1 < IBX Change Log  version                                   (2.1-1) Fri, 12 Jan 2018 10:13:29 +0000
1 > FBINTF Change Log  version          (1.1-6 Build 12214) Fri, 17 Jul 2020 23:10:11 +0100
2  
3 < 1. IBExtract: Identity columns - add addition check for null column for generator name.
3 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
4 >   with a Firebrid 3 client library.
5  
6 < 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
7 <   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
8 <   information). Values returned as a result of executing an Insert or Update statement
9 <   replace existing values in the current row for each corresponding column.
6 > 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
7 >    If a client library path is not explicitly provided and the FIREBIRD environment
8 >    variable is set then the directory given by this variable and any 'lib' subdirectory
9 >    are searched for the Firebird client library. Only if none is found, is the default
10 >    client library used.
11  
12 < 3. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
11 <   When InsertSQL is generated, the Identity columns are not included in the list of values to
12 <   be inserted. A RETURNING clause is added to the insert statement to return the value of
13 <   each Identity column after the insert is executed.
12 > 3.  IUtil.FormatStatus now used to format error messages when using new API
13  
14 < 4. TIBGenerator: small performance improvement by not preparing query each time
16 <   a new number is generated.
14 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
15  
16 < 5. TIBSQL: Free resources when transaction changed.
16 > 5.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
17 >    returned using GetAsString and the string codepage is UTF8, the string is truncated so
18 >    that the byte length corresponds to the number of characters specified for the column.
19 >    SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
20 >    correct behaviour but may affect some implementations that relied upon automatic
21 >    trimming of trailing white space.
22  
23 < 6. Property editor will now sync table name to a System Table when "Include System
24 <   Tables" is selected and the query is for a System Table.
23 > 6.  New IFirebirdAPI Calls:
24 >      function GetClientMajor: integer;
25 >      function GetClientMinor: integer;
26  
23 7. Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
24   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
25   Insert..Returning clause.
27  
28 < 8. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
28 <   values are no longer converted to milliseconds from TDateTime and then back again
29 <   the TDateTime (the TDataset approach).
28 > FBINTF Change Log  version          (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +0100
29  
30 < IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
30 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
31 >   case sensitive
32  
33 < 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
34 <   changes.
33 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
34  
35 < 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
36 <   Bug could result in truncated multi-byte character set values.
35 > 3. New API Calls:
36 >        IColumnMetaData.GetStatement
37 >        IColumnMetaData.GetTransaction
38 >        ISQLData.GetStrLength
39 >        IResults.GetStatement
40 >        IAttachment.OpenBlob (using Blob metadata)
41 >        IAttachment.OpenArray (using array metadata)
42  
43 < 3. Changes consequential on moving fbintf character set utility functions from
40 <   IFirebirdAPI to IAttachment.
43 > 4. FBMessages: removal of unused messages
44  
45 < 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
45 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
46  
47 < 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
45 <   results in autocomplete ignoring prefix text.
47 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
48  
49 < 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
48 <   entering a new name into the text box.
49 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
50  
51 < 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
52 <   Firebird rather than recomputing it.
51 > 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
52 >   where the second character of the parameter name is a numeric.
53  
54 < 8. Property Editor positioning tidy up: All IBX Property editors should now be
55 <   screen centre. Previously some were "poDesigned" which may be inappropriate
56 <   for multi monitor desktops.
54 > 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
55 >   This returns the isc_version connection information as one or more lines.
56 >   This is the same information as returned by isql with the -z option.
57  
58 < 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
58 > 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
59 >   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
60 >   compiler option then the Firebird 3 API is no longer compiled in.
61  
62 < 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
60 <    a transaction and always reset the object.
62 > 4. IColumnMetaData: new method.
63  
64 < 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
64 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
65 >                        dfDateTime,   {SQL DATETIME}
66 >                        dfTime);
67  
68 < 13. TIBXScript: Allow for override of database filename in Create Database statements.
68 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
69  
70 < 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
71 <    to a gbak format archive.
