1 > FBINTF Change Log  version          (1.1-6 Build 12214) Fri, 17 Jul 2020 23:10:11 +0100
2  
3 < 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
4 <   and is used to override the default settings in the client side "firebird.conf" This
5 <   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
6 <   Each line of the string list should be a setting in the same format as "firebird.conf".
7 <   For example "WireCompression = true" in order to request wire compression on the client side.
3 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
4 >   with a Firebrid 3 client library.
5  
6 <   Note: explicit settings in the client side "firebird.conf" appear to take precedence
7 <   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
8 <   also require a compatible setting in the server side "firebird.conf". For example
9 <   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
10 <   compression to be used.
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 <   Whether or not WireCompression or WireCrypt are in use can be checked using the information
16 <   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
17 <   ibx/examples/dbinfo for examples of how to display this information.
12 > 3.  IUtil.FormatStatus now used to format error messages when using new API
13  
14 < 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
20 <   is a "convenience" property. If set the "WireCompression=true" is added to the
21 <   ConfigOverrides. If unchecked then this setting is removed.
14 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
15  
16 < 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
17 <   not "INT64".
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 < 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
24 <   These are:
25 <    property TimestampFormat: string;
29 <    property DateFormat: string;
30 <    property TimeFormat: string;
23 > 6.  New IFirebirdAPI Calls:
24 >      function GetClientMajor: integer;
25 >      function GetClientMinor: integer;
26  
32   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
33   DATETIME and TIME. The format strings use the standard FPC date/time format
34   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
27  
28 <   If any of the above properties are set to an empty string, then the locale default
37 <   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
38 <   locale default is extended by appending '.zzz' to include milliseconds.
28 > FBINTF Change Log  version          (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +0100
29  
30 <   TIBCSVDataOut by default sets these properties to the empty string, while the other
31 <   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
30 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
31 >   case sensitive
32  
33 < 5. New published property for TIBCSVDataOut:
44 <     property QuoteStrings: boolean (default true)
33 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
34  
35 <   If false then strings are unquoted, otherwise, the QuoteChar property value is
36 <   used to delimit each and every string in the output.
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 < 6. New published properties for TIBCSVDataOut:
50 <    property FieldSeparator: string;
51 <    property HeaderSeparator: string;
43 > 4. FBMessages: removal of unused messages
44  
45 <   Respectively, these provide the separator character(s) used to separate fields
54 <   in data and header rows. Both default to ','.
45 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
46  
47 < 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
57 <    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
58 <    property OnFormatTextString;
47 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
48  
49 <   This event handler can be used to process text strings before they are included
61 <   in the output e.g. to replace unprintable characters with alternative strings.
62 <   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
49 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
50  
51 < 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
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 < 9. TIBQuery now uses IBX SQL Parser instead of TParams SQL parser in order to ensure
55 <   consistency with SQL queries.
54 > 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
55 >   This returns the isc_version connection information as one or more lines.
56 >   This is the same information as returned by isql with the -z option.
57  
58 < 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
59 <    When true, SQL statement parameter names are parsed case sensitive. Note for
60 <    TIBDataSet only applies to Select query.
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 < IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
62 > 4. IColumnMetaData: new method.
63  
64 < 1. Remove need to check for IsMultiThread by providing access to GUI timers via
65 <   IBGUIInterface. Note: master/detail delay timer does not apply to console
66 <   mode apps.
64 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
65 >                        dfDateTime,   {SQL DATETIME}
66 >                        dfTime);
67  
68 < 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
80 <   statement. This avoids problems if "Execute Block" is used as the Query.
68 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
69  
70 < 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
71 <   internal SQL tokeniser routines.
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 < 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
74 <   as a select statement, with or without CTEs.
73 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
74 >     CaseSensitiveParams: boolean = false
75  
76 < 5. IBSQLParser: parser now recognises the "ROWS" clause.
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 < 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
81 <   internal SQL tokeniser routines.
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  
93 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
94    being raised for valid set statements processed by a data formatter.
85  
96 8. New published property for TIBDatabase and TIBXServicesConnection. This is
97   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
98   the path of the Firebird Library used by the database/services connection.
86  
87 < 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
101 <   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
102 <   services connection.
87 > FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
88  
89 < 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
105 <   or param name is not a valid SQL identifier.
89 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
90  
91 < 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
92 <    view of whether the text box should be editable when no DataSource is specified.
109 <    TIBLookupComboEditBox has been updated to workaround this problem. As long as
110 <    ReadOnly is false, the text box is editable when no DataSource is specified.
91 > 2. Restrict IsMultiThread check to Unix only for compatibility with
92 >   https://bugs.freepascal.org/view.php?id=30535
93  
94 < 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
95 <    the FBLIB environment variable. If you do not want to permit this then you
96 <    must modify the Register procedure in the design/IBDBReg.pas unit to remove
115 <    this setting.
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 < IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
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 < 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
120 <   Utf8EscapeControlChars
101 > 5. New function added to IB.pas
102  
103 < IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
103 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
104  
105 < IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
106 < all previous copies of the IBX source code tree before installing this release.
