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

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 (';').

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.

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.

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)

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.

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.

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.

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.

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	–

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.

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.

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.

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.

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.

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.

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

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.