70 >   This returns the max. number of characters returned by the "AsString" method
71 >   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
72  
73 < 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
73 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
74 >     CaseSensitiveParams: boolean = false
75  
76 < 16. IBLocaldb: Drop database if error creating an empty database.
76 >   If this argument is set to true then SQL parameter names are assumed to be case
77 >   sensitive and must be referenced (using ISQLParams.ByName) using the case
78 >   sensitive name.
79  
80 < 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
81 <    unless selected node not in current dataset.
80 > 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
81 >   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
82 >   .AsCurrency) and then subsequently to update the value to a non-numeric string
83 >   using .AsString.
84  
76 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
77    to TIBCustomService, and IBlocalDB code tidy up.
85  
79 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
80    behaviour due to uninitialised variable.
86  
87 < 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
83 <    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
87 > FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
88  
89 < 21. IBSQL: When Database changed ensure that all resources are freed.
89 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
90  
91 < 22. IBCustomDataset: When database changed ensure that queries an unprepared.
91 > 2. Restrict IsMultiThread check to Unix only for compatibility with
92 >   https://bugs.freepascal.org/view.php?id=30535
93  
94 < 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
95 <    * Line Wrap on SQL Token boundaries (on user command)
96 <    * auto-complete table names in drop down list of table names
92 <    * Double click on tablename or field name adds to SQL text
94 > 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
95 >   named parameters and is intended to avoid problems with (e.g.) Execute Block
96 >   and processing internal parameters as statement parameters.
97  
98 < 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
98 > 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
99 >   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
100  
101 < 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
97 <    TVariantArray. Seems to avoid memory corruption in Windows (probably a
98 <    workaround for a problem in fpc 3.0.4 win64).
101 > 5. New function added to IB.pas
102  
103 < 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
103 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
104  
105 < 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
105 >   This allows a Firebird Library to be loaded from an explicit path. use the
106 >   IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
107 >   the library. It is possible to load Firebird libraries from different locations
108 >   simultaneously, each with a distinct IFirebirdAPI.
109  
110 < IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
110 > FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
111  
112 < 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
113 <   include remote system name.
112 > 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
113 >   program compiled with -CR command line switch.
114  
115 < 2. TIBExtract: No longer include comment header and COMMIT statement for empty
116 <   tables when data included in output.
115 > 2. IServiceManager additions (informational):
116 >    function getProtocol: TProtocol;
117 >    function getPortNo: AnsiString;
118  
119 < 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
120 <   and timing information to be written to stdout. This may be used to locate
121 <   performance bottlenecks.
119 > 3. IServiceManager improved error handling. Interfaces changed:
120 >    function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
121 >    function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
122 >    function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
123  
124 < 4. SQLParser: only call "OnChanging" event handler when value is different.
124 > 4. IAttachment addition (informational)
125 >    function GetSecurityDatabase: AnsiString;
126  
127 < 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
127 > 5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
128 >   thus now returns accumulated stats for a select statement from opening a cursor
129 >   up to the last fetch.
130  
131 < 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
132 <   that BindFields is called when the query is next activated. Avoids FieldName
122 <   not found error.
131 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
132 >   the problem.
133  
134 < 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
135 <   purpose and allows the programmer to define any action they want for Update, Insert
126 <   or Delete. This may be complex SQL (similar to a Trigger), application specific
127 <   filtering of updates, or use of statements such as Grant or Revoke instead of
128 <   normal DML. See User Manual for more information.
134 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
135 >   replaces deprecated "comp" type.
136  
137 < IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
137 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
138  
139 < 1. TIBEvents: Fix uninitialised variable that could result in lost events.
139 > 11. URL Connection Strings: inet4 and inet6 now recognised.
140  
141 < 2. TIBExtract: Added support for FB3 "USAGE" privilege.
141 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
142  
143 < 3. TIBExtract: data formatted as Charset set "octets" is now output using
137 <   hexadecimal notation.
143 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
144  
139 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
140   using a simple XML format.
145  
146 < 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
143 <   grants to these objects.
