1 < IBX Change Log  version                                    (2.2-0) Mon, 15 Jan 2018 23:43:19 +0000
1 > FBINTF Change Log  version          (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +0100
2  
3 < 1. IBExtract: Identity columns - add additional check for null column for generator name.
3 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
4 >   case sensitive
5  
6 < 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
6 <   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
7 <   information). However, this is also a very useful mechanism for returning updated computed by
8 <   column values. 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. Single line SQL comments starting with '--' are now recognised by SQL Parser.
7  
8 <   Previously, if a dataset's select query included read only (computed by) fields then
9 <   an automatic row refresh was performed after an insert or update query had been processed,
10 <   irrespective of the setting of the "ForcedUpdates" property. This has changed such
11 <   that an automatic refresh is no longer performed if an insert or update query contains
12 <   a returning clause that updates one or more fields on the current row. A full row
13 <   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
14 <   field values and the select query contains read only fields. Use of Insert/update
18 <   returning should be significantly more efficient than excuting a refresh query.
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)
15  
16 <   This behaviour change is intended to be backwards compatible and there should be no need to change
21 <   existing programs, other than to improve performance by using the new capability.
16 > 4. FBMessages: removal of unused messages
17  
18 < 3. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
24 <   any Computed By or Identity Columns. The IBTables example has been updated to
25 <   illustrate the computation of the employee Full Name on update.
18 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
19  
20 < 4. TIBTable: The GeneratorField property is now published.
20 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
21  
22 < 5. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
30 <   When InsertSQL is generated, the Identity columns are not included in the list of values to
31 <   be inserted. A RETURNING clause is added to the insert statement to return the value of
32 <   each Identity column after the insert is executed.
22 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
23  
24 < 6. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
25 <   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
36 <   Insert..Returning clause.
24 > 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
25 >   where the second character of the parameter name is a numeric.
26  
27 < 7. TIBGenerator: small performance improvement by not preparing query each time
28 <   a new value is generated.
27 > 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.
30  
31 < 8. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
31 > 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
32 >   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
33 >   compiler option then the Firebird 3 API is no longer compiled in.
34  
35 < 9. Property editors will now sync table name to a System Table when "Include System
44 <   Tables" is selected and the query is for a System Table.
35 > 4. IColumnMetaData: new method.
36  
37 < 10. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
38 <    values are no longer converted to milliseconds from TDateTime and then back again
39 <    to TDateTime (the conversion to milliseconds is the default TDataset approach).
37 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
38 >                        dfDateTime,   {SQL DATETIME}
39 >                        dfTime);
40  
41 < 11. Property Editors handling of Stored Procedures.
51 <    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
52 <      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
53 <      query).
54 <    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
41 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
42  
43 < 12. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
44 <    can be used to select a package. If non-empty, the stored procedure name is
58 <    expected to be a stored procedure defined in the specified package and the
59 <    generated SQL will be as required for a stored procedure located in a package.
43 >   This returns the max. number of characters returned by the "AsString" method
44 >   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
45  
46 < 13. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
47 <    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
63 <    which a stored procedure can be selected. With no package name selected, non-package
64 <    stored procedures are listed.
46 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
47 >     CaseSensitiveParams: boolean = false
48  
49 +   If this argument is set to true then SQL parameter names are assumed to be case
50 +   sensitive and must be referenced (using ISQLParams.ByName) using the case
51 +   sensitive name.
52  
53 < IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
53 > 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
54 >   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
55 >   .AsCurrency) and then subsequently to update the value to a non-numeric string
56 >   using .AsString.
57  
69 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
70   changes.
58  
72 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
73   Bug could result in truncated multi-byte character set values.
59  
60 < 3. Changes consequential on moving fbintf character set utility functions from
76 <   IFirebirdAPI to IAttachment.
60 > FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
61  
62 < 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
62 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
63  
64 < 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
65 <   results in autocomplete ignoring prefix text.
64 > 2. Restrict IsMultiThread check to Unix only for compatibility with
65 >   https://bugs.freepascal.org/view.php?id=30535
66  
67 < 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
68 <   entering a new name into the text box.
67 > 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.
