1 < IBX Change Log  version                               (2.1-1) Fri, 05 Jan 2018 10:40:04 +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 < IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
14 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
15  
16 < 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
17 <   changes.
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 < 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
24 <   Bug could result in truncated multi-byte character set values.
23 > 6.  New IFirebirdAPI Calls:
24 >      function GetClientMajor: integer;
25 >      function GetClientMinor: integer;
26  
23 3. Changes consequential on moving fbintf character set utility functions from
24   IFirebirdAPI to IAttachment.
27  
28 < 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
28 > FBINTF Change Log  version          (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +0100
29  
30 < 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
31 <   results in autocomplete ignoring prefix text.
30 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
31 >   case sensitive
32  
33 < 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
32 <   entering a new name into the text box.
33 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
34  
35 < 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
36 <   Firebird rather than recomputing it.
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 < 8. Property Editor positioning tidy up: All IBX Property editors should now be
38 <   screen centre. Previously some were "poDesigned" which may be inappropriate
39 <   for multi monitor desktops.
43 > 4. FBMessages: removal of unused messages
44  
45 < 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
45 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
46  
47 < 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
44 <    a transaction and always reset the object.
47 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
48  
49 < 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
49 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
50  
51 < 13. TIBXScript: Allow for override of database filename in Create Database statements.
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 < 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
55 <    to a gbak format archive.
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 < 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
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 < 16. IBLocaldb: Drop database if error creating an empty database.
62 > 4. IColumnMetaData: new method.
63  
64 < 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
65 <    unless selected node not in current dataset.
64 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
65 >                        dfDateTime,   {SQL DATETIME}
66 >                        dfTime);
67  
68 < 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
61 <    to TIBCustomService, and IBlocalDB code tidy up.
68 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
69  
70 < 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
71 <    behaviour due to uninitialised variable.
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 < 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
74 <    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
73 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
74 >     CaseSensitiveParams: boolean = false
75  
76 < 21. IBSQL: When Database changed ensure that all resources are freed.
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 < 22. IBCustomDataset: When database changed ensure that queries an unprepared.
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  
73 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
74    * Line Wrap on SQL Token boundaries (on user command)
75    * auto-complete table names in drop down list of table names
76    * Double click on tablename or field name adds to SQL text
85  
78 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
86  
87 < 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
81 <    TVariantArray. Seems to avoid memory corruption in Windows (probably a
82 <    workaround for a problem in fpc 3.0.4 win64).
87 > FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
88  
89 < 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
89 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
90  
91 < 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
91 > 2. Restrict IsMultiThread check to Unix only for compatibility with
92 >   https://bugs.freepascal.org/view.php?id=30535
93  
94 < IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
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 < 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
99 <   include remote system name.
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 < 2. TIBExtract: No longer include comment header and COMMIT statement for empty
94 <   tables when data included in output.
101 > 5. New function added to IB.pas
102  
103 < 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
97 <   and timing information to be written to stdout. This may be used to locate
98 <   performance bottlenecks.
103 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
104  
105 < 4. SQLParser: only call "OnChanging" event handler when value is different.
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 < 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
110 > FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
111  
112 < 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
113 <   that BindFields is called when the query is next activated. Avoids FieldName
106 <   not found error.
112 > 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
113 >   program compiled with -CR command line switch.
114  
115 < 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
116 <   purpose and allows the programmer to define any action they want for Update, Insert
117 <   or Delete. This may be complex SQL (similar to a Trigger), application specific
111 <   filtering of updates, or use of statements such as Grant or Revoke instead of
112 <   normal DML. See User Manual for more information.
115 > 2. IServiceManager additions (informational):
116 >    function getProtocol: TProtocol;
117 >    function getPortNo: AnsiString;
118  
119 < IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
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 < 1. TIBEvents: Fix uninitialised variable that could result in lost events.
124 > 4. IAttachment addition (informational)
125 >    function GetSecurityDatabase: AnsiString;
126  
127 < 2. TIBExtract: Added support for FB3 "USAGE" privilege.
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 < 3. TIBExtract: data formatted as Charset set "octets" is now output using
132 <   hexadecimal notation.
131 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
132 >   the problem.
133  
134 < 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
135 <   using a simple XML format.
134 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
135 >   replaces deprecated "comp" type.
136  
137 < 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
127 <   grants to these objects.
137 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
138  
139 < 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
130 <   dependency problems restoring complex databases.
139 > 11. URL Connection Strings: inet4 and inet6 now recognised.