146 > FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
147  
148 < 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
146 <   dependency problems restoring complex databases.
148 > 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
149  
150 < 7. TIBXScript: This component has been restructured to allow for the processing of
151 <   embedded XML in INSERT statements and to support interactive sources in addition
152 <   to non-interactive data sources such as files.
150 > 2. IAttachment: add two new methods
151 >     function HasDefaultCharSet: boolean;
152 >     function GetDefaultCharSetID: integer;
153  
154 < 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
154 >   These return, respectively, true if a connection default character set was
155 >   specified and the character set id of the connection default character set.
156 >   The DefaultCharSetID is cached when the connection is opened and hence does not
157 >   require a database lookup.
158  
159 < 9. TIBXScript: ISQL compatiable Set statements are now supported:
155 <   SET SQL DIALECT
156 <   SET TERM
157 <   SET AUTODDL
158 <   SET BAIL
159 <   SET ECHO
160 <   SET COUNT
161 <   SET STATS
162 <   SET NAMES <character set>
159 > 3. Avoid exception when a text blob is a stored procedure parameter.
160  
161 < 10. IBVersion unit added to hold current IBX Version Number information.
161 > 4. Update test suite to include a test for a stored proc returning a text blob.
162  
163 < 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
164 <    and domain definitions.
163 > 5. IAttachment: add
164 >      function GetRemoteProtocol: AnsiString;
165 >      function GetODSMajorVersion: integer;
166 >      function GetODSMinorVersion: integer;
167 >      function GetAuthenticationMethod: AnsiString;
168  
169 < 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
170 <    fully supported.
169 >   These results are cached when the connection is opened and hence do not
170 >   require a database lookup.
171  
172 < 13. TIBExtract: when a database dump includes data, the generator values are now also set.
172 > 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
173 >   connect string used to create/connect to the database.
174  
175 < 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
175 > 7. IAttachment: Create Database using SQL statement. The username and password
176 >   are now extracted and used to populate a DPB made available via IAttachment.getDPB.
177 >   It is now possible to use IAttachment disconnect/connect to reconnect to
178 >   a database for which the initial connection was established by a create
179 >   database sql statement. Available in FPC only.
180  
181 < IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
181 > 8. Update Test 1 to test 5, 6 and 7 above.
182  
183 < See also doc/IBX4LazarusGuide.pdf for important information on
179 < upgrading to IBX2.
183 > 9. IBUtils code tidy up.
184  
185 < 1. Size property of TIBStringField is now the width in characters of the field
186 <   and not the byte length. This applies only to multi-byte character sets such
187 <   as UTF8. The original approach aligned with TStringField. However, the TStringField
188 <   code is not recognised as a bug and hence this change to align the behaviour.
185 <   The TStringField change is expected in fpc 3.2.0.
185 > 10. Parameter Block interfaces "find" method. As documented, this should have
186 >   returned a nil interface when the item could not be found. Instead, an empty
187 >   interface item was returned. "Find" now works as documented and will return
188 >   a nil interface if the item cannot be found.
189  
190 < 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
188 <   true (default) then Size property value saved in the lfm is ignored. Size is
189 <   always set from the dynamic information read from the database. It is unclear
190 <   why anyone would want to override this and set Size to false.
190 > 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
191  
192 < 3. ibxscript: should now handle correctly a Case..End statement within a procedure
193 <   block.
192 > 12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
193 >    requests with additional parameters. This is to enable support for fb_info_page_contents
194 >    (return of page contents). Response to fb_info_page_contents returned as
195 >    a string with code page CP_NONE.
196  
197 < 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
198 <   exist when an attempt is made to connect to it (run time only) then an attempt
197 <   is made to create the database.
197 > 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
198 >    test suite updated.
199  
200 < 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
201 <   has been successfully created as a result of a call to CreateDatabase or when
201 <   creating a database after it was found not to exist.