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 < The IBX packages used by most users have not changed, with one exception. The
128 < IBServices unit has been moved to the package iblegacyServices.lpk. To continue
129 < to use the IBServices unit in your applications, please add the iblegacyServices
130 < to the list of dependencies. To do this, open the Project Inspector and select
131 < Add->New Requirement and select "ibLegacyServices" from the list of available
132 < packages.
110 > FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
111  
112 < 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
113 <   the IBServices unit providing what is intended to be a clearer and easier to
136 <   use set of IB Services components. See Chapter 10 of the IBX User Guide for
137 <   more information and the guide to "Firebird Service Management Using IBX".
138 <   As indicated above, the legacy services components are still available and
139 <   provided in a separate package. There is no need to update working applications
140 <   using the older versions except for an additional package dependency.
112 > 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
113 >   program compiled with -CR command line switch.
114  
115 < 2. The IBX packages and source code tree have been re-organised in an attempt to
116 <   finally get rid of the "duplicate ppu" warnings. This re-organisation should
117 <   not affect existing users. Section 2.3 of the IBX User Guide describes the
145 <   new set of IBX packages.
115 > 2. IServiceManager additions (informational):
116 >    function getProtocol: TProtocol;
117 >    function getPortNo: AnsiString;
118  
119 < 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
120 <   updated to use the new Services API components.
119 > 3. IServiceManager improved error handling. Interfaces changed:
120 >    function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
121 >    function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
122 >    function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
123  
124 < 4. The iblocal package has been updated to use the new Services API components.
124 > 4. IAttachment addition (informational)
125 >    function GetSecurityDatabase: AnsiString;
126  
127 < 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
128 <   TIBXSecurityService. It had been wrongly classified in the previous version
129 <   as a per database configuration item. It is global to a server and hence
155 <   correctly positioned as part of the Security Package. In the DBAdmin example,
156 <   the setting has moved to the mappings page.
127 > 5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
128 >   thus now returns accumulated stats for a select statement from opening a cursor
129 >   up to the last fetch.
130  
131 < 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
132 <   are ignored.
131 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
132 >   the problem.
133  
134 < 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
135 <   closed before the database is dropped. Before and After Disconnect event handlers
163 <   are also fired.
134 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
135 >   replaces deprecated "comp" type.
136  
137 < 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
166 <   is started and not just the first time.
137 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
138  
139 < 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
169 <   depenendency with comp type.
139 > 11. URL Connection Strings: inet4 and inet6 now recognised.
140  
141 < 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
141 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
142  
143 < 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
174 <    then this is recognised and not ignored.
143 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
144  
176 12. TIBDataSet, TIBQuery, TIBTable: additions:
177    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
178    function GetPerfStatistics(var stats: TPerfCounters): boolean;
179    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
145  
146 <    GetRowsAffected returns the affected row counts from the last insert/update/delete
182 <    if EnableStatistics = true then GetPerfStatistics returns the current stats
183 <    counters for the select query. Note: stats accumulate after each fetch from
184 <    the database. To get total query cost after open, call the "Last" method
185 <    and then GetPerfStatistics.
146 > FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
147  
148 <    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
148 > 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
149  
150 < 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
151 <    in parenthesises.
150 > 2. IAttachment: add two new methods
151 >     function HasDefaultCharSet: boolean;
152 >     function GetDefaultCharSetID: integer;
153  
154 < 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
155 <    SQL identifiers are always delimited by double quotes. If false, then they are
156 <    only delimited if the identifier is a reserved word, contains lower case or special
157 <    characters. Set this property to true to retain previous behaviour.
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 < 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
198 <    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
159 > 3. Avoid exception when a text blob is a stored procedure parameter.
160  
161 < 16. TIBDataSet, TIBQuery, TIBTable: addition:
201 <       property MasterDetailDelay: integer {defaults to zero}
161 > 4. Update test suite to include a test for a stored proc returning a text blob.
162  
163 <    When non-zero and the dataset is a detail table referencing a master table
164 <    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
165 <    then a synchronisation delay is added (in milliseconds) between the master
166 <    row changing and the detail dataset being re-opened. If the master dataset
167 <    is scrolled before the delay expires then the delay is reset. This can be used
208 <    to avoid performance overheads when scrolling through a large master dataset.
163 > 5. IAttachment: add
164 >      function GetRemoteProtocol: AnsiString;
165 >      function GetODSMajorVersion: integer;
166 >      function GetODSMinorVersion: integer;
167 >      function GetAuthenticationMethod: AnsiString;
168  
169 <    Note: uses fptimer and hence requires a thread manager. Under Linux the
170 <    chreads unit must be included in your project. TTimer is not used in order
212 <    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
169 >   These results are cached when the connection is opened and hence do not
170 >   require a database lookup.
171  
172 < 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
173 <    with Extract Option eoDatabase.
172 > 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
173 >   connect string used to create/connect to the database.
174  
175 < 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
176 <    When a deLayoutChanged event is reported on the ListSource dataset, the
177 <    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
178 <    relationship with the control's datasource (master).
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 < 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
181 > 8. Update Test 1 to test 5, 6 and 7 above.
