2. Update some examples to replace test for null date with the NullDate constant |
| 18 |

instead of zero. This is because Laz 3.0 changes the value of NullDate. |

NOTE: THIS VERSION RE-WRITES THE INTERNAL BUFFER MANAGER AND SHOULD BE CONSIDERED |
| 46 |
> |
AS BETA SOFTWARE. EVEN THOUGH IT HAS PASSED ALL REGRESSION TESTS, IT CANNOT |
| 47 |
> |
BE ASSUMED TO BE PRODUCTION READY UNTIL WIDER USE. PLEASE REPORT ANY |
| 48 |
> |
ISSUES TO support@mwasoftware.co.uk |

1. Complete rewrite of internal buffer management in order to improve performance |
| 51 |
> |
and maintainability. Highlights: |
| 52 |
> |
|
| 53 |
> |
* Extending the size of the buffer pool no longer has to copy the entire record |
| 54 |
> |
cache. Instead, a new extent is simply added to the buffer pool. |
| 55 |
> |
* A memory to memory copy of each display buffer now is avoided when scolling the |
| 56 |
> |
dataset. |
| 57 |
> |
* A separate set of buffers is now used for calculated fields. This avoids |
| 58 |
> |
having to keep copies of calculated field values in the buffer cache. |
| 59 |
> |
* Compact bitmaps are used to record null status and need to refresh in each |
| 60 |
> |
buffer. |
| 61 |
> |
* Display buffer type changed from PChar to TRecordBuffer in line with change of |
| 62 |
> |
buffer type in FCL-DB. |
| 63 |
> |
|
| 64 |
> |
2. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is |
| 65 |
> |
to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure. |
| 66 |
> |
|
| 67 |
> |
3. TField Provider Flags: pfRefreshOnInsert and pfRefreshOnUpdate are now supported. |
| 68 |
> |
If either or both of these flags are set at design time (using the fields editor) |
| 69 |
> |
then this forces a row refresh on respectively insert or update, or both, when the |
| 70 |
> |
corresponding field is not present in an SQL RETURNING clause. |
| 71 |
> |
|
| 72 |
> |
4. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve |
| 73 |
> |
maintainability and readability and to add identification of primary key fields. |
| 74 |
> |
|
| 75 |
> |
5. TIBQuery, TIBDataset and TIBTable. Traditionally, IBX has implemented the Refresh method |
| 76 |
> |
as a refresh of the current row. However, this is different behaviour to that described |
| 77 |
> |
in the FPC documentation for TDataset.Refresh which is described as "refetches the data in |
| 78 |
> |
the dataset from the underlying database, and attempts to reposition the cursor on |
| 79 |
> |
the same record as it was". IBX now complies with the FPC definition of Refresh. |
| 80 |
> |
|
| 81 |
> |
6. A progammatic Row Refresh should no longer be required. |
| 82 |
> |
Use Insert/Update... returning to refresh any fields that may change following an |
| 83 |
> |
insert or update i.e. Identify fields on Insert only, Computed By, Blob and array fields |
| 84 |
> |
on both. If there are any other fields (e.g. updated by triggers) set the appropriate ProviderFlag |
| 85 |
> |
for the field at Design Time to force a row refresh if not in the returning clause. |
| 86 |
> |
|
| 87 |
> |
7. It should now be possible to insert a row into an empty unidirectional dataset. |
| 88 |
> |
|
| 89 |
> |
8. New TIBQuery, TIBDataSet and TIBTable property: BufferChunksInFirstBlock (default 50). |
| 90 |
> |
This gives the number of buffers in the initial block for the buffer pool in |
| 91 |
> |
bi-directional datasets. BufferChunks (default 1000) gives the number of buffers |
| 92 |
> |
in subsequent buffer pool blocks. This avoids large and mostly unused memory allocations |
| 93 |
> |
for small datasets. |