200 > 14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
201 >    a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
202  
203 < 6.  DBControlGrid: a race condition could result in the wrong row image being
204 <    written to the cache. This has been avoided by a trip round the message
205 <    loop before rendering the row image.
203 > 15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
204 >    An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
205 >    default connection port to be specified.
206  
207 < 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
208 <    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
209 <    known to risk corrupt rendering of row images when the control is first
210 <    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
211 <    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
207 > FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
208  
209 < 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
210 <    a TDateEdit control located on an editor panel.
209 > 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
210 >   Scale is no longer ignored.
211  
212 < 9.  TIBExtract: brought up-to-date plus many bug fixes.
212 > 2. Fix issues with setting SQL Param values using SetAsString with Date values
213 >   not in locale format but which are recognised by Firebird. Date values that
214 >   cannot be converted to a string using Pascal library are now passed through
215 >   to Firebird as Text Strings.
216  
217 < 10. DBControlGrid: Removed memory leak when updating rows.
217 > 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
218 >   UTF8 and not UNICODE_FSS.
219  
220 < 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
220 > 4. Charset ID problem. When using Firebird 3, with no default database character set
221 >   and a column has a non-default collation specified, an incorrect character set
222 >   id was being reported that could result in a 'division by zero' error when
223 >   used by IBX. This has now been fixed.
224  
225 < IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
225 > 5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
226 >   CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
227 >   the character sets supported can be updated on a per database basis. That is
228 >   it is possible to add a (Firebird) user defined character set to a database.
229  
230 < 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
231 <   when target codepage is CP_NONE. This is a workaround for
226 <   http://bugs.freepascal.org/view.php?id=30622.
230 > 6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
231 >   set supported by Firebird with the API.
232  
233 < 2. DBLog option removed from TIBStatisticalService - not supported by server
234 <   since Firebird 1.5.
233 > 7. Add missing isc_info_db_read_only to list of decoded Database Information items
234 >   in FBOutputBlock.pas and update test suite to include this item.
235  
236 < 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
232 <   similar.
236 > 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
237  
238 < 4. IBCodePage: updated mapping between codepages and character id.
238 > 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
239 >   library or finding it by disk location, the PATH environment variable is now also set to
240 >   include the FIREBIRD directory. This is to ensure that the correct dlls in the
241 >   firebird client library dependencies are loaded.
242  
243 < 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
237 <   Firebird. Character sets with a char width of two are not UTF16.
243 > 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
244  
245 < 6. Strings received from the database are now always transliterated into UTF8
240 <   regardless of the database character set or connection character set. This
241 <   is for compatibility with the LCL.
245 > 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.

247 < IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
247 > 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
248  
249 < 1. IBBlob: Defer reading of blob until read method called. This avoids having to
250 <   read in an entire blob just to get the size of the blob. General performance
251 <   improvement when opening datasets containing blobs.
249 > 13. FB30Statement: A check has been added to ensure that all SQL Parameters
250 >    have been given a value (including NULL). Previously, failing to set the
251 >    value of an SQL Parameter could give rise to unpredictable results or
252 >    an SQLDA error.
253  
254 < 2. Clearing a  Blob now sets the corresponding field's modified flag.
254 > 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
255  
256 < 3. IBLookupCombo: When not performing auto-complete, original query sort order
257 <   is now used.
256 > 15. FBAttachment: Avoid string reference count error when processing an Ansistring
257 >    parameter in an array of const passed to IAttachment.OpenCursor, etc.
258  
259 < 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
260 <   determined.
259 > 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
260 >    of const passed to IAttachment.OpenCursor, etc.
261  
257 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
262  
263 < 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
260 <   lazarus 1.6.0
263 > FBINTF Change Log  version             (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
264  
265 < 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
263 <   compilation error.
265 > 1. Change syntax to Mode Delphi
266  
267 < IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
267 > 2. Change all uses of string type to explicit AnsiString in order to ensure
268 >   compatibility between Delphi and FPC.
269  
270 < 1. No character set specified for connection: when a text blob is retrieved, the
271 <  character set is determined by looking up the native character set using then
269 <  Firebird API. Otherwise a text mode blob is assumed to have the same character
270 <  set as the connection.
