2 +
3 + 1. Fixed repeated "type" keyword in IBBufferCursors. This may cause a compile error
4 +   with later versions of fpc - later than 3.2.2.
5 +
6 + 2. IBUpdateSQL. update internal queries if parent dataset database changed.
7 +
8 + 3. IBUpdateSQL: Do not prepare an empty internal query.
9 +
10 + 4. IBBufferedCursors: avoid range error when max field no. is > fields.count
11 +
12 + 5. IBBufferedCursors: avoid End of File error if refresh query returns and empty row count
13 +
14 + IBX Change Log  version (2.6-1 Build 13985) Mon, 17 Jul 2023 14:16:41 +0100
15 +
16 + 1. Maintenance update of 2.6.0. This version is still at beta.
17 +
18 + 2. Reverse out changes to DrawCellText signature in IBArrayGrid and IBDynamic Grid.
19 +   See https://gitlab.com/freepascal.org/lazarus/lazarus/-/commit/53aaae9c5e2a5edac5b1d2f70739a8ef7b0a9623
20 +
21 + 3. ibxscript: When parsing a store procedure or function with a variable name
22 +   enclosed in doublequotes, the double quotes are no longer removed.
23 +
24 + IBX Change Log  version (2.6-0 Build 13976) Thu, 22 Jun 2023 13:49:22 +0100
25 +
26 + NOTE: THIS VERSION RE-WRITES THE INTERNAL BUFFER MANAGER AND SHOULD BE CONSIDERED
27 +      AS BETA SOFTWARE. EVEN THOUGH IT HAS PASSED ALL REGRESSION TESTS, IT CANNOT
28 +      BE ASSUMED TO BE PRODUCTION READY UNTIL WIDER USE. PLEASE REPORT ANY
29 +      ISSUES TO support@mwasoftware.co.uk
30 +
31 + 1. Complete rewrite of internal buffer management in order to improve performance
32 +   and maintainability. Highlights:
33 +
34 +   * Extending the size of the buffer pool no longer has to copy the entire record
35 +     cache. Instead, a new extent is simply added to the buffer pool.
36 +   * A memory to memory copy of each display buffer now is avoided when scolling the
37 +     dataset.
38 +   * A separate set of buffers is now used for calculated fields. This avoids
39 +     having to keep copies of calculated field values in the buffer cache.
40 +   * Compact bitmaps are used to record null status and need to refresh in each
41 +     buffer.
42 +   * Display buffer type changed from PChar to TRecordBuffer in line with change of
43 +     buffer type in FCL-DB.
44 +
45 + 2. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is
46 +   to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure.
47 +
48 + 3. TField Provider Flags: pfRefreshOnInsert and pfRefreshOnUpdate are now supported.
49 +   If either or both of these flags are set at design time (using the fields editor)
50 +   then this forces a row refresh on respectively insert or update, or both, when the
51 +   corresponding field is not present in an SQL RETURNING clause.
52 +
53 + 4. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve
54 +   maintainability and readability and to add identification of primary key fields.
55 +
56 + 5. TIBQuery, TIBDataset and TIBTable. Traditionally, IBX has implemented the Refresh method
57 +   as a refresh of the current row. However, this is different behaviour to that described
58 +   in the FPC documentation for TDataset.Refresh which is described as "refetches the data in
59 +   the dataset from the underlying database, and attempts to reposition the cursor on
60 +   the same record as it was". IBX now complies with the FPC definition of Refresh.
61 +
62 + 6. A progammatic Row Refresh should no longer be required.
63 +   Use Insert/Update... returning to refresh any fields that may change following an
64 +   insert or update i.e. Identify fields on Insert only, Computed By, Blob and array fields
65 +   on both. If there are any other fields (e.g. updated by triggers) set the appropriate ProviderFlag
66 +   for the field at Design Time to force a row refresh if not in the returning clause.
67 +
68 + 7. It should now be possible to insert a row into an empty unidirectional dataset.
69 +
70 + 8. New TIBQuery, TIBDataSet and TIBTable property: BufferChunksInFirstBlock (default 50).
71 +   This gives the number of buffers in the initial block for the buffer pool in
72 +   bi-directional datasets. BufferChunks (default 1000) gives the number of buffers
73 +   in subsequent buffer pool blocks. This avoids large and mostly unused memory allocations
74 +   for small datasets.