70  
71 < 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
72 <   Firebird rather than recomputing it.
71 > 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
72 >   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
73  
74 < 8. Property Editor positioning tidy up: All IBX Property editors should now be
90 <   screen centre. Previously some were "poDesigned" which may be inappropriate
91 <   for multi monitor desktops.
74 > 5. New function added to IB.pas
75  
76 < 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
76 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
77  
78 < 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
79 <    a transaction and always reset the object.
78 >   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.
82  
83 < 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
83 > FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
84  
85 < 13. TIBXScript: Allow for override of database filename in Create Database statements.
85 > 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
86 >   program compiled with -CR command line switch.
87  
88 < 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
89 <    to a gbak format archive.
88 > 2. IServiceManager additions (informational):
89 >    function getProtocol: TProtocol;
90 >    function getPortNo: AnsiString;
91  
92 < 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
92 > 3. IServiceManager improved error handling. Interfaces changed:
93 >    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;
96  
97 < 16. IBLocaldb: Drop database if error creating an empty database.
97 > 4. IAttachment addition (informational)
98 >    function GetSecurityDatabase: AnsiString;
99  
100 < 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
101 <    unless selected node not in current dataset.
100 > 5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
101 >   thus now returns accumulated stats for a select statement from opening a cursor
102 >   up to the last fetch.
103  
104 < 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
105 <    to TIBCustomService, and IBlocalDB code tidy up.
104 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
105 >   the problem.
106  
107 < 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
108 <    behaviour due to uninitialised variable.
107 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
108 >   replaces deprecated "comp" type.
109  
110 < 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
119 <    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
110 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
111  
112 < 21. IBSQL: When Database changed ensure that all resources are freed.
112 > 11. URL Connection Strings: inet4 and inet6 now recognised.
113  
114 < 22. IBCustomDataset: When database changed ensure that queries an unprepared.
114 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
115  
116 < 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
126 <    * Line Wrap on SQL Token boundaries (on user command)
127 <    * auto-complete table names in drop down list of table names
128 <    * Double click on tablename or field name adds to SQL text
116 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
117  
130 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
118  
119 < 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
133 <    TVariantArray. Seems to avoid memory corruption in Windows (probably a
134 <    workaround for a problem in fpc 3.0.4 win64).
119 > FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
120  
121 < 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
121 > 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
122  
123 < 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
123 > 2. IAttachment: add two new methods
124 >     function HasDefaultCharSet: boolean;
125 >     function GetDefaultCharSetID: integer;
126  
127 < IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
127 >   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.
131  
132 < 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
143 <   include remote system name.
132 > 3. Avoid exception when a text blob is a stored procedure parameter.
133  
134 < 2. TIBExtract: No longer include comment header and COMMIT statement for empty
146 <   tables when data included in output.
134 > 4. Update test suite to include a test for a stored proc returning a text blob.
135  
136 < 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
137 <   and timing information to be written to stdout. This may be used to locate
138 <   performance bottlenecks.
136 > 5. IAttachment: add
137 >      function GetRemoteProtocol: AnsiString;
138 >      function GetODSMajorVersion: integer;
139 >      function GetODSMinorVersion: integer;
140 >      function GetAuthenticationMethod: AnsiString;
141  
142 < 4. SQLParser: only call "OnChanging" event handler when value is different.
142 >   These results are cached when the connection is opened and hence do not
143 >   require a database lookup.
144  
145 < 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
145 > 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
146 >   connect string used to create/connect to the database.
147  
148 < 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
149 <   that BindFields is called when the query is next activated. Avoids FieldName
150 <   not found error.
148 > 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.
153  
154 < 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
161 <   purpose and allows the programmer to define any action they want for Update, Insert
162 <   or Delete. This may be complex SQL (similar to a Trigger), application specific
163 <   filtering of updates, or use of statements such as Grant or Revoke instead of
164 <   normal DML. See User Manual for more information.
154 > 8. Update Test 1 to test 5, 6 and 7 above.
155  
156 < IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
156 > 9. IBUtils code tidy up.
157  
158 < 1. TIBEvents: Fix uninitialised variable that could result in lost events.