270 > 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
271 >   defined for each interface.
272  
273 < 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
273 <   for Login Dialog returing a change to the database path.
273 > 4. Generics syntax variations for Delphi added
274  
275 < 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
276 <   to be changed from that given in the TIBDatabase/TIBServer component and for the
277 <   entered value to be saved on a project specific basis (design time only).
275 > 5. PChar replaced with PByte expect where an actual string is being referenced,
276 >   where PAnsiChar is used instead.
277  
278 < 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
280 <   column fieldname. If they are the same then it is acts as a look up for the KeyValue
281 <   Otherwise, it sets the column text to the selected ListField Value.
278 > 6. Review of type definitions in IBExternals to ensure Delphi compatibility
279  
280 < 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
284 <   column width.
280 > 7. Testsuite updated for Delphi
281  
282 < 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
287 <   and a case insensitive search is requested.
282 > FBINTF Change Log  version            (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
283  
284 < 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
285 <   or column ListSource.
284 > 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
285 >   large blobs and the FB3 API.
286  
287 < 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
288 <   unprepare) when closing and the text has not changed.
287 > 2. Update Event Handling algorithm to avoid looping due to recreation of the
288 >   event block.
289  
290 < 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
296 <   Less likely to cause a cursor re-use error on Windows.
290 > 3. Avoid invalid XSQLDA error when the only parameter is updated to null
291  
292 < 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
293 <   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
292 > 4. Array Handling: fix problem with text arrays with character set none. When the
293 >   DB connection has a default character set (e.g. UTF8), an error is raised by
294 >   Firebird if the space allocated is not enough to allow for transliteration, even
295 >   though it is not required for character set none.
296  
297 < 11. TIBTreeView: Guard against nil destination on record changed
297 > 5. IBUtils: List of reserved words brought up-to-date
298  
299 < 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
304 <    string type with the code page set to reflect the returned field encoding after
305 <    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
306 <    earlier versions.
299 > 6. Add ISQL style performance statistics collection to IStatement
300  
301 < 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
302 <    will now result in transliteration to the code page specified for the Firebird driver
310 <    if the assigned string has a different code page. FPC 3.0.0 onwards only.
301 > 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
302 >   CREATE DATABASE statement.
303  
304 < 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
305 <    is ignored and the lc_ctype value, when the database is opened, is set to align with
314 <    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
315 <    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
316 <    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
317 <    the GETACP is used to determine the Windows code page.
304 > 8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in
305 >   an array dimension is not mistaken for a named parameter prefix.
306  
307 < 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
308 <    name used as the lc_ctype when the database was opened. Only valid while the
321 <    Database is connected.
307 > 9. Trim function no longer applied to result of GetAsString for SQL_TEXT
308 >   when Character set is octets. Avoids loss of non printable characters at start of string.
309  
310 < 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
311 <    id that corresponds to the DefaultCharSetName.
310 > 10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
311 >    statistics for the last action. Requires use of procedure IStatement.EnableStatistics
312 >    to enable stats gathering.
313  
314 < IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
314 > 11. API Version information added as constants to IB.pas
315  
316 < 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
329 <   path is given and database attach fails due to access permission issues on the
330 <   temp directory or security database, then the attach is retried with "localhost:"
331 <   prefixing the databasename. This should avoid problems when the database has to
332 <   be accessed by a local (e.g. classic) server and libfbembed is used.
316 > 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
317  
318 < 2. Windows: revised search order for Firebird DLL:
335 <     i.   The Firebird Embedded Server in the application Directory.
336 <     ii.  If the FIREBIRD environment variable is set then the directory this
337 <          points to is searched for the FB Client DLL and then then underlying
338 <          "bin" directory.
339 <     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
340 <          is used to locate the Firebird installation directory and the underlying
341 <          "bin" directory is searched for the FB Client DLL.
342 <     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
343 <          are searched for the FB Client DLL.