140  
141 < 7. TIBXScript: This component has been restructured to allow for the processing of
133 <   embedded XML in INSERT statements and to support interactive sources in addition
134 <   to non-interactive data sources such as files.
141 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
142  
143 < 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
143 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
144  
138 9. TIBXScript: ISQL compatiable Set statements are now supported:
139   SET SQL DIALECT
140   SET TERM
141   SET AUTODDL
142   SET BAIL
143   SET ECHO
144   SET COUNT
145   SET STATS
146   SET NAMES <character set>
145  
146 < 10. IBVersion unit added to hold current IBX Version Number information.
146 > FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
147  
148 < 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
151 <    and domain definitions.
148 > 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
149  
150 < 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
151 <    fully supported.
150 > 2. IAttachment: add two new methods
151 >     function HasDefaultCharSet: boolean;
152 >     function GetDefaultCharSetID: integer;
153  
154 < 13. TIBExtract: when a database dump includes data, the generator values are now also set.
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 < 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
159 > 3. Avoid exception when a text blob is a stored procedure parameter.
160  
161 < IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
161 > 4. Update test suite to include a test for a stored proc returning a text blob.
162  
163 < See also doc/IBX4LazarusGuide.pdf for important information on
164 < upgrading to IBX2.
163 > 5. IAttachment: add
164 >      function GetRemoteProtocol: AnsiString;
165 >      function GetODSMajorVersion: integer;
166 >      function GetODSMinorVersion: integer;
167 >      function GetAuthenticationMethod: AnsiString;
168  
169 < 1. Size property of TIBStringField is now the width in characters of the field
170 <   and not the byte length. This applies only to multi-byte character sets such
167 <   as UTF8. The original approach aligned with TStringField. However, the TStringField
168 <   code is not recognised as a bug and hence this change to align the behaviour.
169 <   The TStringField change is expected in fpc 3.2.0.
169 >   These results are cached when the connection is opened and hence do not
170 >   require a database lookup.
171  
172 < 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
173 <   true (default) then Size property value saved in the lfm is ignored. Size is
173 <   always set from the dynamic information read from the database. It is unclear
174 <   why anyone would want to override this and set Size to false.
172 > 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
173 >   connect string used to create/connect to the database.
174  
175 < 3. ibxscript: should now handle correctly a Case..End statement within a procedure
176 <   block.
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 < 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
180 <   exist when an attempt is made to connect to it (run time only) then an attempt
181 <   is made to create the database.
181 > 8. Update Test 1 to test 5, 6 and 7 above.
182  
183 < 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
184 <   has been successfully created as a result of a call to CreateDatabase or when
185 <   creating a database after it was found not to exist.
183 > 9. IBUtils code tidy up.
184  
185 < 6.  DBControlGrid: a race condition could result in the wrong row image being
186 <    written to the cache. This has been avoided by a trip round the message
187 <    loop before rendering the row image.
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 < 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
192 <    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
193 <    known to risk corrupt rendering of row images when the control is first
194 <    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
195 <    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
190 > 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
191  
192 < 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
193 <    a TDateEdit control located on an editor panel.
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 < 9.  TIBExtract: brought up-to-date plus many bug fixes.
197 > 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
198 >    test suite updated.
199  
200 < 10. DBControlGrid: Removed memory leak when updating rows.
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 < 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
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 < IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
207 > FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
208  
209 < 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
210 <   when target codepage is CP_NONE. This is a workaround for
210 <   http://bugs.freepascal.org/view.php?id=30622.
209 > 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
210 >   Scale is no longer ignored.
211  
212 < 2. DBLog option removed from TIBStatisticalService - not supported by server
213 <   since Firebird 1.5.
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 < 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
218 <   similar.
217 > 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
218 >   UTF8 and not UNICODE_FSS.
219  
220 < 4. IBCodePage: updated mapping between codepages and character id.
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 < 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
226 <   Firebird. Character sets with a char width of two are not UTF16.
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 < 6. Strings received from the database are now always transliterated into UTF8
231 <   regardless of the database character set or connection character set. This
225 <   is for compatibility with the LCL.
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 < IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
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 < 1. IBBlob: Defer reading of blob until read method called. This avoids having to
230 <   read in an entire blob just to get the size of the blob. General performance
231 <   improvement when opening datasets containing blobs.
236 > 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
237  
238 < 2. Clearing a  Blob now sets the corresponding field's modified flag.
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

283  
284 < 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
285 <    string type with the code page set to reflect the returned field encoding after
289 <    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
290 <    earlier versions.