158 > 10. Parameter Block interfaces "find" method. As documented, this should have
159 >   returned a nil interface when the item could not be found. Instead, an empty
160 >   interface item was returned. "Find" now works as documented and will return
161 >   a nil interface if the item cannot be found.
162  
163 < 2. TIBExtract: Added support for FB3 "USAGE" privilege.
163 > 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
164  
165 < 3. TIBExtract: data formatted as Charset set "octets" is now output using
166 <   hexadecimal notation.
165 > 12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
166 >    requests with additional parameters. This is to enable support for fb_info_page_contents
167 >    (return of page contents). Response to fb_info_page_contents returned as
168 >    a string with code page CP_NONE.
169  
170 < 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
171 <   using a simple XML format.
170 > 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
171 >    test suite updated.
172  
173 < 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
174 <   grants to these objects.
173 > 14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
174 >    a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
175  
176 < 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
177 <   dependency problems restoring complex databases.
176 > 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.
179  
180 < 7. TIBXScript: This component has been restructured to allow for the processing of
185 <   embedded XML in INSERT statements and to support interactive sources in addition
186 <   to non-interactive data sources such as files.
180 > FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
181  
182 < 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
182 > 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
183 >   Scale is no longer ignored.
184  
185 < 9. TIBXScript: ISQL compatiable Set statements are now supported:
186 <   SET SQL DIALECT
187 <   SET TERM
188 <   SET AUTODDL
194 <   SET BAIL
195 <   SET ECHO
196 <   SET COUNT
197 <   SET STATS
198 <   SET NAMES <character set>
185 > 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.
189  
190 < 10. IBVersion unit added to hold current IBX Version Number information.
190 > 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
191 >   UTF8 and not UNICODE_FSS.
192  
193 < 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
194 <    and domain definitions.
193 > 4. Charset ID problem. When using Firebird 3, with no default database character set
194 >   and a column has a non-default collation specified, an incorrect character set
195 >   id was being reported that could result in a 'division by zero' error when
196 >   used by IBX. This has now been fixed.
197  
198 < 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
199 <    fully supported.
198 > 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.
202  
203 < 13. TIBExtract: when a database dump includes data, the generator values are now also set.
203 > 6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
204 >   set supported by Firebird with the API.
205  
206 < 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
206 > 7. Add missing isc_info_db_read_only to list of decoded Database Information items
207 >   in FBOutputBlock.pas and update test suite to include this item.
208  
209 < IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
209 > 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
210  
211 < See also doc/IBX4LazarusGuide.pdf for important information on
212 < upgrading to IBX2.
211 > 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
212 >   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.
215  
216 < 1. Size property of TIBStringField is now the width in characters of the field
218 <   and not the byte length. This applies only to multi-byte character sets such
219 <   as UTF8. The original approach aligned with TStringField. However, the TStringField
220 <   code is not recognised as a bug and hence this change to align the behaviour.
221 <   The TStringField change is expected in fpc 3.2.0.
216 > 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
217  
218 < 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
224 <   true (default) then Size property value saved in the lfm is ignored. Size is
225 <   always set from the dynamic information read from the database. It is unclear
226 <   why anyone would want to override this and set Size to false.
218 > 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
219  
220 < 3. ibxscript: should now handle correctly a Case..End statement within a procedure
229 <   block.
220 > 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
221  
222 < 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
223 <   exist when an attempt is made to connect to it (run time only) then an attempt
224 <   is made to create the database.
222 > 13. FB30Statement: A check has been added to ensure that all SQL Parameters
223 >    have been given a value (including NULL). Previously, failing to set the
224 >    value of an SQL Parameter could give rise to unpredictable results or
225 >    an SQLDA error.
226  
227 < 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
236 <   has been successfully created as a result of a call to CreateDatabase or when
237 <   creating a database after it was found not to exist.
227 > 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
228  
229 < 6.  DBControlGrid: a race condition could result in the wrong row image being
230 <    written to the cache. This has been avoided by a trip round the message
241 <    loop before rendering the row image.
229 > 15. FBAttachment: Avoid string reference count error when processing an Ansistring
230 >    parameter in an array of const passed to IAttachment.OpenCursor, etc.