344 <     v.   The PATH Environment variable is used to search for the FB Client DLL.
345 <     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
318 > 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
319  
320 < 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
348 <   See doc/readme.scriptengine and example applications.
320 > FBINTF Change Log  version                                      (1.0-0) Tue, 06 Dec 2016 10:33:47 +0000
321  
322 < 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
351 <   simplify the use of the embedded firebird server on both Linux and Windows platforms.
352 <   See dpc/readme.localdatabase and example applications.
322 > 1. Initial Release
323  
354 5. IBDynamicGrid: Reordering on column header click should now also work for
355   dynamic columns.
356
357 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
358   between incrementing/decrementing the lock count and signalling the event.
359
360 IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
361
362 1.3.2 was never formally released and only made available as beta copies.
363
364 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
365
366 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
367
368 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
369
370 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
371   i.e. when it is a calculated field
372
373 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
374   This problem was due to a race condition between recalculating row heights and
375   determining which row was selected by the mouse click. The row height calculation
376   is now deferred by an extra trip round the message loop allowing the row to
377   be always calculated on the current grid layout rather than risking it being
378   calculated on the grid layout after the expanded row has been shrunk.
379
380 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
381   Windows.
382
383 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
384   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
385   to be determined at runtime. See doc/readme.charactersets.html.
386
387 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
388   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
389
390 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
391   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
392   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
393
394   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
395   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
396   implies no truncation.
397
398 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
399
400 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
401   (avoids "Not in Edit Mode" error).
402
403 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
404
405 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
406    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
407
408 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
409
410 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
411
412 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
413
414 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
415
416 IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
417
418 1.   OnCloseUp Event Handler added to TDBLookupProperties
419
420 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
421     problem with row size when exception is called.
422
423 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
424
425 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
426     in a TCustomComboBox and ignores return key if in a TCustomMemo
427
428 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
429     keyed in i.e. when autocomplete not performed
430
431 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
432     console mode applications with all LCL required functions (builtin dialogs and
433     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
434     not included in your project, IBX should compile and link with a console mode program.
435     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
436     console mode application or the IDE will automatically assume that your
437     application is GUI based. Instead, you should include the ibexpressconsolemode package.
438
439     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
440     to use the built in dialogs and cursor management. IBDialogs is
441     included by default if "ibexpress" is in your project source's "uses" clause.
442     This should be the case for all projects created through the IDE. This is why
443     you do not want to add the ibexpress package to console mode applications. The
444     ibexpressconsolemode package has been created to allow console mode programs
445     to avoid adding LCL dependencies when using IBX, while still having the
446     unit search paths set up correctly.
447
448     Existing users should check to ensure that the "ibexpress" unit is included in
449     each project's source file (*.lpr).
450
451     You may find that in order for the IDE to recognise that ibexpressconsolemode
452     exists, you have to first open the package in the IDE and then close it. This
453     adds it to the most recently accessed packages list. To make it permanently
454     available, add the package name to lazarus' staticpackages.inc file.
455
456         Thanks to Julio Jiménez for suggesting support of console mode.
457
458 7.   SQL Parser can now accept quoted strings that include new lines
459
460 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
461     of text on start of edit. This is particularly useful when tabbing to a
462     column and then inserting text.
463
464 9.   New Examples provided for IB Services and ISQLMonitor.
465
466 10. Fix error when writing to blob streams that recorded only the last buffer
467    write in the blob stream. In most cases, this did not cause a problem as the
468    IB Blob Stream is written in a single write. However, with the TDBImage, write
469    of a graphic type prefix was lost which caused a problem when the image could
470        not be automatically recognised.
471
472 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
473    already open" errors due to random numbers used for the cursor name being identical.
474
475 12. IBTable: corrected error that could result in an "Index out of bounds" error
476    when opening the table and the Primary Key is the last or only column in the
477    table. Thanks to Rick Hoover for the fix.
478
479 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
480    of "UTF-8", and update list of available database character sets. Existing
481    users should check the current lc_ctype setting in their applications.
