
1086 +
1087 + 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
1088 +   Firebird. Character sets with a char width of two are not UTF16.
1089 +
1090 + 6. Strings received from the database are now always transliterated into UTF8
1091 +   regardless of the database character set or connection character set. This
1092 +   is for compatibility with the LCL.
1093 +
1094 + IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
1095 +
1096 + 1. IBBlob: Defer reading of blob until read method called. This avoids having to
1097 +   read in an entire blob just to get the size of the blob. General performance
1098 +   improvement when opening datasets containing blobs.
1099 +
1100 + 2. Clearing a  Blob now sets the corresponding field's modified flag.
1101 +
1102 + 3. IBLookupCombo: When not performing auto-complete, original query sort order
1103 +   is now used.
1104 +
1105 + 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
1106 +   determined.
1107 +
1108 + 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
1109 +
1110 + 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
1111 +   lazarus 1.6.0
1112 +
1113 + 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
1114 +   compilation error.
1115 +
1116 + IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
1117 +
1118 + 1. No character set specified for connection: when a text blob is retrieved, the
1119 +  character set is determined by looking up the native character set using then
1120 +  Firebird API. Otherwise a text mode blob is assumed to have the same character
1121 +  set as the connection.
1122 +
1123 + 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
1124 +   for Login Dialog returing a change to the database path.
1125 +
1126 + 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
1127 +   to be changed from that given in the TIBDatabase/TIBServer component and for the
1128 +   entered value to be saved on a project specific basis (design time only).
1129 +
1130 + 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
1131 +   column fieldname. If they are the same then it is acts as a look up for the KeyValue
1132 +   Otherwise, it sets the column text to the selected ListField Value.
1133 +
1134 + 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
1135 +   column width.
1136 +
1137 + 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
1138 +   and a case insensitive search is requested.
1139 +
1140 + 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
1141 +   or column ListSource.
1142 +
1143 + 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
1144 +   unprepare) when closing and the text has not changed.
1145 +
1146 + 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
1147 +   Less likely to cause a cursor re-use error on Windows.
1148 +
1149 + 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
1150 +   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
1151 +
1152 + 11. TIBTreeView: Guard against nil destination on record changed
1153 +
1154 + 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
1155 +    string type with the code page set to reflect the returned field encoding after
1156 +    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
1157 +    earlier versions.
1158 +
1159 + 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
1160 +    will now result in transliteration to the code page specified for the Firebird driver
1161 +    if the assigned string has a different code page. FPC 3.0.0 onwards only.
1162 +
1163 + 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
1164 +    is ignored and the lc_ctype value, when the database is opened, is set to align with
1165 +    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
1166 +    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
1167 +    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
1168 +    the GETACP is used to determine the Windows code page.
1169 +
1170 + 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
1171 +    name used as the lc_ctype when the database was opened. Only valid while the
1172 +    Database is connected.
1173 +
1174 + 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
1175 +    id that corresponds to the DefaultCharSetName.
1176 +
1177 + IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
1178 +
1179 + 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
1180 +   path is given and database attach fails due to access permission issues on the
1181 +   temp directory or security database, then the attach is retried with "localhost:"
1182 +   prefixing the databasename. This should avoid problems when the database has to
1183 +   be accessed by a local (e.g. classic) server and libfbembed is used.
1184 +
1185 + 2. Windows: revised search order for Firebird DLL:
1186 +     i.   The Firebird Embedded Server in the application Directory.
1187 +     ii.  If the FIREBIRD environment variable is set then the directory this
1188 +          points to is searched for the FB Client DLL and then then underlying
1189 +          "bin" directory.
1190 +     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
1191 +          is used to locate the Firebird installation directory and the underlying
1192 +          "bin" directory is searched for the FB Client DLL.
1193 +     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
1194 +          are searched for the FB Client DLL.
1195 +     v.   The PATH Environment variable is used to search for the FB Client DLL.
1196 +     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
1197 +
1198 + 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
1199 +   See doc/readme.scriptengine and example applications.
1200 +
1201 + 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
1202 +   simplify the use of the embedded firebird server on both Linux and Windows platforms.
1203 +   See dpc/readme.localdatabase and example applications.
1204 +
1205 + 5. IBDynamicGrid: Reordering on column header click should now also work for
1206 +   dynamic columns.
1207 +
1208 + 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
1209 +   between incrementing/decrementing the lock count and signalling the event.
1210 +
1211 + IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
1212 +
1213 + 1.3.2 was never formally released and only made available as beta copies.