182  
183 < 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
225 <    stubs. Pedantic fix really, as procedures output in dependency order anyway.
183 > 9. IBUtils code tidy up.
184  
185 < 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
186 <    DDL (Firebird 3 and later only).
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 < 22. TIBLookupComboBox Autocomplete Fixes:
231 <    i. Only appended text is now selected after autocomplete.
232 <    ii. Uppercase keys no longer ignored for autocomplete.
233 <    iii. Retain Prefix case is now honoured correctly.
234 <    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
235 <        before autocomplete performed. i.e. behaviour now the same as when
236 <        no DataSource assigned.
190 > 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
191  
192 < 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
193 <    between SQL statements.
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 < 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
198 <    ObjectNames are converted to upper case before matching against metadata object
243 <    names, unless the objectname is delimited by double quotes, in which case, the
244 <    double quotes are removed and the remaining string is used (unmodified) to match
245 <    against the metadata object name.
197 > 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
198 >    test suite updated.
199  
200 <    If true then the ObjectName is used as is without modification and matched
201 <    against the metadata object name. No attempt is made to remove double quotes.
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 < 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
204 <    with eoTrigger, these extract types can be used to select only Database Triggers,
205 <    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
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 < 26. TIBXScript: If an exception occurs during the processing of a statement, the
255 <    statement separate character is now reset to the default (';').
207 > FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
208  
209 < 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
209 > 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
210 >   Scale is no longer ignored.
211  
212 < 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
213 <    a commit or reconnect statement and instead activated only when next SQL statement
214 <    is executed.
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 < 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
217 > 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
218 >   UTF8 and not UNICODE_FSS.
219  
220 < 30. TIBXScript: case insensitive regex now used when matching statements instead of
221 <    converting statement to upper case.
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 < 31. TIBExtract: metadata comments now supported. New published property
226 <    IncludeMetaDataComments (default true). If true then metadata comments included
227 <    in extracted DDL. New Extract Object member eoComments. This may be used with
228 <    ExtractObject method to list all metadata comments.
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 < 32. TIBExtract: ListObjectNames method added.
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 < 33. Updated Database component editor to support additional connection string
234 <    types.
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 < IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
236 > 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
237  
238 < NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
239 < AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
240 < RELEASE.
238 > 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
239 >   library or finding it by disk location, the PATH environment variable is now also set to
240 >   include the FIREBIRD directory. This is to ensure that the correct dlls in the
241 >   firebird client library dependencies are loaded.
242  
243 < NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
243 > 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
244  
245 < 1. IBExtract: Identity columns - add additional check for null column for generator name.
245 > 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
246  
247 < 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
289 <   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
290 <   information). However, this is also a very useful mechanism for returning updated computed by
291 <   column values. Values returned as a result of executing an Insert or Update statement
292 <   replace existing values in the current row for each corresponding column.
247 > 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
248  
249 <   Previously, if a dataset's select query included read only (computed by) fields then
250 <   an automatic row refresh was performed after an insert or update query had been processed,
251 <   irrespective of the setting of the "ForcedUpdates" property. This has changed such
252 <   that an automatic refresh is no longer performed if an insert or update query contains
298 <   a returning clause that updates one or more fields on the current row. A full row
299 <   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
300 <   field values and the select query contains read only fields. Use of Insert/update
301 <   returning should be significantly more efficient than executing a refresh query.
249 > 13. FB30Statement: A check has been added to ensure that all SQL Parameters
250 >    have been given a value (including NULL). Previously, failing to set the
251 >    value of an SQL Parameter could give rise to unpredictable results or
252 >    an SQLDA error.
253  
254 <   This behaviour change is intended to be backwards compatible and there should be no need to change
304 <   existing programs, other than to improve performance by using the new capability.
254 > 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
255  
256 < 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
257 <   they are called when the dataset row is being deleted, there is no value in
308 <   updating the current record from the query result. Instead, a new event handler
309 <   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
310 <   an OnDeleteReturning event handler is provided then it is called with the IResults returned
311 <   by the query. The event handler can then interrogate the query results and
312 <   perform whatever action is necessary. For example to confirm, to the user,
313 <   the deletion of a row with the returned values.
256 > 15. FBAttachment: Avoid string reference count error when processing an Ansistring
257 >    parameter in an array of const passed to IAttachment.OpenCursor, etc.
258  
259 < 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
260 <   any Computed By or Identity Columns. The IBTables example has been updated to
317 <   illustrate the computation of the employee Full Name on update.
259 > 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
260 >    of const passed to IAttachment.OpenCursor, etc.
261  
319 5. TIBTable: The GeneratorField property is now published.
262  
263 < 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
322 <   When InsertSQL is generated, the Identity columns are not included in the list of values to
323 <   be inserted. A RETURNING clause is added to the insert statement to return the value of
324 <   each Identity column after the insert is executed.
263 > FBINTF Change Log  version             (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
264  
265 < 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
327 <   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
328 <   Insert..Returning clause.
265 > 1. Change syntax to Mode Delphi
266  
267 < 8. TIBGenerator: small performance improvement by not preparing query each time
268 <   a new value is generated.