482
483 IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
484
485 1.  Firebird Services: avoid List Index error when opening a service with an
486    empty Params property.
487
488 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
489    Link now set up in Loaded method - avoids occasional failure to apply
490    SQL markup on initial open.
491
492 3.  "Employees" example performance improvements when scrolling.
493
494 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
495    TFrame. Force recaching of selected frame to avoid GTK race (results in a
496    random image cached).
497
498 5.  DBControlGrid: Should now react to changes in panel height at run time.
499
500 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
501    even when further rows exist.
502
503 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
504    always be derived from panel height and setting this property can cause confusion.
505    Note for existing projects: to avoid a missing property error at run time,
506    each form using the DBControlGrid must be opened, updated and saved in the IDE
507    in order to remove the property value from the lfm.
508
509
510 IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
511
512 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
513    call Prepare before setting parameter values.
514
515 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
516
517 3.  Code tidyup and more robust handling of dsql information result vector.
518
519 4.  Support for centralised handling of transaction status changes. TIBTransaction
520    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
521    and "AfterExecQuery". The first three are called after the same event is called
522    for an IBCustomDataSet descendent using the Transaction. The fourth is called
523    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
524    enable monitoring of transaction status changes for a given transaction to be
525    handled in a single place. For example, when a change to the dataset occurs
526    an indicator can be set that shows the user that in order to save changes,
527    the transaction should be committed.  Rather than doing this per dataset, this
528    can now be done per transaction.
529
530 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
531    the dataset is scrolled. However, any changes to the current row are, by default,
532    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
533    have a new property "DataSetCloseAction" that adds automatic posting of changes
534    on dataset close. If this property is set to dcDiscardChanges (default) then the
535    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
536    then IBX will attempt to post any unsaved changes before the dataset is closed
537    (and after the BeforeClose event handler is called). The exception is when the
538    dataset is being closed as a result of a transaction rollback. In this case,
539    no action is taken and any unsaved  changes are discarded. This avoids both
540    unnecessary overhead and the risk that a validation error may occur in the Post
541    raising an exception and thereby preventing a rollback.
542
543 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
544    In earlier versions, the Display Width was set to the maximum byte width rather than the character
545    width. Display Widths are now corrected by dividing by the max byte width per character.
546    For UTF8 character sets, the byte width is four and hence the Display Width will be
547    the byte width divided by 4. The byte width of each character set is determined
548    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
549    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
550
551 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
552
553 8.  IBLookupComboEditBox: List should now always be restored to full list when the
554    control loses focus. Default Key press default interval reduced to 200ms.
555
556 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
557    when dataset rows are less than visible rows.
558
559 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
560    does not exist or DataSet is empty. More responsive on dataset open. New event
561    OnRestorePosition. Column sort disabled if no header row.
562
563 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
564    while dataset state is dsInsert. Avoids posting errors.
565
566 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
567    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
568
569 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
570
571 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
572    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
573    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
574    always "posts" the current record regardless or whether or not it may be more appropriate
575    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
576    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
577    as the first action of the "Post" method and allows the handler to convert the Post
578    into a Cancel if that is the appropriate action on moving to a different row. This is
579    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
580    raised here, but it may still be more appropriate to validate a post and signal
581    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
582
583 15. On Unix derived systems, the Firebird library name can now be given as a colon
584    separated list. Each library name on the list is tried in turn, in left to right
585    order with the first found being used as the firebird library. By default, on Linux,
586    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
587    overidden by the FBLIB environment variable or the OnGetLibraryName function.
588
589    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
590    then it will still attempt to access the database via the Firebird Server and will
591    require a username and password. If only the pathname is given, then the username
592    and password should be omitted and the unix file permissions are used to grant
593    access.

595 IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
596
597 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
598    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
599    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
600    corresponds to a row of the linked DataSource. Any data aware control on the
601    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
602
603 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
604   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
605   takes place during database access. This may be useful when there are performance issues with
606   the change of cursor. Setting the property to false suppresses the change of cursor.
