cego 14.06.2026 2.54.30 Added admin command set maxpagedelete to set up maximum number of pages marked for delete before forcing a checkpoint. This value is refreshed now with each checkpoint, so it can be adjusted hot.
cego 14.06.2026 2.54.30 Procedure cache basically works. A good example for usage is the procedure calcFibonacci, which calculates fibonacci numbers in a recursive manner :
drop if exists procedure calcFibonacci;
@
create procedure calcFibonacci(n in int) return int
begin
        var f int;
        var c int;
        if :n > 2
        then
                :f = calcFibonacci( :n - 1 ) + calcFibonacci( :n - 2 ); 
        else
                :f = 1;
        end;
        return  :f;
end;
@
With enabled proc cache, subsequent calls of calcFibonacci result in an improved performance, since the calculation is detected as static and can be cached :
CGCLT > select calcFibonacci(10);
+-------------------+
|              FUNC |
| calcFibonacci(10) |
+-------------------+
|                55 |
+-------------------+
1 tuples
ok ( 0.073 s )
CGCLT > select calcFibonacci(10);
+-------------------+
|              FUNC |
| calcFibonacci(10) |
+-------------------+
|                55 |
+-------------------+
1 tuples
ok ( 0.000 s )
cego 14.06.2026 2.54.30 Reanimation of procedure cache. This feature was still just drafted. If procedure cache is enabled, calculated static values are stored to a local procedure cache and can be retrieved for subsequent calls of this procedure. The cache values are just used for static procedure return values, e.g. if values are calculated using nested queries, cache is not used.
cego 13.06.2026 2.54.29 Version released ( including post patch )
cego 13.06.2026 2.54.28 Post patch for this version : In CegoFieldValue::castTo, changed __dateFormatLock to writeLock. This is needed, since with readlock the _dateFormatList could be traversed in parallel by the Datetime constructor. This may lead to concurreny issues
cego 13.06.2026 2.54.28 Version released
cego 13.06.2026 2.54.28 More code reorganization for CegoAuthManager, CegoQueryManager and CegoTableManager regarding the following design strategy : TableManager contains low level data access methods, QueryManger contains high level access and AuthMenager contains authorized access methods
cego 12.06.2026 2.54.28 Consolidation work done for CegoTableManager and CegoAuthManager ( including renaming from CegoQueryManager to CegoAuthManager )
cego 11.06.2026 2.54.28 Changed return code of CegoBufferPool::writeCheckPoint to int to return the exit code of the optional escape command. This exit code then is indicated in the admin console
cego 09.06.2026 2.54.27 Version released