267 > 2. Change all uses of string type to explicit AnsiString in order to ensure
268 >   compatibility between Delphi and FPC.
269  
270 < 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
270 > 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
271 >   defined for each interface.
272  
273 < 10. Property editors will now sync table name to a System Table when "Include System
336 <    Tables" is selected and the query is for a System Table.
273 > 4. Generics syntax variations for Delphi added
274  
275 < 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
276 <    values are no longer converted to milliseconds from TDateTime and then back again
340 <    to TDateTime (the conversion to milliseconds is the default TDataset approach).
275 > 5. PChar replaced with PByte expect where an actual string is being referenced,
276 >   where PAnsiChar is used instead.
277  
278 < 12. Property Editors handling of Stored Procedures.
343 <    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
344 <      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
345 <      query).
346 <    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
278 > 6. Review of type definitions in IBExternals to ensure Delphi compatibility
279  
280 < 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
349 <    can be used to select a package. If non-empty, the stored procedure name is
350 <    expected to be a stored procedure defined in the specified package and the
351 <    generated SQL will be as required for a stored procedure located in a package.
280 > 7. Testsuite updated for Delphi
281  
282 < 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
354 <    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
355 <    which a stored procedure can be selected. With no package name selected, non-package
356 <    stored procedures are listed.
282 > FBINTF Change Log  version            (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
283  
284 < 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
285 <    for password on reconnect.
284 > 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
285 >   large blobs and the FB3 API.
286  
287 < 16. TIBDatabase: use IAttachment for connection default character set id, code page
288 <    and character set name.
287 > 2. Update Event Handling algorithm to avoid looping due to recreation of the
288 >   event block.
289  
290 < 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
365 <    DB info lookups"
290 > 3. Avoid invalid XSQLDA error when the only parameter is updated to null
291  
292 < 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
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 < 19. Add a property Editor for TIBUpdate.RefreshSQL.
297 > 5. IBUtils: List of reserved words brought up-to-date
298  
299 < 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
372 <    parameters. This stops an exception being raised when the field cannot be
373 <    located in the record buffer.
299 > 6. Add ISQL style performance statistics collection to IStatement
300  
301 < 21. Property Editors now automatically include System Tables when opened and when the query table
302 <    is a System Table.
301 > 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
302 >   CREATE DATABASE statement.
303  
304 < 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
305 <    This avoids errors due to a stale SQRB or SRB being used for the next query.
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 < 23. IBServices: Service attach parameters now include "expected_db". This is used to
308 <    add the SPB item isc_spb_expected_db. This names a database using
383 <    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
384 <    database. examples/services re-written to illustrate use of "expected_db".
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 < 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
311 <    This avoids truncated backups when the server returns a timeout (busy) response.
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 < 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
314 > 11. API Version information added as constants to IB.pas
315  
316 < 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
392 <    databasenames. These are respectively expanded to the local system's temp directory
393 <    (including trailing delimiter) or to a prescribed data directory (including
394 <    trailing delimiter). Under Unix systems the data directory is a hidden directory
395 <    in the user's home directory. The hidden directory name is either the string returned
396 <    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
397 <    Under Windows, the directory is the same as the Data Directory as decribed
398 <    above but instead prefixed by the User's application data path. These may be
399 <    used to improve application portability for Personal Databases.
316 > 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
317  
318 < 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
402 <    this has not worked for a long time and is not useful either. FieldDefs should be
403 <    managed using the Fields Editor as with any other dataset. To access the fields
404 <    editor for a TIBTable component, double click on the component. The fields editor
405 <    is then displayed.
318 > 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
319  
320 < 28. TIBDatabaseInfo: new properties/function
408 <     * DateDBCreated (returns date/time database created)
409 <     * TransactionCount (returns no. of active transactions)
410 <     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
411 <     * PagesFree (Firebird 3 or later)
412 <     * PagesUsed (Firebird 3 or later)
413 <     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
414 <     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
320 > FBINTF Change Log  version                                      (1.0-0) Tue, 06 Dec 2016 10:33:47 +0000
321  
322 < 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
322 > 1. Initial Release
323  
418 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
419
420 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
421    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
422
423 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
424    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
425    firing during backup and restore.
426
427 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
428    for verbose output using the new property "StatisticsRequested".
429    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
430
431 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
432
433 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
434    palette. This uses the online validation feature added in Firebird 2.5. The
435    services's properties enable inclusion/exclusion of tables and indexes using
436    regular expressions. See.
437    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
438
439 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
440    option on a database.
441
442 37. TIBCustomService: Assign method implemented to allow copying of service login
443    context between service API components. "Detach" method now only detaches
444    service when last reference to the service interface detaches. Tidy up of
445    code for SetActive and Attach methods including password hiding.
446
447 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
448    and used to determine the auth method and protocol used for the connection.
449
450 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
451    a Create Database Statement generated by IBX.
452
453 40. All IBServices now have an additional published property "PortNo". This may
454    be set to a non-standard port number when necessary. If zero then the default
455    port number is used.
456
457 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
458    and not just the mouse.
459
460 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
461
462 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
463    image index and selected image index for each node to be set from a database field.