607
608 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
609   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
610   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
611   making all changes permanent immediately rather than when the transaction is explicitly
612   committed.
613
614 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
615   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

621 IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
622
623 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
624   This is typically used during an "OnBeforeOpen" event handler to manipulate the
625   "Where" and "Having" clauses to implement user specified filters of arbitrary
626   complexity.
627
628 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
629   three new data aware controls dependent on IBX and which make use of the SQL Parser.
630   These are:
631
632   - TIBLookupComboEditBox
633   - TIBDynamicGrid
634   - TIBTreeview
635
636   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
637   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
638   to revise the available list and restrict it to items that are prefixed by the
639   typed text (either case sensitive or case insensitive). Autoinsert allows a
640   newly typed entry to be added to the list dataset and included in the available
641   list items.
642
643   TIBDynamicGrid is a TDBGrid descendent that provides for:
644   - automatic resizing of selected columns to fill the available row length
645   - automatic positioning and sizing of a "totals" control, typically at the
646     column footer, on a per column basis.
647   - DataSet resorting on header row click, sorting the dataset by the selected column.
648     A second click on the same header cell reversed the sort order.
649   - Support for a "Panel Editor". That is on clicking the indicator column, the row
650     is automatically expanded and a panel superimposed on it. The panel can have any
651     number of child controls, typically data aware controls with the same datasource
652     as the grid allowing for editing of additional fields and more complex editors.
653   - Reselection of the same row following resorting.
654   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
655     Its properties are specified on a per column basis and allows for one or more
656     columns to have their values selected from a list provided by a dataset.
657     Autocomplete and autoinsert are also available. The existing picklist editor
658     is unaffected by the extension.
659
660   TIBTreeView is a data aware TCustomTreeView.
661
662 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
663   zero scale will no longer return an error. An Int64 will be returned instead.
664
665 4. TIBTransaction now has events for Before and After Transaction End and a new function
666   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
667
668 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
669   repeated multiple times.
670
671 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
672   check used to get in the way of using Stored Procedures, and "Update or Insert"
673   statements.
674
675 7. Insert, Modify and Delete property Editors now support Query Generation from
676   Stored Procedures.
677
678 8. Three new examples illustrate the use of the new IB Controls
679
680
681 IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
682
683 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
684   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
685   Gabor Boros for reporting this problem and for testing the improvements).
686
687 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
688   See readme.field+param.names in the doc folder.
689
690 3. IBX SQL Editors will now automatically add double quotes around column names when the database
691   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
692
693 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
694
695 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
696   actions.
697
698 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
699   thanks to Yuriy Kopnin for pointing this out).
700
701 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
702
703 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
704   for both fields and parameter setting.
705
706 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
707   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
708
709 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
710    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
711
712 11. TIBTable now has a property editor for "MasterFields"
713
714 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
715    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
716
717 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
718    of settings is unrecognised. Selecting this radio button has no effect on the settings.
719

721 IBX Change Log  version                 (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
722
723 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
724
725 IBX Change Log  version          (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
726
727 1. In a TIBCustomDataset descendent, a generator now only sets the value when
728   it is null. This allows for alternative user defined setting of the generator
729
730   Many thanks to Julio Jiménez for this fix
731
732 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
733   and suggests that the user may have forgotten to install it.
734
735 IBX Change Log  version         (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
736
737 1. Conditional compilation used to limit registration of TIntegerField to
738   Lazarus versions less than 1.1
739
740 2. When a database connection is created, character set is now by default set
741   to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
742   1250 to 1254.
743
744
745 IBX Change Log  version     (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
746
747 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
748
749
750 IBX Change Log  version    (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
751
752 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
753   Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
754
755 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
756   package is changed to do this (which it should do).
757
758 IBX Change Log  version (1.0-0)  Sat, 28 Apr 2012 16:43:00 +0100
759
760 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
761
762 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
763
764 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
765
766 4. Property editors should now correctly resize.
767
768 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
769   (restored original functionality)
770
771 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
772   library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