231  
232 < 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
233 <    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
245 <    known to risk corrupt rendering of row images when the control is first
246 <    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
247 <    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
232 > 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
233 >    of const passed to IAttachment.OpenCursor, etc.
234  
249 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
250    a TDateEdit control located on an editor panel.
235  
236 < 9.  TIBExtract: brought up-to-date plus many bug fixes.

238 < 10. DBControlGrid: Removed memory leak when updating rows.
238 > 1. Change syntax to Mode Delphi
239  
240 < 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
240 > 2. Change all uses of string type to explicit AnsiString in order to ensure

243 > 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
244 >   defined for each interface.
245  
246 < 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
261 <   when target codepage is CP_NONE. This is a workaround for
262 <   http://bugs.freepascal.org/view.php?id=30622.
246 > 4. Generics syntax variations for Delphi added
247  
248 < 2. DBLog option removed from TIBStatisticalService - not supported by server
249 <   since Firebird 1.5.
248 > 5. PChar replaced with PByte expect where an actual string is being referenced,
249 >   where PAnsiChar is used instead.
250  
251 < 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
268 <   similar.
251 > 6. Review of type definitions in IBExternals to ensure Delphi compatibility
252  
253 < 4. IBCodePage: updated mapping between codepages and character id.
253 > 7. Testsuite updated for Delphi
254  
255 < 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
273 <   Firebird. Character sets with a char width of two are not UTF16.

256  
257 < 6. Strings received from the database are now always transliterated into UTF8
258 <   regardless of the database character set or connection character set. This
277 <   is for compatibility with the LCL.
257 > 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
258 >   large blobs and the FB3 API.
259  
260 < IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
260 > 2. Update Event Handling algorithm to avoid looping due to recreation of the
261 >   event block.
262  
263 < 1. IBBlob: Defer reading of blob until read method called. This avoids having to
282 <   read in an entire blob just to get the size of the blob. General performance
283 <   improvement when opening datasets containing blobs.
263 > 3. Avoid invalid XSQLDA error when the only parameter is updated to null
264  
265 < 2. Clearing a  Blob now sets the corresponding field's modified flag.
265 > 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.
269  
270 < 3. IBLookupCombo: When not performing auto-complete, original query sort order
288 <   is now used.
270 > 5. IBUtils: List of reserved words brought up-to-date
271  
272 < 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
291 <   determined.
272 > 6. Add ISQL style performance statistics collection to IStatement
273  
274 < 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
274 > 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
275 >   CREATE DATABASE statement.
276  
277 < 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
278 <   lazarus 1.6.0

286  
287 < 1. No character set specified for connection: when a text blob is retrieved, the
304 <  character set is determined by looking up the native character set using then
305 <  Firebird API. Otherwise a text mode blob is assumed to have the same character
306 <  set as the connection.
287 > 11. API Version information added as constants to IB.pas
288  
289 < 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
309 <   for Login Dialog returing a change to the database path.
289 > 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
290  
291 < 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
312 <   to be changed from that given in the TIBDatabase/TIBServer component and for the

291 > 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
292  
293 < 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the

294  
295 < 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
320 <   column width.
295 > 1. Initial Release
296  
322 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
323   and a case insensitive search is requested.
324
325 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
326   or column ListSource.
327
328 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
329   unprepare) when closing and the text has not changed.
330
331 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
332   Less likely to cause a cursor re-use error on Windows.
333
334 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
335   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
336
337 11. TIBTreeView: Guard against nil destination on record changed
338
339 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
340    string type with the code page set to reflect the returned field encoding after
341    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
342    earlier versions.
343
344 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
345    will now result in transliteration to the code page specified for the Firebird driver
346    if the assigned string has a different code page. FPC 3.0.0 onwards only.
347
348 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
349    is ignored and the lc_ctype value, when the database is opened, is set to align with
350    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
351    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
352    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
353    the GETACP is used to determine the Windows code page.
354
355 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
356    name used as the lc_ctype when the database was opened. Only valid while the
357    Database is connected.
358
359 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
360    id that corresponds to the DefaultCharSetName.