464
465 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
466    then database schema includes grants to all users. If not present then the
467    only user grants included are those to User PUBLIC.
468
469 45. TIBTreeView: performance improvement. When expanding include both expanded node
470    and child nodes in dataset.
471
472
473 IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
474
475 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
476   changes.
477
478 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
479   Bug could result in truncated multi-byte character set values.
480
481 3. Changes consequential on moving fbintf character set utility functions from
482   IFirebirdAPI to IAttachment.
483
484 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
485
486 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
487   results in autocomplete ignoring prefix text.
488
489 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
490   entering a new name into the text box.
491
492 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
493   Firebird rather than recomputing it.
494
495 8. Property Editor positioning tidy up: All IBX Property editors should now be
496   screen centre. Previously some were "poDesigned" which may be inappropriate
497   for multi monitor desktops.
498
499 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
500
501 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
502    a transaction and always reset the object.
503
504 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
505
506 13. TIBXScript: Allow for override of database filename in Create Database statements.
507
508 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
509    to a gbak format archive.
510
511 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
512
513 16. IBLocaldb: Drop database if error creating an empty database.
514
515 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
516    unless selected node not in current dataset.
517
518 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
519    to TIBCustomService, and IBlocalDB code tidy up.
520
521 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
522    behaviour due to uninitialised variable.
523
524 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
525    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
526
527 21. IBSQL: When Database changed ensure that all resources are freed.
528
529 22. IBCustomDataset: When database changed ensure that queries an unprepared.
530
531 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
532    * Line Wrap on SQL Token boundaries (on user command)
533    * auto-complete table names in drop down list of table names
534    * Double click on tablename or field name adds to SQL text
535
536 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
537
538 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
539    TVariantArray. Seems to avoid memory corruption in Windows (probably a
540    workaround for a problem in fpc 3.0.4 win64).
541
542 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
543
544 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
545
546 IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
547
548 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
549   include remote system name.
550
551 2. TIBExtract: No longer include comment header and COMMIT statement for empty
552   tables when data included in output.
553
554 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
555   and timing information to be written to stdout. This may be used to locate
556   performance bottlenecks.
557
558 4. SQLParser: only call "OnChanging" event handler when value is different.
559
560 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
561
562 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
563   that BindFields is called when the query is next activated. Avoids FieldName
564   not found error.
565
566 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
567   purpose and allows the programmer to define any action they want for Update, Insert
568   or Delete. This may be complex SQL (similar to a Trigger), application specific
569   filtering of updates, or use of statements such as Grant or Revoke instead of
570   normal DML. See User Manual for more information.
571
572 IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
573
574 1. TIBEvents: Fix uninitialised variable that could result in lost events.
575
576 2. TIBExtract: Added support for FB3 "USAGE" privilege.
577
578 3. TIBExtract: data formatted as Charset set "octets" is now output using
579   hexadecimal notation.
580
581 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
582   using a simple XML format.
583
584 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
585   grants to these objects.
586
587 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
588   dependency problems restoring complex databases.
589
590 7. TIBXScript: This component has been restructured to allow for the processing of
591   embedded XML in INSERT statements and to support interactive sources in addition
592   to non-interactive data sources such as files.
593
594 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
595
596 9. TIBXScript: ISQL compatiable Set statements are now supported:
597   SET SQL DIALECT
598   SET TERM
599   SET AUTODDL
600   SET BAIL
601   SET ECHO
602   SET COUNT
603   SET STATS
604   SET NAMES <character set>
605
606 10. IBVersion unit added to hold current IBX Version Number information.
607
608 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
609    and domain definitions.
610
611 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
612    fully supported.
613
614 13. TIBExtract: when a database dump includes data, the generator values are now also set.
615
616 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
617
618 IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
619
620 See also doc/IBX4LazarusGuide.pdf for important information on
621 upgrading to IBX2.
622
623 1. Size property of TIBStringField is now the width in characters of the field
624   and not the byte length. This applies only to multi-byte character sets such
625   as UTF8. The original approach aligned with TStringField. However, the TStringField
626   code is not recognised as a bug and hence this change to align the behaviour.
627   The TStringField change is expected in fpc 3.2.0.
628
629 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
630   true (default) then Size property value saved in the lfm is ignored. Size is
631   always set from the dynamic information read from the database. It is unclear
632   why anyone would want to override this and set Size to false.
633
634 3. ibxscript: should now handle correctly a Case..End statement within a procedure
635   block.
636
637 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
638   exist when an attempt is made to connect to it (run time only) then an attempt
639   is made to create the database.
640
641 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
642   has been successfully created as a result of a call to CreateDatabase or when
643   creating a database after it was found not to exist.
644
645 6.  DBControlGrid: a race condition could result in the wrong row image being
646    written to the cache. This has been avoided by a trip round the message
647    loop before rendering the row image.
648
649 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
650    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
651    known to risk corrupt rendering of row images when the control is first
652    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
653    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
654
655 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
656    a TDateEdit control located on an editor panel.
657
658 9.  TIBExtract: brought up-to-date plus many bug fixes.
659
660 10. DBControlGrid: Removed memory leak when updating rows.