75 +
76 + IBX Change Log  version (2.5-1 Build 13927) Tue, 6 Dec 2022 23:13:00 +0000
77 +
78 + 1. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead.
79 +
80 + 2. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0
81 +
82 + 3. TIBArrayGrid: change DrawCellText declaration to comply with laz 2.3.0
83 +
84 + IBX Change Log  version (2.5-0 Build 13868) Fri, 29 Jul 2022 09:52:01 +0100
85 +
86 + 1. TIBTransaction: new properties
87 +    property TransactionID: integer read GetTransactionID;
88 +    property IsReadOnly: boolean read GetIsReadOnly;
89 +    {published}
90 +    property TransactionName: string read FTransactionName write SetTransactionName;
91 +
92 + 2. IBCustomDataset: per row blob and array buffer cached clear before processing
93 +   Insert or Update...Returning. This allows blobs and arrays to be returned
94 +   by the statement.
95 +
96 + 3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
97 +
98 + 4. TransactionName initialised to a newly generated GUID if empty.
99 +
100 + 5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
101 +   for the fbintf package's journaling capability. TIBJournal is used to set the
102 +   file path and filename for the journal file and to Enabled (start journaling) and
103 +   disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
104 +   more information, and comments in IBJournal.pas.
105 +
106 + 6. TIBDatabase.InternalTransaction is now a read only transaction.
107 +
108 + 7. Bug fix: blob id no longer set to null on update when blob has not been
109 +   retrieved.
110 +
111 + 8. Row auto refreshed on update/insert if blob or array field updated and field
112 +   not in a returning clause.
113 +
114 + 9. ColumnCount moved from record buffer header to a single per dataset count. Reduces
115 +   buffer overhead and avoids problem when refresh query has a different column
116 +   count to select query i.e. incorrectly changing number of columns.
117 +
118 + 10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
119 +
120 + 11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
121 +    string. Note that the Version property returns an InterBase compatible version string.
122 +
123 + 12. IBExtract: ensure sql identifiers returned as a LIST are always quoted.
124 +
125 + IBX Change Log  version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000
126 +
127 + 1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
128 +   This is for compatibility with Firebird 5 where Update...Returning can return
129 +   a cursor.
130 +
131 + IBX Change Log  version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
132 +
133 + 1. Add try-..except check when initially loading library in IDE. This should
134 + ensure that IDE continues to load even when a failure occurs in IBX load
135 + library.
136 +
137 + 2. IBXScript: now recognises a CASE...END block within a stored procedure and
138 +   hence will correctly detect end of the outer containing block when the block
139 +   contains a SELECT ... CASE ... END construct.
140 +
141 + 3. IBExtract: some further tidying up to remove extraneous white space.
142 +
143 + 4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
144 +   errors when extra elements are added to DB.TFieldType.
145 +
146 + 5. IBUpdate: updated to reflect changes to ISQLParam.
147 +
148 + 6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
149 +
150 + 7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
151 +
152 + 8. IBSQL: Support for scrollable cursors added (note: local databases only)
153 +
154 + IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
155 +
156 + 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
157 +   exception of those defined to be one byte wide e.g. DBImplementationNo.
158 +
159 + 2. TIBSQL: Batch Update/Insert support added.
160 +
161 + 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
162 +   is no longer automatically converted to upper case when it is syntactically a
163 +   SQL Identifier. This is to support the use of stored procedures defined e.g.
164 +   as CREATE PROCEDURE "iCASE".
165 +
166 +   There could be a backwards compatibility issue when the StoredProcName was entered
167 +   manually at design time. That is not selected from the drop down list. If the
168 +   StoredProcName is entered in mixed case and the procedure was declared e.g. as
169 +   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
170 +   ensure that the value of the StoredProcName is all upper case, unless it was
171 +   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
172 +   quotes).
173 +
174 +   Note that when a stored procedure name was declared delimited in double quotes,
175 +   as in the first example above, the value of the StoredProcName property must not
176 +   include the delimiters (double quotes).
177 +
178 + 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
179 +   upgrade.conf was not found. This replaces silently ignoring the problem.
180 +
181 + 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
182 +   'Version.%.3d' and is used to generate the section header names (for a given
183 +   version no.) in the upgrade.conf file.
184 +

187   1. -c command line option added to fbsql example program. Used to set connection