362 IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
363
364 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
365   path is given and database attach fails due to access permission issues on the
366   temp directory or security database, then the attach is retried with "localhost:"
367   prefixing the databasename. This should avoid problems when the database has to
368   be accessed by a local (e.g. classic) server and libfbembed is used.
369
370 2. Windows: revised search order for Firebird DLL:
371     i.   The Firebird Embedded Server in the application Directory.
372     ii.  If the FIREBIRD environment variable is set then the directory this
373          points to is searched for the FB Client DLL and then then underlying
374          "bin" directory.
375     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
376          is used to locate the Firebird installation directory and the underlying
377          "bin" directory is searched for the FB Client DLL.
378     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
379          are searched for the FB Client DLL.
380     v.   The PATH Environment variable is used to search for the FB Client DLL.
381     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
382
383 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
384   See doc/readme.scriptengine and example applications.
385
386 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
387   simplify the use of the embedded firebird server on both Linux and Windows platforms.
388   See dpc/readme.localdatabase and example applications.
389
390 5. IBDynamicGrid: Reordering on column header click should now also work for
391   dynamic columns.
392
393 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
394   between incrementing/decrementing the lock count and signalling the event.

396 IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
397
398 1.3.2 was never formally released and only made available as beta copies.
399
400 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
401
402 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
403
404 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
405
406 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
407   i.e. when it is a calculated field
408
409 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
410   This problem was due to a race condition between recalculating row heights and
411   determining which row was selected by the mouse click. The row height calculation
412   is now deferred by an extra trip round the message loop allowing the row to
413   be always calculated on the current grid layout rather than risking it being
414   calculated on the grid layout after the expanded row has been shrunk.
415
416 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
417   Windows.
418
419 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
420   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
421   to be determined at runtime. See doc/readme.charactersets.html.
422
423 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
424   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
425
426 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
427   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
428   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
429
430   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
431   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
432   implies no truncation.
433
434 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
435
436 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
437   (avoids "Not in Edit Mode" error).
438
439 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
440
441 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
442    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
443
444 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
445
446 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
447
448 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
449
450 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
451
452 IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
453
454 1.   OnCloseUp Event Handler added to TDBLookupProperties
455
456 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
457     problem with row size when exception is called.
458
459 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
460
461 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
462     in a TCustomComboBox and ignores return key if in a TCustomMemo
463
464 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
465     keyed in i.e. when autocomplete not performed
466
467 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
468     console mode applications with all LCL required functions (builtin dialogs and
469     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
470     not included in your project, IBX should compile and link with a console mode program.
471     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
472     console mode application or the IDE will automatically assume that your
473     application is GUI based. Instead, you should include the ibexpressconsolemode package.
474
475     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
476     to use the built in dialogs and cursor management. IBDialogs is
477     included by default if "ibexpress" is in your project source's "uses" clause.
478     This should be the case for all projects created through the IDE. This is why
479     you do not want to add the ibexpress package to console mode applications. The
480     ibexpressconsolemode package has been created to allow console mode programs
481     to avoid adding LCL dependencies when using IBX, while still having the
482     unit search paths set up correctly.
483
484     Existing users should check to ensure that the "ibexpress" unit is included in
485     each project's source file (*.lpr).
486
487     You may find that in order for the IDE to recognise that ibexpressconsolemode
488     exists, you have to first open the package in the IDE and then close it. This
489     adds it to the most recently accessed packages list. To make it permanently
490     available, add the package name to lazarus' staticpackages.inc file.
491
492         Thanks to Julio Jiménez for suggesting support of console mode.
493
494 7.   SQL Parser can now accept quoted strings that include new lines
495
496 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
497     of text on start of edit. This is particularly useful when tabbing to a
498     column and then inserting text.
499
500 9.   New Examples provided for IB Services and ISQLMonitor.
501
502 10. Fix error when writing to blob streams that recorded only the last buffer
503    write in the blob stream. In most cases, this did not cause a problem as the
504    IB Blob Stream is written in a single write. However, with the TDBImage, write
505    of a graphic type prefix was lost which caused a problem when the image could
506        not be automatically recognised.
507
508 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
509    already open" errors due to random numbers used for the cursor name being identical.