1214 +
1215 + 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
1216 +
1217 + 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
1218 +
1219 + 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
1220 +
1221 + 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
1222 +   i.e. when it is a calculated field
1223 +
1224 + 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
1225 +   This problem was due to a race condition between recalculating row heights and
1226 +   determining which row was selected by the mouse click. The row height calculation
1227 +   is now deferred by an extra trip round the message loop allowing the row to
1228 +   be always calculated on the current grid layout rather than risking it being
1229 +   calculated on the grid layout after the expanded row has been shrunk.
1230 +
1231 + 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
1232 +   Windows.
1233 +
1234 + 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
1235 +   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
1236 +   to be determined at runtime. See doc/readme.charactersets.html.
1237 +
1238 + 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
1239 +   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
1240 +
1241 + 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
1242 +   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
1243 +   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
1244 +
1245 +   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
1246 +   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
1247 +   implies no truncation.
1248 +
1249 + 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
1250 +
1251 + 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
1252 +   (avoids "Not in Edit Mode" error).
1253 +
1254 + 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
1255 +
1256 + 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
1257 +    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
1258 +
1259 + 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
1260 +
1261 + 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
1262 +
1263 + 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
1264 +
1265 + 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
1266 +
1267 + IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
1268 +
1269 + 1.   OnCloseUp Event Handler added to TDBLookupProperties
1270 +
1271 + 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
1272 +     problem with row size when exception is called.
1273 +
1274 + 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
1275 +
1276 + 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
1277 +     in a TCustomComboBox and ignores return key if in a TCustomMemo
1278 +
1279 + 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
1280 +     keyed in i.e. when autocomplete not performed
1281 +
1282 + 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
1283 +     console mode applications with all LCL required functions (builtin dialogs and
1284 +     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
1285 +     not included in your project, IBX should compile and link with a console mode program.
1286 +     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
1287 +     console mode application or the IDE will automatically assume that your
1288 +     application is GUI based. Instead, you should include the ibexpressconsolemode package.
1289 +
1290 +     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
1291 +     to use the built in dialogs and cursor management. IBDialogs is
1292 +     included by default if "ibexpress" is in your project source's "uses" clause.
1293 +     This should be the case for all projects created through the IDE. This is why
1294 +     you do not want to add the ibexpress package to console mode applications. The
1295 +     ibexpressconsolemode package has been created to allow console mode programs
1296 +     to avoid adding LCL dependencies when using IBX, while still having the
1297 +     unit search paths set up correctly.
1298 +
1299 +     Existing users should check to ensure that the "ibexpress" unit is included in
1300 +     each project's source file (*.lpr).
1301 +
1302 +     You may find that in order for the IDE to recognise that ibexpressconsolemode
1303 +     exists, you have to first open the package in the IDE and then close it. This
1304 +     adds it to the most recently accessed packages list. To make it permanently
1305 +     available, add the package name to lazarus' staticpackages.inc file.
1306 +
1307 +         Thanks to Julio Jiménez for suggesting support of console mode.
1308 +
1309 + 7.   SQL Parser can now accept quoted strings that include new lines
1310 +
1311 + 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
1312 +     of text on start of edit. This is particularly useful when tabbing to a
1313 +     column and then inserting text.
1314 +
1315 + 9.   New Examples provided for IB Services and ISQLMonitor.
1316 +
1317 + 10. Fix error when writing to blob streams that recorded only the last buffer
1318 +    write in the blob stream. In most cases, this did not cause a problem as the
1319 +    IB Blob Stream is written in a single write. However, with the TDBImage, write
1320 +    of a graphic type prefix was lost which caused a problem when the image could
1321 +        not be automatically recognised.
1322 +
1323 + 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
1324 +    already open" errors due to random numbers used for the cursor name being identical.
1325 +
1326 + 12. IBTable: corrected error that could result in an "Index out of bounds" error
1327 +    when opening the table and the Primary Key is the last or only column in the
1328 +    table. Thanks to Rick Hoover for the fix.
1329 +
1330 + 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
1331 +    of "UTF-8", and update list of available database character sets. Existing
1332 +    users should check the current lc_ctype setting in their applications.
1333 +
1334 + IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
1335 +
1336 + 1.  Firebird Services: avoid List Index error when opening a service with an
1337 +    empty Params property.
1338 +
1339 + 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
1340 +    Link now set up in Loaded method - avoids occasional failure to apply
1341 +    SQL markup on initial open.
1342 +
1343 + 3.  "Employees" example performance improvements when scrolling.
1344 +
1345 + 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
1346 +    TFrame. Force recaching of selected frame to avoid GTK race (results in a
1347 +    random image cached).
1348 +
1349 + 5.  DBControlGrid: Should now react to changes in panel height at run time.
1350 +
1351 + 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
1352 +    even when further rows exist.
