1 + IBX Change Log  version                                  (2.1-1) Sun, 07 Jan 2018 15:15:13 +0000
2 +
3 + 1. IBExtract: Identity columns - add addition check for null column for generator name.
4 +
5 + 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
6 +   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
7 +   information). Values returned as a result of executing an Insert or Update statement
8 +   replace existing values in the current row for each corresponding column.
9 +
10 + 3. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
11 +   When InsertSQL is generated, the Identity columns are not included in the list of values to
12 +   be inserted. A RETURNING clause is added to the insert statement to return the value of
13 +   each Identity column after the insert is executed.
14 +
15 + 4. TIBGenerator: small performance improvement by not preparing query each time
16 +   a new number is generated.
17 +
18 + 5. TIBSQL: Free resources when transaction changed.
19 +
20 + IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
21 +
22 + 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
23 +   changes.
24 +
25 + 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
26 +   Bug could result in truncated multi-byte character set values.
27 +
28 + 3. Changes consequential on moving fbintf character set utility functions from
29 +   IFirebirdAPI to IAttachment.
30 +
31 + 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
32 +
33 + 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
34 +   results in autocomplete ignoring prefix text.
35 +
36 + 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
37 +   entering a new name into the text box.
38 +
39 + 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
40 +   Firebird rather than recomputing it.
41 +
42 + 8. Property Editor positioning tidy up: All IBX Property editors should now be
43 +   screen centre. Previously some were "poDesigned" which may be inappropriate
44 +   for multi monitor desktops.
45 +
46 + 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
47 +
48 + 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
49 +    a transaction and always reset the object.
50 +
51 + 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
52 +
53 + 13. TIBXScript: Allow for override of database filename in Create Database statements.
54 +
55 + 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
56 +    to a gbak format archive.
57 +
58 + 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
59 +
60 + 16. IBLocaldb: Drop database if error creating an empty database.
61 +
62 + 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
63 +    unless selected node not in current dataset.
64 +
65 + 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
66 +    to TIBCustomService, and IBlocalDB code tidy up.
67 +
68 + 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
69 +    behaviour due to uninitialised variable.
70 +
71 + 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
72 +    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
73 +
74 + 21. IBSQL: When Database changed ensure that all resources are freed.
75 +
76 + 22. IBCustomDataset: When database changed ensure that queries an unprepared.
77 +
78 + 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
79 +    * Line Wrap on SQL Token boundaries (on user command)
80 +    * auto-complete table names in drop down list of table names
81 +    * Double click on tablename or field name adds to SQL text
82 +
83 + 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
84 +
85 + 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
86 +    TVariantArray. Seems to avoid memory corruption in Windows (probably a
87 +    workaround for a problem in fpc 3.0.4 win64).
88 +
89 + 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
90 +
91 + 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
92 +
93 + IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
94 +
95 + 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
96 +   include remote system name.
97 +
98 + 2. TIBExtract: No longer include comment header and COMMIT statement for empty
99 +   tables when data included in output.
100 +
101 + 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
102 +   and timing information to be written to stdout. This may be used to locate
103 +   performance bottlenecks.
104 +
105 + 4. SQLParser: only call "OnChanging" event handler when value is different.
106 +
107 + 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
108 +
109 + 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
110 +   that BindFields is called when the query is next activated. Avoids FieldName
111 +   not found error.
112 +
113 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
114 +   purpose and allows the programmer to define any action they want for Update, Insert
115 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
116 +   filtering of updates, or use of statements such as Grant or Revoke instead of
117 +   normal DML. See User Manual for more information.
118 +
