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 |

|
| 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. |

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 |

1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true. |
| 128 |

This is for compatibility with Firebird 5 where Update...Returning can return |

a cursor. |

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. |

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. |