1353 +
1354 + 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
1355 +    always be derived from panel height and setting this property can cause confusion.
1356 +    Note for existing projects: to avoid a missing property error at run time,
1357 +    each form using the DBControlGrid must be opened, updated and saved in the IDE
1358 +    in order to remove the property value from the lfm.
1359 +
1360 +
1361 + IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
1362 +
1363 + 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
1364 +    call Prepare before setting parameter values.
1365 +
1366 + 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
1367 +
1368 + 3.  Code tidyup and more robust handling of dsql information result vector.
1369 +
1370 + 4.  Support for centralised handling of transaction status changes. TIBTransaction
1371 +    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
1372 +    and "AfterExecQuery". The first three are called after the same event is called
1373 +    for an IBCustomDataSet descendent using the Transaction. The fourth is called
1374 +    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
1375 +    enable monitoring of transaction status changes for a given transaction to be
1376 +    handled in a single place. For example, when a change to the dataset occurs
1377 +    an indicator can be set that shows the user that in order to save changes,
1378 +    the transaction should be committed.  Rather than doing this per dataset, this
1379 +    can now be done per transaction.
1380 +
1381 + 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
1382 +    the dataset is scrolled. However, any changes to the current row are, by default,
1383 +    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
1384 +    have a new property "DataSetCloseAction" that adds automatic posting of changes
1385 +    on dataset close. If this property is set to dcDiscardChanges (default) then the
1386 +    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
1387 +    then IBX will attempt to post any unsaved changes before the dataset is closed
1388 +    (and after the BeforeClose event handler is called). The exception is when the
1389 +    dataset is being closed as a result of a transaction rollback. In this case,
1390 +    no action is taken and any unsaved  changes are discarded. This avoids both
1391 +    unnecessary overhead and the risk that a validation error may occur in the Post
1392 +    raising an exception and thereby preventing a rollback.
1393 +
1394 + 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
1395 +    In earlier versions, the Display Width was set to the maximum byte width rather than the character
1396 +    width. Display Widths are now corrected by dividing by the max byte width per character.
1397 +    For UTF8 character sets, the byte width is four and hence the Display Width will be
1398 +    the byte width divided by 4. The byte width of each character set is determined
1399 +    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
1400 +    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
1401 +
1402 + 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
1403 +
1404 + 8.  IBLookupComboEditBox: List should now always be restored to full list when the
1405 +    control loses focus. Default Key press default interval reduced to 200ms.
1406 +
1407 + 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
1408 +    when dataset rows are less than visible rows.
1409 +
1410 + 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1411 +    does not exist or DataSet is empty. More responsive on dataset open. New event
1412 +    OnRestorePosition. Column sort disabled if no header row.
1413 +
1414 + 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1415 +    while dataset state is dsInsert. Avoids posting errors.
1416 +
1417 + 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1418 +    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1419 +
1420 + 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1421 +
1422 + 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1423 +    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1424 +    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1425 +    always "posts" the current record regardless or whether or not it may be more appropriate
1426 +    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1427 +    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1428 +    as the first action of the "Post" method and allows the handler to convert the Post
1429 +    into a Cancel if that is the appropriate action on moving to a different row. This is
1430 +    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1431 +    raised here, but it may still be more appropriate to validate a post and signal
1432 +    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1433 +
1434 + 15. On Unix derived systems, the Firebird library name can now be given as a colon
1435 +    separated list. Each library name on the list is tried in turn, in left to right
1436 +    order with the first found being used as the firebird library. By default, on Linux,
1437 +    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1438 +    overidden by the FBLIB environment variable or the OnGetLibraryName function.
1439 +
1440 +    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1441 +    then it will still attempt to access the database via the Firebird Server and will
1442 +    require a username and password. If only the pathname is given, then the username
1443 +    and password should be omitted and the unix file permissions are used to grant
1444 +    access.
1445 +
1446 + IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1447 +
1448 + 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1449 +    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1450 +    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1451 +    corresponds to a row of the linked DataSource. Any data aware control on the
1452 +    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1453 +
1454 + 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1455 +   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1456 +   takes place during database access. This may be useful when there are performance issues with
1457 +   the change of cursor. Setting the property to false suppresses the change of cursor.
1458 +
1459 + 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1460 +   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1461 +   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1462 +   making all changes permanent immediately rather than when the transaction is explicitly
1463 +   committed.
1464 +
1465 + 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1466 +   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
1467 +
1468 + IBX Change Log  version      (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
1469 +
1470 + Development version only.
1471 +
1472 + IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1473 +
1474 + 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1475 +   This is typically used during an "OnBeforeOpen" event handler to manipulate the
1476 +   "Where" and "Having" clauses to implement user specified filters of arbitrary
1477 +   complexity.