284 > 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with

286  
287 < 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
288 <    will now result in transliteration to the code page specified for the Firebird driver
294 <    if the assigned string has a different code page. FPC 3.0.0 onwards only.
287 > 2. Update Event Handling algorithm to avoid looping due to recreation of the
288 >   event block.
289  
290 < 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
297 <    is ignored and the lc_ctype value, when the database is opened, is set to align with
298 <    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
299 <    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
300 <    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
301 <    the GETACP is used to determine the Windows code page.
290 > 3. Avoid invalid XSQLDA error when the only parameter is updated to null
291  
292 < 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
293 <    name used as the lc_ctype when the database was opened. Only valid while the
294 <    Database is connected.
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 < 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
308 <    id that corresponds to the DefaultCharSetName.

299 > 6. Add ISQL style performance statistics collection to IStatement
300  
301 < 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
302 <   path is given and database attach fails due to access permission issues on the
314 <   temp directory or security database, then the attach is retried with "localhost:"
315 <   prefixing the databasename. This should avoid problems when the database has to
316 <   be accessed by a local (e.g. classic) server and libfbembed is used.
301 > 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
302 >   CREATE DATABASE statement.
303  
304 < 2. Windows: revised search order for Firebird DLL:
305 <     i.   The Firebird Embedded Server in the application Directory.
320 <     ii.  If the FIREBIRD environment variable is set then the directory this
321 <          points to is searched for the FB Client DLL and then then underlying
322 <          "bin" directory.
323 <     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
324 <          is used to locate the Firebird installation directory and the underlying
325 <          "bin" directory is searched for the FB Client DLL.
326 <     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
327 <          are searched for the FB Client DLL.
328 <     v.   The PATH Environment variable is used to search for the FB Client DLL.
329 <     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
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 < 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
308 <   See doc/readme.scriptengine and example applications.
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 < 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
311 <   simplify the use of the embedded firebird server on both Linux and Windows platforms.
312 <   See dpc/readme.localdatabase and example applications.
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 < 5. IBDynamicGrid: Reordering on column header click should now also work for
339 <   dynamic columns.
314 > 11. API Version information added as constants to IB.pas
315  
316 < 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
342 <   between incrementing/decrementing the lock count and signalling the event.

321  
322 < 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
322 > 1. Initial Release
323  
350 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
351
352 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
353
354 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
355   i.e. when it is a calculated field
356
357 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
358   This problem was due to a race condition between recalculating row heights and
359   determining which row was selected by the mouse click. The row height calculation
360   is now deferred by an extra trip round the message loop allowing the row to
361   be always calculated on the current grid layout rather than risking it being
362   calculated on the grid layout after the expanded row has been shrunk.
363
364 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
365   Windows.
366
367 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
368   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
369   to be determined at runtime. See doc/readme.charactersets.html.
370
371 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
372   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
373
374 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
375   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
376   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
377
378   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
379   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
380   implies no truncation.
381
382 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
383
384 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
385   (avoids "Not in Edit Mode" error).
386
387 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
388
389 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
390    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
391
392 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
393
394 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
395
396 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
397
398 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
399
400 IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
401
402 1.   OnCloseUp Event Handler added to TDBLookupProperties
403
404 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
405     problem with row size when exception is called.
406
407 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
408
409 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
410     in a TCustomComboBox and ignores return key if in a TCustomMemo
411
412 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
413     keyed in i.e. when autocomplete not performed
414
415 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
416     console mode applications with all LCL required functions (builtin dialogs and
417     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
418     not included in your project, IBX should compile and link with a console mode program.
419     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
420     console mode application or the IDE will automatically assume that your
421     application is GUI based. Instead, you should include the ibexpressconsolemode package.
422
423     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
424     to use the built in dialogs and cursor management. IBDialogs is
425     included by default if "ibexpress" is in your project source's "uses" clause.
426     This should be the case for all projects created through the IDE. This is why
427     you do not want to add the ibexpress package to console mode applications. The
428     ibexpressconsolemode package has been created to allow console mode programs
429     to avoid adding LCL dependencies when using IBX, while still having the
430     unit search paths set up correctly.
431
432     Existing users should check to ensure that the "ibexpress" unit is included in
433     each project's source file (*.lpr).
434
435     You may find that in order for the IDE to recognise that ibexpressconsolemode
436     exists, you have to first open the package in the IDE and then close it. This
437     adds it to the most recently accessed packages list. To make it permanently
438     available, add the package name to lazarus' staticpackages.inc file.