661
662 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
663
664 IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
665
666 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
667   when target codepage is CP_NONE. This is a workaround for
668   http://bugs.freepascal.org/view.php?id=30622.
669
670 2. DBLog option removed from TIBStatisticalService - not supported by server
671   since Firebird 1.5.
672
673 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
674   similar.
675
676 4. IBCodePage: updated mapping between codepages and character id.
677
678 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
679   Firebird. Character sets with a char width of two are not UTF16.
680
681 6. Strings received from the database are now always transliterated into UTF8
682   regardless of the database character set or connection character set. This
683   is for compatibility with the LCL.
684
685 IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
686
687 1. IBBlob: Defer reading of blob until read method called. This avoids having to
688   read in an entire blob just to get the size of the blob. General performance
689   improvement when opening datasets containing blobs.
690
691 2. Clearing a  Blob now sets the corresponding field's modified flag.
692
693 3. IBLookupCombo: When not performing auto-complete, original query sort order
694   is now used.
695
696 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
697   determined.
698
699 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
700
701 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
702   lazarus 1.6.0
703
704 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
705   compilation error.
706
707 IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
708
709 1. No character set specified for connection: when a text blob is retrieved, the
710  character set is determined by looking up the native character set using then
711  Firebird API. Otherwise a text mode blob is assumed to have the same character
712  set as the connection.
713
714 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
715   for Login Dialog returing a change to the database path.
716
717 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
718   to be changed from that given in the TIBDatabase/TIBServer component and for the
719   entered value to be saved on a project specific basis (design time only).
720
721 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
722   column fieldname. If they are the same then it is acts as a look up for the KeyValue
723   Otherwise, it sets the column text to the selected ListField Value.
724
725 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
726   column width.
727
728 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
729   and a case insensitive search is requested.
730
731 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
732   or column ListSource.
733
734 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
735   unprepare) when closing and the text has not changed.
736
737 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
738   Less likely to cause a cursor re-use error on Windows.
739
740 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
741   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
742
743 11. TIBTreeView: Guard against nil destination on record changed
744
745 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
746    string type with the code page set to reflect the returned field encoding after
747    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
748    earlier versions.
749
750 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
751    will now result in transliteration to the code page specified for the Firebird driver
752    if the assigned string has a different code page. FPC 3.0.0 onwards only.
753
754 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
755    is ignored and the lc_ctype value, when the database is opened, is set to align with
756    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
757    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
758    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
759    the GETACP is used to determine the Windows code page.
760
761 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
762    name used as the lc_ctype when the database was opened. Only valid while the
763    Database is connected.
764
765 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
766    id that corresponds to the DefaultCharSetName.
767
768 IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
769
770 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
771   path is given and database attach fails due to access permission issues on the
772   temp directory or security database, then the attach is retried with "localhost:"
773   prefixing the databasename. This should avoid problems when the database has to
774   be accessed by a local (e.g. classic) server and libfbembed is used.
775
776 2. Windows: revised search order for Firebird DLL:
777     i.   The Firebird Embedded Server in the application Directory.
778     ii.  If the FIREBIRD environment variable is set then the directory this
779          points to is searched for the FB Client DLL and then then underlying
780          "bin" directory.
781     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
782          is used to locate the Firebird installation directory and the underlying
783          "bin" directory is searched for the FB Client DLL.
784     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
785          are searched for the FB Client DLL.
786     v.   The PATH Environment variable is used to search for the FB Client DLL.
787     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
788
789 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
790   See doc/readme.scriptengine and example applications.
791
792 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
793   simplify the use of the embedded firebird server on both Linux and Windows platforms.
794   See dpc/readme.localdatabase and example applications.
795
796 5. IBDynamicGrid: Reordering on column header click should now also work for
797   dynamic columns.
798
799 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
800   between incrementing/decrementing the lock count and signalling the event.
801
802 IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
803
804 1.3.2 was never formally released and only made available as beta copies.
805
806 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
807
808 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
809
810 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
811
812 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
813   i.e. when it is a calculated field
814
815 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
816   This problem was due to a race condition between recalculating row heights and
817   determining which row was selected by the mouse click. The row height calculation
818   is now deferred by an extra trip round the message loop allowing the row to
819   be always calculated on the current grid layout rather than risking it being
820   calculated on the grid layout after the expanded row has been shrunk.
821
822 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
823   Windows.
824
825 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
826   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
827   to be determined at runtime. See doc/readme.charactersets.html.
828
829 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
830   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
831
832 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
833   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
834   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
835
836   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
837   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
838   implies no truncation.
839
840 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
841
842 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
843   (avoids "Not in Edit Mode" error).
844
845 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
846
847 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
848    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
849
850 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
851
852 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
853
854 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
855
856 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
857
858 IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
859
860 1.   OnCloseUp Event Handler added to TDBLookupProperties
861
862 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
863     problem with row size when exception is called.
864
865 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
866
867 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
868     in a TCustomComboBox and ignores return key if in a TCustomMemo
869
870 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
871     keyed in i.e. when autocomplete not performed
872
873 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
874     console mode applications with all LCL required functions (builtin dialogs and
875     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
876     not included in your project, IBX should compile and link with a console mode program.