510
511 12. IBTable: corrected error that could result in an "Index out of bounds" error
512    when opening the table and the Primary Key is the last or only column in the
513    table. Thanks to Rick Hoover for the fix.
514
515 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
516    of "UTF-8", and update list of available database character sets. Existing
517    users should check the current lc_ctype setting in their applications.
518
519 IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
520
521 1.  Firebird Services: avoid List Index error when opening a service with an
522    empty Params property.
523
524 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
525    Link now set up in Loaded method - avoids occasional failure to apply
526    SQL markup on initial open.
527
528 3.  "Employees" example performance improvements when scrolling.
529
530 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
531    TFrame. Force recaching of selected frame to avoid GTK race (results in a
532    random image cached).
533
534 5.  DBControlGrid: Should now react to changes in panel height at run time.
535
536 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
537    even when further rows exist.
538
539 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
540    always be derived from panel height and setting this property can cause confusion.
541    Note for existing projects: to avoid a missing property error at run time,
542    each form using the DBControlGrid must be opened, updated and saved in the IDE
543    in order to remove the property value from the lfm.
544
545
546 IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
547
548 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
549    call Prepare before setting parameter values.
550
551 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
552
553 3.  Code tidyup and more robust handling of dsql information result vector.
554
555 4.  Support for centralised handling of transaction status changes. TIBTransaction
556    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
557    and "AfterExecQuery". The first three are called after the same event is called
558    for an IBCustomDataSet descendent using the Transaction. The fourth is called
559    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
560    enable monitoring of transaction status changes for a given transaction to be
561    handled in a single place. For example, when a change to the dataset occurs
562    an indicator can be set that shows the user that in order to save changes,
563    the transaction should be committed.  Rather than doing this per dataset, this
564    can now be done per transaction.
565
566 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
567    the dataset is scrolled. However, any changes to the current row are, by default,
568    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
569    have a new property "DataSetCloseAction" that adds automatic posting of changes
570    on dataset close. If this property is set to dcDiscardChanges (default) then the
571    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
572    then IBX will attempt to post any unsaved changes before the dataset is closed
573    (and after the BeforeClose event handler is called). The exception is when the
574    dataset is being closed as a result of a transaction rollback. In this case,
575    no action is taken and any unsaved  changes are discarded. This avoids both
576    unnecessary overhead and the risk that a validation error may occur in the Post
577    raising an exception and thereby preventing a rollback.
578
579 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
580    In earlier versions, the Display Width was set to the maximum byte width rather than the character
581    width. Display Widths are now corrected by dividing by the max byte width per character.
582    For UTF8 character sets, the byte width is four and hence the Display Width will be
583    the byte width divided by 4. The byte width of each character set is determined
584    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
585    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
586
587 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
588
589 8.  IBLookupComboEditBox: List should now always be restored to full list when the
590    control loses focus. Default Key press default interval reduced to 200ms.
591
592 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
593    when dataset rows are less than visible rows.
594
595 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
596    does not exist or DataSet is empty. More responsive on dataset open. New event
597    OnRestorePosition. Column sort disabled if no header row.
598
599 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
600    while dataset state is dsInsert. Avoids posting errors.
601
602 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
603    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
604
605 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
606
607 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
608    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
609    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
610    always "posts" the current record regardless or whether or not it may be more appropriate
611    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
612    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
613    as the first action of the "Post" method and allows the handler to convert the Post
614    into a Cancel if that is the appropriate action on moving to a different row. This is
615    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
616    raised here, but it may still be more appropriate to validate a post and signal
617    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
618
619 15. On Unix derived systems, the Firebird library name can now be given as a colon
620    separated list. Each library name on the list is tried in turn, in left to right
621    order with the first found being used as the firebird library. By default, on Linux,
622    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
623    overidden by the FBLIB environment variable or the OnGetLibraryName function.
624
625    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
626    then it will still attempt to access the database via the Firebird Server and will
627    require a username and password. If only the pathname is given, then the username
628    and password should be omitted and the unix file permissions are used to grant
629    access.