439
440         Thanks to Julio Jiménez for suggesting support of console mode.
441
442 7.   SQL Parser can now accept quoted strings that include new lines
443
444 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
445     of text on start of edit. This is particularly useful when tabbing to a
446     column and then inserting text.
447
448 9.   New Examples provided for IB Services and ISQLMonitor.
449
450 10. Fix error when writing to blob streams that recorded only the last buffer
451    write in the blob stream. In most cases, this did not cause a problem as the
452    IB Blob Stream is written in a single write. However, with the TDBImage, write
453    of a graphic type prefix was lost which caused a problem when the image could
454        not be automatically recognised.
455
456 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
457    already open" errors due to random numbers used for the cursor name being identical.
458
459 12. IBTable: corrected error that could result in an "Index out of bounds" error
460    when opening the table and the Primary Key is the last or only column in the
461    table. Thanks to Rick Hoover for the fix.
462
463 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
464    of "UTF-8", and update list of available database character sets. Existing
465    users should check the current lc_ctype setting in their applications.
466
467 IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
468
469 1.  Firebird Services: avoid List Index error when opening a service with an
470    empty Params property.
471
472 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
473    Link now set up in Loaded method - avoids occasional failure to apply
474    SQL markup on initial open.
475
476 3.  "Employees" example performance improvements when scrolling.
477
478 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
479    TFrame. Force recaching of selected frame to avoid GTK race (results in a
480    random image cached).
481
482 5.  DBControlGrid: Should now react to changes in panel height at run time.
483
484 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
485    even when further rows exist.
486
487 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
488    always be derived from panel height and setting this property can cause confusion.
489    Note for existing projects: to avoid a missing property error at run time,
490    each form using the DBControlGrid must be opened, updated and saved in the IDE
491    in order to remove the property value from the lfm.
492
493
494 IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
495
496 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
497    call Prepare before setting parameter values.
498
499 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
500
501 3.  Code tidyup and more robust handling of dsql information result vector.
502
503 4.  Support for centralised handling of transaction status changes. TIBTransaction
504    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
505    and "AfterExecQuery". The first three are called after the same event is called
506    for an IBCustomDataSet descendent using the Transaction. The fourth is called
507    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
508    enable monitoring of transaction status changes for a given transaction to be
509    handled in a single place. For example, when a change to the dataset occurs
510    an indicator can be set that shows the user that in order to save changes,
511    the transaction should be committed.  Rather than doing this per dataset, this
512    can now be done per transaction.
513
514 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
515    the dataset is scrolled. However, any changes to the current row are, by default,
516    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
517    have a new property "DataSetCloseAction" that adds automatic posting of changes
518    on dataset close. If this property is set to dcDiscardChanges (default) then the
519    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
520    then IBX will attempt to post any unsaved changes before the dataset is closed
521    (and after the BeforeClose event handler is called). The exception is when the
522    dataset is being closed as a result of a transaction rollback. In this case,
523    no action is taken and any unsaved  changes are discarded. This avoids both
524    unnecessary overhead and the risk that a validation error may occur in the Post
525    raising an exception and thereby preventing a rollback.
526
527 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
528    In earlier versions, the Display Width was set to the maximum byte width rather than the character
529    width. Display Widths are now corrected by dividing by the max byte width per character.
530    For UTF8 character sets, the byte width is four and hence the Display Width will be
531    the byte width divided by 4. The byte width of each character set is determined
532    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
533    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
534
535 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
536
537 8.  IBLookupComboEditBox: List should now always be restored to full list when the
538    control loses focus. Default Key press default interval reduced to 200ms.
539
540 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
541    when dataset rows are less than visible rows.
542
543 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
544    does not exist or DataSet is empty. More responsive on dataset open. New event
545    OnRestorePosition. Column sort disabled if no header row.
546
547 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
548    while dataset state is dsInsert. Avoids posting errors.
549
550 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
551    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
552
553 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
554
555 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
556    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
557    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
558    always "posts" the current record regardless or whether or not it may be more appropriate
559    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
560    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
561    as the first action of the "Post" method and allows the handler to convert the Post
562    into a Cancel if that is the appropriate action on moving to a different row. This is
563    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
564    raised here, but it may still be more appropriate to validate a post and signal
565    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
566
567 15. On Unix derived systems, the Firebird library name can now be given as a colon
568    separated list. Each library name on the list is tried in turn, in left to right
569    order with the first found being used as the firebird library. By default, on Linux,
570    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
571    overidden by the FBLIB environment variable or the OnGetLibraryName function.