877     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
878     console mode application or the IDE will automatically assume that your
879     application is GUI based. Instead, you should include the ibexpressconsolemode package.
880
881     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
882     to use the built in dialogs and cursor management. IBDialogs is
883     included by default if "ibexpress" is in your project source's "uses" clause.
884     This should be the case for all projects created through the IDE. This is why
885     you do not want to add the ibexpress package to console mode applications. The
886     ibexpressconsolemode package has been created to allow console mode programs
887     to avoid adding LCL dependencies when using IBX, while still having the
888     unit search paths set up correctly.
889
890     Existing users should check to ensure that the "ibexpress" unit is included in
891     each project's source file (*.lpr).
892
893     You may find that in order for the IDE to recognise that ibexpressconsolemode
894     exists, you have to first open the package in the IDE and then close it. This
895     adds it to the most recently accessed packages list. To make it permanently
896     available, add the package name to lazarus' staticpackages.inc file.
897
898         Thanks to Julio Jiménez for suggesting support of console mode.
899
900 7.   SQL Parser can now accept quoted strings that include new lines
901
902 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
903     of text on start of edit. This is particularly useful when tabbing to a
904     column and then inserting text.
905
906 9.   New Examples provided for IB Services and ISQLMonitor.
907
908 10. Fix error when writing to blob streams that recorded only the last buffer
909    write in the blob stream. In most cases, this did not cause a problem as the
910    IB Blob Stream is written in a single write. However, with the TDBImage, write
911    of a graphic type prefix was lost which caused a problem when the image could
912        not be automatically recognised.
913
914 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
915    already open" errors due to random numbers used for the cursor name being identical.
916
917 12. IBTable: corrected error that could result in an "Index out of bounds" error
918    when opening the table and the Primary Key is the last or only column in the
919    table. Thanks to Rick Hoover for the fix.
920
921 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
922    of "UTF-8", and update list of available database character sets. Existing
923    users should check the current lc_ctype setting in their applications.
924
925 IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
926
927 1.  Firebird Services: avoid List Index error when opening a service with an
928    empty Params property.
929
930 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
931    Link now set up in Loaded method - avoids occasional failure to apply
932    SQL markup on initial open.
933
934 3.  "Employees" example performance improvements when scrolling.
935
936 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
937    TFrame. Force recaching of selected frame to avoid GTK race (results in a
938    random image cached).
939
940 5.  DBControlGrid: Should now react to changes in panel height at run time.
941
942 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
943    even when further rows exist.
944
945 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
946    always be derived from panel height and setting this property can cause confusion.
947    Note for existing projects: to avoid a missing property error at run time,
948    each form using the DBControlGrid must be opened, updated and saved in the IDE
949    in order to remove the property value from the lfm.
950
951
952 IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
953
954 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
955    call Prepare before setting parameter values.
956
957 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
958
959 3.  Code tidyup and more robust handling of dsql information result vector.
960
961 4.  Support for centralised handling of transaction status changes. TIBTransaction
962    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
963    and "AfterExecQuery". The first three are called after the same event is called
964    for an IBCustomDataSet descendent using the Transaction. The fourth is called
965    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
966    enable monitoring of transaction status changes for a given transaction to be
967    handled in a single place. For example, when a change to the dataset occurs
968    an indicator can be set that shows the user that in order to save changes,
969    the transaction should be committed.  Rather than doing this per dataset, this
970    can now be done per transaction.
971
972 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
973    the dataset is scrolled. However, any changes to the current row are, by default,
974    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
975    have a new property "DataSetCloseAction" that adds automatic posting of changes
976    on dataset close. If this property is set to dcDiscardChanges (default) then the
977    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
978    then IBX will attempt to post any unsaved changes before the dataset is closed
979    (and after the BeforeClose event handler is called). The exception is when the
980    dataset is being closed as a result of a transaction rollback. In this case,
981    no action is taken and any unsaved  changes are discarded. This avoids both
982    unnecessary overhead and the risk that a validation error may occur in the Post
983    raising an exception and thereby preventing a rollback.
984
985 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
986    In earlier versions, the Display Width was set to the maximum byte width rather than the character
987    width. Display Widths are now corrected by dividing by the max byte width per character.
988    For UTF8 character sets, the byte width is four and hence the Display Width will be
989    the byte width divided by 4. The byte width of each character set is determined
990    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
991    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
992
993 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
994
995 8.  IBLookupComboEditBox: List should now always be restored to full list when the
996    control loses focus. Default Key press default interval reduced to 200ms.
997
998 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
999    when dataset rows are less than visible rows.
1000
1001 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1002    does not exist or DataSet is empty. More responsive on dataset open. New event
1003    OnRestorePosition. Column sort disabled if no header row.
1004
1005 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1006    while dataset state is dsInsert. Avoids posting errors.