1478 +
1479 + 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1480 +   three new data aware controls dependent on IBX and which make use of the SQL Parser.
1481 +   These are:
1482 +
1483 +   - TIBLookupComboEditBox
1484 +   - TIBDynamicGrid
1485 +   - TIBTreeview
1486 +
1487 +   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1488 +   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1489 +   to revise the available list and restrict it to items that are prefixed by the
1490 +   typed text (either case sensitive or case insensitive). Autoinsert allows a
1491 +   newly typed entry to be added to the list dataset and included in the available
1492 +   list items.
1493 +
1494 +   TIBDynamicGrid is a TDBGrid descendent that provides for:
1495 +   - automatic resizing of selected columns to fill the available row length
1496 +   - automatic positioning and sizing of a "totals" control, typically at the
1497 +     column footer, on a per column basis.
1498 +   - DataSet resorting on header row click, sorting the dataset by the selected column.
1499 +     A second click on the same header cell reversed the sort order.
1500 +   - Support for a "Panel Editor". That is on clicking the indicator column, the row
1501 +     is automatically expanded and a panel superimposed on it. The panel can have any
1502 +     number of child controls, typically data aware controls with the same datasource
1503 +     as the grid allowing for editing of additional fields and more complex editors.
1504 +   - Reselection of the same row following resorting.
1505 +   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1506 +     Its properties are specified on a per column basis and allows for one or more
1507 +     columns to have their values selected from a list provided by a dataset.
1508 +     Autocomplete and autoinsert are also available. The existing picklist editor
1509 +     is unaffected by the extension.
1510 +
1511 +   TIBTreeView is a data aware TCustomTreeView.
1512 +
1513 + 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1514 +   zero scale will no longer return an error. An Int64 will be returned instead.
1515 +
1516 + 4. TIBTransaction now has events for Before and After Transaction End and a new function
1517 +   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1518 +
1519 + 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1520 +   repeated multiple times.
1521 +
1522 + 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1523 +   check used to get in the way of using Stored Procedures, and "Update or Insert"
1524 +   statements.
1525 +
1526 + 7. Insert, Modify and Delete property Editors now support Query Generation from
1527 +   Stored Procedures.
1528 +
1529 + 8. Three new examples illustrate the use of the new IB Controls
1530 +
1531 +
1532 + IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1533 +
1534 + 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1535 +   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1536 +   Gabor Boros for reporting this problem and for testing the improvements).
1537 +
1538 + 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1539 +   See readme.field+param.names in the doc folder.
1540 +
1541 + 3. IBX SQL Editors will now automatically add double quotes around column names when the database
1542 +   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1543 +
1544 + 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1545 +
1546 + 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1547 +   actions.
1548 +
1549 + 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1550 +   thanks to Yuriy Kopnin for pointing this out).
1551 +
1552 + 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1553 +
1554 + 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1555 +   for both fields and parameter setting.
1556 +
1557 + 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1558 +   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1559 +
1560 + 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1561 +    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1562 +
1563 + 11. TIBTable now has a property editor for "MasterFields"
1564 +
1565 + 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1566 +    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1567 +
1568 + 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1569 +    of settings is unrecognised. Selecting this radio button has no effect on the settings.
1570 +

1572 + IBX Change Log  version                 (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
1573 +
1574 + 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1575 +
1576 + IBX Change Log  version          (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1577 +
1578 + 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1579 +   it is null. This allows for alternative user defined setting of the generator
1580 +
1581 +   Many thanks to Julio Jiménez for this fix
1582 +
1583 + 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1584 +   and suggests that the user may have forgotten to install it.
1585 +
1586 + IBX Change Log  version         (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1587 +
1588 + 1. Conditional compilation used to limit registration of TIntegerField to
1589 +   Lazarus versions less than 1.1
1590 +
1591 + 2. When a database connection is created, character set is now by default set
1592 +   to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1593 +   1250 to 1254.
1594 +
1595 +
1596 + IBX Change Log  version     (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
1597 +
1598 + 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1599 +
1600 +
1601 + IBX Change Log  version    (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1602 +
1603 + 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1604 +   Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1605 +
1606 + 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1607 +   package is changed to do this (which it should do).
1608 +
1609 + IBX Change Log  version (1.0-0)  Sat, 28 Apr 2012 16:43:00 +0100
1610 +
1611 + 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1612 +
1613 + 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1614 +
1615 + 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1616 +
1617 + 4. Property editors should now correctly resize.
1618 +
1619 + 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1620 +   (restored original functionality)
1621 +
1622 + 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1623 +   library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