572
573    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
574    then it will still attempt to access the database via the Firebird Server and will
575    require a username and password. If only the pathname is given, then the username
576    and password should be omitted and the unix file permissions are used to grant
577    access.
578
579 IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000

581 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
582    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
583    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
584    corresponds to a row of the linked DataSource. Any data aware control on the
585    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
586
587 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
588   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
589   takes place during database access. This may be useful when there are performance issues with
590   the change of cursor. Setting the property to false suppresses the change of cursor.
591
592 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
593   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
594   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
595   making all changes permanent immediately rather than when the transaction is explicitly
596   committed.
597
598 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
599   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

605 IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
606
607 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
608   This is typically used during an "OnBeforeOpen" event handler to manipulate the
609   "Where" and "Having" clauses to implement user specified filters of arbitrary
610   complexity.
611
612 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
613   three new data aware controls dependent on IBX and which make use of the SQL Parser.
614   These are:
615
616   - TIBLookupComboEditBox
617   - TIBDynamicGrid
618   - TIBTreeview
619
620   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
621   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
622   to revise the available list and restrict it to items that are prefixed by the
623   typed text (either case sensitive or case insensitive). Autoinsert allows a
624   newly typed entry to be added to the list dataset and included in the available
625   list items.
626
627   TIBDynamicGrid is a TDBGrid descendent that provides for:
628   - automatic resizing of selected columns to fill the available row length
629   - automatic positioning and sizing of a "totals" control, typically at the
630     column footer, on a per column basis.
631   - DataSet resorting on header row click, sorting the dataset by the selected column.
632     A second click on the same header cell reversed the sort order.
633   - Support for a "Panel Editor". That is on clicking the indicator column, the row
634     is automatically expanded and a panel superimposed on it. The panel can have any
635     number of child controls, typically data aware controls with the same datasource
636     as the grid allowing for editing of additional fields and more complex editors.
637   - Reselection of the same row following resorting.
638   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
639     Its properties are specified on a per column basis and allows for one or more
640     columns to have their values selected from a list provided by a dataset.
641     Autocomplete and autoinsert are also available. The existing picklist editor
642     is unaffected by the extension.
643
644   TIBTreeView is a data aware TCustomTreeView.
645
646 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
647   zero scale will no longer return an error. An Int64 will be returned instead.
648
649 4. TIBTransaction now has events for Before and After Transaction End and a new function
650   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
651
652 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
653   repeated multiple times.
654
655 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
656   check used to get in the way of using Stored Procedures, and "Update or Insert"
657   statements.
658
659 7. Insert, Modify and Delete property Editors now support Query Generation from
660   Stored Procedures.
661
662 8. Three new examples illustrate the use of the new IB Controls
663
664
665 IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
666
667 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
668   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
669   Gabor Boros for reporting this problem and for testing the improvements).
670
671 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
672   See readme.field+param.names in the doc folder.
673
674 3. IBX SQL Editors will now automatically add double quotes around column names when the database
675   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
676
677 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
678
679 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
680   actions.
681
682 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
683   thanks to Yuriy Kopnin for pointing this out).
684
685 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
686
687 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
688   for both fields and parameter setting.
689
690 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
691   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
692
693 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
694    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
695
696 11. TIBTable now has a property editor for "MasterFields"
697
698 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
699    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
700
701 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
702    of settings is unrecognised. Selecting this radio button has no effect on the settings.
703

705 IBX Change Log  version                 (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
706
707 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
708
709 IBX Change Log  version          (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
710
711 1. In a TIBCustomDataset descendent, a generator now only sets the value when
712   it is null. This allows for alternative user defined setting of the generator
713
714   Many thanks to Julio Jiménez for this fix
715
716 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
717   and suggests that the user may have forgotten to install it.
718
719 IBX Change Log  version         (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
720
721 1. Conditional compilation used to limit registration of TIntegerField to
722   Lazarus versions less than 1.1
723
724 2. When a database connection is created, character set is now by default set
725   to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
726   1250 to 1254.
727
728
729 IBX Change Log  version     (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
730
731 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
732
733
734 IBX Change Log  version    (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
735
736 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
737   Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
738
739 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
740   package is changed to do this (which it should do).
741
742 IBX Change Log  version (1.0-0)  Sat, 28 Apr 2012 16:43:00 +0100
743
744 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
745
746 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
747
748 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
749
750 4. Property editors should now correctly resize.
751
752 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
753   (restored original functionality)
754
755 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
756   library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