1007
1008 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1009    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1010
1011 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1012
1013 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1014    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1015    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1016    always "posts" the current record regardless or whether or not it may be more appropriate
1017    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1018    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1019    as the first action of the "Post" method and allows the handler to convert the Post
1020    into a Cancel if that is the appropriate action on moving to a different row. This is
1021    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1022    raised here, but it may still be more appropriate to validate a post and signal
1023    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1024
1025 15. On Unix derived systems, the Firebird library name can now be given as a colon
1026    separated list. Each library name on the list is tried in turn, in left to right
1027    order with the first found being used as the firebird library. By default, on Linux,
1028    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1029    overidden by the FBLIB environment variable or the OnGetLibraryName function.
1030
1031    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1032    then it will still attempt to access the database via the Firebird Server and will
1033    require a username and password. If only the pathname is given, then the username
1034    and password should be omitted and the unix file permissions are used to grant
1035    access.

1037 IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1038
1039 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1040    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1041    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1042    corresponds to a row of the linked DataSource. Any data aware control on the
1043    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1044
1045 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1046   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1047   takes place during database access. This may be useful when there are performance issues with
1048   the change of cursor. Setting the property to false suppresses the change of cursor.
1049
1050 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1051   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1052   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1053   making all changes permanent immediately rather than when the transaction is explicitly
1054   committed.
1055
1056 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1057   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

1063 IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1064
1065 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1066   This is typically used during an "OnBeforeOpen" event handler to manipulate the
1067   "Where" and "Having" clauses to implement user specified filters of arbitrary
1068   complexity.
1069
1070 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1071   three new data aware controls dependent on IBX and which make use of the SQL Parser.
1072   These are:
1073
1074   - TIBLookupComboEditBox
1075   - TIBDynamicGrid
1076   - TIBTreeview
1077
1078   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1079   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1080   to revise the available list and restrict it to items that are prefixed by the
1081   typed text (either case sensitive or case insensitive). Autoinsert allows a
1082   newly typed entry to be added to the list dataset and included in the available
1083   list items.
1084
1085   TIBDynamicGrid is a TDBGrid descendent that provides for:
1086   - automatic resizing of selected columns to fill the available row length
1087   - automatic positioning and sizing of a "totals" control, typically at the
1088     column footer, on a per column basis.
1089   - DataSet resorting on header row click, sorting the dataset by the selected column.
1090     A second click on the same header cell reversed the sort order.
1091   - Support for a "Panel Editor". That is on clicking the indicator column, the row
1092     is automatically expanded and a panel superimposed on it. The panel can have any
1093     number of child controls, typically data aware controls with the same datasource
1094     as the grid allowing for editing of additional fields and more complex editors.
1095   - Reselection of the same row following resorting.
1096   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1097     Its properties are specified on a per column basis and allows for one or more
1098     columns to have their values selected from a list provided by a dataset.
1099     Autocomplete and autoinsert are also available. The existing picklist editor
1100     is unaffected by the extension.
1101
1102   TIBTreeView is a data aware TCustomTreeView.
1103
1104 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1105   zero scale will no longer return an error. An Int64 will be returned instead.
1106
1107 4. TIBTransaction now has events for Before and After Transaction End and a new function
1108   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1109
1110 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1111   repeated multiple times.
1112
1113 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1114   check used to get in the way of using Stored Procedures, and "Update or Insert"
1115   statements.
1116
1117 7. Insert, Modify and Delete property Editors now support Query Generation from
1118   Stored Procedures.
1119
1120 8. Three new examples illustrate the use of the new IB Controls
1121
1122
1123 IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1124
1125 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1126   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1127   Gabor Boros for reporting this problem and for testing the improvements).
1128
1129 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1130   See readme.field+param.names in the doc folder.
1131
1132 3. IBX SQL Editors will now automatically add double quotes around column names when the database
1133   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1134
1135 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1136
1137 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1138   actions.
1139
1140 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1141   thanks to Yuriy Kopnin for pointing this out).
1142
1143 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1144
1145 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1146   for both fields and parameter setting.
1147
1148 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1149   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1150
1151 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1152    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1153
1154 11. TIBTable now has a property editor for "MasterFields"
1155
1156 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1157    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1158
1159 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1160    of settings is unrecognised. Selecting this radio button has no effect on the settings.
1161

1163 IBX Change Log  version                 (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
1164
1165 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1166
1167 IBX Change Log  version          (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1168
1169 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1170   it is null. This allows for alternative user defined setting of the generator
1171
1172   Many thanks to Julio Jiménez for this fix
1173
1174 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1175   and suggests that the user may have forgotten to install it.
1176
1177 IBX Change Log  version         (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1178
1179 1. Conditional compilation used to limit registration of TIntegerField to
1180   Lazarus versions less than 1.1
1181
1182 2. When a database connection is created, character set is now by default set
1183   to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1184   1250 to 1254.
1185
1186
1187 IBX Change Log  version     (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
1188
1189 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1190
1191
1192 IBX Change Log  version    (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1193
1194 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1195   Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1196
1197 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1198   package is changed to do this (which it should do).
1199
1200 IBX Change Log  version (1.0-0)  Sat, 28 Apr 2012 16:43:00 +0100
1201
1202 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1203
1204 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1205
1206 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1207
1208 4. Property editors should now correctly resize.
1209
1210 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1211   (restored original functionality)
1212
1213 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1214   library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