631 IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
632
633 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
634    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
635    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
636    corresponds to a row of the linked DataSource. Any data aware control on the
637    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
638
639 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
640   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
641   takes place during database access. This may be useful when there are performance issues with
642   the change of cursor. Setting the property to false suppresses the change of cursor.
643
644 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
645   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
646   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
647   making all changes permanent immediately rather than when the transaction is explicitly
648   committed.
649
650 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
651   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

657 IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
658
659 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
660   This is typically used during an "OnBeforeOpen" event handler to manipulate the
661   "Where" and "Having" clauses to implement user specified filters of arbitrary
662   complexity.
663
664 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
665   three new data aware controls dependent on IBX and which make use of the SQL Parser.
666   These are:
667
668   - TIBLookupComboEditBox
669   - TIBDynamicGrid
670   - TIBTreeview
671
672   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
673   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
674   to revise the available list and restrict it to items that are prefixed by the
675   typed text (either case sensitive or case insensitive). Autoinsert allows a
676   newly typed entry to be added to the list dataset and included in the available
677   list items.
678
679   TIBDynamicGrid is a TDBGrid descendent that provides for:
680   - automatic resizing of selected columns to fill the available row length
681   - automatic positioning and sizing of a "totals" control, typically at the
682     column footer, on a per column basis.
683   - DataSet resorting on header row click, sorting the dataset by the selected column.
684     A second click on the same header cell reversed the sort order.
685   - Support for a "Panel Editor". That is on clicking the indicator column, the row
686     is automatically expanded and a panel superimposed on it. The panel can have any
687     number of child controls, typically data aware controls with the same datasource
688     as the grid allowing for editing of additional fields and more complex editors.
689   - Reselection of the same row following resorting.
690   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
691     Its properties are specified on a per column basis and allows for one or more
692     columns to have their values selected from a list provided by a dataset.
693     Autocomplete and autoinsert are also available. The existing picklist editor
694     is unaffected by the extension.
695
696   TIBTreeView is a data aware TCustomTreeView.
697
698 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
699   zero scale will no longer return an error. An Int64 will be returned instead.
700
701 4. TIBTransaction now has events for Before and After Transaction End and a new function
702   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
703
704 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
705   repeated multiple times.
706
707 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
708   check used to get in the way of using Stored Procedures, and "Update or Insert"
709   statements.
710
711 7. Insert, Modify and Delete property Editors now support Query Generation from
712   Stored Procedures.
713
714 8. Three new examples illustrate the use of the new IB Controls
715
716
717 IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
718
719 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
720   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
721   Gabor Boros for reporting this problem and for testing the improvements).
722
723 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
724   See readme.field+param.names in the doc folder.
725
726 3. IBX SQL Editors will now automatically add double quotes around column names when the database
727   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
728
729 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
730
731 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
732   actions.
733
734 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
735   thanks to Yuriy Kopnin for pointing this out).
736
737 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
738
739 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
740   for both fields and parameter setting.
741
742 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
743   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
744
745 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
746    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
747
748 11. TIBTable now has a property editor for "MasterFields"
749
750 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
751    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
752
753 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
754    of settings is unrecognised. Selecting this radio button has no effect on the settings.
755

757 IBX Change Log  version                 (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
758
759 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
760
761 IBX Change Log  version          (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
762
763 1. In a TIBCustomDataset descendent, a generator now only sets the value when
764   it is null. This allows for alternative user defined setting of the generator
765
766   Many thanks to Julio Jiménez for this fix
767
768 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
769   and suggests that the user may have forgotten to install it.
770
771 IBX Change Log  version         (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
772
773 1. Conditional compilation used to limit registration of TIntegerField to
774   Lazarus versions less than 1.1
775
776 2. When a database connection is created, character set is now by default set
777   to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
778   1250 to 1254.
779
780
781 IBX Change Log  version     (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
782
783 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
784
785
786 IBX Change Log  version    (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
787
788 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
789   Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
790
791 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
792   package is changed to do this (which it should do).
793
794 IBX Change Log  version (1.0-0)  Sat, 28 Apr 2012 16:43:00 +0100
795
796 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
797
798 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
799
800 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
801
802 4. Property editors should now correctly resize.
803
804 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
805   (restored original functionality)
806
807 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
808   library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
